Syzbot reported that in rename directory operation on broken directory on
nilfs2, __block_write_begin_int() called to prepare block write may fail
BUG_ON check for access exceeding the folio/page size.
This is because nilfs_dotdot(), which gets parent directory reference
entry ("..") of the directory to be moved or renamed, does not check
consistency enough, and may return location exceeding folio/page size for
broken directories.
Fix this issue by checking required directory entries ("." and "..") in
the first chunk of the directory in nilfs_dotdot().

While investigating HVO for THPs [1], it turns out that speculative PFN
walkers like compaction can race with vmemmap modifications, e.g.,
CPU 1 (vmemmap modifier) CPU 2 (speculative PFN walker)
------------------------------- ------------------------------
Allocates an LRU folio page1
Sees page1
Frees page1
Allocates a hugeTLB folio page2
(page1 being a tail of page2)
Updates vmemmap mapping page1
get_page_unless_zero(page1)
Even though page1->_refcount is zero after HVO, get_page_unless_zero() can
still try to modify this read-only field, resulting in a crash.
An independent report [2] confirmed this race.
There are two discussed approaches to fix this race:
1. Make RO vmemmap RW so that get_page_unless_zero() can fail without
triggering a PF.
2. Use RCU to make sure get_page_unless_zero() either sees zero
page->_refcount through the old vmemmap or non-zero page->_refcount
through the new one.
The second approach is preferred here because:
1. It can prevent illegal modifications to struct page[] that has been
HVO'ed;
2. It can be generalized, in a way similar to ZERO_PAGE(), to fix
similar races in other places, e.g., arch_remove_memory() on x86
[3], which frees vmemmap mapping offlined struct page[].
While adding synchronize_rcu(), the goal is to be surgical, rather than
optimized. Specifically, calls to synchronize_rcu() on the error handling
paths can be coalesced, but it is not done for the sake of Simplicity:
noticeably, this fix removes ~50% more lines than it adds.
According to the hugetlb_optimize_vmemmap section in
Documentation/admin-guide/sysctl/vm.rst, enabling HVO makes allocating or
freeing hugeTLB pages "~2x slower than before". Having synchronize_rcu()
on top makes those operations even worse, and this also affects the user
interface /proc/sys/vm/nr_overcommit_hugepages.
This is *very* hard to trigger:
1. Most hugeTLB use cases I know of are static, i.e., reserved at
boot time, because allocating at runtime is not reliable at all.
2. On top of that, someone has to be very unlucky to get tripped
over above, because the race window is so small -- I wasn't able to
trigger it with a stress testing that does nothing but that (with
THPs though).

syzbot detects that cachestat() is flushing stats, which can sleep, in its
RCU read section (see [1]). This is done in the workingset_test_recent()
step (which checks if the folio's eviction is recent).
Move the stat flushing step to before the RCU read section of cachestat,
and skip stat flushing during the recency check.

In page_cache_ra_order(), the maximal order of the page cache to be
allocated shouldn't be larger than MAX_PAGECACHE_ORDER. Otherwise, it's
possible the large page cache can't be supported by xarray when the
corresponding xarray entry is split.
For example, HPAGE_PMD_ORDER is 13 on ARM64 when the base page size is
64KB. The PMD-sized page cache can't be supported by xarray.

DAMON keeps the number of regions under max_nr_regions by skipping regions
split operations when doing so can make the number higher than the limit.
It works well for preventing violation of the limit. But, if somehow the
violation happens, it cannot recovery well depending on the situation. In
detail, if the real number of regions having different access pattern is
higher than the limit, the mechanism cannot reduce the number below the
limit. In such a case, the system could suffer from high monitoring
overhead of DAMON.
The violation can actually happen. For an example, the user could reduce
max_nr_regions while DAMON is running, to be lower than the current number
of regions. Fix the problem by repeating the merge operations with
increasing aggressiveness in kdamond_merge_regions() for the case, until
the limit is met.

The problem is that there are systems where cpu_possible_mask has gaps
between set CPUs, for example SPARC. In this scenario addr_to_vb_xa()
hash function can return an index which accesses to not-possible and not
setup CPU area using per_cpu() macro. This results in an oops on SPARC.
A per-cpu vmap_block_queue is also used as hash table, incorrectly
assuming the cpu_possible_mask has no gaps. Fix it by adjusting an index
to a next possible CPU.

If the bitmap block that manages the inode allocation status is corrupted,
nilfs_ifile_create_inode() may allocate a new inode from the reserved
inode area where it should not be allocated.
Previous fix commit d325dc6eb763 ("nilfs2: fix use-after-free bug of
struct nilfs_root"), fixed the problem that reserved inodes with inode
numbers less than NILFS_USER_INO (=11) were incorrectly reallocated due to
bitmap corruption, but since the start number of non-reserved inodes is
read from the super block and may change, in which case inode allocation
may occur from the extended reserved inode area.
If that happens, access to that inode will cause an IO error, causing the
file system to degrade to an error state.
Fix this potential issue by adding a wraparound option to the common
metadata object allocation routine and by modifying
nilfs_ifile_create_inode() to disable the option so that it only allocates
inodes with inode numbers greater than or equal to the inode number read
in "nilfs->ns_first_ino", regardless of the bitmap status of reserved
inodes.

Syzbot reported that mounting and unmounting a specific pattern of
corrupted nilfs2 filesystem images causes a use-after-free of metadata
file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file
gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(),
tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers
of these metadata files that should not be visible in the namespace are
read without checking.
Fix this issue by treating the inode numbers of these internal files as
errors in the sanity check helper when reading directory folios/pages.
Also thanks to Hillf Danton and Matthew Wilcox for their initial mm-layer
analysis.

