sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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.

net80211 rate control framework (net80211 ratectl). This framework allows drivers to abstract the rate control algorithm and just feed the framework with the usable parameters. The rate control framework will now deal with passing the parameters to the selected algorithm. Right now we have AMRR (the default) and RSSADAPT but there's no way to select one with ifconfig, yet. The objective is to have more rate control algorithms in the net80211 stack so all drivers[0] can use it. Ideally, we'll have the well-known sample rate control algorithm in the net80211 at some point so all drivers can use it (not just ath). [0] all drivers that do rate control in software, that is.

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations. To test bwn(4) with bhnd(4), place the following lines in loader.conf(5): hw.bwn_pci.preferred="1" if_bwn_pci_load="YES bwn_v4_ucode_load="YES" bwn_v4_lp_ucode_load="YES" To verify that bwn(4) is using bhnd(4), you can check dmesg: bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0 ... or devinfo(8): pcib2 pci2 bwn_pci0 bhndb0 bhnd0 bwn0 ... bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently supported by bwn(4), including: - BCM4312 - BCM4318 - BCM4321 With minimal changes to the DMA code (not included in this commit), I was also able to test support for newer BCMA devices by bringing up basic working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets: - BCM43224 - BCM43225 Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation & Plausible Labs Differential Revision: https://reviews.freebsd.org/D13041

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.

net80211: ieee80211_ratectl*: switch to reusable KPI Replace various void * / int argument combinations with common structures: - ieee80211_ratectl_tx_status for *_tx_complete(); - ieee80211_ratectl_tx_stats for *_tx_update(); While here, improve amrr_tx_update() for a bit: 1. In case, if receiver is not known (typical for Ralink USB drivers), refresh Tx rate for all nodes on the interface. 2. There was a misuse: - otus(4) sends non-decreasing counters (as originally intended); - but ural(4), rum(4) and run(4) are using 'read & clear' registers to obtain statistics for some period of time (and those 'last period' values are used as arguments for tx_update()). If arguments are not big enough, they are just discarded after the next call. Fix: move counting into *_tx_update() (now otus(4) will zero out all node counters after every tx_update() call) Tested with: - Intel 3945BG (wpi(4)), STA mode. - WUSB54GC (rum(4)), STA / HOSTAP mode. - RTL8188EU (urtwn(4)), STA mode.

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations.

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent.

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.

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.

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.

Fix a possible mbuf double free in bwn_dma_tx_start(). If bus_dmamap_load_mbuf() fails following a defrag, the caller of bwn_dma_tx_start() would free the original mbuf after m_defrag() had already done so. Fix this by returning the defragged mbuf to the caller instead. Update bwn_pio_tx_start() similarly for consistency.

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations.

[bwn] Enable PHY-LP 5GHz support for the one NIC I have tested it on so far. After perusing the PHY-LP code (don't ask why; honest) I discovered that it /has/ 5GHz support - but it's not ever used. I found one NIC - a BCM4312 w/ pci id 0x4315 - which advertised dual-band PHY-LP support. Turns out it works. Whilst here, move up the support bit logging code so I can use it to debug this. Tested: * BCM4312 (pci id 0x4315); 5GHz STA operation

iost,
Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations. To test bwn(4) with bhnd(4), place the following lines in loader.conf(5): hw.bwn_pci.preferred="1" if_bwn_pci_load="YES bwn_v4_ucode_load="YES" bwn_v4_lp_ucode_load="YES" To verify that bwn(4) is using bhnd(4), you can check dmesg: bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0 ... or devinfo(8): pcib2 pci2 bwn_pci0 bhndb0 bhnd0 bwn0 ... bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently supported by bwn(4), including: - BCM4312 - BCM4318 - BCM4321 With minimal changes to the DMA code (not included in this commit), I was also able to test support for newer BCMA devices by bringing up basic working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets: - BCM43224 - BCM43225 Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation & Plausible Labs Differential Revision: https://reviews.freebsd.org/D13041

Add basic bwn(4) support for the (BCMA-based) BCM43224 and BCM43225. - Add the BCM4322X D11 core revision and missing BCM43224 PCI device ID to our device tables. - Disable the DMA engine parity check (rather than adding parity support to the to-be-replaced bwn(4) DMA implementation). Currently, N-PHY support in bwn(4) is GPL licensed, and is not included by default. Until this is replaced with Broadcom's ISC-licensed N-PHY implementation, bwn(4) must be rebuilt to enable N-PHY support. To build bwn(4) with N-PHY support, add the following lines to your kernel configuration file and rebuild the kernel (and modules): options BWN_GPL_PHY To test bwn(4) with a BCM43224/BCM43225 device, install the firmware from the net/bwn-firmware-kmod port, and place the following lines in loader.conf(5): hw.bwn_pci.preferred="1" if_bwn_pci_load="YES bwn_v4_ucode_load="YES" bwn_v4_n_ucode_load="YES" bwn_v4_lp_ucode_load="YES" Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation

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.

