LoongArch: Change 8 to 14 for LOONGARCH_MAX_{BRP,WRP}
commit f502ea618bf16d615d7dc6138c8988d3118fe750 upstream.
The maximum number of load/store watchpoints and fetch instruction
watchpoints is 14 each according to LoongArch Reference Manual, so
change 8 to 14 for the related code.

s390: Add '-std=gnu11' to decompressor and purgatory CFLAGS
commit 3b8b80e993766dc96d1a1c01c62f5d15fafc79b9 upstream.
GCC changed the default C standard dialect from gnu17 to gnu23,
which should not have impacted the kernel because it explicitly requests
the gnu11 standard in the main Makefile. However, there are certain
places in the s390 code that use their own CFLAGS without a '-std='
value, which break with this dialect change because of the kernel's own
definitions of bool, false, and true conflicting with the C23 reserved
keywords.
include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant
11 | false = 0,
| ^~~~~
include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards
include/linux/types.h:35:33: error: 'bool' cannot be defined via 'typedef'
35 | typedef _Bool bool;
| ^~~~
include/linux/types.h:35:33: note: 'bool' is a keyword with '-std=c23' onwards
Add '-std=gnu11' to the decompressor and purgatory CFLAGS to eliminate
these errors and make the C standard version of these areas match the
rest of the kernel.

btrfs: output the reason for open_ctree() failure
commit d0f038104fa37380e2a725e669508e43d0c503e9 upstream.
There is a recent ML report that mounting a large fs backed by hardware
RAID56 controller (with one device missing) took too much time, and
systemd seems to kill the mount attempt.
In that case, the only error message is:
BTRFS error (device sdj): open_ctree failed
There is no reason on why the failure happened, making it very hard to
understand the reason.
At least output the error number (in the particular case it should be
-EINTR) to provide some clue.

media: imx-jpeg: Fix potential error pointer dereference in detach_pm()
commit 1378ffec30367233152b7dbf4fa6a25ee98585d1 upstream.
The proble is on the first line:
if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i]))
If jpeg->pd_dev[i] is an error pointer, then passing it to
pm_runtime_suspended() will lead to an Oops. The other conditions
check for both error pointers and NULL, but it would be more clear to
use the IS_ERR_OR_NULL() check for that.

This happens because in v4l2_i2c_subdev_init(), the i2c_set_cliendata()
is called again and the data is overwritten to point to sd, instead of
priv. So, in remove(), the wrong pointer is passed to
v4l2_async_unregister_subdev(), leading to a crash.

...followed by more symptoms of corruption, with similar stacks:
refcount_t: underflow; use-after-free.
kernel BUG at lib/list_debug.c:62!
Kernel panic - not syncing: Oops - BUG: Fatal exception
This happens because pps_device_destruct() frees the pps_device with the
embedded cdev immediately after calling cdev_del(), but, as the comment
above cdev_del() notes, fops for previously opened cdevs are still
callable even after cdev_del() returns. I think this bug has always
been there: I can't explain why it suddenly started happening every time
I reboot this particular board.
In commit d953e0e837e6 ("pps: Fix a use-after free bug when
unregistering a source."), George Spelvin suggested removing the
embedded cdev. That seems like the simplest way to fix this, so I've
implemented his suggestion, using __register_chrdev() with pps_idr
becoming the source of truth for which minor corresponds to which
device.
But now that pps_idr defines userspace visibility instead of cdev_add(),
we need to be sure the pps->dev refcount can't reach zero while
userspace can still find it again. So, the idr_remove() call moves to
pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev.

remoteproc: core: Fix ida_free call while not allocated
commit 7378aeb664e5ebc396950b36a1f2dedf5aabec20 upstream.
In the rproc_alloc() function, on error, put_device(&rproc->dev) is
called, leading to the call of the rproc_type_release() function.
An error can occurs before ida_alloc is called.
In such case in rproc_type_release(), the condition (rproc->index >= 0) is
true as rproc->index has been initialized to 0.
ida_free() is called reporting a warning:

The root cause is the bad handling of disconnect() generated internally
by the MPTCP protocol in case of connect FASTOPEN errors.
Address the issue increasing the socket disconnect counter even on such
a case, to allow other threads waiting on the same socket lock to
properly error out.

mptcp: consolidate suboption status
commit c86b000782daba926c627d2fa00c3f60a75e7472 upstream.
MPTCP maintains the received sub-options status is the bitmask carrying
the received suboptions and in several bitfields carrying per suboption
additional info.
Zeroing the bitmask before parsing is not enough to ensure a consistent
status, and the MPTCP code has to additionally clear some bitfiled
depending on the actually parsed suboption.
The above schema is fragile, and syzbot managed to trigger a path where
a relevant bitfield is not cleared/initialized:

The current schema is too fragile; address the issue grouping all the
state-related data together and clearing the whole group instead of
just the bitmask. This also cleans-up the code a bit, as there is no
need to individually clear "random" bitfield in a couple of places
any more.

usb: typec: tcpci: Prevent Sink disconnection before vPpsShutdown in SPR PPS
commit 4d27afbf256028a1f54363367f30efc8854433c3 upstream.
The Source can drop its output voltage to the minimum of the requested
PPS APDO voltage range when it is in Current Limit Mode. If this voltage
falls within the range of vPpsShutdown, the Source initiates a Hard
Reset and discharges Vbus. However, currently the Sink may disconnect
before the voltage reaches vPpsShutdown, leading to unexpected behavior.
Prevent premature disconnection by setting the Sink's disconnect
threshold to the minimum vPpsShutdown value. Additionally, consider the
voltage drop due to IR drop when calculating the appropriate threshold.
This ensures a robust and reliable interaction between the Source and
Sink during SPR PPS Current Limit Mode operation.

usb: dwc3: core: Defer the probe until USB power supply ready
commit 66e0ea341a2a78d14336117f19763bd9be26d45d upstream.
Currently, DWC3 driver attempts to acquire the USB power supply only
once during the probe. If the USB power supply is not ready at that
time, the driver simply ignores the failure and continues the probe,
leading to permanent non-functioning of the gadget vbus_draw callback.
Address this problem by delaying the dwc3 driver initialization until
the USB power supply is registered.

usb: xhci: Fix NULL pointer dereference on certain command aborts
commit 1e0a19912adb68a4b2b74fd77001c96cd83eb073 upstream.
If a command is queued to the final usable TRB of a ring segment, the
enqueue pointer is advanced to the subsequent link TRB and no further.
If the command is later aborted, when the abort completion is handled
the dequeue pointer is advanced to the first TRB of the next segment.
If no further commands are queued, xhci_handle_stopped_cmd_ring() sees
the ring pointers unequal and assumes that there is a pending command,
so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.
Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell
ring likely is unnecessary too, but it's harmless. Leave it alone.
This is probably Bug 219532, but no confirmation has been received.
The issue has been independently reproduced and confirmed fixed using
a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.
Everything continued working normally after several prevented crashes.

In the case of a test that uses the special option ${KERNEL_VERSION} in one

example if it's a new empty directory, then the `make kernelrelease` call
will fail and the subroutine will chomp an empty string, silently. Fix that
by adding an empty configuration and retrying.

selftests/rseq: Fix handling of glibc without rseq support
commit 336d02bc4c6bec5c3d933e5d470a94970f830957 upstream.
When porting librseq commit:
commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection")
from librseq to the kernel selftests, the following line was missed
at the end of rseq_init():
rseq_size = get_rseq_kernel_feature_size();
which effectively leaves rseq_size initialized to -1U when glibc does not
have rseq support. glibc supports rseq from version 2.35 onwards.
In a following librseq commit
commit c67d198627c2 ("Only set 'rseq_size' on first thread registration")
to mimic the libc behavior, a new approach is taken: don't set the
feature size in 'rseq_size' until at least one thread has successfully
registered. This allows using 'rseq_size' in fast-paths to test for both
registration status and available features. The caveat is that on libc
either all threads are registered or none are, while with bare librseq
it is the responsability of the user to register all threads using rseq.
This combines the changes from the following librseq git commits:
commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection")
commit c67d198627c2 ("Only set 'rseq_size' on first thread registration")

netfilter: nf_tables: reject mismatching sum of field_len with set key length
commit 1b9335a8000fb70742f7db10af314104b6ace220 upstream.
The field length description provides the length of each separated key
field in the concatenation, each field gets rounded up to 32-bits to
calculate the pipapo rule width from pipapo_init(). The set key length
provides the total size of the key aligned to 32-bits.
Register-based arithmetics still allows for combining mismatching set
key length and field length description, eg. set key length 10 and field
description [ 5, 4 ] leading to pipapo width of 12.

Replace lz4c with lz4 for kernel image compression.
Although lz4 and lz4c are functionally similar, lz4c has been deprecated
upstream since 2018. Since as early as Ubuntu 16.04 and Fedora 25, lz4
and lz4c have been packaged together, making it safe to update the
requirement from lz4c to lz4.
Consequently, some distributions and build systems, such as OpenEmbedded,
have fully transitioned to using lz4. OpenEmbedded core adopted this
change in commit fe167e082cbd ("bitbake.conf: require lz4 instead of
lz4c"), causing compatibility issues when building the mainline kernel
in the latest OpenEmbedded environment, as seen in the errors below.
This change also updates the LZ4 compression commands to make it backward
compatible by replacing stdin and stdout with the '-' option, due to some
unclear reason, the stdout keyword does not work for lz4 and '-' works for
both. In addition, this modifies the legacy '-c1' with '-9' which is also
compatible with both. This fixes the mainline kernel build failures with
the latest master OpenEmbedded builds associated with the mentioned
compatibility issues.

Revert "SUNRPC: Reduce thread wake-up rate when receiving large RPC messages"
commit 966a675da844f1a764bb44557c21561cc3d09840 upstream.
I noticed that a handful of NFSv3 fstests were taking an
unexpectedly long time to run. Troubleshooting showed that the
server's TCP window closed and never re-opened, which caused the
client to trigger an RPC retransmit timeout after 180 seconds.
The client's recovery action was to establish a fresh connection
and retransmit the timed-out requests. This worked, but it adds a
long delay.
I tracked the problem to the commit that attempted to reduce the
rate at which the network layer delivers TCP socket data_ready
callbacks. Under most circumstances this change worked as expected,
but for NFSv3, which has no session or other type of throttling, it
can overwhelm the receiver on occasion.
I'm sure I could tweak the lowat settings, but the small benefit
doesn't seem worth the bother. Just revert it.

