firewire updates for v6.12
The batch of changes includes the followwing:
- Replacing tasklet with usual workqueue for isochronous context
- Replacing IDR with XArray
- Utilizing guard macro where possible
- Printing deprecation warning when enabling debug parameter of
firewire-ohci module
Additionally, it includes a single patch for sound subsystem which the
subsystem maintainer acked:
- Switching to nonatomic PCM operation
In FireWire subsystem, tasklet has been used as the bottom half of 1394
OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
been available, and some developers have proposed replacing tasklet with
BH workqueue. While it is fortunate that developers are still considering
the legacy subsystem, a simple replacement is not necessarily suitable.
As a first step towards dropping tasklet, I've investigated the
feasibility for 1394 OHCI isochronous context, and concluded that usual
workqueue is available. In the context, the batch of packets is processed
in the specific queue, thus the timing jitter caused by task scheduling is
not so critical. Additionally, DMA transmission can be scheduled
per-packet basis, therefore the context can be sleep between the operation
of transmissions. Furthermore, in-kernel protocol implementation involves
some CPU-bound tasks, which can sometimes consumes CPU time so long. These
characteristics suggest that usual workqueue is suitable, through BH
workqueues are not.
The replacement with usual workqueue allows unit drivers to process the
content of packets in non-atomic context. It brings some reliefs to some
drivers in sound subsystem that spin-lock is not mandatory anymore during
isochronous packet processing.

bcachefs changes for 6.12-rc1
rcu_pending, btree key cache rework: this solves lock contenting in the key cache, eliminating the biggest source of the srcu lock hold time warnings, and drastically improving performance on some metadata heavy workloads - on multithreaded creates we're now 3-4x faster than xfs. We're now using an rhashtable instead of the system inode hash table; this is another significant performance improvement on multithreaded metadata workloads, eliminating more lock contention. for_each_btree_key_in_subvolume_upto(): new helper for iterating over keys within a specific subvolume, eliminating a lot of open coded "subvolume_get_snapshot()" and also fixing another source of srcu lock time warnings, by running each loop iteration in its own transaction (as the existing for_each_btree_key() does). More work on btree_trans locking asserts; we now assert that we don't hold btree node locks when trans->locked is false, which is important because we don't use lockdep for tracking individual btree node locks. Some cleanups and improvements in the bset.c btree node lookup code, from Alan. Rework of btree node pinning, which we use in backpointers fsck. The old hacky implementation, where the shrinker just skipped over nodes in the pinned range, was causing OOMs; instead we now use another shrinker with a much higher seeks number for pinned nodes. Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue where rebalance would sometimes fall back to allocating from the full filesystem, which is not what we want when it's trying to move data to a specific target. Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache allocations. Idmap mounts are now supported - Hongbo. Rename whiteouts are now supported - Hongbo. Erasure coding can now handle devices being marked as failed, or forcibly removed. We still need the evacuate path for erasure coding, but it's getting very close to ready for people to start using. Status, and when will we be taking off experimental: ---------------------------------------------------- Going by critical, user facing bugs getting found and fixed, we're nearly there. There are a couple key items that need to be finished before we can take off the experimental label: - The end-user experience is still pretty painful when the root filesystem needs a fsck; we need some form of limited self healing so that necessary repair gets run automatically. Errors (by type) are recorded in the superblock, so what we need to do next is convert remaining inconsistent() errors to fsck() errors (so that all runtime inconsistencies are logged in the superblock), and we need to go through the list of fsck errors and classify them by which fsck passes are needed to repair them. - We need comprehensive torture testing for all our repair paths, to shake out remaining bugs there. Thomas has been working on the tooling for this, so this is coming soonish. Slightly less critical items: - We need to improve the end-user experience for degraded mounts: right now, a degraded root filesystem means dropping to an initramfs shell or somehow inputting mount options manually (we don't want to allow degraded mounts without some form of user input, except on unattended servers) - we need the mount helper to prompt the user to allow mounting degraded, and make sure this works with systemd. - Scalabiity: we have users running 100TB+ filesystems, and that's effectively the limit right now due to fsck times. We have some reworks in the pipeline to address this, we're aiming to make petabyte sized filesystems practical. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmbvHQoACgkQE6szbY3K bnYfAw/+IXQ43/O+Jzs0MLD7pKZnrlbHiX9FqYLazD40vWvkyRTQOwgTn8pVNhq3 4YWmtuZyqh036YC+bGqYFOhz20YetS5UdgbClpwmc99JJ6xsY+Z1mdpYfz5oq1Dw /pBX5iYb3rAt8UbQoZ8lcWM+GpT3GKJVgJuiLB2gRp9gATFesuh+0qU42oIVVVU5 4y3VhDBUmRk4XqEnk8hr7EIDMW0wWP3aptxYMZzeUPW0x1cEQ+FWrJo5D6lXv2KK dKv3MogvA0FFNi/eNexclPiu2pXtI7vrxT7umsxAICHLt41rWpV5ttE6io3bC4ZN qvwF9w2CpmKPKchFru9PO+QrWHVR7e6bphwf3TzyoKZ7tTn42f1RQlub7gBzI3bz ai5ZwGRIvpUoPVBj+CO+Ipog81uUb23Ma+gXg1akEFBOAb+o7I3KOOSBh5l+0cHj 3Ov1n0TLcsoO2cqoqfsV2QubW9YcWEZ76g5mKwQnUn8Cs6Fp0wWaIyK9aNkIAxcr tNDPGtH1gKitxUvju5i/LyI7y1UoeFvqJFee0VsU6QnixHn1ySzhePsJt6UEnIJT Ia3C96Igqu2mV9FxhfGHj/qi7TGjqqkZHa8+B610cDpgf15cx7Ps2DYjkuQMFCqZ Q3Q1o5De9roRq5xF2hLiYJCbzJKqd5ichFsBtLQuX572ICxbICg= =oVCy -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-09-21' of git://evilpiepirate.org/bcachefs Pull bcachefs updates from Kent Overstreet: - rcu_pending, btree key cache rework: this solves lock contenting in the key cache, eliminating the biggest source of the srcu lock hold time warnings, and drastically improving performance on some metadata heavy workloads - on multithreaded creates we're now 3-4x faster than xfs. - We're now using an rhashtable instead of the system inode hash table; this is another significant performance improvement on multithreaded metadata workloads, eliminating more lock contention. - for_each_btree_key_in_subvolume_upto(): new helper for iterating over keys within a specific subvolume, eliminating a lot of open coded "subvolume_get_snapshot()" and also fixing another source of srcu lock time warnings, by running each loop iteration in its own transaction (as the existing for_each_btree_key() does). - More work on btree_trans locking asserts; we now assert that we don't hold btree node locks when trans->locked is false, which is important because we don't use lockdep for tracking individual btree node locks. - Some cleanups and improvements in the bset.c btree node lookup code, from Alan. - Rework of btree node pinning, which we use in backpointers fsck.

