5809ac5709 target/arm: Replace sentinels with ARRAY_SIZE in cpregs.h
Remove a possible source of error by removing REGINFO_SENTINEL
and using ARRAY_SIZE (convinently hidden inside a macro) to
find the end of the set of regs being registered or modified.

The space saved by not having the extra array element reduces
the executable's .data.rel.ro section by about 9k.

a81d8d4a72 vhost-user: Don't pass file descriptor for VHOST_USER_REM_MEM_REG
The spec clarifies now that QEMU should not send a file descriptor in a
request to remove a memory region. Change it accordingly.

For libvhost-user, this is a bug fix that makes it compatible with
rust-vmm's implementation that doesn't send a file descriptor. Keep
accepting, but ignoring a file descriptor for compatibility with older
QEMU versions.

ff5927baa7 util: rename qemu_*block() socket functions
The qemu_*block() functions are meant to be be used with sockets (the
win32 implementation expects SOCKET)

Over time, those functions where used with Win32 SOCKET or
file-descriptors interchangeably. But for portability, they must only be
used with socket-like file-descriptors. FDs can use
g_unix_set_fd_nonblocking() instead.

Rename the functions with "socket" in the name to prevent bad usages.

This is effectively reverting commit f9e8cacc55 ("oslib-posix:
rename socket_set_nonblock() to qemu_set_nonblock()").

2ec063788e hw/gpio/aspeed_gpio: Fix QOM pin property
I was setting gpioV4-7 to "1110" using the QOM pin property handler and
noticed that lowering gpioV7 was inadvertently lowering gpioV4-6 too.

    (qemu) qom-set /machine/soc/gpio gpioV4 true
    (qemu) qom-set /machine/soc/gpio gpioV5 true
    (qemu) qom-set /machine/soc/gpio gpioV6 true
    (qemu) qom-get /machine/soc/gpio gpioV4
    true
    (qemu) qom-set /machine/soc/gpio gpioV7 false
    (qemu) qom-get /machine/soc/gpio gpioV4
    false

An expression in aspeed_gpio_set_pin_level was using a logical NOT
operator instead of a bitwise NOT operator:

    value &= !pin_mask;

The original author probably intended to make a bitwise NOT expression
"~", but mistakenly used a logical NOT operator "!" instead. Some
programming languages like Rust use "!" for both purposes.

5cd7d8564a aspeed/hace: Support AST2600 HACE
The aspeed ast2600 accumulative mode is described in datasheet
ast2600v10.pdf section 25.6.4:
 1. Allocating and initiating accumulative hash digest write buffer
    with initial state.
    * Since QEMU crypto/hash api doesn't provide the API to set initial
      state of hash library, and the initial state is already set by
      crypto library (gcrypt/glib/...), so skip this step.
 2. Calculating accumulative hash digest.
    (a) When receiving the last accumulative data, software need to add
        padding message at the end of the accumulative data. Padding
        message described in specific of MD5, SHA-1, SHA224, SHA256,
        SHA512, SHA512/224, SHA512/256.
        * Since the crypto library (gcrypt/glib) already pad the

9ea3164611 9pfs: fix removing non-existent POSIX ACL xattr on macOS host
When mapped POSIX ACL is used, we are ignoring errors when trying
to remove a POSIX ACL xattr that does not exist. On Linux hosts we
would get ENODATA in such cases, on macOS hosts however we get
ENOATTR instead.

As we can be sure that ENOATTR is defined as being identical on Linux
hosts (at least by qemu/xattr.h), it is safe to fix this issue by
simply comparing against ENOATTR instead of ENODATA.

This patch fixes e.g. a command on Linux guest like:

  cp --preserve=mode old new

951fe2f89f 9pfs: fix wrong errno being sent to Linux client on macOS host
Linux and macOS only share some errno definitions with equal macro
name and value. In fact most mappings for errno are completely
different on the two systems.

