* dnsmasq: Bump to v2.84Kevin Darbyshire-Bryant2021-02-081-3/+3
| | | | | | | | | | dnsmasq v2.84rc2 has been promoted to release. No functional difference between v2.83test3 and v2.84/v2.84rc2 Backport 2 patches to fix the version reporting Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
* dnsmasq: switch to ubus-based hotplug callDaniel Golle2021-02-081-2/+1
| | | | | | | | Use new ubus-based hotplug call in dhcp-script.sh As sysntpd now makes use of the new ubus-based hotplug calls, dnsmasq no longer needs to ship ACL to cover ntpd-hotplug. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* dnsmasq: Update to 2.84test3Kevin Darbyshire-Bryant2021-01-241-3/+3
| | | | | | | | | | | | | | | dnsmasq v2.83 has a bug in handling duplicate queries which means it may try to reply using the incorrect network socket. This is especially noticeable in dual stack environments where replies may be mis-directed to IPv4 addresses on an IPv6 socket or IPv6 addresses on an IPv4 socket. This results in system log spam such as: dnsmasq[16020]: failed to send packet: Network unreachable dnsmasq[16020]: failed to send packet: Address family not supported by protocol dnsmasq v2.84test3 resolves these issues.

* dnsmasq: Update to version 2.83Hauke Mehrtens2021-01-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following security problems in dnsmasq: * CVE-2020-25681: Dnsmasq versions before 2.83 is susceptible to a heap-based buffer overflow in sort_rrset() when DNSSEC is used. This can allow a remote attacker to write arbitrary data into target device's memory that can lead to memory corruption and other unexpected behaviors on the target device. * CVE-2020-25682: Dnsmasq versions before 2.83 is susceptible to buffer overflow in extract_name() function due to missing length check, when DNSSEC is enabled. This can allow a remote attacker to cause memory corruption on the target device. * CVE-2020-25683: Dnsmasq version before 2.83 is susceptible to a heap-based buffer overflow when DNSSEC is enabled. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap- allocated memory. This flaw is caused by the lack of length checks in rtc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in get_rdata() and cause a crash in Dnsmasq, resulting in a Denial of Service. * CVE-2020-25684: A lack of proper address/port check implemented in Dnsmasq version < 2.83 reply_query function makes forging replies easier to an off-path attacker. * CVE-2020-25685: A lack of query resource name (RRNAME) checks implemented in Dnsmasq's versions before 2.83 reply_query function allows remote attackers to spoof DNS traffic that can lead to DNS cache poisoning. * CVE-2020-25686: Multiple DNS query requests for the same resource name (RRNAME) by Dnsmasq versions before 2.83 allows for remote attackers to spoof DNS traffic, using a birthday attack (RFC 5452), that can lead to DNS cache poisoning. * CVE-2020-25687: Dnsmasq versions before 2.83 is vulnerable to a heap-based buffer overflow with large memcpy in sort_rrset() when DNSSEC is enabled. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rtc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in sort_rrset() and cause a crash in dnsmasq, resulting in a Denial of Service.

* dnsmasq: 'ipset' config sectionsAleksandr Mezin2020-11-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Allow configuring ipsets with dedicated config sections: config ipset list name 'ss_rules_dst_forward' list name 'ss_rules6_dst_forward' list domain 't.me' list domain 'telegram.org' instead of current, rather inconvenient syntax: config dnsmasq ... list ipset '/t.me/telegram.org/ss_rules_dst_forward,ss_rules6_dst_forward' Current syntax will still continue to work though.

* dnsmasq: support tftp_unique_root in /etc/config/dhcpW. Michael Petullo2020-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The TFTP server provided by dnsmasq supports serving a select boot image based on the client's MAC or IP address. This allows an administrator to activate this feature in /etc/config/dhcp. Here is an example /etc/config/dhcp that configures dnsmasq with --tftp-unique-root=mac: ... config dnsmasq option enable_tftp 1 option tftp_root /usr/libexec/tftpboot option tftp_unique_root mac config boot router option serveraddress 192.168.1.1 option servername tftp.example.com option filename openwrt-initramfs-kernel.bin ... With this configuration, dnsmasq will serve /usr/libexec/tftpboot/00-11-22-33-44-55/openwrt-initramfs-kernel.bin to the client with MAC address 00:11:22:33:44:55. Signed-off-by: W.

