[libc] Move libc_errno.h to libc/src/__support and make LIBC_ERRNO_MODE_SYSTEM to be header-only. (#143187)

2025-06-11T20:25:27+00:00

This is the first step in preparation for:

[libc] Fix sendmsg iovec unpoisoning (#115057)

2024-11-05T21:34:57+00:00

The unpoisoning for sendmsg had a typo where it would not unpoison all
of the elements in the iovec, causing msan errors. This patch fixes
that.

[libc] Small recvfrom fixes (yaml, unpoison) (#111020)

2024-10-03T22:11:04+00:00

Forgot to update the newhdrgen yaml (old headergen is fine) and forgot
to unpoison addrlen. This patch fixes those.

[libc] Fix send and recv functions (#110936)

2024-10-03T16:42:15+00:00

There were some errors in the implementation. Oops. This patch fixes
those.

[libc] Add MSAN unpoison annotations to recv funcs (#109844)

2024-09-24T21:54:02+00:00

Anywhere a struct is returned from the kernel, we need to explicitly
unpoison it for MSAN. This patch does that for the recv, recvfrom,
recvmsg, and socketpair functions.

[libc] Add functions to send/recv messages (#106467)

2024-09-19T21:43:00+00:00

This patch adds the necessary functions to send and receive messages
over a socket. Those functions are: recv, recvfrom, recvmsg, send,
sendto, sendmsg, and socketpair for testing.
