02d5e01680 sound fixes for 5.15-rc4 
It became a slightly large collection of changes, partly because
 I've been off in the last weeks.  Most of changes are small and
 scattered while a bit big change is found in HD-audio Realtek
 codec driver; it's a very device-specific fix that has been long
 wanted, so I decided to pick up although it's in the middle RC.
 
 Some highlights:
 * A new guard ioctl for ALSA rawmidi API to avoid the misuse of
   the new timestamp framing mode; it's for a regression fix
 * HD-audio: a revert of the 5.15 change that might work badly,
   new quirks for Lenovo Legion & co, a follow-up fix for CS8409
 * ASoC: lots of SOF-related fixes, fsl component fixes, corrections of
   mediatek drivers
 * USB-audio: fix for the PM resume
 * FireWire: oxfw and motu fixes

4ca57d5139 habanalabs: fix resetting args in wait for CS IOCTL 
In wait for CS IOCTL code, the driver resets the incoming args structure
before returning to the user, regardless of the return value of the
IOCTL.

In case the IOCTL returns EINTR, resetting the args will result in error
in case the userspace will repeat the ioctl call immediately (which is
the behavior in the hl-thunk userspace library).

The solution is to reset the args only if the driver returns success (0)
as a return value for the IOCTL.

09d2317440 ALSA: rawmidi: introduce SNDRV_RAWMIDI_IOCTL_USER_PVERSION 
The new framing mode causes the user space regression, because
the alsa-lib code does not initialize the reserved space in
the params structure when the device is opened.

This change adds SNDRV_RAWMIDI_IOCTL_USER_PVERSION like we
do for the PCM interface for the protocol acknowledgment.

f8d858e607 xfrm: make user policy API complete 
>From a userland POV, this API was based on some magic values:
 - dirmask and action were bitfields but meaning of bits
   (XFRM_POL_DEFAULT_*) are not exported;
 - action is confusing, if a bit is set, does it mean drop or accept?

Let's try to simplify this uapi by using explicit field and macros.

844f7eaaed include/uapi/linux/xfrm.h: Fix XFRM_MSG_MAPPING ABI breakage 
Commit 2d151d3907 ("xfrm: Add possibility to set the default to block
if we have no policy") broke ABI by changing the value of the XFRM_MSG_MAPPING
enum item, thus also evading the build-time check
in security/selinux/nlmsgtab.c:selinux_nlmsg_lookup for presence of proper
security permission checks in nlmsg_xfrm_perms.  Fix it by placing
XFRM_MSG_SETDEFAULT/XFRM_MSG_GETDEFAULT to the end of the enum, right before
__XFRM_MSG_MAX, and updating the nlmsg_xfrm_perms accordingly.

b564171ade binder: fix freeze race 
Currently cgroup freezer is used to freeze the application threads, and
BINDER_FREEZE is used to freeze the corresponding binder interface.
There's already a mechanism in ioctl(BINDER_FREEZE) to wait for any
existing transactions to drain out before actually freezing the binder
interface.

But freezing an app requires 2 steps, freezing the binder interface with
ioctl(BINDER_FREEZE) and then freezing the application main threads with
cgroupfs. This is not an atomic operation. The following race issue
might happen.

1) Binder interface is frozen by ioctl(BINDER_FREEZE);
2) Main thread A initiates a new sync binder transaction to process B;
3) Main thread A is frozen by "echo 1 > cgroup.freeze";
4) The response from process B reaches the frozen thread, which will
unexpectedly fail.

This patch provides a mechanism to check if there's any new pending
transaction happening between ioctl(BINDER_FREEZE) and freezing the
main thread. If there's any, the main thread freezing operation can
be rolled back to finish the pending transaction.

Furthermore, the response might reach the binder driver before the
rollback actually happens. That will still cause failed transaction.

As the other process doesn't wait for another response of the response,
the response transaction failure can be fixed by treating the response
transaction like an oneway/async one, allowing it to reach the frozen
thread. And it will be consumed when the thread gets unfrozen later.

NOTE: This patch reuses the existing definition of struct
binder_frozen_status_info but expands the bit assignments of __u32
member sync_recv.

To ensure backward compatibility, bit 0 of sync_recv still indicates
there's an outstanding sync binder transaction. This patch adds new
information to bit 1 of sync_recv, indicating the binder transaction
happens exactly when there's a race.

If an existing userspace app runs on a new kernel, a sync binder call
will set bit 0 of sync_recv so ioctl(BINDER_GET_FROZEN_INFO) still
return the expected value (true). The app just doesn't check bit 1
intentionally so it doesn't have the ability to tell if there's a race.
This behavior is aligned with what happens on an old kernel which
doesn't set bit 1 at all.

