08712fcb85 net: Track netdevs in NetClientState rather than QemuOpt
As mentioned in the previous patch, our use of QemuOpt group "netdev"
has two purposes: collect the CLI arguments, and serve as a witness
for monitor hotplug actions.  As the latter didn't use anything but an
id, it felt rather unclean to have to touch QemuOpts at all when going
through QMP, so let's instead track things with a bool field in
NetClientState.

db2a380c84 net: Complete qapi-fication of netdev_add
We've had all the required pieces for doing a type-safe representation
of netdev_add as a flat union for quite some time now (since
0e55c381f6 in v2.7.0, released in 2016), but did not make the final
switch to using it because of concern about whether a command-line
regression in accepting "1" in place of 1 for integer arguments would
be problematic.  Back then, we did not have the deprecation cycle to
allow us to make progress.  But now that we have waited so long, other
problems have crept in: for example, our desire to add
qemu-storage-daemon is hampered by the inability to express net
objects, and we are unable to introspect what we actually accept.
Additionally, our round-trip through QemuOpts silently eats any
argument that expands to an array, rendering dnssearch, hostfwd, and
guestfwd useless through QMP:

{"execute": "netdev_add", "arguments": { "id": "netdev0",
  "type": "user", "dnssearch": [
    { "str": "8.8.8.8" }, { "str": "8.8.4.4" }
  ]}}

So without further ado, let's turn on proper QAPI.  netdev_add() was a
trivial wrapper around net_client_init(), which did a few steps prior
to calling net_client_init1(); with this patch, we now skip directly
to net_client_init1().  In addition to fixing array parameters, the
following additional differences occur:

-  {"execute": "netdev_add", "arguments": {"type": "help"}}
no longer attempts to print help to stdout and exit.  Bug fix, broken
in 547203ead4 'net: List available netdevs with "-netdev help"',
v2.12.0.

-  {"execute": "netdev_add", "arguments': {... "ipv6-net": "..." }}
no longer attempts to desugar the undocumented ipv6-net magic string
into the proper "ipv6-prefix" and "ipv6-prefixlen".  Undocumented
misfeature, introduced in commit 7aac531ef2 "qapi-schema, qemu-options
& slirp: Adding Qemu options for IPv6 addresses", v2.6.0.

-  {'execute':'netdev_add',
     'arguments':{'id':'net2', 'type':'hubport', 'hubid':"2"}}
   {"error": {"class": "GenericError", "desc": "Invalid parameter type for 'hubid', expected: integer"}}
Used to succeed: since our command line treats everything as strings,
our not-so-round-trip conversion from QAPI -> QemuOpts -> QAPI lost
the original typing and turned everything into a string; now that we
skip the QemuOpts, the JSON input has to match the exact QAPI type.
But this stricter QMP is desirable, and introspection is sufficient
for any affected applications to make sure they use it correctly.

In qmp_netdev_add(), we still have to create a QemuOpts object so that
qmp_netdev_del() will be able to remove a hotplugged network device;
but the opts->head remains empty since we now manage all parsing
through the QAPI object rather than QemuOpts; a separate patch will
address the abuse of QemuOpts as a witness for whether a
NetClientState is a netdev.  In the meantime, our argument that we are
okay requires auditing all uses of option group "netdev":

- qemu_netdev_opts: option group definition, empty .desc[]
- CLI (CLI netdev parsing ends before monitors start, so while
  monitors can mess with CLI netdevs, CLI cannot mess with
  monitor netdevs):
  - main() case QEMU_OPTION_netdev: store CLI definition
  - main() case QEMU_OPTION_readconfig, case QEMU_OPTION_writeconfig:
  similar, dealing only with CLI
  - net_init_clients(): Pass CLI to net_client_init()
- Monitor:
  - hmp_netdev_add(): straightforward parse into net_client_init()
  - qmp_netdev_add(): subject of this patch, used to add full
  object to option group, now just adds bare-bones id
  - qmp_netdev_del(), netdev_del_completion(): check the option group
  solely for id, as a 'is this a netdev' predicate

df4097aeaf qapi: Mark deprecated QMP parts with feature 'deprecated'
Add feature 'deprecated' to the deprecated QMP commands, so their
deprecation becomes visible in output of query-qmp-schema.  Looks like
this:

    {"name": "query-cpus",
     "ret-type": "[164]",
     "meta-type": "command",
     "arg-type": "0",
---> "features": ["deprecated"]}

Management applications could conceivably use this for static
checking.

