[AclOrch] aclOrch enhancement to handle LAG port not configured case #494

keboliu · 2018-05-04T09:47:25Z

What I did

Add STATE_DB db connector to Orchdaemon so AclOrch can use it.
AclOrch subscribe to STATE_DB and handle the LAG add/del notificaiton from STATE_DB.
When AclOrch detected a LAG port in it's port list not configured yet, it will continue to handle the rest ports in the list and add this LAG port to the pending port list.
When AclOrch received the LAG port created notification, and this LAG is in it's pending list, it will bind the ACL table to this LAG.
If one LAG deleted, the related ACL table that have this LAG, will add this LAG to the pending port list.

Why I did it
it's possible that LAG port configured later or not configured yet while ACL table created, in this case we can add this LAG to the pending list and wait for it created, instead of fail the whole ACL table creating.

How I verified it
manual test, run ACL and Everflow test case on T1 and T1-LAG topo.

@qiluo-msft Hi Qi, could you elaborate the concern here? #Closed

There are several 'new' statements here. If memory is used up in the middle, there will be memory leak issue.
The bug should be here for a long time, and your added code make it worse a little bit.

Sorry, I mean processPorts() and processPendingPort() share some code, it is possible to call one from the other?

In reply to: 186252087 [](ancestors = 186252087)

@qiluo-msft They do share some same code, I also have considered calling processPendingPort(previously processSinglePort) in processPorts. But if we look into the whole procedure, processPorts only "link" ports to tables and the action to "bind" table to ports are not included.
For processPendingPort, it's dedicated to receiving the notification and handle the pending port, in this one function "link" and "bind" all performed. To keep the code more straightforward and readable I decide to have these two functions separated through will have some slight redundant code.

you can move aclTable.bind out of the processPendingPort() function and make the code reuse.

you can do aclTable.bind in doAclTablePortUpdateTask().

-    OrchDaemon *orchDaemon = new OrchDaemon(appl_db, config_db);


I don't think we would need to have orchDaemon allocate from stack. This could still be retained as it is (allocate via new) so we wouldn't have to worry about the class holding more data in future just in case.

It could be a normal flow to delete aclTable which is not yet bind to any port list. We wouldn't want to log warning if it is in the delete flow.

Please also get Prince's approval.

Changes looks good. Could you please add/update VS test cases for ACL to verify this changes?

liatgrozovik · 2018-05-10T08:18:29Z

As for VS, it should be added but for now we have the testbed to cover this flow.
Lets please approve the change and we will add new VS cases for port channel.
It is currently don't have any reference to port channel although it was supported before.

lguohan

need vs switch test.

3 new VS test case added

negative test: bind acl table to lag member port
bind acl table to lag
bing acl table to non-exist lag and then configure this lag.

what is the scenario here? when a port is removed, then to update the acl table? In this case, you need to unbind the port from acl table, and then put the port to pending list. You cannot simply put the port into the pending list.

for this one maybe need to marked as TODO here. if one port or LAG deleted, do will still have the chance to unbind it? I mean maybe some DB entries already destroyed and for SDK level all the configuration should already be cleared?

move this after port channel member creation, before state db creation.

verify_acl_group_member [](start = 13, length = 23)

this function signature should be

verify_acl_group_member(adb, [acl_group_ids], acl_table_id)

it should verify the acl_groups have corresponding acl_group_member which has the acl_table_id.

verify_acl_lag_binding(self, adb, expt): [](start = 8, length = 40)

like the verifying the port binding, we need to give the lag name as input.

I didn't find out how a lag port name
was mapped to a SAI_OBJECT_TYPE_LAG_MEMBER in ASIC DB, unless you create one LAG and then know that the only SAI_OBJECT_TYPE_LAG_MEMBER record in ASIC DB is yours?

use lag_object_ids here instead of lag name.

you do not need give expt here, just use the len(bind_ports)

change to bind_ports as well, do not need expt here.

for lag case it different with port case, bind_ports len may not equal to the binding lag number if some LAG not configured yet, so I think we still need a expt?

getValidPortId [](start = 20, length = 14)

to reflect the true meaning, it is better to rename it to getBindPortId. Besides, it makes more sense to move this into portsyncd since it is retrieving a port property.

renamed and move it to portOrch.
