When encountering a string bigger than the destination buffer (32 bytes),
the string is not properly NUL-terminated, causing buffer overreads later.
This for example happens on the Inspiron 3505, where the battery
model name is larger than 32 bytes, which leads to sysfs showing
the model name together with the serial number string (which is
NUL-terminated and thus prevents worse).
Fix this by using strscpy() which ensures that the result is
always NUL-terminated.

Syzkaller detected a memory leak of skbs in ath9k_hif_usb_rx_stream().
While processing skbs in ath9k_hif_usb_rx_stream(), the already allocated
skbs in skb_pool are not freed if ath9k_hif_usb_rx_stream() fails. If we
have an incorrect pkt_len or pkt_tag, the input skb is considered invalid
and dropped. All the associated packets already in skb_pool should be
dropped and freed. Added a comment describing this issue.
The patch also makes remain_skb NULL after being processed so that it
cannot be referenced after potential free. The initialization of hif_dev
fields which are associated with remain_skb (rx_remain_len,
rx_transfer_len and rx_pad_len) is moved after a new remain_skb is
allocated.

[ Upstream commit
b39f662ce1648db0b9de32e6a849b098480793cb ]
The wifi + bluetooth combo chip RTL8723BU can leak memory (especially?)
when it's connected to a bluetooth audio device. The busy bluetooth
traffic generates lots of C2H (card to host) messages, which are not
freed correctly.
To fix this, move the dev_kfree_skb() call in rtl8xxxu_c2hcmd_callback()
inside the loop where skb_dequeue() is called.
The RTL8192EU leaks memory because the C2H messages are added to the
queue and left there forever. (This was fine in the past because it
probably wasn't sending any C2H messages until commit
e542e66b7c2e
("wifi: rtl8xxxu: gen2: Turn on the rate control"). Since that commit
it sends a C2H message when the TX rate changes.)
To fix this, delete the check for rf_paths > 1 and the goto. Let the
function process the C2H messages from RTL8192EU like the ones from
the other chips.
Theoretically the RTL8188FU could also leak like RTL8723BU, but it
most likely doesn't send C2H messages frequently enough.
This change was tested with RTL8723BU by Erhard F. I tested it with
RTL8188FU and RTL8192EU.

thermal/drivers/tsens: limit num_sensors to 9 for msm8939
[ Upstream commit
903238a33c116edf5f64f7a3fd246e6169cccfa6 ]
On msm8939 last (hwid=10) sensor was added in the hw revision 3.0.
Calibration data for it was placed outside of the main calibration data
blob, so it is not accessible by the current blob-parsing code.
Moreover data for the sensor's p2 is not contiguous in the fuses. This
makes it hard to use nvmem_cell API to parse calibration data in a
generic way.
Since the sensor doesn't seem to be actually used by the existing
hardware, disable the sensor for now.

Tsens driver mentions that msm8976 data should be used for both msm8976

vendor kernels, msm8976 should use standard slope values (3200), while
msm8956 really uses the slope values found in the driver.
Add separate compatibility string for msm8956, move slope value

x86/signal: Fix the value returned by strict_sas_size()
[ Upstream commit
ef6dfc4b238a435ab552207ec09e4a82b6426d31 ]
Functions used with __setup() return 1 when the argument has been
successfully parsed.
Reverse the returned value so that 1 is returned when kstrtobool() is
successful (i.e. returns 0).
My understanding of these __setup() functions is that returning 1 or 0
does not change much anyway - so this is more of a cleanup than a
functional fix.
I spot it and found it spurious while looking at something else.
Even if the output is not perfect, you'll get the idea with:

