KVM: Explicitly disallow activatating a gfn_to_pfn_cache with INVALID_GPA
Explicit disallow activating a gfn_to_pfn_cache with an error gpa, i.e. INVALID_GPA, to ensure that KVM doesn't mistake a GPA-based cache for an HVA-based cache (KVM uses INVALID_GPA as a magic value to differentiate between GPA-based and HVA-based caches). WARN if KVM attempts to activate a cache with INVALID_GPA, purely so that new caches need to at least consider what to do with a "bad" GPA, as all existing usage of kvm_gpc_activate() guarantees gpa != INVALID_GPA. I.e. removing the WARN in the future is completely reasonable if doing so would yield cleaner/better code overall.

KVM: Check validity of offset+length of gfn_to_pfn_cache prior to activation
When activating a gfn_to_pfn_cache, verify that the offset+length is sane
and usable before marking the cache active. Letting __kvm_gpc_refresh()
detect the problem results in a cache being marked active without setting
the GPA (or any other fields), which in turn results in KVM trying to
refresh a cache with INVALID_GPA.
Attempting to refresh a cache with INVALID_GPA isn't functionally
problematic, but it runs afoul of the sanity check that exactly one of
GPA or userspace HVA is valid, i.e. that a cache is either GPA-based or
HVA-based.

KVM: Add helpers to consolidate gfn_to_pfn_cache's page split check
Add a helper to check that the incoming length for a gfn_to_pfn_cache is valid with respect to the cache's GPA and/or HVA. To avoid activating a cache with a bogus GPA, a future fix will fork the page split check in the inner refresh path into activate() and the public rerfresh() APIs, at which point KVM will check the length in three separate places. Deliberately keep the "page offset" logic open coded, as the only other path that consumes the offset, __kvm_gpc_refresh(), already needs to differentiate between GPA-based and HVA-based caches, and it's not obvious that using a helper is a net positive in overall code readability. Note, for GPA-based caches, this has a subtle side effect of using the GPA instead of the resolved HVA in the check() path, but that should be a nop as the HVA offset is derived from the GPA, i.e. the two offsets are identical, barring a KVM bug.

firewire: ohci: mask bus reset interrupts between ISR and bottom half
In the FireWire OHCI interrupt handler, if a bus reset interrupt has occurred, mask bus reset interrupts until bus_reset_work has serviced and cleared the interrupt. Normally, we always leave bus reset interrupts masked. We infer the bus reset from the self-ID interrupt that happens shortly thereafter. A scenario where we unmask bus reset interrupts was introduced in 2008 in |

RISC-V Fixes for 6.9-rc3
* A fix for an __{get,put}_kernel_nofault to avoid an uninitialized
value causing spurious failures.
* compat_vdso.so.dbg is now installed to the standard install location.
* A fix to avoid initializing PERF_SAMPLE_BRANCH_*-related events, as
they aren't supported and will just later fail.
* A fix to make AT_VECTOR_SIZE_ARCH correct now that we're providing
AT_MINSIGSTKSZ.
* pgprot_nx() is now implemented, which fixes vmap W^X protection.
* A fix for the vector save/restore code, which at least manifests as
corrupted vector state when a signal is taken.
* A fix for a race condition in instruction patching.
* A fix to avoid leaking the kernel-mode GP to userspace, which is a
kernel pointer leak that can be used to defeat KASLR in various ways.
* A handful of smaller fixes to build warnings, an overzealous printk,
and some missing tracing annotations.

Thermal control fixes for 6.9-rc3
- Allow the power allocator thermal governor to bind to a thermal zone
without cooling devices and/or without trip points (Nikita Travkin).
- Make the ACPI thermal driver register a tripless thermal zone when

x86/mm/pat: fix VM_PAT handling in COW mappings
PAT handling won't do the right thing in COW mappings: the first PTE (or,
in fact, all PTEs) can be replaced during write faults to point at anon
folios. Reliably recovering the correct PFN and cachemode using
follow_phys() from PTEs will not work in COW mappings.
Using follow_phys(), we might just get the address+protection of the anon
folio (which is very wrong), or fail on swap/nonswap entries, failing
follow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() and
track_pfn_copy(), not properly calling free_pfn_range().
In free_pfn_range(), we either wouldn't call memtype_free() or would call
it with the wrong range, possibly leaking memory.
To fix that, let's update follow_phys() to refuse returning anon folios,
and fallback to using the stored PFN inside vma->vm_pgoff for COW mappings
if we run into that.
We will now properly handle untrack_pfn() with COW mappings, where we
don't need the cachemode. We'll have to fail fork()->track_pfn_copy() if
the first page was replaced by an anon folio, though: we'd have to store
the cachemode in the VMA to make this work, likely growing the VMA size.
For now, lets keep it simple and let track_pfn_copy() just fail in that
case: it would have failed in the past with swap/nonswap entries already,
and it would have done the wrong thing with anon folios.
Simple reproducer to trigger the WARN_ON_ONCE() in untrack_pfn():

