perf record: Fix way of handling non-perf-event pollfds
perf record __cmd_record() does not poll evlist pollfds. Instead it polls
thread_data[0].pollfd. That happens whether or not threads are being used.
perf record duplicates evlist mmap pollfds as needed for separate threads.
The non-perf-event represented by evlist->ctl_fd has to handled separately,
which is done explicitly, duplicating it into the thread_data[0] pollfds.
That approach neglects any other non-perf-event file descriptors. Currently
there is also done_fd which needs the same handling.
Add a new generalized approach.
Add fdarray_flag__non_perf_event to identify the file descriptors that
need the special handling. For those cases, also keep a mapping of the
evlist pollfd index and thread pollfd index, so that the evlist revents
can be updated.
Although this patch adds the new handling, it does not take it into use.
There is no functional change, but it is the precursor to a fix, so is
marked as a fix.

perf hashmap: Tidy hashmap dependency
When libbpf is present the build uses definitions in libbpf hashmap.c, however, libbpf's hashmap.h wasn't being used. Switch to using the correct hashmap.h dependent on the define HAVE_LIBBPF_SUPPORT.

tools build: Display logical OR of a feature flavors
Sometimes, features are simply different flavors of another feature, to properly detect the exact dependencies needed by different Linux distributions. For example, libbfd has three flavors: libbfd if the distro does not require any additional dependency; libbfd-liberty if it requires libiberty; libbfd-liberty-z if it requires libiberty and libz. It might not be clear to the user whether a feature has been successfully detected or not, given that some of its flavors will be set to OFF, others to ON. Instead, display only the feature main flavor if not in verbose mode (VF != 1), and set it to ON if at least one of its flavors has been successfully detected (logical OR), OFF otherwise. Omit the other flavors. Accomplish that by declaring a FEATURE_GROUP_MEMBERS-<feature main flavor> variable, with the list of the other flavors as variable value. For now, do it just for libbfd. In verbose mode, of if no group is defined for a feature, show the feature detection result as before.

tools build: Fix feature detection output due to eval expansion
As the first eval expansion is used only to generate Makefile statements,
messages should not be displayed at this stage, as for example conditional
expressions are not evaluated.
It can be seen for example in the output of feature detection for bpftool,
where the number of detected features does not change, despite turning on
the verbose mode (VF = 1) and there are additional features to display.
Fix this issue by escaping the $ before $(info) statements, to ensure that
messages are printed only when the function containing them is actually
executed, and not when it is expanded.
In addition, move the $(info) statement out of feature_print_status, due to
the fact that is called both inside and outside an eval context, and place
it to the caller so that the $ can be escaped when necessary. For symmetry,
move the $(info) statement also out of feature_print_text, and place it to
the caller.
Force the TMP variable evaluation in verbose mode, to display the features
in FEATURE_TESTS that are not in FEATURE_DISPLAY.
Reorder perf feature detection messages (first non-verbose, then verbose
ones) by moving the call to feature_display_entries earlier, before the VF
environment variable check.
Also, remove the newline from that function, as perf might display
additional messages. Move the newline to perf Makefile, and display another
one if displaying the detection result is not deferred as in the case of
bpftool.

perf inject: Add a command line option to specify build ids.
This commit adds the option --known-build-ids to perf inject.
It allows the user to explicitly specify the build id for a given
path, instead of retrieving it from the current system. This is
useful in cases where a perf.data file is processed on a different
system from where it was collected, or if some of the binaries are
no longer available.
The build ids and paths are specified in pairs in the command line.
Using the file:// specifier, build ids can be loaded from a file
directly generated by perf buildid-list. This is convenient to copy
build ids from one perf.data file to another.
** Example: In this example we use perf record to create two
perf.data files, one with build ids and another without, and use
perf buildid-list and perf inject to copy the build ids from the
first file to the second.
$ perf record ls /tmp
$ perf record --no-buildid -o perf.data.no-buildid ls /tmp
$ perf buildid-list > build-ids.txt
$ perf inject -b --known-build-ids='file://build-ids.txt' \
-i perf.data.no-buildid -o perf.data.buildid

