git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic updates from Arnd Bergmann:
"There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good.
This was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly tricky
and error-prone code. There is a small merge conflict against a
parisc cleanup, the solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel.
The hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks"

Pull ARM updates from Russell King:
"Updates for IRQ stacks and virtually mapped stack support, and ftrace:
- Support for IRQ and vmap'ed stacks
This covers all the work related to implementing IRQ stacks and
vmap'ed stacks for all 32-bit ARM systems that are currently
supported by the Linux kernel, including RiscPC and Footbridge. It
has been submitted for review in four different waves:
- IRQ stacks support for v7 SMP systems [0]
- vmap'ed stacks support for v7 SMP systems[1]
- extending support for both IRQ stacks and vmap'ed stacks for all
remaining configurations, including v6/v7 SMP multiplatform
kernels and uniprocessor configurations including v7-M [2]
- fixes and updates in [3]
- ftrace fixes and cleanups
Make all flavors of ftrace available on all builds, regardless of
ISA choice, unwinder choice or compiler [4]:
- use ADD not POP where possible
- fix a couple of Thumb2 related issues
- enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness
- enable the graph tracer with the EABI unwinder
- avoid clobbering frame pointer registers to make Clang happy
- Fixes for the above"

Pull filesystem folio updates from Matthew Wilcox:
"Primarily this series converts some of the address_space operations to
take a folio instead of a page.
Notably:
- a_ops->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.
- a_ops->invalidatepage() becomes ->invalidate_folio() and has a
similar type change.
- a_ops->launder_page() becomes ->launder_folio()
- a_ops->set_page_dirty() becomes ->dirty_folio() and adds the
address_space as an argument.

Let's make it clearer at which places we actually add and remove memory
blocks -- streamlining the terminology -- and highlight which memory block
start out online and which start out as offline.
* rename add_memory_block -> add_boot_memory_block
* rename init_memory_block -> add_memory_block
* rename unregister_memory -> remove_memory_block
* rename register_memory -> __add_memory_block
* add add_hotplug_memory_block
* mark add_boot_memory_block with __init (suggested by Oscar)
__add_memory_block() is a pure helper for add_memory_block(), remove
the somewhat obvious comment.

test_pages_in_a_zone() is just another nasty PFN walker that can easily
stumble over ZONE_DEVICE memory ranges falling into the same memory block
as ordinary system RAM: the memmap of parts of these ranges might possibly
be uninitialized. In fact, we observed (on an older kernel) with UBSAN:
UBSAN: Undefined behaviour in ./include/linux/mm.h:1133:50
index 7 is out of range for type 'zone [5]'

RIP: 0033:0x7f01f4439b52
We seem to stumble over a memmap that contains a garbage zone id. While
we could try inserting pfn_to_online_page() calls, it will just make
memory offlining slower, because we use test_pages_in_a_zone() to make
sure we're offlining pages that all belong to the same zone.
Let's just get rid of this PFN walker and determine the single zone of a
memory block -- if any -- for early memory blocks during boot. For memory
onlining, we know the single zone already. Let's avoid any additional
memmap scanning and just rely on the zone information available during
boot.
For memory hot(un)plug, we only really care about memory blocks that:
* span a single zone (and, thereby, a single node)
* are completely System RAM (IOW, no holes, no ZONE_DEVICE)
If one of these conditions is not met, we reject memory offlining.
Hotplugged memory blocks (starting out offline), always meet both
conditions.
There are three scenarios to handle:
(1) Memory hot(un)plug
A memory block with zone == NULL cannot be offlined, corresponding to
our previous test_pages_in_a_zone() check.
After successful memory onlining/offlining, we simply set the zone
accordingly.
* Memory onlining: set the zone we just used for onlining
* Memory offlining: set zone = NULL
So a hotplugged memory block starts with zone = NULL. Once memory
onlining is done, we set the proper zone.
(2) Boot memory with !CONFIG_NUMA
We know that there is just a single pgdat, so we simply scan all zones
of that pgdat for an intersection with our memory block PFN range when
adding the memory block. If more than one zone intersects (e.g., DMA and
DMA32 on x86 for the first memory block) we set zone = NULL and
consequently mimic what test_pages_in_a_zone() used to do.
(3) Boot memory with CONFIG_NUMA
At the point in time we create the memory block devices during boot, we
don't know yet which nodes *actually* span a memory block. While we could
scan all zones of all nodes for intersections, overlapping nodes complicate
the situation and scanning all nodes is possibly expensive. But that
problem has already been solved by the code that sets the node of a memory
block and creates the link in the sysfs --
do_register_memory_block_under_node().
So, we hook into the code that sets the node id for a memory block. If
we already have a different node id set for the memory block, we know
that multiple nodes *actually* have PFNs falling into our memory block:
we set zone = NULL and consequently mimic what test_pages_in_a_zone() used
to do. If there is no node id set, we do the same as (2) for the given
node.
Note that the call order in driver_init() is:
-> memory_dev_init(): create memory block devices
-> node_dev_init(): link memory block devices to the node and set the
node id
So in summary, we detect if there is a single zone responsible for this
memory block and we consequently store the zone in that case in the
memory block, updating it during memory onlining/offlining.

