* Ensure consistent error messages from ifconfig(8).Hans Petter Selasky2020-11-261-2/+1
| | | | | | | | | | | | | | | | | | | If multiple threads are invoking "ifconfig XXX create" a race may occur which can lead to two different error messages for the same error. a) ifconfig: SIOCIFCREATE2: File exists b) ifconfig: interface XXX already exists This patch ensures ifconfig prints the same error code for the same case.

* Add support for stacked VLANs (IEEE 802.1ad, AKA Q-in-Q).Alexander V. Chernikov2020-10-211-1/+77
| | | | | | | | | | | | | | | | | | | | | 802.1ad interfaces are created with ifconfig using the "vlanproto" parameter. Eg., the following creates a 802.1Q VLAN (id #42) over a 802.1ad S-VLAN (id #5) over a physical Ethernet interface (em0). ifconfig vlan5 create vlandev em0 vlan 5 vlanproto 802.1ad up ifconfig vlan42 create vlandev vlan5 vlan 42 inet 10.5.42.1/24 VLAN_MTU, VLAN_HWCSUM and VLAN_TSO capabilities should be properly supported. VLAN_HWTAGGING is only partially supported, as there is currently no IFCAP_VLAN_* denoting the possibility to set the VLAN EtherType to anything else than 0x8100 (802.1ad uses 0x88A8).

* spdx: initial adoption of licensing ID tags.Pedro F. Giffuni2017-11-181-1/+3
| | | | | | | | | | | | | | | | | | | | 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. Initially, only tag files that use BSD 4-Clause "Original" license. RelNotes: yes Differential Revision: https://reviews.freebsd.org/D13133 Notes: svn path=/head/; revision=325966
* Add support to priority code point (PCP) that is an 3-bit fieldMarcelo Araujo2016-06-061-6/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | which refers to IEEE 802.1p class of service and maps to the frame priority level. Values in order of priority are: 1 (Background (lowest)), 0 (Best effort (default)), 2 (Excellent effort), 3 (Critical applications), 4 (Video, < 100ms latency), 5 (Video, < 10ms latency), 6 (Internetwork control) and 7 (Network control (highest)). Example of usage: root# ifconfig em0.1 create root# ifconfig em0.1 vlanpcp 3 Note: The review D801 includes the pf(4) part, but as discussed with kristof, we won't commit the pf(4) bits for now.

| | | | | | | | | | | | | | | | | | as both have been read from the command line. Still use the callback, but this time only to verify that both vlan and vlandev have been found on the command line. This should allow for control over the relative order of processing parameters, which is needed to satisfy some caveats of the if_vlan driver. E.g., MTU cannot be changed on a vlan interface until it's attached to its parent. PR: bin/94028 Reviewed by: ru MFC after: 3 days Notes: svn path=/head/; revision=156498

* Fix special status reporting. Prior to the reorg there wasSam Leffler2004-12-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | special-purpose code to display status for an interface for state that was not address-oriented. This status reporting was merged in to the address-oriented status reporting but did not work for link address reporting (as discovered with fwip interfaces). Correct this mis-merge and eliminate the bogus kludge that was used for link-level address reporting. o add an af_other_status method for an address family for reporting status of things like media, vlan, etc. o call the af_other_status methods after reporting address status for an interface o special-case link address status; when reporting all status for an interface invoke it specially prior to reporting af_other_status methods (since it requires the sockaddr_dl that is passed in to status separately from the rtmsg address state) o correct the calling convention for link address status; don't cast types, construct the proper parameter This fixes ifconfig on fwip interfaces.

* Overhaul to cleanup some of the tangled logic that's grown over the years.Sam Leffler2004-12-081-5/+32
| | | | | | | | | | | | | | | | | | | | | | | o break per-address family support out into separate files o modularize per-address family and functional operations using a registration mechanism; this permits configuration according to which files you include (but beware that order of the files is important to insure backwards compatibility) o many cleanups to eliminate incestuous behaviour, global variables, and poor coding practices (still much more to fix) The original motivation of this work was to support dynamic addition of functionality based on the interface so we can eliminate the various little control programs and so that vendors can distribute ifconfig plugins that support their in-kernel code. That work is still to be completed. o Update 802.11 support for all the new net80211 functionality; some of these operations (e.g. list *) may be better suited in a different program Notes: svn path=/head/; revision=138593
