As noted in #1939, both
socket:bind()andsocket:connect()succeed even ifmksock_bind_addr()fails. The result is that the socket gets silently assigned a random ephemeral source port, instead of the requested one, which in turn has the ultimate effect of RPC scripts randomly failing.This PR will inspect the actual assigned source port and trigger a retry as needed.
It will be merged in after November 1 unless concerns are raised.
