socket tests: Clean up the MSG_TRUNC regression tests a bit2023-10-24T13:18:27ZMark Johnstonmarkj@FreeBSD.org2023-10-16T21:35:07Zurn:sha1:95fa4ae00e18a46eb85e31718d172b12ba2d2ce4
- Fix style.
- Move test case-specific code out of the shared function and into the
individual test cases.
- Remove unneeded setting of SO_REUSEPORT.
- Avoid unnecessary copying.
- Use ATF_REQUIRE* instead of ATF_CHECK*. The former cause test
execution to stop after a failed assertion, which is what we want.
- Add a test case for AF_LOCAL/SOCK_SEQPACKET sockets.

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

sockets: add MSG_TRUNC flag handling for recvfrom()/recvmsg().2023-02-09T18:01:49ZAlexander V. Chernikovmelifaro@FreeBSD.org2022-07-25T19:46:40Zurn:sha1:adaf752192c165b66875e81db62d274a09591d0c
Implement Linux-variant of MSG_TRUNC input flag used in recv(), recvfrom() and recvmsg().
Posix defines MSG_TRUNC as an output flag, indicating packet/datagram truncation.
Linux extended it a while (~15+ years) ago to act as input flag,
resulting in returning the full packet size regarless of the input
buffer size.
It's a (relatively) popular pattern to do recvmsg( MSG_PEEK | MSG_TRUNC) to get the
packet size, allocate the buffer and issue another call to fetch the packet.
In particular, it's popular in userland netlink code, which is the primary driving factor of this change.
This commit implements the MSG_TRUNC support for SOCK_DGRAM sockets (udp, unix and all soreceive_generic() users).
