* rtadvd: add multi pref64 supportPouria Mousavizadeh Tehrani2026-03-066-63/+158
| | | | | | | Add support for multi pref64 in rtadvd and rtadvctl Reviewed By: zlei, bz Differential Revision: https://reviews.freebsd.org/D54636
* rtadvd(8): support PREF64 (RFC 8781)Lexi Winter2024-05-233-0/+97
| | | | | | | | | | PREF64 allows a router to advertise the network's NAT64 prefix, allowing clients to auto-configure CLAT. This makes it possible to deploy IPv6-only or IPv6-mostly client access networks without the need for DNS64.

* Update the "flag" for draft-ietf-6man-ipv6only-flag.Bjoern A. Zeeb2018-11-032-3/+3
| | | | | | | | | Having the flag named "6" can possibly be a problem for configurations where parsing strings and numbers can produce ambivalent results. Rename the "6" flag to the "S"ix (or Silence-IPv4) flag. Notes: svn path=/head/; revision=340098
* Initial implementation of draft-ietf-6man-ipv6only-flag.Bjoern A. Zeeb2018-10-304-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change defines the RA "6" (IPv6-Only) flag which routers may advertise, kernel logic to check if all routers on a link have the flag set and accordingly update a per-interface flag. If all routers agree that it is an IPv6-only link, ether_output_frame(), based on the interface flag, will filter out all ETHERTYPE_IP/ARP frames, drop them, and return EAFNOSUPPORT to upper layers. The change also updates ndp to show the "6" flag, ifconfig to display the IPV6_ONLY nd6 flag if set, and rtadvd to allow announcing the flag. Further changes to tcpdump (contrib code) are availble and will be upstreamed. Tested the code (slightly earlier version) with 2 FreeBSD IPv6 routers, a FreeBSD laptop on ethernet as well as wifi, and with Win10 and OSX clients (which did not fall over with the "6" flag set but not understood). We may also want to (a) implement and RX filter, and (b) over time enahnce user space to, say, stop dhclient from running when the interface flag is set. Also we might want to start IPv6 before IPv4 in the future. All the code is hidden under the EXPERIMENTAL option and not compiled by default as the draft is a work-in-progress and we cannot rely on the fact that IANA will assign the bits as requested by the draft and hence they may change. Dear 6man, you have running code. Discussed with: Bob Hinden, Brian E Carpenter Notes: svn path=/head/; revision=339929

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-277-2/+16
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* rtadvd(8): Fix a typo in full msg receive logicConrad Meyer2016-05-121-6/+6
| | | | | | | | | | | | | | | | | | | | | | Check against the size of the struct, not the pointer. Previously, a message with a cm_len between 9 and 23 (inclusive) could cause int msglen to underflow and read(2) to be invoked with msglen size (implicitly cast to signed), overrunning the caller-provided buffer. All users of cm_recv() supply a stack buffer. On the other hand, the rtadvd control socket appears to only be writable by the owner, who is probably root. While here, correct some types to be size_t or ssize_t.
