Instead, remove the get_recvframe_data() entirely, as it's not possible for this to ever be NULL. Additionally add missing NULL checks after recvframe_pull() (which are present in the rtl8712 driver).

staging: rtl8723bs: Fix access-point mode deadlock Commit 54659ca026e5 ("staging: rtl8723bs: remove possible deadlock when disconnect (v2)") split the locking of pxmitpriv->lock vs sleep_q/lock into 2 locks in attempt to fix a lockdep reported issue with the locking order of the sta_hash_lock vs pxmitpriv->lock. But in the end this turned out to not fully solve the sta_hash_lock issue so commit a7ac783c338b ("staging: rtl8723bs: remove a second possible deadlock") was added to fix this in another way.

Fix it by removing the xmit_priv->lock around rtw_xmitframe_enqueue call inside rtl8723bs_hal_xmit and put it in a smaller critical section inside rtw_xmit_classifier, the only place where xmit_priv data are actually accessed. Replace spin_{lock,unlock}_bh(pxmitpriv->lock) in other tx paths leading to rtw_xmitframe_enqueue call with spin_{lock,unlock}_bh(psta->sleep_q.lock) - it's not clear why accessing a sleep_q was protected by a spinlock on xmitpriv->lock. This way is avoided the same faulty lock nesting order. Extra changes in v2 by Hans de Goede: -Lift the taking of the struct __queue.lock spinlock out of rtw_free_xmitframe_queue() into the callers this allows also protecting a bunch of related state in rtw_free_stainfo(): -Protect psta->sleepq_len on rtw_free_xmitframe_queue(&psta->sleep_q); -Protect struct tx_servq.tx_pending and tx_servq.qcnt when calling rtw_free_xmitframe_queue(&tx_servq.sta_pending) -This also allows moving the spin_lock_bh(&pxmitpriv->lock); to below the sleep_q free-ing code, avoiding another ABBA locking issue CC: Larry Finger <Larry.Finger@lwfinger.net> Co-developed-by: Hans de Goede <hdegoede@redhat.com> Tested-on: Lenovo Ideapad MiiX 300-10IBY Signed-off-by: Fabio Aiuto <fabioaiuto83@gmail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20210920145502.155454-1-hdegoede@redhat.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Revert "staging: rtl8723bs: remove possible deadlock when disconnect" This reverts commit 78a1614a81f06032055a25b7acd9965a81196433. There's been attempts to fix this, but it's not quite right yet, so just remove the original commit.

staging: rtl8723bs: remove header file ethernet.h The header file ehternet.h defines only two constants. #define ETHERNET_HEADER_SIZE 14 /* Ethernet Header Length */ #define LLC_HEADER_SIZE 6 /* LLC Header Length */ Both are only used in the file core/rtw_recv.c and ETHERNET_HEADER_SIZE just duplicates the in-kernel constant ETH_HLEN. Replace the usage of ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE into rtw_rev.h (renamed to LLC_HEADER_LENGTH) and remove the now unused header file ethernet.h.

staging: rtl8723bs: remove DBG_871X log argument This patch prepares the application of the semantic patch aimed to remove all DBG_871X logs. One occurrence of the DBG_871X macro has one repeated argument, that's not even comma separated value with the previous one nor a format string parameter associated. In normal conditions this worked, for the macro is usually not expanded (the do nothing behaviour), but if I try to apply the sempantic patch to remove all macro occurrences, all macros call after that abnormal declaration are left untouched (not removed). Remove all of the DBG_871X logs as they currently do nothing as they require the code to be modified by hand in order to be turned on. This obviously has not happened since the code was merged, so just remove them as they are unused.

staging: rtl8723bs: remove commented RT_TRACE calls in core/rtw_recv.c Remove commented RT_TRACE calls Remove all of the RT_TRACE logs in the core/rtw_recv.c file as they currently do nothing as they require the code to be modified by hand in order to be turned on. This obviously has not happened since the code was merged. Moreover it relies on an unneeded private log level tracing which overrides the in-kernel public one, so just remove them as they are unused.

But there is no clear timeline for that, so lets add this driver included in staging for now.
