The only exception is the introduction of packet streams that describes what the Tx process should send and what the Rx process should receive. If it receives anything else, the test fails. This mechanism can be used to produce tests were all packets are not received by the Rx thread or modified in some way. An example of this is if an XDP program does XDP_PASS on some of the packets. This patch set will be followed by another patch set that implements a new structure that will facilitate adding new tests. A couple of new tests will also be included in that patch set. v2 -> v3: * Reworked patch 12 so that it now has functions for creating and destroying ifobjects. Simplifies the code. [Maciej] * The packet stream now allocates the supplied buffer array length, instead of the default one. [Maciej] * pkt_stream_get_pkt() now returns NULL when indexing a non-existing packet. [Maciej] * pkt_validate() is now is_pkt_valid(). [Maciej] * Slowed down packet sending speed even more in patch 11 so that slow systems do not silenty drop packets in skb mode. v1 -> v2: * Dropped the patch with per process limit changes as it is not needed [Yonghong] * Improved the commit message of patch 1 [Yonghong] * Fixed a spelling error in patch 9 Thanks: Magnus Magnus Karlsson (16): selftests: xsk: remove color mode selftests: xsk: remove the num_tx_packets option selftests: xsk: remove unused variables selftests: xsk: return correct error codes selftests: xsk: simplify the retry code selftests: xsk: remove end-of-test packet selftests: xsk: disassociate umem size with packets sent selftests: xsk: rename worker_* functions that are not thread entry points selftests: xsk: simplify packet validation in xsk tests selftests: xsk: validate tx stats on tx thread selftests: xsk: decrease sending speed selftests: xsk: simplify cleanup of ifobjects selftests: xsk: generate packet directly in umem selftests: xsk: generate packets from specification selftests: xsk: make enums lower case selftests: xsk: preface options with opt tools/testing/selftests/bpf/test_xsk.sh | 10 +- tools/testing/selftests/bpf/xdpxceiver.c | 681 ++++++++++----------- tools/testing/selftests/bpf/xdpxceiver.h | 63 +- tools/testing/selftests/bpf/xsk_prereqs.sh | 30 +- 4 files changed, 356 insertions(+), 428 deletions(-) base-commit: 3bbc8ee7c363a83aa192d796ad37b6bf462a2947 Acked-by: Maciej Fijalkowski --- 2.29.0
