- jsc#SLE-17936: Sync this state from Factory to SLE-15-SP1.
- SLE bugs that got fixed upstream between 2.79 and 2.86, but for
which we need to keep references when syncing:
* bsc#1176076: dnsmasq-servfail.patch
* bsc#1156543: dnsmasq-siocgstamp.patch
* bsc#1138743: dnsmasq-cache-size.patch
* bsc#1076958: CVE-2017-15107, dnsmasq-CVE-2017-15107.patch
* bsc#1180914: Open inotify socket only when used.
* removed dnsmasq-dnspooq.patch
- bsc#1173646: Set --local-service by default.
- Update to 2.86:
* Handle DHCPREBIND requests in the DHCPv6 server code.
* Fix bug which caused dnsmasq to lose track of processes forked
to handle TCP DNS connections under heavy load.
* Major rewrite of the DNS server and domain handling code. This
should be largely transparent, but it drastically improves
performance and reduces memory foot-print when configuring
large numbers of domains.
* Revise resource handling for number of concurrent DNS queries.
* Improve efficiency of DNSSEC.
* Connection track mark based DNS query filtering.
* Allow smaller than 64 prefix lengths in synth-domain, with
caveats.
--synth-domain=1234:4567::/56,example.com is now valid.
* Make domains generated by --synth-domain appear in replies
when in authoritative mode.
* Ensure CAP_NET_ADMIN capability is available when conntrack
is configured.
* When --dhcp-hostsfile --dhcp-optsfile and --addn-hosts are

within that directory are read (alphabetical order of filename).
- Added hardening to systemd service(s) (bsc#1181400).
OBS-URL: https://build.opensuse.org/package/show/network/dnsmasq?expand=0&rev=137
* Fix problem with DNS retries in 2.83/2.84.
* Tweak sort order of tags in get-version.
* Avoid treating a --dhcp-host which has an IPv6 address as
eligible for use with DHCPv4 on the grounds that it has
no address, and vice-versa.
* Add --dynamic-host option: A and AAAA records which take their
network part from the network of a local interface. Useful
for routers with dynamically prefixes.
* Teach --bogus-nxdomain and --ignore-address to take an IPv4
subnet.
* CVE-2021-3448, bsc#1183709: Use random source ports where
possible if source addresses/interfaces in use.
* Change the method of allocation of random source ports for DNS.
* Scale the size of the DNS random-port pool based on the
value of the --dns-forward-max configuration.
* Tweak TFTP code to check sender of all received packets, as
specified in RFC 1350 para 4.

- Update to 2.83:
* bsc#1177077: Fixed DNSpooq vulnerabilities
* Use the values of --min-port and --max-port in outgoing
TCP connections to upstream DNS servers.
* Fix a remote buffer overflow problem in the DNSSEC code.
Any dnsmasq with DNSSEC compiled in and enabled is vulnerable
to this, referenced by CVE-2020-25681, CVE-2020-25682,
CVE-2020-25683 CVE-2020-25687.
* Be sure to only accept UDP DNS query replies at the address
from which the query was originated. This keeps as much
entropy in the {query-ID, random-port} tuple as possible, to
help defeat cache poisoning attacks. Refer: CVE-2020-25684.
* Use the SHA-256 hash function to verify that DNS answers
received are for the questions originally asked. This replaces
the slightly insecure SHA-1 (when compiled with DNSSEC) or
the very insecure CRC32 (otherwise). Refer: CVE-2020-25685
* Handle multiple identical near simultaneous DNS queries better.
Previously, such queries would all be forwarded independently.
This is, in theory, inefficent but in practise not a problem,
_except_ that is means that an answer for any of the forwarded
queries will be accepted and cached.
An attacker can send a query multiple times, and for each
repeat, another {port, ID} becomes capable of accepting the
answer he is sending in the blind, to random IDs and ports.
The chance of a succesful attack is therefore multiplied by the
number of repeats of the query. The new behaviour detects
repeated queries and merely stores the clients sending repeats
so that when the first query completes, the answer can be sent
to all the clients who asked. Refer: CVE-2020-25686.

- Update to 2.82:
* Improve behaviour in the face of network interfaces which come
and go and change index.
* Convert hard startup failure on NETLINK_NO_ENOBUFS under
qemu-user to a warning.
* Allow IPv6 addresses ofthe form [::ffff:1.2.3.4] in
--dhcp-option.
* Fix crash under heavy TCP connection load introduced in 2.81.
* Change default lease time for DHCPv6 to one day.
* Alter calculation of preferred and valid times in router
advertisements, so that these do not have a floor applied of
the lease time in the dhcp-range if this is not explicitly
specified and is merely the default.
- Reformat spec file with spec-cleaner

- Update to 2.81:
* Improve cache behaviour for TCP connections
* Remove the NO_FORK compile-time option, and support for uclinux
* Fix line-counting when reading /etc/hosts and friends
* Fix bug in DNS non-terminal code, added in 2.80, which could
sometimes cause a NODATA rather than an NXDOMAIN reply.
* Support TCP-fastopen (RFC-7413) on both incoming and
outgoing TCP connections, if supported and enabled in the OS.
* Improve kernel-capability manipulation code under Linux
* Add --shared-network config. This enables allocation of addresses
by the DHCP server in subnets where the server (or relay) does not
have an interface on the network in that subnet. Many thanks to
kamp.de for sponsoring this feature.
* Fix broken contrib/lease_tools/dhcp_lease_time.c. A packet
validation check got borked in commit 2b38e382 and release 2.80.
Thanks to Tomasz Szajner for spotting this.
* Fix compilation against nettle version 3.5 and later.
* Fix spurious DNSSEC validation failures when the auth section
of a reply contains unsigned RRs from a signed zone,
with the exception that NSEC and NSEC3 RRs must always be signed.
Thanks to Tore Anderson for spotting and diagnosing the bug.
* Add --dhcp-ignore-clid. This disables reading of DHCP client
identifier option (option 61), so clients are only identified by
MAC addresses.
* Fix a bug which stopped --dhcp-name-match from working when a hostname
is supplied in --dhcp-host. Thanks to James Feeney for spotting this.
* Fix bug which caused very rarely caused zero-length DHCPv6 packets.
Thanks to Dereck Higgins for spotting this.
* Add --tftp-single-port option.
* Enhance --conf-dir to load files in a deterministic order
* Add filtering by tag of --dhcp-host directives
* Remove DSA signature verification from DNSSEC, as specified in
RFC 8624
* Add --script-on-renewal option.

- Drop use of $FIRST_ARG in .spec
The use of $FIRST_ARG was probably required because of the
%service_* rpm macros were playing tricks with the shell positional
parameters. This is bad practice and error prones so let's assume
that no macros should do that anymore and hence it's safe to assume
that positional parameters remains unchanged after any rpm macro
call.
