9f17bfdab4 target/s390x: support SHA-512 extensions
In order to fully support MSA_EXT_5, we have to support the SHA-512
special instructions. So implement those.

The implementation began as something TweetNacl-like, and then was
adjusted to be useful here. It's not very beautiful, but it is quite
short and compact, which is what we're going for.

ab9ccfa850 linux-user/host/s390: Add vector instructions to host_signal_write()
The new noexec test fails on s390x with "unexpected SEGV". This test
overwrites code using libc's memcpy(), which uses VSTL instruction.
host_signal_write() does not recognize it, which causes SEGV to be
incorrectly forwarded to the test.

Add all vector instructions that write to memory to
host_signal_write().

d8c2e6f2f6 hcd-ohci: Drop ohci_service_iso_td() if ed->head & OHCI_DPTR_MASK is zero
An abort happens in ohci_frame_boundary() when ohci->done is 0 [1].

``` c
static void ohci_frame_boundary(void *opaque)
{
    // ...
    if (ohci->done_count == 0 && !(ohci->intr_status & OHCI_INTR_WD)) {
        if (!ohci->done)
            abort(); <----------------------------------------- [1]
```

This was reported in https://bugs.launchpad.net/qemu/+bug/1911216/,
https://lists.gnu.org/archive/html/qemu-devel/2021-06/msg03613.html, and
https://gitlab.com/qemu-project/qemu/-/issues/545. I can still reproduce it with
the latest QEMU.

This happends due to crafted ED with putting ISO_TD at physical address 0.

Suppose ed->head & OHCI_DPTR_MASK is 0 [2], and we memset 0 to the phyiscal
memory from 0 to sizeof(ohci_iso_td). Then, starting_frame [3] and frame_count
[4] are both 0. As we can control the value of ohci->frame_number (0 to 0x1f,
suppose 1), we then control the value of relative_frame_number to be 1 [6]. The
control flow goes to [7] where ohci->done is 0. Have returned from
ohci_service_iso_td(), ohci_frame_boundary() will abort() [1].

``` c
static int ohci_service_iso_td(OHCIState *ohci, struct ohci_ed *ed)
{
    // ...
    addr = ed->head & OHCI_DPTR_MASK; // <--------------------- [2]

    if (ohci_read_iso_td(ohci, addr, &iso_td)) {   // <-------- [3]
        // ...

    starting_frame = OHCI_BM(iso_td.flags, TD_SF); // <-------- [4]
    frame_count = OHCI_BM(iso_td.flags, TD_FC);    // <-------- [5]
    relative_frame_number = USUB(ohci->frame_number, starting_frame);
                                                   // <-------- [6]
    if (relative_frame_number < 0) {
        return 1;
    } else if (relative_frame_number > frame_count) {
        // ...
        ohci->done = addr;                         // <-------- [7]
        // ...
    }
```

As only (afaik) a guest root user can manipulate ED, TD and the physical memory,
this assertion failure is not a security bug.

The idea to fix this issue is to drop ohci_service_iso_td() if ed->head &
OHCI_DPTR_MASK is 0, which is similar to the drop operation for
ohci_service_ed_list() when head is 0. Probably, a similar issue is in
ohci_service_td(). I drop ohci_service_td() if ed->head & OHCI_DPTR_MASK is 0.

d18431547f ui/vdagent: fix serial reset of guest agent
In order to reset the guest agent, we send CLOSED & OPENED events.

They are correctly received by the guest kernel. However, they might not
be noticed by the guest agent process, as the IO task (poll() for
example) might be wake up after both CLOSED & OPENED have been
processed.

Wait until the guest agent is disconnected to re-open our side.

bab6a301c5 ui/cocoa: Run qemu_init in the main thread
This work is based on:
https://patchew.org/QEMU/20220317125534.38706-1-philippe.mathieu.daude@gmail.com/

Simplify the initialization dance by running qemu_init() in the main
thread before the Cocoa event loop starts. The secondary thread only
runs only qemu_main_loop() and qemu_cleanup().

This fixes a case where addRemovableDevicesMenuItems() calls
qmp_query_block() while expecting the main thread to still hold
the BQL.

