Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6: (24 commits) integrity: special fs magic As pointed out by Jonathan Corbet, the timer must be deleted before ERROR: code indent should use tabs where possible The tpm_dev_release function is only called for platform devices, not pnp Protect tpm_chip_list when transversing it. Renames num_open to is_open, as only one process can open the file at a time. Remove the BKL calls from the TPM driver, which were added in the overall netlabel: Add configuration support for local labeling cipso: Add support for native local labeling and fixup mapping names netlabel: Changes to the NetLabel security attributes to allow LSMs to pass full contexts selinux: Cache NetLabel secattrs in the socket's security struct selinux: Set socket NetLabel based on connection endpoint netlabel: Add functionality to set the security attributes of a packet netlabel: Add network address selectors to the NetLabel/LSM domain mapping netlabel: Add a generic way to create ordered linked lists of network addrs netlabel: Replace protocol/NetLabel linking with refrerence counts smack: Fix missing calls to netlbl_skbuff_err() selinux: Fix missing calls to netlbl_skbuff_err() selinux: Fix a problem in security_netlbl_sid_to_secattr() selinux: Better local/forward check in selinux_ip_postroute() ...
