Pull AFS updates from David Howells:
"Use the new netfs lib.
Begin the process of overhauling the use of the fscache API by AFS and
the introduction of support for features such as Transparent Huge
Pages (THPs).
- Add some support for THPs, including using core VM helper functions
to find details of pages.
- Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
as this handles THPs and doesn't require allocation of large bvec
arrays.
- Delegate address_space read/pre-write I/O methods for AFS to the
netfs helper library. A method is provided to the library that
allows it to issue a read against the server.
This includes a change in use for PG_fscache (it now indicates a
DIO write in progress from the marked page), so a number of waits
need to be deployed for it.
- Split the core AFS writeback function to make it easier to modify
in future patches to handle writing to the cache. [This might
feasibly make more sense moved out into my fscache-iter branch].
I've tested these with "xfstests -g quick" against an AFS volume
(xfstests needs patching to make it work). With this, AFS without a
cache passes all expected xfstests; with a cache, there's an extra
failure, but that's also there before these patches. Fixing that
probably requires a greater overhaul (as can be found on my
fscache-iter branch, but that's for a later time).
Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
exercising the patches in their test farm also"

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull network filesystem helper library updates from David Howells:
"Here's a set of patches for 5.13 to begin the process of overhauling
the local caching API for network filesystems. This set consists of
two parts:
(1) Add a helper library to handle the new VM readahead interface.
This is intended to be used unconditionally by the filesystem
(whether or not caching is enabled) and provides a common
framework for doing caching, transparent huge pages and, in the
future, possibly fscrypt and read bandwidth maximisation. It also
allows the netfs and the cache to align, expand and slice up a
read request from the VM in various ways; the netfs need only
provide a function to read a stretch of data to the pagecache and
the helper takes care of the rest.
(2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
facility to do async DIO to transfer data to/from the netfs's
pages, rather than using readpage with wait queue snooping on one
side and vfs_write() on the other. It also uses less memory, since
it doesn't do buffered I/O on the backing file.
Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
available to be read from the cache. Whilst this is an improvement
from the bmap interface, it still has a problem with regard to a
modern extent-based filesystem inserting or removing bridging
blocks of zeros. Fixing that requires a much greater overhaul.
This is a step towards overhauling the fscache API. The change is
opt-in on the part of the network filesystem. A netfs should not try
to mix the old and the new API because of conflicting ways of handling
pages and the PG_fscache page flag and because it would be mixing DIO
with buffered I/O. Further, the helper library can't be used with the
old API.
This does not change any of the fscache cookie handling APIs or the
way invalidation is done at this time.
In the near term, I intend to deprecate and remove the old I/O API
(fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
fscache_write_page() and fscache_uncache_page()) and eventually
replace most of fscache/cachefiles with something simpler and easier
to follow.
This patchset contains the following parts:
- Some helper patches, including provision of an ITER_XARRAY iov
iterator and a function to do readahead expansion.
- Patches to add the netfs helper library.
- A patch to add the fscache/cachefiles kiocb API.
- A pair of patches to fix some review issues in the ITER_XARRAY and
read helpers as spotted by Al and Willy.
Jeff Layton has patches to add support in Ceph for this that he
intends for this merge window. I have a set of patches to support AFS
that I will post a separate pull request for.
With this, AFS without a cache passes all expected xfstests; with a
cache, there's an extra failure, but that's also there before these
patches. Fixing that probably requires a greater overhaul. Ceph also
passes the expected tests.
I also have patches in a separate branch to tidy up the handling of
PG_fscache/PG_private_2 and their contribution to page refcounting in
the core kernel here, but I haven't included them in this set and will
route them separately"

vfio/gvt: fix DRM_I915_GVT dependency on VFIO_MDEV
The Kconfig dependency is incomplete since DRM_I915_GVT is a 'bool' symbol that depends on the 'tristate' VFIO_MDEV. This allows a configuration with VFIO_MDEV=m, DRM_I915_GVT=y and DRM_I915=y that causes a link failure: x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `available_instances_show': gvt.c:(.text+0x67a): undefined reference to `mtype_get_parent_dev' x86_64-linux-ld: gvt.c:(.text+0x6a5): undefined reference to `mtype_get_type_group_id' x86_64-linux-ld: drivers/gpu/drm/i915/gvt/gvt.o: in function `description_show': gvt.c:(.text+0x76e): undefined reference to `mtype_get_parent_dev' x86_64-linux-ld: gvt.c:(.text+0x799): undefined reference to `mtype_get_type_group_id' Clarify the dependency by specifically disallowing the broken configuration. If VFIO_MDEV is built-in, it will work, but if VFIO_MDEV=m, the i915 driver cannot be built-in here. Fixes: |

