khugepaged: fix null-pointer dereference due to race
khugepaged has to drop mmap lock several times while collapsing a page.
The situation can change while the lock is dropped and we need to
re-validate that the VMA is still in place and the PMD is still subject
for collapse.
But we miss one corner case: while collapsing an anonymous pages the VMA
could be replaced with file VMA. If the file VMA doesn't have any
private pages we get NULL pointer dereference:
general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN

The fix is to make sure that the VMA is anonymous in
hugepage_vma_revalidate(). The helper is only used for collapsing
anonymous pages.

mm/hugetlb: avoid hardcoding while checking if cma is enabled
hugetlb_cma[0] can be NULL due to various reasons, for example, node0
has no memory. so NULL hugetlb_cma[0] doesn't necessarily mean cma is
not enabled. gigantic pages might have been reserved on other nodes.
This patch fixes possible double reservation and CMA leak.

mm: memcg/slab: fix memory leak at non-root kmem_cache destroy
If the kmem_cache refcount is greater than one, we should not mark the
root kmem_cache as dying. If we mark the root kmem_cache dying
incorrectly, the non-root kmem_cache can never be destroyed. It
resulted in memory leak when memcg was destroyed. We can use the
following steps to reproduce.
1) Use kmem_cache_create() to create a new kmem_cache named A.
2) Coincidentally, the kmem_cache A is an alias for kmem_cache B,
so the refcount of B is just increased.
3) Use kmem_cache_destroy() to destroy the kmem_cache A, just
decrease the B's refcount but mark the B as dying.
4) Create a new memory cgroup and alloc memory from the kmem_cache
B. It leads to create a non-root kmem_cache for allocating memory.
5) When destroy the memory cgroup created in the step 4), the
non-root kmem_cache can never be destroyed.
If we repeat steps 4) and 5), this will cause a lot of memory leak. So
only when refcount reach zero, we mark the root kmem_cache as dying.

mm/memcg: fix refcount error while moving and swapping
It was hard to keep a test running, moving tasks between memcgs with
move_charge_at_immigrate, while swapping: mem_cgroup_id_get_many()'s
refcount is discovered to be 0 (supposedly impossible), so it is then
forced to REFCOUNT_SATURATED, and after thousands of warnings in quick
succession, the test is at last put out of misery by being OOM killed.
This is because of the way moved_swap accounting was saved up until the
task move gets completed in __mem_cgroup_clear_mc(), deferred from when
mem_cgroup_move_swap_account() actually exchanged old and new ids.
Concurrent activity can free up swap quicker than the task is scanned,
bringing id refcount down 0 (which should only be possible when
offlining).
Just skip that optimization: do that part of the accounting immediately.

mm/memcontrol: fix OOPS inside mem_cgroup_get_nr_swap_pages()
Prabhakar reported an OOPS inside mem_cgroup_get_nr_swap_pages()
function in a corner case seen on some arm64 boards when kdump kernel
runs with "cgroup_disable=memory" passed to the kdump kernel via
bootargs.
The root-cause behind the same is that currently mem_cgroup_swap_init()
function is implemented as a subsys_initcall() call instead of a
core_initcall(), this means 'cgroup_memory_noswap' still remains set to
the default value (false) even when memcg is disabled via
"cgroup_disable=memory" boot parameter.
This may result in premature OOPS inside mem_cgroup_get_nr_swap_pages()
function in corner cases:

mm/mmap.c: close race between munmap() and expand_upwards()/downwards()
VMA with VM_GROWSDOWN or VM_GROWSUP flag set can change their size under
mmap_read_lock(). It can lead to race with __do_munmap():
Thread A Thread B
__do_munmap()
detach_vmas_to_be_unmapped()
mmap_write_downgrade()
expand_downwards()
vma->vm_start = address;
// The VMA now overlaps with
// VMAs detached by the Thread A
// page fault populates expanded part
// of the VMA
unmap_region()
// Zaps pagetables partly
// populated by Thread B
Similar race exists for expand_upwards().
The fix is to avoid downgrading mmap_lock in __do_munmap() if detached
VMAs are next to VM_GROWSDOWN or VM_GROWSUP VMA.

gdb.base/corefile.exp test in GDB's test suite.
In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel XSAVES area. Thus the
correct mask corresponding to XCR0 was not present in the core file for
GDB to interrogate, resulting in the following behavior:
[kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core
Reading symbols from testsuite/outputs/gdb.base/corefile/corefile...
[New LWP 232880]
warning: Unexpected size of section `.reg-xstate/232880' in core file.
With the typo fixed, the test works again as expected.