NFSD: Reset cb_seq_status after NFS4ERR_DELAY
commit 961b4b5e86bf56a2e4b567f81682defa5cba957e upstream.
I noticed that once an NFSv4.1 callback operation gets a
NFS4ERR_DELAY status on CB_SEQUENCE and then the connection is lost,
the callback client loops, resending it indefinitely.
The switch arm in nfsd4_cb_sequence_done() that handles
NFS4ERR_DELAY uses rpc_restart_call() to rearm the RPC state machine
for the retransmit, but that path does not call the rpc_prepare_call
callback again. Thus cb_seq_status is set to -10008 by the first
NFS4ERR_DELAY result, but is never set back to 1 for the retransmits.
nfsd4_cb_sequence_done() thinks it's getting nothing but a
long series of CB_SEQUENCE NFS4ERR_DELAY replies.

f2fs: Introduce linear search for dentries
commit 91b587ba79e1b68bb718d12b0758dbcdab4e9cb7 upstream.
This patch addresses an issue where some files in case-insensitive
directories become inaccessible due to changes in how the kernel function,
utf8_casefold(), generates case-folded strings from the commit 5c26d2f1d3f5
("unicode: Don't special case ignorable code points").
F2FS uses these case-folded names to calculate hash values for locating
dentries and stores them on disk. Since utf8_casefold() can produce
different output across kernel versions, stored hash values and newly
calculated hash values may differ. This results in affected files no
longer being found via the hash-based lookup.
To resolve this, the patch introduces a linear search fallback.
If the initial hash-based search fails, F2FS will sequentially scan the
directory entries.

kconfig: require a space after '#' for valid input
[ Upstream commit 4d137ab0107ead0f2590fc0314e627431e3b9e3f ]
Currently, when an input line starts with '#', (line + 2) is passed to
memcmp() without checking line[1].
It means that line[1] can be any arbitrary character. For example,
"#KCONFIG_FOO is not set" is accepted as valid input, functioning the
same as "# CONFIG_FOO is not set".
More importantly, this can potentially lead to a buffer overrun if
line[1] == '\0'. It occurs if the input only contains '#', as
(line + 2) points to an uninitialized buffer.
Check line[1], and skip the line if it is not a space.

kconfig: fix file name in warnings when loading KCONFIG_DEFCONFIG_LIST

Most 'make *config' commands use .config as the base configuration file.

SMB1 callback get_cifs_acl_by_fid() currently ignores its last argument and
therefore ignores request for SACL_SECINFO. Fix this issue by correctly
propagating info argument from get_cifs_acl() and get_cifs_acl_by_fid() to
CIFSSMBGetCIFSACL() function and pass SACL_SECINFO when requested.
For accessing SACLs it is needed to open object with SYSTEM_SECURITY
access. Pass this flag when trying to get or set SACLs.
Same logic is in the SMB2+ code path.

ASoC: rockchip: i2s_tdm: Re-add the set_sysclk callback
[ Upstream commit 5323186e2e8d33c073fad51e24f18e2d6dbae2da ]
In commit
9e2ab4b18ebd ("ASoC: rockchip: i2s-tdm: Fix inaccurate sampling rates"),
the set_sysclk callback was removed as considered unused as the mclk rate
can be set in the hw_params callback.
The difference between hw_params and set_sysclk is that the former is
called with the audio sampling rate set in the params (e.g.: 48000 Hz)
while the latter is called with a clock rate already computed with
sampling_rate * mclk-fs (e.g.: 48000 * 256)
For HDMI audio using the Rockchip I2S TDM driver, the mclk-fs value must
be set to 128 instead of the default 256, and that value is set in the
device tree at the machine driver level (like a simple-audio-card
compatible node).
Therefore, the i2s_tdm driver has no idea that another mclk-fs value can
be configured and simply computes the mclk rate in the hw_params callback
with DEFAULT_MCLK_FS * params_rate(params), which is wrong for HDMI
audio.
Re-add the set_sysclk callback so that the mclk rate is computed by the
machine driver which has the correct mclk-fs value set in its device tree
node.

[ Upstream commit cd140ce9f611a5e9d2a5989a282b75e55c71dab3 ]
Convert the hostfs filesystem to the new internal mount API as the old
one will be obsoleted and removed. This allows greater flexibility in
communication of mount parameters between userspace, the VFS and the
filesystem.
See Documentation/filesystems/mount_api.txt for more information.

genksyms: fix memory leak when the same symbol is read from *.symref file
[ Upstream commit be2fa44b5180a1f021efb40c55fdf63c249c3209 ]
When a symbol that is already registered is read again from *.symref
file, __add_symbol() removes the previous one from the hash table without
freeing it.
[Test Case]
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) {}
EXPORT_SYMBOL(foo);
$ cat foo.symref
foo void foo ( void )
foo void foo ( void )
When a symbol is removed from the hash table, it must be freed along
with its ->name and ->defn members. However, sym->name cannot be freed
because it is sometimes shared with node->string, but not always. If
sym->name and node->string share the same memory, free(sym->name) could
lead to a double-free bug.
To resolve this issue, always assign a strdup'ed string to sym->name.

genksyms: fix memory leak when the same symbol is added from source
[ Upstream commit 45c9c4101d3d2fdfa00852274bbebba65fcc3cf2 ]
When a symbol that is already registered is added again, __add_symbol()
returns without freeing the symbol definition, making it unreachable.
The following test cases demonstrate different memory leak points.
[Test Case 1]
Forward declaration with exactly the same definition
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) {}
EXPORT_SYMBOL(foo);
[Test Case 2]
Forward declaration with a different definition (e.g. attribute)
$ cat foo.c
#include <linux/export.h>
void foo(void);
__attribute__((__section__(".ref.text"))) void foo(void) {}
EXPORT_SYMBOL(foo);
[Test Case 3]
Preserving an overridden symbol (compile with KBUILD_PRESERVE=1)
$ cat foo.c
#include <linux/export.h>
void foo(void);
void foo(void) { }
EXPORT_SYMBOL(foo);
$ cat foo.symref
override foo void foo ( int )
The memory leaks in Test Case 1 and 2 have existed since the introduction
of genksyms into the kernel tree. [1]
The memory leak in Test Case 3 was introduced by commit 5dae9a550a74
("genksyms: allow to ignore symbol checksum changes").
When multiple init_declarators are reduced to an init_declarator_list,
the decl_spec must be duplicated. Otherwise, the following Test Case 4
would result in a double-free bug.
[Test Case 4]
$ cat foo.c
#include <linux/export.h>
extern int foo, bar;
int foo, bar;
EXPORT_SYMBOL(foo);
In this case, 'foo' and 'bar' share the same decl_spec, 'int'. It must
be unshared before being passed to add_symbol().

Apparently skb->mac_len is not correct for VLAN traffic as

Use instead pskb_may_pull() to make sure the expected header

net: xdp: Disallow attaching device-bound programs in generic mode
[ Upstream commit 3595599fa8360bb3c7afa7ee50c810b4a64106ea ]
Device-bound programs are used to support RX metadata kfuncs. These
kfuncs are driver-specific and rely on the driver context to read the
metadata. This means they can't work in generic XDP mode. However, there
is no check to disallow such programs from being attached in generic
mode, in which case the metadata kfuncs will be called in an invalid
context, leading to crashes.
Fix this by adding a check to disallow attaching device-bound programs
in generic mode.

tcp: correct handling of extreme memory squeeze
[ Upstream commit 8c670bdfa58e48abad1d5b6ca1ee843ca91f7303 ]
Testing with iperf3 using the "pasta" protocol splicer has revealed
a problem in the way tcp handles window advertising in extreme memory
squeeze situations.
Under memory pressure, a socket endpoint may temporarily advertise
a zero-sized window, but this is not stored as part of the socket data.
The reasoning behind this is that it is considered a temporary setting
which shouldn't influence any further calculations.
However, if we happen to stall at an unfortunate value of the current
window size, the algorithm selecting a new value will consistently fail
to advertise a non-zero window once we have freed up enough memory.
This means that this side's notion of the current window size is
different from the one last advertised to the peer, causing the latter
to not send any data to resolve the sitution.
The problem occurs on the iperf3 server side, and the socket in question
is a completely regular socket with the default settings for the
fedora40 kernel. We do not use SO_PEEK or SO_RCVBUF on the socket.
The following excerpt of a logging session, with own comments added,
shows more in detail what is happening:

Note that well behaved endpoints will send win0 probes, so the problem
will not occur.
Furthermore, we have observed that in these situations this side may
send out an updated 'th->ack_seq´ which is not stored in tp->rcv_wup
as it should be. Backing ack_seq seems to be harmless, but is of
course still wrong from a protocol viewpoint.
We fix this by updating the socket state correctly when a packet has
been dropped because of memory exhaustion and we have to advertize
a zero window.
Further testing shows that the connection recovers neatly from the
squeeze situation, and traffic can continue indefinitely.

bgmac: reduce max frame size to support just MTU 1500
[ Upstream commit 752e5fcc2e77358936d36ef8e522d6439372e201 ]
bgmac allocates new replacement buffer before handling each received
frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU
time. Ideally bgmac should just respect currently set MTU but it isn't
the case right now. For now just revert back to the old limited frame
size.
This change bumps NAT masquerade speed by ~95%.
Since commit 8218f62c9c9b ("mm: page_frag: use initial zero offset for
page_frag_alloc_align()"), the bgmac driver fails to open its network
interface successfully and runs out of memory in the following call
stack:
bgmac_open
-> bgmac_dma_init
-> bgmac_dma_rx_skb_for_slot
-> netdev_alloc_frag
BGMAC_RX_ALLOC_SIZE = 10048 and PAGE_FRAG_CACHE_MAX_SIZE = 32768.
Eventually we land into __page_frag_alloc_align() with the following
parameters across multiple successive calls:
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=0
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=10048
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=20096
__page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=30144
So in that case we do indeed have offset + fragsz (40192) > size (32768)
and so we would eventually return NULL. Reverting to the older 1500
bytes MTU allows the network driver to be usable again.

perf trace: Fix runtime error of index out of bounds
[ Upstream commit c7b87ce0dd10b64b68a0b22cb83bbd556e28fe81 ]
libtraceevent parses and returns an array of argument fields, sometimes
larger than RAW_SYSCALL_ARGS_NUM (6) because it includes "__syscall_nr",
idx will traverse to index 6 (7th element) whereas sc->fmt->arg holds 6
elements max, creating an out-of-bounds access. This runtime error is
found by UBsan. The error message:
$ sudo UBSAN_OPTIONS=print_stacktrace=1 ./perf trace -a --max-events=1
builtin-trace.c:1966:35: runtime error: index 6 out of bounds for type 'syscall_arg_fmt [6]'

net: stmmac: Limit FIFO size by hardware capability
[ Upstream commit 044f2fbaa2725696ecbf1f02ba7ab0a8ccb7e1ae ]
Tx/Rx FIFO size is specified by the parameter "{tx,rx}-fifo-depth" from
stmmac_platform layer.
However, these values are constrained by upper limits determined by the
capabilities of each hardware feature. There is a risk that the upper
bits will be truncated due to the calculation, so it's appropriate to
limit them to the upper limit values and display a warning message.
This only works if the hardware capability has the upper limit values.

