xen/privcmd: fix double free via VMA splitting
privcmd_vm_ops defines .close (privcmd_close), but neither .may_split
nor .open. When userspace does a partial munmap() on a privcmd mapping,
the kernel splits the VMA via __split_vma(). Since may_split is NULL,
the split is allowed. vm_area_dup() copies vm_private_data (a pages
array allocated in alloc_empty_pages()) into the new VMA without any
fixup, because there is no .open callback.
Both VMAs now point to the same pages array. When the unmapped portion
is closed, privcmd_close() calls:
- xen_unmap_domain_gfn_range()
- xen_free_unpopulated_pages()
- kvfree(pages)
The surviving VMA still holds the dangling pointer. When it is later
destroyed, the same sequence runs again, which leads to a double free.
Fix this issue by adding a .may_split callback denying the VMA split.
This is XSA-487 / CVE-2026-31787

Buffer overflow in drivers/xen/sys-hypervisor.c
The build id returned by HYPERVISOR_xen_version(XENVER_build_id) is
neither NUL terminated nor a string.
The first causes a buffer overflow as sprintf in buildid_show will
read and copy till it finds a NUL.
00000000 f4 91 51 f4 dd 38 9e 9d 65 47 52 eb 10 71 db 50 |..Q..8..eGR..q.P|
00000010 b9 a8 01 42 6f 2e 32 |...Bo.2|
00000017
So use a memcpy instead of sprintf to have the correct value:
00000000 f4 91 51 f4 dd 00 9e 9d 65 47 52 eb 10 71 db 50 |..Q.....eGR..q.P|
00000010 b9 a8 01 42 |...B|
00000014
(the above have a hack to embed a zero inside and check it's
returned correctly).
This is XSA-485 / CVE-2026-31786

tracefs fixes for v7.1:
- Use list_add_tail_rcu() for walking eventfs children The children link list is protected by SRCU and list walkers can walk the list with only using SRCU. Using just list_add_tail() on weakly ordered architectures can cause issues. Instead use list_add_tail_rcu(). - Hold eventfs_mutex and SRCU for remount walk events The trace_apply_options() walks the tracefs_inodes where some are eventfs inodes and eventfs_remount() is called which in turn calls eventfs_set_attr(). This walk only holds normal RCU read locks, but the eventfs_mutex and SRCU should be held.

ktest updates for v7.1:
- Fix month in date timestamp used to create failure directories On failure, a directory is created to store the logs and config file to analyze the failure. The Perl function localtime is used to create the data timestamp of the directory. The month passed back from that function starts at 0 and not 1, but the timestamp used does not account for that. Thus for April 20, 2026, the timestamp of 20260320 is used, instead of 20260420. - Save the logfile to the failure directory Just the test log is saved to the directory on failure, but there's useful information in the full logfile that can be helpful to analyzing the failure.

ring-buffer fix for v7.1
- Make undefsyms_base.c into a real file The file undefsyms_base.c is used to catch any symbols used by a remote ring buffer that is made for use of a pKVM hypervisor.

x86/hyperv: Skip LP/VP creation on kexec
After a kexec the logical processors and virtual processors already exist in the hypervisor because they were created by the previous kernel. Attempting to add them again causes either a BUG_ON or corrupted VP state leading to MCEs in the new kernel. Add hv_lp_exists() to probe whether an LP is already present by calling HVCALL_GET_LOGICAL_PROCESSOR_RUN_TIME. When it succeeds the LP exists and we skip the add-LP and create-VP loops entirely. Also add hv_call_notify_all_processors_started() which informs the hypervisor that all processors are online. This is required after adding LPs (fresh boot) and is a no-op on kexec since we skip that path.

Drivers: hv: vmbus: fix hyperv_cpuhp_online variable shadowing
vmbus_alloc_synic_and_connect() declares a local 'int
hyperv_cpuhp_online' that shadows the file-scope global of the same
name. The cpuhp state returned by cpuhp_setup_state() is stored in
the local, leaving the global at 0 (CPUHP_OFFLINE). When
hv_kexec_handler() or hv_machine_shutdown() later call
cpuhp_remove_state(hyperv_cpuhp_online) they pass 0, which hits the
BUG_ON in __cpuhp_remove_state_cpuslocked().
Remove the local declaration so the cpuhp state is stored in the
file-scope global where hv_kexec_handler() and hv_machine_shutdown()
expect it.

