Re: Inconsistent escaping of regex parentheses

(First of all, apologies if the formatting of this email formatting isn’t 100% - it’s been a while since I replied to an archived email post on a mailing list and it would appear that using a web based client is a pretty horrific experience out of the box..) >> I'm in the process of upgrading an old 2.2.0 installation of >> FreeRADIUS to a more sane 3.0.17 release (stock from current CentOS). > > That's good, but 3.0.20 is available from our web site: Fair point.. I’ve moved onto the 3.0.20 build while investigating this. > What does the full debug log show? Using a fresh install of 3.0.20 on CentOS 8, I added the following Unlang procedure to the start of the authorise section within the default server; in order to trigger the behaviour: testRegex { update control { Tmp-String-0 = '@(DOMAIN1|DOMAIN2)$' } if ( &User-Name =~ /%{control:Tmp-String-0}/i ) { update control { Tmp-String-1 = 'Yay!' } } } Results of the regex quoting are technically the same - but here the comparison simply fails rather than returning an error. — v3.0.20 - FreeRADIUS - Official repo (1) policy testRegex { (1) update control { (1) Tmp-String-0 = '@(DOMAIN1|DOMAIN2)$' (1) } # update control = noob (1) if ( &User-Name =~ /%{control:Tmp-String-0}/i ) { (1) EXPAND %{control:Tmp-String-0} (1) --> @\(DOMAIN1\|DOMAIN2)\$ (1) if ( &User-Name =~ /%{control:Tmp-String-0}/i ) -> FALSE (1) } # policy testRegex = noop The different error behaviour made me slightly curious, so I went back to a completely clean v3.0.17 CentOS deployment, used the same Unlang procedure as above - and the originally seen error is seen. — v3.0.17 - CentOS (1) # Executing section authorize from file /etc/raddb/sites-enabled/default (1) authorize { (1) policy testRegex { (1) update control { (1) Tmp-String-0 = '@(DOMAIN1|DOMAIN2)$' (1) } # update control = noop (1) if ( &User-Name =~ /%{control:Tmp-String-0}/i ) { (1) EXPAND %{control:Tmp-String-0} (1) --> @\(DOMAIN1\|DOMAIN2)\$ (1) ERROR: @\(DOMAIN1\|DOMAIN2)\$ (1) ERROR: ^ Pattern compilation failed: unmatched parentheses (1) ERROR: Failed retrieving values required to evaluate condition (1) } # policy testRegex = noop In both cases the regex fails as it is syntactically broken once escaping takes place.

Issue with building eapol_test for EAP-AKA testing with FreeRadius Server on MacOS Mojave
by Arindam Gupta (arindamg) 21 Jan '20

21 Jan '20

Hi, I need to build eapol_test from http://w1.fi/wpa_supplicant/ to use EAP-AKA simulator client with FreeRadius Server on my MacOS. However while trying to build I am getting some compilation errors. So would like to know if eapol_test supported on MacOS and if you are able to build it successfully on MacOS. Would appreciate any help on this. Thanks & Regards Arindam Gupta

FreeBSD 11.3-RELEASE-p5, freeRADIUS 3.0.20, openssl 1.1.1d -> segfault
by Ferdinand Goldmann 21 Jan '20

21 Jan '20

Hi, I am trying to upgrade a freeRADIUS installation running on FreeBSD 11.3 p5. This particular radius server connects to our LDAP load balancer using openssl. When compiling against the openssl port from the ports tree (1.1.1d) freeRADIUS crashes with a segmentation violation on startup. When compiling against openssl 1.0.2s (shipped with FreeBSD 11.3) the server starts up and processes requests just fine. Output when being run with -X (sensitive information X'ed out): # /usr/local/sbin/radiusd -X FreeRADIUS Version 3.0.20 Copyright (C) 1999-2019 The FreeRADIUS server project and contributors There is

capturing radius performance metrics
by Munroe Sollog 20 Jan '20

20 Jan '20

I would like to monitor the ongoing real-world performance of my freeradius server. In this case, I'm defining performance as time between receiving request and sending answer. I have used radsniff and radclient to do some benchmarking, but neither really seem like a sustainable or appropriate solution for long-term data collection in a production environment. Is there a way to add the "total response time" to the log line? or maybe there is a statistics channel like bind has to access performance metrics? I am able to collect a similar metric from the NAS as well as from some "fake" clients I configured to track radius authentication performance. I'm hoping there is a way to also gather this from the freeradius service directly. Thanks. -- Munroe Sollog Senior Network Engineer munroe(a)lehigh.edu

Authenticate users getting data from two different Data Sources
by Ja. C.A. 20 Jan '20

20 Jan '20

Hi list I 'd like to deploy FR to authenticate users, but I need FR to build the Authentication reply grabbing/merging info from two different data sources: - user/password checking -> from LDAP server - IP address assignment, DNS servers, etc -> from MySQL server Once FR has info from these two data sources, it should send the Access Reply... Is this config possible? Thanks in advance, M.

