#19617 duplicate Fedora 32 support Panos Kavalagios
Description

Attempt to upgrade from Fedora 31 to Fedora 32 is blocked by VirtualBox lacking support for 32:


Problem: conflicting requests

  • nothing provides module(platform:f31) needed by module gimp:2.10:3120191106095052:f636be4b-0.x86_64

Error:

Problem: package VirtualBox-6.1-6.1.8_137981_fedora31-1.x86_64 requires python(abi) = 3.7, but none of the providers can be installed

  • python3-3.7.7-1.fc31.x86_64 does not belong to a distupgrade repository
  • problem with installed package VirtualBox-6.1-6.1.8_137981_fedora31-1.x86_64

#19615 invalid Linux - hostonlif ipconfig modifies system default route cssolomonides
Description

Hello,

creating a hostonlyif and assigning an IP to it via vboxmanage hostonlyif ipconfig vboxnet0 --ip 192.168.56.1 results in mangling the host system routing, giving maximum priority to the hostonly interface for default route.

$ vboxmanage --version
6.1.6_Ubuntur137129

$ ip route ls
default via 192.168.10.1 dev wlan0 proto dhcp src 192.168.10.4 metric 303 mtu 1500

$ vboxmanage hostonlyif create
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Interface 'vboxnet0' was successfully created

$ ip route ls
default via 192.168.10.1 dev wlan0 proto dhcp src 192.168.10.4 metric 303 mtu 1500

$ vboxmanage hostonlyif ipconfig vboxnet0 --ip 192.168.56.1

$ ip route ls
default via 192.168.56.1 dev vboxnet0 src 192.168.56.1 metric 212
default via 192.168.10.1 dev wlan0 proto dhcp src 192.168.10.4 metric 303 mtu 1500

As this behavior mangles system network connectivity, it would be expected that the default route created by the hostif network has lower priority compared to existing ones.

#19610 fixed Null pointer dereference in vmsvgaR3PortReportMonitorPositions when using VboxVGA graphics device => fixed in svn/6.1.x x>10 gombara abacabadabacaba
Description

I'm using VirtualBox 6.1.8 with 64-bit Debian both as a host and as a guest OS.

Under specific conditions, VirtualBox crashes during guest OS boot. I found the following necessary conditions for the crash to occur:

  • Graphics device: VboxVGA.
  • Guest additions version 6.1.8 must be installed in the guest. With earlier versions (such as 6.1.6), the bug doesn't reproduce.

Here is a stack trace of the crash:

During the execution of vmsvgaR3PortReportMonitorPositions function, the value of pSVGAState variable is a null pointer. The crash happens when the pointer is dereferenced.
