scripts: coccinelle: devm_free: reduce false positives
False positives could be introduced due to allocations using the new _obj functions. Add these to the "safe" rule accordingly. False positives could also be introduced when the same variable name has two possible types. Incorporate type information to avoid reporting this case This does lead to false negatives when no type information is available.

coccinelle: misc: struct_size: drop unneeded parentheses
The outer parentheses and the single-branch disjunction don't matter when just matching and reporting a line. Eliminating them reduces the complexity of the pattern to match and gives a performance improvement in the non-patch cases, like the previous minmax change.

coccinelle: mini_lock: improve performance when searching loops
The 'looped' rule collects the returns inside a for loop to prevent 'err' from reporting them. It searches every for loop in the file, and on files with large loop bodies the search explodes. For example, kernel/bpf/verifier.c runs for over 200 seconds, almost entirely in 'looped' according to --profile. Since the kernel .cocciconfig sets a 200 second timeout, coccicheck silently skips the file. To avoid this, collect the candidate returns first, so that 'looped' checks only those positions. 'err' then excludes what 'looped' found. Every return that 'err' can report is also a candidate, so the same returns are excluded as before and the output does not change. A report-mode run over every .c file in the tree produces identical output. So verifier.c now finishes well within the timeout, in a few seconds.

coccinelle: api: check for macro context
A cast on a call to an allocation function that is the body of a macro can be useful, as it ensures tha the macro is used for allocating objects of the right type.

coccinelle: misc: minmax: improve performance when no candidate exists
The rules that report an opencoded min() or max() search every function body, even when the file contains nothing to find. To avoid this, collect the candidates first and run the search only when one exists. A candidate is any conditional expression whose condition is a comparison. Every opencoded min() or max() is also a candidate, so the same opportunities are reported as before and the output does not change. A report-mode run over every .c file in the tree produces identical output. Signed-off-by: Sang-Heon Jeon <ekffu200098@gmail.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> |

coccinelle: double_lock: improve performance when no double lock exists
The 'balanced' rule collects the locks that are taken and released under the same condition, to prevent them from being reported as a double lock. It runs on every file that contains a lock call. To avoid this, collect the double-lock candidates first, so that 'balanced' runs only when one exists. The report then excludes what 'balanced' found. Every double lock that can be reported is also a candidate, so the same reports are made as before and the output does not change.

kho: make boot time huge page allocation work nicely with KHO
Today allocation of gigantic pages in HugeTLB cannot work reliably with KHO:
* HugeTLB allocates gigantic pages using memblock and autoscaling of KHO
scratch accounts for these allocations. When gigantic pages occupy half
of the memory of more, KHO fails to allocate its scratch memory.
* After kexec handover, memblock allocations exclusively use KHO scratch
that is not supposed to contain preserved memory. This essentially blocks
preservation of HugeTLB with gigantic pages.
Extend early memory pools available for KHO kernel with areas that are
guaranteed not to contain preserved memory.

