b3172ec3ab PCI: endpoint: pci-epf-test: Fix doorbell test support
[ Upstream commit f272210b28 ]

The doorbell feature temporarily overrides the inbound translation to point
to the address stored in epf_test->db_bar.phys_addr, i.e., it calls
set_bar() twice without ever calling clear_bar(), as calling clear_bar()
would clear the BAR's PCI address assigned by the host.

Thus, when disabling the doorbell, restore the inbound translation to point
to the memory allocated for the BAR.

Without this, running the PCI endpoint kselftest doorbell test case more
than once would fail.

ad09d55b52 watchdog: mpc8xxx_wdt: Reload the watchdog timer when enabling the watchdog
[ Upstream commit 7dfd80f70e ]

When the watchdog gets enabled with this driver, it leaves enough time
for the core watchdog subsystem to start pinging it. But when the
watchdog is already started by hardware or by the boot loader, little
time remains before it fires and it happens that the core watchdog
subsystem doesn't have time to start pinging it.

Until commit 19ce9490aa ("watchdog: mpc8xxx: use the core worker
function") pinging was managed by the driver itself and the watchdog
was immediately pinged by setting the timer expiry to 0.

So restore similar behaviour by pinging it when enabling it so that
if it was already enabled the watchdog timer counter is reloaded.

ffaf14cd80 ipvs: Use READ_ONCE/WRITE_ONCE for ipvs->enable
[ Upstream commit 944b6b216c ]

KCSAN reported a data-race on the `ipvs->enable` flag, which is
written in the control path and read concurrently from many other
contexts.

Following a suggestion by Julian, this patch fixes the race by
converting all accesses to use `WRITE_ONCE()/READ_ONCE()`.
This lightweight approach ensures atomic access and acts as a
compiler barrier, preventing unsafe optimizations where the flag
is checked in loops (e.g., in ip_vs_est.c).

Additionally, the `enable` checks in the fast-path hooks
(`ip_vs_in_hook`, `ip_vs_out_hook`, `ip_vs_forward_icmp`) are
removed. These are unnecessary since commit 857ca89711
("ipvs: register hooks only with services"). The `enable=0`
condition they check for can only occur in two rare and non-fatal
scenarios: 1) after hooks are registered but before the flag is set,
and 2) after hooks are unregistered on cleanup_net. In the worst
case, a single packet might be mishandled (e.g., dropped), which
does not lead to a system crash or data corruption. Adding a check
in the performance-critical fast-path to handle this harmless
condition is not a worthwhile trade-off.

5beca7388b RDMA/mlx5: Fix page size bitmap calculation for KSM mode
[ Upstream commit 372fdb5c75 ]

When using KSM (Key Scatter-gather Memory) access mode, the HW requires
the IOVA to be aligned to the selected page size.
Without this alignment, the HW may not function correctly.

Currently, mlx5_umem_mkc_find_best_pgsz() does not filter out page sizes
that would result in misaligned IOVAs for KSM mode. This can lead to
selecting page sizes that are incompatible with the given IOVA.

Fix this by filtering the page size bitmap when in KSM mode, keeping
only page sizes to which the IOVA is aligned to.

cc93a995e4 mm/slub: Fix cmp_loc_by_count() to return 0 when counts are equal
[ Upstream commit e1c4350327 ]

The comparison function cmp_loc_by_count() used for sorting stack trace
locations in debugfs currently returns -1 if a->count > b->count and 1
otherwise. This breaks the antisymmetry property required by sort(),
because when two counts are equal, both cmp(a, b) and cmp(b, a) return
1.

This can lead to undefined or incorrect ordering results. Fix it by
updating the comparison logic to explicitly handle the case when counts
are equal, and use cmp_int() to ensure the comparison function adheres
to the required mathematical properties of antisymmetry.

80e3155181 iio: consumers: Fix handling of negative channel scale in iio_convert_raw_to_processed()
[ Upstream commit 0f85406bf8 ]

There is an issue with the handling of negative channel scales
in iio_convert_raw_to_processed_unlocked() when the channel-scale
is of the IIO_VAL_INT_PLUS_[MICRO|NANO] type:

Things work for channel-scale values > -1.0 and < 0.0 because of
the use of signed values in:

	*processed += div_s64(raw64 * (s64)scale_val2 * scale, 1000000LL);

Things will break however for scale values < -1.0. Lets for example say
that raw = 2, (caller-provided)scale = 10 and (channel)scale_val = -1.5.

