96c044afdf qemu-option: Replace pointless use of g_malloc0() by g_malloc()
get_opt_value() takes a write-only buffer, so zeroing it is pointless.
We don't do it elsewhere, either.

All libcacard actually needs are the NSS libs. Linking against the entire
world is a regression caused by

  commit 9d171bd937
  Author: Michael Tokarev <mjt@tls.msk.ru>
  Date:   Thu May 8 16:48:27 2014 +0400

    libcacard: remove libcacard-specific CFLAGS and LIBS from global vars

Which removed the setting of the LIBS variable in libcacard/Makefile.

Adding it back as an empty assignment brings the linked libs back to a more
reasonable set

7eff518b6c linux-user/syscall.c: lock_iovec: unlock vec[i] in failure processing code block
When failure occurs during locking of vec[i], we also need to unlock all
already locked vec[i] in failure processing code block before return.

Code in unlock_user() checks vec[i].iov_base for NULL, so there's no
need not check it .

If error is EFAULT when "i == 0", vec[i].iov_base is NULL, we can just
skip it, so can still use "while (--i >= 0)" loop condition.

46ede58bb4 vl: Fix bogus error message for implied mon ID clashing
monitor_parse() desugars --monitor, --qmp and -qmp-pretty to --mon.
The ID it picks can clash with a user-specified ID.  When it happens,
the error message is misleading.

Reproducer:

    $ qemu --mon id=compat_monitor0 --monitor stdio

Message before the patch:

    duplicate chardev: compat_monitor0

There's no "duplicate chardev" here.  The problem is a duplicate
monitor ID.  Moreover, the message provides no clue which option
caused the problem.  The patch changes the message to:

    qemu: --monitor stdio: Duplicate ID 'compat_monitor0' for mon

monitor_parse() is also used for creating a default monitor, but
that's not done when the user specifies a monitor, so an ID clash is
impossible then.

8e8cb375e0 block: Give always priority to unused entries in the qcow2 L2 cache
The current algorithm to replace entries from the L2 cache gives
priority to newer hits by dividing the hit count of all existing
entries by two everytime there is a cache miss.

However, if there are several cache misses the hit count of the
existing entries can easily go down to 0. This will result in those
entries being replaced even when there are others that have never been
used.

This problem is more noticeable with larger disk images and cache
sizes, since the chances of having several misses before the cache is
full are higher.

If we make sure that the hit count can never go down to 0 again,
unused entries will always have priority.

fa21e6faa6 nbd: fix max_discard/max_transfer_length
nbd_co_discard calls nbd_client_session_co_discard which uses uint32_t
as the length in bytes of the data to discard due to the following
definition:

struct nbd_request {
    uint32_t magic;
    uint32_t type;
    uint64_t handle;
    uint64_t from;
    uint32_t len; <-- the length of data to be discarded, in bytes
} QEMU_PACKED;

Thus we should limit bl_max_discard to UINT32_MAX >> BDRV_SECTOR_BITS to
avoid overflow.

NBD read/write code uses the same structure for transfers. Fix
max_transfer_length accordingly.

1ce52846d3 nbd: Improve error messages
This patch makes use of the Error object for nbd_receive_negotiate() so
that errors during negotiation look nicer.

Furthermore, this patch adds an additional error message if the received
magic was wrong, but would be correct for the other protocol version,
respectively: So if an export name was specified, but the NBD server
magic corresponds to an old handshake, this condition is explicitly
signaled to the user, and vice versa.

As these messages are now part of the "Could not open image" error
message, additional filtering has to be employed in iotest 083, which
this patch does as well.

a231cb2726 iotests: Fix 104 for NBD
_make_test_img sets up an NBD server, _cleanup_test_img shuts it down;
thus, _cleanup_test_img has to be called before _make_test_img is
invoked another time.

Furthermore, the pipe through _filter_test_img was unnecessary;
_make_test_img already takes care of that.

And finally, a filter is added to _filter_img_info to replace
"nbd://127.0.0.1:10810" by "TEST_DIR/t.IMGFMT", since the former is the
way to express the full image path (normally the latter) for NBD tests.

