Fwd: memory leak

[Florian Schoedel]

Hi, 
I've observed this strange behaviour for a while in my test environment. It 
looks like that all problems gone away when I switch to "hub-mode" instead 
of switch mode. 
Does tinc still work properly in switch mode when I transport vlan tagged 
traffic within that tunnel? In my environment the side, which is receiving 
arp requests from the wired interface, is running out of memory. The other 
side, which receivces the arp requests through the tunnel doesn't run out of 
memory. 

Best regards


Florian

Subject: memory leak

Hi, 

I am running tinc on alpine linux 2.7.8 in 2 seperate environments. The 
first environment is running for about a month without any problems.
The second environment causes some trouble. It looks like a memory leak on 
the client side. 

tincd.conf:

ConnectTo=ServerHost
Device=/dev/net/tun
Mode=switch
Name=ClientHost
PMTUDiscovery = yes
DeviceType=tap
PriorityInheritance = yes
Compression=10

hosts/ServerHost


Address=XXXX
PMTUDiscovery = yes
PriorityInheritance = yes

Linux Kernel 3.10.40-0-grsec #1-Alpine SMP Wed May 14 07:59:37 UTC 2014 
x86_64 Linux

apk info tinc

It doesn't matter if I bypass-security or disable / enable compression. 




Can anybody confirm, that tinc is running on alpine linux with this software 
versions?

Thanks a lot


Florian
