Thanks to Jeff Chan for catching a memory leak and - helping track down the endian issues with the SSRCs. - -1.3.8 - - This is an interim release. Several little-endian bugs were identified - and fixed; this means that we can use intel/linux for development again. - - Cleaned up sha1 and hmac code significantly, got rid of some excess - functions and properly documented the fuctions in the .h files. - - Eliminated some vestigial files. - - There is a SIGBUS error in the AES encrypt function on sparc - (observed on both solaris and openbsd) with gcc 2.95. Was unable to - find bad pointer anywhere, so I'm wondering if it isn't a compiler - problem (there's a known problem whose profile it fits). It doesn't - appear on any other platform, even in the cipher_driver stress - tests. - - Planned changes - - Change interface to nonces (xtd_seq_num_t) so that it uses - network byte ordering, and is consistent with other arguments. - - -1.3.6 - - Changed /dev/random (in configure.in and crypto/rng/rand_source.c) to - /dev/urandom; the latter is non-blocking on all known platforms (which - corrects some programs that seem to hang) and is actually present on - Open BSD (unlike /dev/random, which only works in the presence of - hardware supported random number generation). - - Added machine/types.h case in include/integers.h. - -1.3.5 - - Removing srtp_t::template and stream_clone(). - - Adding a new policy structure, which will reflect a complete SRTP - policy (including SRTCP). - - This version is *incomplete* and will undergo more changes. It is - provided only as a basis for discussion. - -1.3.4 - - Removed tmmh.c and tmmh.h, which implemented version one of TMMH. - - Changed srtp_get_trailer_length() to act on streams rather than - sessions, and documented the macro SRTP_MAX_TRAILER_LEN, which should - usually be used rather than that function. - - Removed 'salt' from cipher input. - - Changed rdbx to use err.h error codes. - - Changed malloc() and free() to xalloc() and xfree; these functions - are defined in crypto/kernel/alloc.c and declared in - include/alloc.h. - - Added 'output' functions to cipher, in addition to 'encrypt' - functions. It is no longer necessary to zeroize a buffer before - encrypting in order to get keystream. - - Changed octet_string_hex_string() so that "times two" isn't needed - in its input. - - Added crypto_kernel_init() prior to command-line parsing, so that - kernel can be passed command-line arguments, such as "-d - debug_module". This was done to for the applications - test/srtp-driver, test/kernel-driver, and test/ust-driver. - - Improved srtp_init_aes_128_prf - wrote key derivation function - (srtp_kdf_t). - - Add the tag_len as an argument to the auth_compute() function, but - not the corresponding macro. This change allows the tag length for - a given auth func to be set to different values at initialization - time. Previously, the structure auth_t contained the - output_length, but that value was inaccessible from hmac_compute() - and other functions. - - Re-named files from a-b.c to a_b.c. in order to help portability. - - Re-named rijndael to aes (or aes_128 as appropriate). - - -1.2.1 - - Changes so that 1.2.0 compiles on cygwin-win2k. - - Added better error reporting system. If syslog is present on the - OS, then it is used. - - -1.2.0 Many improvements and additions, and a fex fixes - - Fixed endian issues in RTP header construction in the function - rtp_sendto() in srtp/rtp.c. - - Implemented RIJNDAEL decryption operation, adding the functions - rijndael_decrypt() and rijndael_expand_decryption_key(). Also - re-named rijndael_expand_key() to rijndael_expand_encryption_key() - for consistency. - - Implemented random number source using /dev/random, in the files - crypto/rng/rand_source.c and include/rand_source.h. - - Added index check to SEAL cipher (only values less than 2^32 are - allowed) - - Added test case for null_auth authentication function. - - Added a timing test which tests the effect of CPU cache thrash on - cipher throughput. The test is done by the function - cipher_test_throughput_array(); the function - cipher_array_alloc_init() creates an array of ciphers for use in - this test. This test can be accessed by using the -a flag to - the application cipher-driver in the test subdirectory. - - Added argument processing to ust-driver.c, and added that app to - the 'runtest' target in Makefile.in. - - A minor auth_t API change: last argument of auth_init() eliminated. - - -1.0.6 A small but important fix - - Fixed srtp_init_aes_128_prf() by adding octet_string_set_to_zero() - after buffer allocation. - - Eliminated references to no-longer-existing variables in debugging - code in srtp/srtp.c. This fixes the compilation failure that - occured when using PRINT_DEBUG in that file. - - Corrected spelling of Richard Priestley's name in credits. Sorry - Richard! - - -1.0.5 Many little fixes - - Fixed octet_string_set_to_zero(), which was writing one - more zero octet than it should. This bug caused srtp_protect() - and srtp_unprotect() to overwrite the byte that followed the - srtp packet. - - Changed sizeof(uint32_t) to srtp_get_trailer_length() in - srtp-driver.c. This is just defensive coding. - - Added NULL check to malloc in srtp_alloc(). - - -1.0.4 Many minor fixes and two big ones (thanks for the bug reports!) - - Removed 'ssrc' from the srtp_init_aes_128_prf() function argument - list. This is so that applications which do not a priori know the - ssrc which they will be receiving can still use libsrtp. Now the - SSRC value is gleaned from the rtp header and exored into the - counter mode offset in the srtp_protect() and srtp_unprotect() - functions, if that cipher is used. This change cascaed through - many other functions, including srtp_init_from_hex(), - srtp_sender_init() and srtp_receiver_init() in rtp.c, and also - changing the CLI to test/rtpw. In the future, another function - call will be added to the library that enables multiple ssrc/key - pairs to be installed into the same srtp session, so that libsrtp - works with multiple srtp senders. For now, this functionality is - lacking. - - Removed the GDOI interface to the rtpw demo program. This will be - added again at a later date, after the SRTP and GDOI distributions - stabilize. For now, I've left in the GDOI #defines and autoconf - definitions so that they'll be in place when needed. - - Updated tmmhv2_compute() so that it didn't assume any particular - alginment of the output tag. - - Changed bit field variables in srtp.h to unsigned char from - unsigned int in order to avoid a potential endianness issue. - - Fixed rdbx_estimate_index() to handle all input cases. This solves - the now notorious "abaft" bug in the rtpw demo app on linux/intel, - in which spurious replay protection failures happen after that word - is received. - - Added ntohs(hdr->seq) to srtp_protect and srtp_unprotect, removed - from rijndael_icm_set_segment(). - - Added error checking and handling to srtp_sender_init() and - srtp_receiver_init(). - - Changed srtp_alloc() so that it does what you'd expect: allocate an - srtp_ctx_t structure. This hides the library internals. - - -1.0.1 Many minor fixes - - Added cipher_driver_buffer_test(...) to test/cipher-driver.c. This - function checks that the byte-buffering functions used by a cipher - are correct. - - Fixed SunOS/Solaris build problems: added HAVE_SYS_INT_TYPES_H and - changed index_t to xtd_seq_num_t (see include/rdbx.h). - - Fixed SEAL3.0 output byte buffering, added byte-buffering test to - cipher/cipher-driver.c. - - Fixed roc-driver so that the non-sequential insertion test - automatically recovers from bad estimates. This was required to - prevent spurious failures. - - Made rdbx_estimate_index(...) function smarter, so that initial RTP - sequence numbers greater than 32,768 don't cause it to estimate the - rollover counter of 0xffffffff. - - -1.0.0 Initial release - |