mfd: tc3589x: Drop vendorless compatible string from match table
There's no need to list "tc3589x" in the DT match table. The I2C core
will strip any vendor prefix and match against the i2c_device_id table
which has an "tc3589x" entry.
Probably "tc3589x" and TC3589X_UNKNOWN could be removed altogether.
Use of that compatible was only on some STE platforms and was dropped
in 2013. There were ABI breaks in 2014 claiming no DTs in the wild. See

seqcount: replace smp_rmb() in read_seqcount() with load acquire
Many architectures support load acquire which can replace a memory
barrier and save some cycles.
A typical sequence
do {
seq = read_seqcount_begin(&s);
<something>
} while (read_seqcount_retry(&s, seq);
requires 13 cycles on an N1 Neoverse arm64 core (Ampere Altra, to be
specific) for an empty loop. Two read memory barriers are needed. One
for each of the seqcount_* functions.
We can replace the first read barrier with a load acquire of the
seqcount which saves us one barrier.
On the Altra doing so reduces the cycle count from 13 to 8.
According to ARM, this is a general improvement for the ARM64
architecture and not specific to a certain processor.
See
https://developer.arm.com/documentation/102336/0100/Load-Acquire-and-Store-Release-instructions
"Weaker ordering requirements that are imposed by Load-Acquire and
Store-Release instructions allow for micro-architectural
optimizations, which could reduce some of the performance impacts that
are otherwise imposed by an explicit memory barrier.
If the ordering requirement is satisfied using either a Load-Acquire
or Store-Release, then it would be preferable to use these
instructions instead of a DMB"
[ NOTE! This is my original minimal patch that unconditionally switches
over to using smp_load_acquire(), instead of the much more involved
and subtle patch that Christoph Lameter wrote that made it
conditional.
But Christoph gets authorship credit because I had initially thought
that we needed the more complex model, and Christoph ran with it it
and did the work. Only after looking at code generation for all the
relevant architectures, did I come to the conclusion that nobody
actually really needs the old "smp_rmb()" model.
Even architectures without load-acquire support generally do as well
or better with smp_load_acquire().
So credit to Christoph, but if this then causes issues on other
architectures, put the blame solidly on me.
Also note as part of the ruthless simplification, this gets rid of the
overly subtle optimization where some code uses a non-barrier version
of the sequence count (see the __read_seqcount_begin() users in
fs/namei.c). They then play games with their own barriers and/or with
nested sequence counts.
Those optimizations are literally meaningless on x86, and questionable
elsewhere. If somebody can show that they matter, we need to re-do
them more cleanly than "use an internal helper". - Linus ]

