| * | crypto: caam - handle zero-length AEAD outputHoria Geantă2019-02-013-24/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent AEAD changes in testmgr framework introduced by commit a0d608ee5ebf ("crypto: testmgr - unify the AEAD encryption and decryption test vectors") uncovered an error in the CAAM drivers, since they don't correctly handle the case when AEAD output length is zero. Add checks to avoid feeding zero-length req->dst to DMA API. Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | crypto: caam - add support for cmac(aes)Iuliana Prodan2019-02-013-33/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add cmac(aes) keyed hash offloading support. Similar to xcbc implementation, driver must make sure there are still some bytes buffered when ahash_final() is called. This way HW is able to decide whether padding is needed and which key to derive (L -> K1 / K2) for the last block.

| * | crypto: clarify name of WEAK_KEY request flagEric Biggers2019-01-2516-27/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it sounds like it is requesting a weak key. Actually, it is requesting that weak keys be forbidden (for algorithms that have the notion of "weak keys"; currently only DES and XTS do). Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which it can be easily confused. (This in fact happened in the UX500 driver, though just in some debugging messages.) Therefore, make the intent clear by renaming it to CRYPTO_TFM_REQ_FORBID_WEAK_KEYS. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For decryption in CBC mode we need to save the last ciphertext block for use as the next IV. However, we were trying to do this also with zero sized ciphertext resulting in a panic. Fix this by only doing the copy if the ciphertext length is at least of IV size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were copying the last ciphertext block into the IV field for CBC before removing the DMA mapping of the output buffer with the result of the buffer sometime being out-of-sync cache wise and were getting intermittent cases of bad output IV. Fix it by moving the DMA buffer unmapping before the copy.

* Remove 'type' argument from access_ok() functionLinus Torvalds2019-01-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * treewide: surround Kconfig file paths with double quotesMasahiro Yamada2018-12-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.
