[PATCH v3] selftests/input: Introduce basic tests for evdev ioctls

by Enric Balletbo i Serra

This provides a basic infrastructure for the creation of tests for the evdev interface. Most of this code is adapted from the libevdev wrapper library. While most of evdev ioctls are covered and tested using libevdev tests there are some evdev ioctls that aren't because are not supported (and will not be supported) by libevdev [1]. So, adding, at least those tests, would make sense. The test creates an uinput device (and an evdev device) so you can call the wanted ioctl from userspace. So, to run those tests you need to have support for uinput and evdev as well. [1] For example, libevdev doesn't support setting EV_REP because it's inherently racy - one libevdev context to set those values via the ioctl would cause all other libevdev contexts on the same device to be out of sync.

[PATCH 0/4] selftests/nolibc: fix up and improve test report

by Zhangjin Wu

Hi, Willy Thanks very much for your merge of the v3 generic part1 of rv32, just tested your latest 20230604-nolibc-rv32+stkp6 branch, everything work well except a trivial test report regression on the 'run' target. Besides the fixup, a standalone test-report target added to share them among run, run-user and re-run and allow independent test report check via direct 'make test-report'.

[PATCH v4 1/3] docs: sound: add 'pcmtest' driver documentation

by Ivan Orlov

Add documentation for the new Virtual PCM Test Driver. It covers all possible usage cases: errors and delay injections, random and pattern-based data generation, playback and ioctl redefinition functionalities testing. We have a lot of different virtual media drivers, which can be used for testing of the userspace applications and media subsystem middle layer. However, all of them are aimed at testing the video functionality and simulating the video devices. For audio devices we have only snd-dummy module, which is good in simulating the correct behavior of an ALSA device. I decided to write a tool, which would help to test the userspace ALSA programs (and the PCM middle layer as well) under unusual circumstances to figure out how they would behave. So I came up with this Virtual PCM Test Driver. This new Virtual PCM Test Driver has several features which can be useful during the userspace ALSA applications testing/fuzzing, or testing/fuzzing of the PCM middle layer. Not all of them can be implemented using the existing virtual drivers (like dummy or loopback). Here is what can this driver do: - Simulate both capture and playback processes - Check the playback stream for containing the looped pattern - Generate random or pattern-based capture data - Inject delays into the playback and capturing processes - Inject errors during the PCM callbacks Also, this driver can check the playback stream for containing the predefined pattern, which is used in the corresponding selftest to check the PCM middle layer data transferring functionality. Additionally, this driver redefines the default RESET ioctl, and the selftest covers this PCM API functionality as well. The driver supports both interleaved and non-interleaved access modes, and have separate pattern buffers for each channel. The driver supports up to 4 channels and up to 8 substreams. Signed-off-by: Ivan Orlov <ivan.orlov0322(a)gmail.com> --- V1 -> V2: - Rename the driver from from 'valsa' to 'pcmtest'. - Implement support for interleaved and non-interleaved access modes - Add support for 8 substreams and 4 channels - Extend supported formats - Extend and rewrite in C the selftest for the driver V2 -> V3: - Add separate pattern buffers for each channel - Speed up the capture data generation when using interleaved access mode - Extend the corresponding selftest to cover the multiple channels capturing and playback functionalities when using interleaved access mode. - Fix documentation issues V3 -> V4: - Fix issue in the selftest: there was a typo in the fscanf argument.

