mm/kfence: fix KASAN hardware tag faults during late enablement
When KASAN hardware tags are enabled, re-enabling KFENCE late (via
/sys/module/kfence/parameters/sample_interval) causes KASAN faults.
This happens because the KFENCE pool and metadata are allocated via the
page allocator, which tags the memory, while KFENCE continues to access it
using untagged pointers during initialization.
Use __GFP_SKIP_KASAN for late KFENCE pool and metadata allocations to
ensure the memory remains untagged, consistent with early allocations from
memblock. To support this, add __GFP_SKIP_KASAN to the allowlist in
__alloc_contig_verify_gfp_mask().

mm/damon/core: disallow non-power of two min_region_sz
DAMON core uses min_region_sz parameter value as the DAMON region
alignment. The alignment is made using ALIGN() and ALIGN_DOWN(), which
support only the power of two alignments. But DAMON core API callers can
set min_region_sz to an arbitrary number. Users can also set it
indirectly, using addr_unit.
When the alignment is not properly set, DAMON behavior becomes difficult
to expect and understand, makes it effectively broken. It doesn't cause a
kernel crash-like significant issue, though.
Fix the issue by disallowing min_region_sz input that is not a power of
two. Add the check to damon_commit_ctx(), as all DAMON API callers who
set min_region_sz uses the function.
This can be a sort of behavioral change, but it does not break users, for
the following reasons. As the symptom is making DAMON effectively broken,
it is not reasonable to believe there are real use cases of non-power of
two min_region_sz. There is no known use case or issue reports from the
setup, either.
In future, if we find real use cases of non-power of two alignments and we
can support it with low enough overhead, we can consider moving the
restriction. But, for now, simply disallowing the corner case should be
good enough as a hot fix.

Squashfs: check metadata block offset is within range
Syzkaller reports a "general protection fault in squashfs_copy_data"
This is ultimately caused by a corrupted index look-up table, which
produces a negative metadata block offset.
This is subsequently passed to squashfs_copy_data (via
squashfs_read_metadata) where the negative offset causes an out of bounds
access.
The fix is to check that the offset is within range in
squashfs_read_metadata. This will trap this and other cases.

liveupdate: luo_file: remember retrieve() status
LUO keeps track of successful retrieve attempts on a LUO file. It does so
to avoid multiple retrievals of the same file. Multiple retrievals cause
problems because once the file is retrieved, the serialized data
structures are likely freed and the file is likely in a very different
state from what the code expects.
The retrieve boolean in struct luo_file keeps track of this, and is passed
to the finish callback so it knows what work was already done and what it
has left to do.
All this works well when retrieve succeeds. When it fails,
luo_retrieve_file() returns the error immediately, without ever storing
anywhere that a retrieve was attempted or what its error code was. This
results in an errored LIVEUPDATE_SESSION_RETRIEVE_FD ioctl to userspace,
but nothing prevents it from trying this again.
The retry is problematic for much of the same reasons listed above. The
file is likely in a very different state than what the retrieve logic
normally expects, and it might even have freed some serialization data
structures. Attempting to access them or free them again is going to
break things.
For example, if memfd managed to restore 8 of its 10 folios, but fails on
the 9th, a subsequent retrieve attempt will try to call
kho_restore_folio() on the first folio again, and that will fail with a
warning since it is an invalid operation.
Apart from the retry, finish() also breaks. Since on failure the
retrieved bool in luo_file is never touched, the finish() call on session
close will tell the file handler that retrieve was never attempted, and it
will try to access or free the data structures that might not exist, much
in the same way as the retry attempt.
There is no sane way of attempting the retrieve again. Remember the error
retrieve returned and directly return it on a retry. Also pass this
status code to finish() so it can make the right decision on the work it
needs to do.
This is done by changing the bool to an integer. A value of 0 means
retrieve was never attempted, a positive value means it succeeded, and a
negative value means it failed and the error code is the value.

mm: thp: deny THP for files on anonymous inodes
file_thp_enabled() incorrectly allows THP for files on anonymous inodes
(e.g. guest_memfd and secretmem). These files are created via
alloc_file_pseudo(), which does not call get_write_access() and leaves
inode->i_writecount at 0. Combined with S_ISREG(inode->i_mode) being
true, they appear as read-only regular files when
CONFIG_READ_ONLY_THP_FOR_FS is enabled, making them eligible for THP
collapse.
Anonymous inodes can never pass the inode_is_open_for_write() check
since their i_writecount is never incremented through the normal VFS
open path. The right thing to do is to exclude them from THP eligibility
altogether, since CONFIG_READ_ONLY_THP_FOR_FS was designed for real
filesystem files (e.g. shared libraries), not for pseudo-filesystem
inodes.
For guest_memfd, this allows khugepaged and MADV_COLLAPSE to create
large folios in the page cache via the collapse path, but the
guest_memfd fault handler does not support large folios. This triggers
WARN_ON_ONCE(folio_test_large(folio)) in kvm_gmem_fault_user_mapping().
For secretmem, collapse_file() tries to copy page contents through the
direct map, but secretmem pages are removed from the direct map. This
can result in a kernel crash:
BUG: unable to handle page fault for address: ffff88810284d000
RIP: 0010:memcpy_orig+0x16/0x130
Call Trace:
collapse_file
hpage_collapse_scan_file
madvise_collapse
Secretmem is not affected by the crash on upstream as the memory failure
recovery handles the failed copy gracefully, but it still triggers
confusing false memory failure reports:
Memory failure: 0x106d96f: recovery action for clean unevictable
LRU page: Recovered
Check IS_ANON_FILE(inode) in file_thp_enabled() to deny THP for all
anonymous inode files.