A new userspace app can 1) check bit 0 to know if there's a sync binder
transaction happened when being frozen - same as before; and 2) check
bit 1 to know if that sync binder transaction happened exactly when
there's a race - a new information for rollback decision.

the same time, confirmed the pending transactions succeeded.

checkpatch complains about source files with filenames (e.g. in
these cases just below the SPDX header in comments at the top of
various files in fs/cifs). It also is helpful to change this now
so will be less confusing when the parent directory is renamed

c8a6153b6c vduse: Introduce VDUSE - vDPA Device in Userspace 
This VDUSE driver enables implementing software-emulated vDPA
devices in userspace. The vDPA device is created by
ioctl(VDUSE_CREATE_DEV) on /dev/vduse/control. Then a char device
interface (/dev/vduse/$NAME) is exported to userspace for device
emulation.

In order to make the device emulation more secure, the device's
control path is handled in kernel. A message mechnism is introduced
to forward some dataplane related control messages to userspace.

And in the data path, the DMA buffer will be mapped into userspace
address space through different ways depending on the vDPA bus to
which the vDPA device is attached. In virtio-vdpa case, the MMU-based
software IOTLB is used to achieve that. And in vhost-vdpa case, the
DMA buffer is reside in a userspace memory region which can be shared
to the VDUSE userspace processs via transferring the shmfd.

For more details on VDUSE design and usage, please see the follow-on
Documentation commit.

NB(mst): when merging this with
b542e383d8 ("eventfd: Make signal recursion protection a task bit")
replace eventfd_signal_count with eventfd_signal_allowed,
and drop the previous
("eventfd: Export eventfd_wake_count to modules").

c7c5e6ff53 fq_codel: reject silly quantum parameters 
syzbot found that forcing a big quantum attribute would crash hosts fast,
essentially using this:

tc qd replace dev eth0 root fq_codel quantum 4294967295

This is because fq_codel_dequeue() would have to loop
~2^31 times in :

	if (flow->deficit <= 0) {
		flow->deficit += q->quantum;
		list_move_tail(&flow->flowchain, &q->old_flows);
		goto begin;
	}

SFQ max quantum is 2^19 (half a megabyte)
Lets adopt a max quantum of one megabyte for FQ_CODEL.

b27abaccf8 mm/mempolicy: add MPOL_PREFERRED_MANY for multiple preferred nodes 
Patch series "Introduce multi-preference mempolicy", v7.

This patch series introduces the concept of the MPOL_PREFERRED_MANY
mempolicy.  This mempolicy mode can be used with either the
set_mempolicy(2) or mbind(2) interfaces.  Like the MPOL_PREFERRED
interface, it allows an application to set a preference for nodes which
will fulfil memory allocation requests.  Unlike the MPOL_PREFERRED mode,
it takes a set of nodes.  Like the MPOL_BIND interface, it works over a
set of nodes.  Unlike MPOL_BIND, it will not cause a SIGSEGV or invoke the
OOM killer if those preferred nodes are not available.

Along with these patches are patches for libnuma, numactl, numademo, and
memhog.  They still need some polish, but can be found here:
https://gitlab.com/bwidawsk/numactl/-/tree/prefer-many It allows new
usage: `numactl -P 0,3,4`

The goal of the new mode is to enable some use-cases when using tiered memory
usage models which I've lovingly named.

1a. The Hare - The interconnect is fast enough to meet bandwidth and
    latency requirements allowing preference to be given to all nodes with
    "fast" memory.
1b. The Indiscriminate Hare - An application knows it wants fast
    memory (or perhaps slow memory), but doesn't care which node it runs
    on.  The application can prefer a set of nodes and then xpu bind to
    the local node (cpu, accelerator, etc).  This reverses the nodes are
    chosen today where the kernel attempts to use local memory to the CPU
    whenever possible.  This will attempt to use the local accelerator to
    the memory.
2.  The Tortoise - The administrator (or the application itself) is
    aware it only needs slow memory, and so can prefer that.

Much of this is almost achievable with the bind interface, but the bind
interface suffers from an inability to fallback to another set of nodes if
binding fails to all nodes in the nodemask.

Like MPOL_BIND a nodemask is given. Inherently this removes ordering from the
preference.

