>From PD Spec:
The Sink Shall transition to Sink Standby before a positive or
negative voltage transition of VBUS. During Sink Standby
the Sink Shall reduce its power draw to pSnkStdby. This allows
the Source to manage the voltage transition as well as
supply sufficient operating current to the Sink to maintain PD
operation during the transition. The Sink Shall
complete this transition to Sink Standby within tSnkStdby
after evaluating the Accept Message from the Source. The
transition when returning to Sink operation from Sink Standby
Shall be completed within tSnkNewPower. The
pSnkStdby requirement Shall only apply if the Sink power draw
is higher than this level.
The above requirement needs to be met to prevent hard resets
from port partner.
Without the patch: (5V/3A during SNK_DISCOVERY all the way through
explicit contract)

Current trusted keys framework is tightly coupled to use TPM device as
an underlying implementation which makes it difficult for implementations
like Trusted Execution Environment (TEE) etc. to provide trusted keys
support in case platform doesn't posses a TPM device.
Add a generic trusted keys framework where underlying implementations
can be easily plugged in. Create struct trusted_key_ops to achieve this,
which contains necessary functions of a backend.
Also, define a module parameter in order to select a particular trust
source in case a platform support multiple trust sources. In case its
not specified then implementation itetrates through trust sources list
starting with TPM and assign the first trust source as a backend which
has initiazed successfully during iteration.
Note that current implementation only supports a single trust source at
runtime which is either selectable at compile time or during boot via
aforementioned module parameter.

The current implementation appends a migratable flag to the end of a
key, meaning the format isn't exactly interoperable because the using
party needs to know to strip this extra byte. However, all other
consumers of TPM sealed blobs expect the unseal to return exactly the
key. Since TPM2 keys have a key property flag that corresponds to
migratable, use that flag instead and make the actual key the only
sealed quantity. This is secure because the key properties are bound
to a hash in the private part, so if they're altered the key won't
load.
Backwards compatibility is implemented by detecting whether we're
loading a new format key or not and correctly setting migratable from
the last byte of old format keys.

Modify the TPM2 key format blob output to export and import in the
ASN.1 form for TPM2 sealed object keys. For compatibility with prior
trusted keys, the importer will also accept two TPM2B quantities
representing the public and private parts of the key. However, the
export via keyctl pipe will only output the ASN.1 format.
The benefit of the ASN.1 format is that it's a standard and thus the
exported key can be used by userspace tools (openssl_tpm2_engine,
openconnect and tpm2-tss-engine). The format includes policy
specifications, thus it gets us out of having to construct policy
handles in userspace and the format includes the parent meaning you
don't have to keep passing it in each time.
This patch only implements basic handling for the ASN.1 format, so
keys with passwords but no policy.

In TPM 1.2 an authorization was a 20 byte number. The spec actually
recommended you to hash variable length passwords and use the sha1
hash as the authorization. Because the spec doesn't require this
hashing, the current authorization for trusted keys is a 40 digit hex
number. For TPM 2.0 the spec allows the passing in of variable length
passwords and passphrases directly, so we should allow that in trusted
keys for ease of use. Update the 'blobauth' parameter to take this
into account, so we can now use plain text passwords for the keys.
so before
keyctl add trusted kmk "new 32 blobauth=f572d396fae9206628714fb2ce00f72e94f2258fkeyhandle=81000001" @u
after we will accept both the old hex sha1 form as well as a new
directly supplied password:
keyctl add trusted kmk "new 32 blobauth=hello keyhandle=81000001" @u
Since a sha1 hex code must be exactly 40 bytes long and a direct
password must be 20 or less, we use the length as the discriminator
for which form is input.
Note this is both and enhancement and a potential bug fix. The TPM
2.0 spec requires us to strip leading zeros, meaning empyty
authorization is a zero length HMAC whereas we're currently passing in
20 bytes of zeros. A lot of TPMs simply accept this as OK, but the
Microsoft TPM emulator rejects it with TPM_RC_BAD_AUTH, so this patch
makes the Microsoft TPM emulator work with trusted keys.

