dax/kmem: Pass valid argument to memory_group_register_static
[ Upstream commit 46e66dab8565f742374e9cc4ff7d35f344d774e2 ]
memory_group_register_static takes maximum number of pages as the argument
while dev_dax_kmem_probe passes total_len (in bytes) as the argument.
IIUC, I don't see any crash/panic impact as such. As,
memory_group_register_static just set the max_pages limit which is used in
auto_movable_zone_for_pfn to determine the zone.
which might cause these condition to behave differently,
This will be true always so jump will happen to kernel_zone
...
if (!auto_movable_can_online_movable(NUMA_NO_NODE, group, nr_pages))
goto kernel_zone;
...
kernel_zone:
return default_kernel_zone_for_pfn(nid, pfn, nr_pages);
Here, In below, zone_intersects compare range will be larger as nr_pages
will be higher (derived from total_len passed in dev_dax_kmem_probe).
...
static struct zone *default_kernel_zone_for_pfn(int nid, unsigned long start_pfn,
unsigned long nr_pages)
{
struct pglist_data *pgdat = NODE_DATA(nid);
int zid;
for (zid = 0; zid < ZONE_NORMAL; zid++) {
struct zone *zone = &pgdat->node_zones[zid];
if (zone_intersects(zone, start_pfn, nr_pages))
return zone;
}
return &pgdat->node_zones[ZONE_NORMAL];
}
Incorrect zone will be returned here, which in later time might cause bigger
problem.

dax: Introduce alloc_dev_dax_id()
[ Upstream commit 70aab281e18c68a1284bc387de127c2fc0bed3f8 ]
The reference counting of dax_region objects is needlessly complicated,
has lead to confusion [1], and has hidden a bug [2]. Towards cleaning up
that mess introduce alloc_dev_dax_id() to minimize the holding of a
dax_region reference to only what dev_dax_release() needs, the
dax_region->ida.
Part of the reason for the mess was the design to dereference a
dax_region in all cases in free_dev_dax_id() even if the id was
statically assigned by the upper level dax_region driver. Remove the
need to call "is_static(dax_region)" by tracking whether the id is
dynamic directly in the dev_dax instance itself.
With that flag the dax_region pinning and release per dev_dax instance
can move to alloc_dev_dax_id() and free_dev_dax_id() respectively.
A follow-on cleanup address the unnecessary references in the dax_region
setup and drivers.

Due to attempting ida_free() on an ida object that has already been

registered. If a child needs a parent object to complete its release it
needs to hold a reference that it drops from its release callback.
Arrange for a dax_mapping to pin its parent dev_dax instance until
dax_mapping_release().

dax/kmem: Fix leak of memory-hotplug resources
commit e686c32590f40bffc45f105c04c836ffad3e531a upstream.
While experimenting with CXL region removal the following corruption of
/proc/iomem appeared.
Before:
f010000000-f04fffffff : CXL Window 0
f010000000-f02fffffff : region4
f010000000-f02fffffff : dax4.0
f010000000-f02fffffff : System RAM (kmem)
After (modprobe -r cxl_test):
f010000000-f02fffffff : **redacted binary garbage**
f010000000-f02fffffff : System RAM (kmem)
...and testing further the same is visible with persistent memory
assigned to kmem:
Before:
480000000-243fffffff : Persistent Memory
480000000-57e1fffff : namespace3.0
580000000-243fffffff : dax3.0
580000000-243fffffff : System RAM (kmem)
After (ndctl disable-region all):
480000000-243fffffff : Persistent Memory
580000000-243fffffff : ***redacted binary garbage***
580000000-243fffffff : System RAM (kmem)
The corrupted data is from a use-after-free of the "dax4.0" and "dax3.0"
resources, and it also shows that the "System RAM (kmem)" resource is
not being removed. The bug does not appear after "modprobe -r kmem", it
requires the parent of "dax4.0" and "dax3.0" to be removed which
re-parents the leaked "System RAM (kmem)" instances. Those in turn
reference the freed resource as a parent.
First up for the fix is release_mem_region_adjustable() needs to
reliably delete the resource inserted by add_memory_driver_managed().
That is thwarted by a check for IORESOURCE_SYSRAM that predates the
dax/kmem driver, from commit:

device-dax: Fix duplicate 'hmem' device registration
So called "soft-reserved" memory is an EFI conventional memory range with the EFI_MEMORY_SP attribute set. That attribute indicates that the memory is not part of the platform general purpose memory pool and may want some consideration from the system administrator about whether to keep that memory set aside for dedicated access through device-dax (map a device file), or assigned to the page allocator as another general purpose memory node target. Absent an ACPI HMAT table the default device-dax registration creates coarse grained devices that are delineated by EFI Memory Map entries. With the HMAT the devices are delineated by the finer grained ranges associated with the proximity domain of the memory target. I.e. the HMAT describes the properties of performance differentiated memory and each unique performance description results in a unique target proximity domain where each memory proximity domain has an associated SRAT entry that delineates the address range. The intent was that SRAT-defined device-dax instances are registered first. Then any left-over address range with the EFI_MEMORY_SP attribute, but not covered by the SRAT, would have a coarse grained device-dax instance established. However, the scheme to detect what ranges are left to be assigned to a device was buggy and resulted in multiple overlapping device-dax instances. Fix this by using explicit tracking for which ranges have been handled. Now, this new approach may leave memory stranded in the presence of broken platform firmware that fails to fully describe all EFI_MEMORY_SP ranges in the HMAT. That requires a deeper fix if it becomes a problem in practice.

- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees.

devdax: Fix soft-reservation memory description
The "hmem" platform-devices that are created to represent the
platform-advertised "Soft Reserved" memory ranges end up inserting a
resource that causes the iomem_resource tree to look like this:
340000000-43fffffff : hmem.0
340000000-43fffffff : Soft Reserved
340000000-43fffffff : dax0.0
This is because insert_resource() reparents ranges when they completely
intersect an existing range.
This matters because code that uses region_intersects() to scan for a
given IORES_DESC will only check that top-level 'hmem.0' resource and
not the 'Soft Reserved' descendant.
So, to support EINJ (via einj_error_inject()) to inject errors into
memory hosted by a dax-device, be sure to describe the memory as
IORES_DESC_SOFT_RESERVED. This is a follow-on to:

dax: introduce holder for dax_device
Patch series "v14 fsdax-rmap + v11 fsdax-reflink", v2. The patchset fsdax-rmap is aimed to support shared pages tracking for fsdax. It moves owner tracking from dax_assocaite_entry() to pmem device driver, by introducing an interface ->memory_failure() for struct pagemap. This interface is called by memory_failure() in mm, and implemented by pmem device. Then call holder operations to find the filesystem which the corrupted data located in, and call filesystem handler to track files or metadata associated with this page. Finally we are able to try to fix the corrupted data in filesystem and do other necessary processing, such as killing processes who are using the files affected. The call trace is like this: memory_failure() |* fsdax case |------------ |pgmap->ops->memory_failure() => pmem_pgmap_memory_failure() | dax_holder_notify_failure() => | dax_device->holder_ops->notify_failure() => | - xfs_dax_notify_failure() | |* xfs_dax_notify_failure() | |-------------------------- | | xfs_rmap_query_range() | | xfs_dax_failure_fn() | | * corrupted on metadata | | try to recover data, call xfs_force_shutdown() | | * corrupted on file data | | try to recover data, call mf_dax_kill_procs() |* normal case |------------- |mf_generic_kill_procs() The patchset fsdax-reflink attempts to add CoW support for fsdax, and takes XFS, which has both reflink and fsdax features, as an example. One of the key mechanisms needed to be implemented in fsdax is CoW. Copy the data from srcmap before we actually write data to the destination iomap. And we just copy range in which data won't be changed. Another mechanism is range comparison. In page cache case, readpage() is used to load data on disk to page cache in order to be able to compare data. In fsdax case, readpage() does not work. So, we need another compare data with direct access support. With the two mechanisms implemented in fsdax, we are able to make reflink and fsdax work together in XFS. This patch (of 14): To easily track filesystem from a pmem device, we introduce a holder for dax_device structure, and also its operation. This holder is used to remember who is using this dax_device: - When it is the backend of a filesystem, the holder will be the instance of this filesystem. - When this pmem device is one of the targets in a mapped device, the holder will be this mapped device. In this case, the mapped device has its own dax_device and it will follow the first rule. So that we can finally track to the filesystem we needed. The holder and holder_ops will be set when filesystem is being mounted, or an target device is being activated.

dax: add .recovery_write dax_operation
Introduce dax_recovery_write() operation. The function is used to recover a dax range that contains poison. Typical use case is when a user process receives a SIGBUS with si_code BUS_MCEERR_AR indicating poison(s) in a dax range, in response, the user process issues a pwrite() to the page-aligned dax range, thus clears the poison and puts valid data in the range.

dax: introduce DAX_RECOVERY_WRITE dax access mode
Up till now, dax_direct_access() is used implicitly for normal
access, but for the purpose of recovery write, dax range with
poison is requested. To make the interface clear, introduce
enum dax_access_mode {
DAX_ACCESS,
DAX_RECOVERY_WRITE,
}
where DAX_ACCESS is used for normal dax access, and
DAX_RECOVERY_WRITE is used for dax recovery write.

