Change the dmesg parsing to filter on strings containing 'vsock' to avoid false positive failures that are unrelated to vsock. The downside is that it is possible for some vsock related warnings to not contain the substring 'vsock', so those will be missed.

It uses virtme-ng/qemu to run tests in a VM. The tests validate G2H, H2G, and loopback. The testing tools from tools/testing/vsock/ are reused. Currently, only vsock_test is used. VMCI and hyperv support is included in the config file to be built with the -b option, though not used in the tests. Only tested on x86. To run: $ make -C tools/testing/selftests TARGETS=vsock $ tools/testing/selftests/vsock/vmtest.sh or $ make -C tools/testing/selftests TARGETS=vsock run_tests Example runs (after make -C tools/testing/selftests TARGETS=vsock): $ ./tools/testing/selftests/vsock/vmtest.sh 1..3 ok 0 vm_server_host_client ok 1 vm_client_host_server ok 2 vm_loopback SUMMARY: PASS=3 SKIP=0 FAIL=0 Log: /tmp/vsock_vmtest_m7DI.log $ ./tools/testing/selftests/vsock/vmtest.sh vm_loopback 1..1 ok 0 vm_loopback SUMMARY: PASS=1 SKIP=0 FAIL=0 Log: /tmp/vsock_vmtest_a1IO.log $ mkdir -p ~/scratch $ make -C tools/testing/selftests install TARGETS=vsock INSTALL_PATH=~/scratch [... omitted ...] $ cd ~/scratch $ ./run_kselftest.sh TAP version 13 1..1 # timeout set to 300 # selftests: vsock: vmtest.sh # 1..3 # ok 0 vm_server_host_client # ok 1 vm_client_host_server # ok 2 vm_loopback # SUMMARY: PASS=3 SKIP=0 FAIL=0 # Log: /tmp/vsock_vmtest_svEl.log ok 1 selftests: vsock: vmtest.sh Future work can include vsock_diag_test. Because vsock requires a VM to test anything other than loopback, this patch adds vmtest.sh as a kselftest itself. This is different than other systems that have a "vmtest.sh", where it is used as a utility script to spin up a VM to run the selftests as a guest (but isn't hooked into kselftest).