Pointer arguments passed to ioctls need to pass through compat_ptr() to

Detect compat mode at runtime and call compat_ptr() for those commands

dm is netdev private data and it cannot be

can cause UAF bug. Fix it by moving free_netdev() at the end of the

iavf: allow changing VLAN state without calling PF
[ Upstream commit ee7d79433d783346430ee32f28c9df44a88b3bb6 ]
First case:
> ip l a l $VF name vlanx type vlan id 100
> ip l d vlanx
> ip l a l $VF name vlanx type vlan id 100
As workqueue can be execute after sometime, there is a window to have
call trace like that:
- iavf_del_vlan
- iavf_add_vlan
- iavf_del_vlans (wq)
It means that our VLAN 100 will change the state from IAVF_VLAN_ACTIVE
to IAVF_VLAN_REMOVE (iavf_del_vlan). After that in iavf_add_vlan state
won't be changed because VLAN 100 is on the filter list. The final
result is that the VLAN 100 filter isn't added in hardware (no
iavf_add_vlans call).
To fix that change the state if the filter wasn't removed yet directly
to active. It is save as IAVF_VLAN_REMOVE means that virtchnl message
wasn't sent yet.
Second case:
> ip l a l $VF name vlanx type vlan id 100
Any type of VF reset ex. change trust
> ip l s $PF vf $VF_NUM trust on
> ip l d vlanx
> ip l a l $VF name vlanx type vlan id 100
In case of reset iavf driver is responsible for readding all filters
that are being used. To do that all VLAN filters state are changed to
IAVF_VLAN_ADD. Here is even longer window for changing VLAN state from
kernel side, as workqueue isn't called immediately. We can have call
trace like that:
- changing to IAVF_VLAN_ADD (after reset)
- iavf_del_vlan (called from kernel ops)
- iavf_del_vlans (wq)
Not exsisitng VLAN filters will be removed from hardware. It isn't a
bug, ice driver will handle it fine. However, we can have call trace
like that:
- changing to IAVF_VLAN_ADD (after reset)
- iavf_del_vlan (called from kernel ops)
- iavf_add_vlan (called from kernel ops)
- iavf_del_vlans (wq)
With fix for previous case we end up with no VLAN filters in hardware.
We have to remove VLAN filters if the state is IAVF_VLAN_ADD and delete
VLAN was called. It is save as IAVF_VLAN_ADD means that virtchnl message
wasn't sent yet.

PM: hibernate: Add error handling for syscore_suspend()
[ Upstream commit e20a70c572539a486dbd91b225fa6a194a5e2122 ]
In hibernation_platform_enter(), the code did not check the
return value of syscore_suspend(), potentially leading to a
situation where syscore_resume() would be called even if
syscore_suspend() failed. This could cause unpredictable
behavior or system instability.
Modify the code sequence in question to properly handle errors returned
by syscore_suspend(). If an error occurs in the suspend path, the code
now jumps to label 'Enable_irqs' skipping the syscore_resume() call and
only enabling interrupts after setting the system state to SYSTEM_RUNNING.

net: hns3: fix oops when unload drivers paralleling

When unload hclge driver, it tries to disable sriov first for each
ae_dev node from hnae3_ae_dev_list. If user unloads hns3 driver at
the time, because it removes all the ae_dev nodes, and it may cause
oops.
But we can't simply use hnae3_common_lock for this. Because in the
process flow of pci_disable_sriov(), it will trigger the remove flow
of VF, which will also take hnae3_common_lock.
To fixes it, introduce a new mutex to protect the unload process.

[ Upstream commit 09471d8f5b390883eaf21b917c4bf3ced1b8a1df ]
The TOY_MATCH0_REG should be cleared to 0 in the RTC interrupt handler,
otherwise the interrupt cannot be cleared, which will cause the
loongson_rtc_isr() to be triggered multiple times.
The previous code cleared TOY_MATCH0_REG in the loongson_rtc_handler(),
which is an ACPI interrupt. This did not prevent loongson_rtc_isr()
from being triggered multiple times.
This commit moves the clearing of TOY_MATCH0_REG to the
loongson_rtc_isr() to ensure that the interrupt is properly cleared.

The nvmem interface supports variable buffer sizes, while the regmap
interface operates with fixed-size storage. If an nvmem client uses a
buffer size less than 4 bytes, regmap_read will write out of bounds
as it expects the buffer to point at an unsigned int.
Fix this by using an intermediary unsigned int to hold the value.

xfrm: delete intermediate secpath entry in packet offload mode
[ Upstream commit 600258d555f0710b9c47fb78d2d80a4aecd608cc ]
Packets handled by hardware have added secpath as a way to inform XFRM
core code that this path was already handled. That secpath is not needed
at all after policy is checked and it is removed later in the stack.
However, in the case of IP forwarding is enabled (/proc/sys/net/ipv4/ip_forward),
that secpath is not removed and packets which already were handled are reentered
to the driver TX path with xfrm_offload set.
The following kernel panic is observed in mlx5 in such case:

xfrm: replay: Fix the update of replay_esn->oseq_hi for GSO
[ Upstream commit c05c5e5aa163f4682ca97a2f0536575fc7dbdecb ]
When skb needs GSO and wrap around happens, if xo->seq.low (seqno of
the first skb segment) is before the last seq number but oseq (seqno
of the last segment) is after it, xo->seq.low is still bigger than
replay_esn->oseq while oseq is smaller than it, so the update of
replay_esn->oseq_hi is missed for this case wrap around because of
the change in the cited commit.
For example, if sending a packet with gso_segs=3 while old
replay_esn->oseq=0xfffffffe, we calculate:
xo->seq.low = 0xfffffffe + 1 = 0x0xffffffff
oseq = 0xfffffffe + 3 = 0x1
(oseq < replay_esn->oseq) is true, but (xo->seq.low <
replay_esn->oseq) is false, so replay_esn->oseq_hi is not incremented.
To fix this issue, change the outer checking back for the update of
replay_esn->oseq_hi. And add new checking inside for the update of
packet's oseq_hi.

resulting in a thread switch and causing the CPU to be in an interrupt
enabled state after the enable_gpe_wakeup() function returns, leading
to the warnings as follow.

The root cause is acpi_enable_all_wakeup_gpes() uses a mutex to protect
acpi_hw_enable_all_wakeup_gpes(), and acpi_ut_acquire_mutex() may cause
a thread switch. Since there is no longer concurrent execution during
loongarch_acpi_suspend(), we can call acpi_hw_enable_all_wakeup_gpes()
directly in enable_gpe_wakeup().
The solution is similar to commit 22db06337f590d01 ("ACPI: sleep: Avoid
breaking S3 wakeup due to might_sleep()").

serial: 8250: Adjust the timeout for FIFO mode
[ Upstream commit d91f98be26510f5f81ec66425bb0306d1ccd571a ]
After a console has written a record into UART_TX, it uses
wait_for_xmitr() to wait until the data has been sent out before
returning. However, wait_for_xmitr() will timeout after 10ms,
regardless if the data has been transmitted or not.
For single bytes, this timeout is sufficient even at very slow
baud rates, such as 1200bps. However, when FIFO mode is used,
there may be 64 bytes pushed into the FIFO at once. At a baud
rate of 115200bps, the 10ms timeout is still sufficient. But
when using lower baud rates (such as 57600bps), the timeout
is _not_ sufficient. This causes longer lines to be cut off,
resulting in lost and horribly misformatted output on the
console.
When using FIFO mode, take the number of bytes into account to
determine an appropriate maximum timeout. Increasing the timeout
does not affect performance since ideally the timeout never
occurs.

driver core: class: Fix wild pointer dereferences in API class_dev_iter_next()
[ Upstream commit e128f82f7006991c99a58114f70ef61e937b1ac1 ]
There are a potential wild pointer dereferences issue regarding APIs
class_dev_iter_(init|next|exit)(), as explained by below typical usage:
// All members of @iter are wild pointers.
struct class_dev_iter iter;
// class_dev_iter_init(@iter, @class, ...) checks parameter @class for
// potential class_to_subsys() error, and it returns void type and does
// not initialize its output parameter @iter, so caller can not detect
// the error and continues to invoke class_dev_iter_next(@iter) even if
// @iter still contains wild pointers.
class_dev_iter_init(&iter, ...);
// Dereference these wild pointers in @iter here once suffer the error.
while (dev = class_dev_iter_next(&iter)) { ... };
// Also dereference these wild pointers here.
class_dev_iter_exit(&iter);
Actually, all callers of these APIs have such usage pattern in kernel tree.
Fix by:
- Initialize output parameter @iter by memset() in class_dev_iter_init()
and give callers prompt by pr_crit() for the error.
- Check if @iter is valid in class_dev_iter_next().

nilfs2: protect access to buffers with no active references
[ Upstream commit 367a9bffabe08c04f6d725032cce3d891b2b9e1a ]
nilfs_lookup_dirty_data_buffers(), which iterates through the buffers
attached to dirty data folios/pages, accesses the attached buffers without
locking the folios/pages.
For data cache, nilfs_clear_folio_dirty() may be called asynchronously
when the file system degenerates to read only, so
nilfs_lookup_dirty_data_buffers() still has the potential to cause use
after free issues when buffers lose the protection of their dirty state
midway due to this asynchronous clearing and are unintentionally freed by
try_to_free_buffers().
Eliminate this race issue by adjusting the lock section in this function.

buffer: make folio_create_empty_buffers() return a buffer_head
[ Upstream commit 3decb8564eff88a2533f83b01cec2cf9259c3eaf ]
Patch series "Finish the create_empty_buffers() transition", v2.
Pankaj recently added folio_create_empty_buffers() as the folio equivalent
to create_empty_buffers(). This patch set finishes the conversion by
first converting all remaining filesystems to call
folio_create_empty_buffers(), then renaming it back to
create_empty_buffers(). I took the opportunity to make a few
simplifications like making folio_create_empty_buffers() return the head
buffer and extracting get_nth_bh() from nilfs2.
A few of the patches in this series aren't directly related to
create_empty_buffers(), but I saw them while I was working on this and
thought they'd be easy enough to add to this series. Compile-tested only,
other than ext4.
This patch (of 26):
Almost all callers want to know the first BH that was allocated for this
folio. We already have that handy, so return it.

PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()
[ Upstream commit 2d2da5a4c1b4509f6f7e5a8db015cd420144beb4 ]
The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region()
macro to request a needed resource. A string variable that lives on the
stack is then used to store a dynamically computed resource name, which
is then passed on as one of the macro arguments. This can lead to
undefined behavior.
Depending on the current contents of the memory, the manifestations of
errors may vary. One possible output may be as follows:
$ cat /proc/iomem
30000000-37ffffff :
38000000-3fffffff :
Sometimes, garbage may appear after the colon.
In very rare cases, if no NULL-terminator is found in memory, the system
might crash because the string iterator will overrun which can lead to
access of unmapped memory above the stack.
Thus, fix this by replacing outbound_name with the name of the previously
requested resource. With the changes applied, the output will be as
follows:
$ cat /proc/iomem
30000000-37ffffff : memory2
38000000-3fffffff : memory3

[ Upstream commit 094f5c315f756b19198e6c401aa821ac0e868750 ]
imx_media_add_of_subdevs() calls of_parse_phandle() and passes the
obtained node to imx_media_of_add_csi(). The passed node is used in
v4l2_async_nf_add_fwnode(), which increments the refcount of the node.
Therefore, while the current implementation only releases the node when
imx_media_of_add_csi() fails, but should always release it. Call
of_node_put() right after imx_media_of_add_csi().

mtd: hyperbus: hbmc-am654: Convert to platform remove callback returning void
[ Upstream commit 59bd56760df17506bc2f828f19b40a2243edd0d0 ]
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

devres_release() instead of devres_destroy() so the EPC device will be
released.

