This commit adds a `selinux` variant to `procd` allowing to load an
SELinux policy at boot.
Signed-off-by: Paul Spooren <mail@aparcar.org>
Signed-off-by: Daniel Golle <daniel@makrotopia.org>
This commit adds a patch to procd to support loading the SELinux
policy early at boot time, and adjusts the procd package to use this
SELinux support when libselinux is enabled.
The procd patch has been submitted separately [1]: obviously the
intent is to have it merged in the procd Git repository rather than
have it in OpenWrt itself.

Bump procd package to reduce log spam related to missing jail binaries
in a non-jail capable system.
bcb8655 instance: add 'requirejail' attribute
An additional jail attribute 'requirejail' can now be used to indicate
mandatory use of a jailed environment and hence prevent process startup
in the event that the jail subsystem is unavailable.
Procd will now only log errors if jail is unavailable and 1) is a mandatory
requirement or 2) a procd debug level of at least 2 is in use.

Setting user and group for a jailed process caused the jail not to
come up. Fix this by passing user and group to ujail and change
user only once the jail has been setup.
This allows jailing services which refuse to run as root user.
