[Bug 1183616] Re: seccomp-bpf missing on ARM in precise


This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
precise' to 'verification-done-precise'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  seccomp-bpf missing on ARM in precise

Status in “linux” package in Ubuntu:
Status in “linux” source package in Precise:

Bug description:
  While seccomp-bpf was backported into precise, it was only for x86.
  Now that the ARM support is upstream too, it would be great to have
  the same level of support on ARM in the LTS kernel.

  I'll prepare patches.

  ARM devices lack seccomp-bpf protections when running seccomp-aware applications (e.g. Chrome)

  [Test Case]
  git clone https://github.com/redpig/seccomp.git
  cd seccomp/tests
  All tests should pass

  [Regression Potential]
  Low: ARM currently has no seccomp-bpf support, so this is very unlikely to cause regressions. The changes that are common between x86 and ARM bring Precise closer to upstream seccomp-bpf, so this is similarly unlike to cause regressions (as this code is more correct than what is currently in Precise). Changes have been minimized, and tested.
