The MediaTek implementation of the sbsa_gwdt watchdog has a race
condition where a write to SBSA_GWDT_WRR is ignored if it occurs while
the hardware is processing a timeout refresh that asserts WS0.
Detect this based on the hardware implementer and adjust
wdd->min_hw_heartbeat_ms to avoid the race by forcing the keepalive ping
to be one second later.

During communication with Focusrite Scarlett Gen 2/3/4 USB audio
interfaces, -EPROTO is sometimes returned from scarlett2_usb_tx(),
snd_usb_ctl_msg() which can cause initialisation and control
operations to fail intermittently.
This patch adds up to 5 retries in scarlett2_usb(), with a delay
starting at 5ms and doubling each time. This follows the same approach
as the fix for usb_set_interface() in endpoint.c (commit f406005e162b
("ALSA: usb-audio: Add retry on -EPROTO from usb_set_interface()")),
which resolved similar -EPROTO issues during device initialisation,
and is the same approach as in fcp.c:fcp_usb().

Before commit df6d7277e552 ("i2c: core: Do not dereference fwnode in struct
device"), i2c_unregister_device() only called fwnode_handle_put() on
of_node-s in the form of calling of_node_put(client->dev.of_node).
But after this commit the i2c_client's fwnode now unconditionally gets
fwnode_handle_put() on it.
When the i2c_client has no primary (ACPI / OF) fwnode but it does have
a software fwnode, the software-node will be the primary node and
fwnode_handle_put() will put() it.
But for the software fwnode device_remove_software_node() will also put()
it leading to a double free:

Add support for the Texas Instruments INA228 Ultra-Precise
Power/Energy/Charge Monitor.
The INA228 is very similar to the INA238 but offers four bits of extra
precision in the temperature, voltage and current measurement fields.
It also supports energy and charge monitoring, the latter of which is
not supported through this patch.
While it seems in the datasheet that some constants such as LSB values
differ between the 228 and the 238, they differ only for those registers
where four bits of precision have been added and they differ by a factor
of 16 (VBUS, VSHUNT, DIETEMP, CURRENT).
Therefore, the INA238 constants are still applicable with regard
to the bit of the same significance.

SMB1 already supports querying reparse points and detecting types of
symlink, fifo, socket, block and char.
This change implements the missing part - ability to create a new reparse
points over SMB1. This includes everything which SMB2+ already supports:
- native SMB symlinks and sockets
- NFS style of special files (symlinks, fifos, sockets, char/block devs)
- WSL style of special files (symlinks, fifos, sockets, char/block devs)
Attaching a reparse point to an existing file or directory is done via
SMB1 SMB_COM_NT_TRANSACT/NT_TRANSACT_IOCTL/FSCTL_SET_REPARSE_POINT command
and implemented in a new cifs_create_reparse_inode() function.
This change introduce a new callback ->create_reparse_inode() which creates
a new reperse point file or directory and returns inode. For SMB1 it is
provided via that new cifs_create_reparse_inode() function.
Existing reparse.c code was only slightly updated to call new protocol
callback ->create_reparse_inode() instead of hardcoded SMB2+ function.
This make the whole reparse.c code to work with every SMB dialect.
The original callback ->create_reparse_symlink() is not needed anymore as
the implementation of new create_reparse_symlink() function is dialect
agnostic too. So the link.c code was updated to call that function directly
(and not via callback).

When not searching for child entries with msearch wildcard pattern then ask
server just for one output entry. There is no need to ask for more entries
as we are interested only for one search result, as we are doing query on

To query root path (without msearch wildcard) it is needed to
send pattern '\' instead of '' (empty string).
This allows to use CIFSFindFirst() to query information about root path
which is being used in followup changes.
This change fixes the stat() syscall called on the root path on the mount.
It is because stat() syscall uses the cifs_query_path_info() function and
it can fallback to the CIFSFindFirst() usage with msearch=false.

We now do a weighted selection of server interfaces when allocating
new channels. The weights are decided based on the speed advertised.
The fulfilled weight for an interface is a counter that is used to
track the interface selection. It should be reset back to zero once
all interfaces fulfilling their weight.
In cifs_chan_update_iface, this reset logic was missing. As a result
when the server interface list changes, the client may not be able
to find a new candidate for other channels after all interfaces have
been fulfilled.

