selftests: netconsole: Increase port listening timeout

2026-02-26T23:01:30+00:00

[ Upstream commit a68a9bd086c2822d0c629443bd16ad1317afe501 ] wait_for_port() can wait up to 2 seconds with the sleep and the polling in wait_local_port_listen() combined. So, in netcons_basic.sh, the socat process could die before the test writes to the netconsole. Increase the timeout to 3 seconds to make netcons_basic.sh pass consistently.

selftests: mlxsw: tc_restrictions: Fix test failure with new iproute2

2026-02-26T23:01:29+00:00

[ Upstream commit a2646773a005b59fd1dc7ff3ba15df84889ca5d2 ] As explained in [1], iproute2 started rejecting tc-police burst sizes that result in an overflow. This can happen when the burst size is high enough and the rate is low enough. A couple of test cases specify such configurations, resulting in iproute2 errors and test failure. Fix by reducing the burst size so that the test will pass with both new and old iproute2 versions.

selftests: drv-net: fix RPS mask handling for high CPU numbers

2026-01-14T03:13:08+00:00

The RPS bitmask bounds check uses ~(RPS_MAX_CPUS - 1) which equals ~15 = 0xfff0, only allowing CPUs 0-3. Change the mask to ~((1UL << RPS_MAX_CPUS) - 1) = ~0xffff to allow CPUs 0-15.

selftests: drv-net: fix RPS mask handling in toeplitz test

2026-01-14T03:13:08+00:00

The toeplitz.py test passed the hex mask without "0x" prefix (e.g., "300" for CPUs 8,9). The toeplitz.c strtoul() call wrongly parsed this as decimal 300 (0x12c) instead of hex 0x300. Pass the prefixed mask to toeplitz.c, and the unprefixed one to sysfs.

selftests: netdevsim: add carrier state consistency test

2026-01-07T02:04:01+00:00

This commit adds a test case for netdevsim carrier state consistency. Specifically, the added test verifies the carrier state during the following operations: 1. Unlink two netdevsims 2. ifdown one netdevsim, then ifup again 3. Link the netdevsims again 4. ifdown one netdevsim, then ifup again These steps verifies that the carrier is UP iff two netdevsims are linked and ifuped.

Also preparation for LUO - "Live Update Orchestrator" (Pasha Tatashin) is a major new feature targeted at cloud environments. Quoting the cover letter: This series introduces the Live Update Orchestrator, a kernel subsystem designed to facilitate live kernel updates using a kexec-based reboot. This capability is critical for cloud environments, allowing hypervisors to be updated with minimal downtime for running virtual machines. LUO achieves this by preserving the state of selected resources, such as memory, devices and their dependencies, across the kernel transition. As a key feature, this series includes support for preserving memfd file descriptors, which allows critical in-memory data, such as guest RAM or any other large memory region, to be maintained in RAM across the kexec reboot. Mike Rappaport merits a mention here, for his extensive review and testing work. - "kexec: reorganize kexec and kdump sysfs" (Sourabh Jain) moves the kexec and kdump sysfs entries from /sys/kernel/ to /sys/kernel/kexec/ and adds back-compatibility symlinks which can hopefully be removed one day - "kho: fixes for vmalloc restoration" (Mike Rapoport) fixes a BUG which was being hit during KHO restoration of vmalloc() regions * tag 'mm-nonmm-stable-2025-12-06-11-14' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (139 commits) calibrate: update header inclusion Reinstate "resource: avoid unnecessary lookups in find_next_iomem_res()" vmcoreinfo: track and log recoverable hardware errors kho: fix restoring of contiguous ranges of order-0 pages kho: kho_restore_vmalloc: fix initialization of pages array MAINTAINERS: TPM DEVICE DRIVER: update the W-tag init: replace simple_strtoul with kstrtoul to improve lpj_setup KHO: fix boot failure due to kmemleak access to non-PRESENT pages Documentation/ABI: new kexec and kdump sysfs interface Documentation/ABI: mark old kexec sysfs deprecated kexec: move sysfs entries to /sys/kernel/kexec test_kho: always print restore status kho: free chunks using free_page() instead of kfree() selftests/liveupdate: add kexec test for multiple and empty sessions selftests/liveupdate: add simple kexec-based selftest for LUO selftests/liveupdate: add userspace API selftests docs: add documentation for memfd preservation via LUO mm: memfd_luo: allow preserving memfd liveupdate: luo_file: add private argument to store runtime state mm: shmem: export some functions to internal.h ...
