2.25.1
From: Nirenjan Krishnan <[email protected]>
[ Upstream commit 77df710ba633dfb6c65c65cf99ea9e084a1c9933 ]
The Saitek X52 family of joysticks has a pair of axes that were
originally (by the Windows driver) used as mouse pointer controls. The
corresponding usage page is the Game Controls page, which is not
recognized by the generic HID driver, and therefore, both axes get
mapped to ABS_MISC. The quirk makes the second axis get mapped to
ABS_MISC+1, and therefore made available separately.
One Saitek X52 device is already fixed. This patch fixes the other two
known devices with VID/PID 06a3:0255 and 06a3:0762.

2.25.1
From: Adam Ford <[email protected]>
[ Upstream commit 4d26e9a028e3d88223e06fa133c3d55af7ddbceb ]
Older versions of U-Boot would pinmux the whole board, but as
the bootloader got updated, it started to only pinmux the pins
it needed, and expected Linux to configure what it needed.
Unfortunately this caused an issue with the audio, because the
mcbsp2 pins were configured in the device tree but never
referenced by the driver. When U-Boot stopped muxing the audio
pins, the audio died.
This patch adds the references to the associate the pin controller
with the mcbsp2 driver which makes audio operate again.

commit 3f1093d83d7164e4705e4232ccf76da54adfda85 upstream.
Locking should be held for the entire reading sequence involving setting
the channel, waiting for the channel switch and reading from the
channel.
If not, reading from a channel can result mixing with the reading from
another channel.

It's writing too much data. regmap_bulk_write expects number of
register sized chunks to write, not a byte sized length of the
bounce buffer. Bounce buffer needs to be padded too, so that
regmap_bulk_write will not read past the end of the buffer.

The Tegra HDA codec HW implementation has an issue related to not
swapping the 2 channel Audio Sample Packet(ASP) channel mapping.
Whatever the FL and FR mapping specified the left channel always
comes out of left speaker and right channel on right speaker. So
add condition to disallow the swapping of FL,FR during the playback.

eznps driver is supposed to be platform independent however it ends up
including stuff from inside arch/arc headers leading to rand config
build errors.
The quick hack to fix this (proper fix is too much chrun for non active
user-base) is to add following to nps platform agnostic header.
- copy AUX_IENABLE from arch/arc header
- move CTOP_AUX_IACK from arch/arc/plat-eznps/*/**

[ Upstream commit cc5453a5b7e90c39f713091a7ebc53c1f87d1700 ]
If an sctp connection gets re-used, heartbeats are flagged as invalid
because their vtag doesn't match.
Handle this in a similar way as TCP conntrack when it suspects that the
endpoints and conntrack are out-of-sync.
When a HEARTBEAT request fails its vtag validation, flag this in the
conntrack state and accept the packet.
When a HEARTBEAT_ACK is received with an invalid vtag in the reverse
direction after we allowed such a HEARTBEAT through, assume we are
out-of-sync and re-set the vtag info.
v2: remove left-over snippet from an older incarnation that moved
new_state/old_state assignments, thats not needed so keep that
as-is.

commit e71e6dbe96ac80ac2aebe71a6a942e7bd60e7596 upstream.
To stop conversion ads1015_set_power_state() function call unimplemented
function __pm_runtime_suspend() from pm_runtime_put_autosuspend()
if CONFIG_PM is not set.
In case of CONFIG_PM is not set: __pm_runtime_suspend() returns -ENOSYS,
so ads1015_read_raw() failed because ads1015_set_power_state() returns an
error.
If CONFIG_PM is disabled, there is no need to start/stop conversion.
Fix it by adding return 0 function variant if CONFIG_PM is not set.

commit 2684d5003490df5398aeafe2592ba9d4a4653998 upstream.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
Here we use a structure on the stack. The driver already did an
explicit memset so no data leak was possible.
Forced alignment of ts is not strictly necessary but probably makes
the code slightly less fragile.
Note there has been some rework in this driver of the years, so no
way this will apply cleanly all the way back.

From: Jonathan Cameron <[email protected]>
commit a6f86f724394de3629da63fe5e1b7a4ab3396efe upstream.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses a 16 byte array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by moving
to a suitable structure in the iio_priv() data with alignment
ensured by use of an explicit c structure. This data is allocated
with kzalloc so no data can leak appart from previous readings.
Fixes tag is beyond some major refactoring so likely manual backporting
would be needed to get that far back.
Whilst the force alignment of the ts is not strictly necessary, it
does make the code less fragile.

