Title:
  readdir(3) fails for cifs mount in 32-bit process on amd64

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  After upgrading a server from januty/amd64 to karmic/amd64 our custom
  written backup program started failing.  A further upgrade to
  lucid/amd64 didn't help.  And testing it on a desktop with
  maverick/amd64 (the one I just ran "ubuntu-bug" on) shows it doesn't
  work on that either.  I've reduced the problem down to being
  readdir(3) failing in 32-bit processes on cifs mounts.

  Hopefully the code in the attached list.c file demonstrates the
  problem.  I compiled it with "gcc -m32 -o list32 list.c && gcc -m64 -o
  list64 list.c" then ran list32 and list64, each with an argument of a
  path to a directory on a cifs mount.  The list32 executable failed
  with "Cannot allocate memory", but list64 works fine.  The remote
  share I'm trying to access is on a machine running Windows Server
  2003.

  Cheers,
  Mark.
