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
