Merge tag 'timers-core-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:

- The final step to get rid of auto-rearming posix-timers

posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.

This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.

Cure this by:

- Embedding the sigqueue into the timer struct to have the same
life time rules. Aside of that this also avoids the lookup of
the timer in the signal delivery and rearm path as it's just a
always valid container_of() now.

- Queuing ignored timer signals onto a seperate ignored list.

- Moving queued timer signals onto the ignored list when the
signal is switched to SIG_IGN before it could be delivered.

- Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal
delivery code to rearm the timer.

This also required to consolidate the signal delivery rules so they
are consistent across all situations. With that all self test
scenarios finally succeed.

- Core infrastructure for VFS multigrain timestamping

This is required to allow the kernel to use coarse grained time
stamps by default and switch to fine grained time stamps when inode
attributes are actively observed via getattr().

These changes have been provided to the VFS tree as well, so that
the VFS specific infrastructure could be built on top.

- Cleanup and consolidation of the sleep() infrastructure

- Move all sleep and timeout functions into one file

- Rework udelay() and ndelay() into proper documented inline
functions and replace the hardcoded magic numbers by proper
defines.

- Rework the fsleep() implementation to take the reality of the
timer wheel granularity on different HZ values into account.
Right now the boundaries are hard coded time ranges which fail
to provide the requested accuracy on different HZ settings.

- Update documentation for all sleep/timeout related functions
and fix up stale documentation links all over the place

- Fixup a few usage sites

- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
clocks

A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as
that's the clock which drives the timekeeping adjustments via the
various user space daemons through adjtimex(2).

The non TAI based clock domains are accessible via the file
descriptor based posix clocks, but their usability is very limited.
They can't be accessed fast as they always go all the way out to
the hardware and they cannot be utilized in the kernel itself.

As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.

The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the
kernel provides access to clock MONOTONIC, REALTIME etc.

Instead of creating a duplicated infrastructure this rework
converts timekeeping and adjtimex(2) into generic functionality
which operates on pointers to data structures instead of using
static variables.

This allows to provide time accessors and adjtimex(2) functionality
for the independent PTP clocks in a subsequent step.

- Consolidate hrtimer initialization

hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.

That's an extra unnecessary step and makes Rust support less
straight forward than it should be.

Provide a new set of hrtimer_setup*() functions and convert the
core code and a few usage sites of the less frequently used
interfaces over.

The bulk of the htimer_init() to hrtimer_setup() conversion is
already prepared and scheduled for the next merge window.

- Drivers:

- Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.

Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with
other clusters.

- Mostly boring cleanups, fixes, improvements and code movement"

timekeeping: Always check for negative motion

clocksource_delta() has two variants. One with a check for negative motion,
which is only selected by x86. This is a historic leftover as this function
was previously used in the time getter hot paths.

Since 135225a363ae timekeeping_cycles_to_ns() has unconditional protection
against this as a by-product of the protection against 64bit math overflow.

clocksource_delta() is only used in the clocksource watchdog and in
timekeeping_advance(). The extra conditional there is not hurting anyone.

Remove the config option and unconditionally prevent negative motion of the
readout.

Merge tag 'timers-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timers and timekeeping updates from Thomas Gleixner:
"Core code:

- Make timekeeping and VDSO time readouts resilent against math
overflow:

In guest context the kernel is prone to math overflow when the host
defers the timer interrupt due to overload, malfunction or malice.

This can be mitigated by checking the clocksource delta for the
maximum deferrement which is readily available. If that value is
exceeded then the code uses a slowpath function which can handle
the multiplication overflow.

This functionality is enabled unconditionally in the kernel, but
made conditional in the VDSO code. The latter is conditional
because it allows architectures to optimize the check so it is not
causing performance regressions.

On X86 this is achieved by reworking the existing check for
negative TSC deltas as a negative delta obviously exceeds the
maximum deferrement when it is evaluated as an unsigned value. That
avoids two conditionals in the hotpath and allows to hide both the
negative delta and the large delta handling in the same slow path.

- Add an initial minimal ktime_t abstraction for Rust

- The usual boring cleanups and enhancements

Drivers:

- Boring updates to device trees and trivial enhancements in various
drivers"
