migration: Read JSON VM description on incoming migration
One of the really nice things about the VM description format is that it goes
over the wire when live migration is happening. Unfortunately QEMU today closes
any socket once it sees VM_EOF coming, so we never give the VMDESC the chance to
actually land on the wire.
This patch makes QEMU read the description as well. This way we ensure that
anything wire tapping us in between will get the chance to also interpret the
stream.
Along the way we also fix virt tests that assume that number_bytes_sent on the
sender side is equal to number_bytes_read which was true before the VMDESC
patches and is true again with this patch.

linux-user: Access correct register for get/set_tls syscalls on ARM TZ CPUs
When support was added for TrustZone to ARM CPU emulation, we failed
to correctly update the support for the linux-user implementation of
the get/set_tls syscalls. This meant that accesses to the TPIDRURO
register via the syscalls were always using the non-secure copy of
the register even if native MRC/MCR accesses were using the secure
register. This inconsistency caused most binaries to segfault on startup
if the CPU type was explicitly set to one of the TZ-enabled ones like
cortex-a15. (The default "any" CPU doesn't have TZ enabled and so is
not affected.)
Use access_secure_reg() to determine whether we should be using
the secure or the nonsecure copy of TPIDRURO when emulating these
syscalls.

target-arm: Ignore low bit of PC in M-profile exception return
For the ARM M-profile cores, exception return pops various registers
including the PC from the stack. The architecture defines that if the
lowest bit in the new PC value is set (ie the PC is not halfword
aligned) then behaviour is UNPREDICTABLE. In practice hardware
implementations seem to simply ignore the low bit, and some buggy
RTOSes incorrectly rely on this. QEMU's behaviour was architecturally
permitted, but bringing QEMU into line with the hardware behaviour
allows more guest code to run. We log the situation as a guest error.

The A32 encoding of LDM distinguishes LDM (user) from LDM (exception
return) based on whether r15 is in the register list. However for
STM (user) there is no equivalent distinction. We were incorrectly
treating "r15 in list" as indicating exception return for both LDM
and STM, with the result that an STM (user) involving r15 went into
an infinite loop. Fix this; note that the value stored for r15
in this case is the current PC regardless of our current mode.

This patch makes the following changes to the determination of
whether an address is executable, when translating addresses
using LPAE.
1. No longer assumes that PL0 can't execute when it can't read.
It can in AArch64, a difference from AArch32.
2. Use va_size == 64 to determine we're in AArch64, rather than
arm_feature(env, ARM_FEATURE_V8), which is insufficient.
3. Add additional XN determinants
- NS && is_secure && (SCR & SCR_SIF)
- WXN && (prot & PAGE_WRITE)
- AArch64: (prot_PL0 & PAGE_WRITE)
- AArch32: UWXN && (prot_PL0 & PAGE_WRITE)
- XN determination should also work in secure mode (untested)
- XN may even work in EL2 (currently impossible to test)
4. Cleans up the bloated PAGE_EXEC condition - by removing it.
The helper get_S1prot is introduced. It may even work in EL2,
when support for that comes, but, as the function name implies,
it only works for stage 1 translations.

Check for the aes_key_wrap and dea_key_wrap machine options and set the
appropriate KVM device attribute(s) to tell the kernel to enable or disable
the AES/DEA protected key functions for the guest domain.
This patch introduces two new machine options for indicating the state of
AES/DEA key wrapping functions. This controls whether the guest will
have access to the AES/DEA crypto functions.
aes_key_wrap="on | off" is changed to aes-key-wrap="on | off"
dea_key_wrap="on | off" is changed to dea-key-wrap="on | off"

complains to stderr and succeeds.
Except it can't actually fail, because the "s390-flic-qemu" is a dummy
without a realize method, and "s390-flic-kvm"'s realize can't fail,
even when the kernel device is really unavailable. Odd.

queue: fix QSLIST_INSERT_HEAD_ATOMIC race
There is a not-so-subtle race in QSLIST_INSERT_HEAD_ATOMIC.
Because atomic_cmpxchg returns the old value instead of a success flag,
QSLIST_INSERT_HEAD_ATOMIC was checking for success by comparing against
the second argument to atomic_cmpxchg. Unfortunately, this only works
if the second argument is a local or thread-local variable.
If it is in memory, it can be subject to common subexpression elimination
(and then everything's fine) or reloaded after the atomic_cmpxchg,
depending on the compiler's whims. If the latter happens, the race can
happen. A thread can sneak in, doing something on elm->field.sle_next
after the atomic_cmpxchg and before the comparison. This causes a wrong
failure, and then two threads are using "elm" at the same time. In the
case discovered by Christian, the sequence was likely something like this:
thread 1 | thread 2
QSLIST_INSERT_HEAD_ATOMIC |
atomic_cmpxchg succeeds |
elm added to list |
| steal release_pool
| QSLIST_REMOVE_HEAD
| elm removed from list
| ...
| QSLIST_INSERT_HEAD_ATOMIC
| (overwrites sle_next)
spurious failure |
atomic_cmpxchg succeeds |
elm added to list again |
|
steal release_pool |
QSLIST_REMOVE_HEAD |
elm removed again |
The last three steps could be done by a third thread as well.
A reproducer that failed in a matter of seconds is as follows:
- the guest has 32 VCPUs on a 28 core host (hyperthreading was enabled),
memory was 16G just to err on the safe side (the host has 64G, but hey
at least you need no s390)
- the guest has 24 null-aio virtio-blk devices using dataplane
(-object iothread,id=ioN -drive if=none,id=blkN,driver=null-aio,size=500G
-device virtio-blk-pci,iothread=ioN,drive=blkN)
- the guest also has a single network interface. It's only doing loopback

Omit one unnecessary memory allocation for components
of the path and create the resulting path directly given
lengths of the components.
Do not use basename(3) because there are 2 versions of
this function which differs when argument ends with
slash character, use strrchr() instead so we have
consistent result. This also makes sure the function
will do the right thing in corner cases (eg, empty
pathname is given), when basename(3) return entirely
another string.