After commit 5c70eb5c593d ("net: better track kernel sockets lifetime"),
kernel sockets now use net_passive reference counting. However, commit
95d2b9f693ff ("Revert "smb: client: fix TCP timers deadlock after rmmod"")
restored the manual socket refcount manipulation without adapting to this
new mechanism, causing a memory leak.
The issue can be reproduced by[1]:
1. Creating a network namespace
2. Mounting and Unmounting CIFS within the namespace
3. Deleting the namespace
Some memory leaks may appear after a period of time following step 3.

Root cause:
When creating kernel sockets, sk_alloc() calls net_passive_inc() for
sockets with sk_net_refcnt=0. The CIFS code manually converts kernel
sockets to user sockets by setting sk_net_refcnt=1, but doesn't call
the corresponding net_passive_dec(). This creates an imbalance in the
net_passive counter, which prevents the network namespace from being
destroyed when its last user reference is dropped. As a result, the
entire namespace and all its associated resources remain allocated.
Timeline of patches leading to this issue:
- commit ef7134c7fc48 ("smb: client: Fix use-after-free of network
namespace.") in v6.12 fixed the original netns UAF by manually
managing socket refcounts
- commit e9f2517a3e18 ("smb: client: fix TCP timers deadlock after
rmmod") in v6.13 attempted to use kernel sockets but introduced
TCP timer issues
- commit 5c70eb5c593d ("net: better track kernel sockets lifetime")
in v6.14-rc5 introduced the net_passive mechanism with
sk_net_refcnt_upgrade() for proper socket conversion
- commit 95d2b9f693ff ("Revert "smb: client: fix TCP timers deadlock
after rmmod"") in v6.15-rc3 reverted to manual refcount management
without adapting to the new net_passive changes
Fix this by using sk_net_refcnt_upgrade() which properly handles the
net_passive counter when converting kernel sockets to user sockets.

During the bounds refinement, we improve the precision of various ranges
by looking at other ranges. Among others, we improve the following in
this order (other things happen between 1 and 2):
1. Improve u32 from s32 in __reg32_deduce_bounds.
2. Improve s/u64 from u32 in __reg_deduce_mixed_bounds.
3. Improve s/u64 from s32 in __reg_deduce_mixed_bounds.
In particular, if the s32 range forms a valid u32 range, we will use it
to improve the u32 range in __reg32_deduce_bounds. In
__reg_deduce_mixed_bounds, under the same condition, we will use the s32
range to improve the s/u64 ranges.
If at (1) we were able to learn from s32 to improve u32, we'll then be
able to use that in (2) to improve s/u64. Hence, as (3) happens under
the same precondition as (1), it won't improve s/u64 ranges further than
(1)+(2) did. Thus, we can get rid of (3).
In addition to the extensive suite of selftests for bounds refinement,
this patch was also tested with the Agni formal verification tool [1].
Additionally, Eduard mentioned:
The argument appears to be as follows:
Under precondition `(u32)reg->s32_min <= (u32)reg->s32_max`
__reg32_deduce_bounds produces:
reg->u32_min = max_t(u32, reg->s32_min, reg->u32_min);
reg->u32_max = min_t(u32, reg->s32_max, reg->u32_max);
And then first part of __reg_deduce_mixed_bounds assigns:
a. reg->umin umax= (reg->umin & ~0xffffffffULL) | max_t(u32, reg->s32_min, reg->u32_min);
b. reg->umax umin= (reg->umax & ~0xffffffffULL) | min_t(u32, reg->s32_max, reg->u32_max);
And then second part of __reg_deduce_mixed_bounds assigns:
c. reg->umin umax= (reg->umin & ~0xffffffffULL) | (u32)reg->s32_min;
d. reg->umax umin= (reg->umax & ~0xffffffffULL) | (u32)reg->s32_max;
But assignment (c) is a noop because:
max_t(u32, reg->s32_min, reg->u32_min) >= (u32)reg->s32_min
Hence RHS(a) >= RHS(c) and umin= does nothing.
Also assignment (d) is a noop because:
min_t(u32, reg->s32_max, reg->u32_max) <= (u32)reg->s32_max
Hence RHS(b) <= RHS(d) and umin= does nothing.
Plus the same reasoning for the part dealing with reg->s{min,max}_value:
e. reg->smin_value smax= (reg->smin_value & ~0xffffffffULL) | max_t(u32, reg->s32_min_value, reg->u32_min_value);
f. reg->smax_value smin= (reg->smax_value & ~0xffffffffULL) | min_t(u32, reg->s32_max_value, reg->u32_max_value);
vs
g. reg->smin_value smax= (reg->smin_value & ~0xffffffffULL) | (u32)reg->s32_min_value;
h. reg->smax_value smin= (reg->smax_value & ~0xffffffffULL) | (u32)reg->s32_max_value;
RHS(e) >= RHS(g) and RHS(f) <= RHS(h), hence smax=,smin= do nothing.
This appears to be correct.
Also, Shung-Hsi:
Beside going through the reasoning, I also played with CBMC a bit to
double check that as far as a single run of __reg_deduce_bounds() is
concerned (and that the register state matches certain handwavy
expectations), the change indeed still preserve the original behavior.

