2013-04-15qdev: Fix QOM unrealize behaviorAndreas Färber
Since commit 249d41720b7dfbb5951b430b9eefdbee7464f515 (qdev: Prepare "realized" property) setting realized = true would register the device's VMStateDescription, but realized = false would not unregister it. Fix that. Moving the code from unparenting also revealed that we were calling DeviceClass::init through DeviceClass::realize as interim solution but DeviceClass::exit still at unparenting time with a realized check. Make this symmetrical by implementing DeviceClass::unrealize to call it, while we're setting realized = false in the unparenting path. The only other unrealize user is mac_nvram, which can safely override it. Thus, mark DeviceClass::exit as obsolete, new devices should implement DeviceClass::unrealize instead.

2013-04-15Add -f FMT / --format FMT arg to qemu-nbdDaniel P. Berrange
Currently the qemu-nbd program will auto-detect the format of any disk it is given. This behaviour is known to be insecure. For example, if qemu-nbd initially exposes a 'raw' file to an unprivileged app, and that app runs 'qemu-img create -f qcow2 -o backing_file=/etc/shadow /dev/nbd0' then the next time the app is started, the qemu-nbd will now detect it as a 'qcow2' file and expose /etc/shadow to the unprivileged app. The only way to avoid this is to explicitly tell qemu-nbd what disk format to use on the command line, completely disabling auto-detection. This patch adds a '-f' / '--format' arg for this purpose, mirroring what is already available via qemu-img and qemu commands. qemu-nbd --format raw -p 9000 evil.img will now always use raw, regardless of what format 'evil.img' looks like it contains Signed-off-by: Daniel P.

2013-04-15tcg-ppc64: Handle deposit of zeroRichard Henderson
The TCG optimizer does great work when inserting constants, being able to fold the open-coded deposit expansion to just an AND or an OR. Avoid a bit the regression caused by having the deposit opcode by expanding deposit of zero as an AND.

2013-04-15qemu-char: another io_add_watch_poll fixPaolo Bonzini
After attaching the source, we have to remove the reference we hold to it, because we do not hold anymore a pointer to the source. If we do not do this, removing the source will not finalize it and will not drop the "real" I/O watch source. This showed up when backporting the new flow control patches to older versions of QEMU that still used select. The whole select then failed with EBADF (poll instead will reporting POLLNVAL on a single pollfd) and QEMU froze.

2013-04-15fpu: Correct edgecase in float64_muladdPeter Maydell
In handling float64_muladd, if we end up doing a subtraction of the product and c, and the 128 bit result of this subtraction happens to have its most significant bit in bit 63, we weren't handling this correctly when attempting to normalize to put the most significant bit into bit 126. We would end up doing a right shift by a negative number (undefined behaviour in C) so at best we would return an incorrect result to the guest. MSB in bit 63 has to be handled as a special case separately from MSB in 0..62 and MSB in 63..126. (MSB in 127 is not possible.)
