scsi: fix upper bounds check of sense key in scsi_sense_key_string()

commit a87eeb900dbb9f8202f96604d56e47e67c936b9d upstream. Commit 655ee63cf371 ("scsi constants: command, sense key + additional sense string") added a "Completed" sense string with key 0xF to snstext[], but failed to updated the upper bounds check of the sense key in scsi_sense_key_string().

crypto: caam - fix IV loading for authenc (giv)decryption

2016-09-15T06:20:29+00:00

commit 8b18e2359aff2ab810aba84cebffc9da07fef78f upstream. For algorithms that implement IV generators before the crypto ops, the IV needed for decryption is initially located in req->src scatterlist, not in req->iv. Avoid copying the IV into req->iv by modifying the (givdecrypt) descriptors to load it directly from req->src. aead_givdecrypt() is no longer needed and goes away.

vhost/scsi: fix reuse of &vq->iov[out] in response

2016-09-15T06:20:29+00:00

commit a77ec83a57890240c546df00ca5df1cdeedb1cc3 upstream. The address of the iovec &vq->iov[out] is not guaranteed to contain the scsi command's response iovec throughout the lifetime of the command. Rather, it is more likely to contain an iovec from an immediately following command after looping back around to vhost_get_vq_desc(). Pass along the iovec entirely instead.

irqchip/mips-gic: Implement activate op for device domain

2016-09-15T06:20:29+00:00

commit 2564970a381651865364974ea414384b569cb9c0 upstream. If an IRQ is setup using __setup_irq(), which is used by the request_irq() family of functions, and we are using an SMP kernel then the affinity of the IRQ will be set via setup_affinity() immediately after the IRQ is enabled. This call to gic_set_affinity() will lead to the interrupt being mapped to a VPE. However there are other ways to use IRQs which don't cause affinity to be set, for example if it is used to chain to another IRQ controller with irq_set_chained_handler_and_data(). The irq_set_chained_handler_and_data() code path will enable the IRQ, but will not trigger a call to gic_set_affinity() and in this case nothing will map the interrupt to a VPE, meaning that the interrupt is never received. Fix this by implementing the activate operation for the GIC device IRQ domain, using gic_shared_irq_domain_map() to map the interrupt to the correct pin of cpu 0.

irqchip/mips-gic: Cleanup chip and handler setup

2016-09-15T06:20:29+00:00

commit 6a33fa2b87513fee44cb8f0cd17b1acd6316bc6b upstream. gic_shared_irq_domain_map() is called from gic_irq_domain_alloc() where the wrong chip has been set, and is then overwritten. Tidy this up by setting the correct chip the first time, and setting the handle_level_irq handler from gic_irq_domain_alloc() too. gic_shared_irq_domain_map() is also called from gic_irq_domain_map(), which now calls irq_set_chip_and_handler() to retain its previous behaviour. This patch prepares for a follow-on which will call gic_shared_irq_domain_map() from a callback where the lock on the struct irq_desc is held, which without this change would cause the call to irq_set_chip_and_handler() to lead to a deadlock.
