[DHCP Relay]: Support Multiple VLANs (Separate DHCP Relay Agents, One Per VLAN) #999

jleveque · 2017-09-28T23:54:32Z

- What I did

Spawn one DHCP relay agent for each VLAN that is configured as requiring one or more DHCP servers.
Also resolves Failed DHCP relay test #985

- How I did it

docker-dhcp-relay entrypoint is a new script, docker_init.sh, which is responsible for generating the supervisord configuration file dynamically from a Jinja2 template. docker_init.sh then starts supervisord via exec so that supervisord still runs as PID 1
Dynamically-configured supervisord config now supports spawning a variable number of DHCP relay agent processes, based on VLAN configuration
Due to above changes, we no longer rely on /etc/default/isc-dhcp-relay config file, so the related Jinja2 template and shell script have been removed
Update isc-dhcp-relay patch such that it no longer relies on calling sonic-cfggen to retrieve port aliases with each packet (slow). Now parses the aliases from port_config.ini file directly once at startup and loads them into memory
Prevent relaying of already-relayed packets using -m discard parameter
Change name of supervisord config file and template from generic supervisord.conf to more specific (albeit long) docker-dhcp-relay.supervisord.conf for better comprehension and also to avoid conflicts when copying to /usr/share/sonic/templates if we need to templatize other supervisord config files. We may also want to consider creating subdirectories under /usr/share/sonic/templates to further avoid other conflicts.
Update minigraph.py parser to parse out new <DhcpRelays> tag
Update sonic-cfggen test T0 minigraphs to contain new <DhcpRelays> tag
Remove executable permission and extra trailing newline from wait_for_intf.sh.j2 template file

- How to verify it

Generate a T0 minigraph with two or more VLANs, each configured with one or more DHCP servers (using the <DhcpRelays> tag.
Boot up SONiC using the minigraph created in step 1.
Verify that there are multiple dhcrelay processes running, one per VLAN as configured in step 1.
Verify that DHCP requests from devices on VLANs under the SONiC T0 are forwarded to all the DHCP servers configured in the minigraph, and verify all responses from DHCP servers are forwarded back to the appropriate device under the SONiC T0.

Seems that indenting does not match here?

Thanks. Looks like I wound up with tabs instead of spaces in all of the test minigraphs for some reason.

+{% if VLAN %}
+[group:isc-dhcp-relay]


If there are VLANs but non of them contains a "dhcp_server" attribute, there will be a [group: isc-dhcp-relay] with no programs specified. Will that work?

It does work, but it isn't the cleanest solution.

I could iterate all VLANs first and check whether any of them require a DHCP relay, but that adds more complexity to what is already a fairly complex template.

Well, it required 8 lines of code and 2 lines of comments to implement the check. I think it's still fairly readable, so I made the change, but I wish it could be simpler.

taoyl-ms · 2017-09-29T00:10:28Z

Does this mean DHCP_Server field in minigraph - device metadata will no longer be used?

jleveque · 2017-09-29T00:29:28Z

@taoyl-ms: Are you referring to the DhcpResources field?

taoyl-ms · 2017-09-29T00:32:02Z

Ah Yes.

jleveque · 2017-09-29T01:00:51Z

@taoyl-ms: The DhcpResources field is global for the device. The new <DhcpRelays> tag is a child of each VLAN, so this tag should be used to specify DHCP servers for each VLAN.

remove the commented lines?

I would have liked to leave them uncommented, but unfortunately, the behavior of log_debug() is to print to stdout, and we have configured supervisord to forward stdout messages to the syslog, so leaving these log_debug() calls in spams the syslog.

I considered removing these altogether, but they may come in handy for future debugging, so I thought leaving them commented out is better for posterity's sake than having to rewrite them again, even if it leaves a bit of clutter.

If you still prefer I remove them, I will. Just let me know.

we are going to forward the already relayed packet?

-m append|replace|forward|discard ?

how do you control the behavior for already relayed packet?

