[B.A.T.M.A.N.] List policy for none subscribers
by Andrew Lunn
Hi folks
Yesterday evening i sent an email to Greg KH about getting batman into
mainline via staging. I CCed the list. Since i used an account which is
not subscribed, i got a bounce:
You are not allowed to post to this mailing list, and your message
has been automatically rejected. If you think that your messages
are being rejected in error, contact the mailing list owner at
b.a.t.m.a.n-owner(a)lists.open-mesh.net.
This is contrary to what the wiki says:
http://open-mesh.org/wiki/MailingList
You can subscribe to our Mailing List here. You can also send an
E-Mail without subscription to b.a.t.m.a.n@…, but note that this
message will have to be accepted manually (and this can take some
time).
Greg KH reply also bounced, and he was not so happy about that.
If we want to receive comments from the kernel experts, we are
probably going to need an open list.
I can think of two options:
1) Make the batman list open for none subscribers to post to.
2) Create a batman-adv list which is open and we use that for all
discussion about kernel work.
As a side issue, i'm not sure batman-adv is the right name for
mainline. In the context of the batman project, it makes sense, but
from the perspective of mainline, this is the first version of batman,
and maybe we cannot justify the advanced.

[B.A.T.M.A.N.] [patch] adding subgraph-feature to vis-output in dot-file-format
by Linus Lüssing
Pfeh... long night again, but here you go. With this patch,
batman-adv now supports the subgraphing-feature of the
dot-file-format. The vis-output can then be parsed with
"fdp -Tsvg -Gcharset=utf8 /proc/net/batman-adv/vis > test.svg"
for example.
Interfaces belonging to one BATMAN-node can be found
inside a box, the primary interface of a BATMAN-node is
double-circled. The output also got more detailed, in that
connections between nodes are being displayed with the exact
mac address of the used interface instead of replacing one end
with the primary interface's mac (see [0] for the problems I had
posted before).
Cheers, Linus
PS: Please check if I got that kmalloc stuff right.
PPS: I had to introduce a src-field in the vis-packet-struct,
therefore the compatibility version had to be increased as well.

Re: [B.A.T.M.A.N.] Getting batman into staging
by Andrew Lunn
Hi Greg
CC: to the batman list should now work for you. Your email address has
been listed as O.K. to accept. There is an ongoing discussion about an
open list and fighting SPAM etc.
> But first off, what is keeping this code from being added to the "main"
> portion of the kernel tree? Have you submitted it for inclusion there

I'm reasonably new to the project so don't know the history too
well. I get the impression the code has not been sent to lkml or
linux-net list. There seems to be a perception within the developers
that getting code into mainline is difficult, so why bother when it
has been going O.K. out of mainline. I think you saying it could go
into staging right now has taken quite a few people by surprise.
Is staging the right way to do this? Is posting to say linux-net
better for this sort of code?
> Sound good? If so, send me some patches!
Assuming we do go via staging, do you want one jumbo patch, 6500 lines
of code, or should i break it up into smaller chunks?
Thanks
Andrew

If it is "self-contained" then we can add it to the staging tree.

Heh, bad example, that code is getting ripped out for the 2.6.32 release
as there has been no support from the developers to get this code into
mergable shape :)

Good.
But first off, what is keeping this code from being added to the "main"
portion of the kernel tree? Have you submitted it for inclusion there
already? If so, what was the response? If not, why not?

Hm, based on the above, right now :)

Yes, it can go in right now, with that TODO file, and we, and you, can
work on it there.
Sound good? If so, send me some patches!

[B.A.T.M.A.N.] [batman-adv] Use prinkt instead of debug_log
by Andrew Lunn
If batman is to get into mainline, the use of debug_log will need to
be removed. This is a first step in this direction. It replaces
debug_log calls for CRITICAL, WARNING and NOTICE with printk calls.
It tries to consistently prefix all such output with "batman:" making
it easier to find such output mixed in with other kernel messages.
LOG_TYPE_BATMAN and LOG_TYPE_ROUTES has not been changed.