Pull timer fix from Thomas Gleixner:
"A single fix for the PTP systemcounter mechanism:
The rework of this mechanism added a 'use_nsec' member to struct
system_counterval. get_device_system_crosststamp() instantiates that
struct on the stack and hands a pointer to the driver callback.
Only the drivers which set use_nsec to true, initialize that field,
but all others ignore it. As get_device_system_crosststamp() does not
initialize the struct, the use_nsec field contains random stack
content in those cases. That causes a miscalulation usually resulting
in a failing range check in the best case.
Initialize the structure before handing it to the drivers to cure
that"

The `adf_ring_next()` function in the QAT debug transport interface
fails to correctly update the position index when reaching the end of
the ring elements. This triggers the following kernel warning when
reading ring files, such as
/sys/kernel/debug/qat_c6xx_<D:B:D:F>/transport/bank_00/ring_00:
[27725.022965] seq_file: buggy .next function adf_ring_next [intel_qat] did not update position index
Ensure that the `*pos` index is incremented before returning NULL when
after the last element in the ring is found, satisfying the seq_file API
requirements and preventing the warning.

QAT devices perform an additional integrity check during compression by
decompressing the output. Starting from QAT GEN4, this verification is
done in-line by the hardware. However, on GEN2 devices, the hardware
reads back the compressed output from the destination buffer and performs
a decompression operation using it as the source.
In the current QAT driver, destination buffers are always marked as
write-only. This is incorrect for QAT GEN2 compression, where the buffer
is also read during verification. Since commit 6f5dc7658094
("iommu/vt-d: Restore WO permissions on second-level paging entries"),
merged in v6.16-rc1, write-only permissions are strictly enforced, leading
to DMAR errors when using QAT GEN2 devices for compression, if VT-d is
enabled.
Mark the destination buffers as DMA_BIDIRECTIONAL. This ensures
compatibility with GEN2 devices, even though it is not required for
QAT GEN4 and later.

A few drivers that use the legacy GPIOLIB interfaces can be enabled
even when GPIOLIB is disabled entirely. With my previous patch this
now causes build failures like:
drivers/nfc/s3fwrn5/uart.c: In function 's3fwrn82_uart_parse_dt':
drivers/nfc/s3fwrn5/uart.c:100:14: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration]
These did not show up in my randconfig tests because randconfig almost
always has GPIOLIB selected by some other driver, and I did most
of the testing with follow-up patches that address the failures
properly.
Move the symbol outside of the 'if CONFIG_GPIOLIB' block for the moment
to avoid the build failures. It can be moved back and turned off by
default once all the driver specific changes are merged.

Remove the hard coded encodings from parse-events. This has the
consequence that software events are matched using the sysfs/json
priority, will be case insensitive and will be wildcarded across PMUs.
As there were software and hardware types in the parsing code, the
removal means software vs hardware logic can be removed and hardware
assumed.
Now the perf json provides detailed descriptions of software events,
remove the previous listing support that didn't contain event
descriptions. When globbing is required for the "sw" option in perf
list, use string PMU globbing as was done previously for the tool PMU.
The output of `perf list sw` command changed like this.
Before:
List of pre-defined events (to be used in -e or -M):
alignment-faults [Software event]
bpf-output [Software event]
cgroup-switches [Software event]
context-switches OR cs [Software event]
cpu-clock [Software event]
cpu-migrations OR migrations [Software event]
dummy [Software event]
emulation-faults [Software event]
major-faults [Software event]

Add json for software events so that in perf list the events can have
a description. Common json exists for the tool PMU but it has no
sysfs equivalent. Modify the map_for_pmu code to return the common map
(rather than an architecture specific one) when a PMU with a common
name is being looked for, this allows the events to be found.
