gnrc_tcp: rewrite passive open #16459

brummer-simon · 2021-05-08T07:20:59Z

Contribution description

This PR rewrites the passive connection establishment mechanism of GNRC_TCP.
The new version aligns the GNRC_TCP interface with the SOCK_TCP interface with the goal to make a upcoming SOCK integration straight forward and trivial.

Since this is a large change, I've split the PR into three commits (api, implementation and tests) to help reviewing this.
The new tests are written in different style than existing tests, please ignore the difference in style for now, I plan to align the existing test structure in a dedicated PR on after merging this.

Testing procedure

This PR is covered by the GNRC_TCP test suite.
To test this PR follow the instructions under tests/gnrc_tcp/Readme.md

Issues/PRs references

Fixes #10664 - TCP Sockets can not be used / built

MrKevinWeiss · 2021-06-24T11:55:01Z

Should we move this to next release as it is soft feature freeze and this contains an API change?

brummer-simon · 2021-06-24T13:11:09Z

This PR and the followup PR contain large API changes. Although the changes are tested in depth, it might be much effort to review all of this. I personally don't care if this is part of this release or the next. From my side, do whatever relaxes your release management. ;)

This looks good at a cursory glance

Looks good to me, Murdock should ensure that the tests are still passing on native.

Looks good to me, Murdock should ensure that the tests are still passing on native.

Given that the tests require root it probably doesn't ;-).

benpicco · 2021-07-04T19:45:49Z

True - but Murdock found that compile/fuzzing/gnrc_tcp does not compile anymore now.

brummer-simon · 2021-07-05T08:55:44Z

True - but Murdock found that compile/fuzzing/gnrc_tcp does not compile anymore now.

Should be fixed by now

miri64 · 2021-07-05T09:43:35Z

Nevertheless the test-as-root target should be run by a maintainer on a handful of platforms locally before merging ;-). If I find the time I will do :-).

miri64

Ok, now I looked at the code and found a problem 😅 .

miri64

Not sure, why my review comment did not get posted though.

fuzzing/gnrc_tcp/main.c

miri64 · 2021-07-06T13:12:50Z

Mh test works on native, but not on samr21-xpro, which isn't the case on master :-/. I'll post the relevant output with echo activated. Maybe you have an idea.

The log seems strange to me since it sends gnrc_tcp_open_passive to the target, a function that should not exist anymore. Could you perform a clean build and test again?

miri64 · 2021-07-06T13:28:35Z

I don't see how a clean build has any effect on the test script ;-).

miri64 · 2021-07-06T13:31:51Z

But did just that and same result.

miri64 · 2021-07-06T13:33:31Z

Ah wait, the output indeed differs

Seems like a timeout thats large enough on native. I'll see if I can find a board here and try to determine a suitable value

brummer-simon · 2021-07-06T15:29:15Z

@miri64 - I tested the PR on the nucleo-f401re and it worked. I added a commit increasing the accept timeout in the failing test script from 2000ms to 4000ms, I hope this is long enough for all boards with less processing power.

The failing test is the one where 1000 malformed packets are send and discarded, afterwards a valid packet is sent and used to accept the connection. In that test processing power might be the limiting factor. Could you test again?

miri64 · 2021-07-07T17:01:02Z

Nope. But 10000 works. How about, just to be on the save side to set it to 15000? Also if that is done, please squash the commits reflecting the review history.

Done

0d5db28 still needs to be squashed in the original commits.

Forgot this one. I squashed it.

Not sure why murdock is marked as failed or still doing label checks...

brummer-simon · 2021-07-08T06:59:23Z

@miri64: Should I squash it in a single commit? I splitted the PR only to help with the review.

EDIT: Since all is reviewed and green, I just squash the entire thing and merge it.

brummer-simon · 2021-07-08T08:57:03Z

@miri64 , @benpicco, since everything is green, could you press the merge button? For an unknown reason I am not able to do that anymore :(

miri64 · 2021-07-08T14:09:08Z

Where you ever? You need write permissions to hit the green button (which only maintainers have).

brummer-simon · 2021-07-08T14:11:34Z

Maybe my mind is playing a trick on me but I could swere that there was I time were I was able to press the merge button for my own PR after a successfull review. But I had never maintainer status.
