key_schedule_gc

Name:Schedule a garbage collection run.* - time precision isn't particularly important

Proto:void key_schedule_gc(time64_t gc_at)

Type:void

Parameter:

Type	Parameter	Name
time64_t	gc_at

54

now = ktime_get_real_seconds - Get the seconds portion of CLOCK_REALTIME* Returns the wall clock seconds since 1970. This replaces the* get_seconds() interface which is not y2038 safe on 32bit systems.

56

kenter("%lld", gc_at - now)

58

If gc_at <= now || st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from Then

59

kdebug("IMMEDIATE")

60

schedule_work - put work task in global workqueue*@work: job to be done* Returns %false if @work was already on the kernel-global workqueue and* %true otherwise

61

Else if gc_at < key_gc_next_run Then

62

kdebug("DEFERRED")

63

key_gc_next_run = gc_at

64

expires = jiffies + (gc_at - now) * HZ

65

mod_timer - modify a timer's timeout*@timer: the timer to be modified*@expires: new timeout in jiffies* mod_timer() is a more efficient way to update the expire field of an* active timer (if the timer is inactive it will be activated)* mod_timer(timer,

**Caller**
Name	Describe
key_garbage_collector	Reaper for unused keys.
__key_instantiate_and_link	Instantiate a key and link it into the target keyring atomically. Must be* called with the target keyring's semaphore writelocked. The target key's* semaphore need not be locked as instantiation is serialised by* key_construction_mutex.
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_set_timeout
key_revoke	key_revoke - Revoke a key
