Provide initial support for SEV-ES. This includes creating a function to
indicate the guest is an SEV-ES guest (which will return false until all
support is in place), performing the proper SEV initialization and
ensuring that the guest CPU state is measured as part of the launch.

If the gpa isn't specified, it's value is extracted from the OVMF
properties table located below the reset vector (and if this doesn't
exist, an error is returned). OVMF has defined the GUID for the SEV
secret area as 4c2eb361-7d9b-4cc3-8081-127c90d3d294 and the format of
the <data> is: <base>|<size> where both are uint32_t. We extract
<base> and use it as the gpa for the injection.
Note: it is expected that the injected secret will also be GUID
described but since qemu can't interpret it, the format is left
undefined here.

OVMF is developing a mechanism for depositing a GUIDed table just
below the known location of the reset vector. The table goes
backwards in memory so all entries are of the form
<data>|len|<GUID>
Where <data> is arbtrary size and type, <len> is a uint16_t and
describes the entire length of the entry from the beginning of the
data to the end of the guid.
The foot of the table is of this form and <len> for this case
describes the entire size of the table. The table foot GUID is
defined by OVMF as 96b582de-1fb2-45f7-baea-a366c55a082d and if the
table is present this GUID is just below the reset vector, 48 bytes
before the end of the firmware file.
Add a parser for the ovmf reset block which takes a copy of the block,
if the table foot guid is found, minus the footer and a function for
later traversal to return the data area of any specified GUIDs.

In commit e2bbc4eaa7 we changed the QAPI modules to name the built-in
module "./builtin" rather than None, but forgot to update the Sphinx
plugin. The effect of this was that when the plugin generated a dependency
file it was including a bogus dependency on a non-existent file named
"builtin", which meant that ninja would run Sphinx and rebuild all
the documentation every time even if nothing had changed.
Update the plugin to use the new name of the builtin module.

Before this patch, monitor_qmp_dispatcher_co() used to check whether
shutdown is requested only when it would have to wait for new requests.
If there were still some queued requests, it would try to execute all of
them before shutting down.
This can be surprising when the queued QMP commands take long or hang
because Ctrl-C may not actually exit QEMU as soon as possible.
Change monitor_qmp_dispatcher_co() so that it additionally checks
whether shutdown is request before it gets a new request from the queue.

Commit 357bda95 already tried to fix the order in monitor_cleanup() by
moving shutdown of the dispatcher coroutine further to the start.
However, it didn't go far enough:
iothread_stop() makes sure that all pending work (bottom halves) in the
AioContext of the monitor iothread is completed. iothread_destroy()
depends on this and fails an assertion if there is still a pending BH.
While the dispatcher coroutine is running, it will try to resume the
monitor after taking a request out of the queue, which involves a BH.
The dispatcher is run until it terminates in the AIO_WAIT_WHILE() loop.
However, adding new BHs between iothread_stop() and iothread_destroy()
is forbidden.
Fix this by stopping the dispatcher first before shutting down the other
parts of the monitor. This means we can now receive requests that aren't
handled any more when QEMU is shutting down, but this is unlikely to be
a problem for QMP clients.

In IO thread when do bdrv_mirror_top_pwritev, the job is NULL, and stop field
is false, this means the MirrorBDSOpaque "s" object has not been initialized
yet, and this object is initialized by block_job_create(), but the initialize
process is stuck in acquiring the lock.
In this situation, IO thread come to bdrv_mirror_top_pwritev(),which means that
mirror-top node is already inserted into block graph, but its bs->opaque->job
is not initialized.
The root cause is that qemu main thread do release/acquire when hold the lock,
at the same time, IO thread get the lock after release stage, and the crash
occured.
Actually, in this situation, job->job.aio_context will not equal to
qemu_get_aio_context(), and will be the same as bs->aio_context,
thus, no need to release the lock, becasue bdrv_root_attach_child()
will not change the context.
This patch fix this issue.

