           Summary: Segmentation Fault using Hop Limit and ICMPV6-TYPE in
                    same rule
           Product: iptables
           Version: unspecified
          Platform: x86_64
        OS/Version: Debian GNU/Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: ip6tables
        AssignedTo: netfilter-buglog at lists.netfilter.org
        ReportedBy: fukawi2+netfilter at gmail.com
   Estimated Hours: 0.0


Trying to create a rule using both "--icmpv6-type" and "--hl-eq" results in a
Segmentation Fault:

# ip6tables -A tgt_ICMP6 -m hl ! --hl-eq 255 -p icmpv6 --icmpv6-type redirect
-j DROP
Segmentation fault

Replicated on both CentOS 6 (iptables-ipv6 1.4.7) and Debian 6 (iptables 1.4.8)
(Both x86_64)

Removing either argument lets the remaining criteria work:
# ip6tables -A tgt_ICMP6 -p icmpv6 --icmpv6-type redirect -j DROP
# ip6tables -A tgt_ICMP6 -m hl --hl-eq 255 -p icmpv6  -j DROP
#

Not sure what other information is relevant; Just let me know and I'll be happy
to provide :)
