cifs: Call MID callback before destroying transport
When transport is being destroyed, it's possible that some processes may hold memory registrations that need to be deregistred. Call them first so nobody is using transport resources, and it can be destroyed. Signed-off-by: Long Li <longli@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com> |

cifs: smbd: Retry on memory registration failure
Memory registration failure doesn't mean this I/O has failed, it means the transport is hitting I/O error or needs reconnect. This error is not from the server. Indicate this error to upper layer, and let upper layer decide how to reconnect and proceed with this I/O.

cifs: smbd: Indicate to retry on transport sending failure
Failure to send a packet doesn't mean it's a permanent failure, it can't be returned to user process. This I/O should be retried or failed based on server packet response and transport health. This logic is handled by the upper layer. Give this decision to upper layer. Signed-off-by: Long Li <longli@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com> |

smbd: Make upper layer decide when to destroy the transport
On transport recoonect, upper layer CIFS code destroys the current transport and then recoonect. This code path is not used by SMBD, in that SMBD destroys its transport on RDMA disconnect notification independent of CIFS upper layer behavior. This approach adds some costs to SMBD layer to handle transport shutdown and restart, and to deal with several racing conditions on reconnecting transport. Re-work this code path by introducing a new smbd_destroy. This function is called form upper layer to ask SMBD to destroy the transport. SMBD will no longer need to destroy the transport by itself while worrying about data transfer is in progress. The upper layer guarantees the transport is locked. change log: v2: fix build errors when CONFIG_CIFS_SMB_DIRECT is not configured Signed-off-by: Long Li <longli@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com> |

CIFS: check CIFS_MOUNT_NO_DFS when trying to reuse existing sb
if we mount A then mount A again with nodfs, we shouldn't reuse the superblock. document the purpose of the defines as well. there are most likely more flags that needs to be added to this mask, in fact the logic to find them should be which flag should be *ignored* when trying to reuse an existing sb.

"We've got a reasonably broad set of audit patches for the v5.2 merge
window, the highlights are below:
- The biggest change, and the source of all the arch/* changes, is
the patchset from Dmitry to help enable some of the work he is
doing around PTRACE_GET_SYSCALL_INFO.
To be honest, including this in the audit tree is a bit of a
stretch, but it does help move audit a little further along towards
proper syscall auditing for all arches, and everyone else seemed to
agree that audit was a "good" spot for this to land (or maybe they
just didn't want to merge it? dunno.).
- We can now audit time/NTP adjustments.
- We continue the work to connect associated audit records into a
single event"

Char/Misc patches for 5.2-rc1 - part 2
Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small driver
subsystems" these days. Which is fine with me, if it makes things
easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported
issues.

Char/Misc patches for 5.2-rc1 - part 1
This is the first pull request for the char/misc driver tree for 5.2-rc1 This contains only a small number of bugfixes that would have gone to you for 5.1-rc8 if that had happened, but instead I let them sit in linux-next for an extra week just "to be sure". The "big" patch here is for hyper-v, fixing a bug in their sysfs files that could cause big problems. The others are all small fixes, resolving reported issues that showed up in 5.1-rcs, plus some odd 'static' cleanups for the phy drivers that really should have waited for -rc1.

Staging / IIO driver patches for 5.2-rc1
Here is the big staging and iio driver update for 5.2-rc1.
Lots of tiny fixes all over the staging and IIO driver trees here, along
with some new IIO drivers.
Also we ended up deleting two drivers, making this pull request remove a
few hundred thousand lines of code, always a nice thing to see. Both of
the drivers removed have been replaced with "real" drivers in their
various subsystem directories, and they will be coming to you from those
locations during this merge window.
There are some core vt/selection changes in here, that was due to some
cleanups needed for the speakup fixes. Those have all been acked by the
various subsystem maintainers (i.e. me), so those are ok.
We also added a few new drivers, for some odd hardware, giving new
developers plenty to work on with basic coding style cleanups to come in
the near future.
Other than that, nothing unusual here.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon.

Driver core/kobject patches for 5.2-rc1
Here is the "big" set of driver core patches for 5.2-rc1
There are a number of ACPI patches in here as well, as Rafael said they
should go through this tree due to the driver core changes they
required. They have all been acked by the ACPI developers.
There are also a number of small subsystem-specific changes in here, due
to some changes to the kobject core code. Those too have all been acked
by the various subsystem maintainers.
As for content, it's pretty boring outside of the ACPI changes:
- spdx cleanups
- kobject documentation updates
- default attribute groups for kobjects
- other minor kobject/driver core fixes
All have been in linux-next for a while with no reported issues.

