Subject: [PATCH v4 0/3] Linux: Fix posix_spawn when user with time namespaces
Date: Tue, 10 May 2022 16:11:52 -0300	[thread overview]
Message-ID: <20220510191155.1998575-1-adhemerval.zanella@linaro.org> (raw)

The patchset adds some support to tests the fallback code to
use only use CLONE_VFORK.  It uses unshare directly because
it simpler than add container support.

Adhemerval Zanella (3):
  linux: Add CLONE_NEWTIME from Linux 5.6 to bits/sched.h
  support: Add support_enter_time_namespace
  linux: Add fallback for clone failure on posix_spawn (BZ #29115)
