The branch stable/14 has been updated by glebius: URL: https://cgit.FreeBSD.org/src/commit/?id=ac84975e4a1f89a608a3c6ba8f8322b19a83421e commit ac84975e4a1f89a608a3c6ba8f8322b19a83421e Author: Gleb Smirnoff <glebius@FreeBSD.org> AuthorDate: 2023-12-01 23:37:29 +0000 Commit: Gleb Smirnoff <glebius@FreeBSD.org> CommitDate: 2024-01-09 00:26:38 +0000 unix/dgram: bump maximum datagram size limit to 8k This is important for wpa_supplicant operation on a crowded network. Note: we actually need an API to increase maximum datagram size on a socket. Previously SO_SNDBUF magically acted like that, but that was an undocumented "feature". Also move the comment to the proper line. Previously it was the receive buffer that imposed the limit. Now notion of buffer size and maximum datagram are separate.
