docs: better docs, mv doxygen to sphinx
This patch refactors the VPP sphinx docs
in order to make it easier to consume
for external readers as well as VPP developers.
It also makes sphinx the single source
of documentation, which simplifies maintenance
and operation.
Most important updates are:
- reformat the existing documentation as rst
- split RELEASE.md and move it into separate rst files
- remove section 'events'
- remove section 'archive'
- remove section 'related projects'
- remove section 'feature by release'
- remove section 'Various links'
- make (Configuration reference, CLI docs,
developer docs) top level items in the list
- move 'Use Cases' as part of 'About VPP'
- move 'Troubleshooting' as part of 'Getting Started'
- move test framework docs into 'Developer Documentation'
- add a 'Contributing' section for gerrit,
docs and other contributer related infos
- deprecate doxygen and test-docs targets
- redirect the "make doxygen" target to "make docs"
Type: refactor

All of the punted packets received on the VPP interface -will be sent to the linux counterpart, and in the reverse direction, packets sent by linux kernel will be -transmitted out the VPP interface. This plugin lays the foundation for the much easier integration of external -software with VPP. - -### Performance Monitor Plugin (perfmon) - -Another interesting feature is the performance monitor (perfmon) plugin. It allows collection of detailed low-level -CPU statistics on a per-node basis. It provides a useful advanced troubleshooting tool, should you encounter that a -specific node's performance is not on par with what it should be. Note, that the correct functioning of this plugin -may require changing the /proc/sys/kernel/perf_event_paranoid setting to enable access to the performance counters. - -### API CRC Substitution Table Removal - -And finally a clarification, not a feature per se. Some messages in the API changes table for this release have a -new marking: "message CRC32 fix". The history of this issue goes back to summer of 2020, when it was discovered that -for a considerable amount of time (several months) the calculation of the CRC of API messages was incorrect. -Specifically, all but the first user-defined types in the message failed to be included in the CRC calculation. -In plain words, this means that one might end up with a situation where client and VPP layout of message in memory -could be quite different. - -At the time of discovery, there were no API changes that were affected by that bug. However, simply fixing it meant -the CRC of about half of the VPP API messages would be altered for no reason which would result in a significant -amount of pain to the consumers of VPP. A message CRC is just an opague number for anyone using it, and the -only property of it for the user is that the messages with the same value of CRC have the same layout on the wire -with a sufficiently high certainty. - -Therefore a fix ([9f84e70c6](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=9f84e70c6)) was merged that also -contained a "band-aid" to avoid this pain. In addition to fixing the CRC generation algorithm, the fix captured -the "new" CRC values for those messages that had their CRCs arbitrarily changed by this fix and created a substituion -table with [message name, new CRC, old CRC] triplets. For a given message, if the CRC matched the recorded new -value, the code would substitute it with the old value, thus trading in a reduction in collision resistance -(two values of CRC out of 2^32 space) for not forcing users to adapt to several hundred of messages which changed -the CRCs. - -This band-aid also had the property that whenever a message did change the definition, it would automatically get -a "correct" calculation of CRC32 and no longer use the slot in the table. The table naturally shrinks over -time, thus allowing a painless transition, while also preserving the integrity check for the affected messages. -If any fields changed, the CRC would no longer match the "new" value thus no substitution would be made. Since the -choice of CRC32 is just an implementation detail which is supposed to be opaque to the user, the band-aid was deemed -a reasonable approach to avoid a major burden on VPP consumers. - -However, in practice this solution was not accepted well. After a notification period, the API CRC Substitution table -was removed by the patch ([da1b76aa8](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=da1b76aa8)). Thus all of the -API CRC changes that did not happen in 9f84e70c6, happened in da1b76aa8. Hopefully the notification of these changes -has reduced the inconvenience. VPP users are asked to not rely on any other property of the message CRC other than -changes to its value when the message layout changes. - -## Features - -- Binary API Compiler for Python - - Support an 'autoendian' keyword for message definitions in .api files ([9302cfea9](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=9302cfea9)) -- Build System -

FD.io VPP 20.09 release comprises more than 562 commits since the previous -release, including 274 fixes. Notable changes in this release were the Virtio -driver adding packet buffering on the transmit path to handle slow back-ends -which often have jitter and delays in free'ing buffers, and also adding support -for Virtio 1.1 packed rings. FD.io VPP IPSEC added support for multi-point on -IPSec interfaces, brings the meshed benefits of IP to IPSec tunnels. The FD.io -VPP Cloud NAT (CNAT), added support source NAT ICMP and DHCP. The FD.io VPP FIB -added support for source address selection (SAS) and flow hashing on the inner -packets. Finally the FD.io VPP Perfmon plugin has been substantially rewritten, -to support measuring bundles of counters, and reporting statistics per graph -node. - -Reflecting the API change policy introduced in the 20.09, please review the -following sections below: -- Newly deprecated API messages: please note that if you are using a deprecated -message, they will soon be removed in a subsequent release. Collaborate with -the feature maintainer on the best approach to mitigate. -- In-progress API messages: They are work-in-progress, and are *not* subject to -the policy, and may change or even be removed at any time. Please collaborate -with the feature maintainer on plans to productize the message before using in -any product. In-progress APIs must eventually become stable or be removed. - -## Features - -- Binary API Libraries - - Vat2 and JSON autogeneration for API messages ([df87f8092](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=df87f8092)) -- Plugins - - AF\_XDP driver - - Add option to claim all available RX queues ([d4e109138](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=d4e109138)) - - CNat - - Disable default scanner process ([d63f73b83](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=d63f73b83)) - - IP ICMP error support ([ece39214b](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=ece39214b)) - - Add support for SNat ICMP ([613b2c3c7](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=613b2c3c7)) - - Introduce parametric source policy ([ce25b60de](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=ce25b60de)) - - Add DHCP support ([af897c5e3](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=af897c5e3)) - - Crypto - ipsecmb - - Bump to intel-ipsec-mb version 0.55 ([b5df85e24](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=b5df85e24)) - - DPDK - - Call the meson-based build instead of Makefiles ([4c4633cad](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=4c4633cad)) - - Telemetry thread is off by default.

- -@page release_notes_2009 Release notes for VPP 20.09 - -More than 458 commits since the previous release, including 266 fixes. - -## Release Highlights - -The FD.io VPP 20.09 release added a number of notable new features. In plugins, -the I/O layer added support for the Linux AF\_XDP interface with the AF\_XDP -plugin. New plugins where added supporting both the Wireguard security protocol -and CNAT destination based address translation, and the existing IKEv2 plugin -added support for NAT-T. In the cryptography layer, support was added for -synchronous software crypto engines, enabling users to allocate dedicated crypto -worker threads. The flow layer added support for steering IPSEC ESP/AH flows to -worker threads. GRO support was added to the packet coalescing library. - -This release introduces the new FD.io VPP API change policy to ensure -backwards-compatibility. The policy will ensure seamless upgrades to new -versions of FD.io VPP in future, provided no "in-progress" or deprecated APIs -are in use. Enabling the FD.io community to enjoy the benefits of new releases, -while minimizing the work involved in staying current. - -If you dive into the implementation, you will note that policy in action. A -number of modified API messages have had their original versions maintained to -ensure compatibility. - -Reflecting the new policy we added two new sections to the release notes -describing: -- Newly deprecated API messages: please note that if you are using a deprecated -message, they will soon be removed in a subsequent release. Collaborate with -the feature maintainer on the best approach to mitigate. -- In-progress API messages: They are work-in-progress, and are *not* subject to -the policy, and may change or even be removed at any time. Please collaborate -with the feature maintainer on plans to productize the message before using in -any product. In-progress APIs must eventually become stable or be removed. - -## Features - -- VNET - - Crypto Infra - - Add chacha20-poly1305 algo (61f49aa38) - - Asynchronous crypto engines (2284817ea) - - Add

- Add support for IP-IP - - Add vxlan tunnel support -- VRRP - - Add plugin providing VRRP support - -### Ongoing Work On More Semantic-Typed API - -This release, like the 20.01, continues the journey on defining -the semantic-based types instead of storage-based types within the API, -so you may have noticed this in the API changes. - -Some of the changes -are related to the infrastructure, and may be bugfixes, they -do not change the CRC of the message but affect the representation -on the wire. One particular commit we want you to pay attention to, -is [b5c0d35f](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=b5c0d35f), which -fixes the bug with the enum representation on the wire - before it, -even the enums declared as u8 or u16 were represented as u32 in -the API messages. - -Another important commit we would like to call out explicitly as well is -[7dd63e5c](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=7dd63e5c), which -pinned the address_family and ip_proto enum types to be u8 instead of the default u32. - -The above two commits will be primarily interesting for those who work with the low-level -APIs on VPP - the API frameworks should make these under-the-hood changes transparent. -However, we decided to call these out, given that for those affected these will -be pretty important changes. - -Another commit, that does not have the immediate impact at the moment, but that -is poised to improve the user interaction with the API is [5c318c70](https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=5c318c70). -This adds the tooling and ability to implement a structured process, -by which the API messages can evolve, while minimizing the impact to the -API users. -

It maps a C struct directly onto on-the-wire API messages. -The client side C language binding is the same, while other language bindings have their own encoder/decoders. - -Multiple strings alone or combined with other variable length types turned out to be error prone to manually implement on the VPP side, -and not supported by VPP API (VAPI) very well at all. - -To avoid having to rewrite VAPI significantly, and to mitigate the risk -and error prone server side support of multiple variable length fields, -this patch extends strings to have a fixed size (on the wire) and -a variable flavour, as well as adding detection in the API compiler -to detect multiple variable length fields in a message (or type). - -Given that this change breaks the commitment to binary API compatibility, -normally present in point builds, ALL 19.08 build artifacts are being -deferred. - -This means the artifacts for the VPP 19.08.1 will be installed -in the release repository (packagecloud.io/fdio/release), then -ALL 19.08 build artifacts will be moved into the deferred repository -(packagecloud.io/fdio/deferred). The 19.08 artifacts will always be -available for archive purposes in the deferred repository. - -During the further testing by Networking-VPP team, they discovered -another issue documented in VPP-1769 - which requires a CRC-affecting -fix in https://gerrit.fd.io/r/#/c/vpp/+/22015/ - so the 19.08.1 -will contain the fixes for both issues. - -These two changes have resulted in the following

Given +the exceptional nature of the change, also including the text here: + +Bug: https://gerrit.fd.io/r/c/vpp/+/21492 + +Variable length strings were committed to VPP in 413f4a5b. The VPP +server side of the API does not use a wire encoder/decoder. It maps a C +struct directly onto on-the-wire API messages. The client side C +language binding is the same, while other language bindings have their +own encoder/decoders. + +Multiple strings alone or combined with other variable length types +turned out to be error prone to manually implement on the VPP side, and +not supported by VPP API (VAPI) very well at all. + +To avoid having to rewrite VAPI significantly, and to mitigate the risk +and error prone server side support of multiple variable length fields, +this patch extends strings to have a fixed size (on the wire) and a +variable flavour, as well as adding detection in the API compiler to +detect multiple variable length fields in a message (or type). + +Given that this change breaks the commitment to binary API +compatibility, normally present in point builds, ALL 19.08 build +artifacts are being deferred. + +This means the artifacts for the VPP 19.08.1 will be installed in the +release repository (packagecloud.io/fdio/release), then ALL 19.08 build +artifacts will be moved into the deferred repository +(packagecloud.io/fdio/deferred).

They are mentioned in the below “features” section as +well, together with the corresponding commits. + +- TAP Drivers + + - Implement sw_interface_tap_v2_dump filtering by sw_if_index + - Add support for persistence + +- Native Virtio Drivers + + - Support virtio 1.1 packed ring in vhost + +- gso + + - Add support for IP-IP + - Add vxlan tunnel support + +- VRRP + + - Add plugin providing VRRP support + +Ongoing Work On More Semantic-Typed API +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This release, like the 20.01, continues the journey on defining the +semantic-based types instead of storage-based types within the API, so +you may have noticed this in the API changes. + +Some of the changes are related to the infrastructure, and may be +bugfixes, they do not change the CRC of the message but affect the +representation on the wire. One particular commit we want you to pay +attention to, is +`b5c0d35f <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=b5c0d35f>`__, +which fixes the bug with the enum representation on the wire - before +it, even the enums declared as u8 or u16 were represented as u32 in the +API messages. + +Another important commit we would like to call out explicitly as well is +`7dd63e5c <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=7dd63e5c>`__, +which pinned the address_family and ip_proto enum types to be u8 instead +of the default u32. + +The above two commits will be primarily interesting for those who work +with the low-level APIs on VPP - the API frameworks should make these +under-the-hood changes transparent. However, we decided to call these +out, given that for those affected these will be pretty important +changes. + +Another commit, that does not have the immediate impact at the moment, +but that is poised to improve the user interaction with the API is +`5c318c70 <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=5c318c70>`__. +This adds the tooling and ability to implement a structured process, by +which the API messages can evolve, while minimizing the impact to the +API users. + +Features +-------- + +- Binary API Compiler for Python + + - Api crc checker (5c318c70d) + +- Binary API Libraries + + - Add macro that zeros out api reply buffer (f24de1795) + +- Build System + + - Add snap packaging (experimental) (6d97e62c0) + - Support arch-specific compiling for Neoverse N1 (690ce8672) + +- Crypto native Plugin + + - Add ARMv8 AES-CBC implementation (776644efe) + - Add AArch64 AES-GCM native implementation (622b5ce61) + - Calculate ghash using vpclmulqdq instructions (627fb6a16) + - GCM implementation with vector AESNI instructions (47d8f5dcd) + +- Infrastructure Library + + - Add x86 CPU definitions (38e0413b2) + - Numa vector placement support (a690fdbfe) + - Add cmake option to grow vectors by 1 (98bd75778) + - Add tw_timer_2t_2w_512sl variant (907678977) + +- Link Bonding + + - Add GSO support (2e1fa54b7) + +- Plugins + + - DPDK + + - Output switch information (2347278d9) + - Use port_id as interface name suffix for representors + (a80f8f371) + - Add iova-mode to startup (4e96ddaec) + - Bump DPDK version to 20.02 (76be887d8) + - Enable DPDK iAVF PMD (162ea767c) + - DPDK 20.05 iavf flow director backporting to DPDK 20.02 + (7f83738b4) + + - GTPU + + - Offload RX flow (00fdf53c7) + - RX offload for IPv6 payload supporting (ed63a0ff7) + + - Host Stack Applications + + - Proxy rcv wnd update acks after full fifos (dda2dbeda) + + - IPv6 Segment Routing Mobile + + - Support GTP4/6.DT and User Plane message mapping (9e722bd46) + + - Internet Key Exchange (IKEv2) Protocol + + - Configure a profile with an existing interface (44476c6b2) + - Responder honours the protected tunnel config (685001f0a) + - Add support for custom ipsec-over-udp port (e5d34919b) + - Dead peer detection (c415d0a8e) + + - NAT + + - In2out-output nodes work with acl reflect (d539e256b) + - Api & cli command for forcing session cleanup (edf777272) + - Dslite ce mode in separate config entry (958919f36) + + - QUIC protocol + + - Update quicly to v0.0.10-VPP (62b1cea6e) + - Quicly crypto offloading (92de6b65b) + - Check quicly version tag at compile time (ffdc72da4) + + - RDMA (ibverb) driver + + - Bunp rdma-core version to v28.0 (eb89b9093) + - Add Mellanox mlx5 Direct Verbs receive support (dd648aac0) + - Introduce direct verb for Cx4/5 tx (dc812d9a7) + + - Unicast Reverse Path forwarding + + - Unicast reverse Path Forwarding (plugin) (d724e4f43) + + - VRRP + + - Add plugin providing vrrp support (39e9428b9) + +- SVM Library + + - Numa awareness for ssvm segments (6fe8998fe) + - Support multi-chunk fifo chunk alloc (8e755a16a) + - Chunk alloc stats (d35887297) + - New FIFO design/architecture (f22f4e562) + - Fifo test (64e96613d) + +- Test Infrastructure + + - Add running_gcov_tests to framework.py (d498c9eb2) + - Implement ipaddress convenience methods (e64e5fff4) + +- VNET + + - Crypto Infra + + - Add chained buffer support in ipsecmb (AES-GCM) (2fc409131) + - Add support for testing quad loops in crypto algos (a9075dcf6) + - Introduce async crypto infra (f539578ba) + + - Ethernet + + - Configure system default ethernet MTU (5fa452554) + + - FLOW + + - Add vlan tagged types for IPv4/IPv6 5-tuple flows (f13830ce7) + - Add RSS support (24e2c50bf) + - Add l2tpv3oip flow (8b43aaaf1) + + - GRE + + - Tunnel encap/decap flags (e5b94dded) + + - GSO + + - Add vxlan tunnel support (0b04209ed) + - Add support for IP-IP (84f91fa9c) + + - IP Neighbors + + - Populate neighbor age via API (9c1928f81) + - Replace feature for the ip-neighbor data-base (c87fbb417) + - Add flush API (240dcb24a) + + - IPIP + + - Multi-point interface (14053c9db) + + - IPSec + + - Add support for chained buffers (efcad1a9d) + - IPSec protection for multi-point tunnel interfaces (282872127) + - Add input node bypass/discard functionality (0546483ce) + - User can choose the UDP source port (abc5660c6) + - Support 4o6 and 6o4 for SPD tunnel mode SAs (b1fd80f09) + + - IPv4 LPM + + - More detailed show reassembly commands (a877cf9f3) + - Replace Sematics for Interface IP addresses (59f71132e) + + - MPLS + + - Add user defined name tag to mpls tunnels (39ae0a07a) + + - Native Virtio Drivers + + - Support virtio 1.1 packed ring in vhost (bc0d9ff67) + + - Packet Generator + + - Set vnet buffer flags in pg streams (08eb2bb20) + + - Segment Routing (IPv6 and MPLS) + + - Change the CLI keyword from address to prefix.