> /* Set first two nodes as preferred in an 8 node system. */
> const unsigned long nodes = 0x3
> set_mempolicy(MPOL_PREFER_MANY, &nodes, 8);

> /* Mimic interleave policy, but have fallback *.
> const unsigned long nodes = 0xaa
> set_mempolicy(MPOL_PREFER_MANY, &nodes, 8);

Some internal discussion took place around the interface. There are two
alternatives which we have discussed, plus one I stuck in:

1. Ordered list of nodes.  Currently it's believed that the added
   complexity is nod needed for expected usecases.
2. A flag for bind to allow falling back to other nodes.  This
   confuses the notion of binding and is less flexible than the current
   solution.
3. Create flags or new modes that helps with some ordering.  This
   offers both a friendlier API as well as a solution for more customized
   usage.  It's unknown if it's worth the complexity to support this.
   Here is sample code for how this might work:

> // Prefer specific nodes for some something wacky
> set_mempolicy(MPOL_PREFER_MANY, 0x17c, 1024);
>
> // Default
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_SOCKET, NULL, 0);
> // which is the same as
> set_mempolicy(MPOL_DEFAULT, NULL, 0);
>
> // The Hare
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE, NULL, 0);
>
> // The Tortoise
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE_REV, NULL, 0);
>
> // Prefer the fast memory of the first two sockets
> set_mempolicy(MPOL_PREFER_MANY | MPOL_F_PREFER_ORDER_TYPE, -1, 2);
>

This patch (of 5):

The NUMA APIs currently allow passing in a "preferred node" as a single
bit set in a nodemask.  If more than one bit it set, bits after the first
are ignored.

This single node is generally OK for location-based NUMA where memory
being allocated will eventually be operated on by a single CPU.  However,
in systems with multiple memory types, folks want to target a *type* of
memory instead of a location.  For instance, someone might want some
high-bandwidth memory but do not care about the CPU next to which it is
allocated.  Or, they want a cheap, high capacity allocation and want to
target all NUMA nodes which have persistent memory in volatile mode.  In
both of these cases, the application wants to target a *set* of nodes, but
does not want strict MPOL_BIND behavior as that could lead to OOM killer
or SIGSEGV.

So add MPOL_PREFERRED_MANY policy to support the multiple preferred nodes
requirement.  This is not a pie-in-the-sky dream for an API.  This was a
response to a specific ask of more than one group at Intel.  Specifically:

1. There are existing libraries that target memory types such as
   https://github.com/memkind/memkind.  These are known to suffer from
   SIGSEGV's when memory is low on targeted memory "kinds" that span more
   than one node.  The MCDRAM on a Xeon Phi in "Cluster on Die" mode is an
   example of this.

2. Volatile-use persistent memory users want to have a memory policy
   which is targeted at either "cheap and slow" (PMEM) or "expensive and
   fast" (DRAM).  However, they do not want to experience allocation
   failures when the targeted type is unavailable.

3. Allocate-then-run.  Generally, we let the process scheduler decide
   on which physical CPU to run a task.  That location provides a default
   allocation policy, and memory availability is not generally considered
   when placing tasks.  For situations where memory is valuable and
   constrained, some users want to allocate memory first, *then* allocate
   close compute resources to the allocation.  This is the reverse of the
   normal (CPU) model.  Accelerators such as GPUs that operate on
   core-mm-managed memory are interested in this model.

A check is added in sanitize_mpol_flags() to not permit 'prefer_many'
policy to be used for now, and will be removed in later patch after all
implementations for 'prefer_many' are ready, as suggested by Michal Hocko.

a9c9a6f741 SCSI misc on 20210902 
This series consists of the usual driver updates (ufs, qla2xxx,
 target, smartpqi, lpfc, mpt3sas).  The core change causing the most
 churn was replacing the command request field request with a macro,
 allowing us to offset map to it and remove the redundant field; the
 same was also done for the tag field.  The most impactful change is
 the final removal of scsi_ioctl, which has been deprecated for over a
 decade.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:

 - Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
   scheduler changes merged via the tip tree).

 - More entry.S clean-ups and conversion to C.

 - MTE updates: allow a preferred tag checking mode to be set per CPU
   (the overhead of synchronous mode is smaller for some CPUs than
   others); optimisations for kernel entry/exit path; optionally disable
   MTE on the kernel command line.

 - Kselftest improvements for SVE and signal handling, PtrAuth.

 - Fix unlikely race where a TLBI could use stale ASID on an ASID
   roll-over (found by inspection).

 - Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher
   exception levels; drop unnecessary sigdelsetmask() call in the
   signal32 handling; remove BUG_ON when failing to allocate SVE state
   (just signal the process); SYM_CODE annotations.

 - Other trivial clean-ups: use macros instead of magic numbers, remove
   redundant returns, typos.

bcfeebbff3 Merge branch 'exit-cleanups-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace 
Pull exit cleanups from Eric Biederman:
 "In preparation of doing something about PTRACE_EVENT_EXIT I have
  started cleaning up various pieces of code related to do_exit. Most of
  that code I did not manage to get tested and reviewed before the merge
  window opened but a handful of very useful cleanups are ready to be
  merged.

