link's check callback is supposed to verify/permit setting it,
however currently nothing restricts it from misusing it
and modifying target object from within.
Make sure that readonly semantics are checked by compiler
to prevent callback's misuse.

This check is redundant because it is already performed by the only
caller of dump_exec_info -- the caller was updated by b7da97eef
("monitor: Check whether TCG is enabled before running the "info jit"
code").
Checking twice wouldn't necessarily be too bad, but here the check also
returns with tb_lock held. So we can either do the check before tb_lock is
acquired, or just get rid of it. Given that it is redundant, I am going
for the latter option.

Commit e7b161d573 ("vl: add tcg_enabled() for tcg related code") adds
a check to exit the program when !tcg_enabled() while parsing the -tb-size
flag.
It turns out that when the -tb-size flag is evaluated, tcg_enabled() can
only return 0, since it is set (or not) much later by configure_accelerator().
Fix it by unconditionally exiting if the flag is passed to a QEMU binary
built with !CONFIG_TCG.

The upstream NBD Protocol has defined a new extension to allow
the server to advertise block sizes to the client, as well as
a way for the client to inform the server whether it intends to
obey block sizes.
When using the block layer as the client, we will obey block
sizes; but when used as 'qemu-nbd -c' to hand off to the
kernel nbd module as the client, we are still waiting for the
kernel to implement a way for us to learn if it will honor
block sizes (perhaps by an addition to sysfs, rather than an
ioctl), as well as any way to tell the kernel what additional
block sizes to obey (NBD_SET_BLKSIZE appears to be accurate
for the minimum size, but preferred and maximum sizes would
probably be new ioctl()s), so until then, we need to make our
request for block sizes conditional.
When using ioctl(NBD_SET_BLKSIZE) to hand off to the kernel,
use the minimum block size as the sector size if it is larger
than 512, which also has the nice effect of cooperating with
(non-qemu) servers that don't do read-modify-write when
exposing a block device with 4k sectors; it might also allow
us to visit a file larger than 2T on a 32-bit kernel.

The upstream NBD Protocol has defined a new extension to allow
the server to advertise block sizes to the client, as well as
a way for the client to inform the server that it intends to
obey block sizes.
Thanks to a recent fix (commit df7b97ff), our real minimum
transfer size is always 1 (the block layer takes care of
read-modify-write on our behalf), but we're still more efficient
if we advertise 512 when the client supports it, as follows:
- OPT_INFO, but no NBD_INFO_BLOCK_SIZE: advertise 512, then
fail with NBD_REP_ERR_BLOCK_SIZE_REQD; client is free to try
something else since we don't disconnect
- OPT_INFO with NBD_INFO_BLOCK_SIZE: advertise 512
- OPT_GO, but no NBD_INFO_BLOCK_SIZE: advertise 1
- OPT_GO with NBD_INFO_BLOCK_SIZE: advertise 512
We can also advertise the optimum block size (presumably the
cluster size, when exporting a qcow2 file), and our absolute
maximum transfer size of 32M, to help newer clients avoid
EINVAL failures or abrupt disconnects on oversize requests.
We do not reject clients for using the older NBD_OPT_EXPORT_NAME;
we are no worse off for those clients than we used to be.

NBD_OPT_EXPORT_NAME is lousy: per the NBD protocol, any failure
requires the server to close the connection rather than report an
error to us. Therefore, upstream NBD recently added NBD_OPT_GO as
the improved version of the option that does what we want [1]: it
reports sane errors on failures, and on success provides at least
as much info as NBD_OPT_EXPORT_NAME.
[1] https://github.com/NetworkBlockDevice/nbd/blob/extension-info/doc/proto.md
This is a first cut at use of the information types. Note that we
do not need to use NBD_OPT_INFO, and that use of NBD_OPT_GO means
we no longer have to use NBD_OPT_LIST to learn whether a server
requires TLS (this requires servers that gracefully handle unknown
NBD_OPT, many servers prior to qemu 2.5 were buggy, but I have patched
qemu, upstream nbd, and nbdkit in the meantime, in part because of
interoperability testing with this patch). We still fall back to
NBD_OPT_LIST when NBD_OPT_GO is not supported on the server, as it
is still one last chance for a nicer error message. Later patches
will use further info, like NBD_INFO_BLOCK_SIZE.

