selftest: tcp: Move expected_errno into each test case in bind_wildcard.c.
This is a preparation patch for the following patch. Let's define expected_errno in each test case so that we can add other test cases easily. Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

selftest: tcp: Fix address length in bind_wildcard.c.
The selftest passes the IPv6 address length for an IPv4 address.
We should pass the correct length.
Note inet_bind_sk() does not check if the size is larger than
sizeof(struct sockaddr_in), so there is no real bug in this
selftest.
Fixes:

selftests/net: Improve bind_bhash.sh to accommodate predictable network interface names
Starting with v197, systemd uses predictable interface network names, the traditional interface naming scheme (eth0) is deprecated, therefore it cannot be assumed that the eth0 interface exists on the host. This modification makes the bind_bhash test program run in a separate network namespace and no longer needs to consider the name of the network interface on the host.

ARM:
* Clean up vCPU targets, always returning generic v8 as the preferred target
* Trap forwarding infrastructure for nested virtualization (used for traps
that are taken from an L2 guest and are needed by the L1 hypervisor)
* FEAT_TLBIRANGE support to only invalidate specific ranges of addresses
when collapsing a table PTE to a block PTE. This avoids that the guest
refills the TLBs again for addresses that aren't covered by the table PTE.
* Fix vPMU issues related to handling of PMUver.
* Don't unnecessary align non-stack allocations in the EL2 VA space
* Drop HCR_VIRT_EXCP_MASK, which was never used...
* Don't use smp_processor_id() in kvm_arch_vcpu_load(),
but the cpu parameter instead
* Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
* Remove prototypes without implementations
RISC-V:
* Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
* Added ONE_REG interface for SATP mode
* Added ONE_REG interface to enable/disable multiple ISA extensions
* Improved error codes returned by ONE_REG interfaces
* Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
* Added get-reg-list selftest for KVM RISC-V
s390:
* PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
* Guest debug fixes (Ilya)
x86:
* Clean up KVM's handling of Intel architectural events
* Intel bugfixes
* Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug
registers and generate/handle #DBs
* Clean up LBR virtualization code
* Fix a bug where KVM fails to set the target pCPU during an IRTE update
* Fix fatal bugs in SEV-ES intrahost migration
* Fix a bug where the recent (architecturally correct) change to reinject
#BP and skip INT3 broke SEV guests (can't decode INT3 to skip it)
* Retry APIC map recalculation if a vCPU is added/enabled
* Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
"emergency disabling" behavior to KVM actually being loaded, and move all of
the logic within KVM
* Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
ratio MSR cannot diverge from the default when TSC scaling is disabled
up related code
* Add a framework to allow "caching" feature flags so that KVM can check if
the guest can use a feature without needing to search guest CPUID
* Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
* Fix KVM's handling of !visible guest roots to avoid premature triple fault
injection
* Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
that is needed by external users (currently only KVMGT), and fix a variety
of issues in the process
This last item had a silly one-character bug in the topic branch that
was sent to me. Because it caused pretty bad selftest failures in
some configurations, I decided to squash in the fix. So, while the
exact commit ids haven't been in linux-next, the code has (from the
kvm-x86 tree).
Generic:
* Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
action specific data without needing to constantly update the main handlers.
* Drop unused function declarations
Selftests:
* Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
* Add support for printf() in guest code and covert all guest asserts to use
printf-based reporting
* Clean up the PMU event filter test and add new testcases
* Include x86 selftests in the KVM x86 MAINTAINERS entry

Probes updates for v6.6:
- kprobes: use struct_size() for variable size kretprobe_instance
data structure.
- eprobe: Simplify trace_eprobe list iteration.
- probe events: Data structure field access support on BTF argument.
. Update BTF argument support on the functions in the kernel loadable
modules (only loaded modules are supported).
. Move generic BTF access function (search function prototype and get
function parameters) to a separated file.
. Add a function to search a member of data structure in BTF.
. Support accessing BTF data structure member from probe args by
C-like arrow('->') and dot('.') operators. e.g.
't sched_switch next=next->pid vruntime=next->se.vruntime'
. Support accessing BTF data structure member from $retval. e.g.
'f getname_flags%return +0($retval->name):string'
. Add string type checking if BTF type info is available.
This will reject if user specify ":string" type for non "char
pointer" type.
. Automatically assume the fprobe event as a function return event
if $retval is used.
- selftests/ftrace: Add BTF data field access test cases.
- Documentation: Update fprobe event example with BTF data field.

