From 5fb49870e6d48d81d8ca0e1ef979073dc9a820f7 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Thu, 22 Apr 2010 14:46:19 -0400 Subject: selinux: Use current_security() when possible There were a number of places using the following code pattern: struct cred *cred = current_cred(); struct task_security_struct *tsec = cred->security; ... which were simplified to the following: struct task_security_struct *tsec = current_security(); Signed-off-by: Paul Moore Acked-by: Eric Paris Signed-off-by: James Morris --- security/selinux/hooks.c | 17 ++++++----------- 1 file changed, 6 insertions(+), 11 deletions(-) (limited to 'security') diff --git a/security/selinux/hooks.c b/security/selinux/hooks.c index e95004010c8b..0f524b7d102e 100644 --- a/security/selinux/hooks.c +++ b/security/selinux/hooks.c @@ -188,7 +188,7 @@ static inline u32 task_sid(const struct task_struct *task) */ static inline u32 current_sid(void) { - const struct task_security_struct *tsec = current_cred()->security; + const struct task_security_struct *tsec = current_security(); return tsec->sid; } @@ -1558,8 +1558,7 @@ static int may_create(struct inode *dir, struct dentry *dentry, u16 tclass) { - const struct cred *cred = current_cred(); - const struct task_security_struct *tsec = cred->security; + const struct task_security_struct *tsec = current_security(); struct inode_security_struct *dsec; struct superblock_security_struct *sbsec; u32 sid, newsid; @@ -2157,8 +2156,7 @@ static int selinux_bprm_set_creds(struct linux_binprm *bprm) static int selinux_bprm_secureexec(struct linux_binprm *bprm) { - const struct cred *cred = current_cred(); - const struct task_security_struct *tsec = cred->security; + const struct task_security_struct *tsec = current_security(); u32 sid, osid; int atsecure = 0; @@ -2533,8 +2531,7 @@ static int selinux_inode_init_security(struct inode *inode, struct inode *dir, char **name, void **value, size_t *len) { - const struct cred *cred = current_cred(); - const struct task_security_struct *tsec = cred->security; + const struct task_security_struct *tsec = current_security(); struct inode_security_struct *dsec; struct superblock_security_struct *sbsec; u32 sid, newsid, clen; @@ -3669,8 +3666,7 @@ static int sock_has_perm(struct task_struct *task, struct sock *sk, u32 perms) static int selinux_socket_create(int family, int type, int protocol, int kern) { - const struct cred *cred = current_cred(); - const struct task_security_struct *tsec = cred->security; + const struct task_security_struct *tsec = current_security(); u32 newsid; u16 secclass; @@ -3685,8 +3681,7 @@ static int selinux_socket_create(int family, int type, static int selinux_socket_post_create(struct socket *sock, int family, int type, int protocol, int kern) { - const struct cred *cred = current_cred(); - const struct task_security_struct *tsec = cred->security; + const struct task_security_struct *tsec = current_security(); struct inode_security_struct *isec = SOCK_INODE(sock)->i_security; struct sk_security_struct *sksec; int err = 0; -- cgit v1.2.3-59-g8ed1b
