Max Kellermann b47bfd698d ext/opcache: C++ compatibility 
Just in case somebody includes those headers from C++ code.  The same
already exists in other opcache headers.

Max Kellermann bcc5d268f6 ext/opcache/jit/zend_jit_trace: fix memory leak in _compile_root_trace() (#10146) 
A copy of this piece of code exists in zend_jit_compile_side_trace(),
but there, the leak bug does not exist.

This bug exists since both copies of this piece of code were added in
commit 4bf2d09ede

Max Kellermann e217138b40 ext/opcache/jit/zend_jit_trace: add missing lock for EXIT_INVALIDATE 
Commit 6c25413183 added the flag ZEND_JIT_EXIT_INVALIDATE which
resets the trace handlers in zend_jit_trace_exit(), but forgot to
lock the shared memory section.

This could cause another worker process who still saw the
ZEND_JIT_TRACE_JITED flag to schedule ZEND_JIT_TRACE_STOP_LINK, but
when it arrived at the ZEND_JIT_DEBUG_TRACE_STOP, the handler was
already reverted by the first worker process and thus
zend_jit_find_trace() fails.

This in turn generated a bogus jump offset in the JITed code, crashing
the PHP process.

Max Kellermann b26b758952 ext/opcache/jit: handle zend_jit_find_trace() failures 
Commit 6c25413 added the flag ZEND_JIT_EXIT_INVALIDATE which resets
the trace handlers in zend_jit_trace_exit(), but forgot to consider
that on ZEND_JIT_TRACE_STOP_LINK, this changed handler gets passed to
zend_jit_find_trace(), causing it to fail, either by returning 0
(results in bogus data) or by aborting due to ZEND_UNREACHABLE().  In
either case, this crashes the PHP process.

I'm not quite sure how to fix this multi-threading problem properly;
my suggestion is to just fail the zend_jit_trace() call.  After all,
the whole ZEND_JIT_EXIT_INVALIDATE fix was about reloading modified
scripts, so there's probably no point in this pending zend_jit_trace()
call.

  Fix a memory leak in tracig JIT when the same closure is called through Closure::call() and natively.
 2022-11-22 12:29:36 +03:00
Dmitry Stogov 45cb3f917a Fix a memory leak in tracig JIT when the same closure is called through Closure::call() and natively. 
Closure::call() makes a temporary copy of original closure function, modifies its
scope, resets ZEND_ACC_CLOSURE flag and call it through zend_call_function().
As result the same function may be called with and without
ZEND_ACC_CLOSURE flag, that confuses JIT and may lead to memory leak or
even worse memory errors.

The patch allocates "fake" closure object and keep ZEND_ACC_CLOSURE flag
to always behave in the same way.
