2c59473 File logic bug in cache-marshalling code. Introduced a couple of commits back.
cc921df Remove nested struct/union in cache records and all_addr.
ab194ed Futher address union tidying.
65a01b7 Tidy address-union handling: move class into explicit argument.
bde4647 Tidy all_addr union, merge log and rcode fields.
e7bfd55 Alter DHCP address selection after DECLINE in consec-addr mode. Avoid offering the same address after a recieving a DECLINE message to stop an infinite protocol loop. This has long been done in default address allocation mode: this adds similar behaviour when allocaing addresses consecutively.

The most relevant fix for openwrt is 18eac67 (& my own local f52bb5b
which fixes a missing bracket silly) To quote the patch:

It is possible for a config entry to have one address family specified by a
dhcp-host directive and the other added from /etc/hosts. This is especially
common on OpenWrt because it uses odhcpd for DHCPv6 and IPv6 leases are
imported into dnsmasq via a hosts file.

To handle this case there need to be separate *_HOSTS flags for IPv4 and IPv6.
Otherwise when the hosts file is reloaded it will clear the CONFIG_ADDR(6) flag
which was set by the dhcp-host directive.

Kevin Darbyshire-Bryant 8c0f6a010a dnsmasq: follow upstream dnsmasq pre-v2.81 v2
Backport upstream commits.  Most interesting 122392e which changes how
SERVFAIL is handled especially in event of genuine server down/failure
scenarios with multiple servers.  a799ca0 also interesting in that
answered received via TCP are now cached, DNSSEC typically using TCP
meant until now answers weren't cached, hence reducing performance.

59e4703 Free config file values on parsing errors.
48d12f1 Remove the NO_FORK compile-time option, and support for uclinux.
122392e Revert 68f6312d4bae30b78daafcd6f51dc441b8685b1e
3a5a84c Fix Makefile lines generating UBUS linker config.
24b8760 Do not rely on dead code elimination, use array instead. Make options bits derived from size and count. Use size of option bits and last supported bit in computation. No new change would be required when new options are added. Just change OPT_LAST constant.
6f7812d Fix spurious AD flags in some DNS replies from local config.
cbb5b17 Fix logging in cf5984367bc6a949e3803a576512c5a7bc48ebab
cf59843 Don't forward *.bind/*.server queries upstream
ee87504 Remove ability to compile without IPv6 support.
a220545 Ensure that AD bit is reset on answers from --address=/<domain>/<address>.
a799ca0 Impove cache behaviour for TCP connections.

Along with an additional patch to fix compilation without DHCPv6, sent
upstream.

I've been running this for aaaages without obvious issue hence brave
step of opening to wider openwrt community.
