* crypto: crc32-generic - use unaligned access macros when neededEric Biggers2018-05-271-3/+4
| | | | | | | | | | | crc32-generic doesn't have a cra_alignmask set, which is desired as its ->update() works with any alignment. However, it incorrectly assumes 4-byte alignment in ->setkey() and when outputting the final digest. Fix this by using the unaligned access macros in those cases.

* crypto: x86 - Add optimized MORUS implementationsOndrej Mosnacek2018-05-191-0/+26
| | | | | | | | | | | | This patch adds optimized implementations of MORUS-640 and MORUS-1280, utilizing the SSE2 and AVX2 x86 extensions. For MORUS-1280 (which operates on 256-bit blocks) we provide both AVX2 and SSE2 implementation. Although SSE2 MORUS-1280 is slower than AVX2 MORUS-1280, it is comparable in speed to the SSE2 MORUS-640.

* crypto: tcrypt - Remove VLA usageKees Cook2018-05-051-39/+79
| | | | | | | | | | | | | In the quest to remove all stack VLA usage from the kernel[1], this allocates the return code buffers before starting jiffie timers, rather than using stack space for the array. Additionally cleans up some exit paths and make sure that the num_mb module_param() is used only once per execution to avoid possible races in the value changing.

* crypto: ccree - enable support for hardware keysGilad Ben-Yossef2018-05-051-0/+43
| | | | | | | | | | | | | | | | | | Enable CryptoCell support for hardware keys. Hardware keys are regular AES keys loaded into CryptoCell internal memory via firmware, often from secure boot ROM or hardware fuses at boot time. As such, they can be used for enc/dec purposes like any other key but cannot (read: extremely hard to) be extracted since since they are not available anywhere in RAM during runtime. The mechanism has some similarities to s390 secure keys although the keys are not wrapped or sealed, but simply loaded offline. The interface was therefore modeled based on the s390 secure keys support. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: testmgr - Allow different compression resultsMahipal Challa2018-04-211-13/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following error is triggered by the ThunderX ZIP driver if the testmanager is enabled: [ 199.069437] ThunderX-ZIP 0000:03:00.0: Found ZIP device 0 177d:a01a on Node 0 [ 199.073573] alg: comp: Compression test 1 failed for deflate-generic: output len = 37 The reason for this error is the verification of the compression results. Verifying the compression result only works if all algorithm parameters are identical, in this case to the software implementation. Different compression engines like the ThunderX ZIP coprocessor might yield different compression results by tuning the algorithm parameters. In our case the compressed result is shorter than the test vector. We should not forbid different compression results but only check that compression -> decompression yields the same result. This is done already in the acomp test. Do something similar for test_comp().

* crypto: ecc - Actually remove stack VLA usageKees Cook2018-04-213-41/+33
| | | | | | | | | | | | | | | | On the quest to remove all VLAs from the kernel[1], this avoids VLAs by just using the maximum allocation size (4 bytes) for stack arrays. All the VLAs in ecc were either 3 or 4 bytes (or a multiple), so just make it 4 bytes all the time. Initialization routines are adjusted to check that ndigits does not end up larger than the arrays. This includes a removal of the earlier attempt at this fix from commit a963834b4742 ("crypto/ecc: Remove stack VLA usage") [1] https://lkml.org/lkml/2018/3/7/621 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

In case of an error during initialization where the pointers do not yet point to allocated memory, the NULL value prevents a double free.

| | | | | | | | | | | | | | | Commit a8e5d48808e1 ("crypto: api - Keep failed instances alive") is making allocating crypto transforms sometimes fail with ELIBBAD, when multiple processes try to access encrypted files with fscrypt for the first time since boot. The problem is that the "request larval" for the algorithm is being mistaken for an algorithm which failed its tests. Fix it by only returning ELIBBAD for "non-larval" algorithms. Also don't leak a reference to the algorithm.

To recap, prior to the reverted commit, an instance that fails a self-test is kept around. However, it would satisfy any new lookups against its name and therefore the system may accumlulate an unbounded number of failed instances for the same algorithm name. The reverted commit fixed it by unregistering the instance. Hoever, this still does not prevent the creation of the same failed instance over and over again each time the name is looked up. This patch fixes it by keeping the failed instance around, just as we would if it were a normal algorithm. However, the lookup code has been udpated so that we do not attempt to create another instance as long as this failed one is still registered. Of course, you could still force a new creation by deleting the instance from user-space. A new error (ELIBBAD) has been commandeered for this purpose and will be returned when all registered algorithm of a given name have failed the self-test.
