14 directives for the same address:port, or NameVirtualHost
15 directives with no matching VirtualHosts, or multiple ip-based
16 VirtualHost sections for the same address:port. These were
17 previously accepted with a warning, but the behavior was

104 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
105 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
106 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability

108 support the new secure renegotiation protocol, RFC 5746.
109 [Joe Orton, and with thanks to the OpenSSL Team]
111 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
112 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
113 by rejecting any client-initiated renegotiations. Forcibly disable
114 keepalive for the connection if there is any buffered data readable. Any
115 configuration which requires renegotiation for per-directory/location
116 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.

133 *) core: Adjust the output filter chain correctly in an internal
134 redirect from a subrequest, preserving filters from the main
135 request as necessary. PR 17629. [Joe Orton]
137 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
138 Response if they so choose to do so. Previously an attempt to cache a 206
139 was arbitrarily allowed if the response contained an Expires or
140 Cache-Control header, and arbitrarily denied if both headers were missing.
143 *) core: Add microsecond timestamp fractions, process id and thread id
144 to the error log. [Rainer Jung]

167 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
169 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
172 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
173 title page only) when any mod_ldap directives were used in VirtualHost
174 context. [Eric Covener]
176 *) mod_disk_cache: Decline the opportunity to cache if the response is
177 a 206 Partial Content. This stops a reverse proxied partial response
178 from becoming cached, and then being served in subsequent responses.
181 *) mod_deflate: avoid the risk of forwarding data before headers are set.

1142 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
1143 parameters to the environment. Improve portability to
1144 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
1146 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
1147 to authorize an authenticated user via a "require ldap-group X" directive
1148 where the user is not in group X, but is in a subgroup contained in X.

1153 *) apxs: Enhance -q flag to print all known variables and their values
1154 when invoked without variable name(s).

1160 *) beos MPM: Create pmain pool and run modules' child_init hooks when
1161 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
1164 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
1165 cleanups registered in modules' child_init hooks are performed.
1168 *) Fix issue which could cause error messages to be written to access logs
1169 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
1171 *) The LockFile directive, which specifies the location of
1172 the accept() mutex lockfile, is deprecated. Instead, the
1173 AcceptMutex directive now takes an optional lockfile
1174 location parameter, ala SSLMutex. [Jim Jagielski]
1176 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1177 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1178 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1180 *) mod_dbd: Key the storage of prepared statements on the hex string
1181 value of server_rec, rather than the server name, as the server name
1182 may change (eg when the server name is set) at any time, causing
1183 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1185 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1187 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1188 the first bucket from the brigade, finds it not to be a FILE
1189 bucket and barfs. The fix is to pass a bucket rather than a brigade.

1192 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1194 *) ap_get_server_version() has been removed. Third-party modules must
1195 now use ap_get_server_banner() or ap_get_server_description().
1198 *) All MPMs: Introduce a check_config phase between pre_config and
1199 open_logs, to allow modules to review interdependent configuration
1200 directive values and adjust them while messages can still be logged
1201 to the console. Handle relevant MPM directives during this phase
1202 and format messages for both the console and the error log, as
1203 appropriate. [Chris Darroch]
1205 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1206 to circumvent the symbolic link checks imposed by FollowSymLinks and
1207 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1209 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1210 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1211 The default is none as this is far greater debugging resolution than

1238 *) mod_charset_lite: Remove Content-Length when output filter can
1239 invalidate it. Warn when input filter can invalidate it.
1242 *) Authz: Add the new module mod_authn_core that will provide common
1243 authn directives such as 'AuthType', 'AuthName'. Move the directives
1244 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1245 into mod_authn_core. [Brad Nicholes]
1247 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1248 into the new module mod_access_compat which can be loaded to provide
1249 support for these directives.
1252 *) Authz: Move the 'Require' directive from the core module as well as
1253 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1254 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1255 logic into the authorization processing. [Brad Nicholes]
1257 *) Authz: Add the new module mod_authz_core which acts as the
1258 authorization provider vector and contains common authz
1259 directives. [Brad Nicholes]
1261 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1262 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1264 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1265 host-based access control provided by mod_authz_host and invoked
1266 through the 'Require' directive. [Brad Nicholes]
1268 *) Authz: Convert all of the authz modules from hook based to
1269 provider based. [Brad Nicholes]
1271 *) mod_cache: Add CacheMinExpire directive to set the minimum time in

1280 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1282 *) Added an End-Of-Request bucket type. The logging of a request and
1283 the freeing of its pool are now done when the EOR bucket is destroyed.
1284 This has the effect of delaying the logging until right after the last
1285 of the response is sent; ap_core_output_filter() calls the access logger
1286 indirectly when it destroys the EOR bucket. [Brian Pane]
1288 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1289 and the format of statistical output has changed. [Colm MacCarthaigh]
1291 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1293 *) Added new connection states for handler and write completion
1296 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1299 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1300 allowing string-valued client certificate attributes to be used for
1301 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
