Instead of just marking the buffer as having overflowed, fill it up as
much as we can. That will allow the overflow case to then return
whatever truncated result if it wants to.

'kvmalloc()' is a convenience function for people who want to do a
kmalloc() but fall back on vmalloc() if there aren't enough physically
contiguous pages, or if the allocation is larger than what kmalloc()
supports.
However, let's make sure it doesn't get _too_ easy to do crazy things
with it. In particular, don't allow big allocations that could be due
to integer overflow or underflow. So make sure the allocation size fits
in an 'int', to protect against trivial integer conversion issues.

Pull overlayfs update from Miklos Szeredi:
- Copy up immutable/append/sync/noatime attributes (Amir Goldstein)
- Improve performance by enabling RCU lookup.
- Misc fixes and improvements
The reason this touches so many files is that the ->get_acl() method now
gets a "bool rcu" argument. The ->get_acl() API was updated based on
comments from Al and Linus:

Pull erofs updates from Gao Xiang:
"In this cycle, direct I/O and fsdax support for uncompressed files are
now added in order to avoid double-caching for loop device and VM
container use cases. All uncompressed cases are now turned into iomap
infrastructure, which looks much simpler and cleaner.
In addition, fiemap support is added for both (un)compressed files by
using iomap infrastructure as well so end users can easily get file
distribution. We've also added chunk-based uncompressed files support
for data deduplication as the next step of VM container use cases.
Summary:
- support direct I/O for all uncompressed files
- support fsdax for non-tailpacking regular files
- use iomap infrastructure for all uncompressed cases
- support fiemap for both (un)compressed files
- introduce chunk-based files for chunk deduplication

"Preparatory work for the fscache rewrite that's being worked on and
fix some bugs. These include:
- Always select netfs stats when enabling fscache stats since they're

- Add a cookie debug ID that can be used in tracepoints instead of a

than in the netfs_read_request struct to make it more available.
- Use file_inode() in cachefiles rather than dereferencing
file->f_inode directly.
- Provide a procfile to display fscache cookies.
- Remove the fscache and cachefiles histogram procfiles.
- Remove the fscache object list procfile.
- Avoid using %p in fscache and cachefiles as the value is hashed and
not comparable to the register dump in an oops trace.
- Fix the cookie hash function to actually achieve useful dispersion.
- Fix fscache_cookie_put() so that it doesn't dereference the cookie

Due to a rebase damage, we lost the rtnl_lock() when the patch was
sent out. This causes an RTNL imbalance and failed assertions, due to
missing RTNL protection, for instance:
RTNL: assertion failed at net/wireless/reg.c (4025)

