Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Replay r286410. Change KPI of how device drivers that provide wireless 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.

Begin plumbing ieee80211_rx_stats through the receive path. Smart NICs with firmware (eg wpi, iwn, the new atheros parts, the intel 7260 series, etc) support doing a lot of things in firmware. This includes but isn't limited to things like scanning, sending probe requests and receiving probe responses. However, net80211 doesn't know about any of this - it still drives the whole scan/probe infrastructure itself. In order to move towards suppoting smart NICs, the receive path needs to know about the channel/details for each received packet. In at least the iwn and 7260 firmware (and I believe wpi, but I haven't tried it yet) it will do the scanning, power-save and off-channel buffering for you - all you need to do is handle receiving beacons and probe responses on channels that aren't what you're currently on. However the whole receive path is peppered with ic->ic_curchan and manual scan/powersave handling. The beacon parsing code also checks ic->ic_curchan to determine if the received beacon is on the correct channel or not.[1] So: * add freq/ieee values to ieee80211_rx_stats; * change ieee80211_parse_beacon() to accept the 'current' channel as an argument; * modify the iv_input() and iv_recv_mgmt() methods to include the rx_stats; * add a new method - ieee80211_lookup_channel_rxstats() - that looks up a channel based on the contents of ieee80211_rx_stats; * if it exists, use it in the mgmt path to switch the current channel (which still defaults to ic->ic_curchan) over to something determined by rx_stats. This is enough to kick-start scan offload support in the Intel 7260 driver that Rui/I are working on. It also is a good start for scan offload support for a handful of existing NICs (wpi, iwn, some USB parts) and it'll very likely dramatically improve stability/performance there. It's not the whole thing - notably, we don't need to do powersave, we should not scan all channels, and we should leave probe request sending to the firmware and not do it ourselves. But, this allows for continued development on the above features whilst actually having a somewhat working NIC. TODO: * Finish tidying up how the net80211 input path works. Right now ieee80211_input / ieee80211_input_all act as the top-level that everything feeds into; it should change so the MIMO input routines are those and the legacy routines are phased out. * The band selection should be done by the driver, not by the net80211 layer. * ieee80211_lookup_channel_rxstats() only determines 11b or 11g channels for now - this is enough for scanning, but not 100% true in all cases. If we ever need to handle off-channel scan support for things like static-40MHz or static-80MHz, or turbo-G, or half/quarter rates, then we should extend this. [1] This is a side effect of frequency-hopping and CCK modes - you can receive beacons when you think you're on a different channel. In particular, CCK (which is used by the low 11b rates, eg beacons!) is decodable from adjacent channels - just at a low SNR. FH is a side effect of having the hardware/firmware do the frequency hopping - it may pick up beacons transmitted from other FH networks that are in a different phase of hopping frequencies.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Replay r286410. Change KPI of how device drivers that provide wireless 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.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Replay r286410. Change KPI of how device drivers that provide wireless 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.

Replay r286410. Change KPI of how device drivers that provide wireless 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. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.)

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it).

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.

MFp4 changes to fix locking issues and correct reference count handling of station entries in hostap mode: Input path: o driver is now expected to find the node associated with the sender of a received frame; use ic_bss if none is located o driver passes the (referenced) node into ieee80211_input for use within the wlan module and is responsible for cleaning up on return o the antenna state is no longer passed up with each frame; this is now considered driver-private state and drivers are responsible for keeping it in the driver-private part of a node Output path: Revamp output path for management frames to eliminate redundant locking that causes problems and to correct reference counting bogosity that occurs when stations are timed out due to inactivity (in AP mode). On output the refcnt'd node is stashed in the pkthdr's recvif field (yech) and retrieved by the driver. This eliminates an unref/ref scenario and related node table unlock/lock due to the driver looking up the node. This is particularly important when stations are timed out as this causes a lock order reversal that can result in a deadlock. As a byproduct we also reduce the overhead for sending management frames (minimal). Additional fallout from this is a change to ieee80211_encap to return a refcn't node for tieing to the outbound frame. Node refcnts are not reclaimed until after a frame is completely processed (e.g. in the tx interrupt handler). This is especially important for timed out stations as this deref will be the final one causing the node entry to be reclaimed. Additional semi-related changes: o replace m_copym use with m_copypacket (optimization) o add assert to verify ic_bss is never free'd during normal operation o add comments explaining calling conventions by drivers for frames going in each direction o remove extraneous code that "cannot be executed" (e.g. because pointers may never be null)

