2023-01-12misc: use right include for fctnl.h and poll.hGuillaume Solignac1-2/+2
Musl is stricter than glibc and has a warning that including fctnl.h and poll.h should be prefered rather than their sys/ counterparts, which breaks -Wall setups. Type: fix Signed-off-by: Guillaume Solignac <gsoligna@cisco.com> Change-Id: Id101e999371951b0927cc8c4109f8f1536de1bc2

Some upon apps(e.g. Nginx-quic) package it's several protocol buffers into a struct msg which is a combination of gso_buffer and gso_size. but if HostStack regardless the gso_size to the buffer and split the buffer with default mss, that cause peer client failed on parsing the package.

2022-07-20vcl: new vcl api to get detailed session errorsRadha krishna Saragadam1-0/+8
Sometimes VPP rejects application connection requests due to various reasons. Some errors application can retry to get a successful connection. In a non-blocking session, VCL sends EPOLLHUP. An application can call a new API vppcom_session_get_error to find the details and retry depending on the error.

2020-05-04vcl: allow vcl worker index to be set by applicationsPivo1-0/+5
When using vppcom_session* apis to setup TCP sessions in applications build outside of the VPP repository, it is necessary to set the worker_index explicitly when these apis are called from the none-VCL worker threads. An example is when data is to be sent to the TCP session that is originated from a different thread, like the main program thread or from the bin api thread. This change allows the application to set it. Type: fix Signed-off-by: IJsbrand Wijnands <ice@cisco.com> Change-Id: I37f3654a49ea9a8cf3a0d3d0e672583018c12299

- support eventfd based mq signaling.

Have vcl poll and wait on the event message queues as opposed to constantly polling the session fifos. This also adds event signaling to cut through sessions. On the downside, because we can't wait on multiple condvars, i.e., when we have multiple message queues because of cut-through registrations, we do timed waits.
