* dnsmasq: hotplug script tidyupKevin Darbyshire-Bryant2020-05-102-6/+3
| | | | | | | | Hotplug scripts are sourced so the #!/bin/sh is superfluous/deceptive. Re-arrange script to only source 'procd' if we get to the stage of needing to signal the process, reduce hotplug processing load a little. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
* dnsmasq: always inform about disabled dhcp servicePetr Štetiar2020-04-301-6/+6
| | | | | | | | | | | | | | | | | Init script checks for an already active DHCP server on the interface and if such DHCP server is found, then it logs "refusing to start DHCP" message, starts dnsmasq without DHCP service unless `option force 1` is set and caches the DHCP server check result. Each consecutive service start then uses this cached DHCP server check result, but doesn't provide log feedback about disabled DHCP service anymore. So this patch ensures, that the log message about disabled DHCP service on particular interface is always provided.

* dnsmasq: fix dnssec+ntp chicken-and-egg workaround (FS#2574)Henrique de Moraes Holschuh2020-03-252-4/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | Add option 'scriptarp' to uci dnsmasq config to enable --script-arp functions. The default setting is false, meaning any scripts in `/etc/hotplug.d/neigh` intended to be triggered by `/usr/lib/dnsmasq/dhcp-script.sh` will fail to execute.

* dnsmasq: skip options that are not compiled inYousong Zhou2019-06-092-3/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* dnsmasq: allow using dnsmasq as the sole resolverYousong Zhou2019-02-192-16/+16
| | | | | | | | | | | | | | | | | | | | Currently it seems impossible to configure /etc/config/dhcp to achieve the following use case - run dnsmasq with no-resolv - re-generate /etc/resolv.conf with "nameserver 127.0.0.1" Before this change, we have to set resolvfile to /tmp/resolv.conf.auto to achive the 2nd effect above, but setting resolvfile requires noresolv being false. 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>

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

| | | | | | | | | | | Backport upstream commit Change anti cache-snooping behaviour with queries with the recursion-desired bit unset. Instead to returning SERVFAIL, we now always forward, and never answer from the cache. This allows "dig +trace" command to work. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
