Hi all,
Small update from my side: I'm currently trying to determine the exact
patch or patch set that is responsible for the described problem.
Earlier I assumed a change in `[...]/sys/netinet/if_ether.c` could be
responsible, but from my testing this is not the case (see below).
I compiled a bsd.IP22 kernel for every change date for
`[...]/sys/netinet/if_ether.c` between 5.5 and 5.6 after using `cvs
update -d-R -D <DATE>` (I started with the content of [1]). As I'm
totally new to CVS, please let me know if I made a mistake with that
command. My intention was to update my sandbox with all changes up to a
specific date.
[1]: http://ftp.vim.org/OpenBSD/5.5/sys.tar.gz
I then booted all the resulting kernels with the Indy and so could at
least find out that the assumed responsible change must have happened
between:
"Mon Jun 16 19:47:21 2014 UTC"
...and:
"Sat Jul 12 14:26:00 2014 UTC"
...because the kernel from June still works, but the kernel from July
cannot successfully complete the reverse ARP.
I ruled out that a change in `[...]/sys/netinet/if_ether.c` alone could
be responsible, because when reverting the change to this file from "Sat
Jul 12 14:26:00 2014 UTC" and compiling the bsd.IP22 kernel with this
repo state it's still not working properly.
Do you have any suggestions on how to proceed, because there were still
a lot of changes between those two dates. Even when removing changes to
other architectures, the remaining patches are still about 1 MiB.
If time allows I'll try to do some manual bisecting with the dates of
the remaining commits this weekend and try out the resulting IP22
kernels on my Indy. To be sure the issue still exists, I'll also try the
final OpenBSD 6.0 kernel for IP22.
Bye
Frank