that does not use all the arguments, leading to a harmless warning:

Replace the macro with an inline function so the compiler can see how the
argument would be used, but is still able to optimize out the assignments.

mm/kfence: disable KFENCE upon KASAN HW tags enablement
KFENCE does not currently support KASAN hardware tags. As a result, the
two features are incompatible when enabled simultaneously.
Given that MTE provides deterministic protection and KFENCE is a
sampling-based debugging tool, prioritize the stronger hardware
protections. Disable KFENCE initialization and free the pre-allocated
pool if KASAN hardware tags are detected to ensure the system maintains
the security guarantees provided by MTE.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate

add default_gfp() helper macro and use it in the new *alloc_obj() helpers
Most simple allocations use GFP_KERNEL, and with the new allocation
helpers being introduced, let's just take advantage of that to simplify
that default case.
It's a numbers game:
git grep 'alloc_obj(' |
sed 's/.*\(GFP_[_A-Z]*\).*/\1/' |
sort | uniq -c | sort -n | tail
shows that about 90% of all those new allocator instances just use that
standard GFP_KERNEL.
Those helpers are already macros, and we can easily just make it be the
default case when the gfp argument is missing.
And yes, we could do that for all the legacy interfaces too, but let's
keep it to just the new ones at least for now, since those all got
converted recently anyway, so this is not any "extra" noise outside of
that limited conversion.
And, in fact, I want to do this before doing the -rc1 release, exactly
so that we don't get extra merge conflicts.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

spi: Fixes for v7.0 merge window

Tracing fixes for 7.0:
- Fix possible dereference of uninitialized pointer When validating the persistent ring buffer on boot up, if the first validation fails, a reference to "head_page" is performed in the error path, but it skips over the initialization of that variable. Move the initialization before the first validation check. - Fix use of event length in validation of persistent ring buffer On boot up, the persistent ring buffer is checked to see if it is valid by several methods. One being to walk all the events in the memory location to make sure they are all valid. The length of the event is used to move to the next event. This length is determined by the data in the buffer. If that length is corrupted, it could possibly make the next event to check located at a bad memory location. Validate the length field of the event when doing the event walk. - Fix function graph on archs that do not support use of ftrace_ops When an architecture defines HAVE_DYNAMIC_FTRACE_WITH_ARGS, it means that its function graph tracer uses the ftrace_ops of the function tracer to call its callbacks. This allows a single registered callback to be called directly instead of checking the callback's meta data's hash entries against the function being traced. For architectures that do not support this feature, it must always call the loop function that tests each registered callback (even if there's only one). The loop function tests each callback's meta data against its hash of functions and will call its callback if the function being traced is in its hash map. The issue was that there was no check against this and the direct function was being called even if the architecture didn't support it. This meant that if function tracing was enabled at the same time as a callback was registered with the function graph tracer, its callback would be called for every function that the function tracer also traced, even if the callback's meta data only wanted to be called back for a small subset of functions. Prevent the direct calling for those architectures that do not support it. - Fix references to trace_event_file for hist files The hist files used event_file_data() to get a reference to the associated trace_event_file the histogram was attached to. This would return a pointer even if the trace_event_file is about to be freed (via RCU). Instead it should use the event_file_file() helper that returns NULL if the trace_event_file is marked to be freed so that no new references are added to it. - Wake up hist poll readers when an event is being freed When polling on a hist file, the task is only awoken when a hist trigger is triggered. This means that if an event is being freed while there's a task waiting on its hist file, it will need to wait until the hist trigger occurs to wake it up and allow the freeing to happen. Note, the event will not be completely freed until all references are removed, and a hist poller keeps a reference. But it should still be woken when the event is being freed. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaZd4ExQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqX5AP4powfnNnRfLSKH9idhTp+ltmJ+9roy L7kWTr/z20S2VQEAk331PNZ32uZu+/ZUETYpgtEx4SbRGZFehTBv1ddjfw4= =TWj5 -----END PGP SIGNATURE----- Merge tag 'trace-v7.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix possible dereference of uninitialized pointer When validating the persistent ring buffer on boot up, if the first validation fails, a reference to "head_page" is performed in the error path, but it skips over the initialization of that variable.
