In commit 8930a6c20791 ("scsi: core: add support for request batching") the
block layer bd->last flag was mapped to SCMD_LAST and used as an indicator
to send the batch for the drivers that implement this feature. However, the
error handling code was not updated accordingly.
scsi_send_eh_cmnd() is used to send error handling commands and request
sense. The problem is that request sense comes as a single command that
gets into the batch queue and times out. As a result the device goes
offline after several failed resets. This was observed on virtio_scsi
during a device resize operation.

Here "temp" is the number of characters that we have written and "size"
is the size of the buffer. The intent was clearly to say that if we have
written to the end of the buffer then stop.
However, for that to work the comparison should have been done on the
original "size" value instead of the "size -= temp" value. Not only
will that not trigger when we want to, but there is a small chance that
it will trigger incorrectly before we want it to and we break from the
loop slightly earlier than intended.
This code was recently changed from using snprintf() to scnprintf(). With
snprintf() we likely would have continued looping and passed a negative
size parameter to snprintf(). This would have triggered an annoying
WARN(). Now that we have converted to scnprintf() "size" will never
drop below 1 and there is no real need for this test. We could change
the condition to "if (temp <= 1) goto done;" but just deleting the test
is cleanest.

commit 3dc5d44545453de1de9c53cc529cc960a85933da upstream.
There is a bug in the ks8851 Ethernet driver that more data is written
to the hardware TX buffer than actually available. This is caused by
wrong accounting of the free TX buffer space.
The driver maintains a tx_space variable that represents the TX buffer
space that is deemed to be free. The ks8851_start_xmit_spi() function
adds an SKB to a queue if tx_space is large enough and reduces tx_space
by the amount of buffer space it will later need in the TX buffer and
then schedules a work item. If there is not enough space then the TX
queue is stopped.
The worker function ks8851_tx_work() dequeues all the SKBs and writes
the data into the hardware TX buffer. The last packet will trigger an
interrupt after it was send. Here it is assumed that all data fits into
the TX buffer.
In the interrupt routine (which runs asynchronously because it is a
threaded interrupt) tx_space is updated with the current value from the
hardware. Also the TX queue is woken up again.
Now it could happen that after data was sent to the hardware and before
handling the TX interrupt new data is queued in ks8851_start_xmit_spi()
when the TX buffer space had still some space left. When the interrupt
is actually handled tx_space is updated from the hardware but now we
already have new SKBs queued that have not been written to the hardware
TX buffer yet. Since tx_space has been overwritten by the value from the
hardware the space is not accounted for.
Now we have more data queued then buffer space available in the hardware
and ks8851_tx_work() will potentially overrun the hardware TX buffer. In
many cases it will still work because often the buffer is written out
fast enough so that no overrun occurs but for example if the peer
throttles us via flow control then an overrun may happen.
This can be fixed in different ways. The most simple way would be to set
tx_space to 0 before writing data to the hardware TX buffer preventing
the queuing of more SKBs until the TX interrupt has been handled. I have
chosen a slightly more efficient (and still rather simple) way and
track the amount of data that is already queued and not yet written to
the hardware. When new SKBs are to be queued the already queued amount
of data is honoured when checking free TX buffer space.
I tested this with a setup of two linked KS8851 running iperf3 between
the two in bidirectional mode. Before the fix I got a stall after some
minutes. With the fix I saw now issues anymore after hours.

