* keys: fix trusted/encrypted keys sparse rcu_assign_pointer messagesMimi Zohar2012-01-181-2/+2
| | | | | | | | | | | | | 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().

* KEYS: Add an RCU payload dereference macroDavid Howells2011-03-081-2/+1
| | | | | | | | | Add an RCU payload dereference macro as this seems to be a common piece of code amongst key types that use RCU referenced payloads. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
* trusted keys: Fix a memory leak in trusted_update().Jesper Juhl2011-01-241-0/+1
| | | | | | | | | | One failure path in security/keys/trusted.c::trusted_update() does not free 'new_p' while the others do. This patch makes sure we also free it in the remaining path (if datablob_parse() returns different from Opt_update).