[ Upstream commit e24c1551059268b37f6f40639883eafb281b8b9c ]
Resolve a UBSAN shift-out-of-bounds issue in iova_bitmap_offset_to_index()
where shifting the constant "1" (of type int) by bitmap->mapped.pgshift
(an unsigned long value) could result in undefined behavior.
The constant "1" defaults to a 32-bit "int", and when "pgshift" exceeds
31 (e.g., pgshift = 63) the shift operation overflows, as the result
cannot be represented in a 32-bit type.
To resolve this, the constant is updated to "1UL", promoting it to an

of: reserved-memory: Do not make kmemleak ignore freed address

early_init_dt_alloc_reserved_memory_arch() will free address @base when
suffers memblock_mark_nomap() error, but it still makes kmemleak ignore
the freed address @base via kmemleak_ignore_phys().
That is unnecessary, besides, also causes unnecessary warning messages:
kmemleak_ignore_phys()
-> make_black_object()
-> paint_ptr()
-> kmemleak_warn() // warning message here.
Fix by avoiding kmemleak_ignore_phys() when suffer the error.

RDMA/mlx5: Fix indirect mkey ODP page count
[ Upstream commit 235f238402194a78ac5fb882a46717eac817e5d1 ]
Restrict the check for the number of pages handled during an ODP page
fault to direct mkeys.
Perform the check right after handling the page fault and don't
propagate the number of handled pages to callers.
Indirect mkeys and their associated direct mkeys can have different
start addresses. As a result, the calculation of the number of pages to
handle for an indirect mkey may not match the actual page fault
handling done on the direct mkey.
For example:
A 4K sized page fault on a KSM mkey that has a start address that is not
aligned to a page will result a calculation that assumes the number of
pages required to handle are 2.
While the underlying MTT might be aligned will require fetching only a
single page.
Thus, do the calculation and compare number of pages handled only per
direct mkey.

i3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition
[ Upstream commit b75439c945b94dd8a2b645355bdb56f948052601 ]
In dw_i3c_common_probe, &master->hj_work is bound with
dw_i3c_hj_work. And dw_i3c_master_irq_handler can call
dw_i3c_master_irq_handle_ibis function to start the work.
If we remove the module which will call dw_i3c_common_remove to
make cleanup, it will free master->base through i3c_master_unregister
while the work mentioned above will be used. The sequence of operations
that may lead to a UAF bug is as follows:
CPU0 CPU1
| dw_i3c_hj_work
dw_i3c_common_remove |
i3c_master_unregister(&master->base) |
device_unregister(&master->dev) |
device_release |
//free master->base |
| i3c_master_do_daa(&master->base)
| //use master->base
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in dw_i3c_common_remove.

arm64: dts: qcom: Add SM7125 device tree
[ Upstream commit 72fbf05149bd451e7222c2ed1e3823972f19df9c ]
The Snapdragon 720G (sm7125) is software-wise very similar to the
Snapdragon 7c with minor differences in clock speeds and as added here,
it uses the Kryo 465 instead of Kryo 468.

arm64: dts: allwinner: a64: explicitly assign clock parent for TCON0
[ Upstream commit 8715c91a836502929c637c76a26335ede8818acf ]
TCON0 seems to need a different clock parent depending on output type.
For RGB it has to be PLL-VIDEO0-2X, while for DSI it has to be PLL-MIPI,
so select it explicitly.
Video output doesn't work if incorrect clock is assigned.
On my Pinebook I manually configured PLL-VIDEO0-2X and PLL-MIPI to the same
rate, and while video output works fine with PLL-VIDEO0-2X, it doesn't
work at all (as in no picture) with PLL-MIPI.

Add no-1-8-v property to sdmmc0 node to keep VDDSDMMC power rail at 3.3V.
This property will stop the LDO regulator from switching to 1.8V when the
MMC core detects an UHS SD Card. VDDSDMMC power rail is used by all the
SDMMC interface pins in GPIO mode (PA0 - PA13).
On this board, PA10 is used as GPIO to enable the power switch controlling
USB Vbus for the USB Host. The change is needed to fix the PA10 voltage
level to 3.3V instead of 1.8V.

[ Upstream commit b9784e5cde1f9fb83661a70e580e381ae1264d12 ]
As of_find_node_by_name() release the reference of the argument device
node, tegra_emc_find_node_by_ram_code() releases some device nodes while
still in use, resulting in possible UAFs. According to the bindings and
the in-tree DTS files, the "emc-tables" node is always device's child
node with the property "nvidia,use-ram-code", and the "lpddr2" node is a
child of the "emc-tables" node. Thus utilize the
for_each_child_of_node() macro and of_get_child_by_name() instead of
of_find_node_by_name() to simplify the code.
This bug was found by an experimental verification tool that I am
developing.

[ Upstream commit 3d7fdd8e38aafd4858935df2392762c1ab8fb40f ]
The MAC reset for PCIe port 1 on MT8195 when asserted during suspend
causes the system to hang during resume with the following error (with
no_console_suspend enabled):
mtk-pcie-gen3 112f8000.pcie: PCIe link down, current LTSSM state: detect.quiet (0x0)

mtk-pcie-gen3 112f8000.pcie: PM: failed to resume noirq: error -110
This issue is specific to MT8195. On MT8192 with the PCIe reset,
MT8192_INFRA_RST4_PCIE_TOP_SWRST, added to the DT node, the issue is not
observed.
Since without the reset, the PCIe controller and WiFi card connected to
it, work just as well, remove the reset to allow the system to suspend
and resume properly.

RDMA/srp: Fix error handling in srp_add_port
[ Upstream commit a3cbf68c69611188cd304229e346bffdabfd4277 ]
As comment of device_add() says, if device_add() succeeds, you should
call device_del() when you want to get rid of it. If device_add() has
not succeeded, use only put_device() to drop the reference count.
Add a put_device() call before returning from the function to decrement
reference count for cleanup.
Found by code review.

RDMA/rxe: Improve newline in printing messages
[ Upstream commit 6482718086bf69f9616d0b86d03514b17afaeb08 ]
Previously rxe_{dbg,info,err}() macros are appended built-in newline,
but some users will add redundant newline sometimes. So remove the
built-in newline for these macros.
In terms of rxe_{dbg,info,err}_xxx() macros, because they don't have
built-in newline, append newline when using them.

direct events is not used by EXTI and is propagated to the parent
IRQ controller of EXTI, the GIC.
Align the IRQ type to the value expected by the GIC by replacing
the second parameter "1" with IRQ_TYPE_LEVEL_HIGH.

arm64: dts: mediatek: mt8186: Move wakeup to MTU3 to get working suspend
[ Upstream commit 253b4e96f5783fddede1b82274a7b4e0aa57d761 ]
The current DT has the wakeup-source and mediatek,syscon-wakeup
properties in the XHCI nodes, which configures USB wakeup after powering
down the XHCI hardware block. However, since the XHCI controller is
behind an MTU3 (USB3 DRD controller), the MTU3 only gets powered down
after USB wakeup has been configured, causing the system to detect a
wakeup, and results in broken suspend support as the system resumes
immediately.
Move the wakeup properties to the MTU3 nodes so that USB wakeup is only
enabled after the MTU3 has powered down.
With this change in place, it is possible to suspend and resume, and
also to wakeup through USB, as tested on the Google Steelix (Lenovo 300e
Yoga Chromebook Gen 4).

ARM: at91: pm: change BU Power Switch to automatic mode
[ Upstream commit 6fc5bdfa872b7da51b5507a1327a17c3db2fcf95 ]
Change how the Backup Unit Power is configured and force the
automatic/hardware mode.
This change eliminates the need for software management of the power
switch, ensuring it transitions to the backup power source before
entering low power modes.
This is done in the only location where this switch was configured. It's
usually done in the bootloader.
Previously, the loss of the VDDANA (or VDDIN33) power source was not
automatically compensated by an alternative power source. This resulted
in the loss of Backup Unit content, including Backup Self-refresh low
power mode information, OTP emulation configuration, and boot
configuration, for instance.

A device_node acquired via of_find_node_by_path() requires explicit
calls to of_node_put() when it is no longer needed to avoid leaking the
resource.
Instead of adding the missing calls to of_node_put() in all execution
paths, use the cleanup attribute for 'np' by means of the __free()

padata: avoid UAF for reorder_work
[ Upstream commit dd7d37ccf6b11f3d95e797ebe4e9e886d0332600 ]
Although the previous patch can avoid ps and ps UAF for _do_serial, it
can not avoid potential UAF issue for reorder_work. This issue can
happen just as below:
crypto_request crypto_request crypto_del_alg
padata_do_serial
...
padata_reorder
// processes all remaining
// requests then breaks
while (1) {
if (!padata)
break;
...
}
padata_do_serial
// new request added
list_add
// sees the new request
queue_work(reorder_work)
padata_reorder
queue_work_on(squeue->work)
...
<kworker context>
padata_serial_worker
// completes new request,
// no more outstanding
// requests
crypto_del_alg
// free pd
<kworker context>
invoke_padata_reorder
// UAF of pd
To avoid UAF for 'reorder_work', get 'pd' ref before put 'reorder_work'
into the 'serial_wq' and put 'pd' ref until the 'serial_wq' finish.

If 'mdelay(10)' is added before calling 'padata_find_next' in the
'padata_reorder' function, this issue could be reproduced easily with
ltp test (pcrypt_aead01).
This can be explained as bellow:
pcrypt_aead_encrypt
...
padata_do_parallel
refcount_inc(&pd->refcnt); // add refcnt
...
padata_do_serial
padata_reorder // pd
while (1) {
padata_find_next(pd, true); // using pd
queue_work_on
...
padata_serial_worker crypto_del_alg
padata_put_pd_cnt // sub refcnt
padata_free_shell
padata_put_pd(ps->pd);
// pd is freed
// loop again, but pd is freed
// call padata_find_next, UAF
}
In the padata_reorder function, when it loops in 'while', if the alg is
deleted, the refcnt may be decreased to 0 before entering
'padata_find_next', which leads to UAF.
As mentioned in [1], do_serial is supposed to be called with BHs disabled
and always happen under RCU protection, to address this issue, add
synchronize_rcu() in 'padata_free_shell' wait for all _do_serial calls
to finish.

[ Upstream commit 1be9264158ef4818393e5d8144887a1a5d3cc480 ]
`parse_lock_type` can only add the first lock flag in `lock_type_table`
given input `str`. For example, for `Y rwlock`, it only adds `rwlock:R`
into this perf session. Another example is for `-Y mutex`, it only adds
the mutex without `LCB_F_SPIN` flag. The patch fixes this issue, makes
sure both `rwlock:R` and `rwlock:W` will be added with `-Y rwlock`, and
so on.

pinctrl: amd: Take suspend type into consideration which pins are non-wake
[ Upstream commit f31f33dbb3bab572bad9fe7b849ab0dcbe6fd279 ]
Some laptops have pins which are a wake source for S0i3/S3 but which
aren't a wake source for S4/S5 and which cause issues when left unmasked
during hibernation (S4).
For example HP EliteBook 855 G7 has pin #24 that causes instant wakeup
(hibernation failure) if left unmasked (it is a wake source only for
S0i3/S3).
GPIO pin #24 on this platform is likely dedicated to WWAN XMM7360
modem since this pin triggers wake notify to WWAN modem's parent PCIe
port.
Fix this by considering a pin a wake source only if it is marked as one
for the current suspend type (S0i3/S3 vs S4/S5).
Since Z-wake pins only make sense at runtime these were excluded from
both of suspend categories, so pins with only the Z-wake flag set are
effectively treated as non-wake pins.

perf namespaces: Introduce nsinfo__set_in_pidns()
[ Upstream commit 9c6a585d257f6845731f4e36b45fe42b5c3162f5 ]
When we're processing a perf.data file we will, for every thread in that
file do a machine__findnew_thread(machine, pid, tid) that when that pid
is seen for the first time will create a 'struct thread' representing
it.
That in turn will call nsinfo__new() -> nsinfo__init() and there it will
assume we're running live, which is wrong and will need to be addressed
in a followup patch.
The nsinfo__new() assumes that if we can't access that thread it has
already finished and will ignore the -1 return from nsinfo__init(), just
taking notes to avoid trying to enter in that namespace, since it isn't
there anymore, a race.
When doing this from 'perf inject', tho, we can fill in parts of that
nsinfo from what we get from the PERF_RECORD_MMAP2 (pid, tid) and in the
jitdump file name, that has the form of jit-<PID>.dump.
So if the pid in the jitdump file name is not the one in the
PERF_RECORD_MMAP2, we can assume that its the pid of the process
_inside_ the namespace, and that perf was runing outside that namespace.
This will be done in the following patch.

