Documentation/mm: rrefer kmap_local_page() and avoid kmap()
The reasoning for converting kmap() to kmap_local_page() was questioned recently.[1] There are two main problems with kmap(): (1) It comes with an overhead as mapping space is restricted and protected by a global lock for synchronization and (2) kmap() also requires global TLB invalidation when its pool wraps and it might block when the mapping space is fully utilized until a slot becomes available. Warn users to avoid the use of kmap() and instead use kmap_local_page(), by designing their code to map pages in the same context the mapping will be used.

Documentation/mm: avoid invalid use of addresses from kmap_local_page()
Users of kmap_local_page() must be absolutely sure to not hand kernel virtual address obtained calling kmap_local_page() on highmem pages to other contexts because those pointers are thread local, therefore, they are no longer valid across different contexts. Extend the documentation of kmap_local_page() to warn users about the above-mentioned potential invalid use of pointers returned by kmap_local_page().

Documentation/mm: don't kmap*() pages which can't come from HIGHMEM
There is no need to kmap*() pages which are guaranteed to come from
ZONE_NORMAL (or lower). Linux has currently several call sites of
kmap{,_atomic,_local_page}() on pages which are clearly known which can't
come from ZONE_HIGHMEM.
Therefore, add a paragraph to highmem.rst, to explain better that a plain
page_address() may be used for getting the address of pages which cannot
come from ZONE_HIGHMEM, although it is always safe to use
kmap_local_page() / kunmap_local() also on those pages.

highmem: specify that kmap_local_page() is callable from interrupts
In a recent thread about converting kmap() to kmap_local_page(), the safety of calling kmap_local_page() was questioned.[1] "any context" should probably be enough detail for users who want to know whether or not kmap_local_page() can be called from interrupts. However, Linux still has kmap_atomic() which might make users think they must use the latter in interrupts. Add "including interrupts" for better clarity.

highmem: remove unneeded spaces in kmap_local_page() kdocs
Patch series "highmem: Extend kmap_local_page() documentation", v2. The Highmem interface is evolving and the current documentation does not reflect the intended uses of each of the calls. Furthermore, after a recent series of reworks, the differences of the calls can still be confusing and may lead to the expanded use of calls which are deprecated. This series is the second round of changes towards an enhanced documentation of the Highmem's interface; at this stage the patches are only focused to kmap_local_page(). In addition it also contains some minor clean ups. This patch (of 7): In the kdocs of kmap_local_page(), the description of @page starts after several unnecessary spaces. Therefore, remove those spaces.

mm, hwpoison: skip raw hwpoison page in freeing 1GB hugepage
Currently if memory_failure() (modified to remove blocking code with
subsequent patch) is called on a page in some 1GB hugepage, memory error
handling fails and the raw error page gets into leaked state. The impact
is small in production systems (just leaked single 4kB page), but this
limits the testability because unpoison doesn't work for it. We can no
longer create 1GB hugepage on the 1GB physical address range with such
leaked pages, that's not useful when testing on small systems.
When a hwpoison page in a 1GB hugepage is handled, it's caught by the
PageHWPoison check in free_pages_prepare() because the 1GB hugepage is
broken down into raw error pages before coming to this point:
if (unlikely(PageHWPoison(page)) && !order) {
...
return false;
}
Then, the page is not sent to buddy and the page refcount is left 0.
Originally this check is supposed to work when the error page is freed
from page_handle_poison() (that is called from soft-offline), but now we
are opening another path to call it, so the callers of
__page_handle_poison() need to handle the case by considering the return
value 0 as success. Then page refcount for hwpoison is properly
incremented so unpoison works.

mm, hwpoison: set PG_hwpoison for busy hugetlb pages
If memory_failure() fails to grab page refcount on a hugetlb page because
it's busy, it returns without setting PG_hwpoison on it. This not only
loses a chance of error containment, but breaks the rule that
action_result() should be called only when memory_failure() do any of
handling work (even if that's just setting PG_hwpoison). This
inconsistency could harm code maintainability.
So set PG_hwpoison and call hugetlb_set_page_hwpoison() for such a case.