Patch series "nilfs2: fix potential issues related to reserved inodes".
This series fixes one use-after-free issue reported by syzbot, caused by
nilfs2's internal inode being exposed in the namespace on a corrupted
filesystem, and a couple of flaws that cause problems if the starting
number of non-reserved inodes written in the on-disk super block is
intentionally (or corruptly) changed from its default value.
This patch (of 3):
In the current implementation of nilfs2, "nilfs->ns_first_ino", which
gives the first non-reserved inode number, is read from the superblock,
but its lower limit is not checked.
As a result, if a number that overlaps with the inode number range of
reserved inodes such as the root directory or metadata files is set in the
super block parameter, the inode number test macros (NILFS_MDT_INODE and
NILFS_VALID_INODE) will not function properly.
In addition, these test macros use left bit-shift calculations using with
the inode number as the shift count via the BIT macro, but the result of a
shift calculation that exceeds the bit width of an integer is undefined in
the C specification, so if "ns_first_ino" is set to a large value other
than the default value NILFS_USER_INO (=11), the macros may potentially
malfunction depending on the environment.
Fix these issues by checking the lower bound of "nilfs->ns_first_ino" and
by preventing bit shifts equal to or greater than the NILFS_USER_INO
constant in the inode number test macros.
Also, change the type of "ns_first_ino" from signed integer to unsigned
integer to avoid the need for type casting in comparisons such as the
lower bound check introduced this time.

The dirty throttling logic is interspersed with assumptions that dirty
limits in PAGE_SIZE units fit into 32-bit (so that various multiplications
fit into 64-bits). If limits end up being larger, we will hit overflows,
possible divisions by 0 etc. Fix these problems by never allowing so
large dirty limits as they have dubious practical value anyway. For
dirty_bytes / dirty_background_bytes interfaces we can just refuse to set
so large limits. For dirty_ratio / dirty_background_ratio it isn't so
simple as the dirty limit is computed from the amount of available memory
which can change due to memory hotplug etc. So when converting dirty
limits from ratios to numbers of pages, we just don't allow the result to
exceed UINT_MAX.
This is root-only triggerable problem which occurs when the operator
sets dirty limits to >16 TB.

Patch series "mm: Avoid possible overflows in dirty throttling".
Dirty throttling logic assumes dirty limits in page units fit into
32-bits. This patch series makes sure this is true (see patch 2/2 for
more details).
This patch (of 2):
This reverts commit 9319b647902cbd5cc884ac08a8a6d54ce111fc78.
The commit is broken in several ways. Firstly, the removed (u64) cast
from the multiplication will introduce a multiplication overflow on 32-bit
archs if wb_thresh * bg_thresh >= 1<<32 (which is actually common - the
default settings with 4GB of RAM will trigger this). Secondly, the
div64_u64() is unnecessarily expensive on 32-bit archs. We have
div64_ul() in case we want to be safe & cheap. Thirdly, if dirty
thresholds are larger than 1<<32 pages, then dirty balancing is going to
blow up in many other spectacular ways anyway so trying to fix one
possible overflow is just moot.

When mm_update_owner_next() is racing with swapoff (try_to_unuse()) or

If the above race condition is combined with the stress-ng-zombie and

write_lock_irq() for tasklist_lock.

The kernel test robot reported that clang no longer compiles the 32-bit
x86 kernel in some configurations due to commit 95ece48165c1
("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}()
functions").
The build fails with
arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available
and the reason seems to be that not only does the cmpxchg8b instruction
need four fixed registers (EDX:EAX and ECX:EBX), with the emulation
fallback the inline asm also wants a fifth fixed register for the
address (it uses %esi for that, but that's just a software convention
with cmpxchg8b_emu).
Avoiding using another pointer input to the asm (and just forcing it to
use the "0(%esi)" addressing that we end up requiring for the sw
fallback) seems to fix the issue.

The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.
Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.
And the code really does depend on stack layout that is only true in the
simplest of cases. We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:
Assume the lock function has either no stack frame or a copy
of eflags from PUSHF.
which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:
Eflags always has bits 22 and up cleared unlike kernel addresses
but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.
It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].
With no real practical reason for this any more, just remove the code.
Just for historical interest, here's some background commits relating to
this code from 2006:
0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
31679f38d886 ("Simplify profile_pc on x86-64")
and a code unification from 2009:
ef4512882dbe ("x86: time_32/64.c unify profile_pc")
but the basics of this thing actually goes back to before the git tree.

When clearing registers on new write requests was added, the protection
for currently running commands was missed leading to concurrent access
to the testunit registers. Check the flag beforehand.

STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.

Revert "nfsd: fix oops when reading pool_stats before server is started"

simple stuff:
- null ptr/err ptr deref fixes
- fix for getting wedged on shutdown after journal error
- fix missing recalc_capacity() call, capacity now changes correctly
after a device goes read only
however: our capacity calculation still doesn't take into account when
we have mixed ro/rw devices and the ro devices have data on them,
that's going to be a more involved fix to separate accounting for
"capacity used on ro devices" and "capacity used on rw devices"
- boring syzbot stuff
slightly more involved:
- discard, invalidate workers are now per device
this has the effect of simplifying how we take device refs in these
paths, and the device ref cleanup fixes a longstanding race between
the device removal path and the discard path
- fixes for how the debugfs code takes refs on btree_trans objects
we have debugfs code that prints in use btree_trans objects. It uses
closure_get() on trans->ref, which is mainly for the cycle detector,
but the debugfs code was using it on a closure that may have hit 0,
which is not allowed; for performance reasons we cannot avoid having
not-in-use transactions on the global list.
