…otnet#7732) Fixes: dotnet#7335 Context: d236af5 Commit d236af5 introduced embedded assembly compression, using LZ4, which speeds up startup and reduces final package size. Assemblies are compressed at build time and, at the same time, pre- allocated buffers for the **decompressed** data are allocated in `libxamarin-app.so`. The buffers are then passed to the LZ4 APIs, all threads using the same output buffer. The assumption was that we can do fine without locking as even if overlapped decompression happens, the output data will be the same and so even if two threads do the same thing at the same time, the data will be valid at all times, so long as at least one thread completes the decompression. This assumption proved to be **largely** true, but it appears that in high concurrency cases it is possible that the data in the decompression buffer differs. This can result in app crashes: A/libc: Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 3092 (.NET ThreadPool), pid 2727 (myapp.name) A/DEBUG: pid: 2727, tid: 3092, name: .NET ThreadPool >>> myapp.name <<< A/DEBUG: #1 pc 0000000000029b1c /data/app/myapp.name-B9t_3dF9i8mDxJEKodZw5w==/split_config.arm64_v8a.apk!libmono-android.release.so (offset 0x103d000) (xamarin::android::internal::MonodroidRuntime::mono_log_handler(char const*, char const*, char const*, int, void*)+144) (BuildId: 29c5a3805a0bedee1eede9b6668d7c676aa63371) A/DEBUG: #2 pc 00000000002680bc /data/app/myapp.name-B9t_3dF9i8mDxJEKodZw5w==/split_config.arm64_v8a.apk!libmonosgen-2.0.so (offset 0x109b000) (BuildId: 4a5dd4396e8816b7f69881838bd549285213d53b) A/DEBUG: #3 pc 00000000002681e8 /data/app/myapp.name-B9t_3dF9i8mDxJEKodZw5w==/split_config.arm64_v8a.apk!libmonosgen-2.0.so (offset 0x109b000) (BuildId: 4a5dd4396e8816b7f69881838bd549285213d53b) A/DEBUG: #4 pc 000000000008555c /data/app/myapp.name-B9t_3dF9i8mDxJEKodZw5w==/split_config.arm64_v8a.apk!libmonosgen-2.0.so (offset 0x109b000) (mono_metadata_string_heap+188) (BuildId: 4a5dd4396e8816b7f69881838bd549285213d53b) … My guess is that LZ4 either uses the output buffer as a scratchpad area when decompressing or that it initializes/modifies the buffer before writing actual data in it. With overlapped decompression, it may lead to one thread overwriting valid data previously written by another thread, so that when the latter returns the buffer it thought to have had valid data may contain certain bytes temporarily overwritten by the decompression session in the other, still running, thread. It may happen that MonoVM reads the corrupted data just when it is still invalid (before the still running decompression session actually writes the valid data), a classic race condition. To fix this, the decompression block is now protected with a startup- aware mutex. Mutex will be held only after the initial startup phase is completed, so there should not be much loss of startup performance.

) Context: 929e701 Context: ce2bc68 Context: dotnet#7473 Context: dotnet#8155 The managed linker can produce assemblies optimized for the target `$(RuntimeIdentifier)` (RID), which means that they will differ between different RIDs. Our "favorite" example of this is `IntPtr.Size`, which is inlined by the linker into `4` or `8` when targeting 32-bit or 64-bit platforms. (See also dotnet#7473 and 929e701.) Another platform difference may come in the shape of CPU intrinsics which will change the JIT-generated native code in ways that will crash the application if the assembler instructions generated for the intrinsics aren't supported by the underlying processor. In addition, the per-RID assemblies will have different [MVID][0]s and **may** have different type and method metadata token IDs, which is important because typemaps *use* type and metadata token IDs; see also ce2bc68. All of this taken together invalidates our previous assumption that all the managed assemblies are identical. "Simply" using `IntPtr.Size` in an assembly that contains `Java.Lang.Object` subclasses will break things. This in turn could cause "mysterious" behavior or crashes in Release applications; see also Issue dotnet#8155. Prevent the potential problems by processing each per-RID assembly separately and output correct per-RID LLVM IR assembly using the appropriate per-RID information. Additionally, during testing I found that for our use of Cecil within `<GenerateJavaStubs/>` doesn't consistently remove the fields, delegates, and methods we remove in `MarshalMethodsAssemblyRewriter` when marshal methods are enabled, or it generates subtly broken assemblies which cause **some** applications to segfault at run time like so: I monodroid-gc: 1 outstanding GREFs.

