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)
