xen_disk: mark ioreq as mapped before unmapping in error case
Commit
4472beae modified the semantics of ioreq_{un,}map so that they are
idempotent if called when they're not needed (ie., twice in a row). However,
it neglected to handle the case where batch mapping is not being used (the
default), and one of the grants fails to map. In this case, ioreq_unmap will
be called to unwind and unmap any mappings already performed, but ioreq_unmap
simply returns due to the aforementioned change (the ioreq has not already
been marked as mapped).
The frontend user can therefore force xen_disk to leak grant mappings, a
per-domain limited resource.
Fix by marking the ioreq as mapped before calling ioreq_unmap in this
situation.

hw/9pfs: Fix errno value for xattr functions
If there is no operation driver for the xattr type the
functions return '-1' and set errno to '-EOPNOTSUPP'.
When the calling code sets 'ret = -errno' this turns
into a large positive number.
In Linux 3.11, the kernel has switched to using 9p
version 9p2000.L, instead of 9p2000.u, which enables
support for xattr operations. This on its own is harmless,
but for another change which makes it request the xattr
with a name 'security.capability'.
The result is that the guest sees a succesful return
of 95 bytes of data, instead of a failure with errno
set to 95. Since the kernel expects a maximum of 20
bytes for an xattr return this gets translated to the
unexpected errno ERANGE.
This all means that when running a binary off a 9p fs
in 3.11 kernels you get a fun result of:
# ./date
sh: ./date: Numerical result out of range
The only workaround is to pass 'version=9p2000.u' when
mounting the 9p fs in the guest, to disable all use of
xattrs.

An exception to this rule are multicast sockets where it is sensible to have
multiple sockets listen on the same ip and port and we should set SO_REUSEADDR

gdbstub: call socket_set_fast_reuse instead of setting SO_REUSEADDR

util: add socket_set_fast_reuse function which will replace setting SO_REUSEADDR
If a socket is closed it remains in TIME_WAIT state for some time. On operating
systems using BSD sockets the endpoint of the socket may not be reused while in
this state unless SO_REUSEADDR was set on the socket. On windows on the other
hand the default behaviour is to allow reuse (i.e. identical to SO_REUSEADDR on
other operating systems) and setting SO_REUSEADDR on a socket allows it to be
bound to a endpoint even if the endpoint is already used by another socket
independently of the other sockets state. This can even result in undefined
behaviour.
Many sockets used by QEMU should not block the use of their endpoint after being
closed while they are still in TIME_WAIT state. Currently QEMU sets SO_REUSEADDR
for such sockets, which can lead to problems on Windows. This patch introduces
the function socket_set_fast_reuse that should be used instead of setting
SO_REUSEADDR when fast socket reuse is desired and behaves correctly on all
operating systems.
As a failure of this function can only be caused by bad QEMU internal errors, an
assertion handles these situations. The return value is still passed on, to
minimize changes in client code and prevent unused variable warnings if NDEBUG
is defined.

target-i386: Set model=6 on qemu64 & qemu32 CPU models
There's no Intel CPU with family=6,model=2, and Linux and Windows guests
disable SEP when seeing that combination due to Pentium Pro erratum #82.
In addition to just having SEP ignored by guests, Skype (and maybe other
applications) runs sysenter directly without passing through ntdll on
Windows, and crashes because Windows ignored the SEP CPUID bit.
So, having model > 2 is a better default on qemu64 and qemu32 for two
reasons: making SEP really available for guests, and avoiding crashing
applications that work on bare metal.
model=3 would fix the problem, but it causes CPU enumeration problems
for Windows guests[1]. So let's set model=6, that matches "Athlon
(PM core)" on AMD and "P2 with on-die L2 cache" on Intel and it allows
Windows to use all CPUs as well as fixing sysenter.

Switching the L1 table in memory should be an atomic operation, as far

not a good idea when the old L1 table is no longer valid and the address
to the new one hasn't yet been written into the corresponding

smbios: Make multiple -smbios type= accumulate sanely
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME. If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).
Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME). The others are ignored.
"First one wins, subsequent ones get ignored silently" isn't nice. We
commonly let the last option win. Useful, because it lets you
-readconfig first, then selectively override with command line
options.
Clean up -smbios to work the common way. Accumulate the settings,
with later ones overwriting earlier ones. Put the result into fw_cfg
(no more useless duplicates).
Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

smbios: Improve diagnostics for conflicting entries
We allow either tables or fields for the same type. Makes sense,
because SeaBIOS uses fields only when no tables are present.
We do this by searching the SMBIOS blob for a previously added table
or field. Error messages look like this:
qemu-system-x86_64: -smbios type=1,serial=42: SMBIOS type 1 table already defined, cannot add field
User needs to know that "table" is defined by -smbios file=..., and
"field" by -smbios type=...
Instead of searching the blob, record additions of interest, and check
that. Simpler, and makes better error messages possible:
qemu-system-x86_64: -smbios file=smbios_type_1.bin: Can't mix file= and type= for same type
qemu-system-x86_64: -smbios type=1,serial=42,serial=99: This is the conflicting setting

qemu-iotests: Add basic ability to use binary sample images
For image formats that are not "QEMU native", but supported for
compatibility, it is useful to verify that an image created with
the 'gold standard' native tool can be read / written to successfully
by QEMU.
In addition to testing non-native images, this could also be useful to
test against image files created by older versions of QEMU.
This provides a directory to store small sample images, for use by
scripts in tests/qemu-iotests.
Image files should be compressed with bzip2.
To use a sample image from a bash script, the _use_sample_img function
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
be the decompressed sample image copy. To cleanup, call
_cleanup_test_img as normal.
