This driver adds support for Silead touchscreens. It has been tested
with GSL1680 and GSL3680 touch panels.
It supports ACPI and device tree enumeration. Screen resolution,
the maximum number of fingers supported and firmware name are
configurable.

Input: silead - remove some dead code
buf[0] is an unsigned char. touch_nr is an int. The test for negative
here doesn't make sense so I have removed it.

Input: silead - use devm_gpiod_get
The silead code is using devm_foo for everything (and does not free
any resources). Except that it is using gpiod_get instead of
devm_gpiod_get (but is not freeing the gpio_desc), change this
to use devm_gpiod_get so that the gpio will be properly released.

Input: silead_gsl1680 - document firmware-name, fix implementation
The driver has supported touchscreen-fw-name to specify the firmware to
load since it has been merged, but this was omitted from the dt-binding
documentation.
During review of adding touchscreen-fw-name to the binding documentation
it was brought up that there is a standard property name called
"firmware-name" for this, which should be used.
Since there are no users of touchscreen-fw-name yet, this commit
adds documentation of "firmware-name" to the dt-binding documentation
and switches the driver over to use this.
This commit also makes the driver add a "silead/" prefix to the
firmware name from dt before calling request_firmware. That the
firmware files are stored under /lib/firmware/silead under Linux
is an implementation detail and does not belong in devicetree.

Input: silead_gsl1680 - use "silead/" prefix for firmware loading
The silead touch-controller ICs use a different firmware per digitizer /
tablet model. So there are going to be quite a few of then and they really
should be under a separate subdir.
This commit prefixes the default firmware names with "silead/" just like
we are already doing for devicetree specified firmware names.

Input: silead - add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
As pointed by Hans de Goede, there's no mssl1680 and this is just used in
some ACPI systems to identify the gsl1680 chip. So isn't included in the
OF device ID table since a DT should use the proper device name instead.

Input: silead: retry firmware load
If we get ENOENT when trying to load the firmware, this can just mean
that the rootfs is not mounted yet. Return EPROBE_DEFER so the probe
is retried later.
To prevent an infinite probe loop when the firmware does not exist at
all, the retries are capped to 10.

The early (RK_EXCAVATOR_MAIN_V10_20160627) v10 board had some hardware
issues, for example, pwm regulator even a small miscalculation by hardware
and the emmc can't work on hs400 mode. But there still have someone used
the old v10 boards on their hands.
Anyway, that should support the old v10 board with this patch.

[ Upstream commit de9c0d49d85dc563549972edc5589d195cd5e859 ]
While building arm32 allyesconfig, I ran into the following errors:
arch/arm/lib/xor-neon.c:17:2: error: You should compile this file with
'-mfloat-abi=softfp -mfpu=neon'
In file included from lib/raid6/neon1.c:27:
/home/nathan/cbl/prebuilt/lib/clang/8.0.0/include/arm_neon.h:28:2:
error: "NEON support not enabled"
Building V=1 showed NEON_FLAGS getting passed along to Clang but
__ARM_NEON__ was not getting defined. Ultimately, it boils down to Clang
only defining __ARM_NEON__ when targeting armv7, rather than armv6k,
which is the '-march' value for allyesconfig.
>From lib/Basic/Targets/ARM.cpp in the Clang source:
// This only gets set when Neon instructions are actually available, unlike
// the VFP define, hence the soft float and arch check. This is subtly
// different from gcc, we follow the intent which was that it should be set
// when Neon instructions are actually available.
if ((FPU & NeonFPU) && !SoftFloat && ArchVersion >= 7) {
Builder.defineMacro("__ARM_NEON", "1");
Builder.defineMacro("__ARM_NEON__");
// current AArch32 NEON implementations do not support double-precision
// floating-point even when it is present in VFP.
Builder.defineMacro("__ARM_NEON_FP",
"0x" + Twine::utohexstr(HW_FP & ~HW_FP_DP));
}
Ard Biesheuvel recommended explicitly adding '-march=armv7-a' at the
beginning of the NEON_FLAGS definitions so that __ARM_NEON__ always gets
definined by Clang. This doesn't functionally change anything because
that code will only run where NEON is supported, which is implicitly
armv7.

commit ddba91801aeb5c160b660caed1800eb3aef403f8 upstream.
KVM's API requires thats ioctls must be issued from the same process
that created the VM. In other words, userspace can play games with a
VM's file descriptors, e.g. fork(), SCM_RIGHTS, etc..., but only the
creator can do anything useful. Explicitly reject device ioctls that
are issued by a process other than the VM's creator, and update KVM's
API documentation to extend its requirements to device ioctls.

