The hardware requirement for delay between assert/deassert
is at least 3-4 sleep clock (32.7KHz) cycles, which comes to
~125us (4/32768). To be on the safe side add 200us delay.

When a filesystem driver calls into makes a RPM request, RPM driver
makes a kzalloc request with GFP_NOFS flag. This results in a
deadlock if a driver waiting on IO completion sends a RPM message.

Decrease the wait time from 5ms to 2ms when preparing a VDM
response to ensure that it gets sent out timely within
tSenderResponse (15ms). To avoid possible collision with an
incoming packet, check that there has not been any queued Rx
message just prior to sending a VDM. Also check the result of the
transmit and simply try again later if -EBUSY is returned.
While at it, fix a couple other miscellaneous timing issues.
Setting PD_ACTIVE=1 has considerable delay due to the charger's
voting mechanism, so move setting it to after starting the
SenderResponse timer when sending the Source Capabilities, and
similarly after sending a Request as a sink, in order to make
sure response timing is met. For source hard reset, increase the
tSrcRecover delay slightly from the spec minimum to account for
additional VBUS rise/fall delays before sending PS_RDY. Finally,
add a delay for VCONN_SWAP before sending PS_RDY for similar reason.

To avoid missing an incoming packet that was quickly sent while
still processing the previous packet, clear the acknowledge bit
as soon as the message is consumed from the Rx FIFO. This gives
the hardware a chance to send a GoodCRC without causing the
sender to retry.

If an unexpected or delayed Type-C mode change notification
arrives from the charger driver, it could falsely kick the
state machine and could cause it to prematurely hard reset
since it preempted an expected message. This is particularly
true for the PR Swap operation in which the timing of PS_RDY
and resulting power negotiation is disrupted by the CC change
notification which is catching up. The previous way of handling
this by using the pd->in_pr_swap flag to mask the typec_mode
changes is quite fragile due to the uncertainty of when said
flag should be cleared.
Hence, demote the use of the in_pr_swap flag for only ignoring
the expected disconnect the happens in between the role change.
Then, for typec_mode changes, determine if current_pr is changed
or not to decide whether to kick the state machine. Finally,
since disconnect now is signaled by pd->current_pr==PR_NONE,
we'll need to keep track of whether VBUS had been enabled with
a separate flag rather than relying on pd->current_pr==PR_SRC.

Make sure to reset both Tx and Rx msgid counters when the

The current hard reset handling (most recently fixed with
commit 172cec3a2c ("usb: pd: Improve sink hard reset handling"))
is based on a maximum timeout for the longest possible (according
to spec) duration that VBUS may turn off and back on again, just
under 2s, before re-starting the sink and waiting for capabilities
again. However, this method is prone to timing errors, particularly
tTypeCSinkWaitCap, which should be based on when VBUS turns on.
Fix this by making use of the VBUS presence notification from the
charger (PROP_PRESENT). Keep track of this in the psy_changed()
callback and use the falling notification to determine when to
transition out of PE_SNK_TRANSITION_TO_DEFAULT into PE_SNK_STARTUP.
Bring back PE_SNK_DISCOVERY which is now used as a waiting state
until the VBUS rising notification comes and transition to
PE_SNK_WAIT_FOR_CAPABILITIES. And move setting of PROP_VOLTAGE_MAX
to PE_SNK_STARTUP after VBUS has turned off to avoid tripping
the charger's overvoltage detection.
Also since aforementioned commit, the CC HW is now able to handle
VBUS going away and not treating it as a false disconnect, so we
can remove the workaround as a disconnect can now be treated as
a disconnect.

There is a double fetch problem in audit_log_single_execve_arg()
where we first check the execve(2) argumnets for any "bad" characters
which would require hex encoding and then re-fetch the arguments for
logging in the audit record[1]. Of course this leaves a window of
opportunity for an unsavory application to munge with the data.
This patch reworks things by only fetching the argument data once[2]
into a buffer where it is scanned and logged into the audit
records(s). In addition to fixing the double fetch, this patch
improves on the original code in a few other ways: better handling
of large arguments which require encoding, stricter record length
checking, and some performance improvements (completely unverified,
but we got rid of some strlen() calls, that's got to be a good
thing).
As part of the development of this patch, I've also created a basic
regression test for the audit-testsuite, the test can be tracked on
GitHub at the following link:
* https://github.com/linux-audit/audit-testsuite/issues/25
[1] If you pay careful attention, there is actually a triple fetch
problem due to a strnlen_user() call at the top of the function.
[2] This is a tiny white lie, we do make a call to strnlen_user()
prior to fetching the argument data. I don't like it, but due to the
way the audit record is structured we really have no choice unless we
copy the entire argument at once (which would require a rather
wasteful allocation). The good news is that with this patch the
kernel no longer relies on this strnlen_user() value for anything
beyond recording it in the log, we also update it with a trustworthy
value whenever possible.

Export an instance of the dual_role_usb class using the
provided helpers. This is an alternate set of sysfs nodes
that the Android framework uses to allow for user
interactive control of role switching.
Writing to the various properties achieves the following:
- mode: toggles between UFP/Sink and DFP/Source via soft
disconnect/reconnect without invoking PD.
- power_role: toggles between Source and Sink modes via
the PR_Swap operation
- data_role: toggles between UFP (device) and DFP (host) via
the DR_Swap operation
Android currently expects a single instance named "otg_default".