- Support accessing BTF data structure member from probe args by
C-like arrow('->') and dot('.') operators. e.g.
't sched_switch next=next->pid vruntime=next->se.vruntime'
- Support accessing BTF data structure member from $retval. e.g.
'f getname_flags%return +0($retval->name):string'
- Add string type checking if BTF type info is available. This will
reject if user specify ":string" type for non "char pointer"
type.
- Automatically assume the fprobe event as a function return event
if $retval is used.
- selftests/ftrace: Add BTF data field access test cases.

Fix __NR_map_shadow_stack syscall-renumbering fallout in the
x86 self-test code.
[ Arguably the existing code was unnecessarily fragile, and
tooling should have picked up the new syscall number,
and a wider fix is being worked on - but meanwhile, let's
not have the old syscall number in the kernel tree. ]

Tracing updates for 6.6:
User visible changes:
- Added a way to easier filter with cpumasks:
# echo 'cpumask & CPUS{17-42}' > /sys/kernel/tracing/events/ipi_send_cpumask/filter
- Show actual size of ring buffer after modifying the ring buffer size via
buffer_size_kb. Currently it just returns what was written, but the actual
size rounds up to the sub buffer size. Show that real size instead.
Major changes:
- Added "eventfs". This is the code that handles the inodes and dentries of
tracefs/events directory. As there are thousands of events, and each event
has several inodes and dentries that currently exist even when tracing is
never used, they take up precious memory. Instead, eventfs will allocate
the inodes and dentries in a JIT way (similar to what procfs does). There
is now metadata that handles the events and subdirectories, and will create
the inodes and dentries when they are used.
Note, I also have patches that remove the subdirectory meta data, but will
wait till the next merge window before applying them. It's a little more
complex, and I want to make sure the dynamic code works properly before
adding more complexity, making it easier to revert if need be.
Minor changes:
- Optimization to user event list traversal.
- Remove intermediate permission of tracefs files (note the intermediate
permission removes all access to the files so it is not a security concern,
but just a clean up.)
- Add the complex fix to FORTIFY_SOURCE to the kernel stack event logic.
- Other minor clean ups.

workqueue: Changes for v6.6
* Unbound workqueues now support more flexible affinity scopes. The default behavior is to soft-affine according to last level cache boundaries. A work item queued from a given LLC is executed by a worker running on the same LLC but the worker may be moved across cache boundaries as the scheduler sees fit. On machines which multiple L3 caches, which are becoming more popular along with chiplet designs, this improves cache locality while not harming work conservation too much. Unbound workqueues are now also a lot more flexible in terms of execution affinity. Differeing levels of affinity scopes are supported and both the default and per-workqueue affinity settings can be modified dynamically. This should help working around amny of sub-optimal behaviors observed recently with asymmetric ARM CPUs. This involved signficant restructuring of workqueue code. Nothing was reported yet but there's some risk of subtle regressions. Should keep an eye out. * Rescuer workers now has more identifiable comms. * workqueue.unbound_cpus added so that CPUs which can be used by workqueue can be constrained early during boot. * Now that all the in-tree users have been flushed out, trigger warning if system-wide workqueues are flushed. * One pull commit from for-6.5-fixes to avoid cascading conflicts in the affinity scope patchset. -----BEGIN PGP SIGNATURE----- iIQEABYIACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZPERlQ4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGVqQAPwIOy9tWY5jFAmMuIyH6wV50hbmfxCc2n5xhQNr 5HoyGgEA8lw1W7afDCIPiQVA7AYsu8dhwuNSOcRCJxhrrn4XsA0= =g/Uu -----END PGP SIGNATURE----- Merge tag 'wq-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue updates from Tejun Heo: - Unbound workqueues now support more flexible affinity scopes.

