hetzels> Here's a corrected patch for the Makefile. PATCH* should be below MASTER*
Please be careful to apply my IPv6 patch. Though SASL API uses struct
sockaddr * for an interface, it may not been filled. Originally, SASL
refer only sin_addr field, and it is suffucient to support only IPv4.
However, to support IPv6, we need it filled. Some applications may
pass struct sockaddr * without filling field such as sa_family or
sa_len. Though the code has a workaround, it is still ad-hoc.
There is no complete solution without modifying applications. I dunno
if there is such broken application out there. At least, the sample
codes you can see in cyrus-sasl is broken.
Further, my IPv6 patch helps only the following case:
- You are using KerberosIV, and
- The application accepts an IPv4 connection as an IPv4-mapped
IPv6 address.
At least, cyrus-sasl port doesn't enable KerberosIV nor doesn't use
IPv4-mapped IPv6 address at all. Even if you enable KerberosIV
support, it is still okay.
Sincerely,
