7 with the INCLUDES filter active, introduced in 2.4.11. PR 57531.
8 [Yann Ylavic]
9
10 *) SECURITY: CVE-2015-0228 (cve.mitre.org)
11 mod_lua: A maliciously crafted websockets PING after a script
12 calls r:wsupgrade() can cause a child process crash.
13 [Edward Lu <Chaosed0 gmail.com>]
14
15 *) mod_proxy: Don't put the worker in error state for 500 or 503 errors
16 returned by the backend unless failonstatus is configured to. PR 56925.
17 [Yann Ylavic]
18
19 *) core: Don't lowercase the argument to SetHandler if it begins with
20 "proxy:unix". PR 57968. [Eric Covener]
21
22 *) mod_ssl OCSP Stapling: Don't block initial handshakes while refreshing
23 the OCSP response for a different certificate. mod_ssl has an additional
24 global mutex, "ssl-stapling-refresh". PR 57131 (partial fix).
25 [Jeff Trawick]
26
27 *) mod_authz_dbm: Fix crashes when "dbm-file-group" is used and

31 of DB lookup entries independently of the selected DB engine. PR 46421.
32 [Steven whitson <steven.whitson gmail com>, Jan Kaluza, Yann Ylavic].
33
34 *) In alignment with RFC 7525, the default recommended SSLCipherSuite
35 and SSLProxyCipherSuite now exclude RC4 as well as MD5. Also, the
36 default recommended SSLProtocol and SSLProxyProtocol directives now
37 exclude SSLv3. Existing configurations must be adjusted by the
38 administrator. [William Rowe]
39
40 *) mod_ssl: Add support for extracting subjectAltName entries of type
41 rfc822Name and dNSName into SSL_{CLIENT,SERVER}_SAN_{Email,DNS}_n
42 environment variables. Also addresses PR 57207. [Kaspar Brand]

45 no If headers providing them on a resource we aren't modifying.
46 [Ben Reser]
47
48 *) mod_proxy_scgi: ProxySCGIInternalRedirect now allows an alternate
49 response header to be used by the application, for when the application
50 or framework is unable to return Location in the internal-redirect
51 form. [Jeff Trawick]
52
53 *) core: Cleanup the request soon/even if some output filter fails to
54 handle the EOR bucket. [Yann Ylavic]
55
56 *) mpm_event: Allow for timer events duplicates. [Jim Jagielski, Yann Ylavic]

59 readable server-status produced when using the "?auto" query string.
60 [Rainer Jung]
61
62 *) mod_status: Add more data to machine readable server-status produced
63 when using the "?auto" query string. [Rainer Jung]
64
65 *) mod_ssl: Check for the Entropy Gathering Daemon (EGD) availability at
66 configure time (RAND_egd), and complain if SSLRandomSeed requires using
67 it otherwise. [Bernard Spil <pil.oss gmail com>, Stefan Sperling,
68 Kaspar Brand]
69
70 *) mod_ssl: make sure to consistently output SSLCertificateChainFile
71 deprecation warnings, when encountered in a VirtualHost block.
72 [Falco Schwarz <hiding falco.me>]
73
74 *) mod_log_config: Add "%{UNIT}T" format to output request duration in

78 *) Allow FallbackResource to work when a directory is requested and
79 there is no autoindex nor DirectoryIndex.
80 [Jack <tjerk.meesters gmail.com>, Eric Covener]
81
82 *) mod_proxy_wstunnel: Bypass the handler while the connection is not
83 upgraded to WebSocket, so that other modules can possibly take over
84 the leading HTTP requests. [Yann Ylavic]
85
86 *) mod_http: Fix incorrect If-Match handling. PR 57358
87 [Kunihiko Sakamoto <ksakamoto google.com>]
88
89 *) mod_ssl: Add a warning if protocol given in SSLProtocol or SSLProxyProtocol
90 will override other parameters given in the same directive. This could be
91 a missing + or - prefix. PR 52820 [Christophe Jaillet]
92
93 *) core, modules: Avoid error response/document handling by the core if some
94 handler or input filter already did it while reading the request (causing
95 a double response body). [Yann Ylavic]
96
97 *) mod_proxy_ajp: Fix client connection errors handling and logged status
98 when it occurs. PR 56823. [Yann Ylavic]
99
100 *) mod_proxy: Use the correct server name for SNI in case the backend
101 SSL connection itself is established via a proxy server.
102 PR 57139 [Szabolcs Gyurko <szabolcs gyurko.org>]
103
104 *) mod_ssl: Fix possible crash when loading server certificate constraints.
105 PR 57694. [Paul Spangler <paul.spangler ni com>, Yann Ylavic]

