Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This extends the netfs helper library that network filesystems can use
to replace their own implementations. Both afs and 9p are ported. cifs
is ready as well but the patches are way bigger and will be routed
separately once this is merged. That will remove lots of code as well.
The overal goal is to get high-level I/O and knowledge of the page
cache and ouf of the filesystem drivers. This includes knowledge about
the existence of pages and folios
The pull request converts afs and 9p. This removes about 800 lines of
code from afs and 300 from 9p. For 9p it is now possible to do writes
in larger than a page chunks. Additionally, multipage folio support
can be turned on for 9p. Separate patches exist for cifs removing
another 2000+ lines. I've included detailed information in the
individual pulls I took.
Summary:
- Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
calls to prevent these from happening at the same time.
- Support for direct and unbuffered I/O.
- Support for write-through caching in the page cache.
- O_*SYNC and RWF_*SYNC writes use write-through rather than writing
to the page cache and then flushing afterwards.
- Support for write-streaming.
- Support for write grouping.
- Skip reads for which the server could only return zeros or EOF.
- The fscache module is now part of the netfs library and the
corresponding maintainer entry is updated.
- Some helpers from the fscache subsystem are renamed to mark them as
belonging to the netfs library.
- Follow-up fixes for the netfs library.
- Follow-up fixes for the 9p conversion"

Pull gpio fixes from Bartosz Golaszewski:
"Apart from some regular driver fixes there's a relatively big revert
of the locking changes that were introduced to GPIOLIB in this merge
window.
This is because it turned out that some legacy GPIO interfaces - that
need to translate a number from the global GPIO numberspace to the
address of the relevant descriptor, thus running a GPIO device lookup
and taking the GPIO device list lock - are still used in old code from
atomic context resulting in "scheduling while atomic" errors.
I'll try to make the read-only part of the list access entirely
lockless using SRCU but this will take some time so let's go back to
the old global spinlock for now.
Summary:
- revert the changes aiming to use a read-write semaphore to protect
the list of GPIO devices due to calls to legacy API taking that
lock from atomic context in old code
- fix inverted logic in DEFINE_FREE() for GPIO device references
- check the return value of bgpio_init() in gpio-mlxbf3

- fix a duplicate cleanup in an error path introduced in

- fix an out-of-bounds access
In practise it doesn't happen - otherwise someone would have noticed
since v5.17-rc1 I guess - because the device tree binding for the two
drivers using of_pwm_single_xlate() only have args->args_count == 1.
A device-tree that doesn't conform to the respective bindings could
trigger that easily however.
- correct the request callback of the jz4740 pwm driver which used
dev_err_probe() long after .probe() completed.
This is conceptually wrong because dev_err_probe() might call
device_set_deferred_probe_reason() which is nonsensical after the
driver is bound.

"The bulk of this update is support for enumerating the performance
capabilities of CXL memory targets and connecting that to a platform
CXL memory QoS class. Some follow-on work remains to hook up this data
into core-mm policy, but that is saved for v6.9.
The next significant update is unifying how CXL event records (things
like background scrub errors) are processed between so called
"firmware first" and native error record retrieval. The CXL driver
handler that processes the record retrieved from the device mailbox is
now the handler for that same record format coming from an EFI/ACPI

- Remove "lookup" parameter of create_dir_dentry() and
create_file_dentry(). These functions were called by lookup and the
readdir logic, where readdir needed it to up the ref count of the
dentry but the lookup did not. A "lookup" parameter was passed in to
tell it what to do, but this complicated the code. It is better to
just always up the ref count and require the caller to decrement it,
even for lookup.
- Modify the .iterate_shared callback to not use the dcache_readdir()

removes the need for eventfs to hijack the file->private_data from
the dcache_readdir() "cursor" pointer, and makes the code a bit more
sane
- Use the root and instance inodes for default ownership. Instead of
walking the dentry tree and updating each dentry gid, use the
getattr(), setattr() and permission() callbacks to set the ownership

