[B.A.T.M.A.N.] [PATCH] Make batman timer functions thread safe

by Sven Eckelmann

The calculation inside of update_internal_clock aren't atomic and can lead to bogus time informations when many threads calling get_time_msec64 or get_time_msec.

[B.A.T.M.A.N.] 0.3.1 rv1152 - some test results

by Chris W.

Hello, thought I'd just let you know what I experienced when testing rv1152 on an outdoor network with atheroses and broadcoms, olsr in parallel. Interfaces are started with ifconfig eth1:1 10.4.2.29 netmask 255.255.0.0 broadcast 10.4.255.255 The batman test area looks something like this: http://preveli.gr/mesh/bat-228-2b.gif -1- gateway: a gw is started with batmand -s 10.4.2.50 -g 2mbit/256kbit eth1:1 the client 2.29 with batmand -s 10.4.2.50 -a 10.2.29.0/24 -r 2 ath0:1 When pinging the gateway through the client node or when accessing the internet through the node it logs Nov 26 22:52:04 (none) kern.err batmand[1287]: Error - got packet from unknown client: 10.4.2.29 (virtual ip 10.2.29.136) The tunnel itself is flickering, this happens with -r1,2,3 and -p client log: Gateway client - gateway (10.4.2.2) says: IP (169.254.0.1) is expired Deleting default route via gate0 (table 68) Adding default route to 10.4.2.2 (gw_flags: 40, tq: 178, gw_product: 0) Error - couldn't create tunnel: old tunnel is still active Adding default route to 10.4.2.2 (gw_flags: 40, tq: 179, gw_product: 0) Gateway client - got IP (169.254.0.1) from gateway: 10.4.2.2 Adding default route via gate0 (table 68) Gateway client - gateway (10.4.2.2) says: IP (169.254.0.1) is expired Deleting default route via gate0 (table 68) Adding default route to 10.4.2.2 (gw_flags: 40, tq: 181, gw_product: 0) Gateway client - got IP (169.254.0.1) from gateway: 10.4.2.2 Adding default route via gate0 (table 68) gateway log: Gateway - assigned 169.254.0.1 to client: 10.4.2.29 Gateway - assigned 169.254.0.1 to client: 10.4.2.29 Gateway - assigned 169.254.0.1 to client: 10.4.2.29 -?- What is batgat for, does it disannounce a gateway which in fact is down e.g due to dsl-failure ? -2- together with olsrd.

[B.A.T.M.A.N.] [PATCH] Reduce verbosity of make

by Sven Eckelmann

Make's normal output makes it hard to distinguish between warnings and commands, but `make -s` will completely hide information about what is currently done and irritate the user. A good compromise is linux way of printing the type of build command and the output filename of each target. The normal behaviour can be restored by running `make V=99`.

[B.A.T.M.A.N.] [PATCH] Don't create different definitions of variables from header

by Sven Eckelmann

Declaration of variables in header files must be marked extern or they will create new definition in all files which include it. This could create collisions on different architectures or by using different linkers. A different effect is the misfeature of the program when different files access these variable and think they would use the same variable in memory.

[B.A.T.M.A.N.] BATMAN routing (via gate0)

by Derek C

Hi [yet] again! Can someone detail how BATMAN routes? For example if I have nodes with IPs like: 5.255.0.1 5.255.0.2 5.255.0.3 etc I see that BATMAN makes a tunnel to the gateway and then routes traffic via the 169.254 gate0 subnet Does this mean that all outgoing from the node should be NATed? or is it possible for the upstream node(s) to ping the node via its true IP address (5.255.XXX.XXX) ? thanks again, Derek -- Derek C

by Outback Dingo

Anyone know if there exists a luci, ffluci, or freifunk kamikaze atheros capable freifunk-batman capable package or is there just no support for atheros, mips and luci with bmxd on the mesh mesh??? ive seen hints at potentially prior work but i would swear someone here uses is on a freifunk mesh ? question is is there an atheros/mips based for Atheros ahdemo or NS2 devices???

[B.A.T.M.A.N.] gateX interfaces

by Derek C

Hi, Currently I'm constantly killing batmand and starting it up again (different debugging levels, etc). Sometimes I end up with a 2nd gate tunnel (so I'd have a gate0 and a gate1). I understand (guess?) that it's because I do kill -9 and don't give batmand a chance to clean up. Normally is it true that there would only ever be one tunnel (gate0) ? when multiple nodes are deployed is this still always the case? thanks, Derek -- Derek C
