lockdep: Refactor IRQ trace events fields into struct
Refactor the IRQ trace events fields, used for printing information about the IRQ trace events, into a separate struct 'irqtrace_events'. This improves readability by separating the information only used in reporting, as well as enables (simplified) storing/restoring of irqtrace_events snapshots. No functional change intended.

seqlock: lockdep assert non-preemptibility on seqcount_t write
Preemption must be disabled before entering a sequence count write side critical section. Failing to do so, the seqcount read side can preempt the write side section and spin for the entire scheduler tick. If that reader belongs to a real-time scheduling class, it can spin forever and the kernel will livelock. Assert through lockdep that preemption is disabled for seqcount writers.

lockdep: Add preemption enabled/disabled assertion APIs
Asserting that preemption is enabled or disabled is a critical sanity
check. Developers are usually reluctant to add such a check in a
fastpath as reading the preemption count can be costly.
Extend the lockdep API with macros asserting that preemption is disabled
or enabled. If lockdep is disabled, or if the underlying architecture
does not support kernel preemption, this assert has no runtime overhead.

seqlock: Implement raw_seqcount_begin() in terms of raw_read_seqcount()
raw_seqcount_begin() has the same code as raw_read_seqcount(), with the exception of masking the sequence counter's LSB before returning it to the caller. Note, raw_seqcount_begin() masks the counter's LSB before returning it to the caller so that read_seqcount_retry() can fail if the counter is odd -- without the overhead of an extra branching instruction.

seqlock: Add kernel-doc for seqcount_t and seqlock_t APIs

seqlock: Reorder seqcount_t and seqlock_t API definitions
The seqlock.h seqcount_t and seqlock_t API definitions are presented in
the chronological order of their development rather than the order that
makes most sense to readers. This makes it hard to follow and understand
the header file code.
Group and reorder all of the exported seqlock.h functions according to
their function.
First, group together the seqcount_t standard read path functions:
- __read_seqcount_begin()
- raw_read_seqcount_begin()
- read_seqcount_begin()
since each function is implemented exactly in terms of the one above
it. Then, group the special-case seqcount_t readers on their own as:
- raw_read_seqcount()
- raw_seqcount_begin()
since the only difference between the two functions is that the second
one masks the sequence counter LSB while the first one does not. Note
that raw_seqcount_begin() can actually be implemented in terms of
raw_read_seqcount(), which will be done in a follow-up commit.
Then, group the seqcount_t write path functions, instead of injecting
unrelated seqcount_t latch functions between them, and order them as:
- raw_write_seqcount_begin()
- raw_write_seqcount_end()
- write_seqcount_begin_nested()
- write_seqcount_begin()
- write_seqcount_end()
- raw_write_seqcount_barrier()
- write_seqcount_invalidate()
which is the expected natural order. This also isolates the seqcount_t
latch functions into their own area, at the end of the sequence counters
section, and before jumping to the next one: sequential locks
(seqlock_t).
Do a similar grouping and reordering for seqlock_t "locking" readers vs.
the "conditionally locking or lockless" ones.
No implementation code was changed in any of the reordering above.

seqlock: seqcount_t latch: End read sections with read_seqcount_retry()
The seqcount_t latch reader example at the raw_write_seqcount_latch() kernel-doc comment ends the latch read section with a manual smp memory barrier and sequence counter comparison. This is technically correct, but it is suboptimal: read_seqcount_retry() already contains the same logic of an smp memory barrier and sequence counter comparison. End the latch read critical section example with read_seqcount_retry(). Signed-off-by: Ahmed S.

Documentation: locking: Describe seqlock design and usage
Proper documentation for the design and usage of sequence counters and
sequential locks does not exist. Complete the seqlock.h documentation as
follows:
- Divide all documentation on a seqcount_t vs. seqlock_t basis. The
description for both mechanisms was intermingled, which is incorrect
since the usage constrains for each type are vastly different.
- Add an introductory paragraph describing the internal design of, and
rationale for, sequence counters.
- Document seqcount_t writer non-preemptibility requirement, which was
not previously documented anywhere, and provide a clear rationale.
- Provide template code for seqcount_t and seqlock_t initialization
and reader/writer critical sections.
- Recommend using seqlock_t by default. It implicitly handles the
serialization and non-preemptibility requirements of writers.
At seqlock.h:
- Remove references to brlocks as they've long been removed from the
kernel.
- Remove references to gcc-3.x since the kernel's minimum supported
gcc version is 4.9.

