To avoid any OOB write or other security issues, it's good to
validate the buffer size before accessing it.

Currently,stop transfer is done based on missed isoc packets
which can cause issue when software list is empty with no missed
isoc.
Issue stop active transfers if started list is empty.
Also,Frame_number is set from XferNotReady and may be already
out of date. DSTS only provides the lower 14 bit of the
current frame number. So add the upper two bits of
frame_number and handle a possible rollover.
This will provide the correct frame_number unless more than
rollover has happened since XferNotReady.
Increase TX fifo size for isochronous endpoint in case maxburst
is greater than 6 for better performance.
Added Endtransfer logic to be called when BUS expiry happens due
to frame mismatch.

Do not overwrite download mode to NO dump mode from SCM driver, it is
already being done at proper place in qcom-dload-mode driver and
writing it here can clean up EDL mode written from qcom-dload-mode.
Fix this issue by remove writing no dump mode from SCM driver.

Currently i2c geni driver doesn't have null pointer check condition

i2c geni driver accessing null pointer which is causing crash.
To solve this added null pointer checks in event call back functions.

Introduce restart handler to handle "echo b > /proc/sysrq-trigger".
One special thing with 'b' kind of reboot is, it does not call reboot
notifiers and call restart handler right a way and that does not seems
to work for blair SoC and it goes to dump mode.
Keep this restart handler priority to 201 greater than 200 which is the
priority for msm-poweroff to make reboot work cleaner.

Intel host tends to retrain the link if device doesn't send PM_Enter_L23
in time, leading to linkdown and hot reset in device side. The hot reset
here even results to PERST# timeout and device crash to PBL, which is
not expected.
Since we are in the entry of shutdown the link when linkdown happen, it
makes sense to ignore the linkdown. To avoid device crash because of
PERST# timeout, disable hot reset in pm_turnoff irq and reenable it when
we do linktrain again.

The patches to support binder's frozen notification feature break the
KMI. This change fixes such issues by (1) moving proc->delivered_freeze
into the existing proc_wrapper struction, (2) dropping the frozen stats
support and (3) amending the STG due to a harmless enum binder_work_type
addition.
These are the reported KMI issues fixed by this patch:

Frozen processes present a significant challenge in binder transactions.
When a process is frozen, it cannot, by design, accept and/or respond to
binder transactions. As a result, the sender needs to adjust its
behavior, such as postponing transactions until the peer process
unfreezes. However, there is currently no way to subscribe to these
state change events, making it impossible to implement frozen-aware
behaviors efficiently.
Introduce a binder API for subscribing to frozen state change events.
This allows programs to react to changes in peer process state,
mitigating issues related to binder transactions sent to frozen
processes.
Implementation details:
For a given binder_ref, the state of frozen notification can be one of
the followings:
1. Userspace doesn't want a notification. binder_ref->freeze is null.
2. Userspace wants a notification but none is in flight.
list_empty(&binder_ref->freeze->work.entry) = true
3. A notification is in flight and waiting to be read by userspace.
binder_ref_freeze.sent is false.
4. A notification was read by userspace and kernel is waiting for an ack.
binder_ref_freeze.sent is true.
When a notification is in flight, new state change events are coalesced into
the existing binder_ref_freeze struct. If userspace hasn't picked up the
notification yet, the driver simply rewrites the state. Otherwise, the
notification is flagged as requiring a resend, which will be performed
once userspace acks the original notification that's inflight.
See https://r.android.com/3070045 for how userspace is going to use this
feature.

Provide userspace with a mechanism to discover features supported by
the binder driver to refrain from using any unsupported ones in the
first place. Starting with "oneway_spam_detection" only new features
are to be listed under binderfs and all previous ones are assumed to
be supported.
Assuming an instance of binderfs has been mounted at /dev/binderfs,
binder feature files can be found under /dev/binderfs/features/.
Usage example:
$ mkdir /dev/binderfs
$ mount -t binder binder /dev/binderfs
$ cat /dev/binderfs/features/oneway_spam_detection

commit 1aa3aaf8953c84bad398adf6c3cabc9d6685bf7d upstream
A transaction complete work is allocated and queued for each
transaction. Under certain conditions the work->type might be marked as
BINDER_WORK_TRANSACTION_ONEWAY_SPAM_SUSPECT to notify userspace about
potential spamming threads or as BINDER_WORK_TRANSACTION_PENDING when
the target is currently frozen.
However, these work types are not being handled in binder_release_work()
so they will leak during a cleanup. This was reported by syzkaller with
the following kmemleak dump:

When the target process is busy, incoming oneway transactions are
queued in the async_todo list. If the clients continue sending extra
oneway transactions while the target process is frozen, this queue can
become too large to accommodate new transactions. That's why binder
driver introduced ONEWAY_SPAM_DETECTION to detect this situation. It's
helpful to debug the async binder buffer exhausting issue, but the
issue itself isn't solved directly.
In real cases applications are designed to send oneway transactions
repeatedly, delivering updated inforamtion to the target process.
Typical examples are Wi-Fi signal strength and some real time sensor
data. Even if the apps might only care about the lastet information,
all outdated oneway transactions are still accumulated there until the
frozen process is thawed later. For this kind of situations, there's
no existing method to skip those outdated transactions and deliver the
latest one only.
This patch introduces a new transaction flag TF_UPDATE_TXN. To use it,
use apps can set this new flag along with TF_ONE_WAY. When such an
oneway transaction is to be queued into the async_todo list of a frozen
process, binder driver will check if any previous pending transactions
can be superseded by comparing their code, flags and target node. If
such an outdated pending transaction is found, the latest transaction
will supersede that outdated one. This effectively prevents the async
binder buffer running out and saves unnecessary binder read workloads.

When async binder buffer got exhausted, some normal oneway transactions
will also be discarded and may cause system or application failures. By
that time, the binder debug information we dump may not be relevant to
the root cause. And this issue is difficult to debug if without the
backtrace of the thread sending spam.
This change will send BR_ONEWAY_SPAM_SUSPECT to userspace when oneway
spamming is detected, request to dump current backtrace. Oneway spamming
will be reported only once when exceeding the threshold (target process
dips below 80% of its oneway space, and current process is responsible
for either more than 50 transactions, or more than 50% of the oneway
space). And the detection will restart when the async buffer has
returned to a healthy state.

increases the usage refcount. If the IOCTL using the
get_current_groups API is called many times, the usage counter
overflows. To avoid this, access group info without taking a
reference. A reference is not required as group info is not
released during the IOCTL call.

Currently, the DSP updates header buffers with unused DMA handle fds.
In the put_args section, if any DMA handle FDs are present in the
header buffer, the corresponding map is freed. However, since the
header buffer is exposed to users in unsigned PD, users can update
invalid FDs. If this invalid FD matches with any FD that is already
in use, it could lead to a use-after-free (UAF) vulnerability.
As a solution,add DMA handle references for DMA FDs, and the map for
the FD will be freed only when a reference is found.
