tests: add spdx license header to test unit/link/network/conf files Those are all consumed by our parser, so they all support comments. I was considering whether they should have a license header at all, but in the end I decided to add it because those files are often created by copying parts of real unit files. And if the real ones have a license, then those might as well. It's easier to add it than to make an exception. 2021-10-17 16:07:22 +00:00			`# SPDX-License-Identifier: LGPL-2.1-or-later`

test: make test-execute pass on Linux 5.15 Linux 5.15 broke kernel API: https://github.com/torvalds/linux/commit/e70344c05995a190a56bbd1a23dc2218bcc8c924 Previously setting IOPRIO_CLASS_NONE for a process would then report IOPRIO_CLASS_NONE back. But since 5.15 it reports IOPRIO_CLASS_BE instead. Since IOPRIO_CLASS_NONE is an alias for a special setting of IOPRIO_CLASS_BE this makes some sense, but it's also a kernel API breakage that our testsuite trips up on. (I made some minimal effort to inform the kernel people about this API breakage during the 5.15 rc phase, but noone was interested.) Either way let's hadle this gracefully in our test suite and accept "best-effort" too when "none" was set. (This is only triggable if the tests are run on 5.15 with full privs) 2021-11-24 14:58:50 +00:00			`# Old kernels might report "none" here, new kernels "best-effort".`
tests: use relative paths in ExecStart= and friends We want to retain some of the full paths in order to test more code paths. But the default should be to use the command name only. This makes the tests less visually cluttered. 2024-01-04 14:24:52 +00:00			`ExecStart=sh -x -c 'c=$$(LC_ALL=C ionice); test "$${c%%:}" = "none" -o "$${c%%:}" = "best-effort"'`
