[Bug 817187] Re: change in readlink() errno in 2.6.39 and later kernels causes FTBFS for packages with older gnulib

[Jamie Strandboge]

** Description changed:

  This is due to the following:
  http://lists.gnu.org/archive/html/bug-gnulib/2011-03/msg00308.html
  
  "coreutils' "make check" failed on rawhide due to a kernel change
  in how readlink and readlinkat treat the empty file name.
  Before, they'd fail with ENOENT.  Now, it's EINVAL."
  
  This was discovered when preparing security updates for libvirt, but
  will affect more than libvirt, (see Debian http://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=630902). For libvirt, the patch in the above bug
  can be applied to gnulib/tests/test-areadlink.h to get these building
  again on newer releases. This is SRU-worthy, as libvirt will not build
  once the buildds are running newer kernels. If it is not SRUd before the
  next security update, the security team will do it as part of their
  update process.
