From 55efac6cbcea0d8edda9c6820620ceb390009e7a Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 14 Feb 2012 21:33:51 +0100 Subject: login: track login class (i.e. one of "user", "greeter", "lock-screen") for each session This introduces the new PAM environment variable XDG_SESSION_CLASS. If not set, defaults to "user". This is useful for apps that want to distuingish real user logins from "fake" ones which just exist to show a gdm login screen or a lock screen. --- src/login/pam-module.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) (limited to 'src/login/pam-module.c') diff --git a/src/login/pam-module.c b/src/login/pam-module.c index 46509245fb..8544413a08 100644 --- a/src/login/pam-module.c +++ b/src/login/pam-module.c @@ -321,7 +321,7 @@ _public_ PAM_EXTERN int pam_sm_open_session( struct passwd *pw; bool kill_processes = false, debug = false; - const char *username, *id, *object_path, *runtime_path, *service = NULL, *tty = NULL, *display = NULL, *remote_user = NULL, *remote_host = NULL, *seat = NULL, *type, *cvtnr = NULL; + const char *username, *id, *object_path, *runtime_path, *service = NULL, *tty = NULL, *display = NULL, *remote_user = NULL, *remote_host = NULL, *seat = NULL, *type, *class, *cvtnr = NULL; char **controllers = NULL, **reset_controllers = NULL, **kill_only_users = NULL, **kill_exclude_users = NULL; DBusError error; uint32_t uid, pid; @@ -465,13 +465,20 @@ _public_ PAM_EXTERN int pam_sm_open_session( type = !isempty(display) ?
