Testing 3.0/master
by Phil Mayers 20 Oct '11

20 Oct '11

So, I've just compiled up the current "master", and a few things stand out. Using my existing 2.1.12 config: 1. EAP-TTLS/MSCHAP doesn't seem to work any more; the MS-CHAP challenge/response are wrong. PEAP works fine. Haven't looked into this yet. 2. rlm_eap_tls now mandates "private_key_password" even if the key is not encrypted on disk. You can specify anything - but you must specify it. Behaviour change, but not particularly onerous. 3. Fast Session resumption seems to give a segfault - request_finish calls pairfree on process.c:1085 and the value seems to be corrupt. The backtrace is a bit useless, since most of the values are optimised out (grr gcc) but I will try to get more info. Will follow up with more as I figure out the cause(s)

EAP-TLS & authorize & LDAP -> non-sane default
by Stefan Winter 20 Oct '11

20 Oct '11

Hello, some admins who deploy EAP-TLS brought an interesting note to my attention (can't actually verify it, as I don't have their sophisticated setup)... The story goes like that - EAP-TLS does not have inner EAP, so there is no inner virtual server for it - if you want to authorization checks for the user, it has to happen on outer server (say, ask LDAP for some user attributes) - the default ldap filter expression uses (Stripped) User-Name - User-Name in EAP-TLS can be set arbitrarily by the end user as outer identity -> FreeRADIUS by default performs authorisation checks with an unvetted, user-supplied string So, if John Doe has a valid certificate, but is not authorized for network access, but he knows that Jane Donk *is* authorized, he could set anon ID = Jane Donk, and use his own certificate. authorize passes with Jane's User-Name, and authentication passes with John's proper certificate. That's all no tragedy; after all, it's just the *default* behaviour of the LDAP module, and can be changed. People may want to "channel bind" the two values on their own by enforcing User-Name == TLS-Client-Cert-Common-Name or so. I'm just wondering if we could by default ship a config which would prefer cert content, such as Common Name, over unvetted information so as to have a more sane default. I'm guessing that changing the ldap module's "filter" config item should do, from filter = "(uid=%{%{Stripped-User-Name}:-%{User-Name}})" to filter = "(uid=%{%{TLS-Client-Cert-Common-Name}:-%{%{Stripped-User-Name}:-%{User-Name}}))" (uh, I'm sure I got those curly braces wrong... bear with me...) That expression would do the same as before in all cases except when EAP types with Client TLS certificates are used, and would only then use the CN. Is there any sense in what I write?

Potential problems in 2.1.12 discovered by Coverity static source code scan
by John Dennis 19 Oct '11

19 Oct '11

We've started to perform static source code analysis on things we ship in the interest of trying to improve quality. We've been very impressed with the Coverity tools, they do an excellent job of finding problems. Coverity is not open source but they support open source projects by providing access to open source projects to some of their tools (you might consider registering with Covertiy). We have a Coverity license and have been granted permission to share our scan results with our upstream open source projects. We have just completed a scan on version 2.1.12 and I wanted to share the results. They are attached. Not every item flagged by the scan is meaningful, but we've learned by running the scans on our own code quite a bit of what is reported were actually undiscovered problems worth fixing. I recognize the timing would have been better if the scan had been performed prior to the release but we're still in the process of getting Coverity integrated into our tool chain. I wonder if the problems cropping up in 3.0 might be identified by a Coverity scan ... Hope this helps, John -- John Dennis <jdennis(a)redhat.com> Looking to carve out IT costs? www.redhat.com/carveoutcosts/

cert bootstrap script change: no more MD5?
by Stefan Winter 18 Oct '11

18 Oct '11

Hi, the bootstrap script uses ca.cnf, server.cnf and client.cnf for the generated certificates. All of these set the default_md = md5. iOS 5 is the first OS to condemn certificates which are signed by MD5. So, the default certificates generated by this script will not be compatible with recent iOS. Does anything speak against up'ing the default_md to sha1? Otherwise I can see questions on -user coming up saying EAP doesn't work - and this time with a particularly difficult to diagnose issue. Greetings, Stefan Winter

new rlm_sql connection pool logic
by Arran Cudbard-Bell 17 Oct '11

17 Oct '11

Hi All, Alan mercilessly ripped out all the connection pool logic in rlm_sql and replaced it with calls to the generic connection pool API which is new in 3.0. In anyone's running an SQL DB and wants to test it'd be much appreciated. New code is in Master@HEAD. WARNING: This change breaks compatibility with V2.0 configs, you will need an empty pool { } stanza in each instance of rlm_sql configuration or the server will fail to load. See here https://github.com/alandekok/freeradius-server/blob/master/raddb/modules/sql for the full pool configuration sub-section. The following configuration items no longer have any effect: num_sql_socks, connect_failure_retry_delay, lifetime, max_queries. Their equivalents are, (start, mix, max, spare), *none* , lifetime, uses. DEVELOPERS NOTE: From this point onwards any new modules which use a pool of connections, or would benefit from a pool of connections but doesn't use the connection API, will not be accepted. Code for connection pool is here: https://github.com/alandekok/freeradius-server/blob/master/src/main/connect… #include <freeradius-devel/connection.h> -Arran Arran Cudbard-Bell a.cudbardb(a)freeradius.org Betelwiki, Betelwiki, Betelwiki.... http://wiki.freeradius.org/ !

EAP Testing - Newbie
by Sergio NNX 16 Oct '11

16 Oct '11

Ciao all, First of all, I'm new to this project so I may ask 'dumb' questions and I may be slow to understand. Be patient! I'm in the process of testing FreeRADIUS 2.1.11, just basic/standard setup. I've been following the following user guide: http://deployingradius.com/documents/configuration/pap.html. Very useful, by the way. PAP, MSCHAP and MSCHAPv2 work ok, but I'm unable to get any EAP tests to pass. I've tries almost everything, including: http://deployingradius.com/documents/configuration/eap-problems.html I need some help! Thanks in advance. Sergio.

[libfreeradius-client] Send request to non-standard ports
by Kevin Lemonnier 05 Oct '11

05 Oct '11

Hi, I'm trying to send radius auth request to the 11812 port. So i've placed 11812 as second parameter of the rc_auth function. On my server's log, I can see that the NAS-PORT is set, in the request, to 11812. But the request itself is sent to the standard 1812 port .. How can I change that ? I need to send some request to 1812 and some others to 11812 (two radius servers are running). I've looked at the example code but they are just using the port parameter of rc_auth, so I can't find a way to make it work. (I'll need to do the same with accounting too) Thanks
