f3f28e69a7 Adjust the VLAN section of the ifconfig(8) man page to better reflect
reality:

1. Only 12-bit VLAN Identifiers, not full 16-bit VLAN tags can be set using
   ifconfig vlan.

2. When we mean VLAN Identifiers, spell it that way, rather than as VLAN tag.

5f02482794 Rename ifcarp.c to carp.c 2011-12-16 14:30:58 +00:00

92ed4e1a24 Since size of struct in_aliasreq has just been changed in r228571,
and thus ifconfig(8) needs recompile, it is a good chance to make
parameter checks on SIOCAIFADDR arguments more strict.

08b68b0e4c A major overhaul of the CARP implementation. The ip_carp.c was started
from scratch, copying needed functionality from the old implemenation
on demand, with a thorough review of all code. The main change is that
interface layer has been removed from the CARP. Now redundant addresses
are configured exactly on the interfaces, they run on.

The CARP configuration itself is, as before, configured and read via
SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or
SIOCAIFADDR_IN6 may now be configured to a particular virtual host id,
which makes the prefix redundant.

ifconfig(8) semantics has been changed too: now one doesn't need
to clone carpXX interface, he/she should directly configure a vhid
on a Ethernet interface.

To supply vhid data from the kernel to an application the getifaddrs(8)
function had been changed to pass ifam_data with each address. [1]

The new implementation definitely closes all PRs related to carp(4)
being an interface, and may close several others. It also allows
to run a single redundant IP per interface.

Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for
idea on using ifam_data and for several rounds of reviewing!

2168aaa506 This patch removes a check in ifconfig which disables HT/40 channels
on frequency bands with DFS. All Atheros chipsets >= AR9001 support
radar event detection on HT40 extension channels.

This should be a chipset specific item rather than enforced in the
regulatory domain database.

In addition, it's irrelevant for STA mode, as the radar detection is
done by the access point, not the STA.

e7fa8d0ada - Accept Router Advertisement messages even when net.inet6.ip6.forwarding=1.
- A new per-interface knob IFF_ND6_NO_RADR and sysctl IPV6CTL_NO_RADR.
  This controls if accepting a route in an RA message as the default route.
  The default value for each interface can be set by net.inet6.ip6.no_radr.
  The system wide default value is 0.

- A new sysctl: net.inet6.ip6.norbit_raif.  This controls if setting R-bit in
  NA on RA accepting interfaces.  The default is 0 (R-bit is set based on
  net.inet6.ip6.forwarding).

Background:

 IPv6 host/router model suggests a router sends an RA and a host accepts it for
 router discovery.  Because of that, KAME implementation does not allow
 accepting RAs when net.inet6.ip6.forwarding=1.  Accepting RAs on a router can
 make the routing table confused since it can change the default router
 unintentionally.

 However, in practice there are cases where we cannot distinguish a host from
 a router clearly.  For example, a customer edge router often works as a host
 against the ISP, and as a router against the LAN at the same time.  Another
 example is a complex network configurations like an L2TP tunnel for IPv6
 connection to Internet over an Ethernet link with another native IPv6 subnet.
 In this case, the physical interface for the native IPv6 subnet works as a
 host, and the pseudo-interface for L2TP works as the default IP forwarding
 route.

Problem:

 Disabling processing RA messages when net.inet6.ip6.forwarding=1 and
 accepting them when net.inet6.ip6.forward=0 cause the following practical
 issues:

 - A router cannot perform SLAAC.  It becomes a problem if a box has
   multiple interfaces and you want to use SLAAC on some of them, for
   example.  A customer edge router for IPv6 Internet access service
   using an IPv6-over-IPv6 tunnel sometimes needs SLAAC on the
   physical interface for administration purpose; updating firmware
   and so on (link-local addresses can be used there, but GUAs by
   SLAAC are often used for scalability).

 - When a host has multiple IPv6 interfaces and it receives multiple RAs on
   them, controlling the default route is difficult.  Router preferences
   defined in RFC 4191 works only when the routers on the links are
   under your control.

