This series attempts to improve the xsk selftest framework by: 1. making the default output less verbose 2. adding an optional verbose flag to both the test_xsk.sh script and xdpxceiver app. 3. renaming the debug option in the app to to 'dump-pkts' and add a flag to the test_xsk.sh script which enables the flag in the app. 4. changing how tests are launched - now they are launched from the xdpxceiver app instead of the script. Once the improvements are made, a new set of tests are added which test the xsk statistics. The output of the test script now looks like: ./test_xsk.sh PREREQUISITES: [ PASS ] 1..10 ok 1 PASS: SKB NOPOLL ok 2 PASS: SKB POLL ok 3 PASS: SKB NOPOLL Socket Teardown ok 4 PASS: SKB NOPOLL Bi-directional Sockets ok 5 PASS: SKB NOPOLL Stats ok 6 PASS: DRV NOPOLL ok 7 PASS: DRV POLL ok 8 PASS: DRV NOPOLL Socket Teardown ok 9 PASS: DRV NOPOLL Bi-directional Sockets ok 10 PASS: DRV NOPOLL Stats # Totals: pass:10 fail:0 xfail:0 xpass:0 skip:0 error:0 XSK KSELFTESTS: [ PASS ] v1->v2: * Changed '-d' flag in the shell script to '-D' to be consistent with the xdpxceiver app. * Renamed debug mode to 'dump-pkts' which better reflects the behaviour. * Use libpf APIs instead of calls to ss for configuring xdp on the links * Remove mutex init & destroy for each stats test * Added a description for each of the new statistics tests * Distinguish between exiting due to initialisation failure vs test failure This series applies on commit d310ec03a34e92a77302edb804f7d68ee4f01ba0 Ciara Loftus (3): selftests/bpf: expose and rename debug argument selftests/bpf: restructure xsk selftests selftests/bpf: introduce xsk statistics tests Magnus Karlsson (1): selftest/bpf: make xsk tests less verbose tools/testing/selftests/bpf/test_xsk.sh | 129 ++----- tools/testing/selftests/bpf/xdpxceiver.c | 380 +++++++++++++++------ tools/testing/selftests/bpf/xdpxceiver.h | 57 +++- tools/testing/selftests/bpf/xsk_prereqs.sh | 30 +- 4 files changed, 336 insertions(+), 260 deletions(-) -- 2.17.1
