[B.A.T.M.A.N.] [PATCH] batman-adv: unset the TT_CLIENT_PENDING flag if the new local entry already exists
by Antonio Quartulli 04 Apr '12

04 Apr '12

When trying to add a new tt_local_entry, if such entry already exists, we have to ensure that the TT_CLIENT_PENDING flag is not set, otherwise the entry will be deleted soon.

Hi! After upgrading to latest batman version on openwt batman stopped adding ethernet or bridge interfaces at start... it add only wireless interfaces I am using backfire for the core and trunk for packages the problem is related to that?

Hi David, here comes the second set of patches I'd like to see pulled into net-next-2.6/3.4. It mostly contains code cleanups, some code refactoring work and a minor fix.

Ok in this email my proposal patch. I've to sleep 4s if you have an ap + adhoc vifs. [ "$(echo $interface | awk '$0 ~ /^wlan[0-9]*/')" ] && sleep 4s For convenience I sleep only if an wlan was triggered. If you have only one interface in adhoc mode per radio 3 seconds are enought. bye ---------- Messaggio inoltrato ---------- Da: Marek Lindner <lindner_marek(a)yahoo.de> Date: 11 febbraio 2012 11:08 Oggetto: Re: /lib/batman-adv/config.sh A: Filippo Sallemi <tonyputi(a)gmail.com> On Friday, February 10, 2012 01:21:21 you wrote: > > Yeah - looks good. > > I still don't get why we don't need to wait 3/5 seconds anymore.

Ok - I left the "sleep 3s" in the file. I applied your config_bat/bat_config as well as the forgotten ap_isolation config fix. Since the for loop does not fix the wait problem why do you wish to change it? I am referring to your suggested change: # Load network config here just in case! config_load network for iface in $interfaces; do # copy iface into ifname local ifname=$iface [ -f "/sys/class/net/$ifname/batman_adv/mesh_iface" ] || { # if ifname was not found try to find it via uci config config_get ifname $iface ifname [ -f "/sys/class/net/$ifname/batman_adv/mesh_iface" ] || continue } [ "$ifname" = "$interface" ] && echo $mesh > /sys/class/net/$ifname/batman_adv/mesh_iface done bat_add_interface() and bat_del_interface() have the same loop but we only change one ? The only difference I can see is another added variable and not calling "uci -q -P/var/state get network.$iface.ifname". Why ? Cheers, Marek -- Filippo Sallemi

[B.A.T.M.A.N.] [PATCH] batman-adv: fix wrong dhcp option list browsing
by Antonio Quartulli 28 Feb '12

28 Feb '12

In is_type_dhcprequest(), while parsing a DHCP message, if the entry we found in the option list is neither a padding nor the dhcp-type, we have to ignore it and jump as many bytes as its length + 1. The "+ 1" byte is given by the subtype field itself that has to be jumped too.
