53de966c3e build, dockerfiles: add support for detecting rustdoc
rustdoc is effectively a custom version of rustc, and it is necessary to
specify it in order to run doctests from Meson.  Add the relevant configure
option and environment variables.

0074a47147 meson: update to version 1.8.1
This adds several improvements to Rust support, including
native clippy and rustdoc targets, the "objects" keyword,
and running doctests.

Require it only when Rust support is requested, to avoid
putting a strict requirement on all build platforms for the
sake of an experimental feature.

5c54a36726 tests/unit/test-util-sockets: fix mem-leak on error object
The test fails with --enable-asan as the error struct is never freed.
In the case where the test expects a success but it fails, let's also
report the error for debugging (it will be freed internally).

6c54775584 tests/functional: Test both microblaze s3adsp1800 endianness variants
Now that the endianness of the petalogix-s3adsp1800 can be configured,
we should test that the cross-endianness also works as expected, thus
test the big endian variant on the little endian target and vice versa.

e1c9c80102 tests/functional/test_sparc64_tuxrun: Explicitly set the 'sun4u' machine
Use self.set_machine() to set the machine instead of relying on the
default machine of the binary. This way the test can be skipped in
case the machine has not been compiled into the QEMU binary.

c49dda7254 iotests: Filter out ZFS in several tests
Fiona reported that ZFS makes sparse file testing awkward, since:
- it has asynchronous allocation (not even 'fsync $file' makes du see
  the desired size; it takes the slower 'fsync -f $file' which is not
  appropriate for the tests)
- for tests of fully allocated files, ZFS with compression enabled
  still reports smaller disk usage

Add a new _require_disk_usage that quickly probes whether an attempt
to create a sparse 5M file shows as less than 1M usage, while the same
file with -o preallocation=full shows as more than 4M usage without
sync, which should filter out ZFS behavior.  Then use it in various
affected tests.

This does not add the new filter on all tests that Fiona is seeing ZFS
failures on, but only those where I could quickly spot that there is
at least one place where the test depends on the output of 'du -b' or
'stat -c %b'.

ed1c336119 iotests: Improve mirror-sparse on ext4 and xfs
Fiona reported that an ext4 filesystem on top of LVM can sometimes
report over-allocation to du (based on the heuristics the filesystem
is making while observing the contents being mirrored); even though
the contents and actual size matched, about 50% of the time the size
reported by disk_usage was too large by 4k, failing the test.  In
auditing other iotests, this is a common problem we've had to deal
with.

Meanwhile, Markus reported that an xfs filesystem reports disk usage
at a default granularity of 1M (so the sparse file occupies 3M, since
it has just over 2M data).

f8d41d0511 qapi: make s390x specific CPU commands unconditionally available
This removes the TARGET_S390X and CONFIG_KVM conditions from the
CPU commands that are conceptually specific to s390x. Top level
stubs are provided to cope with non-s390x targets, or builds
without KVM.

The removal of CONFIG_KVM is justified by the fact there is no
conceptual difference between running 'qemu-system-s390x -accel tcg'
on a build with and without KVM built-in, so apps only using TCG
can't rely on the CONFIG_KVM in the schema.

a3e7f6d05d test/qtest/hace: Adjust test address range for AST1030 due to SRAM limitations
The digest_addr is set to "src_addr + 0x1000000", where src_addr is the DRAM
base address. However, the value 0x1000000 (16MB) is too large because the
AST1030 does not support DRAM, and its SRAM size is only 768KB.

A range size of 0x10000 (64KB) is sufficient for HACE test cases, as the test
vector size does not exceed 64KB.

Updates:
1. Direct Access Mode
Update digest_addr to "src_addr + 0x10000" in the following functions:
aspeed_test_md5
aspeed_test_sha256
aspeed_test_sha512

2. Scatter-Gather (SG) Mode
Update source address for different SG buffer addresses in the following
functions:
src_addr1 = src_addr + 0x10000
src_addr2 = src_addr + 0x20000
src_addr3 = src_addr + 0x30000
digest_addr = src_addr + 0x40000

aspeed_test_sha256_sg
aspeed_test_sha512_sg

3. ACC Mode Update
Update the SG List start address: src_addr + 0x10000
Update the SG List buffer size to 0x30000 (192KB).

buffer_addr = src_addr + 0x10000
digest_addr = src_addr + 0x40000

70985b0ea7 test/qtest: Introduce a new aspeed-hace-utils.c to place common testcases
The test cases for the ASPEED HACE model were originally placed in
aspeed_hace-test.c. However, this test file only supports ARM32. To enable
compatibility with all ASPEED SoCs, including the AST2700, which uses the
AArch64 architecture, this update introduces a new source file,
aspeed-hace-utils.c.

All common APIs and test cases have been moved from aspeed_hace-test.c to
aspeed-hace-utils.c to facilitate reuse across different ASPEED SoCs.
As a result, these test cases can now be reused for AST2700 and future ASPEED
SoC testing.

1bd4237cb1 util/qemu-sockets: Introduce inet socket options controlling TCP keep-alive
With the default TCP stack configuration, it could be even 2 hours
before the connection times out due to the other side not being
reachable. However, in some cases, the application needs to be aware of
a connection issue much sooner.