STATX_DIOALIGN for 6.1
Make statx() support reporting direct I/O (DIO) alignment information. This provides a generic interface for userspace programs to determine whether a file supports DIO, and if so with what alignment restrictions. Specifically, STATX_DIOALIGN works on block devices, and on regular files when their containing filesystem has implemented support. An interface like this has been requested for years, since the conditions for when DIO is supported in Linux have gotten increasingly complex over time. Today, DIO support and alignment requirements can be affected by various filesystem features such as multi-device support, data journalling, inline data, encryption, verity, compression, checkpoint disabling, log-structured mode, etc. Further complicating things, Linux v6.0 relaxed the traditional rule of DIO needing to be aligned to the block device's logical block size; now user buffers (but not file offsets) only need to be aligned to the DMA alignment. The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was discarded in favor of creating a clean new interface with statx().

fscrypt updates for 6.1
This release contains some implementation changes, but no new features:
- Rework the implementation of the fscrypt filesystem-level keyring to
not be as tightly coupled to the keyrings subsystem. This resolves
several issues.
- Eliminate most direct uses of struct request_queue from fs/crypto/,
since struct request_queue is considered to be a block layer
implementation detail.
- Stop using the PG_error flag to track decryption failures. This is a
prerequisite for freeing up PG_error for other uses.

NFSD 6.1 Release Notes
This release is mostly bug fixes, clean-ups, and optimizations. One notable set of fixes addresses a subtle buffer overflow issue that occurs if a small RPC Call message arrives in an oversized RPC record. This is only possible on a framed RPC transport such as TCP. Because NFSD shares the receive and send buffers in one set of pages, an oversized RPC record steals pages from the send buffer that will be used to construct the RPC Reply message. NFSD must not assume that a full-sized buffer is always available to it; otherwise, it will walk off the end of the send buffer while constructing its reply. In this release, we also introduce the ability for the server to wait a moment for clients to return delegations before it responds with NFS4ERR_DELAY. This saves a retransmit and a network round- trip when a delegation recall is needed. This work will be built upon in future releases. The NFS server adds another shrinker to its collection. Because courtesy clients can linger for quite some time, they might be freeable when the server host comes under memory pressure. A new shrinker has been added that releases courtesy client resources during low memory scenarios. Lastly, of note: the maximum number of operations per NFSv4 COMPOUND that NFSD can handle is increased from 16 to 50. There are NFSv4 client implementations that need more than 16 to successfully perform a mount operation that uses a pathname with many components. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmM66P4ACgkQM2qzM29m f5fhMg//afS2mp4fgPz4MjoFIqD/Icep8qFEPA8Gy6I1dDGRxd9wNgjoN4JALFdr NKX1oRVISBvDrOG/C84GbYnXEDlzY8q1HmyPoJA8VAR57hnJXfPZN6CBN//Bx4mU nISPJeNGY9SMNVhS8916V/yzd41uWDQuD+H+i5mluBTJHONgSzwzc80sQ+eq+yZQ PV6mlJN6hcm14LCaDOTXF7oY2Wm6dQc2rV87YChJWnc+vdXKnme/LWTMY1ABkePD g88mSL6w3YDKEuKciWda5/QU1ETp/Q7XTjFGDKEQSnnNsvCLmUKogJTKVa2QqyLY P1qlrj6XwukqAe414W4amlLL3q4NUFmJZPNWDxdf+qtTrQrBBEFrsKy/bSt27XoD cTvBWcorMG2riSlYPViVeh8RpyC6qwhttPbvGAmflVF2KEyXpfgc5Pnn0/Xm1Ac9 XKzaCTJlUyRb/2wdqVtQbIpyh3sbhzp8zhv7sWKXgQOEXxKOO3ZAIrQXeL6oFN/b HlXDty7wKhFRj8IbkZfQ9SvN1saTONwB3clYHbCXTetkw/nnrUgLYcu8NIDBK9ou wkBcz1++XgVTqjRFwUwagb62cPJnRM6UiROYCVbQp7qcUe4/U+WP9t6dnZlnGZVZ dtipKlH/LTGKW+d7ysZOqb4hsRza5Kaduz5a7lML7UIGQXmxjM0= =hE6t -----END PGP SIGNATURE----- Merge tag 'nfsd-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This release is mostly bug fixes, clean-ups, and optimizations.

