IPSEC failed to run after 2.4.4 upgrade
-
To anyone that can still reproduce this:
- Go to VPN > IPsec, Advanced tab.
- Under IPsec Logging Controls set strongSwan Lib to Highest, then Save
- Try to restart IPsec
- look in Status > System Logs, IPsec tab for a message about why it failed. Alternately, check
clog /var/log/ipsec.logfrom the shell.
The strongSwan source seems to imply that it could be a file/filesystem issue. The checksum is missing, the file size is wrong, or the checksum doesn't match. It could also be that somehow it can't find the library (Maybe run
ldconfigin the shell and then try starting it again).The debug logs will hopefully tell us more.
-
Here is the strongswan.conf (0_1541782634617_strongswan.conf.txt) from our running 2.4.3 that fails after upgrade.
I cannot reproduce now but will try the above of hours if nobody was able to provide before. -
One thing I did when upgrading was to refresh dashboard, because i thought that upgrade process freeze. Probably related with issue.

Probably not if the same thing happened after updating to 2.4.5.
Can you try the log changes I posted about a few replies up?
-
Sure, but I can do it Monday and get back with result.

I have opened https://redmine.pfsense.org/issues/9106 to track this, but we can't do anything until we can either reproduce it locally, or get the debug log messages stating exactly what part of the test failed.
After gathering the above info, I do have a hunch as it what might help. Install the system patches package and then try the following patch:
diff --git a/src/etc/inc/vpn.inc b/src/etc/inc/vpn.inc index d12eb986c2..c055a04d66 100644 --- a/src/etc/inc/vpn.inc +++ b/src/etc/inc/vpn.inc @@ -1556,6 +1556,7 @@ EOD; } /* manage process */ + mwexec("/etc/rc.d/ldconfig start", false); if ($restart === true) { mwexec("/usr/local/sbin/ipsec restart", false); } else {If that doesn't help, revert the patch.

Thanks for opening the issue for tracking.
Retried the update with the same problem. I changed the log level to highest as requested and started IPsec but it unfortunately did not report more information:Nov 11 23:56:33 ipsec_starter 19939 ipsec starter stopped Nov 11 23:56:33 ipsec_starter 19939 charon refused to be started Nov 11 23:56:33 ipsec_starter 19939 charon has quit: integrity test of libstrongswan failed Nov 11 23:56:33 ipsec_starter 19637 no known IPsec stack detected, ignoring!

Reverted back to 2.4.3 for now.
Let's see if dtrandov as better results. -
Did required changes, but no additional info in log files and IPsec refused to start.
Just for test i ran again pkg check -s strongswan, and some files are missing:

The man pages being missing is expected, as we normally will strip out the man pages and other docs from the host itself to save space.
I was hoping that little patch would help, but at least we know it isn't the library path.
If you can get a host back into the failed state, try going to an ssh or console shell prompt and then run this command:
ipsec stop ipsec start --debug-allAnd then check the console output and IPsec log
-
Console output:
ipsec stop:

OK, that is a different condition. It doesn't like a
.in the RADIUS server name. I didn't have any set that way, but now that I set one up I see the same error. Curious that the error is shown on the console but not in the logs. But now I do see the same integrity test error!So we're getting closer! Let me find a fix for this, most likely it will involve removing the dots or swapping them for some other character.
-
Great.
well, I've just defined new radius server entry (without dots in name) in System/User Manager/Authentication Servers and IPSec is up now..... definitely dots in name are problematic.
-
Thankfully that is a very simple fix (assuming you don't fudge the regex like I did on my first commit), so if you want to keep a RADIUS server entry with
.in the name, you can if you apply the following patch:diff --git a/src/etc/inc/vpn.inc b/src/etc/inc/vpn.inc index 2458a224f5..e3ccb4f3c4 100644 --- a/src/etc/inc/vpn.inc +++ b/src/etc/inc/vpn.inc @@ -478,7 +478,7 @@ EOD; $user_sources = explode(',', $config['ipsec']['client']['user_source']); foreach ($user_sources as $user_source) { $auth_server = auth_get_authserver($user_source); - $nice_user_source = strtolower(preg_replace('/\s+/', '_', $user_source)); + $nice_user_source = strtolower(preg_replace('/[\s\.]+/', '_', $user_source)); if ($auth_server && $auth_server['type'] === 'radius') { $radius_server_txt .= <<<EOD {$nice_user_source} { -
Thanks a lot. Really appreciate you assistance :)

Thanks jimp!
I'll try this also tonight and post results.
Quick question: (I'm no expert with diff.) Shouldn't the path in the above patches be /etc/inc/vpn.inc? There is no /src folder on our system.
Also, will this be corrected is a future release or will we need to keep the patch as long as we have names with dot? -
It will be corrected in 2.4.4-p1 and 2.4.5.
As for the path, the system patches package defaults to a path strip level of 2, so it will do the right thing here.
The source in github has a
src/directory prefix, which is why it shows in patches made from git commits like the above. -
Understood for the default strip level of the system patches package.
This worked also for us and we now have a working 2.4.4 system.
Thanks jimp!
