wifi: cfg80211/mac80211: remove dependency on non-existing optionCommit ffbd0c8c1e7f ("wifi: mac80211: add an element parsing unit test")and commit 730eeb17bbdd ("wifi: cfg80211: add first kunit tests, forelement defrag") add new configs that depend on !KERNEL_6_2, but the configoption KERNEL_6_2 does not exist in the tree. This dependency is used forhandling backporting to restrict the option to certain kernels but thisreally should not be carried around the mainline kernel tree.Clean up this needless dependency on the non-existing option KERNEL_6_2.Link: https://lore.kernel.org/lkml/CAKXUXMyfrM6amOR7Ysim3WNQ-Ckf9HJDqRhAoYmLXujo1UV+yA@mail.gmail.com/Signed-off-by: Lukas Bulwahn Signed-off-by: Johannes Berg List of files: /linux-6.15/net/mac80211/Kconfig

b64acb28 - ath9k: fix build error with LEDS_CLASS=m

Mon, 25 Jan 2021 11:36:42 +0000

ath9k: fix build error with LEDS_CLASS=mWhen CONFIG_ATH9K is built-in but LED support is in a loadablemodule, both ath9k drivers fails to link:x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_deinit_leds':gpio.c:(.text+0x36): undefined reference to `led_classdev_unregister'x86_64-linux-ld: drivers/net/wireless/ath/ath9k/gpio.o: in function `ath_init_leds':gpio.c:(.text+0x179): undefined reference to `led_classdev_register_ext'The problem is that the 'imply' keyword does not enforce any dependencybut is only a weak hint to Kconfig to enable another symbol from adefconfig file.Change imply to a 'depends on LEDS_CLASS' that prevents the incorrectconfiguration but still allows building the driver without LED support.The 'select MAC80211_LEDS' is now ensures that the LED support isactually used if it is present, and the added Kconfig dependencyon MAC80211_LEDS ensures that it cannot be enabled manually when ithas no effect.Fixes: 197f466e93f5 ("ath9k_htc: Do not select MAC80211_LEDS by default")Signed-off-by: Arnd Bergmann Acked-by: Johannes Berg Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20210125113654.2408057-1-arnd@kernel.org List of files: /linux-6.15/net/mac80211/Kconfig

5fdb3735 - net/mac80211: move WEP handling to ARC4 library interface

Wed, 12 Jun 2019 16:19:54 +0000

net/mac80211: move WEP handling to ARC4 library interfaceThe WEP code in the mac80211 subsystem currently uses the cryptoAPI to access the arc4 (RC4) cipher, which is overly complicated,and doesn't really have an upside in this particular case, sinceciphers are always synchronous and therefore always implemented insoftware. Given that we have no accelerated software implementationseither, it is much more straightforward to invoke a generic libraryinterface directly.Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu List of files: /linux-6.15/net/mac80211/Kconfig

c8d10cbd - mac80211: rewrite Kconfig text for mesh

mac80211: rewrite Kconfig text for meshLubomir Rintel recently pointed out a dead link for o11s.org, andrepointed it to a still live, but also stale website. As far as Iknow, no one is updating the content at open80211s.org.Since this Kconfig text was originally written, though, the 802.11smesh drafts were approved and ultimately rolled into 802.11 proper.Meanwhile, the implementation has converged on the final standard,so we can lose all of the text here and provide something that's alittle more helpful and accurate.Signed-off-by: Bob Copeland Reviewed-by: Lubomir Rintel Reviewed-by: Steve deRosier Signed-off-by: Johannes Berg List of files: /linux-6.15/net/mac80211/Kconfig

fe8de3da - mac80211: fils_aead: Use crypto api CMAC shash rather than bare cipher

Mon, 06 Feb 2017 10:49:27 +0000

mac80211: fils_aead: Use crypto api CMAC shash rather than bare cipherSwitch the FILS AEAD code to use a cmac(aes) shash instantiated by thecrypto API rather than reusing the open coded implementation inaes_cmac_vector(). This makes the code more understandable, and allowsplatforms to implement cmac(aes) in a more secure (*) and efficient waythan is typically possible when using the AES cipher directly.So replace the crypto_cipher by a crypto_shash, and update the aes_s2v()routine to call the shash interface directly.* In particular, the generic table based AES implementation is sensitive to known-plaintext timing attacks on the key, to which AES based MAC algorithms are especially vulnerable, given that their plaintext is not usually secret. Time invariant alternatives are available (e.g., based on SIMD algorithms), but may incur a setup cost that is prohibitive when operating on a single block at a time, which is why they don't usually expose the cipher API.Signed-off-by: Ard Biesheuvel Signed-off-by: Johannes Berg List of files: /linux-6.15/net/mac80211/Kconfig
