Pull idmapped mounts from Christian Brauner:
"This introduces idmapped mounts which has been in the making for some
time. Simply put, different mounts can expose the same file or
directory with different ownership. This initial implementation comes
with ports for fat, ext4 and with Christoph's port for xfs with more
filesystems being actively worked on by independent people and
maintainers.
Idmapping mounts handle a wide range of long standing use-cases. Here
are just a few:
- Idmapped mounts make it possible to easily share files between
multiple users or multiple machines especially in complex
scenarios. For example, idmapped mounts will be used in the
implementation of portable home directories in
systemd-homed.service(8) where they allow users to move their home
directory to an external storage device and use it on multiple
computers where they are assigned different uids and gids. This
effectively makes it possible to assign random uids and gids at
login time.
- It is possible to share files from the host with unprivileged
containers without having to change ownership permanently through
chown(2).
- It is possible to idmap a container's rootfs and without having to
mangle every file. For example, Chromebooks use it to share the
user's Download folder with their unprivileged containers in their
Linux subsystem.
- It is possible to share files between containers with
non-overlapping idmappings.
- Filesystem that lack a proper concept of ownership such as fat can
use idmapped mounts to implement discretionary access (DAC)
permission checking.
- They allow users to efficiently changing ownership on a per-mount
basis without having to (recursively) chown(2) all files. In
contrast to chown (2) changing ownership of large sets of files is
instantenous with idmapped mounts. This is especially useful when
ownership of a whole root filesystem of a virtual machine or
container is changed. With idmapped mounts a single syscall
mount_setattr syscall will be sufficient to change the ownership of
all files.
- Idmapped mounts always take the current ownership into account as
idmappings specify what a given uid or gid is supposed to be mapped
to. This contrasts with the chown(2) syscall which cannot by itself
take the current ownership of the files it changes into account. It
simply changes the ownership to the specified uid and gid. This is
especially problematic when recursively chown(2)ing a large set of
files which is commong with the aforementioned portable home
directory and container and vm scenario.
- Idmapped mounts allow to change ownership locally, restricting it
to specific mounts, and temporarily as the ownership changes only
apply as long as the mount exists.
Several userspace projects have either already put up patches and
pull-requests for this feature or will do so should you decide to pull
this:
- systemd: In a wide variety of scenarios but especially right away
in their implementation of portable home directories.
https://systemd.io/HOME_DIRECTORY/
- container runtimes: containerd, runC, LXD:To share data between
host and unprivileged containers, unprivileged and privileged
containers, etc. The pull request for idmapped mounts support in
containerd, the default Kubernetes runtime is already up for quite
a while now: https://github.com/containerd/containerd/pull/4734
- The virtio-fs developers and several users have expressed interest
in using this feature with virtual machines once virtio-fs is
ported.
- ChromeOS: Sharing host-directories with unprivileged containers.
I've tightly synced with all those projects and all of those listed
here have also expressed their need/desire for this feature on the
mailing list. For more info on how people use this there's a bunch of
talks about this too. Here's just two recent ones:
https://www.cncf.io/wp-content/uploads/2020/12/Rootless-Containers-in-Gitpod.pdf
https://fosdem.org/2021/schedule/event/containers_idmap/
This comes with an extensive xfstests suite covering both ext4 and
xfs:
https://git.kernel.org/brauner/xfstests-dev/h/idmapped_mounts
It covers truncation, creation, opening, xattrs, vfscaps, setid
execution, setgid inheritance and more both with idmapped and
non-idmapped mounts. It already helped to discover an unrelated xfs
setgid inheritance bug which has since been fixed in mainline. It will
be sent for inclusion with the xfstests project should you decide to
merge this.
In order to support per-mount idmappings vfsmounts are marked with
user namespaces. The idmapping of the user namespace will be used to
map the ids of vfs objects when they are accessed through that mount.
By default all vfsmounts are marked with the initial user namespace.
The initial user namespace is used to indicate that a mount is not
idmapped. All operations behave as before and this is verified in the
testsuite.
Based on prior discussions we want to attach the whole user namespace
and not just a dedicated idmapping struct. This allows us to reuse all
the helpers that already exist for dealing with idmappings instead of
introducing a whole new range of helpers. In addition, if we decide in
the future that we are confident enough to enable unprivileged users
to setup idmapped mounts the permission checking can take into account
whether the caller is privileged in the user namespace the mount is
currently marked with.
The user namespace the mount will be marked with can be specified by
passing a file descriptor refering to the user namespace as an
argument to the new mount_setattr() syscall together with the new
MOUNT_ATTR_IDMAP flag. The system call follows the openat2() pattern
of extensibility.
The following conditions must be met in order to create an idmapped
mount:
- The caller must currently have the CAP_SYS_ADMIN capability in the
user namespace the underlying filesystem has been mounted in.
- The underlying filesystem must support idmapped mounts.
- The mount must not already be idmapped. This also implies that the
idmapping of a mount cannot be altered once it has been idmapped.
- The mount must be a detached/anonymous mount, i.e. it must have
been created by calling open_tree() with the OPEN_TREE_CLONE flag
and it must not already have been visible in the filesystem.
The last two points guarantee easier semantics for userspace and the
kernel and make the implementation significantly simpler.
By default vfsmounts are marked with the initial user namespace and no
behavioral or performance changes are observed.
The manpage with a detailed description can be found here:
https://git.kernel.org/brauner/man-pages/c/1d7b902e2875a1ff342e036a9f866a995640aea8
In order to support idmapped mounts, filesystems need to be changed
and mark themselves with the FS_ALLOW_IDMAP flag in fs_flags. The
patches to convert individual filesystem are not very large or
complicated overall as can be seen from the included fat, ext4, and
xfs ports. Patches for other filesystems are actively worked on and
will be sent out separately. The xfstestsuite can be used to verify
that port has been done correctly.
The mount_setattr() syscall is motivated independent of the idmapped
mounts patches and it's been around since July 2019. One of the most
valuable features of the new mount api is the ability to perform
mounts based on file descriptors only.
Together with the lookup restrictions available in the openat2()
RESOLVE_* flag namespace which we added in v5.6 this is the first time
we are close to hardened and race-free (e.g. symlinks) mounting and
path resolution.
While userspace has started porting to the new mount api to mount
proper filesystems and create new bind-mounts it is currently not
possible to change mount options of an already existing bind mount in
the new mount api since the mount_setattr() syscall is missing.
With the addition of the mount_setattr() syscall we remove this last
restriction and userspace can now fully port to the new mount api,
covering every use-case the old mount api could. We also add the
crucial ability to recursively change mount options for a whole mount
tree, both removing and adding mount options at the same time. This
syscall has been requested multiple times by various people and
projects.
There is a simple tool available at
https://github.com/brauner/mount-idmapped
that allows to create idmapped mounts so people can play with this
patch series. I'll add support for the regular mount binary should you
decide to pull this in the following weeks:
Here's an example to a simple idmapped mount of another user's home

