2018-11-01chardev/char-socket: Function headers refactoringJulia Suvorova
Upcoming websocket support requires additional parameters in function headers that are already overloaded. This patch replaces the bunch of parameters with a single structure pointer.

2018-11-01char-socket: make 'fd' incompatible with 'reconnect'Marc-André Lureau
A chardev socket created with the 'fd=' argument is not going to handle reconnection properly by recycling the same fd (or not in a supported way). Let's forbid this case. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P. Berrangé <berrange@redhat.com>
2018-11-01char-socket: correctly set has_reconnect when parsing QemuOptsMarc-André Lureau
qemu_chr_parse_socket() fills all ChardevSocket fields, but that doesn't reflect correctly the arguments given with the options / on the command line. "reconnect" takes a number as argument, and the default value is 0, which doesn't help to identify the missing option. The other arguments have default values that are less problematic, leave them set by default for now. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Daniel P.

Before previous patch, iotest 169 was actually broken for the case test_persistent__not_migbitmap__offline_shared, while formally passing. After migration log of vm_b had message: qemu-system-x86_64: Could not reopen qcow2 layer: Bitmap already exists: bitmap0 which means that invalidation failed and bs->drv = NULL. It was because we've loaded bitmap twice: on open and on invalidation. Add code to 169, to catch such fails.

2018-10-29dirty-bitmaps: clean-up bitmaps loading and migration logicVladimir Sementsov-Ogievskiy
This patch aims to bring the following behavior: 1. We don't load bitmaps, when started in inactive mode. It's the case of incoming migration. In this case we wait for bitmaps migration through migration channel (if 'dirty-bitmaps' capability is enabled) or for invalidation (to load bitmaps from the image). 2. We don't remove persistent bitmaps on inactivation. Instead, we only remove bitmaps after storing. This is the only way to restore bitmaps, if we decided to resume source after [failed] migration with 'dirty-bitmaps' capability enabled (which means, that bitmaps were not stored). 3. We load bitmaps on open and any invalidation, it's ok for all cases: - normal open - migration target invalidation with dirty-bitmaps capability (bitmaps are migrating through migration channel, the are not stored, so they should have IN_USE flag set and will be skipped when loading. However, it would fail if bitmaps are read-only[1]) - migration target invalidation without dirty-bitmaps capability (normal load of the bitmaps, if migrated with shared storage) - source invalidation with dirty-bitmaps capability (skip because IN_USE) - source invalidation without dirty-bitmaps capability (bitmaps were dropped, reload them) [1]: to accurately handle this, migration of read-only bitmaps is explicitly forbidden in this patch. New mechanism for not storing bitmaps when migrate with dirty-bitmaps capability is introduced: migration filed in BdrvDirtyBitmap.

2018-10-29bitmap: Update count after a mergeEric Blake
We need an accurate count of the number of bits set in a bitmap after a merge. In particular, since the merge operation short-circuits a merge from an empty source, if you have bitmaps A, B, and C where B started empty, then merge C into B, and B into A, an inaccurate count meant that A did not get the contents of C. In the worst case, we may falsely regard the bitmap as empty when it has had new writes merged into it.

2018-10-29spice: prepare for upcoming spice-server changeGerd Hoffmann
Future spice-server versions will call the client_monitors_config callback with the monitors list filtered to only include the monitors of the given display channel (aka QXLInstance). Luckily this is easily detectable at runtime, so we can prepare for that in advance and also make qemu compatible with both old and new spice-server versions. While being at it also use the console index instead of head number as array index. The later doesn't work correctly in case multiple display devices are present.