To disallow certain refcount_bits values, some _unsupported_imgopts
invocations look like "refcount_bits=1[^0-9]", i.e. they match an
integer boundary with [^0-9]. This expression does not match the end of
the string, though, so it breaks down when refcount_bits is the last
option (which it tends to be after the rewrite of the check script in
Python).
Those invocations could use \b or \> instead, but those are not
portable. They could use something like \([^0-9]\|$\), but that would
be cumbersome. To make it simple and keep the existing invocations
working, just let _unsupported_imgopts match the regex against $IMGOPTS
plus a trailing space.

currently uses. As all x86 jobs are being moved to GitLab CI too,
there is no compelling reason to update the travis container. It
is simpler to just remove it.

Travis-CI seems to have enforced memory limit on containers,

Until we have a replacement for this job on Gitlab-CI, disable

Shippable is about to sunset in May 2021 [1] and we had already moved
a chunk of the crossbuilds to GitLab. We already cross build
mips-softmmu targets since:
6bcb5fc0f7 ("gitlab-ci: Add cross-compiling build tests")
and x86 is very well covered.

The sizeof(struct ifreq) is 40 for 64 bit and 32 for 32 bit architectures.
This structure contains a union of other structures, of which struct ifmap
is the biggest for 64 bit architectures. Calling ioclt(…, SIOCGIFCONF, …)
fills a struct sockaddr of that union, and do_ioctl_ifconf() only considered
that struct sockaddr for the size of the union, which has the same size as
struct ifmap on 32 bit architectures. So do_ioctl_ifconf() assumed a wrong
size of 32 for struct ifreq instead of the correct size of 40 on 64 bit
architectures.
The fix makes do_ioctl_ifconf() handle struct ifmap as the biggest part of
the union, treating struct ifreq with the correct size.

If mremap() is called without the MREMAP_MAYMOVE flag with a start address
just before the end of memory (reserved_va) where new_size would exceed
it (and GUEST_ADDR_MAX), the assert(end - 1 <= GUEST_ADDR_MAX) in
page_set_flags() would trigger.
Add an extra guard to the guest_range_valid() checks to prevent this and
avoid asserting binaries when reserved_va is set.
This meant a bug I was seeing locally now gives the same behaviour
regardless of whether reserved_va is set or not.

Some ELF binaries encode the .bss section as an extension of the data
ones by setting the segment p_memsz > p_filesz. Some other binaries take
a different route and encode it as a stand-alone PT_LOAD segment with
p_filesz = 0 and p_memsz > 0.
Both the encodings are actually correct per ELF specification but the
ELF loader had some troubles in handling the former: with the old logic
it was very likely to get Qemu to crash in zero_bss when trying to
access unmapped memory.
zero_bss isn't meant to allocate whole zero-filled segments but to
"complete" a previously mapped segment with the needed zero bits.
The fix is pretty simple, if the segment is completely zero-filled we
simply allocate one or more pages (according to p_memsz) and avoid
calling zero_bss altogether.

On the hppa target userspace binaries may call signalfd4() and
eventfd2() with an old TARGET_O_NONBLOCK value of 000200004 instead of
000200000 for the "mask" syscall parameter, in which case the current
emulation doesn't handle the translation to the native O_NONBLOCK value
correctly.
The 0x04 bit is not masked out before the new O_NONBLOCK bit is set and
as such when calling the native syscall errors out with EINVAL.
Fix this by introducing TARGET_O_NONBLOCK_MASK which is used to mask off
all possible bits. This define defaults to TARGET_O_NONBLOCK when not
defined otherwise, so for all other targets the implementation will
behave as before.
This patch needs to be applied on top of my previous two patches.
Bug was found and patch was verified by using qemu-hppa as debian buildd
server on x86_64.

Historically the parisc linux port tried to be compatible with HP-UX
userspace and as such defined the O_NONBLOCK constant to 0200004 to
emulate separate NDELAY & NONBLOCK values.
Since parisc was the only Linux platform which had two bits set, this
produced various userspace issues. Finally it was decided to drop the
(never completed) HP-UX compatibilty, which is why O_NONBLOCK was
changed upstream to only have one bit set in future with this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=75ae04206a4d0e4f541c1d692b7febd1c0fdb814

When mapping the host waitid status to the target status we previously
just used decoding information in the status value. This doesn't follow
what the waitid documentation describes, which instead suggests using
the si_code value for the decoding. This results in the incorrect values
seen when calling waitid. This is especially apparent on RV32 where all
wait calls use waitid (see the bug case).
This patch just passes the waitid status directly back to the guest.
