2018-03-29dm: fix dropped return code from dm_get_bdev_for_ioctlMike Snitzer
dm_get_bdev_for_ioctl()'s return of 0 or 1 must be the result from prepare_ioctl (1 means the ioctl was issued to a partition, 0 means it wasn't). Unfortunately commit 519049afea ("dm: use blkdev_get rather than bdgrab when issuing pass-through ioctl") reused the variable 'r' to store the return from blkdev_get() that follows prepare_ioctl() -- whereby dropping prepare_ioctl()'s result on the floor. This can lead to an ioctl or persistent reservation being issued to a partition going unnoticed, which implies the extra permission check for CAP_SYS_RAWIO is skipped. Fix this by using a different variable to store blkdev_get()'s return.

2018-03-28RDMA/ucma: Introduce safer rdma_addr_size() variantsRoland Dreier
There are several places in the ucma ABI where userspace can pass in a sockaddr but set the address family to AF_IB. When that happens, rdma_addr_size() will return a size bigger than sizeof struct sockaddr_in6, and the ucma kernel code might end up copying past the end of a buffer not sized for a struct sockaddr_ib. Fix this by introducing new variants int rdma_addr_size_in6(struct sockaddr_in6 *addr); int rdma_addr_size_kss(struct __kernel_sockaddr_storage *addr); that are type-safe for the types used in the ucma ABI and return 0 if the size computed is bigger than the size of the type passed in. We can use these new variants to check what size userspace has passed in before copying any addresses.

2018-03-27qede: Fix barrier usage after tx doorbell write.Manish Chopra
Since commit c5ad119fb6c09b0297446be05bd66602fa564758 ("net: sched: pfifo_fast use skb_array") driver is exposed to an issue where it is hitting NULL skbs while handling TX completions. Driver uses mmiowb() to flush the writes to the doorbell bar which is a write-combined bar, however on x86 mmiowb() does not flush the write combined buffer. This patch fixes this problem by replacing mmiowb() with wmb() after the write combined doorbell write so that writes are flushed and synchronized from more than one processor.

We tried to remove vq poll from wait queue, but do not check whether or not it was in a list before. This will lead double free. Fixing this by switching to use vhost_poll_stop() which zeros poll->wqh after removing poll from waitqueue to make sure it won't be freed twice.

2018-03-27net/mlx4_en: Fix mixed PFC and Global pause user control requestsEran Ben Elisha
Global pause and PFC configuration should be mutually exclusive (i.e. only one of them at most can be set). However, once PFC was turned off, driver automatically turned Global pause on. This is a bug. Fix the driver behaviour to turn off PFC/Global once the user turned the other on. This also fixed a weird behaviour that at a current time, the profile had both PFC and global pause configuration turned on, which is Hardware-wise impossible and caused returning false positive indication to query tools. In addition, fix error code when setting global pause or PFC to change metadata only upon successful change. Also, removed useless debug print.

2018-03-27r8169: fix setting driver_data after register_netdevHeiner Kallweit
pci_set_drvdata() is called only after registering the net_device, therefore we could run into a NPE if one of the functions using driver_data is called before it's set. Fix this by calling pci_set_drvdata() before registering the net_device. This fix is a candidate for stable. As far as I can see the bug has been there in kernel version 3.2 already, therefore I can't provide a reference which commit is fixed by it. The fix may need small adjustments per kernel version because due to other changes the label which is jumped to if register_netdev() fails has changed over time.