+=========================== + +More than 458 commits since the previous release, including 266 fixes. + +Release Highlights +------------------ + +The FD.io VPP 20.09 release added a number of notable new features. In +plugins, the I/O layer added support for the Linux AF_XDP interface with +the AF_XDP plugin. New plugins where added supporting both the Wireguard +security protocol and CNAT destination based address translation, and +the existing IKEv2 plugin added support for NAT-T. In the cryptography +layer, support was added for synchronous software crypto engines, +enabling users to allocate dedicated crypto worker threads. The flow +layer added support for steering IPSEC ESP/AH flows to worker threads. +GRO support was added to the packet coalescing library. + +This release introduces the new FD.io VPP API change policy to ensure +backwards-compatibility. The policy will ensure seamless upgrades to new +versions of FD.io VPP in future, provided no “in-progress” or deprecated +APIs are in use. Enabling the FD.io community to enjoy the benefits of +new releases, while minimizing the work involved in staying current. + +If you dive into the implementation, you will note that policy in +action. A number of modified API messages have had their original +versions maintained to ensure compatibility. + +Reflecting the new policy we added two new sections to the release notes +describing: - Newly deprecated API messages: please note that if you are +using a deprecated message, they will soon be removed in a subsequent +release. Collaborate with the feature maintainer on the best approach to +mitigate. - In-progress API messages: They are work-in-progress, and are +*not* subject to the policy, and may change or even be removed at any +time. Please collaborate with the feature maintainer on plans to +productize the message before using in any product. In-progress APIs +must eventually become stable or be removed. + +Features +-------- + +- VNET + + - Crypto Infra + + - Add chacha20-poly1305 algo (61f49aa38) + - Asynchronous crypto engines

Highlights +------------------ + +The FD.io VPP 20.09 release comprises more than 562 commits since the +previous release, including 274 fixes. Notable changes in this release +were the Virtio driver adding packet buffering on the transmit path to +handle slow back-ends which often have jitter and delays in free’ing +buffers, and also adding support for Virtio 1.1 packed rings. FD.io VPP +IPSEC added support for multi-point on IPSec interfaces, brings the +meshed benefits of IP to IPSec tunnels. The FD.io VPP Cloud NAT (CNAT), +added support source NAT ICMP and DHCP. The FD.io VPP FIB added support +for source address selection (SAS) and flow hashing on the inner +packets. Finally the FD.io VPP Perfmon plugin has been substantially +rewritten, to support measuring bundles of counters, and reporting +statistics per graph node. + +Reflecting the API change policy introduced in the 20.09, please review +the following sections below: - Newly deprecated API messages: please +note that if you are using a deprecated message, they will soon be +removed in a subsequent release. Collaborate with the feature maintainer +on the best approach to mitigate. - In-progress API messages: They are +work-in-progress, and are *not* subject to the policy, and may change or +even be removed at any time. Please collaborate with the feature +maintainer on plans to productize the message before using in any +product. In-progress APIs must eventually become stable or be removed. + +Features +-------- + +- Binary API Libraries + + - Vat2 and JSON autogeneration for API messages + (`df87f8092 <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=df87f8092>`__) + +- Plugins + + -

+=========================== + +More than 787 commits since the previous release, including 364 fixes. + +Release Highlights +------------------ + +There are many excellent new features in this release, however a few of +them deserve a special mention. + +Linux Control Plane Plugin (linux-cp) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +One of the more significant new features included in this release is a +linux control plane (linux-cp) plugin. It enables the near-seamless +integration of VPP with the host control plane, by mirroring the VPP +interfaces into a TUN or TAP device created in the linux kernel. All of +the punted packets received on the VPP interface will be sent to the +linux counterpart, and in the reverse direction, packets sent by linux +kernel will be transmitted out the VPP interface. This plugin lays the +foundation for the much easier integration of external software with +VPP. + +Performance Monitor Plugin (perfmon) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Another interesting feature is the performance monitor (perfmon) plugin. +It allows collection of detailed low-level CPU statistics on a per-node +basis. It provides a useful advanced troubleshooting tool, should you +encounter that a specific node’s performance is not on par with what it +should be. Note, that the correct functioning of this plugin may require +changing the /proc/sys/kernel/perf_event_paranoid setting to enable +access to the performance counters. + +API CRC Substitution Table Removal +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +And finally a clarification, not a feature per se. Some messages in the +API changes table for this release have a new marking: “message CRC32 +fix”. The history of this issue goes back to summer of 2020, when it was +discovered that for a considerable amount of time (several months) the +calculation of the CRC of API messages was incorrect. Specifically, all +but the first user-defined types in the message failed to be included in +the CRC calculation. In plain words, this means that one might end up +with a situation where client and VPP layout of message in memory could +be quite different. + +At the time of discovery, there were no API changes that were affected +by that bug. However, simply fixing it meant the CRC of about half of +the VPP API messages would be altered for no reason which would result +in a significant amount of pain to the consumers of VPP. A message CRC +is just an opague number for anyone using it, and the only property of +it for the user is that the messages with the same value of CRC have the +same layout on the wire with a sufficiently high certainty. + +Therefore a fix +(`9f84e70c6 <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=9f84e70c6>`__) +was merged that also contained a “band-aid” to avoid this pain. In +addition to fixing the CRC generation algorithm, the fix captured the +“new” CRC values for those messages that had their CRCs arbitrarily +changed by this fix and created a substituion table with [message name, +new CRC, old CRC] triplets. For a given message, if the CRC matched the +recorded new value, the code would substitute it with the old value, +thus trading in a reduction in collision resistance (two values of CRC +out of 2^32 space) for not forcing users to adapt to several hundred of +messages which changed the CRCs. + +This band-aid also had the property that whenever a message did change +the definition, it would automatically get a “correct” calculation of +CRC32 and no longer use the slot in the table. The table naturally +shrinks over time, thus allowing a painless transition, while also +preserving the integrity check for the affected messages. If any fields +changed, the CRC would no longer match the “new” value thus no +substitution would be made. Since the choice of CRC32 is just an +implementation detail which is supposed to be opaque to the user, the +band-aid was deemed a reasonable approach to avoid a major burden on VPP +consumers. + +However, in practice this solution was not accepted well. After a +notification period, the API CRC Substitution table was removed by the +patch +(`da1b76aa8 <https://gerrit.fd.io/r/gitweb?p=vpp.git;a=commit;h=da1b76aa8>`__). +Thus all of the API CRC changes that did not happen in 9f84e70c6, +happened in da1b76aa8. Hopefully the notification of these changes has +reduced the inconvenience. VPP users are asked to not rely on any other +property of the message CRC other than changes to its value when the +message layout changes. + +Features +-------- + +- Binary API Compiler for Python + + -

equipped with a set of commands that are useful +for debugging. + +The easiest way to access the CLI (with proper permissions) is to use the +vppctl command: + +.. code-block:: console + + sudo vppctl <cli-command> + + +The CLI parser matches static keyword strings, eventually invoking an action +function. Unambiguous partial keyword matching always occurs. The action +functions consume input until satisfied or until they fail. This model makes +for easy coding, but does not guarantee useful "help" output. It's up to the +CLI command writer to add useful help strings. + +You can find the source code of CLI commands by searching for instances of the +``VLIB_CLI_COMMAND`` macro in the code source files. + +Please help maintain and improve this document to make and keep these commands +clear and useful! + +.. _debug_telnet_cli: + +Debug and Telnet CLI +-------------------- + +The debug CLI is enabled with the unix interactive parameter or startup +configuration option. This causes VPP to start without daemonizing and +presents a command line interface on the terminal where it is run. + +The Telnet CLI is enabled with the ``cli-listen localhost:5002`` option which +will cause VPP to listen for TCP connections on the localhost address port +``5002``. A Telnet client can then connect to this port (for example, ``telnet +localhost 5002``) and will receive a command line prompt. + +This configuration will enable both mechanisms: + +.. code-block:: console + + unix { + interactive + cli-listen localhost:5002 + } + + +The debug CLI can operate in line mode, which may be useful when running +inside an IDE like Emacs.

Several other options exist that alter how this +CLI works, see the @ref syscfg section for details. + +The CLI starts with a banner graphic (which can be disabled) and a prompt. The +prompt will typically read ``vpp`` for a release version of VPP and ``DBGvpp#`` +for a development version with debugging enabled, for example: + +.. code-block:: console + + _______ _ _ _____ ___ + __/ __/ _ \ (_)__ | | / / _ \/ _ \ + _/ _// // / / / _ \ | |/ / ___/ ___/ + /_/ /____(_)_/\___/ |___/_/ /_/ + + vpp# + + + +versus: + +.. code-block:: console + + _______ _ _ _____ ___ + __/ __/ _ \ (_)__ | | / / _ \/ _ \ + _/ _// // / / / _ \ | |/ / ___/ ___/ + /_/ /____(_)_/\___/ |___/_/ /_/ + + DBGvpp# + + +This prompt can be configured with the ``unix cli-prompt`` setting and the +banner is disabled with ``unix cli-no-banner``. + +.. _cli_features: + +CLI features +------------ + +The CLI has several editing features that make it easy to use. + +- Cursor keys ``left/right`` will move the cursor within a command line; + typing will insert at the cursor; erase will erase at the cursor. + +- ``Ctrl-left/right`` will search for the start of the next word to + the left or right. +- ``Home/end`` will jump the cursor to the start and end of the line. +- Cursor keys up/down and ``^P/^N`` iterate through the command history + buffer.

At this point, we use the next log2_size bits from the hash code +to select the specific backing page in which the (key,value) page will +be found. + +Net result: we search **one** backing page, not 2**log2_size pages. This +is a key property of the algorithm. + +When sufficient collisions occur to fill the backing pages for a given +bucket, we double the bucket size, rehash, and deal the bucket contents +into a double-sized set of backing pages. In the future, we may +represent the size as a linear combination of two powers-of-two, to +increase space efficiency. + +To solve the “jackpot case” where a set of records collide under hashing +in a bad way, the implementation will fall back to linear search across +2**log2_size backing pages on a per-bucket basis. + +To maintain *space* efficiency, we should configure the bucket array so +that backing pages are effectively utilized. Lookup performance tends to +change *very little* if the bucket array is too small or too large. + +Bihash depends on selecting an effective hash function. If one were to +use a truly broken hash function such as “return 1ULL.” bihash would +still work, but it would be equivalent to poorly-programmed linear +search. + +We often use cpu intrinsic functions - think crc32 - to rapidly compute +a hash code which has decent statistics. + +Bihash Cookbook +--------------- + +Using current (key,value) template instance types +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +It’s quite easy to use one of the template instance types.

The BVT macro concatenates its argument with the +value of BIHASH_TYPE and the fixed-string “_t”. So in the above example, +BVT (clib_bihash) generates “clib_bihash_8_8_t”. + +If you’re sure you won’t decide to change the template / type name +later, it’s perfectly OK to code “clib_bihash_8_8_t” and so forth. + +In fact, if you #include multiple template instances in a single source +file, you **must** use fully-enumerated type names.

Call 2x BV(clib_bihash_prefetch_bucket) to +prefetch the buckets \* 2 packets ahead, call 2x +BV(clib_bihash_prefetch_data) to prefetch 2x (key,value) data pages. \* +In the processing section, call 2x +BV(clib_bihash_search_inline_with_hash) to perform the search + +Programmer’s choice whether to stash the hash code somewhere in +vnet_buffer(b) metadata, or to use local variables. + +Single-loop: \* Use simple search as shown above. + +Walking a bihash table +~~~~~~~~~~~~~~~~~~~~~~ + +A fairly common scenario to build “show” commands involves walking a +bihash table. It’s simple enough: + +.. code:: c + + my_main_t *mm = &my_main; + clib_bihash_8_8_t *h; + void callback_fn (clib_bihash_kv_8_8_t *, void *); + + h = &mm->hash_table; + + BV(clib_bihash_foreach_key_value_pair) (h, callback_fn, (void *) arg); + +To nobody’s great surprise: clib_bihash_foreach_key_value_pair iterates +across the entire table, calling callback_fn with active entries. + +Bihash table iteration safety +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The iterator template “clib_bihash_foreach_key_value_pair” must be used +with a certain amount of care. For one thing, the iterator template does +*not* take the bihash hash table writer lock. If your use-case requires +it, lock the table. + +For another, the iterator template is not safe under all conditions: + +- It’s **OK to delete** bihash table entries during a table-walk. The + iterator checks whether the current bucket has been freed after each + *callback_fn(…)* invocation. + +- It is **not OK to add** entries during a table-walk. + +The add-during-walk case involves a jackpot: while processing a +key-value-pair in a particular bucket, add a certain number of entries. +By luck, assume that one or more of the added entries causes the +**current bucket** to split-and-rehash. + +Since we rehash KVP’s to different pages based on what amounts to a +different hash function, either of these things can go wrong: + +- We may revisit previously-visited entries. Depending on how one coded + the use-case, we could end up in a recursive-add situation. + +- We may skip entries that have not been visited + +One could build an add-safe iterator, at a significant cost in +performance: copy the entire bucket, and walk the copy. + +It’s hard to imagine a worthwhile add-during walk use-case in the first +place; let alone one which couldn’t be implemented by walking the table +without modifying it, then adding a set of records. + +Creating a new template instance +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Creating a new template is easy. Use one of the existing templates as a +model, and make the obvious changes. The hash and key_compare methods +are performance-critical in multiple senses. + +If the key compare method is slow, every lookup will be slow. If the +hash function is slow, same story. If the hash function has poor +statistical properties, space efficiency will suffer. In the limit, a +bad enough hash function will cause large portions of the table to +revert to linear search. + +Use of the best available vector unit is well worth the trouble in the +hash and key_compare functions. diff --git a/docs/developer/corearchitecture/buffer_metadata.rst b/docs/developer/corearchitecture/buffer_metadata.rst new file mode 100644 index 00000000000..545c31f3041 --- /dev/null +++ b/docs/developer/corearchitecture/buffer_metadata.rst @@ -0,0 +1,237 @@ +Buffer Metadata +=============== + +Each vlib_buffer_t (packet buffer) carries buffer metadata which +describes the current packet-processing state.

