Linus Torvalds 0dca3c5e01 ARM: defconfig updates for 5.17
These are the usual changes to enable newly added driver
 by default, and to do some housekeeping around changing
 Kconfig symbols.

Nikita Travkin cf73ed894e Input: zinitix - make sure the IRQ is allocated before it gets enabled
Since irq request is the last thing in the driver probe, it happens
later than the input device registration. This means that there is a
small time window where if the open method is called the driver will
attempt to enable not yet available irq.

Fix that by moving the irq request before the input device registration.

  to enable quirks in the driver.
  - A runtime PM fix for Renesas to fix mismatched reference counts on
  errors.

Greg Kroah-Hartman 0704a8586f s390/dasd: use default_groups in kobj_type
There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the s390 dasd sysfs code to use default_groups field
which has been the preferred way since commit aa30f47cf6 ("kobject:
Add support for default attribute groups to kobj_type") so that we can
soon get rid of the obsolete default_attrs field.

Greg Kroah-Hartman 1350f36d38 s390/sclp_sd: use default_groups in kobj_type
There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the sclp_sd sysfs code to use default_groups field which
has been the preferred way since commit aa30f47cf6 ("kobject: Add
support for default attribute groups to kobj_type") so that we can
soon get rid of the obsolete default_attrs field.

Wolfram Sang a19f75de73 Revert "i2c: core: support bus regulator controlling in adapter"
This largely reverts commit 5a7b95fb99. It
breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So,
let's remove the code and go back to the drawing board. We keep the
header extension to not break drivers already populating the regulator.
We expect to re-add the code handling it soon.

Arnaldo Carvalho de Melo dc9f2dd5de Revert "libtraceevent: Increase libtraceevent logging when verbose"
This reverts commit 08efcb4a63.

This breaks the build as it will prefer using libbpf-devel header files,
even when not using LIBBPF_DYNAMIC=1, breaking the build.

This was detected on OpenSuSE Tumbleweed with libtraceevent-devel 1.3.0,
as described by Jiri Slaby:

=======================================================================
It breaks build with LIBTRACEEVENT_DYNAMIC and version 1.3.0:
> util/debug.c: In function ‘perf_debug_option’:
> util/debug.c:243:17: error: implicit declaration of function
‘tep_set_loglevel’ [-Werror=implicit-function-declaration]

It is because the gcc's command line looks like:
gcc
...
-I/home/abuild/rpmbuild/BUILD/tools/lib/
...
-DLIBTRACEEVENT_VERSION=65790
...
=======================================================================

The proper way to fix this is more involved and so not suitable for this
late in the 5.16-rc stage.

Jiri Olsa f06a82f9d3 perf trace: Avoid early exit due to running SIGCHLD handler before it makes sense to
When running 'perf trace' with an BPF object like:

  # perf trace -e openat,tools/perf/examples/bpf/hello.c

the event parsing eventually calls llvm__get_kbuild_opts() that runs a
script and that ends up with SIGCHLD delivered to the 'perf trace'
handler, which assumes the workload process is done and quits 'perf
trace'.

Move the SIGCHLD handler setup directly to trace__run(), where the event
is parsed and the object is already compiled.

Dave Hansen 2056e2989b x86/sgx: Fix NULL pointer dereference on non-SGX systems
== Problem ==

Nathan Chancellor reported an oops when aceessing the
'sgx_total_bytes' sysfs file:

	https://lore.kernel.org/all/YbzhBrimHGGpddDM@archlinux-ax161/

The sysfs output code accesses the sgx_numa_nodes[] array
unconditionally.  However, this array is allocated during SGX
initialization, which only occurs on systems where SGX is
supported.

If the sysfs file is accessed on systems without SGX support,
sgx_numa_nodes[] is NULL and an oops occurs.

== Solution ==

To fix this, hide the entire nodeX/x86/ attribute group on
systems without SGX support using the ->is_visible attribute
group callback.

Unfortunately, SGX is initialized via a device_initcall() which
occurs _after_ the ->is_visible() callback.  Instead of moving
SGX initialization earlier, call sysfs_update_group() during
SGX initialization to update the group visiblility.

