2024-03-12hw/virtio: check owner for removing objectsAlbert Esteve
Shared objects lack spoofing protection. For VHOST_USER_BACKEND_SHARED_OBJECT_REMOVE messages received by the vhost-user interface, any backend was allowed to remove entries from the shared table just by knowing the UUID. Only the owner of the entry shall be allowed to removed their resources from the table. To fix that, add a check for all *SHARED_OBJECT_REMOVE messages received. A vhost device can only remove TYPE_VHOST_DEV entries that are owned by them, otherwise skip the removal, and inform the device that the entry has not been removed in the answer.

2024-03-11migration/multifd: Don't fsync when closing QIOChannelFileFabiano Rosas
Commit bc38feddeb ("io: fsync before closing a file channel") added a fsync/fdatasync at the closing point of the QIOChannelFile to ensure integrity of the migration stream in case of QEMU crash. The decision to do the sync at qio_channel_close() was not the best since that function runs in the main thread and the fsync can cause QEMU to hang for several minutes, depending on the migration size and disk speed. To fix the hang, remove the fsync from qio_channel_file_close(). At this moment, the migration code is the only user of the fsync and we're taking the tradeoff of not having a sync at all, leaving the responsibility to the upper layers.

2024-03-11hw/arm: Deprecate various old Arm machine typesPeter Maydell
QEMU includes some models of old Arm machine types which are a bit problematic for us because: * they're written in a very old way that uses numerous APIs that we would like to get away from (eg they don't use qdev, they use qemu_system_reset_request(), they use vmstate_register(), etc) * they've been that way for a decade plus and nobody particularly has stepped up to try to modernise the code (beyond some occasional work here and there) * we often don't have test cases for them, which means that if we do try to do the necessary refactoring work on them we have no idea if they even still work at all afterwards All these machine types are also of hardware that has largely passed away into history and where I would not be surprised to find that e.g. the Linux kernel support was never tested on real hardware any more. After some consultation with the Linux kernel developers, we are going to deprecate: All PXA2xx machines: akita Sharp SL-C1000 (Akita) PDA (PXA270) borzoi Sharp SL-C3100 (Borzoi) PDA (PXA270) connex Gumstix Connex (PXA255) mainstone Mainstone II (PXA27x) spitz Sharp SL-C3000 (Spitz) PDA (PXA270) terrier Sharp SL-C3200 (Terrier) PDA (PXA270) tosa Sharp SL-6000 (Tosa) PDA (PXA255) verdex Gumstix Verdex Pro XL6P COMs (PXA270) z2 Zipit Z2 (PXA27x) All OMAP2 machines: n800 Nokia N800 tablet aka. RX-34 (OMAP2420) n810 Nokia N810 tablet aka. RX-44 (OMAP2420) One of the OMAP1 machines: cheetah Palm Tungsten|E aka. Cheetah PDA (OMAP310) Rationale: * for QEMU dropping individual machines is much less beneficial than if we can drop support for an entire SoC * the OMAP2 QEMU code in particular is large, old and unmaintained, and none of the OMAP2 kernel maintainers said they were using QEMU in any of their testing/development * although there is a setup that is booting test kernels on some of the PXA2xx machines, nobody seemed to be using them as part of their active kernel development and my impression from the email thread is that PXA is the closest of all these SoC families to being dropped from the kernel soon * nobody said they were using cheetah, so it's entirely untested and quite probably broken * on the other hand the OMAP1 sx1 model does seem to be being used as part of kernel development, and there was interest in keeping collie around In particular, the mainstone, tosa and z2 machine types have already been dropped from Linux. Mark all these machine types as deprecated.

Currently, it was allowed for users to specify the unsupported topology parameter as "1". For example, x86 PC machine doesn't support drawer/book/cluster topology levels, but user could specify "-smp drawers=1,books=1,clusters=1". This is meaningless and confusing, so that the support for this kind of configurations is marked deprecated since 9.0. And report warning message for such case like: qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid): Unsupported clusters parameter mustn't be specified as 1 qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid): Unsupported books parameter mustn't be specified as 1 qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid): Unsupported drawers parameter mustn't be specified as 1 Users have to ensure that all the topology members described with -smp are supported by the target machine.

