Stewart Hildebrand ea358872a6 hw/arm/boot: Increase compliance with kernel arm64 boot protocol
"The Image must be placed text_offset bytes from a 2MB aligned base
address anywhere in usable system RAM and called there."

For the virt board, we write our startup bootloader at the very
bottom of RAM, so that bit can't be used for the image. To avoid
overlap in case the image requests to be loaded at an offset
smaller than our bootloader, we increment the load offset to the
next 2MB.

This fixes a boot failure for Xen AArch64.

Peter Maydell 4be42f4013 target/arm: Report correct syndrome for FP/SIMD traps to Hyp mode
For traps of FP/SIMD instructions to AArch32 Hyp mode, the syndrome
provided in HSR has more information than is reported to AArch64.
Specifically, there are extra fields TA and coproc which indicate
whether the trapped instruction was FP or SIMD. Add this extra
information to the syndromes we construct, and mask it out when
taking the exception to AArch64.

Peter Maydell 2ed08180db target/arm: Get IL bit correct for v7 syndrome values
For the v7 version of the Arm architecture, the IL bit in
syndrome register values where the field is not valid was
defined to be UNK/SBZP. In v8 this is RES1, which is what
QEMU currently implements. Handle the desired v7 behaviour
by squashing the IL bit for the affected cases:
 * EC == EC_UNCATEGORIZED
 * prefetch aborts
 * data aborts where ISV is 0

(The fourth case listed in the v8 Arm ARM DDI 0487C.a in
section G7.2.70, "illegal state exception", can't happen
on a v7 CPU.)

This deals with a corner case noted in a comment.

The HCR_EL2 VI and VF bits are supposed to track whether there is
a pending virtual IRQ or virtual FIQ. For QEMU we store the
pending VIRQ/VFIQ status in cs->interrupt_request, so this means:
 * if the register is read we must get these bit values from

   values back into cs->interrupt_request

Peter Maydell 636540e9c4 target/arm: ISR_EL1 bits track virtual interrupts if IMO/FMO set
The A/I/F bits in ISR_EL1 should track the virtual interrupt
status, not the physical interrupt status, if the associated
HCR_EL2.AMO/IMO/FMO bit is set. Implement this, rather than
always showing the physical interrupt status.

We don't currently implement anything to do with external
aborts, so this applies only to the I and F bits (though it
ought to be possible for the outer guest to present a virtual
external abort to the inner guest, even if QEMU doesn't
emulate physical external aborts, so there is missing
functionality in this area).

Peter Maydell 81e3728407 target/arm: Improve debug logging of AArch32 exception return
For AArch32, exception return happens through certain kinds
of CPSR write. We don't currently have any CPU_LOG_INT logging
of these events (unlike AArch64, where we log in the ERET
instruction). Add some suitable logging.

This will log exception returns like this:
Exception return from AArch32 hyp to usr PC 0x80100374

paralleling the existing logging in the exception_return
helper for AArch64 exception returns:
Exception return from AArch64 EL2 to AArch64 EL0 PC 0x8003045c
Exception return from AArch64 EL2 to AArch32 EL0 PC 0x8003045c

(Note that an AArch32 exception return can only be
AArch32->AArch32, never to AArch64.)

This patch extends the qemu-kvm state sync logic with support for
KVM_GET/SET_VCPU_EVENTS, giving access to yet missing SError exception.
And also it can support the exception state migration.

The SError exception states include SError pending state and ESR value,
the kvm_put/get_vcpu_events() will be called when set or get system
registers. When do migration, if source machine has SError pending,
QEMU will do this migration regardless whether the target machine supports
to specify guest ESR value, because if target machine does not support that,
it can also inject the SError with zero ESR value.

Markus Armbruster 61e9e3cb45 ssi-sd: Make devices picking up backends unavailable with -device
Device models aren't supposed to go on fishing expeditions for
backends.  They should expose suitable properties for the user to set.
For onboard devices, board code sets them.