* cpuset received some cleanups and prepatory patches for the pending
cpus.exclusive patchset which will allow cpuset partitions to be created
below non-partition parents, which should ease the management of partition
cpusets.

selftests/x86: Update map_shadow_stack syscall nr
Shadow stack's selftest utilizes the map_shadow_stack syscall. The
syscall is new with the feature, but the selftests cannot automatically
find the headers for the kernel source tree they are located in. This
resulted in the shadow stack test failing to build until the brand new
headers were installed.
To avoid this, a copy of the new uapi defines needed by the test were
included in the selftest (see link for discussion). When shadow stack was
merged the syscall number was changed, but the copy in the selftest was
not updated.
So update the copy of the syscall number define used when the required
headers are not installed, to have the final syscall number from the
merge.

selftests: fib_tests: Add multipath list receive tests
The test uses perf stat to count the number of fib:fib_table_lookup tracepoint hits for IPv4 and the number of fib6:fib6_table_lookup for IPv6. The measured count is checked to be within 5% of the total number of packets sent via veth1. Signed-off-by: Sriram Yagnaraman <sriram.yagnaraman@est.tech> Signed-off-by: David S.

powerpc updates for 6.6
- Add HOTPLUG_SMT support (/sys/devices/system/cpu/smt) and honour the
configured SMT state when hotplugging CPUs into the system.
- Combine final TLB flush and lazy TLB mm shootdown IPIs when using the Radix
MMU to avoid a broadcast TLBIE flush on exit.
- Drop the exclusion between ptrace/perf watchpoints, and drop the now unused
associated arch hooks.
- Add support for the "nohlt" command line option to disable CPU idle.
- Add support for -fpatchable-function-entry for ftrace, with GCC >= 13.1.
- Rework memory block size determination, and support 256MB size on systems
with GPUs that have hotpluggable memory.
- Various other small features and fixes.

CET consists of two related security features: shadow stacks and indirect branch tracking. This series implements just the shadow stack part of this feature, and just for userspace. The main use case for shadow stack is providing protection against return oriented programming attacks. It works by maintaining a secondary (shadow) stack using a special memory type that has protections against modification. When executing a CALL instruction, the processor pushes the return address to both the normal stack and to the special permission shadow stack. Upon RET, the processor pops the shadow stack copy and compares it to the normal stack copy. For more information, refer to the links below for the earlier versions of this patch set" Link: https://lore.kernel.org/lkml/20220130211838.8382-1-rick.p.edgecombe@intel.com/ Link: https://lore.kernel.org/lkml/20230613001108.3040476-1-rick.p.edgecombe@intel.com/ * tag 'x86_shstk_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (47 commits) x86/shstk: Change order of __user in type x86/ibt: Convert IBT selftest to asm x86/shstk: Don't retry vm_munmap() on -EINTR x86/kbuild: Fix Documentation/ reference x86/shstk: Move arch detail comment out of core mm x86/shstk: Add ARCH_SHSTK_STATUS x86/shstk: Add ARCH_SHSTK_UNLOCK x86: Add PTRACE interface for shadow stack selftests/x86: Add shadow stack test x86/cpufeatures: Enable CET CR4 bit for shadow stack x86/shstk: Wire in shadow stack interface x86: Expose thread features in /proc/$PID/status x86/shstk: Support WRSS for userspace x86/shstk: Introduce map_shadow_stack syscall x86/shstk: Check that signal frame is shadow stack mem x86/shstk: Check that SSP is aligned on sigreturn x86/shstk: Handle signals for shadow stack x86/shstk: Introduce routines modifying shstk x86/shstk: Handle thread shadow stack x86/shstk: Add user-mode shadow stack support ... |

selftests/bpf: Fix d_path test
Recent commit [1] broke d_path test, because now filp_close is not called
directly from sys_close, but eventually later when the file is finally
released.
As suggested by Hou Tao we don't need to re-hook the bpf program, but just
instead we can use sys_close_range to trigger filp_close synchronously.