"In this cycle, for container use cases, fscache-based shared domain is
introduced [1] so that data blobs in the same domain will be storage
deduplicated and it will also be used for page cache sharing later.
Also, a special packed inode is now introduced to record inode
fragments which keep the tail part of files by Yue Hu [2]. You can
keep arbitary length or (at will) the whole file as a fragment and
then fragments can be optionally compressed in the packed inode
together and even deduplicated for smaller image sizes.
In addition to that, global compressed data deduplication by sharing
partial-referenced pclusters is also supported in this cycle.

Pull fatfs vfsuid conversion from Christian Brauner:
"Last cycle we introduced the new vfs{g,u}id_t types that we had agreed
on. The most important parts of the vfs have been converted but there
are a few more places we need to switch before we can remove the old
helpers completely.
This cycle we converted all filesystems that called idmapped mount
helpers directly. The affected filesystems are f2fs, fat, fuse, ksmbd,
overlayfs, and xfs. We've sent patches for all of them. Looking at
-next f2fs, ksmbd, overlayfs, and xfs have all picked up these patches
and they should land in mainline during the v6.1 merge window.
So all filesystems that have a separate tree should send the vfsuid
conversion themselves. Onle the fat conversion is going through this
generic fs trees because there is no fat tree.
In order to change time settings on an inode fat checks that the
caller either is the owner of the inode or the inode's group is in the
caller's group list. If fat is on an idmapped mount we compare whether
the inode mapped into the mount is equivalent to the caller's fsuid.
If it isn't we compare whether the inode's group mapped into the mount
is in the caller's group list.
We now use the new vfsuid based helpers for that"

Pull vfs acl updates from Christian Brauner:
"These are general fixes and preparatory changes related to the ongoing
posix acl rework. The actual rework where we build a type safe posix
acl api wasn't ready for this merge window but we're hopeful for the
next merge window.
General fixes:
- Some filesystems like 9p and cifs have to implement custom posix
acl handlers because they require access to the dentry in order to
set and get posix acls while the set and get inode operations
currently don't. But the ntfs3 filesystem has no such requirement
and thus implemented custom posix acl xattr handlers when it really
didn't have to. So this pr contains patch that just implements set
and get inode operations for ntfs3 and switches it to rely on the
generic posix acl xattr handlers. (We would've appreciated reviews
from the ntfs3 maintainers but we didn't get any. But hey, if we
really broke it we'll fix it. But fstests for ntfs3 said it's
fine.)
- The posix_acl_fix_xattr_common() helper has been adapted so it can
be used by a few more callers and avoiding open-coding the same
checks over and over.
Other than the two general fixes this series introduces a new helper
vfs_set_acl_prepare(). The reason for this helper is so that we can
mitigate one of the source that change {g,u}id values directly in the
uapi struct. With the vfs_set_acl_prepare() helper we can move the
idmapped mount fixup into the generic posix acl set handler.
The advantage of this is that it allows us to remove the
posix_acl_setxattr_idmapped_mnt() helper which so far we had to call
in vfs_setxattr() to account for idmapped mounts. While semantically
correct the problem with this approach was that we had to keep the
value parameter of the generic vfs_setxattr() call as non-const. This
is rectified in this series.
Ultimately, we will get rid of all the extreme kludges and type
unsafety once we have merged the posix api - hopefully during the next
merge window - built solely around get and set inode operations. Which
incidentally will also improve handling of posix acls in security and
especially in integrity modesl. While this will come with temporarily
having two inode operation for posix acls that is nothing compared to
the problems we have right now and so well worth it. We'll end up with
something that we can actually reason about instead of needing to
write novels to explain what's going on"

