Jayapal and others - I've another one, is there a way to do routing without 
marking packets at all, even in case of VRs with additional public interfaces?

AFAIK marking is the only way to do it.
Do you have any performance numbers with and without mark rules.

Subject: [DISCUSS] Why we MARK packets?

All,


I could not find any history around 'why' we MARK or CONNMARK packets in mangle 
table in VRs? I found an issue in case of VPCs where `MARK` iptable rules 
failed hair-pin nat (as described in this PR: 
https://github.com/apache/cloudstack/pull/2514)


The valid usage I found was wrt VPN_STATS, however, the usage is not exported 
at all, it is commented:

https://github.com/apache/cloudstack/blob/master/systemvm/debian/opt/cloud/bin/vpc_netusage.sh#L141


Other than for debugging purposes in the VR, marking packets and connections I 
could not find any valid use. Please do share if you're using marked packets 
(such as VPN ones etc) outside of VR scope?


I propose we remove MARK on packets which is cpu intensive and slows the 
traffic (a bit), instead CONNMARK can still be used to mark connections and 
debug VRs without actually changing the packet marking permanently. Thoughts?

Re: [DISCUSS] Why we MARK packets?

[Rohit Yadav]

Hi Jayapal,


Thanks for replying. Can you point me to the code/rules that use the marking 
for packet routing (in case of additional public nics) in latest 4.11 or master 
branch? Don't we have routing tables and nat rules for routing across 
interfaces?


This started from reviewing Rafael's PR, whose fix I could not validate:

https://github.com/apache/cloudstack/pull/2514


I tested and found in my env that removing MARK rules in mangle table fixed 
access related issues for me, based on which I opened the PR:

https://github.com/apache/cloudstack/pull/2579


In case of VPC VRs and isolated network VRs, the nic number/order is different 
whose nic number/id is used to mark packets. I found that networking always 
failed when packets were marked with 0x1, but worked when 0x2 was used. I don't 
have an explaination for this. My test env was 4.11 based.

Hi,

Below are the uses of marking packets.

1. Marking is required to route the packets into correct interface in case 
additional public interfaces in VR.
2. Packets with VPN marking are accepted in first place of NAT POSTROUTING. 
Without marking these packets source ip will be replaced with source-nat IP.

Thanks,

Done. Site updated.

Re: Community opinion regarding Apache events banner in CloudStack's website

I wish that there was this much excitement about the problems in the 
installation docs!


Lets make a decision and live with layout for a few weeks and see how 
placement number 3 affects the community and how many people who did not 
plan to go to ApacheCon decide to go because of the placement of the 
event link.

Management of Transifex resources

[Rafael Weingärtner]

Hello Folks,
Today I was going to upload new keys to transifex and translate some
strings proposed in [1]. It looks a little messy the Transifex resources.
As I user, when I get there, I have no idea where I should work. Can we
have/use a single resource file there? If we only use the
“4.10_messages.json” now, can we delete others?

BTW: Do we know who has the admin account for the CloudStack organization
there?

Can we list the options and their voting numbers?  I am a bit confused
right now.

I like the one that is left aligned under the text and keeps the logo on
the right full size.
