Detailed Description

Portable SPNEGO implementation.

This is part of a portable implementation of the SPNEGO protocol (RFCs 2478 and 4178). This implementation uses the RFC 4178 ASN.1 module but is not a full implementation of the RFC 4178 protocol; at the moment, we only support GSS-TSIG with Kerberos authentication, so we only need enough of the SPNEGO protocol to support that.

The files that make up this portable SPNEGO implementation are:

• spnego.c (this file)
• spnego.h (API SPNEGO exports to the rest of lib/dns)
• spnego.asn1 (SPNEGO ASN.1 module)
• spnego_asn1.c (routines generated from spngo.asn1)
• spnego_asn1.pl (perl script to generate spnego_asn1.c)

Everything but the functions exported in spnego.h is static, to avoid possible conflicts with other libraries (particularly Heimdal, since much of this code comes from Heimdal by way of mod_auth_kerb).

spnego_asn1.c is shipped as part of lib/dns because generating it requires both Perl and the Heimdal ASN.1 compiler. See spnego_asn1.pl for further details. We've tried to eliminate all compiler warnings from the generated code, but you may see a few when using a compiler version we haven't tested yet.
