2017-05-22dm verity: fix no salt use caseGilad Ben-Yossef
DM-Verity has an (undocumented) mode where no salt is used. This was never handled directly by the DM-Verity code, instead working due to the fact that calling crypto_shash_update() with a zero length data is an implicit noop. This is no longer the case now that we have switched to crypto_ahash_update(). Fix the issue by introducing explicit handling of the no salt use case to DM-Verity.

2017-05-22net: Make IP alignment calulations clearer.David S. Miller
The assignmnet: ip_align = strict ? 2 : NET_IP_ALIGN; in compare_pkt_ptr_alignment() trips up Coverity because we can only get to this code when strict is true, therefore ip_align will always be 2 regardless of NET_IP_ALIGN's value.

The stingray SDHCI hardware supports ACMD12 and automatically issues after multi block transfer completed. If ACMD12 in SDHCI is disabled, spurious tx done interrupts are seen on multi block read command with below error message: Got data interrupt 0x00000002 even though no data operation was in progress. This patch uses SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 to enable ACM12 support in SDHCI hardware and suppress spurious interrupt.

2017-05-22bonding: fix accounting of active ports in 3adJarod Wilson
As of 7bb11dc9f59d and 0622cab0341c, bond slaves in a 3ad bond are not removed from the aggregator when they are down, and the active slave count is NOT equal to number of ports in the aggregator, but rather the number of ports in the aggregator that are still enabled. The sysfs spew for bonding_show_ad_num_ports() has a comment that says "Show number of active 802.3ad ports.", but it's currently showing total number of ports, both active and inactive. Remedy it by using the same logic introduced in 0622cab0341c in __bond_3ad_get_active_agg_info(), so sysfs, procfs and netlink all report the number of active ports. Note that this means that IFLA_BOND_AD_INFO_NUM_PORTS really means NUM_ACTIVE_PORTS instead of NUM_PORTS, and thus perhaps should be renamed for clarity. Lightly tested on a dual i40e lacp bond, simulating link downs with an ip link set dev <slave2> down, was able to produce the state where I could see both in the same aggregator, but a number of ports count of 1.

2017-05-22pinctrl: core: Fix warning by removing bogus codeTony Lindgren
Andre Przywara <andre.przywara@arm.com> noticed that we can get the following warning with -EPROBE_DEFER: "WARNING: CPU: 1 PID: 89 at drivers/base/dd.c:349 driver_probe_device+0x2ac/0x2e8" Let's fix the issue by removing the indices as suggested by Tejun Heo <tj@kernel.org>. All we have to do here is kill the radix tree. I probably ended up with the indices after grepping for removal of all entries using radix_tree_for_each_slot() and the first match found was gmap_radix_tree_free(). Anyways, no need for indices here, and we can just do remove all the entries using radix_tree_for_each_slot() along how the item_kill_tree() test case does.

2017-05-22drm: rcar-du: Register a completion callback with VSP1Kieran Bingham
Currently we process page flip events on every display interrupt, however this does not take into consideration the processing time needed by the VSP1 utilised in the pipeline. Register a callback with the VSP driver to obtain completion events, and track them so that we only perform page flips when the full display pipeline has completed for the frame.

2017-05-22drm: rcar-du: Arm the page flip event after queuing the page flipLaurent Pinchart
The page flip event is armed in the atomic begin handler, creating a race condition with the frame end interrupt that could send the event before the atomic operation actually completes. To avoid that, arm the event in the atomic flush handler after queuing the page flip. This change doesn't fully close the race window, as the frame end interrupt could be generated before the page flip is committed to hardware but only handled after the event is armed. However, the race window is now much smaller.

2017-05-22mtd: nand: samsung: warn about un-parseable ECC infoBrian Norris
We don't handle cases larger than 7. We probably shouldn't pretend we know the ECC step size in this case, and it's probably also good to WARN() like we do in many other similar cases.

2017-05-22mtd: nand: free vendor-specific resources in init failure pathsBrian Norris
If we fail any time after calling nand_detect(), then we don't call the vendor-specific ->cleanup() callback, and we'll leak any resources the vendor-specific code might have allocated. Mark the "fix" against the first commit that started allocating anything in ->init().

This code causes a static checker warning because it treats "i == 0" as a timeout but, because it's a post-op, the loop actually ends with "i" set to -1.

2017-05-21ext4: handle the rest of ext4_mb_load_buddy() ENOMEM errorsKonstantin Khlebnikov
I've got another report about breaking ext4 by ENOMEM error returned from ext4_mb_load_buddy() caused by memory shortage in memory cgroup. This time inside ext4_discard_preallocations(). This patch replaces ext4_error() with ext4_warning() where errors returned from ext4_mb_load_buddy() are not fatal and handled by caller: * ext4_mb_discard_group_preallocations() - called before generating ENOSPC, we'll try to discard other group or return ENOSPC into user-space. * ext4_trim_all_free() - just stop trimming and return ENOMEM from ioctl. Some callers cannot handle errors, thus __GFP_NOFAIL is used for them: * ext4_discard_preallocations() * ext4_mb_discard_lg_preallocations() Fixes: adb7ef600cc9 ("ext4: use __GFP_NOFAIL in ext4_free_blocks()") Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
