Set underlay QPN as part of flow rule when it's applicable.
There is one root flow table in the NIC RX namespace and all the
underlay QPs steer the traffic to this flow table.
In order to prevent QP to get traffic which is not target to its
underlay QP, we need to set the underlay QP number as part of
the steering matching.
Note:
When multicast traffic is sent the QPN filtering is done by the firmware
as some early step. Adding the QPN match on the flow table entry is
wrong as by that time the target QPN holds the multicast address (e.g.
FF(s)) and it won't match.

This patch is the first step in decoupling UMR usage and
allocation from the MR cache. The only functional change
in this patch is to enables UMR for MRs created with
reg_create.
This change fixes a bug where ODP memory regions that
were not allocated from the MR cache did not have UMR
enabled.

The implementation of TIOCGPTPEER has two issues.
When /dev/ptmx (as opposed to /dev/pts/ptmx) is opened the wrong
vfsmount is passed to dentry_open. Which results in the kernel displaying
the wrong pathname for the peer.
The second is simply by caching the vfsmount and dentry of the peer it leaves
them open, in a way they were not previously Which because of the inreased
reference counts can cause unnecessary behaviour differences resulting in
regressions.
To fix these move the ioctl into tty_io.c at a generic level allowing
the ioctl to have access to the struct file on which the ioctl is
being called. This allows the path of the slave to be derived when
opening the slave through TIOCGPTPEER instead of requiring the path to
the slave be cached. Thus removing the need for caching the path.
A new function devpts_ptmx_path is factored out of devpts_acquire and
used to implement a function devpts_mntget. The new function devpts_mntget
takes a filp to perform the lookup on and fsi so that it can confirm
that the superblock that is found by devpts_ptmx_path is the proper superblock.
v2: Lots of fixes to make the code actually work
v3: Suggestions by Linus
- Removed the unnecessary initialization of filp in ptm_open_peer
- Simplified devpts_ptmx_path as gotos are no longer required
[ This is the fix for the issue that was reverted in commit
143c97cc6529, but this time without breaking 'pbuilder' due to
increased reference counts - Linus ]

Since we split the scsi_request out of struct request bsg fails to
provide a reply-buffer for the drivers. This was done via the pointer
for sense-data, that is not preallocated anymore.
Failing to allocate/assign it results in illegal dereferences because
LLDs use this pointer unquestioned.
An example panic on s390x, using the zFCP driver, looks like this (I had
debugging on, otherwise NULL-pointer dereferences wouldn't even panic on
s390x):
Unable to handle kernel pointer dereference in virtual kernel address space

Kernel panic - not syncing: Fatal exception in interrupt
This patch moves bsg-lib to allocate and setup struct bsg_job ahead of
time, including the allocation of a buffer for the reply-data.
This means, struct bsg_job is not allocated separately anymore, but as part
of struct request allocation - similar to struct scsi_cmd. Reflect this in
the function names that used to handle creation/destruction of struct
bsg_job.

The optimisation it does is broken when the 'new' register value has a
variable offset and the 'old' was constant. I broke it with my pointer
types unification (see Fixes tag below), before which the 'new' value
would have type PTR_TO_MAP_VALUE_ADJ and would thus not compare equal;
other changes in that patch mean that its original behaviour (ignore
min/max values) cannot be restored.
Tests on a sample set of cilium programs show no change in count of
processed instructions.

Rename skb_pad() into __skb_pad() and make it take a third argument:
free_on_error which controls whether kfree_skb() should be called or
not, skb_pad() directly makes use of it and passes true to preserve its

skb_put_padto().

This reverts commit c8c03f1858331e85d397bacccd34ef409aae993c.
It turns out that while fixing the ptmx file descriptor to have the
correct 'struct path' to the associated slave pty is a really good
thing, it breaks some user space tools for a very annoying reason.
The problem is that /dev/ptmx and its associated slave pty (/dev/pts/X)
are on different mounts. That was what caused us to have the wrong path
in the first place (we would mix up the vfsmount of the 'ptmx' node,
with the dentry of the pty slave node), but it also means that now while
we use the right vfsmount, having the pty master open also keeps the pts
mount busy.
And it turn sout that that makes 'pbuilder' very unhappy, as noted by
Stefan Lippers-Hollmann:
"This patch introduces a regression for me when using pbuilder
0.228.7[2] (a helper to build Debian packages in a chroot and to
create and update its chroots) when trying to umount /dev/ptmx (inside
the chroot) on Debian/ unstable (full log and pbuilder configuration
file[3] attached).
[...]
Setting up build-essential (12.3) ...
Processing triggers for libc-bin (2.24-15) ...
I: unmounting dev/ptmx filesystem
W: Could not unmount dev/ptmx: umount: /var/cache/pbuilder/build/1340/dev/ptmx: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)"
apparently pbuilder tries to unmount the /dev/pts filesystem while still
holding at least one master node open, which is arguably not very nice,
but we don't break user space even when fixing other bugs.
So this commit has to be reverted.
I'll try to figure out a way to avoid caching the path to the slave pty
in the master pty. The only thing that actually wants that slave pty
path is the "TIOCGPTPEER" ioctl, and I think we could just recreate the
path at that time.

This way we don't need a block_device structure to submit I/O. The
block_device has different life time rules from the gendisk and
request_queue and is usually only available when the block device node
is open. Other callers need to explicitly create one (e.g. the lightnvm
passthrough code, or the new nvme multipathing code).
For the actual I/O path all that we need is the gendisk, which exists
once per block device. But given that the block layer also does
partition remapping we additionally need a partition index, which is
used for said remapping in generic_make_request.
Note that all the block drivers generally want request_queue or
sometimes the gendisk, so this removes a layer of indirection all
over the stack.