Merge branch 'address-masking'
Merge user access fast validation using address masking. This allows architectures to optionally use a data dependent address masking model instead of a conditional branch for validating user accesses. That avoids the Spectre-v1 speculation barriers. Right now only x86-64 takes advantage of this, and not all architectures will be able to do it. It requires a guard region between the user and kernel address spaces (so that you can't overflow from one to the other), and an easy way to generate a guaranteed-to-fault address for invalid user pointers. Also note that this currently assumes that there is no difference between user read and write accesses. If extended to architectures like powerpc, we'll also need to separate out the user read-vs-write cases. * address-masking: x86: make the masked_user_access_begin() macro use its argument only once x86: do the user address masking outside the user access area x86: support user address masking instead of non-speculative conditional |

This doesn't actually matter for any of the current users, but before merging it mainline, make sure we don't have any surprising semantics. We don't actually want to use an inline function here, because we want to allow - but not require - const pointer arguments, and return them as such. But we already had a local auto-type variable, so let's just use it to avoid any possible double evaluation. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

ring-buffer: Updates for v6.12:
- Merged v6.11-rc3 into trace/ring-buffer/core
The v6.10 ring buffer pull request was not made due to Mathieu Desnoyers
making a comment to the pull request. Mathieu and I resolved it on IRC,
but we did not let Linus know that it was resolved. Linus did not do the
pull thinking it still had some unresolved issues.
The ring buffer work for 6.12 was dependent on both this pull request as
well as the reserve_mem kernel command line option that was going upstream
through the memory management tree. The ring buffer repo was being used by
others so it could not be rebased. In order to continue the work, the
v6.11-rc3 branch was pulled in to get access to the reserve_mem work.
This has the 6.11 pull request that did not make it into 6.11, which was:
tracing/ring-buffer: Have persistent buffer across reboots
This allows for the tracing instance ring buffer to stay persistent across
reboots. The way this is done is by adding to the kernel command line:
trace_instance=boot_map@0x285400000:12M
This will reserve 12 megabytes at the address 0x285400000, and then map
the tracing instance "boot_map" ring buffer to that memory. This will
appear as a normal instance in the tracefs system:
/sys/kernel/tracing/instances/boot_map
A user could enable tracing in that instance, and on reboot or kernel
crash, if the memory is not wiped by the firmware, it will recreate the
trace in that instance. For example, if one was debugging a shutdown of a
kernel reboot:
# cd /sys/kernel/tracing
# echo function > instances/boot_map/current_tracer
# reboot
[..]
# cd /sys/kernel/tracing
# tail instances/boot_map/trace

