The Atmel SHA driver was treating -EBUSY as indication of queueing to backlog without checking that backlog is enabled for the request. Fix it by checking request flags. Cc: <stable@vger.kernel.org> Signed-off-by:

crypto: af_alg - Avoid sock_graft call warning The newly added sock_graft warning triggers in af_alg_accept. It's harmless as we're essentially doing sock->sk = sock->sk. The sock_graft call is actually redundant because all the work it does is subsumed by sock_init_data. However, it was added to placate SELinux as it uses it to initialise its internal state. This patch avoisd the warning by making the SELinux call directly. Reported-by:

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).

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. Signed-off-by:

Changes in the SW cts (ciphertext stealing) code in commit 0605c41c ("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).

When enable_single_wr is not enabled, the DSE will only write those parts of a result descriptor that need updating, which means a final result descriptor will be written in 2 or 3 smaller transfers. When enable_single_wr is enabled the DSE will combine these 2-3 updates into one large write transfer, generally improving performance. Signed-off-by:
