From e1db1f8218998c428e8b087dda6660449ef2891a Mon Sep 17 00:00:00 2001 From: Kenny Levinsen Date: Tue, 11 Jan 2022 11:08:44 +0100 Subject: Print deprecation notice when running SUID SUID privilege drop is needed for the "builtin"-backend of libseat, which copied our old "direct" backend behavior for the sake of compatibility and ease of transition. libseat now has a better alternative in the form of seatd-launch. It uses the normal seatd daemon and libseat backend and takes care of SUID for us. Add a soft deprecation warning to highlight our future intent of removing this code. The deprecation cycle is needed to avoid surprises when sway no longer drops privileges. --- sway/main.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/sway/main.c b/sway/main.c index 6c71048b..b6f8a8bf 100644 --- a/sway/main.c +++ b/sway/main.c @@ -153,6 +153,9 @@ static void log_kernel(void) { static bool drop_permissions(void) { if (getuid() != geteuid() || getgid() != getegid()) { + sway_log(SWAY_ERROR, "!!!
