2016-04-05i40evf: Add additional check for resetMitch Williams1-0/+2
If the driver happens to read a register during the time in which the device is undergoing reset, it will receive a value of 0xdeadbeef instead of a valid value. Unfortunately, the driver may misinterpret this as a valid value, especially if it's just looking for individual bits. Add an explicit check for this value when we are looking for admin queue errors, and trigger reset recovery if we find it.

Resources allocated for these bridges at init time cannot be later used for other purposes. While current number is supported by the device, it's mostly theoretical with regards to any real use case, which leads to poor utilization of device's resources. Solve that by reducing the number. The long term plan is to make this value (along with others) user configurable via devlink and write it to NVRAM, so that it can be used during the next init. Until then we must hardcode such values.

2016-04-05iommu/dma: Restore scatterlist offsets correctlyRobin Murphy1-2/+2
With the change to stashing just the IOVA-page-aligned remainder of the CPU-page offset rather than the whole thing, the failure path in __invalidate_sg() also needs tweaking to account for that in the case of differing page sizes where the two offsets may not be equivalent. Similarly in __finalise_sg(), lest the architecture-specific wrappers later get the wrong address for cache maintenance on sync or unmap.

2016-04-05kvm: x86: make lapic hrtimer pinnedLuiz Capitulino1-4/+4
When a vCPU runs on a nohz_full core, the hrtimer used by the lapic emulation code can be migrated to another core. When this happens, it's possible to observe milisecond latency when delivering timer IRQs to KVM guests. The huge latency is mainly due to the fact that apic_timer_fn() expects to run during a kvm exit. It sets KVM_REQ_PENDING_TIMER and let it be handled on kvm entry. However, if the timer fires on a different core, we have to wait until the next kvm exit for the guest to see KVM_REQ_PENDING_TIMER set. This problem became visible after commit 9642d18ee. This commit changed the timer migration code to always attempt to migrate timers away from nohz_full cores. While it's discussable if this is correct/desirable (I don't think it is), it's clear that the lapic emulation code has a requirement on firing the hrtimer in the same core where it was started. This is achieved by making the hrtimer pinned. Lastly, note that KVM has code to migrate timers when a vCPU is scheduled to run in different core. However, this forced migration may fail. When this happens, we can have the same problem. If we want 100% correctness, we'll have to modify apic_timer_fn() to cause a kvm exit when it runs on a different core than the vCPU. Not sure if this is possible. Here's a reproducer for the issue being fixed: 1. Set all cores but core0 to be nohz_full cores 2. Start a guest with a single vCPU 3. Trace apic_timer_fn() and kvm_inject_apic_timer_irqs() You'll see that apic_timer_fn() will run in core0 while kvm_inject_apic_timer_irqs() runs in a different core. If you get both on core0, try running a program that takes 100% of the CPU and pin it to core0 to force the vCPU out.

2016-04-05iommu: provide of_xlate pointer unconditionallyArnd Bergmann1-2/+0
iommu drivers that support the standard DT bindings use a of_xlate callback pointer, but that is only part of struct iommu_ops when CONFIG_OF_IOMMU is enabled, leading to build errors in randconfig builds when that is not provided: drivers/iommu/mtk_iommu.c:497:2: error: unknown field 'of_xlate' specified in initializer .of_xlate = mtk_iommu_of_xlate, ^ drivers/iommu/mtk_iommu.c:497:14: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] .of_xlate = mtk_iommu_of_xlate, ^~~~~~~~~~~~~~~~~~ drivers/iommu/mtk_iommu.c:497:14: note: (near initialization for 'mtk_iommu_ops.domain_get_attr') We can work around it by adding more #ifdefs in each driver, but it seems nicer to just allow setting the pointer even if it is unused. This makes the driver code look nicer, and it gives better compile-time coverage when test building on other architectures.

2016-04-05mac80211: minstrel_ht: improve sample rate skip logicFelix Fietkau1-7/+16
There were a few issues that were slowing down the process of finding the optimal rate, especially on devices with multi-rate retry limitations: When max_tp_rate[0] was slower than max_tp_rate[1], the code did not sample max_tp_rate[1], which would often allow it to switch places with max_tp_rate[0] (e.g. if only the first sampling attempts were bad, but the rate is otherwise good). Also, sample attempts of rates between max_tp_rate[0] and [1] were being ignored in this case, because the code only checked if the rate was slower than [1]. Fix this by checking against the fastest / second fastest max_tp_rate instead of assuming a specific order between the two. In my tests this patch significantly reduces the time until minstrel_ht finds the optimal rate right after assoc Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Clear WLAN_STA_SP manually if a frame that was polled during the SP is queued because of a starting A-MPDU session.

If we try to start an A-MPDU session while the peer is sleeping and polling frames with U-APSD, we may have frames that will be buffered by ieee80211_tx_prep_agg. These frames have IEEE80211_TX_CTL_NO_PS_BUFFER set since they are sent to a sleeping client and possibly IEEE80211_TX_STATUS_EOSP. If the frame is buffered, we need clear these two flags since they will be re-sent after the move to HT_AGG_STATE_OPERATIONAL state which is very likely to happen after the SP ends.

2016-04-05mac80211: fix parsing of 40Mhz in injected radiotap headerSven Eckelmann1-2/+3
The MCS bandwidth part of the radiotap header is 2 bits wide. The full 2 bit have to compared against IEEE80211_RADIOTAP_MCS_BW_40 and not only if the first bit is set. Otherwise IEEE80211_RADIOTAP_MCS_BW_40 can be confused with IEEE80211_RADIOTAP_MCS_BW_20U.

2016-04-05nl80211: add feature for BSS selection supportArend van Spriel4-0/+204
Introducing a new feature that the driver can use to indicate the driver/firmware supports configuration of BSS selection criteria upon CONNECT command. This can be useful when multiple BSS-es are found belonging to the same ESS, ie. Infra-BSS with same SSID. The criteria can then be used to offload selection of a preferred BSS.

2016-04-05mac80211: synchronize driver rx queues before removing a stationSara Sharon4-1/+40
Some devices, like iwlwifi, have RSS queues. This may cause a situation where a disassociation is handled in control path and results in station removal while there are prior RX frames that were still not processed in other queues. When they will be processed the station will be gone, and the frames will be dropped. Add a synchronization interface to avoid that. When driver returns from the synchronization mac80211 may remove the station.

2016-04-05mac80211: mesh: convert path table to rhashtableBob Copeland4-575/+259
In the time since the mesh path table was implemented as an RCU-traversable, dynamically growing hash table, a generic RCU hashtable implementation was added to the kernel. Switch the mesh path table over to rhashtable to remove some code and also gain some features like automatic shrinking.
