TTY/Serial driver fixes for 6.12-rc4
Here are some small tty and serial driver fixes for 6.12-rc4. Included
in here are:
- qcom-geni serial driver fixes, wow what a mess of a UART chip that
thing is...
- vt infoleak fix for odd font sizes
- imx serial driver bugfix
- yet-another n_gsm ldisc bugfix, slowly chipping down the issues in
that piece of code.
All of these have been in linux-next for over a week with no reported
issues.

mm: huge_memory: add vma_thp_disabled() and thp_disabled_by_hw()
Patch series "mm: don't install PMD mappings when THPs are disabled by the
hw/process/vma".
During testing, it was found that we can get PMD mappings in processes
where THP (and more precisely, PMD mappings) are supposed to be disabled.
While it works as expected for anon+shmem, the pagecache is the
problematic bit.
For s390 KVM this currently means that a VM backed by a file located on
filesystem with large folio support can crash when KVM tries accessing the
problematic page, because the readahead logic might decide to use a
PMD-sized THP and faulting it into the page tables will install a PMD
mapping, something that s390 KVM cannot tolerate.
This might also be a problem with HW that does not support PMD mappings,
but I did not try reproducing it.
Fix it by respecting the ways to disable THPs when deciding whether we can
install a PMD mapping. khugepaged should already be taking care of not
collapsing if THPs are effectively disabled for the hw/process/vma.
This patch (of 2):
Add vma_thp_disabled() and thp_disabled_by_hw() helpers to be shared by
shmem_allowable_huge_orders() and __thp_vma_allowable_orders().
[david@redhat.com: rename to vma_thp_disabled(), split out thp_disabled_by_hw() ]

mm: percpu: increase PERCPU_DYNAMIC_SIZE_SHIFT on certain builds.
Arnd reported a build failure due to the BUILD_BUG_ON() statement in
alloc_kmem_cache_cpus(). The test
PERCPU_DYNAMIC_EARLY_SIZE < NR_KMALLOC_TYPES * KMALLOC_SHIFT_HIGH * sizeof(struct kmem_cache_cpu)
The factors that increase the right side of the equation:
- PAGE_SIZE > 4KiB increases KMALLOC_SHIFT_HIGH
- For the local_lock_t in kmem_cache_cpu:
- PREEMPT_RT adds an actual lock.
- LOCKDEP increases the size of the lock.
- LOCK_STAT adds additional bytes plus padding to the lockdep
structure.
The net difference with and without PREEMPT_RT is 88 bytes for the
lock_lock_t, 96 bytes for kmem_cache_cpu due to additional padding. This
is enough to exceed the 80KiB limit with 16KiB page size - the 8KiB page
size is fine.
Increase PERCPU_DYNAMIC_SIZE_SHIFT to 13 on configs with PAGE_SIZE larger
than 4KiB and LOCKDEP enabled.

iomap: remove iomap_file_buffered_write_punch_delalloc
Currently iomap_file_buffered_write_punch_delalloc can be called from XFS either with the invalidate lock held or not. To fix this while keeping the locking in the file system and not the iomap library code we'll need to life the locking up into the file system. To prepare for that, open code iomap_file_buffered_write_punch_delalloc in the only caller, and instead export iomap_write_delalloc_release.

sched/core: Disable page allocation in task_tick_mm_cid()
With KASAN and PREEMPT_RT enabled, calling task_work_add() in
task_tick_mm_cid() may cause the following splat.
[ 63.696416] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
[ 63.696416] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 610, name: modprobe
[ 63.696416] preempt_count: 10001, expected: 0
[ 63.696416] RCU nest depth: 1, expected: 1
This problem is caused by the following call trace.
sched_tick() [ acquire rq->__lock ]
-> task_tick_mm_cid()
-> task_work_add()
-> __kasan_record_aux_stack()
-> kasan_save_stack()
-> stack_depot_save_flags()

-> __alloc_pages_noprof()
-> get_page_from_freelist()
-> rmqueue()
-> rmqueue_pcplist()
-> __rmqueue_pcplist()
-> rmqueue_bulk()
-> rt_spin_lock()
The rq lock is a raw_spinlock_t. We can't sleep while holding
it. IOW, we can't call alloc_pages() in stack_depot_save_flags().
The task_tick_mm_cid() function with its task_work_add() call was

bcachefs: do not use PF_MEMALLOC_NORECLAIM
Patch series "remove PF_MEMALLOC_NORECLAIM" v3. This patch (of 2): bch2_new_inode relies on PF_MEMALLOC_NORECLAIM to try to allocate a new inode to achieve GFP_NOWAIT semantic while holding locks. If this allocation fails it will drop locks and use GFP_NOFS allocation context. We would like to drop PF_MEMALLOC_NORECLAIM because it is really dangerous to use if the caller doesn't control the full call chain with this flag set. E.g. if any of the function down the chain needed GFP_NOFAIL request the PF_MEMALLOC_NORECLAIM would override this and cause unexpected failure. While this is not the case in this particular case using the scoped gfp semantic is not really needed bacause we can easily pus the allocation context down the chain without too much clutter.

