* dnsmasq: backport latest pre2.81 patchesKevin Darbyshire-Bryant2019-01-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | f52bb5b fix previous commit 18eac67 Fix entries in /etc/hosts disabling static leases. f8c77ed Fix removal of DHCP_CLIENT_MAC options from DHCPv6 relay replies. 4bf62f6 Tidy cache_blockdata_free() 9c0d445 Fix e7bfd556c079c8b5e7425aed44abc35925b24043 to actually work. 2896e24 Check for not(DS or DNSKEY) in is_outdated_cname_pointer() a90f09d Fix crash freeing negative SRV cache entries. 5b99eae Cache SRV records. 2daca52 Fix typo in ra-param man page section. 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. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

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.

* dnsmasq: drop dnssec timestamp file patchKevin Darbyshire-Bryant2018-12-101-1/+1
| | | | | | | | | | | | Openwrt no longer uses and has not used since 5acfe55d71 Jun 2016 the timestamp file (/etc/dnsmasq.time) method of resolving the dnssec/ntp dnslookup chicken/egg problem, having used signals from ntp since that change.

* dnsmasq: add dhcp-ignore-names support - CERT VU#598349Kevin Darbyshire-Bryant2018-10-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | dnsmasq v2.80test8 adds the ability to ignore dhcp client's requests for specific hostnames. Clients claiming certain hostnames and thus claiming DNS namespace represent a potential security risk. e.g. a malicious host could claim 'wpad' for itself and redirect other web client requests to it for nefarious purpose. See CERT VU#598349 for more details. Some Samsung TVs are claiming the hostname 'localhost', it is believed not (yet) for nefarious purposes. /usr/share/dnsmasq/dhcpbogushostname.conf contains a list of hostnames in correct syntax to be excluded. e.g. dhcp-name-match=set:dhcp_bogus_hostname,localhost Inclusion of this file is controlled by uci option dhcpbogushostname which is enabled by default. To be absolutely clear, DHCP leases to these requesting hosts are still permitted, but they do NOT get to claim ownership of the hostname itself and hence put into DNS for other hosts to be confused/manipulate by.

* dnsmasq: don't use network functions at boottime (FS#1542)Hans Dedecker2018-07-171-1/+1
| | | | | | | | | | | | As dnsmasq is started earlier than netifd usage of network.sh functions at boottime will fail; therefore don't call at boottime the functions which construct the dhcp pool/relay info. As interface triggers are installed the dhcp pool/relay info will be constructed when the interface gets reported as up by netifd. At the same time also register interface triggers based on DHCP relay config. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

* dnsmasq: add specific interface procd triggershux2018-05-111-1/+1
| | | | | | | | | | | | | | | | | | Right now interface.update events are sent out by netifd upon interface state, route, address (lifetime), prefix lifetime changes. Dnsmasq is only interested in interface state changes and currently adds an interface trigger for all the "interface.*" events. In combination with commit 23bba9cb330, which triggers a SIGHUP signal to dnsmasq, IPv6 address/prefix lifetime changes on the wan will trigger dnsmasq reloads which can become frequent in case of shorter lifetimes. To avoid frequent dnsmasq reload, this patch adds specific interface triggers. During dnsmasq init it loops dhcp uci section; if the value of the ignore option is set to 0, then the corresponding interface trigger is not installed. Otherwise, if the ignore option value is 1, then procd_add_interface_trigger is called which adds the interface trigger. Signed-off-by: hux <xinxing.huchn@gmail.com>

* dnsmasq: backport dnssec security fixKevin Darbyshire-Bryant2018-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | CVE-2017-15107 An interesting problem has turned up in DNSSEC validation. It turns out that NSEC records expanded from wildcards are allowed, so a domain can include an NSEC record for *.example.org and an actual query reply could expand that to anything in example.org and still have it signed by the signature for the wildcard. So, for example !.example.org NSEC zz.example.org is fine. The problem is that most implementers (your author included, but also the Google public DNS people, powerdns and Unbound) then took that record to prove the nothing exists between !.example.org and zz.example.org, whereas in fact it only provides that proof between *.example.org and zz.example.org. This gives an attacker a way to prove that anything between !.example.org and *.example.org doesn't exists, when it may well do so.

* dnsmasq: use SIGINT for dnssec time validKevin Darbyshire-Bryant2018-01-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dnsmasq used SIGHUP to do too many things: 1) set dnssec time validation enabled, 2) bump SOA zone serial, 3) clear dns cache, 4) reload hosts files, 5) reload resolvers/servers files. Many subsystems within LEDE can send SIGHUP to dnsmasq: 1) ntpd hotplug (to indicate time is valid for dnssec) 2) odhcpd (to indicate a new/removed host - typically DHCPv6 leases) 3) procd on interface state changes 4) procd on system config state changes, 5) service reload. If dnssec time validation is enabled before the system clock has been set to a sensible time, name resolution will fail. Because name resolution fails, ntpd is unable to resolve time server names to addresses, so is unable to set time. Classic chicken/egg. Since commits 23bba9cb330cd298739a16e350b0029ed9429eef (service reload) & 4f02285d8b4a66359a8fa46f22a3efde391b5419 (system config) make it more likely a SIGHUP will be sent for events other than 'ntpd has set time' it is more likely that an errant 'name resolution is failing for everything' situation will be encountered. Fortunately the upstream dnsmasq people agree and have moved 'check dnssec timestamp enable' from SIGHUP handler to SIGINT. Backport the upstream patch to use SIGINT. ntpd hotplug script updated to use SIGINT. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

* dnsmasq: add listen_address parameterChristian Lamparter2017-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch adds a parser for the uci representation of dnsmasq's "-a | --listen-address" option. In summary, this option forces dnsmasq to listen on the given IP address(es). Both interface and listen-address options may be given, in which case the set of both interfaces and addresses is used. Note that if no interface option is given, but listen_address is, dnsmasq will not automatically listen on the loopback interface. To achieve this, the loopback IP addresses, 127.0.0.1 and/or ::1 must be explicitly added. This option is useful for ujailed dnsmasq instances, that would otherwise fail to work properly, because listening to the "This host on this network" address (aka 0.0.0.0 see rfc1700 page 4) may not be allowed.

| | | | | | | | | | | | | | Init script won't append --no-dhcp-interface option if interface protocol is one of: ncm, directip, qmi, mbim. This is caused by IP address assigned to dynamically created netifd interfaces. As a result there's no netmask assigned to the main interface and dhcp_add() function returns prematurely. By moving network subnet check we can ensure that --no-dhcp-interface is properly generated for wwan interfaces.
