SYSCALL_DEFINE5	Extract the description of a new key from userspace and either add it as a* new key to the specified keyring or update a matching key in that keyring.* If the description is NULL or an empty string, the key type is asked to* generate one from the payload.
SYSCALL_DEFINE4	Search the process keyrings and keyring trees linked from those for a* matching key. Keyrings must have appropriate Search permission to be* searched.* If a key is found, it will be attached to the destination keyring if there's
keyctl_get_keyring_ID	Get the ID of the specified process keyring.* The requested keyring must have search permission to be found.* If successful, the ID of the requested keyring will be returned.
keyctl_update_key	Update a key's data payload from the given data.* The key must grant the caller Write permission and the key type must support* updating for this to work. A negative key can be positively instantiated* with this call.* If successful, 0 will be returned

keyctl_keyring_link	Create a link from a keyring to a key if there's no matching key in the* keyring, otherwise replace the link to the matching key with a link to the* new key.* The key must grant the caller Link permission and the the keyring must grant
keyctl_keyring_unlink	Unlink a key from a keyring.* The keyring must grant the caller Write permission for this to work; the key* itself need not grant the caller anything. If the last link to a key is* removed then that key will be scheduled for destruction.
keyctl_keyring_move	Move a link to a key from one keyring to another, displacing any matching* key from the destination keyring.* The key must grant the caller Link permission and both keyrings must grant* the caller Write permission
keyctl_describe_key	Return a description of a key to userspace
keyctl_keyring_search	Search the specified keyring and any keyrings it links to for a matching* key

keyctl_session_to_parent	Attempt to install the calling process's session keyring on the process's* parent process.* The keyring must exist and must grant the caller LINK permission, and the* parent process must be single-threaded and must have the same effective
keyctl_restrict_keyring	Apply a restriction to a given keyring.* The caller must have Setattr permission to change keyring restrictions.* The requested type name may be a NULL pointer to reject all attempts* to link to the keyring. In this case, _restriction must also be NULL.
lookup_user_key	Look up a key ID given us by userspace with a given permissions mask to get* the key it refers to.* Flags can be passed to request that special keyrings be created if referred* to directly, to permit partially constructed keys to be found and to skip
request_key_and_link	quest_key_and_link - Request a key and cache it in a keyring.@type: The type of key we want.@description: The searchable description of the key.*@domain_tag: The domain in which the key operates.
proc_keys_show
key_get_persistent	Get the persistent keyring for a specific UID and link it to the nominated* keyring.