Don't require it to be a text symbol, accept any symbol type.

this:
---
# grep -e _stext -e _etext -e _edata /proc/kallsyms

So there is no _edata and _etext is not text

perf top: Don't complain about lack of vmlinux when not resolving some kernel samples

Recently we got a case where a kernel sample wasn't being resolved due
to a bug that was not setting the end address on kernel functions
implemented in assembly (see Link: tag), and then those were not being
found by machine__resolve() -> map__find_symbol().
So we ended up with:
# perf top --stdio
PerfTop: 0 irqs/s kernel: 0% exact: 0% lost: 0/0 drop: 0/0 [cycles/P]
-----------------------------------------------------------------------
Warning:
A vmlinux file was not found.
Kernel samples will not be resolved.
^Z
[1]+ Stopped perf top --stdio
#
But then resolving all other kernel symbols.
So just fixup the logic to only print that warning when there are no
symbols in the kernel map.

corresponding to the UMP rawmidi, while we have another major knob
CONFIG_SND_SEQ_UMP that specifies whether the sequencer core supports
UMP packets or not. Strictly speaking both of them are independent,
but practically seen, it makes no sense to enable
CONFIG_SND_SEQ_UMP_CLIENT without UMP support itself.
This patch makes such an implicit dependency clearer. Now
CONFIG_SND_SEQ_UMP_CLIENT depends on both CONFIG_SND_UMP and
CONFIG_SND_SEQ_UMP. Meanwhile, CONFIG_SND_SEQ_UMP is enabled as
default when CONFIG_SND_UMP is set.

When the digest alg is HMAC-SHAx or another, the authsize may be less
than 4 bytes and mac_len of the BD is set to zero, the hardware considers
it a BD configuration error and reports a ras error, so the sec driver

[ Upstream commit fd337f852b2677b53d0859a47b58e6e6bd189f30 ]
When the AEAD algorithm is used for encryption or decryption,
the input authentication length varies, the hardware needs to
obtain the input length to pass the integrity check verification.
Currently, the driver uses a fixed authentication length,which
causes decryption failure, so the length configuration is modified.
In addition, the step of setting the auth length is unnecessary,
so it was deleted from the setkey function.

selftests/bpf: Fix fill_link_info selftest on powerpc
[ Upstream commit 4d33dc1bc31df80356c49e40dbd3ddff19500bcb ]
With CONFIG_KPROBES_ON_FTRACE enabled on powerpc, ftrace_location_range
returns ftrace location for bpf_fentry_test1 at offset of 4 bytes from
function entry. This is because branch to _mcount function is at offset
of 4 bytes in function profile sequence.
To fix this, add entry_offset of 4 bytes while verifying the address for
kprobe entry address of bpf_fentry_test1 in verify_perf_link_info in
selftest, when CONFIG_KPROBES_ON_FTRACE is enabled.
Disassemble of bpf_fentry_test1:
c000000000e4b080 <bpf_fentry_test1>:
c000000000e4b080: a6 02 08 7c mflr r0

c000000000e4b090: 20 00 80 4e blr
When CONFIG_PPC_FTRACE_OUT_OF_LINE [1] is enabled, these function profile
sequence is moved out of line with an unconditional branch at offset 0.
So, the test works without altering the offset for
'CONFIG_KPROBES_ON_FTRACE && CONFIG_PPC_FTRACE_OUT_OF_LINE' case.

libbpf: Fix segfault due to libelf functions not setting errno
[ Upstream commit e10500b69c3f3378f3dcfc8c2fe4cdb74fc844f5 ]
Libelf functions do not set errno on failure. Instead, it relies on its
internal _elf_errno value, that can be retrieved via elf_errno (or the
corresponding message via elf_errmsg()). From "man libelf":
If a libelf function encounters an error it will set an internal
error code that can be retrieved with elf_errno. Each thread
maintains its own separate error code. The meaning of each error
code can be determined with elf_errmsg, which returns a string
describing the error.
As a consequence, libbpf should not return -errno when a function from
libelf fails, because an empty value will not be interpreted as an error
and won't prevent the program to stop. This is visible in
bpf_linker__add_file(), for example, where we call a succession of
functions that rely on libelf:
err = err ?: linker_load_obj_file(linker, filename, opts, &obj);
err = err ?: linker_append_sec_data(linker, &obj);
err = err ?: linker_append_elf_syms(linker, &obj);
err = err ?: linker_append_elf_relos(linker, &obj);
err = err ?: linker_append_btf(linker, &obj);
err = err ?: linker_append_btf_ext(linker, &obj);
If the object file that we try to process is not, in fact, a correct
object file, linker_load_obj_file() may fail with errno not being set,
and return 0. In this case we attempt to run linker_append_elf_sysms()
and may segfault.

Commit f803bcf9208a ("selftests/bpf: Prevent client connect before
server bind in test_tc_tunnel.sh") added code that waits for the
netcat server to start before the netcat client attempts to connect to
it. However, not all calls to 'server_listen' were guarded.
This patch adds the existing 'wait_for_port' guard after the remaining
call to 'server_listen'.

libbpf: don't adjust USDT semaphore address if .stapsdt.base addr is missing
[ Upstream commit 98ebe5ef6f5c4517ba92fb3e56f95827ebea83fd ]
USDT ELF note optionally can record an offset of .stapsdt.base, which is
used to make adjustments to USDT target attach address. Currently,
libbpf will do this address adjustment unconditionally if it finds
.stapsdt.base ELF section in target binary. But there is a corner case
where .stapsdt.base ELF section is present, but specific USDT note
doesn't reference it. In such case, libbpf will basically just add base
address and end up with absolutely incorrect USDT target address.
This adjustment has to be done only if both .stapsdt.sema section is
present and USDT note is recording a reference to it.

tcp_cubic: fix incorrect HyStart round start detection
[ Upstream commit 25c1a9ca53db5780757e7f53e688b8f916821baa ]
I noticed that HyStart incorrectly marks the start of rounds,
leading to inaccurate measurements of ACK train lengths and
resetting the `ca->sample_cnt` variable. This inaccuracy can impact
HyStart's functionality in terminating exponential cwnd growth during
Slow-Start, potentially degrading TCP performance.
The issue arises because the changes introduced in commit 4e1fddc98d25
("tcp_cubic: fix spurious Hystart ACK train detections for not-cwnd-limited flows")
moved the caller of the `bictcp_hystart_reset` function inside the `hystart_update` function.
This modification added an additional condition for triggering the caller,
requiring that (tcp_snd_cwnd(tp) >= hystart_low_window) must also
be satisfied before invoking `bictcp_hystart_reset`.
This fix ensures that `bictcp_hystart_reset` is correctly called
at the start of a new round, regardless of the congestion window size.
This is achieved by moving the condition
(tcp_snd_cwnd(tp) >= hystart_low_window)
from before calling `bictcp_hystart_reset` to after it.
I tested with a client and a server connected through two Linux software routers.
In this setup, the minimum RTT was 150 ms, the bottleneck bandwidth was 50 Mbps,
and the bottleneck buffer size was 1 BDP, calculated as (50M / 1514 / 8) * 0.150 = 619 packets.
I conducted the test twice, transferring data from the server to the client for 1.5 seconds.
Before the patch was applied, HYSTART-DELAY stopped the exponential growth of cwnd when
cwnd = 516, and the bottleneck link was not yet saturated (516 < 619).
After the patch was applied, HYSTART-ACK-TRAIN stopped the exponential growth of cwnd when
cwnd = 632, and the bottleneck link was saturated (632 > 619).
In this test, applying the patch resulted in 300 KB more data delivered.

net: ethernet: ti: am65-cpsw: fix freeing IRQ in am65_cpsw_nuss_remove_tx_chns()
[ Upstream commit 4395a44acb15850e492dd1de9ec4b6479d96bc80 ]
When getting the IRQ we use k3_udma_glue_tx_get_irq() which returns
negative error value on error. So not NULL check is not sufficient
to deteremine if IRQ is valid. Check that IRQ is greater then zero
to ensure it is valid.
There is no issue at probe time but at runtime user can invoke
.set_channels which results in the following call chain.
am65_cpsw_set_channels()
am65_cpsw_nuss_update_tx_rx_chns()
am65_cpsw_nuss_remove_tx_chns()
am65_cpsw_nuss_init_tx_chns()
At this point if am65_cpsw_nuss_init_tx_chns() fails due to
k3_udma_glue_tx_get_irq() then tx_chn->irq will be set to a
negative value.
Then, at subsequent .set_channels with higher channel count we
will attempt to free an invalid IRQ in am65_cpsw_nuss_remove_tx_chns()
leading to a kernel warning.
The issue is present in the original commit that introduced this driver,
although there, am65_cpsw_nuss_update_tx_rx_chns() existed as
am65_cpsw_nuss_update_tx_chns().

net: sched: Disallow replacing of child qdisc from one parent to another
[ Upstream commit bc50835e83f60f56e9bec2b392fb5544f250fb6f ]
Lion Ackermann was able to create a UAF which can be abused for privilege
escalation with the following script
Step 1. create root qdisc
tc qdisc add dev lo root handle 1:0 drr
step2. a class for packet aggregation do demonstrate uaf
tc class add dev lo classid 1:1 drr
step3. a class for nesting
tc class add dev lo classid 1:2 drr
step4. a class to graft qdisc to
tc class add dev lo classid 1:3 drr
step5.
tc qdisc add dev lo parent 1:1 handle 2:0 plug limit 1024
step6.
tc qdisc add dev lo parent 1:2 handle 3:0 drr
step7.
tc class add dev lo classid 3:1 drr
step 8.
tc qdisc add dev lo parent 3:1 handle 4:0 pfifo
step 9. Display the class/qdisc layout
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 limit 1000p
qdisc drr 3: dev lo parent 1:2
step10. trigger the bug <=== prevented by this patch
tc qdisc replace dev lo parent 1:3 handle 4:0
step 11. Redisplay again the qdiscs/classes
tc class ls dev lo
class drr 1:1 root leaf 2: quantum 64Kb
class drr 1:2 root leaf 3: quantum 64Kb
class drr 1:3 root leaf 4: quantum 64Kb
class drr 3:1 root leaf 4: quantum 64Kb
tc qdisc ls
qdisc drr 1: dev lo root refcnt 2
qdisc plug 2: dev lo parent 1:1
qdisc pfifo 4: dev lo parent 3:1 refcnt 2 limit 1000p
qdisc drr 3: dev lo parent 1:2
Observe that a) parent for 4:0 does not change despite the replace request.
There can only be one parent. b) refcount has gone up by two for 4:0 and
c) both class 1:3 and 3:1 are pointing to it.
Step 12. send one packet to plug
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10001))
step13. send one packet to the grafted fifo
echo "" | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888,priority=$((0x10003))
step14. lets trigger the uaf
tc class delete dev lo classid 1:3
tc class delete dev lo classid 1:1
The semantics of "replace" is for a del/add _on the same node_ and not
a delete from one node(3:1) and add to another node (1:3) as in step10.
While we could "fix" with a more complex approach there could be
consequences to expectations so the patch takes the preventive approach of
"disallow such config".

