Before this change, the code signed during the build was installed
directly.
However, the signature gets invalidated because meson modifies the code
to fix dynamic library install names during the install process.
It also prevents meson to strip the code because the pre-signed file is
not marked as an executable (although it is somehow able to perform the
modification described above).
With this change, the unsigned code will be installed and modified by
meson first, and a script signs it later.

With --enable-fuzzing, QEMU_CFLAGS include -fsanitize=fuzzer-no-link.
This should allow us to build non-fuzzer binaries using objects
instrumented for fuzzing. However, to do that, we also need to link with
-fsanitize=fuzzer-no-link. We were not doing that.

From: Hannes Reinecke <hare@suse.de>
The current code sets an infinite timeout on SG_IO requests,
causing the guest to stall if the host experiences a frame
loss.
This patch adds an 'io_timeout' parameter for SCSIDevice to
make the SG_IO timeout configurable, and also shortens the
default timeout to 30 seconds to avoid infinite stalls.

'enospc' is the default for -drive, but qemu allows user to set
drive option werror. If werror of scsi-generic is set to 'report'
by user, qemu will not allow vm to start.
This patch allow user to set werror as 'report' for scsi-generic.

If virtio_scsi_dataplane_start fails, there is a small window when it drops the
aio lock (in aio_wait_bh_oneshot) and the dataplane's AIO handler can
still run during that window.
This is done after the dataplane was marked as fenced, thus we use this flag
to avoid it doing any IO.

When requested to ignore errors, just do nothing and let the
request complete normally. This means that the request will
be accounted correctly.
This is what commit 40dce4ee61 ("scsi-disk: fix rerror/werror=ignore",
2018-10-19) was supposed to do:

The new function is an extension of the switch statement in scsi-disk.c
which also includes the errno cases only found in sg_io_sense_from_errno.
This allows us to consolidate the errno handling.
Extracted from a patch by Hannes Reinecke <hare@suse.de>.

Instead of fishing it from *r->status, just pass the SCSI status
as a positive value of the second parameter and an errno as a
negative value.

Right now, recoverable sense values are only passed directly to the
guest only for rerror=report. However, when rerror/werror are 'stop'
we still don't want the host to be involved on every UNIT ATTENTION
(especially considered that the QMP event will not have enough information
to act on the report).

The command complete callback has a SCSIRequest as the first argument,
and the status field of that structure is identical to the 'status'
argument. So drop the argument from the callback.

This patch checks that ioc is not null before
using it in tcp socket tcp_chr_add_watch function.
The failure occurs in replay mode of the execution,
when monitor and serial port are tcp servers,
and there are no clients connected to them:
-monitor tcp:127.0.0.1:8081,server,nowait
-serial tcp:127.0.0.1:8082,server,nowait

Bus lock debug exception is a feature that can notify the kernel by
generate an #DB trap after the instruction acquires a bus lock when
CPL>0. This allows the kernel to enforce user application throttling or
mitigations.
This feature is enumerated via CPUID.(EAX=7,ECX=0).ECX[bit 24].

The functionality of -writeconfig is limited and the code
does not even try to detect cases where it prints incorrect
syntax (for example if values have a quote in them, since
qemu_config_parse does not support any kind of escaping)
so remove it.

Didn't really forget; being pretty sure that there's no usage in the
wild and having good reasons to remove the code, giving a firm removal
date should encourage people to speak up sooner rather than later.

Second thoughts after agreeing to change something are okay. Keeping
them for yourself not so much, because it deprives your reviewers of a
chance to raise further points.
In this case, the point I didn't make because I wanted to reach
agreement on contents before nitpicking form: you're not using
warn_report() the way it wants to be used:
/*
* Print a warning message to current monitor if we have one, else to stderr.
* Format arguments like sprintf(). The resulting message should be a
---> * single phrase, with no newline or trailing punctuation.
* Prepend the current location and append a newline.
*/
void warn_report(const char *fmt, ...)
Please tidy up.

