m68knommu: fix missing LCD splash screen data initializer
|

Prepare input updates for 5.14 merge window.
|

Even though we validate user-provided inputs we then traverse past
validated data when applying the new map. The issue was originally
discovered by Murray McAllister with this simple POC (if the following
is executed by an unprivileged user it will instantly panic the system):
int main(void) {
int fd, ret;
unsigned int buffer[10000];
fd = open("/dev/input/js0", O_RDONLY);
if (fd == -1)
printf("Error opening file\n");
ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer);
printf("%d\n", ret);
}
The solution is to traverse internal buffer which is guaranteed to only
contain valid date when constructing the map.
Fixes: 182d679b2298 ("Input: joydev - prevent potential read overflow in ioctl")
Fixes: 999b874f4aa3 ("Input: joydev - validate axis/button maps before clobbering current ones")

This warning was there to catch any architectures that still use
CONFIG_SET_FS, and that would mis-use iov_iter_init() for anything that
wasn't a proper user space pointer. So that
WARN_ON_ONCE(uaccess_kernel());
makes perfect conceptual sense: you really shouldn't use a kernel
pointer with set_fs(KERNEL_DS) and then pass it to iov_iter_init().
HOWEVER.
Guenter Roeck reports that this warning actually triggers in no-mmu
configurations of both ARM and m68k. And the reason isn't that they
pass in a kernel pointer under set_fs(KERNEL_DS) at all: the reason is
that in those configurations, "uaccess_kernel()" is simply not reliable.
Those no-mmu setups set USER_DS and KERNEL_DS to the same values, so you
can't test for the difference.
In particular, the no-mmu case for ARM does
#define USER_DS KERNEL_DS
#define uaccess_kernel() (true)
so USER_DS and KERNEL_DS have the same value, and uaccess_kernel() is
always trivially true.
The m68k case is slightly different and not quite as obvious. It does
(spread out over multiple header files just to be extra exciting:
asm/processor.h, asm/segment.h and asm-generic/uaccess.h):
#define TASK_SIZE (0xFFFFFFFFUL)
#define USER_DS MAKE_MM_SEG(TASK_SIZE)
#define KERNEL_DS MAKE_MM_SEG(~0UL)
#define get_fs() (current_thread_info()->addr_limit)
#define uaccess_kernel() (get_fs().seg == KERNEL_DS.seg)
but the end result is the same: uaccess_kernel() will always be true,
because USER_DS and KERNEL_DS end up having the same value, even if that
value is defined differently.
This is very arguably a misfeature in those implementations, but in the
end we don't really care. All modern architectures have gotten rid of
set_fs() already, and generic kernel code never uses it. And while the
sanity check was a nice idea, an architecture would have to go the extra
mile to actually break this.
So this well-intentioned warning isn't really all that likely to find
anything but these known false positives, and as such just isn't worth
maintaining.

Pull memblock updates from Mike Rapoport:
"Fix arm crashes caused by holes in the memory map.
The coordination between freeing of unused memory map, pfn_valid() and
core mm assumptions about validity of the memory map in various ranges
was not designed for complex layouts of the physical memory with a lot
of holes all over the place.
Kefen Wang reported crashes in move_freepages() on a system with the
following memory layout [1]:
node 0: [mem 0x0000000080a00000-0x00000000855fffff]
node 0: [mem 0x0000000086a00000-0x0000000087dfffff]
node 0: [mem 0x000000008bd00000-0x000000008c4fffff]
node 0: [mem 0x000000008e300000-0x000000008ecfffff]
node 0: [mem 0x0000000090d00000-0x00000000bfffffff]
node 0: [mem 0x00000000cc000000-0x00000000dc9fffff]
node 0: [mem 0x00000000de700000-0x00000000de9fffff]
node 0: [mem 0x00000000e0800000-0x00000000e0bfffff]

node 0: [mem 0x00000000fda00000-0x00000000ffffefff]
These crashes can be mitigated by enabling CONFIG_HOLES_IN_ZONE on ARM
and essentially turning pfn_valid_within() to pfn_valid() instead of
having it hardwired to 1 on that architecture, but this would require
to keep CONFIG_HOLES_IN_ZONE solely for this purpose.
A cleaner approach is to update ARM's implementation of pfn_valid() to
take into accounting rounding of the freed memory map to pageblock
boundaries and make sure it returns true for PFNs that have memory map
entries even if there is no physical memory backing those PFNs"

