|

- switch does not need to know about the "range", only about

sessions
|
||||
- on session create, controller selects "random" ip (ring?)
|
||||
- on session create, controller selects "random port" (next in range?)
|
||||
- on session create controller adds choice into 2 tables:
|
||||
incoming, outgoing

retrieving information from tables

\begin{verbatim}
|

Key and mask for matching destination is in table. We need this

we need to specify another parameter with the same information as in

|
||||
If I use LPM for matching, can I easily get the network address from P4 or do I have to use a bitmask myself? In the latter case it is not exactly clear how to get the mask from the table
|
||||
|
||||
Nate Foster [1:58 PM]
|
||||
You want to retrieve the address in the packet? In a table?
|
||||
And do you want to do the retrieving from the data plane or the control plane? (edited)
|
||||
|
||||
nico [2:00 PM]
|
||||
If I have a match in a table that matches on LPM, it can be any IP address in a network
|
||||
For calculating the NAT64/NAT46 translation, I will need the base address, i.e. network address to do subtractions/additions
|
||||
So it is fully data plane, what I would like to do
|
||||
I'll commit sample code to show the use case more clearly
|
||||
https://gitlab.ethz.ch/nicosc/master-thesis/blob/master/p4src/static-mapping.p4#L73
|
||||
GitLab
|
||||
p4src/static-mapping.p4 · master · nicosc / master-thesis
|
||||
gitlab.ethz.ch
|
||||
So the action nat64_static() is used in the table v6_networks.
|
||||
In v6_networks I use a match on `hdr.ipv6.dst_addr: lpm;`
|
||||
What I would like to be able is to get the network address ; I can do that manually, if I have the mask
|
||||
I can also re-inject this parameter by another action argument, but I'd assume that I can somewhere read this out from the table / match
|
||||
|
||||
Nate Foster [2:15 PM]
|
||||
To make sure I understand, in the data plane, you want to retrieve the address in the lpm pattern? (edited)
|
||||
|
||||
nico [2:16 PM]
|
||||
I want to retrieve the key
|
||||
|
||||
Nate Foster [2:16 PM]
|
||||
Wait. The value `hdr.ipv6.dst_addr` is the thing used in the match.
|
||||
So you have that.
|
||||
What you don’t have is the IPv6 address and mask put into the table by the control plane.
|
||||
I assume you want the latter, right?
|
||||
|
||||
nico [2:17 PM]
|
||||
For example, if my matching key is 2001:db8::/32 and the real address is 2001:db8::f00, then I would like to retrieve 2001:db8:: and 32 from the table
|
||||
exactly :slightly_smiling_face:
|
||||
I can "fix" this by adding another argument, but it feels somewhat wrong to do that
|
||||
Because the table already knows this information
|
||||
|
||||
Nate Foster [2:26 PM]
|
||||
I can’t think of a way other than the action parameter hack.
|
||||
|
||||
nico [2:26 PM]
|
||||
Oh, ok
|
||||
Is it because the information is "lost in hardware"?
|
||||
|
||||
Nate Foster [2:31 PM]
|
||||
No you’re right that most implementations have the value in memory. And one can imagine a different table API that allowed one to retrieve it in the data plane.
|
||||
But unless I am missing something obvious, P4 hides it…

Is there any meta information for "from which table was the action

called" available? My use case is having a debug action that sends
|
||||
packets to the controller and I use it as a default_action in various
|
||||
tables; however know I don't know anymore from which table the action
|
||||
was called. Is there any kind of meta information which table called
|
||||
me available?
|
||||
|
||||
I could work around this by using if(! .. .hit) { my_action(table_id)

It seems I was really mistaken for the last weeks
|
||||
If I am not totally mistaken, the following is happening with the netpfga:
|
||||
I was testing sending and receiving packets on the same computer; so I sent a packet on nfX and expected an answer on nf0, which is how I wanted to verify that the card works
|
||||
So I ran tcpdump on nf0, send a packet with ping6 and scapy on nf{0,1,2,3} (edited)
|
||||
I have never seen the switch emitting ANY packet back with tcpdump
|
||||
Now with the card connected to another host, sending neighbor solicitation, I see duplicated packets on the other host - so it seems that it might have worked all the time, just that tcpdump on nfX on the host which contains the card does not show the packets

generating the first python script (syntax ok, but content is

not correct) then a much later stage of the compile process will

fail due to a syntax error in the third generated

script. However that syntax error is not fatal in the build

process and thus can only be seen with careful analysis of the
