ucounts: Increase ucounts reference counter before the security hook
We need to increment the ucounts reference counter befor security_prepare_creds()
because this function may fail and abort_creds() will try to decrement
this reference.

After investigation the problem turned out to be that ucount_max for
the rlimits in init_user_ns was being set to the initial rlimit value.
The practical problem is that ucount_max provides a limit that
applications inside the user namespace can not exceed. Which means in
practice that rlimits that have been converted to use the ucount
infrastructure were not able to exceend their initial rlimits.
Solve this by setting the relevant values of ucount_max to
RLIM_INIFINITY. A limit in init_user_ns is pointless so the code
should allow the values to grow as large as possible without riscking
an underflow or an overflow.
As the ltp test case was a bit of a pain I have reproduced the rlimit failure
and tested the fix with the following little C program:
> #include <stdio.h>
> #include <fcntl.h>
> #include <sys/stat.h>
> #include <mqueue.h>
> #include <sys/time.h>

ucounts: Fix race condition between alloc_ucounts and put_ucounts
The race happens because put_ucounts() doesn't use spinlock and
get_ucounts is not under spinlock:

alloc_ucounts() put_ucounts()
spin_lock_irq(&ucounts_lock);

hlist_del_init(&ucounts->node);
spin_unlock_irqrestore(&ucounts_lock, flags);
kfree(ucounts);

==================================================================
- The race fix has two parts.
* Changing the code to guarantee that ucounts->count is only decremented
when ucounts_lock is held. This guarantees that find_ucounts
will never find a structure with a zero reference count.
* Changing alloc_ucounts to increment ucounts->count while
ucounts_lock is held. This guarantees the reference count on the
found data structure will not be decremented to zero (and the data
structure freed) before the reference count is incremented.

powerpc fixes for 5.14 #3
- Fix guest to host memory corruption in H_RTAS due to missing nargs check.
- Fix guest triggerable host crashes due to bad handling of nested guest TM state.
- Fix possible crashes due to incorrect reference counting in kvm_arch_vcpu_ioctl().
- Two commits fixing some regressions in KVM transactional memory handling introduced by
the recent rework of the KVM code.

riscv: __asm_copy_to-from_user: Fix: fail on RV32
Had a bug when converting bytes to bits when the cpu was rv32.
The a3 contains the number of bytes and multiple of 8
would be the bits. The LGREG is holding 2 for RV32 and 3 for
RV32, so to achieve multiple of 8 it must always be constant 3.
The 2 was mistakenly used for rv32.

riscv: __asm_copy_to-from_user: Fix: overrun copy
There were two causes for the overrun memory access.
The threshold size was too small.
The aligning dst require one SZREG and unrolling word copy requires
8*SZREG, total have to be at least 9*SZREG.
Inside the unrolling copy, the subtracting -(8*SZREG-1) would make
iteration happening one extra loop. Proper value is -(8*SZREG).

writeback, cgroup: do not reparent dax inodes
The inode switching code is not suited for dax inodes. An attempt to
switch a dax inode to a parent writeback structure (as a part of a
writeback cleanup procedure) results in a panic like this:

---[ end Kernel panic - not syncing: Fatal exception ]---
The crash happens on an attempt to iterate over attached pagecache pages
and check the dirty flag: a dax inode's xarray contains pfn's instead of
generic struct page pointers.
This happens for DAX and not for other kinds of non-page entries in the
inodes because it's a tagged iteration, and shadow/swap entries are
never tagged; only DAX entries get tagged.
Fix the problem by bailing out (with the false return value) of
inode_prepare_sbs_switch() if a dax inode is passed.

mm: call flush_dcache_page() in memcpy_to_page() and memzero_page()
memcpy_to_page and memzero_page can write to arbitrary pages, which could be in the page cache or in high memory, so call flush_kernel_dcache_pages to flush the dcache. This is a problem when using these helpers on dcache challeneged architectures. Right now there are just a few users, chances are no one used the PC floppy driver, the aha1542 driver for an ISA SCSI HBA, and a few advanced and optional btrfs and ext4 features on those platforms yet since the conversion.

