[PATCH] selinux: inherit /proc/self/attr/keycreate across fork
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.
