2016-09-13netfilter: synproxy: Check oom when adding synproxy and seqadj ct extensionsGao Feng
When memory is exhausted, nfct_seqadj_ext_add may fail to add the synproxy and seqadj extensions. The function nf_ct_seqadj_init doesn't check if get valid seqadj pointer by the nfct_seqadj. Now drop the packet directly when fail to add seqadj extension to avoid dereference NULL pointer in nf_ct_seqadj_init from init_conntrack().

2016-09-12svcauth_gss: Revert 64c59a3726f2 ("Remove unnecessary allocation")Chuck Lever
rsc_lookup steals the passed-in memory to avoid doing an allocation of its own, so we can't just pass in a pointer to memory that someone else is using. If we really want to avoid allocation there then maybe we should preallocate somwhere, or reference count these handles. For now we should revert.

Change nvme-rdma to use the IB Client API to detect device removal. This has the wonderful benefit of being able to blow away all the ib/rdma_cm resources for the device being removed. No craziness about not destroying the cm_id handling the event. No deadlocks due to broken iw_cm/rdma_cm/iwarp dependencies. And no need to have a bound cm_id around during controller recovery/reconnect to catch device removal events. We don't use the device_add aspect of the ib_client service since we only want to create resources for an IB device if we have a target utilizing that device.

2016-09-12nvme-rdma: add DELETING queue flagSagi Grimberg
When we get a surprise disconnect from the target we queue a periodic reconnect (which is the sane thing to do...). We only move the queues out of CONNECTED when we retry to reconnect (after 10 seconds in the default case) but we stop the blk queues immediately so we are not bothered with traffic from now on. If delete() is kicking off in this period the queues are still in CONNECTED state. Part of the delete sequence is trying to issue ctrl shutdown if the admin queue is CONNECTED (which it is!). This request is issued but stuck in blk-mq waiting for the queues to start again. This might be the one preventing us from forward progress... The patch separates the queue flags to CONNECTED and DELETING. Now we will move out of CONNECTED as soon as error recovery kicks in (before stopping the queues) and DELETING is on when we start the queue deletion. Signed-off-by: Sagi Grimberg <sagi@grimberg.me>

2016-09-12drm: Move property validation to a helper, v2.Maarten Lankhorst
Property lifetimes are equal to the device lifetime, so the separate drm_property_find is not needed. The pointer can be retrieved from the properties member, which saves us some locking and a extra lookup. The lifetime for properties is until the device is destroyed, which happens late in the device unload path. kms_atomic is also testing for invalid properties which returns -ENOENT, to be consistent return -ENOENT for valid properties that don't appear on the object property list. Changes since v1: - Return -ENOENT for invalid properties to make kms_atomic pass. - Change commit message slightly to take this into account.

2016-09-12ARM: pxa/lubbock: add pcmcia clockRussell King
Add the required PCMCIA clock for the SA1111 "1800" device. This clock is used to compute timing information for the PCMCIA interface in the SoC device, rather than the SA1111. Hence, the provision of this clock is a convenience for the driver and does not reflect the hardware, so this must not be copied into DT.

2016-09-12ARM: locomo: fix locomo irq handlingRussell King
Accidentally booting Collie on Assabet reveals that the locomo driver incorrectly overwrites gpio-sa1100's chip data for its parent interrupt, leading to oops in sa1100_gpio_unmask() and sa1100_update_edge_regs() when "gpio: sa1100: convert to use IO accessors" is applied. Fix locomo to use the handler data rather than chip data for its parent interrupt. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2016-09-12ARM: 8612/1: LPAE: initialize cache policy correctlyStefan Agner
The cachepolicy variable gets initialized using a masked pmd value. So far, the pmd has been masked with flags valid for the 2-page table format, but the 3-page table format requires a different mask. On LPAE, this lead to a wrong assumption of what initial cache policy has been used. Later a check forces the cache policy to writealloc and prints the following warning: Forcing write-allocate cache policy for SMP This patch introduces a new definition PMD_SECT_CACHE_MASK for both page table formats which masks in all cache flags in both cases.

2016-09-12mac80211: make mpath path fixing more robustPedersen, Thomas
A fixed mpath was not quite being treated as such: 1) if a PERR frame was received, a fixed mpath was deactivated. 2) queued path discovery for fixed mpath was potentially being considered, changing mpath state. 3) other mpath flags were potentially being inherited when fixing the mpath. Just assign PATH_FIXED and SN_VALID. This solves several issues when fixing a mesh path in one direction. The reverse direction mpath should probably also be fixed, or root announcements at least be enabled.

2016-09-12ARM: sa1111: fix pcmcia suspend/resumeRussell King
SA1111 PCMCIA was broken when PCMCIA switched to using dev_pm_ops for the PCMCIA socket class. PCMCIA used to handle suspend/resume via the socket hosting device, which happened at normal device suspend/resume time. However, the referenced commit changed this: much of the resume now happens much earlier, in the noirq resume handler of dev_pm_ops. However, on SA1111, the PCMCIA device is not accessible as the SA1111 has not been resumed at _noirq time. It's slightly worse than that, because the SA1111 has already been put to sleep at _noirq time, so suspend doesn't work properly. Fix this by converting the core SA1111 code to use dev_pm_ops as well, and performing its own suspend/resume at noirq time. This fixes these errors in the kernel log: pcmcia_socket pcmcia_socket0: time out after reset pcmcia_socket pcmcia_socket1: time out after reset and the resulting lack of PCMCIA cards after a S2RAM cycle.

2016-09-12ARM: sa1111: fix pcmcia interrupt mask polarityRussell King
