From e6854be4d80ea266a7be64a65a0322bcdfa72807 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 3 Jun 2025 18:20:55 -0700 Subject: [PATCH] selftests: drv-net: tso: make bkg() wait for socat to quit Commit 846742f7e32f ("selftests: drv-net: add a warning for bkg + shell + terminate") added a warning for bkg() used with terminate=True. The tso test was missed as we didn't have it running anywhere in NIPA. Add exit_wait=True, to avoid: # Warning: combining shell and terminate is risky! # SIGTERM may not reach the child on zsh/ksh! getting printed twice for every variant.
