[1.] One line summary of the problem:
2.3.99-pre3 missing symbol tcp_v4_send_reset for ipt_REJECT
[2.] Full description of the problem/report:
I compiled the iptables and packet filtering support as modules. Appearently the ipt_REJECT module has an unmet dependence to tcp_v4_send_reset. AFAIU this symbol is exported by netsyms.c only for some rare cases (IPv6, http accelleration...), which are not enabled in my configuration.
[3.] Keywords:
modules, networking, kernel, 2.3.99-pre3, iptables, tcp_v4_send_reset
[4.] Kernel version (from /proc/version):
Linux version 2.3.99-pre3 (root@tk147051) (gcc version 2.95.2 20000220 (Debian GNU/Linux)) #1 Mon Mar 27 15:18:12 CEST 2000
[5.] Output
/lib/modules/2.3.99-pre3/ipv4/ipt_REJECT.o: unresolved symbol tcp_v4_send_reset /lib/modules/2.3.99-pre3/ipv4/ipt_REJECT.o: insmod /lib/modules/2.3.99-pre3/ipv4/ipt_REJECT.o failed /lib/modules/2.3.99-pre3/ipv4/ipt_REJECT.o: insmod ipt_REJECT failed
[7.] Environment
Probably not relevant, if someone can _not_ reproduce this problem, i am sorry, please tell me, i will provide information about the environment then.
Maybe all relevant info is:
[7.3.] Module information (from /proc/modules):
~# cat /proc/modules opl3 11400 2 opl3sa2 4208 2 ad1848 16432 2 [opl3sa2] mpu401 18928 2 [opl3sa2] sound 57484 0 [opl3 opl3sa2 ad1848 mpu401] soundcore 3588 7 [sound]
[7.5.] modutils:
insmod version 2.3.9 depmod version 2.3.9 modprobe version 2.3.9
[X.] Other notes, patches, fixes, workarounds:
[X.1.] A patch:
The following patch to linux/net/netsyms.c solves the problem, but i'm not enough a hacker to know what it does else... sorry.
343d342 < EXPORT_SYMBOL(tcp_v4_send_reset); 404a404,407 > > #if defined (CONFIG_IPV6_MODULE) || defined (CONFIG_KHTTPD) || defined (CONFIG_KHTTPD_MODULE) || defined (CONFIG_NETFILTER) > EXPORT_SYMBOL(tcp_v4_send_reset); > #endif
[X.2.] Disclaimer:
This is my second kernel bug report. I learned a lot about bug report style since then. If however it is still not satisfying, please tell me.
I tried to find out if someone else has already reported this problem. I am sorry if so. I also did not check unofficial patches.
Thanks Leonard