Not a big pull request this time around. Only 49 non-merge
commits. This pull request is, however, all over the place. Most of
the changes are in the bdc driver adding support for USB Phy layer and
PM.
Renesas adds support for R-Car H3 ES2.0 and R-Car M3-W SoCs.
Also here is PM_RUNTIME support for dwc3-keystone.
UDC Core got a DMA unmap fix to make sure we only unmap requests that
were, indeed, mapped.
Other than these, we have a lot of cleanups, many of them adding

This was reported many times, and this was even mentioned in commit
52ee2dfdd4f5 ("pids: refactor vnr/nr_ns helpers to make them safe") but
somehow nobody bothered to fix the obvious problem: task_tgid_nr_ns() is
not safe because task->group_leader points to nowhere after the exiting
task passes exit_notify(), rcu_read_lock() can not help.
We really need to change __unhash_process() to nullify group_leader,
parent, and real_parent, but this needs some cleanups. Until then we
can turn task_tgid_nr_ns() into another user of __task_pid_nr_ns() and
fix the problem.

registered
Instead of the callsites choosing between of_cpu_device_node_get if the
CPUs are registered as of_node is populated by then and of_get_cpu_node
when the CPUs are not yet registered as CPU of_nodes are not yet stashed
thereby needing to parse the device tree, we can call of_get_cpu_node
in case the CPUs are not yet registered.
This will allow to use of_cpu_device_node_get anywhere hiding the
details from the caller.

Second set of IIO fixes for the 4.13 cycle.
Given the late stage of this series, some more involved fixes have been
held back for the upcoming merge window.
The hid-sensor issue has been causing problems for a long time so it
is great to have that one finally fixed! No more bug reports for the
userspace guys (well about that anyway).
* documentation
- some warning fixes due to missing colons in kernel-doc.
* adis16480
- fix accel scale factor.
* bmp280
- properly initialize the device for humidity readings - without this
the humidity readings may be skipped and a magic value of 0x8000 returned.
* hid-sensor-strigger
- fix a race with user space when powering up the sensor.
* ina291
- Avoid an underflow for the sleeping time as a result of supporting the
fastest rates.
* st-magnetometer
- Fix the status register address for hte LSM303AGR,
- Remove the ihl property for LSM303AGR as the sensor doesn't support
active low for the dataready line.
* stm32-adc
- Fix use of a common clock rate.
* stm32-timer
- fix the quadrature mode get routine to account for the magic 0 value.
set on boot.
- fix the return value of write_raw,
- fix the get/set down count direction as the enum value was not being
converted to the relevant bit field,
- add an enable attribute to actually turn it on when in encoder mode,
- missing mask when reading the trigger mode.

Jonathan writes:
Second set of IIO new device support, features and cleanup for the 4.14 cycle.
New device support:
* ak8974
- support the AMI306.
* st_magnetometer
- add support for the LIS2MDL with bindings.
* rockchip-saradc
- add binding for rv1108 SoC (no driver change).
* srf08
- add srf02 (i2c only) and srf10 support.
* stm32-timer
- support for the STM32H7 to existing driver.
Features:
* tools
- move over to the tools buildsystem rather than hand rolling.
- add an install section to the build.
* ak8974
- use serial number to add device randomness.
- add AMI306 calibration data output.
* ccs811
- triggered buffer support.
* srf08
- add a device tree table as the old style i2c probing is going away,
- add triggered buffer support
* st32-adc
- add optional st,min-sample-time-nsecs binding to allow control of
sampling against analog circuitry.
* stm32-timer
- add output compare triggers.
* ti-ads1015
- add threshold event support.
* ti-ads7950
- Allow use on ACPI platforms including providing a default reference
voltage as there is no way to obtain this on ACPI currently.
Cleanup and fixes:
* ad7606
- fix an error return code in probe.
* ads1015
- fix incorrect data rate setting update when capture in progress,
- fix wrong scale information for the ADS1115,
- make conversions work when CONFIG_PM is not set,
- make sure we don't get a stale result after a runtime resume by
ensuring we wait long enough,
- avoid returning a false error form the buffer setup callbacks,
- add enough wait time to get the correct conversion,
- remove an unnecessary config register update,
- add a helper to set conversion mode reducing repeated boilerplate,
- use devm_iio_triggered_buffer_setup to simplify error and remove
paths,
- use iio_device_claim_direct_mode instead of opencoding the same.
* ak8974
- mark the INT_CLEAR register as precious to prevent debugfs access.
* apds9300
- constify the i2c_device_id.
* at91-sama5 adc
- add missing Kconfig dependency.
* bma180 accel
- constify the i2c_device_id.
* rockchip_saradc
- explicitly request exclusive reset control as part of the reset rework
on going throughout the kernel.
* st_accel
- fix drdy configuration for a load of accelerometers that only have
the int1 line. Fix is unimportant as presumably no deviec tree actually
used the non existent hardware line.
* st_pressure
- fix drdy configuration for LPS22HB and LPS25H by dropping int2 support
as they don't have this. Fix is unimportant as presumably no device tree
actually used the non existent hardware line.
* stm32-dac
- explicitly request exclusive reset control (part of reset being reworked).
* tsl2583
- constify the i2c_device_id.
* xadc
- coding style fixes.

Pull watchdog fix from Thomas Gleixner:
"A fix for the hardlockup watchdog to prevent false positives with
extreme Turbo-Modes which make the perf/NMI watchdog fire faster than
the hrtimer which is used to verify.
Slightly larger than the minimal fix, which just would increase the
hrtimer frequency, but comes with extra overhead of more watchdog
timer interrupts and thread wakeups for all users.
With this change we restrict the overhead to the extreme Turbo-Mode
systems"
