2017-09-28net/mlx5e: Check encap entry state when offloading tunneled flowsVlad Buslov
Encap entries cached by the driver could be invalidated due to tunnel destination neighbour state changes. When attempting to offload a flow that uses a cached encap entry, we must check the entry validity and defer the offloading if the entry exists but not valid. When EAGAIN is returned, the flow offloading to hardware takes place by the neigh update code when the tunnel destination neighbour becomes connected.

2017-09-28net/mlx5e: Disallow TC offloading of unsupported match/action combinationsOr Gerlitz
When offloading header re-write, the HW may need to adjust checksums along the packet. For IP traffic, and a case where we are asked to modify fields in the IP header, current HW supports that only for TCP and UDP. Enforce it, in this case fail the offloading attempt for non TCP/UDP packets.

2017-09-28net/mlx5e: Fix erroneous freeing of encap header bufferPaul Blakey
In case the neighbour for the tunnel destination isn't valid, we send a neighbour update request but we free the encap header buffer. This is wrong, because we still need it for allocating a HW encap entry once the neighbour is available. Fix that by skipping freeing it if we wait for neighbour.

2017-09-27scsi: aacraid: Add a small delay after IOP resetGuilherme G. Piccoli
Commit 0e9973ed3382 ("scsi: aacraid: Add periodic checks to see IOP reset status") changed the way driver checks if a reset succeeded. Now, after an IOP reset, aacraid immediately start polling a register to verify the reset is complete. This behavior cause regressions on the reset path in PowerPC (at least). Since the delay after the IOP reset was removed by the aforementioned patch, the fact driver just starts to read a register instantly after the reset was issued (by writing in another register) "corrupts" the reset procedure, which ends up failing all the time. The issue highly impacted kdump on PowerPC, since on kdump path we proactively issue a reset in adapter (through the reset_devices kernel parameter). This patch (re-)adds a delay right after IOP reset is issued. Empirically we measured that 3 seconds is enough, but for safety reasons we delay for 5s (and since it was 30s before, 5s is still a small amount). For reference, without this patch we observe the following messages on kdump kernel boot process: [ 76.294] aacraid 0003:01:00.0: IOP reset failed [ 76.294] aacraid 0003:01:00.0: ARC Reset attempt failed [ 86.524] aacraid 0003:01:00.0: adapter kernel panic'd ff.

Currently we acknowledge errors before clearing the error status. This could cause a new error to be populated by firmware in-between the error acknowledgment and the error status clearing which would cause the second error's status to be cleared without being handled. So, clear the error status before acknowledging the errors. Also, make sure to acknowledge the error if the error status read fails.

2017-09-27bcache: use llist_for_each_entry_safe() in __closure_wake_up()Coly Li
Commit 09b3efec ("bcache: Don't reinvent the wheel but use existing llist API") replaces the following while loop by llist_for_each_entry(), - - while (reverse) { - cl = container_of(reverse, struct closure, list); - reverse = llist_next(reverse); - + llist_for_each_entry(cl, reverse, list) { closure_set_waiting(cl, 0); closure_sub(cl, CLOSURE_WAITING + 1); } This modification introduces a potential race by iterating a corrupted list. Here is how it happens. In the above modification, closure_sub() may wake up a process which is waiting on reverse list. If this process decides to wait again by calling closure_wait(), its cl->list will be added to another wait list. Then when llist_for_each_entry() continues to iterate next node, it will travel on another new wait list which is added in closure_wait(), not the original reverse list in __closure_wake_up(). It is more probably to happen on UP machine because the waked up process may preempt the process which wakes up it. Use llist_for_each_entry_safe() will fix the issue, the safe version fetch next node before waking up a process. Then the copy of next node will make sure list iteration stays on original reverse list.

2017-09-27IB/hfi1: Unsuccessful PCIe caps tuning should not fail driver loadHarish Chegondi
Failure to tune PCIe capabilities should not fail driver load. This can cause the driver load to fail on systems with any of the following: 1. HFI's parent is not root. Example: HFI card is behind a PCIe bridge. 2. HFI's parent is not PCI Express capable. In these situations, failure to tune PCIe capabilities should be logged in the system message logs but not cause the driver load to fail. This patch also ensures pcie capability word DevCtl is written only after a successful read and the capability tuning process continues even if read/write of the pcie capability word DevCtl fails.

commit 9a9b8112699d will cause core to fail UD QP from being destroyed on ipoib unload, therefore cause resources leakage. On pkey change event above patch modifies mgid before calling underlying driver to detach it from QP. Drivers' detach_mcast() will fail to find modified mgid it was never given to attach in a first place. Core qp->usecnt will never go down, so ib_destroy_qp() will fail.

2017-09-26drm/i915: always update ELD connector type after get modesJani Nikula
drm_edid_to_eld() initializes the connector ELD to zero, overwriting the ELD connector type initialized in intel_audio_codec_enable(). If userspace does getconnector and thus get_modes after modeset, a subsequent audio component i915_audio_component_get_eld() call will receive an ELD without the connector type properly set. It's fine for HDMI, but screws up audio for DP. Always set the ELD connector type at intel_connector_update_modes() based on the connector type. We can drop the connector type update from intel_audio_codec_enable(). Credits to Joseph Nuzman <jnuzman@gmail.com> for figuring this out.

2017-09-26cpufreq: dt: Fix sysfs duplicate filename creation for platform-deviceSuniel Mahesh
ti-cpufreq and cpufreq-dt-platdev drivers are registering platform-device with same name "cpufreq-dt" using platform_device_register_*() routines. This is leading to build warnings appended below. Providing hardware information to OPP framework along with the platform- device creation should be done by ti-cpufreq driver before cpufreq-dt driver comes into place. This patch add's TI am33xx, am43 and dra7 platforms (which use opp-v2 property) to the blacklist of devices in cpufreq-dt-platform driver to avoid creating platform-device twice and remove build warnings.

2017-09-26PM / OPP: Call notifier without holding opp_table->lockViresh Kumar
The notifier callbacks may want to call some OPP helper routines which may try to take the same opp_table->lock again and cause a deadlock. One such usecase was reported by Chanwoo Choi, where calling dev_pm_opp_disable() leads us to the devfreq's OPP notifier handler, which further calls dev_pm_opp_find_freq_floor() and it deadlocks. We don't really need the opp_table->lock to be held across the notifier call though, all we want to make sure is that the 'opp' doesn't get freed while being used from within the notifier chain. We can do it with help of dev_pm_opp_get/put() as well. Let's do it.
