meta-app-framework: applaunchd: run under a separate user
Since applaunchd needs to start/stop systemd units, the user is granted elevated systemd unit-management permissions via PolKit policy. If applaunchd and all the apps run under the same agl-driver user, all the apps have these elevated systemd permissions too. Separating them into different users allows removing elevated systemd unit-management permission from individual apps, but leaving such permission for applaunchd, which enhances overall security of the system. - add new applaunchd user and group - switch applaunchd (gRPC) service to be started under new user - since HTML5 apps haven't migrated to gRPC yet and still use D-Bus API, applaunchd-dbus gets activated by agl-session and runs under agl-driver - temporarily add agl-driver user into the applaunchd group and switch PolKit policy to check for applaunchd group, instead of the user - once D-Bus API is completely deprecated, agl-driver user can be removed from applaunchd group Bug-AGL: SPEC-4579 Signed-off-by: Denys Dmytriyenko <denys@konsulko.com> Change-Id: I75384177578bba6cb458a81df6a9dc1738c972e0 Reviewed-on: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/28039 Tested-by: Jenkins Job builder account ci-image-build: Jenkins Job builder account ci-image-boot-test: Jenkins Job builder account Reviewed-by: Jan-Simon Moeller <jsmoeller@linuxfoundation.org>
