commit a7318172aa332a161fb9618286e64454c827f8fd
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/18798
CVE: CVE-2026-89746
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
When two hist triggers on different events are registered with the same
name=, the second one reuses the first as named_data. Both are added to
tr->hist_vars by save_hist_vars() during event_hist_trigger_parse(),
because save_hist_vars() is called before event_trigger_register() while
the named reuse is only detected later, in hist_register_trigger().
In the named-data branch hist_register_trigger() then frees the second
histogram's hist_data via destroy_hist_data(), but never removes its
tr->hist_vars list entry, leaving a dangling pointer and leaking the
trace_array reference it holds.
A later hist trigger that references a variable makes find_var_file()
walk tr->hist_vars and dereference the freed hist_data. The bug is
reproducible from userspace by writing three hist triggers to tracefs:
cd /sys/kernel/tracing
echo 'hist:keys=common_pid:x=common_pid:name=mh' > events/sched/sched_switch/trigger
echo 'hist:keys=common_pid:x=common_pid:name=mh' > events/sched/sched_process_fork/trigger
echo 'hist:keys=common_pid:vals=$x' > events/sched/sched_process_exit/trigger
The third write panics the kernel:

CVE: CVE-2026-89618
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
eventfs_create_dir() allocates the eventfs_inode and initializes it with
init_ei(). But this does not initialize the eventfs_inode list_heads. If
the eventfs_create_dir() fails due to memory pressure, it will call
free_ei() before it initialized the lists, and that checks to make sure
the eventfs_inode has no children. But because the list wasn't
initialized, it will give a false warning.
Fix it by moving the list initialization into init_ei().

commit 0895a0c0734703be5532f3883c42db95615fd98b
category: bugfix
bugzilla: https://atomgit.com/openeuler/kernel/issues/9949
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
map_check_btf() allows a key-less BTF (btf_key_type_id == 0) only for
maps that have a ->map_check_btf callback, and leaves the actual
decision to that callback. Hash maps used to have no ->map_check_btf,
so a key-less BTF was rejected outright.
That changed when htab and rhtab gained a ->map_check_btf to register a
dtor - htab in commit 1df97a7453ee ("bpf: Register dtor for freeing
special fields") and rhtab in commit 6905f8601298 ("bpf: Allow special
fields in resizable hashtab"). Neither looks at the key, so a key-less
hash map now passes map_check_btf() and gets created. Reading it back
through bpffs feeds the key type_id 0 into btf_type_seq_show();
btf_type_by_id() returns the void type, kind_ops[BTF_KIND_UNKN] is NULL,
and btf_type_show() dereferences it:

------------------------------
[ Upstream commit 440915499231e9db1c361aa45bb702e8fd3b4a32 ]
dmaengine_terminate_all() does not wait for a running callback, so the TX
callback can still touch the TX buffer after it is freed. The RX poll
timer reads the RX buffers without the port lock.
Switch to dmaengine_terminate_sync() and delete the RX timer before
freeing the buffers.

Background
==========
On x86, the resctrl allows creating up to num_rmids monitoring groups
under parent control group. However, ARM64 MPAM is currently limited by
the PMG (Performance Monitoring Group) count, which is typically much
smaller than the theoretical RMID limit. This creates a significant
scalability gap: users expecting fine-grained per-process or per-thread
monitoring quickly exhaust the PMG space, even when plenty of reqPARTIDs
remain available.
The Narrow-PARTID feature, defined in the ARM MPAM architecture,
addresses this by associating reqPARTIDs with intPARTIDs through a
programmable many-to-one mapping. This allows the kernel to present more
logical monitoring contexts.
Design Overview
===============
The implementation extends the RMID encoding to carry reqPARTID
information:
RMID = reqPARTID * NUM_PMG + PMG
In this patchset, a monitoring group is uniquely identified by the
combination of reqPARTID and PMG. The closid is represented by intPARTID,
which is exactly the original PARTID.
For systems with homogeneous MSCs (all supporting Narrow-PARTID), the
driver exposes the full reqPARTID range directly. For heterogeneous
systems where some MSCs lack Narrow-PARTID support, the driver utilizes
PARTIDs beyond the intPARTID range as reqPARTIDs to expand monitoring
capacity. The sole exception is when MBA MSCs lack Narrow-PARTID support,
their percentage-based control mechanism prevents the use of PARTIDs as
reqPARTIDs.
Capacity Improvements
=====================
--------------------------------------------------------------------------
The maximum | Sub-monitoring groups | System-wide
number of | under a control group | monitoring groups
--------------------------------------------------------------------------
Without | |
reqPARTID | PMG | intPARTID * PMG
--------------------------------------------------------------------------
reqPARTID | |
static allocation | (reqPARTID // intPARTID) * PMG | reqPARTID * PMG
--------------------------------------------------------------------------
reqPARTID | |
dynamic allocation | (reqPARTID − intPARTID + 1) * PMG | reqPARTID * PMG
--------------------------------------------------------------------------
Under MPAM, the number of reqPARTID is always greater than or equal to
intPARTID.

LeapIO inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/9945
------------------------------------------
leapraid driver changes from v2.00.01.02 to v2.00.01.10.
This update includes:
- AI-assisted code inspection rollout and follow-up bug fixes
- Clang, Sparse, and Smatch issue cleanup
- recovery-wait and nested hard-reset stabilization
- SCSI EH, task-management, and AER recovery fixes
- timeout, IOC-fault, and I/O diagnostic improvements
- MSI-X/IRQ affinity and sparse-CPU mapping fixes
- SAS topology, event bitmap, and VPHY handling fixes
- async-event and SMP payload validation hardening
- ioctl and passthrough bounds-checking cleanup
- adapter-removal and firmware-event race fixes
- firmware-log mmap lifetime and reference-count fixes
- active-command teardown and IRQ synchronization
- probe rollback and host-memory cleanup hardening
- config-page stack usage reduction
- SMART polling and NCQ sysfs alignment
- drive matching and adapter metadata cleanup

[PATCH openEuler-1.0-LTS] ipvlan: inherit needed_headroom and needed_tailroom from phy_dev

commit e16e960d55a40d36bd7c2494cc005e757dc9a1ef
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/18377
CVE: CVE-2026-74744
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
ipvlan devices inherit hard_header_len from phy_dev during ipvlan_init(),
but leave needed_headroom and needed_tailroom set to 0.
When the underlying phy_dev (or stacked lower device) requires extra headroom
or tailroom for headers/trailers (e.g. macsec, ipsec, wireguard, tunnels, or
veth with rx headroom), upper layers calculating packet headroom and tailroom
fail to reserve sufficient space.
This can result in reallocation overhead, skb headroom underflows, or KASAN
slab-use-after-free crashes when dev_hard_header() / ipvlan_hard_header()
prepends header data or when lower devices append tailroom.
Fix this by:
1. Inheriting needed_headroom and needed_tailroom from phy_dev in ipvlan_init().
2. Propagating needed_headroom and needed_tailroom updates to attached ipvlans
in ipvlan_device_event() when receiving NETDEV_FEAT_CHANGE events.
Fixes: 2ad7bf363841 ("ipvlan: Initial check-in of the IPVLAN driver.")
