commit d80771c08363ad7fbf0f56f5301e7ca65065c582 upstream.
When compiling with CONFIG_DEBUG_ATOMIC_SLEEP=y the mxs-dcp driver
prints warnings such as:
WARNING: CPU: 0 PID: 120 at kernel/sched/core.c:7736 __might_sleep+0x98/0x9c
do not call blocking ops when !TASK_RUNNING; state=1 set at [<8081978c>] dcp_chan_thread_sha+0x3c/0x2ec
The problem is that blocking ops will manipulate current->state
themselves so it is not allowed to call them between
set_current_state(TASK_INTERRUPTIBLE) and schedule().
Fix this by converting the per-chan mutex to a spinlock (it only
protects tiny list ops anyway) and rearranging the wait logic so that
callbacks are called current->state as TASK_RUNNING. Those callbacks
will indeed call blocking ops themselves so this is required.

[ Upstream commit 0e7d4d932ffc23f75efb31a8c2ac2396c1b81c55 ]
This patch fixes two typos related to unregistering algorithms supported by
SAHARAH 3. In sahara_register_algs the wrong algorithms are unregistered
in case of an error. In sahara_unregister_algs the wrong array is used to
determine the iteration count.

commit 0522236d4f9c5ab2e79889cb020d1acbe5da416e upstream.
This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX
implementations. The problem is that the blkcipher_* functions should
not be called in atomic context.
The bugs can be reproduced via the AF_ALG interface by trying to
encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the
VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then
trigger BUG in crypto_yield():

commit 46d8c4b28652d35dc6cfb5adf7f54e102fc04384 upstream.
This was detected by the self-test thanks to Ard's chunking patch.
I finally got around to testing this out on my ancient Via box. It
turns out that the workaround got the assembly wrong and we end up
doing count + initial cycles of the loop instead of just count.
This obviously causes corruption, either by overwriting the source
that is yet to be processed, or writing over the end of the buffer.
On CPUs that don't require the workaround only ECB is affected.
On Nano CPUs both ECB and CBC are affected.
This patch fixes it by doing the subtraction prior to the assembly.

commit 1411b5218adbcf1d45ddb260db5553c52e8d917c upstream.
In the vmx AES init routines we do a printk(KERN_INFO ...) to report
the fallback implementation we're using.
However with a slow console this can significantly affect the speed of
crypto operations. Using 'cryptsetup benchmark' the removal of the
printk() leads to a ~5x speedup for aes-cbc decryption.
So remove them.

commit 362f924b64ba0f4be2ee0cb697690c33d40be721 upstream.
Those are stupid and code should use static_cpu_has_safe() or
boot_cpu_has() instead. Kill the least used and unused ones.
The remaining ones need more careful inspection before a conversion can
happen. On the TODO.

commit 225ece3e7dad4cfc44cca38ce7a3a80f255ea8f1 upstream.
In case DECO0 cannot be acquired - i.e. run_descriptor_deco0() fails
with -ENODEV, caam_probe() enters an endless loop:
run_descriptor_deco0
ret -ENODEV
-> instantiate_rng
-ENODEV, overwritten by -EAGAIN
ret -EAGAIN
-> caam_probe
-EAGAIN results in endless loop
It turns out the error path in instantiate_rng() is incorrect,
the checks are done in the wrong order.

commit 203f45003a3d03eea8fa28d74cfc74c354416fdb upstream.
queue_cache_init is first called for the Control Word Queue
(n2_crypto_probe). At that time, queue_cache[0] is NULL and a new
kmem_cache will be allocated. If the subsequent n2_register_algs call
fails, the kmem_cache will be released in queue_cache_destroy, but
queue_cache_init[0] is not set back to NULL.
So when the Module Arithmetic Unit gets probed next (n2_mau_probe),
queue_cache_init will not allocate a kmem_cache again, but leave it
as its bogus value, causing a BUG() to trigger when queue_cache[0] is
eventually passed to kmem_cache_zalloc:
n2_crypto: Found N2CP at /virtual-devices@100/n2cp@7