mm, hwpoison, hugetlb: support saving mechanism of raw error pages
When handling memory error on a hugetlb page, the error handler tries to dissolve and turn it into 4kB pages. If it's successfully dissolved, PageHWPoison flag is moved to the raw error page, so that's all right. However, dissolve sometimes fails, then the error page is left as hwpoisoned hugepage. It's useful if we can retry to dissolve it to save healthy pages, but that's not possible now because the information about where the raw error pages is lost. Use the private field of a few tail pages to keep that information. The code path of shrinking hugepage pool uses this info to try delayed dissolve. In order to remember multiple errors in a hugepage, a singly-linked list originated from SUBPAGE_INDEX_HWPOISON-th tail page is constructed. Only simple operations (adding an entry or clearing all) are required and the list is assumed not to be very long, so this simple data structure should be enough. If we failed to save raw error info, the hwpoison hugepage has errors on unknown subpage, then this new saving mechanism does not work any more, so disable saving new raw error info and freeing hwpoison hugepages.

mm/hugetlb: make pud_huge() and follow_huge_pud() aware of non-present pud entry
follow_pud_mask() does not support non-present pud entry now. As long as I tested on x86_64 server, follow_pud_mask() still simply returns no_page_table() for non-present_pud_entry() due to pud_bad(), so no severe user-visible effect should happen. But generally we should call follow_huge_pud() for non-present pud entry for 1GB hugetlb page. Update pud_huge() and follow_huge_pud() to handle non-present pud entries. The changes are similar to previous works for pud entries commit |

mm/hugetlb: check gigantic_page_runtime_supported() in return_unused_surplus_pages()
Patch series "mm, hwpoison: enable 1GB hugepage support", v7.
This patch (of 8):
I found a weird state of 1GB hugepage pool, caused by the following
procedure:
- run a process reserving all free 1GB hugepages,
- shrink free 1GB hugepage pool to zero (i.e. writing 0 to
/sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages), then
- kill the reserving process.
, then all the hugepages are free *and* surplus at the same time.
$ cat /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages
3
$ cat /sys/kernel/mm/hugepages/hugepages-1048576kB/free_hugepages
3
$ cat /sys/kernel/mm/hugepages/hugepages-1048576kB/resv_hugepages
0
$ cat /sys/kernel/mm/hugepages/hugepages-1048576kB/surplus_hugepages
3
This state is resolved by reserving and allocating the pages then freeing
them again, so this seems not to result in serious problem. But it's a
little surprising (shrinking pool suddenly fails).
This behavior is caused by hstate_is_gigantic() check in
return_unused_surplus_pages(). This was introduced so long ago in 2008 by
commit

mm: hugetlb_vmemmap: improve hugetlb_vmemmap code readability
There is a discussion about the name of hugetlb_vmemmap_alloc/free in
thread [1]. The suggestion suggested by David is rename "alloc/free" to
"optimize/restore" to make functionalities clearer to users, "optimize"
means the function will optimize vmemmap pages, while "restore" means
restoring its vmemmap pages discared before. This commit does this.
Another discussion is the confusion RESERVE_VMEMMAP_NR isn't used
explicitly for vmemmap_addr but implicitly for vmemmap_end in
hugetlb_vmemmap_alloc/free. David suggested we can compute what
hugetlb_vmemmap_init() does now at runtime. We do not need to worry for
the overhead of computing at runtime since the calculation is simple
enough and those functions are not in a hot path. This commit has the
following improvements:
1) The function suffixed name ("optimize/restore") is more expressive.
2) The logic becomes less weird in hugetlb_vmemmap_optimize/restore().
3) The hugetlb_vmemmap_init() does not need to be exported anymore.
4) A ->optimize_vmemmap_pages field in struct hstate is killed.
5) There is only one place where checks is_power_of_2(sizeof(struct
page)) instead of two places.
6) Add more comments for hugetlb_vmemmap_optimize/restore().
7) For external users, hugetlb_optimize_vmemmap_pages() is used for
detecting if the HugeTLB's vmemmap pages is optimizable originally.
In this commit, it is killed and we introduce a new helper
hugetlb_vmemmap_optimizable() to replace it. The name is more
expressive.

