x86/kprobes: Update kcb status flag after singlestepping
Fix kprobes to update kcb (kprobes control block) status flag to
KPROBE_HIT_SSDONE even if the kp->post_handler is not set.
This bug may cause a kernel panic if another INT3 user runs right
after kprobes because kprobe_int3_handler() misunderstands the
INT3 is kprobe's single stepping INT3.

kprobes: Forbid probing on trampoline and BPF code areas
kernel_text_address() treats ftrace_trampoline, kprobe_insn_slot and bpf_text_address as valid kprobe addresses - which is not ideal. These text areas are removable and changeable without any notification to kprobes, and probing on them can trigger unexpected behavior: https://lkml.org/lkml/2022/7/26/1148 Considering that jump_label and static_call text are already forbiden to probe, kernel_text_address() should be replaced with core_kernel_text() and is_module_text_address() to check other text areas which are unsafe to kprobe.

This was a fairly quiet cycle for the locking subsystem:
- lockdep: Fix a handful of the more complex lockdep_init_map_*() primitives
that can lose the lock_type & cause false reports. No such mishap was
observed in the wild.
- jump_label improvements: simplify the cross-arch support of
initial NOP patching by making it arch-specific code (used on MIPS only),
and remove the s390 initial NOP patching that was superfluous.

This cycle's scheduler updates for v6.0 are:
Load-balancing improvements:
============================
- Improve NUMA balancing on AMD Zen systems for affine workloads.
- Improve the handling of reduced-capacity CPUs in load-balancing.
- Energy Model improvements: fix & refine all the energy fairness metrics (PELT),
and remove the conservative threshold requiring 6% energy savings to
migrate a task. Doing this improves power efficiency for most workloads,
and also increases the reliability of energy-efficiency scheduling.
- Optimize/tweak select_idle_cpu() to spend (much) less time searching
for an idle CPU on overloaded systems. There's reports of several
milliseconds spent there on large systems with large workloads ...
[ Since the search logic changed, there might be behavioral side effects. ]
- Improve NUMA imbalance behavior. On certain systems
with spare capacity, initial placement of tasks is non-deterministic,
and such an artificial placement imbalance can persist for a long time,
hurting (and sometimes helping) performance.
The fix is to make fork-time task placement consistent with runtime
NUMA balancing placement.
Note that some performance regressions were reported against this,
caused by workloads that are not memory bandwith limited, which benefit
from the artificial locality of the placement bug(s). Mel Gorman's
conclusion, with which we concur, was that consistency is better than
random workload benefits from non-deterministic bugs:
"Given there is no crystal ball and it's a tradeoff, I think it's
better to be consistent and use similar logic at both fork time
and runtime even if it doesn't have universal benefit."
- Improve core scheduling by fixing a bug in sched_core_update_cookie() that
caused unnecessary forced idling.
- Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs for newly
woken tasks.
- Fix a newidle balancing bug that introduced unnecessary wakeup latencies.
ABI improvements/fixes:
=======================
- Do not check capabilities and do not issue capability check denial messages
when a scheduler syscall doesn't require privileges. (Such as increasing niceness.)
- Add forced-idle accounting to cgroups too.
- Fix/improve the RSEQ ABI to not just silently accept unknown flags.
(No existing tooling is known to have learned to rely on the previous behavior.)
- Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.
Optimizations:
==============
- Optimize & simplify leaf_cfs_rq_list()
- Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().
Misc fixes & cleanups:
======================
- Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.
- Fix a full-NOHZ bug that can in some cases result in the tick not being
re-enabled when the last SCHED_RT task is gone from a runqueue but there's
still SCHED_OTHER tasks around.
- Various PREEMPT_RT related fixes.
- Misc cleanups & smaller fixes.

arm64 updates for 5.20
- Remove unused generic cpuidle support (replaced by PSCI version)
- Fix documentation describing the kernel virtual address space
- Handling of some new CPU errata in Arm implementations
- Rework of our exception table code in preparation for handling
machine checks (i.e. RAS errors) more gracefully
- Switch over to the generic implementation of ioremap()
- Fix lockdep tracking in NMI context
- Instrument our memory barrier macros for KCSAN
- Rework of the kPTI G->nG page-table repainting so that the MMU remains
enabled and the boot time is no longer slowed to a crawl for systems
which require the late remapping
- Enable support for direct swapping of 2MiB transparent huge-pages on
systems without MTE
- Fix handling of MTE tags with allocating new pages with HW KASAN
- Expose the SMIDR register to userspace via sysfs
- Continued rework of the stack unwinder, particularly improving the
behaviour under KASAN
- More repainting of our system register definitions to match the
architectural terminology
- Improvements to the layout of the vDSO objects
- Support for allocating additional bits of HWCAP2 and exposing
FEAT_EBF16 to userspace on CPUs that support it
- Considerable rework and optimisation of our early boot code to reduce
the need for cache maintenance and avoid jumping in and out of the
kernel when handling relocation under KASLR
- Support for disabling SVE and SME support on the kernel command-line
- Support for the Hisilicon HNS3 PMU
- Miscellanous cleanups, trivial updates and minor fixes

Pull arm64 updates from Will Deacon:
"Highlights include a major rework of our kPTI page-table rewriting
code (which makes it both more maintainable and considerably faster in
the cases where it is required) as well as significant changes to our
early boot code to reduce the need for data cache maintenance and
greatly simplify the KASLR relocation dance.

