Public bug reported:

Building QEMU with GLib newer than 2.58.3 corrupts tap networking on macOS hosts.
Tap device was provided by Tun/Tap kernel extension installed from brew:
  brew install tuntap

Checked revisions:
  553032d (v5.2.0)
  6d40ce0 (v6.0.0-rc1)

Host:
 MacBook Pro (Retina, 15-inch, Mid 2015)
 macOS Catalina 10.15.6 (19G2021)

Guest:
  Linux Ubuntu 4.4.0-206-generic x86_64
  Also tested macOS Catalina 10.15.7 as a guest, the behaviour is the same.

QEMU command line:

qemu-system-x86_64 \
  -drive file=hdd.qcow2,if=virtio,format=qcow2 \
  -m 3G \
  -nic tap,script=tap-up.sh

tap-up.sh:

 #!/bin/sh

 TAPDEV="$1"
 BRIDGEDEV="bridge0"

 ifconfig "$BRIDGEDEV" addm "$TAPDEV"

Enabling/disabling Hypervisor.Framework acceleration (`-accel hvf`) has
no effect.

How to reproduce:
  1. Build & install GLib > 2.58.3 (tested 2.60.7, 2.60.7)
  2. Build qemu-system-x86_64 with GLib > 2.58.3
  3. Boot any guest any guest with tap networking enabled
  4. See that the external network is inaccessible

Hotfix:
  1. Build & install GLib 2.58.3
  2. Build qemu-system-x86_64 with GLib 2.58.3
  3. Boot any guest with tap networking enabled
  4. See that the external network is accessible, everything is working as expected

The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting the bug state to "Incomplete" now.

If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".

If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:

1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:

    https://gitlab.com/qemu-project/qemu/-/issues

and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.

2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).

Thank you and sorry for the inconvenience.
