scsi: fnic: Fix missed link-up when critical IRQ targets offline CPU

2026-09-10T01:44:18Z

When CPU Hyper Threading is disabled, sibling CPUs remain present but are reported offline. Managed MSI-X IRQs can still receive affinity masks that include those offline CPUs. If a driver-critical vector is managed, it can be parked on an offline CPU and the driver may miss critical events such as link-up. Keep driver-critical vectors unmanaged so they can be migrated by the IRQ core when their target CPU is offlined. Since HWQ-0 is unmanaged now, in some queue combinations there can be no mappings to it in mq_map. So without the blk-mq fix mentioned below, system may crash during cpu offline/online tests.

treewide: refresh kmalloc_obj() conversions

2026-09-05T04:37:00Z

This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

scsi: fnic: Initialize the NVMe local port info before registering

2026-08-29T01:33:03Z

nvfnic_add_lport() declares struct nvme_fc_port_info on the stack and fills in four of its five members, leaving dev_loss_tmo holding whatever the stack happened to contain before the call. The structure is then handed to nvme_fc_register_localport(). nvfnic_add_tport(), which registers the remote port a few lines further down, memsets its own struct nvme_fc_port_info first, so only the local port path passes uninitialized data across the transport interface. The NVMe/FC transport documents dev_loss_tmo as "Used only on a remoteport" and does not read it in nvme_fc_register_localport(), so there is no behavioural change today. Initialize the structure anyway: the driver must not depend on which members the transport happens to consume, and any member added to struct nvme_fc_port_info later would silently start out as stack garbage.

scsi: fnic: Fix built-in NVMe/FC build

2026-08-11T01:24:01Z

The fnic NVMe/FC code is guarded with IS_ENABLED(CONFIG_NVME_FC). That also evaluates true when NVME_FC is built as a module. When fnic is built into vmlinux and NVME_FC=m, fnic_nvme.o still references the NVMe/FC transport helpers even though those helpers are not reachable from built-in code. The final vmlinux link then fails with undefined nvme_fc_* symbols. Use IS_REACHABLE(CONFIG_NVME_FC) for the fnic NVMe/FC implementation and prototypes so built-in fnic uses the disabled stubs unless the NVMe/FC transport is reachable.

scsi: fnic: Fix invalid comparison for error

2026-08-07T18:09:34Z

The current comparison err != ERR_ECMDUNKNOWN is useless because err < 0 and ERR_ECMDUNKNOWN == 5. The logic is that if the CMD_CAPABILITY command was executed, there is no need to respond to unknown errors. Therefore, the sign of the number in the comparison must be changed.

scsi: fnic: Use GFP_ATOMIC for VLAN alloc under spinlock

2026-08-07T17:32:53Z

fnic_fcoe_process_vlan_resp() allocates a VLAN descriptor with kzalloc_obj() (default GFP_KERNEL) while holding vlans_lock via spin_lock_irqsave(). GFP_KERNEL may sleep, which is not allowed in this atomic context and can trigger a sleeping-from-invalid-context warning or deadlock. Pass GFP_ATOMIC so the allocation is safe under the IRQ-safe spinlock.
