-Subject: [PATCH] Change dhcp_release to use default address when no IP subnet
- matches
-
-Currently, dhcp_release will only send a 'fake' release
-when the address given is in the same subnet as an IP
-on the interface that was given.
-
-This doesn't work in an environment where dnsmasq is
-managing leases for remote subnets via a DHCP relay, as
-running dhcp_release locally will just cause it to
-silently exit without doing anything, leaving the lease
-in the database.
-
-Change it to use the default IP on the interface, as the
-dnsmasq source code at src/dhcp.c does, if no matching subnet
-IP is found, as a fall-back.  This fixes an issue we are
-seeing in certain Openstack deployments where we are using
-dnsmasq to provision baremetal systems in a datacenter.
-
-While using Dbus might have seemed like an obvious solution,
-because of our extensive use of network namespaces (which
-Dbus doesn't support), this seemed like a better solution
-than creating system.d policy files for each dnsmasq we
-might spawn and using --enable-dbus=$id in order to isolate
-messages to specific dnsmasq instances.

-Subject: [PATCH 2/4] Check destination of DNS UDP query replies.
-
-At any time, dnsmasq will have a set of sockets open, bound to
-random ports, on which it sends queries to upstream nameservers.
-This patch fixes the existing problem that a reply for ANY in-flight
-query would be accepted via ANY open port, which increases the
-chances of an attacker flooding answers "in the blind" in an
-attempt to poison the DNS cache. CERT VU#434904 refers.

-Subject: [PATCH 4/4] 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: CERT VU#434904.

-Subject: [PATCH] Move fd into frec_src, fixes
- 15b60ddf935a531269bb8c68198de012a4967156
-
-If identical queries from IPv4 and IPv6 sources are combined by the
-new code added in 15b60ddf935a531269bb8c68198de012a4967156 then replies
-can end up being sent via the wrong family of socket. The ->fd
-should be per query, not per-question.
-
-In bind-interfaces mode, this could also result in replies being sent
-via the wrong socket even when IPv4/IPV6 issues are not in play.
-
-(cherry picked from commit 04490bf622ac84891aad6f2dd2edf83725decdee)
-
-Fix for 12af2b171de0d678d98583e2190789e544440e02

-Subject: [PATCH] Fix sometimes missing DNSSEC RRs when DNSSEC validation not
- enabled.
-
-Dnsmasq does pass on the do-bit, and return DNSSEC RRs, irrespective
-of of having DNSSEC validation compiled in or enabled.
-
-The thing to understand here is that the cache does not store all the
-DNSSEC RRs, and dnsmasq doesn't have the (very complex) logic required
-to determine the set of DNSSEC RRs required in an answer. Therefore if
-the client wants the DNSSEC RRs, the query can not be answered from
-the cache. When DNSSEC validation is enabled, any query with the
-do-bit set is never answered from the cache, unless the domain is
-known not to be signed: the query is always forwarded. This ensures
-that the DNSEC RRs are included.
-
-The same thing should be true when DNSSEC validation is not enabled,
-but there's a bug in the logic.
-
-line 1666 of src/rfc1035.c looks like this
-
- if ((crecp->flags & (F_HOSTS | F_DHCP | F_CONFIG)) || !do_bit || !(crecp->flags & F_DNSSECOK))
-
-{ ...answer from cache ... }
-
-So local stuff (hosts, DHCP, ) get answered. If the do_bit is not set
-then the query is answered, and if the domain is known not to be
-signed, the query is answered.
-
-Unfortunately, if DNSSEC validation is not turned on then the
-F_DNSSECOK bit is not valid, and it's always zero, so the question
-always gets answered from the cache, even when the do-bit is set.
-
-This code should look like that at line 1468, dealing with PTR queries
-
-  if ((crecp->flags & (F_HOSTS | F_DHCP | F_CONFIG)) ||
-      !do_bit ||
-      (option_bool(OPT_DNSSEC_VALID) && !(crecp->flags & F_DNSSECOK)))
-
-where the F_DNSSECOK bit is only used when validation is enabled.

-Subject: [PATCH] Ignore routes in non-main tables
-
-Route lookup in Linux is bounded by `ip rules` as well
-as the contents of specific routing tables.  With the
-advent of vrf's(l3mdev's) non-default tables are regularly being
-used for routing purposes.
-
-dnsmasq listens to all route changes on the box and responds
-to each one with an event.  This is *expensive* when a full
-BGP routing table is placed into the linux kernel, moreso
-when dnsmasq is responding to events in tables that it will
-never actually need to respond to, since dnsmasq at this
-point in time has no concept of vrf's and would need
-to be programmed to understand them.  Help alleviate this load
-by reducing the set of data that dnsmasq pays attention to
-when we know there are events that are not useful at this
-point in time.

-    Optimise closing file descriptors.
-    
-    Dnsmasq needs to close all the file descriptors it inherits, for security
-    reasons. This is traditionally done by calling close() on every possible
-    file descriptor (most of which won't be open.) On big servers where
-    "every possible file descriptor" is a rather large set, this gets
-    rather slow, so we use the /proc/<pid>/fd directory to get a list
-    of the fds which are acually open.
-    
-    This only works on Linux. On other platforms, and on Linux systems
-    without a /proc filesystem, we fall back to the old way.

