With ACPI in place, gicv2m_get_fwnode() is registered with the pci subsystem as pci_msi_get_fwnode_cb(), which may get invoked at runtime during a PCI host bridge probe. But, the call back is wrongly marked as __init, causing it to be freed, while being registered with the PCI subsystem and could trigger: Unable to handle kernel paging request at virtual address ffff8000816c0400 gicv2m_get_fwnode+0x0/0x58 (P) pci_set_bus_msi_domain+0x74/0x88 pci_register_host_bridge+0x194/0x548 This is easily reproducible on a Juno board with ACPI boot.

Reconfiguration of netdev may trigger close/open procedure which can break FIFO status by adjusting the amount of empty slots for TX timestamps. But it is not really needed because timestamps for the packets sent over the wire still can be retrieved. On the other side, during netdev close procedure any skbs waiting for TX timestamps can be leaked because there is no cleaning procedure called.

2025-04-25net: mscc: ocelot: delete PVID VLAN when readding it as non-PVIDVladimir Oltean
The following set of commands: ip link add br0 type bridge vlan_filtering 1 # vlan_default_pvid 1 is implicit ip link set swp0 master br0 bridge vlan add dev swp0 vid 1 should result in the dropping of untagged and 802.1p-tagged traffic, but we see that it continues to be accepted. Whereas, had we deleted VID 1 instead, the aforementioned dropping would have worked This is because the ANA_PORT_DROP_CFG update logic doesn't run, because ocelot_vlan_add() only calls ocelot_port_set_pvid() if the new VLAN has the BRIDGE_VLAN_INFO_PVID flag. Similar to other drivers like mt7530_port_vlan_add() which handle this case correctly, we need to test whether the VLAN we're changing used to have the BRIDGE_VLAN_INFO_PVID flag, but lost it now. That amounts to a PVID deletion and should be treated as such. Regarding blame attribution: this never worked properly since the introduction of bridge VLAN filtering in commit 7142529f1688 ("net: mscc: ocelot: add VLAN filtering"). However, there was a significant paradigm shift which aligned the ANA_PORT_DROP_CFG register with the PVID concept rather than with the native VLAN concept, and that change wasn't targeted for 'stable'. Realistically, that is as far as this fix needs to be propagated to.

2025-04-25vmxnet3: Fix malformed packet sizing in vmxnet3_process_xdpDaniel Borkmann
vmxnet3 driver's XDP handling is buggy for packet sizes using ring0 (that is, packet sizes between 128 - 3k bytes). We noticed MTU-related connectivity issues with Cilium's service load- balancing in case of vmxnet3 as NIC underneath. A simple curl to a HTTP backend service where the XDP LB was doing IPIP encap led to overly large packet sizes but only for *some* of the packets (e.g. HTTP GET request) while others (e.g. the prior TCP 3WHS) looked completely fine on the wire. In fact, the pcap recording on the backend node actually revealed that the node with the XDP LB was leaking uninitialized kernel data onto the wire for the affected packets, for example, while the packets should have been 152 bytes their actual size was 1482 bytes, so the remainder after 152 bytes was padded with whatever other data was in that page at the time (e.g. we saw user/payload data from prior processed packets). We only noticed this through an MTU issue, e.g. when the XDP LB node and the backend node both had the same MTU (e.g. 1500) then the curl request got dropped on the backend node's NIC given the packet was too large even though the IPIP-encapped packet normally would never even come close to the MTU limit. Lowering the MTU on the XDP LB (e.g. 1480) allowed to let the curl request succeed (which also indicates that the kernel ignored the padding, and thus the issue wasn't very user-visible). Commit e127ce7699c1 ("vmxnet3: Fix missing reserved tailroom") was too eager to also switch xdp_prepare_buff() from rcd->len to rbi->len. It really needs to stick to rcd->len which is the actual packet length from the descriptor. The latter we also feed into vmxnet3_process_xdp_small(), by the way, and it indicates the correct length needed to initialize the xdp->{data,data_end} parts. For e127ce7699c1 ("vmxnet3: Fix missing reserved tailroom") the relevant part was adapting xdp_init_buff() to address the warning given the xdp_data_hard_end() depends on xdp->frame_sz. With that fixed, traffic on the wire looks good again.

The lesson to learn from this might just be that we need to threaten code removal more often!? - Fix a regression introduced by enabling large folios for lage logical block sizes. This has caused issues for noref migration with large folios due to sleeping while in an atomic context. New sleeping variants of pagecache lookup helpers are introduced. These helpers take the folio lock instead of the mapping's private spinlock. The problematic users are converted to the sleeping variants and serialize against noref migration. Atomic users will bail on seeing the new BH_Migrate flag. This also shrinks the critical region of the mapping's private lock and the new blocking callers reduce contention on the spinlock for bdev mappings. - Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The first bug is using a mountpoint that is located on a mount we're not holding a reference to. The second bug is putting the mountpoint after we've called namespace_unlock() as it's no longer guaranteed that it does stay a mountpoint. - Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code just to query i_mode instead of simply querying the inode directly. This also avoids lifetime issues for the dm code by an earlier bugfix this cycle that moved bdev_statx() handling into vfs_getattr_nosec(). - Fix AT_FDCWD handling with getname_maybe_null() in the xattr code. - Fix a performance regression for files when multiple callers issue a close when it's not the last reference. - Remove a duplicate noinline annotation from pipe_clear_nowait(). * tag 'vfs-6.15-rc4.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fs/xattr: Fix handling of AT_FDCWD in setxattrat(2) and getxattrat(2) MAINTAINERS: hfs/hfsplus: add myself as maintainer splice: remove duplicate noinline from pipe_clear_nowait devtmpfs: don't use vfs_getattr_nosec to query i_mode fix a couple of races in MNT_TREE_BENEATH handling by do_move_mount() fs: fall back to file_ref_put() for non-last reference mm/migrate: fix sleep in atomic for large folios and buffer heads fs/ext4: use sleeping version of sb_find_get_block() fs/jbd2: use sleeping version of __find_get_block() fs/ocfs2: use sleeping version of __find_get_block() fs/buffer: use sleeping version of __find_get_block() fs/buffer: introduce sleeping flavors for pagecache lookups MAINTAINERS: add HFS/HFS+ maintainers fs/buffer: split locking for pagecache lookups

