The following is an artifact in f_rndis.c that is present because of the USB gadget refactoring 679 rndis_set_param_medium(rndis->config, NDIS_MEDIUM_802_3, 0); 680 rndis_set_host_mac(rndis->config, rndis->ethaddr); 681 682 #if 0 683 // FIXME 684 if (rndis_set_param_vendor(rndis->config, vendorID, 685 manufacturer)) 686 goto fail0; 687 #endif 688 689 /* NOTE: all that is done without knowing or caring about 690 * the network link ... which is unavailable to this code 691 * until we're activated via set_alt(). The bad news is that I'm hitting an oops because of it. Newer versions of the windows rndis driver never seem to call OID_GEN_VENDOR_DESCRIPTION so this isn't a problem. However, older versions of XP SP2 and earlier machines still call this, and since the vendor string is never set in rndis_per_dev_params(rndis.c) the kernel ends up SEGV'ing by accessing the null pointer for the vendor string. I played around with this for about 3-4 hours yesterday trying to get the vendorID and manufacturer in some reasonable manner, but could not find a way to backtrack to them. Any suggestions to help me fix it? or even better solutions? :) I have plenty of boxes that are oops'ing so I can test solutions as needed. Eugene T.