mm: hugetlb_vmemmap: optimize vmemmap_optimize_mode handling
We hold an another reference to hugetlb_optimize_vmemmap_key when making vmemmap_optimize_mode on, because we use static_key to tell memory_hotplug that memory_hotplug.memmap_on_memory should be overridden. However, this rule has gone when we have introduced PageVmemmapSelfHosted. Therefore, we could simplify vmemmap_optimize_mode handling by not holding an another reference to hugetlb_optimize_vmemmap_key. This also means that we not incur the extra page_fixed_fake_head checks if there are no vmemmap optinmized hugetlb pages after this change.

mm: hugetlb_vmemmap: delete hugetlb_optimize_vmemmap_enabled()
Patch series "Simplify hugetlb vmemmap and improve its readability", v2.
This series aims to simplify hugetlb vmemmap and improve its readability.
This patch (of 8):
The name hugetlb_optimize_vmemmap_enabled() a bit confusing as it tests
two conditions (enabled and pages in use). Instead of coming up to an
appropriate name, we could just delete it. There is already a discussion
about deleting it in thread [1].
There is only one user of hugetlb_optimize_vmemmap_enabled() outside of
hugetlb_vmemmap, that is flush_dcache_page() in arch/arm64/mm/flush.c.
However, it does not need to call hugetlb_optimize_vmemmap_enabled() in
flush_dcache_page() since HugeTLB pages are always fully mapped and only
head page will be set PG_dcache_clean meaning only head page's flag may
need to be cleared (see commit

TTY / Serial driver changes for 6.0-rc1
Here is the big set of tty and serial driver changes for 6.0-rc1. It was delayed from last week as I wanted to make sure the last commit here got some good testing in linux-next and elsewhere as it seemed to show up only late in testing for some reason. Nothing major here, just lots of cleanups from Jiri and Ilpo to make the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo). Also included in here is the obligatory n_gsm updates from Daniel Starke and lots of tiny driver updates and minor fixes and tweaks for other smaller serial drivers. Full details are in the shortlog. All of these have been in linux-next for a while with no reported problems.

f2fs-for-6.0
In this cycle, we mainly fixed some corner cases that manipulate a per-file
compression flag inappropriately. And, we found f2fs counted valid blocks in a
section incorrectly when zone capacity is set, and thus, fixed it with
additional sysfs entry to check it easily. Lastly, this series includes
several patches with respect to the new atomic write support such as a
couple of bug fixes and re-adding atomic_write_abort support that we removed
by mistake in the previous release.
Enhancement:
- add sysfs entries to understand atomic write operations and zone
capacity
- introduce memory mode to get a hint for low-memory devices
- adjust the waiting time of foreground GC
- decompress clusters under softirq to avoid non-deterministic latency
- do not skip updating inode when retrying to flush node page
- enforce single zone capacity
Bug fix:
- set the compression/no-compression flags correctly
- revive F2FS_IOC_ABORT_VOLATILE_WRITE
- check inline_data during compressed inode conversion
- understand zone capacity when calculating valid block count
As usual, the series includes several minor clean-ups and sanity checks.

vfs: Check the truncate maximum size in inode_newsize_ok()
If something manages to set the maximum file size to MAX_OFFSET+1, this
can cause the xfs and ext4 filesystems at least to become corrupt.
Ordinarily, the kernel protects against userspace trying this by
checking the value early in the truncate() and ftruncate() system calls
calls - but there are at least two places that this check is bypassed:
(1) Cachefiles will round up the EOF of the backing file to DIO block
size so as to allow DIO on the final block - but this might push
the offset negative. It then calls notify_change(), but this
inadvertently bypasses the checking. This can be triggered if
someone puts an 8EiB-1 file on a server for someone else to try and
access by, say, nfs.
(2) ksmbd doesn't check the value it is given in set_end_of_file_info()
and then calls vfs_truncate() directly - which also bypasses the
check.
In both cases, it is potentially possible for a network filesystem to
cause a disk filesystem to be corrupted: cachefiles in the client's
cache filesystem; ksmbd in the server's filesystem.
nfsd is okay as it checks the value, but we can then remove this check
too.
Fix this by adding a check to inode_newsize_ok(), as called from
setattr_prepare(), thereby catching the issue as filesystems set up to
perform the truncate with minimal opportunity for bypassing the new
check.

