2.4.22 PPP filtering for ISDN

2.4.22 PPP filtering for ISDN

[Frank Elsner]

When trying to compile kernel 2.4.22 (from kernel.org) with 
PPP filtering for ISDN enabled by "CONFIG_IPPP_FILTER=y" I get 

    ld -m elf_i386 -T /usr/src/linux-2.4.22/arch/i386/vmlinux.lds -e stext arch/i386

ilter' follow
make: *** [vmlinux] Error 1

Relevant config options are set as follows:

# ISDN subsystem
CONFIG_ISDN=y
CONFIG_ISDN_BOOL=y
CONFIG_ISDN_PPP=y
CONFIG_ISDN_PPP_VJ=y
CONFIG_ISDN_MPP=y
CONFIG_ISDN_PPP_BSDCOMP=m
CONFIG_ISDN_PPP_LZSCOMP=m          

Where is the problem located ?

You are missing CONFIG_FILTER=y/m. This is a config bug which is already 
fixed
in .23-preX, it is not possible to select CONFIG_IPPP_FILTER without 
selecting
CONFIG_FILTER anymore.
