https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250482 Bug ID: 250482 Summary: Missing function in multiple wifi device drivers causing error "need multicast status callback" Product: Base System Version: 12.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Many People Priority: --- Component: wireless Assignee: wireless@FreeBSD.org Reporter: dr2867.business@pacbell.net Also affects i386 as well. I found the cause of the problem with various wireless NICs printing an err= or that says "Need multicast update callback." The problem is driver specific= and multiple drivers have this issue. The cause is that the affected device drivers are not updating the function pointer in the ieee80211com struct in= the file /usr/src/sys/net80211/ieee80211.c. The wlan driver initializes the structure with default values in ieee80211_ifattach. Then the device driver updates the function pointers to point to routines within itself. As it tu= rns out, the drivers that have this problem is missing the callback function. = The drivers that seem have this issue are as follows: an bwi bwn ipw iwi malo mwl ral <--- Confirmed (I'm using this one.) wi wpi Interestingly enough, the same issue exists with the same drives with the promiscuous mode callback as well. There is a third callback only known as= chw that affects even more drivers. Here's the grep that I did on my system: wildfire:/usr/src/sys 114 ### ->grep -Rn ic_update_mcast * dev/iwm/if_iwm.c:6077: ic->ic_update_mcast =3D iwm_update_mcast; dev/wi/if_wi.c:435: ic->ic_update_mcast =3D wi_update_mcast; dev/wpi/if_wpi.c:514: ic->ic_update_mcast =3D wpi_update_mcast; dev/usb/wlan/if_rsu.c:596: ic->ic_update_mcast =3D rsu_update_mcast; dev/usb/wlan/if_upgt.c:354: ic->ic_update_mcast =3D upgt_update_mcast; dev/usb/wlan/if_zyd.c:401: ic->ic_update_mcast =3D zyd_update_mcast; dev/usb/wlan/if_urtw.c:902: ic->ic_update_mcast =3D urtw_update_mcast; dev/usb/wlan/if_run.c:832: ic->ic_update_mcast =3D run_update_mcast; dev/usb/wlan/if_uath.c:451: ic->ic_update_mcast =3D uath_update_mcast; dev/usb/wlan/if_rum.c:573: ic->ic_update_mcast =3D rum_update_mcast; dev/mwl/if_mwl.c:473: ic->ic_update_mcast =3D mwl_update_mcast; dev/if_ndis/if_ndis.c:929: ic->ic_update_mcast =3D ndis_update_mcast; dev/iwn/if_iwn.c:672: ic->ic_update_mcast =3D iwn_update_mcast; dev/ath/if_ath.c:1304: ic->ic_update_mcast =3D ath_update_mcast; dev/rtwn/if_rtwn.c:296: ic->ic_update_mcast =3D rtwn_update_mcast; dev/wtap/if_wtap.c:662: ic->ic_update_mcast =3D wtap_update_mcast; dev/otus/if_otus.c:759: ic->ic_update_mcast =3D otus_update_mcast; net80211/ieee80211_ddb.c:636: DB_PRINTSYM("\t", "ic_update_mcast", ic->ic_update_mcast); net80211/ieee80211_var.h:303: void=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20 (*ic_update_mcast)(struct ieee80211com *); net80211/ieee80211_proto.c:1373: ic->ic_update_mcast(ic); net80211/ieee80211.c:349: ic->ic_update_mcast =3D null_update_mcast; wildfire:/usr/src/sys 115 ### ->grep -Rn ic_update_promisc * dev/ral/rt2560.c:293: ic->ic_update_promisc =3D rt2560_update_promisc; dev/ral/rt2860.c:339: ic->ic_update_promisc =3D rt2860_update_promisc; dev/ral/rt2661.c:300: ic->ic_update_promisc =3D rt2661_update_promisc; dev/bwn/if_bwn.c:817: ic->ic_update_promisc =3D bwn_update_promisc; dev/wi/if_wi.c:436: ic->ic_update_promisc =3D wi_update_promisc; dev/wpi/if_wpi.c:513: ic->ic_update_promisc =3D wpi_update_promisc; dev/usb/wlan/if_rsu.c:595: ic->ic_update_promisc =3D rsu_update_promis= c; dev/usb/wlan/if_ural.c:485: ic->ic_update_promisc =3D ural_update_promi= sc; dev/usb/wlan/if_zyd.c:402: ic->ic_update_promisc =3D zyd_update_mcast; dev/usb/wlan/if_urtw.c:901: ic->ic_update_promisc =3D urtw_update_promi= sc; dev/usb/wlan/if_run.c:835: ic->ic_update_promisc =3D run_update_promis= c; dev/usb/wlan/if_uath.c:452: ic->ic_update_promisc =3D uath_update_promi= sc; dev/usb/wlan/if_rum.c:561: ic->ic_update_promisc =3D rum_update_promis= c; dev/mwl/if_mwl.c:474: ic->ic_update_promisc =3D mwl_update_promisc; dev/if_ndis/if_ndis.c:930: ic->ic_update_promisc =3D ndis_update_promi= sc; dev/iwn/if_iwn.c:671: ic->ic_update_promisc =3D iwn_update_promisc; dev/ath/if_ath.c:1305: ic->ic_update_promisc =3D ath_update_promisc; dev/rtwn/if_rtwn.c:295: ic->ic_update_promisc =3D rtwn_update_promisc; dev/wtap/if_wtap.c:663: ic->ic_update_promisc =3D wtap_update_promisc; dev/otus/if_otus.c:760: ic->ic_update_promisc =3D otus_update_mcast; net80211/ieee80211_ddb.c:637: DB_PRINTSYM("\t", "ic_update_promis= c", ic->ic_update_promisc); net80211/ieee80211_var.h:305: void=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20 (*ic_update_promisc)(struct ieee80211com *); net80211/ieee80211_proto.c:1381: ic->ic_update_promisc(ic); net80211/ieee80211.c:350: ic->ic_update_promisc =3D null_update_promi= sc; wildfire:/usr/src/sys 116 ### ->grep -Rn ic_update_chw * dev/usb/wlan/if_rsu.c:601: ic->ic_update_chw =3D rsu_update_chw; dev/ath/if_ath.c:1329: ic->ic_update_chw =3D ath_update_chw; dev/rtwn/if_rtwn.c:287: ic->ic_update_chw =3D rtwn_update_chw; dev/otus/if_otus.c:763: ic->ic_update_chw =3D otus_update_chw; net80211/ieee80211_var.h:371: void (*ic_update_chw)(st= ruct ieee80211com *); net80211/ieee80211_proto.c:1401: ic->ic_update_chw(ic); net80211/ieee80211.c:351: ic->ic_update_chw =3D null_update_chw; wildfire:/usr/src/sys 117 ### -> I don't know what the affect of not having the various callback functions a= re, or even if they are required for certain drivers. What I do know is that t= his is annoying and it messes up the console display (I just use a syscons cons= ole, no X.) when I'm using vi or something.