107 *) build: Don't load both mod_cgi and mod_cgid in the default configuration
108 if they're both built. [olli hauer <ohauer gmx.de>]
109
110 *) mod_logio: Add LogIOTrackTTFB and %^FB logformat to log the time
111 taken to start writing response headers. [Eric Covener]

114 the use of ENGINE_CTRL_CHIL_SET_FORKCHECK.
115 [Stuart Henderson <sthen openbsd.org>]
116
117 *) mod_proxy_http: Use the "Connection: close" header for requests to
118 backends not recycling connections (disablereuse), including the default
119 reverse and forward proxies. [Yann Ylavic]
120
121 *) mod_proxy: Add ap_connection_reusable() for checking if a connection
122 is reusable as of this point in processing. [Jeff Trawick]
123
124 *) mod_proxy_wstunnel: Avoid an empty response by failing with 502 (Bad
125 Gateway) when no response is ever received from the backend.
126 [Jan Kaluza]
127
128 *) core_filters: Restore/disable TCP_NOPUSH option after non-blocking
129 sendfile. [Yann Ylavic]
130
131 *) mod_buffer: Forward flushed input data immediately and avoid (unlikely)
132 access to freed memory. [Yann Ylavic, Christophe Jaillet]

139 to avoid a crash when relocation occurs. PR 57177. [Yann Ylavic]
140
141 *) mod_dav: Avoid a potential integer underflow in the lock timeout value sent
142 back to a client. The answer to a LOCK request could be an extremly large
143 integer if the time needed to lock the resource was longer that the
144 requested timeout given in the LOCK request. In such a case, we now answer
145 "Second-0". PR55420
146 [Christophe Jaillet]
147
148 *) mod_cgid: Within the first minute of a server start or restart,
149 allow mod_cgid to retry connecting to its daemon process. Previously,
150 'No such file or directory: unable to connect to cgi daemon...' could
151 be logged without an actual retry. PR57685.
152 [Edward Lu <Chaosed0 gmail.com>]
153
154 *) mod_proxy: Use the original (non absolute) form of the request-line's URI
155 for requests embedded in CONNECT payloads used to connect SSL backends via
156 a ProxyRemote forward-proxy. PR 55892. [Hendrik Harms <hendrik.harms
157 gmail com>, William Rowe, Yann Ylavic]
158
159 *) http: Make ap_die() robust against any HTTP error code and not modify
160 response status (finally logged) when nothing is to be done. [Yann Ylavic]
161
162 *) mod_proxy_connect/wstunnel: If both client and backend sides get readable
163 at the same time, don't lose errors occuring while forwarding on the first
164 side when none occurs next on the other side, and abort. [Yann Ylavic]
165
166 *) mod_rewrite: Improve relative substitutions in per-directory/htaccess
167 context for directories found by mod_userdir and mod_alias. These no
168 longer require RewriteBase to be specified. [Eric Covener]
169
170 *) mod_proxy_http: Don't expect the backend to ack the "Connection: close" to
171 finally close those not meant to be kept alive by SetEnv proxy-nokeepalive
172 or force-proxy-request-1.0. [Yann Ylavic]
173
174 *) core: If explicitly configured, use the KeepaliveTimeout value of the
175 virtual host which handled the latest request on the connection, or by
176 default the one of the first virtual host bound to the same IP:port.
177 PR56226. [Yann Ylavic]
178
179 *) mod_lua: After a r:wsupgrade(), mod_lua was not properly

