Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

Driver core / debugfs update for 5.12-rc1
Here is the "big" driver core and debugfs update for 5.12-rc1
This set of driver core patches caused a bunch of problems in linux-next
for the past few weeks, when Saravana tried to set fw_devlink=on as the
default functionality. This caused a number of systems to stop booting,
and lots of bugs were fixed in this area for almost all of the reported
systems, but this option is not ready to be turned on just yet for the
default operation based on this testing, so I've reverted that change at
the very end so we don't have to worry about regressions in 5.12. We
will try to turn this on for 5.13 if testing goes better over the next
few months.
Other than the fixes caused by the fw_devlink testing in here, there's
not much more:
- debugfs fixes for invalid input into debugfs_lookup()
- kerneldoc cleanups
- warn message if platform drivers return an error on their
remove callback (a futile effort, but good to catch).
All of these have been in linux-next for a while now, and the
regressions have gone away with the revert of the fw_devlink change.

It has been a relatively quiet cycle in docsland.
- As promised, the minimum Sphinx version to build the docs is now 1.7,
and we have dropped support for Python 2 entirely. That allowed the
removal of a bunch of compatibility code.
- A set of treewide warning fixups from Mauro that I applied after it
became clear nobody else was going to deal with them.
- The automarkup mechanism can now create cross-references from relative
paths to RST files.
- More translations, typo fixes, and warning fixes.
No conflicts with any other tree as far as I know.

The performance event updates for v5.12 are:
- Add CPU-PMU support for Intel Sapphire Rapids CPUs
- Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter
sampling event feedback. Not used yet, but is intended for Golden Cove
CPU-PMU, which can provide both the instruction latency and the cache
latency information for memory profiling events.
- Remove experimental, default-disabled perfmon-v4 counter_freezing support
that could only be enabled via a boot option. The hardware is hopelessly
broken, we'd like to make sure nobody starts relying on this, as it would
only end in tears.
- Fix energy/power events on Intel SPR platforms
- Simplify the uprobes resume_execution() logic
- Misc smaller fixes.

Scheduler updates for v5.12:
[ NOTE: unfortunately this tree had to be freshly rebased today,
it's a same-content tree of 82891be90f3c (-next published)
merged with v5.11.
The main reason for the rebase was an authorship misattribution
problem with a new commit, which we noticed in the last minute,
and which we didn't want to be merged upstream. The offending
commit was deep in the tree, and dependent commits had to be
rebased as well. ]
- Core scheduler updates:
- Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
preempt=none/voluntary/full boot options (default: full),
to allow distros to build a PREEMPT kernel but fall back to
close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling
behavior via a boot time selection.
There's also the /debug/sched_debug switch to do this runtime.
This feature is implemented via runtime patching (a new variant of static calls).
The scope of the runtime patching can be best reviewed by looking
at the sched_dynamic_update() function in kernel/sched/core.c.
( Note that the dynamic none/voluntary mode isn't 100% identical,
for example preempt-RCU is available in all cases, plus the
preempt count is maintained in all models, which has runtime
overhead even with the code patching. )
The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast majority
of distributions, are supposed to be unaffected.
- Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
was found via rcutorture triggering a hang. The bug is that
rcu_idle_enter() may wake up a NOCB kthread, but this happens after
the last generic need_resched() check. Some cpuidle drivers fix it
by chance but many others don't.
In true 2020 fashion the original bug fix has grown into a 5-patch
scheduler/RCU fix series plus another 16 RCU patches to address
the underlying issue of missed preemption events. These are the
initial fixes that should fix current incarnations of the bug.
- Clean up rbtree usage in the scheduler, by providing & using the following
consistent set of rbtree APIs:
partial-order; less() based:
- rb_add(): add a new entry to the rbtree
- rb_add_cached(): like rb_add(), but for a rb_root_cached
total-order; cmp() based:
- rb_find(): find an entry in an rbtree
- rb_find_add(): find an entry, and add if not found
- rb_find_first(): find the first (leftmost) matching entry
- rb_next_match(): continue from rb_find_first()
- rb_for_each(): iterate a sub-tree using the previous two
- Improve the SMP/NUMA load-balancer: scan for an idle sibling in a single pass.
This is a 4-commit series where each commit improves one aspect of the idle
sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU utilization
metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by reducing the number
of active LB attempts & lengthen the load-balancing interval. This improves
stress-ng mmapfork performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can result in
too high utilization values
- Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()
- Clean up task priority related defines, remove *USER_*PRIO and
USER_PRIO()
- Simplify the sched_init_numa() deduplication sort
- Documentation updates
- Fix EAS bug in update_misfit_status(), which degraded the quality
of energy-balancing
- Smaller cleanups