Third batch of perf tooling fixes for 5.8:
- Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI.
- Set opt->set in libsubcmd's OPT_CALLBACK_SET(). Fixes
'perf record --switch-output-event event-name' usage.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

A pile of fixes for x86:
- Fix the I/O bitmap invalidation on XEN PV, which was overlooked in the
recent ioperm/iopl rework. This caused the TSS and XEN's I/O bitmap to
get out of sync.
- Use the proper vectors for HYPERV.
- Make disabling of stack protector for the entry code work with GCC
builds which enable stack protector by default. Removing the option is
not sufficient, it needs an explicit -fno-stack-protector to shut it
off.
- Mark check_user_regs() noinstr as it is called from noinstr code. The
missing annotation causes it to be placed in the text section which
makes it instrumentable.
- Add the missing interrupt disable in exc_alignment_check()
- Fixup a XEN_PV build dependency in the 32bit entry code
- A few fixes to make the Clang integrated assembler happy
- Move EFI stub build to the right place for out of tree builds
- Make prepare_exit_to_usermode() static. It's not longer called from ASM
code.

Two fixes for the timer wheel:
- A timer which is already expired at enqueue time can set the
base->next_expiry value backwards. As a consequence base->clk can be set
back as well. This can lead to timers expiring early. Add a sanity check
to prevent this.
- When a timer is queued with an expiry time beyond the wheel capacity
then it should be queued in the bucket of the last wheel level which is
expiring last. The code adjusts expiry time to the maximum wheel
capacity, which is only correct when the wheel clock is 0. Aside of that
the check whether the delta is larger than wheel capacity does not check
the delta, it checks the expiry value itself. As a result timers can
expire at random.
Fix this by checking the right variable and adjust expiry time so it
becomes base->clock plus capacity which places it into the outmost
bucket in the last wheel level.

Pull timer fixes from Thomas Gleixner:
"Two fixes for the timer wheel:
- A timer which is already expired at enqueue time can set the
base->next_expiry value backwards. As a consequence base->clk can
be set back as well. This can lead to timers expiring early. Add a
sanity check to prevent this.
- When a timer is queued with an expiry time beyond the wheel
capacity then it should be queued in the bucket of the last wheel
level which is expiring last.
The code adjusted the expiry time to the maximum wheel capacity,
which is only correct when the wheel clock is 0. Aside of that the
check whether the delta is larger than wheel capacity does not
check the delta, it checks the expiry value itself. As a result
timers can expire at random.
Fix this by checking the right variable and adjust expiry time so
it becomes base->clock plus capacity which places it into the
outmost bucket in the last wheel level"

A set of scheduler fixes:
- Plug a load average accounting race which was introduced with a recent
optimization casing load average to show bogus numbers.
- Fix the rseq CPU id initialization for new tasks. sched_fork() does not
update the rseq CPU id so the id is the stale id of the parent task,
which can cause user space data corruption.
- Handle a 0 return value of task_h_load() correctly in the load balancer,
which does not decrease imbalance and therefore pulls until the maximum
number of loops is reached, which might be all tasks just created by a
fork bomb.

Two fixes for the interrupt subsystem:
- Make the handling of the firmware node consistent and do not free the
node after the domain has been created successfully. The core code
stores a pointer to it which can lead to a use after free or double
free.
This used to "work" because the pointer was not stored when the initial
code was written, but at some point later it was required to store
it. Of course nobody noticed that the existing users break that way.
- Handle affinity setting on inactive interrupts correctly when
hierarchical irq domains are enabled. When interrupts are inactive with
the modern hierarchical irqdomain design, the interrupt chips are not
necessarily in a state where affinity changes can be handled. The legacy
irq chip design allowed this because interrupts are immediately fully
initialized at allocation time. X86 has a hacky workaround for this, but
other implementations do not. This cased malfunction on GIC-V3. Instead
of playing whack a mole to find all affected drivers, change the core
code to store the requested affinity setting and then establish it when
the interrupt is allocated, which makes the X86 hack go away.