Begin plumbing ieee80211_rx_stats through the receive path. Smart NICs with firmware (eg wpi, iwn, the new atheros parts, the intel 7260 series, etc) support doing a lot of things in firmware. This includes but isn't limited to things like scanning, sending probe requests and receiving probe responses. However, net80211 doesn't know about any of this - it still drives the whole scan/probe infrastructure itself. In order to move towards suppoting smart NICs, the receive path needs to know about the channel/details for each received packet. In at least the iwn and 7260 firmware (and I believe wpi, but I haven't tried it yet) it will do the scanning, power-save and off-channel buffering for you - all you need to do is handle receiving beacons and probe responses on channels that aren't what you're currently on. However the whole receive path is peppered with ic->ic_curchan and manual scan/powersave handling. The beacon parsing code also checks ic->ic_curchan to determine if the received beacon is on the correct channel or not.[1] So: * add freq/ieee values to ieee80211_rx_stats; * change ieee80211_parse_beacon() to accept the 'current' channel as an argument; * modify the iv_input() and iv_recv_mgmt() methods to include the rx_stats; * add a new method - ieee80211_lookup_channel_rxstats() - that looks up a channel based on the contents of ieee80211_rx_stats; * if it exists, use it in the mgmt path to switch the current channel (which still defaults to ic->ic_curchan) over to something determined by rx_stats. This is enough to kick-start scan offload support in the Intel 7260 driver that Rui/I are working on. It also is a good start for scan offload support for a handful of existing NICs (wpi, iwn, some USB parts) and it'll very likely dramatically improve stability/performance there. It's not the whole thing - notably, we don't need to do powersave, we should not scan all channels, and we should leave probe request sending to the firmware and not do it ourselves. But, this allows for continued development on the above features whilst actually having a somewhat working NIC. TODO: * Finish tidying up how the net80211 input path works. Right now ieee80211_input / ieee80211_input_all act as the top-level that everything feeds into; it should change so the MIMO input routines are those and the legacy routines are phased out. * The band selection should be done by the driver, not by the net80211 layer. * ieee80211_lookup_channel_rxstats() only determines 11b or 11g channels for now - this is enough for scanning, but not 100% true in all cases. If we ever need to handle off-channel scan support for things like static-40MHz or static-80MHz, or turbo-G, or half/quarter rates, then we should extend this. [1] This is a side effect of frequency-hopping and CCK modes - you can receive beacons when you think you're on a different channel. In particular, CCK (which is used by the low 11b rates, eg beacons!) is decodable from adjacent channels - just at a low SNR. FH is a side effect of having the hardware/firmware do the frequency hopping - it may pick up beacons transmitted from other FH networks that are in a different phase of hopping frequencies.

Begin plumbing ieee80211_rx_stats through the receive path. Smart NICs with firmware (eg wpi, iwn, the new atheros parts, the intel 7260 series, etc) support doing a lot of things in firmware. This includes but isn't limited to things like scanning, sending probe requests and receiving probe responses. However, net80211 doesn't know about any of this - it still drives the whole scan/probe infrastructure itself. In order to move towards suppoting smart NICs, the receive path needs to know about the channel/details for each received packet. In at least the iwn and 7260 firmware (and I believe wpi, but I haven't tried it yet) it will do the scanning, power-save and off-channel buffering for you - all you need to do is handle receiving beacons and probe responses on channels that aren't what you're currently on. However the whole receive path is peppered with ic->ic_curchan and manual scan/powersave handling. The beacon parsing code also checks ic->ic_curchan to determine if the received beacon is on the correct channel or not.[1] So: * add freq/ieee values to ieee80211_rx_stats; * change ieee80211_parse_beacon() to accept the 'current' channel as an argument; * modify the iv_input() and iv_recv_mgmt() methods to include the rx_stats; * add a new method - ieee80211_lookup_channel_rxstats() - that looks up a channel based on the contents of ieee80211_rx_stats; * if it exists, use it in the mgmt path to switch the current channel (which still defaults to ic->ic_curchan) over to something determined by rx_stats. This is enough to kick-start scan offload support in the Intel 7260 driver that Rui/I are working on. It also is a good start for scan offload support for a handful of existing NICs (wpi, iwn, some USB parts) and it'll very likely dramatically improve stability/performance there. It's not the whole thing - notably, we don't need to do powersave, we should not scan all channels, and we should leave probe request sending to the firmware and not do it ourselves. But, this allows for continued development on the above features whilst actually having a somewhat working NIC. TODO: * Finish tidying up how the net80211 input path works. Right now ieee80211_input / ieee80211_input_all act as the top-level that everything feeds into; it should change so the MIMO input routines are those and the legacy routines are phased out. * The band selection should be done by the driver, not by the net80211 layer. * ieee80211_lookup_channel_rxstats() only determines 11b or 11g channels for now - this is enough for scanning, but not 100% true in all cases. If we ever need to handle off-channel scan support for things like static-40MHz or static-80MHz, or turbo-G, or half/quarter rates, then we should extend this. [1] This is a side effect of frequency-hopping and CCK modes - you can receive beacons when you think you're on a different channel. In particular, CCK (which is used by the low 11b rates, eg beacons!) is decodable from adjacent channels - just at a low SNR. FH is a side effect of having the hardware/firmware do the frequency hopping - it may pick up beacons transmitted from other FH networks that are in a different phase of hopping frequencies.

