RDMA 5.8 merge window pull request
A few large, long discussed works this time. The RNBD block driver has
been posted for nearly two years now, and the removal of FMR has been a
recurring discussion theme for a long time. The usual smattering of
features and bug fixes.
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and a
mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block RDMA
device specific to ionos's cloud environment. It brings strong multipath
and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs and
drivers. FRWR should be preferred for at least a decade now.

exec: open code copy_string_kernel
Currently copy_string_kernel is just a wrapper around copy_strings that simplifies the calling conventions and uses set_fs to allow passing a kernel pointer. But due to the fact the we only need to handle a single kernel argument pointer, the logic can be sigificantly simplified while getting rid of the set_fs.

This allows people to actually use mount options with proc with no fear of messing up another mount of proc. Given the kernel's internal mounts of proc for things like uml this was a real problem, and resulted in Android's hidepid mount options being ignored and introducing security issues. The rest of the changes are small cleanups and fixes that came out of my work to allow this change to proc.

hugetlbfs: get unmapped area below TASK_UNMAPPED_BASE for hugetlbfs
In a 32-bit program, running on arm64 architecture. When the address space below mmap base is completely exhausted, shmat() for huge pages will return ENOMEM, but shmat() for normal pages can still success on no-legacy mode. This seems not fair. For normal pages, the calling trace of get_unmapped_area() is: => mm->get_unmapped_area() if on legacy mode, => arch_get_unmapped_area() => vm_unmapped_area() if on no-legacy mode, => arch_get_unmapped_area_topdown() => vm_unmapped_area() For huge pages, the calling trace of get_unmapped_area() is: => file->f_op->get_unmapped_area() => hugetlb_get_unmapped_area() => vm_unmapped_area() To solve this issue, we only need to make hugetlb_get_unmapped_area() take the same way as mm->get_unmapped_area(). Add *bottomup() and *topdown() for hugetlbfs, and check current mm->get_unmapped_area() to decide which one to use. If mm->get_unmapped_area is equal to arch_get_unmapped_area_topdown(), hugetlb_get_unmapped_area() calls topdown routine, otherwise calls bottomup routine.

Pull thread updates from Christian Brauner:
"We have been discussing using pidfds to attach to namespaces for quite
a while and the patches have in one form or another already existed
for about a year. But I wanted to wait to see how the general api
would be received and adopted.
This contains the changes to make it possible to use pidfds to attach
to the namespaces of a process, i.e. they can be passed as the first
argument to the setns() syscall.
When only a single namespace type is specified the semantics are
equivalent to passing an nsfd. That means setns(nsfd, CLONE_NEWNET)
equals setns(pidfd, CLONE_NEWNET).
However, when a pidfd is passed, multiple namespace flags can be
specified in the second setns() argument and setns() will attach the
caller to all the specified namespaces all at once or to none of them.
Specifying 0 is not valid together with a pidfd. Here are just two
obvious examples:
setns(pidfd, CLONE_NEWPID | CLONE_NEWNS | CLONE_NEWNET);
setns(pidfd, CLONE_NEWUSER);
Allowing to also attach subsets of namespaces supports various
use-cases where callers setns to a subset of namespaces to retain
privilege, perform an action and then re-attach another subset of
namespaces.
Apart from significantly reducing the number of syscalls needed to
attach to all currently supported namespaces (eight "open+setns"
sequences vs just a single "setns()"), this also allows atomic setns
to a set of namespaces, i.e. either attaching to all namespaces
succeeds or we fail without having changed anything.
This is centered around a new internal struct nsset which holds all
information necessary for a task to switch to a new set of namespaces
atomically. Fwiw, with this change a pidfd becomes the only token
needed to interact with a container. I'm expecting this to be
picked-up by util-linux for nsenter rather soon.
Associated with this change is a shiny new test-suite dedicated to
setns() (for pidfds and nsfds alike)"