This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.
Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card
f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.
f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.
f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.
Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.
Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.
g_audio can be built using one of existing
UAC functions (f_uac1, f_uac1_legacy or f_uac2)

There are only two requests for uac2, it may not be enough at high
loading system which usb interrupt handler can't be serviced on
time, then the data will be lost since it is isoc transfer for audio.
In this patch, we introduce a parameter for the number for usb request,
and the user can override it if current number for request is not enough
for his/her use case.
Besides, update this parameter for legacy audio gadget and documentation.

By default, all access to the upper, lower and work directories is the
recorded mounter's MAC and DAC credentials. The incoming accesses are
checked against the caller's credentials.
If the principles of least privilege are applied, the mounter's
credentials might not overlap the credentials of the caller's when
accessing the overlayfs filesystem. For example, a file that a lower
DAC privileged caller can execute, is MAC denied to the generally
higher DAC privileged mounter, to prevent an attack vector.
We add the option to turn off override_creds in the mount options; all
subsequent operations after mount on the filesystem will be only the
caller's credentials. The module boolean parameter and mount option
override_creds is also added as a presence check for this "feature",
existence of /sys/module/overlay/parameters/override_creds.
It was not always this way. Circa 4.6 there was no recorded mounter's
credentials, instead privileged access to upper or work directories
were temporarily increased to perform the operations. The MAC
(selinux) policies were caller's in all cases. override_creds=off
partially returns us to this older access model minus the insecure
temporary credential increases. This is to permit use in a system
with non-overlapping security models for each executable including
the agent that mounts the overlayfs filesystem. In Android
this is the case since init, which performs the mount operations,
has a minimal MAC set of privileges to reduce any attack surface,
and services that use the content have a different set of MAC
privileges (eg: read, for vendor labelled configuration, execute for
vendor libraries and modules). The caveats are not a problem in
the Android usage model, however they should be fixed for
completeness and for general use in time.

commit 3e67f106f619dcfaf6f4e2039599bdb69848c714 upstream.
Some users are willing to provision huge amounts of memory to be able
to perform reassembly reasonnably well under pressure.
Current memory tracking is using one atomic_t and integers.
Switch to atomic_long_t so that 64bit arches can use more than 2GB,
without any cost for 32bit arches.
Note that this patch avoids an overflow error, if high_thresh was set
to ~2GB, since this test in inet_frag_alloc() was never true :
if (... || frag_mem_limit(nf) > nf->high_thresh)
Tested:
$ echo 16000000000 >/proc/sys/net/ipv4/ipfrag_high_thresh
<frag DDOS>
$ grep FRAG /proc/net/sockstat
FRAG: inuse 14705885 memory 16000002880
$ nstat -n ; sleep 1 ; nstat | grep Reas

commit 648700f76b03b7e8149d13cc2bdb3355035258a9 upstream.
Some applications still rely on IP fragmentation, and to be fair linux
reassembly unit is not working under any serious load.
It uses static hash tables of 1024 buckets, and up to 128 items per bucket (!!!)
A work queue is supposed to garbage collect items when host is under memory
pressure, and doing a hash rebuild, changing seed used in hash computations.
This work queue blocks softirqs for up to 25 ms when doing a hash rebuild,
occurring every 5 seconds if host is under fire.
Then there is the problem of sharing this hash table for all netns.
It is time to switch to rhashtables, and allocate one of them per netns
to speedup netns dismantle, since this is a critical metric these days.
Lookup is now using RCU. A followup patch will even remove
the refcount hold/release left from prior implementation and save
a couple of atomic operations.
Before this patch, 16 cpus (16 RX queue NIC) could not handle more
than 1 Mpps frags DDOS.
After the patch, I reach 9 Mpps without any tuning, and can use up to 2GB
of storage for the fragments (exact number depends on frags being evicted
after timeout)
$ grep FRAG /proc/net/sockstat
FRAG: inuse 1966916 memory 2140004608
A followup patch will change the limits for 64bit arches.

When we umount f2fs, we need to avoid long delay due to discard commands, which
is actually taking tens of seconds, if storage is very slow on UNMAP. So, this
patch introduces timeout-based work on it.
By default, let me give 5 seconds for discard.
