This series is an assortment of mount-related things.
1/ resend the manpage update for "retry=" that I sent a while
back, but messed up
2/ remove a meaningless option from mountd.
3/ Fix up support for the "mountpoint" export option in mountd,
particularly making it work sensibly with NFSv4
4/ temporary hostname failure should be treated by mount.nfs
as a temporary condition
5/ Avoid advertising a temporary IPv6 address for NFSv4.0 callback.
That last point needs a kernel fix too, but I'm not sure what is best
yet.
If you have IPv6 privacy extensions enabled, then the default
address for outgoing connections is a temporary address which
becomes "deprecated" after a period of time, when another address will
become available for use. A while later the deprecated address becomes
invalid, and will stop working.
So if a connection is held open for longer than the "valid lifetime"
(valid_lft in "ip -6 addr" output) it will stop working, which isn't
what users will expect.
We could possibly close and re-open the connection after the address
becomes deprecated. Or we could insist on a 'public' address when
establishing the connection. Thoughts?
When setting the call-back address for NFSv4.0, using a public address
is the only real option, so that is what this patch does.
Thanks,
