| * crypto: qat - avoid an uninitialized variable warningArnd Bergmann2017-06-281-19/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Cavium CNN55XX: fix broken default Kconfig entryLinus Torvalds2017-07-051-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Make these functions (skb_put, __skb_put and pskb_put) return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the 2nd part of fixing the usage of GFP_KERNEL for memory allocations, taking care off all the places that haven't caused a real problem / failure. Again, the issue being fixed is that GFP_KERNEL should be used only when MAY_SLEEP flag is set, i.e. MAY_BACKLOG flag usage is orthogonal.

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).

The datasheet isn't very clear about when the digest is ready to retrieve and is seems the bit SS_DATA_END is cleared when the digest was computed *but* that doesn't mean the digest is ready to retrieve in the registers. A ndelay(1) is added before reading the computed digest to ensure it is available in the SS_MD[] registers.