Let's look at the second mode. + +First of all, you may want to specify the pattern for data generation. You can do it +by writing the pattern to the debugfs file. There are pattern buffer debugfs entries +for each channel, as well as entries which contain the pattern buffer length. + + * /sys/kernel/debug/pcmtest/fill_pattern[0-3] + * /sys/kernel/debug/pcmtest/fill_pattern[0-3]_len + +To set the pattern for the channel 0 you can execute the following command: + +.. code-block:: bash + + echo -n mycoolpattern > /sys/kernel/debug/pcmtest/fill_pattern0 + +Then, after every capture action performed on the 'pcmtest' device the buffer for the +channel 0 will contain 'mycoolpatternmycoolpatternmycoolpatternmy...'. + +The pattern itself can be up to 4096 bytes long. + +Delay injection +--------------- + +The driver has 'inject_delay' parameter, which has very self-descriptive name and +can be used for time delay/speedup simulations. The parameter has integer type, and +it means the delay added between module's internal timer ticks. + +If the 'inject_delay' value is positive, the buffer will be filled slower, if it is +negative - faster. You can try it yourself by starting a recording in any +audiorecording application (like Audacity) and selecting the 'pcmtest' device as a +source. + +This parameter can be also used for generating a huge amount of sound data in a very +short period of time (with the negative 'inject_delay' value). + +Errors injection +---------------- + +This module can be used for injecting errors into the PCM communication process. This +action can help you to figure out how the userspace ALSA program behaves under unusual +circumstances. + +For example, you can make all 'hw_params' PCM callback calls return EBUSY error by +writing '1' to the 'inject_hwpars_err' module parameter: + +.. code-block:: bash + + echo 1 > /sys/module/snd_pcmtest/parameters/inject_hwpars_err + +Errors can be injected into the following PCM callbacks: + + * hw_params (EBUSY) + * prepare (EINVAL) + * trigger (EINVAL) + +Playback test +------------- + +This driver can be also used for the playback functionality testing - every time you +write the playback data to the 'pcmtest' PCM device and close it, the driver checks the +buffer for containing the looped pattern (which is specified in the fill_pattern +debugfs file for each channel). If the playback buffer content represents the looped +pattern, 'pc_test' debugfs entry is set into '1'. Otherwise, the driver sets it to '0'. + +ioctl redefinition test +----------------------- + +The driver redefines the 'reset' ioctl, which is default for all PCM devices. To test +this functionality, we can trigger the reset ioctl and check the 'ioctl_test' debugfs +entry: + +.. code-block:: bash + + cat /sys/kernel/debug/pcmtest/ioctl_test + +If the ioctl is triggered successfully, this file will contain '1', and '0' otherwise. -- 2.34.1

[PATCH v3 0/3] nolibc: add part2 of support for rv32

by Zhangjin Wu

Hi, Willy This is the v3 part2 of support for rv32, differs from the v2 part2 [1], we only fix up compile issues in this patchset. With the v3 generic part1 [2] and this patchset, we can compile nolibc for rv32 now. This is based on the idea of suggestions from Arnd [3], instead of '#error' on the unsupported syscall on a target platform, a 'return -ENOSYS' allow us to compile it at first and then allow we fix up the test failures reported by nolibc-test one by one. The first two patches fix up all of the compile failures with '-ENOSYS' (and '#ifdef' if required): tools/nolibc: fix up #error compile failures with -ENOSYS tools/nolibc: fix up undeclared syscall macros with #ifdef and -ENOSYS The last one enables rv32 compile support: selftests/nolibc: riscv: customize makefile for rv32 The above compile support patch here is only for test currently, as Thomas suggested, for a full rv32 support, it should wait for the left parts. Welcome your feedbacks, will wait for enough discussion on this patchset and then send the left parts one by one to fix up the test failures about waitid, llseek and time64 syscalls: ppoll_time64, clock_gettime64, pselect6_time64. So, I do recommend to apply this patchset, it allows us to send the left parts independently, otherwise, all of them should be sent out for review together. with this patchset, the rv32 users may be able to use nolibc although some syscalls still missing :-) Or at least we apply the first two, so, I can manually cherry-pick the compile support patch to do my local test, and the other platform developer may also benefit from them. I'm cleaning up the left parts, but still require some time, I plan to split them to such parts: * part3: waitid, prepared, will send out later * part4: llseek, prepared, will send out later * part5: time64 syscalls, ppoll_time64 ok, will finish them next week (It is a little hard to split them) Best regards, Zhangjin --- [1]: https://lore.kernel.org/linux-riscv/cover.1685387484.git.falcon@tinylab.org… [2]: https://lore.kernel.org/linux-riscv/cover.1685777982.git.falcon@tinylab.org… [3]: https://lore.kernel.org/linux-riscv/5e7d2adf-e96f-41ca-a4c6-5c87a25d4c9c@ap… Zhangjin Wu (3): tools/nolibc: fix up #error compile failures with -ENOSYS tools/nolibc: fix up undeclared syscall macros with #ifdef and -ENOSYS selftests/nolibc: riscv: customize makefile for rv32 tools/include/nolibc/sys.h | 38 ++++++++++++++++--------- tools/testing/selftests/nolibc/Makefile | 11 +++++-- 2 files changed, 34 insertions(+), 15 deletions(-) -- 2.25.1