Merge patch series "RISC-V: mm: Make SV48 the default address space"
Charlie Jenkins <charlie@rivosinc.com> says: Make sv48 the default address space for mmap as some applications currently depend on this assumption. Users can now select a desired address space using a non-zero hint address to mmap. Previously, requesting the default address space from mmap by passing zero as the hint address would result in using the largest address space possible. Some applications depend on empty bits in the virtual address space, like Go and Java, so this patch provides more flexibility for application developers. * b4-shazam-merge: RISC-V: mm: Document mmap changes RISC-V: mm: Update pgtable comment documentation RISC-V: mm: Add tests for RISC-V mm RISC-V: mm: Restrict address space for sv39,sv48,sv57 Link: https://lore.kernel.org/r/20230809232218.849726-1-charlie@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com> |

iommufd for 6.6
This includes a shared branch with VFIO:
- Enhance VFIO_DEVICE_GET_PCI_HOT_RESET_INFO so it can work with iommufd
FDs, not just group FDs. This removes the last place in the uAPI that
required the group fd.
- Give VFIO a new device node /dev/vfio/devices/vfioX (the so called cdev
node) which is very similar to the FD from VFIO_GROUP_GET_DEVICE_FD.
The cdev is associated with the struct device that the VFIO driver is
bound to and shows up in sysfs in the normal way.
- Add a cdev IOCTL VFIO_DEVICE_BIND_IOMMUFD which allows a newly opened
/dev/vfio/devices/vfioX to be associated with an IOMMUFD, this replaces
the VFIO_GROUP_SET_CONTAINER flow.
- Add cdev IOCTLs VFIO_DEVICE_[AT|DE]TACH_IOMMUFD_PT to allow the IOMMU
translation the vfio_device is associated with to be changed. This is a
significant new feature for VFIO as previously each vfio_device was
fixed to a single translation.
The translation is under the control of iommufd, so it can be any of
the different translation modes that iommufd is learning to create.
At this point VFIO has compilation options to remove the legacy interfaces
and in modern mode it behaves like a normal driver subsystem. The
/dev/vfio/iommu and /dev/vfio/groupX nodes are not present and each
vfio_device only has a /dev/vfio/devices/vfioX cdev node that represents
the device.
On top of this is built some of the new iommufd functionality:
- IOMMU_HWPT_ALLOC allows userspace to directly create the low level
IO Page table objects and affiliate them with IOAS objects that hold
the translation mapping. This is the basic functionality for the
normal IOMMU_DOMAIN_PAGING domains.
- VFIO_DEVICE_ATTACH_IOMMUFD_PT can be used to replace the current
translation. This is wired up to through all the layers down to the
driver so the driver has the ability to implement a hitless
replacement. This is necessary to fully support guest behaviors when
emulating HW (eg guest atomic change of translation)
- IOMMU_GET_HW_INFO returns information about the IOMMU driver HW that
owns a VFIO device. This includes support for the Intel iommu, and
patches have been posted for all the other server IOMMU.
Along the way are a number of internal items:
- New iommufd kapis iommufd_ctx_has_group(), iommufd_device_to_ictx(),
iommufd_device_to_id(), iommufd_access_detach(), iommufd_ctx_from_fd(),
iommufd_device_replace()
- iommufd now internally tracks iommu_groups as it needs some per-group
data
- Reorganize how the internal hwpt allocation flows to have more robust
locking
- Improve the access interfaces to support detach and replace of an IOAS
from an access
- New selftests and a rework of how the selftests creates a mock iommu
driver to be more like a real iommu driver

sound updates for 6.6-rc1
We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.
Here are some highlights:
ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups
ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including a
lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
Others:
- New test coverage including ASoC and topology tests in KUnit;
this also involves enabling UML builds of ALSA since that's the
default KUnit test environment which pulls in the addition of some
stubs to the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
- CS35L41 HD-audio sub-codec improvements
- Continued emu10k1 improvements

