GPL-2.0-only OR GPL-3.0-only
* Wed Mar 25 2026 Reinhard Max <max@suse.com>
- boo#1257934, 4070a748.patch: Fix build with nettle 4.0.
* Sat Jan 24 2026 Frank Schreiner <FSchreiner@suse.com>
- update to 2.92
* Redesign the interaction between DNSSEC validation and per-domain
servers, specified as --server=/<domain>/<ip-address>. This should
just work in all cases now. If the normal chain-of-trust exists into
the delegated domain then whether the domain is signed or not, DNSSEC
validation will function normally. In the case the delegated domain
is an "overlay" on top of the global DNS and no NS and/or DS records
exist connecting it to the global dns, then if the domain is
unsigned the situation will be handled by synthesising a
proof-of-non-existence-of-DS for the domain and queries will be
answered unvalidated; this action will be logged. A signed domain
without chain-of-trust can be validated if a suitable trust-anchor
is provided using --trust-anchor. This change should be backwards
compatible for all existing working configurations; it extends the
space of possible configurations which are functional.
* Fix a couple of problems with DNSSEC validation and DNAME. One
could cause validation failure on correct domains, and the other
would fail to spot an invalid domain. Thanks to Graham Clinch
for spotting the problem.
* Add --log-queries=auth option to only log replies from the auth DNS
facility.
* Fix some edge-cases with domains and --address and --server. There
has been some regressions with this in previous releases. This change
fixes the priority order from lower to highest as:
- -address with a IPv4 or IPv6 address (as long as the query matches the type)
- -address with # for all-zeros, as long as the query is A or AAAA)
- -address with no address, which returns NXDOMAIN or NOERROR for all types.
- -server with address set to # to use the unqualified servers.
- -server with matching domain.
- -server without domain or from /etc/resolv.conf.
* Fix problems with ipset or nftset and TCP DNS transport. Previously
this was racy, and insertion of addresses could fail on a busy server
when DNS-over-TCP transport was involved.
* DNSSEC validation change for reverse lookups in RFC-1918 ranges and friends.
The large public DNS services seem not to return proof-of-nonexistence
for DS records at the start of RFC-1918 in-addr.arpa domains and the their
IPv6 equivalents. 10.in-addr.arpa, 168.192.in-addr.arpa etc.
Since dnsmasq already has an option which instructs it not bother
upstream servers with pointless queries about these address ranges,
namely --bogus-priv, we extend that to enable behaviour which allows
dnsmasq to assume that insecure NXDOMAIN replies for these domains
are expected and to assume that the domains are legitimately unsigned.
This behaviour only matters when some address range is directed to
another upstream server using --rev-server. In that case it allows
replies from that server to pass DNSSEC validation. Without such a
server configured, queries are never sent upstream so they are never
validated and the new behaviour is moot.
* Add support for leasequery to the dnsmasq DHCPv4 server.
This has to be specifically enabled with the --leasequery option.
Many thanks to JAXPORT, Jacksonville Port Authority for sponsoring
this enhancement to dnsmasq.
* Fix failure to cache PTR RRs when a reply contains more than one answer.
Thanks to Dmitry for spotting this.
* Add TFTP options windowsize (RFC 7440) and timeout (RFC 2349).
* Change the behaviour of the DHCPv6 server when a REBIND message
is received but no lease exists. Under these circumstances a new
lease is created _only_ when the --dhcp-authoritative option is
set. This matches the behavior of the DHCPv4 server.
* Add --dhcp-split-relay option. This makes a DHCPv4 relay which
is functional when client and server networks aren't mutually
route-able.
* Fix failure to add client MAC address to queries in TCP mode.
The options which cause dnsmasq to decorate a DNS query with the MAC
address on the originating client can fail when the query is sent
using TCP. Thanks to Bruno Ravara for spotting and
characterising this bug.
* Thu Aug 21 2025 Reinhard Max <max@suse.com>
- bsc#1247812: Fix a segfault when setting up supplementary groups,
but no username was specified.
