From 1b50eed9cac0e8e5e4d3a522d8aa267f7f8f8acb Mon Sep 17 00:00:00 2001 From: Steve Grubb Date: Mon, 3 Apr 2006 14:06:13 -0400 Subject: [PATCH] audit inode patch Previously, we were gathering the context instead of the sid. Now in this patch, we gather just the sid and convert to context only if an audit event is being output. This patch brings the performance hit from 146% down to 23% Signed-off-by: Al Viro --- security/selinux/exports.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'security/selinux') diff --git a/security/selinux/exports.c b/security/selinux/exports.c index 333c4c7..07ddce7 100644 --- a/security/selinux/exports.c +++ b/security/selinux/exports.c @@ -14,6 +14,7 @@ #include #include #include +#include #include "security.h" #include "objsec.h" @@ -26,3 +27,26 @@ void selinux_task_ctxid(struct task_struct *tsk, u32 *ctxid) else *ctxid = 0; } + +int selinux_ctxid_to_string(u32 ctxid, char **ctx, u32 *ctxlen) +{ + if (selinux_enabled) + return security_sid_to_context(ctxid, ctx, ctxlen); + else { + *ctx = NULL; + *ctxlen = 0; + } + + return 0; +} + +void selinux_get_inode_sid(const struct inode *inode, u32 *sid) +{ + if (selinux_enabled) { + struct inode_security_struct *isec = inode->i_security; + *sid = isec->sid; + return; + } + *sid = 0; +} + -- cgit v1.1