This patch converts some important errno values from macOS host to
corresponding Linux errno values before eventually sending such error
codes along with 'Rlerror' replies (if 9p2000.L is used that is). Not
having translated errnos before violated the 9p2000.L protocol spec,
which says:

  "
  size[4] Rlerror tag[2] ecode[4]

  ... ecode is a numerical Linux errno.
  "

  https://github.com/chaos/diod/wiki/protocol#lerror----return-error-code

This patch fixes a bunch of misbehaviours when running a Linux client
on macOS host. For instance this patch fixes:

  mount -t 9p -o posixacl ...

on Linux guest if security_mode=mapped was used for 9p server, which
refused to mount successfully, because macOS returned ENOATTR==93
when client tried to retrieve POSIX ACL xattrs, because errno 93
is defined as EPROTONOSUPPORT==93 on Linux, so Linux client believed
that xattrs were not supported by filesystem on host in general.

e5c88e2264 9pfs: fix wrong encoding of rdev field in Rgetattr on macOS
The 'rdev' field in 9p reponse 'Rgetattr' is of type dev_t,
which is actually a system dependant type and therefore both the
size and encoding of dev_t differ between macOS and Linux.

So far we have sent 'rdev' to guest in host's dev_t format as-is,
which caused devices to appear with wrong device numbers on
guests running on macOS hosts, eventually leading to various
misbehaviours on guest in conjunction with device files.

This patch fixes this issue by converting the device number from
host's dev_t format to Linux dev_t format. As 9p request
'Tgettattr' is exclusive to protocol version 9p2000.L, it should
be fair to assume that 'rdev' field is assumed to be in Linux dev_t
format by client as well.

f8e7163d9e hw/arm/smmuv3: Advertise support for SMMUv3.2-BBML2
The Arm SMMUv3 includes an optional feature equivalent to the CPU
FEAT_BBM, which permits an OS to switch a range of memory between
"covered by a huge page" and "covered by a sequence of normal pages"
without having to engage in the traditional 'break-before-make'
dance. (This is particularly important for the SMMU, because devices
performing I/O through an SMMU are less likely to be able to cope with
the window in the sequence where an access results in a translation
fault.)  The SMMU spec explicitly notes that one of the valid ways to
be a BBM level 2 compliant implementation is:
 * if there are multiple entries in the TLB for an address,
   choose one of them and use it, ignoring the others

Our SMMU TLB implementation (unlike our CPU TLB) does allow multiple
TLB entries for an address, because the translation table level is
part of the SMMUIOTLBKey, and so our IOTLB hashtable can include
entries for the same address where the leaf was at different levels
(i.e. both hugepage and normal page). Our TLB lookup implementation in
smmu_iotlb_lookup() will always find the entry with the lowest level
(i.e. it prefers the hugepage over the normal page) and ignore any
others. TLB invalidation correctly removes all TLB entries matching
the specified address or address range (unless the guest specifies the
leaf level explicitly, in which case it gets what it asked for). So we
can validly advertise support for BBML level 2.

Note that we still can't yet advertise ourselves as an SMMU v3.2,
because v3.2 requires support for the S2FWB feature, which we don't
yet implement.

ced716942a hw/arm/smmuv3: Cache event fault record
The Record bit in the Context Descriptor tells the SMMU to report fault
events to the event queue. Since we don't cache the Record bit at the
moment, access faults from a cached Context Descriptor are never
reported. Store the Record bit in the cached SMMUTransCfg.

215b00a542 meson: remove CONFIG_XEN_PCI_PASSTHROUGH from config-target.h
CONFIG_XEN_PCI_PASSTHROUGH is just a global configuration option;
it is never used in the source files, so there is no need to put
CONFIG_XEN_PCI_PASSTHROUGH in config-target.h or even in config-host.h.

This inaccuracy was copied over from the configure script in commit
8a19980e3f ("configure: move accelerator logic to meson", 2020-10-03).
