2019-04-10x86/perf/amd: Remove need to check "running" bit in NMI handlerLendacky, Thomas
Spurious interrupt support was added to perf in the following commit, almost a decade ago: 63e6be6d98e1 ("perf, x86: Catch spurious interrupts after disabling counters") The two previous patches (resolving the race condition when disabling a PMC and NMI latency mitigation) allow for the removal of this older spurious interrupt support. Currently in x86_pmu_stop(), the bit for the PMC in the active_mask bitmap is cleared before disabling the PMC, which sets up a race condition. This race condition was mitigated by introducing the running bitmap. That race condition can be eliminated by first disabling the PMC, waiting for PMC reset on overflow and then clearing the bit for the PMC in the active_mask bitmap. The NMI handler will not re-enable a disabled counter. If x86_pmu_stop() is called from the perf NMI handler, the NMI latency mitigation support will guard against any unhandled NMI messages.

2019-04-09Bluetooth: btusb: request wake pin with NOAUTOENBrian Norris
Badly-designed systems might have (for example) active-high wake pins that default to high (e.g., because of external pull ups) until they have an active firmware which starts driving it low. This can cause an interrupt storm in the time between request_irq() and disable_irq(). We don't support shared interrupts here, so let's just pre-configure the interrupt to avoid auto-enabling it.

2019-04-09net/mlx5e: Switch to Toeplitz RSS hash by defaultKonstantin Khlebnikov
Although XOR hash function can perform very well on some special use cases, to align with all drivers, mlx5 driver should use Toeplitz hash by default. Toeplitz is more stable for the general use case and it is more standard and reliable. On top of that, since XOR (MLX5_RX_HASH_FN_INVERTED_XOR8) gives only a repeated 8 bits pattern. When used for udp tunneling RSS source port manipulation it results in fixed source port, which will cause bad RSS spread.

2019-04-09Revert "net/mlx5e: Enable reporting checksum unnecessary also for L3 packets"Or Gerlitz
This reverts commit b820e6fb0978f9c2ac438c199d2bb2f35950e9c9. Prior the commit we are reverting, checksum unnecessary was only set when both the L3 OK and L4 OK bits are set on the CQE. This caused packets of IP protocols such as SCTP which are not dealt by the current HW L4 parser (hence the L4 OK bit is not set, but the L4 header type none bit is set) to go through the checksum none code, where currently we wrongly report checksum unnecessary for them, a regression. Fix this by a revert. Note that on our usual track we report checksum complete, so the revert isn't expected to have any notable performance impact. Also, when we are not on the checksum complete track, the L4 protocols for which we report checksum none are not high performance ones, we will still report checksum unnecessary for UDP/TCP.

2019-04-09net/mlx5e: Rx, Fixup skb checksum for packets with tail paddingSaeed Mahameed
When an ethernet frame with ip payload is padded, the padding octets are not covered by the hardware checksum. Prior to the cited commit, skb checksum was forced to be CHECKSUM_NONE when padding is detected. After it, the kernel will try to trim the padding bytes and subtract their checksum from skb->csum. In this patch we fixup skb->csum for any ip packet with tail padding of any size, if any padding found. FCS case is just one special case of this general purpose patch, hence, it is removed.

Restore SW_CRYPTO_CONTROL operation on AP_VLAN interfaces for unicast keys, the original override was intended to be done for group keys as those are treated specially by mac80211 and would always have been rejected. Now the situation is that AP_VLAN support must be enabled by the driver if it can support it (meaning it can support software crypto GTK TX). Thus, also simplify the code - if we get here with AP_VLAN and non- pairwise key, software crypto must be used (driver doesn't know about the interface) and can be used (driver must've advertised AP_VLAN if it also uses SW_CRYPTO_CONTROL).

