KEYS: Merge the type-specific data with the payload data

2015-10-21T14:18:36+00:00

Merge the type-specific data with the payload data into one four-word chunk as it seems pointless to keep them separate. Use user_key_payload() for accessing the payloads of overloaded user-defined keys.

encrypted-keys: fix rcu and sparse messages

2012-01-17T23:41:30+00:00

Enabling CONFIG_PROVE_RCU and CONFIG_SPARSE_RCU_POINTER resulted in "suspicious rcu_dereference_check() usage!" and "incompatible types in comparison expression (different address spaces)" messages. Access the masterkey directly when holding the rwsem. Changelog v1: - Use either rcu_read_lock()/rcu_derefence_key()/rcu_read_unlock() or remove the unnecessary rcu_derefence() - David Howells Reported-by: Dmitry Kasatkin Signed-off-by: Mimi Zohar Signed-off-by: David Howells Signed-off-by: James Morris

keys: fix trusted/encrypted keys sparse rcu_assign_pointer messages

2012-01-17T23:41:29+00:00

Define rcu_assign_keypointer(), which uses the key payload.rcudata instead of payload.data, to resolve the CONFIG_SPARSE_RCU_POINTER message: "incompatible types in comparison expression (different address spaces)" Replace the rcu_assign_pointer() calls in encrypted/trusted keys with rcu_assign_keypointer().

encrypted-keys: IS_ERR need include/err.h

Fixes this build error: security/keys/encrypted-keys/masterkey_trusted.c: In function 'request_trusted_key': security/keys/encrypted-keys/masterkey_trusted.c:35:2: error: implicit declaration of function 'IS_ERR' Signed-off-by: Stephen Rothwell Signed-off-by: Mimi Zohar

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. Signed-off-by: Mimi Zohar