Pull xfs updates from Darrick Wong:
"There's a lot in this cycle.
Starting with bug fixes: To avoid livelocks between the logging code
and the quota code, we've disabled the ability of quotaoff to turn off
quota accounting. (Admins can still disable quota enforcement, but
truly turning off accounting requires a remount.) We've tried to do
this in a careful enough way that there shouldn't be any user visible
effects aside from quotaoff no longer randomly hanging the system.
We've also fixed some bugs in runtime log behavior that could trip up
log recovery if (otherwise unrelated) transactions manage to start and
commit concurrently; some bugs in the GETFSMAP ioctl where we would
incorrectly restrict the range of records output if the two xfs
devices are of different sizes; a bug that resulted in fallocate
funshare failing unnecessarily; and broken behavior in the xfs inode
cache when DONTCACHE is in play.
As for new features: we now batch inode inactivations in percpu
background threads, which sharply decreases frontend thread wait time
when performing file deletions and should improve overall directory
tree deletion times. This eliminates both the problem where closing an
unlinked file (especially on a frozen fs) can stall for a long time,
and should also ease complaints about direct reclaim bogging down on
unlinked file cleanup.
Starting with this release, we've enabled pipelining of the XFS log.
On workloads with high rates of metadata updates to different shards
of the filesystem, multiple threads can be used to format committed
log updates into log checkpoints.
Lastly, with this release, two new features have graduated to
supported status: inode btree counters (for faster mounts), and
support for dates beyond Y2038. Expect these to be enabled by default
in a future release of xfsprogs.
Summary:
- Fix a potential log livelock on busy filesystems when there's so
much work going on that we can't finish a quotaoff before filling
up the log by removing the ability to disable quota accounting.
- Introduce the ability to use per-CPU data structures in XFS so that
we can do a better job of maintaining CPU locality for certain
operations.
- Defer inode inactivation work to per-CPU lists, which will help us
batch that processing. Deletions of large sparse files will
*appear* to run faster, but all that means is that we've moved the
work to the backend.
- Drop the EXPERIMENTAL warnings from the y2038+ support and the
inode btree counters, since it's been nearly a year and no
complaints have come in.
- Remove more of our bespoke kmem* variants in favor of using the
standard Linux calls.
- Prepare for the addition of log incompat features in upcoming
cycles by actually adding code to support this.
- Small cleanups of the xattr code in preparation for landing support
for full logging of extended attribute updates in a future cycle.
- Replace the various log shutdown state and flag code all over xfs
with a single atomic bit flag.
- Fix a serious log recovery bug where log item replay can be skipped
based on the start lsn of a transaction even though the transaction
commit lsn is the key data point for that by enforcing start lsns
to appear in the log in the same order as commit lsns.
- Enable pipelining in the code that pushes log items to disk.
- Drop ->writepage.
- Fix some bugs in GETFSMAP where the last fsmap record reported for
a device could extend beyond the end of the device, and a separate
bug where query keys for one device could be applied to another.
- Don't let GETFSMAP query functions edit their input parameters.
- Small cleanups to the scrub code's handling of perag structures.
- Small cleanups to the incore inode tree walk code.
- Constify btree function parameters that aren't changed, so that
there will never again be confusion about range query functions
changing their input parameters.
- Standardize the format and names of tracepoint data attributes.
- Clean up all the mount state and feature flags to use wrapped
bitset functions instead of inconsistently open-coded flag checks.
- Fix some confusion between xfs_buf hash table key variable vs.
block number.
- Fix a mis-interaction with iomap where we reported shared delalloc
cow fork extents to iomap, which would cause the iomap unshare
operation to return IO errors unnecessarily.
- Fix DONTCACHE behavior"

Starting with following patch MIPS Malta is not able to boot:
| commit 79edff12060fe7772af08607eff50c0e2486c5ba
| Author: Rob Herring <robh@kernel.org>
| scripts/dtc: Update to upstream version v1.6.0-51-g183df9e9c2b9
The reason is the alignment test added to the fdt_ro_probe_(). To fix
this issue, we need to make sure that fdt_buf is aligned.
Since the dtc patch was designed to uncover potential issue, I handle
initial MIPS Malta patch as initial bug.

Pull ARM SoC updates from Arnd Bergmann:
"There are three noteworthy updates for 32-bit arm platforms this time:
- The Microchip SAMA7 family based on Cortex-A7 gets introduced, a
new cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5
based) SoCs.
- The ixp4xx platform (based on Intel XScale) is finally converted to
device tree, and all the old board files are getting removed now.
- The Cirrus Logic EP93xx platform loses support for the old
MaverickCrunch FPU. Support for compiling user space applications
was already removed in gcc-4.9, and the kernel support for old
applications could not be built with clang ias. After confirming
that there are no remaining users, removing this from the kernel
seemed better than adding support for unused features to clang.

Pull exit cleanups from Eric Biederman:
"In preparation of doing something about PTRACE_EVENT_EXIT I have
started cleaning up various pieces of code related to do_exit. Most of
that code I did not manage to get tested and reviewed before the merge
window opened but a handful of very useful cleanups are ready to be
merged.
The first change is simply the removal of the bdflush system call. The
code has now been disabled long enough that even the oldest userspace
working userspace setups anyone can find to test are fine with the
bdflush system call being removed.
Changing m68k fsp040_die to use force_sigsegv(SIGSEGV) instead of
calling do_exit directly is interesting only in that it is nearly the
most difficult of the incorrect uses of do_exit to remove.
The change to the seccomp code to simply send a signal instead of
calling do_coredump directly is a very nice little cleanup made
possible by realizing the existing signal sending helpers were missing
a little bit of functionality that is easy to provide"