I knew about the rules for no newline or trailing punctuation, but I
didn't remember the other. I can certainly respin, that said:
- the comment should say "sentence", not "phrase". For example "a
single phrase" is a single phrase, while "the resulting message should
be a single phrase" is a single sentence.
- I'm not sure how to interpret the rule above. First of all, the
sentence mixes part that are mandatory part ("no newline", checked by
checkpatch.pl) is mixed with the style guide ("no trailing punctuation"
and "a single sentence"). Second, whether a single sentence is better
often depends on the case. For example, comparing these four:
WARNING: -writeconfig foo: -writeconfig is deprecated. It will go away
in QEMU 6.2 with no replacement
WARNING: -writeconfig foo: -writeconfig is deprecated and will go away
in QEMU 6.2 with no replacement
WARNING: -writeconfig foo: -writeconfig is deprecated; it will go away
in QEMU 6.2 with no replacement
WARNING: -writeconfig foo: -writeconfig is deprecated
WARNING: -writeconfig foo: it will go away in QEMU 6.2 with no replacement
The first one is what was in this patch.
The second does sound fine to me and it's probably what I'll use in v2,
with or without the "in QEMU 6.2" part. However some could consider it
to be worse style due to the longer sentence.
The third one is playing with the rules; a semicolon would be separating
two sentences. However usage of the semicolon is quite common in error
messages, so maybe it would be good too?
The last one also complies, but it is not clear what "it" refers to so
it seems to be the worst in this case. In other cases it's the obvious
choice, and we even have an API for it (error_append_hint... however it
doesn't play well with error_fatal which I'm otherwise a big fan of).
In this case, not so much.
Paolo

I avoided "sentence", because good error messages aren't always
grammatically complete sentences. My use of "phrase" may well be wrong.
I tried! Patches welcome :)
Dicking around on the web, I just found
https://www.postgres-xl.org/documentation/error-style-guide.html
Drop the Postgres-specific parts, and what's left is pretty close to my
thoughts on error message style.

Semicolons can be okay, as long the resulting message is still short.
Still short:
warning: -writeconfig foo: -writeconfig is deprecated without replacement
warning: -writeconfig foo: option is deprecated; there is no replacement
No longer short:
warning: -writeconfig foo: -writeconfig is deprecated; it will go away in QEMU 6.2 with no replacement
There is no need to squeeze all the information into the "primary" error
message! That one should state what's wrong *concisely*. If you feel
you should explain further, or would like to advise on what could be
done to fix the problem, a separate "hint" message often reads better
than overloading the primary message with information.
When reporting to the user, use error_report() / warn_report() for the
"primary", and error_printf() for the "hint".
When setting an Error, use error_setg() for the "primary", and
error_append_hint() for the "hint". error_report_err() will then use
error_report() and error_printf() correctly.

Use of error_append_hint() requires ERRP_GUARD(). Without ERRP_GUARD(),
the hint indeed gets lost when errp == &error_fatal.
Properly guarded, we could have something like
warning: -writeconfig foo: option -writeconfig is deprecated
This option will go away with no replacement.
I'm glad you like &error_fatal, too! I have had to defend it a few
times :)

Hmm I don't know. I like the brevity, but I find it to be less
user-friendly. And the "it" and "this option" sound wrong on a separate
line. Maybe it's just me.

Hi,
Sorry, I'm coming very late[1] to the discussion. Will there be a
replacement for '-readconfig'?
I agree with Gerd's comment[2] in the last year's thread (I missed to
notice at that time) about '-readconfig' being useful. I'm familiar
with least one hosting provider who uses[3] '-readconfig'. And I've
also used it for small snippets myself. I understand, these simple
use-cases doesn't make it right to keep it. :-)
I'm not saying "don't deprecate '-readconfig'", but just noting its
usefulness, even in its current form. So I'm just curious if there's
be a suggested replacement. Even if it means: "use libvirt; or use your
own bespoke scripts".

-readconfig is not being deprecated, there will be some code new to
integrate it with the changes I'm planning to option parsing.
