58a96fc353 Bluetooth: Add debug setting for changing minimum encryption key size
For testing and qualification purposes it is useful to allow changing
the minimum encryption key size value that the host stack is going to
enforce. This adds a new debugfs setting min_encrypt_key_size to achieve
this functionality.

712042313b tipc: fix false detection of retransmit failures
This commit eliminates the use of the link 'stale_limit' & 'prev_from'
(besides the already removed - 'stale_cnt') variables in the detection
of repeated retransmit failures as there is no proper way to initialize
them to avoid a false detection, i.e. it is not really a retransmission
failure but due to a garbage values in the variables.

Instead, a jiffies variable will be added to individual skbs (like the
way we restrict the skb retransmissions) in order to mark the first skb
retransmit time. Later on, at the next retransmissions, the timestamp
will be checked to see if the skb in the link transmq is "too stale",
that is, the link tolerance time has passed, so that a link reset will
be ordered. Note, just checking on the first skb in the queue is fine
enough since it must be the oldest one.
A counter is also added to keep track the actual skb retransmissions'
number for later checking when the failure happens.

The downside of this approach is that the skb->cb[] buffer is about to
be exhausted, however it is always able to allocate another memory area
and keep a reference to it when needed.

Fixes: 77cf8edbc0 ("tipc: simplify stale link failure criteria")

b9cbf8a648 lan78xx: Fix memory leaks
In lan78xx_probe(), a new urb is allocated through usb_alloc_urb() and
saved to 'dev->urb_intr'. However, in the following execution, if an error
occurs, 'dev->urb_intr' is not deallocated, leading to memory leaks. To fix
this issue, invoke usb_free_urb() to free the allocated urb before
returning from the function.

b6143d10d2 arm64: ftrace: Ensure module ftrace trampoline is coherent with I-side
The initial support for dynamic ftrace trampolines in modules made use
of an indirect branch which loaded its target from the beginning of
a special section (e71a4e1beb ("arm64: ftrace: add support for far
branches to dynamic ftrace")). Since no instructions were being patched,
no cache maintenance was needed. However, later in be0f272bfc ("arm64:
ftrace: emit ftrace-mod.o contents through code") this code was reworked
to output the trampoline instructions directly into the PLT entry but,
unfortunately, the necessary cache maintenance was overlooked.

Add a call to __flush_icache_range() after writing the new trampoline
instructions but before patching in the branch to the trampoline.

a90118c445 x86/boot: Save fields explicitly, zero out everything else
Recent gcc compilers (gcc 9.1) generate warnings about an out of bounds
memset, if the memset goes accross several fields of a struct. This
generated a couple of warnings on x86_64 builds in sanitize_boot_params().

Fix this by explicitly saving the fields in struct boot_params
that are intended to be preserved, and zeroing all the rest.

[ tglx: Tagged for stable as it breaks the warning free build there as well ]

====================
rxrpc: Fix local endpoint handling

Here's a pair of patches that fix two issues in the handling of local
endpoints (rxrpc_local structs):

 (1) Use list_replace_init() rather than list_replace() if we're going to
     unconditionally delete the replaced item later, lest the list get
     corrupted.

 (2) Don't access the rxrpc_local object after passing our ref to the
     workqueue, not even to illuminate tracepoints, as the work function
     may cause the object to be freed.  We have to cache the information
     beforehand.

32d3182cd2 net/packet: fix race in tpacket_snd()
packet_sendmsg() checks tx_ring.pg_vec to decide
if it must call tpacket_snd().

Problem is that the check is lockless, meaning another thread
can issue a concurrent setsockopt(PACKET_TX_RING ) to flip
tx_ring.pg_vec back to NULL.

Given that tpacket_snd() grabs pg_vec_lock mutex, we can
perform the check again to solve the race.

