[PATCH RFC] Makefile: Export absolute srctree path for out-of-tree builds

by Li Zhijian

Fixes an issue where out-of-tree kselftest builds fail when building the BPF and bpftools components. The failure occurs because the top-level Makefile passes a relative srctree path ('..') to its sub-Makefiles, which leads to errors in locating necessary files. For example, the following error is encountered: ``` $ make V=1 O=$build/ TARGETS=hid kselftest-all ... make -C ../tools/testing/selftests all make[4]: Entering directory '/path/to/linux/tools/testing/selftests/hid' make -C /path/to/linux/tools/testing/selftests/../../../tools/lib/bpf OUTPUT=/path/to/linux/O/kselftest/hid/tools/build/libbpf/ \ EXTRA_CFLAGS='-g -O0' \ DESTDIR=/path/to/linux/O/kselftest/hid/tools prefix= all install_headers make[5]: Entering directory '/path/to/linux/tools/lib/bpf' ... make[5]: Entering directory '/path/to/linux/tools/bpf/bpftool' Makefile:127: ../tools/build/Makefile.feature: No such file or directory make[5]: *** No rule to make target '../tools/build/Makefile.feature'. Stop. ``` To resolve this, the srctree is exported as an absolute path (abs_srctree) when performing an out-of-tree build. This ensures that all sub-Makefiles have the correct path to the source tree, preventing directory resolution errors. Signed-off-by: Li Zhijian <lizhijian(a)fujitsu.com> --- Request for Additional Testing We welcome all contributors and CI systems to test this change thoroughly. In theory, this change should not affect in-tree builds. However, to ensure stability and compatibility, we encourage testing across different configurations.

[PATCH 0/2] fix reading ESP during coredump

by Nam Cao

Hi, In /proc/PID/stat, there is the kstkesp field which is the stack pointer of a thread. While the thread is active, this field reads zero. But during a coredump, it should have a valid value. However, at the moment, kstkesp is zero even during coredump. The first commit fixes this problem, and the second commit adds a selftest to detect if this problem appears again in the future.

[PATCH bpf] selftests/bpf: add XDP_UMEM_TX_METADATA_LEN flag to umem_config

by Wei Fang

The Tx metadata test has been broken since the commit d5e726d9143c ("xsk: Require XDP_UMEM_TX_METADATA_LEN to actuate tx_metadata_len"). Because this change requires XDP_UMEM_TX_METADATA_LEN flag to be set, otherwise xsk_buff_pool::tx_metadata_len will be initialized to 0, which means that the driver cannot get Tx metadata and cannot execute AF_XDP Tx metadata hooks.

[PATCH v3 0/3] drivers: base: Don't match device with NULL of_node/fwnode/etc + tests

by Brian Norris

This series: 1. makes the behavior of_find_device_by_node(), bus_find_device_by_of_node(), bus_find_device_by_fwnode(), etc., more consistent when provided with a NULL node/handle; 2. adds kunit tests to validate the new NULL-argument behavior; and 3. makes some related improvements and refactoring for the drivers/base/ kunit tests. This series aims to prevent problems like the ones resolved in commit 5c8418cf4025 ("PCI/pwrctrl: Unregister platform device only if one actually exists"). Changes in v3: * Fix potential leak in test error case Changes in v2: * CC LKML (oops!) * Keep "devm" and "match" tests in separate suites Brian Norris (3): drivers: base: Don't match devices with NULL of_node/fwnode/etc drivers: base: test: Enable device model tests with KUNIT_ALL_TESTS drivers: base: test: Add ...find_device_by...(...

[PATCH AUTOSEL 6.12 29/29] bpf: consider that tail calls invalidate packet pointers

by Sasha Levin

From: Eduard Zingerman <eddyz87(a)gmail.com> [ Upstream commit 1a4607ffba35bf2a630aab299e34dd3f6e658d70 ] Tail-called programs could execute any of the helpers that invalidate packet pointers. Hence, conservatively assume that each tail call invalidates packet pointers. Making the change in bpf_helper_changes_pkt_data() automatically makes use of check_cfg() logic that computes 'changes_pkt_data' effect for global sub-programs, such that the following program could be rejected: int tail_call(struct __sk_buff *sk) { bpf_tail_call_static(sk, &jmp_table, 0); return 0; } SEC("tc") int not_safe(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; ... make p valid ... tail_call(sk); *p = 42; /* this is unsafe */ ... } The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function that can invalidate packet pointers. Otherwise, it can't be freplaced with tailcall_freplace.c:entry_freplace() that does a tail call.

[PATCH v6 0/2] kselftest: tmpfs: Add ksft macros and skip if no root

by Shivam Chaudhary

This version 5 patch series replace direct error handling methods with ksft macros, which provide better reporting.Currently, when the tmpfs test runs, it does not display any output if it passes,and if it fails (particularly when not run as root),it simply exits without any warning or message. This series of patch adds: 1. Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test outputs more effectively. 2. skip if not run as root. 3. Replace direct error handling with 'ksft_test_result_*', macros for better reporting. v5->v6: - Skip if not run as root. v5 v1: https://lore.kernel.org/all/20241112143056.565122-2-cvam0000@gmail.com/ v5 v2: https://lore.kernel.org/all/20241112143056.565122-3-cvam0000@gmail.com/ v4->v5: - Remove unnecessary pass messages. - Remove unnecessary use of KSFT_SKIP. - Add appropriate use of ksft_exit_fail_msg. v4 v1: https://lore.kernel.org/all/8db9feab-0600-440b-b4b2-042695a100b5@linuxfound… v4 v2: https://lore.kernel.org/all/63d5e3bb-9817-4a34-98fe-823a9cac7c16@linuxfound… v3->v4: - Start a patchset - Split patch into smaller patches to make it easy to review.

[PATCH for-next] selftests/alsa: Fix circular dependency involving global-timer

by Li Zhijian

The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular dependency on the global-timer target due to its inclusion in $(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency warning during the build process. To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change ensures that libatest.so is built before any other targets that require it, without creating a circular dependency. This fix addresses the following warning: make[4]: Entering directory 'tools/testing/selftests/alsa' make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped. make[4]: Nothing to be done for 'all'. make[4]: Leaving directory 'tools/testing/selftests/alsa' Cc: Mark Brown <broonie(a)kernel.org> Cc: Jaroslav Kysela <perex(a)perex.cz> Cc: Takashi Iwai <tiwai(a)suse.com> Cc: Shuah Khan <shuah(a)kernel.org> Signed-off-by: Li Zhijian <lizhijian(a)fujitsu.com> --- Cc: linux-sound(a)vger.kernel.org Cc: linux-kselftest(a)vger.kernel.org Cc: linux-kernel(a)vger.kernel.org --- tools/testing/selftests/alsa/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/alsa/Makefile b/tools/testing/selftests/alsa/Makefile index 944279160fed..8dab90ad22bb 100644 --- a/tools/testing/selftests/alsa/Makefile +++ b/tools/testing/selftests/alsa/Makefile @@ -27,5 +27,5 @@ include ../lib.mk $(OUTPUT)/libatest.so: conf.c alsa-local.h $(CC) $(CFLAGS) -shared -fPIC $< $(LDLIBS) -o $@ -$(OUTPUT)/%: %.c $(TEST_GEN_PROGS_EXTENDED) alsa-local.h +$(OUTPUT)/%: %.c $(OUTPUT)/libatest.so alsa-local.h $(CC) $(CFLAGS) $< $(LDLIBS) -latest -o $@ -- 2.44.0
