Patching/Upgrading OpenSSL

@joltman:

I just saw some people in the forum are getting an error when they're editing their rules. I'm going to hold off for now.

2.1.2 installed, working for me. Joltman: what's your IP address? …..

@joltman: As I was reporting this, I agree to adams statement. Getting rid of autoconfbackup package before upgrading should completely avoid this. Afterwards it can be installed to it's new version (1.22) again without hiccups. Problem was completely related to the package, not the main distro.

Cool. I'm proceeding. Poor ESF servers getting hammered hard.

EDIT: Finished. Looks good!

Hi all, I see the founder tweeted that keys may be OK:

However I also know that people have pulled keys from FreeBSD. For OpenVPN users, do we need to swap our keys if we were using PFsense 2.1.x?

Thanks.

Thanks for getting 2.1.2 out!

This will be my first upgrade. I assume the firewall will need to reboot. Any quick advice or how long an upgrade takes, how long is the downtime, maybe these questions are already covered somewhere?

Does the secondary firewall upgrade when it sees it peer upgrade or do I trigger that manually?

I've announced 5+ minutes downtime in a 1 hour maintenance window. Looks like there's a backup / rollback option so I'm hoping that even if I hit a snag I won't be dead in the water!

Thanks,

Upgraded one of my boxes from 2.0.3 to 2.1.2.

No issues to report! ;)

Except that Suricata lost all of its interface settings. Looks like a new install of that package. Snort was also installed and it came back 100%

Great Work Guys!

What testing method is recommended to test the Bleeding Heart issue in pfSense?

I registered just to comment on what an amazing job you guys did in getting this patch out so quickly. There are commercial routers costing hundreds of dollars (if not thousands) that I imagine will be vulnerable for weeks…

Thank you Jim Pingle, Chris Buechler, all the other devs and the community members that helped make this happen! It's much appreciated!

I will be buying a gold subscription to show my thanks!

@dannyman:

Any quick advice or how long an upgrade takes, how long is the downtime

It took my pfSense box about 5-10 minutes for the whole process (which was without any problems).
The downtime was only 1 minute 30 seconds (the time I couldn't access internet or ping the pfSense box). My pfSense box is quite an old PC (Pentium 3 or 4).

Thank you admins for your work on this serious bug.

You're using CARP on all interfaces? If so, the downtime will be basically zero.

Upgrade the backup first. Once it's back up and running disable CARP on the first box to force a failover. Once you're sure things are working on the backup, upgrade the primary. Once the upgrade is done everyone will fail back to the primary automatically.

What about windows OpenVPN client programs? I have to upgrade them too or not?

Happily my "system where VPN runs and security matters" is still on 2.0.3, as I've I've had continuing nags with 2.1 where I did try it that made me not upgrade that one since 2.0.3 is nice and stable and I can put up with complaints from the users of the other system more easily as I try to work the 2.1 issues out there (or wait for them to be worked out, more likely.) Hopefully 2.1.2 will be better than 2.1, and if not, I guess there's always heading back to 2.0.3 on both systems.

Unless you are dependent on packages being installed like some routing daemons, squid, etc. The current disable carp feature on the carp status page does not survive reboots. The primary will take over immediately after the reboot before those get re-installed fully so there will be some downtime in that case. If you don't depend on any packages then it should be 0 downtime.

Someone has submitted a feature in 2.2 version that allows you to put a carp member in maintenance mode so that the member you put into maintenance mode will not take over when it boots up unless carp detects that the other member is down.

See several OpenVPN connections from an unauthorized location in the firewall logs this morning.
Is this someone trying to exploit the Heartbleed bug?