19bce474c4 ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_term
`check_input_term` recursively calls itself with input from
device side (e.g., uac_input_terminal_descriptor.bCSourceID)
as argument (id). In `check_input_term`, if `check_input_term`
is called with the same `id` argument as the caller, it triggers
endless recursive call, resulting kernel space stack overflow.

This patch fixes the bug by adding a bitmap to `struct mixer_build`
to keep track of the checked ids and stop the execution if some id
has been checked (similar to how parse_audio_unit handles unitid
argument).

20fb7c7a39 net: myri10ge: fix memory leaks
In myri10ge_probe(), myri10ge_alloc_slices() is invoked to allocate slices
related structures. Later on, myri10ge_request_irq() is used to get an irq.
However, if this process fails, the allocated slices related structures are
not deallocated, leading to memory leaks. To fix this issue, revise the
target label of the goto statement to 'abort_with_slices'.

Fix the close path to only overwrite sk->sk_write_space when the current
pointer is to the tls_write_space function indicating the tls module should
clean it up properly as well.

f43d48d10a net/mlx5e: Fix compatibility issue with ethtool flash device
Cited patch deleted ethtool flash device support, as ethtool core can
fallback into devlink flash callback. However, this is supported only if
there is a devlink port registered over the corresponding netdevice.

As mlx5e do not have devlink port support over native netdevice, it broke
the ability to flash device via ethtool.

This patch re-add the ethtool callback to avoid user functionality breakage
when trying to flash device via ethtool.

revert the code and we'll try again with a thoroug solution. This
reverts commits:

e15c2ffa10 ("block: fix O_DIRECT error handling for bio fragments")
0eb6ddfb86 ("block: Fix __blkdev_direct_IO() for bio fragments")
6a43074e2f ("block: properly handle IOCB_NOWAIT for async O_DIRECT IO")

99c79f6692 io_uring: fix manual setup of iov_iter for fixed buffers
Commit bd11b3a391 ("io_uring: don't use iov_iter_advance() for fixed
buffers") introduced an optimization to avoid using the slow
iov_iter_advance by manually populating the iov_iter iterator in some
cases.

However, the computation of the iterator count field was erroneous: The
first bvec was always accounted for an extent of page size even if the
bvec length was smaller.

In consequence, some I/O operations on fixed buffers were unable to
operate on the full extent of the buffer, consistently skipping some
bytes at the end of it.

Fixes: bd11b3a391 ("io_uring: don't use iov_iter_advance() for fixed buffers")

edfbcb321f usb: add a hcd_uses_dma helper
The USB buffer allocation code is the only place in the usb core (and in
fact the whole kernel) that uses is_device_dma_capable, while the URB
mapping code uses the uses_dma flag in struct usb_bus.  Switch the buffer
allocation to use the uses_dma flag used by the rest of the USB code,
and create a helper in hcd.h that checks this flag as well as the
CONFIG_HAS_DMA to simplify the caller a bit.

If driver probe needs to be deferred, e.g. because ci_hdrc_add_device()
isn't ready yet, this driver currently misbehaves badly:
    a) success is still reported to the driver core (meaning a 2nd
       probe attempt will never be done), leaving the driver in
       a dysfunctional state and the hardware unusable

    b) driver remove / shutdown OOPSes:

    c) the error path in combination with driver removal causes
       imbalanced calls to the clk_*() and pm_()* APIs

a) happens because the original intended return value is
   overwritten (with 0) by the return code of
   regulator_disable() in ci_hdrc_imx_probe()'s error path
b) happens because ci_pdev is -EPROBE_DEFER, which causes
   ci_hdrc_remove_device() to OOPS

Fix a) by being more careful in ci_hdrc_imx_probe()'s error
path and not overwriting the real error code

Fix b) by calling the respective cleanup functions during
remove only when needed (when ci_pdev != NULL, i.e. when
everything was initialised correctly). This also has the
side effect of not causing imbalanced clk_*() and pm_*()
API calls as part of the error code path.

