2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg
There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

2023-10-23wifi: wl1251: replace deprecated strncpy with strscpyJustin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. Based on other assignments of similar fw_version fields we can see that NUL-termination is required but not NUL-padding: ethernet/intel/ixgbe/ixgbe_ethtool.c 1111: strscpy(drvinfo->fw_version, adapter->eeprom_id, 1112: sizeof(drvinfo->fw_version)); ethernet/intel/igc/igc_ethtool.c 147: scnprintf(adapter->fw_version, 148: sizeof(adapter->fw_version), 153: strscpy(drvinfo->fw_version, adapter->fw_version, 154: sizeof(drvinfo->fw_version)); wireless/broadcom/brcm80211/brcmfmac/core.c 569: strscpy(info->fw_version, drvr->fwver, sizeof(info->fw_version)); wireless/broadcom/brcm80211/brcmsmac/main.c 7867: snprintf(wlc->wiphy->fw_version, 7868: sizeof(wlc->wiphy->fw_version), "%u.%u", rev, patch); wireless/broadcom/b43legacy/main.c 1765: snprintf(wiphy->fw_version, sizeof(wiphy->fw_version), "%u.%u", wireless/broadcom/b43/main.c 2730: snprintf(wiphy->fw_version, sizeof(wiphy->fw_version), "%u.%u", wireless/intel/iwlwifi/dvm/main.c 1465: snprintf(priv->hw->wiphy->fw_version, 1466: sizeof(priv->hw->wiphy->fw_version), wireless/intel/ipw2x00/ipw2100.c 5905: snprintf(info->fw_version, sizeof(info->fw_version), "%s:%d:%s", A suitable replacement is `strscpy` due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.

We'll use bss_conf for per-link configuration later, so move out all the non-link-specific data out into a new struct ieee80211_vif_cfg used in the vif.

2021-12-16wl1251: specify max. IE lengthMerlijn Wajer
This fix is similar to commit 77c91295ea53 ("wil6210: specify max. IE length"). Without the max IE length set, wpa_supplicant cannot operate using the nl80211 interface. This patch is a workaround - the number 512 is taken from the wlcore driver, but note that per Paul Fertser: there's no correct number because the driver will ignore the data passed in extra IEs.

2018-02-27wl1251: Set generated MAC address back to NVS dataPali Rohár
In case there is no valid MAC address kernel generates random one. This patch propagate this generated MAC address back to NVS data which will be uploaded to wl1251 chip. So HW would have same MAC address as linux kernel uses. This should not change any functionality, but it is better to tell wl1251 correct mac address since beginning of chip usage.

2018-02-27wl1251: Parse and use MAC address from supplied NVS dataPali Rohár
This patch implements parsing MAC address from NVS data which are sent to wl1251 chip. Calibration NVS data could contain valid MAC address and it will be used instead of randomly generated one. This patch also moves code for requesting NVS data from userspace to driver initialization code to make sure that NVS data will be there at time when permanent MAC address is needed. Calibration NVS data for wl1251 are device specific. Every device with wl1251 chip should have been calibrated in factory and needs to provide own calibration data. Default example file wl1251-nvs.bin, found in linux-firmware repository, contains MAC address 00:00:20:07:03:09. So this MAC address is marked as invalid as it is not real device specific address, just example one.

2014-01-09wl1251: fix channel switching in monitor modeDavid Gnedt
Use the ENABLE_RX command for channel switching when no interface is present (monitor mode only). The advantage of ENABLE_RX is that it leaves the tx data path disabled in firmware, whereas the usual JOIN command seems to transmit some frames at firmware level.

2014-01-09wl1251: fix scan behaviour while not associatedDavid Gnedt
With a dissasociated card I often encoutered very long scan delays. My guess is that it has something to do with the cards DTIM handling and another firmware bug mentioned in the TI WLAN driver, which is described as the card may never end scanning if the channel is overloaded because it can't send probe requests. I think the firmware somehow also tries to receive DTIM messages when the BSSID is not set. Therefore most of the time it waits for DTIM messages and can't do scanning work. Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY bit for scans in disassociated state.

This value is no longer used by mac80211, and practically no driver ever set it to a correct value anyway, so remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-03-25mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chanKarl Beldan
Drivers that don't use chanctxes cannot perform VHT association because they still use a "backward compatibility" pair of {ieee80211_channel, nl80211_channel_type} in ieee80211_conf and ieee80211_local.

2013-02-11mac80211: remove IEEE80211_HW_SCAN_WHILE_IDLEJohannes Berg
There are only a few drivers that use HW scan, and all of those don't need a non-idle transition before starting the scan -- some don't even care about idle at all. Remove the flag and code associated with it. The only driver that really actually needed this is wl1251 and it can just do it itself in the hw_scan callback -- implement that.