It also +provides high-performance dynamic arrays, hashes, bitmaps, +high-precision real-time clock support, fine-grained event-logging, and +data structure serialization. + +One fair comment / fair warning about vppinfra: you can't always tell a +macro from an inline function from an ordinary function simply by name. +Macros are used to avoid function calls in the typical case, and to +cause (intentional) side-effects. + +Vppinfra has been around for almost 20 years and tends not to change +frequently. The VPP Infrastructure layer contains the following +functions: + +Vectors +------- + +Vppinfra vectors are ubiquitous dynamically resized arrays with by user +defined "headers". Many vpppinfra data structures (e.g. hash, heap, +pool) are vectors with various different headers. + +The memory layout looks like this: + +:: + + User header (optional, uword aligned) + Alignment padding (if needed) + Vector length in elements + User's pointer -> Vector element 0 + Vector element 1 + ... + Vector element N-1 + +As shown above, the vector APIs deal with pointers to the 0th element of +a vector. Null pointers are valid vectors of length zero. + +To avoid thrashing the memory allocator, one often resets the length of +a vector to zero while retaining the memory allocation. Set the vector +length field to zero via the vec_reset_length(v) macro. [Use the macro! +It’s smart about NULL pointers.] + +Typically, the user header is not present. User headers allow for other +data structures to be built atop vppinfra vectors. Users may specify the +alignment for first data element of a vector via the [vec]()*_aligned +macros. + +Vector elements can be any C type e.g. (int, double, struct bar). This +is also true for data types built atop vectors (e.g. heap, pool, etc.). +Many macros have \_a variants supporting alignment of vector elements +and \_h variants supporting non-zero-length vector headers. The \_ha +variants support both. Additionally cacheline alignment within a vector +element structure can be specified using the +``[CLIB_CACHE_LINE_ALIGN_MARK]()`` macro. + +Inconsistent usage of header and/or alignment related macro variants +will cause delayed, confusing failures. + +Standard programming error: memorize a pointer to the ith element of a +vector, and then expand the vector. Vectors expand by 3/2, so such code +may appear to work for a period of time. Correct code almost always +memorizes vector **indices** which are invariant across reallocations. + +In typical application images, one supplies a set of global functions +designed to be called from gdb. Here are a few examples: + +- vl(v) - prints vec_len(v) +- pe(p) - prints pool_elts(p) +- pifi(p, index) - prints pool_is_free_index(p, index) +- debug_hex_bytes (p, nbytes) - hex memory dump nbytes starting at p + +Use the “show gdb” debug CLI command to print the current set. + +Bitmaps +------- + +Vppinfra bitmaps are dynamic, built using the vppinfra vector APIs. +Quite handy for a variety jobs. + +Pools +----- + +Vppinfra pools combine vectors and bitmaps to rapidly allocate and free +fixed-size data structures with independent lifetimes. Pools are perfect +for allocating per-session structures. + +Hashes +------ + +Vppinfra provides several hash flavors. Data plane problems involving +packet classification / session lookup often use +./src/vppinfra/bihash_template.[ch] bounded-index extensible hashes. +These templates are instantiated multiple times, to efficiently service +different fixed-key sizes. + +Bihashes are thread-safe. Read-locking is not required. A simple +spin-lock ensures that only one thread writes an entry at a time. + +The original vppinfra hash implementation in ./src/vppinfra/hash.[ch] +are simple to use, and are often used in control-plane code which needs +exact-string-matching. + +In either case, one almost always looks up a key in a hash table to +obtain an index in a related vector or pool. The APIs are simple enough, +but one must take care when using the unmanaged arbitrary-sized key +variant. Hash_set_mem (hash_table, key_pointer, value) memorizes +key_pointer. It is usually a bad mistake to pass the address of a vector +element as the second argument to hash_set_mem. It is perfectly fine to +memorize constant string addresses in the text segment. + +Timekeeping +----------- + +Vppinfra includes high-precision, low-cost timing services. The datatype +clib_time_t and associated functions reside in ./src/vppinfra/time.[ch]. +Call clib_time_init (clib_time_t \*cp) to initialize the clib_time_t +object. + +Clib_time_init(…) can use a variety of different ways to establish the +hardware clock frequency. At the end of the day, vppinfra timekeeping +takes the attitude that the operating system’s clock is the closest +thing to a gold standard it has handy. + +When properly configured, NTP maintains kernel clock synchronization +with a highly accurate off-premises reference clock. Notwithstanding +network propagation delays, a synchronized NTP client will keep the +kernel clock accurate to within 50ms or so. + +Why should one care? Simply put, oscillators used to generate CPU ticks +aren’t super accurate. They work pretty well, but a 0.1% error wouldn’t +be out of the question. That’s a minute and a half’s worth of error in 1 +day. The error changes constantly, due to temperature variation, and a +host of other physical factors. + +It’s far too expensive to use system calls for timing, so we’re left +with the problem of continuously adjusting our view of the CPU tick +register’s clocks_per_second parameter. + +The clock rate adjustment algorithm measures the number of cpu ticks and +the “gold standard” reference time across an interval of approximately +16 seconds. We calculate clocks_per_second for the interval: use rdtsc +(on x86_64) and a system call to get the latest cpu tick count and the +kernel’s latest nanosecond timestamp. We subtract the previous interval +end values, and use exponential smoothing to merge the new clock rate +sample into the clocks_per_second parameter. + +As of this writing, we maintain the clock rate by way of the following +first-order differential equation: + +.. code:: c + + clocks_per_second(t) = clocks_per_second(t-1) * K + sample_cps(t)*(1-K) + where K = e**(-1.0/3.75); + +This yields a per observation “half-life” of 1 minute. Empirically, the +clock rate converges within 5 minutes, and appears to maintain +near-perfect agreement with the kernel clock in the face of ongoing NTP +time adjustments. + +See ./src/vppinfra/time.c:clib_time_verify_frequency(…) to look at the +rate adjustment algorithm. The code rejects frequency samples +corresponding to the sort of adjustment which might occur if someone +changes the gold standard kernel clock by several seconds. + +Monotonic timebase support +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Particularly during system initialization, the “gold standard” system +reference clock can change by a large amount, in an instant. It’s not a +best practice to yank the reference clock - in either direction - by +hours or days. In fact, some poorly-constructed use-cases do so. + +To deal with this reality, clib_time_now(…) returns the number of +seconds since vpp started, *guaranteed to be monotonically increasing, +no matter what happens to the system reference clock*. + +This is first-order important, to avoid breaking every active timer in +the system. The vpp host stack alone may account for tens of millions of +active timers. It’s utterly impractical to track down and fix timers, so +we must deal with the issue at the timebase level. + +Here’s how it works. Prior to adjusting the clock rate, we collect the +kernel reference clock and the cpu clock: + +.. code:: c + + /* Ask the kernel and the CPU what time it is... */ + now_reference = unix_time_now (); + now_clock = clib_cpu_time_now (); + +Compute changes for both clocks since the last rate adjustment, roughly +15 seconds ago: + +.. code:: c + + /* Compute change in the reference clock */ + delta_reference = now_reference - c->last_verify_reference_time; + + /* And change in the CPU clock */ + delta_clock_in_seconds = (f64) (now_clock - c->last_verify_cpu_time) * + c->seconds_per_clock; + +Delta_reference is key. Almost 100% of the time, delta_reference and +delta_clock_in_seconds are identical modulo one system-call time. +However, NTP or a privileged user can yank the system reference time - +in either direction - by an hour, a day, or a decade. + +As described above, clib_time_now(…) must return monotonically +increasing answers to the question “how long has it been since vpp +started, in seconds.” To do that, the clock rate adjustment algorithm +begins by recomputing the initial reference time: + +.. code:: c + + c->init_reference_time += (delta_reference - delta_clock_in_seconds); + +It’s easy to convince yourself that if the reference clock changes by +15.000000 seconds and the cpu clock tick time changes by 15.000000 +seconds, the initial reference time won’t change. + +If, on the other hand, delta_reference is -86400.0 and delta clock is +15.0 - reference time jumped backwards by exactly one day in a 15-second +rate update interval - we add -86415.0 to the initial reference time. + +Given the corrected initial reference time, we recompute the total +number of cpu ticks which have occurred since the corrected initial +reference time, at the current clock tick rate: + +.. code:: c + + c->total_cpu_time = (now_reference - c->init_reference_time) + * c->clocks_per_second; + +Timebase precision +~~~~~~~~~~~~~~~~~~ + +Cognoscenti may notice that vlib/clib_time_now(…) return a 64-bit +floating-point value; the number of seconds since vpp started. + +Please see `this Wikipedia +article <https://en.wikipedia.org/wiki/Double-precision_floating-point_format>`__ +for more information. C double-precision floating point numbers (called +f64 in the vpp code base) have a 53-bit effective mantissa, and can +accurately represent 15 decimal digits’ worth of precision. + +There are 315,360,000.000001 seconds in ten years plus one microsecond. +That string has exactly 15 decimal digits. The vpp time base retains 1us +precision for roughly 30 years. + +vlib/clib_time_now do *not* provide precision in excess of 1e-6 seconds. +If necessary, please use clib_cpu_time_now(…) for direct access to the +CPU clock-cycle counter. Note that the number of CPU clock cycles per +second varies significantly across CPU architectures. + +Timer Wheels +------------ + +Vppinfra includes configurable timer wheel support. See the source code +in …/src/vppinfra/tw_timer_template.[ch], as well as a considerable +number of template instances defined in …/src/vppinfra/tw_timer\_.[ch]. + +Instantiation of tw_timer_template.h generates named structures to +implement specific timer wheel geometries. Choices include: number of +timer wheels (currently, 1 or 2), number of slots per ring (a power of +two), and the number of timers per “object handle”. + +Internally, user object/timer handles are 32-bit integers, so if one +selects 16 timers/object (4 bits), the resulting timer wheel handle is +limited to 2**28 objects. + +Here are the specific settings required to generate a single 2048 slot +wheel which supports 2 timers per object: + +.. code:: c + + #define TW_TIMER_WHEELS 1 + #define TW_SLOTS_PER_RING 2048 + #define TW_RING_SHIFT 11 + #define TW_RING_MASK (TW_SLOTS_PER_RING -1) + #define TW_TIMERS_PER_OBJECT 2 + #define LOG2_TW_TIMERS_PER_OBJECT 1 + #define TW_SUFFIX _2t_1w_2048sl + #define TW_FAST_WHEEL_BITMAP 0 + #define TW_TIMER_ALLOW_DUPLICATE_STOP 0 + +See tw_timer_2t_1w_2048sl.h for a complete example. + +tw_timer_template.h is not intended to be #included directly. Client +codes can include multiple timer geometry header files, although extreme +caution would required to use the TW and TWT macros in such a case. + +API usage examples +~~~~~~~~~~~~~~~~~~ + +The unit test code in …/src/vppinfra/test_tw_timer.c provides a concrete +API usage example. It uses a synthetic clock to rapidly exercise the +underlying tw_timer_expire_timers(…) template. + +There are not many API routines to call. + +Initialize a two-timer, single 2048-slot wheel w/ a 1-second timer granularity +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +.. code:: c + + tw_timer_wheel_init_2t_1w_2048sl (&tm->single_wheel, + expired_timer_single_callback, + 1.0 / * timer interval * / ); + +Start a timer +^^^^^^^^^^^^^ + +.. code:: c + + handle = tw_timer_start_2t_1w_2048sl (&tm->single_wheel, elt_index, + [0 | 1] / * timer id * / , + expiration_time_in_u32_ticks); + +Stop a timer +^^^^^^^^^^^^ + +.. code:: c + + tw_timer_stop_2t_1w_2048sl (&tm->single_wheel, handle); + +An expired timer callback +^^^^^^^^^^^^^^^^^^^^^^^^^ + +.. code:: c + + static void + expired_timer_single_callback (u32 * expired_timers) + { + int i; + u32 pool_index, timer_id; + tw_timer_test_elt_t *e; + tw_timer_test_main_t *tm = &tw_timer_test_main; + + for (i = 0; i < vec_len (expired_timers); + { + pool_index = expired_timers[i] & 0x7FFFFFFF; + timer_id = expired_timers[i] >> 31; + + ASSERT (timer_id == 1); + + e = pool_elt_at_index (tm->test_elts, pool_index); + + if (e->expected_to_expire != tm->single_wheel.current_tick) + { + fformat (stdout, "[%d] expired at %d not %d\n", + e - tm->test_elts, tm->single_wheel.current_tick, + e->expected_to_expire); + } + pool_put (tm->test_elts, e); + } + } + +We use wheel timers extensively in the vpp host stack. Each TCP session +needs 5 timers, so supporting 10 million flows requires up to 50 million +concurrent timers. + +Timers rarely expire, so it’s of utmost important that stopping and +restarting a timer costs as few clock cycles as possible. + +Stopping a timer costs a doubly-linked list dequeue. Starting a timer +involves modular arithmetic to determine the correct timer wheel and +slot, and a list head enqueue. + +Expired timer processing generally involves bulk link-list retirement +with user callback presentation. Some additional complexity at wheel +wrap time, to relocate timers from slower-turning timer wheels into +faster-turning wheels. + +Format +------ + +Vppinfra format is roughly equivalent to printf. + +Format has a few properties worth mentioning. Format’s first argument is +a (u8 \*) vector to which it appends the result of the current format +operation. Chaining calls is very easy: + +.. code:: c + + u8 * result; + + result = format (0, "junk = %d, ", junk); + result = format (result, "more junk = %d\n", more_junk); + +As previously noted, NULL pointers are perfectly proper 0-length +vectors. Format returns a (u8 \*) vector, **not** a C-string. If you +wish to print a (u8 \*) vector, use the “%v” format string. If you need +a (u8 \*) vector which is also a proper C-string, either of these +schemes may be used: + +.. code:: c + + vec_add1 (result, 0) + or + result = format (result, "<whatever>%c", 0); + +Remember to vec_free() the result if appropriate. Be careful not to pass +format an uninitialized (u8 \*). + +Format implements a particularly handy user-format scheme via the “%U” +format specification. For example: + +.. code:: c + + u8 * format_junk (u8 * s, va_list *va) + { + junk = va_arg (va, u32); + s = format (s, "%s", junk); + return s; + } + + result = format (0, "junk = %U, format_junk, "This is some junk"); + +format_junk() can invoke other user-format functions if desired. The +programmer shoulders responsibility for argument type-checking. It is +typical for user format functions to blow up spectacularly if the +va_arg(va, type) macros don’t match the caller’s idea of reality. + +Unformat +-------- + +Vppinfra unformat is vaguely related to scanf, but considerably more +general. + +A typical use case involves initializing an unformat_input_t from either +a C-string or a (u8 \*) vector, then parsing via unformat() as follows: + +.. code:: c + + unformat_input_t input; + u8 *s = "<some-C-string>"; + + unformat_init_string (&input, (char *) s, strlen((char *) s)); + /* or */ + unformat_init_vector (&input, <u8-vector>); + +Then loop parsing individual elements: + +.. code:: c + + while (unformat_check_input (&input) != UNFORMAT_END_OF_INPUT) + { + if (unformat (&input, "value1 %d", &value1)) + ;/* unformat sets value1 */ + else if (unformat (&input, "value2 %d", &value2) + ;/* unformat sets value2 */ + else + return clib_error_return (0, "unknown input '%U'", + format_unformat_error, input); + } + +As with format, unformat implements a user-unformat function capability +via a “%U” user unformat function scheme. Generally, one can trivially +transform “format (s,”foo %d”, foo) -> “unformat (input,”foo %d”, +&foo)“. + +Unformat implements a couple of handy non-scanf-like format specifiers: + +.. code:: c + + unformat (input, "enable %=", &enable, 1 /* defaults to 1 */); + unformat (input, "bitzero %|", &mask, (1<<0)); + unformat (input, "bitone %|", &mask, (1<<1)); + <etc> + +The phrase “enable %=” means “set the supplied variable to the default +value” if unformat parses the “enable” keyword all by itself. If +unformat parses “enable 123” set the supplied variable to 123. + +We could clean up a number of hand-rolled “verbose” + “verbose %d” +argument parsing codes using “%=”. + +The phrase “bitzero %\|” means “set the specified bit in the supplied +bitmask” if unformat parses “bitzero”. Although it looks like it could +be fairly handy, it’s very lightly used in the code base. + +``%_`` toggles whether or not to skip input white space. + +For transition from skip to no-skip in middle of format string, skip +input white space. For example, the following: + +.. code:: c + + fmt = "%_%d.%d%_->%_%d.%d%_" + unformat (input, fmt, &one, &two, &three, &four); + +matches input “1.2 -> 3.4”. Without this, the space after -> does not +get skipped. + + +How to parse a single input line +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Debug CLI command functions MUST NOT accidentally consume input +belonging to other debug CLI commands. Otherwise, it's impossible to +script a set of debug CLI commands which "work fine" when issued one +at a time. + +This bit of code is NOT correct: + +.. code:: c + + /* Eats script input NOT beloging to it, and chokes! */ + while (unformat_check_input (input) != UNFORMAT_END_OF_INPUT) + { + if (unformat (input, ...)) + ; + else if (unformat (input, ...)) + ; + else + return clib_error_return (0, "parse error: '%U'", + format_unformat_error, input); + } + } + +When executed as part of a script, such a function will return “parse +error: ‘’” every time, unless it happens to be the last command in the +script. + +Instead, use “unformat_line_input” to consume the rest of a line’s worth +of input - everything past the path specified in the VLIB_CLI_COMMAND +declaration. + +For example, unformat_line_input with “my_command” set up as shown below +and user input “my path is clear” will produce an unformat_input_t that +contains “is clear”. + +.. code:: c + + VLIB_CLI_COMMAND (...) = { + .path = "my path", + }; + +Here’s a bit of code which shows the required mechanics, in full: + +.. code:: c + + static clib_error_t * + my_command_fn (vlib_main_t * vm, + unformat_input_t * input, + vlib_cli_command_t * cmd) + { + unformat_input_t _line_input, *line_input = &_line_input; + u32 this, that; + clib_error_t *error = 0; + + if (!unformat_user (input, unformat_line_input, line_input)) + return 0; + + /* + * Here, UNFORMAT_END_OF_INPUT is at the end of the line we consumed, + * not at the end of the script... + */ + while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) + { + if (unformat (line_input, "this %u", &this)) + ; + else if (unformat (line_input, "that %u", &that)) + ; + else + { + error = clib_error_return (0, "parse error: '%U'", + format_unformat_error, line_input); + goto done; + } + } + + <do something based on "this" and "that", etc> + + done: + unformat_free (line_input); + return error; + } + VLIB_CLI_COMMAND (my_command, static) = { + .path = "my path", + .function = my_command_fn", + }; + +Vppinfra errors and warnings +---------------------------- + +Many functions within the vpp dataplane have return-values of type +clib_error_t \*. Clib_error_t’s are arbitrary strings with a bit of +metadata [fatal, warning] and are easy to announce. Returning a NULL +clib_error_t \* indicates “A-OK, no error.” + +Clib_warning(format-args) is a handy way to add debugging output; clib +warnings prepend function:line info to unambiguously locate the message +source. Clib_unix_warning() adds perror()-style Linux system-call +information. In production images, clib_warnings result in syslog +entries. + +Serialization +------------- + +Vppinfra serialization support allows the programmer to easily serialize +and unserialize complex data structures. + +The underlying primitive serialize/unserialize functions use network +byte-order, so there are no structural issues serializing on a +little-endian host and unserializing on a big-endian host. diff --git a/docs/developer/corearchitecture/mem.rst b/docs/developer/corearchitecture/mem.rst new file mode 120000 index 00000000000..0fc53eab68c --- /dev/null +++ b/docs/developer/corearchitecture/mem.rst @@ -0,0 +1 @@ +../../../src/vpp/mem/mem.rst

Automatic +placement works in the following way: + +- if “skip-cores X” is defined first X cores will not be used +- if “main-core X” is defined, VPP main thread will be placed on core + X, otherwise 1st available one will be used +- if “workers N” is defined vpp will allocate first N available cores + and it will run threads on them +- if “corelist-workers A,B1-Bn,C1-Cn” is defined vpp will automatically + assign those CPU cores to worker threads + +User can see active placement of cores by using the VPP debug CLI +command show threads: + +.. code-block:: console + + vpd# show threads + ID Name Type LWP lcore Core Socket State + 0 vpe_main 59723 2 2 0 wait + 1 vpe_wk_0 workers 59755 4 4 0 running + 2 vpe_wk_1 workers 59756 5 5 0 running + 3 vpe_wk_2 workers 59757 6 0 1 running + 4 vpe_wk_3 workers 59758 7 1 1 running + 5 stats 59775 + vpd# + +The sample output above shows the main thread running on core 2 (2nd +core on the CPU socket 0), worker threads running on cores 4-7. + +Sample Configurations +--------------------- + +By default, at start-up VPP uses +configuration values from: ``/etc/vpp/startup.conf`` + +The following sections describe some of the additional changes that can be made to this file. +This file is initially populated from the files located in the following directory ``/vpp/vpp/conf/`` + +Manual Placement +~~~~~~~~~~~~~~~~ + +Manual placement places the main thread on core 1, workers on cores +4,5,20,21. + +.. code-block:: console + + cpu { + main-core 1 + corelist-workers 4-5,20-21 + } + +Auto placement +-------------- + +Auto placement is likely to place the main thread on core 1 and workers +on cores 2,3,4. + +.. code-block:: console + + cpu { + skip-cores 1 + workers 3 + } + +Buffer Memory Allocation +~~~~~~~~~~~~~~~~~~~~~~~~ + +The VPP platform is NUMA aware. It can allocate memory for buffers on +different CPU sockets (NUMA nodes).

Each worker thread uses buffers which are local to itself. + +Buffer memory is allocated from hugepages. VPP prefers 1G pages if they +are available. If not 2MB pages will be used. + +VPP takes care of mounting/unmounting hugepages file-system +automatically so there is no need to do that manually. + +’‘’NOTE’’’: If you are running latest VPP release, there is no need for +specifying socket-mem manually. VPP will discover all NUMA nodes and it +will allocate 512M on each by default. socket-mem is only needed if +bigger number of mbufs is required (default is 16384 per socket and can +be changed with num-mbufs startup config command). + +Interface Placement in Multi-thread Setup +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +On startup, the VPP platform assigns interfaces (or interface, queue +pairs if RSS is used) to different worker threads in round robin +fashion. + +The following example shows debug CLI commands to show and change +interface placement: + +.. code-block:: console + + vpd# sh dpdk interface placement + Thread 1 (vpp_wk_0 at lcore 5): + TenGigabitEthernet2/0/0 queue 0 + TenGigabitEthernet2/0/1 queue 0 + Thread 2 (vpp_wk_1 at lcore 6): + TenGigabitEthernet2/0/0 queue 1 + TenGigabitEthernet2/0/1 queue 1 + +The following shows an example of moving TenGigabitEthernet2/0/1 queue 1 +processing to 1st worker thread: + +.. code-block:: console + + vpd# set interface placement TenGigabitEthernet2/0/1 queue 1 thread 1 + + vpp# sh dpdk interface placement + Thread 1 (vpp_wk_0 at lcore 5): + TenGigabitEthernet2/0/0 queue 0 + TenGigabitEthernet2/0/1 queue 0 + TenGigabitEthernet2/0/1 queue 1 + Thread 2 (vpp_wk_1 at lcore 6): + TenGigabitEthernet2/0/0 queue 1 diff --git a/docs/gettingstarted/developers/multiarch/arbfns.rst b/docs/developer/corearchitecture/multiarch/arbfns.rst index d469bd8a140..d469bd8a140 100644 --- a/docs/gettingstarted/developers/multiarch/arbfns.rst +++ b/docs/developer/corearchitecture/multiarch/arbfns.rst diff --git a/docs/gettingstarted/developers/multiarch/index.rst b/docs/developer/corearchitecture/multiarch/index.rst index 824a8e68438..824a8e68438 100644 --- a/docs/gettingstarted/developers/multiarch/index.rst +++ b/docs/developer/corearchitecture/multiarch/index.rst diff --git a/docs/gettingstarted/developers/multiarch/nodefns.rst b/docs/developer/corearchitecture/multiarch/nodefns.rst index a43d40e301f..9647e64f08c 100644 --- a/docs/gettingstarted/developers/multiarch/nodefns.rst +++ b/docs/developer/corearchitecture/multiarch/nodefns.rst @@ -23,9 +23,9 @@ Details ------- Declare the node dispatch function as shown, using the VLIB\_NODE\_FN macro.