commit 54cf39ec16335dadbe1ba008d8e5e98dae3e26f8 upstream.
The HTU21 offers 4 sampling frequencies: 20, 40, 70 and 120, which are
associated to an index that is used to select the right measurement
resolution and its corresponding measurement time. The current
implementation selects the measurement resolution and the temperature
measurement time properly, but it does not select the right humidity
measurement time in all cases.
In summary, the 40 and 70 humidity measurement times are swapped.
The reason for that is probably the unusual coding for the measurement
resolution. According to the datasheet, the bits [7,0] of the "user
register" are used as follows to select the bit resolution:
--------------------------------------------------
| Bit 7 | Bit 0 | RH | Temp | Trh (us) | Tt (us) |
--------------------------------------------------
| 0 | 0 | 12 | 14 | 16000 | 50000 |
--------------------------------------------------
| 0 | 1 | 8 | 12 | 3000 | 13000 |
--------------------------------------------------
| 1 | 0 | 10 | 13 | 5000 | 25000 |
--------------------------------------------------
| 1 | 1 | 11 | 11 | 8000 | 7000 |
--------------------------------------------------
*This table is available in the official datasheet, page 13/21. I have
just appended the times provided in the humidity/temperature tables,
pages 3/21, 5/21. Note that always a pair of resolutions is selected.
The sampling frequencies [20, 40, 70, 120] are assigned to a linear
index [0..3] which is then coded as follows [1]:
Index [7,0]
--------------
idx 0 0,0
idx 1 1,0
idx 2 0,1
idx 3 1,1
That is done that way because the temperature measurements are being
used as the reference for the sampling frequency (the frequencies and
the temperature measurement times are correlated), so increasing the
index always reduces the temperature measurement time and its
resolution. Therefore, the temperature measurement time array is as
simple as [50000, 25000, 13000, 7000]
On the other hand, the humidity resolution cannot follow the same
pattern because of the way it is coded in the "user register", where
both resolutions are selected at the same time. The humidity measurement
time array is the following: [16000, 3000, 5000, 8000], which defines
the following assignments:
Index [7,0] Trh
-----------------------
idx 0 0,0 16000 -> right, [0,0] selects 12 bits (Trh = 16000)
idx 1 1,0 3000 -> wrong! [1,0] selects 10 bits (Trh = 5000)
idx 2 0,1 5000 -> wrong! [0,1] selects 8 bits (Trh = 3000)
idx 3 1,1 8000 -> right, [1,1] selects 11 bits (Trh = 8000)
The times have been ordered as if idx = 1 -> [0,1] and idx = 2 -> [1,0],
which is not the case for the reason explained above.
So a simple modification is required to obtain the right humidity
measurement time array, swapping the values in the positions 1 and 2.
The right table should be the following: [16000, 5000, 3000, 8000]
Fix the humidity measurement time array with the right idex/value
coding.
[1] The actual code that makes this coding and assigns it to the current
value of the "user register" is the following:
config_reg &= 0x7E;
config_reg |= ((i & 1) << 7) + ((i & 2) >> 1);

This warning is raised because pinctrl-at91-pio4 uses chained IRQ. Whenever
a wake up source configures an IRQ through irq_set_irq_wake, it will
lock the corresponding IRQ desc, and then call irq_set_irq_wake on "parent"
IRQ which will do the same on its own IRQ desc, but since those two locks
share the same class, lockdep reports this as an issue.
Fix lockdep false positive by setting a different class for parent and
children IRQ

commit f16c6d2e58a4c2b972efcf9eb12390ee0ba3befb upstream
A null pointer dereference can happen when attempting to access the
"gsm->receive()" function in gsmld_receive_buf(). Currently, the code
assumes that gsm->receive is only called after MUX activation.
Since the gsmld_receive_buf() function can be accessed without the need to
initialize the MUX, the gsm->receive() function will not be set and a
NULL pointer dereference will occur.
Fix this by avoiding the call to "gsm->receive()" in case the function is
not initialized by adding a sanity check.

commit 01aecd917114577c423f07cec0d186ad007d76fc upstream.
The current implementation registers/deregisters the user ttys at mux
attach/detach. That means that the user devices are available before any
control channel is open. However, user channel initialization requires an
open control channel. Furthermore, the user is not informed if the mux
restarts due to configuration changes.
Put the registration/deregistration procedure into separate function to
improve readability.
Move registration to mux activation and deregistration to mux cleanup to
keep the user devices only open as long as a control channel exists. The
user will be informed via the device driver if the mux was reconfigured in
a way that required a mux re-activation.
This makes it necessary to add T2 initialization to gsmld_open() for the
ldisc open code path (not the reconfiguration code path) to avoid deletion
of an uninitialized T2 at mux cleanup.

commit c12296bbecc488623b7d1932080e394d08f3226b upstream.
In __team_options_register, team_options are allocated and appended to
the team's option_list.
If one option instance allocation fails, the "inst_rollback" cleanup
path frees the previously allocated options but doesn't remove them from
the team's option_list.
This leaves dangling pointers that can be dereferenced later by other
parts of the team driver that iterate over options.
This patch fixes the cleanup path to remove the dangling pointers from
the list.
As far as I can tell, this uaf doesn't have much security implications
since it would be fairly hard to exploit (an attacker would need to make
the allocation of that specific small object fail) but it's still nice
to fix.