181 script. PR57524. [Edward Lu <Chaosed0 gmail.com>]
182
183 *) mod_ssl: Add the SSL_CLIENT_CERT_RFC4523_CEA variable, which provides
184 a combination of certificate serialNumber and issuer as defined by
185 CertificateExactMatch in RFC4523. [Graham Leggett]
186
187 *) core: Add expression support to ErrorDocument. Switch from a fixed
188 sized 664 byte array per merge to a hash table. [Graham Leggett]
189
190 *) ab: Add missing longest request (100%) to CSV export.
191 [Marcin Fabrykowski <bugzilla fabrykowski.pl>]
192
193 *) mod_macro: Clear macros before initialization to avoid use-after-free
194 on startup or restart when the module is linked statically. PR 57525
195 [apache.org tech.futurequest.net, Yann Ylavic]
196
197 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
198 and Redirect. [Graham Leggett]
199
200 *) mod_ssl: 'SSLProtocol ALL' was being ignored in virtual host context.
201 PR 57100. [Michael Kaufmann <apache-bugzilla michael-kaufmann.ch>,
202 Yann Ylavic]
203
204 *) mpm_event: Avoid access to the scoreboard from the connection while
205 it is suspended (waiting for events). [Eric Covener, Jeff Trawick]
206
207 *) mod_ssl: Fix renegotiation failures redirected to an ErrorDocument.
208 PR 57334. [Yann Ylavic].
209
210 *) mod_deflate: A misplaced check prevents limiting small bodies with the
211 new inflate limits. PR56872. [Edward Lu, Eric Covener, Yann Ylavic]
212
213 *) mod_proxy_ajp: Forward SSL protocol name (SSLv3, TLSv1.1 etc.) as a
214 request attribute to the backend. Recent Tomcat versions will extract
215 it and provide it as a servlet request attribute named
216 "org.apache.tomcat.util.net.secure_protocol_version". [Rainer Jung]
217
218 *) core: Optimize string concatenation in expression parser when evaluating
219 a string expression. [Rainer Jung]

225 *) mod_authn_dbd: Fix the error message logged in case of error while querying
226 the database. This is associated to AH01656 and AH01661. [Christophe Jaillet]
227

231 *) mod_ssl: Fix small memory leak during initialization when ECDH is used.
232 [Jan Kaluza]
233

250 *) SECURITY: CVE-2014-3583 (cve.mitre.org)
251 mod_proxy_fcgi: Fix a potential crash due to buffer over-read, with
252 response headers' size above 8K. [Yann Ylavic, Jeff Trawick]
253

260 used in multiple Require directives with different arguments.
261 PR57204 [Edward Lu <Chaosed0 gmail.com>]
262
263 *) SECURITY: CVE-2013-5704 (cve.mitre.org)
264 core: HTTP trailers could be used to replace HTTP headers
265 late during request processing, potentially undoing or
266 otherwise confusing modules that examined or modified
267 request headers earlier. Adds "MergeTrailers" directive to restore
268 legacy behavior. [Edward Lu, Yann Ylavic, Joe Orton, Eric Covener]
269
270 *) mod_ssl: New directive SSLSessionTickets (On|Off).
271 The directive controls the use of TLS session tickets (RFC 5077),
272 default value is "On" (unchanged behavior).
273 Session ticket creation uses a random key created during web
274 server startup and recreated during restarts. No other key
275 recreation mechanism is available currently. Therefore using session
276 tickets without restarting the web server with an appropriate frequency
277 (e.g. daily) compromises perfect forward secrecy. [Rainer Jung]
278
279 *) mod_proxy_fcgi: Provide some basic alternate options for specifying
280 how PATH_INFO is passed to FastCGI backends by adding significance to
281 the value of proxy-fcgi-pathinfo. PR 55329. [Eric Covener]

284 to opt-in to connection reuse and other Proxy options via explicitly
285 declared "proxy workers" (<Proxy unix:... enablereuse=on max=...)
286 [Eric Covener]
287
288 *) mod_proxy: Add "enablereuse" option as the inverse of "disablereuse".
289 [Eric Covener]
290
291 *) mod_proxy_fcgi: Enable opt-in to TCP connection reuse by explicitly
292 setting proxy option disablereuse=off. [Eric Covener] PR 57378.
293
294 *) event: Update the internal "connection id" when requests
295 move from thread to thread. Reuse can confuse modules like
296 mod_cgid. PR 57435. [Michael Thorpe <mike gistnet.com>]
297
298 *) mod_proxy_fcgi: Remove proxy:balancer:// prefix from SCRIPT_FILENAME
299 passed to fastcgi backends. [Eric Covener]
300
301 *) core: Configuration files with long lines and continuation characters
302 are not read properly. PR 55910. [Manuel Mausz <manuel-as mausz.at>]
303

