bpf: sockmap, remove samples program

2018-04-24T22:06:21+00:00

The BPF sample sockmap is redundant now that equivelant tests exist
in the BPF selftests. Lets remove this sample and only keep the
selftest version that will be run as part of the selftest suite.

bpf: sockmap, add a set of tests to run by default

2018-04-24T22:04:49+00:00

If no options are passed to sockmap after this patch we run a set of
tests using various options and sendmsg/sendpage sizes. This replaces
the sockmap_test.sh script.

bpf: sockmap, code sockmap_test in C

2018-04-24T22:04:49+00:00

By moving sockmap_test from shell script into C we can run it directly
from selftests, but we can also push the input/output around in proper
structures.

However, keep the CLI options around because they are useful for
debugging when a paticular pattern of msghdr or sockmap options
trips up the sockmap code path.

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, add BPF_F_INGRESS tests

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

Add a set of tests to verify ingress flag in redirect helpers
works correctly with various msg sizes.

bpf: sockmap test script

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

This adds the test script I am currently using to validate
the latest sockmap changes. Shortly sockmap will be ported
to selftests and these will be run from the infrastructure
there. Until then add the script here so we have a coverage
checklist when porting into selftests.

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.
