* Sun Jan 24 2021 Dirk Müller - update to 4.4.2:
* Please note that that ISC DHCP is now licensed under the Mozilla Public License, MPL 2.0. In general, the areas of focus for ISC DHCP 4.4 were: 1. Dynamic DNS additions 2. dhclient improvements 3. Support for dynamic shared libraries
* Added the interface name to socket initialization failure log messages. Prior to this the log messages stated only the error reason without stating the target interface.
* Corrected buffer pointer logic in dhcrelay functions that manipulate agent relay options. Thanks to Thomas Imbert of MSRC Vulnerabilities & Mitigations for reporting the issue.
* Corrected unresolved symbol errors building relay_unittests when configured to build using libtool.
* A new configuration parameter, ping-cltt-secs (v4 operation only), has been added to allow the user to specify the number of seconds that must elapse since CLTT before a ping check is conducted. Prior to this, the value was hard coded at 60 seconds. Please see the server man pages for a more detailed discussion.
* A new configuration parameter, ping-timeout-ms (v4 operation only), has been added that allows the user to specify the amount of time the server waits for a ping-check response in milliseconds rather than in seconds (via ping-timeout). When greater than zero, the value of ping-timeout-ms will override the value of ping-timeout. Thanks to Jay Doran from Bluecat Networks for suggesting this feature.
* An experimental tool called, Keama (KEA Migration Assistant), which helps translate ISC DHCP configurations to Kea configurations, is now included in the distribution.
* Corrected a misuse of the BIND9 DDNS API which caused DDNS updates to be carried out over TCP rather than UDP. The coding error was exposed by migration to BIND9 9.11. Thanks to Jinmei Tatuya at Infoblox for reporting the issue.
* Bind9 now defaults to requiring python to build. The Makefile for building Bind9 when bundled with ISC DHCP was modified to turn off this dependency.
* Corrected a dual-stack mixed-mode issue that occurs when both ddns-guard-id-must-match and ddns-other-guard-is-dynamic are enabled and that caused the server to incorrectly interpret the presence of a guard record belonging to another client as a case of no guard record at all. Thanks to Fernando Soto from BlueCat Networks for reporting this issue.
* Corrected a compilation issue that occurred when building without DNS update ability (e.g. by undefining NSUPDATE).
* Corrected an issue that was causing the server, when running in DHPCv4 mode, to segfault when class lease limits are reached. Thanks to Peter Nagy at Porion-Digital for reporting the matter and submitting a patch.
* Made minor changes to eliminate warnings when compiled with GCC 9. Thanks to Brett Neumeier for bringing the matter to our attention.
* Fixed potential memory leaks in parser error message generation spotted by Coverity, CIDs: 1448191, 1448193, 1448194, 1448195
* Updated URL of IEEE oui.txt in contrib/dhcp-lease-list.pl. Thanks to Tommy Smith for contributing the patch.
* Fixed define flags when using SO_BINDTODEVICE. Thanks to Joe LeVeque for reporting the issue.
* Applied a patch from OpenBSD to always set the scope id of outbound DHPCv6 packets. Note this change only applies when compiling under OpenBSD. Thanks to Brad Smith at OpenBSD from bringing it to our attention.
* Modified dhclient to not discard config file leases that are duplicates of server-provided leases and to retain such leases after they have been used as the fallback active lease and DHCP service has been restored. This allows them to be used more than once during the lifetime of a dhclient instance. This applies to DHCPv4 operation only.
* Corrected a number of reference counter and zero-length buffer leaks. Thanks to Christopher Ertl of MSRC Vulnerabilities & Mitigations for pointing them out.
* Closed a small window of time between the installation of graceful shutdown signal handlers and application context startup, during which the receipt of shutdown signal would cause a REQUIRE() assertion to occur. Note this issue is only visible when compiling with ENABLE_GENTLE_SHUTDOWN defined.
* Corrected a buffer overflow that can occur when retrieving zone names that are more than 255 characters in length.
* The \"d\" domain name option format was incorrectly handled as text instead of RFC 1035 wire format. Thanks to Jay Doran at BlueCat Networks for reporting this issue.
* Improved the error message issued when a host declaration has both a uid and a dhcp-client-identifier. Server configuration parsing will now fail if a host declaration specifies more than one uid.
* Updated developer\'s documentation on building and running unit tests. Removed support for --with-atf=bind as BIND9 no longer bundles in ATF source.
* Fixed a syntax error in ldap.c which cropped up under Ubuntu 18.04.1/gcc 7.4.0. Thanks to Charles Hedrick for pointing it out.
* Added clarification to dhcp-options.5 section on ip-address values describing the first-use DNS resolution of options with hostnames as values (e.g. next-server).
* The option format for the server option omapi-key was changed to a format type \'k\' (key name); while server options ldap-port and ldap-init-retry were changed to \'L\' (unsigned 32-bit integer). These three options were inadvertantly broken when the \'d\' format content was changed to comply with RFC 1035 wire format (see Gitlab #2).