Pull btrfs updates from David Sterba:
"Highlights:
- speedup dead root detection during orphan cleanup, eg. when there
are many deleted subvolumes waiting to be cleaned, the trees are
now looked up in radix tree instead of a O(N^2) search
- snapshot creation with inherited qgroup will mark the qgroup
inconsistent, requires a rescan
- send will emit file capabilities after chown, this produces a
stream that does not need postprocessing to set the capabilities
again
- direct io ported to iomap infrastructure, cleaned up and simplified
code, notably removing last use of struct buffer_head in btrfs code
Core changes:
- factor out backreference iteration, to be used by ordinary
backreferences and relocation code
- improved global block reserve utilization
* better logic to serialize requests
* increased maximum available for unlink
* improved handling on large pages (64K)
- direct io cleanups and fixes
* simplify layering, where cloned bios were unnecessarily created
for some cases
* error handling fixes (submit, endio)
* remove repair worker thread, used to avoid deadlocks during
repair
- refactored block group reading code, preparatory work for new type
of block group storage that should improve mount time on large
filesystems
Cleanups:
- cleaned up (and slightly sped up) set/get helpers for metadata data
structure members
- root bit REF_COWS got renamed to SHAREABLE to reflect the that the
blocks of the tree get shared either among subvolumes or with the
relocation trees
Fixes:
- when subvolume deletion fails due to ENOSPC, the filesystem is not
turned read-only
- device scan deals with devices from other filesystems that changed
ownership due to overwrite (mkfs)
- fix a race between scrub and block group removal/allocation
- fix long standing bug of a runaway balance operation, printing the
same line to the syslog, caused by a stale status bit on a reloc
tree that prevented progress
- fix corrupt log due to concurrent fsync of inodes with shared
extents
- fix space underflow for NODATACOW and buffered writes when it for
some reason needs to fallback to COW mode"

Pull DAX updates part two from Darrick Wong:
"This time around, we're hoisting the DONTCACHE flag from XFS into the
VFS so that we can make the incore DAX mode changes become effective
sooner.
We can't change the file data access mode on a live inode because we
don't have a safe way to change the file ops pointers. The incore
state change becomes effective at inode loading time, which can happen
if the inode is evicted. Therefore, we're making it so that
filesystems can ask the VFS to evict the inode as soon as the last
holder drops.
The per-fs changes to make this call this will be in subsequent pull
requests from Ted and myself.

Pull DAX updates part one from Darrick Wong:
"After many years of LKML-wrangling about how to enable programs to
query and influence the file data access mode (DAX) when a filesystem
resides on storage devices such as persistent memory, Ira Weiny has
emerged with a proposed set of standard behaviors that has not been
shot down by anyone! We're more or less standardizing on the current
XFS behavior and adapting ext4 to do the same.
This is the first of a handful pull requests that will make ext4 and
XFS present a consistent interface for user programs that care about
DAX. We add a statx attribute that programs can check to see if DAX is
enabled on a particular file. Then, we update the DAX documentation to
spell out the user-visible behaviors that filesystems will guarantee
(until the next storage industry shakeup). The on-disk inode flag has
been in XFS for a few years now.
Summary:
- Clean up io_is_direct.
- Add a new statx flag to indicate when file data access is being
done via DAX (as opposed to the page cache).
- Update the documentation for how system administrators and
application programmers can take advantage of the (still

New code for 5.8:
- Various cleanups to remove dead code, unnecessary conditionals,
asserts, etc.
- Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
redundantly.
- Tighten up our dmesg logging to ensure that everything is prefixed
with 'XFS' for easier grepping.
- Kill a bunch of typedefs.
- Refactor the deferred ops code to reduce indirect function calls.
- Increase type-safety with the deferred ops code.
- Make the DAX mount options a tri-state.
- Fix some error handling problems in the inode flush code and clean up
other inode flush warts.
- Refactor log recovery so that each log item recovery functions now live
with the other log item processing code.
- Fix some SPDX forms.
- Fix quota counter corruption if the fs crashes after running
quotacheck but before any dquots get logged.
- Don't fail metadata verification on zero-entry attr leaf blocks, since
they're just part of the disk format now due to a historic lack of log
atomicity.
- Don't allow SWAPEXT between files with different [ugp]id when quotas
are enabled.
- Refactor inode fork reading and verification to run directly from the
inode-from-disk function. This means that we now actually guarantee
that _iget'ted inodes are totally verified and ready to go.
- Move the incore inode fork format and extent counts to the ifork
structure.
- Scalability improvements by reducing cacheline pingponging in
struct xfs_mount.
- More scalability improvements by removing m_active_trans from the
hot path.
- Fix inode counter update sanity checking to run /only/ on debug
kernels.
- Fix longstanding inconsistency in what error code we return when a
program hits project quota limits (ENOSPC).
- Fix group quota returning the wrong error code when a program hits
group quota limits.
- Fix per-type quota limits and grace periods for group and project
quotas so that they actually work.
- Allow extension of individual grace periods.
- Refactor the non-reclaim inode radix tree walking code to remove a
bunch of stupid little functions and straighten out the
inconsistent naming schemes.
- Fix a bug in speculative preallocation where we measured a new
allocation based on the last extent mapping in the file instead of
looking farther for the last contiguous space allocation.
- Force delalloc writes to unwritten extents. This closes a