Pull fs idmapping updates from Christian Brauner:
"This introduces the new vfs{g,u}id_t types we agreed on. Similar to
k{g,u}id_t the new types are just simple wrapper structs around
regular {g,u}id_t types.
They allow to establish a type safety boundary in the VFS for idmapped
mounts preventing confusion betwen {g,u}ids mapped into an idmapped
mount and {g,u}ids mapped into the caller's or the filesystem's
idmapping.
An initial set of helpers is introduced that allows to operate on
vfs{g,u}id_t types. We will remove all references to non-type safe
idmapped mounts helpers in the very near future. The patches do
already exist.
This converts the core attribute changing codepaths which become
significantly easier to reason about because of this change.
Just a few highlights here as the patches give detailed overviews of
what is happening in the commit messages:
- The kernel internal struct iattr contains type safe vfs{g,u}id_t
values clearly communicating that these values have to take a given
mount's idmapping into account.
- The ownership values placed in struct iattr to change ownership are
identical for idmapped and non-idmapped mounts going forward. This
also allows to simplify stacking filesystems such as overlayfs that
change attributes In other words, they always represent the values.
- Instead of open coding checks for whether ownership changes have
been requested and an actual update of the inode is required we now
have small static inline wrappers that abstract this logic away
removing a lot of code duplication from individual filesystems that
all open-coded the same checks"

Delay the completion of lockspace creation until one full recovery cycle has completed. This allows more error cases to be returned to the caller. . Remove warnings from the locking layer about delayed network replies. The recently added midcomms warnings are much more useful. .

fs: dlm: move kref_put assert for lkb structs
The unhold_lkb() function decrements the lock's kref, and asserts that the ref count was not the final one. Use the kref_put release function (which should not be called) to call the assert, rather than doing the assert based on the kref_put return value. Using kill_lkb() as the release function doesn't make sense if we only want to assert. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com> |

fs: dlm: add deprecation Kconfig and warnings for timeouts
This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option that must be enabled to use two timeout-related features that we intend to remove in kernel v6.2. Warnings are printed if either is enabled and used. Neither has ever been used as far as we know. . The DLM_LSFL_TIMEWARN lockspace creation flag will be removed, along with the associated configfs entry for setting the timeout. Setting the flag and configfs file would cause dlm to track how long locks were waiting for reply messages. After a timeout, a kernel message would be logged, and a netlink message would be sent to userspace. Recently, midcomms messages have been added that produce much better logging about actual problems with messages. No use has ever been found for the netlink messages. . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT flag with a timeout value to be set in lock requests. The lock request would be cancelled after the timeout.

rseq: Kill process when unknown flags are encountered in ABI structures
rseq_abi()->flags and rseq_abi()->rseq_cs->flags 29 upper bits are currently unused. The current behavior when those bits are set is to ignore them. This is not an ideal behavior, because when future features will start using those flags, if user-space fails to correctly validate that the kernel indeed supports those flags (e.g. with a new sys_rseq flags bit) before using them, it may incorrectly assume that the kernel will handle those flags way when in fact those will be silently ignored on older kernels. Validating that unused flags bits are cleared will allow a smoother transition when those flags will start to be used by allowing applications to fail early, and obviously, when they attempt to use the new flags on an older kernel that does not support them.

rseq: Deprecate RSEQ_CS_FLAG_NO_RESTART_ON_* flags
The pretty much unused RSEQ_CS_FLAG_NO_RESTART_ON_* flags introduce complexity in rseq, and are subtly buggy [1]. Solving those issues requires introducing additional complexity in the rseq implementation for each supported architecture. Considering that it complexifies the rseq ABI, I am proposing that we deprecate those flags. [2] So far there appears to be consensus from maintainers of user-space projects impacted by this feature that its removal would be a welcome simplification. [3] The deprecation approach proposed here is to issue WARN_ON_ONCE() when encountering those flags and kill the offending process with sigsegv. This should allow us to quickly identify whether anyone yells at us for removing this.

erofs: update ctx->pos for every emitted dirent
erofs_readdir update ctx->pos after filling a batch of dentries
and it may cause dir/files duplication for NFS readdirplus which
depends on ctx->pos to fill dir correctly. So update ctx->pos for
every emitted dirent in erofs_fill_dentries to fix it.
Also fix the update of ctx->pos when the initial file position has
exceeded nameoff.

mm/hmm: fault non-owner device private entries
If hmm_range_fault() is called with the HMM_PFN_REQ_FAULT flag and a
device private PTE is found, the hmm_range::dev_private_owner page is used
to determine if the device private page should not be faulted in.
However, if the device private page is not owned by the caller,
hmm_range_fault() returns an error instead of calling migrate_to_ram() to
fault in the page.
For example, if a page is migrated to GPU private memory and a RDMA fault
capable NIC tries to read the migrated page, without this patch it will
get an error. With this patch, the page will be migrated back to system
memory and the NIC will be able to read the data.