selftests/bpf: Fix flaky cgroup_iter_sleepable subtest
Occasionally, with './test_progs -j' on my vm, I will hit the
following failure:
test_cgrp_local_storage:PASS:join_cgroup /cgrp_local_storage 0 nsec
test_cgroup_iter_sleepable:PASS:skel_open 0 nsec
test_cgroup_iter_sleepable:PASS:skel_load 0 nsec
test_cgroup_iter_sleepable:PASS:attach_iter 0 nsec
test_cgroup_iter_sleepable:PASS:iter_create 0 nsec
test_cgroup_iter_sleepable:FAIL:cgroup_id unexpected cgroup_id: actual 1 != expected 2812
#48/5 cgrp_local_storage/cgroup_iter_sleepable:FAIL
#48 cgrp_local_storage:FAIL
Finally, I decided to do some investigation since the test is introduced
by myself. It turns out the reason is due to cgroup_fd with value 0.
In cgroup_iter, a cgroup_fd of value 0 means the root cgroup.
/* from cgroup_iter.c */
if (fd)
cgrp = cgroup_v1v2_get_from_fd(fd);
else if (id)
cgrp = cgroup_get_from_id(id);
else /* walk the entire hierarchy by default. */
cgrp = cgroup_get_from_path("/");
That is why we got cgroup_id 1 instead of expected 2812.
Why we got a cgroup_fd 0? Nobody should really touch 'stdin' (fd 0) in
test_progs. I traced 'close' syscall with stack trace and found the root
cause, which is a bug in bpf_obj_pinning.c. Basically, the code closed
fd 0 although it should not. Fixing the bug in bpf_obj_pinning.c also
resolved the above cgroup_iter_sleepable subtest failure.
Fixes:

Pull io_uring updates from Jens Axboe:
"Fairly quiet round in terms of features, mostly just improvements all
over the map for existing code. In detail:
- Initial support for socket operations through io_uring. Latter half
of this will likely land with the 6.7 kernel, then allowing things
like get/setsockopt (Breno)
- Cleanup of the cancel code, and then adding support for canceling
requests with the opcode as the key (me)
- Improvements for the io-wq locking (me)
- Fix affinity setting for SQPOLL based io-wq (me)
- Remove the io_uring userspace code. These were added initially as
copies from liburing, but all of them have since bitrotted and are
way out of date at this point. Rather than attempt to keep them in
sync, just get rid of them. People will have liburing available
anyway for these examples. (Pavel)
- Series improving the CQ/SQ ring caching (Pavel)
- Misc fixes and cleanups (Pavel, Yue, me)"

Networking changes for 6.6.
Core
----
- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with large
writes operations.
- Store netdevs in an xarray, to simplify iterating over netdevs.
- Refactor nexthop selection for multipath routes.
- Improve sched class lifetime handling.
- Add backup nexthop ID support for bridge.
- Implement drop reasons support in openvswitch.
- Several data races annotations and fixes.
- Constify the sk parameter of routing functions.
- Prepend kernel version to netconsole message.
Protocols
---------
- Implement support for TCP probing the peer being under memory
pressure.
- Remove hard coded limitation on IPv6 specific info placement
inside the socket struct.
- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
per socket scaling factor.
- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes.
- In-kernel support for the TLS alert protocol.
- Better support for UDP reuseport with connected sockets.
- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size.
- Get rid of additional ancillary per MPTCP connection struct socket.
- Implement support for BPF-based MPTCP packet schedulers.
- Format MPTCP subtests selftests results in TAP.
- Several new SMC 2.1 features including unique experimental options,
max connections per lgr negotiation, max links per lgr negotiation.
BPF
---
- Multi-buffer support in AF_XDP.
- Add multi uprobe BPF links for attaching multiple uprobes
and usdt probes, which is significantly faster and saves extra fds.
- Implement an fd-based tc BPF attach API (TCX) and BPF link support on
top of it.
- Add SO_REUSEPORT support for TC bpf_sk_assign.
- Support new instructions from cpu v4 to simplify the generated code and
feature completeness, for x86, arm64, riscv64.
- Support defragmenting IPv(4|6) packets in BPF.
- Teach verifier actual bounds of bpf_get_smp_processor_id()
and fix perf+libbpf issue related to custom section handling.
- Introduce bpf map element count and enable it for all program types.
- Add a BPF hook in sys_socket() to change the protocol ID
from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
- Add uprobe support for the bpf_get_func_ip helper.
- Check skb ownership against full socket.
- Support for up to 12 arguments in BPF trampoline.
- Extend link_info for kprobe_multi and perf_event links.
Netfilter
---------
- Speed-up process exit by aborting ruleset validation if a
fatal signal is pending.
- Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
Driver API
----------
- Page pool optimizations, to improve data locality and cache usage.
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
for raw ioctl() handling in drivers.
- Simplify genetlink dump operations (doit/dumpit) providing them
the common information already populated in struct genl_info.
- Extend and use the yaml devlink specs to [re]generate the split ops.
- Introduce devlink selective dumps, to allow SF filtering SF based on
handle and other attributes.
- Add yaml netlink spec for netlink-raw families, allow route, link and
address related queries via the ynl tool.
- Remove phylink legacy mode support.
- Support offload LED blinking to phy.
- Add devlink port function attributes for IPsec.

