+ --enable-selinux
+
+ Enable support for compiling SElinux type enforcement rules
+
+ The TE rules are needed if host environment is in enforcing
+ mode. Without this option, the VPN client process cannot
+ send notification to connman-vpnd via net.connman.Task
+ interface. The compiled connman-task.pp module needs to
+ also installed using this command
+ # semodule -i connman-task.pp
+ in order to enable the dbus access.
+
+ --with-dns-backend=TYPE
+
+ Enable support for a DNS resolving backend
+
+ Select a DNS backend to use. Supported values are "internal"
+ and "systemd-resolved". If "internal" is selected, ConnMan
+ will be build with a caching DNS proxy. If "systemd-resolved"
+ is selected, ConnMan configures systemd-resolved to do DNS
+ resolving. The default value is "internal".
+
+
+Activating debugging
+====================
+
+One can activate debugging prints in ConnMan using -d command line option.
+If the -d option has no parameters, then debugging is activated for all
+source code files. If the -d option has parameters, they tell which source
+code files have debugging activated. One can use wild cards in file names.
+Example:
+ -d Activate all normal debug prints
+ -d src/service.c This prints debugging info from src/service.c
+ file only
+ -d src/network.c:src/ipconfig.c
+ This activates debug prints in src/network.c
+ and src/ipconfig.c files.
+ -d 'src/n*.c' This would activate debug print from all the C source
+ files starting with letter 'n' in src directory.
+ Note the quotation marks around option, that is to
+ prevent shell expansion.
+ -d '*/n*.c:*/i*.c' Activate debug prints for all C source files starting
+ with letters 'n' or 'i' in any sub-directory.
+
+Some components of ConnMan have environment variable activated debug prints.
+If the environment variable is set, then corresponding component will print
+some extra debugging information.
+Following environment variables can be used:
+ CONNMAN_DHCP_DEBUG DHCPv4 related debug information
+ CONNMAN_DHCPV6_DEBUG DHCPv6 related debug information
+ CONNMAN_IPTABLES_DEBUG Extra information when iptables is used
+ CONNMAN_RESOLV_DEBUG Name resolver debug prints. These debug prints
+ are used when ConnMan resolves host names for
+ its own use.
+ Note that the DNS proxy debug prints do not
+ use this environment variable. For that, one
+ can use "-d src/dnsproxy.c" command line option.
+ CONNMAN_SUPPLICANT_DEBUG Debugging prints for communication between
+ connmand and wpa_supplicant processes.
+ CONNMAN_WEB_DEBUG Debug information when ConnMan does Internet
+ connectivity check in Wispr and 6to4 components.
+
+Example:
+ CONNMAN_WEB_DEBUG=1 src/connmand -n
+
+If timing conditions are relevant then it is recommended command to
+get log traces as follows:
+ connmand -d 2>&1 | ts '[%H:%M:%.S]' | tee connman.log
+
+The 'ts' program is normally available in the moreutils package.
+
+
+Kernel configuration
+====================
+
+In order to support tethering, the following kernel configuration options
+need to be enabled either as modules (m) or builtin (y):
+
+CONFIG_BRIDGE
+CONFIG_IP_NF_TARGET_MASQUERADE
+
+In order to enable CONFIG_IP_NF_TARGET_MASQUERADE, the following options need
+to be enabled also as modules (m) or builtin (y):
+
+CONFIG_NETFILTER
+CONFIG_NF_CONNTRACK_IPV4
+CONFIG_NF_NAT_IPV4
+
+For routing and statistic support in Sessions, the following options
+need to be enabled as modules (m) or builtin (y):
+
+CONFIG_IP_NF_IPTABLES
+CONFIG_IP_MULTIPLE_TABLES
+CONFIG_NETFILTER_NETLINK_ACCT
+CONFIG_NETFILTER_XT_MATCH_NFACCT
+CONFIG_NETFILTER_XT_CONNMARK
+CONFIG_NETFILTER_XT_TARGET_CONNMARK
+CONFIG_NETFILTER_XT_MATCH_CONNMARK
+
+In order to support USB gadget tethering, the following kernel configuration
+options need to be enabled:
+
+CONFIG_USB_GADGET
+CONFIG_USB_ETH
