Please pull these key susbystem fixes for 4.3, per the message from David
Howells:
"Here are two patches, the first of which at least should go upstream
immediately:
(1) Prevent a user-triggerable crash in the keyrings destructor when a
negatively instantiated keyring is garbage collected. I have also
seen this triggered for user type keys.
(2) Prevent the user from using requesting that a keyring be created and
instantiated through an upcall. Doing so is probably safe since the
keyring type ignores the arguments to its instantiation function -
but we probably shouldn't let keyrings be created in this manner."
