Makefile: Install qemu-img and qemu-nbd man pages only if built
When splitting openSUSE's qemu and qemu-linux-user packages we noticed
that for linux-user-only builds unrelated man pages got installed.
It's surely possible to delete them before packaging, but not installing

tap: fix NULL dereference when passing invalid parameters to tap
This patch forbid the following invalid parameters to tap:

2) vhostfds were specified but fds were not specified

For 1 and 2, net_init_tap_one() will still pass NULL as vhostfdname to

Also remove the unnecessary has_fd check.

create qemu_openpty_raw() helper function and move it to a separate file
In two places qemu uses openpty() which is very system-dependent,
and in both places the pty is switched to raw mode as well.
Make a wrapper function which does both steps, and move all the
system-dependent complexity into a separate file, together
with static/local implementations of openpty() and cfmakeraw()
from qemu-char.c.
It is in a separate file, not part of oslib-posix.c, because
openpty() often resides in -lutil which is not linked to
every program qemu builds.
This change removes #including of <pty.h>, <termios.h>
and other rather specific system headers out of qemu-common.h,
which isn't a place for such specific headers really.
This version has been verified to build correctly on Linux,
OpenBSD, FreeBSD and OpenIndiana. On the latter it lets qemu
to be built with gtk gui which were not possible there due to
missing openpty() and cfmakeraw().

blockdev: reset werror/rerror on drive_del
Paolo Bonzini <pbonzini@redhat.com> suggested the following test case:

qemu-system-x86_64 -enable-kvm -m 1024 \
-drive if=none,cache=none,file=test.img,id=foo,werror=stop,rerror=stop
-device virtio-blk-pci,drive=foo,id=virtio0,addr=4
2. Hot unplug the device:
(qemu) drive_del foo
3. Select the first boot menu entry
Without this patch the guest pauses due to ENOMEDIUM. The guest is
stuck in a continuous pause loop since the I/O request is retried and
fails immediately again when the guest is resumed.
With this patch the error is reported to the guest.
Note that this scenario actually happens sometimes during libvirt disk
hot unplug, where device_del is followed by drive_del. I/O may still be
submitted to the drive after drive_del if the guest does not process the
PCI hot unplug notification.

qemu-char: don't issue CHR_EVENT_OPEN in a BH
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET,
and it was issued as a bottom-half:
86e94dea5b740dad65446c857f6959eae43e0ba6
Which we basically used to print out a greeting/prompt for the
monitor.
AFAICT the only reason this was ever done in a BH was because in
some cases we'd modify the chr_write handler for a new chardev
backend *after* the site where we issued the reset (see:
86e94d:qemu_chr_open_stdio())
At some point this event was renamed to CHR_EVENT_OPENED, and we've
maintained the use of this BH ever since.
However, due to
9f939df955a4152aad69a19a77e0898631bb2c18, we schedule
the BH via g_idle_add(), which is causing events to sometimes be
delivered after we've already begun processing data from backends,
leading to:
known bugs:
QMP:
session negotation resets with OPENED event, in some cases this
is causing new sessions to get sporadically reset
potential bugs:
hw/usb/redirect.c:
can_read handler checks for dev->parser != NULL, which may be
true if CLOSED BH has not been executed yet. In the past, OPENED
quiesced outstanding CLOSED events prior to us reading client
data. If it's delayed, our check may allow reads to occur even
though we haven't processed the OPENED event yet, and when we
do finally get the OPENED event, our state may get reset.
qtest.c:
can begin session before OPENED event is processed, leading to
a spurious reset of the system and irq_levels
gdbstub.c:
may start a gdb session prior to the machine being paused
To fix these, let's just drop the BH.
Since the initial reasoning for using it still applies to an extent,
work around that by deferring the delivery of CHR_EVENT_OPENED until
after the chardevs have been fully initialized, toward the end of
qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This
defers delivery long enough that we can be assured a CharDriverState
is fully initialized before CHR_EVENT_OPENED is sent.
Also, rather than requiring each chardev to do an explicit open, do it
automatically, and allow the small few who don't desire such behavior to
suppress the OPENED-on-init behavior by setting a 'explicit_be_open'
flag.
We additionally add missing OPENED events for stdio backends on w32,
which were previously not being issued, causing us to not recieve the
banner and initial prompts for qmp/hmp.