The removal of EXPORT_UNUSED_SYMBOL() in commit 367948220fce looks like
(and was sold as) a no-op, but it actually had a rather serious and
subtle side effect: the UNUSED_SYMBOLS option not only enabled the
removed (unused) functionality, it also _disabled_ the TRIM_UNUSED_KSYMS
functionality.
And it turns out that TRIM_UNUSED_KSYMS is a huge time waste, and takes
up a third of the kernel build time for me. For no actual upside, since
no distro is likely to ever be able to enable it (because they all
support external kernel modules).
Rather than re-enable EXPORT_UNUSED_SYMBOL, this just disables the
TRIM_UNUSED_KSYMS option by marking it broken. I'm tempted to just
remove the support entirely, but maybe somebody has a use-case and can
fix the behavior of it.
I could have just disabled it for COMPILE_TEST, but it really smells
like the TRIM_UNUSED_KSYMS option is badly done and not really useful,
so this takes the more direct approach - let's see if anybody ever
actually notices or complains.

This is built on the work done preparing for LTO by arm64 folks,

Pull tracing updates from Steven Rostedt:
- Update to the way irqs and preemption is tracked via the trace event
PC field
- Fix handling of unregistering event failing due to allocate memory.
This is only triggered by failure injection, as it is pretty much
guaranteed to have less than a page allocation succeed.
- Do not show the useless "filter" or "enable" files for the "ftrace"
trace system, as they have no effect on doing anything.
- Add a warning if kprobes are registered more than once.
- Synthetic events now have their fields parsed by semicolons. Old
formats without semicolons will still work, but new features will
require them.
- New option to allow trace events to show %p without hashing in trace
file. The trace file can only be read by root, and reading the raw
event buffer did not have any pointers hashed, so this does not
expose anything new.
- New directory in tools called tools/tracing, where a new tool that
reads sequential latency reports from the ftrace latency tracers.
- Other minor fixes and cleanups.

