[Bug 790971] Re: binfmt-support doesn't honor flags: in /usr/share/binfmts/foo

[Colin Watson]

Actually, 'C' implies 'O' in the kernel, so there's no need to change
update-binfmts here - just delete 'flags: OC' from the files in qemu-
user-static and add 'credentials yes'.

Title:
  binfmt-support doesn't honor flags: in /usr/share/binfmts/foo

Bug description:
  Binary package hint: binfmt-support

  qemu-user-static ships a number of binfmt handlers under
  /usr/share/binfmts which are registered in the postinst using 'update-
  binfmts --import qemu-$target'.  In natty, the resulting registrations
  under /var/lib/binfmts (and in /proc/sys/fs/binfmt_misc) don't respect
  the value of the flags: field set in the source file.  As a result,
  foreign-arch suid binaries can't be run under qemu because the kernel
  has been told to use the suid bit from the non-setuid qemu
  interpreter, instead of the one from the target binary.

  Please fix update-binfmts to respect the flags: field, which I think
  worked in previous versions.
