crypto: arm64/gcm - disentangle ghash and gcm setkey() routines

The remaining ghash implementation does not support aggregation, and so
there is no point in including the precomputed powers of H in the key
struct. So move that into the GCM setkey routine, and get rid of the
shared sub-routine entirely.

crypto: arm64/ghash - drop PMULL based shash

There are two ways to implement SIMD accelerated GCM on arm64:
- using the PMULL instructions for carryless 64x64->128 multiplication,
  in which case the architecture guarantees that the AES instructions are
  available as well, and so we can use the AEAD implementation that combines
  both,
- using the PMULL instructions for carryless 8x8->16 bit multiplication,
  which is implemented as a shash, and can be combined with any ctr(aes)
  implementation by the generic GCM AEAD template driver.

So let's drop the 64x64->128 shash driver, which is never needed for GCM,
and not suitable for use anywhere else.

automatically use the (de)compressor near the CPU calling acomp_alloc().
However, it is not necessarily correct because users who send acomp_req

First, I removed the trailing comma in the PRECOMPUTE line.

Second, I substituted:
1. GHASH_4_ENCRYPT_4_PARALLEL_DEC -> GHASH_4_ENCRYPT_4_PARALLEL_dec
2. GHASH_4_ENCRYPT_4_PARALLEL_ENC -> GHASH_4_ENCRYPT_4_PARALLEL_enc

With these changes I was able to build with LLVM_IAS=1 and boot on bare metal.

I confirmed that this works with Linux-kernel v5.7.5 final.

NOTE: This patch is on top of Linux v5.7 final.

John Allen [Mon, 22 Jun 2020 20:24:02 +0000 (15:24 -0500)]
crypto: ccp - Fix use of merged scatterlists

Running the crypto manager self tests with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS may result in several types of errors
when using the ccp-crypto driver:

alg: skcipher: cbc-des3-ccp encryption failed on test vector 0; expected_error=0, actual_error=-5 ...

alg: skcipher: ctr-aes-ccp decryption overran dst buffer on test vector 0 ...

alg: ahash: sha224-ccp test failed (wrong result) on test vector ...

These errors are the result of improper processing of scatterlists mapped
for DMA.

Given a scatterlist in which entries are merged as part of mapping the
scatterlist for DMA, the DMA length of a merged entry will reflect the
combined length of the entries that were merged. The subsequent
scatterlist entry will contain DMA information for the scatterlist entry
after the last merged entry, but the non-DMA information will be that of
the first merged entry.

The ccp driver does not take this scatterlist merging into account. To
address this, add a second scatterlist pointer to track the current
position in the DMA mapped representation of the scatterlist. Both the DMA
representation and the original representation of the scatterlist must be
tracked as while most of the driver can use just the DMA representation,
scatterlist_map_and_copy() must use the original representation and
expects the scatterlist pointer to be accurate to the original
representation.

In order to properly walk the original scatterlist, the scatterlist must
be walked until the combined lengths of the entries seen is equal to the
DMA length of the current entry being processed in the DMA mapped
representation.

crc-t10dif: Fix potential crypto notify dead-lock

The crypto notify call occurs with a read mutex held so you must
not do any substantial work directly.  In particular, you cannot
call crypto_alloc_* as they may trigger further notifications
which may dead-lock in the presence of another writer.

This patch fixes this by postponing the work into a work queue and
taking the same lock in the module init function.

While we're at it this patch also ensures that all RCU accesses are
marked appropriately (tested with sparse).

Finally this also reveals a race condition in module param show
function as it may be called prior to the module init function.
It's fixed by testing whether crct10dif_tfm is NULL (this is true
iff the init function has not completed assuming fallback is false).

Eric Biggers [Thu, 4 Jun 2020 18:52:53 +0000 (11:52 -0700)]
crypto: algboss - don't wait during notifier callback

When a crypto template needs to be instantiated, CRYPTO_MSG_ALG_REQUEST
is sent to crypto_chain.  cryptomgr_schedule_probe() handles this by
starting a thread to instantiate the template, then waiting for this
thread to complete via crypto_larval::completion.

This can deadlock because instantiating the template may require loading
modules, and this (apparently depending on userspace) may need to wait
for the crc-t10dif module (lib/crc-t10dif.c) to be loaded.  But
crc-t10dif's module_init function uses crypto_register_notifier() and
therefore takes crypto_chain.rwsem for write.  That can't proceed until
the notifier callback has finished, as it holds this semaphore for read.

Fix this by removing the wait on crypto_larval::completion from within
cryptomgr_schedule_probe().  It's actually unnecessary because
crypto_alg_mod_lookup() calls crypto_larval_wait() itself after sending
CRYPTO_MSG_ALG_REQUEST.

This only actually became a problem in v4.20 due to commit b76377543b73
("crc-t10dif: Pick better transform if one becomes available"), but the
unnecessary wait was much older.

4 years agoRevert "btrfs: switch to iomap_dio_rw() for dio"
David Sterba [Tue, 9 Jun 2020 17:56:06 +0000 (19:56 +0200)]
Revert "btrfs: switch to iomap_dio_rw() for dio"

This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.

The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.

Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.

There have been discussions how to fix that, but revert seems to be the
least intrusive option.

This happens, because ALE VLAN entries on these SoCs do not contain port
