The patch titled
selinux: inherit /proc/self/attr/keycreate across fork
has been removed from the -mm tree. Its filename is
selinux-inherit-proc-self-attr-keycreate-across-fork.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: selinux: inherit /proc/self/attr/keycreate across fork
From: Michael LeMay <mdlemay@xxxxxxxxxxxxxx>
Update SELinux to cause the keycreate process attribute held in
/proc/self/attr/keycreate to be inherited across a fork and reset upon
execve. This is consistent with the handling of the other process
attributes provided by SELinux and also makes it simpler to adapt logon
programs to properly handle the keycreate attribute.
