Pull USB/Thunderbolt/PHY driver updates from Greg KH:
"Here is the big USB and Thunderbolt and PHY driver updates for
5.6-rc1.
With the advent of USB4, "Thunderbolt" has really become USB4, so the
renaming of the Kconfig option and starting to share subsystem code
has begun, hence both subsystems coming in through the same tree here.
PHY driver updates also touched USB drivers, so that is coming in
through here as well.
Major stuff included in here are:
- USB 4 initial support added (i.e. Thunderbolt)
- musb driver updates
- USB gadget driver updates
- PHY driver updates
- USB PHY driver updates
- lots of USB serial stuff fixed up
- USB typec updates
- USB-IP fixes
- lots of other smaller USB driver updates
All of these have been in linux-next for a while now (the usb-serial
tree is already tested in linux-next on its own before merged into
here), with no reported issues"

Core changes:
- Dropped the chained IRQ setup callback into GPIOLIB as we got rid
of the last users of that in this changeset.
New drivers:
- New driver for Ingenic X1830.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.6 kernel cycle.
This is a pretty calm cycle so far, nothing special going on really.
Some more changes will come in from the irqchip and pin control trees.
I also deleted an orphan include file for FMC that was dangling since
subsystem was removed.
Core changes:
- Document the usecases for the kernelspace vs userspace handling of
GPIOs.
- Handle MSI (message signalled interrupts) properly in the core
hierarchical irqdomain code.
- Fix a rare race condition while initializing the descriptor array.
New drivers:
- Xylon LogiCVC GPIO driver.
- WDC934x GPIO controller driver.
Driver improvements:
- Implemented suspend/resume in the Tegra driver.
- MPC8xx edge detection fixup.
- Properly convert ThunderX to use hierarchical irqdomain with
GPIOLIB_IRQCHIP on top of the revert of the previous buggy
switchover. This time it works (hopefully).
Misc:
- Drop a FMC remnant file <linux/ipmi-fru.h>

====================
mptcp: fix sockopt crash and lockdep splats
Christoph Paasch reported a few bugs and lockdep splats triggered by
syzkaller.
One patch fixes a crash in set/getsockopt.
Two patches fix lockdep splats related to the order in which RTNL
and socket lock are taken.
Last patch fixes out-of-bounds access when TCP syncookies are used.
Change since last iteration on mptcp-list:
- add needed refcount in patch 2
- call tcp_get/setsockopt directly in patch 2
Other patches unchanged except minor amends to commit messages.

We can't deal with syncookie mode yet, the syncookie rx path will create
tcp reqsk, i.e. we get OOB access because we treat tcp reqsk as mptcp reqsk one:
TCP: SYN flooding on port 20002. Sending cookies.

tcp_v6_cookie_check net/ipv6/tcp_ipv6.c:1123 [inline]
[..]
Bug can be reproduced via "sysctl net.ipv4.tcp_syncookies=2".
Note that MPTCP should work with syncookies (4th ack would carry needed
state), but it appears better to sort that out in -next so do tcp
fallback for now.
I removed the MPTCP ifdef for tcp_rsk "is_mptcp" member because
if (IS_ENABLED()) is easier to read than "#ifdef IS_ENABLED()/#endif" pair.

but task is already holding lock:

which lock already depends on the new lock.

The trigger is:

setsockopt(4, SOL_IP, MCAST_JOIN_GROUP, {gr_interface=7, gr_group={sa_family=AF_INET, sin_port=htons(20003), sin_addr=inet_addr("224.0.0.2")}}, 136) = 0
exit(0)
Which results in a call to rtnl_lock while we are holding
the parent mptcp socket lock via
mptcp_close -> lock_sock(msk) -> inet_release -> ip_mc_drop_socket -> rtnl_lock().
>From lockdep point of view we thus have both
'rtnl_lock; lock_sock' and 'lock_sock; rtnl_lock'.
Fix this by stealing the msk conn_list and doing the subflow close
without holding the msk lock.

other info that might help us debug this:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(sk_lock-AF_INET);
lock(rtnl_mutex);
lock(sk_lock-AF_INET);
lock(rtnl_mutex);
The lockdep complaint is because we hold mptcp socket lock when calling
the sk_prot get/setsockopt handler, and those might need to acquire the
rtnl mutex. Normally, order is:
rtnl_lock(sk) -> lock_sock
Whereas for mptcp the order is
lock_sock(mptcp_sk) rtnl_lock -> lock_sock(subflow_sk)
We can avoid this by releasing the mptcp socket lock early, but, as Paolo
points out, we need to get/put the subflow socket refcount before doing so
to avoid race with concurrent close().

access to msk->cached_ext is only legal if the msk is locked or all
concurrent accesses are impossible.
Furthermore, once we start to tear down, we must make sure nothing else

The implementations for most channel types contains a map of methods to
priv registers in order to provide debugging info when a disp exception
has been raised.
This info is missing from the implementation of PIO channels as they're
rather simplistic already, however, if an exception is raised by one of
them, we'd end up triggering a NULL-pointer deref. Not ideal...

