3 Changes with Apache 2.3.10
6 Changes with Apache 2.3.9
8 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
9 Fix a denial of service attack against mod_reqtimeout.
12 *) mod_include: Add the onerror attribute to the include element,
13 allowing an URL to be specified to include on error. [Graham
16 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
17 consistent with the naming of other modules. [Graham Leggett]
19 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
20 expression. [Stefan Fritsch]
22 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
25 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
26 binary (Suexec Off), or force startup failure if suEXEC is required
27 but not supported (Suexec On). Change SuexecUserGroup to fail
28 startup instead of just printing a warning if suEXEC is disabled.
31 *) core: Add Error directive for aborting startup or htaccess processing
32 with a specified error message. [Jeff Trawick]
34 *) mod_rewrite: Fix the RewriteEngine directive to work within a
35 location. Previously, once RewriteEngine was switched on globally,
36 it was impossible to switch off. [Graham Leggett]
38 *) core, mod_include, mod_ssl: Move the expression parser derived from
39 mod_include back into mod_include. Replace ap_expr with a parser
40 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
41 ap_expr's public interface and provide hooks for modules to add variables
42 and functions. [Stefan Fritsch]
44 *) core: Do the hook sorting earlier so that the hooks are properly sorted
45 for the pre_config hook and during parsing the config. [Stefan Fritsch]
47 *) core: In the absence of any AllowOverride directives, the default is now
48 "None" instead of "All". PR49823 [Eric Covener]
50 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
51 <Directory> or <Files>. PR47765 [Eric Covener]
53 *) prefork/worker/event MPMS: default value (when no directive is present)
54 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
55 to match default configuration and manual. PR47782 [Eric Covener]
57 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
58 when the child process is starting to exit. PR50220. [Eric Covener]
60 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
61 contexts that don't have any mod_autoindex directives. PR47766.
64 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
65 of rewrite processing when a per-directory substitution occurs.
68 *) mod_ssl: Make sure to always log an error if loading of CA certificates
69 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
71 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
72 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
74 *) mod_dav: Send 400 error if malformed Content-Range header is received for
75 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
77 *) mod_proxy: Release the backend connection as soon as EOS is detected,
78 so the backend isn't forced to wait for the client to eventually
79 acknowledge the data. [Graham Leggett]
81 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
82 per-directory, and chosen during the location walk. Make ProxyPass
83 work correctly from within a LocationMatch. [Graham Leggett]
85 *) core: Fix segfault if per-module LogLevel is on virtual host
86 scope. PR 50117. [Stefan Fritsch]
88 *) mod_proxy: Move the ProxyErrorOverride directive to have per
89 directory scope. [Graham Leggett]
91 *) mod_allowmethods: New module to deny certain HTTP methods without
92 interfering with authentication/authorization. [Paul Querna,
93 Igor Galić, Stefan Fritsch]
95 *) mod_ssl: Log certificate information and improve error message if client
96 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
99 *) htcacheclean: Teach htcacheclean to limit cache size by number of
100 inodes in addition to size of files. Prevents a cache disk from
101 running out of space when many small files are cached.
104 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
105 describes more accurately what the directive does. The old name
106 still works but logs a warning. [Stefan Fritsch]
108 *) mod_cache: Optionally serve stale data when a revalidation returns a
109 5xx response, controlled by the CacheStaleOnError directive.
112 *) htcacheclean: Allow the listing of valid URLs within the cache, with
113 the option to list entry metadata such as sizes and times. [Graham
116 *) mod_cache: correctly parse quoted strings in cache headers.
119 *) mod_cache: Allow control over the base URL of reverse proxied requests
120 using the CacheKeyBaseURL directive, so that the cache key can be
121 calculated from the endpoint URL instead of the server URL. [Graham
124 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
125 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
126 CacheMinExpire and CacheMaxExpire can be set per directory/location.
129 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
130 CacheReadTime can be set per directory/location. [Graham Leggett]
132 *) core: Speed up config parsing if using a very large number of config
133 files. PR 50002 [andrew cloudaccess net]
135 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
137 *) htcacheclean: Allow the option to round up file sizes to a given
138 block size, improving the accuracy of disk usage. [Graham Leggett]
140 *) mod_ssl: Add authz providers for use with mod_authz_core and its
141 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
142 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
143 'ssl-require' (expressions with same syntax as SSLRequire).
146 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
147 bison instead of yacc. [Stefan Fritsch]
149 *) mod_disk_cache: Change on-disk header file format to support the
150 link of the device/inode of the data file to the matching header
151 file, and to support the option of not writing a data file when
152 the data file is empty. [Graham Leggett]
154 *) core/mod_unique_id: Add generate_log_id hook to allow to use
