  "message": "selftests: net: py: avoid masking exceptions in bkg() failures\n\nbkg() failures are currently quite hard to debug and spot.\nOften we have code along the lines of:\n\n  with bkg(\"./cmd_rx_something -p PORT\"):\n       wait_port_listen(PORT)\n       cmd(\"./cmd_tx_something\", host\u003dremote)\n\nWhen wait_port_listen() fails we don\u0027t get to see the exit status\nof bkg(). Even tho very often it\u0027s a failure in the bkg() command\nthat\u0027s actually to blame. Try not to interfere with the bkg()\ncommand error checking.\n\nWith:\n\n   with bkg(\"false\", exit_wait\u003dTrue):\n        time.sleep(0.01)  # let the \u0027false\u0027 cmd run\n        raise Exception(\"bla\")\n\nBefore:\n\n  .. stack trace ..\n  # Exception| Exception: bla\n\nAfter:\n\n  .. stack trace ..\n  # Exception| Exception: bla\n  # Exception|\n  # Exception| During handling of the above exception, another exception occurred:\n  .. stack trace ..\n  # Exception| lib.py.utils.CmdExitFailure: Command failed: false\n  # Exception| STDOUT: b\u0027\u0027\n  # Exception| STDERR: b\u0027\u0027\n\nReviewed-by: Petr Machata \u003cpetrm@nvidia.com\u003e\nReviewed-by: Simon Horman \u003chorms@kernel.org\u003e\nLink: https://patch.msgid.link/20260223202633.4126087-2-kuba@kernel.org\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
