2026-01-04net: wwan: iosm: Fix memory leak in ipc_mux_deinit()Zilin Guan
Commit 1f52d7b62285 ("net: wwan: iosm: Enable M.2 7360 WWAN card support") allocated memory for pp_qlt in ipc_mux_init() but did not free it in ipc_mux_deinit(). This results in a memory leak when the driver is unloaded. Free the allocated memory in ipc_mux_deinit() to fix the leak.

2026-01-04net/mlx5e: Don't print error message due to invalid moduleGal Pressman
Dumping module EEPROM on newer modules is supported through the netlink interface only. Querying with old userspace ethtool (or other tools, such as 'lshw') which still uses the ioctl interface results in an error message that could flood dmesg (in addition to the expected error return value). The original message was added under the assumption that the driver should be able to handle all module types, but now that such flows are easily triggered from userspace, it doesn't serve its purpose. Change the log level of the print in mlx5_query_module_eeprom() to debug.

2026-01-04net/mlx5e: Don't gate FEC histograms on ppcnt_statistical_groupAlexei Lazar
Currently, the ppcnt_statistical_group capability check incorrectly gates access to FEC histogram statistics. This capability applies only to statistical and physical counter groups, not for histogram data. Restrict the ppcnt_statistical_group check to the Physical_Layer_Counters and Physical_Layer_Statistical_Counters groups. Histogram statistics access remains gated by the pphcr capability. The issue is harmless as of today, as it happens that ppcnt_statistical_group is set on all existing devices that have pphcr set.

2026-01-04net/mlx5: Lag, multipath, give priority for routes with smaller network prefixPatrisious Haddad
Today multipath offload is controlled by a single route and the route controlling is selected if it meets one of the following criteria: 1. No controlling route is set. 2. New route destination is the same as old one. 3. New route metric is lower than old route metric. This can cause unwanted behaviour in case a new route is added with a smaller network prefix which should get the priority. Fix this by adding a new criteria to give priority to new route with a smaller network prefix.

2026-01-04net: sock: fix hardened usercopy panic in sock_recv_errqueueWeiming Shi
skbuff_fclone_cache was created without defining a usercopy region, [1] unlike skbuff_head_cache which properly whitelists the cb[] field. [2] This causes a usercopy BUG() when CONFIG_HARDENED_USERCOPY is enabled and the kernel attempts to copy sk_buff.cb data to userspace via sock_recv_errqueue() -> put_cmsg(). The crash occurs when: 1. TCP allocates an skb using alloc_skb_fclone() (from skbuff_fclone_cache) [1] 2. The skb is cloned via skb_clone() using the pre-allocated fclone [3] 3. The cloned skb is queued to sk_error_queue for timestamp reporting 4. Userspace reads the error queue via recvmsg(MSG_ERRQUEUE) 5. sock_recv_errqueue() calls put_cmsg() to copy serr->ee from skb->cb [4] 6. __check_heap_object() fails because skbuff_fclone_cache has no usercopy whitelist [5] When cloned skbs allocated from skbuff_fclone_cache are used in the socket error queue, accessing the sock_exterr_skb structure in skb->cb via put_cmsg() triggers a usercopy hardening violation: [ 5.379589] usercopy: Kernel memory exposure attempt detected from SLUB object 'skbuff_fclone_cache' (offset 296, size 16)!

Implement soft_reset, suspend, and resume callbacks using genphy_soft_reset(), genphy_suspend(), and genphy_resume() to fix PHY initialization and power management issues. The soft_reset callback is needed to properly recover the PHY after an ifconfig down/up cycle. Without it, the PHY can remain in power-down state, causing MDIO register access failures during config_init(). The soft reset ensures the PHY is operational before configuration.

Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag") fixed a similar issue in the lan966x driver caused by a NULL pointer dereference. The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic and is susceptible to the same crash. This issue specifically affects the ocelot_vsc7514.c frontend, which leaves unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as it uses the DSA framework which registers all ports. Fix this by checking if the port pointer is valid before accessing it.

