[systemd-devel] [PATCH] Add FDB support

2014-12-11 Thread Alin Rauta 
Hi,

I've added support for handling the forwarding database table for a port.
FDB entries can be configured statically through the ".network" files.

To resume,
- I've added a new boolean for the main network structure, named 
"FDBControlled" which is read from the .network file and defaults to false.
- I've added a new section "FDBEntry" accepting 2 key-value pairs:
 -MACAddress (mandatory)
 -VLAN (optional)

When FDBControlled is set to "yes" in the network section, networkd:
- gets the FDB entries for current port;
- clears them
- configures those specified in the [FDBEntry] section.

Configuration example:

[Network]
DHCP=v4
FDBControlled=yes

[FDBEntry]
MACAddress=44:44:12:34:56:71
VLAN=9

[FDBEntry]
MACAddress=44:44:12:34:56:72
VLAN=10


Thanks,
Alin

[systemd-devel] [PATCH v2] Add FDB support

2014-12-15 Thread Alin Rauta 
Hi,

Based on your feedback, I've created a new patch for adding the FDB support.
networkd takes ownership of the FDB table.

Configuration example:

> cat /etc/systemd/network/em1.network

[Match]
Name=em1

[Network]
DHCP=v4

[BridgeFDB]
MACAddress=04:44:12:34:56:70
VLAN=2

[BridgeFDB]
MACAddress=04:44:12:34:56:69
VLAN=3

Let me know what you think.

Thanks,
Alin

[systemd-devel] [PATCH v3] Add FDB support

2014-12-17 Thread Alin Rauta 
Hi Tom,

I've formatted the patch based on our previous discussions. This one has 
support only for adding FDB entries.
An example configuration is like below:

[Match]
Name=em1

[Network]
DHCP=v4

[BridgeFDB]
MACAddress=44:44:12:34:56:71
VLANId=9

[BridgeFDB]
MACAddress=44:44:12:34:56:70
VLANId=2

Please let me know what you think.

Thanks,
Alin

[systemd-devel] [PATCH] Added UFD (Uplink failure detection) support to networkd

2015-01-23 Thread Alin Rauta 
Hi,

Uplink Failure Detection (UFD) is a key enhancement to networkd, that will 
provide support for the switch use case.
The links can be configured as uplinks or as downlinks inside an UFD group.
When all uplinks for a group are down, the failure is propagated to the 
downlinks, so the devices connected to them
can take a defined action. When at least one uplink become available, the 
daemon tries to bring the downlink ports up.

Multiple UFD groups can be configured through ".netdev" files. See below a 
configuration example:

[NetDev]
Name=group1
Kind=ufd

[UFDGroup]
Id=10

[UFDLink]
Name=sw0p1,sw0p2
Type=uplink

[UFDLink]
Name=sw0p3
Type=downlink

[UFDLink]
Name=sw0p4
Type=downlink


Few details on implementation:

Networkd waits until all links are enumerated (either static configured or 
unmanaged).
Only then it starts enumerating the groups.
"networkctl" command was also updated to support listing of ufd groups & 
configuration. See below a print-out:

# networkctl ufd 10
? UFD Group: 10
Config File: /etc/systemd/network/ufd_to_test.netdev
  State: configured
Uplinks:
   ? 3: sw0p1
   ? 4: sw0p2
  Downlinks:
   ? 6: sw0p4
   ? 5: sw0p3

Please let me know what you think.

Thanks,
Alin

[systemd-devel] [PATCH v4] Added support for Uplink Failure Detection using BindCarrier

2015-02-17 Thread Alin Rauta 
Hi,

I've creating patch v4 after addressing your comments.

I provided two APIs for networkctl command:
1. int sd_network_link_get_carrier_bound_to(int ifindex, char ***carriers);
2. int sd_network_link_get_carrier_bound_by(int ifindex, char ***carriers);

This way, only few changes were needed in "networkctl".

Only the "bound_by" links (uplinks) are monitored.
The "bound_by" map is evaluated only when the carrier is lost or gained.

When a link is added, its "bound_by" & "bound_to" maps are created.

When a link is dropped, both maps are removed.
When a link is readded, the maps are created again.

When a link is renamed, the old "bound_by" & "bound_to" maps are removed
and new ones are created taking into account the new name.

Let me know what you think,
Alin

[systemd-devel] [PATCH] libsystemd doesn't handle properly empty messages from kernel

2015-03-18 Thread Alin Rauta 
Hi,

Systemd strips out NLMSG_DONE piece from a multi-part message adding into the 
receive queue only the messages containing actual data.

If we send a request to the kernel for getting the forwarding database table 
(just an example),
the response will be a multi-part message like below:
1. FDB entry 1;
2. FDB entry 2;
3. NLMSG_DONE;

libsystemd strips out "3. NLMSG_DONE;" part and places into the receive queue a 
pointer to "1. FDB entry 1;".

But if the FDB table is empty, the respose from the kernel will look like below:
1. NLMSG_DONE;

libsystemd strips out "1. NLMSG_DONE;" part and since there is no actual data 
got, it continues waiting until reaching timeout.

Therefore, a call to "sd_rtnl_call" to send and wait for a response from kernel 
will exit with timeout
which is interpreted as error in communication.

The patch I've attached, adds "1. NLMSG_DONE;" to the receive queue only when 
getting empty response from kernel.
This way, a call like "sd_rtnl_call" will not block anymore.

It works fine, but it may be just an workaround. Let me know what you think.