Newer version of HSDK aka HSDK-4xD (with dual issue HS48x4 CPU) wired up
the perf interrupt, so enable that in DT.
This is OK for old HSDK where this irq is ignored because pct irq is not
wired up in hardware.

commit 2bb70f0a4b238323e4e2f392fc3ddeb5b7208c9e upstream.
The USB composition, defining the set of exported functions, is dynamic
in newer Quectel modems. Default functions can be disabled and
alternative functions can be enabled instead. The alternatives
includes class functions using interface pairs, which should be
handled by the respective class drivers.
Active interfaces are numbered consecutively, so static
blacklisting based on interface numbers will fail when the
composition changes. An example of such an error, where the
option driver has bound to the CDC ECM data interface,
preventing cdc_ether from handling this function:

Change rules for EC21, EC25, BG96 and EG95 to match vendor specific
serial functions only, to prevent binding to class functions. Require
2 endpoints on ff/ff/ff functions, avoiding the 3 endpoint QMI/RMNET
network functions.

commit cfd54fa83a5068b61b7eb28d3c117d8354c74c7a upstream.
Userspace drivers that use a SetConfiguration() request to "lightweight"
reset an already configured usb device might cause data toggles to get out
of sync between the device and host, and the device becomes unusable.
The xHCI host requires endpoints to be dropped and added back to reset the
toggle. If USB core notices the new configuration is the same as the
current active configuration it will avoid these extra steps by calling
usb_reset_configuration() instead of usb_set_configuration().
A SetConfiguration() request will reset the device side data toggles.
Make sure usb_reset_configuration() function also drops and adds back the
endpoints to ensure data toggles are in sync.
To avoid code duplication split the current usb_disable_device() function
and reuse the endpoint specific part.

[ Upstream commit 5110f40241d08334375eb0495f174b1d2c07657e ]
In the timeout handler we may need to complete a request because the
request that timed out may be an I/O that is a part of a serial sequence
of controller teardown or initialization. In order to complete the
request, we need to fence any other context that may compete with us
and complete the request that is timing out.
In this case, we could have a potential double completion in case
a hard-irq or a different competing context triggered error recovery
and is running inflight request cancellation concurrently with the
timeout handler.
Protect using a ctrl teardown_lock to serialize contexts that may
complete a cancelled request due to error recovery or a reset.

not been loaded yet.

commit afd55e6d1bd35b4b36847869011447a83a81c8e0 upstream.
There were some problem in ipq8074 Gen2 PCIe phy init sequence.
1. Few register values were wrongly updated in the phy init sequence.
2. The register QSERDES_RX_SIGDET_CNTRL is a RX tuning parameter
register which is added in serdes table causing the wrong register
was getting updated.
3. Clocks and resets were not added in the phy init.
Fix these to make Gen2 PCIe port on ipq8074 devices to work.

[ Upstream commit 13774d81f38538c5fa2924bdcdfa509155480fa6 ]
In snd_hdac_device_init pm_runtime_set_active is called to
increase child_count in parent device. But when it is failed
to build connection with GPU for one case that integrated
graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be
invoked to clean up a HD-audio extended codec base device. At
this time the child_count of parent is not decreased, which
makes parent device can't get suspended.
This patch calls pm_runtime_set_suspended to decrease child_count
in parent device in snd_hdac_device_exit to match with
snd_hdac_device_init. pm_runtime_set_suspended can make sure that
it will not decrease child_count if the device is already suspended.

From: Ilya Dryomov <[email protected]>
commit f44d04e696feaf13d192d942c4f14ad2e117065a upstream.
It turns out that currently we rely only on sysfs attribute
permissions:
$ ll /sys/bus/rbd/{add*,remove*}
--w------- 1 root root 4096 Sep 3 20:37 /sys/bus/rbd/add
--w------- 1 root root 4096 Sep 3 20:37 /sys/bus/rbd/add_single_major
--w------- 1 root root 4096 Sep 3 20:37 /sys/bus/rbd/remove
--w------- 1 root root 4096 Sep 3 20:38 /sys/bus/rbd/remove_single_major
This means that images can be mapped and unmapped (i.e. block devices
can be created and deleted) by a UID 0 process even after it drops all
privileges or by any process with CAP_DAC_OVERRIDE in its user namespace
as long as UID 0 is mapped into that user namespace.
Be consistent with other virtual block devices (loop, nbd, dm, md, etc)
and require CAP_SYS_ADMIN in the initial user namespace for mapping and
unmapping, and also for dumping the configuration string and refreshing
the image header.