Probes fixes for v7.1
- fprobe: Fixed several bugs, which includes followings:
. Prevention of re-registration: Added an earlier check to reject
re-registering an already active fprobe before its state is modified
during the initialization phase.
. Robustness in failure paths:
- Ensured fprobes are correctly removed from all internal tables and
properly RCU-freed during registration failure.
- Modified unregister_fprobe() to proceed with unregistration even if
temporary memory allocation fails.
. RCU safety in module unloading: Avoided a potential "sleep in RCU"
warning by removing a kcalloc() call in the module notifier path. This
also tries to remove fprobe_hash_node even if memory allocation fails.
. Type-aware unregistration: Fixed a bug where unregistering an fprobe
did not account for different types (entry-only vs. entry-exit) at the
same address, which previously left "junk" entries in the underlying
ftrace/fgraph ops.
. Unregistration of empty ftrace_ops: Avoided unneeded performance
overhead because of making registered ftrace_ops empty (means trace
all functions.) This counts remaining entries and unregister ftrace_ops
when it becomes empty.
- ftracetest: In addition to the fix, two new selftests to check above
fixes, are included:
. Module Unloading Test: Specifically verifies that fprobe events on
a module are correctly cleaned up and do not trigger "trace-all"
behavior when the module is removed.
. Multiple Fprobe Events Test: Ensures that having multiple fprobes on
the same function correctly manages the ftrace hash map during
removal.

Pull probes fixes from Masami Hiramatsu:
"fprobe bug fixes:
- Prevent re-registration
Add an earlier check to reject re-registering an already active
fprobe before its state is modified during the initialization phase
- Robustness in failure paths:
- Ensure fprobes are correctly removed from all internal tables
and properly RCU-freed during registration failure
- Make unregister_fprobe() proceed with unregistration even if
temporary memory allocation fails
- RCU safety in module unloading
Avoid a potential "sleep in RCU" warning by removing a kcalloc()
call in the module notifier path. This also tries to remove
fprobe_hash_node even if memory allocation fails.
- Type-aware unregistration
Fix a bug where unregistering an fprobe did not account for
different types (entry-only vs entry-exit) at the same address,
which previously left "junk" entries in the underlying
ftrace/fgraph ops
- Unregistration of empty ftrace_ops
Avoid unneeded performance overhead due to making registered
ftrace_ops empty - which means 'trace all functions'. This counts
remaining entries and unregister ftrace_ops when it becomes empty.
Two new selftests to check above fixes:
- Module Unloading Test:
Specifically verifies that fprobe events on a module are correctly
cleaned up and do not trigger 'trace-all' behavior when the module
is removed.
- Multiple Fprobe Events Test:
Ensure that having multiple fprobes on the same function correctly
manages the ftrace hash map during removal"

tracing/fprobe: Fix to unregister ftrace_ops if it is empty on module unloading
Fix fprobe to unregister ftrace_ops if corresponding type of fprobe does not exist on the fprobe_ip_table and it is expected to be empty when unloading modules. Since ftrace thinks that the empty hash means everything to be traced, if we set fprobes only on the unloaded module, all functions are traced unexpectedly after unloading module. e.g. # modprobe xt_LOG.ko # echo 'f:test log_tg*' > dynamic_events # echo 1 > events/fprobes/test/enable # cat enabled_functions log_tg [xt_LOG] (1) tramp: 0xffffffffa0004000 (fprobe_ftrace_entry+0x0/0x490) ->fprobe_ftrace_entry+0x0/0x490 log_tg_check [xt_LOG] (1) tramp: 0xffffffffa0004000 (fprobe_ftrace_entry+0x0/0x490) ->fprobe_ftrace_entry+0x0/0x490 log_tg_destroy [xt_LOG] (1) tramp: 0xffffffffa0004000 (fprobe_ftrace_entry+0x0/0x490) ->fprobe_ftrace_entry+0x0/0x490 # rmmod xt_LOG # wc -l enabled_functions 34085 enabled_functions Link: https://lore.kernel.org/all/177669368776.132053.10042301916765771279.stgit@mhiramat.tok.corp.google.com/ Signed-off-by: Masami Hiramatsu (Google) <mhiramat@kernel.org> |

