From add24372141855b057bf53982824c5fe50898957 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sat, 14 Oct 2017 13:46:55 +0100 Subject: selinux: remove redundant assignment to str str is being assigned to an empty string but str is never being read after that, so the assignment is redundant and can be removed. Moving the declaration of str to a more localised block, cleans up clang warning: "Value stored to 'str' is never read" Signed-off-by: Colin Ian King Signed-off-by: Paul Moore --- security/selinux/hooks.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'security') diff --git a/security/selinux/hooks.c b/security/selinux/hooks.c index 2dd4dd6..f21f1e0 100644 --- a/security/selinux/hooks.c +++ b/security/selinux/hooks.c @@ -3176,18 +3176,17 @@ static int selinux_inode_setxattr(struct dentry *dentry, const char *name, if (!has_cap_mac_admin(true)) { struct audit_buffer *ab; size_t audit_size; - const char *str; /* We strip a nul only if it is at the end, otherwise the * context contains a nul and we should audit that */ if (value) { - str = value; + const char *str = value; + if (str[size - 1] == '\0') audit_size = size - 1; else audit_size = size; } else { - str = ""; audit_size = 0; } ab = audit_log_start(current->audit_context, GFP_ATOMIC, AUDIT_SELINUX_ERR); -- cgit v1.1
