$(call Package/iptables/Module, +kmod-ipt-cluster)
TITLE:=Match cluster extension
endef
define Package/iptables-mod-cluster/description
iptables extensions for matching cluster.
Netfilter (IPv4/IPv6) module for matching cluster
This option allows you to build work-load-sharing clusters of
network servers/stateful firewalls without having a dedicated
load-balancing router/server/switch. Basically, this match returns
true when the packet must be handled by this cluster node. Thus,
all nodes see all packets and this match decides which node handles
what packets. The work-load sharing algorithm is based on source
address hashing.
This module is usable for ipv4 and ipv6.
If you select it, it enables kmod-ipt-cluster.
see `iptables -m cluster --help` for more information.

Subject: [PATCH] iptables: connmark - add set-dscpmark option for openwrt
Naive user space front end to xt_connmark 'setdscp' option.
iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000
This version has a hack to support a backport to 4.14

Subject: treewide: use uint* instead of u_int*
Gcc complains about missing types. Some commits introduced u_int* instead
of uint*. Use uint treewide.
Fixes errors in the form of:
In file included from xtables-legacy-multi.c:5:
xshared.h:83:56: error: unknown type name 'u_int16_t'; did you mean 'uint16_t'?
83 | set_option(unsigned int *options, unsigned int option, u_int16_t *invflg,
| ^~~~~~~~~
| uint16_t
make[6]: *** [Makefile:712: xtables_legacy_multi-xtables-legacy-multi.o] Error 1
Avoid libipq API breakage by adjusting libipq.h include accordingly. For
arpt_mangle.h kernel uAPI header, apply same change as in kernel commit
e91ded8db5747 ("uapi: netfilter_arp: use __u8 instead of u_int8_t").

Subject: Revert "fix build for missing ETH_ALEN definition"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This reverts commit c5d9a723b5159a28f547b577711787295a14fd84 as it broke
compiling against musl libc. Might be a bug in the latter, but for the
time being try to please both by avoiding the include and instead
defining ETH_ALEN if unset.
While being at it, move netinet/ether.h include up.
Fixes: 1bdb5535f561a ("libxtables: Extend MAC address printing/parsing support")

Subject: libxtables: Unexport init_extensions*() declarations
The functions are used for static builds to initialize extensions after
libxtables init. Regular library users should not need them, but the
empty declarations introduced in #else case (and therefore present in
user's env) may clash with existing symbol names.
Avoid problems and guard the whole block declaring the function
prototypes and mangling extensions' _init functions by XTABLES_INTERNAL.
Reported-by: Nick Hainke <vincent@systemli.org>
