usb: fixes for v4.15-rc4
We have a few fixes on dwc3:
- one fix which only happens with some implementations where we need to
wait longer for some commands to finish.
- Another fix for high-bandwidth isochronous endpoint programming making
sure that we send the correct DATA tokens in the correct sequence
- A couple PM fixes on dwc3-of-simple
The other synopsys controller driver (dwc2) got a fix for FIFO size
programming.
Other than these, we have a couple Kconfig fixes making sure that
dependencies are properly setup.

The ARM architecture defines the memory locations that are permitted
to be accessed as the result of a speculative instruction fetch from
an exception level for which all stages of translation are disabled.
Specifically, the core is permitted to speculatively fetch from the
4KB region containing the current program counter 4K and next 4K.
When translation is changed from enabled to disabled for the running
exception level (SCTLR_ELn[M] changed from a value of 1 to 0), the
Falkor core may errantly speculatively access memory locations outside
of the 4KB region permitted by the architecture. The errant memory
access may lead to one of the following unexpected behaviors.
1) A System Error Interrupt (SEI) being raised by the Falkor core due
to the errant memory access attempting to access a region of memory
that is protected by a slave-side memory protection unit.
2) Unpredictable device behavior due to a speculative read from device
memory. This behavior may only occur if the instruction cache is
disabled prior to or coincident with translation being changed from
enabled to disabled.
The conditions leading to this erratum will not occur when either of the
following occur:
1) A higher exception level disables translation of a lower exception level
(e.g. EL2 changing SCTLR_EL1[M] from a value of 1 to 0).
2) An exception level disabling its stage-1 translation if its stage-2
translation is enabled (e.g. EL1 changing SCTLR_EL1[M] from a value of 1
to 0 when HCR_EL2[VM] has a value of 1).
To avoid the errant behavior, software must execute an ISB immediately
prior to executing the MSR that will change SCTLR_ELn[M] from 1 to 0.

Jiankang reports that our race detection in set_pte_at is firing when
copying the page tables in dup_mmap as a result of a fork(). In this
situation, the page table isn't actually live and so there is no way
that we can race with a concurrent update from the hardware page table
walker.
This patch reworks the race detection so that we require either the
mm to match the current active_mm (i.e. currently installed in our TTBR0)
or the mm_users count to be greater than 1, implying that the page table
could be live in another CPU. The mm_users check might still be racy,
but we'll avoid false positives and it's not realistic to validate that
all the necessary locks are held as part of this assertion.

This code (CONFIG_LOCKDEP_CROSSRELEASE=y and CONFIG_LOCKDEP_COMPLETIONS=y),
while it found a number of old bugs initially, was also causing too many
false positives that caused people to disable lockdep - which is arguably
a worse overall outcome.
If we disable cross-release by default but keep the code upstream then
in practice the most likely outcome is that we'll allow the situation
to degrade gradually, by allowing entropy to introduce more and more
false positives, until it overwhelms maintenance capacity.
Another bad side effect was that people were trying to work around
the false positives by uglifying/complicating unrelated code. There's
a marked difference between annotating locking operations and
uglifying good code just due to bad lock debugging code ...
This gradual decrease in quality happened to a number of debugging
facilities in the kernel, and lockdep is pretty complex already,
so we cannot risk this outcome.
Either cross-release checking can be done right with no false positives,
or it should not be included in the upstream kernel.
( Note that it might make sense to maintain it out of tree and go through
the false positives every now and then and see whether new bugs were
introduced. )

This reverts commit 7a9618a22aadffb55027d665491adf466bced61a.
Romain Izard recently reported that commit 7a9618a22aad ended up
allowing every legacy gadget driver to statically linked to the
kernel, however that doesn't work, since only one legacy gadget can be
bound to a controller. Because of that, let's revert the original commit
and fix the problem.

Configuring the USB_G_WEBCAM driver as built-in leads to a link
error when CONFIG_VIDEO_V4L2 is a loadable module:

drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_ep0_complete':
f_uvc.c:(.text+0x188): undefined reference to `v4l2_event_queue'
This changes the Kconfig dependency to disallow that configuration,
and force it to be a module in that case as well.
This is apparently a rather old bug, but very hard to trigger
even in thousands of randconfig builds.

When CONFIG_GENERIC_LOCKBEAK=y, locking structures grow an extra int ->break_lock
field which is used to implement raw_spin_is_contended() by setting the field
to 1 when waiting on a lock and clearing it to zero when holding a lock.
However, there are a few problems with this approach:
- There is a write-write race between a CPU successfully taking the lock
(and subsequently writing break_lock = 0) and a waiter waiting on
the lock (and subsequently writing break_lock = 1). This could result
in a contended lock being reported as uncontended and vice-versa.
- On machines with store buffers, nothing guarantees that the writes
to break_lock are visible to other CPUs at any particular time.
- READ_ONCE/WRITE_ONCE are not used, so the field is potentially
susceptible to harmful compiler optimisations,
Consequently, the usefulness of this field is unclear and we'd be better off
removing it and allowing architectures to implement raw_spin_is_contended() by
providing a definition of arch_spin_is_contended(), as they can when
CONFIG_GENERIC_LOCKBREAK=n.