one aspect of the idle sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU
utilization metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by
reducing the number of active LB attempts & lengthen the
load-balancing interval. This improves stress-ng mmapfork
performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can
result in too high utilization values
Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()
- Clean up task priority related defines, remove *USER_*PRIO and
USER_PRIO()
- Simplify the sched_init_numa() deduplication sort
- Documentation updates
- Fix EAS bug in update_misfit_status(), which degraded the quality
of energy-balancing
- Smaller cleanups"

Remove oprofile and dcookies support

New code for 5.12:
- Fix an ABBA deadlock when renaming files on overlayfs.
- Make sure that we can't overflow the inode extent counters when adding
to or removing extents from a file.
- Make directory sgid inheritance work the same way as all the other
filesystems.
- Don't drain the buffer cache on freeze and ro remount, which should
reduce the amount of time if read-only workloads are continuing
during the freeze.
- Fix a bug where symlink size isn't reported to the vfs in ecryptfs.
- Disentangle log cleaning from log covering. This refactoring sets us
up for future changes to the log, though for now it simply means that
we can use covering for freezes, and cleaning becomes something we
only do at unmount.
- Speed up file fsyncs by reducing iolock cycling.
- Fix delalloc blocks leaking when changing the project id fails because
of input validation errors in FSSETXATTR.
- Fix oversized quota reservation when converting unwritten extents
during a DAX write.
- Create a transaction allocation helper function to standardize the
idiom of allocating a transaction, reserving blocks, locking inodes,
and reserving quota. Replace all the open-coded logic for file
creation, file ownership changes, and file modifications to use them.
- Actually shut down the fs if the incore quota reservations get
corrupted.
- Fix background block garbage collection scans to not block and to
actually clean out CoW staging extents properly.
- Run block gc scans when we run low on project quota.
- Use the standardized transaction allocation helpers to make it so that
ENOSPC and EDQUOT errors during reservation will back out, invoke the
block gc scanner, and try again. This is preparation for introducing
background inode garbage collection in the next cycle.
- Combine speculative post-EOF block garbage collection with speculative
copy on write block garbage collection.
- Enable multithreaded quotacheck.
- Allow sysadmins to tweak the CPU affinities and maximum concurrency
levels of quotacheck and background blockgc worker pools.
- Expose the inode btree counter feature in the fs geometry ioctl.
- Cleanups of the growfs code in preparation for starting work on
filesystem shrinking.
- Fix all the bloody gcc warnings that the maintainer knows about. :P
- Fix a RST syntax error.
- Don't trigger bmbt corruption assertions after the fs shuts down.
- Restore behavior of forcing SIGBUS on a shut down filesystem when
someone triggers a mmap write fault (or really, any buffered write).

Pull xfs updates from Darrick Wong:
"There's a lot going on this time, which seems about right for this
drama-filled year.
Community developers added some code to speed up freezing when
read-only workloads are still running, refactored the logging code,
added checks to prevent file extent counter overflow, reduced iolock
cycling to speed up fsync and gc scans, and started the slow march
towards supporting filesystem shrinking.
There's a huge refactoring of the internal speculative preallocation
garbage collection code which fixes a bunch of bugs, makes the gc
scheduling per-AG and hence multithreaded, and standardizes the retry
logic when we try to reserve space or quota, can't, and want to
trigger a gc scan. We also enable multithreaded quotacheck to reduce
mount times further. This is also preparation for background file gc,
which may or may not land for 5.13.
We also fixed some deadlocks in the rename code, fixed a quota
accounting leak when FSSETXATTR fails, restored the behavior that
write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
where sgid directory inheritance wasn't quite working properly, and
fixed a bug where symlinks weren't working properly in ecryptfs. We
also now advertise the inode btree counters feature that was
introduced two cycles ago.
Summary:
- Fix an ABBA deadlock when renaming files on overlayfs.
- Make sure that we can't overflow the inode extent counters when
adding to or removing extents from a file.
- Make directory sgid inheritance work the same way as all the other
filesystems.
- Don't drain the buffer cache on freeze and ro remount, which should
reduce the amount of time if read-only workloads are continuing

