Daniel P. Berrange e4a3507e86 crypto: move 'opaque' parameter to (nearly) the end of parameter list
Previous commit moved 'opaque' to be the 2nd parameter in the list:

  commit 375092332e
  Author: Fam Zheng <famz@redhat.com>
  Date:   Fri Apr 21 20:27:02 2017 +0800

    crypto: Make errp the last parameter of functions

    Move opaque to 2nd instead of the 2nd to last, so that compilers help
    check with the conversion.

this puts it back to the 2nd to last position.

Markus Armbruster bd269ebc82 sockets: Limit SocketAddressLegacy to external interfaces
SocketAddressLegacy is a simple union, and simple unions are awkward:
they have their variant members wrapped in a "data" object on the
wire, and require additional indirections in C.  SocketAddress is the
equivalent flat union.  Convert all users of SocketAddressLegacy to
SocketAddress, except for existing external interfaces.

See also commit fce5d53..9445673 and 85a82e8..c5f1ae3.

Markus Armbruster dfd100f242 sockets: Rename SocketAddress to SocketAddressLegacy
The next commit will rename SocketAddressFlat to SocketAddress, and
the commit after that will replace most uses of SocketAddressLegacy by
SocketAddress, replacing most of this commit's renames right back.

Note that checkpatch emits a few "line over 80 characters" warnings.
The long lines are all temporary; the SocketAddressLegacy replacement
will shorten them again.

Eric Blake 5229564b83 test-qga: Actually test 0xff sync bytes
Commit 62c39b3 introduced test-qga, and at face value, appears
to be testing the 'guest-sync' behavior that is recommended for
guests in sending 0xff to QGA to force the parser to reset.  But
this aspect of the test has never actually done anything: the
qmp_fd() call chain converts its string argument into QObject,
then converts that QObject back to the actual string that is
sent over the wire - and the conversion process silently drops
the 0xff byte from the string sent to QGA, thus never resetting
the QGA parser.

An upcoming patch will get rid of the wasteful round trip
through QObject, at which point the string in test-qga will be
directly sent over the wire.

But fixing qmp_fd() to actually send 0xff over the wire is not
all we have to do - the actual QMP parser loudly complains that
0xff is not valid JSON, and sends an error message _prior_ to
actually parsing the 'guest-sync' or 'guest-sync-delimited'
command.  With 'guest-sync', we cannot easily tell if this error
message is a result of our command - which is WHY we invented
the 'guest-sync-delimited' command.  So for the testsuite, fix
things to only check 0xff behavior on 'guest-sync-delimited',
and to loop until we've consumed all garbage prior to the
requested delimiter, which is compatible with the documented actions
that a real QGA client is supposed to do.

Ideally, we'd fix the QGA JSON parser to silently ignore 0xff
rather than sending an error message back, at which point we
could enhance this test for 'guest-sync' as well as for
'guest-sync-delimited'.  But for the sake of this patch, our
testing of 'guest-sync' is no worse than it was pre-patch,
because we have never been sending 0xff over the wire in the
first place.

Phil Dennis-Jordan 77af8a2b95 hw/i386: Use Rev3 FADT (ACPI 2.0) instead of Rev1 to improve guest OS support.
This updates the FADT generated for x86/64 machine types from Revision 1 to 3. (Based on ACPI standard 2.0 instead of 1.0) The intention is to expose the reset register information to guest operating systems which require it, specifically OS X/macOS. Revision 1 FADTs do not contain the fields relating to the reset register.

The new layout and contents remains backwards-compatible with operating systems which only support ACPI 1.0, as the existing fields are not modified by this change, as the 64-bit and 32-bit variants are allowed to co-exist according to the ACPI 2.0 standard. No regressions became apparent in tests with a range of Windows (XP-10) and Linux versions.

The BIOS tables test suite's FADT checksum test has also been updated to reflect the new FADT layout and content.

Eric Blake 048c5fd1bf qcow2: Allow discard of final unaligned cluster
As mentioned in commit 0c1bd46, we ignored requests to
discard the trailing cluster of an unaligned image.  While
discard is an advisory operation from the guest standpoint,
(and we are therefore free to ignore any request), our
qcow2 implementation exploits the fact that a discarded
cluster reads back as 0.  As long as we discard on cluster
boundaries, we are fine; but that means we could observe
non-zero data leaked at the tail of an unaligned image.