155 the ID generated by mod_unique_id as error log ID for requests.
158 *) mod_cache: Make sure that we never allow a 304 Not Modified response
159 that we asked for to leak to the client should the 304 response be
160 uncacheable. PR45341 [Graham Leggett]
162 *) mod_cache: Add the cache_status hook to register the final cache
163 decision hit/miss/revalidate. Add optional support for an X-Cache
164 and/or an X-Cache-Detail header to add the cache status to the
165 response. PR48241 [Graham Leggett]
167 *) mod_authz_host: Add 'local' provider that matches connections originating
168 on the local host. PR 19938. [Stefan Fritsch]
170 *) Event MPM: Fix crash accessing pollset on worker thread when child
171 process is exiting. [Jeff Trawick]
173 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
174 pass the system library path (LD_LIBRARY_PATH or platform-specific
175 variables) along with the system PATH, by default. Both should be
176 overridden together as desired using PassEnv etc; see mod_env.
179 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
180 capture a stale backend response, perform If-Modified-Since requests
181 against the backend, and serving from the cache all 304 responses.
182 This restores pre-2.2.4 cache behavior. [William Rowe]
184 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
185 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
186 the ambiguity of the symlink test "-ltest", introduce -h or -L as
187 symlink test operators. [William Rowe]
189 *) mod_cache: Give the cache provider the opportunity to choose to cache
190 or not cache based on the buckets present in the brigade, such as the
191 presence of a FILE bucket.
194 *) mod_authz_core: Allow authz providers to check args while reading the
195 config and allow to cache parsed args. Move 'all' and 'env' authz
196 providers from mod_authz_host to mod_authz_core. Add 'method' authz
197 provider depending on the HTTP method. [Stefan Fritsch]
199 *) mod_include: Move the request_rec within mod_include to be
200 exposed within include_ctx_t. [Graham Leggett]
202 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
203 variable being echoed or set to be decoded and then encoded as separate
204 steps. PR47686 [Graham Leggett]
206 *) mod_cache: Add a discrete commit_entity() provider function within the
207 mod_cache provider interface which is called to indicate to the
208 provider that caching is complete, giving the provider the opportunity
209 to commit temporary files permanently to the cache in an atomic
210 fashion. Replace the inconsistent use of error cleanups with a formal
211 set of pool cleanups attached to a subpool, which is destroyed on error.
214 *) mod_cache: Change the signature of the store_body() provider function
215 within the mod_cache provider interface to support an "in" brigade
216 and an "out" brigade instead of just a single input brigade. This
217 gives a cache provider the option to consume only part of the brigade
218 passed to it, rather than the whole brigade as was required before.
219 This fixes an out of memory and a request timeout condition that would
220 occur when the original document was a large file. Introduce
221 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
222 the amount of data to attempt to cache at a time. [Graham Leggett]
224 *) core: Add ErrorLogFormat to allow configuring error log format, including
225 additional information that is logged once per connection or request. Add
226 error log IDs for connections and request to allow correlating error log
227 lines and the corresponding access log entry. [Stefan Fritsch]
229 *) core: Disable sendfile by default. [Stefan Fritsch]
231 *) mod_cache: Check the request to determine whether we are allowed
232 to return cached content at all, and respect a "Cache-Control:
233 no-cache" header from a client. Previously, "no-cache" would
234 behave like "max-age=0". [Graham Leggett]
236 *) mod_cache: Use a proper filter context to hold filter data instead
237 of misusing the per-request configuration. Fixes a segfault on trunk
238 when the normal handler is used. [Graham Leggett]
240 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
241 it is too long. PR 49388. [Stefan Fritsch]
243 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
244 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
245 directives for the same address:port, or NameVirtualHost
246 directives with no matching VirtualHosts, or multiple ip-based
247 VirtualHost sections for the same address:port. These were
248 previously accepted with a warning, but the behavior was
249 undefined. [Dan Poirier]
251 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
252 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
254 *) core: DirectoryMatch can now match on the end of line character ($),
255 and sub-directories of matched directories are no longer implicitly
256 matched. PR49809 [Eric Covener]
258 *) Regexps: introduce new higher-level regexp utility including parsing
259 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
262 *) Proxy: support setting source address. PR 29404
263 [Multiple contributors iterating through bugzilla,
264 Aron Ujvari <xanco nikhok.hu>, Aleksey Midenkov <asm uezku.kemsu.ru>,
265 <dan listening-station.net; trunk version Nick Kew]
267 *) HTTP protocol: return 400 not 503 if we have to abort due to malformed
268 chunked encoding. [Nick Kew]
270 Changes with Apache 2.3.8
272 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
274 *) core: Abort with sensible error message if no or more than one MPM is
275 loaded. [Stefan Fritsch]
277 *) mod_proxy: Rename erroronstatus to failonstatus.
278 [Daniel Ruggeri <DRuggeri primary.net>]
280 *) mod_dav_fs: Fix broken "creationdate" property.
281 Regression in version 2.3.7. [Rainer Jung]
283 Changes with Apache 2.3.7
285 *) SECURITY: CVE-2010-1452 (cve.mitre.org)
286 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
287 segment. PR: 49246 [Mark Drayton, Jeff Trawick]

