This is failing on a new test I added, but it's failing because of how
a particular package is built in OpenSUSE.
The new test is:
https://gitlab.com/nbdkit/libnbd/-/commit/c833fa1226092fd51b1211fa195a2a3...
which tries to test libnbd client with TLS enabled against nbd-server.
nbd-server in OpenSUSE gives this error:
Error: inetd mode requires syslog
Exiting.
which means it was compiled without --enable-syslog.
I notice that the related test is skipped:
SKIP: interop-nbd-server
========================
Test skipped based on ci/skipped_tests file
SKIP interop-nbd-server (exit status: 77)
The format of ci/skipped_tests is pretty odd. Is this patch OK?

[PATCH RFC 0/5] Subject: [PATCH RFC 0/5] qapi: Add feature flags to enum members
by Markus Armbruster
PATCH 1+2 add feature flags to enum members. Awkward due to an
introspection design mistake; see PATCH 1 for details. Feedback
welcome, in particular from management application guys.
PATCH 3+4 implement policy deprecated-input={reject,crash} for enum
values.
Policy deprecated-output=hide is not implemented, because we can't
hide a value without hiding the entire member, which is almost
certainly more than the requester of this policy bargained for.
Perhaps we want a new policy deprecated-output=crash to help us catch
unwanted use of deprecated enum values. Thoughts?
PATCH 5 puts the new feature flags to use. It makes sense only on top
of Vladimir's deprecation of drive-backup. See its commit message for
a reference.
Based on my "[PATCH 00/22] qapi: Remove simple unions from the schema
language".
Based-on: Message-Id: <20210913123932.3306639-1-armbru(a)redhat.com>

[libnbd PATCH] build: allow OCaml programs using libnbd to be compiled against build dir
by Laszlo Ersek
Port libguestfs commit bf61bf7355d3 ("build: Allow OCaml programs using
libguestfs to be compiled against build dir.", 2020-03-12) to libnbd.
This allows C+OCaml programs, such as virt-v2v, to find a just built, but

[PATCH v2] Go bindings: fix "C array of strings" -- char** -- allocation
by Laszlo Ersek
The current "arg_string_list" and "free_string_list" implementations go
back to commit b6f01f32606d ("Add Go (language) bindings.", 2013-07-03).
There are two problems with them:
- "free_string_list" doesn't actually free anything,
- at the *first* such g.Internal_test() call site that passes an
Ostringlist member inside the Optargs argument, namely:
> g.Internal_test ("abc",
> string_addr ("def"),
> []string{},
> false,
> 0,
> 0,
> "123",
> "456",
> []byte{'a', 'b', 'c', '\000', 'a', 'b', 'c'},
> &guestfs.OptargsInternal_test{Ostringlist_is_set: true,
> Ostringlist: []string{}
> }
> )
the "golang/run-bindtests" case crashes:
> panic: runtime error: cgo argument has Go pointer to Go pointer

One pattern to solve the problem has been shown on stackoverflow [2].
Thus, rewrite the "arg_string_list" and "free_string_list" functions
almost entirely in C, following that example.
While this approach is not the most idiomatic Go, as a solution exists
without C helper functions [3], it should still be acceptable, at least as
an incremental improvement, for letting "golang/run-bindtests" pass.

