8aa1331c09 vmdk: check granularity field in opening
Granularity is used to calculate the cluster size and allocate r/w
buffer. Check the value from image before using it, so we don't abort()

8afaefb891 block: Disable driver-specific options for 1.6
We don't want to commit to the API yet before everything is worked out.
Like already for 1.5, disable it again for the 1.6 release. This commit
is meant to be reverted after the 1.6 release.

The disabling of the driver-specific options is achieved by applying the
old checks while parsing the command line.

c7a3f25200 qapi.py: Restructure lexer and parser
The parser has a rather unorthodox structure:

    Until EOF:

        Read a section:

            Generator function get_expr() yields one section after the
            other, as a string.  An unindented, non-empty line that
            isn't a comment starts a new section.

        Lexing:

            Split section into a list of tokens (strings), with help
            of generator function tokenize().

        Parsing:

            Parse the first expression from the list of tokens, with
            parse(), throw away any remaining tokens.

            In parse_schema(): record value of an enum, union or
            struct key (if any) in the appropriate global table,
            append expression to the list of expressions.

    Return list of expressions.

Known issues:

(1) Indentation is significant, unlike in real JSON.

(2) Neither lexer nor parser have any idea of source positions.  Error
    reporting is hard, let's go shopping.

(3) The one error we bother to detect, we "report" via raise.

(4) The lexer silently ignores invalid characters.

(5) If everything in a section gets ignored, the parser crashes.

(6) The lexer treats a string containing a structural character exactly
    like the structural character.

(7) Tokens trailing the first expression in a section are silently
    ignored.

(8) The parser accepts any token in place of a colon.

(9) The parser treats comma as optional.

(10) parse() crashes on unexpected EOF.

(11) parse_schema() crashes when a section's expression isn't a JSON
    object.

Replace this piece of original art by a thoroughly unoriginal design.
Takes care of (1), (2), (5), (6) and (7), and lays the groundwork for
addressing the others.  Generated source files remain unchanged.

Multiplication of two fractional word elements is not correct when sign
extension/promotion is needed. This change fixes it by adding correct

In addition, the tests (dpaq_sa_l_w.c and dpsq_sa_l_w.c) have been extended

98289620e0 block: Don't parse protocol from file.filename
One of the major reasons for doing something new for -blockdev and
blockdev-add was that the old block layer code parses filenames instead
of just taking them literally. So we should really leave it untouched
when it's passing using the new interfaces (like -drive
file.filename=...).

This allows opening relative file names that contain a colon.

b53169eae0 blockdev: add sync mode to drive-backup QMP command
The drive-backup command is similar to the drive-mirror command, except
no guest data written after the command executes gets copied.  Add a
sync mode argument which determines whether the entire disk is copied,
just allocated clusters, or only clusters being written to by the guest.

Currently only sync mode 'full' is supported - it copies the entire disk.
For read-only point-in-time snapshots we may only need sync mode 'none'
since the target can be a qcow2 file using the guest's disk as its
backing file (no need to copy the entire disk).  Finally, sync mode
'top' is useful if we wish to preserve the backing chain.

Note that this patch just adds the sync mode argument to drive-backup.
It does not implement sync modes 'top' or 'none'.  This patch is
necessary so we can add a drive-backup HMP command that behaves like the
existing drive-mirror HMP command and takes a sync mode.

22bfa16ed3 ide-test: fix failure for test_flush
bd07684aac added a test to ensure BSY
flag is set when a flush request is in flight. It does this by setting
a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE.
It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset.

The actual unsetting of BSY does not occur until ide_flush_cb gets
called in a bh, however, so in some cases this check will race with
the actual completion.

Fix this by polling the ide status register until BSY flag gets unset
before we do our final sanity checks. According to
f68ec8379e this is in line with how a guest
would determine whether or not the device is still busy.

a678e26cbe qapi: pad GenericList value fields to 64 bits
With the introduction of native list types, we now have types such as
int64List where the 'value' field is not a pointer, but the actual
64-bit value.

On 32-bit architectures, this can lead to situations where 'next' field
offset in GenericList does not correspond to the 'next' field in the
types that we cast to GenericList when using the visit_next_list()
interface, causing issues when we attempt to traverse linked list
structures of these types.

To fix this, pad the 'value' field of GenericList and other
schema-defined/native *List types out to 64-bits.

This is less memory-efficient for 32-bit architectures, but allows us to
continue to rely on list-handling interfaces that target GenericList to
simply visitor implementations.

In the future we can improve efficiency by defaulting to using native C
array backends to handle list of non-pointer types, which would be more
memory efficient in itself and allow us to roll back this change.

Set MALLOC_PERTURB_ for gtester and qemu-iotests.  Note we pick a random
value from 1 to 255 to expose more bugs.  If you need to reproduce a
crash use 'show environment' in gdb to extract the MALLOC_PERTURB_

Cover new image creation options for vmdk, so we can use '-o
zeroed_grain=XXX' and '-o subformat=XXX' to run the tests successfully.

libqtest.c can segfault when calling fclose() if the pidfile wasn't
opened successfully. This patch fixes the issue.

1a63e059de libqos: Convert fw_cfg values to host endianness
The fw_cfg ABI is Little Endian, so byte-swap the generically read
byte array to host endianness.

This unbreaks the fw_cfg tests on ppc.

8ec7d390b0 block: Disable driver-specific options for 1.5
We don't want to commit to the API yet before everything is worked out.
Disable it for the 1.5 release. This commit is meant to be reverted
after the 1.5 release.

The disabling of the driver-specific options is achieved by applying the
old checks while parsing the command line.

7da94ca741 qemu-iotests: add 053 unaligned compressed image size test
Test that qemu-img convert -c works when input image length is not a
multiple of the cluster size.

Previously an error message would be produced:

  qemu-img: error while compressing sector 0: Input/output error

Now that qcow2 and qcow handle this case the test passes successfully.

bdda92324d qemu-iotests: Fix _filter_qemu
$QEMU_PROG happens to be 'qemu' in my setup, so this sed command
replaces a bit too much. Restrict it to the start of the line and to
when it's followed by a colon, i.e. the form used by error messages.

a875711af9 i440fx-test: add test for PAM functionality
This tests PAM settings for the i440fx.  This test does a lot of
byte MMIO which is fairly slow with qtest today.  But the test
does complete in under 2 seconds.

We don't fully emulate PAM largely because of limitations with
KVM so we #if 0 that part of the test case.

9bda413c96 i440fx-test: add test to compare default register values
This test compares all of the default register values against the
spec.  It turns out we deviate in quite a few places.  These
places are really only visible to the BIOS though which is why
this hasn't created any problems.

The deviation actually happens in the core PCI layer so I suspect
it's not a simple fix if we really care to fix it.  For now, just
disable the affected checks.