At runtime, the framework processes the set of +such registrations into a directed graph. It is easy enough to add nodes +to the graph at runtime. The framework does not support removing nodes. + +vlib provides several types of vector-processing graph nodes, primarily +to control framework dispatch behaviors. The type member of the +vlib_node_registration_t functions as follows: + +- VLIB_NODE_TYPE_PRE_INPUT - run before all other node types +- VLIB_NODE_TYPE_INPUT - run as often as possible, after pre_input + nodes +- VLIB_NODE_TYPE_INTERNAL - only when explicitly made runnable by + adding pending frames for processing +- VLIB_NODE_TYPE_PROCESS - only when explicitly made runnable. + “Process” nodes are actually cooperative multi-tasking threads. They + **must** explicitly suspend after a reasonably short period of time. + +For a precise understanding of the graph node dispatcher, please read +./src/vlib/main.c:vlib_main_loop. + +Graph node dispatcher +--------------------- + +Vlib_main_loop() dispatches graph nodes. The basic vector processing +algorithm is diabolically simple, but may not be obvious from even a +long stare at the code. Here’s how it works: some input node, or set of +input nodes, produce a vector of work to process. The graph node +dispatcher pushes the work vector through the directed graph, +subdividing it as needed, until the original work vector has been +completely processed. At that point, the process recurs. + +This scheme yields a stable equilibrium in frame size, by construction. +Here’s why: as the frame size increases, the per-frame-element +processing time decreases. There are several related forces at work; the +simplest to describe is the effect of vector processing on the CPU L1 +I-cache. The first frame element [packet] processed by a given node +warms up the node dispatch function in the L1 I-cache. All subsequent +frame elements profit. As we increase the number of frame elements, the +cost per element goes down. + +Under light load, it is a crazy waste of CPU cycles to run the graph +node dispatcher flat-out. So, the graph node dispatcher arranges to wait +for work by sitting in a timed epoll wait if the prevailing frame size +is low. The scheme has a certain amount of hysteresis to avoid +constantly toggling back and forth between interrupt and polling mode. +Although the graph dispatcher supports interrupt and polling modes, our +current default device drivers do not. + +The graph node scheduler uses a hierarchical timer wheel to reschedule +process nodes upon timer expiration. + +Graph dispatcher internals +-------------------------- + +This section may be safely skipped. It’s not necessary to understand +graph dispatcher internals to create graph nodes. + +Vector Data Structure +--------------------- + +In vpp / vlib, we represent vectors as instances of the vlib_frame_t +type: + +.. code:: c + + typedef struct vlib_frame_t + { + /* Frame flags. */ + u16 flags; + + /* Number of scalar bytes in arguments. */ + u8 scalar_size; + + /* Number of bytes per vector argument. */ + u8 vector_size; + + /* Number of vector elements currently in frame. */ + u16 n_vectors; + + /* Scalar and vector arguments to next node. */ + u8 arguments[0]; + } vlib_frame_t; + +Note that one *could* construct all kinds of vectors - including vectors +with some associated scalar data - using this structure. In the vpp +application, vectors typically use a 4-byte vector element size, and +zero bytes’ worth of associated per-frame scalar data. + +Frames are always allocated on CLIB_CACHE_LINE_BYTES boundaries. Frames +have u32 indices which make use of the alignment property, so the +maximum feasible main heap offset of a frame is CLIB_CACHE_LINE_BYTES \* +0xFFFFFFFF: 64*4 = 256 Gbytes. + +Scheduling Vectors +------------------ + +As you can see, vectors are not directly associated with graph nodes. We +represent that association in a couple of ways. The simplest is the +vlib_pending_frame_t: + +.. code:: c + + /* A frame pending dispatch by main loop. */ + typedef struct + { + /* Node and runtime for this frame. */ + u32 node_runtime_index; + + /* Frame index (in the heap). */ + u32 frame_index; + + /* Start of next frames for this node. */ + u32 next_frame_index; + + /* Special value for next_frame_index when there is no next frame. */ + #define VLIB_PENDING_FRAME_NO_NEXT_FRAME ((u32) ~0) + } vlib_pending_frame_t; + +Here is the code in …/src/vlib/main.c:vlib_main_or_worker_loop() which +processes frames: + +.. code:: c + + /* + * Input nodes may have added work to the pending vector. + * Process pending vector until there is nothing left. + * All pending vectors will be processed from input -> output. + */ + for (i = 0; i < _vec_len (nm->pending_frames); i++) + cpu_time_now = dispatch_pending_node (vm, i, cpu_time_now); + /* Reset pending vector for next iteration. */ + +The pending frame node_runtime_index associates the frame with the node +which will process it. + +Complications +------------- + +Fasten your seatbelt. Here’s where the story - and the data structures - +become quite complicated… + +At 100,000 feet: vpp uses a directed graph, not a directed *acyclic* +graph. It’s really quite normal for a packet to visit ip[46]-lookup +multiple times. The worst-case: a graph node which enqueues packets to +itself. + +To deal with this issue, the graph dispatcher must force allocation of a +new frame if the current graph node’s dispatch function happens to +enqueue a packet back to itself. + +There are no guarantees that a pending frame will be processed +immediately, which means that more packets may be added to the +underlying vlib_frame_t after it has been attached to a +vlib_pending_frame_t. Care must be taken to allocate new frames and +pending frames if a (pending_frame, frame) pair fills. + +Next frames, next frame ownership +--------------------------------- + +The vlib_next_frame_t is the last key graph dispatcher data structure: + +.. code:: c + + typedef struct + { + /* Frame index. */ + u32 frame_index; + + /* Node runtime for this next. */ + u32 node_runtime_index; + + /* Next frame flags. */ + u32 flags; + + /* Reflects node frame-used flag for this next. */ + #define VLIB_FRAME_NO_FREE_AFTER_DISPATCH \ + VLIB_NODE_FLAG_FRAME_NO_FREE_AFTER_DISPATCH + + /* This next frame owns enqueue to node + corresponding to node_runtime_index. */ + #define VLIB_FRAME_OWNER (1 << 15) + + /* Set when frame has been allocated for this next. */ + #define VLIB_FRAME_IS_ALLOCATED VLIB_NODE_FLAG_IS_OUTPUT + + /* Set when frame has been added to pending vector. */ + #define VLIB_FRAME_PENDING VLIB_NODE_FLAG_IS_DROP + + /* Set when frame is to be freed after dispatch. */ + #define VLIB_FRAME_FREE_AFTER_DISPATCH VLIB_NODE_FLAG_IS_PUNT + + /* Set when frame has traced packets. */ + #define VLIB_FRAME_TRACE VLIB_NODE_FLAG_TRACE + + /* Number of vectors enqueue to this next since last overflow. */ + u32 vectors_since_last_overflow; + } vlib_next_frame_t; + +Graph node dispatch functions call vlib_get_next_frame (…) to set “(u32 +\*)to_next” to the right place in the vlib_frame_t corresponding to the +ith arc (aka next0) from the current node to the indicated next node. + +After some scuffling around - two levels of macros - processing reaches +vlib_get_next_frame_internal (…). Get-next-frame-internal digs up the +vlib_next_frame_t corresponding to the desired graph arc. + +The next frame data structure amounts to a graph-arc-centric frame +cache. Once a node finishes adding element to a frame, it will acquire a +vlib_pending_frame_t and end up on the graph dispatcher’s run-queue. But +there’s no guarantee that more vector elements won’t be added to the +underlying frame from the same (source_node, next_index) arc or from a +different (source_node, next_index) arc. + +Maintaining consistency of the arc-to-frame cache is necessary. The +first step in maintaining consistency is to make sure that only one +graph node at a time thinks it “owns” the target vlib_frame_t. + +Back to the graph node dispatch function. In the usual case, a certain +number of packets will be added to the vlib_frame_t acquired by calling +vlib_get_next_frame (…). + +Before a dispatch function returns, it’s required to call +vlib_put_next_frame (…) for all of the graph arcs it actually used. This +action adds a vlib_pending_frame_t to the graph dispatcher’s pending +frame vector. + +Vlib_put_next_frame makes a note in the pending frame of the frame +index, and also of the vlib_next_frame_t index. + +dispatch_pending_node actions +----------------------------- + +The main graph dispatch loop calls dispatch pending node as shown above. + +Dispatch_pending_node recovers the pending frame, and the graph node +runtime / dispatch function. Further, it recovers the next_frame +currently associated with the vlib_frame_t, and detaches the +vlib_frame_t from the next_frame. + +In …/src/vlib/main.c:dispatch_pending_node(…), note this stanza: + +.. code:: c + + /* Force allocation of new frame while current frame is being + dispatched. */ + restore_frame_index = ~0; + if (nf->frame_index == p->frame_index) + { + nf->frame_index = ~0; + nf->flags &= ~VLIB_FRAME_IS_ALLOCATED; + if (!(n->flags & VLIB_NODE_FLAG_FRAME_NO_FREE_AFTER_DISPATCH)) + restore_frame_index = p->frame_index; + } + +dispatch_pending_node is worth a hard stare due to the several +second-order optimizations it implements. Almost as an afterthought, it +calls dispatch_node which actually calls the graph node dispatch +function. + +Process / thread model +---------------------- + +vlib provides an ultra-lightweight cooperative multi-tasking thread +model. The graph node scheduler invokes these processes in much the same +way as traditional vector-processing run-to-completion graph nodes; +plus-or-minus a setjmp/longjmp pair required to switch stacks. Simply +set the vlib_node_registration_t type field to vlib_NODE_TYPE_PROCESS. +Yes, process is a misnomer. These are cooperative multi-tasking threads. + +As of this writing, the default stack size is 2<<15 = 32kb. Initialize +the node registration’s process_log2_n_stack_bytes member as needed. The +graph node dispatcher makes some effort to detect stack overrun, e.g. by +mapping a no-access page below each thread stack. + +Process node dispatch functions are expected to be “while(1) { }” loops +which suspend when not otherwise occupied, and which must not run for +unreasonably long periods of time. + +“Unreasonably long” is an application-dependent concept. Over the years, +we have constructed frame-size sensitive control-plane nodes which will +use a much higher fraction of the available CPU bandwidth when the frame +size is low. The classic example: modifying forwarding tables. So long +as the table-builder leaves the forwarding tables in a valid state, one +can suspend the table builder to avoid dropping packets as a result of +control-plane activity. + +Process nodes can suspend for fixed amounts of time, or until another +entity signals an event, or both. See the next section for a description +of the vlib process event mechanism. + +When running in vlib process context, one must pay strict attention to +loop invariant issues. If one walks a data structure and calls a +function which may suspend, one had best know by construction that it +cannot change. Often, it’s best to simply make a snapshot copy of a data +structure, walk the copy at leisure, then free the copy. + +Process events +-------------- + +The vlib process event mechanism API is extremely lightweight and easy +to use. Here is a typical example: + +.. code:: c + + vlib_main_t *vm = &vlib_global_main; + uword event_type, * event_data = 0; + + while (1) + { + vlib_process_wait_for_event_or_clock (vm, 5.0 /* seconds */); + + event_type = vlib_process_get_events (vm, &event_data); + + switch (event_type) { + case EVENT1: + handle_event1s (event_data); + break; + + case EVENT2: + handle_event2s (event_data); + break; + + case ~0: /* 5-second idle/periodic */ + handle_idle (); + break; + + default: /* bug! */ + ASSERT (0); + } + + vec_reset_length(event_data); + } + +In this example, the VLIB process node waits for an event to occur, or +for 5 seconds to elapse. The code demuxes on the event type, calling the +appropriate handler function. Each call to vlib_process_get_events +returns a vector of per-event-type data passed to successive +vlib_process_signal_event calls; it is a serious error to process only +event_data[0]. + +Resetting the event_data vector-length to 0 [instead of calling +vec_free] means that the event scheme doesn’t burn cycles continuously +allocating and freeing the event data vector. This is a common vppinfra +/ vlib coding pattern, well worth using when appropriate. + +Signaling an event is easy, for example: + +.. code:: c + + vlib_process_signal_event (vm, process_node_index, EVENT1, + (uword)arbitrary_event1_data); /* and so forth */ + +One can either know the process node index by construction - dig it out +of the appropriate vlib_node_registration_t - or by finding the +vlib_node_t with vlib_get_node_by_name(…). + +Buffers +------- + +vlib buffering solves the usual set of packet-processing problems, +albeit at high performance. Key in terms of performance: one ordinarily +allocates / frees N buffers at a time rather than one at a time. Except +when operating directly on a specific buffer, one deals with buffers by +index, not by pointer. + +Packet-processing frames are u32[] arrays, not vlib_buffer_t[] arrays. + +Packets comprise one or more vlib buffers, chained together as required. +Multiple particle sizes are supported; hardware input nodes simply ask +for the required size(s). Coalescing support is available. For obvious +reasons one is discouraged from writing one’s own wild and wacky buffer +chain traversal code. + +vlib buffer headers are allocated immediately prior to the buffer data +area. In typical packet processing this saves a dependent read wait: +given a buffer’s address, one can prefetch the buffer header [metadata] +at the same time as the first cache line of buffer data. + +Buffer header metadata (vlib_buffer_t) includes the usual rewrite +expansion space, a current_data offset, RX and TX interface indices, +packet trace information, and a opaque areas. + +The opaque data is intended to control packet processing in arbitrary +subgraph-dependent ways. The programmer shoulders responsibility for +data lifetime analysis, type-checking, etc. + +Buffers have reference-counts in support of e.g. multicast replication. + +Shared-memory message API +------------------------- + +Local control-plane and application processes interact with the vpp +dataplane via asynchronous message-passing in shared memory over +unidirectional queues. The same application APIs are available via +sockets. + +Capturing API traces and replaying them in a simulation environment +requires a disciplined approach to the problem. This seems like a +make-work task, but it is not. When something goes wrong in the +control-plane after 300,000 or 3,000,000 operations, high-speed replay +of the events leading up to the accident is a huge win. + +The shared-memory message API message allocator vl_api_msg_alloc uses a +particularly cute trick. Since messages are processed in order, we try +to allocate message buffering from a set of fixed-size, preallocated +rings. Each ring item has a “busy” bit. Freeing one of the preallocated +message buffers merely requires the message consumer to clear the busy +bit. No locking required. + +Debug CLI +--------- + +Adding debug CLI commands to VLIB applications is very simple. + +Here is a complete example: + +.. code:: c + + static clib_error_t * + show_ip_tuple_match (vlib_main_t * vm, + unformat_input_t * input, + vlib_cli_command_t * cmd) + { + vlib_cli_output (vm, "%U\n", format_ip_tuple_match_tables, &routing_main); + return 0; + } + + static VLIB_CLI_COMMAND (show_ip_tuple_command) = + { + .path = "show ip tuple match", + .short_help = "Show ip 5-tuple match-and-broadcast tables", + .function = show_ip_tuple_match, + }; + +This example implements the “show ip tuple match” debug cli command. In +ordinary usage, the vlib cli is available via the “vppctl” application, +which sends traffic to a named pipe. One can configure debug CLI telnet +access on a configurable port. + +The cli implementation has an output redirection facility which makes it +simple to deliver cli output via shared-memory API messaging, + +Particularly for debug or “show tech support” type commands, it would be +wasteful to write vlib application code to pack binary data, write more +code elsewhere to unpack the data and finally print the answer. If a +certain cli command has the potential to hurt packet processing +performance by running for too long, do the work incrementally in a +process node. The client can wait. + +Macro expansion +~~~~~~~~~~~~~~~ + +The vpp debug CLI engine includes a recursive macro expander. This is +quite useful for factoring out address and/or interface name specifics: + +:: + + define ip1 192.168.1.1/24 + define ip2 192.168.2.1/24 + define iface1 GigabitEthernet3/0/0 + define iface2 loop1 + + set int ip address $iface1 $ip1 + set int ip address $iface2 $(ip2) + + undefine ip1 + undefine ip2 + undefine iface1 + undefine iface2 + +Each socket (or telnet) debug CLI session has its own macro tables. All +debug CLI sessions which use CLI_INBAND binary API messages share a +single table. + +The macro expander recognizes circular definitions: + +:: + + define foo \$(bar) + define bar \$(mumble) + define mumble \$(foo) + +At 8 levels of recursion, the macro expander throws up its hands and +replies “CIRCULAR.” + +Macro-related debug CLI commands +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +In addition to the “define” and “undefine” debug CLI commands, use “show +macro [noevaluate]” to dump the macro table. The “echo” debug CLI +command will evaluate and print its argument: + +:: + + vpp# define foo This\ Is\ Foo + vpp# echo $foo + This Is Foo + +Handing off buffers between threads +----------------------------------- + +Vlib includes an easy-to-use mechanism for handing off buffers between +worker threads. A typical use-case: software ingress flow hashing. At a +high level, one creates a per-worker-thread queue which sends packets to +a specific graph node in the indicated worker thread. With the queue in +hand, enqueue packets to the worker thread of your choice. + +Initialize a handoff queue +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Simple enough, call vlib_frame_queue_main_init: + +.. code:: c + + main_ptr->frame_queue_index + = vlib_frame_queue_main_init (dest_node.index, frame_queue_size); + +Frame_queue_size means what it says: the number of frames which may be +queued. Since frames contain 1…256 packets, frame_queue_size should be a +reasonably small number (32…64). If the frame queue producer(s) are +faster than the frame queue consumer(s), congestion will occur. Suggest +letting the enqueue operator deal with queue congestion, as shown in the +enqueue example below. + +Under the floorboards, vlib_frame_queue_main_init creates an input queue +for each worker thread. + +Please do NOT create frame queues until it’s clear that they will be +used. Although the main dispatch loop is reasonably smart about how +often it polls the (entire set of) frame queues, polling unused frame +queues is a waste of clock cycles. + +Hand off packets +~~~~~~~~~~~~~~~~ + +The actual handoff mechanics are simple, and integrate nicely with a +typical graph-node dispatch function: + +.. code:: c + + always_inline uword + do_handoff_inline (vlib_main_t * vm, + vlib_node_runtime_t * node, vlib_frame_t * frame, + int is_ip4, int is_trace) + { + u32 n_left_from, *from; + vlib_buffer_t *bufs[VLIB_FRAME_SIZE], **b; + u16 thread_indices [VLIB_FRAME_SIZE]; + u16 nexts[VLIB_FRAME_SIZE], *next; + u32 n_enq; + htest_main_t *hmp = &htest_main; + int i; + + from = vlib_frame_vector_args (frame); + n_left_from = frame->n_vectors; + + vlib_get_buffers (vm, from, bufs, n_left_from); + next = nexts; + b = bufs; + + /* + * Typical frame traversal loop, details vary with + * use case.

The Network Stack Layer is basically an +instantiation of the code in the other layers. This layer has a vnet +library that provides vectorized layer-2 and 3 networking graph nodes, a +packet generator, and a packet tracer. + +In terms of building a packet processing application, vnet provides a +platform-independent subgraph to which one connects a couple of +device-driver nodes. + +Typical RX connections include “ethernet-input” [full software +classification, feeds ipv4-input, ipv6-input, arp-input etc.] and +“ipv4-input-no-checksum” [if hardware can classify, perform ipv4 header +checksum]. + +Effective graph dispatch function coding +---------------------------------------- + +Over the 15 years, multiple coding styles have emerged: a +single/dual/quad loop coding model (with variations) and a +fully-pipelined coding model. + +Single/dual loops +----------------- + +The single/dual/quad loop model variations conveniently solve problems +where the number of items to process is not known in advance: typical +hardware RX-ring processing.

Its not difficult, but accurate buffer metadata setup is required. + +Allocating Buffers +~~~~~~~~~~~~~~~~~~ + +Use vlib_buffer_alloc, which allocates a set of buffer indices.

That’s +typical in case you need to send one packet per second, but should +**not** occur in a for-loop! + +Packet tracer +------------- + +Vlib includes a frame element [packet] trace facility, with a simple +debug CLI interface. The cli is straightforward: “trace add +input-node-name count” to start capturing packet traces. + +To trace 100 packets on a typical x86_64 system running the dpdk plugin: +“trace add dpdk-input 100”. When using the packet generator: “trace add +pg-input 100” + +To display the packet trace: “show trace” + +Each graph node has the opportunity to capture its own trace data. It is +almost always a good idea to do so. The trace capture APIs are simple. + +The packet capture APIs snapshoot binary data, to minimize processing at +capture time. Each participating graph node initialization provides a +vppinfra format-style user function to pretty-print data when required +by the VLIB “show trace” command. + +Set the VLIB node registration “.format_trace” member to the name of the +per-graph node format function. + +Here’s a simple example: + +.. code:: c + + u8 * my_node_format_trace (u8 * s, va_list * args) + { + vlib_main_t * vm = va_arg (*args, vlib_main_t *); + vlib_node_t * node = va_arg (*args, vlib_node_t *); + my_node_trace_t * t = va_arg (*args, my_trace_t *); + + s = format (s, "My trace data was: %d", t-><whatever>); + + return s; + } + +The trace framework hands the per-node format function the data it +captured as the packet whizzed by.

Each of “pcap trace rx”, “pcap trace tx”, and +“pcap trace drop” is implemented. Supply one or more of “rx”, “tx”, and +“drop” to enable multiple simultaneous capture types. + +These commands have the following optional parameters: + +- rx - trace received packets. + +- tx - trace transmitted packets. + +- drop - trace dropped packets. + +- max *nnnn*\ - file size, number of packet captures. Once packets + have been received, the trace buffer buffer is flushed to the + indicated file. Defaults to 1000. Can only be updated if packet + capture is off. + +- max-bytes-per-pkt *nnnn*\ - maximum number of bytes to trace on a + per-packet basis. Must be >32 and less than 9000. Default value: + + 512. + +- filter - Use the pcap rx / tx / drop trace filter, which must be + configured. Use classify filter pcap… to configure the filter. The + filter will only be executed if the per-interface or any-interface + tests fail. + +- intfc *interface* \| *any*\ - Used to specify a given interface, or + use ‘any’ to run packet capture on all interfaces. ‘any’ is the + default if not provided. Settings from a previous packet capture are + preserved, so ‘any’ can be used to reset the interface setting. + +- file *filename*\ - Used to specify the output filename. The file + will be placed in the ‘/tmp’ directory. If *filename* already exists, + file will be overwritten. If no filename is provided, ‘/tmp/rx.pcap + or tx.pcap’ will be used, depending on capture direction. Can only be + updated when pcap capture is off. + +- status - Displays the current status and configured attributes + associated with a packet capture. If packet capture is in progress, + ‘status’ also will return the number of packets currently in the + buffer. Any additional attributes entered on command line with a + ‘status’ request will be ignored. + +- filter - Capture packets which match the current packet trace filter + set. See next section. Configure the capture filter first. + +packet trace capture filtering +------------------------------ + +The “classify filter pcap \| \| trace” debug CLI command constructs an +arbitrary set of packet classifier tables for use with “pcap rx \| tx \| +drop trace,” and with the vpp packet tracer on a per-interface or +system-wide basis. + +Packets which match a rule in the classifier table chain will be traced. +The tables are automatically ordered so that matches in the most +specific table are tried first. + +It’s reasonably likely that folks will configure a single table with one +or two matches. As a result, we configure 8 hash buckets and 128K of +match rule space by default. One can override the defaults by specifying +“buckets ” and “memory-size ” as desired. + +To build up complex filter chains, repeatedly issue the classify filter +debug CLI command. Each command must specify the desired mask and match +values. If a classifier table with a suitable mask already exists, the +CLI command adds a match rule to the existing table. If not, the CLI +command add a new table and the indicated mask rule + +Configure a simple pcap classify filter +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + classify filter pcap mask l3 ip4 src match l3 ip4 src 192.168.1.11 + pcap trace rx max 100 filter + +Configure a simple per-interface capture filter +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + classify filter GigabitEthernet3/0/0 mask l3 ip4 src match l3 ip4 src 192.168.1.11" + pcap trace rx max 100 intfc GigabitEthernet3/0/0 + +Note that per-interface capture filters are *always* applied. + +Clear per-interface capture filters +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + classify filter GigabitEthernet3/0/0 del + +Configure another fairly simple pcap classify filter +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + classify filter pcap mask l3 ip4 src dst match l3 ip4 src 192.168.1.10 dst 192.168.2.10 + pcap trace tx max 100 filter + +Configure a vpp packet tracer filter +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + classify filter trace mask l3 ip4 src dst match l3 ip4 src 192.168.1.10 dst 192.168.2.10 + trace add dpdk-input 100 filter + +Clear all current classifier filters +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + classify filter [pcap | <interface> | trace] del + +To inspect the classifier tables +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + show classify table [verbose] + +The verbose form displays all of the match rules, with hit-counters. + +Terse description of the “mask ” syntax: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:: + + l2 src dst proto tag1 tag2 ignore-tag1 ignore-tag2 cos1 cos2 dot1q dot1ad + l3 ip4 <ip4-mask> ip6 <ip6-mask> + <ip4-mask> version hdr_length src[/width] dst[/width] + tos length fragment_id ttl protocol checksum + <ip6-mask> version traffic-class flow-label src dst proto + payload_length hop_limit protocol + l4 tcp <tcp-mask> udp <udp_mask> src_port dst_port + <tcp-mask> src dst # ports + <udp-mask> src_port dst_port + +To construct **matches**, add the values to match after the indicated +keywords in the mask syntax. For example: “… mask l3 ip4 src” -> “… +match l3 ip4 src 192.168.1.11” + +VPP Packet Generator +-------------------- + +We use the VPP packet generator to inject packets into the forwarding +graph. The packet generator can replay pcap traces, and generate packets +out of whole cloth at respectably high performance. + +The VPP pg enables quite a variety of use-cases, ranging from functional +testing of new data-plane nodes to regression testing to performance +tuning. + +PG setup scripts +---------------- + +PG setup scripts describe traffic in detail, and leverage vpp debug CLI +mechanisms. It’s reasonably unusual to construct a pg setup script which +doesn’t include a certain amount of interface and FIB configuration. + +For example: + +:: + + loop create + set int ip address loop0 192.168.1.1/24 + set int state loop0 up + + packet-generator new { + name pg0 + limit 100 + rate 1e6 + size 300-300 + interface loop0 + node ethernet-input + data { IP4: 1.2.3 -> 4.5.6 + UDP: 192.168.1.10 - 192.168.1.254 -> 192.168.2.10 + UDP: 1234 -> 2345 + incrementing 286 + } + } + +A packet generator stream definition includes two major sections: - +Stream Parameter Setup - Packet Data + +Stream Parameter Setup +~~~~~~~~~~~~~~~~~~~~~~ + +Given the example above, let’s look at how to set up stream parameters: + +- **name pg0** - Name of the stream, in this case “pg0” + +- **limit 1000** - Number of packets to send when the stream is + enabled. “limit 0” means send packets continuously. + +- **maxframe <nnn>** - Maximum frame size. Handy for injecting multiple + frames no larger than <nnn>. Useful for checking dual / quad loop + codes + +- **rate 1e6** - Packet injection rate, in this case 1 MPPS. When not + specified, the packet generator injects packets as fast as possible + +- **size 300-300** - Packet size range, in this case send 300-byte + packets + +- **interface loop0** - Packets appear as if they were received on the + specified interface. This datum is used in multiple ways: to select + graph arc feature configuration, to select IP FIBs. Configure + features e.g. on loop0 to exercise those features. + +- **tx-interface <name>** - Packets will be transmitted on the + indicated interface. Typically required only when injecting packets + into post-IP-rewrite graph nodes. + +- **pcap <filename>** - Replay packets from the indicated pcap capture + file. “make test” makes extensive use of this feature: generate + packets using scapy, save them in a .pcap file, then inject them into + the vpp graph via a vpp pg “pcap <filename>” stream definition + +- **worker <nn>** - Generate packets for the stream using the indicated + vpp worker thread. The vpp pg generates and injects O(10 MPPS / + core). Use multiple stream definitions and worker threads to generate + and inject enough traffic to easily fill a 40 gbit pipe with small + packets. + +Data definition +~~~~~~~~~~~~~~~ + +Packet generator data definitions make use of a layered implementation +strategy. Networking layers are specified in order, and the notation can +seem a bit counter-intuitive. In the example above, the data definition +stanza constructs a set of L2-L4 headers layers, and uses an +incrementing fill pattern to round out the requested 300-byte packets. + +- **IP4: 1.2.3 -> 4.5.6** - Construct an L2 (MAC) header with the ip4 + ethertype (0x800), src MAC address of 00:01:00:02:00:03 and dst MAC + address of 00:04:00:05:00:06. Mac addresses may be specified in + either *xxxx.xxxx.xxxx* format or *xx:xx:xx:xx:xx:xx* format. + +- **UDP: 192.168.1.10 - 192.168.1.254 -> 192.168.2.10** - Construct an + incrementing set of L3 (IPv4) headers for successive packets with + source addresses ranging from .10 to .254. All packets in the stream + have a constant dest address of 192.168.2.10. Set the protocol field + to 17, UDP. + +- **UDP: 1234 -> 2345** - Set the UDP source and destination ports to + 1234 and 2345, respectively + +- **incrementing 256** - Insert up to 256 incrementing data bytes. + +Obvious variations involve “s/IP4/IP6/” in the above, along with +changing from IPv4 to IPv6 address notation. + +The vpp pg can set any / all IPv4 header fields, including tos, packet +length, mf / df / fragment id and offset, ttl, protocol, checksum, and +src/dst addresses. Take a look at ../src/vnet/ip/ip[46]_pg.c for +details. + +If all else fails, specify the entire packet data in hex: + +- **hex 0xabcd…** - copy hex data verbatim into the packet + +When replaying pcap files (“**pcap <filename>**”), do not specify a data +stanza. + +Diagnosing “packet-generator new” parse failures +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you want to inject packets into a brand-new graph node, remember to +tell the packet generator debug CLI how to parse the packet data stanza. + +If the node expects L2 Ethernet MAC headers, specify “.unformat_buffer = +unformat_ethernet_header”: + +.. code:: c + + VLIB_REGISTER_NODE (ethernet_input_node) = + { + <snip> + .unformat_buffer = unformat_ethernet_header, + <snip> + }; + +Beyond that, it may be necessary to set breakpoints in +…/src/vnet/pg/cli.c.

