This patch cleared up a lot of TAHI failures for us:

  http://sources.redhat.com/ml/ecos-patches/2002-08/msg00078.html

AFAICT, all of our patches are in the public CVS.

From a report on the test run:

  ============================================
   IPv6 Stateless Address Autoconfiguration
  ============================================

  Originally failed tests should now pass.  Reason: new
  ipv6_routing_thread does not emit unexpected packets.

  Exempt tests: #21-#30, #54-#56
  Reason:  Not applicable: Infrastructure missing, no 'ifconfig',
  'route' or 'setkey' utilities, so even in manual mode, boot-time
  config is not possible in eCos.

Thanks for checking that.

Ah, I didn't remember/know there were exemptions. At a guess the 
autoconfiguration stuff must be one of those, but I'm sure Matthew will 
say if not.

Re: [ECOS] global addressing in ecos

[matthew de veza]

We've applied the patch and re-run all the tests for the stateless address 
autoconfiguration, and we also exempted the tests indicated below (21-30, 
54-56). The tests that passed are those that wait for the DAD to fail (it 
wants the target to basically not send any echo reply/packet) and all the 
other tests failed. These are basically the tests that wants the target to 
echo-reply. We believe that the cause is that the global address cannot be 
set; it would seem that the target does not respond to DAD which are sent 
using a multicast address.

This seems to lead me into thinking that the entire set of stateless 
autoconfiguration is exempted. Can anyone please verify? Or on another train 
of thought, I would like to ask if anyone would know why we cannot set the 
global address, and why the target does not seem to respond to multicast 
queries.

I would like to ask Mr. Hamilton if you could share your test results for 
the ecos target tested by TAHI if this is not confidential so we could more 
or less compare our test results with yours.


Thank you.
Matt

Re: [ECOS] global addressing in ecos

[matthew de veza]

thanks for the reply, we've tried using the tcpdump to analyze the packets 
being sent out, and it seems as if the target cannot "read" the global 
prefix being sent to it. a lot of the tests fail with the "NUT address not 
configured" error.

only a small percentage of the tests pass, and these mostly involve 
link-local addressing only. a lot of the tests would fail if a multicast 
and/or global address is involved.

Re: [ECOS] global addressing in ecos

[matthew de veza]

Thanks for the reply. Actually only a small percentage out of the entire set 
of tests for Stateless Address Autoconfiguration passed, and these mainly 
are involved with link-local addresses only. There are instances wherein the 
NUT does not reply to tester node queries, and a lot of the Duplicate 
Address Detection tests failed.

We used the TCP Dump to analyze the packets being sent in the network, but 
the ecos target does not seem to recognize the global prefix being sent to 
it, or sometimes the target does not give an echo-reply. A lot of the tests 
would fail with a "NUT Address not configured" error.

Would anyone know why this is the case? Or can anyone tell us what we can do 
to enable the target to "read" the global add. prefix to be able to set the 
global address? Or does anyone know if this can actually be done?

Thank you.

Actually I thought they were contractually obliged to complete it and get 
the TAHI testsuite running. If so, they should have made some fixes to 
fulfil the contract. Perhaps they didn't contribute back the patches?

Anyone from Red Hat out there?

I'm afraid you're somewhat on your own here.  Red Hat pulled
the plug on the eCos project (dropped most of the developers)
before the IPv6 project was really complete, so there may
be many things that aren't quite working.

What have you tried?  What works, what doesn't?  Have you
tried to watch the traffic, e.g. using a network analyzer?

[ECOS] global addressing in ecos

[matthew de veza]

we've been testing an ecos target with the tahi test suite and the tests 
which involves autoconfiguration of global addresses seem to all be 
unsuccessful. i would really like to find out if the global address 
autoconfiguration feature/stateless address autoconfiguration feature which 
was ported from freebsd to ecos has been fully ported and is robust and 
functional. can anyone please help me?

thank you.