* Update the semantic patches in the kernel that contain a URL for
Coccinelle with a URL that is currently valid (from myself).
* Add a semantic patch checking for unnecessary NULL tests on dev_{put,
hold} functions (from Ziyang Xuan, followed bt a modification from
myself).
* Drop a semantic patch that replaces 0/1 by booleans, as this change was
considered to be not worthwhile by some maintainers (from Steve Rostedt).
* Extend an existing semantic patch with more checks for useless tests on
variables addresses (from Jérémy Lefaure).

The zgetdump tool from s390-tools package will decrypt the CPU state using a Customer Communication Key and overwrite respective notes to make the data accessible for crash and other debugging tools. - Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto test. - Fix incorrect recovery of kretprobe modified return address in stacktrace. - Switch the NMI handler to use generic irqentry_nmi_enter() and irqentry_nmi_exit() helper functions. - Rework the cryptographic Adjunct Processors (AP) pass-through design to support dynamic changes to the AP matrix of a running guest as well as to implement more of the AP architecture. - Minor boot code cleanups. - Grammar and typo fixes to hmcdrv and tape drivers. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCYu4dRBccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8DnlAP45Sk4cE35T+Z0vdHE2f0uMXE/p uHNjS3fDZOQVFJ2jZwEA99xPF5qPCttbR/b1VHsMSb30684IT1A4PC7y05kgfAw= =jCc3 -----END PGP SIGNATURE----- Merge tag 's390-5.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Rework copy_oldmem_page() callback to take an iov_iter.

- Add flags argument to dm_bufio_client_create and introduce
DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather than mutex for its locking. - Add optional "try_verify_in_tasklet" feature to DM verity target. This feature gives users the option to improve IO latency by using a tasklet to verify, using hashes in bufio's cache, rather than wait to schedule a work item via workqueue. But if there is a bufio cache miss, or an error, then the tasklet will fallback to using workqueue. - Incremental changes to both dm-bufio and the DM verity target to use jump_label to minimize cost of branching associated with the niche "try_verify_in_tasklet" feature. DM-bufio in particular is used by quite a few other DM targets so it doesn't make sense to incur additional bufio cost in those targets purely for the benefit of this niche verity feature if the feature isn't ever used. - Optimize verity_verify_io, which is used by both workqueue and tasklet based verification, if FEC is not configured or tasklet based verification isn't used. - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if "try_verify_in_tasklet" is specified. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmLtYU0ACgkQxSPxCi2d A1pIDwgAjQi7jSxN7n+Fb4sJLL5x3WvuVGcockIkucj+Pvr3nvijwkf27+kbCWhn d4bDhA60gCebd87lf2PZTf8LL2+h9SLzFDTrgBVg5eC4O8aoQNrgwMMKVvYn+MmK OShurwHXS/7iqCETFaUA7hVtH/NwSWzP7WL5+QIDVOWVGaTLnqdvA4TYSZnljEg2 c02bL2KK+ndsYYshDq7HnVuqr4hIBWKF6y0lApU42mfTCnghX8ZnUMG9pO9K+20X qVfQH58CjOTP0MaHsddyR1sTKKZ1qY1HdoDhnlMVfZD5XqnCMhzefKoMxbxJKmJ3 7hS5w2tNxSx4yYWGj3dXHKhEZi0buA== =ZBi4 -----END PGP SIGNATURE----- Merge tag 'for-6.0/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull more device mapper updates from Mike Snitzer: - Add flags argument to dm_bufio_client_create and introduce DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather than mutex for its locking. - Add optional "try_verify_in_tasklet" feature to DM verity target.
