thread keyring - Per-thread keyring
DESCRIPTION
The
thread keyringis a keyring used to anchor keys on behalf of a process. It is only createdwhen a thread requests it.A special serial number value,
KEY_SPEC_THREAD_KEYRING, is defined thatcan be used in lieu of the calling thread's thread keyring's actual serialnumber.From the keyctl utility, '
@t' can be used instead of a numeric key ID inmuch the same way, but as keyctl is a program run after forking, this is of noutility.Thread keyrings are not inherited across clone() and are cleared by execve().A thread keyring is destroyed when the thread that refers to it exits.If a thread doesn't have a thread keyring when it is accessed, then the threadkeyring will be created if the keyring is to be modified, otherwise errorENOKEY will be issued.
