Maybe. I don't know that part of the code well. Looking at INN, we ran
into the problem with listen() rather than bind(), so maybe this is a
different issue.
/* Walk the list of file descriptors, listen on each, and create new
channels for each. Some IPv6 systems already listening on the IPv6
wildcard address will return EADDRINUSE when trying to listen to the
IPv4 socket; just ignore that error. */
okay = false;
for (i = 0; i < count; i++) {
if (fds[i] < 0)
continue;
if (listen(fds[i], MAXLISTEN) < 0) {
if (i != 0 && errno == EADDRINUSE)
continue;
syswarn("SERVER cant listen to socket");
}
rc = CHANcreate(fds[i], CTremconn, CSwaiting, RCreader, RCwritedone);
notice("%s rcsetup %s", LogName, CHANname(rc));
RCHANadd(rc);
RCchan[start + i] = rc;
okay = true;
}
However, I seem to recall seeing errors with bind as well that we're
currently just ignoring, so I probably don't have a complete fix in INN
either.
