Paul Durrant	19b845bda8	MAINTAINERS: add myself as a Xen maintainer I have made many significant contributions to the Xen code in QEMU, particularly the recent patches introducing a new PV device framework. I intend to make further significant contributions, porting other PV back- ends to the new framework with the intent of eventually removing the legacy code. It therefore seems reasonable that I become a maintainer of the Xen code.

Paul Durrant	db9ff46eeb	xen: automatically create XenBlockDevice-s This patch adds create and destroy function for XenBlockDevice-s so that they can be created automatically when the Xen toolstack instantiates a new PV backend via xenstore. When the XenBlockDevice is created this way it is also necessary to create a 'drive' which matches the configuration that the Xen toolstack has written into xenstore. This is done by formulating the parameters necessary for each 'blockdev' layer of the drive and then using qmp_blockdev_add() to create the layers. Also, for compatibility with the legacy 'xen_disk' implementation, an iothread is automatically created for the new XenBlockDevice. This, like the driver layers, will be destroyed after the XenBlockDevice is unrealized. The legacy backend scan for 'qdisk' is removed by this patch, which makes the 'xen_disk' code is redundant. The code will be removed by a subsequent patch.

Paul Durrant	a783f8ad4e	xen: add a mechanism to automatically create XenDevice-s... ...that maintains compatibility with existing Xen toolstacks. Xen toolstacks instantiate PV backends by simply writing information into xenstore and expecting a backend implementation to be watching for this. This patch adds a new 'xen-backend' module to allow individual XenDevice implementations to register create and destroy functions. The creator will be called when a tool-stack instantiates a new backend in this way, and the destructor will then be called after the resulting XenDevice object is unrealized. To support this it is also necessary to add new watchers into the XenBus implementation to handle enumeration of new backends and also destruction of XenDevice-s when the toolstack sets the backend 'online' key to 0. NOTE: This patch only adds the framework. A subsequent patch will add a creator function for xen-block devices.

Paul Durrant	4ea7d1a7f1	xen: duplicate xen_disk.c as basis of dataplane/xen-block.c The new xen-block XenDevice implementation requires the same core dataplane as the legacy xen_disk implementation it will eventually replace. This patch therefore copies the legacy xen_disk.c source module into a new dataplane/xen-block.c source module as the basis for the new dataplane and adjusts the MAINTAINERS file accordingly. NOTE: The duplicated code is not yet built. It is simply put into place by this patch (just fixing style violations) such that the modifications that will need to be made to the code are not conflated with code movement, thus making review harder.

Paul Durrant	82a29e3048	xen: add xenstore watcher infrastructure A Xen PV frontend communicates its state to the PV backend by writing to the 'state' key in the frontend area in xenstore. It is therefore necessary for a XenDevice implementation to be notified whenever the value of this key changes. This patch adds code to do this as follows: - an 'fd handler' is registered on the libxenstore handle which will be triggered whenever a 'watch' event occurs - primitives are added to xen-bus-helper to add or remove watch events - a list of Notifier objects is added to XenBus to provide a mechanism to call the appropriate 'watch handler' when its associated event occurs The xen-block implementation is extended with a 'frontend_changed' method, which calls as-yet stub 'connect' and 'disconnect' functions when the relevant frontend state transitions occur. A subsequent patch will supply a full implementation for these functions.

Paul Durrant	094a22399f	xen: create xenstore areas for XenDevice-s This patch adds a new source module, xen-bus-helper.c, which builds on basic libxenstore primitives to provide functions to create (setting permissions appropriately) and destroy xenstore areas, and functions to 'printf' and 'scanf' nodes therein. The main xen-bus code then uses these primitives [1] to initialize and destroy the frontend and backend areas for a XenDevice during realize and unrealize respectively. The 'xen-block' implementation is extended with a 'get_name' method that returns the VBD number. This number is required to 'name' the xenstore areas. NOTE: An exit handler is also added to make sure the xenstore areas are cleaned up if QEMU terminates without devices being unrealized. [1] The 'scanf' functions are actually not yet needed, but they will be needed by code delivered in subsequent patches.

Paul Durrant	1a72d9ae31	xen: introduce 'xen-block', 'xen-disk' and 'xen-cdrom' This patch adds new XenDevice-s: 'xen-disk' and 'xen-cdrom', both derived from a common 'xen-block' parent type. These will eventually replace the 'xen_disk' (note the underscore rather than hyphen) legacy PV backend but it is illustrative to build up the implementation incrementally, along with the XenBus/XenDevice framework. Subsequent patches will therefore add to these devices' implementation as new features are added to the framework. After this patch has been applied it is possible to instantiate new 'xen-disk' or 'xen-cdrom' devices with a single 'vdev' parameter, which accepts values adhering to the Xen VBD naming scheme [1]. For example, a command-line instantiation of a xen-disk can be done with an argument similar to the following: -device xen-disk,vdev=hda The implementation of the vdev parameter formulates the appropriate VBD number for use in the PV protocol.