2018-03-27drm/i915: Fix hibernation with ACPI S0 target stateImre Deak
After commit dd9f31c7a3887950cbd0d49eb9d43f7a1518a356 Author: Imre Deak <imre.deak@intel.com> Date: Wed Aug 16 17:46:07 2017 +0300 drm/i915/gen9+: Set same power state before hibernation image save/restore during hibernation/suspend the power domain functionality got disabled, after which resume could leave it incorrectly disabled if the ACPI target state was S0 during suspend and i915 was not loaded by the loader kernel. This was caused by not considering if we resumed from hibernation as the condition for power domains reiniting. Fix this by simply tracking if we suspended power domains during system suspend and reinit power domains accordingly during resume. This will result in reiniting power domains always when resuming from hibernation, regardless of the platform and whether or not i915 is loaded by the loader kernel. The reason we didn't catch this earlier is that the enabled/disabled state of power domains during PMSG_FREEZE/PMSG_QUIESCE is platform and kernel config dependent: on my SKL the target state is S4 during PMSG_FREEZE and (with the driver loaded in the loader kernel) S0 during PMSG_QUIESCE. On the reporter's machine it's S0 during PMSG_FREEZE but (contrary to this) power domains are not initialized during PMSG_QUIESCE since i915 is not loaded in the loader kernel, or it's loaded but without the DMC firmware being available.

2018-03-27drm/i915/execlists: Use a locked clear_bit() for synchronisation with interruptChris Wilson
We were relying on the uncached reads when processing the CSB to provide ourselves with the serialisation with the interrupt handler (so we could detect new interrupts in the middle of processing the old one). However, in commit 767a983ab255 ("drm/i915/execlists: Read the context-status HEAD from the HWSP") those uncached reads were eliminated (on one path at least) and along with them our serialisation. The result is that we would very rarely miss notification of a new interrupt and leave a context-switch unprocessed, hanging the GPU.

2018-03-27drm/i915/dp: Write to SET_POWER dpcd to enable MST hub.Dhinakaran Pandiyan
If bios sets up an MST output and hardware state readout code sees this is an SST configuration, when disabling the encoder we end up calling ->post_disable_dp() hook instead of the MST version. Consequently, we write to the DP_SET_POWER dpcd to set it D3 state. Further along when we try enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up the MST hub. This results in continuous link training failures which keep the system busy delaying boot. We could identify bios MST boot discrepancy and handle it accordingly but a simple way to solve this is to write to the DP_SET_POWER dpcd for MST too.

When mlx5_core is loaded it is expected to sync ports with all vxlan devices so it can support vxlan encap/decap. This is done via udp_tunnel_get_rx_info(). Currently this call is set in mlx5e_nic_enable() and if the netdev is not in NETREG_REGISTERED state it will not be called. Normally on load the netdev state is not NETREG_REGISTERED so udp_tunnel_get_rx_info() will not be called. Moving udp_tunnel_get_rx_info() to mlx5e_open() so it will be called on netdev UP event and allow encap/decap.

2018-03-26net/mlx5e: Avoid using the ipv6 stub in the TC offload neigh update pathOr Gerlitz
Currently we use the global ipv6_stub var to access the ipv6 global nd table. This practice gets us to troubles when the stub is only partially set e.g when ipv6 is loaded under the disabled policy. In this case, as of commit 343d60aada5a ("ipv6: change ipv6_stub_impl.ipv6_dst_lookup to take net argument") the stub is not null, but stub->nd_tbl is and we crash. As we can access the ipv6 nd_tbl directly, the fix is just to avoid the reference through the stub. There is one place in the code where we issue ipv6 route lookup and keep doing it through the stub, but that mentioned commit makes sure we get -EAFNOSUPPORT from the stack.

2018-03-26net/mlx5e: Fix memory usage issues in offloading TC flowsJianbo Liu
For NIC flows, the parsed attributes are not freed when we exit successfully from mlx5e_configure_flower(). There is possible double free for eswitch flows. If error is returned from rhashtable_insert_fast(), the parse attrs will be freed in mlx5e_tc_del_flow(), but they will be freed again before exiting mlx5e_configure_flower(). To fix both issues we do the following: (1) change the condition that determines if to issue the free call to check if this flow is NIC flow, or it does not have encap action. (2) reorder the code such that that the check and free calls are done before we attempt to add into the hash table.

Add check of coalescing parameters received through ethtool are within range of values supported by the HW. Driver gets the coalescing rx/tx-usecs and rx/tx-frames as set by the users through ethtool. The ethtool support up to 32 bit value for each. However, mlx5 modify cq limits the coalescing time parameter to 12 bit and coalescing frames parameters to 16 bits. Return out of range error if user tries to set these parameters to higher values.
