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

• 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 default Visual Studio configuration for developers.
• Postgres can now automatically use alternate queries for errors other than duplicate keys.

• Mark rlm_unbound stable and add to packages. Patches by Nick Porter.
• Remove broken/unsupported Dockerfiles for centos8 and debian9.

• New optional "lightweight accounting-on/off" strategy. When refreshing queries.conf you should also add the new nasreload table and corresponding GRANTs to your DB schema.
• Add TLS-Client-Cert-X509v3-Certificate-Policies, which helps with eduroam. Suggested by Stefan Winter.
• Allow auth+acct for TCP sockets, too.
• Add rlm_cache_redis. See raddb/mods-available/cache for details.
• Allow radmin to look up home servers by name, too.
• Ensure that dynamic clients don't create loops on duplicates. Reported by Sam Yee.
• Removed rlm_sqlhpwippool. There was no documentation, no configuration, and the module was ~15 years old with no one using it.
• Marked rlm_python3 as stable.

• For rlm_linelog, when opening files in /dev, look at "permissions" to see whether to open them r/w.

Configuration changes

• correct_escapes has been removed, and is always set to "true" internally. Configuration changes may be required if you are using configurations from before 3.0.5. Other than this difference, 3.2.x is compatible with 3.0.x, and configurations from 3.0.x can be simply copied into a system running 3.2.x.

  already running instance.

• Fix off by one error that caused some MSCHAP-Error messages to
  be sent without the password change version (V=3) and the textual
  message component (M=).
• Always include C= V= and M= in MSCHAPv2 errors. RFC 2759 does not say
  that any of these fields are optional, and not including V= caused
  errors with wpa_supplicant.
• Do not include M= in MSCHAPv1 errors. It's not supported.

Feature improvements

• Make "pool" configurations more consistent, and
  update documentation for them.
• Move connection pool logic to "most recently started",
  instead of MRU. This should help with pool stability.
• More VSAs for 3GPP2
• Added examples of multi-value attributes to rlm_perl.
• LDAP-Group and SQL-Group attributes are now dynamically
  allocated.
• Only the "sql" module registers SQL-Group. Other instances
  register "instance-name-SQL-Group", similarly to "ldap".
• Unknown attributes are now complained about more often
  when used in unlang statements. e.g. if (Foo-Bar == 3)
  used to be a string to string comparison. It is now a
  parse error.
• Rename RLM_COMPONENT_* to MOD_* in the code.
  This makes many things easier.
• Move to C99 initializers for modules.
• Load modules in raddb/mods-enabled. This allows attributes
  like "LDAP-Group" to be used in the "files" module,
  without explicit ordering or listing in "instantiate".
• Added 'bootstrap' section to modules. Third-party modules
  will need to be updated.
• When adding clients from a DB, add them to a virtual server
  if that virtual server has a "listen" section. Otherwise,
  add the clients to the global list.
• When reading dynamic clients from a file, don't expire them
  if the underlying file is unchanged.
• Allow the server to originate CoA requests from the post-auth
  stage.
• The server creates ${run_dir} and ${logdir} in daemon mode,
  if they do not already exist.
• Add dictionary for Wi-Fi Alliance Hotspot 2.0. The server
  now supports all mandatory and optional attributes for this
  specification.
• HUP now re-loads the configuration only if the files have
  changed. If all files are unchanged, HUP re-opens the
  log file, and does nothing else.
• Much better debug messages for EAP-TLS, including which
  attributes are cached, and when they are retrieved.
• Increase default max_requests to 16384. Memory is cheap now.
• Added "stats memory" commands to radmin. Debug build only.
• Aptilo controller dictionary updates.
• SQL modules now use Acct-Unique-Session-Id everywhere.
• The redis modules are now stable.
• The LDAP module now supports SASL "interactive bind" method.
  This allows Kerberos based administrator and user binds.