We use -the least-significant N bits of the hash to select the bucket. - -With the bucket in hand, we learn log2 (nBackingPages) for the -selected bucket. At this point, we use the next log2_size bits from -the hash code to select the specific backing page in which the -(key,value) page will be found. - -Net result: we search **one** backing page, not 2**log2_size -pages. This is a key property of the algorithm. - -When sufficient collisions occur to fill the backing pages for a given -bucket, we double the bucket size, rehash, and deal the bucket -contents into a double-sized set of backing pages. In the future, we -may represent the size as a linear combination of two powers-of-two, -to increase space efficiency. - -To solve the "jackpot case" where a set of records collide under -hashing in a bad way, the implementation will fall back to linear -search across 2**log2_size backing pages on a per-bucket basis. - -To maintain *space* efficiency, we should configure the bucket array -so that backing pages are effectively utilized.

As of this -writing, .../src/vppinfra provides pre-built templates for 8, 16, 20, -24, 40, and 48 byte keys, u8 * vector keys, and 8 byte values. - -See .../src/vppinfra/{bihash_<key-size>_8}.h - -To define the data types, #include a specific template instance, most -often in a subsystem header file: - -```c - #include <vppinfra/bihash_8_8.h> -``` - -If you're building a standalone application, you'll need to define the -various functions by #including the method implementation file in a C -source file. - -The core vpp engine currently uses most if not all of the known bihash -types, so you probably won't need to #include the method -implementation file. - - -```c - #include <vppinfra/bihash_template.c> -``` - -Add an instance of the selected bihash data structure to e.g. a -"main_t" structure: - -```c - typedef struct - { - ... - BVT (clib_bihash) hash_table; - or - clib_bihash_8_8_t hash_table; - ... - } my_main_t; -``` - -The BV macro concatenate its argument with the value of the -preprocessor symbol BIHASH_TYPE. The BVT macro concatenates its -argument with the value of BIHASH_TYPE and the fixed-string "_t". So -in the above example, BVT (clib_bihash) generates "clib_bihash_8_8_t". - -If you're sure you won't decide to change the template / type name -later, it's perfectly OK to code "clib_bihash_8_8_t" and so forth. - -In fact, if you #include multiple template instances in a single -source file, you **must** use fully-enumerated type names. The macros -stand no chance of working. - -### Initializing a bihash table - -Call the init function as shown. As a rough guide, pick a number of -buckets which is approximately -number_of_expected_records/BIHASH_KVP_PER_PAGE from the relevant -template instance header-file.

For one thing, the iterator -template does _not_ take the bihash hash table writer lock.

By luck, assume that one or more of the added entries causes -the __current bucket__ to split-and-rehash. - -Since we rehash KVP's to different pages based on what amounts to a -different hash function, either of these things can go wrong: - -* We may revisit previously-visited entries. Depending on how one -coded the use-case, we could end up in a recursive-add situation. - -* We may skip entries that have not been visited - -One could build an add-safe iterator, at a significant cost in -performance: copy the entire bucket, and walk the copy. - -It's hard to imagine a worthwhile add-during walk use-case in the -first place; let alone one which couldn't be implemented by walking -the table without modifying it, then adding a set of records. - -### Creating a new template instance - -Creating a new template is easy. Use one of the existing templates as -a model, and make the obvious changes. The hash and key_compare -methods are performance-critical in multiple senses. - -If the key compare method is slow, every lookup will be slow. If the -hash function is slow, same story. If the hash function has poor -statistical properties, space efficiency will suffer. In the limit, a -bad enough hash function will cause large portions of the table to -revert to linear search. - -Use of the best available vector unit is well worth the trouble in the -hash and key_compare functions. diff --git a/docs/gettingstarted/developers/binary_api_support.rst b/docs/gettingstarted/developers/binary_api_support.rst deleted file mode 100644 index f93bbc296fc..00000000000 --- a/docs/gettingstarted/developers/binary_api_support.rst +++ /dev/null @@ -1,485 +0,0 @@ -.. _binary_api_support: - -.. toctree:: - -Binary API Support -================== - -VPP provides a binary API scheme to allow a wide variety of client -codes to program data-plane tables.

We -subtract the previous interval end values, and use exponential -smoothing to merge the new clock rate sample into the clocks_per_second -parameter. - -As of this writing, we maintain the clock rate by way of the following -first-order differential equation: - - -``` - clocks_per_second(t) = clocks_per_second(t-1) * K + sample_cps(t)*(1-K) - where K = e**(-1.0/3.75); -``` - -This yields a per observation "half-life" of 1 minute. Empirically, -the clock rate converges within 5 minutes, and appears to maintain -near-perfect agreement with the kernel clock in the face of ongoing -NTP time adjustments. - -See ./src/vppinfra/time.c:clib_time_verify_frequency(...) to look at -the rate adjustment algorithm. The code rejects frequency samples -corresponding to the sort of adjustment which might occur if someone -changes the gold standard kernel clock by several seconds. - -### Monotonic timebase support - -Particularly during system initialization, the "gold standard" system -reference clock can change by a large amount, in an instant. It's not -a best practice to yank the reference clock - in either direction - by -hours or days. In fact, some poorly-constructed use-cases do so. - -To deal with this reality, clib_time_now(...) returns the number of -seconds since vpp started, *guaranteed to be monotonically -increasing, no matter what happens to the system reference clock*. - -This is first-order important, to avoid breaking every active timer in -the system. The vpp host stack alone may account for tens of millions -of active timers. It's utterly impractical to track down and fix -timers, so we must deal with the issue at the timebase level. - -Here's how it works. Prior to adjusting the clock rate, we collect the -kernel reference clock and the cpu clock: - -``` - /* Ask the kernel and the CPU what time it is... */ - now_reference = unix_time_now (); - now_clock = clib_cpu_time_now (); -``` - -Compute changes for both clocks since the last rate adjustment, -roughly 15 seconds ago: - -``` - /* Compute change in the reference clock */ - delta_reference = now_reference - c->last_verify_reference_time; - - /* And change in the CPU clock */ - delta_clock_in_seconds = (f64) (now_clock - c->last_verify_cpu_time) * - c->seconds_per_clock; -``` - -Delta_reference is key. Almost 100% of the time, delta_reference and -delta_clock_in_seconds are identical modulo one system-call -time. However, NTP or a privileged user can yank the system reference -time - in either direction - by an hour, a day, or a decade. - -As described above, clib_time_now(...) must return monotonically -increasing answers to the question "how long has it been since vpp -started, in seconds." To do that, the clock rate adjustment algorithm -begins by recomputing the initial reference time: - -``` - c->init_reference_time += (delta_reference - delta_clock_in_seconds); -``` - -It's easy to convince yourself that if the reference clock changes by -15.000000 seconds and the cpu clock tick time changes by 15.000000 -seconds, the initial reference time won't change. - -If, on the other hand, delta_reference is -86400.0 and delta clock is -15.0 - reference time jumped backwards by exactly one day in a -15-second rate update interval - we add -86415.0 to the initial -reference time. - -Given the corrected initial reference time, we recompute the total -number of cpu ticks which have occurred since the corrected initial -reference time, at the current clock tick rate: - -``` - c->total_cpu_time = (now_reference - c->init_reference_time) - * c->clocks_per_second; -``` - -### Timebase precision - -Cognoscenti may notice that vlib/clib\_time\_now(...) return a 64-bit -floating-point value; the number of seconds since vpp started. - -Please see [this Wikipedia -article](https://en.wikipedia.org/wiki/Double-precision_floating-point_format) -for more information. C double-precision floating point numbers -(called f64 in the vpp code base) have a 53-bit effective mantissa, -and can accurately represent 15 decimal digits' worth of precision. - -There are 315,360,000.000001 seconds in ten years plus one -microsecond. That string has exactly 15 decimal digits. The vpp time -base retains 1us precision for roughly 30 years. - -vlib/clib\_time\_now do *not* provide precision in excess of 1e-6 -seconds. If necessary, please use clib_cpu_time_now(...) for direct -access to the CPU clock-cycle counter. Note that the number of CPU -clock cycles per second varies significantly across CPU architectures. - -Timer Wheels ------------- - -Vppinfra includes configurable timer wheel support. See the source -code in .../src/vppinfra/tw_timer_template.[ch], as well as a -considerable number of template instances defined in -.../src/vppinfra/tw_timer_<wheel-geometry-spec>.[ch]. - -Instantiation of tw_timer_template.h generates named structures to -implement specific timer wheel geometries. Choices include: number of -timer wheels (currently, 1 or 2), number of slots per ring (a power of -two), and the number of timers per "object handle". - -Internally, user object/timer handles are 32-bit integers, so if one -selects 16 timers/object (4 bits), the resulting timer wheel handle is -limited to 2**28 objects. - -Here are the specific settings required to generate a single 2048 slot -wheel which supports 2 timers per object: - -``` - #define TW_TIMER_WHEELS 1 - #define TW_SLOTS_PER_RING 2048 - #define TW_RING_SHIFT 11 - #define TW_RING_MASK (TW_SLOTS_PER_RING -1) - #define TW_TIMERS_PER_OBJECT 2 - #define LOG2_TW_TIMERS_PER_OBJECT 1 - #define TW_SUFFIX _2t_1w_2048sl - #define TW_FAST_WHEEL_BITMAP 0 - #define TW_TIMER_ALLOW_DUPLICATE_STOP 0 -``` - -See tw_timer_2t_1w_2048sl.h for a complete -example. - -tw_timer_template.h is not intended to be #included directly. Client -codes can include multiple timer geometry header files, although -extreme caution would required to use the TW and TWT macros in such a -case. - -### API usage examples - -The unit test code in .../src/vppinfra/test_tw_timer.c provides a -concrete API usage example. It uses a synthetic clock to rapidly -exercise the underlying tw_timer_expire_timers(...) template. - -There are not many API routines to call. - -#### Initialize a two-timer, single 2048-slot wheel w/ a 1-second timer granularity - -``` - tw_timer_wheel_init_2t_1w_2048sl (&tm->single_wheel, - expired_timer_single_callback, - 1.0 / * timer interval * / ); -``` - -#### Start a timer - -``` - handle = tw_timer_start_2t_1w_2048sl (&tm->single_wheel, elt_index, - [0 | 1] / * timer id * / , - expiration_time_in_u32_ticks); -``` - -#### Stop a timer - -``` - tw_timer_stop_2t_1w_2048sl (&tm->single_wheel, handle); -``` - -#### An expired timer callback - -``` - static void - expired_timer_single_callback (u32 * expired_timers) - { - int i; - u32 pool_index, timer_id; - tw_timer_test_elt_t *e; - tw_timer_test_main_t *tm = &tw_timer_test_main; - - for (i = 0; i < vec_len (expired_timers); - { - pool_index = expired_timers[i] & 0x7FFFFFFF; - timer_id = expired_timers[i] >> 31; - - ASSERT (timer_id == 1); - - e = pool_elt_at_index (tm->test_elts, pool_index); - - if (e->expected_to_expire != tm->single_wheel.current_tick) - { - fformat (stdout, "[%d] expired at %d not %d\n", - e - tm->test_elts, tm->single_wheel.current_tick, - e->expected_to_expire); - } - pool_put (tm->test_elts, e); - } - } -``` - -We use wheel timers extensively in the vpp host stack. Each TCP -session needs 5 timers, so supporting 10 million flows requires up to -50 million concurrent timers. - -Timers rarely expire, so it's of utmost important that stopping and -restarting a timer costs as few clock cycles as possible. - -Stopping a timer costs a doubly-linked list dequeue. Starting a timer -involves modular arithmetic to determine the correct timer wheel and -slot, and a list head enqueue. - -Expired timer processing generally involves bulk link-list retirement -with user callback presentation. Some additional complexity at wheel -wrap time, to relocate timers from slower-turning timer wheels into -faster-turning wheels. - -Format ------- - -Vppinfra format is roughly equivalent to printf. - -Format has a few properties worth mentioning. Format's first argument is -a (u8 \*) vector to which it appends the result of the current format -operation. Chaining calls is very easy: - -```c - u8 * result; - - result = format (0, "junk = %d, ", junk); - result = format (result, "more junk = %d\n", more_junk); -``` - -As previously noted, NULL pointers are perfectly proper 0-length -vectors. Format returns a (u8 \*) vector, **not** a C-string. If you -wish to print a (u8 \*) vector, use the "%v" format string. If you need -a (u8 \*) vector which is also a proper C-string, either of these -schemes may be used: - -```c - vec_add1 (result, 0) - or - result = format (result, "<whatever>%c", 0); -``` - -Remember to vec\_free() the result if appropriate. Be careful not to -pass format an uninitialized (u8 \*). - -Format implements a particularly handy user-format scheme via the "%U" -format specification. For example: - -```c - u8 * format_junk (u8 * s, va_list *va) - { - junk = va_arg (va, u32); - s = format (s, "%s", junk); - return s; - } - - result = format (0, "junk = %U, format_junk, "This is some junk"); -``` - -format\_junk() can invoke other user-format functions if desired. The -programmer shoulders responsibility for argument type-checking. It is -typical for user format functions to blow up spectacularly if the -va\_arg(va, type) macros don't match the caller's idea of reality. - -Unformat --------- - -Vppinfra unformat is vaguely related to scanf, but considerably more -general. - -A typical use case involves initializing an unformat\_input\_t from -either a C-string or a (u8 \*) vector, then parsing via unformat() as -follows: - -```c - unformat_input_t input; - u8 *s = "<some-C-string>"; - - unformat_init_string (&input, (char *) s, strlen((char *) s)); - /* or */ - unformat_init_vector (&input, <u8-vector>); -``` - -Then loop parsing individual elements: - -```c - while (unformat_check_input (&input) != UNFORMAT_END_OF_INPUT) - { - if (unformat (&input, "value1 %d", &value1)) - ;/* unformat sets value1 */ - else if (unformat (&input, "value2 %d", &value2) - ;/* unformat sets value2 */ - else - return clib_error_return (0, "unknown input '%U'", - format_unformat_error, input); - } -``` - -As with format, unformat implements a user-unformat function capability -via a "%U" user unformat function scheme. Generally, one can trivially -transform "format (s, "foo %d", foo) -> "unformat (input, "foo %d", &foo)". - -Unformat implements a couple of handy non-scanf-like format specifiers: - -```c - unformat (input, "enable %=", &enable, 1 /* defaults to 1 */); - unformat (input, "bitzero %|", &mask, (1<<0)); - unformat (input, "bitone %|", &mask, (1<<1)); - <etc> -``` - -The phrase "enable %=" means "set the supplied variable to the default -value" if unformat parses the "enable" keyword all by itself. If -unformat parses "enable 123" set the supplied variable to 123. - -We could clean up a number of hand-rolled "verbose" + "verbose %d" -argument parsing codes using "%=". - -The phrase "bitzero %|" means "set the specified bit in the supplied -bitmask" if unformat parses "bitzero". Although it looks like it could -be fairly handy, it's very lightly used in the code base. - -`%_` toggles whether or not to skip input white space. - -For transition from skip to no-skip in middle of format string, skip input white space. For example, the following: - -```c -fmt = "%_%d.%d%_->%_%d.%d%_" -unformat (input, fmt, &one, &two, &three, &four); -``` -matches input "1.2 -> 3.4". -Without this, the space after -> does not get skipped. - - -``` - -### How to parse a single input line - -Debug CLI command functions MUST NOT accidentally consume input -belonging to other debug CLI commands. Otherwise, it's impossible to -script a set of debug CLI commands which "work fine" when issued one -at a time. - -This bit of code is NOT correct: - -```c - /* Eats script input NOT beloging to it, and chokes! */ - while (unformat_check_input (input) != UNFORMAT_END_OF_INPUT) - { - if (unformat (input, ...)) - ; - else if (unformat (input, ...)) - ; - else - return clib_error_return (0, "parse error: '%U'", - format_unformat_error, input); - } - } -``` - -When executed as part of a script, such a function will return "parse -error: '<next-command-text>'" every time, unless it happens to be the -last command in the script. - -Instead, use "unformat_line_input" to consume the rest of a line's -worth of input - everything past the path specified in the -VLIB_CLI_COMMAND declaration. - -For example, unformat_line_input with "my_command" set up as shown -below and user input "my path is clear" will produce an -unformat_input_t that contains "is clear". - -```c - VLIB_CLI_COMMAND (...) = { - .path = "my path", - }; -``` - -Here's a bit of code which shows the required mechanics, in full: - -```c - static clib_error_t * - my_command_fn (vlib_main_t * vm, - unformat_input_t * input, - vlib_cli_command_t * cmd) - { - unformat_input_t _line_input, *line_input = &_line_input; - u32 this, that; - clib_error_t *error = 0; - - if (!unformat_user (input, unformat_line_input, line_input)) - return 0; - - /* - * Here, UNFORMAT_END_OF_INPUT is at the end of the line we consumed, - * not at the end of the script... - */ - while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) - { - if (unformat (line_input, "this %u", &this)) - ; - else if (unformat (line_input, "that %u", &that)) - ; - else - { - error = clib_error_return (0, "parse error: '%U'", - format_unformat_error, line_input); - goto done; - } - } - - <do something based on "this" and "that", etc> - - done: - unformat_free (line_input); - return error; - } - /* *INDENT-OFF* */ - VLIB_CLI_COMMAND (my_command, static) = { - .path = "my path", - .function = my_command_fn", - }; - /* *INDENT-ON* */ - -``` - - -Vppinfra errors and warnings ----------------------------- - -Many functions within the vpp dataplane have return-values of type -clib\_error\_t \*. Clib\_error\_t's are arbitrary strings with a bit of -metadata \[fatal, warning\] and are easy to announce. Returning a NULL -clib\_error\_t \* indicates "A-OK, no error." - -Clib\_warning(format-args) is a handy way to add debugging -output; clib warnings prepend function:line info to unambiguously locate -the message source. Clib\_unix\_warning() adds perror()-style Linux -system-call information. In production images, clib\_warnings result in -syslog entries. - -Serialization -------------- - -Vppinfra serialization support allows the programmer to easily serialize -and unserialize complex data structures. - -The underlying primitive serialize/unserialize functions use network -byte-order, so there are no structural issues serializing on a -little-endian host and unserializing on a big-endian host. diff --git a/docs/gettingstarted/developers/metadata.md b/docs/gettingstarted/developers/metadata.md deleted file mode 100644 index 34400ef4568..00000000000 --- a/docs/gettingstarted/developers/metadata.md +++ /dev/null @@ -1,190 +0,0 @@ -Buffer Metadata -=============== - -Each vlib_buffer_t (packet buffer) carries buffer metadata which -describes the current packet-processing state.

