When freeing rx_cb->rx_skb, the pointer is not set to NULL,
a later rsi_rx_done_handler call will try to read the freed
address.
This bug will very likley lead to double free, although
detected early as use-after-free bug.
The bug is triggerable with a compromised/malfunctional usb
device. After applying the patch, the same input no longer
triggers the use-after-free.
Attached is the kasan report from fuzzing.

The module parameters are missing dev_oper_mode 12, BT classic alone,
add it. Moreover, the parameters encode newlines, which ends up being
printed malformed e.g. by modinfo, so fix that too.
However, the module parameter string is duplicated in both USB and SDIO
modules and the dev_oper_mode mode enumeration in those module parameters
is a duplicate of macros used by the driver. Furthermore, the enumeration
is confusing.
So, deduplicate the module parameter string and use __stringify() to
encode the correct mode enumeration values into the module parameter
string. Finally, replace 'Wi-Fi' with 'Wi-Fi alone' and 'BT' with
'BT classic alone' to clarify what those modes really mean.

P2P client mode was only working the first time.
On subsequent connection attempts the group was successfully created but
no data was sent (no transmitted data packets were seen with a sniffer).
The reason for this was that the hardware was being configured in fixed
rate mode with rate RSI_RATE_1 (1Mbps) which is not valid in the 5GHz band.
In P2P mode wpa_supplicant uses NL80211_CMD_SET_TX_BITRATE_MASK to disallow
the 11b rates in the 2.4GHz band which updated common->fixedrate_mask.
rsi_set_min_rate() then used the fixedrate_mask to calculate the minimum
allowed rate, or 0xffff = auto if none was found.
However that calculation did not account for the different rate sets
allowed in the different bands leading to the error.
Fixing set_min_rate() would result in 6Mb/s being used all the time
which is not what we want either.
The reason the problem did not occur on the first connection is that
rsi_mac80211_set_rate_mask() only updated the fixedrate_mask for
the *current* band. When it was called that was still 2.4GHz as the
switch is done later. So the when set_min_rate() was subsequently
called after the switch to 5GHz it still had a mask of zero, leading
to defaulting to auto mode.
Fix this by differentiating the case of a single rate being
requested, in which case the hardware will be used in fixed rate
mode with just that rate, and multiple rates being requested,
in which case we remain in auto mode but the firmware rate selection
algorithm is configured with a restricted set of rates.

My previous patch checked if encryption should be enabled by directly
checking info->control.hw_key (like the downstream driver).
However that missed that the control and driver_info members of
struct ieee80211_tx_info are union fields.
Due to this when rsi_core_xmit() updates fields in "tx_params"
(driver_info) it can overwrite the control.hw_key, causing the result
of the later test to be incorrect.
With the current structure layout the first byte of control.hw_key is
overlayed with the vap_id so, since we only test if control.hw_key is
NULL / non NULL, a non zero vap_id will incorrectly enable encryption.
In basic STA and AP modes the vap_id is always zero so it works but in
P2P client mode a second VIF is created causing vap_id to be non zero
and hence encryption to be enabled before keys have been set.
Fix this by extracting the key presence flag to a new field in the driver
private tx_params structure and populating it first.

When BT coexistence is enabled (eg oper mode 13, which is the default)
the initialisation on startup sometimes silently fails.
In a normal initialisation we see

rsi_91x: rsi_load_9116_firmware: Loading chunk 2
rsi_91x: Max Stations Allowed = 1
But sometimes the last log is missing and the wlan net device is
not created.
Running a userspace loop that resets the hardware via a GPIO shows the
problem occurring ~5/100 resets.
The problem does not occur in oper mode 1 (wifi only).
Adding logs shows that the initialisation state machine requests a MAC
reset via rsi_send_reset_mac() but the firmware does not reply, leading
to the initialisation sequence being incomplete.
Fix this by delaying attaching the BT adapter until the wifi
initialisation has completed.
With this applied I have done > 300 reset loops with no errors.

