curl: Make sslverify=off disable host as well as peer verification.
The sslverify setting is supposed to turn off all TLS certificate
checks in libcurl. However because of the way we use it, it only
turns off peer certificate authenticity checks
(CURLOPT_SSL_VERIFYPEER). This patch makes it also turn off the check
that the server name in the certificate is the same as the server
you're connecting to (CURLOPT_SSL_VERIFYHOST).
We can use Google's server at 8.8.8.8 which happens to have a bad TLS
certificate to demonstrate this:
$ ./qemu-img create -q -f qcow2 -b 'json: { "file.sslverify": "off", "file.driver": "https", "file.url": "https://8.8.8.8/foo" }' /var/tmp/file.qcow2
qemu-img: /var/tmp/file.qcow2: CURL: Error opening file: SSL: no alternative certificate subject name matches target host name '8.8.8.8'
Could not open backing image to determine size.
With this patch applied, qemu-img connects to the server regardless of
the bad certificate:
$ ./qemu-img create -q -f qcow2 -b 'json: { "file.sslverify": "off", "file.driver": "https", "file.url": "https://8.8.8.8/foo" }' /var/tmp/file.qcow2
qemu-img: /var/tmp/file.qcow2: CURL: Error opening file: The requested URL returned error: 404 Not Found
(The 404 error is expected because 8.8.8.8 is not actually serving a
file called "/foo".)
Of course the default (without sslverify=off) remains to always check
the certificate:
$ ./qemu-img create -q -f qcow2 -b 'json: { "file.driver": "https", "file.url": "https://8.8.8.8/foo" }' /var/tmp/file.qcow2
qemu-img: /var/tmp/file.qcow2: CURL: Error opening file: SSL: no alternative certificate subject name matches target host name '8.8.8.8'
Could not open backing image to determine size.

block/rbd: Attempt to parse legacy filenames
When we converted rbd to get rid of the older key/value-centric
encoding format, we broke compatibility with image files with backing
file strings encoded in the old format.
This leaves a bit of an ugly conundrum, and a hacky solution.
If the initial attempt to parse the "proper" options fails, it assumes
that we may have an older key/value encoded filename. Fall back to
attempting to parse the filename, and extract the required options from
it. If that fails, pass along the original error message.
We do not support mixed modern usage alongside legacy keyvalue pair
usage.
A deprecation warning has been added, although care should be taken
when actually deprecating since the impact is not limited to
commandline or qapi usage, but also opening existing images.

40p: use OR gate to wire up raven PCI interrupts
According to the PReP specification section 6.1.6 "System Interrupt
Assignments", all PCI interrupts are routed via IRQ 15.
Instead of mapping each PCI IRQ separately, we introduce an OR gate within the
raven PCI host bridge and then wire the single output of the OR gate to the
interrupt controller.
Note that whilst the (now deprecated) PReP machine still exists we still need
to preserve the old IRQ routing. This is done by adding a new "is-legacy-prep"
property to the raven PCI host bridge which is set to true for the PReP
machine.

json: Nicer recovery from lexical errors
When the lexer chokes on an input character, it consumes the
character, emits a JSON error token, and enters its start state. This
can lead to suboptimal error recovery. For instance, input
0123 ,
produces the tokens
JSON_ERROR 01
JSON_INTEGER 23
JSON_COMMA ,
Make the lexer skip characters after a lexical error until a
structural character ('[', ']', '{', '}', ':', ','), an ASCII control
character, or '\xFE', or '\xFF'.
Note that we must not skip ASCII control characters, '\xFE', '\xFF',
because those are documented to force the JSON parser into known-good
state, by docs/interop/qmp-spec.txt.
The lexer now produces
JSON_ERROR 01
JSON_COMMA ,
Update qmp-test for the nicer error recovery: QMP now reports just one
error for input %p instead of two. Also drop the newline after %p; it
was needed to tease out the second error.

json: Make lexer's "character consumed" logic less confusing
The lexer uses macro TERMINAL_NEEDED_LOOKAHEAD() to decide whether a
state transition consumes the input character. It returns true when
the state transition is defined with the TERMINAL() macro. To detect
that, it checks whether input '\0' would have resulted in the same
state transition, and the new state is not IN_ERROR.
Why does that even work? For all states, the new state on input '\0'
is either IN_ERROR or defined with TERMINAL(). If the state
transition equals the one we'd get for input '\0', it goes to IN_ERROR
or to the argument of TERMINAL(). We never use TERMINAL(IN_ERROR),
because it makes no sense. Thus, if it doesn't go to IN_ERROR, it
must be defined with TERMINAL().
Since this isn't quite confusing enough, we negate the result to get
@char_consumed, and ignore it when @flush is true.
Instead of deriving the lookahead bit from the state transition, make
it explicit. This is easier to understand, and a bit more flexible,
too.

