2019-09-04powerpc/tm: Fix FP/VMX unavailable exceptions inside a transactionGustavo Romero
When we take an FP unavailable exception in a transaction we have to account for the hardware FP TM checkpointed registers being incorrect. In this case for this process we know the current and checkpointed FP registers must be the same (since FP wasn't used inside the transaction) hence in the thread_struct we copy the current FP registers to the checkpointed ones. This copy is done in tm_reclaim_thread(). We use thread->ckpt_regs.msr to determine if FP was on when in userspace. thread->ckpt_regs.msr represents the state of the MSR when exiting userspace. This is setup by check_if_tm_restore_required(). Unfortunatley there is an optimisation in giveup_all() which returns early if tsk->thread.regs->msr (via local variable `usermsr`) has FP=VEC=VSX=SPE=0. This optimisation means that check_if_tm_restore_required() is not called and hence thread->ckpt_regs.msr is not updated and will contain an old value. This can happen if due to load_fp=255 we start a userspace process with MSR FP=1 and then we are context switched out. In this case thread->ckpt_regs.msr will contain FP=1. If that same process is then context switched in and load_fp overflows, MSR will have FP=0. If that process now enters a transaction and does an FP instruction, the FP unavailable will not update thread->ckpt_regs.msr (the bug) and MSR FP=1 will be retained in thread->ckpt_regs.msr. tm_reclaim_thread() will then not perform the required memcpy and the checkpointed FP regs in the thread struct will contain the wrong values. The code path for this happening is: Userspace: Kernel Start userspace with MSR FP/VEC/VSX/SPE=0 TM=1 < ----- ... tbegin bne fp instruction FP unavailable ---- > fp_unavailable_tm() tm_reclaim_current() tm_reclaim_thread() giveup_all() return early since FP/VMX/VSX=0 /* ckpt MSR not updated (Incorrect) */ tm_reclaim() /* thread_struct ckpt FP regs contain junk (OK) */ /* Sees ckpt MSR FP=1 (Incorrect) */ no memcpy() performed /* thread_struct ckpt FP regs not fixed (Incorrect) */ tm_recheckpoint() /* Put junk in hardware checkpoint FP regs */ .... < ----- Return to userspace with MSR TM=1 FP=1 with junk in the FP TM checkpoint TM rollback reads FP junk This is a data integrity problem for the current process as the FP registers are corrupted. It's also a security problem as the FP registers from one process may be leaked to another. This patch moves up check_if_tm_restore_required() in giveup_all() to ensure thread->ckpt_regs.msr is updated correctly. A simple testcase to replicate this will be posted to tools/testing/selftests/powerpc/tm/tm-poison.c Similarly for VMX. This fixes CVE-2019-15030.

2019-09-04mm/balloon_compaction: suppress allocation warningsNadav Amit
There is no reason to print warnings when balloon page allocation fails, as they are expected and can be handled gracefully. Since VMware balloon now uses balloon-compaction infrastructure, and suppressed these warnings before, it is also beneficial to suppress these warnings to keep the same behavior that the balloon had before.

2019-09-04virtio-net: lower min ring num_free for efficiency? jiang
This change lowers ring buffer reclaim threshold from 1/2*queue to budget for better performance. According to our test with qemu + dpdk, packet dropping happens when the guest is not able to provide free buffer in avail ring timely with default 1/2*queue. The value in the patch has been tested and does show better performance. Test setup: iperf3 to generate packets to guest (total 30mins, pps 400k, UDP) avg packets drop before: 2842 avg packets drop after: 360(-87.3%) Further, current code suffers from a starvation problem: the amount of work done by try_fill_recv is not bounded by the budget parameter, thus (with large queues) once in a while userspace gets blocked for a long time while queue is being refilled. Trigger refills earlier to make sure the amount of work to do is limited. Signed-off-by: jiangkidd <jiangkidd@hotmail.com> Acked-by: Jason Wang <jasowang@redhat.com> Acked-by: Michael S.

2019-09-04EDAC/mc_sysfs: Make debug messages consistentRobert Richter
Debug messages are inconsistently used in the error handlers. Some lack an error message, some are called regardless of the return status, messages for the same error are at different locations in the code depending on the error code. This happens esp. near put_device() calls. Make those debug messages more consistent. Additionally, unify the error messages to have the same terms for the same operations of the device.

This ThinkCentre machine has a new realtek codec alc222, it is not in the support list, we add it in the realtek.c then this machine can apply FIXUPs for the realtek codec. And this machine has two front mics which can't be handled by PA so far, it uses the pin 0x18 and 0x19 as the front mics, as a result the existing FIXUP ALC294_FIXUP_LENOVO_MIC_LOCATION doesn't work on this machine. Fortunately another FIXUP ALC283_FIXUP_HEADSET_MIC also can change the location for one of the two mics on this machine.

The commit 20c169aceb45 ("dmaengine: rcar-dmac: clear pertinence number of channels") forgets to clear the last channel by DMACHCLR in rcar_dmac_init() (and doesn't need to clear the first channel) if iommu is mapped to the device. So, this patch fixes it by using "channels_mask" bitfield. Note that the hardware and driver don't support more than 32 bits in DMACHCLR register anyway, so this patch should reject more than 32 channels in rcar_dmac_parse_of().

But before the slave hardware request, the slave will get an incorrect residue due to the first node used to trigger the link-list was configured as the last source address and destination address.

2019-09-03hwmon: (lm75) Support configuring the sample time for various chipsGuenter Roeck
The conversion (sample) time is configurable for several chips supported by the lm75 driver. With the necessary infrastructure in place, enable this support for all chips using the configuration register for this purpose. DS1775: Conversion time: 187.5, 375, 750, 1500 ms Sensor resolution: 9, 10, 11, 12 bit DS75, STDS75: Conversion time: 150, 300, 600, 1200 ms Sensor resolution: 9, 10, 11, 12 bit DS7505: Conversion time: 25, 50, 100, 200 ms Sensor resolution: 9, 10, 11, 12 bit MCP980[0123]: Conversion time: 75, 150, 300, 600 ms Sensor resolution: 9, 10, 11, 12 bit TMP100, TMP101: Conversion time: 75, 150, 300, 600 ms Sensor resolution: 9, 10, 11, 12 bit TMP75, TMP105, TMP175, TMP275: Conversion time: 38, 75, 150, 300 ms Sensor resolution: 9, 10, 11, 12 bit While doing this, it became obvious that the masks and values to set the converion (sample) time is similar for all those chips, and that other chips with configurable sample times will need separate code anyway. For that reason, replace the sample_set_masks and sample_clr_mask configuration parameters with a single array and with a constant. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

According to kernel hwmon sysfs-interface documentation, temperature critical max value, typically greater than corresponding temp_max values. Thus, reads the LTD_HV_HL (LTD HIGH VALUE HIGH LIMITATION) and LTD_LV_HL (LTD LOW VALUE HIGH LIMITATION) for case hwmon_temp_crit and hwmon_temp_crit_hyst.

2019-09-03hwmon: (iio_hwmon) Enable power exporting from IIOMichal Simek
There is no reason why power channel shouldn't be exported as is done for voltage, current, temperature and humidity. Power channel is available on iio ina226 driver. Sysfs IIO documentation for power attribute added by commit 7c6d5c7ee883 ("iio: Documentation: Add missing documentation for power attribute") is declaring that value is in mili-Watts but hwmon interface is expecting value in micro-Watts that's why there is a need for mili-Watts to micro-Watts conversion.