  The first change is simply the removal of the bdflush system call. The
  code has now been disabled long enough that even the oldest userspace
  working userspace setups anyone can find to test are fine with the
  bdflush system call being removed.

  Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of
  calling do_exit directly is interesting only in that it is nearly the
  most difficult of the incorrect uses of do_exit to remove.

  The change to the seccomp code to simply send a signal instead of
  calling do_coredump directly is a very nice little cleanup made
  possible by realizing the existing signal sending helpers were missing
  a little bit of functionality that is easy to provide"

Pull siginfo si_trapno updates from Eric Biederman:
 "The full set of si_trapno changes was not appropriate as a fix for the
  newly added SIGTRAP TRAP_PERF, and so I postponed the rest of the
  related cleanups.

  This is the rest of the cleanups for si_trapno that reduces it from
  being a really weird arch special case that is expect to be always
  present (but isn't) on the architectures that support it to being yet
  another field in the _sigfault union of struct siginfo.

  The changes have been reviewed and marinated in linux-next. With the
  removal of this awkward special case new code (like SIGTRAP TRAP_PERF)
  that works across architectures should be easier to write and
  maintain"

 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

4cd67adc44 This tag contains habanalabs driver changes for v5.15: 
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
   signals and signal them from within its workloads, while the driver
   performs the waiting. This allows finer granularity of pipelining
   between the different engines and resource utilization.
 
 - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
   on multiple command submissions (workloads) at the same time. This
   is an optimization for the user process so it won't need to call
   multiple times to the wait_for_cs ioctl.
 
 - Add new feature of "state dump", which can be triggered through new
   debugfs node. This is a similar concept to the kernel panic dump.
   This new mechanism retrieves information from the device in case
   one of the workloads that was sent by the user got stuck. This is
   very helpful for debugging the hang.
 
 - Add a new debugfs node to perform lookup of user pointers that are
   mapped to habana device's pmmu.
 
 - Fix to the tracking of user process when running inside a container.
 
 - Allow user to map more than 4GB of memory to the device MMU in single
   IOCTL call.
 
 - Minimize number of register reads done in GAUDI during user operation.
 
 - Allow user to retrieve the device's server type that the device is
   connected to.
 
 - Several fixes to the code of waiting on interrupts on behalf of the
   user.
 
 - Fixes and improvements to the hint mechanism in our VA allocation.
 
 - Update the firmware header files to the latest version while
   maintaining backward compatibility with older firmware versions.
 
 - Multiple fixes to various bugs.

0d290223a6 sound updates for 5.15-rc1 
There are a few intensive changes in ALSA core side at this time that
 helped the significant code reduction.  Meanwhile we keep getting new
 stuff, so the total size still grows...
 Anyway, the below are some highlights in this development cycle.
 
 ALSA core:
 - New helpers to manage page allocations and card object with devres
 - Refactoring for memory allocation with wc-pages
 - A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for controlling
   the explicit sync of the stream control; it'll be used for ASoC SOF
   and non-coherent memory in future
 
 ASoC:
 - Lots of cleanups and improvements to the Intel drivers, including
   some new systems support
 - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195,
   Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L,
   Rockchip RK3568 S/PDIF
 
 USB-audio:
 - Re-organized the quirk handling and  a new option quirk_flags
 - Fix for a regression in 5.14 code change for JACK
 - Quirks for Sony WALKMAN, Digidesign mbox
 
 HD-audio:
 - Enhanced support for CS8409 codec
 - More consistent shutdown behavior with the runtime PM
 - The model option can accept the PCI or codec SSID as an alias
 - Quirks for ASUS ROG, HP Spectre x360
 
 Others:
 - Lots of code reduction in legacy drivers with devres helpers
 - FireWire MOTU 896HD support

71731090ab habanalabs: add "in device creation" status 
On init, the disabled state is cleared right before hw_init and that
causes the device to report on "Operational" state before the device
initialization is finished. Although the char device is not yet exposed
to the user at this stage, the sysfs entries are exposed.

This can cause errors in monitoring applications that use the sysfs
entries.

In order to avoid this, a new state "in device creation" is introduced
to ne reported when the device is not disabled but is still in init
flow.

5dc9ffaff1 habanalabs: expose server type in INFO IOCTL 
Add the server type property to the hl_info_hw_ip_info structure
that is exposed to the user via the INFO IOCTL.

This is needed by the userspace s/w stack to know the connections map
of the internal links that connect the ASIC among themselves inside the
server.

The F/W will tell us, as part of the NIC information, the server type
that the GAUDI is located in.
