Subject: /usr/sbin/exportfs: exportfs cannot handle IPv6 addresses

Date: Fri, 9 Dec 2016 12:39:49 +0100

Package: nfs-kernel-server
Version: 1:1.2.8-9.2
Severity: important
File: /usr/sbin/exportfs
Tags: ipv6

Dear Maintainer,

 when trying to export/unexport a path i cannot give IPv6 addresses to
 exportfs.

# showmount -e 
Export list for testhost:
/path/sub fe80::%eth0/10

# exportfs -u [fe80::%eth0]/10:/path/sub
exportfs: Invalid exporting option: [fe80

When removing the [] i get the same error (without [)
When using something like 2001:0db8:1234::/64 the same error occurs.

Subject: nfs-utils updated to 1.3.4-1, please check your bug #847557

Date: Thu, 15 Dec 2016 14:15:18 +0100 (CET)

Thanks for providing a bug report for nfs-utils.
https://bugs.debian.org/847557

There are over 100 open bugs[1] in the nfs-utils package.

The package in Debian sid has recently been updated to v1.3.4-1.

The upstream changelog[2] indicates that many bugs have been fixed
since the version that you tried.

Can you please help reduce the number of bug reports so
developers can see which issues are really outstanding:

- if any other bug in the list[1] is a duplicate of yours, you
  can send a "merge[3]" command to the bug server to link the bugs.

- if your bug is closed by an upstream fix or the latest package,
  please send a "fixed[4]" command to the bug server specifying
  which version introduced the fix.  This will close the bug for
  newer versions.

- if you have time to test the new package, your help would be very
  welcome.  Please see the discussion about the package in
  bug 847681[5].  The source code can be obtained from collab-maint
  and compiled on a Debian jessie/stable system without any
  modifications.  I currently run it on such a system with a 4.7 kernel
  from jessie-backports[6] due to crashes[7] on NFS servers running the
  stable kernel.

Thanks again for your bug report.

Regards,

Daniel

Trying the package from sid (1:1.3.4-1):

# exportfs [2001:0db8:1234::]/64:/path/sub 
# showmount -e localhost
Export list for localhost:
/path/sub 2001:0db8:1234::/64
# exportfs -u [2001:0db8:1234::]/64:/path/sub


The bug is fixed in nfs-kernel-server version 1:1.3.4-1

Thanks
