           Summary: conntrack returns src, dst, dport and sport all zeroed
           Product: libnfnetlink
           Version: unspecified
          Platform: i386
        OS/Version: other
            Status: NEW
          Severity: major
          Priority: P1

Dear Sirs

I read bugzilla ID 548 and found this not related to that one.

Environment
  Slackware 12.0
  Kernel 2.6.27.7 SMP PREEMPT
  libnetfilter_conntrack-0.0.100 (configure --prefix=/usr;make;make install)
  conntrack-tools-0.9.13 (configure --prefix=/usr;make;make install)
  libnfnetlink-1.0.0 (configure --prefix=/usr;make;make install)

Also tried yesterday's daily-build of libnfnetlink, libnetfilter_conntrack
and
conntrack-tools. Same result. 

Could you give me some ideas what can be wrong?

"cat /proc/net/ip_conntrack" looks good. 

"conntrack" output is like this:

root at newquark:~# conntrack -L

udp      17 9 src=0.0.0.0 dst=0.0.0.0 sport=0 dport=0 packets=1 bytes=147 \
src=0.0.0.0 dst=0.0.0.0 sport=0 dport=0 packets=1 bytes=48 mark=2 use=1

tcp      6 35384 src=0.0.0.0 dst=0.0.0.0 sport=0 dport=0 packets=8 bytes=1051 \
src=0.0.0.0 dst=0.0.0.0 sport=0 dport=0 packets=7 bytes=7300 [ASSURED] mark=2 \
use=1

... and hundreds of lines just like that.

Kernel options are:

/usr/src/linux# grep -i netfilter .config 
(XTABLES and "not set" options stripped out)
CONFIG_NETFILTER=y
CONFIG_NETFILTER_ADVANCED=y
CONFIG_NETFILTER_NETLINK=m

/usr/src/linux# grep -i conn .config
CONFIG_NF_CONNTRACK=y
CONFIG_NF_CONNTRACK_MARK=y
CONFIG_NF_CONNTRACK_EVENTS=y
CONFIG_NF_CONNTRACK_FTP=m
CONFIG_NETFILTER_XT_TARGET_CONNMARK=y
CONFIG_NETFILTER_XT_MATCH_CONNBYTES=y
CONFIG_NETFILTER_XT_MATCH_CONNLIMIT=y
CONFIG_NETFILTER_XT_MATCH_CONNMARK=y
CONFIG_NETFILTER_XT_MATCH_CONNTRACK=y
CONFIG_NF_CONNTRACK_IPV4=y
CONFIG_NF_CONNTRACK_PROC_COMPAT=y
CONFIG_NF_CONNTRACK_IPV6=y

/usr/src/linux# grep CT_ .config
CONFIG_NF_CT_ACCT=y
CONFIG_NF_CT_NETLINK=m

Regards

Ethy

I cannot reproduce this problem using a similar .config file. Could you post
your full .config?
