Thomas Huth bf22f15114 tests/qtest: Fence the tests that need xlnx-zcu102 with CONFIG_XLNX_ZYNQMP_ARM
The 'xlnx-can-test' and the 'fuzz-xlnx-dp-test' need the "xlnx-zcu102"
machine and thus should only be built and run if CONFIG_XLNX_ZYNQMP_ARM
is enabled.

Thomas Huth a9697d0947 tests/qtest: Run the PPC 32-bit tests with the 64-bit target binary, too
The ppc64 target is a superset of the 32-bit target, so we should
include the tests here, too. This used to be done in the past already,
but it got lost during the conversion to meson.

Yang Zhong 4755927ae1 numa: Support SGX numa in the monitor and Libvirt interfaces
Add the SGXEPCSection list into SGXInfo to show the multiple
SGX EPC sections detailed info, not the total size like before.
This patch can enable numa support for 'info sgx' command and
QMP interfaces. The new interfaces show each EPC section info
in one numa node. Libvirt can use QMP interface to get the
detailed host SGX EPC capabilities to decide how to allocate
host EPC sections to guest.

 SGX1 support: enabled

The basic SGX did not enable numa for SGX EPC sections, which
result in all EPC sections located in numa node 0. This patch

Maxim Levitsky ecd39d620b gdbstub: reject unsupported flags in handle_set_qemu_sstep
handle_query_qemu_sstepbits is reporting NOIRQ and NOTIMER bits
even if they are not supported (as is the case with record/replay).
Instead, store the supported singlestep flags and reject
any unsupported bits in handle_set_qemu_sstep.  This removes
the need for the get_sstep_flags() wrapper.

While at it, move the variables in GDBState, instead of using
global variables.

Stefan Hajnoczi cf4fbc3030 block/nvme: fix infinite loop in nvme_free_req_queue_cb()
When the request free list is exhausted the coroutine waits on
q->free_req_queue for the next free request. Whenever a request is
completed a BH is scheduled to invoke nvme_free_req_queue_cb() and wake
up waiting coroutines.

1. nvme_get_free_req() waits for a free request:

    while (q->free_req_head == -1) {
        ...
            trace_nvme_free_req_queue_wait(q->s, q->index);
            qemu_co_queue_wait(&q->free_req_queue, &q->lock);
        ...
    }

2. nvme_free_req_queue_cb() wakes up the coroutine:

    while (qemu_co_enter_next(&q->free_req_queue, &q->lock)) {
       ^--- infinite loop when free_req_head == -1
    }

nvme_free_req_queue_cb() and the coroutine form an infinite loop when
q->free_req_head == -1. Fix this by checking q->free_req_head in
nvme_free_req_queue_cb(). If the free request list is exhausted, don't
wake waiting coroutines. Eventually an in-flight request will complete
and the BH will be scheduled again, guaranteeing forward progress.

2021-12-07 09:28:11 -08:00
Damien Hedde 2958e5150d gicv3: fix ICH_MISR's LRENP computation
According to the "Arm Generic Interrupt Controller Architecture
Specification GIC architecture version 3 and 4" (version G: page 345
for aarch64 or 509 for aarch32):
LRENP bit of ICH_MISR is set when ICH_HCR.LRENPIE==1 and
ICH_HCR.EOIcount is non-zero.

When only LRENPIE was set (and EOI count was zero), the LRENP bit was
wrongly set and MISR value was wrong.

As an additional consequence, if an hypervisor set ICH_HCR.LRENPIE,
the maintenance interrupt was constantly fired. It happens since patch
9cee1efe92 ("hw/intc: Set GIC maintenance interrupt level to only 0 or 1")
which fixed another bug about maintenance interrupt (most significant
bits of misr, including this one, were ignored in the interrupt trigger).

Richard Henderson b9537d5904 tcg/arm: Reduce vector alignment requirement for NEON
With arm32, the ABI gives us 8-byte alignment for the stack.
While it's possible to realign the stack to provide 16-byte alignment,
it's far easier to simply not encode 16-byte alignment in the
VLD1 and VST1 instructions that we emit.

Remove the assertion in temp_allocate_frame, limit natural alignment
to the provided stack alignment, and add a comment.

Philippe Mathieu-Daudé 1ab95af033 hw/block/fdc: Kludge missing floppy drive to fix CVE-2021-20196
Guest might select another drive on the bus by setting the
DRIVE_SEL bit of the DIGITAL OUTPUT REGISTER (DOR).
The current controller model doesn't expect a BlockBackend
to be NULL. A simple way to fix CVE-2021-20196 is to create
an empty BlockBackend when it is missing. All further
accesses will be safely handled, and the controller state
machines keep behaving correctly.