ANNOUNCE: nbdkit 1.28 and libnbd 1.10 released
by Richard W.M. Jones
nbdkit is a Network Block Device (NBD) server with stable plugin ABI
and permissive license. libnbd is an NBD client library.
I'm pleased to announce the latest stable releases of both projects:
nbdkit 1.28.0 and libnbd 1.10.0. You can download both from the
download directories here:
https://download.libguestfs.org/nbdkit/
https://download.libguestfs.org/libnbd/
Release notes are online here and attached below:
https://libguestfs.org/nbdkit-release-notes-1.28.1.html
https://libguestfs.org/libnbd-release-notes-1.10.1.html
Rich.
----------------------------------------------------------------------
These are the release notes for nbdkit stable release 1.28. This
describes the major changes since 1.26.
nbdkit 1.28.0 was released on 23 September 2021.
Security
CVE-2021-3716 reset structured replies on starttls
nbdkit was vulnerable to injected plaintext when upgrading to a secure
connection. For the full announcement see
https://www.redhat.com/archives/libguestfs/2021-August/msg00083.html
(Eric Blake).
All past security issues and information about how to report new ones
can be found in nbdkit-security(1).
Plugins
nbdkit-data-plugin(1) has new "le<NN>:" and "be<NN>:" prefixes for
little and big endian words. Also the plugin tries much harder to
optimize expressions. The test suite has been greatly expanded to
catch potential regressions.
nbdkit-floppy-plugin(1) now allows you to reserve free space (Nolan
Leake).
nbdkit-ssh-plugin(1) no longer references SHA1 host keys as part of the
effort to remove insecure algorithms (Daniel Berrangé).
nbdkit-vddk-plugin(1) reports "can_flush" and "can_fua" based on what
the version of VDDK supports. New debug flag -D vddk.stats=1 prints
the amount of time spent in VDDK calls on exit which can be useful for
profiling performance.
Filters
nbdkit-cow-filter(1) and nbdkit-cache-filter(1) no longer break up
large read requests into page-sized requests. In addition the default
block size for both filters is now 64K. Both changes greatly improve
performance.
nbdkit-cache-filter(1) has a new "cache-on-read=/PATH" parameter
allowing callers to enable and disable the cache-on-read feature at
runtime. Also there is a new "cache-min-block-size" parameter letting
you select the block size at runtime (thanks Martin Kletzander).
nbdkit-cow-filter(1) has a new "cow-on-read" parameter which works
similarly to the corresponding cache filter feature. The new
"cow-block-size" parameter lets you select the block size at runtime.
nbdkit-cow-filter(1) has less verbose debugging. To restore the old
debug output use -D cow.verbose=1
nbdkit-delay-filter(1) has new "delay-open" and "delay-close"
parameters to inject delays when clients connect and disconnect. Delay
filter parameters are now parsed more accurately (thanks Ming Xie).
Language bindings
The OCaml bindings now call "caml_shutdown" when unloading the plugin.
This causes "Stdlib.at_exit" handlers to run correctly, closes file
descriptors, releases dependent shared libraries and frees memory.
Valgrind on OCaml plugins should not show any false positives about
leaked memory.
OCaml and Python bindings may now use the ".cleanup" method.
References to Python 2 in nbdkit-python-plugin(3) have been removed.
Server
Fix captive nbdkit $uri variable so when TLS is used the URI is
constructed with the "nbds:" prefix. Additionally add a new variable
$tls which can be used by the subprocess to tell if TLS is enabled.
Debug messages are now printed atomically. This means that debug
messages are no longer broken up across multiple lines if there are
other processes writing to stderr at the same time (which often
happened when using captive nbdkit).
Enhanced valgrind support (./configure --enable-valgrind) can now be
enabled safely and with no performance impact even in production builds
(Eric Blake).
API
Plugins or filters using "nbdkit_nanosleep" now don't hang if the
client closes the socket abruptly (thanks Ming Xie).
Bug fixes
nbdkit-data-plugin(1) and nbdkit-memory-plugin(1) using
allocator=malloc no longer crash because of memory corruption in some
corner cases (only seen on s390x, but could happen on other
architectures). Meanwhile "allocator=zstd" no longer crashes when
zeroing unallocated space.
Tests
Tests now use the new "GLIBC_TUNABLES" feature, replacing
"MALLOC_CHECK_" on glibc ≥ 2.34 (thanks Eric Blake, Siddhesh
Poyarekar).
Build
configure.ac now uses spaces consistently, and has been modernized to
support the latest autotools (Eric Blake).
podwrapper.pl has been unified (almost) with the copy in libnbd.
Continue fuzzing using AFL++. Updated the fuzzing documentation.

