linux-4.1.15_CVE-2018-5873

HiSax is a Linux hardware-level driver for passive ISDN cards with Siemens chipset (ISAC_S 2085/2086/2186, HSCX SAB 82525). It is based on the Teles driver from Jan den Ouden. It is meant to be used with isdn4linux, an ISDN link-level module for Linux written by Fritz Elfert.

If you know other passive cards with the Siemens chipset, please let me know. You can combine any card, if there is no conflict between the resources (io, mem, irq).

Configuring the driver

The HiSax driver can either be built directly into the kernel or as a module. It can be configured using the command line feature while loading the kernel with LILO or LOADLIN or, if built as a module, using insmod/modprobe with parameters. There is also some config needed before you compile the kernel and/or modules. It is included in the normal "make [menu]config" target at the kernel. Don't forget it, especially to select the right D-channel protocol.

Please note: In older versions of the HiSax driver, all PnP cards needed to be configured with isapnp and worked only with the HiSax driver used as a module.

In the current version, HiSax will automatically use the in-kernel ISAPnP support, provided you selected it during kernel configuration (CONFIG_ISAPNP), if you don't give the io=, irq= command line parameters.

The affected card types are: 4,7,12,14,19,27-30

a) when built as a module

insmod/modprobe hisax.o
io=iobase irq=IRQ mem=membase type=card_type
protocol=D_channel_protocol id=idstring

or, if several cards are installed:

insmod/modprobe hisax.o
io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,...
type=card_type1,card_type2,...
protocol=D_channel_protocol1,D_channel_protocol2,...
id=idstring1%idstring2 ...

where "iobaseN" represents the I/O base address of the Nth card, "membaseN" the memory base address of the Nth card, etc.

The reason for the delimiter "%" being used in the idstrings is that "," won't work with the current modules package.

The parameters may be specified in any order. For example, the "io" parameter may precede the "irq" parameter, or vice versa. If several cards are installed, the ordering within the comma separated parameter lists must of course be consistent.

Only parameters applicable to the card type need to be specified. For example, the Teles 16.3 card is not memory-mapped, so the "mem" parameter may be omitted for this card. Sometimes it may be necessary to specify a dummy parameter, however. This is the case when there is a card of a different type later in the list that needs a parameter which the preceding card does not. For instance, if a Teles 16.0 card is listed after a Teles 16.3 card, a dummy memory base parameter of 0 must be specified for the 16.3. Instead of a dummy value, the parameter can also be skipped by simply omitting the value. For example: mem=,0xd0000. See example 6 below.

The parameter for the D-Channel protocol may be omitted if you selected the correct one during kernel config. Valid values are "1" for German 1TR6, "2" for EDSS1 (Euro ISDN), "3" for leased lines (no D-Channel) and "4" for US NI1. With US NI1 you have to include your SPID into the MSN setting in the form : for example (your phonenumber is 1234 your SPID 5678): AT&E1234:5678 on ttyI interfaces isdnctrl eaz ippp0 1234:5678 on network devices

The Creatix/Teles PnP cards use io1= and io2= instead of io= for specifying the I/O addresses of the ISAC and HSCX chips, respectively.
