wifi: ipw2x00/lib80211: move remaining lib80211 into libipw

2024-10-08T19:52:26Z

There's already much code in libipw that used to be shared with more drivers, but now with the prior cleanups, those old Intel ipw2x00 drivers are also the only ones using whatever is now left of lib80211. Move lib80211 entirely into libipw. Link: https://patch.msgid.link/20241007202707.915ef7b9e7c7.Ib9876d2fe3c90f11d6df458b16d0b7d4bf551a8d@changeid Signed-off-by: Johannes Berg

wifi: lib80211: Constify struct lib80211_crypto_ops

2024-08-27T08:28:51Z

Now that functions in lib80211 handle "const struct lib80211_crypto_ops", some structure can be constified as well. Constifying these structures moves some data to a read-only section, so increase overall security.

wifi: use struct_group to copy addresses

2022-09-03T14:40:06Z

We sometimes copy all the addresses from the 802.11 header for the AAD, which may cause complaints from fortify checks. Use struct_group() to avoid the compiler warnings/errors. Change-Id: Ic3ea389105e7813b22095b295079eecdabde5045 Signed-off-by: Johannes Berg

lib80211: use crypto API ccm(aes) transform for CCMP processing

2019-07-26T11:22:47Z

Instead of open coding the CCM aead mode in the driver, and invoking the AES block cipher block by block, use a ccm(aes) aead transform which already encapsulates this functionality. This is a cleaner use of the crypto API, and permits optimized implementations to be used, which are typically much faster and deal more efficiently with the SIMD register file, which usually needs to be preserved/restored in order to use special AES instructions.

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

2018-11-20T06:26:55Z

'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

lib80211: ratelimit key index mismatch

2015-12-04T13:43:32Z

This indicates a driver key selection issue, but even then there's no point in printing it all the time, so ratelimit it. Also remove the priv pointer from it -- people debugging will only have a single device anyway and it's useless as anything but a cookie. Signed-off-by: Johannes Berg

hostap: Don't use create_proc_read_entry()

2013-04-29T19:41:56Z

Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead.

wireless: Remove unnecessary OOM logging messages

2011-09-13T19:45:02Z

Removing unnecessary messages saves code and text. Site specific OOM messages are duplications of a generic MM out of memory message and aren't really useful, so just delete them. Signed-off-by: Joe Perches Signed-off-by: John W. Linville
