5a82362ad0 slirp: Strictly associate DHCP/BOOTP and TFTP with virtual host
Instead of accepting every DHCP/BOOTP and TFTP packet, only invoke the
built-in servers if the target is the virtual host.

12b513d837 slirp: Fix restricted mode
This aligns the code to what the documentation claims: Allow everything
but requests that would have to be routed outside of the virtual LAN.

So we need to drop the unneeded IP-level filter, allow TFTP requests,
and add the missing protocol-level filter to ICMP.

There is no need to have a second set of integral types.
Replace them by the standard types from stdint.h.

97df1ee542 slirp: Remove UDP protocol emulation (talk, cuseeme)
The UDP emulation code for talk has been commented out since the
beginning of time, and unless someone who runs CU-SeeMe on qemu with
user-mode networking can vouch that the special magic (a) is necessary
and (b) works, let's get rid of the code.

460fec67ee slirp: Factor out internal state structure
The essence of this patch is to stuff (almost) all global variables of
the slirp stack into the structure Slirp. In this step, we still keep
the structure as global variable, directly accessible by the whole
stack. Changes to the external interface of slirp will be applied in
the following patches.

0d62c4cfe2 slirp: Drop dead code
After all its years inside the qemu tree, there is no point in keeping
the dead code paths of slirp. This patch is a first round of removing
usually commented out code parts. More cleanups need to follow (and
maybe finally a proper reindention).

a13a4126c8 slirp: Rework internal configuration
The user mode IP stack is currently only minimally configurable /wrt to
its virtual IP addresses. This is unfortunate if some guest has a fixed
idea of which IP addresses to use.

Therefore this patch prepares the stack for fully configurable IP
addresses and masks. The user interface and default addresses remain
untouched in this step, they will be enhanced in the following patch.

2f5f899631 Remove the advertising clause from the slirp license
According to the FSF, the 4-clause BSD license, which slirp is covered under,
is not compatible with the GPL or LGPL[1].

[1] http://www.fsf.org/licensing/licenses/index_html#GPLIncompatibleLicenses

There are three declared copyright holders in slirp that use the 4-clause
BSD license, the Regents of UC Berkley, Danny Gasparovski, and Kelly Price.
Below are the appropriate permissions to remove the advertise clause from slirp
from each party.

Special thanks go to Richard Fontana from Red Hat for contacting all of the
necessary authors to resolve this issue!

Regents of UC Berkley:
From ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

July 22, 1999

To All Licensees, Distributors of Any Version of BSD:

As you know, certain of the Berkeley Software Distribution ("BSD") source
code files require that further distributions of products containing all or
portions of the software, acknowledge within their advertising materials
that such products contain software developed by UC Berkeley and its
contributors.

Specifically, the provision reads:

"     * 3. All advertising materials mentioning features or use of this software
      *    must display the following acknowledgement:
      *    This product includes software developed by the University of
      *    California, Berkeley and its contributors."

Effective immediately, licensees and distributors are no longer required to
include the acknowledgement within advertising materials.  Accordingly, the
foregoing paragraph of those BSD Unix files containing it is hereby deleted
in its entirety.

Hi Richard,

I have no objection to having Slirp code in QEMU be licensed under the
3-clause BSD license.

Thanks for taking the effort to consult me about this.


Dan ...

To: "Richard Fontana" <rfontana@redhat.com>
Subject: Re: Slirp license

Thanks for contacting me, Richard.  I'm glad you were able to find
Dan, as I've been "keeping the light on" for Slirp.  I have no use for
it now, and I have little time for it (now holding onto Keenspot's
Comic Genesis and having a regular US state government position). If
Dan would like to return to the project, I'd love to give it back to
him.

As for copyright, I don't own all of it.  Dan does, so I will defer to
him.  Any of my patches I will gladly license to the 3-part BSD
license.  My interest in re-licensing was because we didn't have ready
info to contact Dan.  If Dan would like to port Slirp back out of
QEMU, a lot of us 64-bit users would be grateful.

Feel free to share this email address with Dan.  I will be glad to
effect a transfer of the project to him and Mr. Bellard of the QEMU
project.