At this point, we have the results returned by the subclass scanner in memory and **new** versions of those types on disk, but they are out of sync, since the types in memory refer to the **old** assemblies, but AOT is ran on the **new** assemblies which have a different layout, changed MVIDs and, potentially, different type and method token IDs (because we added some methods, removed others etc) and thus it causes the crashes at the run time. The now invalid set of "old" types is passed to the typemap generator. This only worked by accident, because we (incorrectly) used only the first linked assembly which happened to be the same one passed to the JLO scanner and AOT - so everything was fine at the execution time. Address this by *disabling* LLVM Marshal Methods (8bc7a3e) for .NET 8, setting `$(AndroidEnableMarshalMethods)`=False by default. We'll attempt to fix these issues for .NET 9.

The problem is that `/` *wasn't* consistently used to build the compile-time hash values; `MarshalMethodsNativeAssemblyGenerator.AddAssemblyImageCache()` used `Path.Combine()`, which would use `\` on Windows, not `/`. The result is that if the app was built on Windows, the compile-time data would hash e.g. `pt\Testnet9.dll`, which would be a different hash value than that produced by `pt/Testnet9.dll`. This in turn would result in a "lookup miss": F monodroid-assembly: Failed to look up image index for hash 0x7357acbda27bdba3 followed by an abort. Fix this by updating `AddAssemblyImageCache()` to normalize on `/`. [0]: https://learn.microsoft.com/dotnet/maui/fundamentals/localization?view=net-maui-8.0

TL;DR dotnet/android already runs majority of its threads as cooperate suspend aware threads (GC safe when return from thread attach) and hybrid suspend will pre-emptive suspend threads that are currently in GC safe mode, indicates that changing the remaining calls from `mono_thread_attach` into `mono_jit_thread_attach` should be a low-risk change. The full story: Mono runtime can run in different suspend models, pre-emptive, hybrid or coop suspend. In the past, Xamarin Android (mono/mono), used pre-emptive suspend model, but starting with .net6, dotnet Android switched to hybrid suspend model. The major difference between these two is how threads are suspend/resumed when triggering a GC, pre-emptive suspend relies on signals, meaning that any thread attached to the runtime, can be suspended at any location in code, including in bad areas that could cause side effects (like holding low level locks). The Mono embedding API's was original designed with this suspend model in mind. The hybrid suspend model on the other hand is a combination between pre-emptive and cooperate suspend model, but for this discussion, the interesting part is the fact that threads running GC unsafe under hybrid suspend need to hit safe points to be suspended, if not hitting a safe point, the runtime will (by default), wait for that thread forever, hanging the GC in its stw "stop the world" phase. A safe point is a location in code where thread will yield execution and wait for GC to complete and resume it. A safe point is just a location where a thread tells the runtime that it's in a GC safe region promising not to touch any managed memory or call any runtime functions as described here, https://www.mono-project.com/docs/advanced/runtime/docs/coop-suspend/#gc-safe-mode. The switching back and forth between GC unsafe and safe is mainly taken care of by the runtime, for example, calling a p/invoke will mark the thread as being in GC safe mode while running the p/invoke, internal runtime waits, hitting safe points in C# code etc. A thread running in GC unsafe mode means that its executing managed or runtime code and needs to hit a safe point before it can be suspended by GC. A thread could start out either as in GC unsafe or safe mode. The following lists a couple of scenarios: * `mono_thread_attach` due to backward compability with Mono embedding API and embedders, thread attached to the runtime in GC unsafe mode, meaning that it needs to reach a safe point to be suspended. * `mono_jit_thread_attach` thread gets attached to the runtime in GC safe mode. * `mono_jit_init`/`mono_jit_init_version`, thread