2025-04-25Drivers: hv: Fix bad ref to hv_synic_eventring_tail when CPU goes offlineMichael Kelley
When a CPU goes offline, hv_common_cpu_die() frees the hv_synic_eventring_tail memory for the CPU.

2025-04-25Bluetooth: btintel_pcie: Add additional to checks to clear TX/RX pathsKiran K
Due to a hardware issue, there is a possibility that the driver may miss an MSIx interrupt on the RX/TX data path. Since the TX and RX paths are independent, when a TX MSIx interrupt occurs, the driver can check the RX queue for any pending data and process it if present. The same approach applies to the RX path.

2025-04-25Bluetooth: btusb: avoid NULL pointer dereference in skb_dequeue()En-Wei Wu
A NULL pointer dereference can occur in skb_dequeue() when processing a QCA firmware crash dump on WCN7851 (0489:e0f3). [ 93.672166] Bluetooth: hci0: ACL memdump size(589824) [ 93.672475] BUG: kernel NULL pointer dereference, address: 0000000000000008 [ 93.672517] Workqueue: hci0 hci_devcd_rx [bluetooth] [ 93.672598] RIP: 0010:skb_dequeue+0x50/0x80 The issue stems from handle_dump_pkt_qca() returning 0 even when a dump packet is successfully processed. This is because it incorrectly forwards the return value of hci_devcd_init() (which returns 0 on success). As a result, the caller (btusb_recv_acl_qca() or btusb_recv_evt_qca()) assumes the packet was not handled and passes it to hci_recv_frame(), leading to premature kfree() of the skb. Later, hci_devcd_rx() attempts to dequeue the same skb from the dump queue, resulting in a NULL pointer dereference. Fix this by: 1. Making handle_dump_pkt_qca() return 0 on success and negative errno on failure, consistent with kernel conventions. 2. Splitting dump packet detection into separate functions for ACL and event packets for better structure and readability. This ensures dump packets are properly identified and consumed, avoiding double handling and preventing NULL pointer access.

2025-04-25cpufreq: ACPI: Re-sync CPU boost state on system resumeViresh Kumar
During CPU hotunplug events (such as those occurring during suspend/resume cycles), platform firmware may modify the CPU boost state. If boost was disabled prior to CPU removal, it correctly remains disabled upon re-plug. However, if firmware re-enables boost while the CPU is offline, the CPU may return with boost enabled—even if it was originally disabled—once it is hotplugged back in. This leads to inconsistent behavior and violates user or kernel policy expectations. To maintain consistency, ensure the boost state is re-synchronized with the kernel policy when a CPU is hotplugged back in. Note: This re-synchronization is not necessary during the initial call to ->init() for a CPU, as the cpufreq core handles it via cpufreq_online(). At that point, acpi_cpufreq_driver.boost_enabled is initialized to the value returned by boost_state(0).

For example, in Winbond SPINAND flash memory devices, the `write_cache` and `update_cache` operation variants have zero dummy bytes. Calculating the duration for SPI memory operations with zero dummy bytes causes a divide error when `ncycles` is calculated in the spi_mem_calc_op_duration().

The recent move of the bdev_statx call to the low-level vfs_getattr_nosec helper caused it being used by devtmpfs, which leads to deadlocks in md teardown due to the block device lookup and put interfering with the unusual lifetime rules in md. But as handle_remove only works on inodes created and owned by devtmpfs itself there is no need to use vfs_getattr_nosec vs simply reading the mode from the inode directly.

2025-04-24vxlan: vnifilter: Fix unlocked deletion of default FDB entryIdo Schimmel
When a VNI is deleted from a VXLAN device in 'vnifilter' mode, the FDB entry associated with the default remote (assuming one was configured) is deleted without holding the hash lock. This is wrong and will result in a warning [1] being generated by the lockdep annotation that was added by commit ebe642067455 ("vxlan: Create wrappers for FDB lookup"). Reproducer: # ip link add vx0 up type vxlan dstport 4789 external vnifilter local 192.0.2.1 # bridge vni add vni 10010 remote 198.51.100.1 dev vx0 # bridge vni del vni 10010 dev vx0 Fix by acquiring the hash lock before the deletion and releasing it afterwards. Blame the original commit that introduced the issue rather than the one that exposed it.
