From 270e8573145a26de924e2dc644596332d400445b Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Fri, 19 May 2017 10:09:32 -0700 Subject: [PATCH] selinux: Remove redundant check for unknown labeling behavior The check is already performed in ocontext_read() when the policy is loaded. Removing the array also fixes the following warning when building with clang: security/selinux/hooks.c:338:20: error: variable 'labeling_behaviors' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration] Signed-off-by: Matthias Kaehlcke Acked-by: Stephen Smalley Signed-off-by: Paul Moore --- security/selinux/hooks.c | 16 ---------------- 1 file changed, 16 deletions(-) diff --git a/security/selinux/hooks.c b/security/selinux/hooks.c index 627f291fb6c1..cfb7ce339adc 100644 --- a/security/selinux/hooks.c +++ b/security/selinux/hooks.c @@ -398,18 +398,6 @@ static void superblock_free_security(struct super_block *sb) kfree(sbsec); } -/* The file system's label must be initialized prior to use. */ - -static const char *labeling_behaviors[7] = { - "uses xattr", - "uses transition SIDs", - "uses task SIDs", - "uses genfs_contexts", - "not configured for labeling", - "uses mountpoint labeling", - "uses native labeling", -}; - static inline int inode_doinit(struct inode *inode) { return inode_doinit_with_dentry(inode, NULL); @@ -524,10 +512,6 @@ static int sb_finish_set_opts(struct super_block *sb) } } - if (sbsec->behavior > ARRAY_SIZE(labeling_behaviors)) - printk(KERN_ERR "SELinux: initialized (dev %s, type %s), unknown behavior\n", - sb->s_id, sb->s_type->name); - sbsec->flags |= SE_SBINITIALIZED; if (selinux_is_sblabel_mnt(sb)) sbsec->flags |= SBLABEL_MNT;