53f9e77f4e iotests: Fix 083
As of 8f9e835fd2, probing should be
disabled in the qemu-iotests (at least when using qemu-io). This broke
083's reference output (which consisted mostly of "Could not read image
for determining its format").

This patch fixes it.

Note that one case which failed before is now successful: Disconnect
after data. This is due to qemu having read twice before (once for
probing, once for the qemu-io read command), but only once now (the
qemu-io read command). Therefore, reading is successful (which is

6b383c08c4 block/dmg: support bzip2 block entry types
This patch adds support for bzip2-compressed block entries as introduced
with OS X 10.4 (source: https://en.wikipedia.org/wiki/Apple_Disk_Image).

It was tested against a 5.2G "OS X Yosemite" installation image which
stores the BLXX block in the XML property list (instead of resource
forks) and has over 5k chunks.

New configure entries are added (--enable-bzip2 / --disable-bzip2) to
control inclusion of bzip2 functionality (which requires linking against
libbz2). The help message suggests that this option is needed for DMG
files, but the tests are generic enough that other parts of QEMU can use
bzip2 if needed.

The identifiers are based on http://newosxbook.com/DMG.html.

The decompression routines are based on the zlib case, but as there is
no way to reset the decompression state (unlike zlib), memory is
allocated and deallocated for every decompression. This should not be
problematic as the decompression takes most of the time and as blocks
are typically about/over 1 MiB in size, only one allocation is done
every 2000 sectors.

66ec3bba97 block/dmg: use SectorNumber from BLKX header
Previously the sector table parsing relied on the previous offset of
the DMG file. Now it uses the sector number from the BLKX header
(see http://newosxbook.com/DMG.html).

The implementation of dmg2img (from vu1tur) does not base the output
sector on the location of the terminator (0xffffffff) either so it
should be safe to drop this dependency on the previous state.

(It makes somehow makes sense, a terminator should halt further
processing of a block and is perhaps used to preallocate some space.)

c6d34865fa block/dmg: fix sector data offset calculation
This patch addresses two issues:

 - The data fork offset was not taken into account, resulting in failure
   to read an InstallESD.dmg file (5164763151 bytes) which had a
   non-zero DataForkOffset field.
 - The offset of the previous block ("partition") was unconditionally
   added to the current block because older files would start the input
   offset of a new block at zero. Newer files (including vlc-2.1.5.dmg,
   tuxpaint-0.9.15-macosx.dmg and OS X Yosemite [MAS].dmg) failed in
   reads because these files have chunk offsets, relative to the begin
   of a data fork.

Now the data offset of the mish is taken into account. While we could
check that the data_offset is within the data fork, let's not do that
here as it would only result in parse failures on invalid files (rather
than gracefully handling such bad files). dmg_read will error out if
the offset is incorrect.

Right now the virtual size is always reported as zero which makes it

To verify the behavior, the output of `dmg2img foo.dmg foo.img` was

tests showed that the file contents are exactly the same, except that
QEMU creates a slightly larger file (it matches the total sectors

0599e56ed4 block/dmg: process XML plists
The format is simple enough to avoid using a full-blown XML parser. It
assumes that all BLKX items begin with the "mish" magic word, therefore
it is not a problem if other values get matched which are not a BLKX
block.

The offsets are based on the description at
http://newosxbook.com/DMG.html

For compatibility with glib 2.12, use g_base64_decode (which
additionally requires an extra buffer allocation) instead of
g_base64_decode_inplace (which is only available since glib 2.20).

f6e6652d7c block/dmg: validate chunk size to avoid overflow
Previously the chunk size was not checked, allowing for a large memory
allocation. This patch checks whether the chunks size is within the
resource fork length, and whether the resource fork is below the
trailer of the dmg file.

7aee37b93a block/dmg: process a buffer instead of reading ints
As the decoded plist XML is not a pointer in the file,
dmg_read_mish_block must be able to process a buffer instead of a file
pointer. Since the full buffer must be processed, let's change the
return value again to just a success flag.
