When accessing the dispatch pointer in an AddressSpace within an RCU
critical section we should always use atomic_rcu_read(). Fix an
access within memory_region_section_get_iotlb() which was incorrectly
doing a direct pointer access.

Commit 812c1057 introduced HUP detection on unix and tcp sockets prior
to a read in tcp_chr_read. This unfortunately broke CloudStack 4.2
which relied on the old behaviour where data on a socket was readable
even if a HUP was present.
A working solution is to properly check the return values from recv,
handling a closed socket once there is no more data to read.
Also enable polling for G_IO_NVAL to ensure the callback is called
for all possible events as these should now be possible to handle
with the improved error detection.

The current unit test only verifies the encryption API,
resulting in us missing a recently introduced bug in the
decryption API from commit d3462e3. It was fortunately
later discovered & fixed by commit bd09594, thanks to the
QEMU I/O tests for qcow2 encryption, but we should really
detect this directly in the crypto unit tests. Also remove
an accidental debug message and simplify some asserts.

This is a guest-triggerable buffer overflow present in QEMU 2.2.0
and newer. scsi_cdb_length returns -1 as an error value, but the
caller does not check it.
Luckily, the massive overflow means that QEMU will just SIGSEGV,
making the impact much smaller.

Currently, scsi_get_configuration always returns a current
profile (DVD or CD), even when there is actually no media present.
By comparison, ide/atapi uses a default profile of 0 (MMC_PROFILE_NONE)
for this case and checks for tray_open, so let's do the same for scsi.
This fixes a problem I'm seeing with Fedora 22 guests where systemd
cdrom_id fails to unmount after a QEMU-initiated eject against a
scsi cdrom device because it believes the media is still present
(but unreadable).

For a board that has multiple framebuffer devices, both of them
might want to use DIRTY_MEMORY_VGA on the same memory region.
The lack of reference counting in memory_region_set_log makes
this very awkward to implement.

The MemoryRegionSection contains enough information to access the
RAM region underlying the framebuffer, and can be cached inside the
display device.
By doing this, the new framebuffer_update_memory_section function can
enable dirty memory logging on the relevant RAM region. The function
must be called whenever the stride or base of the framebuffer changes;
a simple way to cover these cases is to call it on every full frame
invalidation, which is a rare case.
framebuffer_update_display now works entirely on a MemoryRegionSection,
without going through cpu_physical_memory_map/unmap.

So this patch was not actually causing the problem, merely exposing a
latent bug. I've just sent a fix for the root cause, which you can
queue before the test case patch addition to preserve bisectability.

Yes, that was likely.

I'll prepare another pull request next week for these two patches if you
still haven't sorted out signed tags. In the meanwhile, there was
another problem reported at
https://lists.gnu.org/archive/html/qemu-devel/2015-07/msg02170.html.
Basically, with --enable-static the tools failed to link on Ubuntu.

Ok, I'll investigate that and try to send another patch before your
