CHANGELOG.md

AdGuard Home Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

• The ability to put ClientIDs into DNS-over-HTTPS hostnames as opposed to URL paths (#3418). Note that AdGuard Home checks the server name only if the URL does not contain a ClientID.

v0.107.16 - 2022-10-07

This is a security update. There is no GitHub milestone, since no GitHub issues were resolved.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-2879, CVE-2022-2880, and CVE-2022-41715 Go vulnerabilities fixed in Go 1.18.7.

v0.107.15 - 2022-10-03

See also the v0.107.15 GitHub milestone.

Security

• As an additional CSRF protection measure, AdGuard Home now ensures that requests that change its state but have no body (such as POST /control/stats_reset requests) do not have a Content-Type header set on them (#4970).

Added

Experimental HTTP/3 Support

See #3955 and the related issues for more details. These features are still experimental and may break or change in the future.

• DNS-over-HTTP/3 DNS and web UI client request support. This feature must be explicitly enabled by setting the new property dns.serve_http3 in the configuration file to true.
• DNS-over-HTTP upstreams can now upgrade to HTTP/3 if the new configuration file property dns.use_http3_upstreams is set to true.
• Upstreams with forced DNS-over-HTTP/3 and no fallback to prior HTTP versions using the h3:// scheme.

Fixed

• User-specific blocked services not applying correctly (#4945, #4982, #4983).
• only application/json is allowed errors in various APIs (#4970).

v0.107.14 - 2022-09-29

See also the v0.107.14 GitHub milestone.

Security

A Cross-Site Request Forgery (CSRF) vulnerability has been discovered. The CVE number is to be assigned. We thank Daniel Elkabes from Mend.io for reporting this vulnerability to us.

SameSite Policy

The SameSite policy on the AdGuard Home session cookies is now set to Lax. Which means that the only cross-site HTTP request for which the browser is allowed to send the session cookie is navigating to the AdGuard Home domain.

Users are strongly advised to log out, clear browser cache, and log in again after updating.

Removal Of Plain-Text APIs (BREAKING API CHANGE)

We have implemented several measures to prevent such vulnerabilities in the future, but some of these measures break backwards compatibility for the sake of better protection.

The following APIs, which previously accepted or returned text/plain data, now accept or return data as JSON. All new formats for the request and response bodies are documented in openapi/openapi.yaml and openapi/CHANGELOG.md.

• GET /control/i18n/current_language;
• POST /control/dhcp/find_active_dhcp;
• POST /control/filtering/set_rules;
• POST /control/i18n/change_language.

Stricter Content-Type Checks (BREAKING API CHANGE)

All JSON APIs that expect a body now check if the request actually has Content-Type set to application/json.

Other Security Changes

• Weaker cipher suites that use the CBC (cipher block chaining) mode of operation have been disabled (#2993).

Added

• Support for plain (unencrypted) HTTP/2 (#4930). This is useful for AdGuard Home installations behind a reverse proxy.

Fixed

• Incorrect path template in DDR responses (#4927).

v0.107.13 - 2022-09-14

See also the v0.107.13 GitHub milestone.

Added

• The new optional dns.ipset_file property, which can be set in the configuration file. It allows loading the ipset list from a file, just like dns.upstream_dns_file does for upstream servers (#4686).

Changed

• The minimum DHCP message size is reassigned back to BOOTP's constraint of 300 bytes (#4904).

Fixed

• Panic when adding a static lease within the disabled DHCP server (#4722).

v0.107.12 - 2022-09-07

See also the v0.107.12 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-27664 and CVE-2022-32190 Go vulnerabilities fixed in Go 1.18.6.

Added

• New bool, dur, u8, and u16 DHCP options to provide more convenience on options control by setting values in a human-readable format (#4705). See also a Wiki page.

• New del DHCP option which removes the corresponding option from server's response (#4337). See also a Wiki page.

  NOTE: This modifier affects all the parameters in the response and not only the requested ones.

• A new HTTP API, GET /control/blocked_services/services, that lists all available blocked services (#4535).

Changed

• The DHCP options handling is now closer to the RFC 2131 (#4705).
• When the DHCP server is enabled, queries for domain names under dhcp.local_domain_name not pointing to real DHCP client hostnames are now processed by filters (#4865).
• The DHCPREQUEST handling is now closer to the RFC 2131 (#4863).
• The internal DNS client, used to resolve hostnames of external clients and also during automatic updates, now respects the upstream mode settings for the main DNS client (#4403).

