Subject: [PATCH wireless-next 0/2] wifi: nxpwifi: fix two block ack teardown bugs
Date: Wed, 26 Aug 2026 00:17:08 +0100 [thread overview]
Message-ID: <20260825231834.244783-1-devnexen@gmail.com> (raw)
Two independent bugs in the block ack teardown paths, both found by code
inspection on next-20260825 and compile tested only.
The first leaves nxpwifi_11n_delete_tx_ba_stream_tbl_entry() unable to
delete anything, so Tx BA stream entries leak on every teardown and
aggregation eventually stops being negotiated. The second holds the RCU
read lock across a teardown that sleeps, which splats under
CONFIG_DEBUG_ATOMIC_SLEEP when a station deauthenticates from the AP.
