Wrong:

$ cd /src/kernels/ubuntu/precise ; git grep PTRACE_EVENT_SECCOMP
...
include/linux/ptrace.h:#define PTRACE_EVENT_SECCOMP     8

Correct:

$ cd /src/kernels/ubuntu/trusty ; git grep PTRACE_EVENT_SECCOMP
...
include/uapi/linux/ptrace.h:#define PTRACE_EVENT_SECCOMP        7

Title:
  precise has wrong PTRACE_EVENT_SECCOMP value

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

Bug description:
  In v3.2, there was confusion over the new "PTRACE_EVENT_EXIT" value.
  Ultimately, upstream fixed it, but in the precise backporting of
  seccomp, the wrong value was used:
  5cdf389aee90109e2e3d88085dea4dd5508a3be7

  As a result, seccomp filteres expecting ptrace managers don't work
  correctly on precise.

  The attached patch backports the upstream PTRACE_EVENT_EXIT value and
  restores the correct PTRACE_EVENT_SECCOMP value.