Details of Implementation Changes:

 Router Advertisement messages will be accepted even when
 net.inet6.ip6.forwarding=1.  More precisely, the conditions are as
 follow:

 (ACCEPT_RTADV && !NO_RADR && !ip6.forwarding)
	=> Normal RA processing on that interface. (as IPv6 host)

 (ACCEPT_RTADV && (NO_RADR || ip6.forwarding))
	=> Accept RA but add the router to the defroute list with
	   rtlifetime=0 unconditionally.  This effectively prevents
	   from setting the received router address as the box's
	   default route.

 (!ACCEPT_RTADV)
	=> No RA processing on that interface.

 ACCEPT_RTADV and NO_RADR are per-interface knob.  In short, all interface
 are classified as "RA-accepting" or not.  An RA-accepting interface always
 processes RA messages regardless of ip6.forwarding.  The difference caused by
 NO_RADR or ip6.forwarding is whether the RA source address is considered as
 the default router or not.

 R-bit in NA on the RA accepting interfaces is set based on
 net.inet6.ip6.forwarding.  While RFC 6204 W-1 rule (for CPE case) suggests
 a router should disable the R-bit completely even when the box has
 net.inet6.ip6.forwarding=1, I believe there is no technical reason with
 doing so.  This behavior can be set by a new sysctl net.inet6.ip6.norbit_raif
 (the default is 0).

Usage:

 # ifconfig fxp0 inet6 accept_rtadv
	=> accept RA on fxp0
 # ifconfig fxp0 inet6 accept_rtadv no_radr
	=> accept RA on fxp0 but ignore default route information in it.
 # sysctl net.inet6.ip6.norbit_no_radr=1
	=> R-bit in NAs on RA accepting interfaces will always be set to 0.

5af3fa9a5f Conditionally compile in the af_inet and af_inet6, af_nd6 modules.
If compiled in for dual-stack use, test with feature_present(3)
to see if we should register the IPv4/IPv6 address family related
options.

In case there is no "inet" support we would love to go with the
usage() and make the address family mandatory (as it is for anything
but inet in theory).  Unfortunately people are used to
  ifconfig IF up/down
etc. as well, so use a fallback of "link".  Adjust the man page
to reflect these minor details.

Improve error handling printing a warning in addition to the usage
telling that we do not know the given address family in two places.

6f135a7584 When setting media always and not just in case of switching to IFM_AUTO
clear the options of the current media, i.e. only inherit the instance,
which matches what NetBSD does. Without this it's really non-intuitive
that the following sequence:
	ifconfig bge0 media 1000baseT mediaopt full-duplex
	ifconfig bge0 media 100baseTX
results in 100baseTX full-duplex to be set or that:
	ifconfig bge0 media autoselect mediaopt flowcontrol
	ifconfig bge0 media 1000baseT mediaopt full-duplex
tries to set 1000baseT full-duplex with flowcontrol, which isn't suported
und thus fails while the following:
	ifconfig re0 media 1000baseT mediaopt flowcontrol,full-duplex
	ifconfig re0 media autoselect
just switches to autoselection without flowcontrol.

90e0ec14c1 Fix the 'scan hang' issue.
When requesting a scan and one is already in progess, e.g. while in scan
state, we happily wait for a scan done notification. Though, this
notification might never be sent, e.g. if we are trying to find a network
to associate to and there is none. Instead of always waiting for a
notification just do so if a new scan has been started. For both cases the
scan cache is used to report available networks even if the content might
not be fresh.

a272741053 When doing a scan while being associated it is possible that the scan
is deferred for the time it takes to flush the TX queue. This work being
done the scan then is continued, but only if it is marked to do so. As
the 'ifconfig scan' request is meant to be used after the interface is
brought up, request a background scan by default. This behaviour is
already documented in manual page.

interface considers that it hits a fatal error, and will not copyout

The previous implementation of the SIOCGIFDESCR ioctl intends to
feed the buffer length back to userland.  However, if we return

trap into an infinite loop.
