2017-08-09crypto: ixp4xx - Fix error handling path in 'aead_perform()'Herbert Xu

A check is performed on the ipad/opad in the safexcel_hmac_sha1_setkey function, but the index used by the loop doing it is wrong. It is currently the size of the state array while it should be the size of a sha1 state. This patch fixes it.

2017-07-12crypto: caam - properly set IV after {en,de}cryptDavid Gstir
Certain cipher modes like CTS expect the IV (req->info) of ablkcipher_request (or equivalently req->iv of skcipher_request) to contain the last ciphertext block when the {en,de}crypt operation is done. This is currently not the case for the CAAM driver which in turn breaks e.g. cts(cbc(aes)) when the CAAM driver is enabled. This patch fixes the CAAM driver to properly set the IV after the {en,de}crypt operation of ablkcipher finishes.

2017-07-12crypto: caam - fix signals handlingHoria Geantă
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).

2017-07-05Cavium CNN55XX: fix broken default Kconfig entryLinus Torvalds
Every developer always thinks that _their_ code is so special and magical that it should be enabled by default. And most of them are completely and utterly wrong. That's definitely the case when you write a specialty driver for a very unsual "security processor". It does *not* get to mark itself as "default m". If you solve world hunger, and make a driver that cures people of cancer, by all means enable it by default. But afaik, the Cavium CNN55XX does neither.

2017-06-28crypto: qat - avoid an uninitialized variable warningArnd Bergmann
After commit 9e442aa6a753 ("x86: remove DMA_ERROR_CODE"), the inlining decisions in the qat driver changed slightly, introducing a new false-positive warning: drivers/crypto/qat/qat_common/qat_algs.c: In function 'qat_alg_sgl_to_bufl.isra.6': include/linux/dma-mapping.h:228:2: error: 'sz_out' may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/crypto/qat/qat_common/qat_algs.c:676:9: note: 'sz_out' was declared here The patch that introduced this is correct, so let's just avoid the warning in this driver by rearranging the unwinding after an error to make it more obvious to the compiler what is going on. The problem here is the 'if (unlikely(dma_mapping_error(dev, blp)))' check, in which the 'unlikely' causes gcc to forget what it knew about the state of the variables. Cleaning up the dma state in the reverse order it was created means we can simplify the logic so it doesn't have to know about that state, and also makes it easier to understand.

2017-06-22crypto: caam - fix gfp allocation flags (part I)Horia Geantă
Changes in the SW cts (ciphertext stealing) code in commit 0605c41cc53ca ("crypto: cts - Convert to skcipher") revealed a problem in the CAAM driver: when cts(cbc(aes)) is executed and cts runs in SW, cbc(aes) is offloaded in CAAM; cts encrypts the last block in atomic context and CAAM incorrectly decides to use GFP_KERNEL for memory allocation. Fix this by allowing GFP_KERNEL (sleeping) only when MAY_SLEEP flag is set, i.e. remove MAY_BACKLOG flag. We split the fix in two parts - first is sent to -stable, while the second is not (since there is no known failure case).