The Glorious Model I mouse has a buggy HID report descriptor for its
keyboard endpoint (used for programmable buttons). For report ID 2, there
is a mismatch between Logical Minimum and Usage Minimum in the array that
reports keycodes.
The offending portion of the descriptor: (from hid-decode)
0x95, 0x05, // Report Count (5) 30
0x75, 0x08, // Report Size (8) 32
0x15, 0x00, // Logical Minimum (0) 34
0x25, 0x65, // Logical Maximum (101) 36
0x05, 0x07, // Usage Page (Keyboard) 38
0x19, 0x01, // Usage Minimum (1) 40
0x29, 0x65, // Usage Maximum (101) 42
0x81, 0x00, // Input (Data,Arr,Abs) 44
This bug shifts all programmed keycodes up by 1. Importantly, this causes
"empty" array indexes of 0x00 to be interpreted as 0x01, ErrorRollOver.
The presence of ErrorRollOver causes the system to ignore all keypresses
from the endpoint and breaks the ability to use the programmable buttons.
Setting byte 41 to 0x00 fixes this, and causes keycodes to be interpreted
correctly.
Also, USB_VENDOR_ID_GLORIOUS is changed to USB_VENDOR_ID_SINOWEALTH,
and a new ID for Laview Technology is added. Glorious seems to be
white-labeling controller boards or mice from these vendors. There isn't a

[ Upstream commit baf8fb7e0e5ec54ea0839f0c534f2cdcd79bea9c ]
Arraies bcache->stripe_sectors_dirty and bcache->full_dirty_stripes are
used for dirty data writeback, their sizes are decided by backing device
capacity and stripe size. Larger backing device capacity or smaller
stripe size make these two arraies occupies more dynamic memory space.
Currently bcache->stripe_size is directly inherited from
queue->limits.io_opt of underlying storage device. For normal hard
drives, its limits.io_opt is 0, and bcache sets the corresponding
stripe_size to 1TB (1<<31 sectors), it works fine 10+ years. But for
devices do declare value for queue->limits.io_opt, small stripe_size
(comparing to 1TB) becomes an issue for oversize memory allocations of
bcache->stripe_sectors_dirty and bcache->full_dirty_stripes, while the
capacity of hard drives gets much larger in recent decade.
For example a raid5 array assembled by three 20TB hardrives, the raid
device capacity is 40TB with typical 512KB limits.io_opt. After the math
calculation in bcache code, these two arraies will occupy 400MB dynamic
memory. Even worse Andrea Tomassetti reports that a 4KB limits.io_opt is
declared on a new 2TB hard drive, then these two arraies request 2GB and
512MB dynamic memory from kzalloc(). The result is that bcache device
always fails to initialize on his system.
To avoid the oversize memory allocation, bcache->stripe_size should not
directly inherited by queue->limits.io_opt from the underlying device.
This patch defines BCH_MIN_STRIPE_SZ (4MB) as minimal bcache stripe size
and set bcache device's stripe size against the declared limits.io_opt
value from the underlying storage device,
- If the declared limits.io_opt > BCH_MIN_STRIPE_SZ, bcache device will
set its stripe size directly by this limits.io_opt value.
- If the declared limits.io_opt < BCH_MIN_STRIPE_SZ, bcache device will
set its stripe size by a value multiplying limits.io_opt and euqal or
large than BCH_MIN_STRIPE_SZ.
Then the minimal stripe size of a bcache device will always be >= 4MB.
For a 40TB raid5 device with 512KB limits.io_opt, memory occupied by
bcache->stripe_sectors_dirty and bcache->full_dirty_stripes will be 50MB
in total. For a 2TB hard drive with 4KB limits.io_opt, memory occupied
by these two arraies will be 2.5MB in total.
Such mount of memory allocated for bcache->stripe_sectors_dirty and
bcache->full_dirty_stripes is reasonable for most of storage devices.

[ Upstream commit ccab434e674ca95d483788b1895a70c21b7f016a ]
If a device sends a packet that is inbetween 0
and sizeof(u64) the value passed to skb_trim()
as length will wrap around ending up as some very
large value.
The driver will then proceed to parse the header
located at that position, which will either oops or
process some random value.
The fix is to check against sizeof(u64) rather than
0, which the driver currently does. The issue exists
since the introduction of the driver.
