* Add to lm75_data kind field to store the kind of device the driver is working with. * Add an structure to store the configuration parameters of all the supported devices. * Delete resolution_limits from lm75_data and include them in the structure described above. * Add a pointer to the configuration parameters structure to be used as a reference to obtain the parameters. * Delete switch-case approach to get the device configuration parameters. * The structure is cleaner and easier to maintain.

2019-09-03hwmon: w83795: Fan control option isn't that dangerousJean Delvare
I have been using SENSORS_W83795_FANCTRL for several years and never had any problem. When the driver was added, I had not tested that part of the driver yet so I wanted to be super cautious, but time has shown that it works just fine. In the long run I even believe that we should drop the option and enable the feature unconditionally. It doesn't do anything until the user explicitly starts twiddling with sysfs attributes anyway.

2019-09-03hwmon: (acpi_power_meter) Change log level for 'unsafe software power cap'Wang Shenran
At boot time, the acpi_power_meter driver logs the following error level message: "Ignoring unsafe software power cap". Having read about it from a few sources, it seems that the error message can be quite misleading. While the message can imply that Linux is ignoring the fact that the system is operating in potentially dangerous conditions, the truth is the driver found an ACPI_PMC object that supports software power capping. The driver simply decides not to use it, perhaps because it doesn't support the object. The best solution is probably changing the log level from error to warning. All sources I have found, regarding the error, have downplayed its significance. There is not much of a reason for it to be on error level, while causing potential confusions or misinterpretations.

2019-09-03hwmon: (k10temp) Add support for AMD family 17h, model 70h CPUsMarcel Bocu
It would seem like model 70h is behaving in the same way as model 30h, so let's just add the new F3 PCI ID to the list of compatible devices. Unlike previous Ryzen/Threadripper, Ryzen gen 3 processors do not need temperature offsets anymore. This has been reported in the press and verified on my Ryzen 3700X by checking that the idle temperature reported by k10temp is matching the temperature reported by the firmware. Vicki Pfau sent an identical patch after I checked that no-one had written this patch. I would have been happy about dropping my patch but unlike for his patch series, I had already Cc:ed the x86 people and they already reviewed the changes. Since Vicki has not answered to any email after his initial series, let's assume she is on vacation and let's avoid duplication of reviews from the maintainers and merge my series. To acknowledge Vicki's anteriority, I added her S-o-b to the patch. v2, suggested by Guenter Roeck and Brian Woods: - rename from 71h to 70h Signed-off-by: Vicki Pfau <vi@endrift.com> Signed-off-by: Marcel Bocu <marcel.p.bocu@gmail.com> Tested-by: Marcel Bocu <marcel.p.bocu@gmail.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Cc: "H.

2019-09-03x86/amd_nb: Add PCI device IDs for family 17h, model 70hMarcel Bocu
The AMD Ryzen gen 3 processors came with a different PCI IDs for the function 3 & 4 which are used to access the SMN interface. The root PCI address however remained at the same address as the model 30h. Adding the F3/F4 PCI IDs respectively to the misc and link ids appear to be sufficient for k10temp, so let's add them and follow up on the patch if other functions need more tweaking.

2019-09-03Revert "mmc: core: do not retry CMD6 in __mmc_switch()"Jan Kaisrlik
Turns out the commit 3a0681c7448b ("mmc: core: do not retry CMD6 in __mmc_switch()") breaks initialization of a Toshiba THGBMNG5 eMMC card, when using the meson-gx-mmc.c driver on a custom board based on Amlogic A113D. The CMD6 that switches the card into HS200 mode is then one that fails and according to the below printed messages from the log: [ 1.648951] mmc0: mmc_select_hs200 failed, error -84 [ 1.648988] mmc0: error -84 whilst initialising MMC card After some analyze, it turns out that adding a delay of ~5ms inside mmc_select_bus_width() but after mmc_compare_ext_csds() has been executed, also fixes the problem. Adding yet some more debug code, trying to figure out if potentially the card could be in a busy state, both by using CMD13 and ->card_busy() ops concluded that this was not the case. Therefore, let's simply revert the commit that dropped support for retrying of CMD6, as this also fixes the problem.

2019-09-03rsi: fix a double free bug in rsi_91x_deinit()Hui Peng
`dev` (struct rsi_91x_usbdev *) field of adapter (struct rsi_91x_usbdev *) is allocated and initialized in `rsi_init_usb_interface`. If any error is detected in information read from the device side, `rsi_init_usb_interface` will be freed. However, in the higher level error handling code in `rsi_probe`, if error is detected, `rsi_91x_deinit` is called again, in which `dev` will be freed again, resulting double free. This patch fixes the double free by removing the free operation on `dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also used in `rsi_disconnect`, in that code path, the `dev` field is not (and thus needs to be) freed. This bug was found in v4.19, but is also present in the latest version of kernel. Fixes CVE-2019-15504.

2019-09-03spi: spi-fsl-dspi: Fix race condition in TCFQ/EOQ interruptVladimir Oltean
When the driver is working in TCFQ/EOQ mode (i.e. interacts with the SPI controller's FIFOs directly) the following sequence of operations happens: - The first byte of the tx buffer gets pushed to the TX FIFO (dspi->len gets decremented). This triggers the train of interrupts that handle the rest of the bytes. - The dspi_interrupt handles a TX confirmation event. It reads the newly available byte from the RX FIFO, checks the dspi->len exit condition, and if there's more to be done, it kicks off the next interrupt in the train by writing the next byte to the TX FIFO. Now the problem is that the wait queue is woken up one byte too early, because dspi->len becomes 0 as soon as the byte has been pushed into the TX FIFO. Its interrupt has not yet been processed and the RX byte has not been put from the FIFO into the buffer. Depending on the timing of the wait queue wakeup vs the handling of the last dspi_interrupt, it can happen that the main SPI message pump thread has already returned back into the spi_device driver. When the rx buffer is on stack (which it can be, because in this mode, the DSPI doesn't do DMA), the last interrupt will perform a memory write into an rx buffer that has been freed. This manifests as stack corruption. The solution is to only wake up the wait queue when dspi_rxtx says so, i.e. after it has processed the last TX confirmation interrupt and collected the last RX byte.

2019-09-03sched/fair: Don't assign runtime for throttled cfs_rqLiangyan
do_sched_cfs_period_timer() will refill cfs_b runtime and call distribute_cfs_runtime to unthrottle cfs_rq, sometimes cfs_b->runtime will allocate all quota to one cfs_rq incorrectly, then other cfs_rqs attached to this cfs_b can't get runtime and will be throttled. We find that one throttled cfs_rq has non-negative cfs_rq->runtime_remaining and cause an unexpetced cast from s64 to u64 in snippet: distribute_cfs_runtime() { runtime = -cfs_rq->runtime_remaining + 1; } The runtime here will change to a large number and consume all cfs_b->runtime in this cfs_b period. According to Ben Segall, the throttled cfs_rq can have account_cfs_rq_runtime called on it because it is throttled before idle_balance, and the idle_balance calls update_rq_clock to add time that is accounted to the task. This commit prevents cfs_rq to be assgined new runtime if it has been throttled until that distribute_cfs_runtime is called.

When the 'start' parameter is >= 0xFF000000 on 32-bit systems, or >= 0xFFFFFFFF'FF000000 on 64-bit systems, fill_gva_list() gets into an infinite loop. With such inputs, 'cur' overflows after adding HV_TLB_FLUSH_UNIT and always compares as less than end. Memory is filled with guest virtual addresses until the system crashes.
