[Cerowrt-devel] potentially dropping mesh networking from cerowrt rc8 [#201]

This is the second of a series of emails discussing things that may be
dropped from the next release of cerowrt, and is intended to open the
The goal is to find better ways to focus on fixing bufferbloat.
While I personally find babel very useful, as well as AHCP, convincing
anyone that these two bleeding edge technologies are worthwhile on
places like the homenet mailing list is an incredible struggle. The
consensus there appears to be leaning towards ospf, not that anyone on
that list has bothered to test that, either. We have had the ability
to use ospf in the system since day one as an optional package.
Routing, actually, is not needed in simple setups.
1) The AHCP package in openwrt keeps breaking. It broke of the late
rc7-smoketest6-ish series, and so far as I know, hasn't been fixed.
1a) The gui interface, even when the package was working, is equally
2) Firewalling remains REALLY problematic with both babel and AHCP.
More often than not, you end up with stuff
that doesn't work.
3) Packet loss as a metric appears to not be a good metric anymore.
4) As much as I enjoy mesh networking, the few people that have tried
to set it up independently that I know of, have all failed.
5) As pointed out during a test in brussels, cerowrt itself has become
too complex even for someone familiar with openwrt to deal with it.
So with no real users of these subsystems in the field, these two
packages can be safely dropped.
There were some positive benefits to being able to test ad-hoc mode,
having the interfaces available at all times, etc, but deleting the
extra interfaces and firewall complexity would help.
While I believe that a pure mesh environment works a LOT better than a
pure 'as we know networking today' environment, however, the attempt
of merging the 'best of' the two, seems to be worse, than either.
This eliminates having to fix bugs #252, #110, #112, #201, and I've
never got around to mentioning how much I was hoping for dhcp/ahcp