calling these functions to initialize the runtime will be put in GC safe mode. * Native to managed wrappers, like unmanaged callers only methods, reverse p/invoke function pointers, `GetFunctionPointerForDelegate` etc, will attach unattached threads so they will be in GC safe mode on return. A thread that is running in GC safe mode must be switched to GC unsafe mode when re-entering managed or runtime code. When calling through the native to managed wrappers, this will be taken care of by the wrapper. When calling through the Mono embedding API's, each individual API needs to take a decision (based on what it does) to switch to GC unsafe and then back to the state thread had when entering the API (could actually be GC unsafe if it was called in GC unsafe mode). Threads GC mode is critical when running a GC, since GC would need to do a stw in order to proceed with GC work. The hybrid suspend models stw is a little more complex in how it operates compared to both pre-emptive and coop suspend, but it mainly boils down to two steps. The first, all threads attached to the runtime will be checked. If thread is currently in GC safe mode, it will be ignored in first step, all threads in GC unsafe mode will be waited upon until they reach a safe point. This is normally where we see deadlocks in ANR's due to threads not reaching safe points in timely manners. Once the first phase is done (all threads in GC unsafe mode reached safe points), second phase will consider all threads still in GC safe mode and pre-emptive suspended them (using signals). We have identified several ANR's (Application Not Responding) on Android where we seen threads attached to runtime with callstacks like this: ``` "queue-1-2" tid=8105 Native #00 pc 0x000000000006a0c0 /system/lib64/libc.so (__rt_sigsuspend+4) #1 pc 0x0000000000029684 /system/lib64/libc.so (sigsuspend+44) #2 pc 0x00000000001ff994 /data/app/<app.bundle.id>-_I4CSOAWam382fA8t14IEg==/lib/arm64/libmonosgen-2.0.so (suspend_signal_handler+200) #3 pc 0x00000000000005dc [vdso:000000737837f000] #4 pc 0x000000000001dae8 /system/lib64/libc.so (syscall+24) #5 pc 0x00000000000e1ee4 /system/lib64/libart.so (art::ConditionVariable::WaitHoldingLocks(art::Thread*)+152) #6 pc 0x0000000000392794 /system/lib64/libart.so (art::Monitor::Wait(art::Thread*, long, int, bool, art::ThreadState)+632) #7 pc 0x0000000000394288 /system/lib64/libart.so (art::Monitor::Wait(art::Thread*, art::mirror::Object*, long, int, bool, art::ThreadState)+252) #8 pc 0x00000000001dcadc /system/framework/arm64/boot.oat (java.lang.Object.wait [DEDUPED]+140) #9 pc 0x00000000001fcebc /system/framework/arm64/boot.oat (java.lang.Thread.parkFor$+428) #10 pc 0x0000000000608cd8 /system/framework/arm64/boot.oat (java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await+808) #11 pc 0x00000000005de8ec /system/framework/arm64/boot.oat (java.util.concurrent.LinkedBlockingQueue.take+156) #12 pc 0x00000000005e9e1c /system/framework/arm64/boot.oat (java.util.concurrent.ThreadPoolExecutor.getTask+492) #13 pc 0x00000000005ec2b0 /system/framework/arm64/boot.oat (java.util.concurrent.ThreadPoolExecutor.runWorker+240) #14 pc 0x00000000005fb114 /system/framework/arm64/boot.oat (java.util.concurrent.ThreadPoolExecutor$Worker.run+68) #15 pc 0x00000000001fd13c /system/framework/arm64/boot.oat (java.lang.Thread.run+76) #16 pc 0x0000000000509384 /system/lib64/libart.so (art_quick_invoke_stub+580) #17 pc 0x00000000000d8078 /system/lib64/libart.so (art::ArtMethod::Invoke(art::Thread*, unsigned int*, unsigned int, art::JValue*, char const*)+200) #18 pc 0x0000000000431120 /system/lib64/libart.so (art::InvokeWithArgArray(art::ScopedObjectAccessAlreadyRunnable const&, art::ArtMethod*, art::ArgArray*, art::JValue*, char const*)+104) #19 pc 0x00000000004322ac /system/lib64/libart.so (art::InvokeVirtualOrInterfaceWithJValues(art::ScopedObjectAccessAlreadyRunnable const&, _jobject*, _jmethodID*, jvalue*)+432) #20 pc 0x0000000000458e8c /system/lib64/libart.so (art::Thread::CreateCallback(void*)+1140) #21 pc 0x00000000000678b4 /system/lib64/libc.so (__pthread_start(void*)+36) #22 pc 0x000000000001ef24 /system/lib64/libc.so (__start_thread+68) ``` This thread is attached to runtime since its running