This contains a set of 142 SMB server updates focused on SMB2 command
sequencing, SMB3 request replay and encryption, Apple Time Machine
interoperability, protocol-compatibility fixes validated with smbtorture,
security hardening, SMB Direct transport support, connection reliability,
and other correctness improvements.
New features:
- Implement the SMB2 command sequence window.
Enforce the credit-based MessageId range for each connection, rejecting
out-of-window, duplicate, and wrapped sequence numbers. This prevents
invalid requests and same-channel replays from being processed.
- Add SMB3 request replay support.
SMB3 clients may resend requests with SMB2_FLAGS_REPLAY_OPERATION after
a channel disconnect when the original response was lost. Track the
required channel and open state to safely handle durable CREATE replays
and make oplock, lease, and lock replays idempotent, avoiding duplicate
state changes and improving multichannel reconnect reliability.
- Add opt-in Apple Time Machine support.
Implement the AAPL negotiation and related Finder, stream, COPYCHUNK,
sparse-file, CHANGE_NOTIFY, and RPC compatibility required for Time
Machine shares, allowing macOS backupd to use ksmbd for backups.
- Add per-share SMB3 encryption support.
Allow individual shares to require SMB3 encryption by advertising
SMB2_SHAREFLAG_ENCRYPT_DATA in TREE_CONNECT responses and rejecting
unencrypted tree connects and plaintext requests for protected shares.
- Add SMB Direct RDMA encryption support.
Extend SMB Direct to support SMB3 encrypted payloads over RDMA, with
transform negotiation and encryption/decryption for RDMA READ/WRITE.
Other changes:
- Parse and retain AppInstanceVersion contexts, enforce version ordering,
close older active handles for newer takeovers, and reject invalid or
unversioned opens according to the SMB2 semantics.
- Accept durable reconnect requests that omit VolatileFileId when the
persistent ID and reconnect context identify the handle, while
continuing to reject explicit volatile-ID mismatches.
- Fix SMB2/SMB3 protocol validation and security issues, including request
offsets, file and object IDs, IPC responses, output buffer sizes,
SMB3.1.1 binding validation, signing-required handling, durable handles,
ACLs, maximal access, and security information.
- Fix heap out-of-bounds accesses, use-after-free bugs, memory leaks,
invalid pointer dereferences, and sensitive-data lifetime issues in
authentication, Kerberos, preauthentication, sessions, connections,
and module teardown.
- Correct alternate-data-stream and named-stream handling, COPYCHUNK
behavior, sparse-file and compression attributes, allocated-range
queries, file trimming, duplicate extents, DOS attributes, snapshots,
normalized names, and partial information responses.
- Fix locking, lease, oplock, durable reconnect, async request, and
CHANGE_NOTIFY races, including deferred-lock rollback, parent directory
lease notifications, and connection teardown lifetime bugs.
- Fix SMB3 encryption handling for compressed requests, expired encrypted
sessions, interim responses, bound multichannel connections, and
decryption failures.
- Fix SMB3 multichannel session lookup and session state transitions so
changes are scoped to the correct bound connections and cannot revive
connections that are already shutting down.
- Fix DACL access checks so ACE walks are bounded by the declared DACL
size, preventing data beyond the DACL boundary from being interpreted
during access validation.
- Fix session accounting and lifetime issues, including session counter
updates during publication and removal, session leaks on registration
failure, and procfs creation diagnostics.
- Improve TCP connection reliability by enabling TCP keepalive for
accepted connections and preserving TCP timers for kernel sockets,
preventing silent peers from holding connections indefinitely.

Pull smb server updates from Namjae Jeon:
"This contains server updates focused on SMB2 command sequencing, SMB3
request replay and encryption, Apple Time Machine interoperability,
protocol-compatibility fixes validated with smbtorture, security
hardening, SMB Direct transport support, connection reliability, and
other correctness improvements.
New features:
- Implement the SMB2 command sequence window
Enforce the credit-based MessageId range for each connection,
rejecting out-of-window, duplicate, and wrapped sequence numbers.
This prevents invalid requests and same-channel replays from being
processed
- Add SMB3 request replay support
SMB3 clients may resend requests with SMB2_FLAGS_REPLAY_OPERATION
after a channel disconnect when the original response was lost.
Track the required channel and open state to safely handle durable
CREATE replays and make oplock, lease, and lock replays idempotent,
avoiding duplicate state changes and improving multichannel
reconnect reliability
- Add opt-in Apple Time Machine support
Implement the AAPL negotiation and related Finder, stream,
COPYCHUNK, sparse-file, CHANGE_NOTIFY, and RPC compatibility
required for Time Machine shares, allowing macOS backupd to use
ksmbd for backups
- Add per-share SMB3 encryption support
Allow individual shares to require SMB3 encryption by advertising
SMB2_SHAREFLAG_ENCRYPT_DATA in TREE_CONNECT responses and rejecting
unencrypted tree connects and plaintext requests for protected
shares
- Add SMB Direct RDMA encryption support
Extend SMB Direct to support SMB3 encrypted payloads over RDMA,
with transform negotiation and encryption/decryption for RDMA
READ/WRITE
Other changes:
- Parse and retain AppInstanceVersion contexts, enforce version
ordering, close older active handles for newer takeovers, and
reject invalid or unversioned opens according to the SMB2 semantics
- Accept durable reconnect requests that omit VolatileFileId when the
persistent ID and reconnect context identify the handle, while
continuing to reject explicit volatile-ID mismatches
- Fix SMB2/SMB3 protocol validation and security issues, including
request offsets, file and object IDs, IPC responses, output buffer
sizes, SMB3.1.1 binding validation, signing-required handling,
durable handles, ACLs, maximal access, and security information
- Fix heap out-of-bounds accesses, use-after-free bugs, memory leaks,
invalid pointer dereferences, and sensitive-data lifetime issues in
authentication, Kerberos, preauthentication, sessions, connections,
and module teardown
- Correct alternate-data-stream and named-stream handling, COPYCHUNK
behavior, sparse-file and compression attributes, allocated-range
queries, file trimming, duplicate extents, DOS attributes,
snapshots, normalized names, and partial information responses
- Fix locking, lease, oplock, durable reconnect, async request, and
CHANGE_NOTIFY races, including deferred-lock rollback, parent
directory lease notifications, and connection teardown lifetime
bugs
- Fix SMB3 encryption handling for compressed requests, expired
encrypted sessions, interim responses, bound multichannel
connections, and decryption failures
- Fix SMB3 multichannel session lookup and session state transitions
so changes are scoped to the correct bound connections and cannot
revive connections that are already shutting down
- Fix DACL access checks so ACE walks are bounded by the declared
DACL size, preventing data beyond the DACL boundary from being
interpreted during access validation
- Fix session accounting and lifetime issues, including session
counter updates during publication and removal, session leaks on
registration failure, and procfs creation diagnostics
- Improve TCP connection reliability by enabling TCP keepalive for
accepted connections and preserving TCP timers for kernel sockets,
preventing silent peers from holding connections indefinitely
- Fix smbdirect RDMA cleanup ordering for completion queues, QPs,
child sockets, and listener locking
- Improve async response framing, multi-iovec signing, RPC pipe
status handling, and ksmbd procfs monitoring for server, share,
connection, session, and open-file state
- Remove the obsolete DES crypto header and Kconfig dependency now
that NTLMv1 support has been removed
- Update the ksmbd repository URL in MAINTAINERS and add an
additional KSMBD reviewer"