preempt: Introduce CONFIG_PREEMPT_DYNAMIC
Preemption mode selection is currently hardcoded on Kconfig choices. Introduce a dedicated option to tune preemption flavour at boot time, This will be only available on architectures efficiently supporting static calls in order not to tempt with the feature against additional overhead that might be prohibitive or undesirable. CONFIG_PREEMPT_DYNAMIC is automatically selected by CONFIG_PREEMPT if the architecture provides the necessary support (CONFIG_STATIC_CALL_INLINE, CONFIG_GENERIC_ENTRY, and provide with __preempt_schedule_function() / __preempt_schedule_notrace_function()).

lib/vsprintf: no_hash_pointers prints all addresses as unhashed
If the no_hash_pointers command line parameter is set, then
printk("%p") will print pointers as unhashed, which is useful for
debugging purposes. This change applies to any function that uses
vsprintf, such as print_hex_dump() and seq_buf_printf().
A large warning message is displayed if this option is enabled.
Unhashed pointers expose kernel addresses, which can be a security
risk.
Also update test_printf to skip the hashed pointer tests if the
command-line option is set.

There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real

entry: Use different define for selector variable in SUD
Michael Kerrisk suggested that, from an API perspective, it is a bad idea to share the PR_SYS_DISPATCH_ defines between the prctl operation and the selector variable. Therefore, define two new constants to be used by SUD's selector variable and update the corresponding documentation and test cases. While this changes the API syscall user dispatch has never been part of a Linux release, it will show up for the first time in 5.11.

thunderbolt: Add support for PCIe tunneling disabled (SL5)
Recent Intel Thunderbolt firmware connection manager has support for another security level, SL5, that disables PCIe tunneling. This option can be turned on from the BIOS. When this is set the driver exposes a new security level "nopcie" to the userspace and hides the authorized attribute under connected devices. While there we also hide it when "dponly" security level is enabled since it is not really usable in that case anyway.

xfs: increase the default parallelism levels of pwork clients
Increase the parallelism level for pwork clients to the workqueue defaults so that we can take advantage of computers with a lot of CPUs and a lot of hardware. On fast systems this will speed up quotacheck by a large factor, and the following posteof/cowblocks cleanup series will use the functionality presented in this patch to run garbage collection as quickly as possible. We do this by switching the pwork workqueue to unbounded, since the current user (quotacheck) runs lengthy scans for each work item and we don't care about dispatching the work on a warm cpu cache or anything like that. Also set WQ_SYSFS so that we can monitor where the wq is running. Signed-off-by: Darrick J.

perf/arm-cmn: Fix PMU instance naming
Although it's neat to avoid the suffix for the typical case of a
single PMU, it means systems with multiple CMN instances end up with
inconsistent naming. I think it also breaks perf tool's "uncore alias"
logic if the common instance prefix is also the full name of one.
Avoid any surprises by not trying to be clever and simply numbering
every instance, even when it might technically prove redundant.

media: rockchip: rkisp1: carry ip version information
The IP block evolved from its rk3288/rk3399 base and the vendor designates them with a numerical version. rk3399 for example is designated V10 probably meaning V1.0. There doesn't seem to be an actual version register we could read that information from, so allow the match_data to carry that information for future differentiation. Also carry that information in the hw_revision field of the media- controller API, so that userspace also has access to that. The added versions are: - V10: at least rk3288 + rk3399 - V11: seemingly unused as of now, but probably appeared in some soc - V12: at least rk3326 + px30 - V13: at least rk1808 [fix checkpatch warning don't use multiple blank lines] Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Reviewed-by: Ezequiel Garcia <ezequiel@collabora.com> Acked-by: Helen Koike <helen.koike@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

perf/intel: Remove Perfmon-v4 counter_freezing support
Perfmon-v4 counter freezing is fundamentally broken; remove this default disabled code to make sure nobody uses it. The feature is called Freeze-on-PMI in the SDM, and if it would do that, there wouldn't actually be a problem, *however* it does something subtly different. It globally disables the whole PMU when it raises the PMI, not when the PMI hits. This means there's a window between the PMI getting raised and the PMI actually getting served where we loose events and this violates the perf counter independence. That is, a counting event should not result in a different event count when there is a sampling event co-scheduled. This is known to break existing software (RR).

