mac80211: populate debugfs only after cfg80211 init

2020-04-29T14:33:18+00:00

commit 6cb5f3ea4654faf8c28b901266e960b1a4787b26 upstream. When fixing the initialization race, we neglected to account for the fact that debugfs is initialized in wiphy_register(), and some debugfs things went missing (or rather were rerooted to the global debugfs root). Fix this by adding debugfs entries only after wiphy_register(). This requires some changes in the rate control code since it currently adds debugfs at alloc time, which can no longer be done after the reordering.

mac80211: allow drivers to set max MTU

2019-09-11T07:33:29+00:00

Make it possibly for drivers to adjust the default max_mtu by storing it in the hardware struct and using that value for all interfaces. Signed-off-by: Wen Gong Link: https://lore.kernel.org/r/1567738137-31748-1-git-send-email-wgong@codeaurora.org Signed-off-by: Johannes Berg

mac80211: allow setting spatial reuse parameters from bss_conf

2019-07-31T09:00:52+00:00

Store the OBSS PD parameters inside bss_conf when bringing up an AP and/or when a station connects to an AP. This allows the driver to configure the HW accordingly. Signed-off-by: John Crispin Link: https://lore.kernel.org/r/20190730163701.18836-3-john@phrozen.org Signed-off-by: Johannes Berg

mac80211: propagate HE operation info into bss_conf

2019-07-29T14:39:37+00:00

Upon a successful assoc a station shall store the content of the HE operation element inside bss_conf so that the driver can setup the hardware accordingly.

mac80211: add IEEE80211_KEY_FLAG_GENERATE_MMIE to ieee80211_key_flags

2019-07-26T14:14:12+00:00

Add IEEE80211_KEY_FLAG_GENERATE_MMIE flag to ieee80211_key_flags in order to allow the driver to notify mac80211 to generate MMIE and that it requires sequence number generation only. This is a preliminary patch to add BIP_CMAC_128 hw support to mt7615 driver Signed-off-by: Lorenzo Bianconi Link: https://lore.kernel.org/r/dfe275f9aa0f1cc6b33085f9efd5d8447f68ad13.1563228405.git.lorenzo@kernel.org Signed-off-by: Johannes Berg

mac80211: add xmit rate to struct ieee80211_tx_status

2019-07-26T11:41:45+00:00

Right now struct ieee80211_tx_rate cannot hold HE rates. Lets use struct ieee80211_tx_status instead. This will also make the code future-proof for when we have EHT. Signed-off-by: John Crispin Link: https://lore.kernel.org/r/20190714154419.11854-2-john@phrozen.org Signed-off-by: Johannes Berg

mac80211: AMPDU handling for rekeys with Extended Key ID

2019-07-26T11:29:10+00:00

Extended Key ID allows A-MPDU sessions while rekeying as long as each A-MPDU aggregates only MPDUs with one keyid together. Drivers able to segregate MPDUs accordingly can tell mac80211 to not stop A-MPDU sessions when rekeying by setting the new flag IEEE80211_HW_AMPDU_KEYBORDER_SUPPORT.

mac80211: Simplify Extended Key ID API

2019-07-26T11:28:59+00:00

1) Drop IEEE80211_HW_EXT_KEY_ID_NATIVE and let drivers directly set the NL80211_EXT_FEATURE_EXT_KEY_ID flag. 2) Drop IEEE80211_HW_NO_AMPDU_KEYBORDER_SUPPORT and simply assume all drivers are unable to handle A-MPDU key borders. The new Extended Key ID API now requires all mac80211 drivers to set NL80211_EXT_FEATURE_EXT_KEY_ID when they implement set_key() and can handle Extended Key ID. For drivers not providing set_key() mac80211 itself enables Extended Key ID support, using the internal SW crypto services.

mac80211: add tx dequeue function for process context

2019-07-26T11:23:19+00:00

Since ieee80211_tx_dequeue() must not be called with softirqs enabled (i.e. from process context without proper disable of bottom halves), we add a wrapper that disables bottom halves before calling ieee80211_tx_dequeue() The new function is named ieee80211_tx_dequeue_ni() just as all other from-process-context versions found in mac80211. The documentation of ieee80211_tx_dequeue() is also updated so it mentions that the function should not be called from process context.

mac80211: remove unused and unneeded remove_sta_debugfs callback

2019-07-26T11:21:12+00:00

The remove_sta_debugfs callback in struct rate_control_ops is no longer used by any driver, as there is no need for it (the debugfs directory is already removed recursivly by the mac80211 core.) Because no one needs it, just remove it to keep anyone else from accidentally using it in the future. Cc: Johannes Berg Cc: "David S.
