https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260818 Bug ID: 260818 Summary: ctfconvert errors when processing iwlwifi object files Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: markj@FreeBSD.org $ cd sys/modules/iwlwifi $ make -s WITH_CTF= DEBUG_FLAGS=-g ctfconvert: failed to resolve the following types: struct 65360 <ff50>: failed to size member "desc" of type (65453 <ffad>) ERROR: ctfconvert: failed to resolve types ctfconvert: failed to resolve the following types: struct 66979 <105a3>: failed to size member "desc" of type (67072 <10600>) ERROR: ctfconvert: failed to resolve types ctfconvert: failed to resolve the following types: struct 66556 <103fc>: failed to size member "desc" of type (66649 <10459>) ERROR: ctfconvert: failed to resolve types ctfconvert: failed to resolve the following types: ... Looks like all the warnings are about the "desc" field of struct iwl_p2p_noa_attr, which is: struct ieee80211_p2p_noa_desc desc[IWL_P2P_NOA_DESC_COUNT]; and we have struct ieee80211_p2p_noa_desc { /* TODO FIXME */ }; Adding a dummy field to the latter "fixes" the problem. Looking at ctfconvert, empty structs and unions are permitted and handled, as are flexible array members. The problem is that here we have an array of empty structs. I think die_sou_resolve() needs some extra logic to handle this case. -- You are receiving this mail because: You are the assignee for the bug.