netfilter: nftables: add catch-all set element support
This patch extends the set infrastructure to add a special catch-all set element. If the lookup fails to find an element (or range) in the set, then the catch-all element is selected. Users can specify a mapping, expression(s) and timeout to be attached to the catch-all element. This patch adds a catchall list to the set, this list might contain more than one single catch-all element (e.g. in case that the catch-all element is removed and a new one is added in the same transaction). However, most of the time, there will be either one element or no elements at all in this list. The catch-all element is identified via NFT_SET_ELEM_CATCHALL flag and such special element has no NFTA_SET_ELEM_KEY attribute. There is a new nft_set_elem_catchall object that stores a reference to the dummy catch-all element (catchall->elem) whose layout is the same of the set element type to reuse the existing set element codebase. The set size does not apply to the catch-all element, users can define a catch-all element even if the set is full. The check for valid set element flags hava been updates to report EOPNOTSUPP in case userspace requests flags that are not supported when using new userspace nftables and old kernel.

cfg80211: fix locking in netlink owner interface destruction
Harald Arnesen reported [1] a deadlock at reboot time, and after
he captured a stack trace a picture developed of what's going on:
The distribution he's using is using iwd (not wpa_supplicant) to
manage wireless. iwd will usually use the "socket owner" option
when it creates new interfaces, so that they're automatically
destroyed when it quits (unexpectedly or otherwise). This is also
done by wpa_supplicant, but it doesn't do it for the normal one,
only for additional ones, which is different with iwd.
Anyway, during shutdown, iwd quits while the netdev is still UP,
i.e. IFF_UP is set. This causes the stack trace that Linus so
nicely transcribed from the pictures:
cfg80211_destroy_iface_wk() takes wiphy_lock
-> cfg80211_destroy_ifaces()
->ieee80211_del_iface
->ieeee80211_if_remove
->cfg80211_unregister_wdev
->unregister_netdevice_queue
->dev_close_many
->__dev_close_many
->raw_notifier_call_chain
->cfg80211_netdev_notifier_call
and that last call tries to take wiphy_lock again.

powerpc/papr_scm: Mark nvdimm as unarmed if needed during probe
In case an nvdimm is found to be unarmed during probe then set its NDD_UNARMED flag before nvdimm_create(). This would enforce a read-only access to the ndimm region. Presently even if an nvdimm is unarmed its not marked as read-only on ppc64 guests. The patch updates papr_scm_nvdimm_init() to force query of nvdimm health via __drc_pmem_query_health() and if nvdimm is found to be unarmed then set the nvdimm flag ND_UNARMED for nvdimm_create().

io_uring: maintain drain logic for multishot poll requests
Now that we have multishot poll requests, one SQE can emit multiple
CQEs. given below example:
sqe0(multishot poll)-->sqe1-->sqe2(drain req)
sqe2 is designed to issue after sqe0 and sqe1 completed, but since sqe0
is a multishot poll request, sqe2 may be issued after sqe0's event
triggered twice before sqe1 completed. This isn't what users leverage
drain requests for.
Here the solution is to wait for multishot poll requests fully
completed.
To achieve this, we should reconsider the req_need_defer equation, the
original one is:
all_sqes(excluding dropped ones) == all_cqes(including dropped ones)
This means we issue a drain request when all the previous submitted
SQEs have generated their CQEs.
Now we should consider multishot requests, we deduct all the multishot
CQEs except the cancellation one, In this way a multishot poll request
behave like a normal request, so:
all_sqes == all_cqes - multishot_cqes(except cancellations)
Here we introduce cq_extra for it.

io_uring: Check current->io_uring in io_uring_cancel_sqpoll
syzkaller identified KASAN: null-ptr-deref Write in io_uring_cancel_sqpoll. io_uring_cancel_sqpoll is called by io_sq_thread before calling io_uring_alloc_task_context. This leads to current->io_uring being NULL. io_uring_cancel_sqpoll should not have to deal with threads where current->io_uring is NULL. In order to cast a wider safety net, perform input sanitisation directly in io_uring_cancel_sqpoll and return for NULL value of current->io_uring. This is safe since if current->io_uring isn't set, then there's no way for the task to have submitted any requests.

exfat: speed up iterate/lookup by fixing start point of traversing cluster chain
When directory iterate and lookup is called, there's a buggy rewinding of start point for traversing cluster chain to the parent directory entry's first cluster. This caused repeated cluster chain traversing from the first entry of the parent directory that would show worse performance if huge amounts of files exist under the parent directory. Fix not to rewind, make continue from currently referenced cluster and dir entry.

