* Replay r286410. Change KPI of how device drivers that provide wirelessGleb Smirnoff2015-08-271-0/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers.

* Remove IPX support.Gleb Smirnoff2014-03-141-56/+1
| | | | | | | | | | | | | | IPX was a network transport protocol in Novell's NetWare network operating system from late 80s and then 90s. The NetWare itself switched to TCP/IP as default transport in 1998. Later, in this century the Novell Open Enterprise Server became successor of Novell NetWare. The last release that claimed to still support IPX was OES 2 in 2007. Routing equipment vendors (e.g. Cisco) discontinued support for IPX in 2011. Thus, IPX won't be supported in FreeBSD 11.0-RELEASE. Notes: svn path=/head/; revision=263140

| | | | | | | | | | | | | | | | | | | | | Newly-configured systems should use $cloned_interfaces. - Call clone_{up,down}() and ifnet_rename() in rc.d/netif {start,stop}. ifnet_rename() now accepts an interface name list as its argument. - Add rc.d/netif clear. The "clear" subcommand is basically equivalent to "stop" but it does not call clone_down(). - Add "ifname:sticky" keyword into $cloned_interfaces. If :sticky is specified, the interface will not be destroyed in rc.d/netif stop. - Add cloned_interfaces_sticky={YES,NO}. This variable globally sets :sticky keyword above for all interfaces. The default value is NO. When cloned_interfaces_sticky=YES, :nosticky keyword can be used to override it on per interface basis. Notes: svn path=/head/; revision=253924

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an extended version of ipv4_addr_IF which supports both IPv4 and IPv6, and multiple range specifications. To avoid to generate too many addresses, the maximum number of the generated addresses is currently limited to 31. - Add $ifconfig_IF_aliases, which accepts multiple IP aliases in a variable. - ipv6_prefix_IF now supports !/64 prefix length. In addition to the old 64-bit format (2001:db8:1:1), a full 128-bit format like 2001:db8:1:1::/64 is supported. - Replace ifconfig command with $IFCONFIG_CMD variable to support a dry-run mode in the future. - Remove IP aliases before removing all of IPv4 addresses when doing "rc.d/netif down". - Add a DAD wait to network6_getladdr() because it is possible to fail to configure an EUI64 address when ipv6_prefix_IF is specified. A summary of the supported ifconfig_* variables is as follows: # IPv4 configuration. ifconfig_em0="inet 192.168.0.1" # IPv6 configuration. ifconfig_em0_ipv6="inet6 2001:db8::1/64" # IPv4 address range spec.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | (r225485). When setting an interface name to it, the following configurations will be enabled: 1. "no_radr" is set to all IPv6 interfaces automatically. 2. "-no_radr accept_rtadv" will be set only for $ipv6_cpe_wanif. This is done just before evaluating $ifconfig_IF_ipv6 in the rc.d scripts (this means you can manually supersede this configuration if necessary). 3. The node will add RA-sending routers to the default router list even if net.inet6.ip6.forwarding=1. This mode is added to conform to RFC 6204 (a router which connects the end-user network to a service provider network). To enable packet forwarding, you still need to set ipv6_gateway_enable=YES. Note that accepting router entries into the default router list when packet forwarding capability and a routing daemon are enabled can result in messing up the routing table. To minimize such unexpected behaviors, "no_radr" is set on all interfaces but $ipv6_cpe_wanif. Approved by: re (bz) Notes: svn path=/head/; revision=225521
