setup.phone and setup.eazmsn are 32 character buffers. rcvmsg.msg_data.byte_array is a 48 character buffer. sc_adapter[card]->channel[rcvmsg.phy_link_no - 1].dn is 50 chars. The rcvmsg struct comes from the memcpy_fromio() in receivemessage(). I guess that means it's data off the wire. I'm not very familiar with this code but I don't see any reason to assume these strings are NULL terminated. Also it's weird that "dn" in a 50 character buffer but we only seem to use 32 characters. In drivers/isdn/sc/scioc.h, "dn" is only a 49 character buffer. So potentially there is still an issue there. The important thing for now is to prevent the memory corruption.