In AP mode WPA2-PSK connections were not established.
The reason was that the AP was sending the first message
of the 4 way handshake encrypted, even though no pairwise
key had (correctly) yet been set.
Encryption was enabled if the "security_enable" driver flag
was set and encryption was not explicitly disabled by
IEEE80211_TX_INTFL_DONT_ENCRYPT.
However security_enable was set when *any* key, including
the AP GTK key, had been set which was causing unwanted
encryption even if no key was avaialble for the unicast
packet to be sent.
Fix this by adding a check that we have a key and drop
the old security_enable driver flag which is insufficient
and redundant.
The Redpine downstream out of tree driver does it this way too.
Regarding the Fixes tag the actual code being modified was
introduced earlier, with the original driver submission, in
dad0d04fa7ba ("rsi: Add RS9113 wireless driver"), however
at that time AP mode was not yet supported so there was
no bug at that point.
So I have tagged the introduction of AP support instead
which was part of the patch set "rsi: support for AP mode" [1]
It is not clear whether AP WPA has ever worked, I can see nothing
on the kernel side that broke it afterwards yet the AP support
patch series says "Tests are performed to confirm aggregation,
connections in WEP and WPA/WPA2 security."
One possibility is that the initial tests were done with a modified
userspace (hostapd).

The interrupt handling of the RS911x is particularly heavy. For each RX
packet, the card does three SDIO transactions, one to read interrupt
status register, one to RX buffer length, one to read the RX packet(s).
This translates to ~330 uS per one cycle of interrupt handler. In case
there is more incoming traffic, this will be more.
The drivers/mmc/core/sdio_irq.c has the following comment, quote "Just
like traditional hard IRQ handlers, we expect SDIO IRQ handlers to be
quick and to the point, so that the holding of the host lock does not
cover too much work that doesn't require that lock to be held."
The RS911x interrupt handler does not fit that. This patch therefore
changes it such that the entire IRQ handler is moved to the RX thread
instead, and the interrupt handler only wakes the RX thread.
This is OK, because the interrupt handler only does things which can
also be done in the RX thread, that is, it checks for firmware loading
error(s), it checks buffer status, it checks whether a packet arrived
and if so, reads out the packet and passes it to network stack.
Moreover, this change permits removal of a code which allocated an
skbuff only to get 4-byte-aligned buffer, read up to 8kiB of data
into the skbuff, queue this skbuff into local private queue, then in
RX thread, this buffer is dequeued, the data in the skbuff as passed
to the RSI driver core, and the skbuff is deallocated. All this is
replaced by directly calling the RSI driver core with local buffer.

In case RSI9116 SDIO WiFi operates in STA mode against Intel 9260 in AP mode,
the association fails. The former is using wpa_supplicant during association,
the later is set up using hostapd:
iwl$ cat hostapd.conf
interface=wlp1s0
ssid=test
country_code=DE
hw_mode=g
channel=1
wpa=2
wpa_passphrase=test
wpa_key_mgmt=WPA-PSK
iwl$ hostapd -d hostapd.conf
rsi$ wpa_supplicant -i wlan0 -c <(wpa_passphrase test test)
The problem is that the TX EAPOL data descriptor RSI_DESC_REQUIRE_CFM_TO_HOST
flag and extended descriptor EAPOL4_CONFIRM frame type are not set in case the
AP is iwlwifi, because in that case the TX EAPOL packet is 2 bytes shorter.
The downstream vendor driver has this change in place already [1], however
there is no explanation for it, neither is there any commit history from which
such explanation could be obtained.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Make sure to use the current alternate setting when verifying the
interface descriptors to avoid binding to an invalid interface.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

The driver expects at least one bulk-in endpoint when in "wifi-alone"
operating mode and two bulk-in endpoints otherwise, and would otherwise
fail to to submit the corresponding bulk URB to the default pipe during
probe with a somewhat cryptic message:
rsi_91x: rsi_rx_urb_submit: Failed in urb submission
rsi_91x: rsi_probe: Failed in probe...Exiting
RSI-USB WLAN: probe of 2-2.4:1.0 failed with error -8
The current endpoint sanity check looks broken and would only bail out
early if there was no bulk-in endpoint but at least one bulk-out
endpoint.
Tighten this check to always require at least one bulk-in and one
bulk-out endpoint, and add the missing sanity check for a Bluetooth
bulk-in endpoint when in a BT operating mode. Also make sure to log an
informative error message when the expected endpoints are missing.

The driver would fail to stop the command timer in most error paths,
something which specifically could lead to the timer being freed while
still active on I/O errors during probe.
Fix this by making sure that each function starting the timer also stops
it in all relevant error paths.
