If HID_SUPPORT is not selected, BT_HIDP should not be available, simply because we disallowed the HID bus entirely. Add a new depends and actually revert this file back to where it was 10 years ago before it was changed by commit 1f41a6a9 ("HID: Fix the generic Kconfig options"). Fixes: 25621bcc ("HID: Kconfig: split HID support and hid-core compilation") Reported-by:

dispatch_hid_bpf_device_event() is supposed to return either an error, or a valid pointer to memory containing the data. Returning NULL simply makes a segfault when CONFIG_HID_BPF is not set for any processed event. Fixes: 658ee5a6 ("HID: bpf: allocate data memory for device_event BPF program") Signed-off-by:

Benjamin Tissoires authored
Everything should be available in the selftest part of the tree, but providing an example without uhid and hidraw will be more easy to follow for users. This example will probably ever only work on the Etekcity Scroll 6E because we need to adapt the various raw values to the actual device. On that device, the X and Y axis will be swapped and inverted, and on any other device, chances are high that the device will not work until Ctrl-C is hit. The Makefiles are taken from samples/bpf to not reinvent the wheel and to force using in-kernel libbpf and bpftool. Signed-off-by:

Simple report descriptor override in HID: replace part of the report descriptor from a static definition in the bpf kernel program. Note that this test should be run last because we disconnect/reconnect the device, meaning that it changes the overall uhid device. Signed-off-by:

Add a new tracepoint hid_bpf_rdesc_fixup() so we can trigger a report descriptor fixup in the bpf world. Whenever the program gets attached/detached, the device is reconnected meaning that userspace will see it disappearing and reappearing with the new report descriptor. Reviewed-by:

Add tests for the newly implemented function. We test here only the GET_REPORT part because the other calls are pure HID protocol and won't infer the result of the test of the bpf hook. Signed-off-by:

Benjamin Tissoires authored
This function can not be called under IRQ, thus it is only available while in SEC("syscall"). For consistency, this function requires a HID-BPF context to work with, and so we also provide a helper to create one based on the HID unique ID. Reviewed-by: -

Use a different report with a bigger size and ensures we are doing things properly. Signed-off-by:
-
Benjamin Tissoires authored
We need to also be able to change the size of the report. Reducing it is easy, because we already have the incoming buffer that is big enough, but extending it is harder. Pre-allocate a buffer that is big enough to handle all reports of the device, and use that as the primary buffer for BPF programs. To be able to change the size of the buffer, we change the device_event API and request it to return the size of the buffer. Reviewed-by:

Kind of a hack, but works for now: Instead of listening for any close of eBPF program, we now decrement the refcount when we insert it in our internal map of fd progs. This is safe to do because: - we listen to any call of destructor of programs - when a program is being destroyed, we disable it by removing it from any RCU list used by any HID device (so it will never be called) - we then trigger a job to cleanup the prog fd map, but we overwrite the removal of the elements to not do anything on the programs, just remove the allocated space This is better than previously because we can remove the map of known programs and their usage count. We now rely on the refcount of bpf, which has greater chances of being accurate. Signed-off-by:

Benjamin Tissoires authored
The tests are pretty basic: - create a virtual uhid device that no userspace will like (to not mess up the running system) - attach a BPF prog to it - open the matching hidraw node - inject one event and check: * that the BPF program can do something on the event stream * can modify the event stream - add another test where we attach/detach BPF programs to see if we get errors Note: the Makefile is extracted from selftests/bpf so we can rebuild the libbpf and bpftool components from the current kernel tree without relying on system installed components.

Declare an entry point that can use fmod_ret BPF programs, and also an API to access and change the incoming data. A simpler implementation would consist in just calling hid_bpf_device_event() for any incoming event and let users deal with the fact that they will be called for any event of any device. The goal of HID-BPF is to partially replace drivers, so this situation can be problematic because we might have programs which will step on each other toes. For that, we add a new API hid_bpf_attach_prog() that can be called from a syscall and we manually deal with a jump table in hid-bpf. Whenever we add a program to the jump table (in other words, when we attach a program to a HID device), we keep the number of time we added this program in the jump table so we can release it whenever there are no other users. HID devices have an RCU protected list of available programs in the jump table, and those programs are called one after the other thanks to bpf_tail_call(). To achieve the detection of users losing their fds on the programs we attached, we add 2 tracing facilities on bpf_prog_release() (for when a fd is closed) and bpf_free_inode() (for when a pinned program gets unpinned).

Currently, we step into drivers/hid/ based on the value of CONFIG_HID. However, that value is a tristate, meaning that it can be a module. As per the documentation, if we jump into the subdirectory by following an obj-m, we can not compile anything inside that subdirectory in vmlinux. It is considered as a bug. To make things more friendly to HID-BPF, split HID (the HID core parameter) from HID_SUPPORT (do we want any kind of HID support in the system?), and make this new config a boolean. Reviewed-by:

When the non-contiguous page allocation for SG buffer allocation fails, the memalloc helper tries to fall back to the old page allocation methods. This would, however, result in the bogus page addresses when IOMMU is enabled. Usually in such a case, the fallback allocation should fail as well, but occasionally it succeeds and hitting a bad access. The fallback was thought for non-IOMMU case, and as the error from dma_alloc_noncontiguous() with IOMMU essentially implies a fatal memory allocation error, we should return the error straightforwardly without fallback. This avoids the corner case like the above. The patch also renames the local variable "dma_ops" with snd_ prefix for avoiding the name conflict.