Deprecated

• Ports 784 and 8853 for DNS-over-QUIC in Docker images. Users who still serve DoQ on these ports are encouraged to move to the standard port 853. These ports will be removed from the EXPOSE section of our Dockerfile in a future release.
• Go 1.18 support. Future versions will require at least Go 1.19 to build.

Fixed

• The length of the DHCP server's response is now at least 576 bytes as per RFC 2131 recommendation (#4337).
• Dynamic leases created with empty hostnames (#4745).
• Unnecessary logging of non-critical statistics errors (#4850).

• invalid argument errors during update checks on older Linux kernels (#4670).
• Data races and concurrent map access in statistics module (#4358, #4342).

v0.107.9 - 2022-08-03

See also the v0.107.9 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-32189 Go vulnerability fixed in Go 1.18.5. Go 1.17 support has also been removed, as it has reached end of life and will not receive security updates.

Added

• Domain-specific upstream servers test. If such test fails, a warning message is shown (#4517).
• windows/arm64 support (#3057).

Changed

• UI and update links have been changed to make them more resistant to DNS blocking.

Fixed

• DHCP not working on most OSes (#4836).
• Several UI issues (#4775, #4776, #4782).

v0.107.8 - 2022-07-13

See also the v0.107.8 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-1705, CVE-2022-32148, CVE-2022-30631, and other Go vulnerabilities fixed in Go 1.17.12.

v0.107.7 - 2022-06-06

See also the v0.107.7 GitHub milestone.

Security

• Go version has been updated to prevent the possibility of exploiting the CVE-2022-29526, CVE-2022-30634, CVE-2022-30629, CVE-2022-30580, and CVE-2022-29804 Go vulnerabilities.
• Enforced password strength policy (#3503).

Added

• Support for the final DNS-over-QUIC standard, RFC 9250 (#4592).
• Support upstreams for subdomains of a domain only (#4503).
• The ability to control each source of runtime clients separately via clients.runtime_sources configuration object (#3020).
• The ability to customize the set of networks that are considered private through the new dns.private_networks property in the configuration file (#3142).
• EDNS Client-Subnet information in the request details section of a query log record (#3978).
• Support for hostnames for plain UDP upstream servers using the udp:// scheme (#4166).
• Logs are now collected by default on FreeBSD and OpenBSD when AdGuard Home is installed as a service (#4213).

Changed

• On OpenBSD, the daemon script now uses the recommended /bin/ksh shell instead of the /bin/sh one (#4533). To apply this change, backup your data and run AdGuardHome -s uninstall && AdGuardHome -s install.

• The default DNS-over-QUIC port number is now 853 instead of 754 in accordance with RFC 9250 (#4276).

• Reverse DNS now has a greater priority as the source of runtime clients' information than ARP neighborhood.

• Improved detection of runtime clients through more resilient ARP processing (#3597).

• The TTL of responses served from the optimistic cache is now lowered to 10 seconds.

• Domain-specific private reverse DNS upstream servers are now validated to allow only *.in-addr.arpa and *.ip6.arpa domains pointing to locally-served networks (#3381).

  NOTE: If you already have invalid entries in your configuration, consider removing them manually, since they essentially had no effect.

• Response filtering is now performed using the record types of the answer section of messages as opposed to the type of the question (#4238).

• Instead of adding the build time information, the build scripts now use the standardized environment variable SOURCE_DATE_EPOCH to add the date of the commit from which the binary was built (#4221). This should simplify reproducible builds for package maintainers and those who compile their own AdGuard Home.

• The property local_domain_name is now in the dhcp object in the configuration file to avoid confusion (#3367).

• The dns.bogus_nxdomain property in the configuration file now supports CIDR notation alongside IP addresses (#1730).

Configuration Changes

In this release, the schema version has changed from 12 to 14.

• Object clients, which in schema versions 13 and earlier was an array of actual persistent clients, is now consist of persistent and runtime_sources properties:

  # BEFORE:
  'clients':
  - name: client-name
    # …
  
  # AFTER:
  'clients':
    'persistent':
      - name: client-name
        # …
    'runtime_sources':
      whois: true
      arp: true
      rdns: true
      dhcp: true
      hosts: true

  The value for clients.runtime_sources.rdns field is taken from dns.resolve_clients property. To rollback this change, remove the runtime_sources property, move the contents of persistent into the clients itself, the value of clients.runtime_sources.rdns into the dns.resolve_clients, and change the schema_version back to 13.

• Property local_domain_name, which in schema versions 12 and earlier used to be a part of the dns object, is now a part of the dhcp object:

  # BEFORE:
  'dns':
    # …
    'local_domain_name': 'lan'
  
  # AFTER:
  'dhcp':
    # …
    'local_domain_name': 'lan'

  To rollback this change, move the property back into the dns object and change the schema_version back to 12.

