2018-08-23treewide: convert ISO_8859-1 text comments to utf-8Arnd Bergmann1-6/+6
Almost all files in the kernel are either plain text or UTF-8 encoded. A couple however are ISO_8859-1, usually just a few characters in a C comments, for historic reasons. This converts them all to UTF-8 for consistency.

2018-08-08crypto/nx: Initialize 842 high and normal RxFIFO control registersHaren Myneni1-3/+28
NX increments readOffset by FIFO size in receive FIFO control register when CRB is read. But the index in RxFIFO has to match with the corresponding entry in FIFO maintained by VAS in kernel. Otherwise NX may be processing incorrect CRBs and can cause CRB timeout. VAS FIFO offset is 0 when the receive window is opened during initialization. When the module is reloaded or in kexec boot, readOffset in FIFO control register may not match with VAS entry. This patch adds nx_coproc_init OPAL call to reset readOffset and queued entries in FIFO control register for both high and normal FIFOs.

2018-08-03crypto: ccp - Check for NULL PSP pointer at module unloadTom Lendacky1-0/+3
Should the PSP initialization fail, the PSP data structure will be freed and the value contained in the sp_device struct set to NULL. At module unload, psp_dev_destroy() does not check if the pointer value is NULL and will end up dereferencing a NULL pointer. Add a pointer check of the psp_data field in the sp_device struct in psp_dev_destroy() and return immediately if it is NULL.

The ccree driver had a sanity check that we are not asked to encrypt an XTS buffer bigger than a sane sector size since XTS IV needs to include the sector number in the IV so this is not expected in any real use case. Unfortunately, this breaks cryptsetup benchmark test which has a synthetic performance test using 64k buffer of data with the same IV. Remove the sanity check and allow the user to hang themselves and/or run benchmarks if they so wish.

2018-08-03crypto: hisilicon - SEC security accelerator driverJonathan Cameron8-0/+2895
This accelerator is found inside hisilicon hip06 and hip07 SoCs. Each instance provides a number of queues which feed a different number of backend acceleration units. The queues are operating in an out of order mode in the interests of throughput. The silicon does not do tracking of dependencies between multiple 'messages' or update of the IVs as appropriate for training. Hence where relevant we need to do this in software.

2018-07-20crypto: padlock-aes - Fix Nano workaround data corruptionHerbert Xu1-2/+6
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. Fixes: a76c1c23d0c3 ("crypto: padlock-aes - work around Nano CPU...")

2018-07-13crypto: ccp - Fix command completion detection raceTom Lendacky1-2/+2
The wait_event() function is used to detect command completion. The interrupt handler will set the wait condition variable when the interrupt is triggered. However, the variable used for wait_event() is initialized after the command has been submitted, which can create a race condition with the interrupt handler and result in the wait_event() never returning. Move the initialization of the wait condition variable to just before command submission.

2018-07-12tcp: use monotonic timestamps for PAWSArnd Bergmann1-1/+1
Using get_seconds() for timestamps is deprecated since it can lead to overflows on 32-bit systems. While the interface generally doesn't overflow until year 2106, the specific implementation of the TCP PAWS algorithm breaks in 2038 when the intermediate signed 32-bit timestamps overflow. A related problem is that the local timestamps in CLOCK_REALTIME form lead to unexpected behavior when settimeofday is called to set the system clock backwards or forwards by more than 24 days. While the first problem could be solved by using an overflow-safe method of comparing the timestamps, a nicer solution is to use a monotonic clocksource with ktime_get_seconds() that simply doesn't overflow (at least not until 136 years after boot) and that doesn't change during settimeofday(). To make 32-bit and 64-bit architectures behave the same way here, and also save a few bytes in the tcp_options_received structure, I'm changing the type to a 32-bit integer, which is now safe on all architectures. Finally, the ts_recent_stamp field also (confusingly) gets used to store a jiffies value in tcp_synq_overflow()/tcp_synq_no_recent_overflow(). This is currently safe, but changing the type to 32-bit requires some small changes there to keep it working.

2018-07-09crypto: ccree - use CBC-CS3 CTS modeGilad Ben-Yossef1-15/+5
The ccree driver implemented NIST 800-38A CBC-CS2 ciphertext format, which only reverses the last two blocks if the stolen ciphertext amount are none zero. Move it to the kernel chosen format of CBC-CS3 which swaps the final blocks unconditionally and rename it to "cts" now that it complies with the kernel format and passes the self tests. Ironically, the CryptoCell REE HW does just that, so the fix is dropping the code that forced it to use plain CBC if the ciphertext was block aligned.

2018-07-09crypto: remove redundant type flags from tfm allocationEric Biggers4-9/+4
Some crypto API users allocating a tfm with crypto_alloc_$FOO() are also specifying the type flags for $FOO, e.g. crypto_alloc_shash() with CRYPTO_ALG_TYPE_SHASH. But, that's redundant since the crypto API will override any specified type flag/mask with the correct ones. So, remove the unneeded flags. This patch shouldn't change any actual behavior.
