* absl: fix use-after-free in Mutex/CondVarGravatar Abseil Team2022-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both Mutex and CondVar signal PerThreadSem/Waiter after satisfying the wait condition, as the result the waiting thread may return w/o waiting on the PerThreadSem/Waiter at all. If the waiting thread then exits, it currently destroys Waiter object. As the result Waiter::Post can be called on already destroyed object. PerThreadSem/Waiter must be type-stable after creation and must not be destroyed. The futex-based implementation is the only one that is not affected by the bug since there is effectively nothing to destroy (maybe only UBSan/ASan could complain about calling methods on a destroyed object). Here is the problematic sequence of events: 1: void Mutex::Block(PerThreadSynch *s) { 2: while (s->state.load(std::memory_order_acquire) == PerThreadSynch::kQueued) { 3: if (!DecrementSynchSem(this, s, s->waitp->timeout)) { 4: PerThreadSynch *Mutex::Wakeup(PerThreadSynch *w) { 5: ... 6: w->state.store(PerThreadSynch::kAvailable, std::memory_order_release); 7: IncrementSynchSem(this, w); 8: ... 9: } Consider line 6 is executed, then line 2 observes kAvailable and line 3 is not called. The thread executing Mutex::Block returns from the method, acquires the mutex, releases the mutex, exits and destroys PerThreadSem/Waiter. Now Mutex::Wakeup resumes and executes line 7 on the destroyed object. Boom! CondVar uses a similar pattern. Moreover the semaphore-based Waiter implementation is not even destruction-safe (the Waiter cannot be used to signal own destruction). So even if Mutex/CondVar would always pair Waiter::Post with Waiter::Wait before destroying PerThreadSem/Waiter, it would still be subject to use-after-free bug on the semaphore.

The old analysis viewed it as birthday attack, which asks how often there are multiple values in the probe same probe sequence with the same H2. In their own words, this analysis "breaks down" at around `n = 12`. Instead we can answer a simpler question, which is, if a probe sequence examines `k` objects that are not what we are looking for, what's the number of calls `==`? The expectation is simply `k/128`.

Unfortunately, the --cpu values are not standardized, and both --cpu=wasm and --cpu=wasm32 are used in the wild. Most notably, Emscripten's Bazel rules use --cpu=wasm, which was missing. While there, add support for @platforms//cpu:{wasm32,wasm64}.

* Exclude unsupported x64 intrinsics from ARM64EC (#1135)Gravatar Ben Niu2022-03-18
| | | | | | | | | ARM64EC is a Microsoft-designed ARM64 ABI compatible with AMD64 applications on ARM64 Windows 11. The ARM64EC does not support _umul128 and __rdtsc as x64 intrinsics, though it provides inline function implementations for them, by emulation. Since the code already has portable code paths without using the intrinsics, instead of using the emulated intrinsic implementations, we use the said portable code paths for ARM64EC.