Merge tag 'lsm-pr-20221003' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
Pull LSM updates from Paul Moore:
"Seven patches for the LSM layer and we've got a mix of trivial and
significant patches. Highlights below, starting with the smaller bits
first so they don't get lost in the discussion of the larger items:
- Remove some redundant NULL pointer checks in the common LSM audit
code.
- Ratelimit the lockdown LSM's access denial messages.
With this change there is a chance that the last visible lockdown
message on the console is outdated/old, but it does help preserve
the initial series of lockdown denials that started the denial
message flood and my gut feeling is that these might be the more
valuable messages.
- Open userfaultfds as readonly instead of read/write.
While this code obviously lives outside the LSM, it does have a
noticeable impact on the LSMs with Ondrej explaining the situation
in the commit description. It is worth noting that this patch
languished on the VFS list for over a year without any comments
(objections or otherwise) so I took the liberty of pulling it into
the LSM tree after giving fair notice. It has been in linux-next
since the end of August without any noticeable problems.
- Add a LSM hook for user namespace creation, with implementations
for both the BPF LSM and SELinux.
Even though the changes are fairly small, this is the bulk of the
diffstat as we are also including BPF LSM selftests for the new
hook.
It's also the most contentious of the changes in this pull request
with Eric Biederman NACK'ing the LSM hook multiple times during its
development and discussion upstream. While I've never taken NACK's
lightly, I'm sending these patches to you because it is my belief
that they are of good quality, satisfy a long-standing need of
users and distros, and are in keeping with the existing nature of
the LSM layer and the Linux Kernel as a whole.
The patches in implement a LSM hook for user namespace creation
that allows for a granular approach, configurable at runtime, which
enables both monitoring and control of user namespaces. The general
consensus has been that this is far preferable to the other
solutions that have been adopted downstream including outright
removal from the kernel, disabling via system wide sysctls, or
various other out-of-tree mechanisms that users have been forced to
adopt since we haven't been able to provide them an upstream
solution for their requests. Eric has been steadfast in his
objections to this LSM hook, explaining that any restrictions on
the user namespace could have significant impact on userspace.
While there is the possibility of impacting userspace, it is
important to note that this solution only impacts userspace when it
is requested based on the runtime configuration supplied by the
distro/admin/user. Frederick (the pathset author), the LSM/security
community, and myself have tried to work with Eric during
development of this patchset to find a mutually acceptable
solution, but Eric's approach and unwillingness to engage in a
meaningful way have made this impossible. I have CC'd Eric directly
on this pull request so he has a chance to provide his side of the
story; there have been no objections outside of Eric's"

Pull SELinux updates from Paul Moore:
"Six SELinux patches, all are simple and easily understood, but a list
of the highlights is below:
- Use 'grep -E' instead of 'egrep' in the SELinux policy install
script.
Fun fact, this seems to be GregKH's *second* dedicated SELinux
patch since we transitioned to git (ignoring merges, the SPDX
stuff, and a trivial fs reference removal when lustre was yanked);
the first was back in 2011 when selinuxfs was placed in
/sys/fs/selinux. Oh, the memories ...
- Convert the SELinux policy boolean values to use signed integer
types throughout the SELinux kernel code.
Prior to this we were using a mix of signed and unsigned integers
which was probably okay in this particular case, but it is
definitely not a good idea in general.
- Remove a reference to the SELinux runtime disable functionality in
/etc/selinux/config as we are in the process of deprecating that.
See [1] for more background on this if you missed the previous
notes on the deprecation.

constification"

