commit 3c0e25d883d06a1fbd1ad35257e8abaa57befb37 upstream.
Make sure to detect short control-message transfers and log an error
when reading incomplete manufacturer and boot descriptors.
Note that the default all-zero descriptors will now be used after a
short transfer is detected instead of partially initialised ones.

commit 36356a669eddb32917fc4b5c2b9b8bf80ede69de upstream.
Make sure to detect short control-message transfers so that errors are
logged when reading the modem status at open.
Note that while this also avoids initialising the modem status using
uninitialised heap data, these bits could not leak to user space as they
are currently not used.

This specifically makes sure that an errno is returned to user space on

We're currently emulating the vbus and id interrupts in the OTGSC
read API, but we also need to make sure that if we're handling
the events with extcon that we don't enable the interrupts for

register if we're using extcon, but don't enable the interrupts.
This allows me to get my cable connect/disconnect working

When driver needs to access the contents of a streaming DMA buffer
without unmapping it it should call dma_sync_single_for_cpu().
Once the call has been made, the CPU "owns" the DMA buffer and can
work with it as needed.
Before the device accesses the buffer, however, ownership should be
transferred back to it with dma_sync_single_for_device().
Both calls weren't performed by the driver, resulting with odd paging
errors on some platforms. Fix it.

commit c56108b58ab870892277940a1def0d6b153f3e26 upstream.
In DQA mode, first_agg_queue is initialized to
IWL_MVM_DQA_MIN_DATA_QUEUE. This causes two bugs in the tx response
flow:
1. When TX fails, we set IEEE80211_TX_STAT_AMPDU_NO_BACK regardless
if we actually have aggregation open on the queue. This causes
mac80211 to send a BAR frame even though there is no aggregation
open.
Fix that by simply checking the AMPDU flag that is set on by
mac80211 for AMPDU packets.
2. When reclaiming frames in aggregation mode, we reclaim based on
scheduler ssn and not the SN.
The reason is that scheduler ssn may be ahead of SN due to a hole
in the BA window that was filled.
However, if we have aggregations open on IWL_MVM_DQA_BSS_CLIENT_QUEUE
the reclaim flow will still go to the code of non-aggregation
instead of the aggregation code since IWL_MVM_DQA_BSS_CLIENT_QUEUE
is smaller than IWL_MVM_DQA_MIN_DATA_QUEUE, although it is a valid
aggregation queue.
Fix that by always using the aggregation reclaim code by default in
DQA mode (currently it is implicitly used by default for all queues
except the reserved BSS queue).

commit 94c3e614df2117626fccfac8f821c66e30556384 upstream.
In DQA mode the check whether to decrement the pending frames
counter relies on the tid status and not on the txq id.
This may result in an inconsistent state of the pending frames
counter in case frame is queued on a non aggregation queue but
with this TID, and will be followed by a failure to remove the
station and later on SYSASSERT 0x3421 when trying to remove the
MAC.
Such frames are for example bar and qos NDPs.
Fix it by aligning the condition of incrementing the counter
with the condition of decrementing it - rely on TID state for
DQA mode.
Also, avoid internal error like this affecting station removal
for DQA mode - since we can know for sure it is an internal
error.

commit 05e5a7e58d3f8f597ebe6f78aaa13a2656b78239 upstream.
Instead of setting the tx_cmd length in the mvm code, which is
complicated by the fact that DQA may want to temporarily store
the SKB on the side, adjust the length in the PCIe code which
also knows about this since it's responsible for duplicating
all those headers that are account for in this code.
As the PCIe code already relies on the tx_cmd->len field, this
doesn't really introduce any new dependencies.
To make this possible we need to move the memcpy() of the TX
command until after it was updated.
This does even simplify the code though, since the PCIe code
already does a lot of manipulations to build A-MSDUs correctly
and changing the length becomes a simple operation to see how
much was added/removed, rather than predicting it.

