linux.git/tools/testing/selftests/net/lib.sh, branch v6.9 Linux kernel source tree selftests/net/lib: update busywait timeout value 2024-01-26T01:07:14+00:00 Hangbin Liu liuhangbin@gmail.com 2024-01-24T06:13:44+00:00 fc836129f708407502632107e58d48f54b1caf75 The busywait timeout value is a millisecond, not a second. So the current setting 2 is too small. On slow/busy host (or VMs) the current timeout can expire even on "correct" execution, causing random failures. Let's copy the WAIT_TIMEOUT from forwarding/lib.sh and set BUSYWAIT_TIMEOUT here.

selftests/net: add variable NS_LIST for lib.sh 2023-12-15T02:38:34+00:00 Hangbin Liu liuhangbin@gmail.com 2023-12-13T06:08:44+00:00 b6925b4ed57cccf42ca0fb46c7446f0859e7ad4b Add a global variable NS_LIST to store all the namespaces that setup_ns created, so the caller could call cleanup_all_ns() instead of remember all the netns names when using cleanup_ns().

This file can be used to define commonly used variables and functions. Some commonly used functions can be moved from forwarding/lib.sh to this lib file. e.g. busywait().
