I have a FreeBSD 14.2 VM that I use for testing and it wasn't failing for me.

That bug was fixed, but it seems it's still just a loop around recvmsg, not a single system call, which means there is an extra system call made and I'm not sure if it's worth it. https://github.com/freebsd/freebsd-src/blob/main/lib/libsys/recvmmsg.c#L80 -- Miroslav Lichvar -- To unsubscribe email chrony-users-requ...@chrony.tuxfamily.org with "unsubscribe" in the subject.