295 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
296 via leveraging 100-Continue as the initial "request".
299 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
300 mod_authz_core to bypass authentication if access should be allowed by
301 IP address/env var/... [Stefan Fritsch]
303 *) core: Introduce note_auth_failure hook to allow modules to add support
304 for additional auth types. This makes ap_note_auth_failure() work with
305 mod_auth_digest again. PR 48807. [Stefan Fritsch]
307 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]

321 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
323 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
326 *) Core: Extra robustness: don't try authz and segfault if authn
327 fails to set r->user. Log bug and return 500 instead.

333 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
334 [Lars Eilebrecht, Rainer Jung]
336 *) move AddOutputFilterByType from core to mod_filter. This should
337 fix nasty side-effects that happen when content_type is set
338 more than once in processing a request, and make it fully
339 compatible with dynamic and proxied contents. [Nick Kew]
341 *) mod_log_config: Implement logging for sub second timestamps and
342 request end time. [Rainer Jung]
344 Changes with Apache 2.3.6
346 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
347 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
348 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
349 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
350 and offer unsafe legacy renegotiation with clients which do not yet
351 support the new secure renegotiation protocol, RFC 5746.
352 [Joe Orton, and with thanks to the OpenSSL Team]
354 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
355 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
356 by rejecting any client-initiated renegotiations. Forcibly disable
357 keepalive for the connection if there is any buffered data readable. Any
358 configuration which requires renegotiation for per-directory/location
359 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
360 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
362 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
363 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
364 when request headers indicate a request body is incoming; not a case of
365 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
367 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
368 mod_isapi: Do not unload an isapi .dll module until the request
369 processing is completed, avoiding orphaned callback pointers.
370 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
372 *) core: Filter init functions are now run strictly once per request
373 before handler invocation. The init functions are no longer run
374 for connection filters. PR 49328. [Joe Orton]
376 *) core: Adjust the output filter chain correctly in an internal
377 redirect from a subrequest, preserving filters from the main
378 request as necessary. PR 17629. [Joe Orton]
380 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
381 Response if they so choose to do so. Previously an attempt to cache a 206
382 was arbitrarily allowed if the response contained an Expires or
383 Cache-Control header, and arbitrarily denied if both headers were missing.
386 *) core: Add microsecond timestamp fractions, process id and thread id
387 to the error log. [Rainer Jung]
389 *) configure: The "most" module set gets build by default. [Rainer Jung]
391 *) configure: Building dynamic modules (DSO) by default. [Rainer Jung]

396 *) mod_session_crypto: Fix configure problem when building
397 with APR 2 and for VPATH builds with included APR.
400 *) mod_session_crypto: API compatibility with APR 2 crypto and
401 APR Util 1.x crypto. [Rainer Jung]
403 *) ab: Fix memory leak with -v2 and SSL. PR 49383.
404 [Pavel Kankovsky <peak argo troja mff cuni cz>]

407 Add some more trace logging.
408 mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels.

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

1145 server is online. [Paul Querna]
1147 *) mod_buffer: Honour the flush bucket and flush the buffer in the
1148 input filter. Make sure that metadata buckets are written to
1149 the buffer, not to the final brigade. [Graham Leggett]
1151 *) mod_buffer: Optimise the buffering of heap buckets when the heap
1152 buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
1155 *) mod_buffer: Optional support for buffering of the input and output
1156 filter stacks. Can collapse many small buckets into fewer larger
1157 buckets, and prevents excessively small chunks being sent over
1158 the wire. [Graham Leggett]

1239 subrequests to support message bodies. Make sure that safety
1240 checks within the core and within the proxy are not triggered
1241 when kept_body is present. This makes it possible to embed
1242 proxied POST requests within mod_include. [Graham Leggett]

1245 up before reading the login form. Make sure the kept body filter
1246 is correctly inserted to ensure the body can be read a second
1247 time safely should the authn be successful. [Graham Leggett,

1265 cache modules consistent with ease. This API change bumps
1266 up the minor MM by one [Dirk-Willem van Gulik].
1268 *) Move the KeptBodySize directive, kept_body filters and the
1269 ap_parse_request_body function out of the http module and into a
1270 new module called mod_request, reducing the size of the core.
1273 *) mod_dbd: Handle integer configuration directive parameters with a

1301 session information within cookies on the browser. Useful for high
1302 volume sites where server bound sessions are too resource intensive.
1305 *) mod_session: Add a generic session interface to unify the different
1306 attempts at saving persistent sessions across requests.
1309 *) core, authn/z: Avoid calling access control hooks for internal requests
1310 with configurations which match those of initial request. Revert to
1311 original behaviour (call access control hooks for internal requests
1312 with URIs different from initial request) if any access control hooks or
1313 providers are not registered as permitting this optimization.
