module: Fix prefix for module.sig_enforce module param
Commit 2c85ee92a950 ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files. A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.
This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.
So, set the prefix back to "module.".

At slot 0, an internal node with 2 leaves could not be folded into the
node, because there was only one available slot (slot 0). Thus, the
internal node was retained. At slot 1, the node had one leaf, and was
able to be folded in successfully. The remaining nodes had no leaves,
and so were removed. By the end of the compression stage, there were 14
free slots, and only 3 leaf nodes. The tree was ascended and then its
parent node was compressed. When this node was seen, it could not be
folded, due to the internal node it contained.
The invariant for compression in this function is: whenever
nr_leaves_on_branch < ASSOC_ARRAY_FAN_OUT, the node should contain all
leaf nodes. The compression step currently cannot guarantee this, given
the corner case shown above.
To fix this issue, retry compression whenever we have retained a node,
and yet nr_leaves_on_branch < ASSOC_ARRAY_FAN_OUT. This second
compression will then allow the node in slot 1 to be folded in,
satisfying the invariant. Below is the output of the reproducer once the
fix is applied:

afs: Fix infinite loop found by xfstest generic/676
In AFS, a directory is handled as a file that the client downloads and
parses locally for the purposes of performing lookup and getdents
operations. The in-kernel afs filesystem has a number of functions that
do this.
A directory file is arranged as a series of 2K blocks divided into
32-byte slots, where a directory entry occupies one or more slots, plus
each block starts with one or more metadata blocks.
When parsing a block, if the last slots are occupied by a dirent that
occupies more than a single slot and the file position points at a slot
that's not the initial one, the logic in afs_dir_iterate_block() that
skips over it won't advance the file pointer to the end of it. This
will cause an infinite loop in getdents() as it will keep retrying that
block and failing to advance beyond the final entry.
Fix this by advancing the file pointer if the next entry will be beyond
it when we skip a block.
This was found by the generic/676 xfstest but can also be triggered with
something like:

"In this round, we've refactored the existing atomic write support
implemented by in-memory operations to have storing data in disk
temporarily, which can give us a benefit to accept more atomic writes.
At the same time, we removed the existing volatile write support.
We've also revisited the file pinning and GC flows and found some
corner cases which contributeed abnormal system behaviours.
As usual, there're several minor code refactoring for readability,
sanity check, and clean ups.
Enhancements:
- allow compression for mmap files in compress_mode=user
- kill volatile write support
- change the current atomic write way
- give priority to select unpinned section for foreground GC
- introduce data read/write showing path info
- remove unnecessary f2fs_lock_op in f2fs_new_inode
Bug fixes:
- fix the file pinning flow during checkpoint=disable and GCs
- fix foreground and background GCs to select the right victims and
get free sections on time
- fix GC flags on defragmenting pages
- avoid an infinite loop to flush node pages
- fix fallocate to use file_modified to update permissions

dm table: fix dm_table_supports_poll to return false if no data devices
It was reported that the "generic/250" test in xfstests (which uses
the dm-error target) demonstrates a regression where the kernel
crashes in bioset_exit().
Since commit 3345f71f1e92 ("dm: conditionally enable
BIOSET_PERCPU_CACHE for dm_io bioset") the bioset_init() for the dm_io
bioset will setup the bioset's per-cpu alloc cache if all devices have
QUEUE_FLAG_POLL set.
But there was an bug where a target that doesn't have any data devices
(and that doesn't even set the .iterate_devices dm target callback)
will incorrectly return true from dm_table_supports_poll().
Fix this by updating dm_table_supports_poll() to follow dm-table.c's
well-worn pattern for testing that _all_ targets in a DM table do in
fact have underlying devices that set QUEUE_FLAG_POLL.
NOTE: An additional block fix is still needed so that
bio_alloc_cache_destroy() clears the bioset's ->cache member.
Otherwise, a DM device's table reload that transitions the DM device's
bioset from using a per-cpu alloc cache to _not_ using one will result
in bioset_exit() crashing in bio_alloc_cache_destroy() because dm's
dm_io bioset ("io_bs") was left with a stale ->cache member.

