[PATCH 1/1] lib/kfifo-test.c: add tests for the kfifo structure

Add KUnit tests for the kfifo data structure. They test the vast majority of macros defined in the kfifo header (include/linux/kfifo.h). These are inspired by the existing tests for the 'list' doubly linked in lib/list-test.c [1]. [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linu

[PATCH 0/1] Add KUnit tests for kfifo

From: diegodvv Hi all, This is part of a hackathon organized by LKCAMP[1], focused on writing tests using KUnit. We reached out a while ago asking for advice on what would be a useful contribution[2] and ended up choosing data structures that did not yet have tests. This patch adds tests for t

[PATCH 1/1] lib/llist_kunit.c: add KUnit tests for llist

Add KUnit tests for the llist data structure. They test the vast majority of methods and macros defined in include/linux/llist.h. These are inspired by the existing tests for the 'list' doubly linked in lib/list-test.c [1]. Each test case (llist_test_x) tests the behaviour of the llist function/ma

[PATCH v4 2/2] selftests/bpf: integrate test_xdp_veth into test_progs

test_xdp_veth.sh tests that XDP return codes work as expected, by bringing up multiple veth pairs isolated in different namespaces, attaching specific xdp programs to each interface, and ensuring that the whole chain allows to ping one end interface from the first one. The test runs well but is cur

[PATCH v4 1/2] selftests/bpf: update xdp_redirect_map prog sections for libbpf

xdp_redirect_map.c is a bpf program used by test_xdp_veth.sh, which is not handled by the generic test runner (test_progs). To allow converting this test to test_progs, the corresponding program must be updated to allow handling it through skeletons generated by bpftool and libbpf. Update programs

[PATCH v4 0/2] selftests/bpf: convert test_xdp_veth to test_progs framework

Hello everyone, this small series is a first step in a larger effort aiming to help improve eBPF selftests and the testing coverage in CI. It focuses for now on test_xdp_veth.sh, a small test which is not integrated yet in test_progs. The series is mostly about a rewrite of test_xdp_veth.sh to mak

[PATCH bpf-next v1 1/2] selftests/bpf: Add missing system defines for mips

Update get_sys_includes in Makefile with missing MIPS-related definitions to fix many, many compilation errors building selftests/bpf. The following added defines drive conditional logic in system headers for word-size and endianness selection: MIPSEL, MIPSEB _MIPS_SZPTR _MIPS_SZLONG _MIPS

[PATCH bpf-next v1 0/2] selftests/bpf: Add support for MIPS systems

Hello, This series includes two fixes to support builds targeting MIPS systems. The patches have been tested both with the kernel-patches/bpf CI and locally using mips64el-gcc/musl-libc and QEMU with an OpenWrt rootfs. Patch 1 adds support for MIPS system includes when compiling BPF. Patch 2 fixe

[PATCH bpf-next v1 2/2] selftests/bpf: Fix error linking uprobe_multi on mips

Linking uprobe_multi.c on mips64el fails due to relocation overflows, when the GOT entries required exceeds the default maximum. Add a specific CFLAGS (-mxgot) for uprobe_multi.c on MIPS that allows using a larger GOT and avoids errors such as: /tmp/ccBTNQzv.o: in function `bench': uprobe_mult
