lib/test_overflow.c: avoid tainting the kernel and fix wrap size
This adds __GFP_NOWARN to the kmalloc()-portions of the overflow test to
avoid tainting the kernel. Additionally fixes up the math on wrap size
to be architecture and page size agnostic.

lib/test_string.c: avoid masking memset16/32/64 failures
If a memsetXX implementation is completely broken and fails in the first
iteration, when i, j, and k are all zero, the failure is masked as zero
is returned. Failing in the first iteration is perhaps the most likely
failure, so this makes the tests pretty much useless. Avoid the
situation by always setting a random unused bit in the result on
failure.

lib/string.c: allow searching for NUL with strnchr
Patch series "lib/string: search for NUL with strchr/strnchr". I noticed an inconsistency where strchr and strnchr do not behave the same with respect to the trailing NUL. strchr is standardised and the kernel function conforms, and the kernel relies on the behavior. So, naturally strchr stays as-is and strnchr is what I change. While writing a few tests to verify that my new strnchr loop was sane, I noticed that the tests for memset16/32/64 had a problem. Since it's all about the lib/string.c file I made a short series of it all... This patch (of 3): strchr considers the terminating NUL to be part of the string, and NUL can thus be searched for with that function. For consistency, do the same with strnchr.

lib/list: tweak LIST_POISON2 for better code generation on x86_64
list_del() poisoning can generate 2 64-bit immediate loads but it also can generate one 64-bit immediate load and an addition: 48 b8 00 01 00 00 00 00 ad de movabs rax,0xdead000000000100 48 89 47 58 mov QWORD PTR [rdi+0x58],rax 48 05 00 01 00 00 <=====> add rax,0x100 48 89 47 60 mov QWORD PTR [rdi+0x60],rax However on x86_64 not all constants are equal: those within [-128, 127] range can be added with shorter "add r64, imm32" instruction: 48 b8 00 01 00 00 00 00 ad de movabs rax,0xdead000000000100 48 89 47 58 mov QWORD PTR [rdi+0x58],rax 48 83 c0 22 <======> add rax,0x22 48 89 47 60 mov QWORD PTR [rdi+0x60],rax Patch saves 2 bytes per some LIST_POISON2 usage.

get_maintainer: add ability to skip moderated mailing lists
Add a command line switch --no-moderated to skip L: mailing lists marked with 'moderated'. Some people prefer not emailing moderated mailing lists as the moderation time can be indeterminate and some emails can be intentionally dropped by a moderator. This can cause fragmentation of email threads when some are subscribed to a moderated list but others are not and emails are dropped.

linux/bits.h: make BIT(), GENMASK(), and friends available in assembly
BIT(), GENMASK(), etc. are useful to define register bits of hardware. However, low-level code is often written in assembly, where they are not available due to the hard-coded 1UL, 0UL. In fact, in-kernel headers such as arch/arm64/include/asm/sysreg.h use _BITUL() instead of BIT() so that the register bit macros are available in assembly. Using macros in include/uapi/linux/const.h have two reasons: [1] For use in uapi headers We should use underscore-prefixed variants for user-space. [2] For use in assembly code Since _BITUL() uses UL(1) instead of 1UL, it can be used as an alternative of BIT(). For [2], it is pretty easy to change BIT() etc. for use in assembly. This allows to replace _BUTUL() in kernel-space headers with BIT().

fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.
Normally, the inode's i_uid/i_gid are translated relative to s_user_ns, but this is not a correct behavior for proc. Since sysctl permission check in test_perm is done against GLOBAL_ROOT_[UG]ID, it makes more sense to use these values in u_[ug]id of proc inodes. In other words: although uid/gid in the inode is not read during test_perm, the inode logically belongs to the root of the namespace. I have confirmed this with Eric Biederman at LPC and in this thread: https://lore.kernel.org/lkml/87k1kzjdff.fsf@xmission.com Consequences ============ Since the i_[ug]id values of proc nodes are not used for permissions checks, this change usually makes no functional difference. However, it causes an issue in a setup where: * a namespace container is created without root user in container - hence the i_[ug]id of proc nodes are set to INVALID_[UG]ID * container creator tries to configure it by writing /proc/sys files, e.g. writing /proc/sys/kernel/shmmax to configure shared memory limit Kernel does not allow to open an inode for writing if its i_[ug]id are invalid, making it impossible to write shmmax and thus - configure the container. Using a container with no root mapping is apparently rare, but we do use this configuration at Google. Also, we use a generic tool to configure the container limits, and the inability to write any of them causes a failure. History ======= The invalid uids/gids in inodes first appeared due to |

mm: stub out all of swapops.h for !CONFIG_MMU
The whole header file deals with swap entries and PTEs, none of which can exist for nommu builds. The current nommu ports have lots of stubs to allow the inline functions in swapops.h to compile, but as none of this functionality is actually used there is no point in even providing it. This way we don't have to provide the stubs for the upcoming RISC-V nommu port, and can eventually remove it from the existing ports.

