Subject: [PATCH] vddk: Refactor how -D vddk.stats=1 is collected
In order to allow us to collect more per-API stats, introduce a global
struct per API for storing these stats.

Subject: [PATCH] vddk: Simplify and consolidate VDDK_CALL_START/END macros
We don't need the VDDK_CALL_*_DATAPATH versions of these macros
because the compiler is able to optimize some static strcmps.
Furthermore we can remove extra { .. } when the macros are applied.
(cherry picked from commit 3ea0ed6582faa8f800b7a2a15d58032917a21bd5)

+VDDK has very uneven performance with some operations being very slow.
+This plugin has options to allow you to debug performance issues. If
+your application has a debug or diagnostic setting, add the following
+nbdkit command line options:
+
+ -v -D nbdkit.backend.datapath=0 -D vddk.datapath=0 -D vddk.stats=1
+
+C<-v> enables verbose messages and the two datapath options I<disable>
+the very verbose per-read/-write messages. C<-D vddk.stats=1> enables
+a summary when nbdkit exits of the cumulative time taken in each VDDK
+function, the number of times each function was called, and (for read
+and write) the number of bytes transferred. An example of what those
+stats look like can be found here:
+L<https://gitlab.com/nbdkit/nbdkit/-/commit/5c80f0d290db45a679d55baf37ff39bacb8ce7ec>
+
+You can interpret the stats as follows:
+
+=over 4
+
+=item C<Read>
+
+The cumulative time spent waiting for VDDK to return from
+C<VixDiskLib_Read> calls, the number of times this function was
+called, and the total bytes read. You can use this to determine the
+read bandwidth to the VMware server.
+

+

+

Subject: [PATCH] vddk: Include VDDK major library version in --dump-plugin

Although it doesn't seem to be possible to get the precise VDDK
version, With a relatively simple change we can at least return the
VDDK major version. Currently this can be 5, 6 or 7.

Subject: [PATCH] vddk: Only print vddk_library_version when we managed to load
the library
Because --dump-plugin calls load_library (false) it won't fail if we
didn't manage to load the library. This results in library_version
being 0, which we printed incorrectly.
Resolve this problem by not printing the vddk_library_version entry in
this case.

Drop support for VDDK 5.5.5 (released in 2015) and 6.0 (released the

Subject: [PATCH] vddk: Start to split VDDK over several files
This change doesn't do anything except move some definitions into the
header file vddk.h, but it allows future commits to split up the very
large vddk.c file.

Since we now require and check that VDDK >= 6.5, we can assume that
VixDiskLib_Flush is always available.

Subject: [PATCH] vddk: Simplify detection of VDDK symbols and baseline 6.5
Make all symbols from VDDK 6.5 into required symbols and use a single
error message function if one of these is missing. The new error is:
nbdkit: error: required VDDK symbol "VixDiskLib_Wait" is
missing. VDDK version must be >= 6.5. See nbdkit-vddk-plugin(1) man
page section "SUPPORTED VERSIONS OF VDDK". Original dlopen error:
vmware-vix-disklib-distrib/lib64/libvixDiskLib.so.6: undefined
symbol: VixDiskLib_Wait
Remove the extra check and assert.
Be more consistent about #define OPTIONAL_STUB(fn,ret,args) STUB(fn,ret,args)
when we want the optional and required stubs to do the same thing.
(cherry picked from commit ec0d22e61881efa39a69d02ccb9e4ede8bf95e75)

Subject: [PATCH] common/utils/test-vector.c: Add vector benchmarks
The generic vector reallocs on every append. Add benchmarks to measure
the cost with uint32 vector (used for copying extents) and the effect of
reserving space upfront.
The tests show that realloc is pretty efficient, but calling reserve
before the appends speeds the appends up significantly.
NBDKIT_BENCH=1 ./test-vector
bench_reserve: 1000000 appends in 0.004503 s
bench_append: 1000000 appends in 0.014986 s
The new benchmarks do not run by default to avoid trouble in CI on
overloaded machines or under qemu emulation.
A new target added to run all benchmaks:
make bench

Subject: [PATCH] common/urils/vector.c: Optimize vector append
Minimize reallocs by growing the backing array by factor of 1.5.
Testing show that now append() is fast without calling reserve()
upfront, simplifying code using vector.
NBDKIT_BENCH=1 ./test-vector
bench_reserve: 1000000 appends in 0.004496 s
bench_append: 1000000 appends in 0.004180 s
This can make a difference in code appending millions of items.

Subject: [PATCH] common/utils/vector: Rename `alloc` to `cap`
The `alloc` field is the maximum number of items you can append to a
vector before it need to be resized. This may confuse users with the
size of the `ptr` array which is `alloc * itemsize`. Rename to "cap",
common term for this property in many languages (e.g C++, Rust, Go).
Tested with "make check". Tests requiring root or external libraries
(vddk) not tested.
Ported from libnbd commit e3c7f02a2a844295564c832108d36c939c4e4ecf.