Pull tracing updates from Steven Rostedt:
- Allow kernel trace instance creation to specify what events are
created
Inside the kernel, a subsystem may create a tracing instance that it
can use to send events to user space. This sub-system may not care
about the thousands of events that exist in eventfs. Allow the
sub-system to specify what sub-systems of events it cares about, and
only those events are exposed to this instance.
- Allow the ring buffer to be broken up into bigger sub-buffers than
just the architecture page size.
A new tracefs file called "buffer_subbuf_size_kb" is created. The
user can now specify a minimum size the sub-buffer may be in
kilobytes. Note, that the implementation currently make the
sub-buffer size a power of 2 pages (1, 2, 4, 8, 16, ...) but the user
only writes in kilobyte size, and the sub-buffer will be updated to
the next size that it will can accommodate it. If the user writes in
10, it will change the size to be 4 pages on x86 (16K), as that is
the next available size that can hold 10K pages.
- Update the debug output when a corrupt time is detected in the ring
buffer. If the ring buffer detects inconsistent timestamps, there's a
debug config options that will dump the contents of the meta data of
the sub-buffer that is used for debugging. Add some more information
to this dump that helps with debugging.
- Add more timestamp debugging checks (only triggers when the config is
enabled)
- Increase the trace_seq iterator to 2 page sizes.
- Allow strings written into tracefs_marker to be larger. Up to just
under 2 page sizes (based on what trace_seq can hold).
- Increase the trace_maker_raw write to be as big as a sub-buffer can
hold.
- Remove 32 bit time stamp logic, now that the rb_time_cmpxchg() has
been removed.

The majority of the code here is the kernel telling the TDX module
which memory to protect and handing some additional memory over to it
to use to store TDX module metadata. That sounds pretty simple, but
the TDX architecture is rather flexible and it takes quite a bit of
back-and-forth to say, "just protect all memory, please."
There is also some code tacked on near the end of the series to handle

====================
Netfilter fixes for net
The following batch contains Netfilter fixes for net. Slightly larger
than usual because this batch includes several patches to tighten the
nf_tables control plane to reject inconsistent configuration:
1) Restrict NFTA_SET_POLICY to NFT_SET_POL_PERFORMANCE and
NFT_SET_POL_MEMORY.
2) Bail out if a nf_tables expression registers more than 16 netlink
attributes which is what struct nft_expr_info allows.
3) Bail out if NFT_EXPR_STATEFUL provides no .clone interface, remove
existing fallback to memcpy() when cloning which might accidentally
duplicate memory reference to the same object.
4) Fix br_netfilter interaction with neighbour layer. This requires
three preparation patches:
- Use nf_bridge_get_physinif() in nfnetlink_log
- Use nf_bridge_info_exists() to check in br_netfilter context
is available in nf_queue.
- Pass net to nf_bridge_get_physindev()
And finally, the fix which replaces physindev with physinif
in nf_bridge_info.
Patches from Pavel Tikhomirov.
5) Catch-all deactivation happens in the transaction, hence this
oneliner to check for the next generation. This bug uncovered after
the removal of the _BUSY bit, which happened in set elements back in
summer 2023.
6) Ensure set (total) key length size and concat field length description
is consistent, otherwise bail out.
7) Skip set element with the _DEAD flag on from the netlink dump path.
A tests occasionally shows that dump is mismatching because GC might
lose race to get rid of this element while a netlink dump is in
progress.
8) Reject NFT_SET_CONCAT for field_count < 1.
9) Use IP6_INC_STATS in ipvs to fix preemption BUG splat, patch

Following the same suggestions by Wolfram Sang as for the Dell Precision

Legacy class-based device auto-detection shouldn't be used in new code.
Therefore remove support in i2c-mux-reg as long as we don't have a

Now that the driver core can properly handle constant struct bus_type,
move the i2c_bus_type variable to be a constant structure as well, placing
it into read-only memory which can not be modified at runtime.
Note, the sound/soc/rockchip/rk3399_gru_sound.c also needed tweaking as
it decided to save off a pointer to a bus type for internal stuff, and
it was using the i2c_bus_type as well.

