[openssl-dev] Missing const EC_KEY *EC_KEY_dup(EC_KEY *src);

[Richard Moore]

Shouldn't this be  EC_KEY *EC_KEY_dup(const EC_KEY *src);

Cheers

I think the reason it is not is because the EC_KEY has an ENGINE* and that can't be const.

Sigh, C needs 'mutable' :)

The pointer to ENGINE will be const, yes, but not the ENGINE content
itself, as if it was defined like this:

ENGINE * const engine;

What happens is that the ENGINE pointer is copied to the new
structure, and the ENGINE itself will work perfectly, both in the
source EC_KEY and the new one.

So there's no actual reason not to have const there. It does,
however, mean that we need to add const in a few more places. Now
many at all, actually, it took me 5 minutes. PR coming tomorrow.

Cheers,
Richard

I meant to ask, should I make tickets for this and the missing DSA_bits()?

Cheers

Tickets. Or ideally PR with code:)
