We already got a global function called id_generate() to create unique
IDs within QEMU. Let's use it in the network subsytem, too, instead of
inventing our own ID scheme here.

Supporting '0x20M' looks odd, particularly since we have a 'B' suffix
that is ambiguous for bytes, as well as a less-frequently-used 'E'
suffix for extremely large exibytes. In practice, people using hex
inputs are specifying values in bytes (and would have written
0x2000000, or possibly relied on default_suffix in the case of
qemu_strtosz_MiB), and the use of scaling suffixes makes the most
sense for inputs in decimal (where the user would write 32M). But
rather than outright dropping support for hex-with-suffix, let's
follow our deprecation policy. Sadly, since qemu_strtosz() does not
have an Err** parameter, and plumbing that in would be a much larger
task, we instead go with just directly emitting the deprecation
warning to stderr.

We have multiple clients of qemu_strtosz (qemu-io, the opts visitor,
the keyval visitor), and it gets annoying that edge-case testing is
impacted by implicit rounding to 53 bits of precision due to parsing
with strtod(). As an example posted by Rich Jones:
$ nbdkit memory $(( 2**63 - 2**30 )) --run \
'build/qemu-io -f raw "$uri" -c "w -P 3 $(( 2**63 - 2**30 - 512 )) 512" '
write failed: Input/output error
because 9223372035781033472 got rounded to 0x7fffffffc0000000 which is
out of bounds.
It is also worth noting that our existing parser, by virtue of using
strtod(), accepts decimal AND hex numbers, even though test-cutils
previously lacked any coverage of the latter until the previous patch.
We do have existing clients that expect a hex parse to work (for
example, iotest 33 using qemu-io -c "write -P 0xa 0x200 0x400"), but
strtod() parses "08" as 8 rather than as an invalid octal number, so
we know there are no clients that depend on octal. Our use of
strtod() also means that "0x1.8k" would actually parse as 1536 (the
fraction is 8/16), rather than 1843 (if the fraction were 8/10); but
as this was not covered in the testsuite, I have no qualms forbidding
hex fractions as invalid, so this patch declares that the use of
fractions is only supported with decimal input, and enhances the
testsuite to document that.
Our previous use of strtod() meant that -1 parsed as a negative; now
that we parse with strtoull(), negative values can wrap around modulo
2^64, so we have to explicitly check whether the user passed in a '-';
and make it consistent to also reject '-0'. This has the minor effect
of treating negative values as EINVAL (with no change to endptr)
rather than ERANGE (with endptr advanced to what was parsed), visible
in the updated iotest output.
We also had no testsuite coverage of "1.1e0k", which happened to parse
under strtod() but is unlikely to occur in practice; as long as we are
making things more robust, it is easy enough to reject the use of
exponents in a strtod parse.
The fix is done by breaking the parse into an integer prefix (no loss
in precision), rejecting negative values (since we can no longer rely
on strtod() to do that), determining if a decimal or hexadecimal parse
was intended (with the new restriction that a fractional hex parse is
not allowed), and where appropriate, using a floating point fractional
parse (where we also scan to reject use of exponents in the fraction).
The bulk of the patch is then updates to the testsuite to match our
new precision, as well as adding new cases we reject (whether they
were rejected or inadvertently accepted before).

The "delay" option was a hack that was introduced to allow writing "nodelay".
We are adding a "nodelay" option to be used as "nodelay=on", so recommend it
instead of "delay".
This is quite ugly, but a proper deprecation of "delay"
cannot be done if QEMU starts suggesting it. Since it's the
only case I opted for this very much ad-hoc patch.

There is currently no way to open(O_RDONLY) and mmap(PROT_READ) when
creating a memory region from a file. This functionality is needed since
the underlying host file may not allow writing.
Add a bool readonly argument to memory_region_init_ram_from_file() and
the APIs it calls.
Extend memory_region_init_ram_from_file() rather than introducing a
memory_region_init_rom_from_file() API so that callers can easily make a
choice between read/write and read-only at runtime without calling
different APIs.
No new RAMBlock flag is introduced for read-only because it's unclear
whether RAMBlocks need to know that they are read-only. Pass a bool
readonly argument instead.
Both of these design decisions can be changed in the future. It just
seemed like the simplest approach to me.

