lantiq/deu driver - AES encryption very slow with strongswan

Reported by: anonymous Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: Cc:


I got a very well working net-to-net configuration with strongswan using the 3DES encryption-algorithm - the speed is up to 3MB/s. If I change this to (standard) AES-encryption the speed is very much slower - arround 20KB/s. I think it's related to the deu-driver, because with other devices I can connect to the same peer with other devices and AES encryption with normal speed.
In peer logs I see messages, that the ESP-Payload header has a wrong size, when I connect with openwrt.

Have you tried to disable lantiq-deu with rmmod? Surely you have done it but sometimes we forgot something. :$

Sorry, I forgot to mention: Yes I tried using it without the ltq-deu module and it was working with much more higher speeds (2,1 MB/s), but with a (expectable) very hight cpu load. So its quite clear, that its the deu-driver.
I also tested the encryption speed with deu-test-manager - there everything seems to be fine ....