Enhance iotest 66 to cover this case, and fix the implementation
to honor a discard request on the final partial cluster.

It does not make much sense to use a backing image for the target when
you concatenate multiple images (because then there is no correspondence
between the source images' backing files and the target's); but it was
still possible to give one by using -o backing_file=X instead of -B X.

Fix this by moving the check.

(Also, change the error message because -B is not the only way to
 specify the backing file, evidently.)

Fam Zheng 24dfdfd0ff iotests: 109: Filter out "len" of failed jobs
Mirror calculates job len from current I/O progress:

    s->common.len = s->common.offset +
                    (cnt + s->sectors_in_flight) * BDRV_SECTOR_SIZE;

The final "len" of a failed mirror job in iotests 109 depends on the
subtle timing of the completion of read and write issued in the first
mirror iteration.  The second iteration may or may not have run when the
I/O error happens, resulting in non-deterministic output of the
BLOCK_JOB_COMPLETED event text.

Similar to what was done in a752e4786, filter out the field to make the
test robust.

Stefan Hajnoczi d72915c60b throttle: make throttle_config(throttle_get_config()) symmetric
Throttling has a weird property that throttle_get_config() does not
always return the same throttling settings that were given with
throttle_config().  In other words, the set and get functions aren't
symmetric.

If .max is 0 then the throttling code assigns a default value of .avg /
10 in throttle_config().  This is an implementation detail of the
throttling algorithm.  When throttle_get_config() is called the .max
value returned should still be 0.

Users are exposed to this quirk via "info block" or "query-block"
monitor commands.  This has caused confusion because it looks like a bug
when an unexpected value is reported.

This patch hides the .max value adjustment in throttle_get_config() and
updates test-throttle.c appropriately.

Fam Zheng e92f0e1910 block: Use bdrv_coroutine_enter to start I/O coroutines
BDRV_POLL_WHILE waits for the started I/O by releasing bs's ctx then polling
the main context, which relies on the yielded coroutine continuing on bs->ctx
before notifying qemu_aio_context with bdrv_wakeup().

Thus, using qemu_coroutine_enter to start I/O is wrong because if the coroutine
is entered from main loop, co->ctx will be qemu_aio_context, as a result of the
"release, poll, acquire" loop of BDRV_POLL_WHILE, race conditions happen when
both main thread and the iothread access the same BDS:

  main loop                                iothread

              /* (A) bdrv_co_flush(bs)           /* (B) I/O on bs */

        aio_context_acquire(bs->ctx)

Note that in above case, bdrv_drained_begin() doesn't do the "release,
poll, acquire" in BDRV_POLL_WHILE, because bs->in_flight == 0.

Fix this by using bdrv_coroutine_enter and enter coroutine in the right
context.

iotests 109 output is updated because the coroutine reenter flow during
mirror job complete is different (now through co_queue_wakeup, instead
of the unconditional qemu_coroutine_switch before), making the end job
len different.

extended the 097 test case so that it did two passes, once
with an internal snapshot, once without.

qcow (v1) does not support internal snapshots, so this change
broke test 097 when run against qcow.

This splits 097 in two, creating a new 176 that tests the
internal snapshot codepath, effectively putting 097 back
to its content before the above commit.

Markus Armbruster 9445673ea6 nbd: Tidy up blockdev-add interface
SocketAddress is a simple union, and simple unions are awkward: they
have their variant members wrapped in a "data" object on the wire, and
require additional indirections in C.  I intend to limit its use to
existing external interfaces, and convert all internal interfaces to
SocketAddressFlat.

BlockdevOptionsNbd is an external interface using SocketAddress.  We
already use SocketAddressFlat elsewhere in blockdev-add.  Replace it
by SocketAddressFlat while we can (it's new in 2.9) for simplicity and
consistency.  For example,

    { "execute": "blockdev-add",
      "arguments": { "node-name": "foo", "driver": "nbd",
                     "server": { "type": "inet",
		                 "data": { "host": "localhost",
				           "port": "12345" } } } }

becomes

    { "execute": "blockdev-add",
      "arguments": { "node-name": "foo", "driver": "nbd",
                     "server": { "type": "inet",
		                 "host": "localhost", "port": "12345" } } }

Since the internal interfaces still take SocketAddress, this requires
conversion function socket_address_crumple().  It'll go away when I
update the interfaces.