Inconsistent escaping of regex parentheses
by Tim 20 Jan '20

20 Jan '20

Hi all, I'm in the process of upgrading an old 2.2.0 installation of FreeRADIUS to a more sane 3.0.17 release (stock from current CentOS). I've hit a problem while trying to migrate the MySQL module due to the way that regular expressions seem to be getting escaped, and was hoping someone could see if anything looks amiss. We have a custom attribute, My-Regex-Pattern, that is defined as a simple string. In this instance, the attribute is held within the radgroupcheck MySQL table with the following regex stored as a string: @(.+\\.)?(DOMAIN1|DOMAIN2)$ During the authorize_check_query stage, a stored procedure is successfully called and the attribute is returned along with the correct value: (1) sql: Executing select query: Call getChecks('foo(a)bar.com'); (1) sql: User found in radcheck table (1) sql: Conditional check items matched, merging assignment check items (1) sql: My-Regex-Pattern := "@(.+\\.)?(DOMAIN1|DOMAIN2)$" However, when that string is later expanded via Unlang, the escaping appears to break as the opening parentheses get escaped while the closing ones do not: (1) if ( &control:My-Regex-Pattern && &User-Name =~ /%{control:My-Regex-Pattern}/i ) { (1) EXPAND %{control:My-Regex-Pattern} (1) --> @\(\.\+\\.)\?\(DOMAIN1|DOMAIN2)\$ (1) ERROR: @\(\.\+\\.)\?\(DOMAIN1|DOMAIN2)\$ (1) ERROR: ^ Pattern compilation failed: unmatched parentheses (1) ERROR: Failed retrieving values required to evaluate condition The error message makes perfect sense, but I'm unclear why this is happening and whether it's a misconfiguration, a bug or simply new intended behaviour that the migration needs to adapt to use. 'correct_escapes' is set to true and the sql modules 'safe_characters' option has been left as its default value. Thanks in advance. -- Tim

Can I retrieve session logs not registered in radacct?
by CESAR MURILO DA SILVA JUNIOR 19 Jan '20

19 Jan '20

Hello Are sessions recorded in the detail logs only after being recorded in the radacct and radpostauth table? I caused a lock on these tables and my boss asked me to retrieve the start and end times of the session by details, but there are only the records from before the transaction that caused the table locks.

Can I partition the radacct and radpostauh tables by month?
by CESAR MURILO DA SILVA JUNIOR 19 Jan '20

19 Jan '20

Hello, I went to delete the records with more than 30 days (there are 96 million currently) in radacct, and gave a table lock that stopped the wifi in the whole company. The delete was inside a transaction. I believe that if I partition the radacct and radpostauth tables I will be saved from this problem. Att *César Murilo da Silva Júnior* *Téc. Oper. Monit.

rlm_python learnings - PAP and MSCHAPv2
by Lang, Russell 18 Jan '20

18 Jan '20

FreeRADIUS is working, using rlm_python to do authentication for WPA2-Personal and WPA2-Enterprise Wi-Fi clients. This is a summary of the issues I found and suggested improvements. Using FreeRADIUS 3.0.15 package on Ubuntu 18.04. We previously had FreeRADIUS configured to exec a python process for each PAP or MSCHAPv2 authentication, which then called a REST API to check the user. This was slow (120ms) due to the time taken to start a process and load python. To speed this up, I first tried to use rlm_rest. This didn't work because we don't have the cleartext password, only the NT hash. Next I tried rlm_python, which I did get working. For PAP, during FreeRADIUS default authorize processing, it says no cleartext password, so it does not set Auth-Type=PAP, and so it does not call the PAP authenticate code. My workaround is python authorize code to set config:Auth-Type=python if User-Name and User-Password are set, but not EAP-Message. The default site config has "python" in the authorize section, and "Auth-Type python { python }" in the authenticate section. This is fragile, so if you have any better suggestions... For PEAP-MSCHAPv2, the default site config is unchanged. The inner-tunnel authenticate config has "Auth-Type mschap { python }". In the python authenticate code, I take the params and pass them to a REST API as JSON, then take the response from the REST API and return this as the reply. This means I am passing MS-CHAP-User-Name, MS-CHAP-Challenge and MS-CHAP2-Response into the API, and getting MS-CHAP2-Success as the reply. MS-CHAP-Challenge is in the expected format. Issue 1: MS-CHAP2-Response is NOT in the format defined in the RFC. The first byte is unknown. Second byte is the flag, moved from the end of the response, which is still wrong because it isn't 0. Subsequent bytes are as expected (16 bytes peer challenge, 8 bytes padding, 24 bytes NT response). I reformat the response to the RFC format before handing to the REST API. MS-CHAP-Response is also wrong in the same way, although the flag byte is the expected 1 (to indicate NT response is present). Issue 2: I generate the correct MS-CHAP2-Success packet "S=40hex" and include it in the python module reply. FreeRADIUS removes the first byte of this (source code confirms this) and sends the remainder, making it incorrect. My kludge is to add a padding byte at the start of the MS-CHAP2-Success python reply, for FreeRADIUS to remove. Suggestions: Have a fall-through authenticate method if Auth-Type is not set. This would avoid my fragile python authorize code, and allow PAP authentication without a cleartext password. Allow PAP authorize and rlm_rest to work if the NT hash of the password is available.
