8d0f1f6420 vt: prevent kernel-infoleak in con_font_get()
commit f956052e00de211b5c9ebaa1958366c23f82ee9e upstream.

font.data may not initialize all memory spaces depending on the implementation
of vc->vc_sw->con_font_get. This may cause info-leak, so to prevent this, it
is safest to modify it to initialize the allocated memory space to 0, and it
generally does not affect the overall performance of the system.

56c4cfaa0f drm/shmem-helper: Fix BUG_ON() on mmap(PROT_WRITE, MAP_PRIVATE)
commit 39bc27bd688066a63e56f7f64ad34fae03fbe3b8 upstream.

Lack of check for copy-on-write (COW) mapping in drm_gem_shmem_mmap
allows users to call mmap with PROT_WRITE and MAP_PRIVATE flag
causing a kernel panic due to BUG_ON in vmf_insert_pfn_prot:
BUG_ON((vma->vm_flags & VM_PFNMAP) && is_cow_mapping(vma->vm_flags));

Return -EINVAL early if COW mapping is detected.

This bug affects all drm drivers using default shmem helpers.
It can be reproduced by this simple example:
void *ptr = mmap(0, size, PROT_WRITE, MAP_PRIVATE, fd, mmap_offset);
ptr[0] = 0;

1a6bf429eb Revert "drm/mipi-dsi: Set the fwnode for mipi_dsi_device"
This reverts commit 139c27648f8d3b2283f74715d8e7f0df7f5e55ca which is
commit a26cc2934331b57b5a7164bff344f0a2ec245fc0 upstream.

Reason for revert:
1. The commit [1] does not land on linux-5.15, so this patch does not
fix anything.

2. Since the fw_devlink improvements series [2] does not land on
linux-5.15, using device_set_fwnode() causes the panel to flash during
bootup.

Incorrect link management may lead to incorrect device initialization,
affecting firmware node links and consumer relationships.
The fwnode setting of panel to the DSI device would cause a DSI
initialization error without series[2], so this patch was reverted to
avoid using the incomplete fw_devlink functionality.

da30a32d2d iio: light: veml6030: fix microlux value calculation
commit 63dd163cd61dda6f38343776b42331cc6b7e56e0 upstream.

The raw value conversion to obtain a measurement in lux as
INT_PLUS_MICRO does not calculate the decimal part properly to display
it as micro (in this case microlux). It only calculates the module to
obtain the decimal part from a resolution that is 10000 times the
provided in the datasheet (0.5376 lux/cnt for the veml6030). The
resulting value must still be multiplied by 100 to make it micro.

This bug was introduced with the original implementation of the driver.

Only the illuminance channel is fixed becuase the scale is non sensical
for the intensity channels anyway.

c5382a5934 staging: iio: frequency: ad9832: fix division by zero in ad9832_calc_freqreg()
commit 6bd301819f8f69331a55ae2336c8b111fc933f3d upstream.

In the ad9832_write_frequency() function, clk_get_rate() might return 0.
This can lead to a division by zero when calling ad9832_calc_freqreg().
The check if (fout > (clk_get_rate(st->mclk) / 2)) does not protect
against the case when fout is 0. The ad9832_write_frequency() function
is called from ad9832_write(), and fout is derived from a text buffer,
which can contain any value.

1dd997e076 wifi: iwlegacy: Clear stale interrupts before resuming device
commit 07c90acb071b9954e1fecb1e4f4f13d12c544b34 upstream.

iwl4965 fails upon resume from hibernation on my laptop. The reason
seems to be a stale interrupt which isn't being cleared out before
interrupts are enabled. We end up with a race beween the resume
trying to bring things back up, and the restart work (queued form
the interrupt handler) trying to bring things down. Eventually
the whole thing blows up.

Fix the problem by clearing out any stale interrupts before
interrupts get enabled during resume.

Here's a debug log of the indicent:

b0b681f307 wifi: ath10k: Fix memory leak in management tx
commit e15d84b3bba187aa372dff7c58ce1fd5cb48a076 upstream.

In the current logic, memory is allocated for storing the MSDU context
during management packet TX but this memory is not being freed during
management TX completion. Similar leaks are seen in the management TX
cleanup logic.

Kmemleak reports this problem as below,

unreferenced object 0xffffff80b64ed250 (size 16):
  comm "kworker/u16:7", pid 148, jiffies 4294687130 (age 714.199s)

commit 31004740e42846a6f0bb255e6348281df3eb8032 upstream.

Use pm_runtime_put in the remove function and pm_runtime_get to disable
RPM on platforms that don't support runtime D3, as re-enabling it through
sysfs auto power control may cause the controller to malfunction. This
can lead to issues such as hotplug devices not being detected due to
failed interrupt generation.

commit fdce49b5da6e0fb6d077986dec3e90ef2b094b50 upstream.

For devm_usb_put_phy(), its comment says it needs to invoke usb_put_phy()
to release the phy, but it does not do that actually, so it can not fully
undo what the API devm_usb_get_phy() does, that is wrong, fixed by using
devres_release() instead of devres_destroy() within the API.

commit de96f6a3003513c796bbe4e23210a446913f5c00 upstream.

This change fixes a rare issue where the PHY fails to detect a link
due to incorrect reset behavior.