Deprecated

• The --no-etc-hosts option. Its functionality is now controlled by clients.runtime_sources.hosts configuration property. v0.109.0 will remove the flag completely.

Fixed

• Query log occasionally going into an infinite loop (#4591).
• Service startup on boot on systems using SysV-init (#4480).
• Detection of the stopped service status on macOS and Linux (#4273).
• Case-sensitive ClientID (#4542).
• Slow version update queries making other HTTP APIs unresponsive (#4499).
• ARP tables refreshing process causing excessive PTR requests (#3157).

v0.107.6 - 2022-04-13

See also the v0.107.6 GitHub milestone.

Security

• User-Agent HTTP header removed from outgoing DNS-over-HTTPS requests.

Added

• Support for SVCB/HTTPS parameter dohpath in filtering rules with the dnsrewrite modifier according to the RFC draft (#4463).

Changed

• Filtering rules with the dnsrewrite modifier that create SVCB or HTTPS responses should use ech instead of echconfig to conform with the latest drafts.

Deprecated

• SVCB/HTTPS parameter name echconfig in filtering rules with the dnsrewrite modifier. Use ech instead. v0.109.0 will remove support for the outdated name echconfig.
• Obsolete --no-mem-optimization option (#4437). v0.109.0 will remove the flag completely.

Fixed

• I/O timeout errors when checking for the presence of another DHCP server.
• Network interfaces being incorrectly labeled as down during installation.

• The Vary header is now added along with Access-Control-Allow-Origin to prevent cache-related and other issues in browsers (#2658).
• The request body size limit is now set for HTTPS requests as well.
• Incorrect version tag in the Docker release (#2663).

v0.105.0 - 2021-02-10

See also the v0.105.0 GitHub milestone.

Added

• Added more services to the "Blocked services" list (#2224, #2401).
• ipset subdomain matching, just like dnsmasq does (#2179).
• ClientID support for DNS-over-HTTPS, DNS-over-QUIC, and DNS-over-TLS (#1383).
• The new dnsrewrite modifier for filters (#2102).
• The host checking API and the query logs API can now return multiple matched rules (#2102).
• Detecting of network interface configured to have static IP address via /etc/network/interfaces (#2302).
• DNSCrypt protocol support (#1361).
• A 5 second wait period until a DHCP server's network interface gets an IP address (#2304).
• dnstype modifier for filters (#2337).
• HTTP API request body size limit (#2305).

Changed

• Access-Control-Allow-Origin is now only set to the same origin as the domain, but with an HTTP scheme as opposed to * (#2484).
• workDir now supports symlinks.
• Stopped mounting together the directories /opt/adguardhome/conf and /opt/adguardhome/work in our Docker images (#2589).
• When dns.bogus_nxdomain option is used, the server will now transform responses if there is at least one bogus address instead of all of them (#2394). The new behavior is the same as in dnsmasq.
• Post-updating relaunch possibility is now determined OS-dependently (#2231, #2391).
• Made the mobileconfig HTTP API more robust and predictable, add parameters and improve error response (#2358).
• Improved HTTP requests handling and timeouts (#2343).
• Our snap package now uses the core20 image as its base (#2306).
• New build system and various internal improvements (#2271, #2276, #2297, #2509, #2552, #2639, #2646).

Deprecated

• Go 1.14 support. v0.106.0 will require at least Go 1.15 to build.
• The darwin/386 port. It will be removed in v0.106.0.
• The "rule" and "filter_id" fields in GET /filtering/check_host and GET /querylog responses. They will be removed in v0.106.0 (#2102).

Fixed

• Autoupdate bug in the Darwin (macOS) version (#2630).
• Unnecessary conversions from string to net.IP, and vice versa (#2508).
• Inability to set DNS cache TTL limits (#2459).
• Possible freezes on slower machines (#2225).
• A mitigation against records being shown in the wrong order on the query log page (#2293).
• A JSON parsing error in query log (#2345).
• Incorrect detection of the IPv6 address of an interface as well as another infinite loop in the /dhcp/find_active_dhcp HTTP API (#2355).

Removed

• The undocumented ability to use hostnames as any of bind_host values in configuration. Documentation requires them to be valid IP addresses, and now the implementation makes sure that that is the case (#2508).
• Dockerfile (#2276). Replaced with the script scripts/make/build-docker.sh which uses scripts/make/Dockerfile.
• Support for pre-v0.99.3 format of query logs (#2102).
