Tighten up all of the call sites of hx509_request_get_san()
to free the output string returned upon failure.
Use frees(&s) instead of free(s); s = NULL;.

Now that ETYPE_xxx names are macros to the KRB5_ENCTYPE_xxx
symbols there is no longer a need to cast to (krb5_enctype).

Remove hdb_entry_ex and revert to the original design of hdb_entry (except with
an additional context member in hdb_entry which is managed by the free_entry
method in HDB).
Decorate HDB_entry with context and move free_entry callback into HDB structure
itself. Requires updating hdb_free_entry() signature to include HDB parameter.
A follow-up commit will consolidate hdb_entry_ex (which has a single hdb_entry
member) into hdb_entry.
This is not a very good fix, though the warnings remain. Such errors
can in principle be a problem because in C there is no standard enum
sizing.
In this case we have two enums with the same elements and so the same
size, so it's clearly not a problem.
Recent auditing changes (b1dcc1a4) introduced a leak into pa_enc_ts_validate()
where the encryption type name and error message could be leaked.
This patch fixes a compile error in the original commit.
Add some notes about the KDC plugin API contract, and require plugins to
explicitly indicate which version of the API they support (remove the macro
alias for the current version).
r->canon_client_princ is always an alias to r->client->entry.principal in the
AS, but use it for consistency with the TGS. (In the TGS, it may also come from
te PAC.)
Move the Services for User (SFU/S4U) implementation -- protocol transition and
constrained delegation -- into its own compilation unit, with an interface that
only takes an astgs_request_t, so it can be easily factored out into a plugin
module in the future.
This refactoring is also careful to update all client names in the request
structure after the SFU/S4U validation has successfully completed.
Instead of having distinct preauth success/failure events for different
mechanisms, have a single event; the mechanism can be disambiguated by querying
the HDB_REQUEST_KV_PA_NAME key.
Note: there is still an explicit event for long-term key-based success/failure
in order to help the backend implement lockout.
Audit failure (HDB_AUTH_EVENT_PREAUTH_FAILED) in the main preauth loop, rather
than in each mechanism. Success is still audited in the mechanism to allow
client pre-authentication success to be noted even if something subsequent
(e.g. encoding a reply, memory allocation) fails. The generic catch-all for
success remains.
ASTGS_REQUEST_DESC_COMMON_ELEMENTS should not terminate in a semi-colon;
the consuming structure should include it. This is consistent with
HEIM_SVC_REQUEST_DESC_COMMON_ELEMENTS. This fixes the build on Windows.
Annotate libkdc APIs with KDC_LIB_{CALL,FUNCTION} to ensure correct calling
convention and optimized DLL importing on Windows.
Ensure Windows and libtool export tables are consistent.
Now heim_audit_addkv() correctly supports multiple values, the other functions
that (by design) replace existing values with a single value should use the
heim_audit_setkv prefix.
A subsequent commit could add variants that support multiple values for
non-string types.
Rename the "windc" plugin API to the more general "kdc" plugin API, for two
reasons: the Heimdal KDC uses the Windows PAC even when not emulating a domain
controller, and the plugin API has accreted methods that are not specific to
emulating a domain controller (such as referral_policy and finalize_reply).
Allow the windc plugin to also implement an audit callback. As part of this
change, both the HDB and windc audit function signatures are changed to return
void.
Active Directory/Samba-specific referral policy should be implemented by a
windc plugin, not in the main KDC code. It looks like it probably isn't
necessary at all if Samba wishes to bypass Heimdal's referral handling.
This reverts commit 6f0cafa6cf.
Add a referral policy hook to the TGS as a more elegant way of resolving
referral detection for Samba). The hook can either rewrite the server_princ in
the request, or it can return an error to disable built-in referral processing.