The TCG has defined an OID prefix "2.23.133.10.1" for the various TPM
key uses. We've defined three of the available numbers:
2.23.133.10.1.3 TPM Loadable key. This is an asymmetric key (Usually
RSA2048 or Elliptic Curve) which can be imported by a
TPM2_Load() operation.
2.23.133.10.1.4 TPM Importable Key. This is an asymmetric key (Usually
RSA2048 or Elliptic Curve) which can be imported by a
TPM2_Import() operation.
Both loadable and importable keys are specific to a given TPM, the
difference is that a loadable key is wrapped with the symmetric
secret, so must have been created by the TPM itself. An importable
key is wrapped with a DH shared secret, and may be created without
access to the TPM provided you know the public part of the parent key.
2.23.133.10.1.5 TPM Sealed Data. This is a set of data (up to 128
bytes) which is sealed by the TPM. It usually
represents a symmetric key and must be unsealed before
use.
The ASN.1 binary key form starts of with this OID as the first element
of a sequence, giving the binary form a unique recognizable identity
marker regardless of encoding.

We have a need in the TPM2 trusted keys to return the ASN.1 form of the TPM
key blob so it can be operated on by tools outside of the kernel. The
specific tools are the openssl_tpm2_engine, openconnect and the Intel
tpm2-tss-engine. To do that, we have to be able to read and write the same
binary key format the tools use. The current ASN.1 decoder does fine for
reading, but we need pieces of an ASN.1 encoder to write the key blob in
binary compatible form.
For backwards compatibility, the trusted key reader code will still accept
the two TPM2B quantities that it uses today, but the writer will only
output the ASN.1 form.
The current implementation only encodes the ASN.1 bits we actually need.

This change introduces a prctl that allows the user program to control
which PAC keys are enabled in a particular task. The main reason
why this is useful is to enable a userspace ABI that uses PAC to
sign and authenticate function pointers and other pointers exposed
outside of the function, while still allowing binaries conforming
to the ABI to interoperate with legacy binaries that do not sign or
authenticate pointers.
The idea is that a dynamic loader or early startup code would issue
this prctl very early after establishing that a process may load legacy
binaries, but before executing any PAC instructions.
This change adds a small amount of overhead to kernel entry and exit
due to additional required instruction sequences.
On a DragonBoard 845c (Cortex-A75) with the powersave governor, the
overhead of similar instruction sequences was measured as 4.9ns when
simulating the common case where IA is left enabled, or 43.7ns when
simulating the uncommon case where IA is disabled. These numbers can
be seen as the worst case scenario, since in more realistic scenarios
a better performing governor would be used and a newer chip would be
used that would support PAC unlike Cortex-A75 and would be expected
to be faster than Cortex-A75.
On an Apple M1 under a hypervisor, the overhead of the entry/exit
instruction sequences introduced by this patch was measured as 0.3ns
in the case where IA is left enabled, and 33.0ns in the case where
IA is disabled.

Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature
sensor reading"), Linux reports the temperature of Topaz hwmon as
constant -75°C.
This is because switches from the Topaz family (88E6141 / 88E6341) have
the address of the temperature sensor register different from Peridot.
This address is instead compatible with 88E1510 PHYs, as was used for
Topaz before the above mentioned commit.
Create a new mapping table between switch family and PHY ID for families
which don't have a model number. And define PHY IDs for Topaz and Peridot
families.
Create a new PHY ID and a new PHY driver for Topaz's internal PHY.
The only difference from Peridot's PHY driver is the HWMON probing
method.
Prior this change Topaz's internal PHY is detected by kernel as:
PHY [...] driver [Marvell 88E6390] (irq=63)
And afterwards as:
PHY [...] driver [Marvell 88E6341 Family] (irq=63)