locking/qspinlock: Do not include atomic.h from qspinlock_types.h
This patch breaks a header loop involving qspinlock_types.h. The issue is that qspinlock_types.h includes atomic.h, which then eventually includes kernel.h which could lead back to the original file via spinlock_types.h. As ATOMIC_INIT is now defined by linux/types.h, there is no longer any need to include atomic.h from qspinlock_types.h. This also allows the CONFIG_PARAVIRT hack to be removed since it was trying to prevent exactly this loop.

lockdep: Move list.h inclusion into lockdep.h
Currently lockdep_types.h includes list.h without actually using any of its macros or functions. All it needs are the type definitions which were moved into types.h long ago. This potentially causes inclusion loops because both are included by many core header files. This patch moves the list.h inclusion into lockdep.h. Note that we could probably remove it completely but that could potentially result in compile failures should any end users not include list.h directly and also be unlucky enough to not get list.h via some other header file.

Third batch of perf tooling fixes for 5.8:
- Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI.
- Set opt->set in libsubcmd's OPT_CALLBACK_SET(). Fixes
'perf record --switch-output-event event-name' usage.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
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.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

A pile of fixes for x86:
- Fix the I/O bitmap invalidation on XEN PV, which was overlooked in the
recent ioperm/iopl rework. This caused the TSS and XEN's I/O bitmap to
get out of sync.
- Use the proper vectors for HYPERV.
- Make disabling of stack protector for the entry code work with GCC
builds which enable stack protector by default. Removing the option is
not sufficient, it needs an explicit -fno-stack-protector to shut it
off.
- Mark check_user_regs() noinstr as it is called from noinstr code. The
missing annotation causes it to be placed in the text section which
makes it instrumentable.
- Add the missing interrupt disable in exc_alignment_check()
- Fixup a XEN_PV build dependency in the 32bit entry code
- A few fixes to make the Clang integrated assembler happy
- Move EFI stub build to the right place for out of tree builds
- Make prepare_exit_to_usermode() static. It's not longer called from ASM
code.

Two fixes for the timer wheel:
- A timer which is already expired at enqueue time can set the
base->next_expiry value backwards. As a consequence base->clk can be set
back as well. This can lead to timers expiring early. Add a sanity check
to prevent this.
- When a timer is queued with an expiry time beyond the wheel capacity
then it should be queued in the bucket of the last wheel level which is
expiring last. The code adjusts expiry time to the maximum wheel
capacity, which is only correct when the wheel clock is 0. Aside of that
the check whether the delta is larger than wheel capacity does not check
the delta, it checks the expiry value itself. As a result timers can
expire at random.
Fix this by checking the right variable and adjust expiry time so it
becomes base->clock plus capacity which places it into the outmost
bucket in the last wheel level.

A set of scheduler fixes:
- Plug a load average accounting race which was introduced with a recent
optimization casing load average to show bogus numbers.
- Fix the rseq CPU id initialization for new tasks. sched_fork() does not
update the rseq CPU id so the id is the stale id of the parent task,
which can cause user space data corruption.
- Handle a 0 return value of task_h_load() correctly in the load balancer,
which does not decrease imbalance and therefore pulls until the maximum
number of loops is reached, which might be all tasks just created by a
fork bomb.

Two fixes for the interrupt subsystem:
- Make the handling of the firmware node consistent and do not free the
node after the domain has been created successfully. The core code
stores a pointer to it which can lead to a use after free or double
free.
This used to "work" because the pointer was not stored when the initial
code was written, but at some point later it was required to store
it. Of course nobody noticed that the existing users break that way.
- Handle affinity setting on inactive interrupts correctly when
hierarchical irq domains are enabled. When interrupts are inactive with
the modern hierarchical irqdomain design, the interrupt chips are not
necessarily in a state where affinity changes can be handled. The legacy
irq chip design allowed this because interrupts are immediately fully
initialized at allocation time. X86 has a hacky workaround for this, but
other implementations do not. This cased malfunction on GIC-V3. Instead
of playing whack a mole to find all affected drivers, change the core
code to store the requested affinity setting and then establish it when
the interrupt is allocated, which makes the X86 hack go away.

