TCP vulnerability and its fix
There was a vulnerability discovered in the implementation of TCP in Linux (CVE-2016-5696) that is remotely exploitable and allows an attacker to impersonate a connected user. For a hotfix on a live system, you can add sudo sysctl net.ipv4.tcp_challenge_ack_limit=1000000000 to /config/scripts/vyatta-postconfig-bootup.script. The fix will be included in the 1.1.8 release.
Development meetup
Today at 18:00 UTC we will hold a development meeting, everyone is invited to join. It was discussed in phabricator (https://phabricator.vyos.net/Q41) originally, and most people voted for Google Hangouts, so that's what we'll use. I'm not fond of it myself, but so be it.
If you want to participate, fill the form here: https://goo.gl/forms/PBarp2bPWvAncQtJ2 so that we know your email address and can send you an invite.
It will be a semi-structured format, the agenda is the following:
- 1.1.8 maintenance release and what backports to include in it
- 1.2.0 and how to go about verifying that it actually works
- VyOS 2.0 (the clean rewrite) design principles
- Strategies for attracting more contributors
Rocket Chat
Lately we've setup Rocket Chat , an open source chat platform with some interesting features, including voice support, offline logs, and more. If it works well, we can use it for future development meetings, and possibly other things as well. If you want to give it a try, visit https://chat.vyos.io
1.2.0 beta2
People keep asking about 1.2.0-beta2. The truth is, if we build some image, and call it 1.2.0-beta2, nothing will change really. You can always get the latest nightly build from http://dev.packages.vyos.net/iso/current/amd64/ and start testing it. Maybe when it's stable enough for at least non-critical production environments, we will call it beta2, but until then, nightly builds is really a better way to go.
VyOS shirts
A bit to our surprise, there was some interest in VyOS shirts (https://teespring.com/stores/vyos), but they also created a bit of confusion as to what it costs and where the profit goes.
The base cost of the shirt around $15/EUR 10, so the "retail price" is some $5 higher than the base cost. Any profit from it will be used for things directly related to VyOS, such as domain renewals and the like (if the shirts somehow become popular enough to pay for anything else, we'll see what else we can do with it).
We need to come up with some convenient way to make the ledger public so that everyone can see what we received what it was used for.
