Bug 212381 – sys-kernel/gentoo-sources [PATCH] allow more than 200 ipsec connections with ipsec-tools

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Natanael Copa 2008-03-05 12:51:02 UTC]

In current kernel af_key users (ipsec-tools / racoon) is not able to handle more than 100-200 concurrent IPsec connections. 

The attatched patch is a backport of the upstream commits finxing this:

The patch also gives significant system performance improvement when there is large amount of ipsec connections.

Did you have to do anything special with those commits to backport them? They both seem to apply cleanly (xfrm one first) but I have not tested compiling or runtime.

I got the pathes from Timo himself and they are only a rebase to avoid noise about fuzz/diff. He says the raw diffs should work as-is against .24.

ok, compile tested and queued for next release
