[PATCH 05/10] slirp: update for iOS resolv fix
Posted by Joelle van Dyne 5 years, 2 months ago 
From: osy <osy86@users.noreply.github.com>

We cannot access /etc/resolv.conf on iOS so libslirp is modified to use
libresolv instead.

NAck.

You can not take over the SLiRP project submodule that way.

I suggest getting your SLiRP changes merged with mainstream
instead, see:
https://gitlab.freedesktop.org/slirp/libslirp#contributing

Btw, I also noticed the coroutine library submodule proposed in this series
is a fork from the original library. Not sure what the upstream status is
and whether this is fine.

I am being wary because the series is not posted as RFC.

But from the cover it looks like a RFC series:

* slirp updated to support DNS resolving using libresolv; a separate
   patch will be submitted to the project. To allow for builds to
   succeed, the .gitmodule is temporarily changed. We're not entirely
   sure how cross-project patches should be handled here.

Sorry, I was not aware of the rules for RFC. I will remove this one from
the v2 patch set. If and when the libslirp changes are in, what are the
procedures for sending the QEMU side changes?