Unfortunately, SocketAddress is also visible in -drive since 2.8:

    -drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345

Nobody should be using it, as it's fairly new and has never been
documented, so adding still more compatibility gunk to keep it working
isn't worth the trouble.  You now have to use

    -drive if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345

[mreitz: Change iotest 147 accordingly]

Because of this interface change, iotest 147 has to be adapted.
Unfortunately, we cannot just flatten all of the addresses because
nbd-server-start still takes a plain SocketAddress. Therefore, we need
both and this is most easily achieved by writing the SocketAddress into
the code and flattening it where necessary.

Visiting a list when input is the empty string should result in an

Markus Armbruster 1d8bda128d qapi: The #optional tag is redundant, drop
We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.

Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional.  This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out.  We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.

Thus, you can't actually rely on #optional to see whether something is
optional.  Yet we still make people add it manually.  That's just
busy-work.

Drop the code to check, fix up and strip out #optional, along with all
instances of #optional.  To keep it out, add code to reject it, to be
dropped again once the dust settles.

No change to generated documentation.

Markus Armbruster bc52d03ff5 qapi: Make doc comments optional where we don't need them
Since we added the documentation generator in commit 3313b61, doc
comments are mandatory.  That's a very good idea for a schema that
needs to be documented, but has proven to be annoying for testing.

Make doc comments optional again, but add a new directive

    { 'pragma': { 'doc-required': true } }

to let a QAPI schema require them.

Add test cases for the new pragma directive.  While there, plug a
minor hole in includ directive test coverage.

Require documentation in the schemas we actually want documented:
qapi-schema.json and qga/qapi-schema.json.

We could probably make qapi2texi.py cope with incomplete
documentation, but for now, simply make it refuse to run unless the
schema has 'doc-required': true.

The only functional difference between the GENERATED_HEADERS
and GENERATED_SOURCES variables is that 'Makefile' has a
dependancy on GENERATED_HEADERS, causing generated header files
to be created immediatey at the start of the build process.
There is no reason why this early creation should be restricted
to the .h files, and not include .c files too. Merge both of
the variables into a single GENERATED_FILES variable to make
it clear it is for any type of generated file.

Eric Blake e32ccbc6e9 block: Drop unmaintained 'archipelago' driver
The driver has failed to build since commit da34e65, in qemu 2.6,
due to a missing include of qapi/error.h for error_setg().
Since no one has complained in three releases, it is easier to
remove the dead code than to keep it around, especially since it
is not being built by default and therefore prone to bitrot.

  is equivalent to JSON [ "null", "eins", "zwei" ]

* a.b.c=1,a.b.0=2
  is inconsistent: a.b.c clashes with a.b.0

* list.0=null,list.2=eins,list.2=zwei
  has a hole: list.1 is missing

Similar design flaw as for objects: there is no way to denote an empty
list.  While interpreting "key absent" as empty list seems natural
(removing a list member from the input string works when there are
multiple ones, so why not when there's just one), it doesn't work:
"key absent" already means "optional list absent", which isn't the
same as "empty list present".

Update the keyval object visitor to use this a.0 syntax in error
messages rather than the usual a[0].

Markus Armbruster f740048323 keyval: Restrict key components to valid QAPI names
Until now, key components are separated by '.'.  This leaves little
room for evolving the syntax, and is incompatible with the __RFQDN_
prefix convention for downstream extensions.

Since key components will be commonly used as QAPI member names by the
QObject input visitor, we can just as well borrow the QAPI naming
rules here: letters, digits, hyphen and period starting with a letter,
with an optional __RFQDN_ prefix for downstream extensions.

Markus Armbruster 02146d27c3 test-visitor-serialization: Pass &error_abort to qobject_from_json()
qmp_deserialize() calls qobject_from_json() ignoring errors.  It
passes the result to qobject_input_visitor_new(), which asserts it's
not null.  Therefore, we can just as well pass &error_abort to
qobject_from_json().
