[PATCH net v2 0/3] net: prevent deadlocks and mis-configuration with per-NAPI threaded config

by Jakub Kicinski

Running the test added with a recent fix on a driver with persistent NAPI config leads to a deadlock. The deadlock is fixed by patch 3, patch 2 is I think a more fundamental problem with the way we implemented the config. I hope the fix makes sense, my own thinking is definitely colored by my preference (IOW how the per-queue config RFC was implemented). v2: add missing kdoc v1: https://lore.kernel.org/20250808014952.724762-1-kuba@kernel.org Jakub Kicinski (3): selftests: drv-net: don't assume device has only 2 queues net: update NAPI threaded config even for disabled NAPIs net: prevent deadlocks when enabling NAPIs with mixed kthread config include/linux/netdevice.h | 5 ++++- net/core/dev.h | 8 ++++++++ net/core/dev.c | 12 +++++++++--- tools/testing/selftests/drivers/net/napi_threaded.py | 10 ++++++---- 4 files changed, 27 insertions(+), 8 deletions(-) -- 2.50.1

[PATCH v2 0/2] selftests/fchmodat2: Error handling and general cleanups

[PATCH v5 00/15] kunit: Introduce UAPI testing framework

by Thomas Weißschuh

Currently testing of userspace and in-kernel API use two different frameworks. kselftests for the userspace ones and Kunit for the in-kernel ones. Besides their different scopes, both have different strengths and limitations: Kunit: * Tests are normal kernel code. * They use the regular kernel toolchain. * They can be packaged and distributed as modules conveniently. Kselftests: * Tests are normal userspace code * They need a userspace toolchain. A kernel cross toolchain is likely not enough. * A fair amout of userland is required to run the tests, which means a full distro or handcrafted rootfs. * There is no way to conveniently package and run kselftests with a given kernel image. * The kselftests makefiles are not as powerful as regular kbuild. For example they are missing proper header dependency tracking or more complex compiler option modifications. Therefore kunit is much easier to run against different kernel configurations and architectures. This series aims to combine kselftests and kunit, avoiding both their limitations. It works by compiling the userspace kselftests as part of the regular kernel build, embedding them into the kunit kernel or module and executing them from there. If the kernel toolchain is not fit to produce userspace because of a missing libc, the kernel's own nolibc can be used instead. The structured TAP output from the kselftest is integrated into the kunit KTAP output transparently, the kunit parser can parse the combined logs together. Further room for improvements: * Call each test in its completely dedicated namespace * Handle additional test files besides the test executable through archives. CPIO, cramfs, etc. * Compatibility with kselftest_harness.h (in progress) * Expose the blobs in debugfs * Provide some convience wrappers around compat userprogs * Figure out a migration path/coexistence solution for kunit UAPI and tools/testing/selftests/ Output from the kunit example testcase, note the output of "example_uapi_tests". $ ./tools/testing/kunit/kunit.py run --kunitconfig lib/kunit example ...

[PATCH net-next 0/3] bonding: support aggregator selection based on port priority

by Hangbin Liu

This patchset introduces a new per-port bonding option: `ad_actor_port_prio`. It allows users to configure the actor's port priority, which can then be used by the bonding driver for aggregator selection based on port priority. This provides finer control over LACP aggregator choice, especially in setups with multiple eligible aggregators over 2 switches.

[PATCH v2] selftests/net: Ensure assert() triggers in psock_tpacket.c

by Wake Liu

The get_next_frame() function in psock_tpacket.c was missing a return statement in its default switch case, leading to a compiler warning. This was caused by a `bug_on(1)` call, which is defined as an `assert()`, being compiled out because NDEBUG is defined during the build. Instead of adding a `return NULL;` which would silently hide the error and could lead to crashes later, this change restores the original author's intent. By adding `#undef NDEBUG` before including <assert.h>, we ensure the assertion is active and will cause the test to abort if this unreachable code is ever executed.

[PATCH] selftests/net: Replace non-standard __WORDSIZE with sizeof(long) * 8

by Wake Liu

The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>` header, is a GNU extension and not universally available with all toolchains, such as Clang when used with musl libc. This can lead to build failures in environments where this header is missing. The intention of the code is to determine the bit width of a C `long`. Replace the non-portable `__WORDSIZE` with the standard and portable `sizeof(long) * 8` expression to achieve the same result. This change also removes the inclusion of the now-unused `<bits/wordsize.h>` header.

[PATCH net] bonding: don't set oif to bond dev when getting NS target destination

by Hangbin Liu

Unlike IPv4, IPv6 routing strictly requires the source address to be valid on the outgoing interface. If the NS target is set to a remote VLAN interface, and the source address is also configured on a VLAN over a bond interface, setting the oif to the bond device will fail to retrieve the correct destination route. Fix this by not setting the oif to the bond device when retrieving the NS target destination. This allows the correct destination device (the VLAN interface) to be determined, so that bond_verify_device_path can return the proper VLAN tags for sending NS messages.