* A delayed-ack value of 0 (the default), now correctly disables the delayed feature. A change in 4.4.0 prohibited lease updates marking leases active from be written to the lease file when delayed-ack is 0. This in turn, caused servers to lose active lease assignments upon restart. ! Option reference count was not correctly decremented in error path when parsing buffer for options. Reported by Felix Wilhelm, Google Security Team. CVE: CVE-2018-5733 ! Corrected an issue where large sized \'X/x\' format options were causing option handling logic to overwrite memory when expanding them to human readable form. Reported by Felix Wilhelm, Google Security Team. CVE: CVE-2018-5732
* Added use of new Bind9 compatibility header files, that are now necessary to supply type definitions for primitive data types, removed from Bind9 proper. Altered util/bind.sh to pull from Bind9 repo on gitlab.
* Duplicate address detection when binding to a new IPv6 address was added to the following dhclient scripts: linux,freebsd,netbsd,openbsd, and macos. The scripts will check for DAD errors after binding to a new IPv6 address for at most --dad-wait-time seconds. If a DAD error is detected the script will exit with a value of 3, instructing dhclient to decline the address. If dad-wait-time is zero (the default), DAD error checking is not peformed.
* Support for sending and receiving additional DHCP4 options has been added to both the dhcpd and dhclient. Specifically: option codes 93,94, and 97 (RFC 4578); code 150 (RFC 5859); and codes 209,219, and 211 (RFC 5071). Beyond configuring, sending, requesting, and receiving these options neither server nor client apply any additional logic based on their values. Thanks to Peter Lewis for requesting this change.
* Added clarifying text to dhcpd.conf.5 explaining the class match expressions cannot rely on the results of executable statements.
* Fixed a bug which causes dhcpd and dhclient to crash on certain systems when given relative path names for lease or pid files on the command line. Affected systems are those on which the C library function, realpath() does not support a second parameter value of NULL (see manpages for realpath(3)).
* Fixed a build issue when building with embedded BIND9 under OpenBSD that was causing BIND9 build to not generate dns/enumclass.h and dns/enumtype.h.
* Added /m4/README to the distribution tarball. Some versions of ac_local() treat the absence of the m4 subdirectory as error rather than warning. This was causing the call to autoreconf, necessary for building with libtool, to fail.
* Added experimental support for relay port (draft-ietf-dhc-relay-port-10.txt) feature for DHCPv4, DHCPv6 and DHCPv4-over-DHCPv6. Relay port has to be enabled at compile time via --enable-relay-port and is fully backward compatible (i.e. works with previous implementations of servers and relays using the standard ports). A new --rp command line option specifies to dhcrelay an alternate source port for upstream (i.e. toward the server) messages. Thanks to Naiming Shen and Enke Chen of Cisco systems for submitting these patches.
* Added --release-on-roam to dhcpd server. When enabled and the server detects that a DHCPv6 client (IAID+DUID) has roamed to a new network, it will release the pre-existing leases on the old network and emit a log statement similar to the following: \"Client: roamed to new network, releasing lease:

\" The server will carry out all of the same steps that would normally occur when a client explicitly releases a lease. This behavior is disabled by default and may only be specified globally. Prior to this the server renders the leases unavailable until they expire or the server is restarted. Clients that need leases in multiple networks must supply a unique IAID in each IA. When release-on-roam is disabled (the default) the server maintains the prior behavior of making such leases unavailable until they expire or the server is restarted. Clients that need leases in multiple networks must supply a unique IAID in each IA. This parameter may only be specified at the global level. Thanks to Fernando Soto from BlueCat Networks for suggesting this change.
* Support for delayed-ack is now compiled in by default. Prior to this it had to be enabled at compile time via --enable-delayed-acks. The default value for delayed-ack, however, has been changed from 28 to 0 (i.e. disabled). This was done to minimize the impact on users not currently using the feature. Please note that the delayed-ack feature is not currently compatible with support for DHPCv4-over-DHCPv6 so when a 4to6 port command line argument enables this in the server the delayed-ack value is reset to 0.
* Added to the server (-6) a new statement, local-address6, which specifies the source address of packets sent by the server. An additional flag, bind-local-address6, disabled by default, binds the service socket to to local-address6. Note that bind-local-address does not work with direct clients: a relay has to forward packets to the server using the local-address6 destination.
* The server now recognizes environment variables PATH_DHCPD_DB and PATH_DHCPD_PID. These had been incorrectly compiled out of the code unless DHCPv6 support was disabled. Additionally, the server man pages were corrected to accurately reflect how the server chooses file names (see lease-file-name and pid-file-name statements). Thanks to Fernando Soto at Bluecat Networks for bringing this matter to our attention.
* Removed an \"Impossible condition\" error upon exit in the dhcpd server that has been shutdown via OMAPI. This condition was only apparent under Solaris when building with --enable-use-sockets and --enable-ipv4-pktinfo.
* Corrected some minor Coverity issues: CID 1426059, 1426058, and 1426057.
* Added missing text to dhclient.8 and expanded release note coverage for --address-prefix-len changes.- remove dhcp-CVE-2019-6470.patch, 0013-dhcp-4.2.x-dhcpv6-decline-on-DAD-failure.872609.patch: merged upstream- 0006-dhcp-4.3.2-dhclient-send-hostname-or-fqdn.patch 0009-dhcp-4.2.6-close-on-exec.patch 0016-infiniband-support.patch 0018-client-fail-on-script-pre-init-error-bsc-912098.patch 0021-dhcp-ip-family-symlinks.patch: refresh against newer code base- build with --enable-log-pid (log pid) and enable-binary-leases (faster binary looup for large leases files)