commit 1ac698790819b83f39fd7ea4f6cdabee9bdd7b38 upstream.
These modules have 2 different USB layouts:
The default layout with PID 0x9205 (AT+CUSBSELNV=1) exposes 4 TTYs and
an ECM interface:

The purpose of each TTY is as follows:
* ttyUSB0: DIAG/QCDM port.
* ttyUSB1: GNSS data.
* ttyUSB2: AT-capable port (control).
* ttyUSB3: AT-capable port (data).
In the secondary layout with PID=0x9206 (AT+CUSBSELNV=86) the module
exposes 6 TTY ports:

From: Linus Torvalds <[email protected]>
commit 973c096f6a85e5b5f2a295126ba6928d9a6afd45 upstream.
Yunhai Zhang recently fixed a VGA software scrollback bug in commit
ebfdfeeae8c0 ("vgacon: Fix for missing check in scrollback handling"),
but that then made people look more closely at some of this code, and
there were more problems on the vgacon side, but also the fbcon software
scrollback.
We don't really have anybody who maintains this code - probably because
nobody actually _uses_ it any more. Sure, people still use both VGA and
the framebuffer consoles, but they are no longer the main user
interfaces to the kernel, and haven't been for decades, so these kinds
of extra features end up bitrotting and not really being used.
So rather than try to maintain a likely unused set of code, I'll just
aggressively remove it, and see if anybody even notices. Maybe there
are people who haven't jumped on the whole GUI badnwagon yet, and think
it's just a fad. And maybe those people use the scrollback code.
If that turns out to be the case, we can resurrect this again, once
we've found the sucker^Wmaintainer for it who actually uses it.

- help
- The scrollback buffer of the standard VGA console is located in
- the VGA RAM. The size of this RAM is fixed and is quite small.
- If you require a larger scrollback buffer, this can be placed in
- System RAM which is dynamically allocated during initialization.
- Placing the scrollback buffer in System RAM will slightly slow

- Say Y here if the scrollback history should persist by default when
- switching between consoles. Otherwise, the scrollback history will be
- flushed each time the console is switched. This feature can also be
- enabled using the boot command line parameter
- 'vgacon.scrollback_persistent=1'.
-
- This feature might break your tool of choice to flush the scrollback
- buffer, e.g. clear(1) will work fine but Debian's clear_console(1)
- will be broken, which might cause security issues.
- You can use the escape sequence \e[3J instead if this feature is
- activated.
-
- Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each
- created tty device.
- So if you use a RAM-constrained system, say N here.

commit 1dffeb8b8b4c261c45416d53c75ea51e6ece1770 upstream.
The current implementation for gbcodec_mixer_dapm_ctl_put() uses
uninitialized gbvalue for comparison with updated value. This was found
using static analysis with coverity.
Uninitialized scalar variable (UNINIT)
11. uninit_use: Using uninitialized value
gbvalue.value.integer_value[0].
460 if (gbvalue.value.integer_value[0] != val) {
This patch fixes the issue with fetching the gbvalue before using it for
comparision.

[ Upstream commit eacc9c5a927e474c173a5d53dd7fb8e306511768 ]
This fixes the behavior of the scaling_max_freq and scaling_min_freq
sysfs files in systems which had turbo disabled by the BIOS.
Caleb noticed that the HWP is programmed to operate in the wrong
P-state range on his system when the CPUFREQ policy min/max frequency
is set via sysfs. This seems to be because in his system
intel_pstate_get_hwp_max() is returning the maximum turbo P-state even
though turbo was disabled by the BIOS, which causes intel_pstate to
scale kHz frequencies incorrectly e.g. setting the maximum turbo
frequency whenever the maximum guaranteed frequency is requested via
sysfs.

On my R9 390, the voltage was reported as a constant 1000 mV.
This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor()
function, where some magic constants were used in a condition,
to determine whether the voltage should be read from PLANE2_VID
or PLANE1_VID. The VDDC mask was incorrectly used, instead of
the VDDGFX mask.
This patch changes the code to use the correct defined constants
(and apply the correct bitshift), thus resulting in correct voltage reporting.

After commit f6ebbcf08f37 ("cpufreq: intel_pstate: Implement passive
mode with HWP enabled") it is possible to change the driver status
to "off" via sysfs with HWP enabled, which effectively causes the
driver to unregister itself, but HWP remains active and it forces the
minimum performance, so even if another cpufreq driver is loaded,
it will not be able to control the CPU frequency.
For this reason, make the driver refuse to change the status to
"off" with HWP enabled.

