2020-05-19qemu-img: Add bitmap sub-commandEric Blake3-0/+279
Include actions for --add, --remove, --clear, --enable, --disable, and --merge (note that --clear is a bit of fluff, because the same can be accomplished by removing a bitmap and then adding a new one in its place, but it matches what QMP commands exist). Listing is omitted, because it does not require a bitmap name and because it was already possible with 'qemu-img info'. A single command line can play one or more bitmap commands in sequence on the same bitmap name (although all added bitmaps share the same granularity, and and all merged bitmaps come from the same source file). Merge defaults to other bitmaps in the primary image, but can also be told to merge bitmaps from a distinct image. While this supports --image-opts for the file being modified, I did not think it worth the extra complexity to support that for the source file in a cross-file merges. Likewise, I chose to have --merge only take a single source rather than following the QMP support for multiple merges in one go (although you can still use more than one --merge in the command line); in part because qemu-img is offline and therefore atomicity is not an issue. Upcoming patches will add iotest coverage of these commands while also testing other features.

2020-05-19blockdev: Split off basic bitmap operations for qemu-imgEric Blake5-286/+324
Upcoming patches want to add some basic bitmap manipulation abilities to qemu-img. But blockdev.o is too heavyweight to link into qemu-img (among other things, it would drag in block jobs and transaction support - qemu-img does offline manipulation, where atomicity is less important because there are no concurrent modifications to compete with), so it's time to split off the bare bones of what we will need into a new file block/monitor/bitmap-qmp-cmds.o. This is sufficient to expose 6 QMP commands for use by qemu-img (add, remove, clear, enable, disable, merge), as well as move the three helper functions touched in the previous patch. Regarding MAINTAINERS, the new file is automatically part of block core, but also makes sense as related to other dirty bitmap files.

2020-05-19blockdev: Promote several bitmap functions to non-staticEric Blake2-28/+31
The next patch will split blockdev.c, which will require accessing some previously-static functions from more than one .c file. But part of promoting a function to public is picking a naming scheme that does not reek of exposing too many internals (two of the three functions were named starting with 'do_'). To make future code motion easier, perform the function rename and non-static promotion into its own patch.

2020-05-19block: Make it easier to learn which BDS support bitmapsEric Blake6-0/+21
Upcoming patches will enhance bitmap support in qemu-img, but in doing so, it turns out to be nice to suppress output when persistent bitmaps make no sense (such as on a qcow2 v2 image). Add a hook to make this easier to query. This patch adds a new callback .bdrv_supports_persistent_dirty_bitmap, rather than trying to shoehorn the answer in via existing callbacks. In particular, while it might have been possible to overload .bdrv_co_can_store_new_dirty_bitmap to special-case a NULL input to answer whether any persistent bitmaps are supported, that is at odds with whether a particular bitmap can be stored (for example, even on an image that supports persistent bitmaps but has currently filled up the maximum number of bitmaps, attempts to store another one should fail); and the new functionality doesn't require coroutine safety. Similarly, we could have added one more piece of information to .bdrv_get_info, but then again, most callers to that function tend to already discard extraneous information, and making it a catch-all rather than a series of dedicated scalar queries hasn't really simplified life. In the future, when we improve the ability to look up bitmaps through a filter, we will probably also want to teach the block layer to automatically let filters pass this request on through.

2020-05-19bitmaps: Update maintainerEric Blake1-3/+4
Dirty bitmaps are important to incremental backups, including exposure over NBD where I'm already maintainer. Also, I'm aware that lately I have been doing as much code/review on bitmaps as John Snow who is trying to scale back in order to focus elsewhere; and many of the recent patches have come from Vladimir, who is also interested in taking on maintainer duties, but would like to start with co-maintainership. Therefore, it's time to revamp the ownership of this category, as agreed between the three of us.

2020-05-18aio-posix: disable fdmon-io_uring when GSource is usedStefan Hajnoczi4-0/+20
The glib event loop does not call fdmon_io_uring_wait() so fd handlers waiting to be submitted build up in the list. There is no benefit is using io_uring when the glib GSource is being used, so disable it instead of implementing a more complex fix. This fixes a memory leak where AioHandlers would build up and increasing amounts of CPU time were spent iterating them in aio_pending(). The symptom is that guests become slow when QEMU is built with io_uring support.

2020-05-18aio-posix: don't duplicate fd handler deletion in fdmon_io_uring_destroy()Stefan Hajnoczi2-3/+11
The io_uring file descriptor monitoring implementation has an internal list of fd handlers that are pending submission to io_uring. fdmon_io_uring_destroy() deletes all fd handlers on the list. Don't delete fd handlers directly in fdmon_io_uring_destroy() for two reasons: 1. This duplicates the aio-posix.c AioHandler deletion code and could become outdated if the struct changes. 2. Only handlers with the FDMON_IO_URING_REMOVE flag set are safe to remove. If the flag is not set then something still has a pointer to the fd handler. Let aio-posix.c and its user worry about that. In practice this isn't an issue because fdmon_io_uring_destroy() is only called when shutting down so all users have removed their fd handlers, but the next patch will need this!

2020-05-18iotests/030: Reduce run time by unthrottling job earlierKevin Wolf1-3/+3
test_overlapping_3() throttles its active commit job so it can be sure the job is still busy when it checks that you can't start a conflicting streaming job. However, it only sets the commit job back to full speed when it is ready, which takes a few seconds while it's throttled. We can already reset the limit after having checked that block-stream returns an error and save these seconds.
