2023-11-08block: Protect bs->file with graph_lockKevin Wolf
Almost all functions that access bs->file already take the graph lock now. Add locking to the remaining users and finally annotate the struct field itself as protected by the graph lock.

2023-11-08block: Take graph lock for most of .bdrv_openKevin Wolf
Most implementations of .bdrv_open first open their file child (which is an operation that internally takes the write lock and therefore we shouldn't hold the graph lock while calling it), and afterwards many operations that require holding the graph lock, e.g. for accessing bs->file. This changes block drivers that follow this pattern to take the graph lock after opening the child node.

2023-11-08block: Add missing GRAPH_RDLOCK annotationsKevin Wolf
This adds GRAPH_RDLOCK to some driver callbacks that are already called with the graph lock held, and which will need the annotation because they access bs->file, but don't have it yet. This also covers a few callbacks that were not marked GRAPH_RDLOCK before, but where updating BlockDriver is trivially possible.

2023-11-08block: Introduce bdrv_co_change_backing_file()Kevin Wolf
bdrv_change_backing_file() is called both inside and outside coroutine context. This makes it difficult for it to take the graph lock internally. It also means that driver implementations need to be able to run outside of coroutines, too. Switch it to the usual model with a coroutine based implementation and a co_wrapper instead. The new function is marked GRAPH_RDLOCK. As the co_wrapper now runs the function in the AioContext of the node (as it should always have done), this is not GLOBAL_STATE_CODE() any more.

2023-11-08blkverify: Add locking for request_fnKevin Wolf
This is either bdrv_co_preadv() or bdrv_co_pwritev() which both need to have the graph locked. Annotate the function pointer accordingly and add locking to its callers. This shouldn't actually have resulted in a bug because the graph lock is already held by blkverify_co_prwv(), which waits for the coroutines to terminate. Annotate with GRAPH_RDLOCK as well to make this clearer.

git://git.infradead.org/users/dwmw2/qemu into staging Xen PV guest support for 8.2 Add Xen PV console and network support, the former of which enables the Xen "PV shim" to be used to support PV guests. Also clean up the block support and make it work when the user passes just 'drive file=IMAGE,if=xen' on the command line. Update the documentation to reflect all of these, taking the opportunity to simplify what it says about q35 by making unplug work for AHCI. Ignore the VCPU_SSHOTTMR_future timer flag, and advertise the 'fixed' per-vCPU upcall vector support, as newer upstream Xen do. # -----BEGIN PGP SIGNATURE----- # # iQJIBAABCAAyFiEEvgfZ/VSAmrLEsP9fY3Ys2mfi81kFAmVJ/7EUHGR3bXcyQGlu # ZnJhZGVhZC5vcmcACgkQY3Ys2mfi81k+/xAAswivVR4+nwz3wTSN7EboGogS3hy+ # ZsTpvbJnfprGQJAK8vv8OP4eunaCJkO/dy3M/33Dh270msmV6I/1ki0E1RIPG45D # n5wKM1Zxk0ABvjIgdp3xiLwITTdruJ+k9aqV8U9quhjgNFdOa7yjBOG8MD32GEPZ # KHbavJ++huOu7+DZHJRNRq4gI/fREIULoPGHVg7WuEiRDYokOOmMROXqmTHTaUkV # yFhkofzWxlpYhh7qRQx6/A80CSf7xwCof8krjdMCOYj3XGzYVZND0z5ZfHQYEwqt # fowhargA8gH4V3d21S/MWCaZ+QrswFXZhcnl5wuGgWakV4ChvFETKs+fz2mODWUx # 2T13trqeFJ5ElTrSpH1iWCoSEy6KCeLecvx7c/6HPSkDYQ3w5q8dXPpqgEtXY24S # Wcmw4PkQ+HrLX7wbSU7QLyTZjvCQLFZ3Sb0uTf2zwsJZyeCCiT2lqAaogoMm6Kg0 # m/jG1JzE+9AC3j0Upp1lS3EK1qdxIuLdBuIcaEBEjy7Am+Y14PlZYoU2c751KbRF # kqnIOYMoijX0PJDomPqCQtYNE0mrtogo0AbcFFIu+4k25vGbkl7xS5p2du9qw2Rd # ++IdqQYzdzrUcIwmxocFQqFBJQ2dcbOGB1d7+VJ+A1Uj3yY2/DnFG5WqSaqS0KJi # ZhBdFs3OTlPnRoM= # =Dg79 # -----END PGP SIGNATURE----- # gpg: Signature made Tue 07 Nov 2023 17:13:21 HKT # gpg: using RSA key BE07D9FD54809AB2C4B0FF5F63762CDA67E2F359 # gpg: issuer "dwmw2@infradead.org" # gpg: Good signature from "David Woodhouse <dwmw2@infradead.org>" [unknown] # gpg: aka "David Woodhouse <dwmw2@exim.org>" [unknown] # gpg: aka "David Woodhouse <david@woodhou.se>" [unknown] # gpg: aka "David Woodhouse <dwmw2@kernel.org>" [unknown] # gpg: WARNING: The key's User ID is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: BE07 D9FD 5480 9AB2 C4B0 FF5F 6376 2CDA 67E2 F359 * tag 'pull-xenfv.for-upstream-20231107' of git://git.infradead.org/users/dwmw2/qemu: docs: update Xen-on-KVM documentation xen-platform: unplug AHCI disks hw/i386/pc: support '-nic' for xen-net-device hw/xen: update Xen PV NIC to XenDevice model hw/xen: only remove peers of PCI NICs on unplug hw/xen: add support for Xen primary console in emulated mode hw/xen: update Xen console to XenDevice model hw/xen: do not repeatedly try to create a failing backend device hw/xen: add get_frontend_path() method to XenDeviceClass hw/xen: automatically assign device index to block devices hw/xen: populate store frontend nodes with XenStore PFN/port i386/xen: advertise XEN_HVM_CPUID_UPCALL_VECTOR in CPUID include: update Xen public headers to Xen 4.17.2 release hw/xen: Clean up event channel 'type_val' handling to use union i386/xen: Ignore VCPU_SSHOTTMR_future flag in set_singleshot_timer() Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2023-11-07ui/console: allow to override the default VCMarc-André Lureau
If a display is backed by a specialized VC, allow to override the default "vc:80Cx24C". As suggested by Paolo, if the display doesn't implement a VC (get_vc() returns NULL), use a fallback that will use a muxed console on stdio. This changes the behaviour of "qemu -display none", to create a muxed serial/monitor by default (on TTY & not daemonized).
