46f5bef8ec thermal: core: Drop the .set_trip_hyst() thermal zone operation
None of the users of the thermal core provides a .set_trip_hyst()
thermal zone operation, so drop that callback from struct
thermal_zone_device_ops and update trip_point_hyst_store()
accordingly.

No functional impact.

5340f76472 thermal: core: Add flags to struct thermal_trip
In order to allow thermal zone creators to specify the writability of
trip point temperature and hysteresis on a per-trip basis, add a flags
field to struct thermal_trip and define flags to represent the desired
trip properties.

Also make thermal_zone_device_register_with_trips() set the
THERMAL_TRIP_FLAG_RW_TEMP flag for all trips covered by the writable
trips mask passed to it and modify the thermal sysfs code to look at
the trip flags instead of using the writable trips mask directly or
checking the presence of the .set_trip_hyst() zone callback.

Additionally, make trip_point_temp_store() and trip_point_hyst_store()
fail with an error code if the trip passed to one of them has
THERMAL_TRIP_FLAG_RW_TEMP or THERMAL_TRIP_FLAG_RW_HYST,
respectively, clear in its flags.

No intentional functional impact.

da1983355c thermal: core: Move initial num_trips assignment before memcpy()
When booting a CONFIG_FORTIFY_SOURCE=y kernel compiled with a toolchain
that supports __counted_by() (such as clang-18 and newer), there is a
panic on boot:

  [    2.913770] memcpy: detected buffer overflow: 72 byte write of buffer size 0
  [    2.920834] WARNING: CPU: 2 PID: 1 at lib/string_helpers.c:1027 __fortify_report+0x5c/0x74
  ...
  [    3.039208] Call trace:
  [    3.041643]  __fortify_report+0x5c/0x74
  [    3.045469]  __fortify_panic+0x18/0x20
  [    3.049209]  thermal_zone_device_register_with_trips+0x4c8/0x4f8

This panic occurs because trips is counted by num_trips but num_trips is
assigned after the call to memcpy(), so the fortify checks think the
buffer size is zero because tz was allocated with kzalloc().

Move the num_trips assignment before the memcpy() to resolve the panic
and ensure that the fortify checks work properly.

a85739c8c6 thermal: Get rid of CONFIG_THERMAL_WRITABLE_TRIPS
The only difference made by CONFIG_THERMAL_WRITABLE_TRIPS is whether or
not the writable trips mask passed during thermal zone registration
will take any effect, but whoever passes a non-zero writable trips mask
to thermal_zone_device_register_with_trips() can be forgiven thinking
that it will always work.

Moreover, some thermal drivers expect user space to set trip temperature
values, so they select CONFIG_THERMAL_WRITABLE_TRIPS, possibly overriding
a manual choice to unset it and going against the design purportedly
allowing system integrators to decide on the writability of trip points
for the given kernel build.  It is also set in one platform's defconfig.

Forthermore, CONFIG_THERMAL_WRITABLE_TRIPS only affects trip temperature,
because trip hysteresis is writable as long as the thermal zone provides
a callback to update it, regardless of the CONFIG_THERMAL_WRITABLE_TRIPS
value.

The above means that the symbol in question is used inconsistently and
its purpose is at least moot, so remove it and always take the writable
trip mask passed to thermal_zone_device_register_with_trips() into
account.

62dd17846d thermal: intel: Adjust ops handling during thermal zone registration
Because thermal zone operations are now stored directly in struct
thermal_zone_device, thermal zone creators can discard the operations
structure after the zone registration is complete, or it can be made
read-only.

Accordingly, make int340x_thermal_zone_add() use a local variable to
represent thermal zone operations, so it is freed automatically upon the
function exit, and make the other Intel thermal drivers use const zone
operations structures.

698a1eb1f7 thermal: core: Store zone ops in struct thermal_zone_device
The current code requires thermal zone creators to pass pointers to
writable ops structures to thermal_zone_device_register_with_trips()
which needs to modify the target struct thermal_zone_device_ops object
if the "critical" operation in it is NULL.

Moreover, the callers of thermal_zone_device_register_with_trips() are
required to hold on to the struct thermal_zone_device_ops object passed
to it until the given thermal zone is unregistered.

Both of these requirements are quite inconvenient, so modify struct
thermal_zone_device to contain struct thermal_zone_device_ops as field and
make thermal_zone_device_register_with_trips() copy the contents of the
struct thermal_zone_device_ops passed to it via a pointer (which can be
const now) to that field.

Also adjust the code using thermal zone ops accordingly and modify
thermal_of_zone_register() to use a local ops variable during
thermal zone registration so ops do not need to be freed in
thermal_of_zone_unregister() any more.

Because the thermal core creates and uses its own copy of the trips

Accordingly, modify Intel thermal drivers to discard the trips tables

9b0a627586 thermal: core: Store zone trips table in struct thermal_zone_device
The current code expects thermal zone creators to pass a pointer to a
writable trips table to thermal_zone_device_register_with_trips() and
that trips table is then used by the thermal core going forward.

Consequently, the callers of thermal_zone_device_register_with_trips()
are required to hold on to the trips table passed to it until the given
thermal zone is unregistered, at which point the trips table can be
freed, but at the same time they are not expected to access that table
directly.  This is both error prone and confusing.

To address it, turn the trips table pointer in struct thermal_zone_device
into a flex array (counted by its num_trips field), allocate it during
thermal zone device allocation and copy the contents of the trips table
supplied by the zone creator (which can be const now) into it, which
will allow the callers of thermal_zone_device_register_with_trips() to
drop their trip tables right after the zone registration.

This requires the imx thermal driver to be adjusted to store the new
temperature in its internal trips table in imx_set_trip_temp(), because
it will be separate from the core's trips table now and it has to be
explicitly kept in sync with the latter.

0fac6893ff thermal: gov_power_allocator: Avoid overwriting PID coefficients from setup time
When the PID coefficients k_* are set via sysfs before the IPA
algorithm is triggered then the coefficients would be overwritten after
IPA throttle() is called. The old configuration values might be
different than the new values estimated by the IPA internal algorithm.

There might be a time delay when this overwriting happens. It
depends on the thermal zone temperature value. The temperature value
needs to cross the first trip point value then IPA algorithms start
operating. Although, the PID coefficients setup time should not be
affected or linked to any later operating phase and values must not be
overwritten.

This patch initializes params->sustainable_power when the governor
binds to thermal zone to avoid overwriting k_*. The basic function won't
be affected, as the k_* still can be estimated if the sustainable_power
is modified.

Pull firewire fix from Takashi Sakamoto:
 "A change to accelerate the device detection step in some cases.

  In the self-identification step after bus-reset, all nodes in the same
  bus broadcast selfID packet including the value of gap count. The
  value is related to the cable hops between nodes, and used to
  calculate the subaction gap and the arbitration reset gap.

  When each node has the different value of the gap count, the
  asynchronous communication between them is unreliable, since an
  asynchronous transaction could be interrupted by another asynchronous
  transaction before completion. The gap count inconsistency can be
  resolved by several ways; e.g. the transfer of PHY configuration
  packet and generation of bus-reset.

  The current implementation of firewire stack can correctly detect the
  gap count inconsistency, however the recovery action from the
  inconsistency tends to be delayed after reading configuration ROM of
  root node. This results in the long time to probe devices in some
  combinations of hardware.

  Here the stack is changed to schedule the action as soon as possible"

4356e9f841 work around gcc bugs with 'asm goto' with outputs
We've had issues with gcc and 'asm goto' before, and we created a
'asm_volatile_goto()' macro for that in the past: see commits
3f0116c323 ("compiler/gcc4: Add quirk for 'asm goto' miscompilation
bug") and a9f180345f ("compiler/gcc4: Make quirk for
asm_volatile_goto() unconditional").

Then, much later, we ended up removing the workaround in commit
43c249ea0b ("compiler-gcc.h: remove ancient workaround for gcc PR
58670") because we no longer supported building the kernel with the
affected gcc versions, but we left the macro uses around.

Now, Sean Christopherson reports a new version of a very similar
problem, which is fixed by re-applying that ancient workaround.  But the
problem in question is limited to only the 'asm goto with outputs'
cases, so instead of re-introducing the old workaround as-is, let's
rename and limit the workaround to just that much less common case.

It looks like there are at least two separate issues that all hit in
this area:

 (a) some versions of gcc don't mark the asm goto as 'volatile' when it
     has outputs:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619
        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420

     which is easy to work around by just adding the 'volatile' by hand.

 (b) Internal compiler errors:

        https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422

     which are worked around by adding the extra empty 'asm' as a
     barrier, as in the original workaround.

but the problem Sean sees may be a third thing since it involves bad
code generation (not an ICE) even with the manually added 'volatile'.

but the same old workaround works for this case, even if this feels a
bit like voodoo programming and may only be hiding the issue.

a5cc98eba2 smb3: clarify mount warning
When a user tries to use the "sec=krb5p" mount parameter to encrypt
data on connection to a server (when authenticating with Kerberos), we
indicate that it is not supported, but do not note the equivalent
recommended mount parameter ("sec=krb5,seal") which turns on encryption
for that mount (and uses Kerberos for auth).  Update the warning message.

a39c757bf0 cifs: handle cases where multiple sessions share connection
Based on our implementation of multichannel, it is entirely
possible that a server struct may not be found in any channel
of an SMB session.

In such cases, we should be prepared to move on and search for
the server struct in the next session.

c6e02eefd6 cifs: change tcon status when need_reconnect is set on it
When a tcon is marked for need_reconnect, the intention
is to have it reconnected.

This change adjusts tcon->status in cifs_tree_connect
when need_reconnect is set. Also, this change has a minor
correction in resetting need_reconnect on success. It makes
sure that it is done with tc_lock held.

Pull tracing fixes from Steven Rostedt:

 - Fix broken direct trampolines being called when another callback is
   attached the same function.

   ARM 64 does not support FTRACE_WITH_REGS, and when it added direct
   trampoline calls from ftrace, it removed the "WITH_REGS" flag from
   the ftrace_ops for direct trampolines. This broke x86 as x86 requires
   direct trampolines to have WITH_REGS.

   This wasn't noticed because direct trampolines work as long as the
   function it is attached to is not shared with other callbacks (like
   the function tracer). When there are other callbacks, a helper
   trampoline is called, to call all the non direct callbacks and when
   it returns, the direct trampoline is called.

   For x86, the direct trampoline sets a flag in the regs field to tell
   the x86 specific code to call the direct trampoline. But this only
   works if the ftrace_ops had WITH_REGS set. ARM does things
   differently that does not require this. For now, set WITH_REGS if the
   arch supports WITH_REGS (which ARM does not), and this makes it work
   for both ARM64 and x86.

 - Fix wasted memory in the saved_cmdlines logic.

   The saved_cmdlines is a cache that maps PIDs to COMMs that tracing
   can use. Most trace events only save the PID in the event. The
   saved_cmdlines file lists PIDs to COMMs so that the tracing tools can
   show an actual name and not just a PID for each event. There's an
   array of PIDs that map to a small set of saved COMM strings. The
   array is set to PID_MAX_DEFAULT which is usually set to 32768. When a
   PID comes in, it will add itself to this array along with the index
   into the COMM array (note if the system allows more than
   PID_MAX_DEFAULT, this cache is similar to cache lines as an update of
   a PID that has the same PID_MAX_DEFAULT bits set will flush out
   another task with the same matching bits set).

   A while ago, the size of this cache was changed to be dynamic and the
   array was moved into a structure and created with kmalloc(). But this
   new structure had the size of 131104 bytes, or 0x20020 in hex. As
   kmalloc allocates in powers of two, it was actually allocating
   0x40000 bytes (262144) leaving 131040 bytes of wasted memory. The
   last element of this structure was a pointer to the COMM string array
   which defaulted to just saving 128 COMMs.

   By changing the last field of this structure to a variable length
   string, and just having it round up to fill the allocated memory, the
   default size of the saved COMM cache is now 8190. This not only uses
   the wasted space, but actually saves space by removing the extra
   allocation for the COMM names.

44dc5c41b5 tracing: Fix wasted memory in saved_cmdlines logic
While looking at improving the saved_cmdlines cache I found a huge amount
of wasted memory that should be used for the cmdlines.

The tracing data saves pids during the trace. At sched switch, if a trace
occurred, it will save the comm of the task that did the trace. This is
saved in a "cache" that maps pids to comms and exposed to user space via
the /sys/kernel/tracing/saved_cmdlines file. Currently it only caches by
default 128 comms.

