From 6e52a9f0532f912af37bab4caf18b57d1b9845f4 Mon Sep 17 00:00:00 2001 From: Alexey Gladkov Date: Thu, 22 Apr 2021 14:27:12 +0200 Subject: Reimplement RLIMIT_MSGQUEUE on top of ucounts The rlimit counter is tied to uid in the user_namespace. This allows rlimit values to be specified in userns even if they are already globally exceeded by the user. However, the value of the previous user_namespaces cannot be exceeded.
