[PATCH v3 0/1] Add KUnit tests for llist

by Artur Alves

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 the llist data structure, defined in include/linux/llist.h, and is inspired by the KUnit tests for the doubly linked list in lib/list-test.c[3]. It is important to note that this patch depends on the patch referenced in [4], as it utilizes the newly created lib/tests/ subdirectory.

[PATCH slab hotfixes 0/2] slub kunit tests fixes for 6.12

by Vlastimil Babka

The SLUB changes for 6.12 included new kunit tests that resulted in noisy warnings, which we normally suppress, and a boot lockup in some configurations in case the kunit tests are built-in. The warnings are addressed in Patch 1. The lockups I couldn't reproduce, but inspecting boot initialization order makes me suspect the tests (which call few RCU operations) are being executed a bit too early before RCU finishes initialization. Moving the exection later seems to do the trick, so I'd like to ask kunit folks to ack this change (Patch 2). If RCU folks have any insights, it would be welcome too. So these are now fixes for 4e1c44b3db79 ("kunit, slub: add test_kfree_rcu() and test_leak_destroy()") Once sent as a full patch, I also want to include comment fixes from Ulad for kvfree_rcu_queue_batch(): https://lore.kernel.org/all/CA%2BKHdyV%3D0dpJX_v_tcuTQ-_ree-Yb9ch3F_HqfT4Yn… The plan is to take the fixes via slab tree for a 6.12 rcX.

step_after_suspend_test fails with device busy error while writing to /sys/power/state to start suspend.

It should be caused by the write function is not successfully returned before the system suspend and the return value get messed when waking up. As a result, It may be better to check the time passed of those few instructions to determine whether the suspend is executed correctly for it is pretty hard to execute those few lines for 5 seconds. The timer to wake up the system is set to expire after 5 seconds and no re-arm. If the timer remaining time is 0 second and 0 nano secomd, it means the timer expired and wake the system up. Otherwise, the system could be considered to enter the suspend state failed if there is any remaining time. After appling this patch, the test would not fail for it believes the system does not go to suspend by mistake. It now could continue to the rest part of the test after suspend.

[PATCH RFC v3 0/2] mm: Introduce ADDR_LIMIT_47BIT personality flag

by Charlie Jenkins

Some applications rely on placing data in free bits addresses allocated by mmap. Various architectures (eg. x86, arm64, powerpc) restrict the address returned by mmap to be less than the 48-bit address space, unless the hint address uses more than 47 bits (the 48th bit is reserved for the kernel address space). The riscv architecture needs a way to similarly restrict the virtual address space. On the riscv port of OpenJDK an error is thrown if attempted to run on the 57-bit address space, called sv57 [1]. golang has a comment that sv57 support is not complete, but there are some workarounds to get it to mostly work [2]. These applications work on x86 because x86 does an implicit 47-bit restriction of mmap() address that contain a hint address that is less than 48 bits. Instead of implicitly restricting the address space on riscv (or any current/future architecture), provide a flag to the personality syscall that can be used to ensure an application works in any arbitrary VA space. A similar feature has already been implemented by the personality syscall in ADDR_LIMIT_32BIT. This flag will also allow seemless compatibility between all architectures, so applications like Go and OpenJDK that use bits in a virtual address can request the exact number of bits they need in a generic way. The flag can be checked inside of vm_unmapped_area() so that this flag does not have to be handled individually by each architecture.

[PATCH RFC v4 0/9] tun: Introduce virtio-net hashing feature

by Akihiko Odaki

virtio-net have two usage of hashes: one is RSS and another is hash reporting. Conventionally the hash calculation was done by the VMM. However, computing the hash after the queue was chosen defeats the purpose of RSS. Another approach is to use eBPF steering program. This approach has another downside: it cannot report the calculated hash due to the restrictive nature of eBPF. Introduce the code to compute hashes to the kernel in order to overcome thse challenges. An alternative solution is to extend the eBPF steering program so that it will be able to report to the userspace, but it is based on context rewrites, which is in feature freeze. We can adopt kfuncs, but they will not be UAPIs. We opt to ioctl to align with other relevant UAPIs (KVM and vhost_net). The patches for QEMU to use this new feature was submitted as RFC and is available at: https://patchew.org/QEMU/20240915-hash-v3-0-79cb08d28647@daynix.com/ This work was presented at LPC 2024: https://lpc.events/event/18/contributions/1963/ V1 -> V2: Changed to introduce a new BPF program type.
