MD5 TCP in Linux

[Ondrej Filip]

Hi,
we made a very interesting observation. For some reason we downgraded 
Linux kernel do 2.6.24 and MD5 signed BGP session became unstable. 
BIRD was able to establish session but later it started to send 
packets with invalid MD5 signature randomly. This caused BGP session 
drop sometimes. TSO and scatter-gather were switched off. The problem 
disappeared after upgrade to 2.6.32. So please be careful with Linux 
kernel versions.
