On 32-bit Windows Intel builds the __cdecl and __stdcall calling
conventions are different so labeling the functions that are
exported or assigned to function pointers matters.

Older databases may lack explicitly stored salts where the salt is the default
one. When fetching a client entry for an AS-REQ, add default salts to keys that
lack one.
Whilst Windows does not canonicalize enterprise principal names if the
canonicalize flag is unset, the original specification in
draft-ietf-krb-wg-kerberos-referrals-03.txt says we should. Non-Windows
deployments of Heimdals are unlikely to understand enterprise principal names
in tickets, and are also unlikely to set the canonicalize flag, so this makes
sense. (It was also the behavior prior to moving the name canonicalization
logic into the KDC.)
This reverts commit 1b7e196e66.
It turns out that, contrary to the referrals draft, Windows does not
canonicalize enterprise principal names if the canonicalize KDC option is
unset.
Enterprise principal client names in AS-REQs should always be canonicalized
irrespective of the setting the canonicalize KDC option. Perform this check in
the KDC rather than HDB.
Do not set the HDB_F_GET_KRBTGT flag unless the client actually requested a TGS
principal.
Mirroring the logic recently introduced in the TGS, this patch modifies the KDC
to perform client and server canonicalization itself rather than relying on the
backend to do so. Per RFC 6806, the behavior is slightly different for the AS
in that the setting of the canonicalize flag in the AS-REQ does impact the
returned names in the ticket. In order to support realm canonicalization or
other custom behavior, we allow the backend to force the KDC to canonicalize by
setting the force-canonicalize flag in the returned client or server entries.
e11abf41 added support in libhdb for always dereferencing principal aliases
during an AS-REQ (where dereferencing refers to enabling alias lookups, and
rewriting the returned entry with the alias name unless canonicalization was
enabled).
Due to the KDC setting HDB_F_FOR_AS_REQ for all lookups from the AS, this
allowed aliases on the TGS itself to be dereferenced during an AS-REQ; however,
on presenting the TGT, the TGS would fail to resolve. Creating an explicit TGS
principal for the aliased realm would work (at least prior to c555ed6a), but
this could be confusing to deploy.
This commit changes enables alias dereferencing when HDB_F_GET_ANY is set,
which essentially means dereference whenever the request is coming from the KDC
(as opposed to, say, kadmin).
We also backout c555ed6a, which changed the TGS to always canonicalize the
server realm, as this breaks serving multiple realms from a single KDC, where
server principals in different realms share a single canonical entry.
HDB_F_CANON is now passed to the backend as a hint only, and per RFC 6806 the
principal name is never changed in TGS replies. (However, for Samba interop,
backends can override this by setting the force-canonicalize HDB flag.)
Refactor plugin framework to use a single list of loaded plugins; add a new
plugin API where DSOs export a load function that can declare dependencies and
export multiple plugins; refactor kadm5 hook API to use krb5 plugin framework.
More information in krb5-plugin(7).
Adds support for "hard" aliases when initially authenticating, that is,
allowing a client or server principal to be known by many names without
requiring that the client support name canonicalization.
In order to avoid changing the behavior for other backends such as Samba, this
is implemented in the HDB backend rather than the KDC.
To use, add an alias for both the client and TGS ("krbtgt") principals using
kadmin. This behavior is unchanged if name canonicalization is enabled.
Heimdal will refuse to create new entries when an entry already exists even
if said entry has no kerberos info and is a new entry.
This patch fixes this issue by allowing object modifications even if the
flags disallow them when we are inserting a new principal on the database.

Must export hdb_generate_key_set_password_with_ks_tuple() on Windows
which was introduced in 4303174a49.
Change-Id: Iea2993a17aba44c7cb0360716138c26239254e05
The change to the signature of hdb_generate_key_set_password() in
Heimdal 7.1 broke API/ABI compatibility with previous releases. We
fix this by renaming it hdb_generate_key_set_password_with_ks_tuple()
and creating a new hdb_generate_key_set_password() which calls our
new function with zeroes for the added arguments.
Issue #246https://github.com/heimdal/heimdal/issues/246
If some external library lives in a directory in which Heimdal is
already installed, we may pick up LD_LIBRARY_PATH Heimdal objects
from a different release. Move the external deps to the end, to
ensure a more appropriate LD_LIBRARY_PATH.
Commit 4b6bd40106 made hdb_ldap_create and
hdb_ldapi_create static in the OPENLDAP_MODULE case. However, by
failing to leave a blank line between the static and the function
declaration the perl program that produces the hdb-protos.h file
skips the functions.
Add appropriate spacing.

read_master_keytab() should always return with *mkey == NULL on
failure. Doing otherwise can result in memory leaks or use of
an uninitialized pointer.

This fixes the following problems from #210:
- hdb_ldap doesn't load even when installed correctly
- loadable hdb backends not listed by kdc --builtin-hdb
Not fixed:
- hdb_ldap.so not installed in plugin dir
In hdb_ldap_common() the test
if (search_base == NULL && search_base[0] == '\0')
error handling ...
must be
if (search_base == NULL || search_base[0] == '\0')
error handling ...

This adds a new backend for libhcrypto: the OpenSSL backend.
Now libhcrypto has these backends:
- hcrypto itself (i.e., the algorithms coded in lib/hcrypto)
- Common Crypto (OS X)
- PKCS#11 (specifically for Solaris, but not Solaris-specific)
- Windows CNG (Windows)
- OpenSSL (generic)
The ./configure --with-openssl=... option no longer disables the use of
hcrypto. Instead it enables the use of OpenSSL as a (and the default)
backend in libhcrypto. The libhcrypto framework is now always used.
OpenSSL should no longer be used directly within Heimdal, except in the
OpenSSL hcrypto backend itself, and files where elliptic curve (EC)
crypto is needed.
Because libhcrypto's EC support is incomplete, we can only use OpenSSL
for EC. Currently that means separating all EC-using code so that it
does not use hcrypto, thus the libhx509/hxtool and PKINIT EC code has
been moved out of the files it used to be in.
The hdb_method functions cannot be KRB5_LIB_CALL as lib/hdb is not
lib/krb5. KRB5_LIB_CALL will be inconsistently defined.
This inconsistency resulted in crashes of test_hdbplugin on 32-bit
Windows.
