[IPv6 TAHI] Section 1: RFC 2460 - IPv6 Specification #1716

Open nashif opened 7 years ago

nashif commented 7 years ago

Reported by ethan gao:

The TAHI is used to validate the implementation of Zephyr IPv6 stack, and now all the tests were ran within QEMU using echo_server as the Zephyr NUT peer, please refer to setup guideline here(https://wiki.zephyrproject.org/view/Zephyr_IPv6_testing_with_TAHI) if necessary.

[The gap/issue]

  1. The Pass/Total of Zephyr is 13/54, but the reference of Linux is 100% pass rate.

  2. QEMU crashes at running test "index 9 Part B: Unexpected Next Header in IPv6 Header"， as follows: tahi@tahi:~/workspace/Self_Test_5-0-0/spec.p2$ sudo ./IP_NH_Unexpected.seq -pkt ./IP_NH_Unexpected.def -log 9.html -ti "Part B: Unexpected Next Header in IPv6 Header" Calling POSIX::tmpnam() is deprecated at /usr/local/share/perl/5.22.2/V6evalTool.pm line 1220. Start Capturing Packets (Link0) Send Echo Request with Unexpected Next Header Cannot receive ICMP Error message NG --- Cleanup NUT Send Neighbor Advertisement (Link-Local Address with Different Link-layer Address) Send Echo Request Wait for transit target Neighbor Cache Entry to INCOMPLETE/NONCE (10 sec.) Stop Capturing Packets (Link0)

It was not clear from the bug description whether you are using master or not branch. Anyway, there is this patch in net called "net: core: Fix IPv6 extra header options handling" that should / might fix the crash issue you are seeing. This patch is not yet in master but is found in net.

ethan gao , did you see jukka]'s comment above? Can you provide the clarification needed on whether it was found on master or the net branch?

The crash can be resolved now and it's not the key point of this ticket, the critical is the run/pass rate.

Removing the 1.9 release designation -- we will ensure TAHI support for this RFC in the later releases