-VLIB (Vector Processing Library) -================================ - -The files associated with vlib are located in the ./src/{vlib, -vlibapi, vlibmemory} folders. These libraries provide vector -processing support including graph-node scheduling, reliable multicast -support, ultra-lightweight cooperative multi-tasking threads, a CLI, -plug in .DLL support, physical memory and Linux epoll support. Parts of -this library embody US Patent 7,961,636. - -Init function discovery ------------------------ - -vlib applications register for various \[initialization\] events by -placing structures and \_\_attribute\_\_((constructor)) functions into -the image. At appropriate times, the vlib framework walks -constructor-generated singly-linked structure lists, performs a -topological sort based on specified constraints, and calls the -indicated functions. Vlib applications create graph nodes, add CLI -functions, start cooperative multi-tasking threads, etc. etc. using -this mechanism. - -vlib applications invariably include a number of VLIB\_INIT\_FUNCTION -(my\_init\_function) macros. - -Each init / configure / etc. function has the return type clib\_error\_t -\*. Make sure that the function returns 0 if all is well, otherwise the -framework will announce an error and exit. - -vlib applications must link against vppinfra, and often link against -other libraries such as VNET. In the latter case, it may be necessary to -explicitly reference symbol(s) otherwise large portions of the library -may be AWOL at runtime. - -### Init function construction and constraint specification - -It's easy to add an init function: - -``` - static clib_error_t *my_init_function (vlib_main_t *vm) - { - /* ... initialize things ... */ - - return 0; // or return clib_error_return (0, "BROKEN!"); - } - VLIB_INIT_FUNCTION(my_init_function); -``` - -As given, my_init_function will be executed "at some point," but with -no ordering guarantees. - -Specifying ordering constraints is easy: - -``` - VLIB_INIT_FUNCTION(my_init_function) = - { - .runs_before = VLIB_INITS("we_run_before_function_1", - "we_run_before_function_2"), - .runs_after = VLIB_INITS("we_run_after_function_1", - "we_run_after_function_2), - }; -``` - -It's also easy to specify bulk ordering constraints of the form "a -then b then c then d": - -``` - VLIB_INIT_FUNCTION(my_init_function) = - { - .init_order = VLIB_INITS("a", "b", "c", "d"), - }; -``` - -It's OK to specify all three sorts of ordering constraints for a -single init function, although it's hard to imagine why it would be -necessary. - - -Node Graph Initialization -------------------------- - -vlib packet-processing applications invariably define a set of graph -nodes to process packets. - -One constructs a vlib\_node\_registration\_t, most often via the -VLIB\_REGISTER\_NODE macro. At runtime, the framework processes the set -of such registrations into a directed graph. It is easy enough to add -nodes to the graph at runtime. The framework does not support removing -nodes. - -vlib provides several types of vector-processing graph nodes, primarily -to control framework dispatch behaviors. The type member of the -vlib\_node\_registration\_t functions as follows: - -- VLIB\_NODE\_TYPE\_PRE\_INPUT - run before all other node types -- VLIB\_NODE\_TYPE\_INPUT - run as often as possible, after pre\_input - nodes -- VLIB\_NODE\_TYPE\_INTERNAL - only when explicitly made runnable by - adding pending frames for processing -- VLIB\_NODE\_TYPE\_PROCESS - only when explicitly made runnable. - "Process" nodes are actually cooperative multi-tasking threads. They - **must** explicitly suspend after a reasonably short period of time. - -For a precise understanding of the graph node dispatcher, please read -./src/vlib/main.c:vlib\_main\_loop. - -Graph node dispatcher ---------------------- - -Vlib\_main\_loop() dispatches graph nodes. The basic vector processing -algorithm is diabolically simple, but may not be obvious from even a -long stare at the code. Here's how it works: some input node, or set of -input nodes, produce a vector of work to process. The graph node -dispatcher pushes the work vector through the directed graph, -subdividing it as needed, until the original work vector has been -completely processed. At that point, the process recurs. - -This scheme yields a stable equilibrium in frame size, by construction. -Here's why: as the frame size increases, the per-frame-element -processing time decreases. There are several related forces at work; the -simplest to describe is the effect of vector processing on the CPU L1 -I-cache. The first frame element \[packet\] processed by a given node -warms up the node dispatch function in the L1 I-cache. All subsequent -frame elements profit. As we increase the number of frame elements, the -cost per element goes down. - -Under light load, it is a crazy waste of CPU cycles to run the graph -node dispatcher flat-out. So, the graph node dispatcher arranges to wait -for work by sitting in a timed epoll wait if the prevailing frame size -is low. The scheme has a certain amount of hysteresis to avoid -constantly toggling back and forth between interrupt and polling mode. -Although the graph dispatcher supports interrupt and polling modes, our -current default device drivers do not. - -The graph node scheduler uses a hierarchical timer wheel to reschedule -process nodes upon timer expiration. - -Graph dispatcher internals --------------------------- - -This section may be safely skipped. It's not necessary to understand -graph dispatcher internals to create graph nodes. - -Vector Data Structure ---------------------- - -In vpp / vlib, we represent vectors as instances of the vlib_frame_t type: - -```c - typedef struct vlib_frame_t - { - /* Frame flags. */ - u16 flags; - - /* Number of scalar bytes in arguments. */ - u8 scalar_size; - - /* Number of bytes per vector argument. */ - u8 vector_size; - - /* Number of vector elements currently in frame. */ - u16 n_vectors; - - /* Scalar and vector arguments to next node. */ - u8 arguments[0]; - } vlib_frame_t; -``` - -Note that one _could_ construct all kinds of vectors - including -vectors with some associated scalar data - using this structure. In -the vpp application, vectors typically use a 4-byte vector element -size, and zero bytes' worth of associated per-frame scalar data. - -Frames are always allocated on CLIB_CACHE_LINE_BYTES boundaries. -Frames have u32 indices which make use of the alignment property, so -the maximum feasible main heap offset of a frame is -CLIB_CACHE_LINE_BYTES * 0xFFFFFFFF: 64*4 = 256 Gbytes. - -Scheduling Vectors ------------------- - -As you can see, vectors are not directly associated with graph -nodes. We represent that association in a couple of ways. The -simplest is the vlib\_pending\_frame\_t: - -```c - /* A frame pending dispatch by main loop. */ - typedef struct - { - /* Node and runtime for this frame. */ - u32 node_runtime_index; - - /* Frame index (in the heap). */ - u32 frame_index; - - /* Start of next frames for this node. */ - u32 next_frame_index; - - /* Special value for next_frame_index when there is no next frame. */ - #define VLIB_PENDING_FRAME_NO_NEXT_FRAME ((u32) ~0) - } vlib_pending_frame_t; -``` - -Here is the code in .../src/vlib/main.c:vlib_main_or_worker_loop() -which processes frames: - -```c - /* - * Input nodes may have added work to the pending vector. - * Process pending vector until there is nothing left. - * All pending vectors will be processed from input -> output. - */ - for (i = 0; i < _vec_len (nm->pending_frames); i++) - cpu_time_now = dispatch_pending_node (vm, i, cpu_time_now); - /* Reset pending vector for next iteration. */ -``` - -The pending frame node_runtime_index associates the frame with the -node which will process it. - -Complications -------------- - -Fasten your seatbelt. Here's where the story - and the data structures -\- become quite complicated... - -At 100,000 feet: vpp uses a directed graph, not a directed _acyclic_ -graph. It's really quite normal for a packet to visit ip\[46\]-lookup -multiple times. The worst-case: a graph node which enqueues packets to -itself. - -To deal with this issue, the graph dispatcher must force allocation of -a new frame if the current graph node's dispatch function happens to -enqueue a packet back to itself. - -There are no guarantees that a pending frame will be processed -immediately, which means that more packets may be added to the -underlying vlib_frame_t after it has been attached to a -vlib_pending_frame_t. Care must be taken to allocate new -frames and pending frames if a (pending\_frame, frame) pair fills. - -Next frames, next frame ownership ---------------------------------- - -The vlib\_next\_frame\_t is the last key graph dispatcher data structure: - -```c - typedef struct - { - /* Frame index. */ - u32 frame_index; - - /* Node runtime for this next. */ - u32 node_runtime_index; - - /* Next frame flags. */ - u32 flags; - - /* Reflects node frame-used flag for this next. */ - #define VLIB_FRAME_NO_FREE_AFTER_DISPATCH \ - VLIB_NODE_FLAG_FRAME_NO_FREE_AFTER_DISPATCH - - /* This next frame owns enqueue to node - corresponding to node_runtime_index. */ - #define VLIB_FRAME_OWNER (1 << 15) - - /* Set when frame has been allocated for this next. */ - #define VLIB_FRAME_IS_ALLOCATED VLIB_NODE_FLAG_IS_OUTPUT - - /* Set when frame has been added to pending vector. */ - #define VLIB_FRAME_PENDING VLIB_NODE_FLAG_IS_DROP - - /* Set when frame is to be freed after dispatch. */ - #define VLIB_FRAME_FREE_AFTER_DISPATCH VLIB_NODE_FLAG_IS_PUNT - - /* Set when frame has traced packets. */ - #define VLIB_FRAME_TRACE VLIB_NODE_FLAG_TRACE - - /* Number of vectors enqueue to this next since last overflow. */ - u32 vectors_since_last_overflow; - } vlib_next_frame_t; -``` - -Graph node dispatch functions call vlib\_get\_next\_frame (...) to -set "(u32 \*)to_next" to the right place in the vlib_frame_t -corresponding to the ith arc (aka next0) from the current node to the -indicated next node. - -After some scuffling around - two levels of macros - processing -reaches vlib\_get\_next\_frame_internal (...). Get-next-frame-internal -digs up the vlib\_next\_frame\_t corresponding to the desired graph -arc. - -The next frame data structure amounts to a graph-arc-centric frame -cache. Once a node finishes adding element to a frame, it will acquire -a vlib_pending_frame_t and end up on the graph dispatcher's -run-queue. But there's no guarantee that more vector elements won't be -added to the underlying frame from the same (source\_node, -next\_index) arc or from a different (source\_node, next\_index) arc. - -Maintaining consistency of the arc-to-frame cache is necessary. The -first step in maintaining consistency is to make sure that only one -graph node at a time thinks it "owns" the target vlib\_frame\_t. - -Back to the graph node dispatch function. In the usual case, a certain -number of packets will be added to the vlib\_frame\_t acquired by -calling vlib\_get\_next\_frame (...). - -Before a dispatch function returns, it's required to call -vlib\_put\_next\_frame (...) for all of the graph arcs it actually -used. This action adds a vlib\_pending\_frame\_t to the graph -dispatcher's pending frame vector. - -Vlib\_put\_next\_frame makes a note in the pending frame of the frame -index, and also of the vlib\_next\_frame\_t index. - -dispatch\_pending\_node actions -------------------------------- - -The main graph dispatch loop calls dispatch pending node as shown -above. - -Dispatch\_pending\_node recovers the pending frame, and the graph node -runtime / dispatch function. Further, it recovers the next\_frame -currently associated with the vlib\_frame\_t, and detaches the -vlib\_frame\_t from the next\_frame. - -In .../src/vlib/main.c:dispatch\_pending\_node(...), note this stanza: - -```c - /* Force allocation of new frame while current frame is being - dispatched. */ - restore_frame_index = ~0; - if (nf->frame_index == p->frame_index) - { - nf->frame_index = ~0; - nf->flags &= ~VLIB_FRAME_IS_ALLOCATED; - if (!(n->flags & VLIB_NODE_FLAG_FRAME_NO_FREE_AFTER_DISPATCH)) - restore_frame_index = p->frame_index; - } -``` - -dispatch\_pending\_node is worth a hard stare due to the several -second-order optimizations it implements. Almost as an afterthought, -it calls dispatch_node which actually calls the graph node dispatch -function. - -Process / thread model ----------------------- - -vlib provides an ultra-lightweight cooperative multi-tasking thread -model. The graph node scheduler invokes these processes in much the same -way as traditional vector-processing run-to-completion graph nodes; -plus-or-minus a setjmp/longjmp pair required to switch stacks. Simply -set the vlib\_node\_registration\_t type field to -vlib\_NODE\_TYPE\_PROCESS. Yes, process is a misnomer. These are -cooperative multi-tasking threads. - -As of this writing, the default stack size is 2<<15 = 32kb. -Initialize the node registration's process\_log2\_n\_stack\_bytes member -as needed. The graph node dispatcher makes some effort to detect stack -overrun, e.g. by mapping a no-access page below each thread stack. - -Process node dispatch functions are expected to be "while(1) { }" loops -which suspend when not otherwise occupied, and which must not run for -unreasonably long periods of time. - -"Unreasonably long" is an application-dependent concept. Over the years, -we have constructed frame-size sensitive control-plane nodes which will -use a much higher fraction of the available CPU bandwidth when the frame -size is low. The classic example: modifying forwarding tables. So long -as the table-builder leaves the forwarding tables in a valid state, one -can suspend the table builder to avoid dropping packets as a result of -control-plane activity. - -Process nodes can suspend for fixed amounts of time, or until another -entity signals an event, or both. See the next section for a description -of the vlib process event mechanism. - -When running in vlib process context, one must pay strict attention to -loop invariant issues. If one walks a data structure and calls a -function which may suspend, one had best know by construction that it -cannot change. Often, it's best to simply make a snapshot copy of a data -structure, walk the copy at leisure, then free the copy. - -Process events --------------- - -The vlib process event mechanism API is extremely lightweight and easy -to use. Here is a typical example: - -```c - vlib_main_t *vm = &vlib_global_main; - uword event_type, * event_data = 0; - - while (1) - { - vlib_process_wait_for_event_or_clock (vm, 5.0 /* seconds */); - - event_type = vlib_process_get_events (vm, &event_data); - - switch (event_type) { - case EVENT1: - handle_event1s (event_data); - break; - - case EVENT2: - handle_event2s (event_data); - break; - - case ~0: /* 5-second idle/periodic */ - handle_idle (); - break; - - default: /* bug! */ - ASSERT (0); - } - - vec_reset_length(event_data); - } -``` - -In this example, the VLIB process node waits for an event to occur, or -for 5 seconds to elapse. The code demuxes on the event type, calling -the appropriate handler function. Each call to -vlib\_process\_get\_events returns a vector of per-event-type data -passed to successive vlib\_process\_signal\_event calls; it is a -serious error to process only event\_data\[0\]. - -Resetting the event\_data vector-length to 0 \[instead of calling -vec\_free\] means that the event scheme doesn't burn cycles continuously -allocating and freeing the event data vector. This is a common vppinfra -/ vlib coding pattern, well worth using when appropriate. - -Signaling an event is easy, for example: - -```c - vlib_process_signal_event (vm, process_node_index, EVENT1, - (uword)arbitrary_event1_data); /* and so forth */ -``` - -One can either know the process node index by construction - dig it out -of the appropriate vlib\_node\_registration\_t - or by finding the -vlib\_node\_t with vlib\_get\_node\_by\_name(...). - -Buffers -------- - -vlib buffering solves the usual set of packet-processing problems, -albeit at high performance. Key in terms of performance: one ordinarily -allocates / frees N buffers at a time rather than one at a time. Except -when operating directly on a specific buffer, one deals with buffers by -index, not by pointer. - -Packet-processing frames are u32\[\] arrays, not -vlib\_buffer\_t\[\] arrays. - -Packets comprise one or more vlib buffers, chained together as required. -Multiple particle sizes are supported; hardware input nodes simply ask -for the required size(s). Coalescing support is available. For obvious -reasons one is discouraged from writing one's own wild and wacky buffer -chain traversal code. - -vlib buffer headers are allocated immediately prior to the buffer data -area. In typical packet processing this saves a dependent read wait: -given a buffer's address, one can prefetch the buffer header -\[metadata\] at the same time as the first cache line of buffer data. - -Buffer header metadata (vlib\_buffer\_t) includes the usual rewrite -expansion space, a current\_data offset, RX and TX interface indices, -packet trace information, and a opaque areas. - -The opaque data is intended to control packet processing in arbitrary -subgraph-dependent ways. The programmer shoulders responsibility for -data lifetime analysis, type-checking, etc. - -Buffers have reference-counts in support of e.g. multicast replication. - -Shared-memory message API -------------------------- - -Local control-plane and application processes interact with the vpp -dataplane via asynchronous message-passing in shared memory over -unidirectional queues. The same application APIs are available via -sockets. - -Capturing API traces and replaying them in a simulation environment -requires a disciplined approach to the problem. This seems like a -make-work task, but it is not. When something goes wrong in the -control-plane after 300,000 or 3,000,000 operations, high-speed replay -of the events leading up to the accident is a huge win. - -The shared-memory message API message allocator vl\_api\_msg\_alloc uses -a particularly cute trick. Since messages are processed in order, we try -to allocate message buffering from a set of fixed-size, preallocated -rings. Each ring item has a "busy" bit. Freeing one of the preallocated -message buffers merely requires the message consumer to clear the busy -bit. No locking required. - -Debug CLI ---------- - -Adding debug CLI commands to VLIB applications is very simple. - -Here is a complete example: - -```c - static clib_error_t * - show_ip_tuple_match (vlib_main_t * vm, - unformat_input_t * input, - vlib_cli_command_t * cmd) - { - vlib_cli_output (vm, "%U\n", format_ip_tuple_match_tables, &routing_main); - return 0; - } - - /* *INDENT-OFF* */ - static VLIB_CLI_COMMAND (show_ip_tuple_command) = - { - .path = "show ip tuple match", - .short_help = "Show ip 5-tuple match-and-broadcast tables", - .function = show_ip_tuple_match, - }; - /* *INDENT-ON* */ -``` - -This example implements the "show ip tuple match" debug cli -command. In ordinary usage, the vlib cli is available via the "vppctl" -application, which sends traffic to a named pipe. One can configure -debug CLI telnet access on a configurable port. - -The cli implementation has an output redirection facility which makes it -simple to deliver cli output via shared-memory API messaging, - -Particularly for debug or "show tech support" type commands, it would be -wasteful to write vlib application code to pack binary data, write more -code elsewhere to unpack the data and finally print the answer. If a -certain cli command has the potential to hurt packet processing -performance by running for too long, do the work incrementally in a -process node. The client can wait. - -### Macro expansion - -The vpp debug CLI engine includes a recursive macro expander. This -is quite useful for factoring out address and/or interface name -specifics: - -``` - define ip1 192.168.1.1/24 - define ip2 192.168.2.1/24 - define iface1 GigabitEthernet3/0/0 - define iface2 loop1 - - set int ip address $iface1 $ip1 - set int ip address $iface2 $(ip2) - - undefine ip1 - undefine ip2 - undefine iface1 - undefine iface2 -``` - -Each socket (or telnet) debug CLI session has its own macro -tables. All debug CLI sessions which use CLI_INBAND binary API -messages share a single table. - -The macro expander recognizes circular defintions: - -``` - define foo \$(bar) - define bar \$(mumble) - define mumble \$(foo) -``` - -At 8 levels of recursion, the macro expander throws up its hands and -replies "CIRCULAR." - -### Macro-related debug CLI commands - -In addition to the "define" and "undefine" debug CLI commands, use -"show macro [noevaluate]" to dump the macro table. The "echo" debug -CLI command will evaluate and print its argument: - -``` - vpp# define foo This\ Is\ Foo - vpp# echo $foo - This Is Foo -``` - -Handing off buffers between threads ------------------------------------ - -Vlib includes an easy-to-use mechanism for handing off buffers between -worker threads. A typical use-case: software ingress flow hashing. At -a high level, one creates a per-worker-thread queue which sends packets -to a specific graph node in the indicated worker thread. With the -queue in hand, enqueue packets to the worker thread of your choice. - -### Initialize a handoff queue - -Simple enough, call vlib_frame_queue_main_init: - -```c - main_ptr->frame_queue_index - = vlib_frame_queue_main_init (dest_node.index, frame_queue_size); -``` - -Frame_queue_size means what it says: the number of frames which may be -queued. Since frames contain 1...256 packets, frame_queue_size should -be a reasonably small number (32...64). If the frame queue producer(s) -are faster than the frame queue consumer(s), congestion will -occur. Suggest letting the enqueue operator deal with queue -congestion, as shown in the enqueue example below. - -Under the floorboards, vlib_frame_queue_main_init creates an input queue -for each worker thread. - -Please do NOT create frame queues until it's clear that they will be -used. Although the main dispatch loop is reasonably smart about how -often it polls the (entire set of) frame queues, polling unused frame -queues is a waste of clock cycles. - -### Hand off packets - -The actual handoff mechanics are simple, and integrate nicely with -a typical graph-node dispatch function: - -```c - always_inline uword - do_handoff_inline (vlib_main_t * vm, - vlib_node_runtime_t * node, vlib_frame_t * frame, - int is_ip4, int is_trace) - { - u32 n_left_from, *from; - vlib_buffer_t *bufs[VLIB_FRAME_SIZE], **b; - u16 thread_indices [VLIB_FRAME_SIZE]; - u16 nexts[VLIB_FRAME_SIZE], *next; - u32 n_enq; - htest_main_t *hmp = &htest_main; - int i; - - from = vlib_frame_vector_args (frame); - n_left_from = frame->n_vectors; - - vlib_get_buffers (vm, from, bufs, n_left_from); - next = nexts; - b = bufs; - - /* - * Typical frame traversal loop, details vary with - * use case. Make sure to set thread_indices[i] with - * the desired destination thread index. You may - * or may not bother to set next[i]. - */ - - for (i = 0; i < frame->n_vectors; i++) - { - <snip> - /* Pick a thread to handle this packet */ - thread_indices[i] = f (packet_data_or_whatever); - <snip> - - b += 1; - next += 1; - n_left_from -= 1; - } - - /* Enqueue buffers to threads */ - n_enq = - vlib_buffer_enqueue_to_thread (vm, node, hmp->frame_queue_index, - from, thread_indices, frame->n_vectors, - 1 /* drop on congestion */); - /* Typical counters, - if (n_enq < frame->n_vectors) - vlib_node_increment_counter (vm, node->node_index, - XXX_ERROR_CONGESTION_DROP, - frame->n_vectors - n_enq); - vlib_node_increment_counter (vm, node->node_index, - XXX_ERROR_HANDED_OFF, n_enq); - return frame->n_vectors; -} -``` - -Notes about calling vlib_buffer_enqueue_to_thread(...): - -* If you pass "drop on congestion" non-zero, all packets in the -inbound frame will be consumed one way or the other. This is the -recommended setting. - -* In the drop-on-congestion case, please don't try to "help" in the -enqueue node by freeing dropped packets, or by pushing them to -"error-drop." Either of those actions would be a severe error. - -* It's perfectly OK to enqueue packets to the current thread. - -Handoff Demo Plugin -------------------- - -Check out the sample (plugin) example in -.../src/examples/handoffdemo. If you want to build the handoff demo plugin: - -``` -$ cd .../src/plugins -$ ln -s ../examples/handoffdemo -``` - -This plugin provides a simple example of how to hand off packets -between threads.