Wimplicit-fallthrough patches for 5.2-rc1
Hi Linus, This is my very first pull-request. I've been working full-time as a kernel developer for more than two years now. During this time I've been fixing bugs reported by Coverity all over the tree and, as part of my work, I'm also contributing to the KSPP. My work in the kernel community has been supervised by Greg KH and Kees Cook. OK. So, after the quick introduction above, please, pull the following patches that mark switch cases where we are expecting to fall through. These patches are part of the ongoing efforts to enable -Wimplicit-fallthrough. They have been ignored for a long time (most of them more than 3 months, even after pinging multiple times), which is the reason why I've created this tree. Most of them have been baking in linux-next for a whole development cycle. And with Stephen Rothwell's help, we've had linux-next nag-emails going out for newly introduced code that triggers -Wimplicit-fallthrough to avoid gaining more of these cases while we work to remove the ones that are already present. I'm happy to let you know that we are getting close to completing this work. Currently, there are only 32 of 2311 of these cases left to be addressed in linux-next. I'm auditing every case; I take a look into the code and analyze it in order to determine if I'm dealing with an actual bug or a false positive, as explained here: https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/ While working on this, I've found and fixed the following missing break/return bugs, some of them introduced more than 5 years ago: |

Linus originally suggested to implement this as a new flag to clone() instead of making it a separate system call. After a thorough review from Oleg CLONE_PIDFD returns pidfds in the parent_tidptr argument. This means we can give back the associated pid and the pidfd at the same time. Access to process metadata information thus becomes rather trivial. As has been agreed, CLONE_PIDFD creates file descriptors based on anonymous inodes similar to the new mount api. They are made unconditional by this patchset as they are now needed by core kernel code (vfs, pidfd) even more than they already were before (timerfd, signalfd, io_uring, epoll etc.). The core patchset is rather small. The bulky looking changelist is caused by David's very simple changes to Kconfig to make anon inodes unconditional. A pidfd comes with additional information in fdinfo if the kernel supports procfs. The fdinfo file contains the pid of the process in the callers pid namespace in the same format as the procfs status file, i.e. "Pid:\t%d". To remove worries about missing metadata access this patchset comes with a sample/test program that illustrates how a combination of CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free access to process metadata through /proc/<pid>. Further work based on this patchset has been done by Joel. His work makes pidfds pollable. It finished too late for this merge window. I would prefer to have it sitting in linux-next for a while and send it for inclusion during the 5.3 merge window" * tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: samples: show race-free pidfd metadata access signal: support CLONE_PIDFD with pidfd_send_signal clone: add CLONE_PIDFD Make anon_inodes unconditional |

Pull xfs updates from Darrick Wong:
"Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
ability to report metadata health status to userspace after online
fsck checks the filesystem. The online metadata checking code is (I
really hope) feature complete with the addition of checks for the
global fs counters, though it'll remain EXPERIMENTAL for now.
There are also fixes for thundering herds of writeback completions and
some other deadlocks, fixes for theoretical integer overflow attacks
on space accounting, and removal of the long-defunct 'mntpt' option
which was deprecated in the mid-2000s and (it turns out) totally
broken since 2011 (and nobody complained...).
Summary:
- Fix some more buffer deadlocks when performing an unmount after a
hard shutdown.
- Fix some minor space accounting issues.
- Fix some use after free problems.
- Make the (undocumented) FITRIM behavior consistent with other
filesystems.
- Embiggen the xfs geometry ioctl's data structure.
- Introduce a new AG geometry ioctl.
- Introduce a new online health reporting infrastructure and ioctl
for userspace to query a filesystem's health status.
- Enhance online scrub and repair to update the health reports.
- Reduce thundering herd problems when writeback io completes.
- Fix some transaction reservation type errors.
- Fix integer overflow problems with delayed alloc reservation

