2024-06-27selftests/hid: add another test for injecting an event from an event hookBenjamin Tissoires
Similar to test_multiply_events_wq: we receive one event and inject a new one. But given that this time we are already in the event hook, we can use hid_bpf_try_input_report() directly as this function will not sleep. Note that the injected event gets processed before the original one this way.

2024-06-27selftests/hid: add wq test for hid_bpf_input_report()Benjamin Tissoires
Now that bpf_wq is available, we can write a test with it. Having hid_bpf_input_report() waiting for the device means that we can directly call it, and we get that event when the device is ready.

2024-06-25cxl/region: check interleave capabilityYao Xingtao
Since interleave capability is not verified, if the interleave capability of a target does not match the region need, committing decoder should have failed at the device end. In order to checkout this error as quickly as possible, driver needs to check the interleave capability of target during attaching it to region. Per CXL specification r3.1(8.2.4.20.1 CXL HDM Decoder Capability Register), bits 11 and 12 indicate the capability to establish interleaving in 3, 6, 12 and 16 ways. If these bits are not set, the target cannot be attached to a region utilizing such interleave ways. Additionally, bits 8 and 9 represent the capability of the bits used for interleaving in the address, Linux tracks this in the cxl_port interleave_mask. Per CXL specification r3.1(8.2.4.20.13 Decoder Protection): eIW means encoded Interleave Ways. eIG means encoded Interleave Granularity. in HPA: if eIW is 0 or 8 (interleave ways: 1, 3), all the bits of HPA are used, the interleave bits are none, the following check is ignored. if eIW is less than 8 (interleave ways: 2, 4, 8, 16), the interleave bits start at bit position eIG + 8 and end at eIG + eIW + 8 - 1. if eIW is greater than 8 (interleave ways: 6, 12), the interleave bits start at bit position eIG + 8 and end at eIG + eIW - 1. if the interleave mask is insufficient to cover the required interleave bits, the target cannot be attached to the region.

2024-06-25selftests/bpf: add test validating uprobe/uretprobe stack tracesAndrii Nakryiko
Add a set of tests to validate that stack traces captured from or in the presence of active uprobes and uretprobes are valid and complete. For this we use BPF program that are installed either on entry or exit of user function, plus deep-nested USDT. One of target funtions (target_1) is recursive to generate two different entries in the stack trace for the same uprobe/uretprobe, testing potential edge conditions. If there is no fixes, we get something like this for one of the scenarios: caller: 0x758fff - 0x7595ab target_1: 0x758fd5 - 0x758fff target_2: 0x758fca - 0x758fd5 target_3: 0x758fbf - 0x758fca target_4: 0x758fb3 - 0x758fbf ENTRY #0: 0x758fb3 (in target_4) ENTRY #1: 0x758fd3 (in target_2) ENTRY #2: 0x758ffd (in target_1) ENTRY #3: 0x7fffffffe000 ENTRY #4: 0x7fffffffe000 ENTRY #5: 0x6f8f39 ENTRY #6: 0x6fa6f0 ENTRY #7: 0x7f403f229590 Entry #3 and #4 (0x7fffffffe000) are uretprobe trampoline addresses which obscure actual target_1 and another target_1 invocations. Also note that between entry #0 and entry #1 we are missing an entry for target_3. With fixes, we get desired full stack traces: caller: 0x758fff - 0x7595ab target_1: 0x758fd5 - 0x758fff target_2: 0x758fca - 0x758fd5 target_3: 0x758fbf - 0x758fca target_4: 0x758fb3 - 0x758fbf ENTRY #0: 0x758fb7 (in target_4) ENTRY #1: 0x758fc8 (in target_3) ENTRY #2: 0x758fd3 (in target_2) ENTRY #3: 0x758ffd (in target_1) ENTRY #4: 0x758ff3 (in target_1) ENTRY #5: 0x75922c (in caller) ENTRY #6: 0x6f8f39 ENTRY #7: 0x6fa6f0 ENTRY #8: 0x7f986adc4cd0 Now there is a logical and complete sequence of function calls.

2024-06-21selftests/bpf: Add kfunc_call test for simple dtor in bpf_testmodAlan Maguire
add simple kfuncs to create/destroy a context type to bpf_testmod, register them and add a kfunc_call test to use them. This provides test coverage for registration of dtor kfuncs from modules. By transferring the context pointer to a map value as a __kptr we also trigger the map-based dtor cleanup logic, improving test coverage.

2024-06-20selftests/bpf: Drop type from network_helper_optsGeliang Tang
The opts.{type, noconnect} is at least a bit non intuitive or unnecessary. The only use case now is in test_bpf_ip_check_defrag_ok which ends up bypassing most (or at least some) of the connect_to_fd_opts() logic. It's much better that test should have its own connect_to_fd_opts() instead. This patch adds a new "type" parameter for connect_to_fd_opts(), then opts->type and getsockopt(SO_TYPE) can be replaced by "type" parameter in it. In connect_to_fd(), use getsockopt(SO_TYPE) to get "type" value and pass it to connect_to_fd_opts(). In bpf_tcp_ca.c and cgroup_v1v2.c, "SOCK_STREAM" types are passed to connect_to_fd_opts(), and in ip_check_defrag.c, different types "SOCK_RAW" and "SOCK_DGRAM" are passed to it. With these changes, the strcut member "type" of network_helper_opts can be dropped now.

Introduce a new 'of-fullname-regex' property that takes a regular expression and matches against the OF_FULLNAME property. It allows matching controllers that don't have a unique DT address across sibling controllers, and thus dt-mmio can't be used. One particular example of where this is needed is on MT8195 which has multiple USB controllers described by two level deep nodes and using the ranges property: ssusb2: usb@112a1000 { reg = <0 0x112a1000 0 0x2dff>, <0 0x112a3e00 0 0x0100>; ranges = <0 0 0 0x112a0000 0 0x3f00>; xhci2: usb@0 { Signed-off-by: Nícolas F.