I originally restricted i2c_register_spd() to only support systems

a limited numbers of systems. It's been more than 3 years and it
seems to work just fine, so the time has come to lift this arbitrary
limitation.
The maximum number of memory slots which can be connected to a single
I2C segment is 8, so support that many SPD EEPROMs. Any system with
more than 8 memory slots would have either multiple SMBus channels
or SMBus multiplexing, so it would need dedicated care. We'll get to
that later as needed.

i2c_s3c_irq_nextbyte() is always executed till the end, properly
acknowledging the IRQ bits and no recursive calls to

While touching this, also fix finishing transfers in polling mode by

come back in a safer way next release cycle.
Included in here are:
- more driver core 'const' cleanups and fixes
- fw_devlink=rpm is now the default behavior
- kernfs tiny changes to remove some string functions
- cpu handling in the driver core is updated to work better on many
systems that add topologies and cpus after booting
- other minor changes and cleanups
All of the cpu handling patches have been acked by the respective
maintainers and are coming in here in one series. Everything has been

selftests: mlxsw: qos_pfc: Adjust the test to support 8 lanes
'qos_pfc' test checks PFC behavior. The idea is to limit the traffic
using a shaper somewhere in the flow of the packets. In this area, the
buffer is smaller than the buffer at the beginning of the flow, so it fills
up until there is no more space left. The test configures there PFC
which is supposed to notice that the headroom is filling up and send PFC
Xoff to indicate the transmitter to stop sending traffic for the priorities
sharing this PG.
The Xon/Xoff threshold is auto-configured and always equal to
2*(MTU rounded up to cell size). Even after sending the PFC Xoff packet,
traffic will keep arriving until the transmitter receives and processes
the PFC packet. This amount of traffic is known as the PFC delay allowance.
Currently the buffer for the delay traffic is configured as 100KB. The
MTU in the test is 10KB, therefore the threshold for Xoff is about 20KB.
This allows 80KB extra to be stored in this buffer.
8-lane ports use two buffers among which the configured buffer is split,
the Xoff threshold then applies to each buffer in parallel.
The test does not take into account the behavior of 8-lane ports, when the
ports are configured to 400Gbps with 8 lanes or 800Gbps with 8 lanes,
packets are dropped and the test fails.
Check if the relevant ports use 8 lanes, in such case double the size of
the buffer, as the headroom is split half-half.

mlxsw: spectrum_router: Register netdevice notifier before nexthop
If there are IPIP nexthops at the time when the driver is loaded (or the
devlink instance reloaded), the driver looks up the corresponding IPIP
entry. But IPIP entries are only created as a result of netdevice
notifications. Since the netdevice notifier is registered after the nexthop
notifier, mlxsw_sp_nexthop_type_init() never finds the IPIP entry,
registers the nexthop MLXSW_SP_NEXTHOP_TYPE_ETH, and fails to assign a CRIF
to the nexthop. Later on when the CRIF is necessary, the WARN_ON in
mlxsw_sp_nexthop_rif() triggers, causing the splat [1].
In order to fix the issue, reorder the netdevice notifier to be registered
before the nexthop one.

mlxsw: spectrum_acl_tcam: Fix stack corruption
When tc filters are first added to a net device, the corresponding local
port gets bound to an ACL group in the device. The group contains a list
of ACLs. In turn, each ACL points to a different TCAM region where the
filters are stored. During forwarding, the ACLs are sequentially
evaluated until a match is found.
One reason to place filters in different regions is when they are added
with decreasing priorities and in an alternating order so that two
consecutive filters can never fit in the same region because of their
key usage.
In Spectrum-2 and newer ASICs the firmware started to report that the
maximum number of ACLs in a group is more than 16, but the layout of the
register that configures ACL groups (PAGT) was not updated to account
for that. It is therefore possible to hit stack corruption [1] in the
rare case where more than 16 ACLs in a group are required.
Fix by limiting the maximum ACL group size to the minimum between what
the firmware reports and the maximum ACLs that fit in the PAGT register.
Add a test case to make sure the machine does not crash when this
condition is hit.

