Fix this issue by adding nfp_nsp_close(nsp) in the error path.
How do you think about a wording variant like the following? Subject: [PATCH v2] nfp: abm: Fix incomplete release of system resources in nfp_abm_vnic_set_mac() Change description: … Thus add a call of the function “nfp_nsp_close” for the completion of the exception handling. …
+++ b/drivers/net/ethernet/netronome/nfp/abm/main.c@@ -283,6 +283,7 @@ nfp_abm_vnic_set_mac(struct nfp_pf *pf, struct nfp_abm *abm, struct nfp_net *nn, if (!nfp_nsp_has_hwinfo_lookup(nsp)) { nfp_warn(pf->cpp, "NSP doesn't support PF MAC generation\n"); eth_hw_addr_random(nn->dp.netdev); + nfp_nsp_close(nsp); return; }
I suggest to reconsider the order for resource clean-up function calls a bit more. + nfp_nsp_close(nsp); - eth_hw_addr_random(nn->dp.netdev); - return; + goto generate_random_address; Should such a jump target be added in another update step? Would you like to add the tag “Fixes”? Regards, Markus
