The kernel always returns all addresses, rather than only for the given link, so let's only enumerate once.
|
|
This allows the default link settings (set in .link files) to be overridden per Network. Only MTU and MACAddress is supported for now.

This patch add support to specify path cost of the
bridge port to be configured via conf file.
Exampe: conf
file: br.netdev
[NetDev]
Name=br-test
Kind=bridge
file: br.network
[Match]
Name=em1
[Network]
Bridge=br-test
[BridgePort]
Cost=332
bridge link
2: em1 state UP : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master
br-test state disabled priority 32 cost 332

V3: fix copy paste error
V4: Make manual and config more readable
Add vxlan paramertes to config.

- Rename log_meta() → log_internal(), to follow naming scheme of most
other log functions that are usually invoked through macros, but never
directly.
- Rename log_info_object() to log_object_info(), simply because the
object should be before any other parameters, to follow OO-style
programming style.

log_error_errno() as log calls that take error numbers
This change has two benefits:
- The format string %m will now resolve to the specified error (or to
errno if the specified error is 0. This allows getting rid of a ton of
strerror() invocations, a function that is not thread-safe.
- The specified error can be passed to the journal in the ERRNO= field.
Now of course, we just need somebody to convert all cases of this:
log_error("Something happened: %s", strerror(-r));
into thus:
log_error_errno(-r, "Something happened: %m");

Now that we only have one file with condition implementations around, we
can drop the -util suffix and simplify things a bit.

187fe1db took advantage of floating events, but didn't remove pointers
it made superfluous.

This lets the routing metric for links to be specified per-network,
still defaulting to DHCP_ROUTE_METRIC (1024) if unspecified. Hopefully
this helps with multiple interfaces configured via DHCP.
|
|
This makes DHCPv4 and IPv4LL coexist peacefully.
[tomegun: apply to both the dhcp routes, use in_addr_is_null() rather than a
separate variable to indicate when prefsrc should be applied]

This allows the search/routing domanis to be specified per link/network and be passed
on to resolved.
|
|
This option will also apply to the search domains, so make it plural.
|
|
|
|
|
|
And inform the DHCPv4 clients about it.

This is necessary for non-ipv4ll hosts to communicate with ipv4ll-only hosts on the same link. Defaults
to being enabled, but can be opted out.
See: <http://avahi.org/wiki/AvahiAutoipd#Routes>
|
|
In the state files, do not distinguish where the various entries came from
(static or DHCP), but include them all in the same list.

All routes added by networkd are currently set RTPROT_BOOT, which according
to the kernel means "Route installed during boot" (rtnetlink.h). But this
is not always the case as networkd changes routing after boot too. Since
the kernel gives more detailed protocols, use them.
With this patch, user-configured static routes now use RTPROT_STATIC (which
they are) and DHCP routes use RTPROT_DHCP. There is no define for IPv4LL
yet, so those are installed as RTPROT_STATIC (though perhaps RTPROT_RA is
better?).

Let's settle on a single type for all address family values, even if
UNIX is very inconsitent on the precise type otherwise. Given that
socket() is the primary entrypoint for the sockets API, and that uses
"int", and "int" is relatively simple and generic, we settle on "int"
for this.

It appears there is no good way to decide whether or not broadcasts should be enabled,
there is hardware that must have broadcast, and there are networks that only allow
unicast. So we give up and make this configurable.
By default, unicast is used, but if the kernel were to inform us abotu certain
interfaces requiring broadcast, we could change this to opt-in by default in
those cases.

Split each netdev kind into its own .h/.c.

Enslave only really makes sense when referring to bridges and bonds, so try to be
a bit more neutral.

Vendor Class Identifier be used by DHCP clients to identify
their vendor type and configuration. When using this option,
vendors can define their own specific identifier values, such
as to convey a particular hardware or operating system
configuration or other identifying information.
Vendor-specified DHCP options—features that let administrators assign
separate options to clients with similar configuration requirements.
For example, if DHCP-aware clients for example we want to separate
different gateway and option for different set of people
(dev/test/hr/finance) in a org or devices for example web/database
servers or let's say in a embedded device etc and require a different
default gateway or DNS server than the rest of clients.