rcu-tasks: Fix synchronize_rcu_tasks() VS zap_pid_ns_processes()
[ Upstream commit
28319d6dc5e2ffefa452c2377dd0f71621b5bff0 ]
RCU Tasks and PID-namespace unshare can interact in do_exit() in a
complicated circular dependency:
1) TASK A calls unshare(CLONE_NEWPID), this creates a new PID namespace
that every subsequent child of TASK A will belong to. But TASK A
doesn't itself belong to that new PID namespace.
2) TASK A forks() and creates TASK B. TASK A stays attached to its PID
namespace (let's say PID_NS1) and TASK B is the first task belonging
to the new PID namespace created by unshare() (let's call it PID_NS2).
3) Since TASK B is the first task attached to PID_NS2, it becomes the
PID_NS2 child reaper.
4) TASK A forks() again and creates TASK C which get attached to PID_NS2.
Note how TASK C has TASK A as a parent (belonging to PID_NS1) but has
TASK B (belonging to PID_NS2) as a pid_namespace child_reaper.
5) TASK B exits and since it is the child reaper for PID_NS2, it has to
kill all other tasks attached to PID_NS2, and wait for all of them to
die before getting reaped itself (zap_pid_ns_process()).
6) TASK A calls synchronize_rcu_tasks() which leads to
synchronize_srcu(&tasks_rcu_exit_srcu).
7) TASK B is waiting for TASK C to get reaped. But TASK B is under a
tasks_rcu_exit_srcu SRCU critical section (exit_notify() is between
exit_tasks_rcu_start() and exit_tasks_rcu_finish()), blocking TASK A.
8) TASK C exits and since TASK A is its parent, it waits for it to reap
TASK C, but it can't because TASK A waits for TASK B that waits for
TASK C.
Pid_namespace semantics can hardly be changed at this point. But the
coverage of tasks_rcu_exit_srcu can be reduced instead.
The current task is assumed not to be concurrently reapable at this
stage of exit_notify() and therefore tasks_rcu_exit_srcu can be
temporarily relaxed without breaking its constraints, providing a way
out of the deadlock scenario.

long writes to 0x80. These writes aren't making it over because of this
blockage. The first 4 byte write attempt is rejected, and then
subsequently 1 byte at a time each offset is tried. The first at 0x80
works, but then the next 3 bytes are rejected.
This manifests in bizarre failures for devices that expected the AML to
write all 4 bytes. Trying the same AML on Windows 10 or 11 doesn't hit
this failure and all 4 bytes are written.
Either some of these regions were wrong or some point after Windows XP
some of these regions blocks have been lifted.
In the last 15 years there doesn't seem to be any reports popping up of
this error in the Windows event viewer anymore. There is no documentation
at Microsoft's developer site indicating that Windows ACPI interpreter
blocks these regions. Between the lack of documentation and the fact that
the writes actually do work in Windows 10 and 11, it's quite likely
Windows doesn't actually enforce this anymore.
So to help the issue, only enforce Windows XP specific entries if the
latest _OSI supported is Windows XP. Continue to enforce the
ALWAYS_ILLEGAL entries.

libbpf: Fix invalid return address register in s390
[ Upstream commit

There is currently an invalid register mapping in the s390 return
address register. As the manual[1] states, the return address can be
found at r14. In bpf_tracing.h, the s390 registers were named
gprs(general purpose registers). This commit fixes the problem by
correcting the mistyped mapping.

libbpf: Fix btf__align_of() by taking into account field offsets
[ Upstream commit
25a4481b4136af7794e1df2d6c90ed2f354d60ce ]
btf__align_of() is supposed to be return alignment requirement of
a requested BTF type. For STRUCT/UNION it doesn't always return correct
value, because it calculates alignment only based on field types. But
for packed structs this is not enough, we need to also check field
offsets and struct size. If field offset isn't aligned according to
field type's natural alignment, then struct must be packed. Similarly,
if struct size is not a multiple of struct's natural alignment, then
struct must be packed as well.
This patch fixes this issue precisely by additionally checking these
conditions.