This patch adds the support for the notification of HD-audio hotplug
via the already existing drm_audio_component framework. This allows
us more reliable hotplug notification and ELD transfer without
accessing HD-audio bus; it's more efficient, and more importantly, it
works without waking up the runtime PM.
The implementation is rather simplistic: nouveau driver provides the
get_eld ops for HD-audio, and it notifies the audio hotplug via
pin_eld_notify callback upon each nv50_audio_enable() and _disable()
call. As the HD-audio pin assignment seems corresponding to the CRTC,
the crtc->index number is passed directly as the zero-based port
number.
The bind and unbind callbacks handle the device-link so that it
assures the PM call order.

Pull IMA updates from Mimi Zohar:
"Two new features - measuring certificates and querying IMA for a file

- Measuring certificates is like the rest of IMA, based on policy,
but requires loading a custom policy. Certificates loaded onto a
keyring, for example during early boot, before a custom policy has
been loaded, are queued and only processed after loading the custom
policy.
- IMA calculates and caches files hashes. Other kernel subsystems,
and possibly kernel modules, are interested in accessing these
cached file hashes.
The bug fixes prevent classifying a file short read (e.g. shutdown) as
an invalid file signature, add a missing blank when displaying the
securityfs policy rules containing LSM labels, and, lastly, fix the
handling of the IMA policy information for unknown LSM labels"

For personalities previously registered via IORING_REGISTER_PERSONALITY,
allow any command to select them. This is done through setting
sqe->personality to the id returned from registration, and then flagging
sqe->flags with IOSQE_PERSONALITY.

If an application wants to use a ring with different kinds of
credentials, it can register them upfront. We don't lookup credentials,
the credentials of the task calling IORING_REGISTER_PERSONALITY is used.
An 'id' is returned for the application to use in subsequent personality
support.

If IORING_SETUP_ATTACH_WQ is set, it expects wq_fd in io_uring_params to
be a valid io_uring fd io-wq of which will be shared with the newly
created io_uring instance. If the flag is set but it can't share io-wq,
it fails.
This allows creation of "sibling" io_urings, where we prefer to keep the
SQ/CQ private, but want to share the async backend to minimize the amount
of overhead associated with having multiple rings that belong to the same
backend.

Export a helper to attach to an existing io-wq, rather than setting up

We currently setup the io_wq with a static set of mm and creds. Even for
a single-use io-wq per io_uring, this is suboptimal as we have may have
multiple enters of the ring. For sharing the io-wq backend, it doesn't
work at all.
Switch to passing in the creds and mm when the work item is setup. This
means that async work is no longer deferred to the io_uring mm and creds,
it is done with the current mm and creds.
Flag this behavior with IORING_FEAT_CUR_PERSONALITY, so applications know
they can rely on the current personality (mm and creds) being the same
for direct issue and async issue.

"As the diffstat shows we've had again a lot of works done for this
cycle: the majority of changes are the continued componentization and
code refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI; some ioctls have been
extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers; the API
itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers; now
including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,

Pull btrfs updates from David Sterba:
"Features, highlights:
- async discard
- "mount -o discard=async" to enable it
- freed extents are not discarded immediatelly, but grouped
together and trimmed later, with IO rate limiting
- the "sync" mode submits short extents that could have been
ignored completely by the device, for SATA prior to 3.1 the
requests are unqueued and have a big impact on performance
- the actual discard IO requests have been moved out of
transaction commit to a worker thread, improving commit latency
- IO rate and request size can be tuned by sysfs files, for now
enabled only with CONFIG_BTRFS_DEBUG as we might need to
add/delete the files and don't have a stable-ish ABI for
general use, defaults are conservative
- export device state info in sysfs, eg. missing, writeable
- no discard of extents known to be untouched on disk (eg. after
reservation)
- device stats reset is logged with process name and PID that called
the ioctl
Fixes:
- fix missing hole after hole punching and fsync when using NO_HOLES
- writeback: range cyclic mode could miss some dirty pages and lead
to OOM
- two more corner cases for metadata_uuid change after power loss
during the change
- fix infinite loop during fsync after mix of rename operations
Core changes:
- qgroup assign returns ENOTCONN when quotas not enabled, used to
return EINVAL that was confusing
- device closing does not need to allocate memory anymore
- snapshot aware code got removed, disabled for years due to
performance problems, reimplmentation will allow to select wheter
defrag breaks or does not break COW on shared extents
- tree-checker:
- check leaf chunk item size, cross check against number of
stripes
- verify location keys for DIR_ITEM, DIR_INDEX and XATTR items
- new self test for physical -> logical mapping code, used for super
block range exclusion

test.d/ftrace/func-filter-glob.tc is failing on s390 because it has
ARCH_INLINE_SPIN_LOCK and friends set to 'y'. So the usual
__raw_spin_lock symbol isn't in the ftrace function list. Change
'*aw*lock' to '*spin*lock' which would hopefully match some of the
locking functions on all platforms.
