This patch set includes fixes to bring the segment routing
implementation into conformance with the latest version of the
draft (draft-ietf-6man-segment-routing-header-19). Also, segment
routing receive function calls ip6_parse to properly parse TLVs
in parsing loop.
Changes include:
- Update TLV macro definitions. Mark obsoleted TLVs as such, add
definitions for PAD1 and PADN
- Mark obsoleted flags as such
- Implement parsing loop in sr_has_hmac to find HMAC TLV without
relying on obsoleted flag
- Parameterize ip6_parse_tlv so that it can be used for parsing
segment routing TLVs
- Add sysctls for segment routing TLV parsing limits
- Segment routing receive functions call ip6_parse_tlv
Tom Herbert (5):
seg6: Fix TLV definitions
seg6: Obsolete unused SRH flags
ipv6: Paramterize TLV parsing
seg6: Add sysctl limits for segment routing header
seg6: Leverage ip6_parse_tlv
