[PATCH v1 0/2] proc: Relax check of mount visibility

Alexey Gladkov <gladkov.alexey@xxxxxxxxx> · Mon, 27 Jul 2020 16:14:09 +0200

If only the dynamic part of procfs is mounted (subset=pid), then there is no
need to check if procfs is fully visible to the user in the new user namespace.

  proc: Relax check of mount visibility
  Show /proc/self/net only for CAP_NET_ADMIN
