https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D222039 --- Comment #1 from commit-hook@freebsd.org --- A commit references this bug: Author: sobomax Date: Thu Sep 7 04:29:57 UTC 2017 New revision: 323254 URL: https://svnweb.freebsd.org/changeset/base/323254 Log: In the recvmsg32() system call iterate over returned structure(s) and convert any messages of types SCM_BINTIME, SCM_TIMESTAMP, SCM_REALTIME and SCM_MONOTONIC from 64-bit to its 32-bit representation. Otherwise we either run out of user-supplied buffer to copy those out resulting in the MSG_CTRUNC or simply return values that the userland 32-bit code is not going to parse correctly. This fixes at least two regression tests failing to function properly in 32-bit compat mode: tools/regression/sockets/udp_pingpong tools/regression/sockets/unix_cmsg PR: kern/222039 MFC after: 30 days Changes: head/sys/compat/freebsd32/freebsd32.h head/sys/compat/freebsd32/freebsd32_misc.c --=20 You are receiving this mail because: You are the assignee for the bug.=
