TProxy version 2.0.6 has been released for Linux 2.4.33, 2.4.34, 2.6.16, 
2.6.17, and 2.6.18, 2.6.19, and 2.6.20-rc3. (I hope the 2.6.20-rc3 patches 
will work for final 2.6.20 kernels, too). Because of the severity of 
problems discovered all TProxy users are advised to upgrade.

This release fixes multiple serious problems discovered since the 2.0.5 

* an SMP race condition possibly leading to memory corruption in the 
nat_delete patch (reported and fixed by torinet.co.kr user wckwon)

Linux 2.6 specific bugs:
* a serious problem related to the TCP time-wait socket unassign callback 
leading to referencing invalid memory addresses

Linux 2.4 specific problems fixed:
* a possible kernel hang (deadlock) if the NAT reservations and NAT delete 
patches are both applied
* an interaction between the iptables TPROXY and REJECT rule which could 
lead to kernel oopses if UDP packets have been first TPROXY-ed and later
