2023-06-02migration: restore vmstate on migration failureVladimir Sementsov-Ogievskiy1-1/+7
1. Otherwise failed migration just drops guest-panicked state, which is not good for management software. 2. We do keep different paused states like guest-panicked during migration with help of global_state state. 3. We do restore running state on source when migration is cancelled or failed. 4. "postmigrate" state is documented as "guest is paused following a successful 'migrate'", so originally it's only for successful path and we never documented current behavior. Let's restore paused states like guest-panicked in case of cancel or fail too. Allow same transitions like for inmigrate state. This commit changes the behavior that was introduced by commit 42da5550d6 "migration: set state to post-migrate on failure" and provides a bit different fix on related https://bugzilla.redhat.com/show_bug.cgi?id=1355683 Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@yandex-team.ru> Reviewed-by: Juan Quintela <quintela@redhat.com> Message-Id: <20230517123752.21615-6-vsementsov@yandex-team.ru> Signed-off-by: Juan Quintela <quintela@redhat.com>

2023-05-25softmmu/ioport.c: make MemoryRegionPortioList owner of portio_list MemoryRegionsMark Cave-Ayland1-1/+21
Currently when portio_list MemoryRegions are freed using portio_list_destroy() the RCU thread segfaults generating a backtrace similar to that below: #0 0x5555599a34b6 in phys_section_destroy ../softmmu/physmem.c:996 #1 0x5555599a37a3 in phys_sections_free ../softmmu/physmem.c:1011 #2 0x5555599b24aa in address_space_dispatch_free ../softmmu/physmem.c:2430 #3 0x55555996a283 in flatview_destroy ../softmmu/memory.c:292 #4 0x55555a2cb9fb in call_rcu_thread ../util/rcu.c:284 #5 0x55555a29b71d in qemu_thread_start ../util/qemu-thread-posix.c:541 #6 0x7ffff4a0cea6 in start_thread nptl/pthread_create.c:477 #7 0x7ffff492ca2e in __clone (/lib/x86_64-linux-gnu/libc.so.6+0xfca2e) The problem here is that portio_list_destroy() unparents the portio_list MemoryRegions causing them to be freed immediately, however the flatview still has a reference to the MemoryRegion and so causes a use-after-free segfault when the RCU thread next updates the flatview. Solve the lifetime issue by making MemoryRegionPortioList the owner of the portio_list MemoryRegions, and then reparenting them to the portio_list owner. This ensures that they can be accessed as QOM children via the portio_list owner, yet the MemoryRegionPortioList owns the refcount. Update portio_list_destroy() to unparent the MemoryRegion from the portio_list owner (while keeping mrpio->mr live until finalization of the MemoryRegionPortioList), so that the portio_list MemoryRegions remain allocated until flatview_destroy() removes the final refcount upon the next flatview update.

2023-05-25softmmu/ioport.c: QOMify MemoryRegionPortioListMark Cave-Ayland1-5/+31
The aim of QOMification is so that the lifetime of the MemoryRegionPortioList structure can be managed using QOM's in-built refcounting instead of having to handle this manually. Due to the use of an opaque pointer it isn't possible to model the new TYPE_MEMORY_REGION_PORTIO_LIST directly using QOM properties, however since use of the new object is restricted to the portio API we can simply set the opaque pointer (and the heap-allocated port list) internally.

2023-05-18migration: Add last stage indicator to global dirty logGavin Shan1-5/+5
The global dirty log synchronization is used when KVM and dirty ring are enabled. There is a particularity for ARM64 where the backup bitmap is used to track dirty pages in non-running-vcpu situations. It means the dirty ring works with the combination of ring buffer and backup bitmap. The dirty bits in the backup bitmap needs to collected in the last stage of live migration. In order to identify the last stage of live migration and pass it down, an extra parameter is added to the relevant functions and callbacks. This last stage indicator isn't used until the dirty ring is enabled in the subsequent patches. No functional change intended.

2023-05-02hmp: Add 'one-insn-per-tb' command equivalent to 'singlestep'Peter Maydell1-1/+1
The 'singlestep' HMP command is confusing, because it doesn't actually have anything to do with single-stepping the CPU. What it does do is force TCG emulation to put one guest instruction in each TB, which can be useful in some situations. Create a new HMP command 'one-insn-per-tb', so we can document that 'singlestep' is just a deprecated synonym for it, and eventually perhaps drop it. We aren't obliged to do deprecate-and-drop for HMP commands, but it's easy enough to do so, so we do.

