In client_connect() getaddrinfo() stores the head of the allocated
addrinfo structure list in 'res0'. 'res' is used to walk the list
and will be NULL at the end of the for() loop when freeaddrinfo(res)
is executed. Pass 'res0' to freeaddrinfo() instead of 'res'.

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.
On Windows a file descriptor is an int value allocated by the
local module instance of the C Run Time Library. A socket handle is a
SOCKET value allocated by a Winsock Provider for the requested family and
protocol. These two values cannot be mixed and there is no mechanism for
converting between the two. The _get_osfhandle() and _open_osfhandle()
functions can work with a standard HANDLE (file, pipe, etc) but cannot be
used for a SOCKET.
The Heimdal krb5_storage_from_fd() routine counted on the osf conversion
functions working on SOCKET values. Since they do not any attempt to call
krb5_storage_from_fd() on a socket resulted in an assertion being thrown
by the C RTL.
Another problem is SOCKET value truncation when storing a 64-bit value
into a 32-bit int.
To address these problems a new krb5_storage_from_socket() routine is
introduced. This routine setups a krb5_storage that stores a socket value
as a rk_socket_t and provides a set of helper routines that always use
network ready functions.
The krb5_storage_from_fd() routines no longer use net_read() and
net_write() but provide helpers that follow their logic so that pipes can
be processed.
All call sites that allocate a socket now store the socket as rk_socket_t
and call krb5_storage_from_socket().
All locations that previously called the bare close() on a socket value
now call rk_closesocket().

To stop the errors when building concurrently, we make a number of
changes:
1. stop including generated files in *_SOURCES,
2. make *-protos.h and *-private.h depend on the *_SOURCES,
3. make all objects depend on *-{protos,private}.h,
4. in a few places change dir/header.h to $(srcdir)/dir/header.h,
This appears to work for me with make -j16 on a 4-way box.
This wasn't having the intended effect because after we #include
config.h and #undef ENABLE_PTHREAD_SUPPORT we then #include other
headers that also #include config.h. I've moved this lower so that
it has the effect that appears to be intended but the correct answer
may be to make it work but this will require #including pthread.h
as the build fails with -Werror when pthread functions are called.
appl/test/tcp_server and gssapi_server try to open the keytab file only when processing a connection.
This patch verifies the existence of the keytab file on program startup, so that troubleshooting is easier. In addition it adds some comments.

We turn on a few extra warnings and fix the fallout that occurs
when building with --enable-developer. Note that we get different
warnings on different machines and so this will be a work in
progress. So far, we have built on NetBSD/amd64 5.99.64 (which
uses gcc 4.5.3) and Ubuntu 10.04.3 LTS (which uses gcc 4.4.3).
Notably, we fixed
1. a lot of missing structure initialisers,
2. unchecked return values for functions that glibc
marks as __attribute__((warn-unused-result)),
3. made minor modifications to slc and asn1_compile
which can generate code which generates warnings,
and
4. a few stragglers here and there.
We turned off the extended warnings for many programs in appl/ as
they are nearing the end of their useful lifetime, e.g. rsh, rcp,
popper, ftp and telnet.
Interestingly, glibc's strncmp() macro needed to be worked around
whereas the function calls did not.
We have not yet tried this on 32 bit platforms, so there will be
a few more warnings when we do.
On NetBSD, cgetent has a prototype of ``const char *const *'' for
argument two. Many other OSes have ``char **''. It seems that
gcc will generate a warning if you pass a char ** to it. Casting
the value to void avoids this warning.

Added heim_db_*() entry points for dealing with databases, and
make krb5_aname_to_localname() use it.
The following enhancements to libheimbase are included:
- Add heim_data_t and heim_string_t "reference" variants to
avoid memory copies of potentially large data/strings.
See heim_data_ref_create() and heim_string_ref_create().
- Added enhancements to heim_array_t to allow their use for
queues and stacks, and to improve performance. See
heim_array_insert_value().
- Added XPath-like accessors for heim_object_t. See
heim_path_get(), heim_path_copy(), heim_path_create(), and
heim_path_delete(). These are used extensively in the DB
framework's generic composition of ACID support and in the
test_base program
- Made libheimbase more consistent with Core Foundation naming
conventions. See heim_{dict, array}_{get, copy}_value() and
heim_path_{get, copy}().
- Added functionality to and fixed bugs in base/json.c:
- heim_serialize();
- depth limit for JSON parsing (for DoS protection);
- pretty-printing;
- JSON compliance (see below);
- flag options for parsing and serializing; these are needed
because of impedance mismatches between heim_object_t and
JSON (e.g., heim_dict_t allows non-string keys, but JSON
does not; heimbase supports binary data, while JSON does
not).
- Added heim_error_enomem().
- Enhanced the test_base program to test new functionality and
to use heim_path*() to better test JSON encoding. This
includes some fuzz testing of JSON parsing, and running the
test under valgrind.
- Started to add doxygen documentation for libheimbase (but doc
build for libheimbase is still incomplete).
Note that there's still some incomplete JSON support:
- JSON string quoting is not fully implemented;
- libheimbase lacks support for real numbers, while JSON has
it -- otherwise libheimbase is a superset of JSON,
specifically in that any heim_object_t can be a key for an
associative array.
The following DB backends are supported natively:
- "sorted-text", a binary search of sorted (in C locale), flat
text files;
- "json", a backend that stores DB contents serialized as JSON
(this is intended for configuration-like contents).
The DB framework supports:
- multiple key/value tables per-DB
- ACID transactions
The DB framework also natively implements ACID transactions for
any DB backends that a) do not provide transactions natively, b)
do provide lock/unlock/sync methods (even on Windows). This
includes autocommit of DB updates outside transactions.
Future DB enhancements may include:
- add backends for various DB types (BDB, CDB, MDB, ...);
- make libhdb use heim_db_t;
- add a command-line tool for interfacing to databases via
libheimbase (e.g., to get/set/delete values, create/copy/
backup DBs, inspect history, check integrity);
- framework-level transaction logging (with redo and undo
logging), for generic incremental replication;
- framework-level DB integrity checking.
We could store a MAC of the XOR of a hash function applied to
{key, value} for every entry in the DB, then use this to check
DB integrity incrementally during incremental replication, as
well as for the whole DB.
