Description

Hi Together,

Synthom:

After server restart. While some time ago the batman-adv Gateway stop announcing it self.
This results int an emty batman-adv Gateway table (see below). Anything else seems working normal.

System Info:

batctl gwl

Dynamic bandwidth setting

In the background their is a script running which is updating every 30min the (measured - used) bandwidth.
Idea behind that: if more traffic is generated by users on this gateway then less bandwidth will be announced and new incoming clients get other gateways with higher announced bandwidth.

Bandwidth updating is done over following code (using batctl):

#!/bin/bash
gwsel_lockfile="/tmp/gwsel_lockfile"  # lockfile to allow for low bandwidth settings 

if [ -z "$1" ]; then
        echo
        echo "usage: $0 <network-interface> <update_interval [sec]> <total BW up [Mbit/sec]> <total BW down [Mbit/sec]>" 
        echo
        echo "e.g. $0 eth0 60 10 10" 
        echo
        exit
fi

while true
do
    if [ ! -e ${gwsel_lockfile} ]; then    # lockfile not present
        # Bandwidth currently used (time averaged)
        R1=$(cat "/sys/class/net/$1/statistics/rx_bytes")
        T1=$(cat "/sys/class/net/$1/statistics/tx_bytes")
        sleep "$2" 
        R2=$(cat "/sys/class/net/$1/statistics/rx_bytes")
        T2=$(cat "/sys/class/net/$1/statistics/tx_bytes")
        TkbitPS=$(echo "scale=0; ($T2 - $T1) / 1024 * 8 / $2" | bc -l)
        RkbitPS=$(echo "scale=0; ($R2 - $R1) / 1024 * 8 / $2" | bc -l)
#        echo "BW used      -- up $1: $TkbitPS kBit/s; down $1: $RkbitPS kBit/s" 

        # Remaining bandwidth available; cut-off negative values
        Tavail_kbitPS=$(echo "scale=0; if (($3 * 1024 - $TkbitPS) >0) ($3 * 1024 - $TkbitPS) else 0" | bc -l)
        Ravail_kbitPS=$(echo "scale=0; if (($4 * 1024 - $RkbitPS) >0) ($4 * 1024 - $RkbitPS) else 0" | bc -l)
#        echo "BW available -- up $1: $Tavail_kbitPS kBit/s; down $1: $Ravail_kbitPS kBit/s"

Attached, I have found some Call traces in the kernel logs which may lead into to the above effects.

Why should the device see itself in the gateway table? It also didn't do that in the past.

Attached, I have found some Call traces in the kernel logs which may lead into to the above effects.

And I don't see attachments.

Sorry, my writing is a bit unclear. I took the batctl gwl from a client not from the gateway it self. of corse I know that batman Gateway never shows it self in the Gateway List.

I selected the log file again and their is a message "Request Entity" but nothing happens.
Do I need other rights ?

5120 KiB is the limit for attachments. So you should actually be able to attach this file. But you can try to compress this file first.

And the snippet you've posted points to general memory allocation problems on the server. __netdev_alloc_skb is just not able to allocate a packet buffer when batman-adv wants to forward (fragmented) packets. This codepath requires atomic allocations - the kernel path is not able to swap, to drop caches or to do any other operation which involves blocking. And the kernel doesn't seem to be able to do that when he printed the messages

To your actually problem: It would be interesting here to get the originator packets from the server but captured on the client mesh-vpn interfaces - just to see whether the OGMs from the server really don't contain the bandwidth information. You can use wireshark to get it.

If the gateway tvlv is really missing in the OGMs of the server, is changing the gateway settings on the server fixing the problem again?

Extra info: You may want to add a bridge to batman-adv, filter the forwarding between the ports and only add the l2tp interfaces to this bridge. This avoids the manipulation operations on all originators and the associated memory overhead when adding/removing interfaces all the time. And it reduces the change for "queue is full" errors. This is also what tunneldigger does in their examples https://github.com/wlanslovenija/tunneldigger/blob/f68b7af4b3874601818c7e677e21461278df13f5/broker/scripts/bridge_functions.sh

This advise only makes sense for this special vpn tunnel setup where you have dozens of l2tp tunnel which appear and disappear all the time. Not in general for setups with wifi interfaces

Ay, I'll try a zip

Unless I missed something, the log file shows only that the system is often low on atomically allocatable memory. You are also not giving this machine a lot (269940K/309752K) - especially because this might be a machine which has to manage a lot of connections and traffic.

But nothing relevant regarding the missing(?) bandwidth information in the OGMs. Please see my earlier message about it.