The most notable new feature here is the addition of the memcpy()
overflow warning (under CONFIG_FORTIFY_SOURCE), which is the next step
on the path to killing the common class of "trivially detectable"
buffer overflow conditions (i.e. on arrays with sizes known at compile
time) that have resulted in many exploitable vulnerabilities over the
years (e.g. BleedingTooth).
This feature is expected to still have some undiscovered false
positives. It's been in -next for a full development cycle and all the
reported false positives have been fixed in their respective trees.
All the known-bad code patterns we could find with Coccinelle are also
either fixed in their respective trees or in flight.

kcfi updates for v6.1-rc1
This replaces the prior support for Clang's standard Control Flow
Integrity (CFI) instrumentation, which has required a lot of special
conditions (e.g. LTO) and work-arounds. The current implementation
("Kernel CFI") is specific to C, directly designed for the Linux kernel,
and takes advantage of architectural features like x86's IBT. This
series retains arm64 support and adds x86 support. Additional "generic"
architectural support is expected soon:
https://github.com/samitolvanen/llvm-project/commits/kcfi_generic
- treewide: Remove old CFI support details
- arm64: Replace Clang CFI support with Clang KCFI support
- x86: Introduce Clang KCFI support

The new implementation ("Kernel CFI") is specific to C, directly
designed for the Linux kernel, and takes advantage of architectural
features like x86's IBT. This series retains arm64 support and adds
x86 support.
GCC support is expected in the future[1], and additional "generic"
architectural support is expected soon[2].
Summary:
- treewide: Remove old CFI support details
- arm64: Replace Clang CFI support with Clang KCFI support
- x86: Introduce Clang KCFI support"

Rust introduction for v6.1-rc1
The initial support of Rust-for-Linux comes in roughly 4 areas: - Kernel internals (kallsyms expansion for Rust symbols, %pA format) - Kbuild infrastructure (Rust build rules and support scripts) - Rust crates and bindings for initial minimum viable build - Rust kernel documentation and samples Rust support has been in linux-next for a year and a half now, and the short log doesn't do justice to the number of people who have contributed both to the Linux kernel side but also to the upstream Rust side to support the kernel's needs.

Thermal control updates for 6.1-rc1
- Rework the device tree initialization, convert the drivers to the
new API and remove the old OF code (Daniel Lezcano).
- Fix return value to -ENODEV when searching for a specific thermal
zone which does not exist (Daniel Lezcano).
- Fix the return value inspection in of_thermal_zone_find() (Dan
Carpenter).
- Fix kernel panic when KASAN is enabled as it detects use after
free when unregistering a thermal zone (Daniel Lezcano).
- Move the set_trip ops inside the therma sysfs code (Daniel Lezcano).
- Remove unnecessary error message as it is already shown in the
underlying function (Jiapeng Chong).
- Rework the monitoring path and move the locks upper in the call
stack to fix some potentials race windows (Daniel Lezcano).
- Fix lockdep_assert() warning introduced by the lock rework (Daniel
Lezcano).
- Do not lock thermal zone mutex in the user space governor (Rafael
Wysocki).
- Revert the Mellanox 'hotter thermal zone' feature because it is
already handled in the thermal framework core code (Daniel Lezcano).
- Increase maximum number of trip points in the thermal core (Sumeet
Pawnikar).
- Replace strlcpy() with unused retval with strscpy() in the core
thermal control code (Wolfram Sang).
- Use module_pci_driver() macro in the int340x processor_thermal
driver (Shang XiaoJing).
- Use get_cpu() instead of smp_processor_id() in the intel_powerclamp
thermal driver to prevent it from crashing and remove unused
accounting for IRQ wakes from it (Srinivas Pandruvada).
- Consolidate priv->data_vault checks in int340x_thermal (Rafael
Wysocki).
- Check the policy first in cpufreq_cooling_register() (Xuewen Yan).
- Drop redundant error message from da9062-thermal (zhaoxiao).
- Drop of_match_ptr() from thermal_mmio (Jean Delvare).

