+Subject: [PATCH] pkit: Pass system-bus-name as subject, not pid
|
|
+
|
|
+Previously, we were forcing polkit to scrape /proc/pid itself for the
|
|
+uid, which is subject to a race condition if the caller execve()s a
|
|
+setuid binary. Passing system-bus-name as a subject allows polkit to
|
|
+use the valid information from the system bus.