Peter Maydell	6c4f984463	hw/xen/xen_pt_graphics: Don't trust the BIOS ROM contents so much Coverity (CID 796599) points out that xen_pt_setup_vga() trusts the rom->size field in the BIOS ROM from a PCI passthrough VGA device, and uses it as an index into the memory which contains the BIOS image. A corrupt BIOS ROM could therefore cause us to index off the end of the buffer. Check that the size is within bounds before we use it. We are also trusting the pcioffset field, and assuming that the whole rom_header is present; Coverity doesn't notice these, but check them too.

Paolo Bonzini	eae3eb3e18	qemu/queue.h: simplify reverse access to QTAILQ The new definition of QTAILQ does not require passing the headname, remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	8 years ago
Paolo Bonzini	7274f01bb8	qemu/queue.h: reimplement QTAILQ without pointer-to-pointers QTAILQ is a doubly linked list, with a pointer-to-pointer to the last element from the head, and the previous element from each node. But if you squint enough, QTAILQ becomes a combination of a singly-linked forwards list, and another singly-linked list which goes backwards and is circular. This is the idea that lets QTAILQ implement reverse iteration: only, because the backwards list points inside the node, accessing the previous element needs to go two steps back and one forwards. What this patch does is implement it in these terms, without actually changing the in-memory layout at all. The coexistence of the two lists is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in both directions; the union is needed so that the forwards pointer can have the correct type, as a sort of poor man's template. While there are other ways to get the same layout without a union, this one has the advantage of simpler operation in the debugger, because the fields tqh_first and tqe_next still exist as before the patch. Those fields are also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them. The advantage of the new representation is that the two-back-one-forward dance done by backwards accesses can be done all while operating on QTailQLinks. No casting to the head struct is needed anymore because, even though the QTailQLink's forward pointer is a void *, we can use typeof to recover the correct type. This patch only changes the implementation, not the interface. The next patch will remove the head struct name from the backwards visit macros.

Paolo Bonzini	f481ee2d5e	qemu/queue.h: typedef QTAILQ heads This will be needed when we change the QTAILQ head and elem structs to unions. However, it is also consistent with the usage elsewhere in QEMU for other list head structs (see for example FsMountList). Note that most QTAILQs only need their name in order to do backwards walks. Those do not break with the struct->union change, and anyway the change will also remove the need to name heads when doing backwards walks, so those are not touched here.

Paolo Bonzini	9df43317b8	test: replace gtester with a TAP driver gtester is deprecated by upstream glib (see for example the announcement at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does not support tests that call g_test_skip in some glib stable releases. glib suggests instead using Automake's TAP support, which gtest itself supports since version 2.38 (QEMU's minimum requirement is 2.40). We do not support Automake, but we can use Automake's code to beautify the TAP output. I chose to use the Perl copy rather than the shell/awk one, with some changes so that it can accept TAP through stdin, in order to reuse Perl's TAP parsing package. This also avoids duplicating the parser between tap-driver.pl and tap-merge.pl.

Marc-André Lureau	4ac8086647	qga: drop < Vista compatibility Building QGA for XP seems possible so far: the dependency on libqemuutil.a implies building qemu-thread-win32.c, which requires Vista API since commit `12f8def0` (v2.9). But qemu-thread isn't being used in QGA, the resulting binary may still work on XP. XP is no longer supported for the past 4.5y, it's time to drop support for it.

Marc-André Lureau	56cdca1d7a	build-sys: build with Vista API by default Both qemu & qga build with Vista API by default already, by defining _WIN32_WINNT 0x0600. Set it globally in osdep.h instead. This replaces WINVER by _WIN32_WINNT in osdep.h. WINVER doesn't seem to be really useful these days.

Marc-André Lureau	007e722c34	build-sys: move windows defines in osdep.h header This removes some clutter in compilation logging, and allows some easier tweaking per compilation unit/CFLAGS overriding. Note that we can't move those define in os-win32.h, since they must be set before the first system headers are included.

Guenter Roeck	ea84a44250	scsi: esp: Defer command completion until previous interrupts have been handled The guest OS reads RSTAT, RSEQ, and RINTR, and expects those registers to reflect a consistent state. However, it is possible that the registers can change after RSTAT was read, but before RINTR is read, when esp_command_complete() is called. Guest OS qemu -------- ---- [handle interrupt] Read RSTAT esp_command_complete() RSTAT = STAT_ST esp_dma_done() RSTAT \|= STAT_TC RSEQ = 0 RINTR = INTR_BS Read RSEQ Read RINTR RINTR = 0 RSTAT &= ~STAT_TC RSEQ = SEQ_CD The guest OS would then try to handle INTR_BS combined with an old value of RSTAT. This sometimes resulted in lost events, spurious interrupts, guest OS confusion, and stalled SCSI operations. A typical guest error log (observed with various versions of Linux) looks as follows. scsi host1: Spurious irq, sreg=13. ... scsi host1: Aborting command [84531f10:2a] scsi host1: Current command [f882eea8:35] scsi host1: Queued command [84531f10:2a] scsi host1: Active command [f882eea8:35] scsi host1: Dumping command log scsi host1: ent[15] CMD val[44] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[00] event[0c] scsi host1: ent[16] CMD val[01] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[17] CMD val[43] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[18] EVENT val[0d] sreg[92] seqreg[04] sreg2[00] ireg[18] ss[00] event[0c] ...
