2023-12-22netfilter: ctnetlink: support filtering by zoneFelix Huettner
conntrack zones are heavily used by tools like openvswitch to run multiple virtual "routers" on a single machine. In this context each conntrack zone matches to a single router, thereby preventing overlapping IPs from becoming issues. In these systems it is common to operate on all conntrack entries of a given zone, e.g. to delete them when a router is deleted. Previously this required these tools to dump the full conntrack table and filter out the relevant entries in userspace potentially causing performance issues. To do this we reuse the existing CTA_ZONE attribute. This was previous parsed but not used during dump and flush requests. Now if CTA_ZONE is set we filter these operations based on the provided zone. However this means that users that previously passed CTA_ZONE will experience a difference in functionality. Alternatively CTA_FILTER could have been used for the same functionality. However it is not yet supported during flush requests and is only available when using AF_INET or AF_INET6.

2023-12-21tracing: Update subbuffer with kilobytes not page orderSteven Rostedt (Google)
Using page order for deciding what the size of the ring buffer sub buffers are is exposing a bit too much of the implementation. Although the sub buffers are only allocated in orders of pages, allow the user to specify the minimum size of each sub-buffer via kilobytes like they can with the buffer size itself. If the user specifies 3 via: echo 3 > buffer_subbuf_size_kb Then the sub-buffer size will round up to 4kb (on a 4kb page size system). If they specify: echo 6 > buffer_subbuf_size_kb The sub-buffer size will become 8kb. and so on.

Add a selftest for verifying the accuracy of DAMON's access monitoring functionality. The test starts a program of artificial access pattern, monitor the access pattern using DAMON, and check if DAMON finds expected amount of hot data region (working set size) with only acceptable error rate. Note that the acceptable error rate is set with only naive assumptions and small number of tests. Hence failures of the test may not always mean DAMON is broken. Rather than that, those could be a signal to better understand the real accuracy level of DAMON in wider environments. Based on further finding, we could optimize DAMON or adjust the expectation of the test.

2023-12-20selftests/damon: implement a python module for test-purpose DAMON sysfs controlsSeongJae Park
Patch series "selftests/damon: add Python-written DAMON functionality tests", v2. DAMON exports most of its functionality via its sysfs interface. Hence most DAMON functionality tests could be implemented using the interface. However, because the interfaces require simple but multiple operations for many controls, writing all such tests from the scratch could be repetitive and time consuming. Implement a minimum DAMON sysfs control module, and a couple of DAMON functionality tests using the control module. The first test is for ensuring minimum accuracy of data access monitoring, and the second test is for finding if a previously found and fixed bug is introduced again. Note that the DAMON sysfs control module is only for avoiding duplicating code in tests. For convenient and general control of DAMON, users should use DAMON user-space tools that developed for the purpose, such as damo[1]. [1] https://github.com/damonitor/damo Patches Sequence ---------------- This patchset is constructed with five patches. The first three patches implement a Python-written test implementation-purpose DAMON sysfs control module. The implementation is incrementally done in the sequence of the basic data structure (first patch) first, kdamonds start command (second patch) next, and finally DAMOS tried bytes update command (third patch). Then two patches for implementing selftests using the module follows. The fourth patch implements a basic functionality test of DAMON for working set estimation accuracy. Finally, the fifth patch implements a corner case test for a previously found bug. This patch (of 5): Implement a python module for DAMON sysfs controls. The module is aimed to be useful for writing DAMON functionality tests in future. Nonetheless, this module is only representing a subset of DAMON sysfs files. Following commits will implement more DAMON sysfs controls.

do_run_with_thp() prepares (PMD-sized) THP memory into different states before running tests. With the introduction of multi-size THP, we would like to reuse this logic to also test those smaller THP sizes.

2023-12-20selftests/mm/khugepaged: enlighten for multi-size THPRyan Roberts
The `collapse_max_ptes_none` test was previously failing when a THP size less than PMD-size had enabled="always". The root cause is because the test faults in 1 page less than the threshold it set for collapsing. But when THP is enabled always, we "over allocate" and therefore the threshold is passed, and collapse unexpectedly succeeds. Solve this by enlightening khugepaged selftest. Add a command line option to pass in the desired THP size that should be used for all anonymous allocations. The harness will then explicitly configure a THP size as requested and modify the `collapse_max_ptes_none` test so that it faults in the threshold minus the number of pages in the configured THP size.

2023-12-20selftests/mm: support multi-size THP interface in thp_settingsRyan Roberts
Save and restore the new per-size hugepage enabled setting, if available on the running kernel. Since the number of per-size directories is not fixed, solve this as simply as possible by catering for a maximum number in the thp_settings struct (20). Each array index is the order. The value of THP_NEVER is changed to 0 so that all of these new settings default to THP_NEVER and the user only needs to fill in the ones they want to enable.

2023-12-20selftests/mm/kugepaged: restore thp settings at exitRyan Roberts
Previously, the saved thp settings would be restored upon a signal or at the natural end of the test suite. But there are some tests that directly call exit() upon failure. In this case, the thp settings were not being restored, which could then influence other tests. Fix this by installing an atexit() handler to do the actual restore. The signal handler can now just call exit() and the atexit handler is invoked.

2023-12-20selftests: secretmem: floor the memory size to the multiple of page_sizeMuhammad Usama Anjum
The "locked-in-memory size" limit per process can be non-multiple of page_size. The mmap() fails if we try to allocate locked-in-memory with same size as the allowed limit if it isn't multiple of the page_size because mmap() rounds off the memory size to be allocated to next multiple of page_size. Fix this by flooring the length to be allocated with mmap() to the previous multiple of the page_size. This was getting triggered on KernelCI regularly because of different ulimit settings which wasn't multiple of the page_size. Find logs here: https://linux.kernelci.org/test/plan/id/657654bd8e81e654fae13532/ The bug in was present from the time test was first added.

