In nb_enum_if() in /usr/src/contrib/smbfs/lib/smb/nb_net.c, this code
traverses all of the net interfaces looking for broadcast addresses.
Of interest ifc.ifc_len is 524, but sizeof (struct ifreq) is 32?
Shouldn't the len be an integer multiple of the size of the struct?
I can find no documentation of these ioctl's. I looked at the bytes
returned by SIOCGIFCONF an it's clearly not what the libsmbfs code
expects, but I don't know what SIOCGIFCONF is really supposed to
return & the structure boundaries in the buffer aren't obvious.
if (ioctl(s, SIOCGIFCONF, &ifc) != 0) {
error = errno;
goto bad;
}
ifrqp = ifc.ifc_req;
ifcnt = ifc.ifc_len / sizeof(struct ifreq);
error = 0;
for (i = 0; i < ifcnt; i++, ifrqp++) {
if (ioctl(s, SIOCGIFFLAGS, ifrqp) != 0)
continue;
