[RFC LNST 0/4] create functions without logic in run time
by Nogah Frankel
When one want to add a new function to the slave, one needs to add it also
to the slave communicator (NetTestSlave), and to the controller side that
control it (Macine) and to Task, that controls it.
While some of this functions have logic, most of them are just calling a
function of an object that they holds, usually, with the same name.
Those function can, and I think they should, be manufactured in run time
for the following reasons:
* it shorten the code considerably (new code is 25% of the old one).
* it makes adding new function much shorter.
* it singles out the function that do have logic in them.
There are however some down sides to it:
* code is a bit harder to read at first.
* Inheriting function is a bit more tricky.
This is just a start and it can be expanded for:
* more classes with functions with this problem
* setter-getters without inner logic
* function with arguments with default values
I know that LNST is now in freeze and I don't know how much of it will be
relevant after it. But in case it is, I will be glad to hear your
opinions on it in the meantime.
Nogah Frankel (4):
Machine: Interface: create RPC calls functions in run time
Slave: NetTestSlave: SlaveMethods: create dev functions calls in run
time
Slave: NetTestSlave: SlaveMethods: create bridge function calls in run
time
Task: InterfaceAPI: create interface calls functions in run time

[PATCH 0/5] Add switchdev SPAN recipe
by Yotam Gigi
Add the SPAN port mirroring recipe for switchdev, and several lnst
features that were missing and were needed for that recipe.
Among the features added:
- The lnst slave now cleans the tc qdiscs and filters at the clean
procedure.
- The PacketAssert module supports setting promiscuos flag.
- The Switchdev TestLib IcmpPing module supports setting ping
parameters.
The SPAN recipe consist of two machines connected via a bridge in the
switch, and pinging each other, while ingress/egress port mirrors are
added and tested.
Yotam Gigi (5):
Controller: Task: Add documentation for one of the flags in run func.
switchdev: TestLib: Add controllable parameters to IcmpPing module.
PacketAssert: Add the promiscuous optional param.
Slave: Add basic support for tc.
recipes: switchdev: Add the SPAN recipe.

LNST upstream meeting reschedule
by Ondrej Lichtner
Hi,
we have an LNST upstream meeting scheduled for today, 15.00 - 16.00 CET
time. However I have to be in school during that so I'd like to
reschedule.
I'm ok with Tue, Wed, Thu for the same time slot, we can also move it to
Monday next week, or decide on a different time.
What works for you guys?

[PATCH] test_modules: fix cpu_util comparison in Netperf non-omni
output parsing
by Jan Tluka
Test module get_opt() returns string representation of None rather than
None value so we need to compare the attribute to 'None'. Without this
the module will always return failure and throughput value will be silently
ignored.