We've finally gotten rid of the struct clk_ops::round_rate() code after months
of effort from Brian Masney. Now the only option is to use determine_rate(),
which is good because that takes a struct argument instead of just a couple
unsigned longs, allowing us to easily modify the way we determine and set rates
in the clk tree.
Beyond that core framework change we've got the typical pile of new SoC clk
driver additions, fixes for clk data and/or adding missing clks because the
consumer driver using those clks wasn't ready, etc. The usual suspects are all
here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
driver side of this looks pretty normal.
Core:
- Remove the round_rate() clk op (yay!)
New Drivers:
- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for
the Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller
support for the Qualcomm Nord platform
- GPU clock controller support for Qualcomm SM8750
- Video and GPU clock controller support for Qualcomm Glymur
- Global clock controller support for Qualcomm IPQ5210
- Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
controllers on the SoC
- ExynosAutov920: Add G3D (GPU) clock controller
- Clock driver for the Rockchip RV1103B SoC
- Initial support for the Renesas RZ/G3L (R9A08G046) SoC
- Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"We've finally gotten rid of the struct clk_ops::round_rate() code
after months of effort from Brian Masney. Now the only option is to
use determine_rate(), which is good because that takes a struct
argument instead of just a couple unsigned longs, allowing us to
easily modify the way we determine and set rates in the clk tree.
Beyond that core framework change we've got the typical pile of new
SoC clk driver additions, fixes for clk data and/or adding missing
clks because the consumer driver using those clks wasn't ready, etc.
The usual suspects are all here: Qualcomm, Samsung, Mediatek, and
Rockchip along with some newcomers making RISC-V SoCs like ESWIN's
eic700 and Tenstorrent's Atlantis. The clk driver side of this looks
pretty normal.
Core:
- Remove the round_rate() clk op (yay!)
New Drivers:
- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for the
Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller support
for the Qualcomm Nord platform
- GPU clock controller support for Qualcomm SM8750
- Video and GPU clock controller support for Qualcomm Glymur
- Global clock controller support for Qualcomm IPQ5210
- Axis ARTPEC-9: Add new PLL clocks and new drivers for eight clock
controllers on the SoC
- ExynosAutov920: Add G3D (GPU) clock controller
- Clock driver for the Rockchip RV1103B SoC
- Initial support for the Renesas RZ/G3L (R9A08G046) SoC
- Clock and reset controllers (e.g. PRCM) in the Tenstorrent Atlantis SoC"

tracing/fprobe: Avoid kcalloc() in rcu_read_lock section
fprobe_remove_node_in_module() is called under RCU read locked, but
this invokes kcalloc() if there are more than 8 fprobes installed
on the module. Sashiko warns it because kcalloc() can sleep [1].

To fix this issue, expand the batch size to 128 and do not expand
the fprobe_addr_list, but just cancel walking on fprobe_ip_table,
update fgraph/ftrace_ops and retry the loop again.

tracing/fprobe: Remove fprobe from hash in failure path
When register_fprobe_ips() fails, it tries to remove a list of
fprobe_hash_node from fprobe_ip_table, but it missed to remove
fprobe itself from fprobe_table. Moreover, when removing
the fprobe_hash_node which is added to rhltable once, it must
use kfree_rcu() after removing from rhltable.
To fix these issues, this reuses unregister_fprobe() internal
code to rollback the half-way registered fprobe.

tracing/fprobe: Unregister fprobe even if memory allocation fails
unregister_fprobe() can fail under memory pressure because of memory
allocation failure, but this maybe called from module unloading, and
usually there is no way to retry it. Moreover. trace_fprobe does not
check the return value.
To fix this problem, unregister fprobe and fprobe_hash_node even if
working memory allocation fails.
Anyway, if the last fprobe is removed, the filter will be freed.

tracing/fprobe: Reject registration of a registered fprobe before init
Reject registration of a registered fprobe which is on the fprobe
hash table before initializing fprobe.
The add_fprobe_hash() checks this re-register fprobe, but since
fprobe_init() clears hlist_array field, it is too late to check it.
It has to check the re-registration before touncing fprobe.

Fixing livelocks in shrink_dcache_tree()
If shrink_dcache_tree() finds a dentry in the middle of being killed by another thread, it has to wait until the victim finishes dying, gets detached from the tree and ceases to pin its parent. The way we used to deal with that amounted to busy-wait; unfortunately, it's not just inefficient but can lead to reliably reproducible hard livelocks. Solved by having shrink_dentry_tree() attach a completion to such dentry, with dentry_unlist() calling complete() on all objects attached to it. With a bit of care it can be done without growing struct dentry or adding overhead in normal case.

erofs: unify lcn as u64 for 32-bit platforms
As sashiko reported [1], `lcn` was typed as `unsigned long` (or
`unsigned int` sometimes), which is only 32 bits wide on 32-bit
platforms, which causes `(lcn << lclusterbits)` to be truncated
at 4 GiB.
In order to consolidate the logic, just use `u64` consistently
around the codebase.

erofs: fix offset truncation when shifting pgoff on 32-bit platforms
On 32-bit platforms, pgoff_t is 32 bits wide, so left-shifting large arbitrary pgoff_t values by PAGE_SHIFT performs 32-bit arithmetic and silently truncates the result for pages beyond the 4 GiB boundary. Cast the page index to loff_t before shifting to produce a correct 64-bit byte offset. Fixes: |

erofs: fix the out-of-bounds nameoff handling for trailing dirents
Currently we already have boundary-checks for nameoffs, but the trailing dirents are special since the namelens are calculated with strnlen() with unchecked nameoffs. If a crafted EROFS has a trailing dirent with nameoff >= maxsize, maxsize - nameoff can underflow, causing strnlen() to read past the directory block. nameoff0 should also be verified to be a multiple of `sizeof(struct erofs_dirent)` as well [1].

tracing: tell git to ignore the generated 'undefsyms_base.c' file
This odd file was added to automatically figure out tool-generated
symbols.
Honestly, it *should* have been just a real honest-to-goodness regular
file in git, instead of having strange code to generate it in the
Makefile, but that is not how that silly thing works. So now we need to
ignore it explicitly.

"The main 'feature' is a workaround for C1-Pro erratum 4193714
requiring IPIs during TLB maintenance if a process is running in user
space with SME enabled.
The hardware acknowledges the DVMSync messages before completing
in-flight SME accesses, with security implications. The workaround
makes use of the mm_cpumask() to track the cores that need
interrupting (arm64 hasn't used this mask before).
The rest are fixes for MPAM, CCA and generated header that turned up

ktest: Fix the month in the name of the failure directory
The Perl localtime() function returns the month starting at 0 not 1. This
caused the date produced to create the directory for saving files of a
failed run to have the month off by one.
machine-test-useconfig-fail-20260314073628
The above happened in April, not March. The correct name should have been:
machine-test-useconfig-fail-20260414073628
This was somewhat confusing.

Merge tag 'leds-next-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds
Pull LED updates from Lee Jones:
Core:
- Implement fallback to software node name for LED names
- Fix formatting issues in `led-core.c` reported by checkpatch.pl
- Make `led_remove_lookup()` NULL-aware
- Switch from `class_find_device_by_of_node()` to
`class_find_device_by_fwnode()`
- Drop the unneeded dependency on `OF_GPIO` from `LEDS_NETXBIG`
in Kconfig
Kinetic KTD2692:
- Make the `ktd2692_timing` variable static to resolve a
sparse warning
LGM SSO:
- Fix a typo in the `GET_SRC_OFFSET` macro