2019-04-09ACPICA: Namespace: remove address node from global list after method terminationErik Schmauss
ACPICA commit b233720031a480abd438f2e9c643080929d144c3 ASL operation_regions declare a range of addresses that it uses. In a perfect world, the range of addresses should be used exclusively by the AML interpreter. The OS can use this information to decide which drivers to load so that the AML interpreter and device drivers use different regions of memory. During table load, the address information is added to a global address range list. Each node in this list contains an address range as well as a namespace node of the operation_region. This list is deleted at ACPI shutdown. Unfortunately, ASL operation_regions can be declared inside of control methods. Although this is not recommended, modern firmware contains such code. New module level code changes unintentionally removed the functionality of adding and removing nodes to the global address range list. A few months ago, support for adding addresses has been re- implemented. However, the removal of the address range list was missed and resulted in some systems to crash due to the address list containing bogus namespace nodes from operation_regions declared in control methods. In order to fix the crash, this change removes dynamic operation_regions after control method termination.

2019-04-08drm/i915: Get power refs in encoder->get_power_domains()Imre Deak
Push getting the reference for the encoders' power domains into the encoder get_power_domains() hook instead of doing this from the caller. This way the encoder can store away the corresponding wakerefs. This fixes the DSI encoder disabling, which didn't release these power references it acquired during HW state readout. Note that longtime ownership for the corresponding wakerefs can be thus acquired / released in two ways. Nevertheless there is always only one owner for them: After HW readout (booting/system resume): - encoder->get_power_domains() acquires - encoder->disable*() releases After a modeset (calling intel_atomic_commit()): - encoder->enable*() acquires - encoder->disable*() releases * can be any of the encoder enable/disable hooks. v2: - Check that the DSI io_wakerefs are unset both during encoder HW readout and enabling.

2019-04-08bnxt_en: Improve RX consumer index validity check.Michael Chan
There is logic to check that the RX/TPA consumer index is the expected index to work around a hardware problem. However, the potentially bad consumer index is first used to index into an array to reference an entry. This can potentially crash if the bad consumer index is beyond legal range. Improve the logic to use the consumer index for dereferencing after the validity check and log an error message.

2019-04-08net: macb driver, check for SKBTX_HW_TSTAMPPaul Thomas
Make sure SKBTX_HW_TSTAMP (i.e. SOF_TIMESTAMPING_TX_HARDWARE) has been enabled for this skb. It does fix the issue where normal socks that aren't expecting a timestamp will not wake up on select, but when a user does want a SOF_TIMESTAMPING_TX_HARDWARE it does work.

2019-04-08Merge branch 'ethtool-fix-use-of-SPEED_UNKNOWN-constant'David S. Miller
Michael Zhivich says: ==================== ethtool: fix use of SPEED_UNKNOWN constant This patch series addresses 2 related issues: 1. ethtool_validate_speed() triggers a "signed-unsigned comparison" warning due to type difference of SPEED_UNKNOWN constant (int) and argument to ethtool_validate_speed (__u32). 2. some drivers use u16 storage for SPEED_UNKNOWN constant, resulting in value truncation and thus failure to test against SPEED_UNKNOWN correctly. This revised series addresses several feedback comments: - split up the patch in to series - do not unnecessarily change drivers that use "int" storage for speed values ==================== Signed-off-by: David S.

2019-04-08qlogic: qlcnic: fix use of SPEED_UNKNOWN ethtool constantMichael Zhivich
qlcnic driver uses u16 to store SPEED_UKNOWN ethtool constant, which is defined as -1, resulting in value truncation and thus incorrect test results against SPEED_UNKNOWN. For example, the following test will print "False": u16 speed = SPEED_UNKNOWN; if (speed == SPEED_UNKNOWN) printf("True"); else printf("False"); Change storage of speed to use u32 to avoid this issue.

2019-04-08ethtool: avoid signed-unsigned comparison in ethtool_validate_speed()Michael Zhivich
When building C++ userspace code that includes ethtool.h with "-Werror -Wall", g++ complains about signed-unsigned comparison in ethtool_validate_speed() due to definition of SPEED_UNKNOWN as -1. Explicitly cast SPEED_UNKNOWN to __u32 to match type of ethtool_validate_speed() argument. Signed-off-by: Michael Zhivich <mzhivich@akamai.com> Signed-off-by: David S. Miller <davem@davemloft.net>
