Basile <blueness@gentoo.org> +Updated patch for the new Kconfig system in grsec 2.9.1 + +--- +From: Kerin Millar <kerframil@gmail.com> + +grsecurity contains a number of options which allow certain protections +to be applied to or exempted from members of a given group. However, the +default GIDs specified in the upstream patch are entirely arbitrary and +there is no telling which (if any) groups the GIDs will correlate with +on an end-user's system. Because some users don't pay a great deal of +attention to the finer points of kernel configuration, it is probably +wise to specify some reasonable defaults so as to stop careless users +from shooting themselves in the foot. + +diff -Naur a/grsecurity/Kconfig b/grsecurity/Kconfig +--- a/grsecurity/Kconfig 2012-10-13 09:51:35.000000000 -0400 ++++ b/grsecurity/Kconfig 2012-10-13 09:52:32.000000000 -0400 +@@ -700,7 +700,7 @@ + config GRKERNSEC_AUDIT_GID + int "GID for auditing" + depends on GRKERNSEC_AUDIT_GROUP +- default 1007 ++ default 100 + + config GRKERNSEC_EXECLOG + bool "Exec logging" +@@ -949,7 +949,7 @@ + config GRKERNSEC_TPE_UNTRUSTED_GID + int "GID for TPE-untrusted users" + depends on GRKERNSEC_TPE && !GRKERNSEC_TPE_INVERT +- default 1005 ++ default 100 + help + Setting this GID determines what group TPE restrictions will be + *enabled* for.