The root cause of the problem is that the comparison order of
"prate_section" in _rtl8812ae_phy_set_txpower_limit() is wrong. The
_rtl8812ae_eq_n_byte() is used to compare the first n bytes of the two
strings from tail to head, which causes the problem. In the
_rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet
this requirement by carefully designing the comparison order.
For example, "pregulation" and "pbandwidth" are compared in order of
length from small to large, first is 3 and last is 4. However, the
comparison order of "prate_section" dose not obey such order requirement,
therefore when "prate_section" is "HT", when comparing from tail to head,
it will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As
mentioned above, the _rtl8812ae_eq_n_byte() has the same function as
strcmp(), so just strcmp() is enough.
Fix it by removing _rtl8812ae_eq_n_byte() and use strcmp() barely.
Although it can be fixed by adjusting the comparison order of
"prate_section", this may cause the value of "rate_section" to not be
from 0 to 5. In addition, commit "
21e4b0726dc6" not only moved driver
from staging to regular tree, but also added setting txpower limit
function during the driver config phase, so the problem was introduced
by this commit.

block: sync mixed merged request's failfast with 1st bio's
[ Upstream commit
3ce6a115980c019928fcd06e01f64003886af79c ]
We support mixed merge for requests/bios with different fastfail
settings. When request fails, each time we only handle the portion
with same failfast setting, then bios with failfast can be failed
immediately, and bios without failfast can be retried.
The idea is pretty good, but the current implementation has several
defects:
1) initially RA bio doesn't set failfast, however bio merge code
doesn't consider this point, and just check its failfast setting for
deciding if mixed merge is required. Fix this issue by adding helper
of bio_failfast().
2) when merging bio to request front, if this request is mixed
merged, we have to sync request's faifast setting with 1st bio's
failfast. Fix it by calling blk_update_mixed_merge().
3) when merging bio to request back, if this request is mixed
merged, we have to mark the bio as failfast, because blk_update_request
simply updates request failfast with 1st bio's failfast. Fix
it by calling blk_update_mixed_merge().
Fixes one normal EXT4 READ IO failure issue, because it is observed
that the normal READ IO is merged with RA IO, and the mixed merged
request has different failfast setting with 1st bio's, so finally
the normal READ IO doesn't get retried.

This is a excessive check. If UBLK_F_NEED_GET_DATA is

perf/x86/intel/ds: Fix the conversion from TSC to perf time
[ Upstream commit
89e97eb8cec0f1af5ebf2380308913256ca7915a ]
The time order is incorrect when the TSC in a PEBS record is used.
$perf record -e cycles:upp dd if=/dev/zero of=/dev/null
count=10000
$ perf script --show-task-events
perf-exec 0 0.000000: PERF_RECORD_COMM: perf-exec:915/915
dd 915 106.479872: PERF_RECORD_COMM exec: dd:915/915
dd 915 106.483270: PERF_RECORD_EXIT(915:915):(914:914)
dd 915 106.512429: 1 cycles:upp:
ffffffff96c011b7 [unknown] ([unknown])
... ...
The perf time is from sched_clock_cpu(). The current PEBS code
unconditionally convert the TSC to native_sched_clock(). There is a
shift between the two clocks. If the TSC is stable, the shift is
consistent, __sched_clock_offset. If the TSC is unstable, the shift has
to be calculated at runtime.
This patch doesn't support the conversion when the TSC is unstable. The
TSC unstable case is a corner case and very unlikely to happen. If it
happens, the TSC in a PEBS record will be dropped and fall back to
perf_event_clock().

Commit

removed any path which could make pick_next_rt_entity() return NULL.
However, BUG_ON(!rt_se) in _pick_next_task_rt() (the only caller of
pick_next_rt_entity()) still checks the error condition, which can
never happen, since list_entry() never returns NULL.
Remove the BUG_ON check, and instead emit a warning in the only

e5e961628d696237ddc3d53d9d5ac11f43e0bf67 ]
MT8186's watchdog embeds a reset controller and needs only the
mediatek,mt8186-wdt compatible string as the MT6589 one is there
for watchdogs that don't have any reset controller capability.
