[B.A.T.M.A.N.] batman-adv and/or batmand porting effort to FreeBSD
by Mahdi Mokhtari
Hi,
After some time of playing with the B.A.T.M.A.N protocol and
net-interface on OpenWRT and Debian I was thinking to use it with
the servers I use everyday (and maybe on routers/appliances I have
nanoBSD on).
So I started an effort...
(As a background) I already ported some applications to FreeBSD [and I'm
maintaining them] and
also I did work already on the Linux emulation layer of FreeBSD (FreeBSD
has a Linux syscall-emulation and Linux-KPI layers).
So my approach (as naturally I didn't expect the build of batman-adv.ko
to be successful as is),
was based on the approach that we [at FreeBSD] did to port Linux's
drm... <https://github.com/FreeBSDDesktop/kms-drm>
I ended up in adding some header-files to FreeBSD Linux-KPI (like
average.h, percpu.h, ...).
Now I'm at a state that Netlink blocks me and I'm to determine next step :-)
[Which I don't assume it being trivial with my current approach]
So I'd like to ask:
1- Is it better approach to "rewrite" batman-adv.ko [at least
Netlink-ish (let's call "Linuxism") parts] than what I'm doing now?
2- Any other efforts are being done out there?
3- is batmand deprecated [So I should mainly focus on batman-adv.ko]?
4- any other comments do you have? :D
P.S. sorry if I'm not really good at starting conversation from scratch
and out-of-nowhere :D
but I hope by continuing the collaboration we can have better (more
enriched) FreeBSD and better (as in more portable) B.A.T.M.A.N :-)

[B.A.T.M.A.N.] [PATCH v5 0/7] B.A.T.M.A.N. V - fallback to tp meter estimation if throughput otherwise not available
by Marek Lindner
Under normal circumstances B.A.T.M.A.N. V retrieves the neighbor
throughput values to populate its metric tables from the various
drivers such as WiFi throughput tables and Ethernet throughput..
Whenever the interface drivers do not export link throughput
information manual overrides become necessary. To further
automate and thus better support these setups, ELP may call the
batman-adv throughput meter to schedule a throughput estimation
to be used to populate the metric table.
v5:
* fix tp_vars refcount on queue_work() failure
* squash batadv_tp_start_work() into batadv_tp_start()
v4:
* read tp measurement result only once
v3:
* fix ELP tp meter result computation
* use batadv_has_timed_out() instead of custom implementation
* set ELP tp meter test duration to 1000ms in patch #6
* add comment explaining periodic scheduling
v2:
* added sysfs attribute to configure tp meter test duration
* fixed null pointer dereference in TP meter packet sending routine
* fixed storing the measured throughput in the correct variable
* checkpatch/kerneldoc/sparse/smatch cleanup
Antonio Quartulli (3):
batman-adv: tp_meter - prevent concurrent tp_meter sessions by using
workqueue
batman-adv: tp_meter - don't check for existing session
batman-adv: tp_meter - add option to perform one-hop test
Marek Lindner (4):
batman-adv: tp_meter - allow up to 10 queued sessions
batman-adv: tp_meter - add caller distinction
batman-adv: ELP - use tp meter to estimate the throughput if otherwise
not available
batman-adv: ELP - add throughput meter test duration attribute

How to give stable MAC address to batman-adv device?
by batman.mexon＠spamgourmet.com
Hi,
I'm trying to use batman-adv to fix wifi signal problems with a few
Raspberry Pis. So far it's more-or-less working. I'm using dnsmasq on
the main gateway node to serve IP addresses over DHCP.
One problem I have is that the bat0 device has a different MAC address
each time it starts. My Raspbery Pis reboot each day on a cron job and
each time they get a new MAC. This causes dnsmasq to give them a new IP
address. This causes problems talking to other nodes with outdated DNS
caches, as well as being irritating when I try to use ssh and it thinks
the nodes are "impersonating" each other.
Is there a way to force batman-adv to use a stable MAC address?
Thanks,
Matthew Exon