Merge branch 'guilt/xfs-5.19-larp-cleanups' into xfs-5.19-for-next
This series contains a two key cleanups for the new LARP code. Most
of it is refactoring and tweaking the code that creates kernel log
messages about enabling and disabling features -- we should be
warning about LARP being turned on once per mount, instead of once
per insmod cycle; we shouldn't be spamming the logs so aggressively
about turning *off* log incompat features.
The second part of the series refactors the LARP code responsible
for getting (and releasing) permission to use xattr log items. The
implementation code doesn't belong in xfs_log.c, and calls to
logging functions don't belong in libxfs -- they really should be
done by the VFS implementation functions before they start calling
into libraries.

erofs: leave compressed inodes unsupported in fscache mode for now
erofs over fscache doesn't support the compressed layout yet. It will
cause NULL crash if there are compressed inodes contained when working
in fscache mode.
So far in the erofs based container image distribution scenarios
(RAFS v6), the compressed RAFS v6 images are downloaded and then
decompressed on demand as an uncompressed erofs image. Then the erofs
image is mounted in fscache mode for containers to use. IOWs, currently
compressed data is decompressed on the userspace side instead and
uncompressed erofs images will be finally cached.
The fscache support for the compressed layout is still under
development and it will be used for runtime decompression feature.
Anyway, to avoid the potential crash, let's leave the compressed inodes
unsupported in fscache mode until we support it later.

drm: fix EDID struct for old ARM OABI format
When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc
will force alignment of all structures and unions to a word boundary
(see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX"
option if you're a gcc person), even when the members of said structures
do not want or need said alignment.
This completely messes up the structure alignment of 'struct edid' on
those targets, because even though all the embedded structures are
marked with "__attribute__((packed))", the unions that contain them are
not.
This was exposed by commit 48199ff417e5 ("drm/edid: add EDID block count
and size helpers"), but the bug is pre-existing. That commit just made
the structure layout problem cause a build failure due to the addition
of the
BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH);
sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data().
This legacy union alignment should probably not be used in the first
place, but we can fix the layout by adding the packed attribute to the
union entries even when each member is already packed and it shouldn't
matter in a sane build environment.
You can see this issue with a trivial test program:

video: fbdev: vesafb: Fix a use-after-free due early fb_info cleanup
Commit bdffc31d4a3b ("fbdev: vesafb: Cleanup fb_info in .fb_destroy rather
than .remove") fixed a use-after-free error due the vesafb driver freeing
the fb_info in the .remove handler instead of doing it in .fb_destroy.
This can happen if the .fb_destroy callback is executed after the .remove
callback, since the former tries to access a pointer freed by the latter.
But that change didn't take into account that another possible scenario is
that .fb_destroy is called before the .remove callback. For example, if no
process has the fbdev chardev opened by the time the driver is removed.
If that's the case, fb_info will be freed when unregister_framebuffer() is
called, making the fb_info pointer accessed in vesafb_remove() after that
to no longer be valid.
To prevent that, move the expression containing the info->par to happen
before the unregister_framebuffer() function call.

We could attempt to fix this by listing the dependencies piecemeal, but
it's not as obvious as it looks: drivers like caam use this macro in
headers even if there's no .o compiled in that makes use of it. So
actually fixing this might require a bit more of a comprehensive
approach, rather than whack-a-mole with hunting down which drivers use
which headers which use this macro.
Therefore, this commit just reverts the change, and maybe the problem
can be visited on the next rainy day.

ftrace: Add FTRACE_MCOUNT_MAX_OFFSET to avoid adding weak function
If an unused weak function was traced, it's call to fentry will still
exist, which gets added into the __mcount_loc table. Ftrace will use
kallsyms to retrieve the name for each location in __mcount_loc to display
it in the available_filter_functions and used to enable functions via the
name matching in set_ftrace_filter/notrace. Enabling these functions do
nothing but enable an unused call to ftrace_caller. If a traced weak
function is overridden, the symbol of the function would be used for it,
which will either created duplicate names, or if the previous function was
not traced, it would be incorrectly be listed in available_filter_functions
as a function that can be traced.
This became an issue with BPF[1] as there are tooling that enables the
direct callers via ftrace but then checks to see if the functions were
actually enabled. The case of one function that was marked notrace, but
was followed by an unused weak function that was traced. The unused
function's call to fentry was added to the __mcount_loc section, and
kallsyms retrieved the untraced function's symbol as the weak function was
overridden. Since the untraced function would not get traced, the BPF
check would detect this and fail.
The real fix would be to fix kallsyms to not show addresses of weak
functions as the function before it. But that would require adding code in
the build to add function size to kallsyms so that it can know when the
function ends instead of just using the start of the next known symbol.
In the mean time, this is a work around. Add a FTRACE_MCOUNT_MAX_OFFSET
macro that if defined, ftrace will ignore any function that has its call
to fentry/mcount that has an offset from the symbol that is greater than
FTRACE_MCOUNT_MAX_OFFSET.
If CONFIG_HAVE_FENTRY is defined for x86, define FTRACE_MCOUNT_MAX_OFFSET
to zero (unless IBT is enabled), which will have ftrace ignore all locations
that are not at the start of the function (or one after the ENDBR
instruction).
A worker thread is added at boot up to scan all the ftrace record entries,
and will mark any that fail the FTRACE_MCOUNT_MAX_OFFSET test as disabled.
They will still appear in the available_filter_functions file as:
__ftrace_invalid_address___<invalid-offset>
(showing the offset that caused it to be invalid).
This is required for tools that use libtracefs (like trace-cmd does) that
scan the available_filter_functions and enable set_ftrace_filter and
set_ftrace_notrace using indexes of the function listed in the file (this
is a speedup, as enabling thousands of files via names is an O(n^2)
operation and can take minutes to complete, where the indexing takes less
than a second).
The invalid functions cannot be removed from available_filter_functions as
the names there correspond to the ftrace records in the array that manages
them (and the indexing depends on this).