Pull perf tool updates from Arnaldo Carvalho de Melo:
"New features:
- Support instruction latency in 'perf report', with both memory
latency (weight) and instruction latency information, users can
locate expensive load instructions and understand time spent in
different stages.
- Extend 'perf c2c' to display the number of loads which were blocked
by data or address conflict.
- Add 'perf stat' support for L2 topdown events in systems such as
Intel's Sapphire rapids server.
- Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a
sort key, for instance:
perf report --stdio --sort=comm,symbol,code_page_size
- New 'perf daemon' command to run long running sessions while
providing a way to control the enablement of events without
restarting a traditional 'perf record' session.
- Enable counting events for BPF programs in 'perf stat' just like
for other targets (tid, cgroup, cpu, etc), e.g.:
# perf stat -e ref-cycles,cycles -b 254 -I 1000
1.487903822 115,200 ref-cycles
1.487903822 86,012 cycles
2.489147029 80,560 ref-cycles
2.489147029 73,784 cycles
^C
The example above counts 'cycles' and 'ref-cycles' of BPF program
of id 254. It is similar to bpftool-prog-profile command, but more
flexible.
- Support the new layout for PERF_RECORD_MMAP2 to carry the DSO
build-id using infrastructure generalised from the eBPF subsystem,
removing the need for traversing the perf.data file to collect
build-ids at the end of 'perf record' sessions and helping with
long running sessions where binaries can get replaced in updates,
leading to possible mis-resolution of symbols.
- Support filtering by hex address in 'perf script'.
- Support DSO filter in 'perf script', like in other perf tools.
- Add namespaces support to 'perf inject'
- Add support for SDT (Dtrace Style Markers) events on ARM64.
perf record:
- Fix handling of eventfd() when draining a buffer in 'perf record'.
- Improvements to the generation of metadata events for pre-existing
threads (mmaps, comm, etc), speeding up the work done at the start
of system wide or per CPU 'perf record' sessions.
Hardware tracing:
- Initial support for tracing KVM with Intel PT.
- Intel PT fixes for IPC
- Support Intel PT PSB (synchronization packets) events.
- Automatically group aux-output events to overcome --filter syntax.
- Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.
- Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.
perf annotate TUI:
- Fix handling of 'k' ("show line number") hotkey
- Fix jump parsing for C++ code.
perf probe:
- Add protection to avoid endless loop.
cgroups:
- Avoid reading cgroup mountpoint multiple times, caching it.
- Fix handling of cgroup v1/v2 in mixed hierarchy.
Symbol resolving:
- Add OCaml symbol demangling.
- Further fixes for handling PE executables when using perf with Wine
and .exe/.dll files.
- Fix 'perf unwind' DSO handling.
- Resolve symbols against debug file first, to deal with artifacts
related to LTO.
- Fix gap between kernel end and module start on powerpc.
Reporting tools:
- The DSO filter shouldn't show samples in unresolved maps.
- Improve debuginfod support in various tools.
build ids:
- Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test'
entry for that case.
perf test:
- Support for PERF_SAMPLE_WEIGHT_STRUCT.
- Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.
- Shell based tests for 'perf daemon's commands ('start', 'stop,
'reconfig', 'list', etc).
- ARM cs-etm 'perf test' fixes.
- Add parse-metric memory bandwidth testcase.
Compiler related:
- Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used
with -fpatchable-function-entry.
- Fix ARM64 build with gcc 11's -Wformat-overflow.
- Fix unaligned access in sample parsing test.
- Fix printf conversion specifier for IP addresses on arm64, s390 and
powerpc.
Arch specific:
- Support exposing Performance Monitor Counter SPRs as part of
extended regs on powerpc.
- Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn
DDR, fix imx8mm ones.

- Fix DM integrity's HMAC support to provide enhanced security of
internal_hash and journal_mac capabilities.
- Various DM writecache fixes to address performance, fix table output
to match what was provided at table creation, fix writing beyond end
of device when shrinking underlying data device, and a couple other
small cleanups.
- Add DM crypt support for using trusted keys.
- Fix deadlock when swapping to DM crypt device by throttling number of
in-flight REQ_SWAP bios. Implemented in DM core so that other
bio-based targets can opt-in by setting ti->limit_swap_bios.
- Fix various inverted logic bugs in the .iterate_devices callout
functions that are used to assess if specific feature or capability
is supported across all devices being combined/stacked by DM.
- Fix DM era target bugs that exposed users to lost writes or memory
leaks.
- Add DM core support for passing through inline crypto support of
underlying devices. Includes block/keyslot-manager changes that
enable extending this support to DM.

"This is all driver updates, the majority of which is a bunch of new
Qualcomm clk drivers that dominate the diffstat because we add support
for six SoCs from that particular vendor.
The other big change is the removal of various clk drivers that are no
longer used now that the kernel is dropping support for those SoCs.
Beyond that there's the usual non-critical fixes for existing drivers
and a good number of patches from Lee Jones that cleanup a bunch of
W=1 enabled builds.