Commit:
a8a217c22116 ("locking/core: Remove {read,spin,write}_can_lock()")
removed the definition of raw_spin_can_lock(), causing the GENERIC_LOCKBREAK
spin_lock() routines to poll the ->break_lock field when waiting on a lock.
This has been reported to cause a deadlock during boot on s390, because
the ->break_lock field is also set by the waiters, and can potentially
remain set indefinitely if no other CPUs come in to take the lock after
it has been released.
This patch removes the explicit spinning on ->break_lock from the waiters,
instead relying on the outer trylock() operation to determine when the
lock is available.

Avoid that scsi_show_rq() triggers a NULL pointer dereference if called
after sd_uninit_command(). Swap the NULL pointer assignment and the
mempool_free() call in sd_uninit_command() to make it less likely that
scsi_show_rq() triggers a use-after-free. Note: even with these changes
scsi_show_rq() can trigger a use-after-free but that's a lesser evil
than e.g. suppressing debug information for T10 PI Type 2 commands
completely. This patch fixes the following oops:

The return value of smp_execute_task_sg() is the untransferred residual,
but bsg_job_done() requires the length of payload received. This makes
SMP passthrough commands from userland by sg ioctl to libsas get a wrong
response. The userland tools such as smp_utils failed because of these
wrong responses:
~#smp_discover /dev/bsg/expander-2\:13
response too short, len=0
~#smp_discover /dev/bsg/expander-2\:134
response too short, len=0
Fix this by passing the actual received length to bsg_job_done(). And if
smp_execute_task_sg() returns 0, this means received length is exactly
the buffer length.

Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake
order of events that does not exist on the device.
Recent versions of libinput changed to only process the device state and
SYN_REPORT time, so now the key event is lost.

Only insert our special drain CQEs to support ib_drain_sq/rq() after
the wq is flushed. Otherwise, existing but not yet polled CQEs can be
returned out of order to the user application. This can happen when the
QP has exited RTS but not yet flushed the QP, which can happen during
a normal close (vs abortive close).
In addition never count the drain CQEs when determining how many CQEs
need to be synthesized during the flush operation. This latter issue
should never happen if the QP is properly flushed before inserting the
drain CQE, but I wanted to avoid corrupting the CQ state. So we handle
it and log a warning once.

This happens because the directory that ext4_find_entry() looks up has
inode->i_size that is less than the block size of the filesystem. This
causes 'nblocks' to have a value of zero. ext4_bread_batch() ends up not
reading any of the directory file's blocks. This renders the entries in
bh_use[] array to continue to have garbage data. buffer_uptodate() on
bh_use[0] can then return a zero value upon which brelse() function is
invoked.
This commit fixes the bug by returning -ENOENT when the directory file
has no associated blocks.

common torpedo already in its own file, we can very easily
create a new devkit specific for the OMAP35xx.

The Development kits consist of a SOM connected to a baseboard. Moving most
of the devkit files to baseboard allow us to re-use much of the contents in
preparation for using it on the OMAP35xx varation of the same kit.

Currently, a nlmon link inside a child namespace can observe systemwide
netlink activity. Filter the traffic so that nlmon can only sniff
netlink messages from its own netns.
Test case:
vpnns -- bash -c "ip link add nlmon0 type nlmon; \
ip link set nlmon0 up; \
tcpdump -i nlmon0 -q -w /tmp/nlmon.pcap -U" &
sudo ip xfrm state add src 10.1.1.1 dst 10.1.1.2 proto esp \
spi 0x1 mode transport \
auth sha1 0x6162633132330000000000000000000000000000 \
enc aes 0x00000000000000000000000000000000
grep --binary abc123 /tmp/nlmon.pcap

Not all variants of the sh_eth hardware have Gigabit
support. Unfortunately, the current driver doesn't tell the PHY about
the limited MAC capabilities. Due to this, if you have a Gigabit
capable PHY, the PHY will advertise its Gigabit capability and
establish a link at 1Gbit/s, even though the MAC doesn't support it.
In order to avoid this, we use the recently introduced
phy_set_max_speed() to tell the PHY to not advertise speed higher than
100 MBit/s.
Tested on a SH7786 platform, with a Gigabit PHY.

The metastability workaround causes Erratic errors [1]
on the HighSpeed USB PHY which can cause upto 2 seconds
delay in enumerating to a USB host while in Gadget mode.
Disable the Run/Stop metastability workaround to avoid this
ill effect. We are aware that this opens up the opportunity
for Run/Stop metastability, however this issue has never been
observed in TI releases so we think that Run/Stop metastability
is a lesser evil than the PHY Erratic errors. So disable it.