Overriding the code after calling qemu_init() is done by dynamically
replacing a function pointer variable, qemu_main when initializing
ui/cocoa, which unifies the static implementation of main() for
builds with ui/cocoa and ones without ui/cocoa.

d135f78140 linux-user: use 'max' instead of 'qemu32' / 'qemu64' by default
The 'qemu64' CPU model implements the least featureful x86_64 CPU that's
possible. Historically this hasn't been an issue since it was rare for
OS distros to build with a higher mandatory CPU baseline.

With RHEL-9, however, the entire distro is built for the x86_64-v2 ABI
baseline:

  https://developers.redhat.com/blog/2021/01/05/building-red-hat-enterprise-linux-9-for-the-x86-64-v2-microarchitecture-level

It is likely that other distros may take similar steps in the not too
distant future. For example, it has been suggested for Fedora on a
number of occasions.

This new baseline is not compatible with the qemu64 CPU model though.
While it is possible to pass a '-cpu xxx' flag to qemu-x86_64, the
usage of QEMU doesn't always allow for this. For example, the args
are typically controlled via binfmt rules that the user has no ability
to change. This impacts users who are trying to use podman on aarch64
platforms, to run containers with x86_64 content. There's no arg to
podman that can be used to change the qemu-x86_64 args, and a non-root
user of podman can not change binfmt rules without elevating privileges:

  https://github.com/containers/podman/issues/15456#issuecomment-1228210973

Changing to the 'max' CPU model gives 'qemu-x86_64' maximum
compatibility with binaries it is likely to encounter in the wild,
and not likely to have a significant downside for existing usage.

Most other architectures already use an 'any' CPU model, which is
often mapped to 'max' (or similar) already, rather than the oldest
possible CPU model.

For the sake of consistency the 'i386' architecture is also changed
from using 'qemu32' to 'max'.

For backward compatibility, g_date_time_get_microsecond should be used
to retrieve subsecond.

In this patch the g_date_time_format() leaves subsecond field as "%06d"
and let next snprintf to format with g_date_time_get_microsecond.

cc3c71e89f configure: Remove use of backtick ... syntax
There's only one place in configure where we use `...` to execute a
command and capture the result.  Switch to $() to match the rest of
the script. This silences a shellcheck warning.

002d8c13df configure: Add './' on front of glob of */config-devices.mak.d
Shellcheck warns that in

the glob might expand to something with a '-' in it, which would
then be misinterpreted as an option to rm. Fix this by adding './'.

64708615e7 configure: Add missing quoting for some easy cases
This commit adds quotes in some places which:
 * are spotted by shellcheck
 * are obviously incorrect
 * are easy to fix just by adding the quotes

It doesn't attempt fix all of the places shellcheck finds errors,
or even all the ones which are easy to fix. It's just a random
sampling which is hopefully easy to review and which cuts
down the size of the problem for next time somebody wants to
try to look at shellcheck errors.

342cf30413 configure: Remove unused python_version variable
Shellcheck correctly reports that we set python_version and never use
it.  This is a leftover from commit f933275789: we used to use
python_version purely to as part of the summary information printed

the information from meson (which looks up the python version
itself). Remove the unused variable.

5e689840a1 io/channel-websock: Replace strlen(const_str) by sizeof(const_str) - 1
The combined_key[... QIO_CHANNEL_WEBSOCK_GUID_LEN ...] array in
qio_channel_websock_handshake_send_res_ok() expands to a call
to strlen(QIO_CHANNEL_WEBSOCK_GUID), and the compiler doesn't
realize the string is const, so consider combined_key[] being
a variable-length array.

To remove the variable-length array, we provide it a hint to
the compiler by using sizeof() - 1 instead of strlen().

895a803ce9 hw/net/lan9118: Signal TSFL_INT flag when TX FIFO reaches specified level
The LAN9118 allows the guest to specify a level for both the TX and
RX FIFOs at which an interrupt will be generated.  We implement the
RSFL_INT interrupt for the RX FIFO but are missing the handling of
the equivalent TSFL_INT for the TX FIFO.  Add the missing test to set
the interrupt if the TX FIFO has exceeded the guest-specified level.

This flag is required for Micrium lan911x ethernet driver to work.