irqchip/gic-v4: Don't allow a VMOVP on a dying VPE
Kunkun Jiang reported that there is a small window of opportunity for
userspace to force a change of affinity for a VPE while the VPE has already
been unmapped, but the corresponding doorbell interrupt still visible in
/proc/irq/.
Plug the race by checking the value of vmapp_count, which tracks whether
the VPE is mapped ot not, and returning an error in this case.
This involves making vmapp_count common to both GICv4.1 and its v4.0
ancestor.

nfs_common: fix race in NFS calls to nfsd_file_put_local() and nfsd_serv_put()
Add nfs_to_nfsd_file_put_local() interface to fix race with nfsd module unload. Similarly, use RCU around nfs_open_local_fh()'s error path call to nfs_to->nfsd_serv_put(). Holding RCU ensures that NFS will safely _call and return_ from its nfs_to calls into the NFSD functions nfsd_file_put_local() and nfsd_serv_put(). Otherwise, if RCU isn't used then there is a narrow window when NFS's reference for the nfsd_file and nfsd_serv are dropped and the NFSD module could be unloaded, which could result in a crash from the return instruction for either nfs_to->nfsd_file_put_local() or nfs_to->nfsd_serv_put().

NFSv4: Prevent NULL-pointer dereference in nfs42_complete_copies()
On the node of an NFS client, some files saved in the mountpoint of the
NFS server were copied to another location of the same NFS server.
Accidentally, the nfs42_complete_copies() got a NULL-pointer dereference
crash with the following syslog:

Analysing the vmcore, we know that nfs4_copy_state listed by destination
nfs_server->ss_copies was added by the field copies in handle_async_copy(),
and we found a waiting copy process with the stack as:
PID: 3511963 TASK: ffff710028b47e00 CPU: 0 COMMAND: "cp"

#9 [ffff8001116efc50] __nfs4_copy_file_range.constprop.0 at ffff8000054ed694 [nfsv4]
The NULL-pointer dereference was due to nfs42_complete_copies() listed
the nfs_server->ss_copies by the field ss_copies of nfs4_copy_state.
So the nfs4_copy_state address ffff0100f98fa3f0 was offset by 0x10 and
the data accessed through this pointer was also incorrect. Generally,
the ordered list nfs4_state_owner->so_states indicate open(O_RDWR) or
open(O_WRITE) states are reclaimed firstly by nfs4_reclaim_open_state().
When destination state reclaim is failed with NFS_STATE_RECOVERY_FAILED
and copies are not deleted in nfs_server->ss_copies, the source state
may be passed to the nfs42_complete_copies() process earlier, resulting
in this crash scene finally. To solve this issue, we add a list_head
nfs_server->ss_src_copies for a server-to-server copy specially.

Merge tag 'vfs-6.12-rc2.fixes.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fixes from Christian Brauner:
"vfs:
- Ensure that iter_folioq_get_pages() advances to the next slot
otherwise it will end up using the same folio with an out-of-bound
offset.
iomap:
- Dont unshare delalloc extents which can't be reflinked, and thus
can't be shared.
- Constrain the file range passed to iomap_file_unshare() directly in
iomap instead of requiring the callers to do it.
netfs:
- Use folioq_count instead of folioq_nr_slot to prevent an
unitialized value warning in netfs_clear_buffer().
- Fix missing wakeup after issuing writes by scheduling the write
collector only if all the subrequest queues are empty and thus no
writes are pending.
- Fix two minor documentation bugs"

net: test for not too small csum_start in virtio_net_hdr_to_skb()
syzbot was able to trigger this warning [1], after injecting a
malicious packet through af_packet, setting skb->csum_start and thus
the transport header to an incorrect value.
We can at least make sure the transport header is after
the end of the network header (with a estimated minimal size).