pcmcia: Use platform_get_irq() to get the interrupt
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.
platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.
It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

"Compute Express Link (CXL) updates for this cycle.
The highlight is new driver-core infrastructure and CXL subsystem
changes for allowing lockdep to validate device_lock() usage. Thanks
to PeterZ for setting me straight on the current capabilities of the
lockdep API, and Greg acked it as well.
On the CXL ACPI side this update adds support for CXL _OSC so that
platform firmware knows that it is safe to still grant Linux native
control of PCIe hotplug and error handling in the presence of CXL
devices. A circular dependency problem was discovered between suspend
and CXL memory for cases where the suspend image might be stored in
CXL memory where that image also contains the PCI register state to
restore to re-enable the device. Disable suspend for now until an
architecture is defined to clarify that conflict.
Lastly a collection of reworks, fixes, and cleanups to the CXL
subsystem where support for snooping mailbox commands and properly
handling the "mem_enable" flow are the highlights.
Summary:
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously
hidden behind the 'lockdep no validate' policy.
- Add CXL _OSC support for claiming native control of CXL hotplug and
error handling.
- Disable suspend in the presence of CXL memory unless and until a
protocol is identified for restoring PCI device context from memory
hosted on CXL PCI devices.
- Add support for snooping CXL mailbox commands to protect against
inopportune changes, like set-partition with the 'immediate' flag
set.
- Rework how the driver detects legacy CXL 1.1 configurations (CXL
DVSEC / 'mem_enable') before enabling new CXL 2.0 decode
configurations (CXL HDM Capability).

There's a single patch to the core clk framework that simplifies a
runtime PM call. Otherwise the majority of the diff falls to a few SoC

remapping errors when MSI-X remapping is disabled (Nirmal Patel)
- Revert VMD workaround that kept MSI-X remapping enabled when IOMMU
remapping was enabled (Nirmal Patel)
Marvell MVEBU PCIe controller driver:
- Add of_pci_get_slot_power_limit() to parse the
'slot-power-limit-milliwatt' DT property (Pali Rohár)

- Reset PHY and MAC at probe time (AngeloGioacchino Del Regno)
Microchip PolarFlare PCIe controller driver:
- Add chained_irq_enter()/chained_irq_exit() calls to mc_handle_msi()
and mc_handle_intx() to avoid lost interrupts (Conor Dooley)
- Fix interrupt handling race (Daire McNamara)
NVIDIA Tegra194 PCIe controller driver:
- Drop tegra194 MSI register save/restore, which is unnecessary since
the DWC core does it (Jisheng Zhang)
Qualcomm PCIe controller driver:
- Add SM8150 SoC DT binding and support (Bhupesh Sharma)
- Fix pipe clock imbalance (Johan Hovold)
- Fix runtime PM imbalance on probe errors (Johan Hovold)
- Fix PHY init imbalance on probe errors (Johan Hovold)
- Convert DT binding to YAML (Dmitry Baryshkov)
- Update DT binding to show that resets aren't required for
MSM8996/APQ8096 platforms (Dmitry Baryshkov)
- Add explicit register names per chipset in DT binding (Dmitry
Baryshkov)
- Add sc7280-specific clock and reset definitions to DT binding
(Dmitry Baryshkov)
Rockchip PCIe controller driver:
- Fix bitmap size when searching for free outbound region (Dan
Carpenter)
Rockchip DesignWare PCIe controller driver:
- Remove "snps,dw-pcie" from rockchip-dwc DT "compatible" property
because it's not fully compatible with rockchip (Peter Geis)
- Reset rockchip-dwc controller at probe (Peter Geis)
- Add rockchip-dwc INTx support (Peter Geis)
Synopsys DesignWare PCIe controller driver:
- Return error instead of success if DMA mapping of MSI area fails
(Jiantao Zhang)
Miscellaneous:
- Change pci_set_dma_mask() documentation references to
dma_set_mask() (Alex Williamson)"
