kernel/tools/testing/selftests/bpf/progs/file_reader.c, branch linux-rolling-stableHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-rolling-stable2025-11-15T01:45:43Zselftests/bpf: Align kfuncs renamed in bpf tree2025-11-15T01:45:43ZMykyta Yatsenkoyatsenko@meta.com2025-11-05T13:21:05Zurn:sha1:a4d31f451d5be2a65cfe8459808948071e9b54a0
bpf_task_work_schedule_resume() and bpf_task_work_schedule_signal() have
been renamed in bpf tree to bpf_task_work_schedule_resume_impl() and
bpf_task_work_schedule_signal_impl() accordingly.
There are few uses of these kfuncs in selftests that are not in bpf
tree, so that when we port [1] into bpf-next, those BPF programs will
not compile.
This patch aligns those remaining callsites with the kfunc renaming.
It should go on top of [1] when applying on bpf-next.

selftests/bpf: Fix intermittent failures in file_reader test2025-10-30T01:15:30ZMykyta Yatsenkoyatsenko@meta.com2025-10-29T19:59:07Zurn:sha1:5913e936f6d5d348e33190885131c4f4eaa4bc4b
file_reader/on_open_expect_fault intermittently fails when test_progs
runs tests in parallel, because it expects a page fault on first read.
Another file_reader test running concurrently may have already pulled
the same pages into the page cache, eliminating the fault and causing a
spurious failure.
Make file_reader/on_open_expect_fault read from a file region that does
not overlap with other file_reader tests, so the initial access still
faults even under parallel execution.

selftests/bpf: add file dynptr tests2025-10-27T16:56:27ZMykyta Yatsenkoyatsenko@meta.com2025-10-26T20:38:53Zurn:sha1:784cdf931543805120aed1e1c43df8e6fa436a55
Introducing selftests for validating file-backed dynptr works as
expected.
* validate implementation supports dynptr slice and read operations
* validate destructors should be paired with initializers
* validate sleepable progs can page in.
