socket.c: osmo_sock_init2: Several logic fixes and log improvements After investigating osmo-msc showing this log message and looking at the code, it's a bit difficult to find out what's going on in the code: socket.c:224 unable to bind socket: (null):0: Protocol not supported The root cause was not yet found, but probably SCTP is not enabled in the kernel of the host running it. The cod eis most probably failing during socket() and not due to bind error as the log says, so let's print an error if socket() fails. Then, if setsockopt fails, we want to still keep trying in case an extra addr was offered by addrinfo_helper. It is definetly wrong to continue if setsockopt fails, because then we are skipping the bind(), which is a fundamental part of what osmo_sock_init2 does. Then, let's print the bind error when it really happens, and re-write the extra log at the end if we reach the point at which no suitable addr is found.