* Sun May 18 2025 Gerald Chen <gerald_chen@foxmail.com>
- update to 2.91:
* Fix spurious "resource limit exceeded messages".
* Fix out-of-bounds heap read in order_qsort().
* Fix buffer overflow when configured lease-change script name
is too long.
* Improve behaviour in the face of non-responsive upstream TCP DNS
servers. Without shorter timeouts, clients are blocked for too long
and fail with their own timeouts.
* Set --fast-dns-retries by default when doing DNSSEC. A single
downstream query can trigger many upstream queries. On an
unreliable network, there may not be enough downstream retries
to ensure that all these queries complete.
* Improve behaviour in the face of truncated answers to queries
for DNSSEC records. Getting these answers by TCP doesn't now
involve a faked truncated answer to the downstream client to
force it to move to TCP. This improves performance and robustness
in the face of broken clients which can't fall back to TCP.
* No longer remove data from truncated upstream answers. If an
upstream replies with a truncated answer, but the answer has some
RRs included, return those RRs, rather than returning and
empty answer.
* Fix handling of EDNS0 UDP packet sizes.
* Modify the behaviour of --synth-domain for IPv6.
* Fix broken dhcp-relay on *BSD.
* Add --dhcp-option-pxe config. This acts almost exactly like
- -dhcp-option except that the defined option is only sent when
replying to PXE clients. More importantly, these options are sent
in reply PXE clients when dnsmasq in acting in PXE proxy mode. In
PXE proxy mode, the set of options sent is defined by the PXE standard
and the normal set of options is not sent. This config allows arbitrary
options in PXE-proxy replies. A typical use-case is to send option
175 to iPXE.
* Support PXE proxy-DHCP and DHCP-relay at the same time.
* Fix erroneous "DNSSEC validated" state with non-DNSSEC
upstream servers.
* Handle queries with EDNS client subnet fields better. If dnsmasq
is configured to add an EDNS client subnet to a query, it is careful
to suppress use of the cache, since a cached answer may not be valid
for a query with a different client subnet. Extend this behaviour
to queries which arrive a dnsmasq already carrying an EDNS client
subnet.
* Handle DS queries to auth zones. When dnsmasq is configured to
act as an authoritative server and has an authoritative zone
configured, and receives a query for that zone _as_forwarder_
it answers the query directly rather than forwarding it. This
doesn't affect the answer, but it saves dnsmasq forwarding the
query to the recursor upstream, which then bounces it back to dnsmasq
in auth mode. The exception should be when the query is for the root
of zone, for a DS RR. The answer to that has to come from the parent,
via the recursor, and will typically be a proof-of-non-existence
since dnsmasq doesn't support signed zones. This patch suppresses
local answers and forces forwarding to the upstream recursor for such
queries. It stops breakage when a DNSSEC validating client makes
queries to dnsmasq acting as forwarder for a zone for which it is
authoritative.
* Implement "DNS-0x20 encoding", for extra protection against
reply-spoof attacks. Since DNS queries are case-insensitive,
it's possible to randomly flip the case of letters in a query
and still get the correct answer back.
* Fix a long-standing problem when two queries which are identical
in every repect _except_ case, get combined by dnsmasq. If
dnsmasq gets eg, two queries for example.com and Example.com
in quick succession it will get the answer for example.com from
upstream and send that answer to both requestors. This means that
the query for Example.com will get an answer for example.com, and
in the modern DNS, that answer may not be accepted.

* Mon Feb 06 2023 Paolo Stivanin <info@paolostivanin.com>
- update to 2.89:
* Fix bug introduced in 2.88 (commit fe91134b) which can result
in corruption of the DNS cache internal data structures and
logging of "cache internal error". This has only been seen
in one place in the wild, and it took considerable effort
to even generate a test case to reproduce it, but there's
no way to be sure it won't strike, and the effect is to break
the cache badly. Installations with DNSSEC enabled are more
likely to see the problem, but not running DNSSEC does not
guarantee that it won't happen. Thanks to Timo van Roermund
for reporting the bug and for his great efforts in chasing
it down. (boo#1207174)