----------------------------------------------------------------------
These are the release notes for libnbd stable release 1.10. This
describes the major changes since 1.8.
libnbd 1.10.0 was released on 23 September 2021.
Security
There were no security bugs found in libnbd during this release cycle.
If you find a security issue, please read SECURITY in the source
(online here: https://gitlab.com/nbdkit/libnbd/blob/master/SECURITY).
To find out about previous security issues in libnbd, see
libnbd-security(3).
New APIs
No new APIs were added in 1.10.
Enhancements to existing APIs
nbd_get_uri(3) no longer returns service names (eg.
"nbd://localhost:nbd"). Instead it always returns raw port numbers for
portability.
nbd_connect_uri(3) now supports "tls-certificates=DIR" query parameter,
making it much easier to connect to servers using TLS with X.509
certificates. Also error messages from this API have been improved in
the case of some common URI user errors.
Python "nbd.aio_connect" implements support for "AF_UNIX" sockets.
Fix invalid use of "unsafe.Pointer" in Go bindings.
Tools
nbdcopy(1) now uses a default request size of 2M (instead of 32M).
This default performs better in most cases.
nbdinfo(1) has a new --map --totals mode which displays a summary of
the map. Also new --can and --is options let you test export
properties (eg. --is read-only).
nbdinfo(1) --map option uses "data" instead of "allocated" because of
ambiguity about what "allocated" means (Eric Blake, Nir Soffer).
nbdinfo(1) shows the export size in both bytes and human units (like
"1K"). The machine-parsable JSON output has not changed.
nbdfuse(1) now supports efficient zeroing. Note this requires Linux
kernel ≥ 5.14.
nbdsh(1) has new option -n which avoids creating the implicit handle
"h". Also new option -v which enables debugging. Also the initial
help banner is now context sensitive giving more relevant information
depending on how nbdsh was invoked.
Tests
CI tests were greatly enhanced and many platform-specific fixes were
made. To view the latest CI tests and results see:
https://gitlab.com/nbdkit/libnbd/-/pipelines (Martin Kletzander).
Tests now use the new "GLIBC_TUNABLES" feature, replacing
"MALLOC_CHECK_" on glibc ≥ 2.34 (thanks Eric Blake, Siddhesh
Poyarekar).
Other improvements and bug fixes
The nbdcopy(1) progress bar should be displayed more accurately in
multithreaded mode.
Documentation
nbd_connect(3) and nbd_aio_connect(3) documentation has been revised
and improved.
More consistent option styling is used throughout the documentation.
podwrapper.pl has been unified (almost) with the copy in nbdkit.
Build
configure.ac now uses spaces consistently, and has been modernized to
support the latest autotools (Eric Blake).
We now warn about large stack frames, and a few places which used large
stack frames have been fixed.
Continue fuzzing using AFL++. Updated the fuzzing documentation.
Fix building from git with --disable-ocaml. As long as only "ocamlc"
is installed, the generator should still be built and run (Martin
Kletzander).

