Pull powerpc updates from Michael Ellerman: "Highlights: - Infrastructure for secure boot on some bare metal Power9 machines. The firmware support is still in development, so the code here won't actually activate secure boot on any existing systems. - A change to xmon (our crash handler / pseudo-debugger) to restrict it to read-only mode when the kernel is lockdown'ed, otherwise it's trivial to drop into xmon and modify kernel data, such as the lockdown state. - Support for KASLR on 32-bit BookE machines (Freescale / NXP). - Fixes for our flush_icache_range() and __kernel_sync_dicache() (VDSO) to work with memory ranges >4GB. - Some reworks of the pseries CMM (Cooperative Memory Management) driver to make it behave more like other balloon drivers and enable some cleanups of generic mm code. - A series of fixes to our hardware breakpoint support to properly handle unaligned watchpoint addresses. Plus a bunch of other smaller improvements, fixes and cleanups.

KEYS: trusted: Move TPM2 trusted keys code

2019-11-12T19:45:37Z

Move TPM2 trusted keys code to trusted keys subsystem. The reason being it's better to consolidate all the trusted keys code to a single location so that it can be maintained sanely. Also, utilize existing tpm_send() exported API which wraps the internal tpm_transmit_cmd() API.

KEYS: trusted: Create trusted keys subsystem

Move existing code to trusted keys subsystem. Also, rename files with "tpm" as suffix which provides the underlying implementation. Suggested-by: Jarkko Sakkinen Signed-off-by: Sumit Garg Reviewed-by: Jarkko Sakkinen Tested-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen

KEYS: Use common tpm_buf for trusted and asymmetric keys

2019-11-12T19:45:37Z

Switch to utilize common heap based tpm_buf code for TPM based trusted and asymmetric keys rather than using stack based tpm1_buf code. Also, remove tpm1_buf code.

Move tpm_buf code to common include/linux/tpm.h header so that it can be reused via other subsystems like trusted keys etc. Also rename trusted keys and asymmetric keys usage of TPM 1.x buffer implementation to tpm1_buf to avoid any compilation errors.

certs: Add wrapper function to check blacklisted binary hash

2019-11-12T01:25:50Z

The -EKEYREJECTED error returned by existing is_hash_blacklisted() is misleading when called for checking against blacklisted hash of a binary. This patch adds a wrapper function is_binary_blacklisted() to return -EPERM error if binary is blacklisted.

Pull request_key improvements from David Howells: "These are all request_key()-related, including a fix and some improvements: - Fix the lack of a Link permission check on a key found by request_key(), thereby enabling request_key() to link keys that don't grant this permission to the target keyring (which must still grant Write permission). Note that the key must be in the caller's keyrings already to be found. - Invalidate used request_key authentication keys rather than revoking them, so that they get cleaned up immediately rather than hanging around till the expiry time is passed. - Move the RCU locks outwards from the keyring search functions so that a request_key_rcu() can be provided. This can be called in RCU mode, so it can't sleep and can't upcall - but it can be called from LOOKUP_RCU pathwalk mode. - Cache the latest positive result of request_key*() temporarily in task_struct so that filesystems that make a lot of request_key() calls during pathwalk can take advantage of it to avoid having to redo the searching. This requires CONFIG_KEYS_REQUEST_CACHE=y. It is assumed that the key just found is likely to be used multiple times in each step in an RCU pathwalk, and is likely to be reused for the next step too. Note that the cleanup of the cache is done on TIF_NOTIFY_RESUME, just before userspace resumes, and on exit" * tag 'keys-request-20190626' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: keys: Kill off request_key_async{,_with_auxdata} keys: Cache result of request_key*() temporarily in task_struct keys: Provide request_key_rcu() keys: Move the RCU locks outwards from the keyring search functions keys: Invalidate used request_key authentication keys keys: Fix request_key() lack of Link perm check on found key

Move the RCU locks outwards from the keyring search functions so that it will become possible to provide an RCU-capable partial request_key() function in a later commit. Signed-off-by: David Howells
