Pull vmescape mitigation fixes from Dave Hansen:
"Mitigate vmscape issue with indirect branch predictor flushes.
vmscape is a vulnerability that essentially takes Spectre-v2 and
attacks host userspace from a guest. It particularly affects
hypervisors like QEMU.
Even if a hypervisor may not have any sensitive data like disk
encryption keys, guest-userspace may be able to attack the
guest-kernel using the hypervisor as a confused deputy.
There are many ways to mitigate vmscape using the existing Spectre-v2
defenses like IBRS variants or the IBPB flushes. This series focuses
solely on IBPB because it works universally across vendors and all
vulnerable processors. Further work doing vendor and model-specific
optimizations can build on top of this if needed / wanted.
Do the normal issue mitigation dance:
- Add the CPU bug boilerplate
- Add a list of vulnerable CPUs
- Use IBPB to flush the branch predictors after running guests"

Florian Westpha says:
====================
netfilter pull request nf-25-09-10
First patch adds a lockdep annotation for a false-positive splat.
Last patch adds formal reviewer tag for Phil Sutter to MAINTAINERS.
Rest of the patches resolve spurious false negative results during set
lookups while another CPU is processing a transaction.
This has been broken at least since v4.18 when an unconditional
synchronize_rcu call was removed from the commit phase of nf_tables.
Quoting from Stefan Hanreichs original report:
It seems like we've found an issue with atomicity when reloading
nftables rulesets. Sometimes there is a small window where rules
containing sets do not seem to apply to incoming traffic, due to the set
apparently being empty for a short amount of time when flushing / adding
elements.
Exanple ruleset:
table ip filter {
set match {
type ipv4_addr
flags interval
elements = { 0.0.0.0-192.168.2.19, 192.168.2.21-255.255.255.255 }
}
chain pre {
type filter hook prerouting priority filter; policy accept;
ip saddr @match accept
counter comment "must never match"
}
}
Reproducer transaction:
while true:
nft -f -<<EOF
flush set ip filter match
create element ip filter match { \
0.0.0.0-192.168.2.19, 192.168.2.21-255.255.255.255 }
EOF
done
Then create traffic. to/from e.g. 192.168.2.1 to 192.168.3.10.
Once in a while the counter will increment even though the
'ip saddr @match' rule should have accepted the packet.
See individual patches for details.
Thanks to Stefan Hanreich for an initial description and reproducer for
this bug and to Pablo Neira Ayuso for reviewing earlier iterations of
the patchset.

In C, enumerated types do not have a defined size, apart from being
compatible with one of the standard types. This allows an ABI /
compiler to choose the type of an enum depending on the values it
needs to store, and storing larger values in it can lead to undefined
behaviour.
The tx_type and rx_filters members of struct kernel_ethtool_ts_info
are defined as enumerated types, but are bit arrays, where each bit
is defined by the enumerated type. This means they typically store
values in excess of the maximum value of the enumerated type, in
fact (1 << max_value) and thus must not be declared using the
enumated type.
Fix both of these to use u32, as per the corresponding __u32 UAPI type.

This function was added for retpoline mitigation and is replaced by a
static inline helper if mitigations are not enabled.
Enable this helper function unconditionally so next patch can add a lookup
restart mechanism to fix possible false negatives while transactions are
in progress.
Adding lookup restarts in nft_lookup_eval doesn't work as nft_objref would
then need the same copypaste loop.
This patch is separate to ease review of the actual bug fix.

This will soon be read from packet path around same time as the gencursor.
Both gencursor and base_seq get incremented almost at the same time, so
it makes sense to place them in the same structure.
This doesn't increase struct net size on 64bit due to padding.

The intel_pstate driver manages CPU capacity changes itself and it does
not need an update of the capacity of all CPUs in the system to be
carried out after registering a PD.
Moreover, in some configurations (for instance, an SMT-capable
hybrid x86 system booted with nosmt in the kernel command line) the
em_check_capacity_update() call at the end of em_dev_register_perf_domain()
always fails and reschedules itself to run once again in 1 s, so
effectively it runs in vain every 1 s forever.
To address this, introduce a new variant of em_dev_register_perf_domain(),
called em_dev_register_pd_no_update(), that does not invoke
em_check_capacity_update(), and make intel_pstate use it instead of the
original.

