* 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

New kernel is binary compatible with old tools, since sizes of sockaddr_inarp and sockaddr_in match, and sa_family are filled with same value.

* Historically arp(8) did a route lookup for the entry it isGleb Smirnoff2012-04-021-4/+0
| | | | | | | | | | | | | | | | | | | | about to add, and failed if it exist and had invalid data link type. Later on, in r201282, this check morphed to other code, but message "proxy entry exists for non 802 device" still left, and now it is printed in a case if route prefix found is equal to current address being added. In other words, when we are trying to add ARP entry for a network address. The message is absolutely unrelated and disappointing in this case. I don't see anything bad with setting ARP entries for network addresses. While useless in usual network, in a /31 RFC3021 it may be necessary. This, remove this code.

* The proxy arp entries could not be added into the system over theQing Li2009-12-301-29/+35
| | | | | | | | | | | | | | | | | | | | | IFF_POINTOPOINT link types. The reason was due to the routing entry returned from the kernel covering the remote end is of an interface type that does not support ARP. This patch fixes this problem by providing a hint to the kernel routing code, which indicates the prefix route instead of the PPP host route should be returned to the caller. Since a host route to the local end point is also added into the routing table, and there could be multiple such instantiations due to multiple PPP links can be created with the same local end IP address, this patch also fixes the loopback route installation failure problem observed prior to this patch. The reference count of loopback route to local end would be either incremented or decremented. The first instantiation would create the entry and the last removal would delete the route entry.
