Bug fixes

• Dynamic clients now inherit require_message_authenticator and limit_proxy_state from dynamic client {...} definition.
• Fix radsecret build rules to better support parallel builds.
• Checkpoint systems should be reconfigured for the BlastRADIUS attack: https://support.checkpoint.com/results/sk/sk182516 The Checkpoint systems drop packets containing Message-Authenticator, which violates the RFCs and is completely ridiculous.
• Fix duplicate CoA packet issue. #5397
• Several fixes in the event code
• Don't leak memory in rlm_sql_sqlite. #5392
• Don't stop processing RadSec data too early.

3.2.5

Configuration changes

• BlastRADIUS mitigations have been added to the "security" section. See require_message_authenticator and also limit_proxy_state.
• BlastRADIUS mitigations have been added to radclient. See man radclient, and the -b option.

Feature improvements

• Don't crash in debug mode when multiple intermediate certs are used Patch from Alexander Chernikov.

3.2.4

Configuration changes

• Better handle backslashes in strings in the configuration files. If the configuration items contain backslashes, then behavior may change. However, the previous behavior didn't work as expected, and therefore is not likely to be used.
• reject_delay no longer applies to proxied packets. All servers should now set reject_delay = 1 for security and scalability.
• %{randstr:...} now returns the requested amount of data, instead of one too many bytes.

Feature improvements

• Update EAP module pre_proxy checks to make them less restrictive. This prevents the "middle box" effect from affecting future traffic.
• Many fixes and updates for Docker images
• Add dpsk module. See mods-available/dpsk
• Print out what cause the TLS operations to be made, such as the EAP method name (peap, ttls, etc), or RADIUS/TLS listen / proxy socket.

• Fix multiple typos in MongoDB query.conf (#5130)
• Add define for illumos. Fixes #5135
• Add client configuration for TLS PSK.
• Permit originate CoA after proxying to an internal virtual server

• Fix crash with TLS Status-Server requests. Fixes #5326.

3.2.3

Configuration changes

• The rlm_ldap and rlm_sql modules now have a max_retries configuration item in the pool section. This sets a limit on how many times an operation will be retried if it fails indicating a connection issue.
• Added check_crl configuration to rlm_ldap. This only works with OpenSSL. Many Linux distributions use other TLS libraries, which won't work.
• Note that rlm_ldap does not support -= operators. The documentation disagreed with the code, so we fixed the documentation.
• If checkrad is called from SQL Simultaneous-Use checks it will now be passed NAS-Port-Id (as stored in the database), rather than NAS-Port.

Feature improvements

• Add max_retries for connection pools. Fixes #4908. Patch from Nick Porter.
• Update dictionary.ciena, dictionary.huawei, dictionary.wifialliance and dictionary.wispr; add dictionary.eleven.
• You can now list eap in the pre-proxy section. If the packet contains a malformed EAP message, then the request will be rejected. The home server will either reject (or discard) this packet anyways, so this change can only help with large proxy scenarios.
• Show warnings if libldap is not using OpenSSL.
• Support RADIUS/1.1. See https://datatracker.ietf.org/doc/draft-dekok-radext-radiusv11/ Disabled by default, can be enabled by passing --with-radiusv11 to the configure script. For now, this is for testing interoperability.
• Add extra sanity checks for malformed EAP attributes.
• More TLS debugging output
• Clear old module instance data before HUP reload. Avoids burst memory use when e.g. using large data files with rlm_files. Patch from Nick Porter.
• rlm_cache_redis is now included in the freeradius-redis packages.
• Separate out python2/python3 in Debian Packages. Previously python 2 or 3 was built depending on the system default which led to confusion. We now build both freeradius-python2 and freeradius-python3 packages where possible.

Bug fixes

• Don't leak MD contexts with OpenSSL 3.0.
• Increase internal buffer size for TLS connections, which can help with high-load proxies.
• Send Status-Server checks for TLS connections
• Give descriptive error if "update CoA" is used with "fake" packets, as it won't work. i.e. inner-tunnel and virtual home servers.
• Many small ASAN / LSAN fixes from Jorge Pereira.
• Close inbound RADIUS/TLS socket on TLS errors. When a home server sees a TLS error, it will now close the socket, so proxies do not have an open (but dead) TLS connection.
• Fix mutex locking issues on inbound RADIUS/TLS connections. This change avoids random issues with "bad record mac".
• Improve REST encoding loop. Patch from Herwin Weststrate. Closes #4950
• Correctly report the LDAP group a user was found in. Fixes #3084. Patch from Nick Porter.
• Force correct packet type when running Post-Auth-Type. Helps with #4980
• Fix small leak in Client-Lost code. Patch from Terry Burton. PR #4996
• Fix TCP socket statistics. Closes #4990
• Use NAS-Port-Id instead of NAS-Port during SQL simultaneous-use checks. Helps with #5010

3.2.2

Configuration changes

• The ldap module now supports setting cipher_list. See mods-available/ldap.
• Add connect_timeout for outgoing TLS sockets. Helps with #3501.
• Add config section for xlats in rlm_rest and an option to control REST body data encoding. Patches by Nick Porter.
• Allow Operator-Name and Called-Station-Id in attr_filter when proxying. Helps with less work in eduroam configurations.
• Ensure that the AcctUpdateTime field in SQL is always updated. This is so that we can track when the last packet arrived.
• Update the default configuration to reply to NAS when accounting proxying fails, but we still write to the detail file.

Feature improvements

• The configure process now gives a much clearer report when it's finished. Patches by Matthew Newton.
• Fallback to uname -n on missing hostname. Fixes #4771

• Add per-module README.md files in the source.
• Add default Visual Studio configuration for developers.
• Postgres can now automatically use alternate queries for errors other than duplicate keys.
• %{listen:TLS-PSK-Identity} is now set when using PSK and psk_query. This helps the server track the identity of the client which is connecting.

• Better error messages when %{listen:TLS-...} is used.
• Getting statistics via Status-Server can now be done within a virtual server. Fixes #4868
• Make TTLS+MS-CHAP work with TLS 1.3. Fixes #4878.
• Fix md5 xlat memory leak when using OpenSSL 3. Fix by Terry Burton.