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.

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.

Replay r286410. Change KPI of how device drivers that provide wireless 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.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

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.

Update 802.11 wireless support: o major overhaul of the way channels are handled: channels are now fully enumerated and uniquely identify the operating characteristics; these changes are visible to user applications which require changes o make scanning support independent of the state machine to enable background scanning and roaming o move scanning support into loadable modules based on the operating mode to enable different policies and reduce the memory footprint on systems w/ constrained resources o add background scanning in station mode (no support for adhoc/ibss mode yet) o significantly speedup sta mode scanning with a variety of techniques o add roaming support when background scanning is supported; for now we use a simple algorithm to trigger a roam: we threshold the rssi and tx rate, if either drops too low we try to roam to a new ap o add tx fragmentation support o add first cut at 802.11n support: this code works with forthcoming drivers but is incomplete; it's included now to establish a baseline for other drivers to be developed and for user applications o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates prepending mbufs for traffic generated locally o add support for Atheros protocol extensions; mainly the fast frames encapsulation (note this can be used with any card that can tx+rx large frames correctly) o add sta support for ap's that beacon both WPA1+2 support o change all data types from bsd-style to posix-style o propagate noise floor data from drivers to net80211 and on to user apps o correct various issues in the sta mode state machine related to handling authentication and association failures o enable the addition of sta mode power save support for drivers that need net80211 support (not in this commit) o remove old WI compatibility ioctls (wicontrol is officially dead) o change the data structures returned for get sta info and get scan results so future additions will not break user apps o fixed tx rate is now maintained internally as an ieee rate and not an index into the rate set; this needs to be extended to deal with multi-mode operation o add extended channel specifications to radiotap to enable 11n sniffing Drivers: o ath: add support for bg scanning, tx fragmentation, fast frames, dynamic turbo (lightly tested), 11n (sniffing only and needs new hal) o awi: compile tested only o ndis: lightly tested o ipw: lightly tested o iwi: add support for bg scanning (well tested but may have some rough edges) o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data o wi: lightly tested This work is based on contributions by Atheros, kmacy, sephe, thompsa, mlaier, kevlo, and others.

MFp4 changes to fix locking issues and correct reference count handling of station entries in hostap mode: Input path: o driver is now expected to find the node associated with the sender of a received frame; use ic_bss if none is located o driver passes the (referenced) node into ieee80211_input for use within the wlan module and is responsible for cleaning up on return o the antenna state is no longer passed up with each frame; this is now considered driver-private state and drivers are responsible for keeping it in the driver-private part of a node Output path: Revamp output path for management frames to eliminate redundant locking that causes problems and to correct reference counting bogosity that occurs when stations are timed out due to inactivity (in AP mode). On output the refcnt'd node is stashed in the pkthdr's recvif field (yech) and retrieved by the driver. This eliminates an unref/ref scenario and related node table unlock/lock due to the driver looking up the node. This is particularly important when stations are timed out as this causes a lock order reversal that can result in a deadlock. As a byproduct we also reduce the overhead for sending management frames (minimal). Additional fallout from this is a change to ieee80211_encap to return a refcn't node for tieing to the outbound frame. Node refcnts are not reclaimed until after a frame is completely processed (e.g. in the tx interrupt handler). This is especially important for timed out stations as this deref will be the final one causing the node entry to be reclaimed. Additional semi-related changes: o replace m_copym use with m_copypacket (optimization) o add assert to verify ic_bss is never free'd during normal operation o add comments explaining calling conventions by drivers for frames going in each direction o remove extraneous code that "cannot be executed" (e.g. because pointers may never be null)

This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly).