json: Clean up how lexer consumes "end of input"
When the lexer isn't in its start state at the end of input, it's
working on a token. To flush it out, it needs to transit to its start
state on "end of input" lookahead.
There are two ways to the start state, depending on the current state:
* If the lexer is in a TERMINAL(JSON_FOO) state, it can emit a
JSON_FOO token.
* Else, it can go to IN_ERROR state, and emit a JSON_ERROR token.
There are complications, however:
* The transition to IN_ERROR state consumes the input character and
adds it to the JSON_ERROR token. The latter is inappropriate for
the "end of input" character, so we suppress that. See also recent
commit
a2ec6be72b8 "json: Fix lexer to include the bad character in
JSON_ERROR token".
* The transition to a TERMINAL(JSON_FOO) state doesn't consume the
input character. In that case, the lexer normally loops until it is
consumed. We have to suppress that for the "end of input" input
character. If we didn't, the lexer would consume it by entering
IN_ERROR state, emitting a bogus JSON_ERROR token. We fixed that in
commit
bd3924a33a6.
However, simply breaking the loop this way assumes that the lexer
needs exactly one state transition to reach its start state. That
assumption is correct now, but it's unclean, and I'll soon break it.
Clean up: instead of breaking the loop after one iteration, break it
after it reached the start state.

pc: acpi: revert back to 1 SRAT entry for hotpluggable area
Commit
10efd7e108 "pc: acpi: fix memory hotplug regression by reducing stub SRAT entry size"
attemped to fix hotplug regression introduced by
848a1cc1e "hw/acpi-build: build SRAT memory affinity structures for DIMM devices"
fixed issue for Windows/3.0+ linux kernels, however it regressed 2.6 based
kernels (RHEL6) to the point where guest might crash at boot.
Reason is that 2.6 kernel discards SRAT table due too small last entry
which down the road leads to crashes. Hack I've tried in
10efd7e108 is also
not ACPI spec compliant according to which whole possible RAM should be
described in SRAT. Revert
10efd7e108 to fix regression for 2.6 based kernels.
With
10efd7e108 reverted, I've also tried splitting SRAT table statically
in different ways %/node and %/slot but Windows still fails to online
2nd pc-dimm hot-plugged into node 0 (as described in
10efd7e108) and
sometimes even coldplugged pc-dimms where affected with static SRAT
partitioning.
The only known so far way where Windows stays happy is when we have 1
SRAT entry in the last node covering all hotplug area.
Revert
848a1cc1e until we come up with a way to avoid regression
on Windows with hotplug area split in several entries.
Tested this with 2.6/3.0 based kernels (RHEL6/7) and WS20[08/12/12R2/16]).

Fix a deadlock case in the CPU hotplug flow
We need to set cs->halted to 1 before calling ppc_set_compat. The reason
is that ppc_set_compat kicks up the new thread created to manage the
hotplugged KVM virtual CPU and the code drives directly to KVM_RUN
ioctl. When cs->halted is 1, the code:
int kvm_cpu_exec(CPUState *cpu)
...
if (kvm_arch_process_async_events(cpu)) {
atomic_set(&cpu->exit_request, 0);
return EXCP_HLT;
}
...
returns before it reaches KVM_RUN, giving time to the main thread to
finish its job. Otherwise we can fall in a deadlock because the KVM
thread will issue the KVM_RUN ioctl while the main thread is setting up
KVM registers. Depending on how these jobs are scheduled we'll end up
freezing QEMU.
The following output shows kvm_vcpu_ioctl sleeping because it cannot get
the mutex and never will.
PS: kvm_vcpu_ioctl was triggered kvm_set_one_reg - compat_pvr.

jobs: utilize job_exit shim
Utilize the job_exit shim by not calling job_defer_to_main_loop, and
where applicable, converting the deferred callback into the job_exit
callback.
This converts backup, stream, create, and the unit tests all at once.
Most of these jobs do not see any changes to the order in which they
clean up their resources, except the test-blockjob-txn test, which
now puts down its bs before job_completed is called.
This is safe for the same reason the reordering in the mirror job is
safe, because job_completed no longer runs under two locks, making
the unref safe even if it causes a flush.

Kevin highlights that we did not take any permissions for that backend

jobs: add exit shim
All jobs do the same thing when they leave their running loop:
- Store the return code in a structure
- wait to receive this structure in the main thread
- signal job completion via job_completed
Few jobs do anything beyond exactly this. Consolidate this exit
logic for a net reduction in SLOC.
More seriously, when we utilize job_defer_to_main_loop_bh to call
a function that calls job_completed, job_finalize_single will run
in a context where it has recursively taken the aio_context lock,
which can cause hangs if it puts down a reference that causes a flush.
You can observe this in practice by looking at mirror_exit's careful
placement of job_completed and bdrv_unref calls.
If we centralize job exiting, we can signal job completion from outside
of the aio_context, which should allow for job cleanup code to run with
only one lock, which makes cleanup callbacks less tricky to write.

Presently we codify the entry point for a job as the "start" callback,
but a more apt name would be "run" to clarify the idea that when this
function returns we consider the job to have "finished," except for
any cleanup which occurs in separate callbacks later.
As part of this clarification, change the signature to include an error

code while captured, will be overwritten by actions in the job_completed