2023-12-20maple_tree: do not preallocate nodes for slot storesSidhartha Kumar
mas_preallocate() defaults to requesting 1 node for preallocation and then ,depending on the type of store, will update the request variable. There isn't a check for a slot store type, so slot stores are preallocating the default 1 node. Slot stores do not require any additional nodes, so add a check for the slot store case that will bypass node_count_gfp(). Update the tests to reflect that slot stores do not require allocations. User visible effects of this bug include increased memory usage from the unneeded node that was allocated.

2023-12-20perf maps: Add remove maps function to remove a map based on callbackIan Rogers
Removing maps wasn't being done under the write lock. Similar to maps__for_each_map(), iterate the entries but in this case remove the entry based on the result of the callback. If an entry was removed then maps_by_name() also needs updating, so add missed flush. In dso__load_kcore(), the test of map to save would always be false with REFCNT_CHECKING because of a missing RC_CHK_ACCESS/RC_CHK_EQUAL.

2023-12-20perf archive: Add new option '--unpack' to expand tarballsVeronika Molnarova
Archives generated by the command 'perf archive' have to be unpacked manually. Following the addition of option '--all' now there also exist a nested structure of tars, and after further discussion with Red Hat Global Support Services, they found a feature correctly unpacking archives of 'perf archive' convenient. Option '--unpack' of 'perf archive' unpacks archives generated by the command 'perf archive' as well as archives generated when used with option '--all'. The 'perf.data' file is placed in the current directory, while debug symbols are unpacked in '~/.debug' directory. A tar filename can be passed as an argument, and if not provided the command tries to find a viable perf.tar file for unpacking.

Minor changes to driver needed alongside new IDs. aosong,ags02ma * New driver for this volatile organic compounds sensor. bosch,bmp280 * Add BMP390 (small amount of refactoring + ID) bosch,bmi323 * New driver to support the BMI323 6-axis IMU. honeywell,hsc030pa * New driver supporting a huge number of SSC and HSC series pressure and temperature sensors. isil,isl76682 * New driver for this simple Ambient Light sensor. liteon,ltr390 * New driver for this ambient and ultraviolet light sensor. maxim,max34408 * New driver to support the MAX34408 and MAX34409 current monitoring ADCs. melexis,mlx90635 * New driver for this Infrared contactless temperature sensor. mirochip,mcp9600 * New driver for this thermocouple EMF convertor. ti,hdc3020 * New driver for this integrated relative humidity and temperature sensor. vishay,veml6075 * New driver for this UVA and UVB light sensor. General features ---------------- Device properties * Add fwnode_property_match_property_string() helper to allow matching single value property against an array of predefined strings. * Use fwnode_property_string_array_count() inside fwnode_property_match_string() instead of open coding the same. checkpatch.pl * Add exclusion of __aligned() from a warning reducing false positives on IIO drivers (and hopefully beyond) IIO Features ------------ core * New light channel modifiers for UVA and UVB. * Add IIO_CHAN_INFO_TROUGH as counterpart to IIO_CHAN_INFO_PEAK so that we can support device that keep running track of the lowest value they have seen in similar fashion to the existing peak tracking. adi,adis library * Use spi cs inactive delay even when a burst reading is performed. As it's now used every time, can centralize the handling in the SPI setup code in the driver. adi,ad2s1210 * Support for fixed-mode to this resolver driver where the A0 and A1 pins are hard wired to config mode in which case position and config must be read from appropriate config registers. * Support reset GPIO if present. adi,ad5791 * Allow configuration of presence of external amplifier in DT binding. adi,adis16400 * Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked if default delays are not quite enough for a specific board. adi,adis16475 * Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked if default delays are not quite enough for a specific board. bosch,bmp280 * Enable multiple chip IDs per family of devices. rohm,bu27008 * Add an illuminance channel calculated from RGB and IR data. Cleanup ------- Minor white space, typos and tidy up not explicitly called out. Core * Check that the available_scan_masks array passed to the IIO core by a driver is sensible by ensuring the entries are ordered so the minimum number of channels is enabled in the earlier entries (as they will be selected if sufficient for the requested channels). * Document that the available_scan_masks infrastructure doesn't currently handle masks that don't fit in a long int. * Improve intensity documentation to reflect that there is no expectation of sensible units (it's dependent on a frequency sensitivity curve) Various * Use new device_property_match_property_string() to replace open coded versions of the same thing. * Fix a few MAINTAINERS filenames. * i2c_get_match_data() and spi_get_device_match_data() pushed into more drivers reducing boilerplate handling. * Some unnecessary headers removed. * ACPI_PTR() removals. It's rarely worth using this. adi,ad7091r (early part of a series adding device support - useful in their own right) * Pass iio_dev directly an event handler rather than relying on broken use of dev_get_drvdata() as drvdata is never set in this driver. * Make sure alert is turned on. adi,ad9467 (general driver fixing up as precursor to iio-backend proposal which is under review for 6.9) * Fix reset gpio handling to match expected polarity. * Always handle error codes from spi_writes. * Add a driver instance local mutex to avoid some races. * Fix scale setting to align with available scale values. * Split array of chip_info structures up into named individual elements. * Convert to regmap. honeywell,mprls0025pa * Drop now unnecessary type references in DT binding for properties in pascals. invensense,mpu6050 * Don't eat a potentially useful return value from regmap_bulk_write() invensense,icm42600 * Use max macro to improve code readability and save a few lines. liteon,ltrf216a * Improve prevision of light intensity. microchip,mcp3911 * Use cleanup.h magic. qcom,spmi* * Fix wrong descriptions of SPMI reg fields in bindings.