Filesystem folio changes for 5.18
Primarily this series converts some of the address_space operations
to take a folio instead of a page.
->is_partially_uptodate() takes a folio instead of a page and changes the
type of the 'from' and 'count' arguments to make it obvious they're bytes.
->invalidatepage() becomes ->invalidate_folio() and has a similar type change.
->launder_page() becomes ->launder_folio()
->set_page_dirty() becomes ->dirty_folio() and adds the address_space as
an argument.
There are a couple of other misc changes up front that weren't worth
separating into their own pull request.

Faults, consequently happen too at the specified @align specified at the creation, and those don't change throughout dax device lifetime. MCEs unmap a whole dax huge page, as well as splits occurring at the configured page size. Performance measured by gup_test improves considerably for unpin_user_pages() and altmap with NVDIMMs: $ gup_test -f /dev/dax1.0 -m 16384 -r 10 -S -a -n 512 -w (pin_user_pages_fast 2M pages) put:~71 ms -> put:~22 ms [altmap] (pin_user_pages_fast 2M pages) get:~524ms put:~525 ms -> get: ~127ms put:~71ms $ gup_test -f /dev/dax1.0 -m 129022 -r 10 -S -a -n 512 -w (pin_user_pages_fast 2M pages) put:~513 ms -> put:~188 ms [altmap with -m 127004] (pin_user_pages_fast 2M pages) get:~4.1 secs put:~4.12 secs -> get:~1sec put:~563ms .. as well as unpin_user_page_range_dirty_lock() being just as effective as THP/hugetlb[0] pages.

device-dax: set mapping prior to vmf_insert_pfn{,_pmd,pud}()
Normally, the @page mapping is set prior to inserting the page into a
page table entry. Make device-dax adhere to the same ordering, rather
than setting mapping after the PTE is inserted.
The address_space never changes and it is always associated with the
same inode and underlying pages. So, the page mapping is set once but
cleared when the struct pages are removed/freed (i.e. after
{devm_}memunmap_pages()).

device-dax: ensure dev_dax->pgmap is valid for dynamic devices
Right now, only static dax regions have a valid @pgmap pointer in its struct dev_dax. Dynamic dax case however, do not. In preparation for device-dax compound devmap support, make sure that dev_dax pgmap field is set after it has been allocated and initialized. dynamic dax device have the @pgmap is allocated at probe() and it's managed by devm (contrast to static dax region which a pgmap is provided and dax core kfrees it). So in addition to ensure a valid @pgmap, clear the pgmap when the dynamic dax device is released to avoid the same pgmap ranges to be re-requested across multiple region device reconfigs. Add a static_dev_dax() and use that helper in dev_dax_probe() to ensure the initialization differences between dynamic and static regions are more explicit. While at it, consolidate the ranges initialization when we allocate the @pgmap for the dynamic dax region case. Also take the opportunity to document the differences between static and dynamic da regions.

dax: Kill DEV_DAX_PMEM_COMPAT
The /sys/class/dax compatibility option has shipped in the kernel for 4 years now which should be sufficient time for tools to abandon the old ABI in favor of the /sys/bus/dax device-model. Delete it now and see if anyone screams. Since this compatibility option shipped there has been more reports of users being surprised by the compat ABI than surprised by the "new", so the compat infrastructure has outlived its usefulness. Recall that /sys/bus/dax device-model is required for the dax kmem driver which allows PMEM to be used as "System RAM". The following projects were known to have a dependency on /sys/class/dax and have dropped their dependency as of the listed version: - ndctl (including libndctl, daxctl, and libdaxctl): v64+ - fio: v3.13+ - pmdk: v1.5.2+ As further evidence this option is no longer needed some distributions have already stopped enabling CONFIG_DEV_DAX_PMEM_COMPAT.

dax/kmem: use a single static memory group for a single probed unit
Although dax/kmem users often disable auto-onlining and instead online memory manually (usually to ZONE_MOVABLE), there is still value in having auto-onlining be aware of the relationship of memory blocks.

We don't expect to remove multi-nid ranges; and if we'd ever do, we most probably don't care about removing multi-nid ranges that actually result in empty nodes. If ever required, we can detect the "multi-nid" scenario and simply try offlining all online nodes.

Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did the
following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
The latter one will cause a tiny merge issue with your tree, as there
was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,
please let me know.
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs
users at once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue.

dax: remove bdev_dax_supported
All callers already have a dax_device obtained from fs_dax_get_by_bdev at hand, so just pass that to dax_supported() insted of doing another lookup.