ANNOUNCE: libguestfs 1.46 released
by Richard W.M. Jones
libguestfs is a library for accessing and modifying virtual machine
disk images. I'm pleased to announce the latest stable version. The
release notes are below and you can download this version from the
download directory here:
https://download.libguestfs.org/
Rich.
RELEASE NOTES FOR LIBGUESTFS 1.46
(https://libguestfs.org/guestfs-release-notes-1.46.1.html)
The big news in this release is that the virt tools like
virt-builder(1), virt-cat(1), virt-customize(1), virt-df(1), and many
more were moved to a new project. The temporary repository for the new
guestfs-tools project is here:
https://github.com/rwmjones/guestfs-tools while we set up a permanent
home for it on gitlab. The tarballs containing the tools are here:
https://download.libguestfs.org/guestfs-tools/
Spinning out all of the tools into a new repository has made libguestfs
a bit easier and simpler to build and manage, and allows us to focus on
just being the API.
Note that the tools guestfish(1) (which is really a "shell API"),
guestmount(1), libguestfs-test-tool(1) and virt-rescue(1) are still
part of the libguestfs repo.
The not quite so big news is that we have moved away from FreeNode to
Libera Chat for IRC. The new channel on Libera is called "#guestfs"
(thanks Daniel Berrangé).
Language bindings
Libguestfs is now compatible with Go 1.16, and defines a Go module
(thanks Gianfranco Costamagna).
Memory leaks in Python APIs that returned structs are fixed (thanks
朱丹).
Python PyPi code has been relicensed to LGPLv2+ (from GPLv2+).
Inspection
Inspection of RPM guests now uses librpm instead of trying to parse the
Berkeley DB directly. Since most RPM-based guests have replaced BDB
with sqlite this allows us to read these newer guests while retaining
compatibility with the older guests (thanks Panu Matilainen).
Inspection of RHEL 8+ with split /usr configuration has been made more
reliable.
Inspection of Windows Server 2022 should now work correctly (Yongkui
Guo).
API
New APIs
No new APIs were added in libguestfs 1.46.
Other API changes
The output of the "guestfs_cap_get_file" API has changed slightly
because of changes in the underlying libcap. This isn't strictly
speaking an API break because the new output is a still valid but more
compact description of file capabilities, but because it is different
it may cause problems for users of the API.
The "guestfs_mkfs_btrfs" API now ignores the "allocstart" parameter
since it was deprecated by btrfs 4.14.1 and later removed.
"guestfs_isoinfo_*" APIs now directly parse the CD Primary Volume
Descriptor instead of using an external tool. The APIs should appear
to work exactly the same (thanks Thomas Schmitt).
You can now force the appliance to use KVM or fail if not supported
(Sam Eiderman).
Because of a change to XFS in version 5, disabling lazy-counters no
longer works. The API still works for earlier versions of XFS (Laszlo
Ersek).
Build changes
The build now uses and requires PCRE2 (instead of PCRE).
This version requires libvirt ≥ 7.1.0, if libvirt is enabled.
gnulib is no longer bundled with libguestfs, making builds from git
much simpler.
Perl "Sys::Virt" (libvirt bindings for Perl) are no longer required by
libguestfs.
The code has been compiled with both LTO and GCC -fanalyzer and many
bugs and warnings fixed.
Allow projects like guestfs-tools and virt-v2v to be compiled with
locally built (but not installed) libguestfs (Laszlo Ersek).
Tests now run in parallel (many additional fixes by Laszlo Ersek).
Work around RAID0 regression in Linux 3.14/5.4 (Laszlo Ersek).
Support for RISC-V (Heinrich Schuchardt).
Support for building on Alma and Cloud Linux (Александр Кравченко).
Fix to compile with OCaml 4.12.
The tarball no longer includes the ChangeLog file. To get a detailed
changelog, please look at the upstream git repository.
Don't assume bash in the ./configure script (Martin Kletzander).
Fix ./configure --with-distro option (Alexandre Iooss).
Various fixes for qemu 6.1.
Fix creating appliance dependencies on Debian (Hilko Bengen).
Update appliance packages on SUSE and several other improvements to the
init script (Olaf Hering).
Internals
We now use the qemu / libvirt feature -cpu max to select the best CPU
to run the appliance. This should improve performance for things like
encrypted disks (Daniel Berrangé).
When passing the appliance filesystem UUID to supermin we now read it
directly out of the appliance instead of using the file(1) program.
This is more reliable, especially as file often breaks or changed its
output.
The qemu -enable-fips option is no longer used. It was not needed and
has been deprecated by qemu.
On Fedora, pull in glibc-gconv-extra to fix the "guestfs_syslinux" API
(Yongkui Guo).
We no longer use qemu's sga (Serial Graphics Adapter) option ROM,
instead using the equivalent seabios feature.