The -msg timestamp=on|off option controls whether a timestamp is printed
with error_report() messages. The "-msg" name suggests that this option
has a wider effect than just error_report(). The next patch extends it
to the 'log' trace backend, so rename the variable from
error_with_timestamp to message_with_timestamp.

Disposition (action) for any given signal is global for the process.
When two threads run coroutine-sigaltstack's qemu_coroutine_new()
concurrently, they may interfere with each other: One of them may revert
the SIGUSR2 handler to SIG_DFL, between the other thread (a) setting up
coroutine_trampoline() as the handler and (b) raising SIGUSR2. That
SIGUSR2 will then terminate the QEMU process abnormally.
We have to ensure that only one thread at a time can modify the
process-global SIGUSR2 handler. To do so, wrap the whole section where
that is done in a mutex.
Alternatively, we could for example have the SIGUSR2 handler always be
coroutine_trampoline(), so there would be no need to invoke sigaction()
in qemu_coroutine_new(). Laszlo has posted a patch to do so here:
https://lists.nongnu.org/archive/html/qemu-devel/2021-01/msg05962.html
However, given that coroutine-sigaltstack is more of a fallback
implementation for platforms that do not support ucontext, that change
may be a bit too invasive to be comfortable with it. The mutex proposed
here may negatively impact performance, but the change is much simpler.

Options such as "server" or "nowait", that are commonly found in -chardev,
are sugar for "server=on" and "wait=off". This is quite surprising and
also does not have any notion of typing attached. It is even possible to
do "-device e1000,noid" and get a device with "id=off".
Deprecate it and print a warning when it is encountered. In general,
this short form for boolean options only seems to be in wide use for
-chardev and -spice.

Right now, help options are parsed normally and then checked
specially in opt_validate, but only if coming from
qemu_opts_parse_noisily. has_help_option does the check on its own.
opt_validate() has two callers: qemu_opt_set(), which passes null and is
therefore unaffected, and opts_do_parse(), which is affected.
opts_do_parse() is called by qemu_opts_do_parse(), which passes null and
is therefore unaffected, and opts_parse().
opts_parse() is called by qemu_opts_parse() and qemu_opts_set_defaults(),
which pass null and are therefore unaffected, and
qemu_opts_parse_noisily().
Move the check from opt_validate to the parsing workhorse of QemuOpts,
get_opt_name_value. This will come in handy in the next patch, which
will raise a warning for "-object memory-backend-ram,share" ("flag" option
with no =on/=off part) but not for "-object memory-backend-ram,help".
As a result:
- opts_parse and opts_do_parse do not return an error anymore
when help is requested; qemu_opts_parse_noisily does not have
to work around that anymore.
- various crazy ways to request help are not recognized anymore:
- "help=..."
- "nohelp" (sugar for "help=off")
- "?=..."
- "no?" (sugar for "?=off")
- "help" would be recognized as help request even if there is a (foolishly
named) parameter "help". No such parameters exist, though.

i.e. they don't need an id. Sometimes its presence is ignored
(e.g. when using qemu_opts_foreach), sometimes all the options
with the id are skipped, sometimes only the first option on the
command line is considered. -boot does two different things
depending on who's looking at the options.
With this patch we just forbid id on merge-lists QemuOptsLists; if the
command line still works, it has the same semantics as before.
qemu_opts_create's fail_if_exists parameter is now unnecessary:
- it is unused if id is NULL
- opts_parse only passes false if reached from qemu_opts_set_defaults,
in which case this patch enforces that id must be NULL
- other callers that can pass a non-NULL id always set it to true
Assert that it is true in the only case where "fail_if_exists" matters,
i.e. "id && !lists->merge_lists". This means that if an id is present,
duplicates are always forbidden, which was already the status quo.
Discounting the case that aborts as it's not user-controlled (it's
"just" a matter of inspecting qemu_opts_create callers), the paths
through qemu_opts_create can be summarized as:
- merge_lists = true: singleton opts with NULL id; non-NULL id fails
- merge_lists = false: always return new opts; non-NULL id fails if dup

The yank feature allows to recover from hanging qemu by "yanking"
at various parts. Other qemu systems can register themselves and

Low-level fd users from QEMU use aio_set_fd_handler(), which handles
event registration with the main loop; qemu_fd_register() is only
needed together with the main loop's poll notifiers, of which SLIRP
is the only user.
This removes a dependency from oslib-win32.c to main-loop.c.

