From 6c5b3fc0147f79d714d2fe748b5869d7892ef2e7 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Fri, 10 Oct 2008 10:16:33 -0400 Subject: selinux: Cache NetLabel secattrs in the socket's security struct Previous work enabled the use of address based NetLabel selectors, which while highly useful, brought the potential for additional per-packet overhead when used. This patch attempts to mitigate some of that overhead by caching the NetLabel security attribute struct within the SELinux socket security structure. This should help eliminate the need to recreate the NetLabel secattr structure for each packet resulting in less overhead.
