Package: dovecot-imapd Version: 1:1.2.5-1 Severity: grave I run dovecot directly, without passing through a TCP socket, on my laptop to provide direct access to a mail spool in my home directory, with preauth:
/usr/sbin/dovecot --exec-mail imap This previously worked just fine, but now fails as both a privileged and unprivileged user due to epoll returning -EPERM: epoll_ctl(6, EPOLL_CTL_ADD, 0, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=9753488, u64=9753488}}) = -1 EPERM (Operation not permitted) Note that it tries the operation of FD 0, STDIN, which is attached to the shell in the interactive test, or to a pipe otherwise. mail.log contains: Sep 15 16:03:31 krosp IMAP(daniel): : Fatal: io_loop_handle_add: epoll_ctl(1, 0): Operation not permitted The only references to this I can find are historic, and suggest this was an issue elsewhere but is now fixed. I am running the stock Debian/unstable kernel, nothing special. Please find attached a full strace of the Dovecot run that fails. This is pretty serious for me, because it prevents this *documented* mode of operation from working under, as far as I can tell, any circumstances. Downgrading to the version from stable, 1.2.24-2, resolves the problem.