This update includes two minor fixes that have been siting on linux-next
for the past weeks.
- A patch from David removing the normalization function that we no
longer use.
- A patch from me fixing a parsing issue in the encoding version
argument passed by filesystems.

This contains a set of nine exfat fixes covering shared writable mappings,
entry error handling, allocation cleanup, FITRIM bounds, and locking:
- Fix valid_size extension over shared writable mappings by lazily
zeroing page-cache gaps and ensuring racing stores cannot be
overwritten or extend beyond valid_size.
- Clean up partially written directory entries on add-entry failure and
safely free new directory clusters.
- Free a newly allocated directory cluster when zeroing it fails.
- Write the destination entry before removing the source entry during
rename, preserving the source if the destination write fails.
- Keep FITRIM within the requested range, even when the free-space search
wraps around the allocation bitmap.
- Fix truncated FS_IOC_GETFSLABEL results by passing the destination
buffer size in bytes to the UTF-16-to-NLS conversion.
- Fix overflow in the cluster-to-dentry calculation, which could cause
readdir to stop early on large volumes.
- Replace the per-inode truncate_lock with inode_lock, using shared
locking in bmap to serialize against concurrent truncation.
- Update the exfat mailing list address in MAINTAINERS.

perf tools updates for v7.3
perf c2c:
- Add 'function view' in perf c2c report TUI (switched by pressing 'TAB'
in the cacheline view) to organize samples around functions rather than
cachelines in 3-level hierarchy:
Level 1: Read-side function (sorted by estimated Cycles %)
Level 2: Contending writer functions (sorted by Store count)
Level 3: Shared cacheline addresses
Users can navigate the entries and fold/unfold using 'e' key. An example
output would look like below:
Shared Data Functions Table (19 entries, sorted on Cycles %)
Cycles Store
% count Function / Contending function / Cacheline
----------------------------------------------------------------------
+ 35.67% 876 + [k] cpupri_set
+ 24.31% 424 + [k] pull_rt_task
- 16.53% 555 - [k] dequeue_pushable_task
145 - [k] pull_rt_task
145 0xff2d0082809da080
139 - [k] enqueue_pushable_task
70 0xff2d00a2071f9640
69 0xff2d0082809da000
python module support:
- Extend "perf" python module so that it can be fully functional. The goal
is to run scripts directly, not by 'perf script' command. This would give
better performance as well as more control to build standalone programs
with UI.
- Add LiveSession helper (perf_live.py) to enable live event collection
directly from Python using perf.evlist and perf.parse_events.
perf stat:
- Add --hide-zero-events option to suppress zero-count events.
- Reject conflicting --field-separator and --json-output options.
- Fix duplicate event output with --for-each-cgroup.
perf sched latency:
- Add -H/--histogram and --hist-mode (log|linear) options to show scheduler
wait latency histograms.
- Add --time option to filter analysis by time span in 'perf sched latency'.
ARM CoreSight:
- Synthesize callchains for instruction samples from CoreSight trace
using thread stack ('--itrace=g...').
- Support call indentation ('perf script -F +callindent') to display call
depth hierarchy on branch samples.
- Decode ETE (Embedded Trace Extension) exception packets.
Build system:
- Add 'make install-build-deps' target to install required packages.
- Parallelize JSON and metric pre-computation in jevents.py for faster builds.
Vendor event/metric updates:
- Add Intel Nova Lake events and update tables for existing models.
- Update AMD Zen 5 and Zen 6 core events.
- Update Arm64 Tegra410 metrics and PowerPC hcalls.
Internal changes and fixes:
- Harden trace-event and synthetic event parsing against corrupted data.
- Fix unwinding of multi-threaded processes in libdw unwinder.
- Fix memory leaks in various commands and python bindings.
- Speed up 'perf test' shell tests.

