RELEASE NOTES FOR GUESTFS TOOLS 1.50

These are the release notes for guestfs tools stable release 1.50. This describes the
major changes since 1.48.

Guestfs tools 1.50.0 was released on 7 February 2023.

Security
CVE-2022-2211
https://bugzilla.redhat.com/show_bug.cgi?id=2100862

A buffer overflow was found in the --key option of several guestfs tools. For more
information on this low severity bug see the bug report above (Laszlo Ersek).

New virt-drivers tool
This new tool can examine a disk image to determine:

• Whether it uses BIOS or UEFI for booting

• What bootloader it uses (Linux only)

• What kernels may be chosen at boot time (Linux only)

• What device drivers (kernel modules) are installed

This is useful for determining how (or if) a guest can boot on a virtualization
hypervisor.

virt-customize
--selinux-relabel is now the default for SELinux guests. You no longer need to specify
this flag. In the rare case where you don't want to relabel a guest after customizing it,
you can use --no-selinux-relabel. Note this is not needed for non-SELinux guests, it will
do the right thing automatically (Laszlo Ersek).

New --inject-qemu-ga and --inject-virtio-win operations which respectively inject QEMU
Guest Agent and virtio-win drivers into Windows guests.

Rocky Linux guests are now supported (thanks Harry Benson).

virt-inspector
Virt-inspector now outputs the new <build_id> element containing the guest build ID, if
using libguestfs ≥ 1.50.

virt-sysprep
New "lvm-system-devices" operation for removing LVM2's system.devices file. This avoids
certain problems when cloning a VM (Laszlo Ersek).

Virt-sysprep supports guests using LUKS logical volumes on top of LVM (Laszlo Ersek).

Common changes
All the tools supporting the --key option can now use Clevis/Tang to decrypt full disk
encryption using this network-based scheme (Laszlo Ersek).

Build changes
Note that libguestfs now requires minimum OCaml 4.04. It will not compile on RHEL 6.

Note that libosinfo is a new required dependency.

OCaml 4.14 is now supported.

"./configure --disable-ocaml" and "./configure --disable-perl" now disable the OCaml- and
Perl-based tools respectively (thanks Simon Walter).

Experimental support for compiling on macOS.

When running "make check-valgrind", Valgrind logs are no longer written to separate files
under tmp/. Instead the output is written to the normal test-name.log file.
