The report is valid: doing the math in this function, with an input value
N=63 the variable s16tableIndex gets a value of 31. This value is used as
an index in the array log_table with 32 entries. But the next line is:
s16errorApproximation = (s16) qm_mulu16(u16offset,
(u16) (log_table[s16tableIndex + 1] -
log_table[s16tableIndex]));
With s16tableIndex + 1 we are trying an out-of-bounds access to the array.
The log_table array provides log2 values in q.15 format and the above
statement tries an error approximation with the next value. To fix this
issue add the next value to the array and update the comment accordingly.

So far our core code was calling brcmf_fws_process_skb which wasn't
a proper thing to do. If case of devices using msgbuf protocol fwsignal
shouldn't be used. It was an unnecessary extra layer simply calling
a protocol specifix txdata function.
Please note we already have txdata callback, but it's used for calls
between bcdc and fwsignal so it couldn't be simply used there.
This makes core code more generic (instead of bcdc/fwsignal specific).

A bugfix added a sanity check around the assignment and use of the
'is_11d' variable, which looks correct to me, but as the function is
rather complex already, this confuses the compiler to the point where
it can no longer figure out if the variable is always initialized
correctly:
brcm80211/brcmfmac/cfg80211.c: In function ‘brcmf_cfg80211_start_ap’:
brcm80211/brcmfmac/cfg80211.c:4586:10: error: ‘is_11d’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds an initialization for the newly introduced case in which
the variable should not really be used, in order to make the warning
go away.

Flowrings contain skbs waiting for transmission that were passed to us
by netif. It means we checked every one of them looking for 802.1x
Ethernet type. When deleting flowring we have to use freeing function
that will check for 802.1x type as well.
Freeing skbs without a proper check was leading to counter not being

Even with timeout increased to 950 ms we get WARNINGs from time to time.
It mostly happens on A-MPDU stalls (e.g. when station goes out of
range). It may take up to 5-10 secods for the firmware to recover and
for that time it doesn't process packets.
It's still useful to have a message on time out as it may indicate some
firmware problem and incorrect key update. Raising a WARNING however
wasn't really that necessary, it doesn't point to any driver bug anymore
and backtrace wasn't much useful.

In brcmf_sdio_kso_control() there is a retry loop as hardware may take
time to settle. However, when the call to brcmf_sdiod_regrb() returns
an error it is due to SDIO access failure and it makes no sense to wait
for hardware to settle. This patch aborts the loop after a number of
subsequent access errors.

The driver already supports the bcm4339 chipset but only for the variant
that shares the same modalias as the bcm4335, ie. sdio:c00v02D0d4335.
It turns out that there are also bcm4339 devices out there that have a
more distiguishable modalias sdio:c00v02D0d4339.

User-space can choose to omit NL80211_ATTR_SSID and only provide raw
IE TLV data. When doing so it can provide SSID IE with length exceeding
the allowed size. The driver further processes this IE copying it
into a local variable without checking the length. Hence stack can be
corrupted and used as exploit.

The struct cfg80211_pmksa defines its bssid field as:
const u8 *bssid;
contrary to struct brcmf_pmksa, which uses:
u8 bssid[ETH_ALEN];
Therefore in brcmf_cfg80211_del_pmksa(), &pmksa->bssid takes the address
of this field (of type u8**), not the one of its content (which would be
u8*). Remove the & operator to make brcmf_dbg("%pM") and memcmp()
behave as expected.
This bug have been found using a custom static checker (which checks the
usage of %p... attributes at build time). It has been introduced in
commit 6c404f34f2 ("brcmfmac: Cleanup pmksa cache handling code"),
which replaced pmksa->bssid by &pmksa->bssid while refactoring the code,
without modifying struct cfg80211_pmksa definition.
Replace &pmk[i].bssid with pmk[i].bssid too to make the code clearer,
this change does not affect the semantic.

We get 1 warning when building kernel with W=1:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/tracepoint.c:23:6: warning: no previous prototype for '__brcmf_err' [-Wmissing-prototypes]
In fact, this function is declared in brcmfmac/debug.h, so this patch
adds missing header dependencies.

wlc_phy_txpower_get_current() does a logical OR of power->flags, which
presumes that power.flags was initiliazed earlier by the caller,
unfortunately, this is not the case, so make sure we zero out the struct
tx_power before calling into wlc_phy_txpower_get_current().