Merge branch 'CO-RE relocation selftests fixes'
Andrii Nakryiko says: ==================== Lorenz Bauer noticed that core_reloc selftest has two inverted CHECK() conditions, allowing failing tests to pass unnoticed. Fixing that opened up few long-standing (field existence and direct memory bitfields) and one recent failures (BTF_KIND_FLOAT relos). This patch set fixes core_reloc selftest to capture such failures reliably in the future. It also fixes all the newly failing tests. See individual patches for details. This patch set also completes a set of ASSERT_xxx() macros, so now there should be a very little reason to use verbose and error-prone generic CHECK() macro. v1->v2: - updated bpf_core_fields_are_compat() comment to mention FLOAT (Lorenz).

selftests/bpf: Fix field existence CO-RE reloc tests
Negative field existence cases for have a broken assumption that FIELD_EXISTS
CO-RE relo will fail for fields that match the name but have incompatible type
signature. That's not how CO-RE relocations generally behave. Types and fields
that match by name but not by expected type are treated as non-matching
candidates and are skipped. Error later is reported if no matching candidate
was found. That's what happens for most relocations, but existence relocations
(FIELD_EXISTS and TYPE_EXISTS) are more permissive and they are designed to
return 0 or 1, depending if a match is found. This allows to handle
name-conflicting but incompatible types in BPF code easily. Combined with
___flavor suffixes, it's possible to handle pretty much any structural type
changes in kernel within the compiled once BPF source code.
So, long story short, negative field existence test cases are invalid in their
assumptions, so this patch reworks them into a single consolidated positive
case that doesn't match any of the fields.

selftests/bpf: Fix BPF_CORE_READ_BITFIELD() macro
Fix BPF_CORE_READ_BITFIELD() macro used for reading CO-RE-relocatable
bitfields. Missing breaks in a switch caused 8-byte reads always. This can
confuse libbpf because it does strict checks that memory load size corresponds
to the original size of the field, which in this case quite often would be
wrong.
After fixing that, we run into another problem, which quite subtle, so worth
documenting here. The issue is in Clang optimization and CO-RE relocation
interactions. Without that asm volatile construct (also known as
barrier_var()), Clang will re-order BYTE_OFFSET and BYTE_SIZE relocations and
will apply BYTE_OFFSET 4 times for each switch case arm. This will result in
the same error from libbpf about mismatch of memory load size and original
field size. I.e., if we were reading u32, we'd still have *(u8 *), *(u16 *),
*(u32 *), and *(u64 *) memory loads, three of which will fail. Using
barrier_var() forces Clang to apply BYTE_OFFSET relocation first (and once) to
calculate p, after which value of p is used without relocation in each of
switch case arms, doing appropiately-sized memory load.
Here's the list of relevant relocations and pieces of generated BPF code
before and after this patch for test_core_reloc_bitfields_direct selftests.

libbpf: Support BTF_KIND_FLOAT during type compatibility checks in CO-RE
Add BTF_KIND_FLOAT support when doing CO-RE field type compatibility check.
Without this, relocations against float/double fields will fail.
Also adjust one error message to emit instruction index instead of less
convenient instruction byte offset.

selftests/bpf: Add remaining ASSERT_xxx() variants
Add ASSERT_TRUE/ASSERT_FALSE for conditions calculated with custom logic to true/false. Also add remaining arithmetical assertions: - ASSERT_LE -- less than or equal; - ASSERT_GT -- greater than; - ASSERT_GE -- greater than or equal. This should cover most scenarios where people fall back to error-prone CHECK()s. Also extend ASSERT_ERR() to print out errno, in addition to direct error. Also convert few CHECK() instances to ensure new ASSERT_xxx() variants work as expected. Subsequent patch will also use ASSERT_TRUE/ASSERT_FALSE more extensively.

