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.

   increases the flexibility of KEXEC Handover. 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.

   moves the kexec and kdump sysfs entries from /sys/kernel/ to

selftests: drv-net: Fix tolerance calculation in devlink_rate_tc_bw.py

2025-12-02T01:18:41+00:00

Currently, tolerance is computed against the TC’s expected percentage,
making TC3 (20%) validation overly strict and TC4 (80%) overly loose.

Update BandwidthValidator to take a dict of shares and compute bounds
relative to the overall total, so that all shares are validated
consistently.
