Pull audit updates from Paul Moore:
 "We've got a reasonably broad set of audit patches for the v5.2 merge
  window, the highlights are below:

   - The biggest change, and the source of all the arch/* changes, is
     the patchset from Dmitry to help enable some of the work he is
     doing around PTRACE_GET_SYSCALL_INFO.

     To be honest, including this in the audit tree is a bit of a
     stretch, but it does help move audit a little further along towards
     proper syscall auditing for all arches, and everyone else seemed to
     agree that audit was a "good" spot for this to land (or maybe they
     just didn't want to merge it? dunno.).

   - We can now audit time/NTP adjustments.

   - We continue the work to connect associated audit records into a
     single event"

The flags field in 'struct shash_desc' never actually does anything.
The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP.
However, no shash algorithm ever sleeps, making this flag a no-op.

With this being the case, inevitably some users who can't sleep wrongly
pass MAY_SLEEP.  These would all need to be fixed if any shash algorithm
actually started sleeping.  For example, the shash_ahash_*() functions,
which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP
from the ahash API to the shash API.  However, the shash functions are
called under kmap_atomic(), so actually they're assumed to never sleep.

Even if it turns out that some users do need preemption points while
hashing large buffers, we could easily provide a helper function
crypto_shash_update_large() which divides the data into smaller chunks
and calls crypto_shash_update() and cond_resched() for each chunk.  It's
not necessary to have a flag in 'struct shash_desc', nor is it necessary
to make individual shash algorithms aware of this at all.

Therefore, remove shash_desc::flags, and document that the
crypto_shash_*() functions can be called from any context.

Allow to use EC-RDSA signatures for IMA by determining signature type by
the hash algorithm name. This works good for EC-RDSA since Streebog and
EC-RDSA should always be used together.

In commit fa516b66a1bf ("EVM: Allow runtime modification of the set of
verified xattrs"), the call to audit_log_start() is missing a context to
link it to an audit event. Since this event is in user context, add
the process' syscall context to the record.

In addition, the orphaned keyword "locked" appears in the record.
Normalize this by changing it to logging the locking string "." as any
other user input in the "xattr=" field.

Pull tpm updates from James Morris:

 - Clean up the transmission flow

   Cleaned up the whole transmission flow. Locking of the chip is now
   done in the level of tpm_try_get_ops() and tpm_put_ops() instead
   taking the chip lock inside tpm_transmit(). The nested calls inside
   tpm_transmit(), used with the resource manager, have been refactored
   out.

   Should make easier to perform more complex transactions with the TPM
   without making the subsystem a bigger mess (e.g. encrypted channel
   patches by James Bottomley).

 - PPI 1.3 support

   TPM PPI 1.3 introduces an additional optional command parameter that
   may be needed for some commands. Display the parameter if the command
   requires such a parameter. Only command 23 (SetPCRBanks) needs one.

   The PPI request file will show output like this then:

      # echo "23 16" > request
      # cat request
      23 16

      # echo "5" > request
      # cat request
      5

 - Extend all PCR banks in IMA

   Instead of static PCR banks array, the array of available PCR banks
   is now allocated dynamically. The digests sizes are determined
   dynamically using a probe PCR read without relying crypto's static
   list of hash algorithms.

   This should finally make sealing of measurements in IMA safe and
   secure.

 - TPM 2.0 selftests

   Added a test suite to tools/testing/selftests/tpm2 previously outside
   of the kernel tree: https://github.com/jsakkine-intel/tpm2-scripts

    request similarly makes keys on the platform keyring accessible for

Pull audit updates from Paul Moore:
 "A lucky 13 audit patches for v5.1.

  Despite the rather large diffstat, most of the changes are from two
  bug fix patches that move code from one Kconfig option to another.

  Beyond that bit of churn, the remaining changes are largely cleanups
  and bug-fixes as we slowly march towards container auditing. It isn't
  all boring though, we do have a couple of new things: file
  capabilities v3 support, and expanded support for filtering on
  filesystems to solve problems with remote filesystems.

  All changes pass the audit-testsuite.  Please merge for v5.1"
