Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Date: Wed Feb 1 11:27:42 2023 +0000 tools/ocaml/libs: Fix memory/resource leaks with caml_alloc_custom() All caml_alloc_*() functions can throw exceptions, and longjump out of context. If this happens, we leak the xch/xce handle. Reorder the logic to allocate the the Ocaml object first.

From the manual: https://ocaml.org/manual/intfc.html#ss:parallel-execution-long-running-c-code "After caml_release_runtime_system() was called and until caml_acquire_runtime_system() is called, the C code must not access any OCaml data, nor call any function of the run-time system, nor call back into OCaml code." More than what the manual says, the intf pointer is (potentially) invalidated by caml_enter_blocking_section() if another thread happens to perform garbage collection at just the right (wrong) moment. Rewrite the logic. There's no need to stash data in the Ocaml object until the success path at the very end. Fixes: 8b7ce06a2d34 ("ocaml: Add XC bindings.")

It modified the C stub to add a 4th parameter without an equivalent adjustment in the Ocaml side of the bindings. In 64bit builds, this causes us to dereference whatever dead value is in %rcx when trying to interpret the rflags parameter. This has gone unnoticed because Xapi doesn't use this binding (it has its own), but unbreak the binding by passing RDM_RELAXED unconditionally for now (matching the libxl default behaviour).

From the manual: https://ocaml.org/manual/intfc.html#ss:parallel-execution-long-running-c-code "After caml_release_runtime_system() was called and until caml_acquire_runtime_system() is called, the C code must not access any OCaml data, nor call any function of the run-time system, nor call back into OCaml code." Previously, the value was a naked C pointer, so dereferencing it wasn't "accessing any Ocaml data", but the fix to avoid naked C pointers added a layer of indirection through an Ocaml Custom object, meaning that the common pattern of using _H() in a blocking section is unsafe. In order to fix: * Drop the _H() macro and replace it with a static inline xce_of_val(). * Opencode the assignment into Data_custom_val() in the two constructors. * Rename "value xce" parameters to "value xce_val" so we can consistently have "xenevtchn_handle *xce" on the stack, and obtain the pointer with the GC lock still held.

As a consequence, we're allocating 4 or 8 times too much memory. Ocaml has a helper, Wsize_bsize(), but it truncates cases which aren't an exact multiple. Use a BUILD_BUG_ON() to cover the potential for truncation, as there's no rounding-up form of the helper. Fixes: 8b7ce06a2d34 ("ocaml: Add XC bindings.")

Unknown entries in the config file would be ignored on startup normally, add a strict --config-test that live-update can use to check that the config file is valid *for the new binary*.

However the operation here really is read-only: we read from the string and write it to the ring, so the C stub should implement the read-only string version, and if needed we could use Bytes.unsafe_to_string to be able to send 'bytes'. However that is not necessary as the 'bytes' version is dropped above.

However it does make it clearer that what we have here is not a regular OCaml value, but one allocated with Abstract_tag or Custom_tag, and follows the example from the manual more closely: https://v2.ocaml.org/manual/intfc.html#ss:c-outside-head It also makes it clearer that these modules have been reviewed for compat with OCaml 5.0. We cannot use OCaml finalizers here, because we want exact control over when to unmap these pages from remote domains. No functional change.
