From 5bf37ec3e0f5eb79f23e024a7fbc8f3557c087f0 Mon Sep 17 00:00:00 2001 From: "Serge E. Hallyn" Date: Wed, 8 Apr 2009 16:55:58 -0500 Subject: cap_prctl: don't set error to 0 at 'no_change' One-liner: capsh --print is broken without this patch. In certain cases, cap_prctl returns error > 0 for success. However, the 'no_change' label was always setting error to 0. As a result, for example, 'prctl(CAP_BSET_READ, N)' would always return 0. It should return 1 if a process has N in its bounding set (as by default it does). I'm keeping the no_change label even though it's now functionally the same as 'error'.
