Subject: [PATCH 0/2] scsi: qla2xxx: flexible array / field-spanning write issue
Date: Fri, 25 Jul 2025 14:27:30 -0700 [thread overview]
Message-ID: <20250725212732.2038027-1-cleech@redhat.com> (raw)
Bryan Gurney was running into these field-spanning write warnings while
testing some in-progress NVMe FPIN work with qla2xxx.
https://lore.kernel.org/linux-nvme/20250709211919.49100-1-bgurney@redhat.com/
> kernel: memcpy: detected field-spanning write (size 60) of single field
> "((uint8_t *)fpin_pkt + buffer_copy_offset)"
> at drivers/scsi/qla2xxx/qla_isr.c:1221 (size 44)
I think these changes should fix up the non-standard flexible array
allocations, and fix he warning for Bryan's testing.
Chris Leech (2):
scsi: qla2xxx: replace non-standard flexible array purex_item.iocb
scsi: qla2xxx: unwrap purex_item.iocb.iocb so that __counted_by can be
used
