2020-01-23PCI/AER: Initialize aer_fifoDongdong Liu
Previously we did not call INIT_KFIFO() for aer_fifo. This leads to kfifo_put() sometimes returning 0 (queue full) when in fact it is not. It is easy to reproduce the problem by using aer-inject: $ aer-inject -s :82:00.0 multiple-corr-nonfatal The content of the multiple-corr-nonfatal file is as below: AER COR RCVR HL 0 1 2 3 AER UNCOR POISON_TLP HL 4 5 6 7 Fixes: 27c1ce8bbed7 ("PCI/AER: Use kfifo for tracking events instead of reimplementing it") Link: https://lore.kernel.org/r/1579767991-103898-1-git-send-email-liudongdong3@huawei.com Signed-off-by: Dongdong Liu <liudongdong3@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

PCI error recovery will fail if any device under the Root Port doesn't have an error_detected callback. Currently only the failure result is printed, which is not enough to identify the driver that lacks the callback. Log a message to identify the device with no error_detected callback.

2020-01-23Merge branch 'next-integrity.defer-measuring-keys' into next-integrityMimi Zohar
From patch set cover letter: The IMA subsystem supports measuring asymmetric keys when the key is created or updated[1]. But keys created or updated before a custom IMA policy is loaded are currently not measured. This includes keys added, for instance, to either the .ima or .builtin_trusted_keys keyrings, which happens early in the boot process. Measuring the early boot keys, by design, requires loading a custom IMA policy. This change adds support for queuing keys created or updated before a custom IMA policy is loaded. The queued keys are processed when a custom policy is loaded. Keys created or updated after a custom policy is loaded are measured immediately (not queued). In the case when a custom policy is not loaded within 5 minutes of IMA initialization, the queued keys are freed.

2020-01-23hwmon: (pwm-fan) stop fan on shutdownAkinobu Mita
The pwm-fan driver stops the fan in suspend but leaves the fan on in shutdown. It seems strange to leave the fan on in shutdown because there is no use case in my mind and the gpio-fan driver on the other hand stops in shutdown. This change turns off the fan in shutdown. If anyone complains then we'll add an optional property to switch the behavior.

2020-01-23hwmon: Driver for disk and solid state drives with temperature sensorsGuenter Roeck
Reading the temperature of ATA drives has been supported for years by userspace tools such as smarttools or hddtemp. The downside of such tools is that they need to run with super-user privilege, that the temperatures are not reported by standard tools such as 'sensors' or 'libsensors', and that drive temperatures are not available for use in the kernel's thermal subsystem. This driver solves this problem by adding support for reading the temperature of ATA drives from the kernel using the hwmon API and by adding a temperature zone for each drive. With this driver, the hard disk temperature can be read using the unprivileged 'sensors' application: $ sensors drivetemp-scsi-1-0 drivetemp-scsi-1-0 Adapter: SCSI adapter temp1: +23.0°C or directly from sysfs: $ grep . /sys/class/hwmon/hwmon9/{name,temp1_input} /sys/class/hwmon/hwmon9/name:drivetemp /sys/class/hwmon/hwmon9/temp1_input:23000 If the drive supports SCT transport and reports temperature limits, those are reported as well. drivetemp-scsi-0-0 Adapter: SCSI adapter temp1: +27.0°C (low = +0.0°C, high = +60.0°C) (crit low = -41.0°C, crit = +85.0°C) (lowest = +23.0°C, highest = +34.0°C) The driver attempts to use SCT Command Transport to read the drive temperature. If the SCT Command Transport feature set is not available, or if it does not report the drive temperature, drive temperatures may be readable through SMART attributes. Since SMART attributes are not well defined, this method is only used as fallback mechanism. Cc: Chris Healy <cphealy@gmail.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Martin K.

2020-01-23net_sched: fix datalen for ematchCong Wang
syzbot reported an out-of-bound access in em_nbyte. As initially analyzed by Eric, this is because em_nbyte sets its own em->datalen in em_nbyte_change() other than the one specified by user, but this value gets overwritten later by its caller tcf_em_validate(). We should leave em->datalen untouched to respect their choices. I audit all the in-tree ematch users, all of those implement ->change() set em->datalen, so we can just avoid setting it twice in this case.

2020-01-23dt-bindings: timer: Use non-empty ranges in exampleDouglas Anderson
On many arm64 qcom device trees, running `make dtbs_check` yells: timer@17c20000: #size-cells:0:0: 1 was expected It appears that someone was trying to assert the fact that sub-nodes describing frames would never have a size that's more than 32-bits big. That does indeed appear to be true for all cases I could find. Currently many arm64 qcom device tree files have a #address-cells and about in commit bede7d2dc8f3 ("arm64: dts: qcom: sdm845: Increase address and size cells for soc"). That means the only way we can shrink them down is to use a non-empty ranges. Since forever it has said in "writing-bindings.txt" to "DO use non-empty 'ranges' to limit the size of child buses/devices". I guess we should start listening to it. I believe (but am not certain) that this also means that we should use "ranges" to simplify the "reg" of our sub devices by specifying an offset. Let's update the example in the bindings to make this obvious. Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Rob Herring <robh@kernel.org>

On Top of this Vlad converts the ethtool stats support in E-Swtich vports representors to use the mlx5e "stats groups" infrastructure and then applied all applicable stats to the uplink representor netdev. ==================== Signed-off-by: David S.