register_memory_block_under_node()
Patch series "drivers/base/memory: determine and store zone for single-zone memory blocks", v2.
I remember talking to Michal in the past about removing
test_pages_in_a_zone(), which we use for:
* verifying that a memory block we intend to offline is really only managed
by a single zone. We don't support offlining of memory blocks that are
managed by multiple zones (e.g., multiple nodes, DMA and DMA32)
* exposing that zone to user space via
/sys/devices/system/memory/memory*/valid_zones
Now that I identified some more cases where test_pages_in_a_zone() might
go wrong, and we received an UBSAN report (see patch #3), let's get rid of
this PFN walker.
So instead of detecting the zone at runtime with test_pages_in_a_zone() by
scanning the memmap, let's determine and remember for each memory block if
it's managed by a single zone. The stored zone can then be used for the
above two cases, avoiding a manual lookup using test_pages_in_a_zone().
This avoids eventually stumbling over uninitialized memmaps in corner
cases, especially when ZONE_DEVICE ranges partly fall into memory block
(that are responsible for managing System RAM).
Handling memory onlining is easy, because we online to exactly one zone.
Handling boot memory is more tricky, because we want to avoid scanning all
zones of all nodes to detect possible zones that overlap with the physical
memory region of interest. Fortunately, we already have code that
determines the applicable nodes for a memory block, to create sysfs links
-- we'll hook into that.
Patch #1 is a simple cleanup I had laying around for a longer time.
Patch #2 contains the main logic to remove test_pages_in_a_zone() and
further details.

unregister_memory_block_under_nodes() and
do_register_memory_block_under_node(). We're dealing with memory block

node_dev_init()
... and call node_dev_init() after memory_dev_init() from driver_init(),
so before any of the existing arch/subsys calls. All online nodes should
be known at that point: early during boot, arch code determines node and
zone ranges and sets the relevant nodes online; usually this happens in
setup_arch().
This is in line with memory_dev_init(), which initializes the memory
device subsystem and creates all memory block devices.
Similar to memory_dev_init(), panic() if anything goes wrong, we don't
want to continue with such basic initialization errors.
The important part is that node_dev_init() gets called after
memory_dev_init() and after cpu_dev_init(), but before any of the relevant
archs call register_cpu() to register the new cpu device under the node
device. The latter should be the case for the current users of
topology_init().

succeeded
If register_memory() fails, we freed the memory block but already added
the memory block to the group list, not good. Let's defer adding the
block to the memory group to after registering the memory block device.
We do handle it properly during unregister_memory(), but that's not
called when the registration fails.

When the hwpoison page meets the filter conditions, it should not be
regarded as successful memory_failure() processing for mce handler, but
should return a distinct value, otherwise mce handler regards the error
page has been identified and isolated, which may lead to calling
set_mce_nospec() to change page attribute, etc.
Here memory_failure() return -EOPNOTSUPP to indicate that the error
event is filtered, mce handler should not take any action for this
situation and hwpoison injector should treat as correct.

