2023-03-06vppinfra: display only the 1st 50 memory traces by defaultBenoît Ganne2-3/+5
When using memory traces it can take a long time to display all traces bigger than 1k if there are lots of them, especially as we need to resolve symbols. It is better to display only the 1st 50 by default, unless verbose is used. Also fix the help string.

2023-03-06memif: autogenerate socket_idsNathan Skrzypczak5-0/+181
This patch adds an API memif_socket_filename_add_del_v2 that allows autogenerating memif socket_id when passing ~0 in the socket_id field. It opportunistically walks the hash to find a free ID to use, and returns it in the reply. socket_filename also becomes a variable length string, to accomodate for longer names (in case a netns gets passed) Type: feature Change-Id: I33fc3e1cf553af27579d6bad8691b22b530531cc Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
2023-03-02wireguard: add barrier to sync dataGabriel Oginski6-32/+43
The current implmentation of the hash table is not thread-safe. This design leads to a segfault when VPP is handling a lot of tunnels for Wireguard, where one thread modifies the hash table and other threads start the lookup at the same time. This fix adds a barrier sync to the hash table access when Wireguard adds or deletes an element.

2023-02-27wireguard: fix potential leaks of async frameGabriel Oginski1-12/+12
The current implementation can cause memory leaks of async frames and exhaust the async frames pool. Wireguard can early get async frame, even when later it turns out it is not needed. Then such frame won't be freed. This fix changes the moment of acquiring async frame from the pool, so it doesn't leak.

2023-02-16vcl: fix incorrect ldp worker in ldp_epoll_pwait()Liangxing Wang1-1/+5
For some apps(e.g. wrk2) upon vpp hoststack, ldp_epoll_pwait() is called. In this function, epoll fd was created on one thread, but it is now used on another thread. The vcl worker index is still invalid, so the fetched ldp worker is also invalid and can corrupt some already allocated memory. Just as the ldp_epoll_pwait_eventfd(), make sure the vcl worker is valid before getting the ldp worker in ldp_epoll_pwait().

2023-02-13rdma: always use 64 byte CQEs for MLX5Nathan Brown1-5/+23
When DPDK MLX PMDs are built, and the DPDK plugin is loaded, DPDK may set the MLX5_CQE_SIZE environment variable to 128. This causes the RDMA plugin to be unable to create completion queues. Since the RDMA plugin expects the CQEs to be 64 bytes, set the cqe_size explicitly when creating the CQ. This avoids any issues with different values for the MLX5_CQE_SIZE environment variable.

2023-02-03nat: fix accidental o2i deletion/reuseDmitry Valter1-0/+6
Nat session is allocated before the port allocation. During port allocation candidate address+port are set to o2i 6-tuple and tested against the flow hash. If insertion fails, the port is busy and rejected. When all N attempts are unsuccessful, "out-of-ports" error is recorded and the session is to be deleted. During session deletion o2i and i2o tuples are deleted from the flow hash. In case of "out-of-ports" i2o tuple is not valid, however o2i is and it refers to **some other** session that's known to be allocated. By backing match tuple up session should be invalidated well enough not to collide with any valid one.

2023-02-02tls: openssl: fix SSL_read partial read scenarioOfer Heifetz1-8/+10
When application performs SSL_read from the app rx-fifo, it can pre-allocate multiple segments, but there is an issue if the OpenSSL manages to partially fill in the first segment, in this case, since data is assumed to be copied over by OpenSSL to the pre-allocated segments(s), vpp uses svm_fifo_enqueue_nocopy API which performs zero copy by passing the pre-allocated segment to SSL_read. If the decrypted data size is smaller than the pre-allocated fifo segment buffer size, application will fetch buffers including zero in the area not filled in by SSL_read.
