[1.] One line summary of the problem:
When compiling pppoe as module and enable socket filtering, pppoe module
has unresolved symbols. Problem not solved by inserting ppp filter into
kernel.
[2.] Full description of the problem/report:
I tried to compile kernel 2.4.20 with pppoe as module(CONFIG_PPPOE) and
socket filtering(CONFIG_FILTER) enabled.
When inserting the module I get
/lib/modules/2.4.20/kernel/drivers/net/pppoe.o: unresolved symbol
unregister_pppox_proto_Rsmp_e0ff7a18
/lib/modules/2.4.20/kernel/drivers/net/pppoe.o: unresolved symbol

When compiling PPP filtering into the kernel, I get (when trying to load
ppp_generic)

This configuration is necessary if you want to run a machine that serves as
DHCP server and PPP router. This might be important.
[X.] Other notes, patches, fixes, workarounds:
System.map has sk_run_filter references. Strange...