Clang 22 recently added support for defining __SANITIZE__ macros similar
to GCC [1], which causes warnings (or errors with CONFIG_WERROR=y or W=e)
with the existing defines that the kernel creates to emulate this behavior
with existing clang versions.
In file included from <built-in>:3:
In file included from include/linux/compiler_types.h:171:
include/linux/compiler-clang.h:37:9: error: '__SANITIZE_THREAD__' macro redefined [-Werror,-Wmacro-redefined]
37 | #define __SANITIZE_THREAD__
| ^
<built-in>:352:9: note: previous definition is here
352 | #define __SANITIZE_THREAD__ 1
| ^
Refactor compiler-clang.h to only define the sanitizer macros when they
are undefined and adjust the rest of the code to use these macros for
checking if the sanitizers are enabled, clearing up the warnings and
allowing the kernel to easily drop these defines when the minimum
supported version of LLVM for building the kernel becomes 22.0.0 or newer.

kasan_populate_vmalloc() and its helpers ignore the caller's gfp_mask and
always allocate memory using the hardcoded GFP_KERNEL flag. This makes
them inconsistent with vmalloc(), which was recently extended to support
GFP_NOFS and GFP_NOIO allocations.
Page table allocations performed during shadow population also ignore the
external gfp_mask. To preserve the intended semantics of GFP_NOFS and
GFP_NOIO, wrap the apply_to_page_range() calls into the appropriate
memalloc scope.
xfs calls vmalloc with GFP_NOFS, so this bug could lead to deadlock.
There was a report here
https://lkml.kernel.org/r/686ea951.050a0220.385921.0016.GAE@google.com
This patch:
- Extends kasan_populate_vmalloc() and helpers to take gfp_mask;
- Passes gfp_mask down to alloc_pages_bulk() and __get_free_page();
- Enforces GFP_NOFS/NOIO semantics with memalloc_*_save()/restore()
around apply_to_page_range();
- Updates vmalloc.c and percpu allocator call sites accordingly.

Pull vfs fixes from Christian Brauner:
"fuse:
- Prevent opening of non-regular backing files.
Fuse doesn't support non-regular files anyway.
- Check whether copy_file_range() returns a larger size than
requested.
- Prevent overflow in copy_file_range() as fuse currently only
supports 32-bit sized copies.
- Cache the blocksize value if the server returned a new value as
inode->i_blkbits isn't modified directly anymore.
- Fix i_blkbits handling for iomap partial writes.
By default i_blkbits is set to PAGE_SIZE which causes iomap to mark
the whole folio as uptodate even on a partial write. But fuseblk
filesystems support choosing a blocksize smaller than PAGE_SIZE
risking data corruption. Simply enforce PAGE_SIZE as blocksize for
fuseblk's internal inode for now.
- Prevent out-of-bounds acces in fuse_dev_write() when the number of
bytes to be retrieved is truncated to the fc->max_pages limit.
virtiofs:
- Fix page faults for DAX page addresses.
Misc:
- Tighten file handle decoding from userns.
Check that the decoded dentry itself has a valid idmapping in the
user namespace.
- Fix mount-notify selftests.
- Fix some indentation errors.
- Add an FMODE_ flag to indicate IOCB_HAS_METADATA availability.
This will be moved to an FOP_* flag with a bit more rework needed

This new attribute is supposed to be used instead of NFTA_DEVICE_NAME
for simple wildcard interface specs. It holds a NUL-terminated string
representing an interface name prefix to match on.
While kernel code to distinguish full names from prefixes in
NFTA_DEVICE_NAME is simpler than this solution, reusing the existing
attribute with different semantics leads to confusion between different
versions of kernel and user space though:
* With old kernels, wildcards submitted by user space are accepted yet
silently treated as regular names.
* With old user space, wildcards submitted by kernel may cause crashes
since libnftnl expects NUL-termination when there is none.
Using a distinct attribute type sanitizes these situations as the
receiving part detects and rejects the unexpected attribute nested in
*_HOOK_DEVS attributes.

Followup of commit c51da3f7a161 ("net: remove sock_i_uid()")
A recent syzbot report was the trigger for this change.
Over the years, we had many problems caused by the
read_lock[_bh](&sk->sk_callback_lock) in sock_i_uid().
We could fix smc_diag_dump_proto() or make a more radical move:
Instead of waiting for new syzbot reports, cache the socket
inode number in sk->sk_ino, so that we no longer
need to acquire sk->sk_callback_lock in sock_i_ino().
This makes socket dumps faster (one less cache line miss,
and two atomic ops avoided).
Prior art:
commit 25a9c8a4431c ("netlink: Add __sock_i_ino() for __netlink_diag_dump().")
commit 4f9bf2a2f5aa ("tcp: Don't acquire inet_listen_hashbucket::lock with disabled BH.")

The call to __iter_div_u64_rem() in vdso_time_update_aux() is a wrapper
around subtraction. It cannot be used to divide large numbers, as that
introduces long, computationally expensive delays. A regular u64 division
is also not possible in the timekeeper update path as it can be too slow.
Instead of splitting the ktime_t offset into into second and subsecond
components during the timekeeper update fast-path, do it together with the
adjustment of tk->offs_aux in the slow-path. Equivalent to the handling of
offs_boot and monotonic_to_boot.
Reuse the storage of monotonic_to_boot for the new field, as it is not used
by auxiliary timekeepers.

