Hopefully this mail gets through to someone who can apply this patch
to NfsUtils git.
I have been trying on and off for a year or so to get Nfs4 mounts to
work over Ipv6. Finally with the latest git it seemed to work.
That is, it worked when you wildcard all internet addresses.
/home/nfs4
*(rw,fsid=0,sync,root_squash,no_all_squash,no_subtree_check)
Unfortunately subnetting wasn't working, so I dug into the code to
figure out why. It turned out that it was something simple (once I
managed to get my head into the code). I've attached a patch
against the current git that fixes it. With the patch applied, ipv6
subnetting such as the following works.
/home/nfs4 2001:470:b:3e::/
64(rw,fsid=0,sync,root_squash,no_all_squash,no_subtree_check)
/home/nfs4 2001:470:b:3e::/ffff:ffff:ffff:ffff::
(rw,fsid=0,sync,root_squash,no_all_squash,no_subtree_check)
IPv6 support in mountd is entirely experimental (ie not guaranteed to
work), and exists only my personal git repo, not in the official nfs-
utils git repo. However, it looks like you are working against my code.
Also, we prefer patches submitted inline, not as attachments, as that
makes it easy to hit "reply" and comment on the content of the patch.
A patch description and a Signed-off-by: line is required. Take a
look in the archives of this mailing list for examples.
Basically your patch misapplies the address mask in check_subnet_v6,
so I don't think it's the right fix. Instead of "sin6 & mask" you
have "sin6 & sin6" which basically means the mask is ignored, and the
check will always succeed.
Maybe the mask generation code in init_netmask() is not correct?