The result should then be 2 * 10 * -1.5 = -30.

channel-scale = -1.5 means scale_val = -1 and scale_val2 = 500000,
now lets see what gets stored in processed:

1. *processed = raw64 * scale_val * scale;
2. *processed += raw64 * scale_val2 * scale / 1000000LL;

1. Sets processed to 2 * -1 * 10 = -20
2. Adds 2 * 500000 * 10 / 1000000 = 10 to processed

And the end result is processed = -20 + 10 = -10, which is not correct.

Fix this by always using the abs value of both scale_val and scale_val2
and if either is negative multiply the end-result by -1.

Note there seems to be an unwritten rule about negative
IIO_VAL_INT_PLUS_[MICRO|NANO] values that:

i.   values > -1.0 and < 0.0 are written as val=0 val2=-xxx
ii.  values <= -1.0 are written as val=-xxx val2=xxx

But iio_format_value() will also correctly display a third option:

iii. values <= -1.0 written as val=-xxx val2=-xxx

Since iio_format_value() uses abs(val) when val2 < 0.

This fix also makes iio_convert_raw_to_processed() properly handle
channel-scales using this third option.

039ddf353c fs/ntfs3: reject index allocation if $BITMAP is empty but blocks exist
[ Upstream commit 0dc7117da8 ]

Index allocation requires at least one bit in the $BITMAP attribute to
track usage of index entries. If the bitmap is empty while index blocks
are already present, this reflects on-disk corruption.

syzbot triggered this condition using a malformed NTFS image. During a
rename() operation involving a long filename (which spans multiple
index entries), the empty bitmap allowed the name to be added without
valid tracking. Subsequent deletion of the original entry failed with
-ENOENT, due to unexpected index state.

Reject such cases by verifying that the bitmap is not empty when index
blocks exist.

from MFT attributes (for example, $DATA), converting them into a runs_tree
structure, which describes the mapping of virtual clusters (VCN) to
logical clusters (LCN). The NTFS3 subsystem also has a shortcut for
deleting files from MFT records - in this case, the RUN_DEALLOCATE
command is sent to the run_unpack input, and the function logic
provides that all data transferred to the runlist about file or
directory is deleted without creating a runs_tree structure.

Substituting the runlist in the $DATA attribute of the MFT record for an
arbitrary file can lead either to access to arbitrary data on the disk
bypassing access checks to them (since the inode access check
occurs above) or to destruction of arbitrary data on the disk.

Add overflow check for addition operation.

394047c49d wifi: mac80211: fix reporting of all valid links in sta_set_sinfo()
[ Upstream commit eebccbfea4 ]

Currently, sta_set_sinfo() fails to populate link-level station info
when sinfo->valid_links is initially 0 and sta->sta.valid_links has
bits set for links other than link 0. This typically occurs when
association happens on a non-zero link or link 0 deleted dynamically.
In such cases, the for_each_valid_link(sinfo, link_id) loop only
executes for link 0 and terminates early, since sinfo->valid_links
remains 0. As a result, only MLD-level information is reported to
userspace.

Hence to fix, initialize sinfo->valid_links with sta->sta.valid_links
before entering the loop to ensure loop executes for each valid link.
During iteration, mask out invalid links from sinfo->valid_links if
any of sta->link[link_id], sdata->link[link_id], or sinfo->links[link_id]
are not present, to report only valid link information.

f981d155e0 idpf: fix Rx descriptor ready check barrier in splitq
[ Upstream commit c20edbacc0 ]

No idea what the current barrier position was meant for. At that point,
nothing is read from the descriptor, only the pointer to the actual one
is fetched.
The correct barrier usage here is after the generation check, so that
only the first qword is read if the descriptor is not yet ready and we
need to stop polling. Debatable on coherent DMA as the Rx descriptor
size is <= cacheline size, but anyway, the current barrier position
only makes the codegen worse.

Before commit c79a39dc8d ("pps: Fix a use-after-free"),
pps_register_cdev() call device_create() to create pps->dev, which will
init dev->release to device_create_release(). Now the comment is outdated,
just remove it.

Thanks for the reminder from Calvin Owens, 'kfree_pps' should be removed
in pps_register_source() to avoid a double free in the failure case.

c5a2791a7f tty: n_gsm: Don't block input queue by waiting MSC
[ Upstream commit 3cf0b3c243 ]

Currently gsm_queue() processes incoming frames and when opening
a DLC channel it calls gsm_dlci_open() which calls gsm_modem_update().
If basic mode is used it calls gsm_modem_upd_via_msc() and it
cannot block the input queue by waiting the response to come
into the same input queue.

