Subject: [PATCH v6 0/7] capabilities: Introduce CAP_CHECKPOINT_RESTORE
Date: Sun, 19 Jul 2020 12:04:10 +0200
Message-ID: <20200719100418.2112740-1-areber@redhat.com> (raw)

This is v6 of the 'Introduce CAP_CHECKPOINT_RESTORE' patchset. The
changes to v5 are:

 * split patch dealing with /proc/self/exe into two patches:
   * first patch to enable changing it with CAP_CHECKPOINT_RESTORE
     and detailed history in the commit message
   * second patch changes -EINVAL to -EPERM
 * use kselftest_harness.h infrastructure for test
 * replace if (!capable(CAP_SYS_ADMIN) || !capable(CAP_CHECKPOINT_RESTORE))
   with if (!checkpoint_restore_ns_capable(&init_user_ns))

Adrian Reber (5):
  capabilities: Introduce CAP_CHECKPOINT_RESTORE
  pid: use checkpoint_restore_ns_capable() for set_tid
  pid_namespace: use checkpoint_restore_ns_capable() for ns_last_pid
  proc: allow access in init userns for map_files with
    CAP_CHECKPOINT_RESTORE
  selftests: add clone3() CAP_CHECKPOINT_RESTORE test

Nicolas Viennot (2):
  prctl: Allow local CAP_CHECKPOINT_RESTORE to change /proc/self/exe
  prctl: exe link permission error changed from -EINVAL to -EPERM