Revert r327828, r327949, r327953, r328016-r328026, r328041: Uses of mallocarray(9). The use of mallocarray(9) has rocketed the required swap to build FreeBSD. This is likely caused by the allocation size attributes which put extra pressure on the compiler. Given that most of these checks are superfluous we have to choose better where to use mallocarray(9). We still have more uses of mallocarray(9) but hopefully this is enough to bring swap usage to a reasonable level. Reported by: wosch PR: 225197

Tested: * BCM4321MC, STA mode, both 4xx and 666 firmware, DMA mode TODO: * The newer firmware ends up logging "warn: firmware state (0)"; not sure yet what's going on there. But, yes, it still works. I'm committing this via a BCM4321MC, 11a station, firmware rev 666. Obtained from: Linux b43 (TX/RX descriptor format for 5xx)

[bwn] implement firmware tx/rx versioning and fix RSSI calculation. Different versions of firmware have different requirments for TX/RX packet layouts (and other things, of course.) Currently the driver checks between 3xx and 4xx firmware by using the BWN_ISOLDFMT() macro, which doesn't take into account the 5xx firmware (which I think I need for the HT and N series PHY chips. I'll know when I do the port.) BWN_HDRSIZE() also needs to learn about the 5xx series firmware as well. So: * add a firmware version enum * populate it based on the firmware version we read at load time * don't finish loading if the firmware is the 5xx firmware; any code using BWN_ISOLDFMT or BWN_HDRSIZE needs updating (most notably the TX and RX bits.) Then, for RX RSSI: * write down and reimplement the b43 rssi calculation method; * use it for the correct PHYs (which are all the ones we support); * do the RSSI calculation before radiotap, not after. Tested: * Broadcom BCM4312, STA mode Obtained from: Linux b43 (careful writing and reimplementing; lots of integer math..)

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.

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations.

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.

Tested: * BCM4321MC, STA mode, both 4xx and 666 firmware, DMA mode TODO: * The newer firmware ends up logging "warn: firmware state (0)"; not sure yet what's going on there. But, yes, it still works.

[bwn] implement firmware tx/rx versioning and fix RSSI calculation. Different versions of firmware have different requirments for TX/RX packet layouts (and other things, of course.) Currently the driver checks between 3xx and 4xx firmware by using the BWN_ISOLDFMT() macro, which doesn't take into account the 5xx firmware (which I think I need for the HT and N series PHY chips. I'll know when I do the port.) BWN_HDRSIZE() also needs to learn about the 5xx series firmware as well. So: * add a firmware version enum * populate it based on the firmware version we read at load time * don't finish loading if the firmware is the 5xx firmware; any code using BWN_ISOLDFMT or BWN_HDRSIZE needs updating (most notably the TX and RX bits.) Then, for RX RSSI: * write down and reimplement the b43 rssi calculation method; * use it for the correct PHYs (which are all the ones we support); * do the RSSI calculation before radiotap, not after. Tested: * Broadcom BCM4312, STA mode Obtained from: Linux b43 (careful writing and reimplementing; lots of integer math..)

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.

[bwn] implement firmware tx/rx versioning and fix RSSI calculation. Different versions of firmware have different requirments for TX/RX packet layouts (and other things, of course.) Currently the driver checks between 3xx and 4xx firmware by using the BWN_ISOLDFMT() macro, which doesn't take into account the 5xx firmware (which I think I need for the HT and N series PHY chips. I'll know when I do the port.) BWN_HDRSIZE() also needs to learn about the 5xx series firmware as well. So: * add a firmware version enum * populate it based on the firmware version we read at load time * don't finish loading if the firmware is the 5xx firmware; any code using BWN_ISOLDFMT or BWN_HDRSIZE needs updating (most notably the TX and RX bits.) Then, for RX RSSI: * write down and reimplement the b43 rssi calculation method; * use it for the correct PHYs (which are all the ones we support); * do the RSSI calculation before radiotap, not after.

Fix: move counting into *_tx_update() (now otus(4) will zero out all node counters after every tx_update() call) Tested with: - Intel 3945BG (wpi(4)), STA mode. - WUSB54GC (rum(4)), STA / HOSTAP mode. - RTL8188EU (urtwn(4)), STA mode.

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.

[bwn] fill out phyctl_1 fields for N-PHY (and later, eventually.) N-PHY and later require a lot more plcp specific setup for the PHY to know what to transmit. I've been spoilt by the atheros, intel and realtek parts where you don't have to hand-assemble the PLCP but .. well, apparently Broadcom require a lot more work. This, and PHY-N itself, was the last major missing bit to get 11a OFDM transmit to work. Without this, CCK transmit worked but OFDM transmit would always fail (with stat.phy_err set to 0x80.) I have no idea what 0x80 is, and I went mad reading the broadcom vendor driver to try and figure it out. Tested: * BCM4312 (PHY-LP) * BCM4321 (PHY-N), 11a, 11bg.

