Subject: [PATCH v6 net-next 0/9] ipv6: Extension header infrastructure
Date: Fri, 20 Dec 2019 15:38:35 -0800 [thread overview]
Message-ID: <1576885124-14576-1-git-send-email-tom@herbertland.com> (raw)
This patchset improves the IPv6 extension header infrastructure
to make extension headers more usable and scalable.
- Reorganize extension header files to separate out common
API components
- Create common TLV handler that will can be used in other use
cases (e.g. segment routing TLVs, UDP options)
- Allow registration of TLV handlers
- Elaborate on the TLV tables to include more characteristics
- Add a netlink interface to set TLV parameters (such as
alignment requirements, authorization to send, etc.)
- Enhance validation of TLVs being sent. Validation is strict
(unless overridden by admin) following the sending clause
of the robustness principle
- Allow non-privileged users to set Hop-by-Hop and Destination
Options if authorized by the admin
v2:
- Fix build errors from missing include file.
v3:
- Fix kbuild issue for ipv6_opt_hdr declared inside parameter list
in ipeh.h
v4:
- Resubmit
v5:
- Fix reverse christmas tree issue
v6:
- Address comments from Simon Horman
- Remove new EXTHDRS Kconfig symbol, just use IPV6 for now
- Split out introduction of parse_error for TLV parsing loop into its
own patch
- Fix drop counters in HBH and destination options processing
- Add extack error messages in netlink code
- Added range of permissions in include/uapi/linux/ipeh.h
- Check that min data length is <= max data length when setting
TLV attributes
Tom Herbert (9):
ipeh: Fix destopts and hopopts counters on drop
ipeh: Create exthdrs_options.c and ipeh.h
ipeh: Move generic EH functions to exthdrs_common.c
ipeh: Generic TLV parser
ipeh: Add callback to ipeh_parse_tlv to handle errors
ip6tlvs: Registration of TLV handlers and parameters
ip6tlvs: Add TX parameters
ip6tlvs: Add netlink interface
ip6tlvs: Validation of TX Destination and Hop-by-Hop options
