Rx processing is handled by the mbx_task that is not always\ncancelled before calling the new consolidated mailbox deinit function.\nMoreover, in the reset path idpf_intr_rel() reschedules it after the deinit\nis done. This leads to mbx_task referencing the freed mailbox and causing\nKASAN warnings.\n\nTo remedy this, in the init path, do the first queueing of mbx_task in\nidpf_init_dflt_mbx(), in deinit and reset, always cancel the task in\nidpf_deinit_dflt_mbx() and in every flow first call idpf_mb_intr_rel_irq().\n\nReviewed-by: Emil Tantilov <emil.s.tantilov@intel.com>\nReviewed-by: Michal Kubiak <michal.kubiak@intel.com>\nSigned-off-by: Larysa Zaremba <larysa.zaremba@intel.com>\nTested-by: Samuel Salin <Samuel.salin@intel.com>\nSigned-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>\n---\n drivers/net/ethernet/intel/idpf/idpf.h | 1 +\n drivers/net/ethernet/intel/idpf/idpf_lib.c | 9 ++++-----\n drivers/net/ethernet/intel/idpf/idpf_virtchnl.c | 6 +++++-\n 3 files changed, 10 insertions(+), 6 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/idpf/idpf.h b/drivers/net/ethernet/intel/idpf/idpf.h\nindex 679539a1b947..1d0e32e47e87 100644\n--- a/drivers/net/ethernet/intel/idpf/idpf.h\n+++ b/drivers/net/ethernet/intel/idpf/idpf.h\n@@ -984,6 +984,7 @@ void idpf_vc_event_task(struct work_struct *work);\n void idpf_dev_ops_init(struct idpf_adapter *adapter);\n void idpf_vf_dev_ops_init(struct idpf_adapter *adapter);\n int idpf_intr_req(struct idpf_adapter *adapter);\n+void idpf_mb_intr_rel_irq(struct idpf_adapter *adapter);\n void idpf_intr_rel(struct idpf_adapter *adapter);\n u16 idpf_get_max_tx_hdr_size(struct idpf_adapter *adapter);\n int idpf_initiate_soft_reset(struct idpf_vport *vport,\ndiff --git a/drivers/net/ethernet/intel/idpf/idpf_lib.c b/drivers/net/ethernet/intel/idpf/idpf_lib.c\nindex 0d131bf0993e..7988836fbae0 100644\n--- a/drivers/net/ethernet/intel/idpf/idpf_lib.c\n+++ b/drivers/net/ethernet/intel/idpf/idpf_lib.c\n@@ -68,9 +68,11 @@ static void idpf_deinit_vector_stack(struct idpf_adapter *adapter)\n * This will also disable interrupt mode and queue up mailbox task.