Replay r286410. Change KPI of how device drivers that provide wireless 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.

Replay r286410. Change KPI of how device drivers that provide wireless 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.

Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Replay r286410. Change KPI of how device drivers that provide wireless 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. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Replay r286410. Change KPI of how device drivers that provide wireless 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. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

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. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Add device driver support for the Lucent WaveLAN/IEEE 802.11 wireless network adapters. These are all PCMCIA devices (the ISA version is a PCMCIA to ISA bridge with a PCMCIA card plugged into it). Also add a wicontrol utility to read and write some of the card's parameters. Note: I do not have access to a WavePOINT access point, so I have only been able to test this driver in ad-hoc (point to point) mode. The wicontrol utility allows programming the desired service set name (SSID) and enabling BSS mode, but I can't tell for sure if it works (I know the card switches modes, but I can't verify that it joins a service set correctly). This driver was written using information gleaned from the Lucent HCF Light library, which is an API library designed to simplify driver development for devices based on the Lucent Hermes chip. Unfortunately, the HCF Light is missing certain features (like 802.11 frame encapsulation!) which are available only in the proprietary complete HCF code, which is not available to the public. This driver uses none of the HCF Light code: it's very ugly and contaminated by the GPL. IP and ARP packets are encapsulated as 802.11 frames, everything else is encapsulated as 802.3. (It would be easier to just get the Hermes programming manual, but that's not publically available either. For those who are wondering, the Linux WaveLAN/IEEE driver uses the proprietary HCF code, which is provided in object code form only. So much for supporting open source sofware.) Multicast filter support is implemented, however it appears that the filter doesn't work: programming in one IP mutlicast group enables them all.

Update 802.11 wireless support: o major overhaul of the way channels are handled: channels are now fully enumerated and uniquely identify the operating characteristics; these changes are visible to user applications which require changes o make scanning support independent of the state machine to enable background scanning and roaming o move scanning support into loadable modules based on the operating mode to enable different policies and reduce the memory footprint on systems w/ constrained resources o add background scanning in station mode (no support for adhoc/ibss mode yet) o significantly speedup sta mode scanning with a variety of techniques o add roaming support when background scanning is supported; for now we use a simple algorithm to trigger a roam: we threshold the rssi and tx rate, if either drops too low we try to roam to a new ap o add tx fragmentation support o add first cut at 802.11n support: this code works with forthcoming drivers but is incomplete; it's included now to establish a baseline for other drivers to be developed and for user applications o adjust max_linkhdr et. al. to reflect 802.11 requirements; this eliminates prepending mbufs for traffic generated locally o add support for Atheros protocol extensions; mainly the fast frames encapsulation (note this can be used with any card that can tx+rx large frames correctly) o add sta support for ap's that beacon both WPA1+2 support o change all data types from bsd-style to posix-style o propagate noise floor data from drivers to net80211 and on to user apps o correct various issues in the sta mode state machine related to handling authentication and association failures o enable the addition of sta mode power save support for drivers that need net80211 support (not in this commit) o remove old WI compatibility ioctls (wicontrol is officially dead) o change the data structures returned for get sta info and get scan results so future additions will not break user apps o fixed tx rate is now maintained internally as an ieee rate and not an index into the rate set; this needs to be extended to deal with multi-mode operation o add extended channel specifications to radiotap to enable 11n sniffing Drivers: o ath: add support for bg scanning, tx fragmentation, fast frames, dynamic turbo (lightly tested), 11n (sniffing only and needs new hal) o awi: compile tested only o ndis: lightly tested o ipw: lightly tested o iwi: add support for bg scanning (well tested but may have some rough edges) o ral, ural, rum: add suppoort for bg scanning, calibrate rssi data o wi: lightly tested This work is based on contributions by Atheros, kmacy, sephe, thompsa, mlaier, kevlo, and others. Much of the scanning work was supported by Atheros. The 11n work was supported by Marvell.
