rcpbind.sock removed when daemon is killed
Last modified: 2015-12-13 04:51:57 EST
Hello, When rpcbind is socket activated by systemd, it's not creating the rpcbind.sock socket itself but it is still trying to unlink() it in the terminate() function. On Fedora, the socket is created as root by systemd but then the daemon is running as rpc user, this means that when the terminate function is called it has not the permission to remove the socket; on fedora strace shows me: unlink("/var/run/rpcbind.lock") = -1 EACCES (Permission denied) But on other distribution, like debian, where rpcbind daemon is running as root (we could discuss whether it's a good idea or not), the rpcbind daemon has the permission to remove the socket and then the daemon is never respawned. The user needs to manually restart the rcpbind.socket unit. I guess that the daemon should try to remember if it has created the socket, and if it's not the case it should leave it alone.

Created attachment 1091963 [details] 0001-Delete-the-unix-socket-only-if-we-have-created-it.patch
I can confirm that the attached patch fixed my issue where rpcbind daemon was taking the responsibility of removing the socket even if it didn't create it. If rpcbind is not socket activated, it removes the socket on exit like it was doing before

I'll take it from there... TIA!
