Richard W.M. Jones 637fa44ab8 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.

Further information about the two settings is available here:

https://curl.haxx.se/libcurl/c/CURLOPT_SSL_VERIFYPEER.html
https://curl.haxx.se/libcurl/c/CURLOPT_SSL_VERIFYHOST.html

Jeff Cody 66e6a735e9 block/rbd: add iotest for rbd legacy keyvalue filename parsing
This is a small test that will check for the ability to parse
both legacy and modern options for rbd.

The way the test is set up is for failure to occur, but without
having to wait to timeout on a non-existent rbd server.  The error
messages in the success path show that the arguments were parsed.

The failure behavior prior to the patch series that has this test, is
qemu-img complaining about mandatory options (e.g. 'pool') not being
provided.

Jeff Cody 084d1d13bd 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.

Mark Cave-Ayland 0358687b16 40p: add fixed IRQ routing for LSI SCSI device
Whilst the PReP specification describes how all PCI IRQs are routed via IRQ
15 on the interrupt controller, the real 40p machine has a routing quirk in
that the LSI SCSI device is routed directly to IRQ 13.

Enable the external IRQ for the LSI SCSI device by wiring up the IRQ with
qdev to the relevant interrupt controller gpio.

Mark Cave-Ayland 877eb21d56 scsi: move lsi53c8xx_create() callers to lsi53c8xx_handle_legacy_cmdline()
As part of commits a64aa5785d "hw: Deprecate -drive if=scsi with non-onboard
HBAs" and b891538e81 "hw/ppc/prep: Fix implicit creation of "-drive if=scsi"
devices" the lsi53c895a_create() and lsi53c810_create() functions were added
to wrap pci_create_simple() and scsi_bus_legacy_handle_cmdline().

Unfortunately this prevents us from changing qdev properties on the device
and/or changing the PCI configuration. By switching over to using the new
lsi53c8xx_handle_legacy_cmdline() function then the caller can now configure
and realize the LSI SCSI device exactly as required.

Cédric Le Goater ae83740237 spapr: increase the size of the IRQ number space
The new layout using static IRQ number does not leave much space to
the dynamic MSI range, only 0x100 IRQ numbers. Increase the total
number of IRQS for newer machines and introduce a legacy XICS backend
for pre-3.1 machines to maintain compatibility.

For the old backend, provide a 'nr_msis' value covering the full IRQ
number space as it does not use the bitmap allocator to allocate MSI
interrupt numbers.

Cédric Le Goater e39de895f6 spapr: introduce a spapr_irq class 'nr_msis' attribute
The number of MSI interrupts a sPAPR machine can allocate is in direct
relation with the number of interrupts of the sPAPRIrq backend. Define
statically this value at the sPAPRIrq class level and use it for the
"ibm,pe-total-#msi" property of the sPAPR PHB.

According to the PAPR specs, "ibm,pe-total-#msi" defines the maximum
number of MSIs that are available to the PE. We choose to advertise
the maximum number of MSIs that are available to the machine for
simplicity of the model and to avoid segmenting the MSI interrupt pool
which can be easily shared. If the pool limit is reached, it can be
extended dynamically.

Finally, remove XICS_IRQS_SPAPR which is now unused.

Mark Cave-Ayland f40b83a4e3 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.

Markus Armbruster 1e960b4602 json: Eliminate lexer state IN_WHITESPACE, pseudo-token JSON_SKIP
The lexer ignores whitespace like this:

         on whitespace      on non-ws   spontaneously
    IN_START --> IN_WHITESPACE --> JSON_SKIP --> IN_START
                    ^    |
                     \__/  on whitespace

This accumulates a whitespace token in state IN_WHITESPACE, only to
throw it away on the transition via JSON_SKIP to the start state.
Wasteful.  Go from IN_START to IN_START on whitespace directly,
dropping the whitespace character.

Markus Armbruster 0f07a5d5f1 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.

Markus Armbruster c0ee3afa7f 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.

Markus Armbruster 852dfa76b8 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 a2ec6be72b "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 bd3924a33a.

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.

Markus Armbruster 2a96042a8d json: Fix lexer for lookahead character beyond '\x7F'
The lexer fails to end a valid token when the lookahead character is
beyond '\x7F'.  For instance, input

    true\xC2\xA2

produces the tokens

    JSON_ERROR     true\xC2
    JSON_ERROR     \xA2

This should be

    JSON_KEYWORD   true
    JSON_ERROR     \xC2
    JSON_ERROR     \xA2

instead.

The culprit is

    #define TERMINAL(state) [0 ... 0x7F] = (state)

It leaves [0x80..0xFF] zero, i.e. IN_ERROR.  Has always been broken.
Fix it to initialize the complete array.

Max Filippov 7a54cfbcee target/xtensa: fix s32c1i TCGMemOp flags
s32c1i must load and store value with target endianness, not host.
This results in an infinite loop in atomic cmpxchg sequences when target
endianness doesn't match host endianness.
