From a61ecd329cfa951b7d36c13e9e2a07e7761c0e89 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 23 Mar 2018 23:34:22 +0000 Subject: apparmor: fix error returns checks by making size a ssize_t Currently variable size is a unsigned size_t, hence comparisons to see if it is less than zero (for error checking) will always be false. Fix this by making size a ssize_t Detected by CoverityScan, CID#1466080 ("Unsigned compared against 0") Fixes: 8e51f9087f40 ("apparmor: Add support for attaching profiles via xattr, presence and value") Signed-off-by: Colin Ian King Signed-off-by: John Johansen --- security/apparmor/domain.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'security') diff --git a/security/apparmor/domain.c b/security/apparmor/domain.c index 57cc892e05a2..590b7e8cd21c 100644 --- a/security/apparmor/domain.c +++ b/security/apparmor/domain.c @@ -314,7 +314,7 @@ static int aa_xattrs_match(const struct linux_binprm *bprm, struct aa_profile *profile, unsigned int state) { int i; - size_t size; + ssize_t size; struct dentry *d; char *value = NULL; int value_size = 0, ret = profile->xattr_count; -- cgit v1.2.3-59-g8ed1b