This is a first cut at the information types, and only passes the
same information already available through NBD_OPT_LIST and

use of NBD_REP_ERR_BLOCK_SIZE_REQD) are intentionally left for

The NBD Protocol is introducing some additional information
about exports, such as minimum request size and alignment, as
well as an advertised maximum request size. It will be easier
to feed this information back to the block layer if we gather
all the information into a struct, rather than adding yet more
pointer parameters during negotiation.

This defines new QOM object - IOMMUMemoryRegion - with MemoryRegion
as a parent.
This moves IOMMU-related fields from MR to IOMMU MR. However to avoid
dymanic QOM casting in fast path (address_space_translate, etc),
this adds an @is_iommu boolean flag to MR and provides new helper to
do simple cast to IOMMU MR - memory_region_get_iommu. The flag
is set in the instance init callback. This defines
memory_region_is_iommu as memory_region_get_iommu()!=NULL.
This switches MemoryRegion to IOMMUMemoryRegion in most places except
the ones where MemoryRegion may be an alias.

The thread-id of 0 means any CPU but we then ignore the fact we find
the first_cpu in this case who can have an index of 0. Instead of
bailing out just test if we have managed to match up thread-id to a
CPU.
Otherwise you get:
gdb_handle_packet: command='vCont;C04:0;c'
put_packet: reply='E22'
The actual reason for gdb sending vCont;C04:0;c was fixed in a
previous commit where we ensure the first_cpu's tid is correctly
reported to gdb however we should still behave correctly next time it
does send 0.

This was only used by the gdbstub and even then was only being set for
subsequent threads. Rather the continue duplicating the number just
make the gdbstub get the information from TaskState structure.
Now the tid is correctly reported for all threads the bug I was seeing
with "vCont;C04:0;c" packets is fixed as the correct tid is reported
to gdb.
I moved cpu_gdb_index into the gdbstub to facilitate easy access to
the TaskState which is used elsewhere in gdbstub.
To prevent BSD failing to build I've included ts_tid into its
TaskStruct but not populated it - which was the same state as the old
cpu->host_tid. I'll leave it up to the BSD maintainers to actually
populate this properly if they want a working gdbstub with
user-threads.

This patch adds a possibility to change a char device without a frontend
removal.
Ideally, it would have to happen transparently to a frontend, i.e.
frontend would continue its regular operation.
However, backends are not stateless and are set up by the frontends
via qemu_chr_fe_<> functions, and it's not (generally) possible to replay
that setup entirely in a backend code, as different chardevs respond
to the setup calls differently, so do frontends work differently basing
on those setup responses.
Moreover, some frontend can generally get and save the backend pointer
(qemu_chr_fe_get_driver()), and it will become invalid after backend change.
So, a frontend which would like to support chardev hotswap has to register
a "backend change" handler, and redo its backend setup there.

The gen_ prefix is awkward. Generated C should go through cgen()
exactly once (see commit 1f9a7a1). The common way to get this wrong is
passing a foo=gen_foo() keyword argument to mcgen(). I'd like us to
adopt a naming convention where gen_ means "something that's been piped
through cgen(), and thus must not be passed to cgen() or mcgen()".
Requires renaming gen_params(), gen_marshal_proto() and
gen_event_send_proto().

The recent commit b097efc0 used qobject_decref(QOBJECT(E)), even
though we already have QDECREF(E) for that purpose. We can update
our coccinelle script to catch any future relapses; with that in
place, the rest of the patch is generated with:
spatch --sp-file scripts/coccinelle/qobject.cocci \
--macro-file scripts/cocci-macro-file.h --dir . --in-place

Dan's addition of key-secret improvements in commit 29cf9336 was
developed prior to the addition of QDict scalar insertion macros,
but merged after the general cleanup in commit 46f5ac20.
Patch created mechanically by rerunning:
spatch --sp-file scripts/coccinelle/qobject.cocci \
--macro-file scripts/cocci-macro-file.h --dir . --in-place
