The functions mbedtls_pk_sign(), mbedtls_pk_sign_restartable(), mbedtls_ecdsa_write_signature() and mbedtls_ecdsa_write_signature_restartable() now take an extra parameter indicating the size of the output buffer for the signature. No change to RSA because for RSA, the output size is trivial to calculate. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>

Extra parameter for the output buffer size
|
|
------------------------------------------
|
|
|
|
The following functions now take an extra parameter indicating the size of the output buffer:
|
|
|
|
* `mbedtls_ecdsa_write_signature()`, `mbedtls_ecdsa_write_signature_restartable()`
|
|
* `mbedtls_pk_sign()`, `mbedtls_pk_sign_restartable()`
|
|
|
|
The requirements for the output buffer have not changed, but passing a buffer that is too small now reliably causes the functions to return an error, rather than overflowing the buffer.