kfence: skip all GFP_ZONEMASK allocations
Allocation requests outside ZONE_NORMAL (MOVABLE, HIGHMEM or DMA) cannot
be fulfilled by KFENCE, because KFENCE memory pool is located in a zone
different from the requested one.
Because callers of kmem_cache_alloc() may actually rely on the
allocation to reside in the requested zone (e.g. memory allocations
done with __GFP_DMA must be DMAable), skip all allocations done with
GFP_ZONEMASK and/or respective SLAB flags (SLAB_CACHE_DMA and
SLAB_CACHE_DMA32).

kfence: defer kfence_test_init to ensure that kunit debugfs is created
kfence_test_init and kunit_init both use the same level late_initcall, which means if kfence_test_init linked ahead of kunit_init, kfence_test_init will get a NULL debugfs_rootdir as parent dentry, then kfence_test_init and kfence_debugfs_init both create a debugfs node named "kfence" under debugfs_mount->mnt_root, and it will throw out "debugfs: Directory 'kfence' with parent '/' already present!" with EEXIST. So kfence_test_init should be deferred.

selftest: use mmap instead of posix_memalign to allocate memory
This test passes pointers obtained from anon_allocate_area to the
userfaultfd and mremap APIs. This causes a problem if the system
allocator returns tagged pointers because with the tagged address ABI
the kernel rejects tagged addresses passed to these APIs, which would
end up causing the test to fail. To make this test compatible with such
system allocators, stop using the system allocator to allocate memory in
anon_allocate_area, and instead just use mmap.

userfaultfd: do not untag user pointers
Patch series "userfaultfd: do not untag user pointers", v5. If a user program uses userfaultfd on ranges of heap memory, it may end up passing a tagged pointer to the kernel in the range.start field of the UFFDIO_REGISTER ioctl. This can happen when using an MTE-capable allocator, or on Android if using the Tagged Pointers feature for MTE readiness [1]. When a fault subsequently occurs, the tag is stripped from the fault address returned to the application in the fault.address field of struct uffd_msg. However, from the application's perspective, the tagged address *is* the memory address, so if the application is unaware of memory tags, it may get confused by receiving an address that is, from its point of view, outside of the bounds of the allocation. We observed this behavior in the kselftest for userfaultfd [2] but other applications could have the same problem. Address this by not untagging pointers passed to the userfaultfd ioctls. Instead, let the system call fail. Also change the kselftest to use mmap so that it doesn't encounter this problem. [1] https://source.android.com/devices/tech/debug/tagged-pointers [2] tools/testing/selftests/vm/userfaultfd.c This patch (of 2): Do not untag pointers passed to the userfaultfd ioctls. Instead, let the system call fail. This will provide an early indication of problems with tag-unaware userspace code instead of letting the code get confused later, and is consistent with how we decided to handle brk/mmap/mremap in commit |

io_uring: explicitly catch any illegal async queue attempt
Catch an illegal case to queue async from an unrelated task that got the ring fd passed to it. This should not be possible to hit, but better be proactive and catch it explicitly. io-wq is extended to check for early IO_WQ_WORK_CANCEL being set on a work item as well, so it can run the request through the normal cancelation path.

io_uring: never attempt iopoll reissue from release path
There are two reasons why this shouldn't be done: 1) Ring is exiting, and we're canceling requests anyway. Any request should be canceled anyway. In theory, this could iterate for a number of times if someone else is also driving the target block queue into request starvation, however the likelihood of this happening is miniscule. 2) If the original task decided to pass the ring to another task, then we don't want to be reissuing from this context as it may be an unrelated task or context. No assumptions should be made about the context in which ->release() is run. This can only happen for pure read/write, and we'll get -EFAULT on them anyway.
