[Qemu-devel] [PATCH 0/4] slirp: Fixes for restricted mode and more

[Jan Kiszka <jan.kiszka@siemens.com>]

For isolating slirp-attached guests from the world, QEMU provides the
restricted mode. However, its implementation suffers from bugs that
makes it practically unusable. Most probablematic is broken DHCP.

This series fixes that and canonicalizes the corresponding command line
switch. It also cleans up the addressing of the built-in DHCP and TFTP
server and drops the pointless m_freem wrapper.

Please review/merge.