2024-03-04docs/conf.py: Remove usage of distutilsThomas Huth
The macOS jobs in our CI recently started failing, complaining that the distutils module is not available anymore. And indeed, according to https://peps.python.org/pep-0632/ it's been deprecated since a while and now likely got removed in recent Python versions. Fortunately, we only use it for a version check via LooseVersion here which we don't really need anymore - according to Repology.org, these are the versions of sphinx-rtd-theme that are currently used by the various distros: centos_stream_8: 0.3.1 centos_stream_9: 0.5.1 fedora_38: 1.1.1 fedora_39: 1.2.2 freebsd: 1.0.0 haikuports_master: 1.2.1 openbsd: 1.2.2 opensuse_leap_15_5: 0.5.1 pkgsrc_current: 2.0.0 debian_11: 0.5.1 debian_12: 1.2.0 ubuntu_20_04: 0.4.3 ubuntu_22_04: 1.0.0 ubuntu_24_04: 2.0.0 So except for CentOS 8, all distros are using a newer version of sphinx-rtd-theme, and for CentOS 8 we don't support compiling with the Sphinx of the distro anymore anyway, since it's based on the Python 3.6 interpreter there. For compiling on CentOS 8, you have to use the alternative Python 3.8 interpreter which comes without Sphinx, so that needs the Sphinx installed via pip in the venv instead, and that is using a newer version, too, according to our pythondeps.toml file. Thus we can simply drop the version check now to get rid of the distutils dependency here.

2024-03-04docs/devel/writing-monitor-commands: Repair a decade of rotMarkus Armbruster
The tutorial doesn't match reality since at least 2013. Repairing it involves fixing the following issues: * Update for commit 6d327171551 (aio / timers: Remove alarm timers): replace the broken examples. Instead of having one for returning a struct and another for returning a list of structs, do just one for the latter. This resolves the FIXME added in commit e218052f928 (aio / timers: De-document -clock) back in 2014. * Update for commit 895a2a80e0e (qapi: Use 'struct' instead of 'type' in schema). * Update for commit 3313b6124b5 (qapi: add qapi2texi script): add required documentation to the schema snippets, and drop section "Command Documentation". * Update for commit a3c45b3e629 (qapi: New special feature flag "unstable"): supply the required feature, deemphasize the x- prefix. * Update for commit dd98234c059 (qapi: introduce x-query-roms QMP command): rephrase from "add new command" to "examine existing command". * Update for commit 9492718b7c0 (qapi misc: Elide redundant has_FOO in generated C): hello-world's message argument no longer comes with a has_message, add a second argument that does. * Update for moved and renamed files.

2024-03-01migration/ram: Introduce 'mapped-ram' migration capabilityFabiano Rosas
Add a new migration capability 'mapped-ram'. The core of the feature is to ensure that RAM pages are mapped directly to offsets in the resulting migration file instead of being streamed at arbitrary points. The reasons why we'd want such behavior are: - The resulting file will have a bounded size, since pages which are dirtied multiple times will always go to a fixed location in the file, rather than constantly being added to a sequential stream. This eliminates cases where a VM with, say, 1G of RAM can result in a migration file that's 10s of GBs, provided that the workload constantly redirties memory. - It paves the way to implement O_DIRECT-enabled save/restore of the migration stream as the pages are ensured to be written at aligned offsets. - It allows the usage of multifd so we can write RAM pages to the migration file in parallel. For now, enabling the capability has no effect. The next couple of patches implement the core functionality.

2024-02-29*-user: Deprecate and disable -p pagesizeRichard Henderson
This option controls the host page size. From the mis-usage in our own testsuite, this is easily confused with guest page size. The only thing that occurs when changing the host page size is that stuff breaks, because one cannot actually change the host page size. Therefore reject all but the no-op setting as part of the deprecation process.

2024-02-28contrib/plugins: extend execlog to track register changesAlex Bennée
With the new plugin register API we can now track changes to register values. Currently the implementation is fairly dumb which will slow down if a large number of register values are being tracked. This could be improved by only instrumenting instructions which mention registers we are interested in tracking. Example usage: ./qemu-aarch64 -D plugin.log -d plugin \ -cpu max,sve256=on \ -plugin contrib/plugins/libexeclog.so,reg=sp,reg=z\* \ ./tests/tcg/aarch64-linux-user/sha512-sve will display in the execlog any changes to the stack pointer (sp) and the SVE Z registers. As testing registers every instruction will be quite a heavy operation there is an additional flag which attempts to optimise the register tracking by only instrumenting instructions which are likely to change its value. This relies on the QEMU disassembler showing up the register names in disassembly so is an explicit opt-in.
