Subject: [PATCH] New API: guestfs_device_name returning the drive name
For each drive added, return the name. For example calling this with
index 0 will return the string "/dev/sda". I called it
guestfs_device_name (not drive_name) for consistency with the existing
guestfs_device_index function.
You don't really need to call this function. You can follow the
advice here:
https://libguestfs.org/guestfs.3.html#block-device-naming
and assume that drives are added with predictable names like
"/dev/sda", "/dev/sdb", etc.
However it's useful to expose the internal guestfs_int_drive_name
function since especially handling names beyond index 26 is tricky
(https://rwmj.wordpress.com/2011/01/09/how-are-linux-drives-named-beyond-drive-26-devsdz/)

Subject: [PATCH] daemon/inspect_fs_unix: recognize modern Pardus GNU/Linux
releases
Recent Pardus releases seem to have abandoned the original
"/etc/pardus-release" file, which the current Pardus detection, from
commit 233530d3541d ("inspect: Add detection of Pardus.", 2010-10-29), is
based upon.
Instead, Pardus apparently adopted the "/etc/os-release" specification
<https://www.freedesktop.org/software/systemd/man/os-release.html>, with
"ID=pardus". Extend the "distro_of_os_release_id" function accordingly.
Keep the original method for recognizing earlier releases.

From b97b90779d5ea261d5e737f073bb4ec5dc546511 Mon Sep 17 00:00:00 2001

Subject: [PATCH] guestfs_readdir(): rewrite with FileOut transfer, to lift
protocol limit
Currently the guestfs_readdir() API can not list long directories, due to
it sending back the whole directory listing in a single guestfs protocol
response, which is limited to GUESTFS_MESSAGE_MAX (approx. 4MB) in size.
Introduce the "internal_readdir" action, for transferring the directory
listing from the daemon to the library through a FileOut parameter.
Rewrite guestfs_readdir() on top of this new internal function:
- The new "internal_readdir" action is a daemon action. Do not repurpose
the "readdir" proc_nr (138) for "internal_readdir", as some distros ship
the binary appliance to their users, and reusing the proc_nr could
create a mismatch between library & appliance with obscure symptoms.
Replace the old proc_nr (138) with a new proc_nr (511) instead; a
mismatch would then produce a clear error message. Assume the new action
will first be released in libguestfs-1.48.2.
- Turn "readdir" from a daemon action into a non-daemon one. Call the
daemon action guestfs_internal_readdir() manually, receive the FileOut
parameter into a temp file, then deserialize the dirents array from the
temp file.
This patch sneakily fixes an independent bug, too. In the pre-patch
do_readdir() function [daemon/readdir.c], when readdir() returns NULL, we
don't distinguish "end of directory stream" from "readdir() failed". This
rewrite fixes this problem -- I didn't see much value separating out the
fix for the original do_readdir().

Subject: [PATCH] Add detection support for Rocky Linux (CentOS/RHEL-like)
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2030709
Thanks: label@rockylinux.org

RWMJ notes: I fixed the original patch so it compiled. This patch
sets osinfo to "rocky8", which doesn't exist in the osinfo db yet.
Arguably we might want to set this to "centos8", but we can see what
libosinfo decides to do. Here is partial virt-inspector output on a
Rocky Linux disk image:

Subject: [PATCH] guestfs_readdir(): minimize the number of send_file_write()
calls
In guestfs_readdir(), the daemon currently sends each XDR-encoded
"guestfs_int_dirent" to the library with a separate send_file_write()
call.
Determine the largest encoded size (from the longest filename that a
"guestfs_int_dirent" could carry, from readdir()'s "struct dirent"), and
batch up the XDR encodings until the next encoding might not fit in
GUESTFS_MAX_CHUNK_SIZE. Call send_file_write() only then.

Subject: [PATCH] launch-libvirt: place our virtio-net-pci device in slot 0x1e
The <qemu:commandline> trick we use for adding our virtio-net-pci device
in the libvirt backend can conflict with libvirtd's and QEMU's PCI address
assignment. Try to mitigate that by placing our device in slot 0x1e on the
root bus. In practice this could only conflict with a "dmi-to-pci-bridge"
device model, which libvirtd itself places in slot 0x1e. However, given
the XMLs we generate, and modern QEMU versions, libvirtd has no reason to
auto-add "dmi-to-pci-bridge". Refer to
<https://libvirt.org/formatdomain.html#controllers>.

