Re: [PATCH 00/31] NT synchronization primitive driver

by Alexey Dobriyan

> drivers/misc/ntsync.c | 1146 ++++++++++++++ Assuming this doesn't go into futex(2) or some other existing code... Can you start putting all of this into top-level "windows" directory? I suspect there will be more Windows stuff in the future. So those who don't care about Windows can turn off just one config option (CONFIG_WINDOWS) and be done with it. Name it "Linux Subsystem for Windows" for 146% better memes.

[PATCH RFC bpf-next v2 00/10] allow HID-BPF to do device IOs

by Benjamin Tissoires

[Still a RFC: there are a lot of FIXMEs in the code, and calling the sleepable timer cb actually crashes.] [Also using bpf-next as the base tree as there will be conflicting changes otherwise] This is crashing, and I have a few questions in the code (look for all of the FIXMEs), so sending this now before I become insane :) For reference, the use cases I have in mind: --- Basically, I need to be able to defer a HID-BPF program for the following reasons (from the aforementioned patch): 1. defer an event: Sometimes we receive an out of proximity event, but the device can not be trusted enough, and we need to ensure that we won't receive another one in the following n milliseconds. So we need to wait those n milliseconds, and eventually re-inject that event in the stack. 2. inject new events in reaction to one given event: We might want to transform one given event into several. This is the case for macro keys where a single key press is supposed to send a sequence of key presses. But this could also be used to patch a faulty behavior, if a device forgets to send a release event. 3. communicate with the device in reaction to one event: We might want to communicate back to the device after a given event. For example a device might send us an event saying that it came back from sleeping state and needs to be re-initialized. Currently we can achieve that by keeping a userspace program around, raise a bpf event, and let that userspace program inject the events and commands. However, we are just keeping that program alive as a daemon for just scheduling commands. There is no logic in it, so it doesn't really justify an actual userspace wakeup. So a kernel workqueue seems simpler to handle. The other part I'm not sure is whether we can say that BPF maps of type queue/stack can be used in sleepable context. I don't see any warning when running the test programs, but that's probably not a guarantee I'm doing the things properly :) Cheers, Benjamin To: Alexei Starovoitov <ast(a)kernel.org> To: Daniel Borkmann <daniel(a)iogearbox.net> To: John Fastabend <john.fastabend(a)gmail.com> To: Andrii Nakryiko <andrii(a)kernel.org> To: Martin KaFai Lau <martin.lau(a)linux.dev> To: Eduard Zingerman <eddyz87(a)gmail.com> To: Song Liu <song(a)kernel.org> To: Yonghong Song <yonghong.song(a)linux.dev> To: KP Singh <kpsingh(a)kernel.org> To: Stanislav Fomichev <sdf(a)google.com> To: Hao Luo <haoluo(a)google.com> To: Jiri Olsa <jolsa(a)kernel.org> To: Jiri Kosina <jikos(a)kernel.org> To: Benjamin Tissoires <benjamin.tissoires(a)redhat.com> To: Jonathan Corbet <corbet(a)lwn.net> To: Shuah Khan <shuah(a)kernel.org> Cc: <bpf(a)vger.kernel.org> Cc: <linux-kernel(a)vger.kernel.org> Cc: <linux-input(a)vger.kernel.org> Cc: <linux-doc(a)vger.kernel.org> Cc: <linux-kselftest(a)vger.kernel.org> Signed-off-by: Benjamin Tissoires <bentiss(a)kernel.org> --- Changes in v2: - make use of bpf_timer (and dropped the custom HID handling) - implemented bpf_timer_set_sleepable_cb as a kfunc - still not implemented global subprogs - no sleepable bpf_timer selftests yet - Link to v1: https://lore.kernel.org/r/20240209-hid-bpf-sleepable-v1-0-4cc895b5adbd@kern… --- Benjamin Tissoires (10): bpf/verifier: introduce in_sleepable() helper bpf/helpers: introduce sleepable timers bpf/verifier: allow more maps in sleepable bpf programs HID: bpf/dispatch: regroup kfuncs definitions HID: bpf: export hid_hw_output_report as a BPF kfunc selftests/hid: Add test for hid_bpf_hw_output_report HID: bpf: allow to inject HID event from BPF selftests/hid: add tests for hid_bpf_input_report HID: bpf: allow to use bpf_timer_set_sleepable_cb() in tracing callbacks. selftests/hid: add test for bpf_timer Documentation/hid/hid-bpf.rst | 2 +- drivers/hid/bpf/hid_bpf_dispatch.c | 232 ++++++++++++++------- drivers/hid/hid-core.c | 2 + include/linux/bpf_verifier.h | 2 + include/linux/hid_bpf.h | 3 + include/uapi/linux/bpf.h | 12 ++ kernel/bpf/helpers.c | 105 +++++++++- kernel/bpf/verifier.c | 91 +++++++- tools/testing/selftests/hid/hid_bpf.c | 195 ++++++++++++++++- tools/testing/selftests/hid/progs/hid.c | 198 ++++++++++++++++++ .../testing/selftests/hid/progs/hid_bpf_helpers.h | 8 + 11 files changed, 756 insertions(+), 94 deletions(-) --- base-commit: 4f7a05917237b006ceae760507b3d15305769ade change-id: 20240205-hid-bpf-sleepable-c01260fd91c4 Best regards, -- Benjamin Tissoires <bentiss(a)kernel.org>

I've added David, Brendan and Rae in Cc. To sum up the problem, your tests are relying on the mock device created to run a kunit test to be the sole DRM device in the system. But if you compile a kernel with the kunit tests enabled and boot that on a real hardware, then that assumption might not be true anymore and things break apart. Is that a fair description? If so, maybe we could detect if it's running under qemu or UML (if that's something we can do in the first place), and then extend kunit_attributes to only run that test if it's in a simulated environment.