Since commit 1eecf15fc3 ("vddk: Implement parallel thread model") we

handling is believed to be safe and in conformity with the VDDK
documentation. Remove obsolete documentation contradicting this.

Subject: [PATCH] file: Fix implementation of cache=none for writes
When testing virt-v2v we found that cache=none had very pessimal
performance in its current implementation when writing. See:
https://github.com/libguestfs/virt-v2v/commit/ac59d3b2310511b1537d408b675b19ec9a5d384e
However we know of a much better implementation - the one in nbdcopy.
This commit copies that implementation (for writes only).
A simple test is to do:
$ ./nbdkit file out.img cache=none --run 'nbdcopy fedora-33.img $uri'
and then check the cache usage of the output file, which should be
around 0% (using https://github.com/Feh/nocache):
$ cachestats out.img
pages in cache: 409/1572864 (0.0%) [filesize=6291456.0K, pagesize=4K]
For modular virt-v2v doing a local disk to local disk conversion:
- before this change, without cache=none
virt-v2v took 93.7 seconds, 19.1% pages cached in output file
- before this change, enabling cache=none
virt-v2v took 125.4 seconds, 0.0% pages cached in output file
^^^ this is the bad case which caused the investigation
- after this change, without cache=none
virt-v2v took 93.2 seconds, 19.1% pages cached in output file
- after this change, enabling cache=none
virt-v2v took 97.9 seconds, 0.1% pages cached in output file
I tried to adjust NR_WINDOWS to find an optimum. Increasing it made
no difference in performance but predictably caused a slight increase
in cached pages. Reducing it slowed performance slightly. So I
conclude that 8 is about right, but it probably depends on the
hardware.

Subject: [PATCH] tests: Add configure --disable-libguestfs-tests flag
This can be used to disable tests which need libguestfs*. We were
already doing that in a hackish way in the Fedora build on some
architectures. This makes it more supportable.
Note that you can use
./configure --enable-libguestfs --disable-libguestfs-tests
to enable the bindings but disable the tests.
The difference between without and with the new flag on an otherwise
fully configured Fedora machine:
# TOTAL: 286
# PASS: 273
# SKIP: 13
# TOTAL: 263
# PASS: 251
# SKIP: 12
* except for those which directly test for requirements using
expressions like:
requires guestfish --version
(cherry picked from commit c09ae98ff3b4b786565de4aa173274531a753d30)

Subject: [PATCH] vddk: Implement VMDK creation
Add the create=(true|false) parameter. Setting this to true causes
the VMDK local file to be created. Currently this is done on first
connection, but we might change that in future. Various other
parameters can be used to control aspects of the VMDK file.
(cherry picked from commit a39d5773afc3ebab7e5768118a2bccb89a654585)

Subject: [PATCH] vddk: Allow create-hwversion to be specified as a number
This gives us a bit of future-proofing so we don't always need to add
new hardware versions immediately. Another reason for this is that
VDDK allows you to specify seemingly any number here without
complaint.
Updates: commit a39d5773afc3ebab7e5768118a2bccb89a654585

From 222bce6b83421db1afdad24cf4e8ab7b1aa7b273 Mon Sep 17 00:00:00 2001
From: Laszlo Ersek <lersek@redhat.com>
Date: Tue, 18 Jan 2022 14:48:33 +0100
Subject: [PATCH] server/sockets: get rid of AI_ADDRCONFIG
The AI_ADDRCONFIG hint of getaddrinfo() is supposed to restrict the name
resolution to such address families (IPv4 vs. IPv6) for which the
resolving host has publicly routable addresses assigned.
The main problem with AI_ADDRCONFIG can be shown with the following
command line:
$ nbdkit -f -p 32776 -P pidfile -i ::1 --exit-with-parent null
On a host where ::1 is the only IPv6 address assigned (namely to the
loopback interface), the command fails with
> nbdkit: getaddrinfo: ::1: 32776: Address family for hostname not
> supported
due to the "publicly routable" requirement.
Remove AI_ADDRCONFIG from the getaddrinfo() hints, and as a replacement,
introduce the "-4" and "-6" options, similarly to netcat and ssh.
(1) This makes options of the form:
-i 127.0.0.1
-i ::1
work regardless of "public" IPv6 / IPv4 connectivity;
(2) options of the form
-i localhost
-i FQDN
will bind both IPv4 and IPv6 addresses of the desired interface(s);
(3) omitting the option "-i" will bind both IPv4 and IPv6 wildcard
addresses (0.0.0.0 and ::);
(4) the configurations in (2) and (3) can be restricted to IPv4 or IPv6
addresses by adding the "-4" or "-6" option, respectively.
Importantly, this change allows the "connect-tcp6" test case of libnbd to
pass on such hosts that have no IPv6 connectivity (i.e., where the only
assigned IPv6 address is ::1, namely on the loopback interface).
