Compatibility:
- Version 2.2.0 is not guaranteed to be 100% compatible with previous versions
with respect to IR packet format of the ROHCv1 IP-only, ESP, UDP,
UDP-Lite profiles because the behavior of the D flag was made conforme
to RFC 3095.
- The library API is compatible with versions 2.0.x and 2.1.x. The
following headers/types/functions were added/modified for ROHCv2:
- header <rohc/rohc_profiles.h> was added, it is included by
<rohc/rohc.h>, so no change is required by applications.
- rohc_profile_t to add the ROHCv2 profile identifiers
- rohc_comp_enable_profile() to accept ROHCv2 profiles
- rohc_comp_enable_profiles() to accept ROHCv2 profiles
- rohc_comp_disable_profile() to accept ROHCv2 profiles
- rohc_comp_disable_profiles() to accept ROHCv2 profiles
- rohc_decomp_enable_profile() to accept ROHCv2 profiles
- rohc_decomp_enable_profiles() to accept ROHCv2 profiles
- rohc_decomp_disable_profile() to accept ROHCv2 profiles
- rohc_decomp_disable_profiles() to accept ROHCv2 profiles
- rohc_comp_set_reorder_ratio() to set the ROHCv2 reordering ratio
- rohc_profile_is_rohcv1() to determine if profile is ROHCv1
- rohc_profile_is_rohcv2() to determine if profile is ROHCv2
- rohc_profile_get_other_version() to determine the related profile in
the other ROHC version
- The applications gained a --rohc-version parameter to use ROHCv1 or
ROHCv2 profiles. They defaults to ROHCv1 for compatibility reasons.
License/Authors:
- Developing Solutions helped Viveris Technologies to implement the ROHCv2
IP-only, ESP and UDP profiles.
- Developing Solutions helped Viveris Technologies about the Static Chain
Termination support.
- Mikhail Gruzdev contributed Linux kernel fixes.
- Selvaganesan Murugesan reported the conformance problem with the D flag.
- Bi-Ruei Chiu contribued GCC-7 fixes.
Main changes:
- ROHCv2 IP-only, IP/ESP and IP/UDP profiles,
- interoperability: improve conformance to ROHC standards:
- RFC3095: handle the IR D flag of IP-only, UDP, ESP, and UDP-Lite profiles
- RFC3843: add support for Static Chain Termination
- preliminary Wireshark dissector in Lua
Bug fixes:
- TCP profile: do not skip MSN 65535 at compressor
- Robustness of decompressor for TCP profile:
- Context Replication: check whether base context does exist before using it
- avoid assertion at decompressor with malformed TCP options:
- length of TCP options is not a multiple of 32-bit words
- large TCP options > 40 bytes
- handle length-changing generic TCP options
- kernel:
- fix 64-bit division
- fix nonnull warnings
- fix test application/script for Linux kernel module
- sniffer:
- handle packet timing so that context re-use works correctly
- detect layer-3 protocol from Ethernet protocol type
Q&A:
- fix compilation error when using gcc-7
- decrease code complexity
- fix some spelling mistakes detected by codespell
