Describe flaws in qcow/qcow2 encryption in the docs
The qemu-img.texi / qemu-doc.texi files currently describe the
qcow2/qcow2 encryption thus
"Encryption uses the AES format which is very secure (128 bit
keys). Use a long password (16 characters) to get maximum
protection."
While AES is indeed a strong encryption system, the way that
QCow/QCow2 use it results in a poor/weak encryption system.
Due to the use of predictable IVs, based on the sector number
extended to 128 bits, it is vulnerable to chosen plaintext
attacks which can reveal the existence of encrypted data.
The direct use of the user passphrase as the encryption key
also leads to an inability to change the passphrase of an
image. If passphrase is ever compromised the image data will
all be vulnerable, since it cannot be re-encrypted. The admin
has to clone the image files with a new passphrase and then
use a program like shred to secure erase all the old files.
Recommend against any use of QCow/QCow2 encryption, directing
users to dm-crypt / LUKS which can meet modern cryptography
best practices.

* stefanha/tags/tracing-pull-request:
trace: fix simple trace "disable" keyword
trace: add glib 2.32+ static GMutex support
trace: [simple] Do not include "trace/simple.h" in generated tracer headers
tracing: start trace processing thread in final child process
It made the code more complicated though. During development for life
migration/init/reset etc it turned out that this might cause several
hard to debug programming errors. With the introduction of ioeventfd
(and future irqfd patches) the qemu intercept handlers are no longer
hot-path. And therefore the partial register handling can be
removed to simplify the code.

Merge remote-tracking branch 'mst/tags/for_anthony' into staging
acpi,pci,pc,virtio fixes and enhancements
This includes new unit-tests for acpi by Marcel,
hotplug for pci bridges by myself (piix only so far)
and cpu hotplug for q35.
And a bunch of fixes all over the place as usual.
I included the patch to fix memory alignment for q35
as well - even though it limits 32 bit guests to 3G (they
previously could address more memory with PAE).
To remove the limit, this will have to be fixed in seabios.
I also added self as virtio co-maintainer so I don't need
to troll the list for patches to review.

breaks Xen support in QEMU, in particular the Xen mapcache. The effect
is that one Windows XP installation out of ten would end up with BSOD.
The reason is that after this commit l in address_space_rw can span a
page boundary, however qemu_get_ram_ptr still calls xen_map_cache asking
to map a single page (if block->offset == 0).
Fix the issue by reverting to the previous behaviour: do not return a
length from address_space_translate_internal that can span a page
boundary.
Also in address_space_translate do not ignore the length returned by
address_space_translate_internal.