The deprecated commands are change, cpu-add, migrate-set-cache-size,
migrate_set_downtime, migrate_set_speed, query-cpus, query-events,
query-migrate-cache-size.

The deprecated command arguments are block-commit arguments @base and
@top, and block_set_io_throttle, blockdev-change-medium,
blockdev-close-tray, blockdev-open-tray, eject argument @device.

The deprecated command results are query-cpus-fast result @arch,
query-block result @dirty-bitmaps, query-named-block-nodes result
@encryption_key_missing and result @dirty-bitmaps's member @status.
Same for query-block result @inserted, which mirrors
query-named-block-nodes.

a62c61747f qapi: Simplify how qmp_dispatch() gets the request ID
We convert the request object to a QDict twice: first in
qmp_dispatch() to get the request ID, and then again in
qmp_dispatch_check_obj(), which converts to QDict, then checks and
returns it.  We can't get the request ID from the latter, because it's
null when the qdict flunks the checks.

Move the checked conversion to QDict from qmp_dispatch_check_obj() to
qmp_dispatch(), and drop the duplicate there.

3bc2609d47 gdbstub: Fix single-step issue by confirming 'vContSupported+' feature to gdb
Recently when debugging an arm32 system on qemu, I found sometimes the
single-step command (stepi) is not working. This can be reproduced by
below steps:
 1) start qemu-system-arm -s -S .. and wait for gdb connection.
 2) start gdb and connect to qemu. In my case, gdb gets a wrong value
    (0x60) for PC, which is an another bug.
 3) After connected, type 'stepi' and expect it will stop at next ins.

But, it has never stopped. This because:
 1) We doesn't report ‘vContSupported’ feature to gdb explicitly and gdb
    think we do not support it. In this case, gdb use a software breakpoint
    to emulate single-step.
 2) Since gdb gets a wrong initial value of PC, then gdb inserts a
    breakpoint to wrong place (PC+4).

Not only for the arm target, Philippe has also encountered this on MIPS.
Probably gdb has different assumption for different architectures.

Since we do support ‘vContSupported’ query command, so let's tell gdb that
we support it.

Before this change, gdb send below 'Z0' packet to implement single-step:
gdb_handle_packet: Z0,4,4

After this change, gdb send "vCont;s.." which is expected:
gdb_handle_packet: vCont?
put_packet: vCont;c;C;s;S
gdb_handle_packet: vCont;s:p1.1;c:p1.-1

d116e813a5 gdbstub: change GDBState.last_packet to GByteArray
Remove the packet size upper limit by using a GByteArray
instead of a statically allocated array for last_packet.
Thus we can now send big packets.

Also remove the last_packet_len field and use last_packet->len
instead.

2b6d6371a9 tests/tcg/aarch64: add SVE iotcl test
This is a fairly bare-bones test of setting the various vector sizes
for SVE which will only fail if the PR_SVE_SET_VL can't reduce the
user-space vector length by powers of 2.

However we will also be able to use it in a future test which
exercises the GDB stub.

976b99b6ec target/arm: don't bother with id_aa64pfr0_read for USER_ONLY
For system emulation we need to check the state of the GIC before we
report the value. However this isn't relevant to exporting of the
value to linux-user and indeed breaks the exported value as set by
modify_arm_cp_regs.

7b6a2198e7 target/arm: default SVE length to 64 bytes for linux-user
The Linux kernel chooses the default of 64 bytes for SVE registers on
the basis that it is the largest size on known hardware that won't
grow the signal frame. We still honour the sve-max-vq property and
userspace can expand the number of lanes by calling PR_SVE_SET_VL.

This should not make any difference to SVE enabled software as the SVE
is of course vector length agnostic.
