In host mode port connection status flag is "0" when loading the driver. After loading the driver system asserts suspend which is handled by "_dwc2_hcd_suspend()" function. Before the system suspend the port connection status is "0". As result need to check the "port_connect_status" if it is "0", then skipping entering to suspend.

2021-03-26cifs: Adjust key sizes and key generation routines for AES256 encryptionShyam Prasad N
For AES256 encryption (GCM and CCM), we need to adjust the size of a few fields to 32 bytes instead of 16 to accommodate the larger keys. Also, the L value supplied to the key generator needs to be changed from to 256 when these algorithms are used. Keeping the ioctl struct for dumping keys of the same size for now. Will send out a different patch for that one.

2021-03-26perf test: Change to use bash for daemon testLeo Yan
When executing the daemon test on Arm64 and x86 with Debian (Buster) distro, both skip the test case with the log: # ./perf test -v 76 76: daemon operations : --- start --- test child forked, pid 11687 test daemon list trap: SIGINT: bad trap ./tests/shell/daemon.sh: 173: local: cpu-clock: bad variable name test child finished with -2 ---- end ---- daemon operations: Skip So the error happens for the variable expansion when use local variable in the shell script. Since Debian Buster uses dash but not bash as non-interactive shell, when execute the daemon testing, it hits a known issue for dash which was reported [1]. To resolve this issue, one option is to add double quotes for all local variables assignment, so need to change the code from: local line=`perf daemon --config ${config} -x: | head -2 | tail -1` ... to: local line="`perf daemon --config ${config} -x: | head -2 | tail -1`" But the testing script has bunch of local variables, this leads to big changes for whole script. On the other hand, the testing script asks to use the "local" feature which is bash-specific, so this patch explicitly uses "#!/bin/bash" to ensure running the script with bash. After: # ./perf test -v 76 76: daemon operations : --- start --- test child forked, pid 11329 test daemon list test daemon reconfig test daemon stop test daemon signal signal 12 sent to session 'test [11596]' signal 12 sent to session 'test [11596]' test daemon ping test daemon lock test child finished with 0 ---- end ---- daemon operations: Ok [1] https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097 Fixes: 2291bb915b55 ("perf tests: Add daemon 'list' command test") Signed-off-by: Leo Yan <leo.yan@linaro.org> Acked-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20210320104554.529213-1-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2021-03-26powerpc/mm/book3s64: Use the correct storage key value when calling H_PROTECTAneesh Kumar K.V
H_PROTECT expects the flag value to include flags: AVPN, pp0, pp1, pp2, key0-key4, Noexec, CMO Option flags This patch updates hpte_updatepp() to fetch the storage key value from the linux page table and use the same in H_PROTECT hcall. native_hpte_updatepp() is not updated because the kernel doesn't clear the existing storage key value there. The kernel also doesn't use hpte_updatepp() callback for updating storage keys. This fixes the below kernel crash observed with KUAP enabled.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 1st set of IIO/counter device support, features and cleanup in the 5.13 cycle Big set in here from Alexandru Ardelean enabling multiple buffer support. This includes providing a new directory per buffer that combines what was previously in buffer/ and scan_elements/. Old interfaces still in place for compatiblity. Note immuatable branch for scmi patches to allow for some significant rework going on in that subsystem. Merge required updating to reflect some changes in IIO. Late rebase to fix some wrong fixes tags due to some earlier rebases made necessary by messing up the immutable branch. IIO New Device Support * adi,ad5686 - Add info to support AD5673R and AD5677R * bosch,bmi088 - New driver supporting this accelerometer + gyroscope * cros_ec_mkbp - New driver for this proximity sensor that exposes a 'front' sensor. Very simple switch like device, but driver allows it to share interface with more sophisticated proximity sensors. * iio_scmi - New driver to support ARM SCMI protocol to expose underlying accelerometers and gyroscopes via this firmware interface. * st,st_magn - Add ID for IISMDC magnetometer. * ti,ads131e0 - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs Counter New Device Support * IRQ or GPIO based counter - New driver for a conceptually simple counter that uses interrupts to perform the count. Features * core - Dual buffer supprt including: Various helpers to centralize handling of bufferer related