I am finally back to looking at an old PR#205193.
The problem is that the nfsuserd daemon expects upcalls from the
kernel
that are from localhost (127.0.0.1) and when jails are running on the
system,
127.0.0.1 is mapped to some other IP#. (I think it might be the
address of the
first net interface on the machine, but I'm not sure?)
And what does it do on system that have no 127.1 or no IPv4 at all
anymore or don’t even support IPv4 anymore?
Is there a way that nfsuserd.c can find out what this IP# is?
Yes, could do easily but wouldn’t work for my above case, would it? I
can help you with the code for v4 and jails if you help me with the code
for IPv6?
(I have a patch that converts nfsuserd.c to using an AF_LOCAL socket,
but that
breaks for some setups. I think it was when the directory the socket
was being
created in is NFSv4 mounted, but I can't remember exactly how it
fails.)
Thanks for any help with this, rick