Pull CXL (Compute Express Link) updates from Dan Williams:
"This subsystem is still in the build-out phase as the bulk of the
update is improvements to enumeration and fleshing out the device
model. In terms of new features, more mailbox commands have been added
to the allowed-list in support of persistent memory provisioning
support targeting v5.15.
The critical update from an enumeration perspective is support for the
CXL Fixed Memory Window Structure that indicates to Linux which system
physical address ranges decode to the CXL Host Bridges in the system.
This allows the driver to detect which address ranges have been mapped
by firmware and what address ranges are available for future hotplug.
So, again, mostly skeleton this round, with more meat targeting v5.15.
Summary:
- Add support for the CXL Fixed Memory Window Structure, a recent
extension of the ACPI CEDT (CXL Early Discovery Table)
- Add infrastructure for component registers
- Add HDM (Host-managed device memory) decoder definitions
- Define a device model for an HDM decoder tree
- Bridge CXL persistent memory capabilities to an NVDIMM bus /
device-model
- Switch to fine grained mapping of CXL MMIO registers to allow
different drivers / system software to own individual register
blocks
- Enable media provisioning commands, and publish the label storage
area size in sysfs
- Miscellaneous cleanups and fixes"

Commit d2bcbeab4200 ("scsi: blkcg: Add app identifier support for
blkcg") introduced an FC_APPID config option under SCSI. However, the
added config option is not used anywhere. Simply remove it.
The block layer BLK_CGROUP_FC_APPID config option is what actually
controls whether the application ID code should be built or not. Make
this option dependent on NVMe over FC since that is currently the only
transport which supports the capability.

- Have hwlat tracer handle hotplug CPUs
- New tracer: osnoise, that detects latency caused by interrupts,
softirqs and scheduling of other tasks.
- Added timerlat tracer that creates a thread and measures in detail
what sources of latency it has for wake ups.
- Removed the "success" field of the sched_wakeup trace event. This has
been hardcoded as "1" since 2015, no tooling should be looking at it
now. If one exists, we can revert this commit, fix that tool and try
to remove it again in the future.
- tgid mapping fixed to handle more than PID_MAX_DEFAULT pids/tgids.
- New boot command line option "tp_printk_stop", as tp_printk causes
trace events to write to console. When user space starts, this can
easily live lock the system. Having a boot option to stop just after
boot up is useful to prevent that from happening.

This reverts commit 9ce650a75a3b262c90789b42aedee8fc2ee04d53.
This commit causes watchdog lockups on my machine, and while I have no
idea what the cause is, it bisected right to this commit, and reverting
the change promptly fixes it.
At least occasionally one of the watchdog call traces was
Call Trace:
_raw_spin_lock_irqsave+0x35/0x40
snd_pcm_period_elapsed+0x1b/0xa0 [snd_pcm]
snd_usb_endpoint_start+0x1a0/0x3c0 [snd_usb_audio]
start_endpoints+0x23/0x90 [snd_usb_audio]
snd_usb_substream_playback_trigger+0x7b/0x1a0 [snd_usb_audio]
snd_pcm_common_ioctl+0x1c44/0x2360 [snd_pcm]
snd_pcm_ioctl+0x2e/0x40 [snd_pcm]
__se_sys_ioctl+0x72/0xc0
do_syscall_64+0x4c/0xa0
entry_SYSCALL_64_after_hwframe+0x44/0xae
so presumably it's a locking error on that substream spinlock that
snd_pcm_period_elapsed() takes. But at this point I just want to have a
working system so that I can continue the merge window work tomorrow.

Pull sound updates from Takashi Iwai:
"As the diffstat scatters over the tree, we've got many tree-wide small
changes, but also got quite a few intrusive changes in the core side.
The only ABI-visible core change is the new rawmidi framing mode
support while others are kernel-internal, mostly code refactoring
and/or nice improvements.
Here are some highlights:
Core:
- A new framing access mode for rawmidi to get timestamps
- Cleanup / refactoring of buffer memory management helper code
- Support for automatic negotiation of ASoC DAI formats
- Revival of software suspend for PCM and control core, as a
preliminary work for PCI BAR rescan support
ASoC:
- Accessory detection support for several Qualcomm parts
- Support for IEC958 control with hdmi-codec
- Merging of Tegra machine drivers into a single driver
- Support for AmLogic SM1 TOACODEC, Intel AlderLake-M, several NXP
i.MX8 variants, NXP TFA1 and TDF9897, Rockchip RK817, Qualcomm
Quinary MI2S, Texas Instruments TAS2505

