I've found an acceptable workaround. I will send a patch to
dev at openvswitch.org soon. In short, to connect or bind a socket with a
name that is too long, open a fd for the dirname of the socket then use
/proc/self/fd/<dirfd>/basename as the name. This seems to work fine.
It won't handle the case where the socket's basename is too long, but
that's also not the problem here.
Thanks for the analysis!
