| | * | YT-28305: Fix UAF in TAtomicPtr hazard-pointer publish for virtually-derived ↵babenko2026-05-275-77/+229
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | types For types that inherit TRefCountedBase virtually the original GetBasePtr implicitly converted T* to TRefCountedBase*, which requires reading the vptr of |*ptr| to find the vbase offset. The hazard protocol calls this with a ptr that another thread may have already retired, so the dereference was a heap-use-after-free. Fix: TAtomicPtr now stores the typed pointer packed with the vbase offset (TPackedPtr / TTaggedPtr). The offset is computed once at Store time, when the caller still owns a strong reference and the vbase lookup is safe. Readers and the Drop path compute the canonical TRefCountedBase* address as |ptr + offset| without ever dereferencing |*ptr|. THazardPtr::Acquire's T* overload is constrained to reject types that virtually inherit TRefCountedBase; such types must go through TAtomicPtr. Adds a ASan regression test that triggered heap-use-after-free reliably on the buggy code with barrier-synchronised reader/writer threads. commit_hash:0f15888a6224c9fbcf810d9093d82e3265a7210e

The per-call double-checked-locking pointer load on every `TCallback::Run` goes away; access is now a plain address. - `TPropagatingStorageManager::SwitchPropagatingStorage` stays out-of-line in the cpp to avoid bloating every `TCallback::Run` instantiation. - `TPropagatingStorageGuard`'s ctor and dtor move from the cpp into the inl, so the install/restore call site goes directly to `PropagatingStorageManager.SwitchPropagatingStorage(...)` without the trunk's `TPropagatingStorageManager::Get()->...` member-pointer indirection. ### FLS pointer caching - `TPropagatingStorageGuard` gains a `TFls*` cache populated on its first `SwitchPropagatingStorage` call and reused on its second. Drops one `Y_NO_INLINE` `GetCurrentFls()` call per `Run`. - Inside `SwitchPropagatingStorage`, the `TFls*&` parameter is hoisted once into a local register at function entry so subsequent in-function uses don't go through the reference. ### Storage internals - `TPropagatingStorage::Impl_` moves from `TIntrusivePtr<TImpl>` (private nested) to `TIntrusivePtr<TPropagatingStorageImpl>` (`NDetail`, defined in `propagating_storage-inl.h`). This lets the read paths — `IsNull`, `IsEmpty`, `FindRaw`, and the templated `Find` / `Has` — all inline at callers. Mutating ops (`ExchangeRaw`/`RemoveRaw`/`Clone`) stay out-of-line. - `IsNull`, `IsEmpty`, `FindRaw`, `CurrentPropagatingStorage`, and `GetCurrentPropagatingStorage` move from cpp out-of-line definitions to inl inline definitions accordingly. - `TPropagatingStorage`'s explicit special-member declarations are dropped (relying on implicit generation), except for the default ctor (`= default`) which has to stay declared because the private converting ctor would otherwise suppress it. - `TPropagatingStorageImpl`'s copy ctor is hand-written (members init explicitly) because `TRefCounted`'s copy ctor is deleted; it preserves trunk's behavior that `Clone()` carries the signal subscriber lists alongside the data map. ### Trace-context lookup - `TryGetTraceContextFromPropagatingStorage` is now defined inline in `trace_context-inl.h` (one definition; the previous `Fast` variant is merged in). Hot-path callers — `OnPropagatingStorageAfterSwitch` and the `YT_ASSERT` in `OnPropagatingStorageBeforeSwitch` — inline the lookup. An out-of-line copy is force-emitted via `[[gnu::used]]` so the GDB fiber printer (`devtools/gdb/yt_fibers_printer.py`) can still resolve the symbol at runtime. ### Inlining nudges - `TPropagateMixin::MakePropagatingStorageGuard` gains `Y_FORCE_INLINE` so it actually inlines into `TBindState::Run` rather than being emitted as a separate weak symbol per instantiation. - `TPropagatingStorage::IsNull` is also marked `[[gnu::used]]` for the same GDB-symbol-resolution reason as `TryGetTraceContextFromPropagatingStorage`. commit_hash:86793cebfc5ff891affab25dcc67d987e553854c

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## **AFL\+\+ integration into the fuzzing toolchain (replacing vanilla AFL)** **Problem being solved:** compile fuzzing targets with the `--afl` flag, substituting the clang/clang\+\+ compiler with afl-clang-fast / afl-clang-fast\+\+. The current vanilla AFL implementation is unmaintained and broken. The details were discussed here: <https://nda.ya.ru/t/lrUJhJBJ7dSnUG>. In this PR, the vanilla AFL code has been removed, leaving only `aflpp_driver.cpp` (from the AFLplusplus repository), the code that helps convert libfuzzer-like fuzzing harnesses to afl\+\+. Compilation uses the afl\+\+ toolchain, which was added in advance to `build/external_resources/aflplusplus/`. I had to make changes to the `devtools/ya` code, since I couldn't find any similar cases (selecting several compilers for a single platform depending on a flag). I chose not to register a new compiler, because afl-clang-fast is essentially a wrapper over clang with added passes — so I decided to select the compiler based on the `--afl` flag. commit_hash:cc138ebf17f07122cbcfdc9a79b371f6b73cd5ca