306 statements. [Christophe Jaillet]
307
308 *) split-logfile: Fix perl error: 'Can't use string ("example.org:80")
309 as a symbol ref while "strict refs"'. PR 56329.
310 [Holger Mauermann <mauermann gmail.com>]
311
312 *) mod_proxy: Prevent ProxyPassReverse from doing a substitution when
313 the URL parameter interpolates to an empty string. PR 56603.
314 [<ajprout hotmail.com>]
315
316 *) core: Fix -D[efined] or <Define>[d] variables lifetime accross restarts.
317 PR 57328. [Armin Abfalterer <a.abfalterer gmail.com>, Yann Ylavic].
318
319 *) mod_proxy: Preserve original request headers even if they differ
320 from the ones to be forwarded to the backend. PR 45387.
321 [Yann Ylavic]
322
323 *) mod_ssl: dump SSL IO/state for the write side of the connection(s),
324 like reads (level TRACE4). [Yann Ylavic]
325
326 *) mod_proxy_fcgi: Ignore body data from backend for 304 responses. PR 57198.
327 [Jan Kaluza]
328
329 *) mod_ssl: Do not crash when looking up SSL related variables during
330 expression evaluation on non SSL connections. PR 57070 [Ruediger Pluem]
331
332 *) mod_proxy_ajp: Fix handling of the default port (8009) in the
333 ProxyPass and <Proxy> configurations. PR 57259. [Yann Ylavic]

348 PR 53435 [tadanori <tadanori2007 yahoo.com>, Sebastian Wiedenroth <wiedi frubar.net>]
349
350 *) mod_proxy_connect: Don't issue AH02447 on sockets hangups, let the read
351 determine whether it is a normal close or a real error. PR 57168. [Yann
352 Ylavic]

4182 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
4183 [Chris Darroch <chrisd pearsoncmg.com>]
4184
4185 *) mod_charset_lite: Remove Content-Length when output filter can
4186 invalidate it. Warn when input filter can invalidate it.
4187 [Jeff Trawick]
4188
4189 *) Authz: Add the new module mod_authn_core that will provide common
4190 authn directives such as 'AuthType', 'AuthName'. Move the directives
4191 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
4192 into mod_authn_core. [Brad Nicholes]
4193
4194 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
4195 into the new module mod_access_compat which can be loaded to provide
4196 support for these directives.
4197 [Brad Nicholes]
4198
4199 *) Authz: Move the 'Require' directive from the core module as well as
4200 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
4201 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
4202 logic into the authorization processing. [Brad Nicholes]
4203
4204 *) Authz: Add the new module mod_authz_core which acts as the
4205 authorization provider vector and contains common authz
4206 directives. [Brad Nicholes]
4207
4208 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
4209 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
4210
4211 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
4212 host-based access control provided by mod_authz_host and invoked
4213 through the 'Require' directive. [Brad Nicholes]
4214
4215 *) Authz: Convert all of the authz modules from hook based to
4216 provider based. [Brad Nicholes]
4217
4218 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
4219 seconds to cache a document.

4222 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
4223
4224 *) Fix typo in ProxyStatus syntax error message.
4225 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
4226
4227 *) Asynchronous write completion for the Event MPM. [Brian Pane]
4228
4229 *) Added an End-Of-Request bucket type. The logging of a request and
4230 the freeing of its pool are now done when the EOR bucket is destroyed.
4231 This has the effect of delaying the logging until right after the last
4232 of the response is sent; ap_core_output_filter() calls the access logger
4233 indirectly when it destroys the EOR bucket. [Brian Pane]
4234
4235 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
4236 and the format of statistical output has changed. [Colm MacCarthaigh]
4237
4238 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
4239
4240 *) Added new connection states for handler and write completion
4241 [Brian Pane]
4242
4243 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
4244 [Justin Erenkrantz]
4245
4246 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
4247 allowing string-valued client certificate attributes to be used for
4248 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