This update requires moving the SGX sysfs code earlier in
sgx/main.c.  There are no code changes other than the addition of
arch_update_sysfs_visibility() and a minor whitespace fixup to
arch_node_attr_is_visible() which checkpatch caught.

Tejun Heo bf35a7879f selftests: cgroup: Test open-time cgroup namespace usage for migration checks
When a task is writing to an fd opened by a different task, the perm check
should use the cgroup namespace of the latter task. Add a test for it.

Tejun Heo b09c2baa56 selftests: cgroup: Make cg_create() use 0755 for permission instead of 0644
0644 is an odd perm to create a cgroup which is a directory. Use the regular
0755 instead. This is necessary for euid switching test case.

Tejun Heo e574576416 cgroup: Use open-time cgroup namespace for process migration perm checks
cgroup process migration permission checks are performed at write time as
whether a given operation is allowed or not is dependent on the content of
the write - the PID. This currently uses current's cgroup namespace which is
a potential security weakness as it may allow scenarios where a less
privileged process tricks a more privileged one into writing into a fd that
it created.

This patch makes cgroup remember the cgroup namespace at the time of open
and uses it for migration permission checks instad of current's. Note that
this only applies to cgroup2 as cgroup1 doesn't have namespace support.

This also fixes a use-after-free bug on cgroupns reported in

 https://lore.kernel.org/r/00000000000048c15c05d0083397@google.com

Note that backporting this fix also requires the preceding patch.

Tejun Heo 0d2b5955b3 cgroup: Allocate cgroup_file_ctx for kernfs_open_file->priv
of->priv is currently used by each interface file implementation to store
private information. This patch collects the current two private data usages
into struct cgroup_file_ctx which is allocated and freed by the common path.
This allows generic private data which applies to multiple files, which will
be used to in the following patch.

Note that cgroup_procs iterator is now embedded as procs.iter in the new
cgroup_file_ctx so that it doesn't need to be allocated and freed
separately.

v2: union dropped from cgroup_file_ctx and the procs iterator is embedded in
    cgroup_file_ctx as suggested by Linus.

v3: Michal pointed out that cgroup1's procs pidlist uses of->priv too.
    Converted. Didn't change to embedded allocation as cgroup1 pidlists get
    stored for caching.

Tejun Heo 1756d7994a cgroup: Use open-time credentials for process migraton perm checks
cgroup process migration permission checks are performed at write time as
whether a given operation is allowed or not is dependent on the content of
the write - the PID. This currently uses current's credentials which is a
potential security weakness as it may allow scenarios where a less
privileged process tricks a more privileged one into writing into a fd that

This patch makes both cgroup2 and cgroup1 process migration interfaces to
use the credentials saved at the time of open (file->f_cred) instead of
current's.

osnoise tracer on ppc64le is triggering osnoise_taint() for negative
duration in get_int_safe_duration() called from
trace_sched_switch_callback()->thread_exit().

The problem though is that the check for a valid trace_percpu_buffer is
incorrect in get_trace_buf(). The check is being done after calculating
the pointer for the current cpu, rather than on the main percpu pointer.
Fix the check to be against trace_percpu_buffer.

Jiri Olsa 0daf5cb217 ftrace/samples: Add missing prototypes direct functions
There's another compilation fail (first here [1]) reported by kernel

  prototype for function 'my_direct_func1' [-Wmissing-prototypes]
     void my_direct_func1(unsigned long ip)

Direct functions in ftrace direct sample modules need to have prototypes
defined. They are already global in order to be visible for the inline
assembly, so there's no problem.

The kernel test robot reported just error for ftrace-direct-multi-modify,
but I got same errors also for the rest of the modules touched by this patch.

====================
pull-request: ieee802154 for net 2022-01-05

Below I have a last minute fix for the atusb driver.

Pavel fixes a KASAN uninit report for the driver. This version is the
minimal impact fix to ease backporting. A bigger rework of the driver to
avoid potential similar problems is ongoing and will come through net-next
when ready.
