selftests: extend zerocopy tests to udp

2018-12-03T23:58:32Z

Both msg_zerocopy and udpgso_bench have udp zerocopy variants. Exercise these as part of the standard kselftest run. With udp, msg_zerocopy has no control channel. Ensure that the receiver exits after the sender by accounting for the initial delay in starting them (in msg_zerocopy.sh). Signed-off-by: Willem de Bruijn Signed-off-by: David S. Miller

selftests/net: reap zerocopy completions passed up as ancillary data.

2018-02-27T19:19:11Z

PF_RDS sockets pass up cookies for zerocopy completion as ancillary data. Update msg_zerocopy to reap this information. Signed-off-by: Sowmini Varadhan Acked-by: Willem de Bruijn Acked-by: Santosh Shilimkar Signed-off-by: David S. Miller

selftests/net: revert the zerocopy Rx path for PF_RDS

2018-02-27T19:19:10Z

In preparation for optimized reception of zerocopy completion, revert the Rx side changes introduced by Commit dfb8434b0a94 ("selftests/net: add zerocopy support for PF_RDS test case") Signed-off-by: Sowmini Varadhan Acked-by: Willem de Bruijn Acked-by: Santosh Shilimkar Signed-off-by: David S.

selftests/net: fix bugs in address and port initialization

2018-01-02T18:26:58Z

Address/port initialization should work correctly regardless of the order in which command line arguments are supplied, E.g, cfg_port should be used to connect to the remote host even if it is processed after -D, src/dst address initialization should not require that [-4|-6] be specified before the -S or -D args, receiver should be able to bind to *. Achieve this by making sure that the address/port structures are initialized after all command line options are parsed. Store cfg_port in host-byte order, and use htons() to set up the sin_port/sin6_port before bind/connect, so that the network system calls get the correct values in network-byte order.

selftests/net: msg_zerocopy enable build with older kernel headers

2017-09-19T20:12:29Z

Explicitly define SO_EE_ORIGIN_ZEROCOPY. This makes the test program build with older kernel headers, e.g. from Debian 9. Signed-off-by: Thomas Meyer Signed-off-by: Shuah Khan

selftests: correct define in msg_zerocopy.c

2017-09-01T17:41:21Z

The msg_zerocopy test defines SO_ZEROCOPY if necessary, but its value is inconsistent with the one in asm-generic.h. Correct that. Also convert one error to a warning. When the test is complete, report throughput and close cleanly even if the process did not wait for all completions.

test: add msg_zerocopy test

2017-08-04T04:37:30Z

Introduce regression test for msg_zerocopy feature. Send traffic from one process to another with and without zerocopy. Evaluate tcp, udp, raw and packet sockets, including variants - udp: corking and corking with mixed copy/zerocopy calls - raw: with and without hdrincl - packet: at both raw and dgram level Test on both ipv4 and ipv6, optionally with ethtool changes to disable scatter-gather, tx checksum or tso offload. All of these can affect zerocopy behavior. The regression test can be run on a single machine if over a veth pair. Then skb_orphan_frags_rx must be modified to be identical to skb_orphan_frags to allow forwarding zerocopy locally. The msg_zerocopy.sh script will setup the veth pair in network namespaces and run all tests. Signed-off-by: Willem de Bruijn Signed-off-by: David S. Miller
