net: xilinx: axienet: Fix Tx skb circular buffer occupancy check in dmaengine xmit
In Dmaengine flow, driver maintains struct skbuf_dma_descriptor rings each
element of which corresponds to a skb. In Tx datapath, compare available
space in skb ring with number of skbs instead of skb fragments.
Replace x * (MAX_SKB_FRAGS) in netif_txq_completed_wake() and
netif_txq_maybe_stop() with x * (1 skb) to fix the comparison.

crypto: shash - Fix buffer overrun in import function
Only set the partial block length to zero if the algorithm is
block-only. Otherwise the descriptor context could be empty,
e.g., for digest_null.

Locking changes for v6.16:
Futexes:
- Add support for task local hash maps (Sebastian Andrzej Siewior,
Peter Zijlstra)
- Implement the FUTEX2_NUMA ABI, which feature extends the futex
interface to be NUMA-aware. On NUMA-aware futexes a second u32
word containing the NUMA node is added to after the u32 futex value
word. (Peter Zijlstra)
- Implement the FUTEX2_MPOL ABI, which feature extends the futex
interface to be mempolicy-aware as well, to further refine futex
node mappings and lookups. (Peter Zijlstra)
Locking primitives:
- Misc cleanups (Andy Shevchenko, Borislav Petkov, Colin Ian King,
Ingo Molnar, Nam Cao, Peter Zijlstra)
Lockdep:
- Prevent abuse of lockdep subclasses (Waiman Long)
- Add number of dynamic keys to /proc/lockdep_stats (Waiman Long)
Plus misc cleanups and fixes.
Note that the tree includes the following dependent out-of-subsystem
changes as well:
- rcuref: Provide rcuref_is_dead()
- mm: Add vmalloc_huge_node()
- mm: Add the mmap_read_lock guard to <linux/mmap_lock.h>

&chan->lock is not supposed to protect 'chan->mbox'. And in __mbox_bind_client, try_module_get is also not protected by &chan->lock. So move module_put out of the lock protected region. Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Jassi Brar <jassisinghbrar@gmail.com> |

mailbox: mtk-cmdq: Refine GCE_GCTL_VALUE setting
Add cmdq_gctl_value_toggle() to configure GCE_CTRL_BY_SW and GCE_DDR_EN
together in the same GCE_GCTL_VALUE register.
For the SoCs whose GCE is located in MMINFRA and uses MMINFRA_AO power,
this allows it to be written without enabling the clocks. Otherwise, all
GCE registers should be written after the GCE clocks are enabled.
Move this function into cmdq_runtime_resume() and cmdq_runtime_suspend()
to ensure it is called when the GCE clock is enabled.

mailbox: imx: Fix TXDB_V2 sending
i.MX95 features several processing domains, Cortex-M7, Cortex-A55
secure, Cortex-A55 non-secure. Each domain could communicate with
SCMI firmware with a dedicated MU. But the current NXP SCMI firmware
is not a RTOS, all processing logic codes are in interrupt context.
So if high priority Cortex-M7 is communicating with SCMI firmware and
requires a bit more time to handle the SCMI call, Linux MU TXDB_V2
will be timeout with high possiblity in 1000us(the current value in
imx-mailbox.c). Per NXP SCMI firmware design, if timeout, there is
no recover logic, so SCMI agents should never timeout and always
wait until the check condition met.
Based on the upper reason, enlarge the timeout value to 10ms which
is less chance to timeout, and retry if timeout really happends.

x86/tdx: mark tdh_vp_enter() as __flatten
In some cases tdx_tdvpr_pa() is not fully inlined into tdh_vp_enter(), which
causes the following warning:
vmlinux.o: warning: objtool: tdh_vp_enter+0x8: call to tdx_tdvpr_pa() leaves .noinstr.text section
This happens if the compiler considers tdx_tdvpr_pa() to be "large", for example
because CONFIG_SPARSEMEM adds two function calls to page_to_section() and
__section_mem_map_addr():
({ const struct page *__pg = (pg); \
int __sec = page_to_section(__pg); \
(unsigned long)(__pg - __section_mem_map_addr(__nr_to_section(__sec)));
\
})
Because exiting the noinstr section is a no-no, just mark tdh_vp_enter() for
full inlining.

