move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

wifi: mac80211: remove RX_DROP_UNUSABLE

Convert all instances of RX_DROP_UNUSABLE to indicate a better reason, and then remove RX_DROP_UNUSABLE. Signed-off-by: Johannes Berg

mac80211: make ieee80211_wep_init() return void

This function always returns 0, so there's no point in returning int. Make it void and remove the impossible error-path when calling it. Signed-off-by: Luca Coelho Link: https://lore.kernel.org/r/20200131111300.891737-11-luca@coelho.fi Signed-off-by: Johannes Berg

net/mac80211: move WEP handling to ARC4 library interface

2019-06-20T06:18:33+00:00

The WEP code in the mac80211 subsystem currently uses the crypto API to access the arc4 (RC4) cipher, which is overly complicated, and doesn't really have an upside in this particular case, since ciphers are always synchronous and therefore always implemented in software. Given that we have no accelerated software implementations either, it is much more straightforward to invoke a generic library interface directly.

crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm allocations

2018-11-20T06:26:55+00:00

'cipher' algorithms (single block ciphers) are always synchronous, so passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no effect. Many users therefore already don't pass it, but some still do. This inconsistency can cause confusion, especially since the way the 'mask' argument works is somewhat counterintuitive. Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags. This patch shouldn't change any actual behavior. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

mac80211: Add RX flag to indicate ICV stripped

mac80211: move WEP tailroom size check

Remove checking tailroom when adding IV as it uses only headroom, and move the check to the ICV generation that actually needs the tailroom.

When an IV is generated, only the MAC header is moved back. The network header location remains the same relative to the skb head, as the new IV is using headroom space that was reserved in advance. Signed-off-by: Arik Nemtsov Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg
