From: Eric Le Bihan Date: Sat, 17 Sep 2016 11:58:37 +0000 (+0200) Subject: system(d): allow auto net configuration with networkd X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=84d997d6890f1d045c4d6084148fd9b2d674a6c7;p=buildroot.git system(d): allow auto net configuration with networkd Allow automatic network configuration via systemd-networkd if selected. If systemd-networkd is enabled and $BR2_SYSTEM_DHCP is set, then create a .network file to configure the selected network interface via DHCP. Signed-off-by: Eric Le Bihan [Thomas: - merge the two patches from Eric into just one - instead of generating the dhcp.network file completely from the .mk file, use a template file, and "sed" it with the right network interface] Signed-off-by: Thomas Petazzoni --- diff --git a/package/systemd/systemd.mk b/package/systemd/systemd.mk index 278c8e93cc..fce5d8411c 100644 --- a/package/systemd/systemd.mk +++ b/package/systemd/systemd.mk @@ -281,6 +281,14 @@ define SYSTEMD_INSTALL_RESOLVCONF_HOOK ln -sf ../run/systemd/resolve/resolv.conf \ $(TARGET_DIR)/etc/resolv.conf endef +SYSTEMD_NETWORKD_DHCP_IFACE = $(call qstrip,$(BR2_SYSTEM_DHCP)) +ifneq ($(SYSTEMD_NETWORKD_DHCP_IFACE),) +define SYSTEMD_INSTALL_NETWORK_CONFS + sed s/SYSTEMD_NETWORKD_DHCP_IFACE/$(SYSTEMD_NETWORKD_DHCP_IFACE)/ \ + package/systemd/dhcp.network > \ + $(TARGET_DIR)/etc/systemd/network/dhcp.network +endef +endif else SYSTEMD_CONF_OPTS += --disable-networkd define SYSTEMD_INSTALL_SERVICE_NETWORK @@ -383,6 +391,7 @@ define SYSTEMD_INSTALL_INIT_SYSTEMD $(SYSTEMD_INSTALL_SERVICE_TTY) $(SYSTEMD_INSTALL_SERVICE_NETWORK) $(SYSTEMD_INSTALL_SERVICE_TIMESYNC) + $(SYSTEMD_INSTALL_NETWORK_CONFS) endef $(eval $(autotools-package)) diff --git a/system/Config.in b/system/Config.in index 875ed376bf..3ddf8433d4 100644 --- a/system/Config.in +++ b/system/Config.in @@ -372,7 +372,7 @@ config BR2_TARGET_GENERIC_REMOUNT_ROOTFS_RW config BR2_SYSTEM_DHCP string "Network interface to configure through DHCP" default "" - depends on !BR2_PACKAGE_SYSTEMD_NETWORKD && (BR2_PACKAGE_BUSYBOX || BR2_PACKAGE_IFUPDOWN) + depends on BR2_PACKAGE_BUSYBOX || BR2_PACKAGE_IFUPDOWN || BR2_PACKAGE_SYSTEMD_NETWORKD help Enter here the name of the network interface (E.G. eth0) to automatically configure through DHCP at bootup. @@ -382,11 +382,8 @@ config BR2_SYSTEM_DHCP For more complicated network setups use an overlay to overwrite /etc/network/interfaces or add a networkd configuration file. -comment "automatic network configuration via DHCP is not compatible with networkd" - depends on BR2_PACKAGE_SYSTEMD_NETWORKD - -comment "automatic network configuration via DHCP needs ifupdown or busybox" - depends on !(BR2_PACKAGE_BUSYBOX || BR2_PACKAGE_IFUPDOWN) +comment "automatic network configuration via DHCP needs ifupdown or busybox or networkd" + depends on !(BR2_PACKAGE_BUSYBOX || BR2_PACKAGE_IFUPDOWN || BR2_PACKAGE_SYSTEMD_NETWORKD) endif # BR2_ROOTFS_SKELETON_DEFAULT