replace strncpy with strscpy_pad
The strncpy() function is actively dangerous to use since it may not NULL-terminate the destination string, resulting in potential memory content exposures, unbounded reads, or crashes.

fscrypt update for 6.16
Add support for "hardware-wrapped inline encryption keys" to fscrypt. When enabled on supported platforms, this feature protects file contents keys from certain attacks, such as cold boot attacks. This feature uses the block layer support for wrapped keys which was merged in 6.15. Wrapped key support has existed out-of-tree in Android for a long time, and it's finally ready for upstream now that there is a platform on which it works end-to-end with upstream. Specifically, it works on the Qualcomm SM8650 HDK, using the Qualcomm ICE (Inline Crypto Engine) and HWKM (Hardware Key Manager). The corresponding driver support is included in the SCSI tree for 6.16. Validation for this feature includes two new tests that were already merged into xfstests (generic/368 and generic/369). -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaDNaqxQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOK1K7AP92naB88sRzH1KG7Oic9+dMK+PImARP f15ebG2TzQ3qBgEAreqtNmtCNOH7pguYsTeAcX3Y243vzIkwkDRGk7k+aAI= =P6Sj -----END PGP SIGNATURE----- Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/linux Pull fscrypt update from Eric Biggers: "Add support for 'hardware-wrapped inline encryption keys' to fscrypt.

KVM/arm64 updates for 6.16
* New features:
- Add large stage-2 mapping support for non-protected pKVM guests,
clawing back some performance.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and
protected modes.
- Enable nested virtualisation support on systems that support it
(yes, it has been a long time coming), though it is disabled by
default.
* Improvements, fixes and cleanups:
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. This ensures correctness of
emulation (the data is automatically extracted from the published
JSON files), and helps dealing with the evolution of the
architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS

Merge tag 'kvmarm-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 updates for 6.16
* New features:
- Add large stage-2 mapping support for non-protected pKVM guests,
clawing back some performance.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and
protected modes.
- Enable nested virtualisation support on systems that support it
(yes, it has been a long time coming), though it is disabled by
default.
* Improvements, fixes and cleanups:
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. This ensures correctness of
emulation (the data is automatically extracted from the published
JSON files), and helps dealing with the evolution of the
architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.

net/mlx5_core: Add error handling inmlx5_query_nic_vport_qkey_viol_cntr()
The function mlx5_query_nic_vport_qkey_viol_cntr() calls the function
mlx5_query_nic_vport_context() but does not check its return value. This
could lead to undefined behavior if the query fails. A proper
implementation can be found in mlx5_nic_vport_query_local_lb().
Add error handling for mlx5_query_nic_vport_context(). If it fails, free
the out buffer via kvfree() and return error code.

Pull erofs updates from Gao Xiang:
"In this cycle, Intel QAT hardware accelerators are supported to
improve DEFLATE decompression performance. I've tested it with the
enwik9 dataset of 1 MiB pclusters on our Intel Sapphire Rapids
bare-metal server and a PL0 ESSD, and the sequential read performance
even surpasses LZ4 software decompression on this setup.
In addition, a `fsoffset` mount option is introduced for file-backed
mounts to specify the filesystem offset in order to adapt customized
container formats.
And other improvements and minor cleanups. Summary:
- Add a `fsoffset` mount option to specify the filesystem offset
- Support Intel QAT accelerators to boost up the DEFLATE algorithm
- Initialize per-CPU workers and CPU hotplug hooks lazily to avoid
unnecessary overhead when EROFS is not mounted
- Fix file handle encoding for 64-bit NIDs

net: lan966x: Fix 1-step timestamping over ipv4 or ipv6
When enabling 1-step timestamping for ptp frames that are over udpv4 or
udpv6 then the inserted timestamp is added at the wrong offset in the
frame, meaning that will modify the frame at the wrong place, so the
frame will be malformed.
To fix this, the HW needs to know which kind of frame it is to know
where to insert the timestamp. For that there is a field in the IFH that
says the PDU_TYPE, which can be NONE which is the default value,
IPV4 or IPV6. Therefore make sure to set the PDU_TYPE so the HW knows
where to insert the timestamp.
Like I mention before the issue is not seen with L2 frames because by
default the PDU_TYPE has a value of 0, which represents the L2 frames.

