There are three functions for dealing with these: - key_ref_t make_key_ref(const struct key *key, - unsigned long possession); + key_ref_t make_key_ref(const struct key *key, bool possession); struct key *key_ref_to_ptr(const key_ref_t key_ref); - unsigned long is_key_possessed(const key_ref_t key_ref); + bool is_key_possessed(const key_ref_t key_ref); The first function constructs a key reference from a key pointer and - possession information (which must be 0 or 1 and not any other value). + possession information (which must be true or false). The second function retrieves the key pointer from a reference and the third retrieves the possession flag. diff --git a/include/linux/key.h b/include/linux/key.h index 4dfde1161c5e..51bce2950de4 100644 --- a/include/linux/key.h +++ b/include/linux/key.h @@ -99,7 +99,7 @@ struct keyring_name; typedef struct __key_reference_with_attributes *key_ref_t; static inline key_ref_t make_key_ref(const struct key *key, - unsigned long possession) + bool possession) { return (key_ref_t) ((unsigned long) key | possession); } @@ -109,7 +109,7 @@ static inline struct key *key_ref_to_ptr(const key_ref_t key_ref) return (struct key *) ((unsigned long) key_ref & ~1UL); } -static inline unsigned long is_key_possessed(const key_ref_t key_ref) +static inline bool is_key_possessed(const key_ref_t key_ref) { return (unsigned long) key_ref & 1UL; } diff --git a/security/keys/keyring.c b/security/keys/keyring.c index 6ece7f2e5707..f78406372ebe 100644 --- a/security/keys/keyring.c +++ b/security/keys/keyring.c @@ -329,9 +329,10 @@ key_ref_t keyring_search_aux(key_ref_t keyring_ref, struct keyring_list *keylist; struct timespec now; - unsigned long possessed, kflags; + unsigned long kflags; struct key *keyring, *key; key_ref_t key_ref; + bool possessed; long err; int sp, nkeys, kix; @@ -542,8 +543,8 @@ key_ref_t __keyring_search_one(key_ref_t keyring_ref, key_perm_t perm) { struct keyring_list *klist; - unsigned long possessed; struct key *keyring, *key; + bool possessed; int nkeys, loop; keyring = key_ref_to_ptr(keyring_ref); |