elements. Document existing and new IOCTLs Register the IIO chrdev only if it can actually be used for anything. Rework attribute group creation in the core (lots of patches) Merge buffer/ and scan_elements/ entries into one list + maintain backwards compatible set. Introduce the internal logic and IOCTL to allow multiple buffers + access to an anon FD per buffer to actually read from it. Tidy up tools/iio/iio_generic_buffer and switch to new interfaces. Update ABI docs. A few follow up fixes, unsuprising as this was a huge bit of rework. - Move common case setting of trig->parent to the core. - Provide an iio_read_channel_processed_scale() to avoid loss of precision from iio_read_channel_processed() then applying integer scale. Use it in ntc_thermistor driver in hwmon. - Allow drivers to specify labels from elsewhere than DT. Use it for bmc150 and kxcjk-1013 labels related to position on 2 in one tablets. - Document label usage for proximity and accelerometer sensors. - Some local variable renames for consistency tools - Add -a parameter to iio_event_monitor to allow autoenabling of events. * acpi_als - Add trigger support for devices that don't support notification method. * adi,ad7124 - Allow more than 8 channels. This is a complex little device, but is capable of supporting up to 16 channels if the share certain configuration settings. * hrtimer-trigger - Support sampling frequency below 1Hz. * mediatek,mt8195-auxadc - Add compatible to binding docs (always also includes mt8173) * st,stm32-adc - Enable timetamps when not using DMA. * vishay,vcnl3020 - Sampling frequency control. Cleanup and minor fixes: * treewide - Use some getter and setter functions instead of opencoding. - Set of fixes for pointless casts in various drivers. - Avoid wrong kernel-doc marking on comment blocks. - Fix various other minor kernel-doc issues shown by W=1 * core - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts. - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0 - Add unit tests for iio_format_value() * docs - Fix formatting/typos in iio_configfs.rst and buffers.rst - Add documentation of index in buffers.rst - Fix scan element description - Avoid some issues with HTML generation from ABI docs by moving duplicated defintions to more generic files. - Drop reference to long dead mailing list. * 104-quad - Remove left over deprecated IIO counter ABI. * adi,adi-axi-adc - Fix wrong bit of docs. * adi,ad5791 - Typos * adi,ad9834 - Switch to device managed functions in probe. * adi,adis* - Add and use helpers for locking to reduced duplication. * adi,adis16480 - Fix calculation of sampling frequency when using pulse per second input. * adi,adis16475 - Calculate the IMU scaled internal sampling rate and runtime depending on sysfs based configuration rather than getting from DT. Drop now unnecessary property from DT bindings doc. * cros_ec - Fix result of a series of recent changes that means extended buffer attributes turn up in the wrong place. Too complex to revert the various patches unfortunately so this is a bit messy. * fsl,mma3452 - Indentation cleanup. * hid-sensors - Size of storage needs to increase for some parts when using quaternions. - Move the get sensistivity attribute to hid-sensors-common to reduce duplication. Enable it for more device types. - Correctly handle relative sensitivity if reported that way including documenting the new ABI. * maxim,max517 - Use device managed functions in probe. * mediatek,mt6360-adc - Use asm/unaligned.h instead of directly including unaligned/be_byteshift.h * novuton,npcm-adc - Local lock instead of missusing mlock. * semtech,sx9500 - Typos * st,sensor - typo fix * st,spear-adc - Local lock instead of missusing mlock. * st,stm32-adc - Long standing HAS_IOMEM dependency fix. * st,stm32-counter - Remove left over deprecated IIO counter ABI. * ti,palmas-adc - Local lock instead of missusing mlock. * ti,tmp007 - Switch to device managed functions in probe.

2021-03-25s390/vdso: fix initializing and updating of vdso_dataHeiko Carstens
Li Wang reported that clock_gettime(CLOCK_MONOTONIC_RAW, ...) returns incorrect values when time is provided via vdso instead of system call: vdso_ts_nsec = 4484351380985507, vdso_ts.tv_sec = 4484351, vdso_ts.tv_nsec = 380985507 sys_ts_nsec = 1446923235377, sys_ts.tv_sec = 1446, sys_ts.tv_nsec = 923235377 Within the s390 specific vdso function __arch_get_hw_counter() reads tod clock steering values from the arch_data member of the passed in vdso_data structure. Problem is that only for the CS_HRES_COARSE vdso_data arch_data is initialized and gets updated. The CS_RAW specific vdso_data does not contain any valid tod_clock_steering information, which explains the different values. Fix this by initializing and updating all vdso_datas.

