Subject: [PATCH] readahead: Rewrite this filter so it prefetches using .cache
The previous readahead filter did not work well and we have stopped
using it in virt-v2v. However the concept is a good one if we can
make it work. This commit completely rethinks the filter.
Now, in parallel with the ordinary pread command, we issue a prefetch
(ie. .cache) to the underlying plugin for the data immediately
following the pread. For example a simple sequence of operations:
t=1 pread (offset=0, count=65536)
t=2 pread (offset=65536, count=65536)
t=3 pread (offset=131072, count=65536)
would become:
t=1 pread (offset=0, count=65536) <--\ issued
cache (offset=65536, count=65536) <--/ in parallel
t=2 pread (offset=65536, count=65536)
cache (offset=131072, count=65536)
t=3 pread (offset=131072, count=65536)
cache (offset=196608, count=65536)
This requires that the underlying filter(s) and plugin chain can
actually do something with the .cache request. If this is not the
case then the filter does nothing (but it will print a warning). For
plugins which don't have native support for prefetching, it is
sufficient to insert nbdkit-cache-filter after this filter.
(nbdkit-cow-filter can also be used with cow-on-cache=true, but that
is more useful for advanced users who are already using the cow
filter).
The implementation creates a background thread per connection to issue
the parallel .cache requests. This is safer than the alternative (one
background thread in total) since we don't have to deal with the
problem of cache requests being issued with the wrong export name or
stale next pointer. The background thread is controlled by a queue of
commands, with the only possible commands being "cache" or "quit".
Because the background thread issues parallel requests on the same
connection, the underlying plugin must support the parallel thread
model, otherwise we would be violating the plugin's thread model. It
may be possible in future to open a new connection from the background
thread (but with the same exportname), which would lift this
restriction to at least serialize_requests. Because of the current
limitation, nbdkit-curl-plugin cannot use prefetch.

=head1 NAME
-nbdkit-readahead-filter - prefetch data when reading sequentially
+nbdkit-readahead-filter - prefetch data ahead of sequential reads
=head1 SYNOPSIS
- nbdkit --filter=readahead plugin
+ nbdkit --filter=readahead PLUGIN
+
+ nbdkit --filter=readahead --filter=cache PLUGIN
+
+ nbdkit --filter=readahead --filter=cow PLUGIN cow-on-cache=true
=head1 DESCRIPTION
C<nbdkit-readahead-filter> is a filter that prefetches data when the
-client is reading sequentially.
+client is reading.
-A common use for this filter is to accelerate sequential copy
-operations (like S<C<qemu-img convert>>) when plugin requests have a
-high overhead (like L<nbdkit-curl-plugin(1)>). For example:
-
- nbdkit -U - --filter=readahead curl https://example.com/disk.img \
- --run 'qemu-img convert $nbd disk.img'
+When the client issues a read, this filter issues a parallel prefetch
+(C<.cache>) for subsequent data. Plugins which support this command
+will prefetch the data, making sequential reads faster. For plugins
+which do not support this command, you can inject
+L<nbdkit-cache-filter(1)> below (after) this filter, giving
+approximately the same effect. L<nbdkit-cow-filter(1)> can be used
+instead of nbdkit-cache-filter, if you add the C<cow-on-cache=true>
+option.
The filter uses a simple adaptive algorithm which accelerates
-sequential reads, but has a small penalty if the client does random
-reads. If the client mixes reads with writes or write-like operations
-(trimming, zeroing) then it will work but there can be a large
-performance penalty.
+sequential reads and requires no further configuration.
+
+=head2 Limitations
+
+In a number of significant cases this filter will do nothing. The
+filter will print a warning message if this happens.
+
+=over 4
+
+=item Thread model must be parallel
+
+For example L<nbdkit-curl-plugin(1)> only supports
+C<serialize_requests>, and so this filter cannot perform prefetches in
+parallel with the read requests.
+
+We may be able to lift this restriction in future.
+
+=item Underlying filters or plugin must support C<.cache> (prefetch)
+
+Very many plugins do not have the concept of prefetching and/or
+do not implement the C<.cache> callback, and so there is no
+way for this filter to issue prefetches.
+
+You can usually get around this by adding I<--filter=cache> after this
+filter as explained above. It may be necessary to limit the total
+size of the cache (see L<nbdkit-cache-filter(1)/CACHE MAXIMUM SIZE>).
+
+=item Clients and kernels may do readahead already
+
+It may be the case that NBD clients are already issuing
+C<NBD_CMD_CACHE> (NBD prefetch) commands. It may also be the case
+that your plugin is using local file functions where the kernel is
+doing readahead. In such cases this filter is not necessary and may
+be pessimal.