2023-05-02accel/tcg: Use one_insn_per_tb global instead of old singlestep globalPeter Maydell1-1/+0
The only place left that looks at the old 'singlestep' global variable is the TCG curr_cflags() function. Replace the old global with a new 'one_insn_per_tb' which is defined in tcg-all.c and declared in accel/tcg/internal.h. This keeps it restricted to the TCG code, unlike 'singlestep' which was available to every file in the system and defined in multiple different places for softmmu vs linux-user vs bsd-user. While we're making this change, use qatomic_read() and qatomic_set() on the accesses to the new global, because TCG will read it without holding a lock.

This commit adds 'one-insn-per-tb' as a property on the TCG accelerator object, so you can enable it with -accel tcg,one-insn-per-tb=on It has the same behaviour as the existing '-singlestep' command line option. We use a different name because 'singlestep' has always been a confusing choice, because it doesn't have anything to do with single-stepping the CPU. What it does do is force TCG emulation to put one guest instruction in each TB, which can be useful in some situations (such as analysing debug logs). The existing '-singlestep' commandline options are decoupled from the global 'singlestep' variable and instead now are syntactic sugar for setting the accel property. (These can then go away after a deprecation period.) The global variable remains for the moment as: * what the TCG code looks at to change its behaviour * what HMP and QMP use to query and set the behaviour In the following commits we'll clean those up to not directly look at the global variable.

2023-04-28memory: prevent dma-reentracy issuesAlexander Bulekov1-0/+16
Add a flag to the DeviceState, when a device is engaged in PIO/MMIO/DMA. This flag is set/checked prior to calling a device's MemoryRegion handlers, and set when device code initiates DMA. The purpose of this flag is to prevent two types of DMA-based reentrancy issues: 1.) mmio -> dma -> mmio case 2.) bh -> dma write -> mmio case These issues have led to problems such as stack-exhaustion and use-after-frees.

When building it with other ones (or without TCG) we get: softmmu/watchpoint.c:38:9: error: implicit declaration of function 'error_report' is invalid in C99 [-Werror,-Wimplicit-function-declaration] error_report("tried to set invalid watchpoint at %" ^ Include "qemu/error-report.h" in order to fix this for non-TCG builds.

Commit 85c4bf8aa6 ("vl: Unlink absolute PID file path") introduced a critical error when the PID file path cannot be resolved. Before this commit, it was possible to invoke QEMU when the PID file was a file created with mkstemp that was already unlinked at the time of the invocation. There might be other similar scenarios. It should not be a critical error when the PID file unlink notifier can't be registered, because the path can't be resolved. If the file is already gone from QEMU's perspective, silently ignore the error. Otherwise, only print a warning.

Our GDB syscall support is the last chunk of code that needs target specific support so move it to a new file. We take the opportunity to move the syscall state into its own singleton instance and add in a few helpers for the main gdbstub to interact with the module. I also moved the gdb_exit() declaration into syscalls.h as it feels pretty related and most of the callers of it treat it as such.

2023-03-07hw/xen: Add gnttab operations to allow redirection to internal emulationDavid Woodhouse1-0/+1
Move the existing code using libxengnttab to xen-operations.c and allow the operations to be redirected so that we can add emulation of grant table mapping for backend drivers. In emulation, mapping more than one grant ref to be virtually contiguous would be fairly difficult. The best way to do it might be to make the ram_block mappings actually backed by a file (shmem or a deleted file, perhaps) so that we can have multiple *shared* mappings of it. But that would be fairly intrusive. Making the backend drivers cope with page *lists* instead of expecting the mapping to be contiguous is also non-trivial, since some structures would actually *cross* page boundaries (e.g. the 32-bit blkif responses which are 12 bytes). So for now, we'll support only single-page mappings in emulation. Add a XEN_GNTTAB_OP_FEATURE_MAP_MULTIPLE flag to indicate that the native Xen implementation *does* support multi-page maps, and a helper function to query it.