On reboot, the buffer is examined to make sure it is valid. The validation
check even steps through every event to make sure the meta data of the
event is correct. If any test fails, it will simply reset the buffer, and
the buffer will be empty on boot.
The new changes for 6.12 are:
- Allow the tracing persistent boot buffer to use the "reserve_mem" option
Instead of having the admin find a physical address to store the persistent
buffer, which can be very tedious if they have to administrate several
different machines, allow them to use the "reserve_mem" option that will
find a location for them. It is not as reliable because of KASLR, as the
loading of the kernel in different locations can cause the memory
allocated to be inconsistent. Booting with "nokaslr" can make reserve_mem
more reliable.
- Have function graph tracer handle offsets from a previous boot.
The ring buffer output from a previous boot may have different addresses
due to kaslr. Have the function graph tracer handle these by using the
delta from the previous boot to the new boot address space.
- Only reset the saved meta offset when the buffer is started or reset
In the persistent memory meta data, it holds the previous address space
information, so that it can calculate the delta to have function tracing
work. But this gets updated after being read to hold the new address
space. But if the buffer isn't used for that boot, on reboot, the delta is
now calculated from the previous boot and not the boot that holds the data
in the ring buffer. This causes the functions not to be shown. Do not save
the address space information of the current kernel until it is being
recorded.
- Add a magic variable to test the valid meta data
Add a magic variable in the meta data that can also be used for
validation. The validator of the previous buffer doesn't need this magic
data, but it can be used if the meta data is changed by a new kernel, which
may have the same format that passes the validator but is used
differently. This magic number can also be used as a "versioning" of the
meta data.
- Align user space mapped ring buffer sub buffers to improve TLB entries
Linus mentioned that the mapped ring buffer sub buffers were misaligned
between the meta page and the sub-buffers, so that if the sub-buffers were
bigger than PAGE_SIZE, it wouldn't allow the TLB to use bigger entries.
- Add new kernel command line "traceoff" to disable tracing on boot for instances
If tracing is enabled for a boot instance, there needs a way to be able to
disable it on boot so that new events do not get entered into the ring
buffer and be mixed with events from a previous boot, as that can be
confusing.
- Allow trace_printk() to go to other instances
Currently, trace_printk() can only go to the top level instance. When
debugging with a persistent buffer, it is really useful to be able to add
trace_printk() to go to that buffer, so that you have access to them after
a crash.
- Do not use "bin_printk()" for traces to a boot instance
The bin_printk() saves only a pointer to the printk format in the ring
buffer, as the reader of the buffer can still have access to it. But this
is not the case if the buffer is from a previous boot. If the
trace_printk() is going to a "persistent" buffer, it will use the slower
version that writes the printk format into the buffer.
- Add command line option to allow trace_printk() to go to an instance
Allow the kernel command line to define which instance the trace_printk()
goes to, instead of forcing the admin to set it for every boot via the
tracefs options.
- Start a document that explains how to use tracefs to debug the kernel
- Add some more kernel selftests to test user mapped ring buffer

ktest.pl updates for 6.12:
- Add notification of build warnings for all tests Currently, the build will only fail on warnings if the ktest config file states that it should fail or if the compile is done with -Werror. This has allowed warnings to sneak in if it doesn't fail. Add a notification at the end of the test that will state that warnings were found in the build so that the developer will be aware of it. - Fix the grub2 parser to not return the wrong kernel index ktest.pl can read the grub.cfg file to know what kernel to boot to via grub-reboot. This requires knowing the index that the kernel is referenced by in the grub.cfg file. Some distros have logic to determine the menuentry that can cause the ktest.pl to come up with the wrong index and boot the wrong kernel. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZu+6uBQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6quXqAQCfuvT+tQucqGOobqnMjmHf3BEXLwl4 bH5uzWnibT2jLAD+K9JmiY9HYWB7+ozUqRRCJBJFbyH/PH+yI7f2C1KccAM= =turg -----END PGP SIGNATURE----- Merge tag 'ktest-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest Pull ktest updates from Steven Rostedt: - Add notification of build warnings for all tests Currently, the build will only fail on warnings if the ktest config file states that it should fail or if the compile is done with '-Werror'.

- Fix bitfields offsets and sizes.
- Initial support for PowerPC, using libcapstone and the usual objdump
disassembly parsing routines.
- Add support for disassembling and addr2line using the LLVM libraries,
speeding up those operations.

- Intel branch counters (LBR event logging) support, only available in recent
Intel processors, for instance, the new "brcntr" field can be asked from
'perf script' to print the information collected from this feature:
$ perf script -F +brstackinsn,+brcntr