There's a substantial amount of boilerplate in filesystems handling
FS_IOC_[GS]ETFLAGS/ FS_IOC_FS[GS]ETXATTR ioctls.
Also due to userspace buffers being involved in the ioctl API this is
difficult to stack, as shown by overlayfs issues related to these ioctls.
Introduce a new internal API named "fileattr" (fsxattr can be confused with
xattr, xflags is inappropriate, since this is more than just flags).
There's significant overlap between flags and xflags and this API handles
the conversions automatically, so filesystems may choose which one to use.
In ->fileattr_get() a hint is provided to the filesystem whether flags or
xattr are being requested by userspace, but in this series this hint is
ignored by all filesystems, since generating all the attributes is cheap.
If a filesystem doesn't implemement the fileattr API, just fall back to
f_op->ioctl(). When all filesystems are converted, the fallback can be
removed.
32bit compat ioctls are now handled by the generic code as well.

Sometimes we need to get the corresponding gendisk from request_queue.
It is preferred that block drivers store private data in
gendisk->private_data rather than request_queue->queuedata, e.g. see:
commit c4a59c4e5db3 ("dm: stop using ->queuedata").
So if only request_queue is given, we need to get its corresponding
gendisk to get the private data stored in that gendisk.

The only exported helper we have right now is task_work_cancel(), which
cancels any task_work from a given task where func matches the queued
work item. This is a bit too coarse for some use cases. Add a
task_work_cancel_match() that allows to more specifically target
individual work items outside of purely the callback function used.
task_work_cancel() can be trivially implemented on top of that, hence do
so.

This adds two new POLL_ADD flags, IORING_POLL_UPDATE_EVENTS and
IORING_POLL_UPDATE_USER_DATA. As with the other POLL_ADD flag, these are
masked into sqe->len. If set, the POLL_ADD will have the following
behavior:
- sqe->addr must contain the the user_data of the poll request that
needs to be modified. This field is otherwise invalid for a POLL_ADD
command.
- If IORING_POLL_UPDATE_EVENTS is set, sqe->poll_events must contain the
new mask for the existing poll request. There are no checks for whether
these are identical or not, if a matching poll request is found, then it
is re-armed with the new mask.
- If IORING_POLL_UPDATE_USER_DATA is set, sqe->off must contain the new
user_data for the existing poll request.
A POLL_ADD with any of these flags set may complete with any of the
following results:
1) 0, which means that we successfully found the existing poll request
specified, and performed the re-arm procedure. Any error from that
re-arm will be exposed as a completion event for that original poll
request, not for the update request.
2) -ENOENT, if no existing poll request was found with the given
user_data.
3) -EALREADY, if the existing poll request was already in the process of
being removed/canceled/completing.
4) -EACCES, if an attempt was made to modify an internal poll request
(eg not one originally issued ass IORING_OP_POLL_ADD).
The usual -EINVAL cases apply as well, if any invalid fields are set
in the sqe for this command type.

The default io_uring poll mode is one-shot, where once the event triggers,
the poll command is completed and won't trigger any further events. If
we're doing repeated polling on the same file or socket, then it can be
more efficient to do multishot, where we keep triggering whenever the
event becomes true.
This deviates from the usual norm of having one CQE per SQE submitted. Add
a CQE flag, IORING_CQE_F_MORE, which tells the application to expect
further completion events from the submitted SQE. Right now the only user
of this is POLL_ADD in multishot mode.
Since sqe->poll_events is using the space that we normally use for adding
flags to commands, use sqe->len for the flag space for POLL_ADD. Multishot
mode is selected by setting IORING_POLL_ADD_MULTI in sqe->len. An
application should expect more CQEs for the specificed SQE if the CQE is
flagged with IORING_CQE_F_MORE. In multishot mode, only cancelation or an
error will terminate the poll request, in which case the flag will be
cleared.

