wifi: mac80211: reorg some iface data structs for MLD

2022-06-20T10:55:06+00:00

Start reorganizing interface related data structures toward MLD. The most complex part here is for the keys, since we have to split the various kinds of GTKs off to the link but still need to use (for WEP) the other keys as a fallback even for multicast frames. Signed-off-by: Johannes Berg

mac80211: remove unused macros

2022-02-04T15:26:27+00:00

Various macros in mac80211 aren't used, remove them. In one case it's used under ifdef, so ifdef it for the W=2 warning.

mac80211: Support BIGTK configuration for Beacon protection

2020-02-24T09:35:57+00:00

Extend mac80211 key configuration to support the new BIGTK with key index values 6 and 7. Support for actually protecting Beacon frames (adding the MME in AP mode and checking it in STA mode) is covered in separate commits.

mac80211: no need to check return value of debugfs_create functions

2019-06-14T14:08:28+00:00

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

mac80211: move TKIP TX IVs to public part of key struct

2016-02-24T08:04:38+00:00

Some drivers/devices might want to set the IVs by themselves (and still let mac80211 generate MMIC). Specifically, this is needed when the device does offloading at certain times, and the driver has to make sure that the IVs of new tx frames (from the host) are synchronized with IVs that were potentially used during the offloading. Similarly to CCMP, move the TX IVs of TKIP keys to the public part of the key struct, and export a function to add the IV right into the crypto header. The public tx_pn field is defined as atomic64, so define TKIP_PN_TO_IV16/32 helper macros to convert it to iv16/32 when needed. Since the iv32 used for the p1k cache is taken directly from the frame, we can safely remove iv16/32 from being protected by tkip.txlock.

mac80211: allow writing TX PN in debugfs

2015-09-29T13:56:50+00:00

For certain tests, for example replay detection, it can be useful to be able to influence/set the PN used in outgoing packets. Make it possible to change the TX PN in debugfs. For now, this doesn't support TKIP since I haven't needed it, but there's no reason it couldn't be added if necessary. Note that this must be used very carefully: it could, for example, be used to make "valid replays" where the PN reuse happens on a different TID. This couldn't be done by an attacker since the TID is protected as part of the AAD. Signed-off-by: Johannes Berg

mac80211: remove key TX/RX counter

2015-07-17T13:38:01+00:00

This counter is inherently racy (since it can be incremented by RX as well as by concurrent TX) and only available in debugfs. Instead of fixing it to be per-CPU or similar, remove it for now. If needed it should be added without races and with proper nl80211, perhaps even addressing the threshold reporting TODO item that's been there since the code was originally added.