This is the case, for example, for postcopy live migration. If there is
no traffic from the migration destination guest (server-side) to the
migration source guest (client-side), the destination keeps waiting for
pages indefinitely and does not switch to the postcopy-paused state.
This can happen, for example, if the destination QEMU instance is
started with the '-S' command line option and the machine is not started
yet, or if the machine is idle and produces no new page faults for
not-yet-migrated pages.

This patch introduces new inet socket parameters that control count,
idle period, and interval of TCP keep-alive packets before the
connection is considered broken. These parameters are available on
systems where the respective TCP socket options are defined, that
includes Linux, Windows, macOS, but not OpenBSD. Additionally, macOS
defines TCP_KEEPIDLE as TCP_KEEPALIVE instead, so the patch supplies its
own definition.

The default value for all is 0, which means the system configuration is
used.

316e8ee8d6 util/qemu-sockets: Refactor inet_parse() to use QemuOpts
Currently, the inet address parser cannot handle multiple options where
one is prefixed with the name of the other. For example, with the
'keep-alive-idle' option added, the current parser cannot parse
'127.0.0.1:5000,keep-alive-idle=60,keep-alive' correctly. Instead, it
fails with "error parsing 'keep-alive' flag '-idle=60,keep-alive'".

To resolve these issues, this patch rewrites the inet address parsing
using the QemuOpts parser, which the inet_parse_flag() function tries to
mimic. This new parser supports all previously supported options and on
top of that the 'numeric' flag is now also supported. The only
difference is, the new parser produces an error if an unknown option is
passed, instead of silently ignoring it.

c0ddcb2cbc tests: Add iotest mirror-sparse for recent patches
Prove that blockdev-mirror can now result in sparse raw destination
files, regardless of whether the source is raw or qcow2.  By making
this a separate test, it was possible to test effects of individual
patches for the various pieces that all have to work together for a
sparse mirror to be successful.

Note that ./check -file produces different job lengths than ./check
-qcow2 (the test uses a filter to normalize); that's because when
deciding how much of the image to be mirrored, the code looks at how
much of the source image was allocated (for qcow2, this is only the
written clusters; for raw, it is the entire file).  But the important
part is that the destination file ends up smaller than 3M, rather than
the 20M it used to be before this patch series.

181a63667a mirror: Skip pre-zeroing destination if it is already zero
When doing a sync=full mirroring, we can skip pre-zeroing the
destination if it already reads as zeroes and we are not also trying
to punch holes due to detect-zeroes.  With this patch, there are fewer
scenarios that have to pass in an explicit target-is-zero, while still
resulting in a sparse destination remaining sparse.

A later patch will then further improve things to skip writing to the
destination for parts of the image where the source is zero; but even
with just this patch, it is possible to see a difference for any
source that does not report itself as fully allocated, coupled with a
destination BDS that can quickly report that it already reads as zero.
(For a source that reports as fully allocated, such as a file, the
rest of mirror_dirty_init() still sets the entire dirty bitmap to
true, so even though we avoided the pre-zeroing, we are not yet
avoiding all redundant I/O).

Iotest 194 detects the difference made by this patch: for a file
source (where block status reports the entire image as allocated, and
therefore we end up writing zeroes everywhere in the destination
anyways), the job length remains the same.  But for a qcow2 source and
a destination that reads as all zeroes, the dirty bitmap changes to
just tracking the allocated portions of the source, which results in
faster completion and smaller job statistics.  For the test to pass
with both ./check -file and -qcow2, a new python filter is needed to
mask out the now-varying job amounts (this matches the shell filters
_filter_block_job_{offset,len} in common.filter).  A later test will
also be added which further validates expected sparseness, so it does
not matter that 194 is no longer explicitly looking at how many bytes
were copied.

253b43a290 mirror: Drop redundant zero_target parameter
The two callers to a mirror job (drive-mirror and blockdev-mirror) set
zero_target precisely when sync mode == FULL, with the one exception
that drive-mirror skips zeroing the target if it was newly created and
reads as zero.  But given the previous patch, that exception is
equally captured by target_is_zero.

Meanwhile, there is another slight wrinkle, fortunately caught by
iotest 185: if the caller uses "sync":"top" but the source has no
backing file, the code in blockdev.c was changing sync to be FULL, but
only after it had set zero_target=false.  In mirror.c, prior to recent
patches, this didn't matter: the only places that inspected sync were
setting is_none_mode (both TOP and FULL had set that to false), and
mirror_start() setting base = mode == MIRROR_SYNC_MODE_TOP ?
bdrv_backing_chain_next(bs) : NULL.  But now that we are passing sync
around, the slammed sync mode would result in a new pre-zeroing pass
even when the user had passed "sync":"top" in an effort to skip
pre-zeroing.  Fortunately, the assignment of base when bs has no
backing chain still works out to NULL if we don't slam things.  So
with the forced change of sync ripped out of blockdev.c, the sync mode
is passed through the full callstack unmolested, and we can now
reliably reconstruct the same settings as what used to be passed in by
zero_target=false, without the redundant parameter.