Merge tag 'xfs-5.8-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"Most of the changes this cycle are refactoring of existing code in
preparation for things landing in the future.
We also fixed various problems and deficiencies in the quota
implementation, and (I hope) the last of the stale read vectors by
forcing write allocations to go through the unwritten state until the
write completes.
Summary:
- Various cleanups to remove dead code, unnecessary conditionals,
asserts, etc.
- Fix a linker warning caused by xfs stuffing '-g' into CFLAGS
redundantly.
- Tighten up our dmesg logging to ensure that everything is prefixed
with 'XFS' for easier grepping.
- Kill a bunch of typedefs.
- Refactor the deferred ops code to reduce indirect function calls.
- Increase type-safety with the deferred ops code.
- Make the DAX mount options a tri-state.
- Fix some error handling problems in the inode flush code and clean
up other inode flush warts.
- Refactor log recovery so that each log item recovery functions now
live with the other log item processing code.
- Fix some SPDX forms.
- Fix quota counter corruption if the fs crashes after running
quotacheck but before any dquots get logged.
- Don't fail metadata verification on zero-entry attr leaf blocks,
since they're just part of the disk format now due to a historic
lack of log atomicity.
- Don't allow SWAPEXT between files with different [ugp]id when
quotas are enabled.
- Refactor inode fork reading and verification to run directly from
the inode-from-disk function. This means that we now actually
guarantee that _iget'ted inodes are totally verified and ready to
go.
- Move the incore inode fork format and extent counts to the ifork
structure.
- Scalability improvements by reducing cacheline pingponging in
struct xfs_mount.
- More scalability improvements by removing m_active_trans from the
hot path.
- Fix inode counter update sanity checking to run /only/ on debug
kernels.
- Fix longstanding inconsistency in what error code we return when a
program hits project quota limits (ENOSPC).
- Fix group quota returning the wrong error code when a program hits
group quota limits.
- Fix per-type quota limits and grace periods for group and project
quotas so that they actually work.
- Allow extension of individual grace periods.
- Refactor the non-reclaim inode radix tree walking code to remove a
bunch of stupid little functions and straighten out the
inconsistent naming schemes.
- Fix a bug in speculative preallocation where we measured a new
allocation based on the last extent mapping in the file instead of
looking farther for the last contiguous space allocation.
- Force delalloc writes to unwritten extents. This closes a stale
disk contents exposure vector if the system goes down before the
write completes.
- More lockdep whackamole"

platform code create a suitable device object for it and add
platform dependencies to it (Mian Yousaf Kaukab, Geert
Uytterhoeven).
* Fix wrong compatible binding in the qcom driver (Ansuel Smith).
* Build the omap driver by default for ARCH_OMAP2PLUS (Anders
Roxell).

- Update devfreq core and drivers:
* Replace strncpy() with strscpy() in the devfreq core and use
lockdep asserts instead of manual checks for a locked mutex in
it (Dmitry Osipenko, Krzysztof Kozlowski).
* Add a generic imx bus scaling driver and make it register an
interconnect device (Leonard Crestez, Gustavo A. R. Silva).
* Make the cpufreq notifier in the tegra30 driver take boosting