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.

net80211 rate control framework (net80211 ratectl). This framework allows drivers to abstract the rate control algorithm and just feed the framework with the usable parameters.

The objective is to have more rate control algorithms in the net80211 stack so all drivers[0] can use it. Ideally, we'll have the well-known sample rate control algorithm in the net80211 at some point so all drivers can use it (not just ath). [0] all drivers that do rate control in software, that is.

[bwn] accurately(ish) account transmit/recieve failures for rate control. I noticed that it'd associate fine, but it'd quickly stop exchanging traffic. Receive was okay, but transmit just failed. Then I went "wlandebug +rate". I discovered it started at 36M OFDM, and then quickly rose to 54M, which then showed 0% transmit success. Then, I dug into how the completion path works. We are reading 'ack=0' in the TX status side, so .. then I discovered we were only processing the TX completion status /if/ ack=1. So, we'd only ever count successes; we'd never count failures, and thus the rate control code thought everything was a-ok. We also have to set retrycnt to something non-zero so it indeed does bring the rate down upon failure. So: * Delete the rate control completion code from the tx completion routine, it's just duplicate and never worked. Putting it behind 'if (status->ack) was pointless. * Move it to the PIO and DMA completion routines which actually do free the node reference and mbuf. We know at that point what the status is, so do it there. * Fake a retrycnt of 1 for now, so we at least count failures. Also: * Start adding comments about weird stuff I find with rate selection. In this instance, we shouldn't be selecting a fallback rate that doesn't match the currently configured mode (11a, 11b, 11g, etc.) This isn't perfect - AMRR does try 54mbit and takes a few packets before it figures out it's a bad idea - but it's better than nothing.

[bwn] fill out phyctl_1 fields for N-PHY (and later, eventually.) N-PHY and later require a lot more plcp specific setup for the PHY to know what to transmit. I've been spoilt by the atheros, intel and realtek parts where you don't have to hand-assemble the PLCP but .. well, apparently Broadcom require a lot more work. This, and PHY-N itself, was the last major missing bit to get 11a OFDM transmit to work. Without this, CCK transmit worked but OFDM transmit would always fail (with stat.phy_err set to 0x80.) I have no idea what 0x80 is, and I went mad reading the broadcom vendor driver to try and figure it out. Tested: * BCM4312 (PHY-LP) * BCM4321 (PHY-N), 11a, 11bg.

Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED. The origin of WEP comes from IEEE Std 802.11-1997 where it defines whether the frame body of MAC frame has been encrypted using WEP algorithm or not. IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates whether the frame is protected by a cryptographic encapsulation algorithm. Reviewed by: adrian, rpaulo

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.

Introduce bwn(4) support for the bhnd(4) bus. Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect found in post-2009 Broadcom Wi-Fi hardware, are not supported by siba_bwn(4). The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port) provides a unified kernel interface to a superset of the hardware supported by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their SSB or BCMA backplane. This diff introduces opt-in bwn(4) support for bhnd(4) by providing: - A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via bhnd(4) instead of siba_bwn(4). - A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally probes at a higher priority than the siba_bwn(4) PCI driver. - A set of compatibility shims that perform translation of bwn(4)'s siba_bwn function calls into their bhnd(9) API equivalents when bwn(4) is attached via a bhnd(4) bus parent. When bwn(4) is attached via siba_bwn(4), all siba_bwn function calls are simply passed through to their original implementations. To test bwn(4) with bhnd(4), place the following lines in loader.conf(5): hw.bwn_pci.preferred="1" if_bwn_pci_load="YES bwn_v4_ucode_load="YES" bwn_v4_lp_ucode_load="YES" To verify that bwn(4) is using bhnd(4), you can check dmesg: bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0 ... or devinfo(8): pcib2 pci2 bwn_pci0 bhndb0 bhnd0 bwn0 ... bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently supported by bwn(4), including: - BCM4312 - BCM4318 - BCM4321 With minimal changes to the DMA code (not included in this commit), I was also able to test support for newer BCMA devices by bringing up basic working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets: - BCM43224 - BCM43225 Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation & Plausible Labs Differential Revision: https://reviews.freebsd.org/D13041

[bwn] [bhnd] initial support for using bhnd for if_bwn devices. This is an initial work in progress to use the replacement bhnd bus code for devices which support it. * Add manpage updates for bhnd, bhndb, siba * Add kernel options for bhnd, bhndbus, etc * Add initial support in if_bwn_pci / if_bwn_mac for using bhnd as the bus transport for suppoted NICs * if_bwn_pci will eventually be the PCI bus glue to interface to bwn, which will use the right backend bus to attach to, versus direct nexus/bhnd attachments (as found in embedded broadcom devices.) The PCI glue defaults to probing at a lower level than the bwn glue, so bwn should still attach as per normal without a boot time tunable set. It's also not fully fleshed out - the bwn probe/attach code needs to be broken out into platform and bus specific things (just like ath, ath_pci, ath_ahb) before we can shift the driver over to using this.