2026-01-04bridge: fix C-VLAN preservation in 802.1ad vlan_tunnel egressAlexandre Knecht
When using an 802.1ad bridge with vlan_tunnel, the C-VLAN tag is incorrectly stripped from frames during egress processing. br_handle_egress_vlan_tunnel() uses skb_vlan_pop() to remove the S-VLAN from hwaccel before VXLAN encapsulation. However, skb_vlan_pop() also moves any "next" VLAN from the payload into hwaccel: /* move next vlan tag to hw accel tag */ __skb_vlan_pop(skb, &vlan_tci); __vlan_hwaccel_put_tag(skb, vlan_proto, vlan_tci); For QinQ frames where the C-VLAN sits in the payload, this moves it to hwaccel where it gets lost during VXLAN encapsulation. Fix by calling __vlan_hwaccel_clear_tag() directly, which clears only the hwaccel S-VLAN and leaves the payload untouched. This path is only taken when vlan_tunnel is enabled and tunnel_info is configured, so 802.1Q bridges are unaffected. Tested with 802.1ad bridge + VXLAN vlan_tunnel, verified C-VLAN preserved in VXLAN payload via tcpdump.

2026-01-04IB/cache: update gid cache on client reregister eventEtienne AUJAMES
Some HCAs (e.g: ConnectX4) do not trigger a IB_EVENT_GID_CHANGE on subnet prefix update from SM (PortInfo). Since the commit d58c23c92548 ("IB/core: Only update PKEY and GID caches on respective events"), the GID cache is updated exclusively on IB_EVENT_GID_CHANGE. If this event is not emitted, the subnet prefix in the IPoIB interface’s hardware address remains set to its default value (0xfe80000000000000). Then rdma_bind_addr() failed because it relies on hardware address to find the port GID (subnet_prefix + port GUID). This patch fixes this issue by updating the GID cache on IB_EVENT_CLIENT_REREGISTER event (emitted on PortInfo::ClientReregister=1).

2026-01-04x86/split_lock: Remove dead string when split_lock_detect=fatalRong Zhang
sld_state_show() has a dead str1 below: if (A) { ... } else if (B) { pr_info(... A ? str1 : str2 ...); } where A is always false in the second block, implied by the "if (A) else" pattern. Hence, str2 is always used. This seems to be some mysterious legacy inherited from the earlier patch revisions of ebb1064e7c2e ("x86/traps: Handle #DB for bus lock"). Earlier revisions¹ did enable both sld and bld at the same time to detect non-WB bus_locks when split_lock_detect=fatal, but that's no longer true in the merged revision. Remove it and translate the pr_info() into its equivalent form. ¹ https://lore.kernel.org/r/20201121023624.3604415-3-fenghua.yu@intel.com [ bp: Massage commit message; simplify braces ] Signed-off-by: Rong Zhang <i@rong.moe> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://patch.msgid.link/20251215182907.152881-1-i@rong.moe

2026-01-04x86,fs/resctrl: Refactor domain create/remove using struct rdt_domain_hdrTony Luck
Up until now, all monitoring events were associated with the L3 resource and it made sense to use the L3 specific "struct rdt_mon_domain *" argument to functions operating on domains. Telemetry events will be tied to a new resource with its instances represented by a new domain structure that, just like struct rdt_mon_domain, starts with the generic struct rdt_domain_hdr. Prepare to support domains belonging to different resources by changing the calling convention of functions operating on domains. Pass the generic header and use that to find the domain specific structure where needed.

When kvm.sh is killed, its child processes (make, gcc, qemu, etc.) may continue running. This prevents new kvm.sh instances from starting even though the parent is gone. Add a --kill-previous option that uses fuser(1) to terminate all processes holding the flock file before attempting to acquire it.

It seems the USB combo SS1 and SS2 ref clocks have another gate, unlike the SS0. These gates are part of the TCSR clock controller. At least on Dell XPS 13 (9345), if the ref clock provided by the TCSR clock controller for SS1 PHY is disabled on the clk_disable_unused late initcall, the PHY fails to initialize. It doesn't happen on the SS0 PHY and the SS2 is not used on this device. This doesn't seem to be a problem on CRD though. It might be that the RPMh has a vote for it from some other consumer and does not actually disable it when ther kernel drops its vote. Either way, these TCSR provided clocks seem to be the correct ones for the SS1 and SS2, so use them instead.
