I like the idea, slightly different patch is in.

Yeah, I guess when the problem is so ugly the solution must be ugly too :-(
Have you tested r3740?
Btw, you forgot kfreebsd-{9,10}
Yes, I think this should be handled in glibc, and the sockaddr_un be
fixed to match what the kernel expects, the compat code would be there
to fix applications built against the bogus sockaddr_un type.
In fact, we already clip the passed size in our eglibc in
bind() and connect(), it might suffi

More importantly, there is the question you raised of whether this
should be done in userspace by libc instead. That would avoid
upstream having to wonder, "why should we care what happens when
someone using a BSD4.3-style bind() calls our BSD4.4-style kernel"?
So it's tempting.

It's the actual size of the sun_path field of struct sock

Is this 108 the actual length? ISTR it was just a placeh

Thanks for the pointer.
Here's "struct sockaddr_un" in eglibc (socket/sys/un.h, after a little
typedef-chasing):
unsigned char sun_len;
unsigned char sun_family;

Hi,
Typical kfreebsd-amd64 experimental system. When I try to use "cupt
update" after booting with kfreebsd 9, it always fails:
