Right, I couldn't find l.adrp in the kernel's image after compilation. But I
was thinking, in case l.adrp is used somewhere in the future (for e.g. in a
custom kernel module) and a probe is placed at that instruction, we would need
to emulate that instruction. This is because the target address is calculated
using the instruction's address (InsnAddr & -8192). If l.adrp is moved to an
out-of-line slot to single-step for KProbes, the slot's address will be used to
generate the target address instead of the original address.
Since l.adrp is not really used anywhere and it's highly unlikely that it will
be probed, an alternative could be to add l.adrp to the blacklist so that probes
at this instruction are never inserted.

Oh, got it. I hadn't checked those architectures at that point. I was
following the convention in LoongArch and the namespace wasn't there. I'll
revert this change.

Maybe it should be renamed to something that indicates this is related
to probes (I wasn't able to come up with a better name).
The enums are used in a few places in KProbe's implementation to check
if an instruction requires emulation, has been blacklisted, or can be
single-stepped in an out-of-line slot. An alternative would be to use
macros (similar to OPCODE_SYS) but that won't have type checking. Either
way, I think it's better than using raw values in multiple places.
Shall I simply rename the enum type, or shall I switch to macros? What
are your thoughts?

I am not entirely sure why CPUs with no delay slot were not taken into account
initially. The "in_delay_slot" function in traps.c [1] always assumes (for the
case where SPR_SR_DSX is not implemented) that the CPU has a delay slot if PC is
a branch instruction.
Given that the specification allows CPUs not to have a delay slot, I thought I
would include that as well. With no SPR_SR_DSX, if it can be guaranteed that PC
will be a branch instruction only when delay slots are enabled, then there should
be no change in behaviour in "simulate_branch" even with the addition of the
"has_delay_slot" check.
However, if PC can be a branch instruction even when there are no delay slots, then
"simulate_branch" now adds 4 to regs->pc instead of adding 8 unconditionally. Please
correct me if I am wrong.
"has_delay_slot" is particularly important for KProbes, since a probe at a branch
instruction with a delay slot means the branch will have to be emulated followed
by single-stepping of the delay slot instruction.
But if there are no delay slots, then only branch emulation is required.

Yes, I think static keys can be used here. If the more likely case is that a delay
slot exists, we can make that the more likely branch.

"simulate_pc" is used by KProbes for single-stepping l.adrp. At the moment, it's
not being used anywhere else. Maybe I should move this function to the second commit
which has the KProbe changes.
Also, this function can be removed altogether if we choose to blacklist l.adrp.

I am a little confused here. The core of the function was already wrapped in the
"in_delay_slot" check [2]. I moved it to a new file so instruction emulation could be
used in other places as well(e.g., in KProbes). Functionality wise, the function is
still the same with the added feature that it also supports CPUs with no delay slot.

I think that downtime should be accepted as a cost for stability in
general. If your new kernel feature has a bug and causes a crash,
anyway it gets your servers down.

In this case, you can make specific livepatch or kernel module
to replace the kernel function without using BPF on your server.
The BGP trafic in bonding device seems very specific, so it may not
cause a trouble, but this is very generic change, which allows
user to change more core kernel feature, e.g. memory management
or scheduler etc.
Excessive degrees of freedom introduce uncertainty and instability
into a system. While the functionality is interesting, it would be
a way to generalize schedext in an uncontrolled way.
At a minimum, some form of build time and runtime constraint, along
with a taint flag that clearly indicates in the crash logs that this
feature is being used, would be necessary. (It means this is should
not be used in production environment.)

I think we are already sync'd up on this during PUCK, but for the benefit
of others: Sean pointed out that if we don't then we'll need to add yet
another capability so userspace can determine when it can actually do
in-place conversion for SNP.
Right now, this series effectively advertises in place conversion at the
point where KVM_CAP_GUEST_MEMFD_MEMORY_ATTRIBUTES reports
'KVM_MEMORY_ATTRIBUTE_PRIVATE', so I slightly reworked the series to
include the snp_launch_update() change prior to that point in time in
the series. Thanks to prereqs and changes/requirements you've already
pulled in, it's just one additional patch now:
KVM: SEV: Make 'uaddr' parameter optional for KVM_SEV_SNP_LAUNCH_UPDATE
I also did some minor updates (prefixed with a "[squash]" tag) to advertise
the KVM_SET_MEMORY_ATTRIBUTES2_PRESERVED flag so it can be used by
userspace for SNP/TDX in the kvm_gmem_populate() path as agreed upon
during PUCK.
The branch is here, with the patches moved to where I think they
should remain (or be squashed in for the [squash] ones):
https://github.com/AMDESE/linux/commits/guest_memfd-inplace-conversion-v4-snp2/
I've also updated the QEMU patches to use the agreed-upon API flow and
pushed them here:
https://github.com/AMDESE/qemu/commits/snp-inplace-for-v4-wip2/
To start an SNP guest with in-place conversion:
qemu-system-x86 \
-machine q35,confidential-guest-support=sev0,memory-backend=ram1 \
-object sev-snp-guest,id=sev0,...,convert-in-place=true \
-object memory-backend-memfd,id=ram1,size=16G,share=true,reserve=false
To start an normal non-CoCo guest backed by guest_memfd with shared memory:
qemu-system-x86 \
-machine q35,confidential-guest-support=sev0,memory-backend=ram1 \
-object memory-backend-memfd,id=ram1,size=16G,share=true,reserve=false
Thanks,

Shouldn't this refactoring be its own separate patch, similar to 4/5?
That would probably clean up this diff a bit.

And the same here, so one patch for interposing __queued_read_unlock()
and another for interposing __queued_write_unlock().

And is it possible to have one patch for qspinlock and another for qrwlock?
It *looks* like it should be.

Looks like this should be moved into tlat_var_reset().

How is the getopt_long table not the "actual implementation"?
Wouldn't it make more sense to fix the one place in the documentation
that says --dump-tasks to match what the current behavior is?
...except that apparently timerlat top does use --dump-tasks[1], so
maybe we want to make that consistent, but the changelog should be clear
that this is an interface change for timerlat hist.
We should also probably be making sure we have test coverage for both
hist and top, which would have caught this, rather than picking one or
the other for most tests.
-Crystal
[1] Oddly, timerlat_top.c is missing --dump-tasks from msg_start[],
which is the one place that timerlat_hist.c has the plural --dump-tasks.

Hello Sahil,
Thanks for your patches. I have a few questions. so this is not really a
technical review at the moment just some main items.

Why emulate l.adrp? We don't really use this yet in any OpenRISC code. This
instruction is meant to be used to help -fpic code, see:

Why remove the OPENRISC_ namespace from thse definitions?
Other architectures like arm64, riscv have namespaces on these similar
definitions.

I don't see why we need to name this six_bit as such. OpenRISC
instructions have either fir most significant 6-bits or 11-bits
as opcodes but we still use the first 6-bits to drive the logic.

This is for handling CPU's that do not have delay slots. We didn't do this
before, why are you doing it now? Should we mention this in the git commit
message?
Also, since this is a static configuration for the CPU should we use static keys
for this?

This function is not used, what will it be used for? Could you mention it in the
commit message? Also could you document it?

Since you are using this for more than just instruction simulation now, maybe
its good to document what it does. For example when we use it below we surround
it with the in_delay_slot check.

Naming this variable jmp is a bit misleading. Maybe something like
link_displacement, link_offset or fallthrough?

* [PATCH] tracefs: Removed unused 'ret' variable in eventfs_iterate()
From: Steven Rostedt @ 2026-04-14 15:03 UTC (permalink / raw)
To: LKML, Linux trace kernel; +Cc: Masami Hiramatsu, Mathieu Desnoyers
From: Steven Rostedt <rostedt@goodmis.org>
Moving to guard() usage removed the need of using the 'ret' variable but
it wasn't removed. As it was set to zero, the compiler in use didn't warn
(although some compilers do).
Fixes: 4d9b262031f ("eventfs: Simplify code using guard()s")
Reported-by: kernel test robot <lkp@intel.com>

I'm unclear about what is meant by the notifiers being moved back and
forth. The links point to patches that converted ftrace+klp from using
module notifiers to explicit callbacks due to ordering issues, but this
switch occurred only once. Have there been other attempts to use
notifiers again?

Nit: Avoid wrapping URLs, as it breaks autolinking and makes the links
harder to copy.
Better links would be:
[1] https://lore.kernel.org/all/1455661953-15838-1-git-send-email-jeyu@redhat.com/
[2] https://lore.kernel.org/all/1458176139-17455-1-git-send-email-jeyu@redhat.com/
The first link is the final version of what landed as commit
7dcd182bec27 ("ftrace/module: remove ftrace module notifier"). The
second is commit 7e545d6eca20 ("livepatch/module: remove livepatch
module notifier").

I don't see a reason to add a new module state. Why is it necessary and
how does it fit with the existing states?

I suggest being explicit about how the notifiers are ordered. For
example:
enum module_notifier_prio {
MODULE_NOTIFIER_PRIO_NORMAL, /* Normal priority, coming last, going first. */
MODULE_NOTIFIER_PRIO_LIVEPATCH,
MODULE_NOTIFIER_PRIO_FTRACE, /* High priority, coming first, going late. */
};

klp_module_coming() and klp_module_going() are now used only in
kernel/livepatch/core.c where they are also defined. This means the
functions can be static and their declarations removed from
include/linux/livepatch.h.
Nit: The MODULE_STATE_LIVE and default cases in the switch can be
removed.

The patch unexpectedly leaves a call to ftrace_free_mem() in

I believe val_down should be MODULE_STATE_GOING to reverse the
operation. Why is the new state MODULE_STATE_FORMED needed here?

My understanding is that all notifier chains for MODULE_STATE_GOING
should be reversed.

The patch removes the klp_module_going() cleanup call in load_module().
Similarly, the ftrace_release_mod() call under the ddebug_cleanup label
should be removed and appropriately replaced with a cleanup via
a notifier.

ftrace_module_init(), ftrace_module_enable(), ftrace_free_mem() and
ftrace_release_mod() should be newly used only in kernel/trace/ftrace.c
where they are also defined. The functions can then be made static and
removed from include/linux/ftrace.h.
Nit: The default case in the switch can be removed.

Nit: This can be simply "return NOTIFY_OK;".

* [PATCH v1] tools/rtla: Fix --dump-task option name to --dump-tasks
From: Costa Shulyupin @ 2026-04-14 14:06 UTC (permalink / raw)
To: Steven Rostedt, Tomas Glozar, Costa Shulyupin, Crystal Wood,
Wander Lairson Costa, Ivan Pravdin, linux-trace-kernel,
linux-kernel
The option was inconsistently named --dump-task in the usage
string and getopt_long table while the actual implementation
uses --dump-tasks. Fix both occurrences to match.

I believe it would be more productive to first answer the question in my
previous email and give others time to comment on the noted issue and
discuss a possible solution. The previous patch hasn't been accepted
yet, so sending a new patch on top of it just hours after my comment
seems unusual.
The patch contains some unrelated changes, such as renaming last_index
to next_index in find_next(). I suspect it was generated with the help
of AI but it isn't attributed as such. Please check
Documentation/process/coding-assistants.rst.
The implementation splits the trace_bprintk_fmt_list into two lists.
While this looks sensible, it creates nearly duplicate code for handling
the two lists, for example, hold_module_trace_format() and
hold_module_trace_format(), or lookup_mod_format_ptr() and
lookup_mod_tracepoint_ptr(). An alternative would be to keep one list
and have a 'struct module *mod' member to differentiate between the
strings. 'mod == NULL' for printk fmts and 'mod != NULL' for tracepoint
strings.
I also considered whether kernel/trace/trace_printk.c could avoid
tracking tracepoint strings altogether and instead have
find_next_mod_entry() directly traverse the modules list and
module::tracepoint_strings_start. However, this would require taking
both btrace_mutex and the RCU lock, and I believe it would be more
complex.
Since the tracepoint strings are now tracked only for the duration of
a module's lifetime, kernel/trace/trace_printk.c doesn't need to copy
the strings and can reference directly the original module data.
Alternatively, the original strings could be placed in an .init section
so that once trace_printk.c copies them and the module is initialized,
they get dropped.

* [PATCH v6 5/5] tracing/fprobe: Fix to unregister ftrace_ops if it is empty on module unloading
From: Masami Hiramatsu (Google) @ 2026-04-14 9:15 UTC (permalink / raw)
To: Steven Rostedt, Masami Hiramatsu
Cc: Menglong Dong, Mathieu Desnoyers, jiang.biao, linux-kernel,
linux-trace-kernel
In-Reply-To: <177615807787.1165997.921227352050738693.stgit@mhiramat.tok.corp.google.com>
From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
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

* [PATCH v6 4/5] tracing/fprobe: Check the same type fprobe on table as the unregistered one
From: Masami Hiramatsu (Google) @ 2026-04-14 9:15 UTC (permalink / raw)

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
Commit 2c67dc457bc6 ("tracing: fprobe: optimization for entry only case")
introduced a different ftrace_ops for entry-only fprobes.
However, when unregistering an fprobe, the kernel only checks if another
fprobe exists at the same address, without checking which type of fprobe
it is.
If different fprobes are registered at the same address, the same address
will be registered in both fgraph_ops and ftrace_ops, but only one of
them will be deleted when unregistering. (the one removed first will not
be deleted from the ops).
This results in junk entries remaining in either fgraph_ops or ftrace_ops.
For example:
=======
cd /sys/kernel/tracing
# 'Add entry and exit events on the same place'
echo 'f:event1 vfs_read' >> dynamic_events
echo 'f:event2 vfs_read%return' >> dynamic_events
# 'Enable both of them'
echo 1 > events/fprobes/enable
cat enabled_functions
vfs_read (2) ->arch_ftrace_ops_list_func+0x0/0x210
# 'Disable and remove exit event'
echo 0 > events/fprobes/event2/enable
echo -:event2 >> dynamic_events
# 'Disable and remove all events'
echo 0 > events/fprobes/enable
echo > dynamic_events
# 'Add another event'
echo 'f:event3 vfs_open%return' > dynamic_events
cat dynamic_events
f:fprobes/event3 vfs_open%return
echo 1 > events/fprobes/enable
cat enabled_functions
vfs_open (1) tramp: 0xffffffffa0001000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 subops: {ent:fprobe_fgraph_entry+0x0/0x620 ret:fprobe_return+0x0/0x150}
vfs_read (1) tramp: 0xffffffffa0001000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 subops: {ent:fprobe_fgraph_entry+0x0/0x620 ret:fprobe_return+0x0/0x150}
=======
As you can see, an entry for the vfs_read remains.
To fix this issue, when unregistering, the kernel should also check if
there is the same type of fprobes still exist at the same address, and
if not, delete its entry from either fgraph_ops or ftrace_ops.

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
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.

* [PATCH v6 2/5] tracing/fprobe: Remove fprobe from hash in failure path

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
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.

Changes in v6:
- Wait for an RCU grace period before returning error in
unregister_fprobe_nolock().
Changes in v5:
- When rolling back an fprobe that failed to register, the
fprobe_hash_node are forcibly removed and warn if failure.
Changes in v4:
- Remove short-cut case because we always need to upadte ftrace_ops.
- Use guard(mutex) in register_fprobe_ips() to unlock it correctly.
- Remove redundant !ret check in register_fprobe_ips().
- Do not set hlist_array->size in failure case, instead,
hlist_array->array[i].fp is set only when insertion is succeeded.
Changes in v3:
- Newly added.

* [PATCH v6 1/5] tracing/fprobe: Reject registration of a registered fprobe before init

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
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.

* [PATCH v6 0/5] tracing/fprobe: Fix fprobe_ip_table related bugs
From: Masami Hiramatsu (Google) @ 2026-04-14 9:14 UTC (permalink / raw)
To: Steven Rostedt, Masami Hiramatsu

Hi,
Here is the 6th version of fprobe bugfix series.
The previous version is here.
https://lore.kernel.org/all/177606956628.929411.17392736689322577701.stgit@devnote2/
In this version, I added yet another bugfixes for rejecting registered
fprobe correctly [1/5], and unregistering ftrace_ops if it is empty on
module unloading [5/5]. Also, add RCU synchronization for failure path
[2/5] and retry rhashtable walking outside of rhltable_walk_enter/exit
[3/5].
The [5/5] is to handle the module unloading problem I reported
previously [1]. This was handled solely within fprobe to avoid
impacting the live patch.
[1] https://lore.kernel.org/all/20260408110237.08d982fab08356bc8d48af45@kernel.org/
Thank you!
Masami Hiramatsu (Google) (5):
tracing/fprobe: Reject registration of a registered fprobe before init
tracing/fprobe: Remove fprobe from hash in failure path
tracing/fprobe: Avoid kcalloc() in rcu_read_lock section
tracing/fprobe: Check the same type fprobe on table as the unregistered one

IMHO, when the number of VMAs in the i_mmap is very large, only optimise the rwsem
lock does not help too much for our NUMA case.
In our NUMA server, the remote access could be the major issue.

Yes, this patch set only focus on the NUMA case.
The one-node case should use the original i_mmap.
Maybe I can add a new config, CONFIG_SPILT_I_MMAP. The config is disabled
by default, and enabled when the NUMA node is not one.

The traversal may need to hold many locks.

This patch set is to reduce the remote access latency for insert/remove VMA
in NUMA.

I ever tried.
But there are two disadvantages:
1.) The traversal may need to hold many locks which makes the
code very horrible.
2.) Even we split the locks. Each lock protects a tree, when the tree becomes
big enough, the VMA insert/remove will also become slow in NUMA.
The reason is that the tree has VMAs in different NUMA nodes.

A patch should do one thing at a time. This patch appears to be doing
two things: fixing the bound strings, returning errors instead of NULL.
Please split this up into two patches. One that changes the return
values from NULL to ERR_PTR() and the other to use seq_buf.

Note, the above is equivalent to:
if (event_var)
return event_var;
And since it is a separate issue than the bounding of the string, it