Device ssi-sd picks up its block backend in its init() method with
drive_get_next() instead.  This mistake is already marked FIXME since
commit af9e40a.

Unset user_creatable to remove the mistake from our external
interface.  Since the SSI bus doesn't support hotplug, only -device
can be affected.  Only certain ARM machines have ssi-sd and provide an
SSI bus for it; this patch breaks -device ssi-sd for these machines.
No actual use of -device ssi-sd is known.

Richard Henderson 3ebee3b191 osdep: Work around MinGW assert
In several places we use assert(FEATURE), and assume that if FEATURE
is disabled, all following code is removed as unreachable.  Which allows
us to compile-out functions that are only present with FEATURE, and
have a link-time failure if the functions remain used.

MinGW does not mark its internal function _assert() as noreturn, so the
compiler cannot see when code is unreachable, which leads to link errors
for this host that are not present elsewhere.

The current build-time failure concerns 62823083b8, but I remember
having seen this same error before.  Fix it once and for all for MinGW.

Fam Zheng 6e157a0339 slirp: Add sanity check for str option length
When user provides a long domainname or hostname that doesn't fit in the
DHCP packet, we mustn't overflow the response packet buffer. Instead,
report errors, following the g_warning() in the slirp->vdnssearch
branch.

Also check the strlen against 256 when initializing slirp, which limit
is also from the protocol where one byte represents the string length.
This gives an early error before the warning which is harder to notice
or diagnose.

Daniel P. Berrangé 64dd2f3b5b crypto: require nettle >= 2.7.1 for building QEMU
nettle 2.7.1 was released in 2013 and all the distros that are build
target platforms for QEMU [1] include it:

  RHEL-7: 2.7.1
  Debian (Stretch): 3.3
  Debian (Jessie): 2.7.1
  OpenBSD (ports): 3.4
  FreeBSD (ports): 3.4
  OpenSUSE Leap 15: 3.4
  Ubuntu (Xenial): 3.2
  macOS (Homebrew): 3.4

Based on this, it is reasonable to require nettle >= 2.7.1 in QEMU
which allows for some conditional version checks in the code to be
removed.

Markus Armbruster da7e92cac9 block: Clean up bdrv_img_create()'s error reporting
bdrv_img_create() takes an Error ** argument and uses it in the
conventional way, except for one place: when qemu_opts_do_parse()
fails, it first reports its error to stderr or the HMP monitor with
error_report_err(), then error_setg()'s a generic error.

When the caller reports that second error similarly, this produces two
consecutive error messages on stderr or the HMP monitor.

When the caller does something else with it, such as send it via QMP,
the first error still goes to stderr or the HMP monitor.  Fortunately,
no such caller exists.

Simply use the first error as is.  Update expected output of
qemu-iotest 049 accordingly.

Markus Armbruster c4f26c9f37 blockdev: Convert drive_new() to Error
Calling error_report() from within a function that takes an Error **
argument is suspicious.  drive_new() calls error_report() even though
it can run within drive_init_func(), which takes an Error ** argument.
drive_init_func()'s caller main(), via qemu_opts_foreach(), is fine
with it, but clean it up anyway:

* Convert drive_new() to Error

* Update add_init_drive() to report the error received from
  drive_new()

* Make main() pass &error_fatal through qemu_opts_foreach(),
  drive_init_func() to drive_new()

* Make default_drive() pass &error_abort through qemu_opts_foreach(),
  drive_init_func() to drive_new()

Markus Armbruster f881ca19f1 vl: Assert drive_new() does not fail in default_drive()
If creating (empty) default drives fails, it's a bug.  Therefore,
assert() is more appropriate than exit(1).

Markus Armbruster b836723dfe fsdev: Clean up error reporting in qemu_fsdev_add()
Calling error_report() from within a function that takes an Error **
argument is suspicious.  qemu_fsdev_add() does that, and its caller
fsdev_init_func() then fails without setting an error.  Its caller
main(), via qemu_opts_foreach(), is fine with it, but clean it up
