Entries are added in qla2xxx_process_purls_iocb() from the\nresponse queue ISR (under the qpair qp_lock), while they are removed from\nqla2xxx_process_purls_pkt() (DPC/purex worker), qla_nvme_xmt_ls_rsp()\n(NVMe-FC transport callback) and qla_nvme_release_lsrsp_cmd_kref() (SRB\ncompletion). The qpair qp_lock cannot serialize this per-fcport list since\nmultiqueue adapters add entries through different qpairs, so a concurrent\nadd and delete (or two concurrent deletes) can corrupt the list pointers.\n\nIntroduce a dedicated per-fcport spinlock, unsol_ctx_lock, initialized in\nqla2x00_alloc_fcport(), and take it around every list_add_tail()/list_del()\non unsol_ctx_head. The add nests under the existing qp_lock; no delete path\ntakes qp_lock, so the lock order is consistent and deadlock free.","state":0,"publishedAt":"2026-09-25T10:21:29.521+00:00","modifiedAt":"2026-10-21T12:53:02.776+00:00","affected":[{"ecosystem":"Vendor