Remove the handling of "iface" in the direct (QEMU) backend. Refresh the
documentation regarding both backends.

From f13297315495144775f6249e9e24dc5f18f6f902 Mon Sep 17 00:00:00 2001

Subject: [PATCH] lib: drive_create_data, drive: remove field "iface"
Representing "iface" in the "drive_create_data" and "drive" structures is
now useless; the direct backend ignores "iface", while the libvirt one
rejects it unless it is empty. Unify both backends -- make them both
ignore "iface". (Which only relaxes the libvirt backend, so it cannot
cause compatibility problems.) This lets us remove the fields. Update the
documentation as well.

Subject: [PATCH] lib: extract NETWORK_ADDRESS and NETWORK_PREFIX as macros
The 169.254.0.0/16 network specification (for the appliance) is currently
duplicated between the direct backend and the libvirt backend. In a
subsequent patch, we're going to need the network specification in yet
another spot; extract it now to the NETWORK_ADDRESS and NETWORK_PREFIX
macros (simply as strings).

Subject: [PATCH] launch-libvirt: add virtio-net via the standard <interface>
element
Starting with version 3.8.0, libvirt allows us to specify the network
address and network mask (as prefix) for SLIRP directly via the
<interface> element in the domain XML:
<https://libvirt.org/formatdomain.html#userspace-slirp-stack>. This means
we don't need the <qemu:commandline> hack for virtio-net on such versions.
Restrict the hack in construct_libvirt_xml_qemu_cmdline() to
libvirt<3.8.0, and generate the proper <interface> element in
construct_libvirt_xml_devices() on libvirt>=3.8.0.

Removing "--selinux-relabel" in commit 2f6a27f1077d ("generator/customize:

that invoke virt-customize and/or virt-sysprep with that option. Restore
the option, with no functionality tied to it.

Subject: [PATCH] daemon/rpm-c.c: Disable signature checking in librpm
Older distros (eg CentOS 6) used SHA-1 RPM package signatures which
some newer distros (eg RHEL 9.0) prevent us from verifying.
This resulted in packages with SHA-1 signatures being skipped by
librpm (there is a warning in debug output, but if you're not looking
at that then the package is silently ignored). In some cases
essential packages like the kernel were skipped, which would be
visible as a failure of virt-v2v. In other cases (eg virt-inspector)
you'd just see fewer installed packages in the <applications> list.
Since verifying package signatures is not essential for inspection,
disable this feature in librpm.

Subject: [PATCH] php: add arginfo to php bindings
Starting with PHP8, arginfo is mandatory for PHP extensions. This patch
updates the generator for the PHP bindings to generate the arginfo
structures, using the Zend API macros. Only basic arginfo is added,
without full documentation of argument and return types, in order to
ensure compatibility with as many versions of PHP as possible.

From 51ea2e3af9caa434e847ca74a86f5de5ade6058f Mon Sep 17 00:00:00 2001
From: Laszlo Ersek <lersek@redhat.com>
Date: Thu, 30 Jun 2022 14:20:47 +0200
Subject: [PATCH] introduce the "clevis_luks_unlock" API
Introduce a new guestfs API called "clevis_luks_unlock". At the libguestfs
level, it is quite simple; it wraps the "clevis luks unlock" guest command
(implemented by the "clevis-luks-unlock" executable, which is in fact a
shell script).
The complexity is instead in the network-based disk encryption
(Clevis/Tang) scheme. Useful documentation:
- https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html-single/security_hardening/index#configuring-automated-unlocking-of-encrypted-volumes-using-policy-based-decryption_security-hardening
- https://github.com/latchset/clevis#clevis
- https://github.com/latchset/tang#tang
The package providing "clevis-luks-unlock" is usually called
"clevis-luks", occasionally "clevis". Some distros don't package clevis at
all. Add the new API under a new option group (which may not be available)
called "clevisluks".

Subject: [PATCH] daemon: Add zstd support to guestfs_file_architecture
This is required so we can determine the file architecture of
zstd-compressed Linux kernel modules as used by OpenSUSE and maybe
other distros in future.
Note that zstd becomes a required package, but it is widely available
in current Linux distros.
The package names come from https://pkgs.org/download/zstd and my own
research.