Subject: [PATCH] readahead: Fix test
The previous test turned out to be pretty bad at testing the new
filter. A specific problem is that the filter starts a background
thread which issues .cache requests, while on the main connection
.pread requests are being passed through. The test used
--filter=readahead --filter=cache with the cache filter only caching
on .cache requests (since cache-on-read defaults to false), so only
caching requests made by the background thread.
main thread
client ---- .pread ----- delay-filter -------> plugin
\
\ background thread
.cache --- cache-filter
Under very high load, the background thread could be starved. This
means no requests were being cached at all, and all requests were
passing through the delay filter. It would appear that readahead was
failing (which it was, in a way).
It's not very easy to fix this since readahead is best-effort, but we
can go back to using a simpler plugin that logs reads and caches and
check that they look valid.
Update: commit 2ff548d66ad3eae87868402ec5b3319edd12090f
(cherry picked from commit db1e3311727c6ecab3264a1811d33db1aa45a4d0)

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.

+=head2 Troubleshooting performance problems
+
+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

Because gnutls_pbkdf2 is missing there's no chance of making this
filter work on this platform so it's best to compile it out.

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

In VDDK >= 7 it is possible to display the logical and physical sector
size in debug output.
This commit also extends the test since this flag was not tested
before.

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.
Fixes: commit 8700649d147948897f3b97810a1dff37924bdd6e

Subject: [PATCH] tests: luks: Reduce time taken to run these tests
Under valgrind they ran very slowly. Turns out valgrinding over
GnuTLS hashing code is not pretty. About half the time seems to be
taken opening the keyslot, and the rest copying the data.
This change reduces the time (under valgrind) from 15 minutes 45 seconds
to about 6 mins 30 seconds.

Subject: [PATCH] Add nbdkit.parse_size() Python function.
This enables Python plugins to parse sizes the same way as C plugins.
I'm not sure about the best way to test this - input is appreciated.
I'm not too happy with the way this code is tested. It workes, but putting the tests into
test-python-plugin.py feels misplaced: this file is intended to support the unit tests in
test_python.py, not run its own unit tests.

Subject: [PATCH] curl: Don't document curl plugin + readahead filter
nbdkit readahead filter does not support plugins which do not use the
parallel thread model.

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.

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.

Subject: [PATCH] scan: Fix bound so we don't try to prefetch beyond end of
disk
An off-by-one error in the bound could cause the filter to try to
prefetch beyond the end of the underlying plugin. This would cause
nbdkit to crash with this assertion failure:
nbdkit: backend.c:782: backend_cache: Assertion `backend_valid_range (c, offset, count)' failed.
The sequence of events was:
- scan filter background thread started
- client reads to the end of the disk
- background thread skips ahead to end of disk (offset == size)
- background thread tries to prefetch from this point
In the final step the calculations caused to the background thread to
prefetch a scan-size block beyond the end of the plugin.
Fixes: commit 65c20a09ceacb4431986a2982f2c2e746df63fcb

Subject: [PATCH] vddk: Move config, debug/error and utility functions around
Move the functions so they are nearer to where they are used.
Introduce a utils.c file for utility functions.
This is just code rearrangement with no other effects.

From 239df6ee9583bc520e9a3e18f0c0d8e58602fb5c Mon Sep 17 00:00:00 2001

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
Ported from libnbd:
- commit dc9ae0174ab1384081a57a8d54b10f8147ea6430
- commit f6c06a3b4d87fe976a96ea04f8da1f22b2531dbd

Subject: [PATCH] rate: Allow burstiness to be controlled
Previously it was fixed at 2.0 seconds. Allowing it to be adjusted
upwards could help with large, lumpy requests.

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.
Ported from libnbd commit 985dfa72ae2e41901f0af21e7205ef85428cd4bd.

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.

already fixed this for Ruby etc, this commit fixes it for Tcl and Lua.

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

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.

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).
