Hello, I decided to try out the md5 signature support, with a view to eventually fixing up Quagga to make use of it. As the API has changed quite a bit, I modified a simple echo client/server as a simple test. I compiled up 2.6.19-git17 and ran it under debian etch.
Unfortunately, both the client and server machines panic (actually I'm using qemu to make things easy for myself). Although my test programs might be buggy, I don't believe they should cause a panic. Has anyone got this stuff working yet? I've attached the client panic below. Both panics, the kernel .config and the source code for the test client and server can be found at: http://www.solinno.co.uk/md5sig/ Thanks, Leigh.
