2017-03-16vmstate: fix failed iotests case 68 and 91QingFeng Hao
This problem affects s390x only if we are running without KVM. Basically, S390CPU.irqstate is unused if we do not use KVM, and thus no buffer is allocated. This causes size=0, first_elem=NULL and n_elems=1 in vmstate_load_state and vmstate_save_state. And the assert fails. With this fix we can go back to the old behavior and support VMS_VBUFFER with size 0 and nullptr.

2017-03-16cirrus: stop passing around src pointers in the blitterGerd Hoffmann
Does basically the same as "cirrus: stop passing around dst pointers in the blitter", just for the src pointer instead of the dst pointer. For the src we have to care about cputovideo blits though and fetch the data from s->cirrus_bltbuf instead of vga memory. The cirrus_src*() helper functions handle that.

2017-03-16cirrus: add option to disable blitterGerd Hoffmann
Ok, we have this beast in the cirrus code which is not used at all by modern guests, except when you try to find security holes in qemu. So, add an option to disable blitter altogether. Guests released within the last ten years should not show any rendering issues if you turn off blitter support. There are no known bugs in the cirrus blitter code. But in the past we hoped a few times already that we've finally nailed the last issue. So having some easy way to mitigate in case yet another blitter issue shows up certainly makes me sleep a bit better at night. For completeness: The by far better way to mitigate is to switch away from cirrus and use stdvga instead. Or something more modern like virtio-vga in case your guest has support for it.

2017-03-16cirrus: switch to 4 MB video memory by defaultGerd Hoffmann
Quoting cirrus source code: Follow real hardware, cirrus card emulated has 4 MB video memory. Also accept 8 MB/16 MB for backward compatibility. So just use 4MB by default. We decided to leave that at 8MB by default a while ago, for live migration compatibility reasons. But we have compat properties to handle that, so that isn't a compeling reason. This also removes some sanity check inconsistencies in the cirrus code. Some places check against the allocated video memory, some places check against the 4MB physical hardware has. Guest code can trigger asserts because of that. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 1489494514-15606-1-git-send-email-kraxel@redhat.com
2017-03-16cirrus/vnc: zap bitblit support from console code.Gerd Hoffmann
There is a special code path (dpy_gfx_copy) to allow graphic emulation notify user interface code about bitblit operations carryed out by guests. It is supported by cirrus and vnc server. The intended purpose is to optimize display scrolls and just send over the scroll op instead of a full display update. This is rarely used these days though because modern guests simply don't use the cirrus blitter any more. Any linux guest using the cirrus drm driver doesn't. Any windows guest newer than winxp doesn't ship with a cirrus driver any more and thus uses the cirrus as simple framebuffer. So this code tends to bitrot and bugs can go unnoticed for a long time. See for example commit "3e10c3e vnc: fix qemu crash because of SIGSEGV" which fixes a bug lingering in the code for almost a year, added by commit "c7628bf vnc: only alloc server surface with clients connected". Also the vnc server will throttle the frame rate in case it figures the network can't keep up (send buffers are full). This doesn't work with dpy_gfx_copy, for any copy operation sent to the vnc client we have to send all outstanding updates beforehand, otherwise the vnc client might run the client side blit on outdated data and thereby corrupt the display. So this dpy_gfx_copy "optimization" might even make things worse on slow network links. Lets kill it once for all. Oh, and one more reason: Turns out (after writing the patch) we have a security bug in that code path ...

2017-03-16migration: use "" as the default for tls-creds/hostnameDaniel P. Berrange
The tls-creds parameter has a default value of NULL indicating that TLS should not be used. Setting it to non-NULL enables use of TLS. Once tls-creds are set to a non-NULL value via the monitor, it isn't possible to set them back to NULL again, due to current implementation limitations. The empty string is not a valid QObject identifier, so this switches to use "" as the default, indicating that TLS will not be used The tls-hostname parameter has a default value of NULL indicating the the hostname from the migrate connection URI should be used. Again, once tls-hostname is set non-NULL, to override the default hostname for x509 cert validation, it isn't possible to reset it back to NULL via the monitor. The empty string is not a valid hostname, so this switches to use "" as the default, indicating that the migrate URI hostname should be used. Using "" as the default for both, also means that the monitor commands "info migrate_parameters" / "query-migrate-parameters" will report existance of tls-creds/tls-parameters even when set to their default values.

For example: When ram_list.dirty_memory[DIRTY_MEMORY_MIGRATION] = 0b00001111, and atomic_rcu_read(&migration_bitmap_rcu)->bmap = 0b00000011, the new_dirty will be 0b00001100, and this function will return 2 but not 4 which is expected. the dirty pages in dirty_memory[DIRTY_MEMORY_MIGRATION] are all new, so these should be calculated also.

2017-03-16qapi: The #optional tag is redundant, dropMarkus Armbruster
We traditionally mark optional members #optional in the doc comment. Before commit 3313b61, this was entirely manual. Commit 3313b61 added some automation because its qapi2texi.py relied on #optional to determine whether a member is optional. This is no longer the case since the previous commit: the only thing qapi2texi.py still does with #optional is stripping it out. We still reject bogus qapi-schema.json and six places for qga/qapi-schema.json. Thus, you can't actually rely on #optional to see whether something is optional. Yet we still make people add it manually. That's just busy-work. Drop the code to check, fix up and strip out #optional, along with all instances of #optional. To keep it out, add code to reject it, to be dropped again once the dust settles. No change to generated documentation.

2017-03-16qapi2texi: Convert to QAPISchemaVisitorMarkus Armbruster
qapi2texi works with schema expression trees. Such a tight coupling to schema language syntax is not a good idea. Convert it to the visitor interface the other generators use.

2017-03-16qapi: Conjure up QAPIDoc.ArgSection for undocumented membersMarkus Armbruster
qapi2texi.py already conjures up ArgSections for undocumented enumeration values, in texi_enum. Drop that, and conjure them up for all kinds of "arguments" (enumeration values, object and alternate type members) in qapi.py instead. Take care to keep generated documentation exactly the same for now.

2017-03-16qapi: Prepare for requiring more complete documentationMarkus Armbruster
We currently neglect to check all enumeration values, common members of object types and members of alternate types are documented. Unsurprisingly, many aren't. Add the necessary plumbing to find undocumented ones, except for variant members of object types. Don't enforce anything just yet, but connect each QAPIDoc.ArgSection to its QAPISchemaMember.

2017-03-16qapi: Avoid unwanted blank lines in QAPIDocMarkus Armbruster
We silently fix missing #optional tags for QAPIDoc by appending a line "#optional" to the section's .content. However, this interferes with .__repr__ stripping trailing blank lines from .content. Use new ArgSection instance variable .optional instead, and leave .content alone. To permit testing .optional in texi_body(), clean up texi_enum()'s hack to add empty documentation for undocumented enum values: add an ArgSection instead of ''.
