Compatibility:
- Version 1.7.0 is not compatible with versions < 1.7.0 with respect to
packet format because of several fixes related to IETF RFCs that change
the format of ROHC packets. Compatibility may however be required with
the library feature ROHC_COMP_FEATURE_COMPAT_1_6_x.
- The library API is fully compatible with earlier versions.
License/Authors:
- Viveris Technologies for the packet/context repair upon CRC failure.
- Viveris Technologies for better conformance to ROHC standards.
- FWX for ROHCv1 TCP profile.
- Remove the Lulea University of Technology from the authors: code changed
so much since fork that nothing remains from the initial code.
- Remove fuzzer's co-author: he gave ownership and copyright to Didier
Barvaux.
- Add copyright information to all source files.
- Change license from GPLv2+ to LGPLv2.1+
Acknowledgments for bug reports and/or bug fixes:
- Thanks to Friedrich for his help designing the new API function
rohc_feedback_avail_bytes().
- Thanks to Fabrice Bellard for finding several non-conformances to ROHC
standards.
Main changes:
- ROHC protocol:
- Add support for packet/context repair upon CRC failure.
- Add support for extensions on UO-1-ID packets.
- Add support for the ROHCv1 TCP profile (beta quality).
- RTP profile: avoid the Tsc = 0 and no TS bit situation
- Use the Uncompressed profile if IPv4 checksum is incorrect
- Add a compatibility mode with ROHC library 1.6.x.
- Major rework of the API (compatibility preserved), see
https://rohc-lib.org/wiki/doku.php?id=library-migration#api_changes_between_16x_and_17x
- Improve library documentation
- Man pages are now available for public API and tools
- Install ROHC public headers in a rohc/ subdirectory
- New librohc.so available: it gathers all librohc_*.so (old libs still
available)
- Update public headers to be compatible with C++
Build system:
- Refresh HTML and man documentation only if source code changed.
- Remove zcov result files and directories on distclean.
Q&A:
- Parse IP headers/extensions once, factorize many related code
- Rework list compression, especially IPv6 extension headers.
- Add test_lsb_decode unit test
- Add new non-regression test for list compression and context re-use.
- Improve library documentation.
- Reduce graph of header dependencies.
- Many, many small cleanup everywhere.
- Non-regression test: get rid of XML output
- Fix warnings found by the Clang static analyzer.
- Fix warnings found by the Smatch.
- Fix bashisms in non-regression shell script.
- Build library with -Wextra, -Wunreachable-code, -Wshadow,
-Wunused-function and -Wunused-variable compiler flags
- Export only public symbols for libraries.
- Introduce interoperability tests of the ROHC library with other
implementations.
- Make feedback parsing at compressor more robust
Performances:
- Greatly improve the performances of the W-LSB decoding algorithm for
large windows and lossy streams.
- Avoid memory allocation when prepending CID to feedback.
- In case of failure, dump the content of packets only if
--enable-rohc-debug was specified
Applications:
ROHC-over-UDP tunnel:
- Deprecate the ROHC over UDP tunnel. Use the IP/ROHC tunnel instead.
ROHC sniffer:
- Run in brackground mode and use syslog.
- add --daemon/-d option to make daemon mode optional.
- Add option --pidfile/-p to write the child PID in a file.
- Add --disable option to disable one or more ROHC profiles.
- Add Gentoo init script.
- Do not set MAX_CID > ROHC_SMALL_CID_MAX before changing CID type.
- Update statistics output for the TCP profile.
- Fix IPv4 packets with the non-standard 0xffff checksum.
- Do not compare TCP packets with extra padding after TCP options.
- Enable all decompression profiles.
- Correctly close the PCAP dumps upon segfault
ROHC fuzzer:
- Enable all decompression profiles.
- Use correct length for array traces
- Mention truncated traces
- Install in bin/ instead of sbin/
ROHC fuzzer for RTP traffic:
- new application: same as RTP fuzzer but targets RTP streams
- Install in bin/ instead of sbin/
Performances test:
- Use perf to compute elapsed time, no need to be root anymore
- Use 'comp' and 'decomp' as action parameters.
- Enable all decompression profiles.
- Fix build on x86_64
- Install in bin/ instead of sbin/
ROHC stream generator:
- Add a new tool named 'rohc_gen_stream' that generates large
(un)compressed stream for performance testing.
Stats:
- The statistics tests are now an app in app/stats/
