2023-08-09session: async rx event notificationsFlorin Coras23-629/+949
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.

2023-08-08vcl: Fix the ldp init checkGao Feng1-1/+5
Maybe some function calls the wrapper funtion like read which invokes the ldp_init_check in the other libs as a constructor before ldp_constructor. Then the ldp has been initialized already when ldp_constructor is invoked. And it's normal case, we shouldn't treat it as an error. So ldp_init should return success if ldp is initialized already instead of an assert. Type: fix Change-Id: Ifa2a7b1d5471981a3f840b14a4fa5d48fb1f1374 Signed-off-by: Gao Feng <gfree.wind@outlook.com>

2023-08-07vcl: fix error state switch for VCL_STATE_LISTEN_NO_MQ sessionswanghanlin1-3/+4
When a VCL_STATE_LISTEN_NO_MQ session receives an ACCEPTED message, but then receives either a RESET or DISCONNECTED message from VPP before the session is unlistened, the listen session state is switched to DISCONNECT. The subsequent CLEANUP message handler attempts to send a reset reply message to VPP, but since the vpp_evt_q for the listen session is null, this leads to a crash.

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).