On Motorola Mapphone devices such as Droid 4 there are five USB ports
that do not use the same layout as Gobi 1K/2K/etc devices listed in
qcserial.c. So we should use qcaux.c or option.c as noted by

As the Motorola USB serial ports have an interrupt endpoint as shown
with lsusb -v, we should use option.c instead of qcaux.c as pointed out
by Johan Hovold <johan@kernel.org>.

The ff/ff/ff interfaces seem to always be UARTs on Motorola devices.
For the other interfaces, class 0x0a (CDC Data) should not in general
be added as they are typically part of a multi-interface function as
noted earlier by Bjørn Mork <bjorn@mork.no>.

However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a
class is only used for flashing the modem firmware, and there are no
other interfaces. So I've added that too with more details below as it
works just fine.

The ttyUSB ports on Droid 4 are:

ttyUSB0 DIAG, CQDM-capable
ttyUSB1 MUX or NMEA, no response
ttyUSB2 MUX or NMEA, no response
ttyUSB3 TCMD
ttyUSB4 AT-capable

The ttyUSB0 is detected as QCDM capable by ModemManager. I think
it's only used for debugging with ModemManager --debug for sending
custom AT commands though. ModemManager already can manage data
connection using the USB QMI ports that are already handled by the
qmi_wwan.c driver.

To enable the MUX or NMEA ports, it seems that something needs to be
done additionally to enable them, maybe via the DIAG or TCMD port.
It might be just a NVRAM setting somewhere, but I have no idea what
NVRAM settings may need changing for that.

The TCMD port seems to be a Motorola custom protocol for testing
the modem and to configure it's NVRAM and seems to work just fine
based on a quick test with a minimal tcmdrw tool I wrote.

The voice modem AT-capable port seems to provide only partial
support, and no PM support compared to the TS 27.010 based UART
wired directly to the modem.

The UARTs added with this change are the same product IDs as the
Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't
have any mdm9600 based devices, so I have only tested these on
mdm6600 based droid 4.

Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android
Linux kernel driver moto_flashqsc.c just seems to change the
port->bulk_out_size to 8K from the default. And is only used for
flashing the modem firmware it seems.

I've verified that flashing the modem with signed firmware works just
fine with the option driver after manually toggling the GPIO pins, so
I've added droid 4 modem flashing mode to the option driver. I've not
added the other devices listed in moto_flashqsc.c in case they really
need different port->bulk_out_size. Those can be added as they get
tested to work for flashing the modem.

After this patch the output of /sys/kernel/debug/usb/devices has
the following for normal 22b8:2a70 mode including the related qmi_wwan
interfaces:

db1231ddc0 drm/nouveau: Only recalculate PBN/VCPI on mode/connector changes
I -thought- I had fixed this entirely, but it looks like that I didn't
test this thoroughly enough as we apparently still make one big mistake
with nv50_msto_atomic_check() - we don't handle the following scenario:

* CRTC #1 has n VCPI allocated to it, is attached to connector DP-4
  which is attached to encoder #1. enabled=y active=n
* CRTC #1 is changed from DP-4 to DP-5, causing:
  * DP-4 crtc=#1→NULL (VCPI n→0)
  * DP-5 crtc=NULL→#1
  * CRTC #1 steals encoder #1 back from DP-4 and gives it to DP-5
  * CRTC #1 maintains the same mode as before, just with a different
    connector
* mode_changed=n connectors_changed=y
  (we _SHOULD_ do VCPI 0→n here, but don't)

Once the above scenario is repeated once, we'll attempt freeing VCPI
from the connector that we didn't allocate due to the connectors
changing, but the mode staying the same. Sigh.

Since nv50_msto_atomic_check() has broken a few times now, let's rethink
things a bit to be more careful: limit both VCPI/PBN allocations to
mode_changed || connectors_changed, since neither VCPI or PBN should
ever need to change outside of routing and mode changes.

Changes since v1:
* Fix accidental reversal of clock and bpp arguments in
  drm_dp_calc_pbn_mode() - William Lewis
