[PATCH] [v3] ddrescue mapfile filter
by François Revol
This allows to overlay bad sectors according to the mapfile generated by
ddrescue, to then see where sectors are used using fsck and trying to
copy files around.
Should now be mature enough to be useful to someone else.
And we have a proper test also.

+=head1 NAME
+
+nbdkit-ddrescue-filter - nbdkit filter for serving from ddrescue dump
+
+=head1 SYNOPSIS
+
+ nbdkit --filter=ddrescue plugin [plugin-args...] ddrescue-mapfile=file.map
+
+ nbdkit --filter=ddrescue file file=file.img ddrescue-mapfile=file.map [plugin-args...]
+
+=head1 DESCRIPTION
+
+C<nbdkit-ddrescue-filter> is a filter for L<nbdkit(1)> which overlays
+bad blocks according to a GNU L<ddrescue(1)> mapfile. This is mainly useful
+for testing disk images recovered with ddrescue, to detect which files
+or filesystem structures are impacted, or attempting fsck on them.
+
+Note that the current implementation is read-only.
+
+=head1 EXAMPLES
+
+=over 4
+
+=item Expose a rescued disk image with detected bad sectors:
+
+ nbdkit --filter=ddrescue file file=disk.img ddrescue-mapfile=disk.map
+
+The above command serves the disk image disk.img and maps the bad
+sectors listed in disk.img so that read attempts on them do not return
+a valid block full of zeroes.
+
+=back
+
+=head1 PARAMETERS
+
+The C<ddrescue-mapfile> parameter must point to a valid GNU ddrescue
+mapfile.
+
+=head1 DATA FORMAT
+
+The file pointed to by the C<ddrescue-mapfile> parameter should
+conform to the format of a GNU L<ddrescue(1)> mapfile.
+
+=head1 FILES
+
+=over 4
+
+=item F<$filterdir/nbdkit-ddrescue-filter.so>
+
+The filter.
+
+Use C<nbdkit --dump-config> to find the location of C<$filterdir>.
+
+=back
+
+=head1 VERSION
+
+C<nbdkit-ddrescue-filter> first appeared in nbdkit 1.22.

+=head1 NAME
+
+nbdkit-ddrescue-filter - nbdkit filter for serving from ddrescue dump
+
+=head1 SYNOPSIS
+
+ nbdkit --filter=ddrescue plugin [plugin-args...] ddrescue-mapfile=file.map
+
+ nbdkit --filter=ddrescue file file=file.img ddrescue-mapfile=file.map [plugin-args...]
+
+=head1 DESCRIPTION
+
+C<nbdkit-ddrescue-filter> is a filter for L<nbdkit(1)> which overlays
+bad blocks according to a GNU L<ddrescue(1)> mapfile. This is mainly useful
+for testing disk images recovered with ddrescue, to detect which files
+or filesystem structures are impacted, or attempting fsck on them.
+
+Note that the current implementation is read-only.
+
+=head1 EXAMPLES
+
+=over 4
+
+=item Expose a rescued disk image with detected bad sectors:
+
+ nbdkit --filter=ddrescue file file=disk.img ddrescue-mapfile=disk.map
+
+The above command serves the disk image disk.img and maps the bad
+sectors listed in disk.img so that read attempts on them do not return
+a valid block full of zeroes.
+
+=back
+
+=head1 PARAMETERS
+
+The C<ddrescue-mapfile> parameter must point to a valid GNU ddrescue
+mapfile.
+
+=head1 DATA FORMAT
+
+The file pointed to by the C<ddrescue-mapfile> parameter should
+conform to the format of a GNU L<ddrescue(1)> mapfile.
+
+=head1 FILES
+
+=over 4
+
+=item F<$filterdir/nbdkit-ddrescue-filter.so>
+
+The filter.
+
+Use C<nbdkit --dump-config> to find the location of C<$filterdir>.
+
+=back
+
+=head1 VERSION
+
+C<nbdkit-ddrescue-filter> first appeared in nbdkit 1.22.

[v2v PATCH] libvirt: make use of libvirt's default auth handler (RHBZ#1838425)
by Pino Toscano
Use the default libvirt authentication handler as base for ours,
overriding it with our callback only in case we have a password to
supply.

These are derived from the FreeBSD functions here:

[PATCH virt-v2v] v2v: -o libvirt: Remove cache=none.
by Richard W.M. Jones
Traditionally if you did live migration (KVM to KVM), you had to
ensure that cache=none was set on all disks of the guest up front.
This was because of quirks in how NFS works (I think the close-to-open
consistency and the fact that during live migration both qemus have
the file open), and we had to assume the worst case that a guest might
be backed by NFS.
Because of this when virt-v2v converts a guest to run on KVM using
libvirt it sets cache=none.
This is not necessary with modern qemu. If qemu supports the
drop-cache property of the file block driver, which libvirt will
automatically detect for us, then libvirt live migration is able to
tell qemu to drop cached data at the right time even if the backing is
NFS.
It also had a significant performance impact. In some synthetic
benchmarks it could show 2 or 3 times slower performance.
Thanks: Ming Xie, Peter Krempa.

[v2v PATCH] vCenter: fix parsing of HTTP status string (RHBZ#1837328)
by Pino Toscano
vCenter 7 answers with an HTTP/2 status string, so we cannot extract
the status code from it by using fixed positions in that string.
Hence, pick the status code by reading what's after the whitespace.
Tested with vCenter 6.5 and 7.

[PATCH v4 00/34] Configurable policy for handling deprecated interfaces
by Markus Armbruster
This series extends QMP introspection to cover deprecation.
Additionally, new option -compat lets you configure what to do when
deprecated interfaces get used. This is intended for testing users of
the management interfaces. It is experimental.
-compat deprecated-input=<in-policy> configures what to do when
deprecated input is received. Available policies:
* accept: Accept deprecated commands and arguments (default)
* reject: Reject them
* crash: Crash
-compat deprecated-output=<out-policy> configures what to do when
deprecated output is sent. Available output policies:
* accept: Emit deprecated command results and events (default)
* hide: Suppress them
For now, -compat covers only deprecated syntactic aspects of QMP. We
may want to extend it to cover semantic aspects, CLI, and experimental
features.
PATCH 01-04: Documentation fixes
PATCH 05-10: Test improvements
PATCH 11-24: Add feature flags to remaining user-defined types and to
struct members
PATCH 25-26: New special feature 'deprecated', visible in
introspection
PATCH 27-34: New -compat to set policy for handling stuff marked with
feature 'deprecated'
v4:
PATCH 05+07: Temporary memory leak plugged [Marc-André]
PATCH 23: Rewritten [Marc-André]
PATCH 24: Comment typo [Marc-André]
PATCH 30: Memory leaks plugged
v3:
* Rebased, non-trivial conflicts in PATCH 01+26+27+34 due to RST
conversion and code motion
* PATCH 28-29: Old PATCH 28 split up to ease review
* PATCH 30-31: New
* PATCH 32-33: Old PATCH 29 split up to ease review
Comparison to RFC (24 Oct 2019):
* Cover arguments and results in addition to commands and events
* Half-baked "[RFC PATCH 18/19] qapi: Include a warning in the
response to a deprecated command" dropped
