# SPDX-License-Identifier: GPL-2.0-only config WIRELESS_EXT bool config WEXT_CORE def_bool y depends on CFG80211_WEXT || WIRELESS_EXT config WEXT_PROC def_bool y depends on PROC_FS depends on WEXT_CORE config WEXT_SPY bool config WEXT_PRIV bool config CFG80211 tristate "cfg80211 - wireless configuration API" depends on RFKILL || !RFKILL select FW_LOADER select CRC32 # may need to update this when certificates are changed and are # using a different algorithm, though right now they shouldn't # (this is here rather than below to allow it to be a module) select CRYPTO_SHA256 if CFG80211_USE_KERNEL_REGDB_KEYS help cfg80211 is the Linux wireless LAN (802.11) configuration API. Enable this if you have a wireless device. For more information refer to documentation on the wireless wiki: https://wireless.wiki.kernel.org/en/developers/Documentation/cfg80211 When built as a module it will be called cfg80211. if CFG80211 config NL80211_TESTMODE bool "nl80211 testmode command" help The nl80211 testmode command helps implementing things like factory calibration or validation tools for wireless chips. Select this option ONLY for kernels that are specifically built for such purposes. Debugging tools that are supposed to end up in the hands of users should better be implemented with debugfs. Say N. config CFG80211_DEVELOPER_WARNINGS bool "enable developer warnings" default n help This option enables some additional warnings that help cfg80211 developers and driver developers, but beware that they can also trigger due to races with userspace. For example, when a driver reports that it was disconnected from the AP, but the user disconnects manually at the same time, the warning might trigger spuriously due to races. Say Y only if you are developing cfg80211 or a driver based on it (or mac80211). config CFG80211_CERTIFICATION_ONUS bool "cfg80211 certification onus" depends on EXPERT default n help You should disable this option unless you are both capable and willing to ensure your system will remain regulatory compliant with the features available under this option. Some options may still be under heavy development and for whatever reason regulatory compliance has not or cannot yet be verified. Regulatory verification may at times only be possible until you have the final system in place. This option should only be enabled by system integrators or distributions that have done work necessary to ensure regulatory certification on the system with the enabled features. Alternatively you can enable this option if you are a wireless researcher and are working in a controlled and approved environment by your local regulatory agency. config CFG80211_REQUIRE_SIGNED_REGDB bool "require regdb signature" if CFG80211_CERTIFICATION_ONUS default y select SYSTEM_DATA_VERIFICATION help Require that in addition to the "regulatory.db" file a "regulatory.db.p7s" can be loaded with a valid PKCS#7 signature for the regulatory.db file made by one of the keys in the certs/ directory. config CFG80211_USE_KERNEL_REGDB_KEYS bool "allow regdb keys shipped with the kernel" if CFG80211_CERTIFICATION_ONUS default y depends on CFG80211_REQUIRE_SIGNED_REGDB help Allow the regulatory database to be signed by one of the keys for which certificates are part of the kernel sources (in net/wireless/certs/). This is currently only Seth Forshee's key, who is the regulatory database maintainer. config CFG80211_EXTRA_REGDB_KEYDIR string "additional regdb key directory" if CFG80211_CERTIFICATION_ONUS depends on CFG80211_REQUIRE_SIGNED_REGDB help If selected, point to a directory with DER-encoded X.509 certificates like in the kernel sources (net/wireless/certs/) that shall be accepted for a signed regulatory database. Note that you need to also select the correct CRYPTO_<hash> modules for your certificates, and if cfg80211 is built-in they also must be. config CFG80211_REG_CELLULAR_HINTS bool "cfg80211 regulatory support for cellular base station hints" depends on CFG80211_CERTIFICATION_ONUS help This option enables support for parsing regulatory hints from cellular base stations. If enabled and at least one driver claims support for parsing cellular base station hints the regulatory core will allow and parse these regulatory hints. The regulatory core will only apply these regulatory hints on drivers that support this feature. You should only enable this feature if you have tested and validated this feature on your systems. config CFG80211_REG_RELAX_NO_IR bool "cfg80211 support for NO_IR relaxation" depends on CFG80211_CERTIFICATION_ONUS help This option enables support for relaxation of the NO_IR flag for situations that certain regulatory bodies have provided clarifications on how relaxation can occur. This feature has an inherent dependency on userspace features which must have been properly tested and as such is not enabled by default. A relaxation feature example is allowing the operation of a P2P group owner (GO) on channels marked with NO_IR if there is an additional BSS interface which associated to an AP which userspace assumes or confirms to be an authorized master, i.e., with radar detection support and DFS capabilities. However, note that in order to not create daisy chain scenarios, this relaxation is not allowed in cases where the BSS client is associated to P2P GO and in addition the P2P GO instantiated on a channel due to this relaxation should not allow connection from non P2P clients. The regulatory core will apply these relaxations only for drivers that support this feature by declaring the appropriate channel flags and capabilities in their registration flow. config CFG80211_DEFAULT_PS bool "enable powersave by default" default y help This option enables powersave mode by default. If this causes your applications to misbehave you should fix your applications instead -- they need to register their network latency requirement, see Documentation/power/pm_qos_interface.rst. config CFG80211_DEBUGFS bool "cfg80211 DebugFS entries" depends on DEBUG_FS help You can enable this if you want debugfs entries for cfg80211. If unsure, say N. config CFG80211_CRDA_SUPPORT bool "support CRDA" if EXPERT default y help You should enable this option unless you know for sure you have no need for it, for example when using the regulatory database loaded as a firmware file. If unsure, say Y. config CFG80211_WEXT bool "cfg80211 wireless extensions compatibility" if !CFG80211_WEXT_EXPORT select WEXT_CORE default y if CFG80211_WEXT_EXPORT help Enable this option if you need old userspace for wireless extensions with cfg80211-based drivers. config CFG80211_WEXT_EXPORT bool help Drivers should select this option if they require cfg80211's wext compatibility symbols to be exported. endif # CFG80211 config LIB80211 tristate default n help This options enables a library of common routines used by IEEE802.11 wireless LAN drivers. Drivers should select this themselves if needed. config LIB80211_CRYPT_WEP tristate select CRYPTO_LIB_ARC4 config LIB80211_CRYPT_CCMP tristate select CRYPTO select CRYPTO_AES select CRYPTO_CCM config LIB80211_CRYPT_TKIP tristate select CRYPTO_LIB_ARC4 config LIB80211_DEBUG bool "lib80211 debugging messages" depends on LIB80211 default n help You can enable this if you want verbose debugging messages from lib80211. If unsure, say N.
