https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227259 Bug ID: 227259 Summary: accept() does not wakeup on shutdown()/close() Product: Base System Version: 11.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: rozhuk.im@gmail.com Attachment #192171 text/plain mime type: Created attachment 192171 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D192171&action= =3Dedit acc_test.c We have some legacy app that create socket, create thread and in new thread call accept() with this socket. Main thread wait for signals and do shutdown() + close() for socket, then w= ait until accept thread wakeup and exit, then app exit/create new socket+thread. On FreeBSD 9, 10 - OK. On FreeBSD 11 - thread does not wakeup on shutdown() and close().