commit bd05a5bd6b11d7fd26a668de83c5cb996de05f8f upstream.
We don't really need clear the skb's status area nor store the
dev_cmd into it until we really commit to the frame by handing
it to the transport - defer those operations until just before
we do that.
This doesn't entirely fix the bug with frames not getting sent
out after having been deferred due to DQA, because it doesn't
restore the info->driver_data[0] place that was already set to
zero (or another value) by the A-MSDU logic.

commit a5b60de6972decc6b50a39abb376077c3c3621c8 upstream.
This patch fixes the issue specific to AP. AP is started with WEP
security and external station is connected to it. Data path works
in this case. Now if AP is restarted with WPA/WPA2 security,
station is able to connect but ping fails.
Driver skips the deletion of WEP keys if interface type is AP.
Removing that redundant check resolves the issue.

commit 6183468a23fc6b6903f8597982017ad2c7fdefcf upstream.
Similar to commit fcd2042e8d36 ("mwifiex: printk() overflow with 32-byte
SSIDs"), we failed to account for the existence of 32-char SSIDs in our
debugfs code. Unlike in that case though, we zeroed out the containing
struct first, and I'm pretty sure we're guaranteed to have some padding
after the 'ssid.ssid' and 'ssid.ssid_len' fields (the struct is 33 bytes
long).
So, this is the difference between:
# cat /sys/kernel/debug/mwifiex/mlan0/info
...
essid="0123456789abcdef0123456789abcdef "
...
and the correct output:
# cat /sys/kernel/debug/mwifiex/mlan0/info
...
essid="0123456789abcdef0123456789abcdef"
...

The CPU port of the BCM53125 is configured with RGMII (no delays) but
this should actually be RGMII with transmit delay (rgmii-txid) because
STMMAC takes care of inserting the transmitter delay. This fixes
occasional packet loss encountered.

commit cbe99c538d1776009e8710755bb6e726f7fffa9b upstream.
gcc gets confused about the control flow in ktd2692_parse_dt(), causing
it to warn about what seems like a potential bug:
drivers/leds/leds-ktd2692.c: In function 'ktd2692_probe':
drivers/leds/leds-ktd2692.c:244:15: error: '*((void *)&led_cfg+8)' may be used uninitialized in this function [-Werror=maybe-uninitialized]

drivers/leds/leds-ktd2692.c:232:3: error: 'led_cfg.movie_max_microamp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The code is fine, and slightly reworking it in an equivalent way lets
gcc figure that out too, which gets rid of the warning.

commit ec663d967b2276448a416406ca59ff247c0c80c5 upstream.
Commit cab15ce604e5 ("arm64: Introduce execute-only page access
permissions") allowed a valid user PTE to have the PTE_USER bit clear.
As a consequence, the pte_valid_not_user() macro in set_pte() was
replaced with pte_valid_global() under the assumption that only user
pages have the nG bit set. EFI mappings, however, also have the nG bit
set and set_pte() wrongly ignores issuing the DSB+ISB.
This patch reinstates the pte_valid_not_user() macro and adds the
PTE_UXN bit check since all kernel mappings have this bit set. For
clarity, pte_exec() is renamed to pte_user_exec() as it only checks for
the absence of PTE_UXN. Consequently, the user executable check in
set_pte_at() drops the pte_ng() test since pte_user_exec() is
sufficient.

commit 68abfb8015832ddf728b911769659468efaf8bd9 upstream.
Caching the fault register after a single I2C read may not keep an accurate
value.
Fix by doing two reads in irq_handle_thread() and using the cached value
elsewhere. If a safety timer fault later clears itself, we apparently don't get
an interrupt (INT), however other interrupts would refresh the register cache.
From the data sheet: "When a fault occurs, the charger device sends out INT
and keeps the fault state in REG09 until the host reads the fault register.
Before the host reads REG09 and all the faults are cleared, the charger
device would not send any INT upon new faults. In order to read the
current fault status, the host has to read REG09 two times consecutively.
The 1st reads fault register status from the last read [1] and the 2nd reads
the current fault register status."
[1] presumably a typo; should be "last fault"
