krb5_get_next() and krb5_get_cache_next() do not check for krb5_kcm_call()
returning non-zero before accessing the repsonse data; they only handle the
case where the return value is KRB5_CC_END.
Return immediately if the return value of krb5_kcm_call() is not KRB5_CC_END or
0. This was fixed in the Apple code.
Some compilers with -Wstring-concatenation enabled warned about a suspicious
concatenation of string literals in the initialization of the GSS-API error
message array.
At the expense of a long line, avoid this warning but explicitly concatenating
the offending string literal.
Fixes: #775
vis.h is not built on platforms (such as macOS) that already have
that header, which resulted in prototypes for Heimdal-specific
vis.h extensions being absent.
Move those prototypes to a separate header, vis-extras.h, which
must be explicitly included in order to use the Heimdal extensions.
- Don't log "Request from wrong address (ignoring)".
- Add "wrongaddr=yes" kv to final log message.
- Add request and ticket addresses (up to 3) to final log message.
If a DB does not already exist, ipropd-slave will use the compiled
default, which is not necessarily what is desired or configured in
`[kdc]`.
This change makes `hdb_default_db()` return the first dbanme in the
`[kdc]` configuration, falling back on `HDB_DEFAULT_DB`.
Also, this adds a `--database` option to `ipropd-slave`.
The codegen backend is faster than the template backend, even for
modules that don't use IOS. On x64 we see the template backend being
4% slower for TGS requests using the kdc-tester program.
So let's build both, libasn1 (codegen) and libasn1template when
configured with --disable-asn1-templating, but make sure that the
asn1_print utility is linked with libasn1template.
Eventually we'll want to either optimize the template backend better,
or add IOS and JSON printing support to the codegen backend.