[ Upstream commit 778f81d6cdb7d25360f082ac0384d5103f04eca5 ]
If crypto4xx is used in conjunction with dm-crypt, the available
ring buffer elements are not enough to handle the load properly.
On an aes-cbc-essiv:sha256 encrypted swap partition the read
performance is abyssal: (tested with hdparm -t)
/dev/mapper/swap_crypt:
Timing buffered disk reads: 14 MB in 3.68 seconds = 3.81 MB/sec
The patch increases both PPC4XX_NUM_SD and PPC4XX_NUM_PD to 256.
This improves the performance considerably:
/dev/mapper/swap_crypt:
Timing buffered disk reads: 104 MB in 3.03 seconds = 34.31 MB/sec
Furthermore, PPC4XX_LAST_SD, PPC4XX_LAST_GD and PPC4XX_LAST_PD
can be easily calculated from their respective PPC4XX_NUM_*
constant.

[ Upstream commit 07de4bc88ce6a4d898cad9aa4c99c1df7e87702d ]
In a regular interrupt handler driver was finishing the crypt/decrypt
request by calling complete on crypto request. This is disallowed since
converting to skcipher in commit b286d8b1a690 ("crypto: skcipher - Add
skcipher walk interface") and causes a warning:
WARNING: CPU: 0 PID: 0 at crypto/skcipher.c:430 skcipher_walk_first+0x13c/0x14c
The interrupt is marked shared but in fact there are no other users
sharing it. Thus the simplest solution seems to be to just use a
threaded interrupt handler, after converting it to oneshot.

commit 7459e1d25ffefa2b1be799477fcc1f6c62f6cec7 upstream.
Driver does not properly handle the case when signals interrupt
wait_for_completion_interruptible():
-it does not check for return value
-completion structure is allocated on stack; in case a signal interrupts
the sleep, it will go out of scope, causing the worker thread
(caam_jr_dequeue) to fail when it accesses it
wait_for_completion_interruptible() is replaced with uninterruptable
wait_for_completion().
We choose to block all signals while waiting for I/O (device executing
the split key generation job descriptor) since the alternative - in
order to have a deterministic device state - would be to flush the job
ring (aborting *all* in-progress jobs).

RNG instantiation was previously fixed by
commit 62743a4145bb9 ("crypto: caam - fix RNG init descriptor ret. code checking")

with a JUMP HALT command, checking for errors should be similar too,
i.e. status code 7000_0000h should be considered successful.

commit d128af17876d79b87edf048303f98b35f6a53dbc upstream.
The AEAD givenc descriptor relies on moving the IV through the
output FIFO and then back to the CTX2 for authentication. The
SEQ FIFO STORE could be scheduled before the data can be
read from OFIFO, especially since the SEQ FIFO LOAD needs
to wait for the SEQ FIFO LOAD SKIP to finish first. The
SKIP takes more time when the input is SG than when it's
a contiguous buffer. If the SEQ FIFO LOAD is not scheduled
before the STORE, the DECO will hang waiting for data
to be available in the OFIFO so it can be transferred to C2.
In order to overcome this, first force transfer of IV to C2
by starting the "cryptlen" transfer first and then starting to
store data from OFIFO to the output buffer.

commit 1d2d87e81ea21f64c19b95ef228b865a6880e17e upstream.
There are a few things missed by the conversion to the
new AEAD interface:
1 - echainiv(authenc) encrypt shared descriptor
The shared descriptor is incorrect: due to the order of operations,
at some point in time MATH3 register is being overwritten.
2 - buffer used for echainiv(authenc) encrypt shared descriptor
Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
exclusive and thus use the same buffer in context state: sh_desc_enc.
However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
leading to errors when echainiv(authenc(...)) algorithms are used:
DECO: desc idx 14: Header Error. Invalid length or parity, or
certain other problems.
While here, also fix a typo: dma_mapping_error() is checking
for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

commit 12d3f49e1ffbbf8cbbb60acae5a21103c5c841ac upstream.
All of the VMX AES ciphers (AES, AES-CBC and AES-CTR) are set at
priority 1000. Unfortunately this means we never use AES-CBC and
AES-CTR, because the base AES-CBC cipher that is implemented on
top of AES inherits its priority.
To fix this, AES-CBC and AES-CTR have to be a higher priority. Set
them to 2000.
Testing on a POWER8 with:
cryptsetup benchmark --cipher aes --key-size 256
Shows decryption speed increase from 402.4 MB/s to 3069.2 MB/s,
over 7x faster. Thanks to Mike Strosaker for helping me debug
