Pull networking updates from Jakub Kicinski: "Core & protocols: - Support HW queue leasing, allowing containers to be granted access to HW queues for zero-copy operations and AF_XDP - Number of code moves to help the compiler with inlining. Avoid output arguments for returning drop reason where possible - Rework drop handling within qdiscs to include more metadata about the reason and dropping qdisc in the tracepoints - Remove the rtnl_lock use from IP Multicast Routing - Pack size information into the Rx Flow Steering table pointer itself. This allows making the table itself a flat array of u32s, thus making the table allocation size a power of two - Report TCP delayed ack timer information via socket diag - Add ip_local_port_step_width sysctl to allow distributing the randomly selected ports more evenly throughout the allowed space - Add support for per-route tunsrc in IPv6 segment routing - Start work of switching sockopt handling to iov_iter - Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid buffer size drifting up - Support MSG_EOR in MPTCP - Add stp_mode attribute to the bridge driver for STP mode selection. This addresses concerns about call_usermodehelper() usage - Remove UDP-Lite support (as announced in 2023) - Remove support for building IPv6 as a module. Remove the now unnecessary function calling indirection Cross-tree stuff: - Move Michael MIC code from generic crypto into wireless, it's considered insecure but some WiFi networks still need it Netfilter: - Switch nft_fib_ipv6 module to no longer need temporary dst_entry object allocations by using fib6_lookup() + RCU.

scsi: bsg: fix buffer overflow in scsi_bsg_uring_cmd()

2026-04-10T12:41:26+00:00

The bounds checking in scsi_bsg_uring_cmd() does not work because cmd->request_len is a u32 and scmd->cmd_len is a u16. We check that scmd->cmd_len is valid but if the cmd->request_len is more than USHRT_MAX it would still lead to a buffer overflow when we do the copy_from_user().

scsi: qla2xxx: Use nr_cpu_ids instead of NR_CPUS for qp_cpu_map allocation

2026-04-09T02:33:39+00:00

Change the memory allocation for qp_cpu_map to use the actual number of CPUs ('nr_cpu_ids') instead of the maximum possible CPUs ('NR_CPUS'). This saves memory on systems where the maximum CPU limit is much higher than the active CPU count.

scsi: sd: fix missing put_disk() when device_add(&disk_dev) fails

2026-04-09T02:10:44+00:00

If device_add(&sdkp->disk_dev) fails, put_device() runs scsi_disk_release(), which frees the scsi_disk but leaves the gendisk referenced. The device_add_disk() error path in sd_probe() calls put_disk(gd); call put_disk(gd) here to mirror that cleanup.

scsi: storvsc: Handle PERSISTENT_RESERVE_IN truncation for Hyper-V vFC

2026-04-09T01:52:06+00:00

The storvsc driver has become stricter in handling SRB status codes returned by the Hyper-V host. When using Virtual Fibre Channel (vFC) passthrough, the host may return SRB_STATUS_DATA_OVERRUN for PERSISTENT_RESERVE_IN commands if the allocation length in the CDB does not match the host's expected response size. Currently, this status is treated as a fatal error, propagating Host_status=0x07 [DID_ERROR] to the SCSI mid-layer. This causes userspace storage utilities (such as sg_persist) to fail with transport errors, even when the host has actually returned the requested reservation data in the buffer. Refactor the existing command-specific workarounds into a new helper function, storvsc_host_mishandles_cmd(), and add PERSISTENT_RESERVE_IN to the list of commands where SRB status errors should be suppressed for vFC devices. This ensures that the SCSI mid-layer processes the returned data buffer instead of terminating the command.

scsi: iscsi_tcp: Remove unneeded selections of CRYPTO and CRYPTO_MD5

2026-04-09T01:41:39+00:00

As far as I can tell, CRYPTO_MD5 has been unnecessary here ever since it was added by commit c899e4ef96f0 ("[SCSI] open-iscsi/linux-iscsi-5 Initiator: Kconfig update") in 2005. CRYPTO was needed until commit 92186c1455a2 ("scsi: iscsi_tcp: Switch to using the crc32c library"), but is no longer needed. Remove these unnecessary kconfig selections.

Merge patch series "Update lpfc to revision 15.0.0.0"

2026-04-03T01:35:53+00:00

Justin Tee says: Update lpfc to revision 15.0.0.0 This patch set adds support for the G8 ASIC found on the LPe42100 series adapter models. Updates are made to irq affinity assignment, mailbox command handling related to initialization, SGL construction, firmware download diagnostics, and the removal of an outdated performance feature. We also add 128G link speed selection and support. The patches were cut against Martin's 7.1/scsi-queue tree.