The SW_RESET definition was incorrectly assigned to bit 14, which is the
Digital Restart bit according to the datasheet. This commit corrects
SW_RESET to bit 15 and assigns DIG_RESTART to bit 14 as per the
datasheet specifications.

The SW_RESET define is only used in the phy_reset function, which fully
re-initializes the PHY after the reset is performed. The change in the
bit definitions should not have any negative impact on the functionality
of the PHY.

commit 4c262801ea60c518b5bebc22a09f5b78b3147da2 upstream.

The existing code moves VF to the same namespace as the synthetic NIC
during netvsc_register_vf(). But, if the synthetic device is moved to a
new namespace after the VF registration, the VF won't be moved together.

To make the behavior more consistent, add a namespace check for synthetic
NIC's NETDEV_REGISTER event (generated during its move), and move the VF
if it is not in the same namespace.

commit 8fa73ee44daefc884c53a25158c25a4107eb5a94 upstream.

Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state
detection issue.

The _LID device incorrectly returns the lid status as "closed" during
boot, causing the system to enter a suspend loop right after booting.

The quirk ensures that the correct lid state is reported initially,
preventing the system from immediately suspending after startup.  It
only addresses the initial lid state detection and ensures proper
system behavior upon boot.

8450a5fb62 ACPI: resource: Add LG 16T90SP to irq1_level_low_skip_override[]
commit 53f1a907d36fb3aa02a4d34073bcec25823a6c74 upstream.

The LG Gram Pro 16 2-in-1 (2024) the 16T90SP has its keybopard IRQ (1)
described as ActiveLow in the DSDT, which the kernel overrides to EdgeHigh
which breaks the keyboard.

Add the 16T90SP to the irq1_level_low_skip_override[] quirk table to fix
this.

2dd30f8c30 drm/amd: Guard against bad data for ATIF ACPI method
commit bf58f03931fdcf7b3c45cb76ac13244477a60f44 upstream.

If a BIOS provides bad data in response to an ATIF method call
this causes a NULL pointer dereference in the caller.

fd0a3436e4 r8169: avoid unsolicited interrupts
[ Upstream commit 10ce0db787004875f4dba068ea952207d1d8abeb ]

It was reported that after resume from suspend a PCI error is logged
and connectivity is broken. Error message is:
PCI error (cmd = 0x0407, status_errs = 0x0000)
The message seems to be a red herring as none of the error bits is set,
and the PCI command register value also is normal. Exception handling
for a PCI error includes a chip reset what apparently brakes connectivity
here. The interrupt status bit triggering the PCI error handling isn't
actually used on PCIe chip versions, so it's not clear why this bit is
set by the chip. Fix this by ignoring this bit on PCIe chip versions.

57b7448029 net: usb: usbnet: fix name regression
[ Upstream commit 8a7d12d674ac6f2147c18f36d1e15f1a48060edf ]

The fix for MAC addresses broke detection of the naming convention
because it gave network devices no random MAC before bind()
was called. This means that the check for the local assignment bit
was always negative as the address was zeroed from allocation,
instead of from overwriting the MAC with a unique hardware address.

The correct check for whether bind() has altered the MAC is
done with is_zero_ether_addr

6d2bfe9d4d usb: typec: altmode should keep reference to parent
[ Upstream commit befab3a278c59db0cc88c8799638064f6d3fd6f8 ]

The altmode device release refers to its parent device, but without keeping
a reference to it.

When registering the altmode, get a reference to the parent and put it in
the release function.

Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issues
like this:

In target_alloc_device(), if allocing memory for dev queues fails, then
dev will be freed by dev->transport->free_device(), but dev->transport
is not initialized at that time, which will lead to a null pointer
reference problem.

Fixing this bug by freeing dev with hba->backend->ops->free_device().

8ffd74f354 genetlink: hold RCU in genlmsg_mcast()
[ Upstream commit 56440d7ec28d60f8da3bfa09062b3368ff9b16db ]

While running net selftests with CONFIG_PROVE_RCU_LIST=y I saw
one lockdep splat [1].

genlmsg_mcast() uses for_each_net_rcu(), and must therefore hold RCU.

Instead of letting all callers guard genlmsg_multicast_allns()
with a rcu_read_lock()/rcu_read_unlock() pair, do it in genlmsg_mcast().

This also means the @flags parameter is useless, we need to always use
GFP_ATOMIC.

654dc34065 net: systemport: fix potential memory leak in bcm_sysport_xmit()
[ Upstream commit c401ed1c709948e57945485088413e1bb5e94bd1 ]

The bcm_sysport_xmit() returns NETDEV_TX_OK without freeing skb
in case of dma_map_single() fails, add dev_kfree_skb() to fix it.

34b9267737 drm/msm/dsi: fix 32-bit signed integer extension in pclk_rate calculation
[ Upstream commit 358b762400bd94db2a14a72dfcef74c7da6bd845 ]

When (mode->clock * 1000) is larger than (1<<31), int to unsigned long
conversion will sign extend the int to 64 bits and the pclk_rate value
will be incorrect.

Fix this by making the result of the multiplication unsigned.

Note that above (1<<32) would still be broken and require more changes, but
its unlikely anyone will need that anytime soon.
