Revision 1.1.1.3 (vendor branch), Sun Apr 3 01:08:45 2022 UTC (23 months, 3 weeks ago) by christos
Import dhcp-4.4.3 Changes since 4.4.2-P1 (New Features) - Two new OMAPI function calls were added, `dhcpctl_timed_connect()` and `dhcpctl_timed_wait_for_completion()`. These provide timed versions of creating a connection and waiting for an operation to complete. [GitLab #76] - The BIND libraries have been updated to the latest version, 9.11.36. This fixes a number of compilation issues on various systems, including OpenWRT. Thanks to Philip Prindeville for testing on OpenWRT. [GitLab #218, #171, #180, #192] - Support was added for the new DHCPv4 option v6-only-preferred, specified in RFC 8925. A new reason code, V6ONLY, was added to the client script and the client Linux script sample was updated. [GitLab #132] Changes since 4.4.2-P1 (Bug Fixes) - Minor corrections were made to allow compilation under gcc 10. [GitLab #117] - The logic in dhclient that causes it to decline DHCPv4 leases if the client script exits abnormally (i.e. crashes) has been corrected. [GitLab #123] - The limit on the size of a lease file that can be loaded at startup is now only enforced on 32-bit systems. [GitLab #92] - The PRNG initialization has been improved. It now uses the configure flag `--with-randomdev=PATH`, which specifies the device from which to read the initial seed. That is typically `/dev/random` (the default value) or `/dev/urandom`, but may be specified otherwise on the local system. The old behavior can be forced by disabling this feature (`--with-randomdev=no`). If the initialization is disabled or reading from the random device fails, the previous algorithm (retrieve the last four bytes of hardware addresses from all network interfaces that have them, and use the current time and process ID) is used. [GitLab #197] - A minor dhclient code fix was made to remove compilation warnings. [GitLab #190] - The hard-coded MD5 algorithm name was removed in OMAPI connection logic. Previously, using any other algorithm via a key-algorithm statement would allow OMAPI connections to be made, but subsequent actions such as updating an object would fail. [GitLab #148] - The parallel build has been improved. Thanks to Sergei Trofimovich for the patch. The parallel build is still experimental, as officially the BIND 9 code does not support the parallel build for libraries. [GitLab #91] - Handling of LDAP options (`ldap-gssapi-principal` and `ldap-gssapi-keytab`) has been improved. This is contributed code that has not been tested by ISC. Thank you to Petr Mensik and Pavel Zhukov for the patches! [GitLab !56,!75] - It is now possible to use `option -g ipaddr` in the dhcrelay to replace the giaddr sent to clients with the given ipaddr, to work around bogus clients like Solaris 11 grub which use giaddr instead of the announced router (3) to set up their default route. Thanks to Jens Elkner for the patch! [GitLab #223, !86, !92] |
