Currently ovsdb-server creates its own Unix domain socket at
/run/openvswitch/db.sock, and dependent services need explicit
ordering and assertion checks to ensure the socket is available.
This series transfers socket ownership to systemd, which creates
the listening socket before any service starts. The socket remains
available across service restarts, so clients queue instead of
getting connection failures.
Changes since v1:
- stream: Use str_to_long() instead of strtol(); return EINVAL
instead of ERANGE on invalid fd number (Aaron Conole).
- ovs-ctl: Also unset LISTEN_PIDFDID when clearing socket
activation environment variables (Aaron Conole).
Timothy Redaelli (5):
stream: Add "pfd:" passive stream for pre-opened file descriptors.
ovs-ctl: Detect systemd socket activation.
rhel: Add ovsdb-server.socket unit for systemd socket activation.
debian: Add ovsdb-server.socket unit for systemd socket activation.
tests: Add pfd stream tests.