The structure that uses this creates an array to store the pids using
PID_MAX_DEFAULT (which is usually set to 32768). This causes the structure
to be of the size of 131104 bytes on 64 bit machines.

In hex: 131104 = 0x20020, and since the kernel allocates generic memory in
powers of two, the kernel would allocate 0x40000 or 262144 bytes to store
this structure. That leaves 131040 bytes of wasted space.

Worse, the structure points to an allocated array to store the comm names,
which is 16 bytes times the amount of names to save (currently 128), which
is 2048 bytes. Instead of allocating a separate array, make the structure
end with a variable length string and use the extra space for that.

This is similar to a recommendation that Linus had made about eventfs_inode names:

  https://lore.kernel.org/all/20240130190355.11486-5-torvalds@linux-foundation.org/

Instead of allocating a separate string array to hold the saved comms,
have the structure end with: char saved_cmdlines[]; and round up to the
next power of two over sizeof(struct saved_cmdline_buffers) + num_cmdlines * TASK_COMM_LEN
It will use this extra space for the saved_cmdline portion.

Now, instead of saving only 128 comms by default, by using this wasted
space at the end of the structure it can save over 8000 comms and even
saves space by removing the need for allocating the other array.

a8b9cf62ad ftrace: Fix DIRECT_CALLS to use SAVE_REGS by default
The commit 60c8971899 ("ftrace: Make DIRECT_CALLS work WITH_ARGS
and !WITH_REGS") changed DIRECT_CALLS to use SAVE_ARGS when there
are multiple ftrace_ops at the same function, but since the x86 only
support to jump to direct_call from ftrace_regs_caller, when we set
the function tracer on the same target function on x86, ftrace-direct
does not work as below (this actually works on arm64.)

At first, insmod ftrace-direct.ko to put a direct_call on
'wake_up_process()'.

 # insmod kernel/samples/ftrace/ftrace-direct.ko
 # less trace
...
          <idle>-0       [006] ..s1.   564.686958: my_direct_func: waking up rcu_preempt-17
          <idle>-0       [007] ..s1.   564.687836: my_direct_func: waking up kcompactd0-63
          <idle>-0       [006] ..s1.   564.690926: my_direct_func: waking up rcu_preempt-17
          <idle>-0       [006] ..s1.   564.696872: my_direct_func: waking up rcu_preempt-17
          <idle>-0       [007] ..s1.   565.191982: my_direct_func: waking up kcompactd0-63

Setup a function filter to the 'wake_up_process' too, and enable it.

 # cd /sys/kernel/tracing/
 # echo wake_up_process > set_ftrace_filter
 # echo function > current_tracer
 # less trace
...
          <idle>-0       [006] ..s3.   686.180972: wake_up_process <-call_timer_fn
          <idle>-0       [006] ..s3.   686.186919: wake_up_process <-call_timer_fn
          <idle>-0       [002] ..s3.   686.264049: wake_up_process <-call_timer_fn
          <idle>-0       [002] d.h6.   686.515216: wake_up_process <-kick_pool
          <idle>-0       [002] d.h6.   686.691386: wake_up_process <-kick_pool

Then, only function tracer is shown on x86.
But if you enable 'kprobe on ftrace' event (which uses SAVE_REGS flag)
on the same function, it is shown again.

 # echo 'p wake_up_process' >> dynamic_events
 # echo 1 > events/kprobes/p_wake_up_process_0/enable
 # echo > trace
 # less trace
...
          <idle>-0       [006] ..s2.  2710.345919: p_wake_up_process_0: (wake_up_process+0x4/0x20)
          <idle>-0       [006] ..s3.  2710.345923: wake_up_process <-call_timer_fn
          <idle>-0       [006] ..s1.  2710.345928: my_direct_func: waking up rcu_preempt-17
          <idle>-0       [006] ..s2.  2710.349931: p_wake_up_process_0: (wake_up_process+0x4/0x20)

          <idle>-0       [006] ..s1.  2710.349937: my_direct_func: waking up rcu_preempt-17

To fix this issue, use SAVE_REGS flag for multiple ftrace_ops flag of
direct_call by default.