MHI changes for v5.13
core:
- Added support for Flash Programmer execution environment which allows the
host machine (like x86) to flash the modem firmware to NAND or eMMC in the
modem. The MHI bus will expose EDL channels (34, 35) and then the opensource
QDL tool [1] can be used to flash the firmware from the host.
- Added an internal helper for polling the MHI registers with a retry interval.
This helper is used now to poll for the MHI ready state in MHI STATUS
register.
- Various fixes for issues found during the bringup of SDX24/SDX55 based Quectel
and Telit modems.
- Updates to the Execution environment handling for proper downloading of the
AMSS image from SBL (Secondary Bootloader) mode.
- Added support for sending STOP channel command to the MHI device and also made
changes to the MHI core for proper handling of stop and restart.
- Fixed the runtime_pm handling in the core by forcing the device to be in wake
mode until TX completion and allowing it to suspend for RX.
- Added sanity checks for values read from the device to avoid crash if those
are corrupted somehow.
- Fixed warnings generated by sparse (W=2)
- Couple of kernel doc cleanups in mhi.h

- Added support for runtime PM and generic PM
- Added Firehose channels for flashing the firmware
- Added support for modems such as Quectel EM1XXGR-L, SDX24, SDX65, Foxconn

Because we support a single user, we can reset the device (if needs to)
after a user closes its file descriptor to make sure the device is in
idle and clean state for the next user.
- Add a new feature to allow the user to wait on interrupt. This is needed
for future ASICs
- Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to
support failure of allocating with GFP_ATOMIC.

- More security features are done in the firmware
- Remove hard-coded assumptions and replace them with values that are
sent to the firmware on loading.
- Print device unusable error
- Reset device in case the communication between driver and firmware
gets out of sync.

Same problem that also existed in iptables/ip(6)tables, when
arptable_filter is removed there is no longer a wait period before the
table/ruleset is free'd.
Unregister the hook in pre_exit, then remove the table in the exit
function.
This used to work correctly because the old nf_hook_unregister API
did unconditional synchronize_net.
The per-net hook unregister function uses call_rcu instead.

Just like ip/ip6/arptables, the hooks have to be removed, then
synchronize_rcu() has to be called to make sure no more packets are being
processed before the ruleset data is released.
Place the hook unregistration in the pre_exit hook, then call the new
ebtables pre_exit function from there.
Years ago, when first netns support got added for netfilter+ebtables,
this used an older (now removed) netfilter hook unregister API, that did
a unconditional synchronize_rcu().
Now that all is done with call_rcu, ebtable_{filter,nat,broute} pernet exit
handlers may free the ebtable ruleset while packets are still in flight.
This can only happens on module removal, not during netns exit.
The new function expects the table name, not the table struct.
This is because upcoming patch set (targeting -next) will remove all
net->xt.{nat,filter,broute}_table instances, this makes it necessary
to avoid external references to those member variables.
The existing APIs will be converted, so follow the upcoming scheme of
passing name + hook type instead.

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.

Commit 30004ac9c090 ("tty: add tty_struct->dev pointer to corresponding

tty_struct which was populated with the corresponding tty class device
during initialisation.
Unfortunately, not all ttys have a class device (e.g. pseudoterminals
and serdev) in which case the device pointer will be set to NULL,
something which have bit driver authors over the years.
In retrospect perhaps this field should never have been added, but let's
at least document the current behaviour.

[Why]
Previous tdr design treats the first job in job_timeout as the bad job.
But sometimes a later bad compute job can block a good gfx job and
cause an unexpected gfx job timeout because gfx and compute ring share
internal GC HW mutually.
[How]
This patch implements an advanced tdr mode.It involves an additinal
synchronous pre-resubmit step(Step0 Resubmit) before normal resubmit
step in order to find the real bad job.
1. At Step0 Resubmit stage, it synchronously submits and pends for the
first job being signaled. If it gets timeout, we identify it as guilty
and do hw reset. After that, we would do the normal resubmit step to
resubmit left jobs.
2. For whole gpu reset(vram lost), do resubmit as the old way.