We added the include of book3s/64/pkeys.h for pte_to_hpte_pkey_bits(),
but that header on its own should only be included when PPC_MEM_KEYS=y.
Instead include linux/pkeys.h, which brings in the right definitions
when PPC_MEM_KEYS=y and also provides empty stubs when PPC_MEM_KEYS=n.

spi: Updates for v5.13
The only core work for SPI this time around is the completion of the
conversion to the new style method for specifying transfer delays,
meaning we can cope with what most controllers support more directly
using conversions in the core rather than open coding in drivers.
Otherwise it's a good stack of cleanups and fixes plus a few new
drivers.
The conversion to new style transfer delay will cause an issue with a
newly added staging driver which has a straightforward resolution in
-next.
- Completion of the conversion to new style transfer delay
configuration.
- Introduction and use of module_parport_driver() helper, merged here
as there's no parport tree.
- Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
MediaTek MT8195,

netfs: Miscellaneous fixes
Fix some miscellaneous things in the new netfs lib[1]:
(1) The kerneldoc for netfs_readpage() shouldn't say netfs_page().
(2) netfs_readpage() can get an integer overflow on 32-bit when it
multiplies page_index(page) by PAGE_SIZE. It should use
page_file_offset() instead.
(3) netfs_write_begin() should use page_offset() to avoid the same
overflow.
Note that netfs_readpage() needs to use page_file_offset() rather than
page_offset() as it may see swap-over-NFS.

hwmon updates for v5.13
The most notable change is the removal of the amd_energy driver. It was
rendered all but unusable by making its attributes privileged-only to work
around a security issue. A suggested remedy was rejected by AMD, so the
only real solution was to remove the driver. For the future, we'll have
to make sure that no privileged-access-only drivers are accepted into the
hwmon subsystem in the first place. The hwmon ABI document was updated
accordingly.
Other changes:
PMBus drivers:
- Added driver for MAX15301
- Added driver for BluTek BPA-RS600
- Added driver for fsp-3y PSUs and PDUs
- Added driver for Infineon IR36021
- Added driver for ST STPDDC60
- Added support for TI TPS53676 to tps53679 driver
- Introduced PMBUS symbol namespace
This was made necessary by a suggestion to use its exported functions
from outside the hwmon subsystem.
- Minor improvements and bug fixes
New drivers:
- Driver for NZXT Kraken X42/X52/X62/X72
Driver enhancements:
- Added support for Intel D5005 to intel-m10-bmc-hwmon driver
- Added support for NCT6686D to nct6683 driver
Other:
- Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
- Added support for fan drawers capability and present registers to mlxreg-fan
driver
- Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
- Replaced snprintf in show functions with sysfs_emit
Done with coccinelle script for all drivers to preempt endless per-driver
submissions of the same change.
- Use kobj_to_dev()
Another coccinelle based change to preempt endless per-driver submissions
of the same change.
- Various minor fixes and improvements

Merge tag 'hwmon-for-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon updates from Guenter Roeck:
"The most notable change is the removal of the amd_energy driver. It
was rendered all but unusable by making its attributes privileged-only
to work around a security issue. A suggested remedy was rejected by
AMD, so the only real solution was to remove the driver. For the
future, we'll have to make sure that no privileged-access-only drivers
are accepted into the hwmon subsystem in the first place. The hwmon
ABI document was updated accordingly.
Other changes:
PMBus drivers:
- Added driver for MAX15301
- Added driver for BluTek BPA-RS600
- Added driver for fsp-3y PSUs and PDUs
- Added driver for Infineon IR36021
- Added driver for ST STPDDC60
- Added support for TI TPS53676 to tps53679 driver
- Introduced PMBUS symbol namespace. This was made necessary by a
suggestion to use its exported functions from outside the hwmon
subsystem.
- Minor improvements and bug fixes
New drivers:
- Driver for NZXT Kraken X42/X52/X62/X72
Driver enhancements:
- Added support for Intel D5005 to intel-m10-bmc-hwmon driver
- Added support for NCT6686D to nct6683 driver
Other:
- Converted sch5627 and amd9240 drivers to
hwmon_device_register_with_info()
- Added support for fan drawers capability and present registers to
mlxreg-fan driver
- Added Dell Latitude E7440 to fan control whitelist in dell-smm
driver
- Replaced snprintf in show functions with sysfs_emit. Done with
coccinelle script for all drivers to preempt endless per-driver
submissions of the same change.
- Use kobj_to_dev(). Another coccinelle based change to preempt
endless per-driver submissions of the same change.
- Various minor fixes and improvements"