unregistration path before being used again, but in general running
ethnl operations while dismantle has started is not a good idea.
Fix this by denying any operation on devices being unregistered. A check
was already there in ethnl_ops_begin, but not wide enough.
Note that the same issue cannot be seen on the ioctl version
(__dev_ethtool) because the device reference is retrieved from within
the rtnl lock section there. Once dismantle started, the net device is
unlisted and no reference will be found.

net: let net.core.dev_weight always be non-zero
[ Upstream commit d1f9f79fa2af8e3b45cffdeef66e05833480148a ]
The following problem was encountered during stability test:
(NULL net_device): NAPI poll function process_backlog+0x0/0x530 \
returned 1, exceeding its budget of 0.
------------[ cut here ]------------
list_add double add: new=ffff88905f746f48, prev=ffff88905f746f48, \

The reproduction command is as follows:
sysctl -w net.core.dev_weight=0
ping 127.0.0.1
This is because when the napi's weight is set to 0, process_backlog() may
return 0 and clear the NAPI_STATE_SCHED bit of napi->state, causing this
napi to be re-polled in net_rx_action() until __do_softirq() times out.
Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can
be retriggered in enqueue_to_backlog(), causing this issue.
Making the napi's weight always non-zero solves this problem.
Triggering this issue requires system-wide admin (setting is
not namespaced).

clk: analogbits: Fix incorrect calculation of vco rate delta
[ Upstream commit d7f12857f095ef38523399d47e68787b357232f6 ]
In wrpll_configure_for_rate() we try to determine the best PLL
configuration for a target rate. However, in the loop where we try
values of R, we should compare the derived `vco` with `target_vco_rate`.
However, we were in fact comparing it with `target_rate`, which is
actually after Q shift. This is incorrect, and sometimes can result in
suboptimal clock rates. Fix it.

When the scan parameters for a 6GHz scan specify a unicast
BSSID address, and the corresponding AP is found in the scan
list, add a corresponding entry in the collocated AP list,
so this AP would be directly probed even if it was not
advertised as a collocated AP.
This is needed for handling a scan request that is intended
for a ML probe flow, where user space can requests a scan
to retrieve information for other links in the AP MLD.

cpufreq: ACPI: Fix max-frequency computation
[ Upstream commit 0834667545962ef1c5e8684ed32b45d9c574acd3 ]
Commit 3c55e94c0ade ("cpufreq: ACPI: Extend frequency tables to cover
boost frequencies") introduced an assumption in acpi_cpufreq_cpu_init()
that the first entry in the P-state table was the nominal frequency.
This assumption is incorrect. The frequency corresponding to the P0
P-State need not be the same as the nominal frequency advertised via
CPPC.
Since the driver is using the CPPC.highest_perf and CPPC.nominal_perf
to compute the boost-ratio, it makes sense to use CPPC.nominal_freq to
compute the max-frequency. CPPC.nominal_freq is advertised on
platforms supporting CPPC revisions 3 or higher.
Hence, fallback to using the first entry in the P-State table only on
platforms that do not advertise CPPC.nominal_freq.

wifi: mt76: mt7915: firmware restart on devices with a second pcie link
[ Upstream commit 9b60e2ae511c959024ecf6578b3fbe85cd06d7cc ]
It seems that the firmware checks the register used for detecting matching
PCIe links in order to figure out if a secondary PCIe link is enabled.
Write the register again just before starting the firmware on hw reset,
in order to fix an issue that left the second band unusable after restart.

wifi: mt76: mt76u_vendor_request: Do not print error messages when -EPROTO
[ Upstream commit f1b1e133a770fcdbd89551651232b034d2f7a27a ]
When initializing the network card, unplugging the device will
trigger an -EPROTO error, resulting in a flood of error messages
being printed frantically.
The exception is printed as follows：
mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
...
It will continue to print more than 2000 times for about 5 minutes,
causing the usb device to be unable to be disconnected. During this
period, the usb port cannot recognize the new device because the old
device has not disconnected.
There may be other operating methods that cause -EPROTO, but -EPROTO is
a low-level hardware error. It is unwise to repeat vendor requests
expecting to read correct data. It is a better choice to treat -EPROTO
and -ENODEV the same way.
Similar to commit 9b0f100c1970 ("mt76: usb: process URBs with status
EPROTO properly") do no schedule rx_worker for urb marked with status
set -EPROTO. I also reproduced this situation when plugging and
unplugging the device, and this patch is effective.
Just do not vendor request again for urb marked with status set -EPROTO.

net/smc: fix data error when recvmsg with MSG_PEEK flag
[ Upstream commit a4b6539038c1aa1ae871aacf6e41b566c3613993 ]
When recvmsg with MSG_PEEK flag, the data will be copied to
user's buffer without advancing consume cursor and without
reducing the length of rx available data. Once the expected
peek length is larger than the value of bytes_to_rcv, in the
loop of do while in smc_rx_recvmsg, the first loop will copy
bytes_to_rcv bytes of data from the position local_tx_ctrl.cons,
the second loop will copy the min(bytes_to_rcv, read_remaining)
bytes from the position local_tx_ctrl.cons again because of the
lacking of process with advancing consume cursor and reducing
the length of available data. So do the subsequent loops. The
data copied in the second loop and the subsequent loops will
result in data error, as it should not be copied if no more data
arrives and it should be copied from the position advancing
bytes_to_rcv bytes from the local_tx_ctrl.cons if more data arrives.
This issue can be reproduce by the following python script:
server.py:
import socket
import time
server_ip = '0.0.0.0'
server_port = 12346
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind((server_ip, server_port))
server_socket.listen(1)
print('Server is running and listening for connections...')
conn, addr = server_socket.accept()
print('Connected by', addr)
while True:
data = conn.recv(1024)
if not data:
break
print('Received request:', data.decode())
conn.sendall(b'Hello, client!\n')
time.sleep(5)
conn.sendall(b'Hello, again!\n')
conn.close()
client.py:
import socket
server_ip = '<server ip>'
server_port = 12346
resp=b'Hello, client!\nHello, again!\n'
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((server_ip, server_port))
request = 'Hello, server!'
client_socket.sendall(request.encode())
peek_data = client_socket.recv(len(resp),
socket.MSG_PEEK | socket.MSG_WAITALL)
print('Peeked data:', peek_data.decode())
client_socket.close()

wifi: mac80211: fix tid removal during mesh forwarding
[ Upstream commit 3aaa1a5a9a2ceeb32afa6ea4110a92338a863c33 ]
With change (wifi: mac80211: fix receiving A-MSDU
frames on mesh interfaces), a non-zero TID assignment
is lost during slow path mesh forwarding.
Prior to this change, ieee80211_rx_h_mesh_fwding()
left the TID intact in the header.
As a result of this header corruption, packets belonging
to non-zero TIDs will get treating as belonging
TID 0 by functions such as ieee80211_get_tid().
While this miscategorization by itself is an
issue, there are additional ramifications
due to the fact that skb->priority still reflects
the mesh forwarded packet's ingress (correct) TID.
The mt7915 driver inspects the TID recorded within
skb->priority and relays this to the
hardware/radio during TX. The radio firmware appears to
react to this by changing the sequence control
header, but it does not also ensure/correct the TID in
the QoS control header. As a result, the receiver
will see packets with sequence numbers corresponding
to the wrong TID. The receiver of the forwarded
packet will see TID 0 in QoS control but a sequence number
corresponding to the correct (different) TID in sequence
control. This causes data stalls for TID 0 until
the TID 0 sequence number advances past what the receiver
believes it should be due to this bug.
Mesh routing mpath changes cause a brief transition
from fast path forwarding to slow path forwarding.
Since this bug only affects the slow path forwarding,
mpath changes bring opportunity for the bug to be triggered.
In the author's case, he was experiencing TID 0 data stalls
after mpath changes on an intermediate mesh node.
These observed stalls may be specific
to mediatek radios. But the inconsistency between
the packet header and skb->priority may cause problems
for other drivers as well. Regardless if this causes
connectivity issues on other radios, this change is
necessary in order transmit (forward) the packet on the
correct TID and to have a consistent view a packet's TID
within mac80211.

commit c4f075582304 ("wifi: mt76: mt7915: fix command timeout in AP stop

when enable_beacon becomes false: it calls mt7915_mcu_add_bss_info(...,
false) and mt7915_mcu_add_sta(..., false) while the previous code
didn't. These sends mcu commands that apparently confuse the firmware.
This breaks scanning while in mesh mode on AsiaRF MT7916 DBDC-based cards:
scanning works but no mesh frames get sent afterwards and the firmware
seems to be hosed. It breaks on MT7916 DBDC but not on MT7915 DBDC.