firewire updates for v7.3
This update includes error checks, a potential bug fix, and KUnit tests.
Sreeraj S Kurup addressed an error case when generating the contents of
the configuration ROM with parameters supplied by in-kernel
implementations such as unit drivers. Some error checks were added to
handle failures in this path.
Abdun Nihaal identified a potential memory leak when an invalid self-ID
sequence causes an error while building the internal node tree. KUnit
tests have been added to trigger this case. This memory leak has existed
since the first commit and has now been fixed.

- Remove unnecessary module::args. Nowadays, no parameter-handling code points into the module::args buffer. The last user of module::args in xtensa/simdisk is updated and the data is then removed. - Add Rust support for boolean parameters. This will initially be used by the Rust null block driver. - Fix clearing the current charp parameter value when setting a new one fails due to an allocation failure. - Improve the debugging code for kmod (request_module()) duplicates. Fix a potential use-after-free when waiting on a duplicate request and make several general improvements to the code. - Fix the symbol size returned when looking up a data symbol through kallsyms. - The remaining changes are smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQFkBAABCABOFiEEIduBR9MnFA82q/jtumpXJwqY6poFAmqG/rIbFIAAAAAABAAO bWFudTIsMi41KzEuMTIsMiwyFBxwZXRyLnBhdmx1QHN1c2UuY29tAAoJELpqVycK mOqaur8H/i1kJq+zQfUB6/ijvX4yRGXezX0O30iLJ2N/imVsnMe6xP2eqqFIb2Be r5gnCc8P1WRJrDIe3uMsQBpoWIxEpCJ0F+S6JXiFEdht66taco8ivpP4hJWGHerj dCIf7RA3JOFave/7mN4UsrSXtl3HUyrMXplYuycE/5l/pYUY06qXmetgpA2aWywu jVpnCW9I7OO55Tf8tto2X4h6TbXP7ukCnojnadFz+N8JlG2hs45CQYSl1wEzKaFv okqPWCHTexcWySaEbqWWogbzvzIL6lr9C+nKMzYggMDYH7TxMwfscvo4pmTO/nOx +EO4PArCenf+7nsV2wKl2YLbnbzM1oA= =p/Yx -----END PGP SIGNATURE----- Merge tag 'modules-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux Pull module updates from Petr Pavlu: - Remove unnecessary module::args.