I was debugging some crashes on parisc and I found out that there is a
crash possibility if a function using alloca is interrupted by a signal.
The reason for the crash is that the gcc alloca implementation leaves
garbage in the upper 32 bits of the sp register. This normally doesn't
matter (the upper bits are ignored because the PSW W-bit is clear),
however the signal delivery routine in the kernel uses full 64 bits of sp
and it fails with -EFAULT if the upper 32 bits are not zero.
I created this program that demonstrates the problem:
#include <stdlib.h>
#include <unistd.h>
#include <signal.h>
#include <alloca.h>
static __attribute__((noinline,noclone)) void aa(int *size)
{
void * volatile p = alloca(-*size);
while (1) ;
}
static void handler(int sig)
{
write(1, "signal delivered\n", 17);
_exit(0);
}
int main(void)
{
int size = -0x100;
signal(SIGALRM, handler);
alarm(1);
aa(&size);
}
If you compile it with optimizations, it will crash.
The "aa" function has this disassembly:
000106a0 <aa>:
106a0: 08 03 02 41 copy r3,r1
106a4: 08 1e 02 43 copy sp,r3

106b4: 0f 40 10 9c ldw 0(r26),ret0 ; ret0 = 0x00000000FFFFFF00

Commit 23243c1ace9f ("arch: use cross_compiling to check whether it is
a cross build or not") broke 64-bit parisc builds on 32-bit parisc
systems.
Helge mentioned:
- 64-bit parisc userspace is not supported yet [1]
- hppa gcc does not support "-m64" flag [2]
That means, parisc developers working on a 32-bit parisc machine need
to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit
parisc kernel.
After the offending commit, gcc is used in such a case because
both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is
unset.
A correct way is to introduce ARCH=parisc64 because building the 64-bit
parisc kernel on a 32-bit parisc system is not exactly a native build,
but rather a semi-cross build.

This patch makes a small simplification to the code in
hid_submit_ctrl(). The test for maxpacket being > 0 is unnecessary,
because endpoint 0 always has a maxpacket value which is >= 8.
Furthermore, endpoint 0's maxpacket value is always a power of 2, so
instead of open-coding the round-to-next-multiple computation we can
call the optimized round_up() routine.

(The warning message is a little difficult to understand. It means
that the control request claims to be for an IN transfer but this
contradicts the USB spec, which requires 0-length control transfers
always to be in the OUT direction.)
Now, a zero-length report isn't good for anything and there's no
reason for a device to have one, but the fuzzer likes to pick out
these weird edge cases. In the future, perhaps we will decide to
reject 0-length reports at probe time. For now, the simplest approach
for avoiding these warnings is to pretend that the report actually has
length 1.

[patch description by Alan Stern]
Commit 7652dd2c5cb7 ("USB: core: Check buffer length matches wLength
for control transfers") causes control URB submissions to fail if the
transfer_buffer_length value disagrees with the setup packet's wLength
valuel. Unfortunately, it turns out that the usbhid can trigger this
failure mode when it submits a control request for an input report: It
pads the transfer buffer size to a multiple of the maxpacket value but
does not increase wLength correspondingly.
These failures have caused problems for people using an APS UPC, in
the form of a flood of log messages resembling:
hid-generic 0003:051D:0002.0002: control queue full
This patch fixes the problem by setting the wLength value equal to the
padded transfer_buffer_length value in hid_submit_ctrl(). As a nice
bonus, the code which stores the transfer_buffer_length value is now
shared between the two branches of an "if" statement, so it can be
de-duplicated.

After commit 342f43af70db ("iscsi_ibft: fix crash due to KASLR physical
memory remapping") x86_64_defconfig shows the following errors:
arch/x86/kernel/setup.c: In function ‘setup_arch’:
arch/x86/kernel/setup.c:916:13: error: implicit declaration of function ‘acpi_mps_check’ [-Werror=implicit-function-declaration]
916 | if (acpi_mps_check()) {
| ^~~~~~~~~~~~~~
arch/x86/kernel/setup.c:1110:9: error: implicit declaration of function ‘acpi_table_upgrade’ [-Werror=implicit-function-declaration]
1110 | acpi_table_upgrade();
| ^~~~~~~~~~~~~~~~~~
[... more acpi noise ...]
acpi.h was being implicitly included from iscsi_ibft.h in this
configuration so the removal of that header means these functions have
no definition or declaration.
In most other configurations, <linux/acpi.h> continued to be included
through at least <linux/tboot.h> if CONFIG_INTEL_TXT was enabled, and
there were probably other implicit include paths too.
Add acpi.h explicitly so there is no more error, and so that we don't
continue to depend on these unreliable implicit include paths.