dm integrity: conditionally disable "recalculate" feature
Otherwise a malicious user could (ab)use the "recalculate" feature that makes dm-integrity calculate the checksums in the background while the device is already usable. When the system restarts before all checksums have been calculated, the calculation continues where it was interrupted even if the recalculate feature is not requested the next time the dm device is set up. Disable recalculating if we use internal_hash or journal_hash with a key (e.g. HMAC) and we don't have the "legacy_recalculate" flag. This may break activation of a volume, created by an older kernel, that is not yet fully recalculated -- if this happens, the user should add the "legacy_recalculate" flag to constructor parameters.

thunderbolt: Add support for de-authorizing devices
In some cases it is useful to be able de-authorize devices. For example if user logs out the userspace can have a policy that disconnects PCIe devices until logged in again. This is only possible for software based connection manager as it directly controls the tunnels. For this reason make the authorized attribute accept writing 0 which makes the software connection manager to tear down the corresponding PCIe tunnel. Userspace can check if this is supported by reading a new domain attribute deauthorization, that holds 1 in that case. While there correct tb_domain_approve_switch() kernel-doc and description of authorized attribute to mention that it is only about PCIe tunnels.

rcu: Enable rcu_normal_after_boot unconditionally for RT
Expedited RCU grace periods send IPIs to all non-idle CPUs, and thus can disrupt time-critical code in real-time applications. However, there is a portion of boot-time processing (presumably before any real-time applications have started) where expedited RCU grace periods are the only option. And so it is that experience with the -rt patchset indicates that PREEMPT_RT systems should always set the rcupdate.rcu_normal_after_boot kernel boot parameter. This commit therefore makes the post-boot application environment safe for real-time applications by making PREEMPT_RT systems disable the rcupdate.rcu_normal_after_boot kernel boot parameter and acting as if this parameter had been set. This means that post-boot calls to synchronize_rcu_expedited() will be treated as if they were instead calls to synchronize_rcu(), thus preventing the IPIs, and thus avoiding disrupting real-time applications.

rcu: Unconditionally use rcuc threads on PREEMPT_RT
PREEMPT_RT systems have long used the rcutree.use_softirq kernel boot parameter to avoid use of RCU_SOFTIRQ handlers, which can disrupt real-time applications by invoking callbacks during return from interrupts that arrived while executing time-critical code. This kernel boot parameter instead runs RCU core processing in an 'rcuc' kthread, thus allowing the scheduler to do its job of avoiding disrupting time-critical code. This commit therefore disables the rcutree.use_softirq kernel boot parameter on PREEMPT_RT systems, thus forcing such systems to do RCU core processing in 'rcuc' kthreads. This approach has long been in use by users of the -rt patchset, and there have been no complaints. There is therefore no way for the system administrator to override this choice, at least without modifying and rebuilding the kernel.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.
There is a trivial conflict in the cedrus driver, with two branches
adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
remove/remove conflict in linux/dma-mapping.h.

mm/lru: revise the comments of lru_lock
Since we changed the pgdat->lru_lock to lruvec->lru_lock, it's time to fix the incorrect comments in code. Also fixed some zone->lru_lock comment error from ancient time. etc. I struggled to understand the comment above move_pages_to_lru() (surely it never calls page_referenced()), and eventually realized that most of it had got separated from shrink_active_list(): move that comment back.

zram: add stat to gather incompressible pages since zram set up
Currently, zram supports the stat via /sys/block/zram/mm_stat to represent how many of incompressible pages are stored at the moment but it couldn't show how many times incompressible pages were wrote down since zram set up. It's also good indication to see how zram is effective in the system.

zram: support page writeback
There is demand to writeback specific process pages to backing store instead of all idles pages in the system due to storage wear out concerns and to launching latency of apps which are most of the time idle but are critical for resume latency.

userfaultfd: add user-mode only option to unprivileged_userfaultfd sysctl knob
With this change, when the knob is set to 0, it allows unprivileged users to call userfaultfd, like when it is set to 1, but with the restriction that page faults from only user-mode can be handled. In this mode, an unprivileged user (without SYS_CAP_PTRACE capability) must pass UFFD_USER_MODE_ONLY to userfaultd or the API will fail with EPERM. This enables administrators to reduce the likelihood that an attacker with access to userfaultfd can delay faulting kernel code to widen timing windows for other exploits. The default value of this knob is changed to 0. This is required for correct functioning of pipe mutex. However, this will fail postcopy live migration, which will be unnoticeable to the VM guests. To avoid this, set 'vm.userfault = 1' in /sys/sysctl.conf. The main reason this change is desirable as in the short term is that the Android userland will behave as with the sysctl set to zero. So without this commit, any Linux binary using userfaultfd to manage its memory would behave differently if run within the Android userland. For more details, refer to Andrea's reply [1].