bcachefs updates for 6.16
Lots of changes:
- Poisoned extents can now be moved: this lets us handle bitrotted data
without deleting it. For now, reading from poisoned extents only
returns -EIO: in the future we'll have an API for specifying "read
this data even if there were bitflips".
- Incompatible features may now be enabled at runtime, via
"opts/version_upgrade" in sysfs. Toggle it to incompatible, and then
toggle it back - option changes via the sysfs interface are
persistent.
- Various changes to support deployable disk images:
- RO mounts now use less memory
- Images may be stripped of alloc info, particularly useful for
slimming them down if they will primarily be mounted RO. Alloc info
will be automatically regenerated on first RW mount, and this is
quite fast.
- Filesystem images generated with 'bcachefs image' will be
automatically resized the first time they're mounted on a larger
device.
The images 'bcachefs image' generates with compression enabled have
been comparable in size to those generated by squashfs and erofs -
but you get a full RW capable filesystem.
- Major error message improvements for btree node reads, data reads,
and elsewhere. We now build up a single error message that lists all
the errors encountered, actions taken to repair, and success/failure
of the IO. This extends to other error paths that may kick off other
actions, e.g. scheduling recovery passes: actions we took because of
an error are included in that error message, with grouping/indentation
so we can see what caused what.
- Repair/self healing:
- We can now kick off recovery passes and run them in the background
if we detect errors. Currently, this is just used by code that walks
backpointers; we now also check for missing backpointers at runtime
and run check_extents_to_backpointers if required. The messy 6.14
upgrade left missing backpointers for some users, and this will
correct that automatically instead of requiring a manual fsck - some
users noticed this as copygc spinning and not making progress.
In the future, as more recovery passes come online, we'll be able to
repair and recover from nearly anything - except for unreadable
btree nodes, and that's why you're using replication, of course -
without shutting down the filesystem.
- There's a new recovery pass, for checking the rebalance_work btree,
which tracks extents that rebalance will process later.
- Hardening:
- Close the last known hole in btree iterator/btree locking
assertions: path->should_be_locked paths must stay locked until the
end of the transaction. This shook out a few bugs, including a
performance issue that was causing unnecessary path_upgrade
transaction restarts.
- Performance;
- Faster snapshot deletion: this is an incompatible feature, as it
requires new sentinal values, for safety. Snapshot deletion no
longer has to do a full metadata scan, it now just scans the inodes
btree: if an extent/dirent/xattr is present for a given snapshot ID,
we already require that an inode be present with that same snapshot
ID.
If/when users hit scalability limits again (ridiculously huge
filesystems with lots of inodes, and many sparse snapshots), let me
know - the next step will be to add an index from snapshot ID ->
inode number, which won't be too hard.
- Faster device removal: the "scan for pointers to this device" no
longer does a full metadata scan, instead it walks backpointers.
Like fast snapshot deletion this is another incompat feature: it
also requires a new sentinal value, because we don't want to reuse
these device IDs until after a fsck.
- We're now coalescing redundant accounting updates prior to
transaction commit, taking some pressure off the journal. Shortly
we'll also be doing multiple extent updates in a transaction in the
main write path, which combined with the previous should drastically
cut down on the amount of metadata updates we have to journal.
- Stack usage improvements: All allocator state has been moved off the
stack
- Debug improvements:
- enumerated refcounts: The debug code previously used for filesystem
write refs is now a small library, and used for other heavily used
refcounts. Different users of a refcount are enumerated, making it
much easier to debug refcount issues.
- Async object debugging: There's a new kconfig option that makes
various async objects (different types of bios, data updates, write
ops, etc.) visible in debugfs, and it should be fast enough to leave
on in production.
- Various sets of assertions no longer require CONFIG_BCACHEFS_DEBUG,
instead they're controlled by module parameters and static keys,
meaning users won't need to compile custom kernels as often to help
debug issues.
- bch2_trans_kmalloc() calls can be tracked (there's a new kconfig
option); with it on you can check the btree_transaction_stats in
debugfs to see the bch2_trans_kmalloc() calls a transaction did when
it used the most memory.
