git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf
Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net. This batches
fixes for real crashes with trivial/correctness fixes. There is too
a rework of the conntrack expectation timeout strategy to deal with
a possible race when removing an expectation.
1) Fix the incorrect flowtable timeout extension for entries in
hw offload, from Adrian Bente. This is correcting a defect in
the functionality, no crash.
2) Hold reference to device under the fake dst in br_netfilter,
from Haoze Xie. This is fixing a possible UaF if the device
is removed while packet is sitting in nfqueue.
3) Reject template conntrack in xt_cluster, otherwise access to
uninitialize conntrack fields are possible leading to WARN_ON
due to unset layer 3 protocol. From Wyatt Feng.
4) Make sure the IPv6 tunnel header is in the linear skb data
area before pulling. While at it remove incomplete NEXTHDR_DEST
support. From Lorenzo Bianconi. This possibly leading to crash
if IPv4 header is not in the linear area.
5) Use test_bit_acquire in ipset hash set to avoid reordering
of subsequent memory access. This is addressing a LLM related
report, no crash has been observed. From Jozsef Kadlecsik.
6) Use test_bit_acquire in ipset bitmap set too, for the same
reason as in the previous patch, from Jozsef Kadlecsik.
7) Call kfree_rcu() after rcu_assign_pointer() to address a
possible UaF if kfree_rcu() runs inmediately, which to my
understanding never happens. Never observed in practise,
reported by LLM. Also from Jozsef Kadlecsik.
8) Use disable_delayed_work_sync() instead cancel_delayed_work_sync()
to avoid that ipset GC handler re-queues work as reported by LLM.
From Jozsef Kadlecsik. This is for correctness.
9) Restore the check in nft_payload for exceeding payloda offset
over 2^16. From Florian Westphal. This fixes a silent truncation,
not a big deal, but better be assertive and reject it.
10) Validate NFT_META_BRI_IIFHWADDR can only run from bridge
prerouting. From Florian Westphal. Harmless but it could allow
to read bytes from skb->cb.
11) Zero out destination hardware address during the flowtable
path setup, also from Florian. This is a correctness fix, LLM
points that possible infoleak can happen but topology to achieve
it is not clear.
12) Skip IPv4 options if present when building the IPV4 reject reply.
Otherwise bytes in the IPv4 options header can be sent back to
origin where the ICMP header is being expected. Again from
Florian Westphal.
13) Replace timer API for expectation by GC worker approach. This
is implicitly fixing a race between nf_ct_remove_expectations()
which might fail to remove the expectation due to timer_del()
returning false because timer has expired and callback is
being run concurrently. This fix is addressing a crash that has
been already reported with a reproducer.
14) Check if br_vlan_get_pvid_rcu() fails, otherwise possible stack
infoleak of 4-bytes. From Florian Westphal.

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull more slab updates from Vlastimil Babka:
- Introduce and wire up a new alloc_flags parameter for modifying
slab-specific behavior without adding or reusing gfp flags. Also
introduce slab_alloc_context to keep function parameter bloat in
check. Both are similar to what the page allocator does.
kmalloc_flags() exposes alloc_flags for mm-internal users.
- SLAB_ALLOC_NOLOCK flag is used to implement kmalloc_nolock()
behavior without relying on lack of __GFP_RECLAIM, which caused
false positives with workarounds like fd3634312a04 ("debugobject:
Make it work with deferred page initialization - again").
- SLAB_ALLOC_NO_RECURSE replaces __GFP_NO_OBJ_EXT, which could have
been removed, but pending memory allocation profiling changes in
mm tree have grown a new user - there is however a work ongoing
to replace that too, so __GFP_NO_OBJ_EXT should eventually be
removed. (Vlastimil Babka)

net tree (Pedro Falcato)