Now route metric can be configuted via conf file:
example conf:
[Match]
Name=em1
[Route]
Gateway=192.168.1.12
Metric=10
Test:
ip route output
default via 192.168.1.12 dev em1 metric 10
[tomegun: squash TODO update and reword man page a bit]

private in-addr-util.[ch]
These are enough calls for a new file, and they are sufficiently
different from the sockaddr-related calls, hence let's split this out.

This patch adds supports networkd to configure bond mode
during creation via persistent conf. Mode can be configured
with conf param 'Mode'. A new section Bond is added to the
conf to support bond mode.
These modes can be configured now.
balance-rr
active-backup
balance-xor
broadcast
802.3ad
balance-tlb
balance-alb
Example conf file: test-bond.conf
[NetDev]
Name=bond1
Kind=bond
[Bond]
Mode=balance-xor
Test case:
1. start networkd service:
12: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc
noqueue state UNKNOWN mode DEFAULT group default
link/ether 22:89:6c:47:23:d2 brd ff:ff:ff:ff:ff:ff
2. find bond mode:
cat /proc/net/bonding/bond1
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: load balancing (xor)
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0
Changes:
1. Added file networkd-bond.c
2. Bond mode enum BondMode
3. conf section [Bond]

This patch adds peer address support for
networkd . In the [Address] a new configurable
param is Peer.
[Match]
Name=ipip-tun
[Address]
Address=10.0.0.1/32
Peer=10.0.0.2/32
|
|
It had a bug in the typing, fix that and also make it save the address family so we
can print proper error messages.

This patch introduces TUN/TAP device creation support
to networkd.
Example conf to create a tap device:
file: tap.netdev
------------------
[NetDev]
Name=tap-test
Kind=tap
[Tap]
OneQueue=true
MultiQueue=true
PacketInfo=true
User=sus
Group=sus
------------------
Test:
1. output of ip link
tap-test: tap pi one_queue UNKNOWN_FLAGS:900 user 1000 group 1000
id:
uid=1000(sus) gid=10(wheel) groups=10(wheel),1000(sus)
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
Modifications:
Added:
1. file networkd-tuntap.c
3. netdev kind NETDEV_KIND_TUN and NETDEV_KIND_TAP
2. Tun and Tap Sections and config params to parse
conf and gperf conf parameters
[tomegun: tweak the 'kind' checking for received ifindex]

Send hostname (option 12) in DISCOVER and REQUEST messages so the
DHCP server could use it to register with dynamic DNS and such.
To opt-out of this behaviour set SendHostname to false in [DHCP]
section of .network file
[tomegun: rebased, made sure a failing set_hostname is a noop and moved
config from DHCPv4 to DHCP]
|
|
The Link statemachine relies on this, as it would otherwise wait forever. Hook up the tunnels in the
same way as the other NetDev's.
|
|
This adds support for DHCP options 33 and 121: Static Route and
Classless Static Route. To enable this feature, set UseRoutes=true
in .network file. Returned routes are added to the routing table.
|
|
If there are v4 or v6 specific options we can keep those in separate sections,
but for the common options, we will use only one.
Moreovere only use DHCP=[yes/both|no/none|v4|v6] to enable or disable the clients.
|
|
Enable DHCPv6 support by creating a DHCPv6 boolean in the Network
section. Add necessary DHCPv6 structures and initial function calls.
|
|
When an address is configured to be all zeroes, networkd will now
automatically find a locally unused network of the right size from a
list of pre-configured pools. Currently those pools are 10.0.0.0/8,
172.16.0.0/12, 192.168.0.0/16 and fc00::/7, i.e. the network ranges for
private networks. They are compiled in, but should be configurable
eventually.
This allows applying the same configuration to a large number of
interfaces with each time a different IP range block, and management of
these IP ranges is fully automatic.
When allocating an address range from the pool it is made sure the range
is not used otherwise.

This patch enables netwokd to create vxlan
Changes:
Added:
1. File networkd networkd-vxlan.c
2. to netdev
bool learning
struct in_addr group
uint64_t vxlanid;
3. VXLAN subsection and config
parameters
|
|
Rename the netdev variables. Remove tunnel_
so that it can be reused .
|
|
It may sometimes be necessary to specify the MAC address of a netdev.
Let us set the correct one from the get-go, rather than having the
kernel generate a random one, and then change it after.
