Context: The macro `MBEDTLS_ECP_BUDGET()` is called before performing a number of potentially time-consuming ECC operations. If restartable ECC is enabled, it wraps a call to `mbedtls_ecp_check_budget()` which in turn checks if the requested number of operations can be performed without exceeding the maximum number of consecutive ECC operations. Issue: The function `mbedtls_ecp_check_budget()` expects a the number of requested operations to be given as a value of type `unsigned`, while some calls of the wrapper macro `MBEDTLS_ECP_BUDGET()` use expressions of type `size_t`. This rightfully leads to warnings about implicit truncation from `size_t` to `unsigned` on some compilers. Fix: This commit makes the truncation explicit by adding an explicit cast to `unsigned` in the expansion of the `MBEDTLS_ECP_BUDGET()` macro. Justification: Functionally, the new version is equivalent to the previous code. The warning about truncation can be discarded because, as can be inferred from `ecp.h`, the number of requested operations is never larger than 1000. |
