2016-03-11crypto: ccp - CCP versioning supportGary R Hook
Future hardware may introduce new algorithms wherein the driver will need to manage resources for different versions of the cryptographic coprocessor. This precursor patch determines the version of the available device, and marks and registers algorithms accordingly. A structure is added which manages the version-specific data.

2016-03-11xen kconfig: don't "select INPUT_XEN_KBDDEV_FRONTEND"Arnd Bergmann
The Xen framebuffer driver selects the xen keyboard driver, so the latter will be built-in if XEN_FBDEV_FRONTEND=y. However, when CONFIG_INPUT is a loadable module, this configuration cannot work. On mainline kernels, the symbol will be enabled but not used, while in combination with a patch I have to detect such useless configurations, we get the expected link failure: drivers/input/built-in.o: In function `xenkbd_remove': xen-kbdfront.c:(.text+0x2f0): undefined reference to `input_unregister_device' xen-kbdfront.c:(.text+0x30e): undefined reference to `input_unregister_device' This removes the extra "select", as it just causes more trouble than it helps. In theory, some defconfig file might break if it has XEN_FBDEV_FRONTEND in it but not INPUT_XEN_KBDDEV_FRONTEND. The Kconfig fragment we ship in the kernel (kernel/configs/xen.config) however already enables both, and anyone using an old .config file would keep having both enabled.

2016-03-11drm/i915: Actually retry with bit-banging after GMBUS timeoutVille Syrjälä
After the GMBUS transfer times out, we set force_bit=1 and return -EAGAIN expecting the i2c core to call the .master_xfer hook again so that we will retry the same transfer via bit-banging. This is in case the gmbus hardware is somehow faulty. Unfortunately we left adapter->retries to 0, meaning the i2c core didn't actually do the retry. Let's tell the core we want one retry when we return -EAGAIN. Note that i2c-algo-bit also uses this retry count for some internal retries, so we'll end up increasing those a bit as well.

2016-03-10target: Avoid DataIN transfers for non-GOOD SAM statusNicholas Bellinger
This patch modifies existing transport_complete_*() code to avoid invoking target_core_fabric_ops->queue_data_in() driver callbacks for I/O READs with non-GOOD SAM status. Some initiators expect GOOD status when a DATA-IN payload transfer is involved, so to be safe go ahead and always invoke target_core_fabric_ops->queue_status() to generate fabric responses instead. Note this is a prerequisite for IBLOCK supporting retriable status, so SAM_STAT_BUSY + SAM_STAT_TASK_SET_FULL always generates fabric driver responses instead of initiating DataIN payload transfer when non-GOOD status is present Reviewed-by: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.de> Cc: Sagi Grimberg <sagig@mellanox.com> Cc: Andy Grover <agrover@redhat.com> Cc: Mike Christie <mchristi@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2016-03-10target/user: Introduce data_bitmap, replace data_length/data_head/data_tailSheng Yang
The data_bitmap was introduced to support asynchornization accessing of data area. We divide mailbox data area into blocks, and use data_bitmap to track the usage of data area. All the new command's data would start with a new block, and may left unusable space after it end. But it's easy to track using data_bitmap. Now we can allocate data area for asynchronization accessing from userspace, since we can track the allocation using data_bitmap. The userspace part would be the same as Maxim's previous asynchronized implementation. Signed-off-by: Sheng Yang <sheng@yasker.org> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2016-03-10iser-target: Rework connection terminationJenny Derzhavetz
When we receive an event that triggers connection termination, we have a a couple of things we may want to do: 1. In case we are already terminating, bailout early 2. In case we are connected but not bound, disconnect and schedule a connection cleanup silently (don't reinstate) 3. In case we are connected and bound, disconnect and reinstate the connection This rework fixes a bug that was detected against a mis-behaved initiator which rejected our rdma_cm accept, in this stage the isert_conn is no bound and reinstate caused a bogus dereference.