The set of eCryptfs changes for the 7.3-rc1 merge window consists of: - Hardening and fixes for maliciously crafted eCryptfs metadata in the lower encrypted file - Hardening and fixes for maliciously crafted userspace <-> kernel miscdev communications - Locking fixes for userspace <-> kernel miscdev communications - Fix to display encrypted filename related mount options - Clean up address_space_operations and reduce build dependencies by moving to filemap_dirty_folio() - Get rid of an unnecessary memory allocation in the inode update path - Kernel-doc formatting corrections The patches have all spent time in linux-next and they pass all tests in the ecryptfs-utils tree. I did manual validation of the miscdev fixes since we don't have test coverage for that feature. -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEKvuQkp28KvPJn/fVfL7QslYSS/0FAmqHmJURHGNvZGVAdHlo aWNrcy5jb20ACgkQfL7QslYSS/3N9Q/+JFdmV0MU5oxbYMorJIfdR6cpRK28OvXN qaLX4wnQO3hvzILQ+GqX9KuFuqrIos3bbJpS5kGFjt2YpmVwFZwdcSQSLrHzxILA 6vexECAUmfJyVJqaraGzReZJYJfn3NBHrO8qizNzeuOGWqmvhSNIV5wi7T2yVaav LspVIjUtxaqHG4Sm2ZkW4Mm9T4wSYWl3QasyyV2Nir+KCdFekQS8GNx7LnkXm2L3 iqiEvijfNyVR4IVNnrzwdozIOqBqP5At4y1Uj+w4N7mjXzVEg158QV7nC1ndttGx z4HuomgQI0Xo61WYmQgb0omC7FIlFD422+nrrK3ZKFz881e1ozKd7hGa3r1gSeP9 lZma2GsQNYojYEWc/TgkyP/U3eUKVYeqmsWIyQjSKe1a1pmITgz8fMUiyegdVOSC Y20AH3fY0f8xRcUGv6BXeUYw4E5bED5Bh8/CgzcUpi5Vc3K3E/yxofrbZAuGJFSl KJ8Mfq9nsdVvuCWga2izglVecMWCjVuqM29yALh3nhmQXwuw6iJCF3Ob27kln97J GLmewNUj1tkhixzoGkx16VxEzrRR+GQoSnpmxXFvAke7EfHYkEQxlKF84phSsYR4 0hhP7EzhkgrNVXB2HB88LPTIBhO4fqoqCKPca33ZC4vMcDGuC4kJvXz/BiaY9CPp Y58PFrWNGjc= =LCDJ -----END PGP SIGNATURE----- Merge tag 'ecryptfs-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs Pull eCryptfs updates from Tyler Hicks: - Hardening and fixes for maliciously crafted eCryptfs metadata in the lower encrypted file - Hardening and fixes for maliciously crafted userspace <-> kernel miscdev communications - Locking fixes for userspace <-> kernel miscdev communications - Fix to display encrypted filename related mount options - Clean up address_space_operations and reduce build dependencies by moving to filemap_dirty_folio() - Get rid of an unnecessary memory allocation in the inode update path - Kernel-doc formatting corrections * tag 'ecryptfs-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: ecryptfs: ecryptfs_kernel.h: clean up kernel-doc comments ecryptfs: use filemap_dirty_folio for address space operations ecryptfs: avoid heap allocation for inode size write ecryptfs: show filename encryption options eCryptfs: bound the packet-length peek to the user buffer ecryptfs: reject too-small tag 70 packets ecryptfs: fix tag 11 packet exact-fit size check ecryptfs: pass packet set buffer size to parser ecryptfs: hold msg ctx list lock when cleaning daemon queue ecryptfs: release message context on send failure ecryptfs: reject oversized encrypted_key_size in parse_tag_3_packet |

SCSI misc on 20260821

drm/xe: Don't hand out the flat CCS storage as usable VRAM
get_flat_ccs_offset() reads the base of the flat CCS storage from the
hardware, scales it by the number of enabled L3 nodes, and rounds the
result up to 128K. Everything below that offset is then handed to the
VRAM allocator as usable memory.
Rounding a limit that means "usable memory ends here" upwards publishes
whatever lies between the real base and the rounded one as free memory,
and that memory belongs to the compression hardware. The scaled value
has no reason to be 128K aligned, and on a Battlemage G21 with 16 GiB it
is not:
flat CCS base: raw 0x3fafff800, rounded 0x3fb000000
so the last 2 KiB of page 0x3fafff000 is CCS storage, in the allocator's
pool. Whatever is allocated there gets that tail overwritten by the
compression hardware, which needs no page-table entry, no buffer object
and no GPU submission to do it, and does it before userspace exists.
On this machine a Mesa VM's level-3 page table landed on that page on
every cold boot. It lost the entry covering the compositor's
batch-buffer heap, so the compositor's first submission faulted fetching
its batch and gdm restarted it forever: a black screen on an otherwise
working machine. Restarting gdm cleared it because the next VM's page
tables were allocated somewhere else.
Round down instead, to the page size the allocator works in. On this
machine that excludes exactly one page.
Reading the reserved page afterwards shows what had been writing it:
[369] 0xcccc000000000000
[371] 0xcc77000000000000
[373] 0xcccc000000000000
[375] 0xcc77000000000000
compression metadata, two bytes per sixteen, sitting where the driver
used to hand out memory.
The assertion that should have caught this compares the offset against
GSMBASE - ccs_size for equality. That value is 128K aligned, so it
agrees with the rounded-up offset precisely when the base is not
aligned - the check cannot fail in the case it exists to catch, and is
compiled out unless CONFIG_DRM_XE_DEBUG is set. Replace it with one
that can fail: CCS storage must not run into GSM.
[ And this was a debug session from hell, enormously helped by an AI
doing much of the grunt-work.
I'd like to call it my tireless helper, but the AI several times
stated flat out that this was impossible and unsolvable and that we
should just write a report about it.
I suspect those things have been trained by people who may not be
quite as stubborn as I am.
But while the AI was ready to give up several times, it did keep
adding debug code and analyzing it faithfully when I pushed. So credit
where credit is due and I let the AI write the commit message above.
This is basically a one-liner fixing a bogus "round_up()" to a
"round_down()", but there were 24 patches adding more and more debug
information to this, and 18 kernel boot to finally narrow it down to
this. - Linus ]
