[PATCH AUTOSEL 6.6 9/9] kselftest/arm64: Don't leak pipe fds in pac.exec_sign_all()

by Sasha Levin

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 27141b690547da5650a420f26ec369ba142a9ebb ] The PAC exec_sign_all() test spawns some child processes, creating pipes to be stdin and stdout for the child. It cleans up most of the file descriptors that are created as part of this but neglects to clean up the parent end of the child stdin and stdout. Add the missing close() calls.

[PATCH AUTOSEL 6.6 8/9] kselftest/arm64: Corrupt P0 in the irritator when testing SSVE

by Sasha Levin

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 3e360ef0c0a1fb6ce9a302e40b8057c41ba8a9d2 ] When building for streaming SVE the irritator for SVE skips updates of both P0 and FFR. While FFR is skipped since it might not be present there is no reason to skip corrupting P0 so switch to an instruction valid in streaming mode and move the ifdef.

[PATCH AUTOSEL 6.6 2/9] kselftest/arm64: Log fp-stress child startup errors to stdout

by Sasha Levin

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit dca93d29845dfed60910ba13dbfb6ae6a0e19f6d ] Currently if we encounter an error between fork() and exec() of a child process we log the error to stderr. This means that the errors don't get annotated with the child information which makes diagnostics harder and means that if we miss the exit signal from the child we can deadlock waiting for output from the child. Improve robustness and output quality by logging to stdout instead.