mlxsw: spectrum_acl_erp: Fix error flow of pool allocation failure
Lately, a bug was found when many TC filters are added - at some point,
several bugs are printed to dmesg [1] and the switch is crashed with
segmentation fault.
The issue starts when gen_pool_free() fails because of unexpected
behavior - a try to free memory which is already freed, this leads to BUG()
call which crashes the switch and makes many other bugs.
Trying to track down the unexpected behavior led to a bug in eRP code. The
function mlxsw_sp_acl_erp_table_alloc() gets a pointer to the allocated
index, sets the value and returns an error code. When gen_pool_alloc()
fails it returns address 0, we track it and return -ENOBUFS outside, BUT
the call for gen_pool_alloc() already override the index in erp_table
structure. This is a problem when such allocation is done as part of
table expansion. This is not a new table, which will not be used in case
of allocation failure. We try to expand eRP table and override the
current index (non-zero) with zero. Then, it leads to an unexpected
behavior when address 0 is freed twice. Note that address 0 is valid in
erp_table->base_index and indeed other tables use it.
gen_pool_alloc() fails in case that there is no space left in the
pre-allocated pool, in our case, the pool is limited to
ACL_MAX_ERPT_BANK_SIZE, which is read from hardware. When more than max
erp entries are required, we exceed the limit and return an error, this
error leads to "Failed to migrate vregion" print.
Fix this by changing erp_table->base_index only in case of a successful
allocation.
Add a test case for such a scenario. Without this fix it causes
segmentation fault:
$ TESTS="max_erp_entries_test" ./tc_flower.sh

loop: fix the the direct I/O support check when used on top of block devices
__loop_update_dio only checks the alignment requirement for block backed
file systems, but misses them for the case where the loop device is
created directly on top of another block device. Due to this creating
a loop device with default option plus the direct I/O flag on a > 512 byte
sector size file system will lead to incorrect I/O being submitted to the
lower block device and a lot of error from the lock layer. This can
be seen with xfstests generic/563.
Fix the code in __loop_update_dio by factoring the alignment check into
a helper, and calling that also for the struct block_device of a block
device inode.
Also remove the TODO comment talking about dynamically switching between
buffered and direct I/O, which is a would be a recipe for horrible
performance and occasional data loss.

Tighten up arg:ctx type enforcement
Follow up fixes for kernel-side and libbpf-side logic around handling arg:ctx
(__arg_ctx) tagged arguments of BPF global subprogs.
Patch #1 adds libbpf feature detection of kernel-side __arg_ctx support to
avoid unnecessary rewriting BTF types. With stricter kernel-side type
enforcement this is now mandatory to avoid problems with using `struct
bpf_user_pt_regs_t` instead of actual typedef. For __arg_ctx tagged arguments
verifier is now supporting either `bpf_user_pt_regs_t` typedef or resolves it
down to the actual struct (pt_regs/user_pt_regs/user_regs_struct), depending
on architecture), but for old kernels without __arg_ctx support it's more
backwards compatible for libbpf to use `struct bpf_user_pt_regs_t` rewrite
which will work on wider range of kernels. So feature detection prevent libbpf
accidentally breaking global subprogs on new kernels.
We also adjust selftests to do similar feature detection (much simpler, but
potentially breaking due to kernel source code refactoring, which is fine for
selftests), and skip tests expecting libbpf's BTF type rewrites.
Patch #2 is preparatory refactoring for patch #3 which adds type enforcement
for arg:ctx tagged global subprog args. See the patch for specifics.
Patch #4 adds many new cases to ensure type logic works as expected.
Finally, patch #5 adds a relevant subset of kernel-side type checks to
__arg_ctx cases that libbpf supports rewrite of. In libbpf's case, type
violations are reported as warnings and BTF rewrite is not performed, which
will eventually lead to BPF verifier complaining at program verification time.
Good care was taken to avoid conflicts between bpf and bpf-next tree (which
has few follow up refactorings in the same code area). Once trees converge
some of the code will be moved around a bit (and some will be deleted), but
with no change to functionality or general shape of the code.
v2->v3:
- support `bpf_user_pt_regs_t` typedef for KPROBE and PERF_EVENT (CI);
v1->v2:
- add user_pt_regs and user_regs_struct support for PERF_EVENT (CI);
- drop FEAT_ARG_CTX_TAG enum leftover from patch #1;
- fix warning about default: without break in the switch (CI).