Pull btrfs updates from David Sterba:
"This time the majority of changes are cleanups, though there's still a
number of changes of user interest.
User visible changes:
- better read time and write checks to catch errors early and before
writing data to disk (to catch potential memory corruption on data
that get checksummed)
- qgroups + metadata relocation: last speed up patch int the series
to address the slowness, there should be no overhead comparing
balance with and without qgroups
- FIEMAP ioctl does not start a transaction unnecessarily, this can
result in a speed up and less blocking due to IO
- LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this
can speed up the mentioned ioctl and scrub as well
- fsync on files with many (but not too many) hardlinks is faster,
finer decision if the links should be fsynced individually or
completely
- send tries harder to find ranges to clone
- trim/discard will skip unallocated chunks that haven't been touched
since the last mount
Fixes:
- send flushes delayed allocation before start, otherwise it could
miss some changes in case of a very recent rw->ro switch of a
subvolume
- fix fallocate with qgroups that could lead to space accounting
underflow, reported as a warning
- trim/discard ioctl honours the requested range
- starting send and dedupe on a subvolume at the same time will let
only one of them succeed, this is to prevent changes that send
could miss due to dedupe; both operations are restartable
Core changes:
- more tree-checker validations, errors reported by fuzzing tools:
- device item
- inode item
- block group profiles
- tracepoints for extent buffer locking
- async cow preallocates memory to avoid errors happening too deep in
the call chain
- metadata reservations for delalloc reworked to better adapt in
many-writers/low-space scenarios
- improved space flushing logic for intense DIO vs buffered workloads
- lots of cleanups
- removed unused struct members
- redundant argument removal
- properties and xattrs
- extent buffer locking
- selftests
- use common file type conversions
- many-argument functions reduction"

One small feature was added this release but the bulk of the diffstat
and the changelog comes from the fact that several older drivers got
some fairly hefty reworks and a couple of new drivers were added:
- Support for detailed control of timing around chip selects from
Sowjanya Komatineni.
- A big set of fixes and imrovements for the Tegra114 driver from
Sowjanya Komatineni.
- A big simplification of the GPIO driver from Andrey Smirnov.

io_uring: use cpu_online() to check p->sq_thread_cpu instead of cpu_possible()
This issue is found by running liburing/test/io_uring_setup test. When test run, the testcase "attempt to bind to invalid cpu" would not pass with messages like: io_uring_setup(1, 0xbfc2f7c8), \ flags: IORING_SETUP_SQPOLL|IORING_SETUP_SQ_AFF, \ resv: 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000, \ sq_thread_cpu: 2 expected -1, got 3 FAIL On my system, there is: CPU(s) possible : 0-3 CPU(s) online : 0-1 CPU(s) offline : 2-3 CPU(s) present : 0-1 The sq_thread_cpu 2 is offline on my system, so the bind should fail. But cpu_possible() will pass the check. We shouldn't be able to bind to an offline cpu. Use cpu_online() to do the check. After the change, the testcase run as expected: EINVAL will be returned for cpu offlined.

regulator: Updates for v5.2
In terms of big picture changes this has been an extremely quiet release
however there's a lot of changes and a fairly big diffstat thanks to a
bunch of small fixes, mainly coming from Axel Lin. Thanks to his work
this release removes code overall even though we've added a new (albiet
fairly small) driver.
Notable things:
- A fix for a long standing issue with locking on error interrupts from
Steve Twiss.
- A new driver for ST Microelectonics STM32 PWR.

samples: show race-free pidfd metadata access
This is a sample program showing userspace how to get race-free access
to process metadata from a pidfd. It is rather easy to do and userspace
can actually simply reuse code that currently parses a process's status
file in procfs.
The program can easily be extended into a generic helper suitable for
inclusion in a libc to make it even easier for userspace to gain metadata
access.
Since this came up in a discussion because this API is going to be used
in various service managers: A lot of programs will have a whitelist
seccomp filter that returns <some-errno> for all new syscalls. This
means that programs might get confused if CLONE_PIDFD works but the
later pidfd_send_signal() syscall doesn't. Hence, here's a ahead of
time check that pidfd_send_signal() is supported:
bool pidfd_send_signal_supported()
{
int procfd = open("/proc/self", O_DIRECTORY | O_RDONLY | O_CLOEXEC);
if (procfd < 0)
return false;
/*
* A process is always allowed to signal itself so
* pidfd_send_signal() should never fail this test. If it does
* it must mean it is not available, blocked by an LSM, seccomp,
* or other.
*/
return pidfd_send_signal(procfd, 0, NULL, 0) == 0;
}

signal: support CLONE_PIDFD with pidfd_send_signal
Let pidfd_send_signal() use pidfds retrieved via CLONE_PIDFD. With this patch pidfd_send_signal() becomes independent of procfs. This fullfils the request made when we merged the pidfd_send_signal() patchset. The pidfd_send_signal() syscall is now always available allowing for it to be used by users without procfs mounted or even users without procfs support compiled into the kernel.
