Hi! The Netfilter project proudly presents: libnetfilter_conntrack 1.0.9 This release comes with the new nfct_nlmsg_build_filter() function that allows to add metadata for kernel-side filtering of conntrack entries during conntrack table dump. The nfct_query() API supports the new NFCT_Q_FLUSH_FILTER argument, it allows to flush only ipv4 or ipv6 entries from the connection tracking table. nfct_snprint family of functions have been updated. SCTP conntrack entries now support 'heartbeat sent/acked' state. Entries offloaded to hardware include '[HW_OFFLOAD]' in the formatted output string. Notable bugs fixed with this release include: Fix buffer overflows and out-of-bounds accesses in the nfct_snprintf() functions. nfct_nlmsg_build() did not work for ICMP flows unless all ICMP attributes were set in the reply tuple too, this affected the 'conntrack' tool where updates (e.g. setting the conntrack mark to a different value) of ICMP flows would not work. See ChangeLog that comes attached to this email for more details. You can download it from: https://www.netfilter.org/projects/libnetfilter_conntrack/downloads.html
