Hi,
The following series contains Netfilter/IPVS updates for net-next:
1) Display netns inode in conntrack table full log, from lvxiafei.
2) Autoload nf_log_syslog in case no logging backend is available,
from Lance Yang.
3) Three patches to remove unused functions in x_tables, nf_tables and
conntrack. From Yue Haibing.
4) Exclude LEGACY TABLES on PREEMPT_RT: Add NETFILTER_XTABLES_LEGACY
to exclude xtables legacy infrastructure.
5) Restore selftests by toggling NETFILTER_XTABLES_LEGACY where needed.
From Florian Westphal.
6) Use CONFIG_INET_SCTP_DIAG in tools/testing/selftests/net/netfilter/config,
from Sebastian Andrzej Siewior.
7) Use timer_delete in comment in IPVS codebase, from WangYuli.
8) Dump flowtable information in nfnetlink_hook, this includes an initial
patch to consolidate common code in helper function, from Phil Sutter.
9) Remove unused arguments in nft_pipapo set backend, from Florian Westphal.
10) Return nft_set_ext instead of boolean in set lookup function,
from Florian Westphal.
11) Remove indirection in dynamic set infrastructure, also from Florian.
12) Consolidate pipapo_get/lookup, from Florian.
13) Use kvmalloc in nft_pipapop, from Florian Westphal.
14) syzbot reports slab-out-of-bounds in xt_nfacct log message,
fix from Florian Westphal.
15) Ignored tainted kernels in selftest nft_interface_stress.sh,
from Phil Sutter.
16) Fix IPVS selftest by disabling rp_filter with ipip tunnel device,
from Yi Chen.
