From a7ee79b9c4553498c78552d12321d85b645f02ca Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Mon, 12 Feb 2024 10:43:31 +0100 Subject: [PATCH] selftests: net: cope with slow env in so_txtime.sh test The mentioned test is failing in slow environments: # SO_TXTIME ipv4 clock monotonic # ./so_txtime: recv: timeout: Resource temporarily unavailable not ok 1 selftests: net: so_txtime.sh # exit=1 Tuning the tolerance in the test binary is error-prone and doomed to failures is slow-enough environment. Just resort to suppress any error in such cases. Note to suppress them we need first to refactor a bit the code moving it to explicit error handling.
