The network interface can have DHCP +disabled, IPv4 only, IPv6 only, and IPv4/IPv6. + +Tested: +Using dbus-send or busctl: +Disabled DHCP, and confirmed only link local addresses were present. + +Assigned only static addresses. Both with/and without the gateway set +to 0.0.0.0 + +Deleted static IPv4 addresses. +Reassigned static addresses. + +Enabled DHCP for ipv4 only, and witnessed a DHCP server assign a valid +address. + +Assigned static IPv4 address. +Assigned static IPv6 address. +Confirmed both IPv4 and IPv6 static addresses are active. + +Enabled DHCP for ipv6 only, and confirmed the static v4 address +remains. The ipv6 address is removed, waiting for a DHCP6 server. + +Enabled DHCP for both ipv4 and ipv6. IPv4 address was assigned. IPv6 +address is assumed to succeed, as systemd config file enables IPv6 +DHCP. + +Change-Id: I2e0ff80ac3a5e88bcff28adac419bf21e37be162 +Signed-off-by: Johnathan Mantey <johnathanx.mantey@intel.com> +--- + Makefile.am | 1 + + configure.ac | 1 + + ethernet_interface.cpp | 147 ++++++++++++++++++++++--------- + ethernet_interface.hpp | 31 ++++++- + test/test_ethernet_interface.cpp | 3 +- + test/test_vlan_interface.cpp | 3 +- + types.hpp | 3 + + util.cpp | 16 +++- + util.hpp | 7 +- + vlan_interface.cpp | 2 +- + vlan_interface.hpp | 4 +- + 11 files changed, 165 insertions(+), 53 deletions(-) + +diff --git a/Makefile.am b/Makefile.am +index 1c47747..ff252fc 100644 +--- a/Makefile.am ++++ b/Makefile.am +@@ -97,6 +97,7 @@ phosphor_network_manager_CXXFLAGS = \ + $(SDEVENTPLUS_CFLAGS) \ + $(PHOSPHOR_DBUS_INTERFACES_CFLAGS) \ + $(PHOSPHOR_LOGGING_CFLAGS) \ ++ -DBOOST_ASIO_DISABLE_THREADS \ + -flto + if FEATURE_NIC_ETHTOOL + phosphor_network_manager_CXXFLAGS += -DNIC_SUPPORTS_ETHTOOL +diff --git a/configure.ac b/configure.ac +index 12d6caa..fed3e09 100644 +--- a/configure.ac ++++ b/configure.ac +@@ -36,6 +36,7 @@ AC_PATH_PROG([SDBUSPLUSPLUS], [sdbus++]) + PKG_CHECK_MODULES([PHOSPHOR_LOGGING], [phosphor-logging]) + PKG_CHECK_MODULES([PHOSPHOR_DBUS_INTERFACES], [phosphor-dbus-interfaces]) + PKG_CHECK_MODULES([LIBNL], [libnl-3.0 libnl-genl-3.0]) ++AC_CHECK_HEADER(boost/algorithm/string/split.hpp, [], [AC_MSG_ERROR([Could not find boost/algorithm/string/split.hpp])]) + + # Checks for header files. + AC_CHECK_HEADER(systemd/sd-bus.h, ,\ +diff --git a/ethernet_interface.cpp b/ethernet_interface.cpp +index 73fd8fe..ba6195e 100644 +--- a/ethernet_interface.cpp ++++ b/ethernet_interface.cpp +@@ -3,7 +3,6 @@ + #include "ethernet_interface.hpp" + + #include "config_parser.hpp" +-#include "ipaddress.hpp" + #include "neighbor.hpp" + #include "network_manager.hpp" + #include "vlan_interface.hpp" +@@ -40,9 +39,12 @@ using Argument = xyz::openbmc_project::Common::InvalidArgument;
