+What: Audit Login UID
+Date: 2005-02-01
+KernelVersion: 2.6.11-rc2 1e2d1492e178 ("[PATCH] audit: handle loginuid through proc")
+Contact: linux-audit@xxxxxxxxxx
+Format: %u
+Users: audit and login applications
+Description:
+ The /proc/$pid/loginuid pseudofile is written to set and
+ read to get the audit login UID of process $pid. If it is
+ unset, permissions are not needed to set it. The accessor must
+ have CAP_AUDIT_CONTROL in the initial user namespace to write
+ it if it has been set. It cannot be written again if
+ AUDIT_FEATURE_LOGINUID_IMMUTABLE is enabled. It cannot be
+ unset if AUDIT_FEATURE_ONLY_UNSET_LOGINUID is enabled.