kmalloc_flex() in metadata_dst_alloc() sets __counted_by for the
structure to the options_len, which is then initialized to zero.
Later, we're initializing the structure by copying the tunnel info
together with the options, and this triggers a warning for a potential
memcpy overflow, since the compiler estimates that the options can't
fit into the structure, even though the memory for them is actually
allocated.
memcpy: detected buffer overflow: 104 byte write of buffer size 96
WARNING: CPU: X PID: Y at lib/string_helpers.c:1036 __fortify_report
skb_tunnel_info_unclone+0x179/0x190
geneve_xmit+0x7fe/0xe00
The issue is triggered when built with clang and source fortification.
Fix that by doing the copy in two stages: first - the main data with
the options_len, then the options. This way the correct length should
be known at the time of the copy.
It would be better if the options_len never changed after allocation,
but the allocation code is a little separate from the initialization
and it would be awkward and potentially dangerous to return a struct
with options_len set to a non-zero value from the metadata_dst_alloc().
Another option would be to use ip_tunnel_info_opts_set(), but it is
doing too many unnecessary operations for the use case here.

- Continuous reads in general have also been enhanced/fixed for
avoiding potential issues at probe time and at block boundaries
SPI NOR changes:
- Big set of cleanups and improvements to the locking support.
This series contains some cleanups and bug fixes for code and
documentation around write protection. Then support is added for
complement locking, which allows finer grained configuration of
what is considered locked and unlocked. Then complement locking is

- Fix die erase support on Spansion flashes.
Die erase is only supported on multi-die flashes, but the die erase
opcode was set for all. When the opcode is set, it overrides the
default chip erase opcode which should be used for single-die
flashes. Only set the opcode on multi-die flashes. Also, the opcode
was not set on multi-die s28hx-t flashes. Set it so they can use
die-erase correctly

This reverts commit 7b32f64bc512b40b268776c5ac4d354b325b3197.
This patch caused a significant performance regression, so revert it, and
we can determine whether the approach is sensible or not moving forwards,
and if so how to avoid this.
There was a merge conflict with commit de97ae6222c1 ("mm/readahead: no
PG_readahead on EOF"), care was taken to ensure that the revert retained
the behaviour of this patch and cleanly reverts commit 7b32f64bc512 ("mm:
limit filemap_fault readahead to VMA boundaries") only.

After READ_ONLY_THP_FOR_FS is removed, FS either supports large folio or
not. folio_split() can be used on a FS with large folio support without
worrying about getting a THP on a FS without large folio support.
When READ_ONLY_THP_FOR_FS was present, a PMD large pagecache folio can
appear in a FS without large folio support after khugepaged or
madvise(MADV_COLLAPSE) creates it. During truncate_inode_partial_folio(),
such a PMD large pagecache folio is split and if the FS does not support
large folio, it needs to be split to order-0 ones and could not be split
non uniformly to ones with various orders. try_folio_split_to_order() was
added to handle this situation by checking folio_check_splittable(...,
SPLIT_TYPE_NON_UNIFORM) to detect if the large folio is created due to
READ_ONLY_THP_FOR_FS and the FS does not support large folio. Now
READ_ONLY_THP_FOR_FS is removed, all large pagecache folios are created
with FSes supporting large folio, this function is no longer needed and
all large pagecache folios can be split non uniformly.

filemap_nr_thps*() are removed, the related field, address_space->nr_thps,
is no longer needed. Remove it. This shrinks struct address_space by 8
bytes on 64-bit systems which may increase the number of inodes we can
cache.

They are used by READ_ONLY_THP_FOR_FS to handle writes to FSes without
large folio support, so that read-only THPs created in these FSes are not
seen by the FSes when the underlying fd becomes writable. Now read-only
PMD THPs only appear in a FS with large folio support and the supported
orders include PMD_ORDER.
READ_ONLY_THP_FOR_FS was using mapping->nr_thps, inode->i_writecount, and
smp_mb() to prevent writes to a read-only THP and collapsing writable
folios into a THP. In collapse_file(), mapping->nr_thps is increased,
then smp_mb(), and if inode->i_writecount > 0, collapse is stopped, while
do_dentry_open() first increases inode->i_writecount, then a full memory
fence, and if mapping->nr_thps > 0, all read-only THPs are truncated.
Now this mechanism can be removed along with READ_ONLY_THP_FOR_FS code,
since a dirty folio check has been added after try_to_unmap() in
collapse_file() to prevent dirty folios from being collapsed as clean.

