Bug 85904 – cisco-vpnclient-3des needs patch for working with kernel >=2.6.10

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Benjamin Greiner 2005-03-19 07:45:10 UTC]

There is a coplete system hang, when I try to start the Cisco vpn client with kernel 2.6.10 (gentoo-r6). 

This is because the kernel developers changed the API somehow in net/core/dev.c wher skb_checksum_helper requires different pointers than in older kernel versions.

There is a patch around the net, which solves the problem. vpnclient connect works fine, if applied.


Reproducible: Always
Steps to Reproduce:
1. # uname -r
2.6.10-gentoo-r6
2. # emerge =cisco-vpnclient-3des-4.6.00.0045-r1
3. # /etc/init.d/vpnclient start
4. $ vpnclient connect yourprofile
Actual Results:  
total system freeze on call

Expected Results:  
working vpnclient

Strange.... I have no problems on my 5 machines with 2.6.10 and 2.6.11... I'll look into this, though and let you know.

Your're right, The system doesn't freeze on my laptop even without the patch. There is only the compiler warning.

However it definitively does on my Desktop system. With the patch everything works ok and the compiler warning doesn't appear anymore.

Well, I'll start looking into it.  If the patch doesn't seem to break anything, then I'll apply it.

Give me a couple days to get things under control with the 2005.0 release and I should have plenty of time to work on it.

Can you see if this is still an issue with 4.5.03.0190?

If it is, then please REOPEN this bug.