[PATCH v4 0/3] nolibc: add part2 of support for rv32

by Zhangjin Wu

Hi, Willy This is the v4 part2 of support for rv32 (v3 [1]), it applied the suggestions from Thomas, Arnd [2] and you [3]. now, the rv32 compile support almost aligned with x86 except the extra KARCH to make kernel happy, thanks very much for your nice review! Since the 'override' method mentioned in [4] split the whole Makefile context to two parts, it may make the code not that easy to maintain, so, this patchset goes back to the KARCH (suggested from Willy, before, I used something like _ARCH) passing method, as suggested by Willy, we also aligned the KARCH assignment with the other variables. Changes from v3 -> v4: * No new changes in the first two except a new Reviewed-by line from Arnd * selftests/nolibc: riscv: customize makefile for rv32 Do it like the other architectures, especially like x86. The difference from x86 is, the top-level kernel Makefile doesn't accept riscv32 and riscv64, it only accept riscv, to make kernel happy, a KARCH variable is added for riscv32 and riscv64, and then passed to kernel with ARCH=$(KARCH). Since tools/include/nolibc/Makefile shares arch-riscv.h between riscv32 and riscv64 and there is a headers_standalone target who called kernel headers and headers_install, so, pass ARCH=$(KARCH) to it too. Did compile test for aarch64, rv32 and rv64, include run-user and run.

[PATCH 0/8] Remove child from struct ctl_table

by Joel Granados

Resending as the first set got mangled with smtp error. This is part of the effort to remove the empty element of the ctl_table structures (used to calculate size) and replace it with an ARRAY_SIZE call. By replacing the child element in struct ctl_table with a flags element we make sure that there are no forward recursions on child nodes and therefore set ourselves up for just using an ARRAY_SIZE. We also added some self tests to make sure that we do not break anything. Patchset is separated in 4: parport fixes, selftests fixes, selftests additions and replacement of child element. Tested everything with sysctl self tests and everything seems "ok". 1. parport fixes: @mcgrof: this is related to my previous series and it plugs a sysct table leak in the parport driver. Please tell me if you want me to repost the parport series with this one stiched in. 2. Selftests fixes: Remove the prefixed zeros when passing a awk field to the awk print command because it was causing $0009 to be interpreted as $0. Replaced continue with return in sysctl.sh(test_case) so the test actually gets skipped. The skip decision is now in sysctl.sh(skip_test). 3. Selftest additions: New test to confirm that unregister actually removes targets. New test to confirm that permanently empty targets are indeed created and that no other targets can be created "on top". 4. Replaced the child pointer in struct ctl_table with a u8 flag. The flag is used to differentiate between permanently empty targets and non-empty ones.

[PATCH bpf v3 0/2] Fix BPF verifier bypass on scalar spill

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> See the details in the commit message (TL/DR: under CAP_BPF, the verifier can be fooled to think that a scalar is zero while in fact it's your predefined number.) v1 and v2 were sent off-list. v2 changes: Added more tests, migrated them to inline asm, started using bpf_get_prandom_u32, switched to a more bulletproof dead branch check and modified the failing spill test scenarios so that an unauthorized access attempt is performed in both branches. v3 changes: Dropped an improvement not necessary for the fix, changed the Fixes tag.