Tasks like sending keepalives or actively opening connections -come to mind. Its not difficult, but accurate buffer metadata setup is -required. - -### Allocating Buffers - -Use vlib_buffer_alloc, which allocates a set of buffer indices. For -low-performance applications, it's OK to allocate one buffer at a -time. Note that vlib_buffer_alloc(...) does NOT initialize buffer -metadata. See below. - -In high-performance cases, allocate a vector of buffer indices, -and hand them out from the end of the vector; decrement _vec_len(..) -as buffer indices are allocated. See tcp_alloc_tx_buffers(...) and -tcp_get_free_buffer_index(...) for an example. - -### Buffer Initialization Example - -The following example shows the **main points**, but is not to be -blindly cut-'n-pasted. - -```c - u32 bi0; - vlib_buffer_t *b0; - ip4_header_t *ip; - udp_header_t *udp; - - /* Allocate a buffer */ - if (vlib_buffer_alloc (vm, &bi0, 1) != 1) - return -1; - - b0 = vlib_get_buffer (vm, bi0); - - /* At this point b0->current_data = 0, b0->current_length = 0 */ - - /* - * Copy data into the buffer.

Set non-zero to use another fib */ - vnet_buffer (b0)->sw_if_index[VLIB_TX] = 0; - -``` - -If your use-case calls for large packet transmission, use -vlib_buffer_chain_append_data_with_alloc(...) to create the requisite -buffer chain. - -### Enqueueing packets for lookup and transmission - -The simplest way to send a set of packets is to use -vlib_get_frame_to_node(...) to allocate fresh frame(s) to -ip4_lookup_node or ip6_lookup_node, add the constructed buffer -indices, and dispatch the frame using vlib_put_frame_to_node(...). - -```c - vlib_frame_t *f; - f = vlib_get_frame_to_node (vm, ip4_lookup_node.index); - f->n_vectors = vec_len(buffer_indices_to_send); - to_next = vlib_frame_vector_args (f); - - for (i = 0; i < vec_len (buffer_indices_to_send); i++) - to_next[i] = buffer_indices_to_send[i]; - - vlib_put_frame_to_node (vm, ip4_lookup_node_index, f); -``` - -It is inefficient to allocate and schedule single packet frames. -That's typical in case you need to send one packet per second, but -should **not** occur in a for-loop! - -Packet tracer -------------- - -Vlib includes a frame element \[packet\] trace facility, with a simple -debug CLI interface. The cli is straightforward: "trace add -input-node-name count" to start capturing packet traces. - -To trace 100 packets on a typical x86\_64 system running the dpdk -plugin: "trace add dpdk-input 100". When using the packet generator: -"trace add pg-input 100" - -To display the packet trace: "show trace" - -Each graph node has the opportunity to capture its own trace data. It is -almost always a good idea to do so. The trace capture APIs are simple. - -The packet capture APIs snapshoot binary data, to minimize processing at -capture time. Each participating graph node initialization provides a -vppinfra format-style user function to pretty-print data when required -by the VLIB "show trace" command. - -Set the VLIB node registration ".format\_trace" member to the name of -the per-graph node format function. - -Here's a simple example: - -```c - u8 * my_node_format_trace (u8 * s, va_list * args) - { - vlib_main_t * vm = va_arg (*args, vlib_main_t *); - vlib_node_t * node = va_arg (*args, vlib_node_t *); - my_node_trace_t * t = va_arg (*args, my_trace_t *); - - s = format (s, "My trace data was: %d", t-><whatever>); - - return s; - } -``` - -The trace framework hands the per-node format function the data it -captured as the packet whizzed by. The format function pretty-prints the -data as desired. - -Graph Dispatcher Pcap Tracing ------------------------------ - -The vpp graph dispatcher knows how to capture vectors of packets in pcap -format as they're dispatched. The pcap captures are as follows: - -``` - VPP graph dispatch trace record description: - - 0 1 2 3 - 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Major Version | Minor Version | NStrings | ProtoHint | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Buffer index (big endian) | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - + VPP graph node name ... ... | NULL octet | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Buffer Metadata ... ... | NULL octet | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Buffer Opaque ... ... | NULL octet | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Buffer Opaque 2 ... ... | NULL octet | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | VPP ASCII packet trace (if NStrings > 4) | NULL octet | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Packet data (up to 16K) | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ -``` - -Graph dispatch records comprise a version stamp, an indication of how -many NULL-terminated strings will follow the record header and preceed -packet data, and a protocol hint. - -The buffer index is an opaque 32-bit cookie which allows consumers of -these data to easily filter/track single packets as they traverse the -forwarding graph. - -Multiple records per packet are normal, and to be expected. Packets -will appear multiple times as they traverse the vpp forwarding -graph. In this way, vpp graph dispatch traces are significantly -different from regular network packet captures from an end-station. -This property complicates stateful packet analysis. - -Restricting stateful analysis to records from a single vpp graph node -such as "ethernet-input" seems likely to improve the situation. - -As of this writing: major version = 1, minor version = 0. Nstrings -SHOULD be 4 or 5. Consumers SHOULD be wary values less than 4 or -greater than 5. They MAY attempt to display the claimed number of -strings, or they MAY treat the condition as an error. - -Here is the current set of protocol hints: - -```c - typedef enum - { - VLIB_NODE_PROTO_HINT_NONE = 0, - VLIB_NODE_PROTO_HINT_ETHERNET, - VLIB_NODE_PROTO_HINT_IP4, - VLIB_NODE_PROTO_HINT_IP6, - VLIB_NODE_PROTO_HINT_TCP, - VLIB_NODE_PROTO_HINT_UDP, - VLIB_NODE_N_PROTO_HINTS, - } vlib_node_proto_hint_t; -``` - -Example: VLIB_NODE_PROTO_HINT_IP6 means that the first octet of packet -data SHOULD be 0x60, and should begin an ipv6 packet header. - -Downstream consumers of these data SHOULD pay attention to the -protocol hint.

Each of "pcap trace rx", "pcap trace tx", -and "pcap trace drop" is implemented.

Once - <nnnn> packets have been received, the trace buffer buffer is flushed - to the indicated file. Defaults to 1000. Can only be updated if packet - capture is off. - -- <b>max-bytes-per-pkt _nnnn_</b> - maximum number of bytes to trace - on a per-packet basis. Must be >32 and less than 9000. Default value: - 512. - -- <b>filter</b> - Use the pcap rx / tx / drop trace filter, which must - be configured. Use <b>classify filter pcap...</b> to configure the - filter. The filter will only be executed if the per-interface or - any-interface tests fail. - -- <b>intfc _interface_ | _any_</b> - Used to specify a given interface, - or use '<em>any</em>' to run packet capture on all interfaces. - '<em>any</em>' is the default if not provided. Settings from a previous - packet capture are preserved, so '<em>any</em>' can be used to reset - the interface setting. - -- <b>file _filename_</b> - Used to specify the output filename. The - file will be placed in the '<em>/tmp</em>' directory. If _filename_ - already exists, file will be overwritten. If no filename is - provided, '<em>/tmp/rx.pcap or tx.pcap</em>' will be used, depending - on capture direction. Can only be updated when pcap capture is off. - -- <b>status</b> - Displays the current status and configured - attributes associated with a packet capture. If packet capture is in - progress, '<em>status</em>' also will return the number of packets - currently in the buffer.

The tables are automatically ordered so that matches in the -most specific table are tried first. - -It's reasonably likely that folks will configure a single table with -one or two matches. As a result, we configure 8 hash buckets and 128K -of match rule space by default. One can override the defaults by -specifying "buckets <nnn>" and "memory-size <xxx>" as desired. - -To build up complex filter chains, repeatedly issue the classify -filter debug CLI command.

This datum is used in multiple ways: to select -graph arc feature configuration, to select IP FIBs. Configure -features e.g. on loop0 to exercise those features. - -- **tx-interface \<name\>** - Packets will be transmitted on the -indicated interface. Typically required only when injecting packets -into post-IP-rewrite graph nodes. - -- **pcap \<filename\>** - Replay packets from the indicated pcap -capture file. "make test" makes extensive use of this feature: -generate packets using scapy, save them in a .pcap file, then inject -them into the vpp graph via a vpp pg "pcap \<filename\>" stream -definition - -- **worker \<nn\>** - Generate packets for the stream using the -indicated vpp worker thread.

The C variant is in vapi.h. - -**C++** - -C++ is provided by vapi.hpp and contains high-level API templates, which are specialized by generated code. - -Generated code -______________ - -Each API file present in the source tree is automatically translated to JSON file, which the code generator parses and generates either C (vapi_c_gen.py) or C++ (vapi_cpp_gen.py) code. - -This can then be included in the client application and provides convenient way to interact with VPP. This includes: - -* automatic byte-swapping -* automatic request-response matching based on context -* automatic casts to appropriate types (type-safety) when calling callbacks -* automatic sending of control-pings for dump messages - -The API supports two modes of operation: - -* blocking -* non-blocking - -In blocking mode, whenever an operation is initiated, the code waits until it can finish. This means that when sending a message, the call blocks until the message can be written to shared memory. Similarly, receiving a message blocks until a message becomes available. On higher level, this also means that when doing a request (e.g. show_version), the call blocks until a response comes back (e.g. show_version_reply). - -In non-blocking mode, these are decoupled, the API returns VAPI_EAGAIN whenever an operation cannot be performed and after sending a request, it's up to the client to wait for and process a response. - -Code generator -______________ - -Python code generator comes in two flavors - C and C++ and generates high-level API headers. All the code is stored in the headers. - -C Usage -_______ - -**Low-level API** - -Refer to inline API documentation in doxygen format in vapi.h header for description of functions. It's recommended to use the safer, high-level API provided by specialized headers (e.g. vpe.api.vapi.h or vpe.api.vapi.hpp). - -**C high-level API** - -*Callbacks* - -The C high-level API is strictly callback-based for maximum efficiency. Whenever an operation is initiated a callback with a callback context is part of that operation. The callback is then invoked when the response (or multiple responses) arrive which are tied to the request. Also, callbacks are invoked whenever an event arrives, if such callback is registered. All the pointers to responses/events point to shared memory and are immediately freed after callback finishes so the client needs to extract/copy any data in which it is interested in. - -**Blocking mode** - -In simple blocking mode, the whole operation (being a simple request or a dump) is finished and it's callback is called (potentially multiple times for dumps) during function call. - -Example pseudo-code for a simple request in this mode: - -vapi_show_version(message, callback, callback_context) - -#. generate unique internal context and assign it to message.header.context -#. byteswap the message to network byte order -#. send message to vpp (message is now consumed and vpp will free it) -#. create internal "outstanding request context" which stores the callback, callback context and the internal context value -#. call dispatch, which in this mode receives and processes responses until the internal "outstanding requests" queue is empty. In blocking mode, this queue always contains at most one item. - -.. note:: - - It's possible for different - unrelated callbacks to be called before the response callbacks is called in cases where e.g. events are stored in shared memory queue. - -**Non-blocking mode** -In non-blocking mode, all the requests are only byte-swapped and the context information along with callbacks is stored locally (so in the above example, only steps 1-4 are executed and step 5 is skipped). Calling dispatch is up to the client application. This allows to alternate between sending/receiving messages or have a dedicated thread which calls dispatch. - -C++ high level API -__________________ - -**Callbacks** - -In C++ API, the response is automatically tied to the corresponding Request, Dump or Event_registration object. Optionally a callback might be specified, which then gets called when the response is received. - -.. note:: - - Responses take up shared memory space and should be freed either manually (in case of result sets) or automatically (by destroying the object owning them) when no longer needed. Once a Request or Dump object was executed, it cannot be re-sent, since the request itself (stores in shared memory) is consumed by vpp and inaccessible (set to nullptr) anymore. - -C++ Usage -_________ - -**Requests & dumps** - -*Create an object of Connection type and call connect() to connect to vpp.* - -#. Create an object of Request or Dump type using it's typedef (e.g. Show_version) -#. Use get_request() to obtain and manipulate the underlying request if required. -#. Issue execute() to send the request. -#. Use either wait_for_response() or dispatch() to wait for the response. -#. Use get_response_state() to get the state and get_response() to read the response. - -**Events** - -*Create a Connection and execute the appropriate Request to subscribe to events (e.g. Want_stats)* - -#. Create an Event_registration with a template argument being the type of event you are interested in. -#. Call dispatch() or wait_for_response() to wait for the event. A callback will be called when an event occurs (if passed to Event_registration() constructor).

-
-set interface ip address [del] <*interface*> <*ip-addr*>/<*mask*> | [all]
-
-Description
--------------
-
-Add an IP Address to an interface or remove and IP Address from an interface.
-The IP Address can be an IPv4 or an IPv6 address. Interfaces may have multiple IPv4 and IPv6
-addresses. There is no concept of primary vs. secondary interface addresses; they're just addresses.
-
-To display the addresses associated with a given interface, use the command **show interface address** <*interface*>.
-
-.. note::
- The debug CLI does not enforce classful mask-width / addressing constraints.
-
-Example Usage
---------------
-
-An example of how to add an IPv4 address to an interface:
-
-.. code-block:: console
-
- vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24
-
-An example of how to add an IPv6 address to an interface:
-
-.. code-block:: console
-
- vpp# set interface ip address GigabitEthernet2/0/0 ::a:1:1:0:7/126
-
-To delete a specific interface ip address:
-
-.. code-block:: console
-
- vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24 del
-
-To delete all interfaces addresses (IPv4 and IPv6):

-Set Interface L2 Bridge
-+++++++++++++++++++++++++
-
-Summary/Usage
--------------
-
-set interface l2 bridge <*interface*> <*bridge-domain-id*> [bvi|uu-fwd] [shg]
-
-Description
--------------
-
-Use this command put an interface into Layer 2 bridge domain. If a bridge-domain with the provided
-bridge-domain-id does not exist, it will be created. Interfaces in a bridge-domain forward packets
-to other interfaces in the same bridge-domain based on destination mac address. To remove an interface
-from a the Layer 2 bridge domain, put the interface in a different mode, for example Layer 3 mode.
-
-Optionally, an interface can be added to a Layer 2 bridge-domain as a Bridged Virtual Interface (bvi).
-Only one interface in a Layer 2 bridge-domain can be a bvi.
-
-Optionally, a split-horizon group can also be specified. This defaults to 0 if not specified.
-
-Example Usage
---------------
-Example of how to configure a Layer 2 bridge-domain with three interfaces (where 200 is the bridge-domain-id):
-
-.. code-block:: console
-
- vpp# set interface l2 bridge GigabitEthernet0/8/0.200 200
-
-This interface is added a BVI interface:
-
-.. code-block:: console
-
- vpp# set interface l2 bridge GigabitEthernet0/9/0.200 200 bvi
-
-This interface also has a split-horizon group of 1 specified:
-
-.. code-block:: console
-
- vpp# set interface l2 bridge GigabitEthernet0/a/0.200 200 1
-
-Example of how to remove an interface from a Layer2 bridge-domain:
-
-.. code-block:: console
-
- vpp# set interface l3 GigabitEthernet0/a/0.200
-
-Declaration and Implementation

--------------
-
-.. code-block:: shell
-
- set interface promiscuous [on|off] <interface>.
-
-.. _setintstate:
-
-Set Interface State
-++++++++++++++++++++
-This command is used to change the admin state (up/down) of an
-interface.
-
-If an interface is down, the optional *punt* flag can also be set. The
-*punt* flag implies the interface is disabled for forwarding but punt
-all traffic to slow-path. Use the *enable* flag to clear *punt* flag
-(interface is still down).
-
-Summary/Usage
--------------
-
-.. code-block:: shell
-
- set interface state <interface> [up|down|punt|enable].
-
-Example Usage
-----------------
-
-Example of how to configure the admin state of an interface to **up**:

-.. code-block:: console
-
- vpp# set interface state GigabitEthernet2/0/0 up
-
-Example of how to configure the admin state of an interface to **down**:
-
-.. code-block:: console
-
- vpp# set interface state GigabitEthernet2/0/0 down

-IP Route
-==========
-
-Summary/Usage
---------------
-
-`ip route [add|del] [count <*n*>] <*dst-ip-addr*>/<*width*> [table <*table-id*>] via [next-hop-address[next-hop-interface] [next-hop-table <*value*>] [weight <*value*>] [preference <*value*>] [udp-encap-id <*value*>] [ip4-lookup-in-table <*value*>] [ip6-lookup-in-table <*value*>] [mpls-lookup-in-table <*value*>] [resolve-via-host] [resolve-via-connected] [rx-ip4 <*interface*>] [out-labels <*value value value*>]`
-
-Description
-------------
-
-This command is used to add or delete IPv4 or IPv6 routes. All IP Addresses
-('<*dst-ip-addr*>/<*width*>', '<*next-hop-ip-addr*>' and '<*adj-hop-ip-addr*>') can be IPv4 or IPv6,
-but all must be of the same form in a single command. To display the current set of routes,
-use the commands 'show ip fib' and 'show ip6 fib'.
-
-Example Usage
---------------
-
-Example of how to add a straight forward static route:
-
-.. code-block:: console
-
- vpp# ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0
-
-Example of how to delete a straight forward static route:
-
-.. code-block:: console
-
- vpp# ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0
-
-Mainly for route add/del performance testing, one can add or delete multiple routes by adding
-'count N' to the previous item:
-
-.. code-block:: console
-
- vpp# ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0
-
-Add multiple routes for the same destination to create equal-cost multipath:
-
-.. code-block:: console
-
- vpp# ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0
-
- vpp# ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0
-
-For unequal-cost multipath, specify the desired weights. This combination of weights
-results in 3/4 of the traffic following the second path, 1/4 following the first path:
-
-.. code-block:: console
-
- vpp# ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1
-
- vpp# ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3
-
-To add a route to a particular FIB table (VRF), use:
-
-.. code-block:: console
-
- vpp# ip route add 172.16.24.0/24 table 7 via GigabitEthernet2/0/0