Some places in the kernel don't really expect pageblock_order >=
MAX_ORDER, and it looks like this is only possible in corner cases:
1) CONFIG_DEFERRED_STRUCT_PAGE_INIT we'll end up freeing pageblock_order
pages via __free_pages_core(), which cannot possibly work.
2) find_zone_movable_pfns_for_nodes() will roundup the ZONE_MOVABLE
start PFN to MAX_ORDER_NR_PAGES. Consequently with a bigger
pageblock_order, we could have a single pageblock partially managed by
two zones.
3) compaction code runs into __fragmentation_index() with order
>= MAX_ORDER, when checking WARN_ON_ONCE(order >= MAX_ORDER). [1]
4) mm/page_reporting.c won't be reporting any pages with default
page_reporting_order == pageblock_order, as we'll be skipping the
reporting loop inside page_reporting_process_zone().
5) __rmqueue_fallback() will never be able to steal with
ALLOC_NOFRAGMENT.
pageblock_order >= MAX_ORDER is weird either way: it's a pure
optimization for making alloc_contig_range(), as used for allcoation of
gigantic pages, a little more reliable to succeed. However, if there is
demand for somewhat reliable allocation of gigantic pages, affected
setups should be using CMA or boottime allocations instead.
So let's make sure that pageblock_order < MAX_ORDER and simplify.

Patch series "mm: enforce pageblock_order < MAX_ORDER".
Having pageblock_order >= MAX_ORDER seems to be able to happen in corner
cases and some parts of the kernel are not prepared for it.
For example, Aneesh has shown [1] that such kernels can be compiled on
ppc64 with 64k base pages by setting FORCE_MAX_ZONEORDER=8, which will
run into a WARN_ON_ONCE(order >= MAX_ORDER) in comapction code right
during boot.
We can get pageblock_order >= MAX_ORDER when the default hugetlb size is
bigger than the maximum allocation granularity of the buddy, in which
case we are no longer talking about huge pages but instead gigantic
pages.
Having pageblock_order >= MAX_ORDER can only make alloc_contig_range()
of such gigantic pages more likely to succeed.
Reliable use of gigantic pages either requires boot time allcoation or
CMA, no need to overcomplicate some places in the kernel to optimize for
corner cases that are broken in other areas of the kernel.
This patch (of 2):
Let's enforce pageblock_order < MAX_ORDER and simplify.
Especially patch #1 can be regarded a cleanup before:
[PATCH v5 0/6] Use pageblock_order for cma and alloc_contig_range

At each login the user forces the kernel to create a new terminal and
allocate up to ~1Kb memory for the tty-related structures.
By default it's allowed to create up to 4096 ptys with 1024 reserve for
initial mount namespace only and the settings are controlled by host
admin.
Though this default is not enough for hosters with thousands of
containers per node. Host admin can be forced to increase it up to
NR_UNIX98_PTY_MAX = 1<<20.
By default container is restricted by pty mount_opt.max = 1024, but
admin inside container can change it via remount. As a result, one
container can consume almost all allowed ptys and allocate up to 1Gb of
unaccounted memory.
It is not enough per-se to trigger OOM on host, however anyway, it
allows to significantly exceed the assigned memcg limit and leads to
troubles on the over-committed node.
It makes sense to account for them to restrict the host's memory
consumption from inside the memcg-limited container.

These functions are no longer useful as no BDIs report congestions any
more.
Removing the test on bdi_write_contested() in current_may_throttle()
could cause a small change in behaviour, but only when PF_LOCAL_THROTTLE
is set.
So replace the calls by 'false' and simplify the code - and remove the
functions.

This reverts commit 6f98a4bfee72c22f50aedb39fb761567969865fe.
It turns out we still can't do this. Way too many platforms that don't
have any real source of randomness at boot and no jitter entropy because
they don't even have a cycle counter.
As reported by Guenter Roeck:
"This causes a large number of qemu boot test failures for various
architectures (arm, m68k, microblaze, sparc32, xtensa are the ones I
observed).
Common denominator is that boot hangs at 'Saving random seed:'"
This isn't hugely unexpected - we tried it, it failed, so now we'll
revert it.

new SPI drivers this cycle, I'm not expecting any build issues
resulting from the change.
Otherwise it's been a relatively quiet release with some new device

conversion of the subsystem to use GPIO descriptors rather than
numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO

Pull random number generator updates from Jason Donenfeld:
"There have been a few important changes to the RNG's crypto, but the
intent for 5.18 has been to shore up the existing design as much as
possible with modern cryptographic functions and proven constructions,
rather than actually changing up anything fundamental to the RNG's
design.
So it's still the same old RNG at its core as before: it still counts
entropy bits, and collects from the various sources with the same
heuristics as before, and so forth. However, the cryptographic
algorithms that transform that entropic data into safe random numbers
have been modernized.
Just as important, if not more, is that the code has been cleaned up
and re-documented. As one of the first drivers in Linux, going back to
1.3.30, its general style and organization was showing its age and
becoming both a maintenance burden and an auditability impediment.
Hopefully this provides a more solid foundation to build on for the
future. I encourage you to open up the file in full, and maybe you'll
remark, "oh, that's what it's doing," and enjoy reading it. That, at
least, is the eventual goal, which this pull begins working toward.
Here's a summary of the various patches in this pull:
- /dev/urandom and /dev/random now do the same thing, per the patch
we discussed on the list. I think this is worth trying out. If it
does appear problematic, I've made sure to keep it standalone and
revertible without any conflicts.
- Fixes and cleanups for numerous integer type problems, locking
issues, and general code quality concerns.
- The input pool's LFSR has been replaced with a cryptographically
secure hash function, which has security and performance benefits
alike, and consequently allows us to count entropy bits linearly.
- The pre-init injection now uses a real hash function too, instead
of an LFSR or vanilla xor.
- The interrupt handler's fast_mix() function now uses one round of
SipHash, rather than the fake crypto that was there before.
- All additions of RDRAND and RDSEED now go through the input pool's
hash function, in part to mitigate ridiculous hypothetical CPU
backdoors, but more so to have a consistent interface for ingesting
entropy that's easy to analyze, making everything happen one way,
instead of a potpourri of different ways.
- The crng now works on per-cpu data, while also being in accordance
with the actual "fast key erasure RNG" design. This allows us to
fix several boot-time race complications associated with the prior
dynamically allocated model, eliminates much locking, and makes our
backtrack protection more robust.
- Batched entropy now erases doled out values so that it's backtrack
resistant.
- Working closely with Sebastian, the interrupt handler no longer
needs to take any locks at all, as we punt the
synchronized/expensive operations to a workqueue. This is
especially nice for PREEMPT_RT, where taking spinlocks in irq
context is problematic. It also makes the handler faster for the
rest of us.
- Also working with Sebastian, we now do the right thing on CPU
hotplug, so that we don't use stale entropy or fail to accumulate
new entropy when CPUs come back online.
- We handle virtual machines that fork / clone / snapshot, using the
"vmgenid" ACPI specification for retrieving a unique new RNG seed,
which we can use to also make WireGuard (and in the future, other
things) safe across VM forks.
- Around boot time, we now try to reseed more often if enough entropy
is available, before settling on the usual 5 minute schedule.
- Last, but certainly not least, the documentation in the file has
been updated considerably"

platform-level _OSC handling change to make it actually take the
platform firmware response into account, some code and documentation
cleanups, and a notable update of the ACPI device enumeration
documentation.

academic concern.

Pull tpm updates from Jarkko Sakkinen:
"In order to split the work a bit we've aligned with David Howells more
or less that I take more hardware/firmware aligned keyring patches,
and he takes care more of the framework aligned patches.
For TPM the patches worth of highlighting are the fixes for
refcounting provided by Lino Sanfilippo and James Bottomley.
Eric B. has done a bunch obvious (but important) fixes but there's one
a bit controversial: removal of asym_tpm. It was added in 2018 when
TPM1 was already declared as insecure and world had moved on to TPM2.
I don't know how this has passed all the filters but I did not have a
chance to see the patches when they were out. I simply cannot commit
to maintaining this because it was from all angles just wrong to take
it in the first place to the mainline kernel. Nobody should use this
module really for anything.
Finally, there is a new keyring '.machine' to hold MOK keys ('Machine
Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be
set, from which kernel knows that MOK keys are kernel trusted keys and
they are populated to the machine keyring. This keyring linked to the
secondary trusted keyring, which means that can be used like any
kernel trusted keys. This keyring of course can be used to hold other
MOK'ish keys in other platforms in future"
