2016-05-17networkd: add route expiration handler (#3242)Susant Sahani
Fix for #3232.
2016-05-17networkd: Add EmitRouter= option for DHCP Server (#3251)Clemens Gruber
Add an option to disable appending DHCP option 3 (Router) to the DHCP OFFER and ACK packets. This commit adds the boolean option EmitRouter= for the [DHCPServer] section in .network files. Rationale: On embedded devices, it is very useful to have a DHCP server running on an USB OTG ethernet gadget interface to avoid manual setup on the client PCs, but it should only serve IP addresses, no route(r)s. Otherwise, Windows clients experience network connectivity issues, due to them using the address set in DHCP option 3 as default gateway. Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>

2016-05-15networkd: do not generate a mac address for vlan interfaces (#3221)Susant Sahani
While creating a VLAN the mac address should be copied from the parent interface, so that the VLANs inherit the MAC address of the physical interface. Before: ``` 3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:26:c6:85:a3:c2 brd ff:ff:ff:ff:ff:ff ... 6: vlan1@wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 22:07:73:9d:43:59 brd ff:ff:ff:ff:ff:ff 7: vlan2@wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 46:30:76:33:35:d4 brd ff:ff:ff:ff:ff:ff ``` After: ``` 3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:26:c6:85:a3:c2 brd ff:ff:ff:ff:ff:ff ... 11: vlan1@wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 00:26:c6:85:a3:c2 brd ff:ff:ff:ff:ff:ff 12: vlan2@wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 00:26:c6:85:a3:c2 brd ff:ff:ff:ff:ff:ff ``` v2 of #1573, with fixed commit message.
2016-05-15networkd: bridge add support to configure multicast snooping (#3223)Susant Sahani
This patch implements support for the IFLA_BR_MCAST_SNOOPING attribute it can change the multicast snooping value. IGMP snooping monitors the Internet Group Management Protocol (IGMP) traffic between hosts and multicast routers.

2016-05-14networkd: drop route_dropZbigniew Jędrzejewski-Szmek
It is just an alias for route_free which requires that route is not null, but it was only used in one place where it was checked that route is not null anyway. Let's just call route_free instead.

2016-05-09tree-wide: rename draw_special_char to special_glyphZbigniew Jędrzejewski-Szmek
That function doesn't draw anything on it's own, just returns a string, which sometimes is more than one character. Also remove "DRAW_" prefix from character names, TREE_* and ARROW and BLACK_CIRCLE are unambigous on their own, don't draw anything, and are always used as an argument to special_glyph(). Rename "DASH" to "MDASH", as there's more than one type of dash.
2016-05-09networkd: reworkd LLDP emission to allow control of propagation levelLennart Poettering
This allows selecting the propagation level of emitted LLDP packets (specifically: the destination MAC address of the packets). This is useful because it allows generating LLDP packets that optionally cross certain types of bridges. See 802.11ab-2009, Table 7-1 for details.

Closes #2166. We only allow 0, infinity and forever. infinity and forever is same.
2016-05-03networkd: add support to set route tableSusant Sahani
networkd: add support to set route table 1. add support to configure the table id. if id is less than 256 we can fit this in the header of route as netlink property is a char. But in kernel this proepty is a unsigned 32. Hence if greater that 256 add this as RTA_TABLE attribute. 2. we are not setting the address family now. Now set this property.

2016-05-03networkd: rework duid_{type,duid_type,duid,duid_len} settingZbigniew Jędrzejewski-Szmek
Separate fields are replaced with a struct. Second second duid type field is removed. The first field was used to carry the result of DUIDType= configuration, and the second was either a copy of this, or contained the type extracted from DuidRawData. The semantics are changed so that the type specified in DUIDType is always used. DUIDRawData= no longer overrides the type setting. The networkd code is now more constrained than the sd-dhcp code: DUIDRawData cannot have 0 length, length 0 is treated the same as unsetting. Likewise, it is not possible to set a DUIDType=0. If it ever becomes necessary to set type=0 or a zero-length duid, the code can be changed to support that. Nevertheless, I think that's unlikely. This addresses #3127 § 1 and 3. v2: - rename DUID.duid, DUID.duid_len to DUID.raw_data, DUID.raw_data_len
2016-05-03dh-dhcp{,6}-client: change the semantics of DUID settingZbigniew Jędrzejewski-Szmek
Both versions of the code are changed to allow the caller to override DUID using simple rules: duid type and value may be specified, in which case the caller is responsible to providing the contents, or just duid type may be specified as DUID_TYPE_EN, in which case we we fill in the values. In the future more support for other types may be added, e.g. DUID_TYPE_LLT. There still remains and ugly discrepancy between dhcp4 and dhcp6 code: dhcp6 has sd_dhcp6_client_set_duid and sd_dhcp6_client_set_iaid and requires client->state to be DHCP6_STATE_STOPPED, while dhcp4 has sd_dhcp_client_set_iaid_duid and will reconfigure the client if it is not stopped. This commit doesn't touch that part. This addresses #3127 § 2.
2016-04-29networkd: rework headers to avoid circular includesZbigniew Jędrzejewski-Szmek
Header files were organized in a way where the includer would add various typedefs used by the includee before including it, resulting in a tangled web of dependencies between files. Replace this with the following logic: networkd.h / \ networkd-link.h \ networkd-ipv4ll.h--\__\ networkd-fdb.h \ networkd-network.h netword-netdev-*.h networkd-route.h \ networkd-netdev.h If a pointer to a structure defined in a different header file is needed, use a typedef line instead of including the whole header.
2016-04-29networkd: clean up DUID code a bitLennart Poettering
Let's move DUID configuration into the [DHCP] section, since it only makes sense in a DHCP context, and should be close to the configuration of ClientIdentifier= and suchlike. This really shouldn't be a section of its own, we don't have any for any of our other per-protocol specific identifiers... Follow-up for #2890 #2943

2016-04-20networkd: bump MTU to 1280 for interfaces which have IPv6 enabled (#3077)Susant Sahani
IPv6 protocol requires a minimum MTU of 1280 bytes on the interface. This fixes #3046. Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled. Introduce network_has_static_ipv6_addresses() to find out if any static ipv6 address configured. If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static IPv6 addresses not configured, then IPv6 will be automatically disabled for that interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.