* dnsmasq: abort when dnssec requested but not availableYousong Zhou2020-08-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | Before this commit, if uci option "dnssec" was set, we pass "--dnssec" and friends to dnsmasq, let it start and decide whether to quit and whether to emit message for diagnosis # dnsmasq --dnssec; echo $? dnsmasq: DNSSEC not available: set HAVE_DNSSEC in src/config.h 1 DNSSEC as a feature is different from others like dhcp, tftp in that it's a security feature. Better be explicit. With this change committed, we make it so by not allowing it in the first in the initscript, should dnsmasq later decides to not quit (not likely) or quit without above explicit error (unlikely but less so ;) So this is just being proactive. on/off choices with uci option "dnssec" are still available like before Link: https://github.com/openwrt/openwrt/pull/3265#issuecomment-667795302 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>

* dnsmasq: fix dnssec+ntp chicken-and-egg workaround (FS#2574)Henrique de Moraes Holschuh2020-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Fix the test for an enabled sysntp initscript in dnsmasq.init, and get rid of "test -o" while at it. Issue reproduced on openwrt-19.07 with the help of pool.ntp.br and an RTC-less ath79 router. dnssec-no-timecheck would be clearly missing from /var/etc/dnsmasq.conf.* while the router was still a few days in the past due to non-working DNSSEC + DNS-based NTP server config. The fix was tested with the router in the "DNSSEC broken state": it properly started dnsmasq in dnssec-no-timecheck mode, and eventually ntp was able to resolve the server name to an IP address, and set the system time. DNSSEC was then enabled by SIGINT through the ntp hotplug hook, as expected. A missing system.ntp.enabled UCI node is required for the bug to show up. The reasons for why it would be missing in the first place were not investigated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is to make life easier for users with customized build of dnsmasq-full variant. Currently dnsmasq config generated by current service script will be rejected by dnsmasq build lacking DHCP feature - Options like --dhcp-leasefile have default values. Deleting them from uci config or setting them to empty value will make them take on default value in the end - Options like --dhcp-broadcast are output unconditionally Tackle this by - Check availablility of features from output of "dnsmasq --version" - Make a list of options guarded by HAVE_xx macros in src/options.c of dnsmasq source code - Ignore these options in xappend() Two things to note in this implementation - The option list is not exhaustive. Supposedly only those options that may cause dnsmasq to reject with "unsupported option (check that dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support)" are taken into account here - This provides a way out but users' cooperation is still needed. E.g. option dnssec needs to be turned off, otherwise the service script will try to add --conf-file pointing to dnssec specific anchor file which dnsmasq lacking dnssec support will reject Resolves FS#2281 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>

A new boolean option "localuse" is added to indicate that we intend to use dnsmasq as the local dns resolver. It's false by default and to align with old behaviour it will be true automatically if resolvfile is set to /tmp/resolv.conf.auto Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> Acked-by: Hans Dedecker <dedeckeh@gmail.com>
* dnsmasq: ensure test and rc order as older than final releasesJonas Gorski2019-02-171-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | Opkg treats text after a version number as higher than without: ~# opkg compare-versions "2.80rc1" "<<" "2.80"; echo $? 1 ~# opkg compare-versions "2.80rc1" ">>" "2.80"; echo $? 0 This causes opkg not offering final release as upgradable version, and even refusing to update, since it thinks the installed version is higher. This can be mitigated by adding ~ between the version and the text, as ~ will order as less than everything except itself. Since 'r' < 't', to make sure that test will be treated as lower than rc we add a second ~ before the test tag. That way, the ordering becomes 2.80~~test < 2.80~rc < 2.80 which then makes opkg properly treat prerelease versions as lower. Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>

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>

| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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. Drop the 'dnssec-improve-timestamp-heuristic' patch since it is neither used nor sent upstream. One less thing to refresh & maintain.

* dnsmasq: tighten config file permissionsKevin Darbyshire-Bryant2018-10-301-6/+6
| | | | | | | | | | | | | | | | | | Install following as config files (600) perms instead of as data (644) /usr/share/dnsmasq/dhcpbogushostname.conf /usr/share/dnsmasq/trust-anchors.conf /usr/share/dnsmasq/rfc6761.conf /etc/hotplug.d/ntp/25-dnsmasqsec /etc/config/dhcp /etc/dnsmasq.conf dnsmasq reads relevant config files before dropping root privilege and running as dnsmasq:dnsmasq ntpd runs as root so the hotplug script is still accessible Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
