When compiling Gentoo-sources 2.4.20-r7, during "make bzImage", the output ends with: --------------------------------------------------------- gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon-mp -nostdinc -iwithprefix include -DKBUILD_BASENAME=ipt_unclean -c -o ipt_unclean.o ipt_unclean.c gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon-mp -nostdinc -iwithprefix include -DKBUILD_BASENAME=ipt_string -c -o ipt_string.o ipt_string.c ipt_string.c: In function `search_sublinear': ipt_string.c:53: warning: subscript has type `char' ipt_string.c:78: warning: subscript has type `char' gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon-mp -nostdinc -iwithprefix include -DKBUILD_BASENAME=ipt_tcpmss -c -o ipt_tcpmss.o ipt_tcpmss.c gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon-mp -nostdinc -iwithprefix include -DKBUILD_BASENAME=ipt_stealth -c -o ipt_stealth.o ipt_stealth.c gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon-mp -nostdinc -iwithprefix include -DKBUILD_BASENAME=ipt_realm -c -o ipt_realm.o ipt_realm.c ipt_realm.c: In function `match': ipt_realm.c:29: structure has no member named `tclassid' make[3]: *** [ipt_realm.o] Error 1 make[3]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r7/net/ipv4/netfilter' make[2]: *** [first_rule] Error 2 make[2]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r7/net/ipv4/netfilter' make[1]: *** [_subdir_ipv4/netfilter] Error 2 make[1]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r7/net' make: *** [_dir_net] Error 2 cwithprefix include -DKBUILD_BASENAME=ipt_string -c -o ipt_string.o ipt_string. ipt_string.c: In function `search_sublinear': gcc: ipt_string.c: No such file or directory gcc: no input files --------------------------------------------------- The system itself is stable and can compile all day. This error appears in the same place every time. I will post more info if I find anything worth noting. Reproducible: Always Steps to Reproduce: 1. Configure a Gentoo-sources kernel, probably one with all of the non-experimental IPfilter options 2. Compile it. 3. Profit!!! Actual Results: GCC error as above, no kernel Expected Results: Popped a kernel out.

Manually add "CONFIG_NET_CLS_ROUTE=y" to your .config and see if things work. You might need to do a 'make clean dep' before doing 'make bzImage'

Didnt help in my case, i did: 1. inserted row to /usr/src/linux/.config CONFIG_NET_CLS_ROUTE=y 2. make clean dep 3. make bzImage -> completes successfully 4. make modules -> gcc -D__KERNEL__ -I/usr/src/linux-2.4.20-gentoo-r7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon -DMODULE -DMODVERSIONS -include /usr/src/linux-2.4.20-gentoo-r7/include/linux/modversions.h -nostdinc -iwithprefix include -DKBUILD_BASENAME=ipt_realm -c -o ipt_realm.o ipt_realm.c ipt_realm.c: In function `match': ipt_realm.c:29: structure has no member named `tclassid' make[2]: *** [ipt_realm.o] Error 1 make[2]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r7/net/ipv4/netfilter' make[1]: *** [_modsubdir_ipv4/netfilter] Error 2 make[1]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r7/net' make: *** [_mod_net] Error 2
Confirmed. Resolution is to enable the following in networking options:- [ Note that if you enable these as *non-modules* you would have to recompile your kernel and install it, enabling these as modules is recommended ] Networking Options -> QoS and/or fair queuing -> Packet Classifier API -> Routing table based classifier... I'll add a #warning to the ipt_realm.c file to enforce this.
In CVS...