our suspend signal handler, but it also seems to be waiting inside some Java thread pool. This works under pre-emptive suspend, but if the same thread has been attached to runtime under hybrid and ends up waiting like this outside of managed and runtime code, then the thread must be in GC safe mode or it will violate the runtime hybrid suspend model, since if a thread is in GC unsafe mode, then it needs to reach a safe point in timely manner, something above callstack will probably never do, blocking the completion of stw. It turns out that dotnet/android codebase still have two locations that could attach threads using `mono_thread_attach`, while the majority of threads are attached either as runtime init thread, marshalled methods using `mono_jit_thread_attach` or native to managed wrappers. Thread attached using one of the above will be in GC safe mode, meaning they should either reach safe points or being pre-emptive suspended under hybrid suspend model. After analyzing the code paths in dotnet/android ending up in calls to `mono_thread_attach` it is however still not clear if they are reachable in real world scenarios, but since we have ANR's that points to issues suspending threads, we seen threads with callstack waiting outside runtime and majority of threads attached to runtime running dotnet Android seems to attach as cooperate suspend aware (GC safe mode on return), it would make sense to standardize and attach all threads as cooperate suspend aware in dotnet/android repro. As part of this analysis, I also looked over all Mono API's used by dotnet/runtime, analyzed if they are correctly switching to GC unsafe when called, if the API's are cooperate aware and if they are safe to only be called during init or before running managed code. The fact that hybrid suspend will do a pre-emptive suspend on threads that are running in GC safe mode reduce issues using API's that currently won't enter GC unsafe (but probably should) or are not cooperate suspend aware, passing raw GC objects as parameter or return values. Since we already run majority of threads as cooperate suspend aware threads (GC safe when return from thread attach) in dotnet/android and that hybrid suspend will pre-emptive suspend threads that are currently in GC safe mode, indicates that changing the remaining calls from `mono_thread_attach` into `mono_jit_thread_attach` should be a low risk change. For completion, this is the list of Mono embedding API's used by dotnet/android and their state regarding switching to GC unsafe, being cooperate suspend aware and potential implications. API's without comments should be safe to call under any suspend model. API's marked as "init-only" should be called before runtime or before running managed code. They are either not thread safe changing runtime state or used during runtime initialization or needs to be in place before running managed code. API's marked with "Can't be called under coop suspend model." normally means that the API uses raw GC objects as parameters or return values. These API's can't be called under cooperate suspend model, but since hybrid suspend model will pre-emptive suspend threads in GC safe mode, it can still scan threads active stack and registers, so should be able to handle direct GC references on stack or in register for all attached runtime threads. The last category "Should transition to GC unsafe.", is mainly API's that should do a GC unsafe transition internally but currently don't. This is something that should probably be fixed in runtime and until done, these API's can't be safely called under coop suspend model. They should however still be safe under hybrid suspend, since threads in GC safe mode will be pre-empted. | Mono API | GC Unsafe | Cooperate | Comment | |-----------------------------------------------|-----------|-----------|----------------------------------------------| | mono_add_internal_call | No | Yes | init-only | | mono_alc_get_default_gchandle | No | Yes | | | mono_array_new | Yes | No | Can't be called under coop suspend model. | | mono_assembly_get_image | Yes | Yes | | | mono_assembly_load_from_full | Yes | Yes | | | mono_assembly_load_full | Yes | Yes | | | mono_assembly_load_full_alc | Yes | Yes | | | mono_assembly_loaded | Yes | Yes | | | mono_assembly_name_free | Yes | Yes | | | mono_assembly_name_get_culture | Yes | Yes | | | mono_assembly_name_get_name | Yes | Yes | | | mono_assembly_name_new | Yes | Yes | | | mono_assembly_open_full | Yes | Yes | | | mono_check_corlib_version | Yes | Yes | | | mono_class_from_mono_type | Yes | Yes | | | mono_class_from_name | Yes | Yes | | | mono_class_get | Yes | Yes | | | mono_class_get_field_from_name | Yes | Yes | | | mono_class_get_image | No | Yes | | | mono_class_get_method_from_name | Yes | Yes | | | mono_class_get_name | Yes | Yes | | | mono_class_get_namespace | Yes | Yes | | | mono_class_get_type | No | Yes | | | mono_class_get_type_token | No | Yes | | | mono_class_is_subclass_of | Yes | Yes | | | mono_class_vtable | Yes | Yes | | | mono_config_is_server_mode | No | Yes | | | mono_debug_init | No | Yes | init-only | | mono_debug_open_image_from_memory | Yes | Yes | | | mono_debugger_agent_unhandled_exception | Yes | No | Can't be called under coop suspend model. | | mono_dl_fallback_register | No | Yes | init-only | | mono_domain_foreach | Yes | Yes | | | mono_domain_get | No | Yes | | | mono_domain_get_id | No | Yes | | | mono_domain_set | Yes | Yes | | | mono_error_get_message | No | Yes | Should transition to GC unsafe. | | mono_field_get_value | Yes | No | Can't be called under coop suspend model. | | mono_field_set_value | Yes | No | Can't be called under coop suspend model. | | mono_field_static_set_value | Yes | Yes | | | mono_gc_register_bridge_callbacks | No | Yes | init-only | | mono_gc_wait_for_bridge_processing | Yes | Yes | | | mono_get_byte_class | No | Yes | | | mono_get_method | No | Yes | Should transition to GC unsafe. | | mono_get_root_domain | No | Yes | | | mono_get_runtime_build_info | No | Yes | | | mono_guid_to_string | No | Yes | | | mono_image_get_name | No | Yes | | | mono_image_loaded | Yes | Yes | | | mono_image_open_from_data_alc | Yes | Yes | | | mono_image_open_from_data_with_name | Yes | Yes | | | mono_image_strerror | No | Yes | | | mono_install_assembly_preload_hook | No | Yes | init-only | | mono_install_assembly_preload_hook_v3 | No | Yes | init-only | | mono_jit_init_version | No | Yes | | | mono_jit_parse_options | No | Yes | init-only | | mono_jit_set_aot_mode | No | Yes | init-only | | mono_jit_set_trace_options | No | Yes | init-only | | mono_jit_thread_attach | No | Yes | | | mono_method_full_name | Yes | Yes | | | mono_method_get_unmanaged_callers_only_ftnptr | Yes | Yes | | | mono_object_get_class | Yes | No | Can't be called under coop suspend model. | | mono_profiler_create | No | Yes | init-only | | mono_reflection_assembly_get_assembly | No | No | Can't be called under coop suspend model. | | mono_reflection_type_from_name | Yes | Yes | | | mono_reflection_type_get_type | Yes | No | Can't be called under coop suspend model. | | mono_runtime_init | No | Yes | | | mono_runtime_invoke | Yes | No | Can't be called under coop suspend model. | | mono_runtime_set_main_args | No | Yes | init-only | | mono_set_crash_chaining | No | Yes | init-only | | mono_set_signal_chaining | No | Yes | init-only | | mono_set_use_llvm | No | Yes | init-only | | mono_string_chars | No | No | Can't be called under coop suspend model. | | mono_string_length | No | No | Can't be called under coop suspend model. | | mono_string_new | Yes | No | Can't be called under coop suspend model. | | mono_string_to_utf8 | Yes | No | Can't be called under coop suspend model. | | mono_thread_attach | No | No | Can't be called under coop suspend model. | | mono_thread_create | Yes | Yes | | | mono_trace_set_level_string | No | Yes | init-only | | mono_trace_set_log_handler | No | Yes | init-only | | mono_trace_set_mask_string | No | Yes | init-only | | mono_trace_set_print_handler | No | Yes | init-only | | mono_trace_set_printerr_handler | No | Yes | init-only | | mono_type_get_name_full | No | Yes | Should transition to GC unsafe. | | mono_type_get_object | Yes | No | Can't be called under coop suspend model. | | mono_unhandled_exception | Yes | No | Can't be called under coop suspend model. | | mono_value_copy_array | No | No | Can't be called under coop suspend model. |
