* wifi: mac80211: simplify non-chanctx driversJohannes Berg2024-02-081-0/+4
| | | | | | | | | | | | | 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.

* wifi: plfxlc: fix clang-specific fortify warningDmitry Antipov2023-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When compiling with clang 16.0.6 and CONFIG_FORTIFY_SOURCE=y, I've noticed the following (somewhat confusing due to absence of an actual source code location): In file included from drivers/net/wireless/purelifi/plfxlc/mac.c:6: In file included from ./include/linux/netdevice.h:24: In file included from ./include/linux/timer.h:6: In file included from ./include/linux/ktime.h:24: In file included from ./include/linux/time.h:60: In file included from ./include/linux/time32.h:13: In file included from ./include/linux/timex.h:67: In file included from ./arch/x86/include/asm/timex.h:5: In file included from ./arch/x86/include/asm/processor.h:23: In file included from ./arch/x86/include/asm/msr.h:11: In file included from ./arch/x86/include/asm/cpumask.h:5: In file included from ./include/linux/cpumask.h:12: In file included from ./include/linux/bitmap.h:11: In file included from ./include/linux/string.h:254: ./include/linux/fortify-string.h:592:4: warning: call to '__read_overflow2_field' declared with 'warning' attribute: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Wattribute-warning] __read_overflow2_field(q_size_field, size); The compiler actually complains on 'plfxlc_get_et_strings()' where fortification logic inteprets call to 'memcpy()' as an attempt to copy the whole 'et_strings' array from its first member and so issues an overread warning. This warning may be silenced by passing an address of the whole array and not the first member to 'memcpy()'.

* Fix nomenclature for USB and PCI wireless devicesAlan Stern2023-08-251-1/+1
| | | | | | | | | | | | | | | | | | | | | A mouse that uses a USB connection is called a "USB mouse" device (or "USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi adapter that connects to the host computer via USB is a "USB wireless" device, not a "wireless USB" device. (The latter term more properly refers to a defunct Wireless USB specification, which described a technology for sending USB protocol messages over an ultra wideband radio link.) Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a "PCIe wireless" device, not a "wireless PCIe" device. Rephrase the text in the kernel source where the word ordering is wrong.

* wireless: add plfxlc driver for pureLiFi X, XL, XC devicesSrinivasan Raju2022-04-2510-0/+2542
This is a driver for pureLiFi X, XL, XC devices which use light to transmit data, so they are not compatible with normal Wi-Fi devices. The driver uses separate NL80211_BAND_LC band to distinguish from Wi-Fi. The driver is based on 802.11 softMAC Architecture and uses native 802.11 for configuration and management. Station and Ad-Hoc modes are supported. The driver is compiled and tested in ARM, x86 architectures and compiled in powerpc architecture. This driver implementation has been based on the zd1211rw driver.
