Yama was introduced in 3.4, but Precise is 3.2 with Yama backported. The upstream fix for this bug is missing, which can cause problems when a Yama-aware program is running in 32-bit userspace (e.g. chroot) on a 64-bit kernel. Fixed upstream by 2e4930eb7c8fb20a39dfb5f8a8f80402710dcea8 SRU Justification: - impact: Yama programs running in 32-bit chroots will fail to work correctly - test case: prctl(PR_SET_PTRACER, PR_SET_PTRACER_ANY, ...) shouldn't return EINVAL on 32-bit userspace - regression potential: nearly zero. this restores a missing function, and the patch is trivial and upstream for years.
