Subject: [PATCH net-next 0/3] selftests: net: py: improve bkg() error reporting
Date: Mon, 23 Feb 2026 12:26:30 -0800 [thread overview]
Message-ID: <20260223202633.4126087-1-kuba@kernel.org> (raw)
bkg() is a helper for running commands in the background.
When init or body of a with() block fails check if the bkg()
process already exited and report its status (including stdout/
/stderr). This significantly improves debugability.
Jakub Kicinski (3):
selftests: net: py: avoid masking exceptions in bkg() failures
selftests: net: py: use repr(cmd) for failure exceptions
selftests: net: py: add cmd info for ksft_wait failure
