Name:Preallocate memory so that a key can be linked into to a keyring.
Proto:int __key_link_begin(struct key *keyring, const struct keyring_index_key *index_key, struct assoc_array_edit **_edit)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct key * | keyring | |
const struct keyring_index_key * | index_key | |
struct assoc_array_edit ** | _edit |
1301 | kenter("%d,%s,%s,", key serial number , name, description) |
1307 | * _edit = NULL |
1309 | ret = -EKEYREVOKED |
1310 | If st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from Then Go to error |
1316 | edit = assoc_array_insert - Script insertion of an object into an associative array*@array: The array to insert into |
1328 | If Not dead_leaf Then |
1329 | ret = key_payload_reserve - Adjust data quota reservation for the key's payload*@key: The key to make the reservation for |
1331 | If ret < 0 Then Go to error_cancel |
1336 | kleave(" = 0") |
1337 | Return 0 |

key_reject_and_link | key_reject_and_link - Negatively instantiate a key and link it into the keyring.*@key: The key to instantiate.*@timeout: The timeout on the negative key.*@error: The error to return when the key is hit. |
key_create_or_update | key_create_or_update - Update or create and instantiate a key.*@keyring_ref: A pointer to the destination keyring with possession flag.*@type: The type of key.*@description: The searchable description for the key. |
key_link | key_link - Link a key to a keyring*@keyring: The keyring to make the link in |
key_move | key_move - Move a key from one keyring to another*@key: The key to move*@from_keyring: The keyring to remove the link from |
construct_alloc_key | Allocate a new key in under-construction state and attempt to link it in to* the requested keyring.* May return a key that's already under construction instead if there was a* race between two thread calling request_key(). |