-Subject: [PATCH] Add DHCPv6 ntp-server (56) option handling.
-
-There was discussion in the past regarding DHCPv6 NTP server option
-which needs special subclassing per RFC5908.
-
-Patch adds support for unicast, multicast IPv6 address and for FQDN string,
-preserving possibly used (as suggested earlier) hex value.
-
-Unfortunately it's still not fully free from limitations - only address list or
-only fqdn value list is possible, not mixed due current
-state option parsing & flagging.

-When a request matching the clid or mac address is
-recieved the server will iterate over all candidate
-addresses until it find's one that is not already
-leased to a different clid/iaid and advertise
-this address.
-
-Using multiple reservations for a single host makes it
-possible to maintain a static leases only configuration
-which support network booting systems with UEFI firmware
-that request a new address (a new SOLICIT with a new IA_NA
-option using a new IAID) for different boot modes, for
-instance 'PXE over IPv6', and 'HTTP-Boot over IPv6'. Open
-Virtual Machine Firmware (OVMF) and most UEFI firmware
-build on the EDK2 code base exhibit this behaviour.

-Subject: [PATCH 1/1] Fix regression in s_config_in_context() method
-
-Prior to commit 137286e9baecf6a3ba97722ef1b49c851b531810
-a config would not be considered in context if:
-a) it has no address family flags set
-b) it has the address family flag of current context set
-
-Since above commit config is considered in context if the
-address family is the opposite of current context.
-
-The result is that a config with two dhcp-host records,
-one for IPv6 and another for IPv4 no longer works, for
-example with the below config the config with the IPv6
-address would be considered in context for a DHCP(v4)
-request.
- dhcp-host=52:54:00:bc:c3:fd,172.20.0.11,host2
- dhcp-host=52:54:00:bc:c3:fd,[fd12:3456:789a:1::aadd],host2
-
-This commit restores the previous behavior.

-Date: Wed, 17 Feb 2021 11:47:28 +0100
-Subject: [PATCH] Correct occasional --bind-dynamic synchronization break
-
-Request only one re-read of addresses and/or routes
-
-Previous implementation re-reads systemd addresses exactly the same
-number of time equal number of notifications received.
-This is not necessary, we need just notification of change, then re-read
-the current state and adapt listeners. Repeated re-reading slows netlink
-processing and highers CPU usage on mass interface changes.
-
-Continue reading multicast events from netlink, even when ENOBUFS
-arrive. Broadcasts are not trusted anyway and refresh would be done in
-iface_enumerate. Save queued events sent again.
-
-Remove sleeping on netlink ENOBUFS
-
-With reduced number of written events netlink should receive ENOBUFS
-rarely. It does not make sense to wait if it is received. It is just a
-signal some packets got missing. Fast reading all pending packets is required,
-seq checking ensures it already. Finishes changes by
-commit 1d07667ac77c55b9de56b1b2c385167e0e0ec27a.
-
-Move restart from iface_enumerate to enumerate_interfaces
-
-When ENOBUFS is received, restart of reading addresses is done. But
-previously found addresses might not have been found this time. In order
-to catch this, restart both IPv4 and IPv6 enumeration with clearing
-found interfaces first. It should deliver up-to-date state also after
-ENOBUFS.
-
-Read all netlink messages before netlink restart
-
-Before writing again into netlink socket, try fetching all pending
-messages. They would be ignored, only might trigger new address
-synchronization. Should ensure new try has better chance to succeed.
-
-Request sending ENOBUFS again
-
-ENOBUFS error handling was improved. Netlink is correctly drained before
-sending a new request again. It seems ENOBUFS supression is no longer
-necessary or wanted. Let kernel tell us when it failed and handle it a
-good way.

+Subject: [PATCH] Ensure search_servers domain is set on dnssec
+
+When dnssec validation is enabled the domain variable used when fetching
+dnssec key or domain were not properly initialized always. It were read
+anyway inside search_servers. Because it is changed only sometime, do
+not use its value on the end of function. domain can be NULL only at
+that point, use that value right away.
+
+Include also TCP.

+Subject: [PATCH] Fix bug in TCP process handling.
+
+Fix bug which caused dnsmasq to lose track of processes forked
+to handle TCP DNS connections under heavy load. The code
+checked that at least one free process table slot was
+available before listening on TCP sockets, but didn't take
+into account that more than one TCP connection could
+arrive, so that check was not sufficient to ensure that
+there would be slots for all new processes. It compounded
+this error by silently failing to store the process when
+it did run out of slots. Even when this bug is triggered,
+all the right things happen, and answers are still returned.
+Only under very exceptional circumstances, does the bug
+manifest itself: see
+https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2021q2/014976.html
+
+Thanks to Tijs Van Buggenhout for finding the conditions under
+which the bug manifests itself, and then working out
+exactly what was going on.
+
+(cherry picked from commit ad90eb075dfeeb1936e8bc0f323fcc23f89364d4)
