The 'Quick Start' section of the userspace emulator documentation is
very old and outdated. In particular:
- it suggests running x86-on-x86 emulation, which is the least
interesting possible use case
- it recommends that users download tarballs of guest binaries
from the QEMU web page which we no longer provide there

We used to make a distinction between 'float64'/'float32' types and

operations to go between them. We've now dropped this distinction as
unnecessary, and the 'float*' types remain primarily for

This means that there's no need for a special gdb_get_float64()

just use gdb_get_reg64().

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:

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.

Choose int return status, because bdrv_replace_node_common() has call
to bdrv_check_update_perm(), which reports int status, which seems
correct to propagate.

[eblake: Adjust test for explicit read_zeroes=False]
Signed-off-by: Eric Blake <eblake@redhat.com>
Bitmap's source persistence is transported over the migration stream and
the destination mirrors it. In some cases the destination might want to
persist bitmaps which are not persistent on the source (e.g. the result
of merging bitmaps from a number of layers on the source when migrating
into a squashed image) but currently it would need to create another set
of persistent bitmaps and merge them.
This patch adds a 'transform' property to the alias map which allows
overriding the persistence of migrated bitmaps both on the source and
destination sides.
