While trying to build the kernel several symbols needed by network.a fail to get defined due to inlining difficulties ? Here is an example, notice the problem with skb_put:
======================================================================= gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O3 -fomit-frame-pointer -pipe -fno-strength-reduce -m486 -DCPU=486 -Winline -c -o test.o af_packet.c /usr/src/linux/include/linux/skbuff.h: In function `skb_put': In file included from /usr/src/linux/include/linux/netdevice.h:158, from af_packet.c:52: /usr/src/linux/include/linux/skbuff.h:453: warning: function with label addresses taken cannot inline /usr/src/linux/include/linux/skbuff.h: In function `skb_push': /usr/src/linux/include/linux/skbuff.h:467: warning: function with label addresses taken cannot inline /usr/src/linux/include/linux/skbuff.h: In function `__nlmsg_put': /usr/src/linux/include/linux/skbuff.h:453: warning: can't inline call to `skb_put' In file included from /usr/src/linux/include/linux/rtnetlink.h:5, from /usr/src/linux/include/net/route.h:29, from /usr/src/linux/include/net/ip.h:32, from af_packet.c:56: /usr/src/linux/include/linux/netlink.h:135: warning: called from here /usr/src/linux/include/linux/skbuff.h: In function `ip_finish_output': /usr/src/linux/include/linux/skbuff.h:467: warning: can't inline call to `skb_push' In file included from af_packet.c:56: /usr/src/linux/include/net/ip.h:151: warning: called from here =========================================================================
In the end when trying to link the kernel you get: packet.o = af_packet.o
net/network.a(netlink.o)(.text+0xac4): more undefined references to `skb_put' follow net/network.a(packet.o): In function `packet_rcv_spkt': packet.o(.text+0x37): undefined reference to `skb_push' net/network.a(packet.o): In function `packet_sendmsg_spkt': packet.o(.text+0x1fd): undefined reference to `skb_put' net/network.a(packet.o): In function `packet_rcv': packet.o(.text+0x303): undefined reference to `skb_push' net/network.a(packet.o): In function `packet_sendmsg': packet.o(.text+0x501): undefined reference to `skb_put' make: *** [vmlinux] Error 1
