2022-08-18nat: Replace port refcounts with simple bitvectorsJon Loeliger2-17/+80
Previously, each address maintained an array of 32-bit reference counts for each of 65K possible ports for each of 4 NAT protocols. Totalling 1MB per address. Wow. A close read of the code shows that an "is used" check precedes each attempted reference count increment. That means the refcount never actually gets above 1. That in turn means algorithmically, a bit vector is sufficient. And one need not be allocated for more than the highest validated port referenced. These changes introduce a dynamically sized bit vector replacing the reference counts, for a maximum of 32K if all 4 protocols use port 65535. In fact, protocol OTHER is never used, so at most 24K will be used, and none of it will be "statically" allocated per address.

2022-08-16nat: fix potential out-of-bound worker array indexJing Peng3-24/+36
In several NAT submodules, the number of available ports (0xffff - 1024) may not be divisible by the number of workers, so port_per_thread is determined by integer division, which is the floor of the quotient. Later when a worker index is needed, dividing the port with port_per_thread may yield an out-of-bound array index into the workers array. As an example, assume 2 workers are configured, then port_per_thread will be (0xffff - 1024) / 2, which is 32255. When we compute a worker index with port 0xffff, we get (0xffff - 1024) / 32255, which is 2, but since we only have 2 workers, only 0 and 1 are valid indices. This patch fixes the problem by adding a modulo at the end of the division. Type: fix Signed-off-by: Jing Peng <pj.hades@gmail.com> Change-Id: Ieae3d5faf716410422610484a68222f1c957f3f8
2022-05-31nat: disable nat44-ei-in2out-output ttl checkAlexander Skorichenko1-3/+3
Type: fix A packet passing through nat44-ei-in2out-output, has its ttl value validated in earlier nodes. "ip4-input" node checks ttl for locally generated packets. "ip4-rewrite" node validates ttl in forwarded packets. Thus for example, the ED counterpart disables ttl checks in its "nat44-ed-in2out-output" node. This patch updates nat44 EI conditions for ttl checks to those currently used in nat44 ED case, meaning no extra ttl validation for in2out when output-feature is enabled.

2022-05-10tests: replace pycodestyle with blackKlement Sekera14-229/+315
Drop pycodestyle for code style checking in favor of black. Black is much faster, stable PEP8 compliant code style checker offering also automatic formatting. It aims to be very stable and produce smallest diffs. It's used by many small and big projects. Running checkstyle with black takes a few seconds with a terse output. Thus, test-checkstyle-diff is no longer necessary. Expand scope of checkstyle to all python files in the repo, replacing test-checkstyle with checkstyle-python. Also, fixstyle-python is now available for automatic style formatting. Note: python virtualenv has been consolidated in test/Makefile, test/requirements*.txt which will eventually be moved to a central location. This is required to simply the automated generation of docker executor images in the CI.

2022-04-21nat: tweak rfc7857 tcp connection trackingOle Troan4-292/+61
The RFC7857 state machine introduced in 56c492a is a trade-off. It tries to retain sessions as much as possible and also offers some protection against spurious RST by re-establishing sessions if data is received after the RST. From experience in the wild, this algorithm is a little too liberal, as it leaves too many spurious established sessions in the session table. E.g. a oberserved pattern is: client server <- FIN, ACK ACK -> ACK -> RST, ACK -> With the current state machine this would leave the session in established state. These proposed changes do: - require 3-way handshake to establish session. (current requires only to see SYNs from both sides) - RST will move session to transitory without recovery if data is sent after - Only a single FIN is needed to move to transitory Fixes: 56c492aa0502751de2dd9d890096a82c5f04776d Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I92e593e00b2efe48d04997642d85bd59e0eaa2ea Signed-off-by: Ole Troan <ot@cisco.com>

If "nat44 add interface address" command would fail the vlib cli processing function would call "nat44" handler. This would also clean any previously set errors from the first command and basically return same error returned by "nat44" handler for every failed command that starts with the same path string.

This patch affects how destination fib is choosen during session creation. Default behavior of choosing fib based on output interfaces is kept. Configuration gives you the ability to change default behavior to direct or restrict traffic between different FIB tables. NAT specific VRF routing options: a) keeping communication in the same VRF b) option to add multiple destination VRFs c) option to control the resolution order of destination VRFs TX FIB resolution is based on looking up RX FIB entry in NATs VRF table and picking the first FIB that resolves destination address.

Implement proper state machine based on above RFCs. ACKs to SYNs/FINs are no longer required/tracked. This is more friendly to peers and accounts for lost packets and retransmits. This change also means that all traffic is translated and forwarded while in transitory timeout, which helps delivering e.g. retransmitted FINs, FINACKs and other messages. Also support reopening a session in transitory timeout after seeing both FINs by seeing both SYNs again. This helps quick connection reestablishment if the peers want to.

2022-01-04nat: remove nat44-ed relation between SM and addrFilip Varga6-555/+436
Change [1] put static mappings in flow hash. This change also broke relationship between nat pool addresses and static mappings. Port and address are no longer reserved in nat pool address records for a new static mapping. Because of this change both nat objects and their configuration can function independently. This change also removed already broken logic of having static-mapping-only configuration. In this patch i have cleaned up and removed unnecessary logic for static mapping configuration functions, address configuration functions, interface configuraiton functions and all callback functions used for resolving interface address bound records. No more viable configuration option static-mapping-only is also removed because there is no more option to run traffic through vpp for static mappings without having flow hash table allocated. Instead user is now able to create static mapping records without using nat pool addresses. Fixed and improved management of required fib entries (ensuring VPP will reply to ARP for all external addresses on outside interfaces) through holding a refcount for their creation and removal.

2021-11-22ipfix-export: refactor params to the callback fnsPaul Atkins1-31/+16

2021-11-22ipfix-export: refactor fields in flow_report_mainPaul Atkins1-23/+30
Pull out the fields in flow_report_main_t that are specific to a single exporter and move them into a new structure that represents an exporter. Add a pool of exporters to flow_report_main_t and do a pool_get() to get the entry at index 0, so that the existing users of the code need only change the path at which they access the old fields and have no need to make further code changes. In functions that were accessing the fields that now make up the ipfix_exporter create a local var that points to the first (always valid) exporter and use this as the base for the fields rather than finding them from flow_report_main. This is in preparation for supporting multiple flow_exporters. Note that at the moment the code supports multiple 'streams' for a given exporter, where each stream has its own source port, domain id and template space. But all streams within an exporter have the same destination address, so this is not the same as multiple exporters.