It is possible for multiple, simultaneous callers calling
device_node_get_regmap() with the same node to fail to find an entry in

calling of_syscon_register() that subsequent callers also fail to find
an entry in the syscon_list and then call of_syscon_register() a second
time.
Fix this by keeping the lock held until after of_syscon_register()
completes and adds the node to syscon_list. Convert the spinlock to a
mutex as many of the functions called in of_syscon_register() such as
kzalloc() and of_clk_get() may sleep.

mfd: syscon: Add of_syscon_register_regmap() API
[ Upstream commit 769cb63166d90f1fadafa4352f180cbd96b6cb77 ]
The of_syscon_register_regmap() API allows an externally created regmap
to be registered with syscon. This regmap can then be returned to client
drivers using the syscon_regmap_lookup_by_phandle() APIs.
The API is used by platforms where mmio access to the syscon registers is
not possible, and a underlying soc driver like exynos-pmu provides a SoC
specific regmap that can issue a SMC or hypervisor call to write the
register.
This approach keeps the SoC complexities out of syscon, but allows common
drivers such as syscon-poweroff, syscon-reboot and friends that are used
by many SoCs already to be re-used.

clk: qcom: gcc-sdm845: Do not use shared clk_ops for QUPs
[ Upstream commit f760a4bb5e927a133dcd75f7b69ccae2a331e42c ]
Similar to the earlier fixes meant for sm8x50 and x1e platforms,
we have to stop using the shared clk ops for sdm845 QUPs as well.
As Stephen Boyd pointed out in earlier fixes, there wasn't a problem
to mark QUP clks shared until we started parking shared RCGs at clk
registration time in commit 01a0a6cc8cfd ("clk: qcom: Park shared RCGs
upon registration"). Parking at init is actually harmful to the UART
when earlycon is used. If the device is pumping out data while the
frequency changes and we see garbage on the serial console until the
driver can probe and actually set a proper frequency.
This patch reverts the QUP clk sharing ops part of commit 06391eddb60a
("clk: qcom: Add Global Clock controller (GCC) driver for SDM845"), so
that the QUPs on sdm845 don't get parked during clk registration and
break UART operations.

wifi: ath12k: fix tx power, max reg power update to firmware
[ Upstream commit 3540bba855b4b422e8b977d11aa8173ccb4f089d ]
Currently, when the vdev start WMI cmd is sent from host, vdev related
parameters such as max_reg_power, max_power, and max_antenna_gain are
multiplied by 2 before being sent to the firmware. This is incorrect
because the firmware uses 1 dBm steps for power calculations.
This leads to incorrect power values being used in the firmware and
radio, potentially causing incorrect behavior.
Fix the update of max_reg_power, max_power, and max_antenna_gain values
in the ath12k_mac_vdev_start_restart function, ensuring accurate
power settings in the firmware by sending these values as-is,
without multiplication.

of_regulator_match() does not release the OF node reference in the error
path, resulting in an OF node leak. Therefore, call of_node_put() on the

Since it is possible that some drivers call this function and do not
exit on failure, such as s2mps11_pmic_driver, clear the init_data and
of_node in the error path.
This was reported by an experimental verification tool that I am
developing. As I do not have access to actual devices nor the QEMU board
configuration to test drivers that call this function, no runtime test
was able to be performed.

clk: sunxi-ng: a64: stop force-selecting PLL-MIPI as TCON0 parent
[ Upstream commit 383ca7bee8a93be9ff5a072936981c2710d2856b ]
Stop force-selecting PLL-MIPI as TCON0 parent, since it breaks video
output on Pinebook that uses RGB to eDP bridge.
Partially revert commit ca1170b69968 ("clk: sunxi-ng: a64: force
select PLL_MIPI in TCON0 mux"), while still leaving
CLK_SET_RATE_NO_REPARENT flag set, since we do not want the clock to
be reparented.
The issue is that apparently different TCON0 outputs require a different
clock, or the mux might be selecting the output type.
I did an experiment: I manually configured PLL_MIPI and PLL_VIDEO0_2X
to the same clock rate and flipped the switch with devmem. Experiment
clearly showed that whenever PLL_MIPI is selected as TCON0 clock parent,
the video output stops working.
Therefore, TCON0 clock parent corresponding to the output type must be
assigned in the device tree.

team: prevent adding a device which is already a team device lower
[ Upstream commit 3fff5da4ca2164bb4d0f1e6cd33f6eb8a0e73e50 ]
Prevent adding a device which is already a team device lower,
e.g. adding veth0 if vlan1 was already added and veth0 is a lower of
vlan1.
This is not useful in practice and can lead to recursive locking:
$ ip link add veth0 type veth peer name veth1
$ ip link set veth0 up
$ ip link set veth1 up
$ ip link add link veth0 name veth0.1 type vlan protocol 802.1Q id 1
$ ip link add team0 type team
$ ip link set veth0.1 down
$ ip link set veth0.1 master team0
team0: Port device veth0.1 added
$ ip link set veth0 down
$ ip link set veth0 master team0

The CLKOUTn may be fed from PLL1/2/3, but the PLL1/2/3 has to be enabled
first by setting PLL_CLKE bit 11 in CCM_ANALOG_SYS_PLLn_GEN_CTRL register.
The CCM_ANALOG_SYS_PLLn_GEN_CTRL bit 11 is modeled by plln_out clock. Fix
the clock tree and place the clkout1/2 under plln_sel instead of plain plln
to let the clock subsystem correctly control the bit 11 and enable the PLL
in case the CLKOUTn is supplied by PLL1/2/3.

cpufreq: qcom: Implement clk_ops::determine_rate() for qcom_cpufreq* clocks
[ Upstream commit a9ba290d0b829012574b6821ba08815046e60c94 ]
determine_rate() callback is used by the clk_set_rate() API to get the
closest rate of the target rate supported by the clock. If this callback
is not implemented (nor round_rate() callback), then the API will assume
that the clock cannot set the requested rate. And since there is no parent,
it will return -EINVAL.
This is not an issue right now as clk_set_rate() mistakenly compares the
target rate with cached rate and bails out early. But once that is fixed
to compare the target rate with the actual rate of the clock (returned by
recalc_rate()), then clk_set_rate() for this clock will start to fail as
below:
cpu cpu0: _opp_config_clk_single: failed to set clock rate: -22
So implement the determine_rate() callback that just returns the actual
rate at which the clock is passed to the CPUs in a domain.

cpufreq: qcom: Fix qcom_cpufreq_hw_recalc_rate() to query LUT if LMh IRQ is not available
[ Upstream commit 85d8b11351a8f15d6ec7a5e97909861cb3b6bcec ]
Currently, qcom_cpufreq_hw_recalc_rate() returns the LMh throttled
frequency for the domain even if LMh IRQ is not available. But as per
qcom_cpufreq_hw_get(), the driver has to query LUT entries to get the
actual frequency of the domain. So do the same in
qcom_cpufreq_hw_recalc_rate().
While doing so, refactor the existing qcom_cpufreq_hw_get() function so
that qcom_cpufreq_hw_recalc_rate() can make use of the existing code and
avoid code duplication. This also requires setting the
qcom_cpufreq_data::policy even if LMh IRQ is not available.

cpufreq: schedutil: Fix superfluous updates caused by need_freq_update
[ Upstream commit 8e461a1cb43d69d2fc8a97e61916dce571e6bb31 ]
A redundant frequency update is only truly needed when there is a policy
limits change with a driver that specifies CPUFREQ_NEED_UPDATE_LIMITS.
In spite of that, drivers specifying CPUFREQ_NEED_UPDATE_LIMITS receive a
frequency update _all the time_, not just for a policy limits change,
because need_freq_update is never cleared.
Furthermore, ignore_dl_rate_limit()'s usage of need_freq_update also leads
to a redundant frequency update, regardless of whether or not the driver
specifies CPUFREQ_NEED_UPDATE_LIMITS, when the next chosen frequency is the
same as the current one.
Fix the superfluous updates by only honoring CPUFREQ_NEED_UPDATE_LIMITS
when there's a policy limits change, and clearing need_freq_update when a
requisite redundant update occurs.
This is neatly achieved by moving up the CPUFREQ_NEED_UPDATE_LIMITS test
and instead setting need_freq_update to false in sugov_update_next_freq().

Deinitialize at reverse order when probe fails.
When init_sw_vars fails, rtl_deinit_core should not be called, specially
now that it destroys the rtl_wq workqueue.
And call rtl_pci_deinit and deinit_sw_vars, otherwise, memory will be
leaked.
Remove pci_set_drvdata call as it will already be cleaned up by the core
driver code and could lead to memory leaks too. cf. commit 8d450935ae7f

wifi: rtlwifi: destroy workqueue at rtl_deinit_core
[ Upstream commit d8ece6fc3694657e4886191b32ca1690af11adda ]
rtl_wq is allocated at rtl_init_core, so it makes more sense to destroy it
at rtl_deinit_core. In the case of USB, where _rtl_usb_init does not
require anything to be undone, that is fine. But for PCI, rtl_pci_init,
which is called after rtl_init_core, needs to deallocate data, but only if
it has been called.
That means that destroying the workqueue needs to be done whether
rtl_pci_init has been called or not. And since rtl_pci_deinit was doing it,
it has to be moved out of there.
It makes more sense to move it to rtl_deinit_core and have it done in both
cases, USB and PCI.
Since this is a requirement for a followup memory leak fix, mark this as
fixing such memory leak.

Commit 2461c7d60f9f ("rtlwifi: Update header file") introduced a global
list of private data structures.
Later on, commit 26634c4b1868 ("rtlwifi Modify existing bits to match
vendor version 2013.02.07") started adding the private data to that list at
probe time and added a hook, check_buddy_priv to find the private data from
a similar device.
However, that function was never used.
Besides, though there is a lock for that list, it is never used. And when
the probe fails, the private data is never removed from the list. This
would cause a second probe to access freed memory.
Remove the unused hook, structures and members, which will prevent the
potential race condition on the list and its corruption during a second
probe when probe fails.

of: remove internal arguments from of_property_for_each_u32()
[ Upstream commit 9722c3b66e21ff08aec570d02a97d331087fd70f ]
The of_property_for_each_u32() macro needs five parameters, two of which
are primarily meant as internal variables for the macro itself (in the
for() clause). Yet these two parameters are used by a few drivers, and this
can be considered misuse or at least bad practice.
Now that the kernel uses C11 to build, these two parameters can be avoided
by declaring them internally, thus changing this pattern:
struct property *prop;
const __be32 *p;
u32 val;
of_property_for_each_u32(np, "xyz", prop, p, val) { ... }
to this:
u32 val;
of_property_for_each_u32(np, "xyz", val) { ... }
However two variables cannot be declared in the for clause even with C11,
so declare one struct that contain the two variables we actually need. As
the variables inside this struct are not meant to be used by users of this
macro, give the struct instance the noticeable name "_it" so it is visible
during code reviews, helping to avoid new code to use it directly.
Most usages are trivially converted as they do not use those two
parameters, as expected. The non-trivial cases are:
- drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway
- drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the
checks had to be replicated in a different way, making code more verbose
and somewhat uglier, but I refrained from a full rework to keep as much
of the original code untouched having no hardware to test my changes
All the changes have been build tested. The few for which I have the
hardware have been runtime-tested too.

clk: si5351: allow PLLs to be adjusted without reset
[ Upstream commit b2adbc9cea752539f6421e9d4642408f666c1251 ]
Introduce a new PLL reset mode flag which controls whether or not to
reset a PLL after adjusting its rate. The mode can be configured through
platform data or device tree.
Since commit 6dc669a22c77 ("clk: si5351: Add PLL soft reset"), the
driver unconditionally resets a PLL whenever its rate is adjusted.
The rationale was that a PLL reset was required to get three outputs
working at the same time. Before this change, the driver never reset the
PLLs.
Commit b26ff127c52c ("clk: si5351: Apply PLL soft reset before enabling
the outputs") subsequently introduced an option to reset the PLL when
enabling a clock output that sourced it. Here, the rationale was that
this is required to get a deterministic phase relationship between
multiple output clocks.
This clearly shows that it is useful to reset the PLLs in applications
where multiple clock outputs are used. However, the Si5351 also allows
for glitch-free rate adjustment of its PLLs if one avoids resetting the
PLL. In our audio application where a single Si5351 clock output is used
to supply a runtime adjustable bit clock, this unconditional PLL reset
behaviour introduces unwanted glitches in the clock output.
It would appear that the problem being solved in the former commit
may be solved by using the optional device tree property introduced in
the latter commit, obviating the need for an unconditional PLL reset
after rate adjustment. But it's not OK to break the default behaviour of
the driver, and it cannot be assumed that all device trees are using the
property introduced in the latter commit. Hence, the new behaviour is
made opt-in.

woken up to go and process their termination, and as no further input is
forthcoming, they just hang.

