2025-07-23wifi: brcmfmac: fix EXTSAE WPA3 connection failure due to AUTH TX failureTing-Ying Li2-21/+35
For WPA3-SAE Connection in EXTSAE mode, the userspace daemon is allowed to generate the SAE Auth frames. The driver uses the "mgmt_frame" FW IOVAR to transmit this MGMT frame. Before sending the IOVAR, the Driver is incorrectly treating the channel number read from the FW as a frequency value and again attempts to convert this into a channel number using ieee80211_frequency_to_channel(). This added an invalid channel number as part of the IOVAR request to the FW And some FW which strictly expects a valid channel would return BAD_CHAN error, while failing to transmit the driver requested SAE Auth MGMT frame. Fix this in the CYW vendor specific MGMT TX cfg80211 ops handler, by not treating the channel number read from the FW as frequency value and skip the attempt to convert it again into a channel number. Also fix this in the generic MGMT TX cfg80211 ops handler.

2025-07-21wifi: brcmfmac: fix P2P discovery failure in P2P peer due to missing P2P IEGokul Sivakumar1-4/+4
After commit bd99a3013bdc ("brcmfmac: move configuration of probe request IEs"), the probe request MGMT IE addition operation brcmf_vif_set_mgmt_ie() got moved from the brcmf_p2p_scan_prep() to the brcmf_cfg80211_scan(). Because of this, as part of the scan request handler for the P2P Discovery, vif struct used for adding the Probe Request P2P IE in firmware got changed from the P2PAPI_BSSCFG_DEVICE vif to P2PAPI_BSSCFG_PRIMARY vif incorrectly. So the firmware stopped adding P2P IE to the outgoing P2P Discovery probe requests frames and the other P2P peers were unable to discover this device causing a regression on the P2P feature. To fix this, while setting the P2P IE in firmware, properly use the vif of the P2P discovery wdev on which the driver received the P2P scan request. This is done by not changing the vif pointer, until brcmf_vif_set_mgmt_ie() is completed.

2025-06-24wifi: cfg80211/mac80211: Add support to get radio indexRoopni Devanathan4-8/+11
Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

After commit 92cadedd9d5f ("brcmfmac: Avoid keeping power to SDIO card unless WOWL is used"), the wifi adapter by default is turned off on suspend and then re-probed on resume. This conflicts with some embedded boards that require to remain powered. They will fail on resume with: brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout ieee80211 phy1: brcmf_bus_started: failed: -110 ieee80211 phy1: brcmf_attach: dongle is not responding: err=-110 brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed This commit checks for the Device Tree property 'cap-power-off-cards'. If this property is not set, it means that we do not have the capability to power off and should therefore remain powered.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core and debugfs updates from Greg KH: "Here is the big set of driver core and debugfs updates for 6.14-rc1. Included in here is a bunch of driver core, PCI, OF, and platform rust bindings (all acked by the different subsystem maintainers), hence the merge conflict with the rust tree, and some driver core api updates to mark things as const, which will also require some fixups due to new stuff coming in through other trees in this merge window. There are also a bunch of debugfs updates from Al, and there is at least one user that does have a regression with these, but Al is working on tracking down the fix for it. In my use (and everyone else's linux-next use), it does not seem like a big issue at the moment. Here's a short list of the things in here: - driver core rust bindings for PCI, platform, OF, and some i/o functions. We are almost at the "write a real driver in rust" stage now, depending on what you want to do. - misc device rust bindings and a sample driver to show how to use them - debugfs cleanups in the fs as well as the users of the fs api for places where drivers got it wrong or were unnecessarily doing things in complex ways. - driver core const work, making more of the api take const * for different parameters to make the rust bindings easier overall. - other small fixes and updates All of these have been in linux-next with all of the aforementioned merge conflicts, and the one debugfs issue, which looks to be resolved "soon"" * tag 'driver-core-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (95 commits) rust: device: Use as_char_ptr() to avoid explicit cast rust: device: Replace CString with CStr in property_present() devcoredump: Constify 'struct bin_attribute' devcoredump: Define 'struct bin_attribute' through macro rust: device: Add property_present() saner replacement for debugfs_rename() orangefs-debugfs: don't mess with ->d_name octeontx2: don't mess with ->d_parent or ->d_parent->d_name arm_scmi: don't mess with ->d_parent->d_name slub: don't mess with ->d_name sof-client-ipc-flood-test: don't mess with ->d_name qat: don't mess with ->d_name xhci: don't mess with ->d_iname mtu3: don't mess wiht ->d_iname greybus/camera - stop messing with ->d_iname mediatek: stop messing with ->d_iname netdevsim: don't embed file_operations into your structs b43legacy: make use of debugfs_get_aux() b43: stop embedding struct file_operations into their objects carl9170: stop embedding file_operations into their objects ...
2025-01-28wifi: brcmfmac: use random seed flag for BCM4355 and BCM4364 firmwareAditya Garg1-2/+2
Before 6.13, random seed to the firmware was given based on the logic whether the device had valid OTP or not, and such devices were found mainly on the T2 and Apple Silicon Macs. In 6.13, the logic was changed, and the device table was used for this purpose, so as to cover the special case of BCM43752 chip. During the transition, the device table for BCM4364 and BCM4355 Wi-Fi chips which had valid OTP was not modified, thus breaking Wi-Fi on these devices. This patch adds does the necessary changes, similar to the ones done for other chips.