mm: vmalloc: fix lockdep warning
A lockdep reports a possible deadlock in the find_vmap_area_exceed_addr_lock()
function:
============================================
WARNING: possible recursive locking detected
6.9.0-rc1-00060-ged3ccc57b108-dirty #6140 Not tainted
--------------------------------------------
drgn/455 is trying to acquire lock:
ffff0000c00131d0 (&vn->busy.lock/1){+.+.}-{2:2}, at: find_vmap_area_exceed_addr_lock+0x64/0x124
but task is already holding lock:

other info that might help us debug this:
Possible unsafe locking scenario:
CPU0
----
lock(&vn->busy.lock/1);
lock(&vn->busy.lock/1);
*** DEADLOCK ***
indeed it can happen if the find_vmap_area_exceed_addr_lock() gets called
concurrently because it tries to acquire two nodes locks. It was done to
prevent removing a lowest VA found on a previous step.
To address this a lowest VA is found first without holding a node lock
where it resides. As a last step we check if a VA still there because it
can go away, if removed, proceed with next lowest.

mm: vmalloc: bail out early in find_vmap_area() if vmap is not init
During the boot the s390 system triggers "spinlock bad magic" messages
if the spinlock debugging is enabled:

Some background. It worked before because the lock that is in question
was statically defined and initialized. As of now, the locks and data
structures are initialized in the vmalloc_init() function.
To address that issue add the check whether the "vmap_initialized"
variable is set, if not find_vmap_area() bails out on entry returning NULL.

init: open output files from cpio unpacking with O_LARGEFILE
If a member of a cpio archive for an initrd or initrams is larger than 2Gb, we'll eventually fail to write to that file when we get to that limit, unless O_LARGEFILE is set. The problem can be seen with this recipe, assuming that BLK_DEV_RAM is not configured: cd /tmp dd if=/dev/zero of=BIGFILE bs=1048576 count=2200 echo BIGFILE | cpio -o -H newc -R root:root > initrd.img kexec -l /boot/vmlinuz-$(uname -r) --initrd=initrd.img --reuse-cmdline kexec -e The console will show 'Initramfs unpacking failed: write error'. With the patch, the error is gone.

mm/secretmem: fix GUP-fast succeeding on secretmem folios
folio_is_secretmem() currently relies on secretmem folios being LRU
folios, to save some cycles.
However, folios might reside in a folio batch without the LRU flag set, or
temporarily have their LRU flag cleared. Consequently, the LRU flag is
unreliable for this purpose.
In particular, this is the case when secretmem_fault() allocates a fresh
page and calls filemap_add_folio()->folio_add_lru(). The folio might be
added to the per-cpu folio batch and won't get the LRU flag set until the
batch was drained using e.g., lru_add_drain().
Consequently, folio_is_secretmem() might not detect secretmem folios and
GUP-fast can succeed in grabbing a secretmem folio, crashing the kernel
when we would later try reading/writing to the folio, because the folio
has been unmapped from the directmap.
Fix it by removing that unreliable check.

nfsd: hold a lighter-weight client reference over CB_RECALL_ANY
Currently the CB_RECALL_ANY job takes a cl_rpc_users reference to the
client. While a callback job is technically an RPC that counter is
really more for client-driven RPCs, and this has the effect of
preventing the client from being unhashed until the callback completes.
If nfsd decides to send a CB_RECALL_ANY just as the client reboots, we
can end up in a situation where the callback can't complete on the (now
dead) callback channel, but the new client can't connect because the old
client can't be unhashed. This usually manifests as a NFS4ERR_DELAY
return on the CREATE_SESSION operation.
The job is only holding a reference to the client so it can clear a flag
after the RPC completes. Fix this by having CB_RECALL_ANY instead hold a
reference to the cl_nfsdfs.cl_ref. Typically we only take that sort of
reference when dealing with the nfsdfs info files, but it should work
appropriately here to ensure that the nfs4_client doesn't disappear.

Pull vfs fixes from Christian Brauner:
"This contains a few small fixes. This comes with some delay because I
wanted to wait on people running their reproducers and the Easter
Holidays meant that those replies came in a little later than usual:
- Fix handling of preventing writes to mounted block devices.
Since last kernel we allow to prevent writing to mounted block
devices provided CONFIG_BLK_DEV_WRITE_MOUNTED isn't set and the
block device is opened with restricted writes. When we switched to
opening block devices as files we altered the mechanism by which we
recognize when a block device has been opened with write
restrictions.
The detection logic assumed that only read-write mounted
filesystems would apply write restrictions to their block devices
from other openers. That of course is not true since it also makes
sense to apply write restrictions for filesystems that are
read-only.
Fix the detection logic using an FMODE_* bit. We still have a few
left since we freed up a couple a while ago. I also picked up a
patch to free up four additional FMODE_* bits scheduled for the
next merge window.
- Fix counting the number of writers to a block device. This just
changes the logic to be consistent.
- Fix a bug in aio causing a NULL pointer derefernce after we
implemented batched processing in aio.
- Finally, add the changes we discussed that allows to yield block
devices early even though file closing itself is deferred.
This also allows us to remove two holder operations to get and
release the holder to align lifetime of file and holder of the
block device"

