In the OpenSSL and NSS modules, remove many of the headers and sources providing functionality which isn't needed by lib/crypto/krb any more (direct interfaces to MD4, MD5, and SHA-1 hashing, as well as DES weak key testing). Change most Makefile.ins to only include headers from lib/crypto/krb and lib/crypto/$(CRYPTO_IMPL), instead of from many different directories. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24677 dc483132-0cff-0310-8789-dd5450dbe970

| | | | | | | | | | | | enc_provider, for consistency with string-to-key and the place of implementation (other enc_provider functions are implemented in the back end, but random-to-key handlers are in krb). Use a single handler for non-DES/DES3 enctypes since it's always just directly copying the bits. Collapse the three implementations (des, des3, and direct) into random_to_key.c, as they're very short, and eliminate the lib/crypto/krb/rand2key directory. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24669 dc483132-0cff-0310-8789-dd5450dbe970

* Fix Windows buildGreg Hudson2010-11-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair the Windows build. Tested with the prepare-on-Unix method. Some specific changes include: * Removed the IPC finalizer (no longer used after r20787) from ccapi/lib/ccapi_ipc.c, as it was creating a difficult dependency chain for the pingtest build in ccapi/test. Also updated pingtest to use the k5_ipc_stream interfaces since cci_stream is gone. * Reverted the apparently non-functional r20277. * klist -V prints just "Kerberos for Windows", since it has no access to PACKAGE_NAME and PACKAGE_VERSION from autoconf. This should be addressed correctly. * krb5, telnet, gssftp, and NIM are removed from the build. * Some files had CRLFs; these were replaced with LFs and the svn:eol-style property set on the files. Otherwise the CRLFs became CRCRLFs after the zip transfer. * Windows does not have opendir/readdir, so added Windows code to prof_parse.c for includedir. Probable fodder for a libkrb5support portability shim. ticket: 6826 target_version: 1.9 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24533 dc483132-0cff-0310-8789-dd5450dbe970

| | | | | | | | | | Failure to set the enctype before invoking krb5_k_create_key results in potential memory leak. ticket: 6628 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23612 dc483132-0cff-0310-8789-dd5450dbe970
* krb5int_derive_key results in cache with uninitialized valuesEzra Peisach2010-01-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | krb5int_derive_key creates a temporary keyblock to add to the derived cache. krb5_k_free_key will iterate over the derived keys and for ones with cache will lookup the enctype for the key_cleanup handler. Unfortunatly, there isn't a keyblock init function that does not allocate the keyblock - as I suspect this problem will appear in other places. The valgrind log of this problem is: ==7281== Conditional jump or move depends on uninitialised value(s) ==7281== at 0x40E9AE8: find_enctype (etypes.h:81) ==7281== by 0x40E9C96: krb5_k_free_key (key.c:91) ==7281== by 0x40E9C52: krb5_k_free_key (key.c:86) ==7281== by 0x40EBB00: krb5_c_prf (prf.c:87) ==7281== by 0x40E7B1B: prf_plus (cf2.c:77) ==7281== by 0x40E7CE6: krb5_c_fx_cf2_simple (cf2.c:125) ==7281== by 0x804899C: main (t_cf2.c:70) ==7281== with memory leaks. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23608 dc483132-0cff-0310-8789-dd5450dbe970

* Restructure the crypto checksum implementation to minimizeGreg Hudson2009-12-103-32/+25
| | | | | | | | | | | | | | | | | | | | | dependencies on the internals of modules. * Keyhash providers are gone. * The cksumtypes table contains checksum and verify functions, similar to the etypes encrypt and decrypt functions. New checksum functions parallel the old keyhash providers, and there are also functions for unkeyed and derived-key HMAC checksums. * The flags field is now used to indicate whether a checksum is unkeyed, but not whether it is a derived-key HMAC checksum. * The descbc checksum is handled through a new enc_provider function which calculates a CBC MAC. The OpenSSL module does not implement the CBC MAC function (it didn't implement descbc before). builtin/des could probably get rid of f_cksum.c (the old DES CBC routine) with some alterations to string2key.c. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23462 dc483132-0cff-0310-8789-dd5450dbe970

* Consolidate the IOV and non-IOV encryption/decryption code paths, andGreg Hudson2009-12-048-785/+182
| | | | | | | | | | | | | | | | | | | | | | | | drop the _iov suffix from most encryption- and decryption-related functions. The enc_provider encrypt and decrypt functions take IOVs, as do the enctype entries in etypes.c, and there are no separate encrypt_iov or decrypt_iov functions. aead_provider is gone. Enctype functions now take pointers to the enctype entry instead of pointers to the enc/hash/aead providers; this allows dk_encrypt and dk_decrypt to be polymorphic in the length function they use now that AES and DES3 can't differentiate by aead provider. aes_string_to_key needed to be moved into the krb/ fold for this since it's an enctype function; it was duplicated between builtin/ and openssl/ before. This leaves openssl/aes empty; the build system currently demands that all modules have the same directory structure, so the directory and Makefile will stick around for now. Three separate copies of the derive_random logic are also now consolidated into one. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23444 dc483132-0cff-0310-8789-dd5450dbe970
