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;