Pull xfs updates from Darrick Wong:
"Most of the work this cycle has been on refactoring various parts of
the codebase. The biggest non-cleanup changes are (1) reducing the
number of cache flushes sent when writing the log; (2) a substantial
number of log recovery fixes; and (3) I started accepting pull
requests from contributors if the commits in their branches match
what's been sent to the list.
For a week or so I /had/ staged a major cleanup of the logging code
from Dave Chinner, but it exposed so many lurking bugs in other parts
of the logging and log recovery code that I decided to defer that
patchset until we can address those latent bugs.
Larger cleanups this time include walking the incore inode cache (me)
and rework of the extended attribute code (Allison) to prepare it for
adding logged xattr updates (and directory tree parent pointers) in
future releases.
Summary:
- Refactor the buffer cache to use bulk page allocation
- Convert agnumber-based AG iteration to walk per-AG structures
- Clean up some unit conversions and other code warts
- Reduce spinlock contention in the directio fastpath
- Collapse all the inode cache walks into a single function
- Remove indirect function calls from the inode cache walk code
- Dramatically reduce the number of cache flushes sent when writing
log buffers
- Preserve inode sickness reports for longer
- Rename xfs_eofblocks since it controls inode cache walks
- Refactor the extended attribute code to prepare it for the addition
of log intent items to make xattrs fully transactional
- A few fixes to earlier large patchsets
- Log recovery fixes so that we don't accidentally mark the log clean
when log intent recovery fails
- Fix some latent SOB errors
- Clean up shutdown messages that get logged to dmesg
- Fix a regression in the online shrink code
- Fix a UAF in the buffer logging code if the fs goes offline
- Fix uninitialized error variables
- Fix a UAF in the CIL when commited log item callbacks race with a
shutdown
- Fix a bug where the CIL could hang trying to push part of the log
ring buffer that hasn't been filled yet"

Pull asm/unaligned.h unification from Arnd Bergmann:
"Unify asm/unaligned.h around struct helper
The get_unaligned()/put_unaligned() helpers are traditionally
architecture specific, with the two main variants being the
"access-ok.h" version that assumes unaligned pointer accesses always
work on a particular architecture, and the "le-struct.h" version that
casts the data to a byte aligned type before dereferencing, for
architectures that cannot always do unaligned accesses in hardware.
Based on the discussion linked below, it appears that the access-ok
version is not realiable on any architecture, but the struct version
probably has no downsides. This series changes the code to use the
same implementation on all architectures, addressing the few
exceptions separately"

When an eMMC device is being run in HS400 mode, any access to the
RPMB device will cause the error message "mmc1: Invalid UHS-I mode
selected". This happens as a result of tuning being disabled before
RPMB access and then re-enabled after the RPMB access is complete.
When tuning is re-enabled, the system has to switch from HS400
to HS200 to do the tuning and then back to HS400. As part of
sequence to switch from HS400 to HS200 the system is temporarily
put into HS mode. When switching to HS mode, sdhci_get_preset_value()
is called and does not have support for HS mode and prints the warning
message and returns the preset for SDR12. The fix is to add support
for MMC and SD HS modes to sdhci_get_preset_value().
This can be reproduced on any system running eMMC in HS400 mode
(not HS400ES) by using the "mmc" utility to run the following
command: "mmc rpmb read-counter /dev/mmcblk0rpmb".

Prior to commit 1538d82f4647 ("i2c: mpc: Interrupt driven transfer") the
old interrupt handler would reread MPC_I2C_SR after checking the CSR_MIF
bit. When the driver was re-written this was removed as it seemed
unnecessary. However as it turns out this is necessary for i2c devices
which do clock stretching otherwise we end up thinking the bus is still
busy when processing the interrupt.

Pull percpu updates from Dennis Zhou:
- percpu chunk depopulation - depopulate backing pages for chunks with
empty pages when we exceed a global threshold without those pages.
This lets us reclaim a portion of memory that would previously be
lost until the full chunk would be freed (possibly never).
- memcg accounting cleanup - previously separate chunks were managed
for normal allocations and __GFP_ACCOUNT allocations. These are now
consolidated which cleans up the code quite a bit.
- a few misc clean ups for clang warnings