Remove the READ_ONLY_THP_FOR_FS gate and khugepaged for file-backed
pmd-sized hugepages are enabled by the global transparent hugepage
control. khugepaged can still be enabled by per-size control for anon and
shmem when the global control is off.
Add shmem_hpage_pmd_enabled() stub for !CONFIG_SHMEM to remove
IS_ENABLED(SHMEM) in hugepage_enabled().
Clean up hugepage_enabled() by moving anon code to anon_hpage_enabled().

Patch series "Remove CONFIG_READ_ONLY_THP_FOR_FS and enable file THP for
writable files", v6.
This patch (of 14):
collapse_file() requires FSes supporting large folio with at least
PMD_ORDER, so replace the READ_ONLY_THP_FOR_FS check with that.
MADV_COLLAPSE ignores shmem huge config, so exclude the check for shmem.
While at it, replace VM_BUG_ON with VM_WARN_ON_ONCE.
Add a helper function mapping_pmd_folio_support() for FSes supporting
large folio with at least PMD_ORDER.

Add three new mTHP statistics to track collapse failures for different
orders when encountering swap PTEs, excessive none PTEs, and shared PTEs:
- collapse_exceed_swap_pte: Increment when mTHP collapse fails due to
encountering a swap PTE.
- collapse_exceed_none_pte: Counts when mTHP collapse fails due to
exceeding the none PTE threshold for the given order
- collapse_exceed_shared_pte: Counts when mTHP collapse fails due to
encountering a shared PTE.
These statistics complement the existing THP_SCAN_EXCEED_* events by
providing per-order granularity for mTHP collapse attempts. The stats are
exposed via sysfs under
`/sys/kernel/mm/transparent_hugepage/hugepages-*/stats/` for each
supported hugepage size.
As we currently do not support collapsing mTHPs that contain a swap or
shared entry, those statistics keep track of how often we are encountering
failed mTHP collapses due to these restrictions.
We will add support for mTHP collapse for anonymous pages next; lets also
track when this happens at the PMD level within the per-mTHP stats.

Letting a function argument indicate whether a lock or unlock operation
should be performed is incompatible with compile-time analysis of locking
operations by sparse and Clang. Hence, split codetag_lock_module_list()
into two functions: a function that locks cttype->mod_lock and another
function that unlocks cttype->mod_lock. No functionality has been
changed. See also commit 916cc5167cc6 ("lib: code tagging framework").

Pages allocated before page_ext is available have their codetag left
uninitialized. Track these early PFNs and clear their codetag in
clear_early_alloc_pfn_tag_refs() to avoid "alloc_tag was not set" warnings
when they are freed later.
Currently a fixed-size array of 8192 entries is used, with a warning if
the limit is exceeded. However, the number of early allocations depends
on the number of CPUs and can be larger than 8192.
Replace the fixed-size array with a dynamically allocated linked list of
pfn_pool structs. Each node is allocated via alloc_page() and mapped to a
pfn_pool containing a next pointer, an atomic slot counter, and a PFN
array that fills the remainder of the page.
The tracking pages themselves are allocated via alloc_page(), which would
trigger __pgalloc_tag_add() -> alloc_tag_add_early_pfn() and recurse
indefinitely. Introduce __GFP_NO_CODETAG (reuses the %__GFP_NO_OBJ_EXT
bit) and pass gfp_flags through pgalloc_tag_add() so that the early path
can skip recording allocations that carry this flag.