Instead allow sending Modem Status Command without waiting for remote
end to respond. Define a new function gsm_modem_send_initial_msc()
for this purpose. As MSC is only valid for basic encoding, it does
not do anything for advanced or when convergence layer type 2 is used.

bd72b648bd usb: gadget: configfs: Correctly set use_os_string at bind
[ Upstream commit e271cc0d25 ]

Once the use_os_string flag is set to true for some functions
(e.g. adb/mtp) which need to response the OS string, and then
if we re-bind the ConfigFS gadget to use the other functions
(e.g. hid) which should not to response the OS string, however,
because the use_os_string flag is still true, so the usb gadget
response the OS string descriptor incorrectly, this can cause
the USB device to be unrecognizable on the Windows system.

An example of this as follows:

echo 1 > os_desc/use
ln -s functions/ffs.adb configs/b.1/function0
start adbd
echo "<udc device>" > UDC   #succeed

stop adbd
rm configs/b.1/function0
echo 0 > os_desc/use
ln -s functions/hid.gs0 configs/b.1/function0
echo "<udc device>" > UDC  #fail to connect on Windows

This patch sets the use_os_string flag to false at bind if
the functions not support OS Descriptors.

73ce2a774a fanotify: Validate the return value of mnt_ns_from_dentry() before dereferencing
[ Upstream commit 62e59ffe87 ]

The function do_fanotify_mark() does not validate if
mnt_ns_from_dentry() returns NULL before dereferencing mntns->user_ns.
This causes a NULL pointer dereference in do_fanotify_mark() if the
path is not a mount namespace object.

Fix this by checking mnt_ns_from_dentry()'s return value before
dereferencing it.

Before the patch

$ gcc fanotify_nullptr.c -o fanotify_nullptr
$ mkdir A
$ ./fanotify_nullptr
Fanotify fd: 3
fanotify_mark: Operation not permitted
$ unshare -Urm
Fanotify fd: 3
Killed

int main(void){
    int ffd;
    ffd = fanotify_init(FAN_CLASS_NOTIF | FAN_REPORT_MNT, 0);
    if(ffd < 0){
        perror("fanotify_init");
        exit(EXIT_FAILURE);
    }

    printf("Fanotify fd: %d\n",ffd);

    if(fanotify_mark(ffd, FAN_MARK_ADD | FAN_MARK_MNTNS,
FAN_MNT_ATTACH, AT_FDCWD, "A") < 0){
        perror("fanotify_mark");
        exit(EXIT_FAILURE);
    }

return 0;
}

After the patch

$ gcc fanotify_nullptr.c -o fanotify_nullptr
$ mkdir A
$ ./fanotify_nullptr
Fanotify fd: 3
fanotify_mark: Operation not permitted
$ unshare -Urm
Fanotify fd: 3

e4ed50b0dc PCI: qcom: Add equalization settings for 8.0 GT/s and 32.0 GT/s
[ Upstream commit 37bf0f4e39 ]

Add lane equalization setting for 8.0 GT/s and 32.0 GT/s to enhance link
stability and avoid AER Correctable Errors reported on some platforms
(eg. SA8775P).

8.0 GT/s, 16.0 GT/s and 32.0 GT/s require the same equalization setting.
This setting is programmed into a group of shadow registers, which can be
switched to configure equalization for different speeds by writing 00b,
01b and 10b to `RATE_SHADOW_SEL`.

Hence, program equalization registers in a loop using link speed as index,
so that equalization setting can be programmed for 8.0 GT/s, 16.0 GT/s
and 32.0 GT/s.

db28bf40d3 wifi: mac80211: consider links for validating SCAN_FLAG_AP in scan request during MLO
[ Upstream commit 36b75dcb1e ]

Commit 78a7a126dc ("wifi: mac80211: validate SCAN_FLAG_AP in scan request
during MLO") introduced a check that rejects scan requests if any link is
already beaconing. This works fine when all links share the same radio, but
breaks down in multi-radio setups.

Consider a scenario where a 2.4 GHz link is beaconing and a scan is
requested on a 5 GHz link, each backed by a different physical radio. The
current logic still blocks the scan, even though it should be allowed. As a
result, interface bring-up fails unnecessarily in valid configurations.

Fix this by checking whether the scan is being requested on the same
underlying radio as the beaconing link. Only reject the scan if it targets
a link that is already beaconing and the NL80211_FEATURE_AP_SCAN is not
set. This ensures correct behavior in multi-radio environments and avoids
false rejections.
