selftests/bpf: fix netdevsim trap_flow_action_cookie read

2020-07-30T23:33:07+00:00

When read netdevsim trap_flow_action_cookie, we need to init it first,
or we will get "Invalid argument" error.

selftests: bpf: log direct file writes

2019-11-06T17:59:58+00:00

Recent changes to netdevsim moved creating and destroying
devices from netlink to sysfs. The sysfs writes have been
implemented as direct writes, without shelling out. This
is faster, but leaves no trace in the logs. Add explicit
logs to make debugging possible.

bpf: re-fix skip write only files in debugfs

2019-11-04T19:34:34+00:00

Commit 5bc60de50dfe ("selftests: bpf: Don't try to read files without
read permission") got reverted as the fix was not working as expected
and real fix came in via 8101e069418d ("selftests: bpf: Skip write
only files in debugfs"). When bpf-next got merged into net-next, the
test_offload.py had a small conflict. Fix the resolution in ae8a76fb8b5d
iby not reintroducing 5bc60de50dfe again.

The only slightly tricky merge conflict was the netdevsim because the
mutex locking fix overlapped a lot of driver reload reorganization.

The rest were (relatively) trivial in nature.

selftests: bpf: Skip write only files in debugfs

2019-11-01T22:16:01+00:00

DebugFS for netdevsim now contains some "action trigger" files
which are write only. Don't try to capture the contents of those.

Note that we can't use os.access() because the script requires
root.

Revert "selftests: bpf: Don't try to read files without read permission"

2019-11-01T12:13:21+00:00

This reverts commit 5bc60de50dfe ("selftests: bpf: Don't try to read
files without read permission").

Quoted commit does not work at all, and was never tested.
Script requires root permissions (and tests for them)
and os.access() will always return true for root.

The correct fix is needed in the bpf tree, so let's just
revert and save ourselves the merge conflict.

selftests: bpf: Don't try to read files without read permission

2019-10-15T23:27:25+00:00

Recently couple of files that are write only were added to netdevsim
debugfs. Don't read these files and avoid error.

netdevsim: move netdev creation/destruction to dev probe

2019-04-26T05:52:03+00:00

Remove the existing way to create netdevsim over rtnetlink and move the
netdev creation/destruction to dev probe, so for every probed port,
a netdevsim-netdev instance is created.

Adjust selftests to work with new interface.