mm/cma.c: fail if fixed declaration can't be honored
The description of cma_declare_contiguous() indicates that if the
'fixed' argument is true the reserved contiguous area must be exactly at
the address of the 'base' argument.
However, the function currently allows the 'base', 'size', and 'limit'
arguments to be silently adjusted to meet alignment constraints. This
commit enforces the documented behavior through explicit checks that
return an error if the region does not fit within a specified region.

mm/z3fold.c: reinitialize zhdr structs after migration
z3fold_page_migration() calls memcpy(new_zhdr, zhdr, PAGE_SIZE).
However, zhdr contains fields that can't be directly coppied over (ex:
list_head, a circular linked list). We only need to initialize the
linked lists in new_zhdr, as z3fold_isolate_page() already ensures that
these lists are empty
Additionally it is possible that zhdr->work has been placed in a
workqueue. In this case we shouldn't migrate the page, as zhdr->work
references zhdr as opposed to new_zhdr.

mm/vmscan.c: calculate reclaimed slab caches in all reclaim paths
There are six different reclaim paths by now: - kswapd reclaim path - node reclaim path - hibernate preallocate memory reclaim path - direct reclaim path - memcg reclaim path - memcg softlimit reclaim path The slab caches reclaimed in these paths are only calculated in the above three paths. There're some drawbacks if we don't calculate the reclaimed slab caches. - The sc->nr_reclaimed isn't correct if there're some slab caches relcaimed in this path. - The slab caches may be reclaimed thoroughly if there're lots of reclaimable slab caches and few page caches. Let's take an easy example for this case. If one memcg is full of slab caches and the limit of it is 512M, in other words there're approximately 512M slab caches in this memcg. Then the limit of the memcg is reached and the memcg reclaim begins, and then in this memcg reclaim path it will continuesly reclaim the slab caches until the sc->priority drops to 0. After this reclaim stops, you will find there're few slab caches left, which is less than 20M in my test case. While after this patch applied the number is greater than 300M and the sc->priority only drops to 3.

mm/vmscan.c: add a new member reclaim_state in struct shrink_control
Patch series "mm/vmscan: calculate reclaimed slab in all reclaim paths". This patchset is to fix the issues in doing shrink slab. There're six different reclaim paths by now, - kswapd reclaim path - node reclaim path - hibernate preallocate memory reclaim path - direct reclaim path - memcg reclaim path - memcg softlimit reclaim path The slab caches reclaimed in these paths are only calculated in the above three paths. The issues are detailed explained in patch #2. We should calculate the reclaimed slab caches in every reclaim path. In order to do it, the struct reclaim_state is placed into the struct shrink_control. In node reclaim path, there'is another issue about shrinking slab, which is adressed in "mm/vmscan: shrink slab in node reclaim" (https://lore.kernel.org/linux-mm/1559874946-22960-1-git-send-email-laoar.shao@gmail.com/). This patch (of 2): The struct reclaim_state is used to record how many slab caches are reclaimed in one reclaim path. The struct shrink_control is used to control one reclaim path. So we'd better put reclaim_state into shrink_control.

lib/mpi/mpih-div.c:76:16: error: invalid use of a cast in a inline asm context requiring an l-value: remove the cast or build with -fheinous-gnu-extensions
udiv_qrnnd(qp[i], n1, n1, np[i], d);
~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
lib/mpi/longlong.h:423:20: note: expanded from macro 'udiv_qrnnd'
: "=a" ((USItype)(q)), \
~~~~~~~~~~^~
There is no point in doing a type cast for the output of an inline
assembler statement, so just remove the cast here, as we have done for
other architectures in the past.

mm/z3fold: don't try to use buddy slots after free
As reported by Henry Burns:
Running z3fold stress testing with address sanitization showed zhdr->slots
was being used after it was freed.
z3fold_free(z3fold_pool, handle)
free_handle(handle)
kmem_cache_free(pool->c_handle, zhdr->slots)
release_z3fold_page_locked_list(kref)
__release_z3fold_page(zhdr, true)
zhdr_to_pool(zhdr)
slots_to_pool(zhdr->slots) *BOOM*
To fix this, add pointer to the pool back to z3fold_header and modify
zhdr_to_pool to return zhdr->pool.

HMM patches for 5.3
Improvements and bug fixes for the hmm interface in the kernel:
- Improve clarity, locking and APIs related to the 'hmm mirror' feature
merged last cycle. In linux-next we now see AMDGPU and nouveau to be
using this API.
- Remove old or transitional hmm APIs. These are hold overs from the past
with no users, or APIs that existed only to manage cross tree conflicts.
There are still a few more of these cleanups that didn't make the merge
window cut off.
- Improve some core mm APIs:
* export alloc_pages_vma() for driver use
* refactor into devm_request_free_mem_region() to manage
DEVICE_PRIVATE resource reservations
* refactor duplicative driver code into the core dev_pagemap
struct
- Remove hmm wrappers of improved core mm APIs, instead have drivers use
the simplified API directly
- Remove DEVICE_PUBLIC
- Simplify the kconfig flow for the hmm users and core code

platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. From now on the Intel Speed Select Technology is supported thru a corresponding driver.
