851495571d util/async.c: Forbid negative min/max in aio_context_set_thread_pool_params()
aio_context_set_thread_pool_params() takes two int64_t arguments to
set the minimum and maximum number of threads in the pool.  We do
some bounds checking on these, but we don't catch the case where the
inputs are negative.  This means that later in the function when we
assign these inputs to the AioContext::thread_pool_min and
::thread_pool_max fields, which are of type int, the values might
overflow the smaller type.

A negative number of threads is meaningless, so make
aio_context_set_thread_pool_params() return an error if either min or
max are negative.

029e13a8a5 bsd-user: Misc changes for 9.1 (I hope)
V2: Add missing bsd-user/aarch64/target.h
 
 This patch series includes two main sets of patches. To make it simple to
 review, I've included the changes from my student which the later changes depend
 on. I've included a change from Jessica and Doug as well. I've reviewed them,
 but more eyes never hurt.
 
 I've also included a number of 'touch up' patches needed either to get the
 aarch64 building, or to implmement suggestions from prior review cycles. The
 main one is what's charitably described as a kludge: force aarch64 to use 4k
 pages. The qemu-project (and blitz branch) hasn't had the necessary changes to
 bsd-user needed to support variable page size.
 
 Sorry this is so late... Live has conspired to delay me.

97f7bf113e crypto: propagate errors from TLS session I/O callbacks
GNUTLS doesn't know how to perform I/O on anything other than plain
FDs, so the TLS session provides it with some I/O callbacks. The
GNUTLS API design requires these callbacks to return a unix errno
value, which means we're currently loosing the useful QEMU "Error"
object.

This changes the I/O callbacks in QEMU to stash the "Error" object
in the QCryptoTLSSession class, and fetch it when seeing an I/O
error returned from GNUTLS, thus preserving useful error messages.

57941c9c86 crypto: push error reporting into TLS session I/O APIs
The current TLS session I/O APIs just return a synthetic errno
value on error, which has been translated from a gnutls error
value. This looses a large amount of valuable information that
distinguishes different scenarios.

Pushing population of the "Error *errp" object into the TLS
session I/O APIs gives more detailed error information.

GNUTLS already supports dynamically enabling its logging at runtime by
setting the env var 'GNUTLS_DEBUG_LEVEL=10', so there is no need to
re-invent this logic in QEMU in a way that requires a re-compile.

48fc887436 meson: build chardev trace files when have_block
The QSD depends on chardev code, and is built when have_tools is
true. This means conditionalizing chardev trace on have_system
is wrong, we need have_block which is set have_system || have_tools.

This latent bug was historically harmless because only the spice
chardev included tracing, which wasn't built in a !have_system
scenario.

libgcrypt starts providing correct pkg-config configuration since 1.9,
in parallel with libgcrypt-config. Since 1.11 it may also stop
installing libgcrypt-config in some scenarios. Use the auto method for
detection of libgcrypt, in which meson will try both pkg-config and
libgcrypt-config.

Auto method for libgcrypt is supported by meson since 0.49.0, which is
higher than the version qemu requires.

c9e0b9a59c hw/char/goldfish: Use DMA memory API
Rather than using address_space_rw(..., 0 or 1),
use the simpler DMA memory API which expand to
the same code. This allows removing a cast on
the 'buf' variable which is really const. Since
'buf' is only used in the CMD_READ_BUFFER case,
we can reduce its scope.

2f28f28e74 hw/nubus/virtio-mmio: Fix missing ERRP_GUARD() in realize handler
According to the comment in qapi/error.h, dereferencing @errp requires
ERRP_GUARD():

* = Why, when and how to use ERRP_GUARD() =
*
* Without ERRP_GUARD(), use of the @errp parameter is restricted:
* - It must not be dereferenced, because it may be null.
...
* ERRP_GUARD() lifts these restrictions.
*
* To use ERRP_GUARD(), add it right at the beginning of the function.
* @errp can then be used without worrying about the argument being
* NULL or &error_fatal.
*
* Using it when it's not needed is safe, but please avoid cluttering
* the source with useless code.

In nubus_virtio_mmio_realize(), @errp is dereferenced without
ERRP_GUARD().

Although nubus_virtio_mmio_realize() - as a DeviceClass.realize()
method - is never passed a null @errp argument, it should follow the
rules on @errp usage.  Add the ERRP_GUARD() there.