In reply to: 142012491 [](ancestors = 142012491)

I am preventing the relay of previously-relayed packets by limiting the max-hop-count to 1 (-c 1), under the assumption that we should only ever relay requests from devices immediately below the ToR (i.e., hop count of 0). If this assumption is incorrect, I will investigate the behavior of the -m flag.

it is better to give an option to specify which file to load. Also, you do not need to load port_config.ini file, you can use cfggen to generate your own port mapping file and load that port mapping file. In this case, we do not need to parse the port_config.ini, you can rely on cfggen's logic to get the correct port name mapping.

I considered that solution, but felt as though writing the output from cfggen to a file and reading that file back in was a bit excessive. However, it does prevent the need for maintaining a separate port_config.ini parser here.

That said, with my current solution, if the format of port_config.ini were to change, this parser would have to be updated. However, if we go with the cfggen solution you suggested and the cfggen output format ever changes, we would need to update the parsing of the cfggen output and the writing of the port mapping file here. I guess the decision comes down to the question: which format is less likely to change over time?

Done. Now parsing output from sonic-cfggen and writing to a file in docker_init.sh, then isc-dhcp-relay reads that file at startup. Also added file path as a parameter to isc-dhcp-relay.

They also cause fast-reboot not to meet timing requirements. In order to delay start those service are associated with systemd timer units, however when hostcfgd initiate service start, it start the service and not the timer. This PR fixes this issue by starting the timer associated with systemd unit. signed-off-by: Tamer Ahmed <tamer.ahmed@microsoft.com> * [sonic-py-common][multi ASIC] API to get a list of frontend ports (sonic-net#5221) * [sonic-py-common][multi ASIC] utility to get a list of frontend ports from a given list of ports * [sonic-config-engine] Update .gitignore (sonic-net#5223) - Ignore directories generated by building Python wheel package - Move all sonic-config-engine ignores from the root .gitignore to src/sonic-config-engine/.gitignore * Advance swss-common submodule.

The `ipv6_found` Jinja2 variable added to the supervisor config file goes out of scope before it is read. **- How I did it** 1. Rename the `wait_for_intf.sh` script to `wait_for_link.sh` 2. Use the Jinja2 "namespace" construct to fix the scope issue **- How to verify it** Ensure all processes in the radv container start properly under the correct conditions (i.e., whether or not there is at least one VLAN with an IPv6 address assigned). * [sonic-utilities] Update submodule (sonic-net#5233) * src/sonic-utilities d5fdd74...17fb378 (7): > [sonic-installer] Import re module (sonic-net#1061) > [fast-reboot]: Fix fail to execute fast-reboot problem (sonic-net#1047) > [config] Reduce Calls to SONiC Cfggen (sonic-net#1052) > [filter-fdb] Call Filter FDB Main From Within Test Code (sonic-net#1051) > [sflow_test.py]: Fix show sflow display.

The following is a non-exhaustive list of such functionality: Image management Configuration save and load ZTP enable/disable and status Show tech support - How I did it The host service is a Python process that listens for requests via D-Bus. It will then service those requests and send a response back to the requestor. This PR only introduces the host service infrastructure.

Zeroing this old relica makes sure that there is nothing left of the old partition lying around. There won't be any risk of having Aboot corrupt the new filesystem because of the old relica.

This fixes a bug where the file object returned from `mock_open()` was not iterable (see https://bugs.python.org/issue32933) - Add support for Python 3 setuptools and pytest in sonic-slave-buster environment - Add tests for `device_info.get_machine_info()` and `device_info.get_platform()` functions - Also add a .gitignore in the root of the sonic-py-common directory, move all related ignores from main .gitignore file, and add ignores for files and dirs generated by pytest-cov * Add switch for synchronous mode (sonic-net#5237) Add a master switch so that the sync/async mode can be configured. Example usage of the switch: 1. Configure mode while building an image `make ENABLE_SYNCHRONOUS_MODE=y <target>` 2.