x86/boot: Don't add the EFI stub to targets
vmlinux-objs-y is added to targets, which currently means that the EFI
stub gets added to the targets as well. It shouldn't be added since it
is built elsewhere.
This confuses Makefile.build which interprets the EFI stub as a target
$(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a
and will create drivers/firmware/efi/libstub/ underneath
arch/x86/boot/compressed, to hold this supposed target, if building
out-of-tree. [0]
Fix this by pulling the stub out of vmlinux-objs-y into efi-obj-y.
[0] See scripts/Makefile.build near the end:

x86/entry: Actually disable stack protector
Some builds of GCC enable stack protector by default. Simply removing
the arguments is not sufficient to disable stack protector, as the stack
protector for those GCC builds must be explicitly disabled. Remove the
argument removals and add -fno-stack-protector. Additionally include
missed x32 argument updates, and adjust whitespace for readability.

hwmon: (drivetemp) Avoid SCT usage on Toshiba DT01ACA family drives
It has been observed that Toshiba DT01ACA family drives have
WRITE FPDMA QUEUED command timeouts and sometimes just freeze until
power-cycled under heavy write loads when their temperature is getting
polled in SCT mode. The SMART mode seems to be fine, though.
Let's make sure we don't use SCT mode for these drives then.
While only the 3 TB model was actually caught exhibiting the problem let's
play safe here to avoid data corruption and extend the ban to the whole
family.

genirq/affinity: Handle affinity setting on inactive interrupts correctly
Setting interrupt affinity on inactive interrupts is inconsistent when
hierarchical irq domains are enabled. The core code should just store the
affinity and not call into the irq chip driver for inactive interrupts
because the chip drivers may not be in a state to handle such requests.
X86 has a hacky workaround for that but all other irq chips have not which
causes problems e.g. on GIC V3 ITS.
Instead of adding more ugly hacks all over the place, solve the problem in
the core code. If the affinity is set on an inactive interrupt then:
- Store it in the irq descriptors affinity mask
- Update the effective affinity to reflect that so user space has
a consistent view
- Don't call into the irq chip driver
This is the core equivalent of the X86 workaround and works correctly
because the affinity setting is established in the irq chip when the
interrupt is activated later on.
Note, that this is only effective when hierarchical irq domains are enabled
by the architecture. Doing it unconditionally would break legacy irq chip
implementations.
For hierarchial irq domains this works correctly as none of the drivers can
have a dependency on affinity setting in inactive state by design.
Remove the X86 workaround as it is not longer required.

timer: Fix wheel index calculation on last level
When an expiration delta falls into the last level of the wheel, that delta
has be compared against the maximum possible delay and reduced to fit in if
necessary.
However instead of comparing the delta against the maximum, the code
compares the actual expiry against the maximum. Then instead of fixing the
delta to fit in, it sets the maximum delta as the expiry value.
This can result in various undesired outcomes, the worst possible one
being a timer expiring 15 days ahead to fire immediately.

regulator: Fixes for v5.8
The more substantial fix here is the rename of the da903x driver which fixes a collision with the parent MFD driver name which caused issues when things were built as modules. There's also a fix for a mislableled regulator on the pmi8994 which is quite important for systems with that device. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl8RmrkTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0ANIB/43sHA61bYPIeyJ+TUKWTAaoEf4AluO I0lyo4AsnquLXD4/4gJi4d+rVBL7HF/Kyguq2y90VabtfuhddSb3B6PqLgr9+Ja8 F/4iDGUjiMN3v3fCfkyLlYoou7KChJlWV0OQAsZ+W4KqX5l5qD4R+2pamx0RRzXJ 2MYiRYQ98Ez/0eNaHe+rSOfBGpadYj8AfnwZFLHR5AAybZEMRo8lYd7oLdwCkpW/ 0ySgDjGWxzQKwhg7GBvrMxgaq4zHqfgOh34mfUBrbgF3SqD4UduSQ2iU12HepV1a w/No5YS+BcZoR6djEpK4T1SmHdy7C6HnOhiFzn3jBczMptxB+8Ae3yMZ =SXtn -----END PGP SIGNATURE----- Merge tag 'regulator-fix-v5.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into master Pull regulator fixes from Mark Brown: "The more substantial fix here is the rename of the da903x driver which fixes a collision with the parent MFD driver name which caused issues when things were built as modules.

RISC-V: Upgrade smp_mb__after_spinlock() to iorw,iorw
While digging through the recent mmiowb preemption issue it came up that we aren't actually preventing IO from crossing a scheduling boundary. While it's a bit ugly to overload smp_mb__after_spinlock() with this behavior, it's what PowerPC is doing so there's some precedent. Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com> |
