bpf: sockmap, more BPF_SK_SKB_STREAM_VERDICT tests

2018-03-29T22:09:43+00:00

Add BPF_SK_SKB_STREAM_VERDICT tests for ingress hook. While
we do this also bring stream tests in-line with MSG based
testing.

A map for skb options is added for userland to push options
at BPF programs.

bpf: sockmap sample test for bpf_msg_pull_data

2018-03-19T20:14:41+00:00

This adds an option to test the msg_pull_data helper. This
uses two options txmsg_start and txmsg_end to let the user
specify start and end bytes to pull.

The options can be used with txmsg_apply, txmsg_cork options
as well as with any of the basic tests, txmsg, txmsg_redir and
txmsg_drop (plus noisy variants) to run pull_data inline with
those tests. By giving user direct control over the variables
we can easily do negative testing as well as positive tests.

bpf: sockmap sample support for bpf_msg_cork_bytes()

2018-03-19T20:14:40+00:00

Add sample application support for the bpf_msg_cork_bytes helper. This
lets the user specify how many bytes each verdict should apply to.

Similar to apply_bytes() tests these can be run as a stand-alone test
when used without other options or inline with other tests by using
the txmsg_cork option along with any of the basic tests txmsg,
txmsg_redir, txmsg_drop.

bpf: sockmap, add sample option to test apply_bytes helper

2018-03-19T20:14:40+00:00

This adds an option to test the apply_bytes helper. This option lets
the user specify an int on the command line specifying how much data
each verdict should apply to.

When this is set a map entry is set with the bytes input by the user
and then the specified program --txmsg or --txmsg_redir will use the
value and set the applied data. If no other option is set then a
default --txmsg_apply program is run. This program will drop pkts
if an error is detected on the bytes map lookup. Useful to verify
the map lookup and apply helper are working and causing a hard
error if it is not.

To exercise TX ULP sendpage implementation we need a test that does
a sendfile. Add sendfile test option here.

bpf: samples/sockmap detach sock ops program

2018-02-14T01:46:53+00:00

samples/sockops program keeps the sock_ops program attached to cgroup.
Fixed this by detaching program before exit.
