Subject: [PATCH 00/23] KEYS: Fixes


Hi James,

Here are a bunch of fixes for Linux keyrings, including:

 (*) Fixing up the refcount handling now that key structs use the
     refcount_t type and the refcount_t ops don't allow a 0->1 transition.

 (*) Fix a potential NULL deref after error in x509_cert_parse().

 (*) Don't put data for the crypto algorithms to use on the stack.

 (*) Fix the handling of a null payload being passed to add_key().

 (*) Fix incorrect cleanup an uninitialised key_preparsed_payload in
     key_update().

 (*) Explicit sanitisation of potentially secure data before freeing.

 (*) Fixes for the Diffie-Helman code.

Note that I rebased the patches on top of -rc4 to avoid problems with a tty
locking bug encountered whilst trying to test it.

The patches can be found here also:
