netfilter: nft_set_hash: skip duplicated elements pending gc run
rhashtable does not provide stable walk, duplicated elements are
possible in case of resizing. I considered that checking for errors when
calling rhashtable_walk_next() was sufficient to detect the resizing.
However, rhashtable_walk_next() returns -EAGAIN only at the end of the
iteration, which is too late, because a gc work containing duplicated
elements could have been already scheduled for removal to the worker.
Add a u32 gc worker sequence number per set, bump it on every workqueue
run. Annotate gc worker sequence number on the expired element. Use it
to skip those already seen in this gc workqueue run.
Note that this new field is never reset in case gc transaction fails, so
next gc worker run on the expired element overrides it. Wraparound of gc
worker sequence number should not be an issue with stale gc worker
sequence number in the element, that would just postpone the element
removal in one gc run.
Note that it is not possible to use flags to annotate that element is
pending gc run to detect duplicates, given that gc transaction can be
invalidated in case of update from the control plane, therefore, not
allowing to clear such flag.
On x86_64, pahole reports no changes in the size of nft_rhash_elem.

ipvs: fix UB due to uninitialized stack access in ip_vs_protocol_init()
Under certain kernel configurations when building with Clang/LLVM, the
compiler does not generate a return or jump as the terminator
instruction for ip_vs_protocol_init(), triggering the following objtool
warning during build time:
vmlinux.o: warning: objtool: ip_vs_protocol_init() falls through to next function __initstub__kmod_ip_vs_rr__935_123_ip_vs_rr_init6()
At runtime, this either causes an oops when trying to load the ipvs
module or a boot-time panic if ipvs is built-in. This same issue has
been reported by the Intel kernel test robot previously.
Digging deeper into both LLVM and the kernel code reveals this to be a
undefined behavior problem. ip_vs_protocol_init() uses a on-stack buffer
of 64 chars to store the registered protocol names and leaves it
uninitialized after definition. The function calls strnlen() when
concatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCE
strnlen() performs an extra step to check whether the last byte of the
input char buffer is a null character (commit 3009f891bb9f ("fortify:
Allow strlen() and strnlen() to pass compile-time known lengths")).
This, together with possibly other configurations, cause the following
IR to be generated:
The above code calculates the address of the last char in the buffer
(value %15) and then loads from it (value %16). Because the buffer is
never initialized, the LLVM GVN pass marks value %16 as undefined:
This gives later passes (SCCP, in particular) more DCE opportunities by
propagating the undef value further, and eventually removes everything
after the load on the uninitialized stack location:
In this way, the generated native code will just fall through to the
next function, as LLVM does not generate any code for the unreachable IR
instruction and leaves the function without a terminator.
Zero the on-stack buffer to avoid this possible UB.

Replacing the qdisc with pfifo makes retransmissions go away.
It appears that a flow may have a delayed packet with a very near
Tx time. Later, we may get busy processing Rx and the target Tx time
will pass, but we won't service Tx since the CPU is busy with Rx.
If Rx sees an ACK and we try to push more data for the delayed flow
we may fastpath the skb, not realizing that there are already "ready
to send" packets for this flow sitting in the qdisc.
Don't trust the fastpath if we are "behind" according to the projected

within the offload window to be okay for fastpath we must consider
the entire offload window as "now".

When phy_ethtool_set_eee_noneg() detects a change in the LPI
parameters, it attempts to update phylib state and trigger the link
to cycle so the MAC sees the updated parameters.
However, in doing so, it sets phydev->enable_tx_lpi depending on
whether the EEE configuration allows the MAC to generate LPI without
taking into account the result of negotiation.
This can be demonstrated with a 1000base-T FD interface by:
# ethtool --set-eee eno0 advertise 8 # cause EEE to be not negotiated
# ethtool --set-eee eno0 tx-lpi off
# ethtool --set-eee eno0 tx-lpi on
This results in being true, despite EEE not having been negotiated and:
# ethtool --show-eee eno0
EEE status: enabled - inactive

Supported EEE link modes: 100baseT/Full
1000baseT/Full
Advertised EEE link modes: 100baseT/Full
1000baseT/Full
Fix this by keeping track of whether EEE was negotiated via a new
eee_active member in struct phy_device, and include this state in
the decision whether phydev->enable_tx_lpi should be set.

RFC8981 section 3.4 says that existing temporary addresses must have their

strongly imply in Linux's case that if the "mngtmpaddr" address is deleted or

right away.
But now the temporary address is renewed even after ‘mngtmpaddr’ is removed

failed to remove the addresses. Fix this by deleting the temporary address

s390/iucv: MSG_PEEK causes memory leak in iucv_sock_destruct()
Passing MSG_PEEK flag to skb_recv_datagram() increments skb refcount
(skb->users) and iucv_sock_recvmsg() does not decrement skb refcount
at exit.
This results in skb memory leak in skb_queue_purge() and WARN_ON in
iucv_sock_destruct() during socket close. To fix this decrease
skb refcount by one if MSG_PEEK is set in order to prevent memory
leak and WARN_ON.
By forcing memory allocation failures in idr_alloc_32, syzbot is able
to provoke a condition where idr_is_empty returns false despite there
being no items in the IDR. This turns out to be because the radix tree
of the IDR contains only internal radix-tree nodes and it is this that
causes idr_is_empty to return false. The internal nodes are cleaned by
idr_destroy.
Use idr_for_each to check that the IDR is empty instead of
idr_is_empty to avoid the problem.

Commit under fixes extended extack reporting to dumps.
It works under normal conditions, because extack errors are

it's quite rare that the dump starts okay but fails later.
If the dump does fail later, however, the input skb will
already have the initiating message pulled, so checking
if bad attr falls within skb->data will fail.
Switch the check to using nlh, which is always valid.
syzbot found a way to hit that scenario by filling up

tg3: Set coherent DMA mask bits to 31 for BCM57766 chipsets
The hardware on Broadcom 1G chipsets have a known limitation
where they cannot handle DMA addresses that cross over 4GB.
When such an address is encountered, the hardware sets the
address overflow error bit in the DMA status register and
triggers a reset.
However, BCM57766 hardware is setting the overflow bit and
triggering a reset in some cases when there is no actual
underlying address overflow. The hardware team analyzed the
issue and concluded that it is happening when the status
block update has an address with higher (b16 to b31) bits
as 0xffff following a previous update that had lowest bits
as 0xffff.
To work around this bug in the BCM57766 hardware, set the
coherent dma mask from the current 64b to 31b. This will
ensure that upper bits of the status block DMA address are
always at most 0x7fff, thus avoiding the improper overflow
check described above. This work around is intended for only
status block and ring memories and has no effect on TX and
RX buffers as they do not require coherent memory.

"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core:
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code:
- Add small file operations for debugfs, to reduce the struct ops
size.
- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.
Netfilter:
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.
BPF:
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state
lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per
device neigh lists.
Driver API:
- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling:
- forwarding: introduce deferred commands, to simplify the cleanup
phase
Drivers:
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

LLCC and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip sparx5

Pull SoC devicetree updates from Arnd Bergmann:
"This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device
driver and platform code has already made it in. This is likely the
last ARMv5 (!) platform to ever get added, updating the 20+ year
old at91/sam9 platform with DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number
of A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in
older Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely
related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end
laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and
Tablet chips, still using the older ARMv8.0 cores from
RK3328/RK3399 but with a newer process and other improvements from
the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also
added, these are just lower-cost versions of their normal
counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly
added chips above, notably all the Apple phones and tablets. The other
new machines include nine industrial/embedded boards with NXP i.MX6 or
i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for
Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm
qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.

Pull gpio updates from Bartosz Golaszewski:
"Three new drivers, support for some new models in existing ones and
lots of various tweaks and improvements across the board (switching to
using recommended APIs, code shrink and simplification, etc.).
Also a new feature in the character device uAPI where we now notify
the user-space about changes triggered by in-kernel users as well, not
only when they were done by other user-space agents.
Summary:
GPIOLIB core:
- use the new mem_is_zero() instead of memchr_inv(s, 0, n)
- don't store debounce period twice needlessly
- clean-up debugfs handling
- remove leftover comments referring to no longer used spinlocks
- unduplicate some operations like SRCU locks and initializing GPIO
descriptors
- constify the sysfs class struct
- use lock guards in GPIO sysfs code
- update GPIO uAPI internal flags all at once atomically for
consistency with other places
- modify the behavior of the sysfs interface by no longer exporting
lines that are named inside the driver code or board files with the
sysfs links bearing the line names as this has for many years been
largely unused due to the prevalence of DT, ACPI and firmware nodes
over board files and made the API inconsistent
- for GPIO interrupt providers: free irqs that are still requested by
users when removing the chip
GPIO uAPI:
- notify user-space about changes to GPIO lines' state (requested,
released, reconfigured) triggered from the kernel as well (until
now we'd only do this for changes triggered from user-space)
- to that end: modify the internal workings of the notification
mechanism by switching to an atomic notifier which allows us to
send events from atomic context
- also to that end store the debounce period in the GPIO descriptor
struct and not in the character device context struct
- while at it, also cover the corner-case of users introducing
changes over sysfs while others watch them via the character device
- don't report GPIO lines requested as interrupts as "used" to
user-space as it can still request them as GPIOs
New drivers:
- GPIO part of the MFD Congatec Board Controller
- PolarFire GPIO controller
- GPIOs on FTDI FT2232H
Driver improvements:
- use generic device property accessors instead of OF-specific ones
across many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci,
ts4900, xilinx, mvebu)
- use devres helpers to simplify error paths and either shrink or
entirely remove the driver's remove() callback (grgpio, amdpt,
menz127, max730x, ftgpio010, 74x164, ljca)
- use helper variables to store the address of pdev->dev and avoid
some line-breaks
- use device_for_each_child_node_scoped() to avoid having to put the
fwnode on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
- use a scoped bitmap to simplify the code and drop goto labels in
gpio-aggregator
- drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby,
xilinx)
- add support for new models to gpio-aspeed, gpio-rockchip and
gpio-dwapb
- clean-up ACPI handling and some other bits in gpio-xgene-sb
- replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
- allow to build davinci and mvebu drivers with COMPILE_TEST=y
- remove dead code in gpio-mb86s7x
- switch back to using platform_driver::remove() (after the
conversion to remove_new()) across the GPIO drivers
- remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop
this deprecated symbol
- convert the gpio-altera driver to no longer pull in the deprecated
legacy-of-mm-gpiochip.h header
- use of_property_present() instead of of_property_read_bool() in
gpiolib-of and gpio-rockchip
- allow to build the tegra186 driver on Tegra234 platforms in Kconfig
Late fixes:
- add a missing return value check after devm_kasprintf() to
gpio-grgpio
DT bindings:
- document the ngpios property of gpio-mmio
- add support for a new aspeed model
- fix the example for st,nomadik-gpio

- fix typos in TODO
- reorder headers alphabetically in some drivers

Pull ftrace updates from Steven Rostedt:
- Restructure the function graph shadow stack to prepare it for use
with kretprobes
With the goal of merging the shadow stack logic of function graph and
kretprobes, some more restructuring of the function shadow stack is
required.
Move out function graph specific fields from the fgraph
infrastructure and store it on the new stack variables that can pass
data from the entry callback to the exit callback.
Hopefully, with this change, the merge of kretprobes to use fgraph
shadow stacks will be ready by the next merge window.
- Make shadow stack 4k instead of using PAGE_SIZE.
Some architectures have very large PAGE_SIZE values which make its
use for shadow stacks waste a lot of memory.
- Give shadow stacks its own kmem cache.
When function graph is started, every task on the system gets a
shadow stack. In the future, shadow stacks may not be 4K in size.
Have it have its own kmem cache so that whatever size it becomes will
still be efficient in allocations.
- Initialize profiler graph ops as it will be needed for new updates to
fgraph
- Convert to use guard(mutex) for several ftrace and fgraph functions
- Add more comments and documentation
- Show function return address in function graph tracer
Add an option to show the caller of a function at each entry of the
function graph tracer, similar to what the function tracer does.
- Abstract out ftrace_regs from being used directly like pt_regs
ftrace_regs was created to store a partial pt_regs. It holds only the
registers and stack information to get to the function arguments and
return values. On several archs, it is simply a wrapper around
pt_regs. But some users would access ftrace_regs directly to get the
pt_regs which will not work on all archs. Make ftrace_regs an
abstract structure that requires all access to its fields be through
accessor functions.
- Show how long it takes to do function code modifications
When code modification for function hooks happen, it always had the
time recorded in how long it took to do the conversion. But this
value was never exported. Recently the code was touched due to new
ROX modification handling that caused a large slow down in doing the
modifications and had a significant impact on boot times.
Expose the timings in the dyn_ftrace_total_info file. This file was
created a while ago to show information about memory usage and such
to implement dynamic function tracing. It's also an appropriate file
to store the timings of this modification as well. This will make it
easier to see the impact of changes to code modification on boot up
timings.

