But the failures in the current issue *all* involve FD passing :) The "Message too long" errors are in tests where the ancillary data (in this case file descriptors) is truncated, rather than the normal data, so msg_iovlen shouldn't be a problem there (and MSG_CTRUNC would normally be set, rather than MSG_TRUNC). I suppose the most likely reason for a process to be sent too many file descriptors is that someone is attempting a denial-of-service attack on it, so perhaps returning EMSGSIZE is intended as a "fail safe" response, even if it isn't blessed by POSIX? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20669> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