mm: memcontrol: account pagetables per node
For many workloads, pagetable consumption is significant and it makes sense to expose it in the memory.stat for the memory cgroups. However at the moment, the pagetables are accounted per-zone. Converting them to per-node and using the right interface will correctly account for the memory cgroups as well.

mm: memcontrol: add file_thp, shmem_thp to memory.stat
As huge page usage in the page cache and for shmem files proliferates in our production environment, the performance monitoring team has asked for per-cgroup stats on those pages. We already track and export anon_thp per cgroup. We already track file THP and shmem THP per node, so making them per-cgroup is only a matter of switching from node to lruvec counters. All callsites are in places where the pages are charged and locked, so page->memcg is stable.

A set of updates for entry/exit handling:
- More generalization of entry/exit functionality
- The consolidation work to reclaim TIF flags on x86 and also for non-x86
specific TIF flags which are solely relevant for syscall related work
and have been moved into their own storage space. The x86 specific part
had to be merged in to avoid a major conflict.
- The TIF_NOTIFY_SIGNAL work which replaces the inefficient signal
delivery mode of task work and results in an impressive performance
improvement for io_uring. The non-x86 consolidation of this is going to
come seperate via Jens.
- The selective syscall redirection facility which provides a clean and
efficient way to support the non-Linux syscalls of WINE by catching them
at syscall entry and redirecting them to the user space emulation. This
can be utilized for other purposes as well and has been designed
carefully to avoid overhead for the regular fastpath. This includes the
core changes and the x86 support code.
- Simplification of the context tracking entry/exit handling for the users
of the generic entry code which guarantee the proper ordering and
protection.
- Preparatory changes to make the generic entry code accomodate S390
specific requirements which are mostly related to their syscall restart
mechanism.

- Italian translation updates
- A mechanism from Mauro to automatically format Documentation/features

- Automatic cross references without explicit :ref: markup
- A new reset-controller document

"Intel SGX is new hardware functionality that can be used by
applications to populate protected regions of user code and data called enclaves. Once activated, the new hardware protects enclave code and data from outside access and modification. Enclaves provide a place to store secrets and process data with those secrets.

docs: Add a new text describing how to report bugs
Add a mostly finished document describing how to report issues with the Linux kernel to its developers. It is designed to be a lot more straight forward and easier to follow than the current text about this (Documentation/admin-guide/reporting-bugs.rst); at the same time the new text should be more helpful for people unfamiliar with the topic, as it provides a lot more details, too. The main work on the text is done, but some polishing is still needed. The text also needs to be reviewed by more people and a few issues still might need some discussion. To make these tasks easier, it was decided ([1]) to add this document to the kernel sources in parallel to the existing text; the latter will be removed once this text is considered good enough(tm). This document is quite long and provides a lot of details, but was carefully crafted to make sure it's can also serve people that are in a hurry. That's mainly achieved by having a TDLR and a step-by-step guide, which should be good enough for quite a lot of people. Everybody that wants or need more explanations can find them in a reference section, which describes all the needed steps in detail. Thanks to this structure the text can work for kernel developers that just need to look something up, experienced FLOSS contributors that are unfamiliar with the kernel's bug reporting workflow, and users reporting something upstream for the first time. The text is thus a bit like the kernel itself, which works well for embedded machines, a typical desktop PC, cloud servers, and HPC. The document was written in the hope it will improve the quality of the bug reports, especially those that come from people unfamiliar with how Linux kernel development works. Sadly quite a few reports from this group are currently of poor quality and/or get submitted to the wrong place. Part of the problem is the old reporting-bugs document, as it makes its essence hard to grasp; it's and also inaccurate and slightly outdated in a few spots. Due to this quite a few valid reports are ignored in the end, which is annoying for those that compiled them and bad for the kernel's quality. The document near the top points out that it's still unfinished, but nevertheless ready for consumption. Those few areas in the text that might need some further discussion contain a note pointing this out. Besides lack of review from core developers there is only one major issue left: the section 'Decode failure message' is known to be outdated: it's waiting for someone familiar with the topic to write something up or give at least provide some hints and pointers what to write there. The new document is dual-licensed under GPL-2.0+ or CC-BY-4.0. The latter is way more liberal and makes it attractive to use this text as a base when writing about this topic on websites or in books. This hopefully increases the chances that such texts are accurate and stick to official way of doing things.

