wifi: use struct_group to copy addresses

2022-09-03T14:40:06+00:00

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.

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

2019-07-26T11:22:47+00:00

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

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

lib80211: ratelimit key index mismatch

2015-12-04T13:43:32+00:00

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.

hostap: Don't use create_proc_read_entry()

2013-04-29T19:41:56+00:00

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

2011-09-13T19:45:02+00:00

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.
