I just read about Linux v3.9's SO_REUSEPORT feature and decided to implement it for Dovecot. Would be interesting to know how it works for people :) It's going to be in v2.2.6, which I'm planning on releasing tomorrow. Note especially the warning about the bug: http://hg.dovecot.org/dovecot-2.2/rev/a991a0547daa So the idea is that...

When there are multiple processes they're all listening for new connections and whichever happens to be fastest gets it. Related to this, I'm thinking about implementing SO_REUSEPORT (https://lwn.net/Articles/542629/ <https://lwn.net/Articles/542629/> <https://lwn.net/Articles/542629/ <https://lwn.net/Articles/542629/>>) soon that would change the behavior a bit.

I''m writing a gem which binds multiple sockets to the same UDP multicast port, basically like so.. socket = UDPSocket.new socket.setsockopt( Socket::SOL_SOCKET, Socket::SO_REUSEPORT, [1].pack("i_") ) socket.setsockopt(Socket::IPPROTO_IP, Socket::IP_ADD_MEMBERSHIP, addresses) socket.bind(Socket::INADDR_ANY, port) data, meta = socket.recvfrom 1024 ..which is working fine.. in OS X. But no love on my Solaris 10 x64 box. The problem? AFAICT, the availa...