This scenario shows that all notification groups are in principle prone to this kind of a deadlock (previously, we considered only fanotify and dnotify to be problematic for other reasons) so make sure all allocations under group->mark_mutex happen with GFP_NOFS.

cpufreq: Avoid a bad reference count on CPU node
In the parse_perf_domain function, if the call to of_parse_phandle_with_args returns an error, then the reference to the CPU device node that was acquired at the start of the function would not be properly decremented. Address this by declaring the variable with the __free(device_node) cleanup attribute.

net: Add netif_get_gro_max_size helper for GRO
Add a small netif_get_gro_max_size() helper which returns the maximum IPv4 or IPv6 GRO size of the netdevice. We later add a netif_get_gso_max_size() equivalent as well for GSO, so that these helpers can be used consistently instead of open-coded checks.

close_range(): fix the logics in descriptor table trimming
Cloning a descriptor table picks the size that would cover all currently opened files. That's fine for clone() and unshare(), but for close_range() there's an additional twist - we clone before we close, and it would be a shame to have close_range(3, ~0U, CLOSE_RANGE_UNSHARE) leave us with a huge descriptor table when we are not going to keep anything past stderr, just because some large file descriptor used to be open before our call has taken it out. Unfortunately, it had been dealt with in an inherently racy way - sane_fdtable_size() gets a "don't copy anything past that" argument (passed via unshare_fd() and dup_fd()), close_range() decides how much should be trimmed and passes that to unshare_fd(). The problem is, a range that used to extend to the end of descriptor table back when close_range() had looked at it might very well have stuff grown after it by the time dup_fd() has allocated a new files_struct and started to figure out the capacity of fdtable to be attached to that. That leads to interesting pathological cases; at the very least it's a QoI issue, since unshare(CLONE_FILES) is atomic in a sense that it takes a snapshot of descriptor table one might have observed at some point. Since CLOSE_RANGE_UNSHARE close_range() is supposed to be a combination of unshare(CLONE_FILES) with plain close_range(), ending up with a weird state that would never occur with unshare(2) is confusing, to put it mildly. It's not hard to get rid of - all it takes is passing both ends of the range down to sane_fdtable_size(). There we are under ->files_lock, so the race is trivially avoided. So we do the following: * switch close_files() from calling unshare_fd() to calling dup_fd(). * undo the calling convention change done to unshare_fd() in |

x86:
* KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or deleted.
The former does not have particularly noticeable overhead, but Intel's
TDX will require the guest to re-accept private pages if they are
dropped from the secure EPT, which is a non starter. Actually,
the only reason why this is not already being done is a bug which
was never fully investigated and caused VM instability with assigned
GeForce GPUs, so allow userspace to opt into the new behavior.
* Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
functionality that is on the horizon).
* Rework common MSR handling code to suppress errors on userspace accesses to
unsupported-but-advertised MSRs. This will allow removing (almost?) all of
KVM's exemptions for userspace access to MSRs that shouldn't exist based on
the vCPU model (the actual cleanup is non-trivial future work).
* Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
stores the entire 64-bit value at the ICR offset.
* Fix a bug where KVM would fail to exit to userspace if one was triggered by
a fastpath exit handler.
* Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
there's already a pending wake event at the time of the exit.
* Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
(the SHUTDOWN hits the VM altogether, not the nested guest)
* Overhaul the "unprotect and retry" logic to more precisely identify cases
where retrying is actually helpful, and to harden all retry paths against
putting the guest into an infinite retry loop.
* Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
the shadow MMU.
* Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for
adding multi generation LRU support in KVM.
* Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled,
i.e. when the CPU has already flushed the RSB.
* Trace the per-CPU host save area as a VMCB pointer to improve readability
and cleanup the retrieval of the SEV-ES host save area.
* Remove unnecessary accounting of temporary nested VMCB related allocations.
* Set FINAL/PAGE in the page fault error code for EPT violations if and only
if the GVA is valid. If the GVA is NOT valid, there is no guest-side page
table walk and so stuffing paging related metadata is nonsensical.
* Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
emulating posted interrupt delivery to L2.
* Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.
* Harden eVMCS loading against an impossible NULL pointer deref (really truly
should be impossible).
* Minor SGX fix and a cleanup.
* Misc cleanups
Generic:
* Register KVM's cpuhp and syscore callbacks when enabling virtualization in
hardware, as the sole purpose of said callbacks is to disable and re-enable
virtualization as needed.
* Enable virtualization when KVM is loaded, not right before the first VM
is created. Together with the previous change, this simplifies a
lot the logic of the callbacks, because their very existence implies
virtualization is enabled.
* Fix a bug that results in KVM prematurely exiting to userspace for coalesced
MMIO/PIO in many cases, clean up the related code, and add a testcase.
* Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_
the gpa+len crosses a page boundary, which thankfully is guaranteed to not
happen in the current code base. Add WARNs in more helpers that read/write
guest memory to detect similar bugs.
Selftests:
* Fix a goof that caused some Hyper-V tests to be skipped when run on bare
metal, i.e. NOT in a VM.
* Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.
* Explicitly include one-off assets in .gitignore. Past Sean was completely
wrong about not being able to detect missing .gitignore entries.
* Verify userspace single-stepping works when KVM happens to handle a VM-Exit
in its fastpath.
* Misc cleanups
