* ndp(8): increase buffer size in rtsock modeBoris Lytochkin2024-02-191-0/+6
| | | | | | | | | | | | | | On a router with many connected devices (~10k+) `ndp -an` can fail with ENOMEM because of some additional NDP records were added between sysctl() buffer size estimate and data fetch calls. Allocate more space based on size estimate: 1/64 (~2%) of additional space, but not less that 4 m_rtmsg structures.

* ndp: improve -c and -d handling in ndp_netlinkR. Christian McDonald2023-10-233-9/+14
| | | | | | | | | | | | | | | This patch restores/fixes some of the behavior present in pre-netlink ndp(8). 1. Deleting a local address now correctly returns EPERM (instead of ENOENT) 2. ndp -c no longer dumps the entire table while complaining about local addresses 3. Return exit code when deleting entry (e.g. trying ndp -d on a local address is an error) Reviewed by: kp Sponsored by: Rubicon Communications, LLC ("Netgate") Differential Revision: https://reviews.freebsd.org/D42316

* netlink: cope with growing requestsKristof Provost2023-10-171-6/+6
| | | | | | | | | | | | | If a request ends up growing beyong the initially allocated space the netlink functions (such as snl_add_msg_attr_u32()) will allocate a new buffer. This invalidates the header pointer we can have received from snl_create_msg_request(). Always use the hdr returned by snl_finalize_msg().

* Fix arp/ndp deletion broken by 2fe5a79425c7.Alexander V. Chernikov2021-02-191-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Changes in the 2fe5a79425c7 moved dst sockaddr masking from the routing control plane to the rtsock code. It broke arp/ndp deletion. It turns out, arp/ndp perform RTM_GET request first to get an interface index necessary for the deletion. Then they simply stamp the reply with RTF_LLDATA and set the command to RTM_DELETE. As a result, kernel receives request with non-empty RTA_NETMASK and clears RTA_DST host bits before passing the message to the lla code. De facto, the only needed bits are RTA_DST, RTA_GATEWAY and the subset of rtm_flags. With that in mind, fix the interace by clearing RTA_NETMASK for every messages with RTF_LLDATA. While here, cleanup arp/ndp code a bit. MFC after: 1 day Reviewed by: gnn Differential Revision: https://reviews.freebsd.org/D28804
* Update the "flag" for draft-ietf-6man-ipv6only-flag.Bjoern A. Zeeb2018-11-031-1/+1
| | | | | | | | | 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. Zeeb2018-10-302-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

| | | | | | | | | | | | | | | | | | Before the change, things like lle state were queried via SIOCGNBRINFO_IN6 by ndp(8) for _each_ lle entry in dump. This ioctl was added in 1999, probably to avoid touching rtsock code. This change maps SIOCGNBRINFO_IN6 data to standard rtsock dump the following way: expire (already) maps to rtm_rmx.rmx_expire isrouter -> rtm_flags & RTF_GATEWAY asked -> rtm_rmx.rmx_pksent state -> rtm_rmx.rmx_state (maps to rmx_weight via define) Reviewed by: ae Notes: svn path=/head/; revision=292333
