-Changelog
-
-1.3.20
-
- Lots of changes. 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
