tty: Avoid leaving dangling pointers in tty_drop_ctty()

2026-04-21T15:43:53Z

The TIOCNOTTY handler detaches the calling process from its controlling terminal. It clears the link from the session to the tty, but not the pointers from the tty to the session and process group. This means that sess_release() doesn't call tty_rel_sess(), and that pgdelete() doesn't call tty_rel_pgrp(), so the pointers are left dangling. Fix this by clearing pointers in tty_drop_ctty(). Add a standalone regression test.

kern: pts: do not special case closed slave side

2024-01-30T17:11:10Z

This would previously return 1 if the slave side of the pts was closed to force an application to read() from it and observe the EOF, but it's not clear why and this is inconsistent both with how we handle devices with similar mechanics (like pipes) and also with other kernels, such as OpenBSD/NetBSD and Linux.

sockets: add MSG_TRUNC flag handling for recvfrom()/recvmsg().

2023-02-09T18:01:49Z

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).