However, as we use a uint64_t to store the resulting address, that mask

reserved bits but also selects the XD bit (execute-disable) which

rtl8139: flush queued packets when RxBufPtr is written
Net queues support efficient "receive disable". For example, tap's file
descriptor will not be polled while its peer has receive disabled. This
saves CPU cycles for needlessly copying and then dropping packets which
the peer cannot receive.
rtl8139 is missing the qemu_flush_queued_packets() call that wakes the
queue up when receive becomes possible again.
As a result, the Windows 7 guest driver reaches a state where the
rtl8139 cannot receive packets. The driver has actually refilled the
receive buffer but we never resume reception.
The bug can be reproduced by running a large FTP 'get' inside a Windows
7 guest:
$ qemu -netdev tap,id=tap0,...
-device rtl8139,netdev=tap0
The Linux guest driver does not trigger the bug, probably due to a
different buffer management strategy.

Revert "versatile_pci: Put the host bridge PCI device at slot 29"
This reverts commit
5f37ef92b7690423ac6311d3c597e182fc5f8fe6.
It turns out that some kernels incorrectly depend on the
old QEMU behaviour of not putting the host PCI bridge device
where the hardware puts it, because they use a swizzling IRQ
mapping which is incorrect but happens to match up with old
broken QEMU when the slot number mod 4 is zero. Since we
start PCI devices at 11, if we put the host bridge at 29
then the first real PCI device goes at 11 and doesn't work.
Not putting the host bridge at 29 means it defaults to 11,
so the first real PCI device is at 12 and works.
Since continuing with the old behaviour doesn't cause problems
for kernels which do work with hardware, the simplest fix for
this is to revert the change.

configure: Detect uuid on MacOSX (fixes compile failure)
Commit
7791dba3ec broke compilation on MacOSX, because it introduced
a new include of util.h. On MacOSX this includes pwd.h which in turn
includes the system uuid/uuid.h, which causes a compile failure if
QEMU was configured without CONFIG_UUID due to a conflict between
the system header and our fallback versions:
block/vdi.c:124:20: error: static declaration of 'uuid_generate'
follows non-static declaration
static inline void uuid_generate(uuid_t out)

/usr/include/uuid/uuid.h:63:6: note: previous declaration is here
void uuid_generate(uuid_t out);

Fix this breakage by improving configure's check for uuid to work on
MacOSX (where there is no need to link in a separate libuuid).
Note that if the user explicitly runs configure with '--disable-uuid'
on MacOSX then QEMU will fail to compile.

qcow2: Catch some L1 table index overflows
This catches the situation that is described in the bug report at
https://bugs.launchpad.net/qemu/+bug/865518 and goes like this:
$ qemu-img create -f qcow2 huge.qcow2 $((1024*1024))T
Formatting 'huge.qcow2', fmt=qcow2 size=
1152921504606846976 encryption=off cluster_size=65536 lazy_refcounts=off
$ qemu-io /tmp/huge.qcow2 -c "write $((1024*1024*1024*1024*1024*1024 - 1024)) 512"
Segmentation fault
With this patch applied the segfault will be avoided, however the case
will still fail, though gracefully:
$ qemu-img create -f qcow2 /tmp/huge.qcow2 $((1024*1024))T
Formatting 'huge.qcow2', fmt=qcow2 size=
1152921504606846976 encryption=off cluster_size=65536 lazy_refcounts=off
qemu-img: The image size is too large for file format 'qcow2'
Note that even long before these overflow checks kick in, you get
insanely high memory usage (up to INT_MAX * sizeof(uint64_t) = 16 GB for
the L1 table), so with somewhat smaller image sizes you'll probably see
qemu aborting for a failed g_malloc().
If you need huge image sizes, you should increase the cluster size to
the maximum of 2 MB in order to get higher limits.

This patch adds a small typename cache to ObjectClass. This allows
caching positive casts within each ObjectClass. Benchmarking a
PPC workload provided by Aurelien, this patch eliminates every
single g_hash_table_lookup() happening during the benchmark (which
was about 2 million per-second).
With this patch applied, I get exactly the same performance (within

qxl: Call spice_qxl_driver_unload from qxl_enter_vga_mode
With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to
know what part of the primary to use for each monitor. If the guest driver
does not support this, the server sends messages to the client for a
single monitor spanning the entire primary.
As soon as the guest calls spice_qxl_monitors_config_async once, the server
sets the red_worker driver_has_monitors_config flag and stops doing this.
This is a problem when the driver gets unloaded, for example after a reboot
or when switching to a text vc with usermode mode-setting under Linux.
To reproduce this start a multi-mon capable Linux guest which uses
usermode mode-setting and then once X has started switch to a text vc. Note
how the client window does not only not resize, if you try to resize it
manually you always keep blackborders since the aspect is wrong.
This patch calls a new spice-server method called spice_qxl_driver_unload
which clears the driver_has_monitors_config flag inside the server, thereby
fixing this.