changeset d0213061a501 ("media: atomisp: fix mask and shift operation on ISPSSPM0")
solved the existing issue with the IUNIT power on code.
So, the driver can now use the right code again.

media: atomisp: fix mask and shift operation on ISPSSPM0
Currently the check on bits 25:24 on ISPSSPM0 is always 0 because
the mask and shift operations are incorrect. Fix this by shifting
by MRFLD_ISPSSPM0_ISPSSS_OFFSET (24 bits right) and then masking
with RFLD_ISPSSPM0_ISPSSC_MASK (0x03) to get the appropriate 2 bits
to check.

x86/boot: Don't add the EFI stub to targets
vmlinux-objs-y is added to targets, which currently means that the EFI
stub gets added to the targets as well. It shouldn't be added since it
is built elsewhere.
This confuses Makefile.build which interprets the EFI stub as a target
$(obj)/$(objtree)/drivers/firmware/efi/libstub/lib.a
and will create drivers/firmware/efi/libstub/ underneath
arch/x86/boot/compressed, to hold this supposed target, if building
out-of-tree. [0]
Fix this by pulling the stub out of vmlinux-objs-y into efi-obj-y.
[0] See scripts/Makefile.build near the end:

x86/entry: Actually disable stack protector
Some builds of GCC enable stack protector by default. Simply removing
the arguments is not sufficient to disable stack protector, as the stack
protector for those GCC builds must be explicitly disabled. Remove the
argument removals and add -fno-stack-protector. Additionally include
missed x32 argument updates, and adjust whitespace for readability.

media: atomisp: get rid of version-specific system_local.h

media: atomisp: move global stuff into a common header
Right now, there are two versions of system_global.h headers. Both share a lot of common code. There are some ISP2401 specific types on one of the headers, but it doesn't conflict with the ISP2400 ones. Also, the common code is identical. So, remove code duplication by moving such code into a common header. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

media: atomisp: remove non-used 32-bits consts at system_local
There is an abstraction at the code in order to support 32 or 64 bits address/data length. However, for all Atom chipsets supported by this version, the size is fixed. So, cleanup the mess, removing the uused code and placing the data sizes on a single place. The end goal is to completely remove those local/global headers, replacing them by some ISP-version dependent struct, in order for the driver to decide what version it would need in runtime.

RISC-V Fixes for 5.8-rc6
I have two fixes:
* 16KiB kernel stacks on rv64, which fixes a lot of crashes.
* Rolling an mmiowb() into the scheduled, which when combined with Will's fix
to the mmiowb()-on-spinlock should fix the PREEMPT issues we've been seeing.

Pull RISC-V fixes from Palmer Dabbelt:
"Two fixes:
- 16KiB kernel stacks on rv64, which fixes a lot of crashes.
- Rolling an mmiowb() into the scheduler, which when combined with
Will's fix to the mmiowb()-on-spinlock should fix the PREEMPT
issues we've been seeing"

powerpc fixes for 5.8 #7
A fix to the VAS code we merged this cycle, to report the proper error code to
userspace for address translation failures. And a selftest update to match.
Another fix for our pkey handling of PROT_EXEC mappings.
A fix for a crash when booting a "secure VM" under an ultravisor with certain
numbers of CPUs.

hwmon: (drivetemp) Avoid SCT usage on Toshiba DT01ACA family drives
It has been observed that Toshiba DT01ACA family drives have
WRITE FPDMA QUEUED command timeouts and sometimes just freeze until
power-cycled under heavy write loads when their temperature is getting
polled in SCT mode. The SMART mode seems to be fine, though.
Let's make sure we don't use SCT mode for these drives then.
While only the 3 TB model was actually caught exhibiting the problem let's
play safe here to avoid data corruption and extend the ban to the whole
family.

x86/ioperm: Fix io bitmap invalidation on Xen PV
tss_invalidate_io_bitmap() wasn't wired up properly through the pvop
machinery, so the TSS and Xen's io bitmap would get out of sync
whenever disabling a valid io bitmap.
Add a new pvop for tss_invalidate_io_bitmap() to fix it.
This is XSA-329.
