Name:smk_import_entry - import a label, return the list entry*@string: a text string that might be a Smack label*@len: the maximum size, or zero if it is NULL terminated

Proto:struct smack_known *smk_import_entry(const char *string, int len)

Type:struct smack_known

Parameter:

Type	Parameter	Name
const char *	string
int	len

smack = smk_parse_smack - parse smack label from a text string*@string: a text string that might contain a Smack label*@len: the maximum size, or zero if it is NULL terminated.* Returns a pointer to the clean label or an error code.

530

If IS_ERR(smack) Then Return ERR_CAST - Explicitly cast an error-valued pointer to another pointer type*@ptr: The pointer to cast.* Explicitly cast an error-valued pointer to another pointer type in such a* way as to make it clear that's what's going on.

533

mutex_lock( & smack_known_lock)

535

skp = smk_find_entry - find a label on the list, return the list entry*@string: a text string that might be a Smack label* Returns a pointer to the entry in the label list that* matches the passed string or NULL if not found.

536

If (skp != NULL) Then Go to freeout

539

skp = kzalloc - allocate memory. The memory is set to zero.*@size: how many bytes of memory are required.*@flags: the type of memory to allocate (see kmalloc).

540

If (skp == NULL) Then

541

skp = ERR_PTR( - ENOMEM)

542

Go to freeout

545

smk_known = smack

546

smk_secid = The initial value needs to be bigger than any of the* known values above.++

547

domain = smk_known

548

flags = NETLBL_SECATTR_DOMAIN | NETLBL_SECATTR_MLS_LVL

554

slen = strlen - Find the length of a string*@s: The string to be sized

555

If slen < Maximum number of bytes for the levels in a CIPSO IP option.* Why 23? CIPSO is constrained to 30, so a 32 byte buffer is* bigger than can be used, and 24 is the next lower multiple* of 8, and there are too many issues if there isn't space set Then rc = smk_netlbl_mls - convert a catset to netlabel mls categories*@catset: the Smack categories*@sap: where to put the netlabel categories* Allocates and fills attr.mls* Returns 0 on success, error code on failure.

558

Else rc = smk_netlbl_mls - convert a catset to netlabel mls categories*@catset: the Smack categories*@sap: where to put the netlabel categories* Allocates and fills attr.mls* Returns 0 on success, error code on failure.

562

If rc >= 0 Then

563

Initialization list head

564

mutex_init - initialize the mutex*@mutex: the mutex to be initialized* Initialize the mutex to unlocked state.* It is not allowed to initialize an already locked mutex.( & lock for rules )

569

smk_insert_entry - insert a smack label into a hash map,* this function must be called under smack_known_lock

570

Go to unlockout

575

576

skp = ERR_PTR(rc)

577

578

579

580

mutex_unlock - release the mutex*@lock: the mutex to be released* Unlock a mutex that has been locked by this task previously.* This function must not be used in interrupt context. Unlocking* of a not locked mutex is not allowed.

582

Return skp
