>From bd076c7245d02be0cc01b7c09bd7170ec5946492 Mon Sep 17 00:00:00 2001 From: Serge E. Hallyn <[EMAIL PROTECTED]> Date: Sun, 17 Feb 2008 20:28:07 -0500 Subject: [PATCH 1/1] file capabilities: simplify signal check
Simplify the uid equivalence check in cap_task_kill(). Anyone can kill a process owned by the same uid. Without this patch wireshark is reported to fail. Signed-off-by: Serge E.
