The function mod_hdcp_hdcp1_enable_encryption() calls the function get_first_active_display(), but does not check its return value. The return value is a null pointer if the display list is empty.

Similar to the changes made for VCN v4.0.5 where readback to post the writes to avoid race with the doorbell, the addition of register readback support in other VCN versions is intended to prevent potential race conditions, even though such issues have not been observed yet.

2025-05-29net: lan966x: Make sure to insert the vlan tags also in host modeHoratiu Vultur
When running these commands on DUT (and similar at the other end) ip link set dev eth0 up ip link add link eth0 name eth0.10 type vlan id 10 ip addr add 10.0.0.1/24 dev eth0.10 ip link set dev eth0.10 up ping 10.0.0.2 The ping will fail. The reason why is failing is because, the network interfaces for lan966x have a flag saying that the HW can insert the vlan tags into the frames(NETIF_F_HW_VLAN_CTAG_TX). Meaning that the frames that are transmitted don't have the vlan tag inside the skb data, but they have it inside the skb. We already get that vlan tag and put it in the IFH but the problem is that we don't configure the HW to rewrite the frame when the interface is in host mode. The fix consists in actually configuring the HW to insert the vlan tag if it is different than 0.

2025-05-29acpi-cpufreq: Fix nominal_freq units to KHz in get_max_boost_ratio()Gautham R. Shenoy
commit 083466754596 ("cpufreq: ACPI: Fix max-frequency computation") modified get_max_boost_ratio() to return the nominal_freq advertised in the _CPC object. This was for the purposes of computing the maximum frequency. The frequencies advertised in _CPC objects are in MHz. However, cpufreq expects the frequency to be in KHz. Since the nominal_freq returned by get_max_boost_ratio() was not in KHz but instead in MHz,the cpuinfo_max_frequency that was computed using this nominal_freq was incorrect and an invalid value which resulted in cpufreq reporting the P0 frequency as the cpuinfo_max_freq. Fix this by converting the nominal_freq to KHz before returning the same from get_max_boost_ratio().

2025-05-29drm/xe/bo: optimise CCS case for WB pagesMatthew Auld
Dealing with CCS state is significant on LNL+, where we end up clearing the compression state on every page alloc using the blitter for user buffers, including also saving and restoring it when moving between domains, plus we need to alloc extra pages to hold the raw CCS state for the save step. However all compression PAT modes, on platforms like LNL, also require coh_none, meaning that only WC memory can use compression in the first place. With this we can be sneaky and completely ignore CCS for WB buffers, which is likely the common case anyway. This would then skip all blitter moves/clears between sys <-> tt and then also means we can drop the extra CCS pages. This should be safe since there is no way to interact with the compression state (potentially uncleared) without using a PAT enabled index (which is rejected at bind), including if trying to be malicious and copy the raw CCS state from userpace, which should give back all zeroes if the src surface (indirect) is lacking compressed PAT index.

2025-05-29net: stmmac: platform: guarantee uniqueness of bus_idQuentin Schulz
bus_id is currently derived from the ethernetX alias. If one is missing for the device, 0 is used. If ethernet0 points to another stmmac device or if there are 2+ stmmac devices without an ethernet alias, then bus_id will be 0 for all of those. This is an issue because the bus_id is used to generate the mdio bus id (new_bus->id in drivers/net/ethernet/stmicro/stmmac/stmmac_mdio.c stmmac_mdio_register) and this needs to be unique. This allows to avoid needing to define ethernet aliases for devices with multiple stmmac controllers (such as the Rockchip RK3588) for multiple stmmac devices to probe properly. Obviously, the bus_id isn't guaranteed to be stable across reboots if no alias is set for the device but that is easily fixed by simply adding an alias if this is desired.

2025-05-29can: kvaser_pciefd: refine error prone echo_skb_max handling logicFedor Pchelkin
echo_skb_max should define the supported upper limit of echo_skb[] allocated inside the netdevice's priv. The corresponding size value provided by this driver to alloc_candev() is KVASER_PCIEFD_CAN_TX_MAX_COUNT which is 17. But later echo_skb_max is rounded up to the nearest power of two (for the max case, that would be 32) and the tx/ack indices calculated further during tx/rx may exceed the upper array boundary. Kasan reported this for the ack case inside kvaser_pciefd_handle_ack_packet(), though the xmit function has actually caught the same thing earlier. BUG: KASAN: slab-out-of-bounds in kvaser_pciefd_handle_ack_packet+0x2d7/0x92a drivers/net/can/kvaser_pciefd.c:1528 Read of size 8 at addr ffff888105e4f078 by task swapper/4/0 CPU: 4 UID: 0 PID: 0 Comm: swapper/4 Not tainted 6.15.0 #12 PREEMPT(voluntary) Call Trace: <IRQ> dump_stack_lvl lib/dump_stack.c:122 print_report mm/kasan/report.c:521 kasan_report mm/kasan/report.c:634 kvaser_pciefd_handle_ack_packet drivers/net/can/kvaser_pciefd.c:1528 kvaser_pciefd_read_packet drivers/net/can/kvaser_pciefd.c:1605 kvaser_pciefd_read_buffer drivers/net/can/kvaser_pciefd.c:1656 kvaser_pciefd_receive_irq drivers/net/can/kvaser_pciefd.c:1684 kvaser_pciefd_irq_handler drivers/net/can/kvaser_pciefd.c:1733 __handle_irq_event_percpu kernel/irq/handle.c:158 handle_irq_event kernel/irq/handle.c:210 handle_edge_irq kernel/irq/chip.c:833 __common_interrupt arch/x86/kernel/irq.c:296 common_interrupt arch/x86/kernel/irq.c:286 </IRQ> Tx max count definitely matters for kvaser_pciefd_tx_avail(), but for seq numbers' generation that's not the case - we're free to calculate them as would be more convenient, not taking tx max count into account. The only downside is that the size of echo_skb[] should correspond to the max seq number (not tx max count), so in some situations a bit more memory would be consumed than could be. Thus make the size of the underlying echo_skb[] sufficient for the rounded max tx value. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