HSDK board has Micrel KSZ9031, recent commit
bcf3440c6dd ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY")
caused a breakdown of Ethernet.
Using 'phy-mode = "rgmii"' is not correct because accodring RGMII
specification it is necessary to have delay on RX (PHY to MAX)
which is not generated in case of "rgmii".
Using "rgmii-id" adds necessary delay and solves the issue.
Also adding name of PHY placed on HSDK board.

commit 1c78544eaa4660096aeb6a57ec82b42cdb3bfe5a upstream.
When faulting in the pages for the user supplied buffer for the search
ioctl, we are passing only the base address of the buffer to the function
fault_in_pages_writeable(). This means that after the first iteration of
the while loop that searches for leaves, when we have a non-zero offset,
stored in 'sk_offset', we try to fault in a wrong page range.
So fix this by adding the offset in 'sk_offset' to the base address of the
user supplied buffer when calling fault_in_pages_writeable().
Several users have reported that the applications compsize and bees have
started to operate incorrectly since commit a48b73eca4ceb9 ("btrfs: fix
potential deadlock in the search ioctl") was added to stable trees, and
these applications make heavy use of the search ioctls. This fixes their
issues.

commit eb1a148ef41d8ae8d9201efc3f1b145976290331 upstream.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data with alignment
explicitly requested. This data is allocated with kzalloc so no
data can leak appart from previous readings.
The explicit alignment of ts is necessary to ensure consistent
padding for x86_32 in which the ts would otherwise be 4 byte aligned.

[ Upstream commit 53de092f47ff40e8d4d78d590d95819d391bf2e0 ]
It was discovered that sdparm will fail when attempting to disable write
cache on a SATA disk connected via libsas.
In the ATA command set the write cache state is controlled through the SET
FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and
the latter command is what is used in the SCSI-ATA translation layer. A
subtle difference is that a MODE SELECT carries data whereas SET FEATURES
is defined as a non-data command in ATA.
Set the DMA data direction to DMA_NONE if the requested ATA command is
identified as non-data.

2.25.1
From: Adam Ford <[email protected]>
[ Upstream commit d7dfee67688ac7f2dfd4c3bc70c053ee990c40b5 ]
Older versions of U-Boot would pinmux the whole board, but as
the bootloader got updated, it started to only pinmux the pins
it needed, and expected Linux to configure what it needed.
Unfortunately this caused an issue with the audio, because the
mcbsp2 pins were configured in the device tree, they were never
referenced by the driver. When U-Boot stopped muxing the audio
pins, the audio died.
This patch adds the references to the associate the pin controller
with the mcbsp2 driver which makes audio operate again.

2.25.1
From: Jonathan Cameron <[email protected]>
commit 02ad21cefbac4d89ac443866f25b90449527737b upstream.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart from
previous readings.
The explicit alignment of ts is not necessary in this case as by
coincidence the padding will end up the same, however I consider
it to make the code less fragile and have included it.

[ Upstream commit 9d5dcefb7b114d610aeb2371f6a6f119af316e43 ]
As the comments in this patch say, if we tune and find all phases are
valid it's _almost_ as bad as no phases being found valid. Probably
all phases are not really reliable but we didn't detect where the
unreliable place is. That means we'll essentially be guessing and
hoping we get a good phase.
This is not just a problem in theory. It was causing real problems on
a real board. On that board, most often phase 10 is found as the only
invalid phase, though sometimes 10 and 11 are invalid and sometimes
just 11. Some percentage of the time, however, all phases are found
to be valid. When this happens, the current logic will decide to use
phase 11. Since phase 11 is sometimes found to be invalid, this is a
bad choice. Sure enough, when phase 11 is picked we often get mmc
errors later in boot.
I have seen cases where all phases were found to be valid 3 times in a
row, so increase the retry count to 10 just to be extra sure.

This driver didn't set hard_header_len. This patch sets hard_header_len
for it according to its header_ops->create function.
This driver's header_ops->create function (cisco_hard_header) creates
a header of (struct hdlc_header), so hard_header_len should be set to
sizeof(struct hdlc_header).

Well, 3f1093d83d71 is only applied later in the stable series, so this
introduces spurious unlock.
Ideally this should go just after 3f1093d83d71 ("iio: adc: mcp3422:
fix locking scope").

This does not fix any bug and is not needed in 4.19-stable. In the
5.8-stable there are other patches that depend on that (which is
probably why it was merged), but those are not present in 4.19.
Please drop.

CIP testing did not find any kernel problems:
