In diva_mnt_add_xdi_adapter() we do this:
strcpy (clients[id].drvName, tmp);
strcpy (clients[id].Dbg.drvName, tmp);
The "clients[id].drvName" is a 128 character buffer and
"clients[id].Dbg.drvName" was originally a 16 character buffer but I've
changed it to 128 as well. We don't actually use 128 characters but we
do use more than 16.
I don't see any reason for that change. The driver names here do not use
more than 16 characters and when filled, the length is checked anyway.
Please avoid changing the size of that structure.
drivers/isdn/hardware/eicon/debug.c diva_mnt_add_xdi_adapter()
874 sprintf (tmp, "ADAPTER:%d SN:%u-%d",
12345678 90123 45 67
That's a minimum 17 characters.
875 (int)logical,
876 serial & 0x00ffffff,
877 (byte)(((serial & 0xff000000) >> 24) + 1));
878 } else {
879 sprintf (tmp, "ADAPTER:%d SN:%u", (int)logical, serial);
880 }
this is tmp with a bigger size. It seems you are mixing the sizes of
drvName and tmp.