Pull sched_ext updates from Tejun Heo:
- Improve the default select_cpu() implementation making it topology
aware and handle WAKE_SYNC better.
- set_arg_maybe_null() was used to inform the verifier which ops args
could be NULL in a rather hackish way. Use the new __nullable CFI
stub tags instead.
- On Sapphire Rapids multi-socket systems, a BPF scheduler, by
hammering on the same queue across sockets, could live-lock the
system to the point where the system couldn't make reasonable forward
progress.
This could lead to soft-lockup triggered resets or stalling out
bypass mode switch and thus BPF scheduler ejection for tens of
minutes if not hours. After trying a number of mitigations, the
following set worked reliably:
- Injecting artificial cpu_relax() loops in two places while
sched_ext is trying to turn on the bypass mode.
- Triggering scheduler ejection when soft-lockup detection is
imminent (a quarter of threshold left).
While not the prettiest, the impact both in terms of code complexity
and overhead is minimal.
- A common complaint on the API is the overuse of the word "dispatch"
and the confusion around "consume". This is due to how the dispatch
queues became more generic over time. Rename the affected kfuncs for
clarity. Thanks to BPF's compatibility features, this change can be
made in a way that's both forward and backward compatible. The
compatibility code will be dropped in a few releases.

Pull workqueue updates from Tejun Heo:
- The maximum concurrency limit of 512 which was set a long time ago is
too low now.
A legitimate use (BPF cgroup release) of system_wq could saturate it
under stress test conditions leading to false dependencies and
deadlocks.
While the offending use was switched to a dedicated workqueue, use
the opportunity to bump WQ_MAX_ACTIVE four fold and document that
system workqueue shouldn't be saturated. Workqueue should add at
least a warning mechanism for cases where system workqueues are
saturated.
- Recent workqueue updates to support more flexible execution topology
made unbound workqueues use per-cpu worker pool frontends which
pushed up workqueue flush overhead.
As consecutive CPUs are likely to be pointing to the same worker
pool, reduce overhead by switching locks only when necessary.

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"

Pull vdso data page handling updates from Thomas Gleixner:
"First steps of consolidating the VDSO data page handling.
The VDSO data page handling is architecture specific for historical
reasons, but there is no real technical reason to do so.
Aside of that VDSO data has become a dump ground for various
mechanisms and fail to provide a clear separation of the
functionalities.
Clean this up by:
- consolidating the VDSO page data by getting rid of architecture
specific warts especially in x86 and PowerPC.
- removing the last includes of header files which are pulling in
other headers outside of the VDSO namespace.
- seperating timekeeping and other VDSO data accordingly.
Further consolidation of the VDSO page handling is done in subsequent
changes scheduled for the next merge window.
This also lays the ground for expanding the VDSO time getters for
independent PTP clocks in a generic way without making every
architecture add support seperately"

Pull interrupt subsystem updates from Thomas Gleixner:
"Tree wide:
- Make nr_irqs static to the core code and provide accessor functions
to remove existing and prevent future aliasing problems with local
variables or function arguments of the same name.
Core code:
- Prevent freeing an interrupt in the devres code which is not
managed by devres in the first place.
- Use seq_put_decimal_ull_width() for decimal values output in
/proc/interrupts which increases performance significantly as it
avoids parsing the format strings over and over.
- Optimize raising the timer and hrtimer soft interrupts by using the
'set bit only' variants instead of the combined version which
checks whether ksoftirqd should be woken up. The latter is a
pointless exercise as both soft interrupts are raised in the
context of the timer interrupt and therefore never wake up
ksoftirqd.
- Delegate timer/hrtimer soft interrupt processing to a dedicated
thread on RT.
Timer and hrtimer soft interrupts are always processed in ksoftirqd
on RT enabled kernels. This can lead to high latencies when other
soft interrupts are delegated to ksoftirqd as well.
The separate thread allows to run them seperately under a RT
scheduling policy to reduce the latency overhead.
Drivers:
- New drivers or extensions of existing drivers to support Renesas
RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
chips
- Support for multi-cluster GICs on MIPS.
MIPS CPUs can come with multiple CPU clusters, where each CPU
cluster has its own GIC (Generic Interrupt Controller). This
requires to access the GIC of a remote cluster through a redirect
register block.
This is encapsulated into a set of helper functions to keep the
complexity out of the actual code paths which handle the GIC
details.
- Support for encrypted guests in the ARM GICV3 ITS driver
The ITS page needs to be shared with the hypervisor and therefore
must be decrypted.
- Small cleanups and fixes all over the place"
