From 00447872a643787411c2c0cb1df6169dda8b0c47 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Sat, 12 Apr 2008 19:06:42 -0700 Subject: NetLabel: Allow passing the LSM domain as a shared pointer Smack doesn't have the need to create a private copy of the LSM "domain" when setting NetLabel security attributes like SELinux, however, the current NetLabel code requires a private copy of the LSM "domain". This patches fixes that by letting the LSM determine how it wants to pass the domain value. * NETLBL_SECATTR_DOMAIN_CPY The current behavior, NetLabel assumes that the domain value is a copy and frees it when done * NETLBL_SECATTR_DOMAIN New, Smack-friendly behavior, NetLabel assumes that the domain value is a reference to a string managed by the LSM and does not free it when done Signed-off-by: Paul Moore Acked-by: James Morris Signed-off-by: David S.
