| H A D | adf_fw_counters.c | 141f12be Fri Sep 22 17:54:33 GMT 2023 Kees Cook <keescook@chromium.org> crypto: qat - Annotate struct adf_fw_counters with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct adf_fw_counters.