dm verity: Add support for signature verification with 2nd keyring
Add a new configuration DM_VERITY_VERIFY_ROOTHASH_SIG_SECONDARY_KEYRING to enable dm-verity signatures to be verified against the secondary trusted keyring. Instead of relying on the builtin trusted keyring (with hard-coded certificates), the second trusted keyring can include certificate authorities from the builtin trusted keyring and child certificates loaded at run time. Using the secondary trusted keyring enables to use dm-verity disks (e.g. loop devices) signed by keys which did not exist at kernel build time, leveraging the certificate chain of trust model. In practice, this makes it possible to update certificates without kernel update and reboot, aligning with module and kernel (kexec) signature verification which already use the secondary trusted keyring.

KVM: arm64: Add kvm-arm.mode early kernel parameter
Add an early parameter that allows users to select the mode of operation for KVM/arm64. For now, the only supported value is "protected". By passing this flag users opt into the hypervisor placing additional restrictions on the host kernel. These allow the hypervisor to spawn guests whose state is kept private from the host. Restrictions will include stage-2 address translation to prevent host from accessing guest memory, filtering its SMC calls, etc. Without this parameter, the default behaviour remains selecting VHE/nVHE based on hardware support and CONFIG_ARM64_VHE.

powerpc fixes for CVE-2020-4788
From Daniel's cover letter: IBM Power9 processors can speculatively operate on data in the L1 cache before it has been completely validated, via a way-prediction mechanism. It is not possible for an attacker to determine the contents of impermissible memory using this method, since these systems implement a combination of hardware and software security measures to prevent scenarios where protected data could be leaked. However these measures don't address the scenario where an attacker induces the operating system to speculatively execute instructions using data that the attacker controls. This can be used for example to speculatively bypass "kernel user access prevention" techniques, as discovered by Anthony Steinhauser of Google's Safeside Project. This is not an attack by itself, but there is a possibility it could be used in conjunction with side-channels or other weaknesses in the privileged code to construct an attack. This issue can be mitigated by flushing the L1 cache between privilege boundaries of concern. This patch series flushes the L1 cache on kernel entry (patch 2) and after the kernel performs any user accesses (patch 3). It also adds a self-test and performs some related cleanups. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAl+2aqETHG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgG+hD/4njSFct2amqWfqDYR9b2OykWmnMQXn geookk5SbItQF7vh1q2SVA6r43s5ZAxgD5fezx4LgG6p3QU39+Tr0RhzUUHWMPDV UNGZK6x/N/GSYeq0bqvMHmVwS0FDjPE8nOtA8Hn2T9mUUsu9G0okpgYPLnEu6rb1 gIyS35zlLBh9obi3MfJzyln/AmCE7hdonKRtLAxvGiERJAyfAG757lrdjrwavyHy mwz+XPl5PF88jfO5cbcZT9gNHmZZPzVsOVwNcstCh2FcwuePv9dWe1pxsBxxKqP5 UXceXPcKM7VlRNmehimq7q/hfbget4RJGGKYPNXeKHOo6yfy7lJPiQV4h+5z2pSs SPP2fQQPq0aubmcO23CXFtZl4WRHQ4pax6opepnpIfC2vZ0HLXJtPrhMKcbFJNTo qPis6HWQPpIuI6l4MJfs+YO9ETxCR31Yd28qFAfPFoHlnQZTfx6NPhw8HKxTbSh2 Svr4X6Y14j3UsQgLTCArCXWAG/hlfRwxDZJ4AvR9EU0HJGDyZ45Y+LTD1N8bbsny zcYfPqWGPIanLcNPNFYIQwDZo7ff08KdmngUvf/Q9om60mP1hsPJMHf6VhPXj4fC 2TZ11fORssSlBSNtIkFkbjEG+aiWtWnz3fN3uSyT50rgGwtDHJzVzLiUWHlZKcxW X73YdxuT8fqQwg== =Yibq -----END PGP SIGNATURE----- Merge tag 'powerpc-cve-2020-4788' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "Fixes for CVE-2020-4788.
