It also does not work in some cases where only a subset of tests are exported (2). Avoid the problems mentioned above by replacing the faulty expression with a copy of the content from net/lib.sh which is used by files under net/forwarding. A more thorough solution which avoids duplicating content between net/lib.sh and net/forwarding/lib.sh has been posted here: https://lore.kernel.org/netdev/20231222135836.992841-1-bpoirier@nvidia.com/ The approach in the current patch is a stopgap solution to avoid submitting large changes at the eleventh hour of this development cycle. Example of problem 1) tools/testing/selftests/drivers/net/bonding$ ./dev_addr_lists.sh ./net_forwarding_lib.sh: line 41: ../lib.sh: No such file or directory TEST: bonding cleanup mode active-backup [ OK ] TEST: bonding cleanup mode 802.3ad [ OK ] TEST: bonding LACPDU multicast address to slave (from bond down) [ OK ] TEST: bonding LACPDU multicast address to slave (from bond up) [ OK ] An error message is printed but since the test does not use functions from net/lib.sh, the test results are not affected. Example of problem 2) tools/testing/selftests$ make install TARGETS="net/forwarding" tools/testing/selftests$ cd kselftest_install/net/forwarding/ tools/testing/selftests/kselftest_install/net/forwarding$ ./pedit_ip.sh veth{0..3} lib.sh: line 41: ../lib.sh: No such file or directory TEST: ping [ OK ] TEST: ping6 [ OK ] ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip src set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip src set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip dst set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip dst set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip6 src set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip6 src set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip6 dst set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip6 dst set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . In this case, the test results are affected.
