Subject: socket-activation: don't unlink socket we didn't create

References: bnc#757667
|
||||
|
||||
On an unpatched system, try this:
|
||||
rpcinfo <works>
|
||||
rcrpcbind restart
|
||||
rpcinfo <fails>
|
||||
|
||||
This is due to rpcbind unlinking the socket file when it exits. It
|
||||
doesn't own the socket file when socket activation is used - systemd
|
||||
does. Systemd still has an open reference to it and when rpcbind is
|
||||
restarted, it passes the open reference back to it and rpcbind is
|
||||
perfectly happy to accept it. Unfortunately, everything that needs to
|
||||
talk to rpcbind no longer can because the socket file each of those
|
||||
users needs to open is no longer on the file system.
|
||||
|
||||
This patch adds a new global that's used to avoid unlinking the
|
||||
rpcbind.sock socket file during shutdown.

systemd will, by default, pass a socket that provides both IPv4 and
|
||||
IPv6 services. RPC netconfig requires that sockets be either IPv4
|
||||
or IPv6.
|
||||
|

This patch fixes the rpcbind.socket unit file and adds a warning
|

to rpcbind should the user encounter an issue.