But rather, the VM is *inside* a Vagrant box, with the box containing additional configuration options you can set, such as VM options, scripts to run on boot, etc. - -This `Vagrant website for boxes <https://app.vagrantup.com/boxes/search>`_ shows you how to configure a basic Vagrantfile for your specific OS and VM software. - - -Box configuration -_________________ - - -Looking at the :ref:`vppVagrantfile`, we can see that the default OS is Ubuntu 16.04 (since the variable *distro* equals *ubuntu1604* if there is no VPP_VAGRANT_DISTRO variable set - thus the **else** case is executed.) - -.. code-block:: ruby - - # -*- mode: ruby -*- - # vi: set ft=ruby : - - Vagrant.configure(2) do |config| - - # Pick the right distro and bootstrap, default is ubuntu1604 - distro = ( ENV['VPP_VAGRANT_DISTRO'] || "ubuntu1604") - if distro == 'centos7' - config.vm.box = "centos/7" - config.vm.box_version = "1708.01" - config.ssh.insert_key = false - else - config.vm.box = "puppetlabs/ubuntu-16.04-64-nocm" - -As mentioned in the previous page, you can specify which OS and VM provider you want for your Vagrant box from the `Vagrant boxes page <https://app.vagrantup.com/boxes/search>`_, and setting your ENV variable appropriately in *env.sh*. - -Next in the Vagrantfile, you see some *config.vm.provision* commands. As paraphrased from `Basic usage of Provisioners <https://www.vagrantup.com/docs/provisioning/basic_usage.html>`_, by default these are only run *once* - during the first boot of the box. - -.. code-block:: ruby - - config.vm.provision :shell, :path => File.join(File.dirname(__FILE__),"update.sh") - config.vm.provision :shell, :path => File.join(File.dirname(__FILE__),"build.sh"), :args => "/vpp vagrant" - -The two lines above set the VM to run two scripts during its first bootup: an update script *update.sh* that does basic updating and installation of some useful tools, as well as *build.sh* that builds (but does **not** install) VPP in the VM. You can view these scripts on your own for more detail on the commands used. - - -Looking further in the :ref:`vppVagrantfile`, you can see more Ruby variables being set to ENV's or to a default value: - -.. code-block:: ruby - - # Define some physical ports for your VMs to be used by DPDK - nics = (ENV['VPP_VAGRANT_NICS'] || "2").to_i(10) - for i in 1..nics - config.vm.network "private_network", type: "dhcp" - end - - # use http proxy if available - if ENV['http_proxy'] && Vagrant.has_plugin?("vagrant-proxyconf") - config.proxy.http = ENV['http_proxy'] - config.proxy.https = ENV['https_proxy'] - config.proxy.no_proxy = "localhost,127.0.0.1" - end - - vmcpu=(ENV['VPP_VAGRANT_VMCPU'] || 2) - vmram=(ENV['VPP_VAGRANT_VMRAM'] || 4096) - - -You can see how the box or VM is configured, such as the amount of NICs (defaults to 3 NICs: 1 x NAT - host access and 2 x VPP DPDK enabled), CPUs (defaults to 2), and RAM (defaults to 4096 MB). - - -Box bootup -__________ - - -Once you're satisfied with your *Vagrantfile*, boot the box with: - -.. code-block:: shell - - $ vagrant up - -Doing this above command will take quite some time, since you are installing a VM and building VPP. Take a break and get some scooby snacks while you wait. - -To confirm it is up, show the status and information of Vagrant boxes with: - -.. code-block:: console - - $ vagrant global-status - id name provider state directory - ----------------------------------------------------------------------------------------- - d90a17b default virtualbox poweroff /home/centos/andrew-vpp/vppsb/vpp-userdemo - 77b085e default virtualbox poweroff /home/centos/andrew-vpp/vppsb2/vpp-userdemo - c1c8952 default virtualbox poweroff /home/centos/andrew-vpp/testingVPPSB/extras/vagrant - c199140 default virtualbox running /home/centos/andrew-vpp/vppsb3/vpp-userdemo - - You will have only one machine running, but I have multiple as shown above. - -.. note:: - - To poweroff your VM, type: - - .. code-block:: shell - - $ vagrant halt <id> - - To resume your VM, type: - - .. code-block:: shell - - $ vagrant resume <id> - - To destroy your VM, type: - - .. code-block:: shell - - $ vagrant destroy <id> - - Note that "destroying" a VM does not erase the box, but rather destroys all resources allocated for that VM.

Then, proceed with master initialization -as described in the [kubeadm manual][3]. Execute the following command as -root: -``` -kubeadm init --token-ttl 0 --pod-network-cidr=10.1.0.0/16 -``` -**Note:** `kubeadm init` will autodetect the network interface to advertise -the master on as the interface with the default gateway. If you want to use a -different interface (i.e. a custom management network setup), specify the -`--apiserver-advertise-address=<ip-address>` argument to kubeadm init. For -example: -``` -kubeadm init --token-ttl 0 --pod-network-cidr=10.1.0.0/16 --apiserver-advertise-address=192.168.56.106 -``` -**Note:** The CIDR specified with the flag `--pod-network-cidr` is used by -kube-proxy, and it **must include** the `PodSubnetCIDR` from the `IPAMConfig` -section in the Contiv-vpp config map in Contiv-vpp's deployment file -[contiv-vpp.yaml](https://github.com/contiv/vpp/blob/master/k8s/contiv-vpp/values.yaml). Pods in the host network namespace -are a special case; they share their respective interfaces and IP addresses with -the host. For proxying to work properly it is therefore required for services -with backends running on the host to also **include the node management IP** -within the `--pod-network-cidr` subnet. For example, with the default -`PodSubnetCIDR=10.1.0.0/16` and `PodIfIPCIDR=10.2.1.0/24`, the subnet -`10.3.0.0/16` could be allocated for the management network and -`--pod-network-cidr` could be defined as `10.0.0.0/8`, so as to include IP -addresses of all pods in all network namespaces: -``` -kubeadm init --token-ttl 0 --pod-network-cidr=10.0.0.0/8 --apiserver-advertise-address=10.3.1.1 -``` - -If Kubernetes was initialized successfully, it prints out this message: -``` -Your Kubernetes master has initialized successfully! -``` - -After successful initialization, don't forget to set up your .kube directory -as a regular user (as instructed by `kubeadm`): -```bash -mkdir -p $HOME/.kube -sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config -sudo chown $(id -u):$(id -g) $HOME/.kube/config -``` - -### (3/4) Installing the Contiv-VPP Pod Network -If you have already used the Contiv-VPP plugin before, you may need to pull -the most recent Docker images on each node: -``` -bash <(curl -s https://raw.githubusercontent.com/contiv/vpp/master/k8s/pull-images.sh) -``` - -Install the Contiv-VPP network for your cluster as follows: - -- If you do not use the STN feature, install Contiv-vpp as follows: - ``` - kubectl apply -f https://raw.githubusercontent.com/contiv/vpp/master/k8s/contiv-vpp.yaml - ``` - -- If you use the STN feature, download the `contiv-vpp.yaml` file: - ``` - wget https://raw.githubusercontent.com/contiv/vpp/master/k8s/contiv-vpp.yaml - ``` - Then edit the STN configuration as described [here][16]. Finally, create - the Contiv-vpp deployment from the edited file: - ``` - kubectl apply -f ./contiv-vpp.yaml - ``` - -Beware contiv-etcd data is persisted in `/var/etcd` by default.

For +now, this feature must be either disabled or memory limit must be +defined for vswitch container. + +To disable huge pages, perform the following steps as root: \* Using +your favorite editor, disable huge pages in the kubelet configuration +file (``/etc/systemd/system/kubelet.service.d/10-kubeadm.conf`` or +``/etc/default/kubelet`` for version 1.11+): + +:: + + Environment="KUBELET_EXTRA_ARGS=--feature-gates HugePages=false" + +- Restart the kubelet daemon: + +:: + + systemctl daemon-reload + systemctl restart kubelet + +To define memory limit, append the following snippet to vswitch +container in deployment yaml file: + +:: + + resources: + limits: + hugepages-2Mi: 1024Mi + memory: 1024Mi + +or set ``contiv.vswitch.defineMemoryLimits`` to ``true`` in `helm +values <https://github.com/contiv/vpp/blob/master/k8s/contiv-vpp/README.md>`__. + +(2/4) Initializing Your Master +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Before initializing the master, you may want to +`remove <#tearing-down-kubernetes>`__ any previously installed K8s +components. Then, proceed with master initialization as described in the +`kubeadm +manual <https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/#initializing-your-master>`__. +Execute the following command as root: + +:: + + kubeadm init --token-ttl 0 --pod-network-cidr=10.1.0.0/16 + +**Note:** ``kubeadm init`` will autodetect the network interface to +advertise the master on as the interface with the default gateway. If +you want to use a different interface (i.e. a custom management network +setup), specify the ``--apiserver-advertise-address=<ip-address>`` +argument to kubeadm init. For example: + +:: + + kubeadm init --token-ttl 0 --pod-network-cidr=10.1.0.0/16 --apiserver-advertise-address=192.168.56.106 + +**Note:** The CIDR specified with the flag ``--pod-network-cidr`` is +used by kube-proxy, and it **must include** the ``PodSubnetCIDR`` from +the ``IPAMConfig`` section in the Contiv-vpp config map in Contiv-vpp’s +deployment file +`contiv-vpp.yaml <https://github.com/contiv/vpp/blob/master/k8s/contiv-vpp/values.yaml>`__. +Pods in the host network namespace are a special case; they share their +respective interfaces and IP addresses with the host. For proxying to +work properly it is therefore required for services with backends +running on the host to also **include the node management IP** within +the ``--pod-network-cidr`` subnet. For example, with the default +``PodSubnetCIDR=10.1.0.0/16`` and ``PodIfIPCIDR=10.2.1.0/24``, the +subnet ``10.3.0.0/16`` could be allocated for the management network and +``--pod-network-cidr`` could be defined as ``10.0.0.0/8``, so as to +include IP addresses of all pods in all network namespaces: + +:: + + kubeadm init --token-ttl 0 --pod-network-cidr=10.0.0.0/8 --apiserver-advertise-address=10.3.1.1 + +If Kubernetes was initialized successfully, it prints out this message: + +:: + + Your Kubernetes master has initialized successfully! + +After successful initialization, don’t forget to set up your .kube +directory as a regular user (as instructed by ``kubeadm``): + +.. code:: bash + + mkdir -p $HOME/.kube + sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config + sudo chown $(id -u):$(id -g) $HOME/.kube/config + +(3/4) Installing the Contiv-VPP Pod Network +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you have already used the Contiv-VPP plugin before, you may need to +pull the most recent Docker images on each node: + +:: + + bash <(curl -s https://raw.githubusercontent.com/contiv/vpp/master/k8s/pull-images.sh) + +Install the Contiv-VPP network for your cluster as follows: + +- If you do not use the STN feature, install Contiv-vpp as follows: + + :: + + kubectl apply -f https://raw.githubusercontent.com/contiv/vpp/master/k8s/contiv-vpp.yaml + +- If you use the STN feature, download the ``contiv-vpp.yaml`` file: + + :: + + wget https://raw.githubusercontent.com/contiv/vpp/master/k8s/contiv-vpp.yaml + + Then edit the STN configuration as described + `here <https://github.com/contiv/vpp/tree/master/docs/SINGLE_NIC_SETUP.md#configuring-stn-in-contiv-vpp-k8s-deployment-files>`__. + Finally, create the Contiv-vpp deployment from the edited file: + + :: + + kubectl apply -f ./contiv-vpp.yaml + +Beware contiv-etcd data is persisted in ``/var/etcd`` by default.

The bridge domain -has learning and flooding disabled, the l2fib of the bridge domain contains a static entry for each VXLAN tunnel. Each bridge domain has a BVI interface, which -interconnects the bridge domain with the main VRF (L3 forwarding). This interface needs -a unique IP address, which is assigned from the `VxlanCIDR` as describe above. - -The main VRF contains several static routes that point to the BVI IP addresses of other nodes. -For each node, it is a route to PODSubnet and VppHostSubnet of the remote node, as well as a route -to the management IP address of the remote node. For each of these routes, the next hop IP is the -BVI interface IP of the remote node, which goes via the BVI interface of the local node. - -The VXLAN tunnels and the static routes pointing to them are added/deleted on each VPP, -whenever a node is added/deleted in the k8s cluster. - - -#### More Info -Please refer to the \[Packet Flow Dev Guide\](../dev-guide/PACKET_FLOW.html) for more -detailed description of paths traversed by request and response packets -inside Contiv/VPP Kubernetes cluster under different situations.

The TAP interface is configured with IP +addresses from the ``VPPHostSubnetCIDR`` range, with ``.1`` in the +latest octet on the VPP side, and ``.2`` on the host side. The name of +the host interface is ``vpp1``. The host has static routes pointing to +VPP configured with: - A route to the whole ``PodSubnetCIDR`` to route +traffic targeting PODs towards VPP. - A route to ``ServiceCIDR`` +(default ``10.96.0.0/12``), to route service IP targeted traffic that +has not been translated by kube-proxy for some reason towards VPP. - The +host also has a static ARP entry configured for the IP of the VPP-end +TAP interface, to get rid of unnecessary broadcasts between the main +network namespace and VPP. + +VXLANs to Other Nodes +~~~~~~~~~~~~~~~~~~~~~ + +In order to provide inter-node POD to POD connectivity via any underlay +network (not necessarily an L2 network), Contiv/VPP sets up a VXLAN +tunnel overlay between each 2 nodes within the cluster (full mesh). + +All VXLAN tunnels are terminated in one bridge domain on each VPP. The +bridge domain has learning and flooding disabled, the l2fib of the +bridge domain contains a static entry for each VXLAN tunnel. Each bridge +domain has a BVI interface, which interconnects the bridge domain with +the main VRF (L3 forwarding). This interface needs a unique IP address, +which is assigned from the ``VxlanCIDR`` as describe above. + +The main VRF contains several static routes that point to the BVI IP +addresses of other nodes. For each node, it is a route to PODSubnet and +VppHostSubnet of the remote node, as well as a route to the management +IP address of the remote node. For each of these routes, the next hop IP +is the BVI interface IP of the remote node, which goes via the BVI +interface of the local node. + +The VXLAN tunnels and the static routes pointing to them are +added/deleted on each VPP, whenever a node is added/deleted in the k8s +cluster. + +More Info +~~~~~~~~~ + +Please refer to the [Packet Flow Dev +Guide](../dev-guide/PACKET_FLOW.html) for more detailed description of +paths traversed by request and response packets inside Contiv/VPP +Kubernetes cluster under different situations. diff --git a/docs/usecases/contiv/Prometheus.md b/docs/usecases/contiv/Prometheus.md deleted file mode 100644 index ba61be3c739..00000000000 --- a/docs/usecases/contiv/Prometheus.md +++ /dev/null @@ -1,159 +0,0 @@ -# Prometheus Statistics - -Each contiv-agent exposes statistics in Prometheus format at port `9999` by default. -Exposed data is split into two groups: -- `/stats` provides statistics for VPP interfaces managed by contiv-agent - Prometheus data is a set of counters with labels.

The user has to manually clear the buffer +content, and then repeat the trace command to resume the packet capture, +losing information about all packets received in the meantime. + +Packet filtering exposed via the CLI command ``trace filter`` is also +quite limited in what it can do. Currently there is just one available +filter, which allows you to keep only packets that include a certain +node in the trace or exclude a certain node in the trace. It is not +possible to filter the traffic by its content (e.g., by the +source/destination IP address, protocol, etc.). + +Last but not least, it is not possible to trace packets on a selected +interface like ``tcpdump``, which allows tracing via the option ``-i``. +VPP is only able to capture packets on the *RX side* of selected +*devices* (e.g., dpdk, virtio, af-packet). This means that interfaces +based on the same device cannot be traced for incoming packets +individually, but only all at the same time. In Contiv/VPP all pods are +connected with VPP via the same kind of the TAP interface, meaning that +it is not possible to capture packets incoming only from one selected +pod. + +Contiv/VPP ships with a simple bash script +`vpptrace.sh <https://github.com/contiv/vpp/blob/master/scripts/vpptrace.sh>`__, +which helps alleviate the aforementioned VPP limitations. The script +automatically re-initializes buffers and traces whenever it is close to +getting full, in order to avoid packet loss as much as possible. Next it +allows you to filter packets by the content of the trace. There are two +modes of filtering: - *substring mode* (default): packet trace must +contain a given sub-string in order to be included in the output - +*regex mode*: packet trace must match a given regex in order to be +printed + +The script is still limited, in that capture runs only on the RX side of +all interfaces that are built on top of selected devices. Using +filtering, however, it is possible to limit *traffic by interface* +simply by using the interface name as a substring to match against. + +Usage +----- + +Run the script with option ``-h`` to get the usage printed: + +:: + + Usage: ./vpptrace.sh [-i <VPP-IF-TYPE>]...

-The VPP network stack comes equipped with a set of commands that are useful -for debugging. - -The easiest way to access the CLI (with proper permissions) is to use the -vppctl command: - -``` -sudo vppctl <cli-command> -``` - -The CLI parser matches static keyword strings, eventually invoking an action -function. Unambiguous partial keyword matching always occurs. The action -functions consume input until satisfied or until they fail. This model makes -for easy coding, but does not guarantee useful "help" output. It's up to the -CLI command writer to add useful help strings. - -You can find the source code of CLI commands by searching for instances of the -@c VLIB_CLI_COMMAND macro in the code source files. - -Please help maintain and improve this document to make and keep these commands -clear and useful! - -@todo Document where to modify this CLI intro text. - - -## Debug and Telnet CLI - -The debug CLI is enabled with the unix interactive parameter or startup -configuration option. This causes VPP to start without daemonizing and -presents a command line interface on the terminal where it is run. - -The Telnet CLI is enabled with the `cli-listen localhost:5002` option which -will cause VPP to listen for TCP connections on the localhost address port -@c 5002. A Telnet client can then connect to this port (for example, `telnet -localhost 5002`) and will receive a command line prompt. - -This configuration will enable both mechanisms: - -``` -unix { - interactive - cli-listen localhost:5002 -} -``` - -The debug CLI can operate in line mode, which may be useful when running -inside an IDE like Emacs. This is enabled with the option -`unix cli-line-mode`. Several other options exist that alter how this -CLI works, see the @ref syscfg section for details. - -The CLI starts with a banner graphic (which can be disabled) and a prompt. The -prompt will typically read `vpp` for a release version of VPP and `DBGvpp#` -for a development version with debugging enabled, for example: - - _______ _ _ _____ ___ - __/ __/ _ \ (_)__ | | / / _ \/ _ \ - _/ _// // / / / _ \ | |/ / ___/ ___/ - /_/ /____(_)_/\___/ |___/_/ /_/ - - vpp# - -versus: - - _______ _ _ _____ ___ - __/ __/ _ \ (_)__ | | / / _ \/ _ \ - _/ _// // / / / _ \ | |/ / ___/ ___/ - /_/ /____(_)_/\___/ |___/_/ /_/ - - DBGvpp# - -This prompt can be configured with the `unix cli-prompt` setting and the -banner is disabled with `unix cli-no-banner`. - -## CLI features - -The CLI has several editing features that make it easy to use. - -- Cursor keys left/right will move the cursor within a command line; - typing will insert at the cursor; erase will erase at the cursor. - -- Ctrl-left/right will search for the start of the next word to - the left or right. -- Home/end will jump the cursor to the start and end of the line. -- Cursor keys up/down and ^P/^N iterate through the command history - buffer. Lines from the history buffer may be edited. New commands - are added to the end of the buffer when executed; though - duplicates of the previous command are not added. -- ^U erases the line contents from the left of the cursor to the - start. -- ^K erases the contents from the cursor to the end. -- ^S/^R will search the command history forwards or in reverse for - a command; start typing for matches to auto complete. -- ^L will clear the screen (if supported by the terminal) and repaint - the prompt and any current line. The cursor position is also - retained. -- The CLI can be closed with the quit command. Alternatively, ^D on - an empty input line will also close the session. Closing the debug - session will also shutdown VPP. - -Output that exceeds the length of a terminal page will be buffered, up to a -limit. - -- Space or page-down displays the next page. -- Enter or down-arrow displays the next line. -- Page-up goes back a page. -- Up-arrow goes up a line. -- Home/end jump to the start/end of the buffered output. -- The key q quits the pager.
