-Subject: [PATCH] In capng_apply, allow continuing in spite of errors
-
-In capng_apply, if we blow up trying to adjust the bounding set without
-proper permissions, continue into the capabilities in case they called
-with SELECT_BOTH and they don't bother checking the return code. This
-will at least leave the application in a potentially safer state.