2025-01-16wifi: brcmfmac: fix NULL pointer dereference in brcmf_txfinalize()Marcel Hamer1-0/+5
On removal of the device or unloading of the kernel module a potential NULL pointer dereference occurs. The following sequence deletes the interface: brcmf_detach() brcmf_remove_interface() brcmf_del_if() Inside the brcmf_del_if() function the drvr->if2bss[ifidx] is updated to BRCMF_BSSIDX_INVALID (-1) if the bsscfgidx matches. After brcmf_remove_interface() call the brcmf_proto_detach() function is called providing the following sequence: brcmf_detach() brcmf_proto_detach() brcmf_proto_msgbuf_detach() brcmf_flowring_detach() brcmf_msgbuf_delete_flowring() brcmf_msgbuf_remove_flowring() brcmf_flowring_delete() brcmf_get_ifp() brcmf_txfinalize() Since brcmf_get_ip() can and actually will return NULL in this case the call to brcmf_txfinalize() will result in a NULL pointer dereference inside brcmf_txfinalize() when trying to update ifp->ndev->stats.tx_errors. This will only happen if a flowring still has an skb. Although the NULL pointer dereference has only been seen when trying to update the tx statistic, all other uses of the ifp pointer have been guarded as well with an early return if ifp is NULL.

2024-12-09wifi: brcmfmac: fix brcmf_vif_clear_mgmt_ies when stopping APRenjaya Raga Zenta1-1/+5
This removes the following error log when stopping AP: ieee80211 phy0: brcmf_vif_set_mgmt_ie: vndr ie set error : -52 It happened if: 1) previously wlan interface was in station mode (wpa_supplicant) and connected to a hotspot 2) then started AP mode (hostapd) 3) and then stopped AP mode. The error happened when it tried to clear BRCMF_VNDR_IE_PRBREQ_FLAG. This flag is not set in `brcmf_config_ap_mgmt_ie`, but BRCMF_VNDR_IE_ASSOCRSP_FLAG is set instead.

2024-12-09wifi: brcmfmac: fix scatter-gather handling by detecting end of sg listNorbert van Bolhuis1-0/+5
The scatter-gather handling uses a pre-allocated list (with nents entries). If the driver runs out of sg entries it will result in an oops. Let's detect this instead and make the SDIO block transfer fail.

2024-12-04wifi: cfg80211: send MLO links tx power info in GET_INTERFACERameshkumar Sundaram1-1/+1
Currently, TX power is reported on interface/wdev level as part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links can be part of an interface/wdev and hence its necessary to report the TX power of each link. Add support to send tx power for all valid links of an MLD as part of NL80211_CMD_GET_INTERFACE request. As far as userspace is concerned, there is no behavioral change for Non-ML Interfaces. For ML interfaces, userspace should fetch TX power that is nested inside NL80211_ATTR_MLO_LINKS, similar to how channel info(NL80211_ATTR_WIPHY_FREQ) is fetched.