regmap: Updates for v6.6
This is a much quieter release than the past few, there's one small API
addition that I noticed a user for in ALSA and a bunch of cleanups:
- Provide an interface for determining if a register is present in the
cache and add a user of it in ALSA.
- Full support for dynamic allocations, following the temporary bodges
that were done as fixes in the previous release.
- Remove the unused and questionably working 64 bit support.

RCU pull request for v6.6
doc.2023.07.14b: Documentation updates. fixes.2023.08.16a: Miscellaneous fixes, perhaps most notably simplifying SRCU_NOTIFIER_INIT() as suggested. rcu-tasks.2023.07.24a: RCU Tasks updates, most notably treating Tasks RCU callbacks as lazy while still treating synchronous grace periods as urgent. Also fixes one bug that restores the ability to apply debug-objects to RCU Tasks and another that fixes a race condition that could result in false-positive failures of the boot-time self-test code. rcuscale.2023.07.14b: RCU-scalability performance-test updates, most notably adding the ability to measure the RCU-Tasks's grace-period kthread's CPU consumption. This proved quite useful for the rcu-tasks.2023.07.24a work. refscale.2023.07.14b: Reference-acquisition/release performance-test updates, including a fix for an uninitialized wait_queue_head_t. torture.2023.08.14a: Miscellaneous torture-test updates. torturescripts.2023.07.20a: Torture-test scripting updates, including removal of the non-longer-functional formal-verification scripts, test builds of individual RCU Tasks flavors, better diagnostics for loss of connectivity for distributed rcutorture tests, disabling of reboot loops in qemu/KVM-based rcutorture testing, and passing of init parameters to rcutorture's init program. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmTjkssTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jITND/9zEqYNbeFrcBs/YaHdoAjsNgOt1IYN csfF/KArVgdvmrwlV/nEaQMLaJcw9X7DVU5+7E2JbbDaB/2FSacseNyKk6mfgSVK /0rnTOXpqI9/T1HiJObWZvDQFuKL12bfteXWGJg1sMt2JUGZ4nAWhdZ3xRjp2XkO 89qB5r0fF8gyGwvQ3M29ss8T9Oy0uUNJmDY/QyVxHM6dhkpSAezFffKzD7C4zkSV WucRTpYJ7bs6otBGtVmwz3x60UAuLwcVfQyB+CTbnGLsps9yAYU+1DDVdm7olcr3 ARXMeboeodMvy9jWXhtbWRVAAob4lVUDXQN27kb4sBgroRQBfQXMuByRAU6s0VtX frOl6rlbORuAetsC8wFL0IFVn4yTpvXKbYw7h1MXTs7gVVbl33O9FieGvWu0r79/ VR4Xw+JbmYWtyvFV8Zaq4iIEcOe+PeNH6u0bPx+htsHYd1+DUG2UY0MVmJQ3a4sb ygejA6mguCk7KBzWab8wdDpgAfhNwg0T9a+LQYcaskuD5SSWjYqqg6i1ulqqqyiE bOfRKDX4mWmAobWKHLssqUrjiLbxfygIaHjCrt7rWJKPIs1bK/WfWa4JbrE0NRwK 9IDd1lWc9C+zoUpjyZWSG3ahK5lWo2u4sPNoRtMQjowjobIz1cBhaEwmFe72bG7C FCKb7Da2oUaLOw== =EujZ -----END PGP SIGNATURE----- Merge tag 'rcu.2023.08.21a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Documentation updates - Miscellaneous fixes, perhaps most notably simplifying SRCU_NOTIFIER_INIT() as suggested - RCU Tasks updates, most notably treating Tasks RCU callbacks as lazy while still treating synchronous grace periods as urgent.
