[PATCH net-next] selftests/bpf: Fix bpf selftest build warning

by Saket Kumar Bhaskar

On linux-next, build for bpf selftest displays a warning: Warning: Kernel ABI header at 'tools/include/uapi/linux/if_xdp.h' differs from latest version at 'include/uapi/linux/if_xdp.h'. Commit 8066e388be48 ("net: add UAPI to the header guard in various network headers") changed the header guard from _LINUX_IF_XDP_H to _UAPI_LINUX_IF_XDP_H in include/uapi/linux/if_xdp.h. To resolve the warning, update tools/include/uapi/linux/if_xdp.h to align with the changes in include/uapi/linux/if_xdp.h Fixes: 8066e388be48 ("net: add UAPI to the header guard in various network headers") Reported-by: Venkat Rao Bagalkote <venkat88(a)linux.ibm.com> Closes: https://lore.kernel.org/all/c2bc466d-dff2-4d0d-a797-9af7f676c065@linux.ibm.… Tested-by: Venkat Rao Bagalkote <venkat88(a)linux.ibm.com> Signed-off-by: Saket Kumar Bhaskar <skb99(a)linux.ibm.com> --- tools/include/uapi/linux/if_xdp.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/tools/include/uapi/linux/if_xdp.h b/tools/include/uapi/linux/if_xdp.h index 42869770776e..44f2bb93e7e6 100644 --- a/tools/include/uapi/linux/if_xdp.h +++ b/tools/include/uapi/linux/if_xdp.h @@ -7,8 +7,8 @@ * Magnus Karlsson <magnus.karlsson(a)intel.com> */ -#ifndef _LINUX_IF_XDP_H -#define _LINUX_IF_XDP_H +#ifndef _UAPI_LINUX_IF_XDP_H +#define _UAPI_LINUX_IF_XDP_H #include <linux/types.h> @@ -180,4 +180,4 @@ struct xdp_desc { /* TX packet carries valid metadata. */ #define XDP_TX_METADATA (1 << 1) -#endif /* _LINUX_IF_XDP_H */ +#endif /* _UAPI_LINUX_IF_XDP_H */ -- 2.43.5

[PATCH 0/7] Rust KUnit `#[test]` support improvements

by Miguel Ojeda

Improvements that build on top of the very basic `#[test]` support merged in v6.15. They are fairly minimal changes, but they allow us to map `assert*!`s back to KUnit, plus to add support for test functions that return `Result`s. In essence, they get our `#[test]`s essentially on par with the documentation tests. I also took the chance to convert some host `#[test]`s we had to KUnit in order to showcase the feature. Finally, I added documentation that was lacking from the original submission. I hope this helps. Miguel Ojeda (7): rust: kunit: support KUnit-mapped `assert!` macros in `#[test]`s rust: kunit: support checked `-> Result`s in KUnit `#[test]`s rust: add `kunit_tests` to the prelude rust: str: convert `rusttest` tests into KUnit rust: str: take advantage of the `-> Result` support in KUnit `#[test]`'s Documentation: rust: rename `#[test]`s to "`rusttest` host tests" Documentation: rust: testing: add docs on the new KUnit `#[test]` tests Documentation/rust/testing.rst | 80 ++++++++++++++++++++++++++++++++-- init/Kconfig | 3 ++ rust/Makefile | 3 +- rust/kernel/kunit.rs | 29 ++++++++++-- rust/kernel/prelude.rs | 2 +- rust/kernel/str.rs | 76 ++++++++++++++------------------ rust/macros/helpers.rs | 16 +++++++ rust/macros/kunit.rs | 31 ++++++++++++- rust/macros/lib.rs | 6 ++- 9 files changed, 191 insertions(+), 55 deletions(-) base-commit: b4432656b36e5cc1d50a1f2dc15357543add530e -- 2.49.0

In previous versions, this value was fixed to 2, so the step threshold was applied to mark packets in the L queue only when the queue length of the L queue was greater than or equal to 2 packets. This will cause larger queuing delays for L4S traffic at low rates (<20Mbps). So we parameterize it and change the default value to 0.

[PATCH net-next 1/3] net: devmem: support single IOV with sendmsg

by Stanislav Fomichev

sendmsg() with a single iov becomes ITER_UBUF, sendmsg() with multiple iovs becomes ITER_IOVEC. iter_iov_len does not return correct value for UBUF, so teach to treat UBUF differently.

[PATCHv2 net-next] selftests: net: move wait_local_port_listen to lib.sh

by Hangbin Liu

The function wait_local_port_listen() is the only function defined in net_helper.sh. Since some tests source both lib.sh and net_helper.sh, we can simplify the setup by moving wait_local_port_listen() to lib.sh. With this change, net_helper.sh becomes redundant and can be removed.

[PATCH net-next v8] selftests/vsock: add initial vmtest.sh for vsock

by Bobby Eshleman

This commit introduces a new vmtest.sh runner for vsock. It uses virtme-ng/qemu to run tests in a VM. The tests validate G2H, H2G, and loopback. The testing tools from tools/testing/vsock/ are reused. Currently, only vsock_test is used. VMCI and hyperv support is included in the config file to be built with the -b option, though not used in the tests. Only tested on x86. To run: $ make -C tools/testing/selftests TARGETS=vsock $ tools/testing/selftests/vsock/vmtest.sh or $ make -C tools/testing/selftests TARGETS=vsock run_tests Example runs (after make -C tools/testing/selftests TARGETS=vsock): $ ./tools/testing/selftests/vsock/vmtest.sh 1..3 ok 0 vm_server_host_client ok 1 vm_client_host_server ok 2 vm_loopback SUMMARY: PASS=3 SKIP=0 FAIL=0 Log: /tmp/vsock_vmtest_m7DI.log $ ./tools/testing/selftests/vsock/vmtest.sh vm_loopback 1..1 ok 0 vm_loopback SUMMARY: PASS=1 SKIP=0 FAIL=0 Log: /tmp/vsock_vmtest_a1IO.log $ mkdir -p ~/scratch $ make -C tools/testing/selftests install TARGETS=vsock INSTALL_PATH=~/scratch [... omitted ...] $ cd ~/scratch $ ./run_kselftest.sh TAP version 13 1..1 # timeout set to 300 # selftests: vsock: vmtest.sh # 1..3 # ok 0 vm_server_host_client # ok 1 vm_client_host_server # ok 2 vm_loopback # SUMMARY: PASS=3 SKIP=0 FAIL=0 # Log: /tmp/vsock_vmtest_svEl.log ok 1 selftests: vsock: vmtest.sh Future work can include vsock_diag_test. Because vsock requires a VM to test anything other than loopback, this patch adds vmtest.sh as a kselftest itself. This is different than other systems that have a "vmtest.sh", where it is used as a utility script to spin up a VM to run the selftests as a guest (but isn't hooked into kselftest).