LLVM/Clang, supports runtime checks for forward-edge Control-Flow
Integrity (CFI).
CFI on indirect function calls (cfi-icall) ensures that, in indirect
function calls, the function called is of the right signature for the
pointer type defined at compile time.
For this check to work, the code must always respect the function
signature when using function pointer, the function must be defined
at compile time, and be compiled with link-time optimization.
This rules out, for example, shared libraries that are dynamically loaded
(given that functions are not known at compile time), and code that is
dynamically generated at run-time.
This patch:
1) Introduces the CONFIG_CFI flag to support cfi in QEMU
2) Introduces a decorator to allow the definition of "sensitive"
functions, where a non-instrumented function may be called at runtime
through a pointer. The decorator will take care of disabling cfi-icall
checks on such functions, when cfi is enabled.
3) Marks functions currently in QEMU that exhibit such behavior,
in particular:
- The function in TCG that calls pre-compiled TBs
- The function in TCI that interprets instructions
- Functions in the plugin infrastructures that jump to callbacks
- Functions in util that directly call a signal handler

QString supports modifying its string, but it's quite limited: you can

string, never for modifying it later.
Change keyval_parse_one() to do build the initial string with GString.

Anywhere we create a list of just one item or by prepending items
(typically because order doesn't matter), we can use
QAPI_LIST_PREPEND(). But places where we must keep the list in order
by appending remain open-coded until later patches.
Note that as a side effect, this also performs a cleanup of two minor
issues in qga/commands-posix.c: the old code was performing
new = g_malloc0(sizeof(*ret));
which 1) is confusing because you have to verify whether 'new' and
'ret' are variables with the same type, and 2) would conflict with C++
compilation (not an actual problem for this file, but makes
copy-and-paste harder).

A QemuOptsList can be of one of two kinds: either it is pre-validated, or
it accepts any key and validation happens somewhere else (typically in
a Visitor or against a list of QOM properties). opts_accepts_any
returns true if a QemuOpts instance was created from a QemuOptsList of
the latter kind, but there is no function to do the check on a QemuOptsList.
Since this property comes from the QemuOptsList and almost all callers of
opts_accepts_any use opts->list anyway, modify the function to accept
QemuOptsList.

qemu_opts_set is used to create default network backends and to
parse sugar options -kernel, -initrd, -append, -bios and -dtb.
These are very different uses:
I would *expect* a function named qemu_opts_set to set an option in a
merge-lists QemuOptsList, such as -kernel, and possibly to set an option
in a non-merge-lists QemuOptsList with non-NULL id, similar to -set.
However, it wouldn't *work* to use qemu_opts_set for the latter
because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists
QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the
(QemuOptsList, id) pair already exists) are debatable.
On the other hand, I would not expect qemu_opts_set to create a
non-merge-lists QemuOpts with a single option; which it does, though.
For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set
hardly adds value over qemu_opts_parse. It does skip some parsing and
unescaping, but that's not needed when creating default network
backends.
So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList
if id is non-NULL, and it's mostly pointless if id is NULL. My
solution to keeping the API as simple as possible is to limit
qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we
don't want comma-unescaping for -kernel) *and* has sane semantics.
Network backend creation is switched to qemu_opts_parse.
qemu_opts_set is now only used on merge-lists QemuOptsList... except
in the testcase, which is changed to use a merge-list QemuOptsList.
With this change we can also remove the id parameter. With the
parameter always NULL, we know that qemu_opts_create cannot fail
and can pass &error_abort to it.

Currently, when using "nvme://" for a block device, like
-drive file=nvme://0000:01:00.0/1,if=none,id=drive0 \
-device virtio-blk,drive=drive0 \
VFIO may pin all guest memory, and discarding of RAM no longer works as
expected. I was able to reproduce this easily with my
01:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd
NVMe SSD Controller SM981/PM981/PM983
Similar to common VFIO, we have to disable it, making sure that:
a) virtio-balloon won't discard any memory ("silently disabled")
b) virtio-mem and nvme:// run mutually exclusive