aio: Fix null ptr deref in aio_complete() wakeup
list_del_init_careful() needs to be the last access to the wait queue
entry - it effectively unlocks access.
Previously, finish_wait() would see the empty list head and skip taking
the lock, and then we'd return - but the completion path would still
attempt to do the wakeup after the task_struct pointer had been
overwritten.

timers/migration: Fix ignored event due to missing CPU update
When a group event is updated with its expiry unchanged but a different
CPU, that target change may go unnoticed and the event may be propagated
up with a stale CPU value. The following depicts a scenario that has
been actually observed:
[GRP2:0]
migrator = GRP1:1
active = GRP1:1
nextevt = TGRP1:0 (T0)
/ \
[GRP1:0] [GRP1:1]
migrator = NONE [...]
active = NONE
nextevt = TGRP0:0 (T0)
/ \
[GRP0:0] [...]
migrator = NONE
active = NONE
nextevt = T0
/ \
0 (T0) 1 (T1)
idle idle
0) The hierarchy has 3 levels. The left part (GRP1:0) is all idle,
including CPU 0 and CPU 1 which have a timer each: T0 and T1. They have
the same expiry value.
[GRP2:0]
migrator = GRP1:1
active = GRP1:1
nextevt = KTIME_MAX
/ \
[GRP1:0] [GRP1:1]
migrator = NONE [...]
active = NONE
nextevt = TGRP0:0 (T0)
/ \
[GRP0:0] [...]
migrator = NONE
active = NONE
nextevt = T0
/ \
0 (T0) 1 (T1)
idle idle
1) The migrator in GRP1:1 handles remotely T0. The event is dequeued
from the top and T0 executed.
[GRP2:0]
migrator = GRP1:1
active = GRP1:1
nextevt = KTIME_MAX
/ \
[GRP1:0] [GRP1:1]
migrator = NONE [...]
active = NONE
nextevt = TGRP0:0 (T0)
/ \
[GRP0:0] [...]
migrator = NONE
active = NONE
nextevt = T1
/ \
0 1 (T1)
idle idle
2) The migrator in GRP1:1 fetches the next timer for CPU 0 and finds
none. But it updates the events from its groups, starting with GRP0:0
which now has T1 as its next event. So far so good.
[GRP2:0]
migrator = GRP1:1
active = GRP1:1
nextevt = KTIME_MAX
/ \
[GRP1:0] [GRP1:1]
migrator = NONE [...]
active = NONE
nextevt = TGRP0:0 (T0)
/ \
[GRP0:0] [...]
migrator = NONE
active = NONE
nextevt = T1
/ \
0 1 (T1)
idle idle
3) The migrator in GRP1:1 proceeds upward and updates the events in
GRP1:0. The child event TGRP0:0 is found queued with the same expiry
as before. And therefore it is left unchanged. However the target CPU
is not the same but that fact is ignored so TGRP0:0 still points to
CPU 0 when it should point to CPU 1.
[GRP2:0]
migrator = GRP1:1
active = GRP1:1
nextevt = TGRP1:0 (T0)
/ \
[GRP1:0] [GRP1:1]
migrator = NONE [...]
active = NONE
nextevt = TGRP0:0 (T0)
/ \
[GRP0:0] [...]
migrator = NONE
active = NONE
nextevt = T1
/ \
0 1 (T1)
idle idle
4) The propagation has reached the top level and TGRP1:0, having TGRP0:0
as its first event, also wrongly points to CPU 0. TGRP1:0 is added to
the top level group.
[GRP2:0]
migrator = GRP1:1
active = GRP1:1
nextevt = KTIME_MAX
/ \
[GRP1:0] [GRP1:1]
migrator = NONE [...]
active = NONE
nextevt = TGRP0:0 (T0)
/ \
[GRP0:0] [...]
migrator = NONE
active = NONE
nextevt = T1
/ \
0 1 (T1)
idle idle
5) The migrator in GRP1:1 dequeues the next event in top level pointing
to CPU 0. But since it actually doesn't see any real event in CPU 0, it
early returns.
6) T1 is left unhandled until either CPU 0 or CPU 1 wake up.
Some other bad scenario may involve trees with just two levels.
Fix this with unconditionally updating the CPU of the child event before
considering to early return while updating a queued event with an
unchanged expiry value.