libbpf: warn on unexpected __arg_ctx type when rewriting BTF
On kernel that don't support arg:ctx tag, before adjusting global
subprog BTF information to match kernel's expected canonical type names,
make sure that types used by user are meaningful, and if not, warn and
don't do BTF adjustments.
This is similar to checks that kernel performs, but narrower in scope,
as only a small subset of BPF program types can be accommodated by
libbpf using canonical type names.
Libbpf unconditionally allows `struct pt_regs *` for perf_event program
types, unlike kernel, which supports that conditionally on architecture.
This is done to keep things simple and not cause unnecessary false
positives. This seems like a minor and harmless deviation, which in
real-world programs will be caught by kernels with arg:ctx tag support
anyways. So KISS principle.
This logic is hard to test (especially on latest kernels), so manual
testing was performed instead. Libbpf emitted the following warning for
perf_event program with wrong context argument type:
libbpf: prog 'arg_tag_ctx_perf': subprog 'subprog_ctx_tag' arg#0 is expected to be of `struct bpf_perf_event_data *` type

bpf: enforce types for __arg_ctx-tagged arguments in global subprogs
Add enforcement of expected types for context arguments tagged with
arg:ctx (__arg_ctx) tag.
First, any program type will accept generic `void *` context type when
combined with __arg_ctx tag.
Besides accepting "canonical" struct names and `void *`, for a bunch of
program types for which program context is actually a named struct, we
allows a bunch of pragmatic exceptions to match real-world and expected
usage:
- for both kprobes and perf_event we allow `bpf_user_pt_regs_t *` as
canonical context argument type, where `bpf_user_pt_regs_t` is a
*typedef*, not a struct;
- for kprobes, we also always accept `struct pt_regs *`, as that's what
actually is passed as a context to any kprobe program;
- for perf_event, we resolve typedefs (unless it's `bpf_user_pt_regs_t`)
down to actual struct type and accept `struct pt_regs *`, or
`struct user_pt_regs *`, or `struct user_regs_struct *`, depending
on the actual struct type kernel architecture points `bpf_user_pt_regs_t`
typedef to; otherwise, canonical `struct bpf_perf_event_data *` is
expected;
- for raw_tp/raw_tp.w programs, `u64/long *` are accepted, as that's
what's expected with BPF_PROG() usage; otherwise, canonical
`struct bpf_raw_tracepoint_args *` is expected;
- tp_btf supports both `struct bpf_raw_tracepoint_args *` and `u64 *`
formats, both are coded as expections as tp_btf is actually a TRACING
program type, which has no canonical context type;
- iterator programs accept `struct bpf_iter__xxx *` structs, currently
with no further iterator-type specific enforcement;
- fentry/fexit/fmod_ret/lsm/struct_ops all accept `u64 *`;
- classic tracepoint programs, as well as syscall and freplace
programs allow any user-provided type.
In all other cases kernel will enforce exact match of struct name to
expected canonical type. And if user-provided type doesn't match that
expectation, verifier will emit helpful message with expected type name.
Note a bit unnatural way the check is done after processing all the
arguments. This is done to avoid conflict between bpf and bpf-next
trees. Once trees converge, a small follow up patch will place a simple
btf_validate_prog_ctx_type() check into a proper ARG_PTR_TO_CTX branch
(which bpf-next tree patch refactored already), removing duplicated
arg:ctx detection logic.

bpf: extract bpf_ctx_convert_map logic and make it more reusable
Refactor btf_get_prog_ctx_type() a bit to allow reuse of
bpf_ctx_convert_map logic in more than one places. Simplify interface by
returning btf_type instead of btf_member (field reference in BTF).
To do the above we need to touch and start untangling
btf_translate_to_vmlinux() implementation. We do the bare minimum to
not regress anything for btf_translate_to_vmlinux(), but its
implementation is very questionable for what it claims to be doing.
Mapping kfunc argument types to kernel corresponding types conceptually
is quite different from recognizing program context types. Fixing this
is out of scope for this change though.

libbpf: feature-detect arg:ctx tag support in kernel
Add feature detector of kernel-side arg:ctx (__arg_ctx) tag support. If
this is detected, libbpf will avoid doing any __arg_ctx-related BTF
rewriting and checks in favor of letting kernel handle this completely.
test_global_funcs/ctx_arg_rewrite subtest is adjusted to do the same
feature detection (albeit in much simpler, though round-about and
inefficient, way), and skip the tests. This is done to still be able to
execute this test on older kernels (like in libbpf CI).
Note, BPF token series ([0]) does a major refactor and code moving of
libbpf-internal feature detection "framework", so to avoid unnecessary
conflicts we keep newly added feature detection stand-alone with ad-hoc
result caching. Once things settle, there will be a small follow up to
re-integrate everything back and move code into its final place in
newly-added (by BPF token series) features.c file.
