KEYS: Fix stale key registration at error path

2015-02-20T00:49:29+00:00

commit b26bdde5bb27f3f900e25a95e33a0c476c8c2c48 upstream.

When loading encrypted-keys module, if the last check of
aes_get_sizes() in init_encrypted() fails, the driver just returns an
error without unregistering its key type.  This results in the stale
entry in the list.  In addition to memory leaks, this leads to a kernel
crash when registering a new key type later.

This patch fixes the problem by swapping the calls of aes_get_sizes()
and register_key_type(), and releasing resources properly at the error
paths.

encrypted-keys: remove trusted-keys dependency

2011-09-14T19:23:49+00:00

Encrypted keys are decrypted/encrypted using either a trusted-key or,
for those systems without a TPM, a user-defined key.  This patch
removes the trusted-keys and TCG_TPM dependencies.