There's not a huge amount of activity in the docs tree this time around,
but a few significant changes even so:
- A complete rewriting of the top-level index.rst file, which mostly
reflects itself in a redone top page in the HTML-rendered docs. The hope
is that the new organization will be a friendlier starting point for
both users and developers.
- Some math-rendering improvements.
- A coding-style.rst update on the use of BUG() and WARN()
- A big maintainer-PHP guide update.
- Some code-of-conduct updates
- More Chinese translation work
Plus the usual pile of typo fixes, corrections, and updates.

This pull request contains the following branches: doc.2022.08.31b: Documentation updates. This is the first in a series from an ongoing review of the RCU documentation. "Why are people thinking -that- about RCU? Oh. Because that is an entirely reasonable interpretation of its documentation." fixes.2022.08.31b: Miscellaneous fixes. kvfree.2022.08.31b: Improved memory allocation and heuristics. nocb.2022.09.01a: Improve rcu_nocbs diagnostic output. poll.2022.08.31b: Add full-sized polled RCU grace period state values. These are the same size as an rcu_head structure, which is double that of the traditional unsigned long state values that may still be obtained from et_state_synchronize_rcu(). The added size avoids missing overlapping grace periods. This benefit is that call_rcu() can be replaced by polling, which can be attractive in situations where RCU-protected data is aged out of memory. Early in the series, the size of this state value is three unsigned longs. Later in the series, the synchronize_rcu() and synchronize_rcu_expedited() fastpaths are reworked to permit the full state to be represented by only two unsigned longs. This reworking slows these two functions down in SMP kernels running either on single-CPU systems or on systems with all but one CPU offlined, but this should not be a significant problem. And if it somehow becomes a problem in some yet-as-unforeseen situations, three-value state values can be provided for only those situations. Finally, a pair of functions named same_state_synchronize_rcu() and same_state_synchronize_rcu_full() allow grace-period state values to be compared for equality. This permits users to maintain lists of data structures having the same state value, removing the need for per-data-structure grace-period state values, thus decreasing memory footprint. poll-srcu.2022.08.31b: Polled SRCU grace-period updates, including adding tests to rcutorture and reducing the incidence of Tiny SRCU grace-period-state counter wrap. tasks.2022.08.31b: Improve Tasks RCU diagnostics and quiescent-state detection. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmM3bxQTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jC0zD/0cPe9Nl3LPKVTqDN8wWG6SUOHcwQrg dLBUo1pbBh3mK3HcHzwl1iIF7gd2nmKN7UT3m+C+qv+N3Q9ej9K+MutGThCiRvNT A56TDYU9I1xfqoQ25E9TL7nqty818rtYYMl36Rw8epcLKHo/It9MFODb5kEBY5ir P5UaIK2D4heHfJL6Di8JDq9vC5a/NlNIIkiIj7lUB+px0FpVW0dUqmnWbIOE74YH OBGJ/Mxn6KDO4WeFO0v0DxVaBTLd+khu6W0JspI0szOO6iyTqiDCGE5EqkEdcs5I Fk9WCifdo9nrQG0LPIuEBv0YnwNfGbe5nYXupAmGFb3tdCbjkM+W0UBUE032nXog 3E6m5FEBD1XGQttScFHm70kYssa+xI7khGb9/ZFoYN/QW28oWqwfnx6+eAZGxPNS AZx6pc2bebg8sOUhkz/Sv+qMH7CQgIgcMR66SKl5SdT1Onaig45sgdUuC23BshgG oEdDxvK7vexFQT6q0oqU8LAO/CVKdyVIswt3pB6CUmn8yNgSo+qDZzlEHt0gPdMY 4Xa1jnNtOHobDnI4g0JMdVqAujByrRq74ZsVW96hdedKrA0r9y462jnVBm9tqW68 lu0Lw9WLif2kw0lMY8Q59zqTL+fB8TdNiZrHoqefwvQ/ZrvinfHGSblcrS8zAhX3 4oVwCUs9pPQRMA== =AZPZ -----END PGP SIGNATURE----- Merge tag 'rcu.2022.09.30a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Documentation updates.