Introduce and use {pgd,p4d}_populate_kernel() in core MM code when
populating PGD and P4D entries for the kernel address space. These
helpers ensure proper synchronization of page tables when updating the
kernel portion of top-level page tables.
Until now, the kernel has relied on each architecture to handle
synchronization of top-level page tables in an ad-hoc manner. For
example, see commit 9b861528a801 ("x86-64, mem: Update all PGDs for direct
mapping and vmemmap mapping changes").
However, this approach has proven fragile for following reasons:
1) It is easy to forget to perform the necessary page table
synchronization when introducing new changes.
For instance, commit 4917f55b4ef9 ("mm/sparse-vmemmap: improve memory
savings for compound devmaps") overlooked the need to synchronize
page tables for the vmemmap area.
2) It is also easy to overlook that the vmemmap and direct mapping areas
must not be accessed before explicit page table synchronization.
For example, commit 8d400913c231 ("x86/vmemmap: handle unpopulated
sub-pmd ranges")) caused crashes by accessing the vmemmap area
before calling sync_global_pgds().
To address this, as suggested by Dave Hansen, introduce _kernel() variants
of the page table population helpers, which invoke architecture-specific
hooks to properly synchronize page tables. These are introduced in a new
header file, include/linux/pgalloc.h, so they can be called from common
code.
They reuse existing infrastructure for vmalloc and ioremap.
Synchronization requirements are determined by ARCH_PAGE_TABLE_SYNC_MASK,
and the actual synchronization is performed by
arch_sync_kernel_mappings().
This change currently targets only x86_64, so only PGD and P4D level
helpers are introduced. Currently, these helpers are no-ops since no
architecture sets PGTBL_{PGD,P4D}_MODIFIED in ARCH_PAGE_TABLE_SYNC_MASK.
In theory, PUD and PMD level helpers can be added later if needed by other
architectures. For now, 32-bit architectures (x86-32 and arm) only handle
PGTBL_PMD_MODIFIED, so p*d_populate_kernel() will never affect them unless
we introduce a PMD level helper.

During our internal testing, we started observing intermittent boot
failures when the machine uses 4-level paging and has a large amount of
persistent memory:

</TASK>
It turns out that the kernel panics while initializing vmemmap (struct
page array) when the vmemmap region spans two PGD entries, because the new
PGD entry is only installed in init_mm.pgd, but not in the page tables of
other tasks.
And looking at __populate_section_memmap():
if (vmemmap_can_optimize(altmap, pgmap))
// does not sync top level page tables
r = vmemmap_populate_compound_pages(pfn, start, end, nid, pgmap);
else
// sync top level page tables in x86
r = vmemmap_populate(start, end, nid, altmap);
In the normal path, vmemmap_populate() in arch/x86/mm/init_64.c
synchronizes the top level page table (See commit 9b861528a801 ("x86-64,
mem: Update all PGDs for direct mapping and vmemmap mapping changes")) so
that all tasks in the system can see the new vmemmap area.
However, when vmemmap_can_optimize() returns true, the optimized path
skips synchronization of top-level page tables. This is because
vmemmap_populate_compound_pages() is implemented in core MM code, which
does not handle synchronization of the top-level page tables. Instead,
the core MM has historically relied on each architecture to perform this
synchronization manually.
We're not the first party to encounter a crash caused by not-sync'd top
level page tables: earlier this year, Gwan-gyeong Mun attempted to address
the issue [1] [2] after hitting a kernel panic when x86 code accessed the
vmemmap area before the corresponding top-level entries were synced. At
that time, the issue was believed to be triggered only when struct page
was enlarged for debugging purposes, and the patch did not get further
updates.
It turns out that current approach of relying on each arch to handle the
page table sync manually is fragile because 1) it's easy to forget to sync
the top level page table, and 2) it's also easy to overlook that the
kernel should not access the vmemmap and direct mapping areas before the
sync.
# The solution: Make page table sync more code robust and harder to miss
To address this, Dave Hansen suggested [3] [4] introducing
{pgd,p4d}_populate_kernel() for updating kernel portion of the page tables
and allow each architecture to explicitly perform synchronization when
installing top-level entries. With this approach, we no longer need to
worry about missing the sync step, reducing the risk of future
regressions.
The new interface reuses existing ARCH_PAGE_TABLE_SYNC_MASK,
PGTBL_P*D_MODIFIED and arch_sync_kernel_mappings() facility used by
vmalloc and ioremap to synchronize page tables.
pgd_populate_kernel() looks like this:
static inline void pgd_populate_kernel(unsigned long addr, pgd_t *pgd,
p4d_t *p4d)
{
pgd_populate(&init_mm, pgd, p4d);
if (ARCH_PAGE_TABLE_SYNC_MASK & PGTBL_PGD_MODIFIED)
arch_sync_kernel_mappings(addr, addr);
}
It is worth noting that vmalloc() and apply_to_range() carefully
synchronizes page tables by calling p*d_alloc_track() and
arch_sync_kernel_mappings(), and thus they are not affected by this patch
series.
This series was hugely inspired by Dave Hansen's suggestion and hence
added Suggested-by: Dave Hansen.
Cc stable because lack of this series opens the door to intermittent
boot failures.
This patch (of 3):
Move ARCH_PAGE_TABLE_SYNC_MASK and arch_sync_kernel_mappings() to
linux/pgtable.h so that they can be used outside of vmalloc and ioremap.