The crash can be also be reproduced with the following (with a tc
recompiled to allow for sfq limits of 1):
tc qdisc add dev dummy0 handle 1: root tbf rate 1Kbit burst 100b lat 1s
../iproute2-6.9.0/tc/tc qdisc add dev dummy0 handle 2: parent 1:10 sfq limit 1
ifconfig dummy0 up
ping -I dummy0 -f -c2 -W0.1 8.8.8.8
sleep 1
Scenario that triggers the crash:
* the first packet is sent and queued in TBF and SFQ; qdisc qlen is 1
* TBF dequeues: it peeks from SFQ which moves the packet to the
gso_skb list and keeps qdisc qlen set to 1. TBF is out of tokens so
it schedules itself for later.
* the second packet is sent and TBF tries to queues it to SFQ. qdisc
qlen is now 2 and because the SFQ limit is 1 the packet is dropped
by SFQ. At this point qlen is 1, and all of the SFQ slots are empty,
however q->tail is not NULL.
At this point, assuming no more packets are queued, when sch_dequeue
runs again it will decrement the qlen for the current empty slot
causing an underflow and the subsequent out of bounds access.

net_sched: sch_sfq: handle bigger packets
[ Upstream commit e4650d7ae4252f67e997a632adfae0dd74d3a99a ]
SFQ has an assumption on dealing with packets smaller than 64KB.
Even before BIG TCP, TCA_STAB can provide arbitrary big values
in qdisc_pkt_len(skb)
It is time to switch (struct sfq_slot)->allot to a 32bit field.
sizeof(struct sfq_slot) is now 64 bytes, giving better cache locality.

wifi: ath11k: Fix unexpected return buffer manager error for WCN6750/WCN6855
[ Upstream commit 78e154d42f2c72905fe66a400847e1b2b101b7b2 ]
The following error messages were encountered while parsing fragmented RX
packets for WCN6750/WCN6855:
ath11k 17a10040.wifi: invalid return buffer manager 4
This issue arose due to a hardcoded check for HAL_RX_BUF_RBM_SW3_BM
introduced in 'commit 71c748b5e01e ("ath11k: Fix unexpected return buffer
manager error for QCA6390")'
For WCN6750 and WCN6855, the return buffer manager ID should be
HAL_RX_BUF_RBM_SW1_BM. The incorrect conditional check caused fragmented
packets to be dropped, resulting in the above error log.
Fix this by adding a check for HAL_RX_BUF_RBM_SW1_BM.

OPP: fix dev_pm_opp_find_bw_*() when bandwidth table not initialized

If a driver calls dev_pm_opp_find_bw_ceil/floor() the retrieve bandwidth
from the OPP table but the bandwidth table was not created because the
interconnect properties were missing in the OPP consumer node, the

HID: core: Fix assumption that Resolution Multipliers must be in Logical Collections
commit 64f2657b579343cf923aa933f08074e6258eb07b upstream.
A report in 2019 by the syzbot fuzzer was found to be connected to two
errors in the HID core associated with Resolution Multipliers. One of
the errors was fixed by commit ea427a222d8b ("HID: core: Fix deadloop
in hid_apply_multiplier."), but the other has not been fixed.
This error arises because hid_apply_multipler() assumes that every
Resolution Multiplier control is contained in a Logical Collection,
i.e., there's no way the routine can ever set multiplier_collection to
NULL. This is in spite of the fact that the function starts with a
big comment saying:
* "The Resolution Multiplier control must be contained in the same
* Logical Collection as the control(s) to which it is to be applied.
...
* If no Logical Collection is
* defined, the Resolution Multiplier is associated with all
* controls in the report."
* HID Usage Table, v1.12, Section 4.3.1, p30
*
* Thus, search from the current collection upwards until we find a
* logical collection...
The comment and the code overlook the possibility that none of the
collections found may be a Logical Collection.
The fix is to set the multiplier_collection pointer to NULL if the
collection found isn't a Logical Collection.

x86/topology: Use x86_sched_itmt_flags for PKG domain unconditionally
[ Upstream commit e1bc02646527fc1ed74f00eb599b2b74d49671c7 ]
x86_sched_itmt_flags() returns SD_ASYM_PACKING if ITMT support is
enabled by the system. Without ITMT support being enabled, it returns 0
similar to current x86_die_flags() on non-Hybrid systems
(!X86_HYBRID_CPU and !X86_FEATURE_AMD_HETEROGENEOUS_CORES)
On Intel systems that enable ITMT support, either the MC domain
coincides with the PKG domain, or in case of multiple MC groups
within a PKG domain, either Sub-NUMA Cluster (SNC) is enabled or the
processor features Hybrid core layout (X86_HYBRID_CPU) which leads to
three distinct possibilities:
o If PKG and MC domains coincide, PKG domain is degenerated by
sd_parent_degenerate() when building sched domain topology.
o If SNC is enabled, PKG domain is never added since
"x86_has_numa_in_package" is set and the topology will instead contain
NODE and NUMA domains.
o On X86_HYBRID_CPU which contains multiple MC groups within the PKG,
the PKG domain requires x86_sched_itmt_flags().
Thus, on Intel systems that contains multiple MC groups within the PKG
and enables ITMT support, the PKG domain requires
x86_sched_itmt_flags(). In all other cases PKG domain is either never
added or is degenerated. Thus, returning x86_sched_itmt_flags()
unconditionally at PKG domain on Intel systems should not lead to any
functional changes.
On AMD systems with multiple LLCs (MC groups) within a PKG domain,
enabling ITMT support requires setting SD_ASYM_PACKING to the PKG domain
since the core rankings are assigned PKG-wide.
Core rankings on AMD processors is currently set by the amd-pstate
driver when Preferred Core feature is supported. A subset of systems that
support Preferred Core feature can be detected using
X86_FEATURE_AMD_HETEROGENEOUS_CORES however, this does not cover all the
systems that support Preferred Core ranking.
Detecting Preferred Core support on AMD systems requires inspecting CPPC
Highest Perf on all present CPUs and checking if it differs on at least
one CPU. Previous suggestion to use a synthetic feature to detect
Preferred Core support [1] was found to be non-trivial to implement
since BSP alone cannot detect if Preferred Core is supported and by the
time AP comes up, alternatives are patched and setting a X86_FEATURE_*
then is not possible.
Since x86 processors enabling ITMT support that consists multiple
non-NUMA MC groups within a PKG requires SD_ASYM_PACKING flag set at the
PKG domain, return x86_sched_itmt_flags unconditionally for the PKG
domain.
Since x86_die_flags() would have just returned x86_sched_itmt_flags()
after the change, remove the unnecessary wrapper and pass
x86_sched_itmt_flags() directly as the flags function.

Enable the SD_ASYM_PACKING domain flag for the PKG domain on AMD heterogeneous
processors. This flag is beneficial for processors with one or more CCDs and
relies on x86_sched_itmt_flags().

sched/fair: Fix value reported by hot tasks pulled in /proc/schedstat
[ Upstream commit a430d99e349026d53e2557b7b22bd2ebd61fe12a ]
In /proc/schedstat, lb_hot_gained reports the number hot tasks pulled
during load balance. This value is incremented in can_migrate_task()
if the task is migratable and hot. After incrementing the value,
load balancer can still decide not to migrate this task leading to wrong
accounting. Fix this by incrementing stats when hot tasks are detached.
This issue only exists in detach_tasks() where we can decide to not
migrate hot task even if it is migratable. However, in detach_one_task(),
we migrate it unconditionally.

perf/core: Save raw sample data conditionally based on sample type
[ Upstream commit b9c44b91476b67327a521568a854babecc4070ab ]
Currently, space for raw sample data is always allocated within sample
records for both BPF output and tracepoint events. This leads to unused
space in sample records when raw sample data is not requested.
This patch enforces checking sample type of an event in
perf_sample_save_raw_data(). So raw sample data will only be saved if
explicitly requested, reducing overhead when it is not needed.

On powerpc/32s, user_read_access_begin/end() are no-ops, but the
failure path has a user_access_end() instead of user_read_access_end()
which means an access end without any prior access begin.

nbd: don't allow reconnect after disconnect

2) nbd_genl_disconnect() flush all recv_work() and release the
initial reference:
nbd_genl_disconnect
nbd_disconnect_and_put
nbd_disconnect
flush_workqueue(nbd->recv_workq)
if (test_and_clear_bit(NBD_RT_HAS_CONFIG_REF, ...))
nbd_config_put
-> due to step 1), reference is still not zero
3) nbd_genl_reconfigure() queue recv_work() again;
nbd_genl_reconfigure
config = nbd_get_config_unlocked(nbd)
if (!config)
-> succeed
if (!test_bit(NBD_RT_BOUND, ...))
-> succeed
nbd_reconnect_socket
queue_work(nbd->recv_workq, &args->work)
4) step 1) release the reference;
5) Finially, recv_work() will trigger UAF:
recv_work
nbd_config_put(nbd)
-> nbd_config is freed
atomic_dec(&config->recv_threads)
-> UAF
Fix the problem by clearing NBD_RT_BOUND in nbd_genl_disconnect(), so

and then the retry will call loop_probe to prepare the loop disk. Finally
open for this disk will success. However, after this commit, we lose the
retry logic, and open will fail with ENXIO. Block device autoloading is
deprecated and will be removed soon, but maybe we should keep open success
until we really remove it. So, give a retry to fix it.

afs: Fix cleanup of immediately failed async calls
[ Upstream commit 9750be93b2be12b6d92323b97d7c055099d279e6 ]
If we manage to begin an async call, but fail to transmit any data on it
due to a signal, we then abort it which causes a race between the
notification of call completion from rxrpc and our attempt to cancel the
notification. The notification will be necessary, however, for async
FetchData to terminate the netfs subrequest.
However, since we get a notification from rxrpc upon completion of a call
(aborted or otherwise), we can just leave it to that.
This leads to calls not getting cleaned up, but appearing in
/proc/net/rxrpc/calls as being aborted with code 6.
Fix this by making the "error_do_abort:" case of afs_make_call() abort the
call and then abandon it to the notification handler.

many alloc counter slots declared and so pushes the hash table along and
over the data. This doesn't cause a problem at the moment because I'm
currently ignoring the hash table and only using the correct number of
alloc_ctrs in the code anyway. In future, however, I should start using
the hash table to try and speed up afs_lookup().

powerpc/book3s64/hugetlb: Fix disabling hugetlb when fadump is active
[ Upstream commit d629d7a8efc33d05d62f4805c0ffb44727e3d99f ]
Commit 8597538712eb ("powerpc/fadump: Do not use hugepages when fadump
is active") disabled hugetlb support when fadump is active by returning
early from hugetlbpage_init():arch/powerpc/mm/hugetlbpage.c and not
populating hpage_shift/HPAGE_SHIFT.
Later, commit 2354ad252b66 ("powerpc/mm: Update default hugetlb size
early") moved the allocation of hpage_shift/HPAGE_SHIFT to early boot,
which inadvertently re-enabled hugetlb support when fadump is active.
Fix this by implementing hugepages_supported() on powerpc. This ensures
that disabling hugetlb for the fadump kernel is independent of
hpage_shift/HPAGE_SHIFT.
