Using EXT_IA5STRING

[daurnimator]

The expansion of the public macro EXT_IA5STRING uses the private functions i2s_ASN1_IA5STRING and s2i_ASN1_IA5STRING.
This was fixed in OpenSSL 1.0.2 but is still missing from libressl.

Thanks. Have you got a reference to code that actually uses this macro?

Other than the (new) code I'm working on right now, no.
I ran into it as I'm writing the new code against OpenSSL 1.1.0; but now I'm backporting to LibreSSL.

I'm backporting to LibreSSL.

FYI, my first take at the compat code is:

#define i2s_ASN1_IA5STRING (X509V3_EXT_get_nid(NID_netscape_renewal_url)->i2s)
#define s2i_ASN1_IA5STRING (X509V3_EXT_get_nid(NID_netscape_renewal_url)->s2i)