2021-03-25s390/vdso: fix tod_steering_delta typeHeiko Carstens
The s390 specific vdso function __arch_get_hw_counter() is supposed to consider tod clock steering. If a tod clock steering event happens and the tod clock is set to a new value __arch_get_hw_counter() will not return the real tod clock value but slowly drift it from the old delta until the returned value finally matches the real tod clock value again. Unfortunately the type of tod_steering_delta unsigned while it is supposed to be signed. It depends on if tod_steering_delta is negative or positive in which direction the vdso code drifts the clock value. Worst case is now that instead of drifting the clock slowly it will jump into the opposite direction by a factor of two. Fix this by simply making tod_steering_delta signed.

2021-03-25s390/vdso: copy tod_steering_delta value to vdso_data pageHeiko Carstens
When converting the vdso assembler code to C it was forgotten to actually copy the tod_steering_delta value to vdso_data page. Which in turn means that tod clock steering will not work correctly. Fix this by simply copying the value whenever it is updated.

2021-03-25iio: cros: unify hw fifo attributes without API changesGwendal Grignou
Commit 2e2366c2d141 ("iio: cros_ec: unify hw fifo attributes into the core file") should be reverted as it set buffer extended attributes at the wrong place. However, to revert it will requires to revert more commits: commit 165aea80e2e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()") commit 21232b4456ba ("iio: buffer: remove iio_buffer_set_attrs() helper")). and we would still have conflict with more recent development. commit ee708e6baacd ("iio: buffer: introduce support for attaching more IIO buffers") Instead, this commit reverts the first 2 commits without re-adding iio_buffer_set_attrs() and set the buffer extended attributes at the right place: 1. Instead of adding has_fw_fifo, deduct it from the configuration: - EC must support FIFO (EC_FEATURE_MOTION_SENSE_FIFO) set. - sensors send data a regular interval (accelerometer, gyro, magnetomer, barometer, light sensor). - "Legacy accelerometer" is only present on EC without FIFO, so we don't need to set buffer attributes. 2. devm_iio_triggered_buffer_setup_ext() does not need to be called when EC does not support FIFO, as there is no FIFO to manage. 3. Use devm_iio_triggered_buffer_setup_ext() when EC has a FIFO to specify the buffer extended attributes.

2021-03-25iio: kfifo: add devm_iio_triggered_buffer_setup_ext variantAlexandru Ardelean
This is similar to the {devm_}iio_triggered_buffer_setup_ext variants added via commit 5164c7889857 ("iio: triggered-buffer: add {devm_}iio_triggered_buffer_setup_ext variants"). These can be used to pass extra buffer attributes to the buffer object. This is a bit of temporary mechanism (hopefully) so that drivers that want to allocate a kfifo buffer with extra buffer attributes, don't need to include 'buffer_impl.h' directly. This can also become an API function (in it's own right, unfortunately), but it may be a little less bad vs drivers having to include 'buffer_impl.h'. So, far the drivers that want to pass buffer attributes, all have to do with some HW FIFO attributes, so there may be a chance of unifying them into IIO core somehow (as some standard API). But, until that happens, we just need to let them register their HW FIFO attributes directly (without having to let them include 'buffer_impl.h' directly).

2021-03-25iio: event_monitor: Enable events before monitoringLinus Walleij
After some painful sessions with a driver that register an enable/disable sysfs knob (gp2ap002) and manually going in and enabling the event before monitoring it: cd /sys/bus/iio/devices/iio\:device2/events # ls in_proximity_thresh_either_en # echo 1 > in_proximity_thresh_either_en I realized that it's better if the iio_event_monitor is smart enough to enable all events by itself and disable them after use, if passed the -a flag familiar from the iio_generic_buffer tool. Auto-enabling events depend on the hardware being able to handle all events at the same time which isn't necessarily the case, so a command line option is required for this.
