Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  NFSv3 exports not fully functional with older NFS clients

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 12.04.4 LTS
  Reproducible bug in nfs exports starting from 3.2.0-58
  Starting kernel version 3.2.0-58, it is impossible to checkout any subversion project on a NFSv3 mounted share on a Solaris 10 machine.
  svn co svn+ssh://svn.url/project
  returns the following
  svn: Can't read directory 'trunk': Value too large for defined data type
  Mounting the share with NFSv2 doesn't create this problem
  Possibly related to the following (excerpts from changelog):
    * ext4: return 32/64-bit dir name hash according to usage type
      - LP: #1257010
    * nfsd: vfs_llseek() with 32 or 64 bit offsets (hashes)
      - LP: #1257010

  
  Steps to reproduce:
  - On Ubuntu 12.04.4 installed both kernel versions 3.2.0-57 and 3.2.0-58
  - Boot with 3.2.0-57
  - Start nfs-kernel-server and export share
  - mount on Solaris 10 as NFSv3 (default)
  - login as share-authorized user on NFS share
  - create dir and checkout svn
  - ok
  - Reboot nfs server with kernel 3.2.0-58
  - unmount and mount share on Solaris machine
  - Try to svn co again, returns error "svn: Can't read directory 'trunk': Value too large for defined data type"

  It looks like 32bit NFS clients cannot handle 64 bit cookies relate to
  readdir and readdirplus, so this problem might not be exclusive to
  Solaris (this is the machine on which we could reproduce it)

  Thanks
  Alessandro
