[d-kernel] [PATCH 0/2] Kiosk: turn off secureexec for allowed executables

[mcpain@altlinux.org]

From: Oleg Solovyov <mcpain@altlinux.org>

Modern desktop environments tends to become incompatible with kiosk.
KDE works so far but systemd unit fails to launch [1]
GNOME breaks fatally [2]

This happens because /lib/systemd/systemd uses secure_getenv() to get
environment variables and receives NULL since secureexec is enforced by
Kiosk LSM.

Since I am uncertain what else is to be replaced with getenv() in
systemd and how much things it will break in future I chose to allow
running those executables without setting up secureexec.

By default, secureexec is set unless explicitly told not to do so.

  kiosk: split kiosk_nl_send_*
  kiosk: add secureexec parameter
