[PATCH 0/3] selftests/nolibc: enable qemu-system tests with LLVM builds

by Thomas Weißschuh

Currently the test setup does not support running nolibc-test built with LLVM in qemu-system. Enable this. FYI, sparc32 on LLVM seems to be broken at the moment. To me this looks like a LLVM regression, emitting invalid object code.

[PATCH net] selftests: rtnetlink: fix addrlft test flakiness on power-saving systems

by Hangbin Liu

Jakub reported that the rtnetlink test for the preferred lifetime of an address has become quite flaky. The issue started appearing around the 6.16 merge window in May, and the test fails with: FAIL: preferred_lft addresses remaining The flakiness might be related to power-saving behavior, as address expiration is handled by a "power-efficient" workqueue. To address this, use slowwait to check more frequently whether the address still exists. This reduces the likelihood of the system entering a low-power state during the test, improving reliability.