showing/filtering command line options.
- Varios improvements to the 'perf probe', including 'perf test' regression
testings.
- Introduce the 'perf check', initially to check if some feature is in place,
using it in 'perf test'.
- Various fixes for 32-bit systems.
- Address more leak sanitizer failures.
- Fix memory leaks (LBR, disasm lock ops, etc).
- More reference counting fixes (branch_info, etc).
- Constify 'struct perf_tool' parameters to improve code generation and reduce
the chances of having its internals changed, which isn't expected.
- More constifications in various other places.
- Add more build tests, including for JEVENTS.
- Add more 'perf test' entries ('perf record LBR', pipe/inject, --setup-filter,
'perf ftrace', 'cgroup sampling', etc).
- Inject build ids for all entries in a call chain in 'perf inject', not just
for the main sample.
- Improve the BPF based sample filter, allowing root to setup filters in bpffs
that then can be used by non-root users.
- Allow filtering by cgroups with the BPF based sample filter.
- Allow a more compact way for 'perf mem report' using the -T/--type-profile and
also provide a --sort option similar to the one in 'perf report', 'perf top',
to setup the sort order manually.
- Fix --group behavior in 'perf annotate' when leader has no samples, where it
was not showing anything even when other events in the group had samples.
- Fix spinlock and rwlock accounting in 'perf lock contention'
- Fix libsubcmd fixdep Makefile dependencies.
- Improve 'perf ftrace' error message when ftrace isn't available.
- Update various Intel JSON vendor event files.
- ARM64 CoreSight hardware tracing infrastructure improvements, mostly not
visible to users.
- Update power10 JSON events.

perf: Fix topology_sibling_cpumask check warning on ARM
The below warning is triggered when building with arm
multi_v7_defconfig.
kernel/events/core.c: In function 'perf_event_setup_cpumask':
kernel/events/core.c:14012:13: warning: the comparison will always evaluate as 'true' for the address of 'thread_sibling' will never be NULL [-Waddress]
14012 | if (!topology_sibling_cpumask(cpu)) {
The perf_event_init_cpu() may be invoked at the early boot stage, while
the topology_*_cpumask hasn't been initialized yet. The check is to
specially handle the case, and initialize the perf_online_<domain>_masks
on the boot CPU.
X86 uses a per-cpu cpumask pointer, which could be NULL at the early
boot stage. However, ARM uses a global variable, which never be NULL.
Use perf_online_mask as an indicator instead. Only initialize the
perf_online_<domain>_masks when perf_online_mask is empty.
Fix a typo as well.

Merge tag 'bpf-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Pull bpf updates from Alexei Starovoitov:
- Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
corresponding support in LLVM.
It is similar to existing 'no_caller_saved_registers' attribute in
GCC/LLVM with a provision for backward compatibility. It allows
compilers generate more efficient BPF code assuming the verifier or
JITs will inline or partially inline a helper/kfunc with such
attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
bpf_get_smp_processor_id are the first set of such helpers.
- Harden and extend ELF build ID parsing logic.
When called from sleepable context the relevants parts of ELF file
will be read to find and fetch .note.gnu.build-id information. Also
harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.
- Improvements and fixes for sched-ext:
- Allow passing BPF iterators as kfunc arguments
- Make the pointer returned from iter_next method trusted
- Fix x86 JIT convergence issue due to growing/shrinking conditional
jumps in variable length encoding
- BPF_LSM related:
- Introduce few VFS kfuncs and consolidate them in
fs/bpf_fs_kfuncs.c
- Enforce correct range of return values from certain LSM hooks
- Disallow attaching to other LSM hooks
- Prerequisite work for upcoming Qdisc in BPF:
- Allow kptrs in program provided structs
- Support for gen_epilogue in verifier_ops
- Important fixes:
- Fix uprobe multi pid filter check
- Fix bpf_strtol and bpf_strtoul helpers
- Track equal scalars history on per-instruction level
- Fix tailcall hierarchy on x86 and arm64
- Fix signed division overflow to prevent INT_MIN/-1 trap on x86
- Fix get kernel stack in BPF progs attached to tracepoint:syscall
- Selftests:
- Add uprobe bench/stress tool
- Generate file dependencies to drastically improve re-build time
- Match JIT-ed and BPF asm with __xlated/__jited keywords
- Convert older tests to test_progs framework
- Add support for RISC-V
- Few fixes when BPF programs are compiled with GCC-BPF backend
(support for GCC-BPF in BPF CI is ongoing in parallel)
- Add traffic monitor
- Enable cross compile and musl libc

bcachefs: return err ptr instead of null in read sb clean
syzbot reported a null-ptr-deref in bch2_fs_start. [0] When a sb is marked clear but doesn't have a clean section bch2_read_superblock_clean returns NULL which PTR_ERR_OR_ZERO lets through, eventually leading to a null ptr dereference down the line. Adjust read sb clean to return an ERR_PTR indicating the invalid clean section.