/proc/PID/smaps: Add PMD migration entry parsing
Now, when reading /proc/PID/smaps, the PMD migration entry in page table is simply ignored. To improve the accuracy of /proc/PID/smaps, its parsing and processing is added. To test the patch, we run pmbench to eat 400 MB memory in background, then run /usr/bin/migratepages and `cat /proc/PID/smaps` every second. The issue as follows can be reproduced within 60 seconds. Before the patch, for the fully populated 400 MB anonymous VMA, some THP pages under migration may be lost as below. 7f3f6a7e5000-7f3f837e5000 rw-p 00000000 00:00 0 Size: 409600 kB KernelPageSize: 4 kB MMUPageSize: 4 kB Rss: 407552 kB Pss: 407552 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 407552 kB Referenced: 301056 kB Anonymous: 407552 kB LazyFree: 0 kB AnonHugePages: 405504 kB ShmemPmdMapped: 0 kB FilePmdMapped: 0 kB Shared_Hugetlb: 0 kB Private_Hugetlb: 0 kB Swap: 0 kB SwapPss: 0 kB Locked: 0 kB THPeligible: 1 VmFlags: rd wr mr mw me ac After the patch, it will be always, 7f3f6a7e5000-7f3f837e5000 rw-p 00000000 00:00 0 Size: 409600 kB KernelPageSize: 4 kB MMUPageSize: 4 kB Rss: 409600 kB Pss: 409600 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 409600 kB Referenced: 294912 kB Anonymous: 409600 kB LazyFree: 0 kB AnonHugePages: 407552 kB ShmemPmdMapped: 0 kB FilePmdMapped: 0 kB Shared_Hugetlb: 0 kB Private_Hugetlb: 0 kB Swap: 0 kB SwapPss: 0 kB Locked: 0 kB THPeligible: 1 VmFlags: rd wr mr mw me ac Signed-off-by: "Huang, Ying" <ying.huang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: Zi Yan <ziy@nvidia.com> Acked-by: Michal Hocko <mhocko@suse.com> Acked-by: Kirill A.

mm/writeback: discard NR_UNSTABLE_NFS, use NR_WRITEBACK instead
After an NFS page has been written it is considered "unstable" until a
COMMIT request succeeds. If the COMMIT fails, the page will be
re-written.
These "unstable" pages are currently accounted as "reclaimable", either
in WB_RECLAIMABLE, or in NR_UNSTABLE_NFS which is included in a
'reclaimable' count. This might have made sense when sending the COMMIT
required a separate action by the VFS/MM (e.g. releasepage() used to
send a COMMIT). However now that all writes generated by ->writepages()
will automatically be followed by a COMMIT (since commit

mm/writeback: replace PF_LESS_THROTTLE with PF_LOCAL_THROTTLE
PF_LESS_THROTTLE exists for loop-back nfsd (and a similar need in the loop block driver and callers of prctl(PR_SET_IO_FLUSHER)), where a daemon needs to write to one bdi (the final bdi) in order to free up writes queued to another bdi (the client bdi). The daemon sets PF_LESS_THROTTLE and gets a larger allowance of dirty pages, so that it can still dirty pages after other processses have been throttled. The purpose of this is to avoid deadlock that happen when the PF_LESS_THROTTLE process must write for any dirty pages to be freed, but it is being thottled and cannot write. This approach was designed when all threads were blocked equally, independently on which device they were writing to, or how fast it was. Since that time the writeback algorithm has changed substantially with different threads getting different allowances based on non-trivial heuristics. This means the simple "add 25%" heuristic is no longer reliable. The important issue is not that the daemon needs a *larger* dirty page allowance, but that it needs a *private* dirty page allowance, so that dirty pages for the "client" bdi that it is helping to clear (the bdi for an NFS filesystem or loop block device etc) do not affect the throttling of the daemon writing to the "final" bdi. This patch changes the heuristic so that the task is not throttled when the bdi it is writing to has a dirty page count below below (or equal to) the free-run threshold for that bdi. This ensures it will always be able to have some pages in flight, and so will not deadlock. In a steady-state, it is expected that PF_LOCAL_THROTTLE tasks might still be throttled by global threshold, but that is acceptable as it is only the deadlock state that is interesting for this flag. This approach of "only throttle when target bdi is busy" is consistent with the other use of PF_LESS_THROTTLE in current_may_throttle(), were it causes attention to be focussed only on the target bdi. So this patch - renames PF_LESS_THROTTLE to PF_LOCAL_THROTTLE, - removes the 25% bonus that that flag gives, and - If PF_LOCAL_THROTTLE is set, don't delay at all unless the global and the local free-run thresholds are exceeded. Note that previously realtime threads were treated the same as PF_LESS_THROTTLE threads. This patch does *not* change the behvaiour for real-time threads, so it is now different from the behaviour of nfsd and loop tasks. I don't know what is wanted for realtime.
