Specifying the image filename through the "file" option is a legacy option and should not be supported by blockdev-add (in that case, giving a string for "file" references an existing block device).

It should be possible to use a format as a driver for a file which in turn requires another file, i.e., nesting file formats. Allowing nested file formats results in e.g. qcow2 BlockDriverStates never being directly passed to bdrv_open_common() from bdrv_file_open(), but instead being handed through bdrv_open(). This changes the error message when trying to give a filename to qcow2, i.e. trying to use it as a driver for the protocol level. Therefore, change the reference output of I/O test 051 accordingly.

Add a common function for opening images to be used for block drivers specified through BlockdevRefs in an option QDict. The difference from bdrv_file_open() is that this function may invoke bdrv_open() instead, allowing auto-detection of the driver to be used; and second, it automatically extracts the BlockdevRef from the option QDict.

blkdebug and blkverify will, in order to retain compatibility, not support the field "file" implicitly through bdrv_open(). In order to be able to use those drivers without giving a filename anyway, it is necessary to be able to have block devices without files implicitly opened by bdrv_open(). This is the case, if there was neither a file name, a reference to an existing block device to use as a file nor options specific to the file.

This function basically parses command-line options given as a QDict replacing a config file. For instance, the QDict {"section.opt1": 42, "section.opt2": 23} corresponds to the config file: [section] opt1 = 42 opt2 = 23 It is possible to specify multiple sections and also multiple sections of the same type. On the command line, this looks like the following: inject-error.0.event=reftable_load,\ inject-error.1.event=l2_load,\ set-state.event=l1_update This would correspond to the following config file: [inject-error "inject-error.0"] event = reftable_load [inject-error "inject-error.1"] event = l2_load [set-state] event = l1_update Signed-off-by: NMax Reitz <mreitz@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Reversing qdict_array_split(), qdict_flatten() should flatten QLists as well by interpreting them as QDicts where every entry's key is its index. This allows bringing QDicts with QLists from QMP commands to the same form as they would be given as command-line options, thereby allowing them to be parsed the same way.

If the filename is not prefixed by "blkdebug:" in blkdebug_parse_filename(), the blkdebug driver was not selected through that protocol prefix, but by an explicit command line option (file.driver=blkdebug or something similar). Contrary to the current reaction, this is not a problem at all; we just need to store the filename (in the x-image option) and can go on; the user just has to manually specify the config option.

Make the readline.c functionality reusable. Instead of calling monitor_printf() and monitor_flush() directly, invoke function pointers provided by the user. This way readline.c does not know about Monitor and other users will be able to make use of readline.c. Note that there is already an "opaque" argument to the ReadLineFunc callback. Consistently call it "readline_opaque" from now on to distinguish from the ReadLinePrintfFunc/ReadLineFlushFunc "opaque" argument. I also dropped the printf macro trickery since it's now highly unlikely that anyone modifying readline.c would call printf(3) directly. We no longer need this protection.

GlusterFS supports creation of zero-filled file on GlusterFS volume by means of an API called glfs_zerofill(). Use this API from QEMU to create an image that is filled with zeroes by using the preallocation option of qemu-img. qemu-img create gluster://server/volume/image -o preallocation=full 10G The allowed values for preallocation are 'full' and 'off'. By default preallocation is off and image is not zero-filled. glfs_zerofill() offloads the writing of zeroes to the server and if the storage supports SCSI WRITESAME, GlusterFS server can issue BLKZEROOUT ioctl to achieve the zeroing.

rbd callbacks are called from non-QEMU threads. Up until now a pipe was used to signal completion back to the QEMU iothread. The pipe writer code handles EAGAIN using select(2). The select(2) API is not scalable since fd_set size is static. FD_SET() can write beyond the end of fd_set if the file descriptor number is too high. (QEMU's main loop uses poll(2) to avoid this issue with select(2).) Since the pipe itself is quite clumsy to use and QEMUBH is now thread-safe, just schedule a BH from the rbd callback function. This way we can simplify I/O completion in addition to eliminating the potential FD_SET() crash when file descriptor numbers become too high. Crash scenario: QEMU already has 1024 file descriptors open. Hotplug an rbd drive and get the pipe writer to take the select(2) code path.

Use fprintf(stderr instead. This removes dependency of libqemuutil.a on the monitor. We can further justify this change, in that this code path should only trigger under a fatal error condition. fprintf-stderr is probably the appropriate medium as under a fatal error conidition the monitor itself may be down and out for the count. So assertion failure messages should go lowest common denominator - straight to stderr. Fixes the build as reported by Kevin Wolf. Issue debugged and change suggested by Luiz Capitulino.
