[Qemu-devel] [PATCH 0/1] slirp: Add domainname option to slirp's DHCP server

[Benjamin Drung <benjamin.drung@profitbricks.com>]

Hi,

The DHCP server in QEMU does neither support specifying a domainname nor
a classless static route option [1]. I implemented the former (which was easy),
but I am not sure if and how to implement the classless static route option.

An example classless static route option configured in ISC's DHCP server look
like

  option rfc3442-classless-static-routes 24, 10, 0, 2, 10, 0, 2, 2, 16, 192, 168, 10, 0, 2, 2;

This translates to the routes:

10.0.2.0/24 via 10.0.2.2
192.168.0.0/16 via 10.0.2.2

Should the command line option just behave like the ISC's DHCP server and
allow specifying the byte stream passed to the client? E.g.

  -net staticroutes=24.10.0.2.10.0.2.2.16.192.168.10.0.2.2

Or should the command line option be simpler, but how should it be specified
then? Maybe

  -net staticroute=10.0.2.0/24via10.0.2.2,staticroute=192.168.0.0/16via10.0.2.2

I am open for your ideas.
