2023-08-31fateshare: a plugin for managing child processesAndrew Yourtchenko4-0/+621
For the reasons of modularity and security, it is useful to have various functionality split into processes different from VPP. However, this approach presents the challenges of managing those processes, and is markedly different from simply running everything within VPP process. This plugin is an experiment in having the VPP itself start off a monitor process which in turn starts the child processes, and restarts them if they quit. If the VPP process ceases to exist, the monitor process terminates all the descendant processes and quits itself. This allows to preserve the "single entity to manage" approach of simply running a barebones VPP. An example of running it: export DPDK_CONFIG="" export DISABLED_PLUGINS=dpdk export EXTRA_VPP_CONFIG="fateshare { monitor ./build-root/install-vpp_debug-native/vpp/bin/vpp_fateshare_monitor command ./test1 }" make run Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> Change-Id: I66221fd7403f220d9652fe76958ca499cfd070a7 Type: feature

2023-08-09session: async rx event notificationsFlorin Coras6-17/+82
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

2023-08-07cnat: Support offloaded check sumsNathan Skrzypczak4-215/+155
This patch removes zero checks for new_addr, new_port meaning sessions with zero values will rewrite the packet with a 0 value instead of leaving it in place. This allows to reduce branchiness in the code, and sessions are fully resolved at creation time anyway. This also adds support for checksum offloads: - IP checksum offload : we always compute the checksum to avoid issues with drivers. We'll revert this if we realize cost gets too important. - TCP/UDP checksum offload : we add the implementation for pseudo header checksum computation. This is needed for the drivers that do not re-compute this pseudo-checksum before the packet is TX-ed (e.g. a few DPDK drivers).

2023-07-13lb: Fix src_ip_sticky evaluation bug in per-port-vip case.Nobuhiro MIKI3-469/+74
Before this fix, the src_ip_sticky flag was passed as an argument to the lb_node_get_hash function, which computes a hash value for a packet. However, in per-port-vip case, the value of src_ip_sticky flag may be different for each port number. As a result, the value is the same for all port numbers, even though it is a per-port-vip case. This commit fixes the src_ip_sticky evaluation by delaying it until the packet is received, so that the correct value is obtained. Also, the unit test case has been enhanced for this bug fix.

2023-07-12linux-cp: fix crash on processing dump of routesAlexander Chernavin1-3/+10
nl_route_add() recently started to use its optional argument to check whether replace flag is set for the message. When notification messages are processed, the argument is a pointer to the corresponding message info. However, when dump replies are processed, the argument is a null pointer. This leads to null pointer dereference and crash when dump of routes is processed. With this fix, check for replace flag only if message info was passed to nl_route_add(). Otherwise, assume the flag is not set. Dump replies do not have it set. Type: fix Change-Id: Icb04a1146e09cc965b623018c28f91b347be0eab Signed-off-by: Alexander Chernavin <achernavin@netgate.com>

2023-07-11linux-cp: Basic MPLS support.Adrian Pistol5-11/+419
1) Imports ENCAP_MPLS labels from IPv4/IPv6 routes. Note that this requires libnl 3.6.0 or newer. In previous patches, the fib_path_ext_t had a path ID of -1. After a long investigation, it turned out to be caused by route weight being set to 0. There is a comment explaining more details. 2) Handles MPLS routes. MPLS routes were wrongly added as IPv4 routes before. POP and SWAP are now both supported. All the routes are installed as NON-EOS and EOS routes, as the Linux kernel does not differentiate. EOS POP used in PHP uses the next-hop address family to determine the resulting address family. This patch is sufficient for P setups. PE setups with implicit null should also function okay, as long as a seperate label gets programmed per address family. PE setups with explicit null will also forward packets, but punting is a bit odd and needs MPLS input enabled on the LCP host device. 3) Propagate MPLS input state to LCP Pair and Linux. Since the Linux kernel uses the MPLS routes itself, the LCP pair tap needs MPLS enabled to allow host originated packets. This also syncs the Linux `net.mpls.conf.<host_if>.input` sysctl to allow punted packets to have MPLS labels, mostly explicit nulls. In addition, a special feature is enabled to cross connect MPLS packets coming from Linux directly to interface-output untouched. Make sure to enable MPLS/add a table in VPP first and load the MPLS kernel modules!!

2023-06-08crypto: use fixed crypto frame poolgaoginskx2-0/+4
The async frames pool may be resized once drained. This will cause 2 problems: original pool pointer is invalidated and pool size changed, both problems will confuse the crypto infra user graph nodes (like IPsec and Wireguard) and crypto engines if they expect the pool pointers always valid and the pool size never changed (for performance reason). This patch introduces fixed size of the async frames pool. This helps zeroing surprise to the components shown above and avoiding segmentation fault when pool resizing happened. In addition, the crypto engine may take advantage of the feature to sync its own pool/vector with crypto infra.
