3 Changes with Apache 2.3.9
5 *) mod_authz_host: Add 'local' provider that matches connections originating
6 on the local host. PR 19938. [Stefan Fritsch]
8 *) Event MPM: Fix crash accessing pollset on worker thread when child
9 process is exiting. [Jeff Trawick]
11 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
12 pass the system library path (LD_LIBRARY_PATH or platform-specific
13 variables) along with the system PATH, by default. Both should be
14 overridden together as desired using PassEnv etc; see mod_env.
17 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
18 capture a stale backend response, perform If-Modified-Since requests
19 against the backend, and serving from the cache all 304 responses.
20 This restores pre-2.2.4 cache behavior. [William Rowe]
22 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
23 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
24 the ambiguity of the symlink test "-ltest", introduce -h or -L as
25 symlink test operators. [William Rowe]
27 *) mod_cache: Give the cache provider the opportunity to choose to cache
28 or not cache based on the buckets present in the brigade, such as the
29 presence of a FILE bucket.
32 *) mod_authz_core: Allow authz providers to check args while reading the
33 config and allow to cache parsed args. Move 'all' and 'env' authz
34 providers from mod_authz_host to mod_authz_core. Add 'method' authz
35 provider depending on the HTTP method. [Stefan Fritsch]
37 *) mod_include: Move the request_rec within mod_include to be
38 exposed within include_ctx_t. [Graham Leggett]
40 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
41 variable being echoed or set to be decoded and then encoded as separate
42 steps. PR47686 [Graham Leggett]
44 *) mod_cache: Add a discrete commit_entity() provider function within the
45 mod_cache provider interface which is called to indicate to the
46 provider that caching is complete, giving the provider the opportunity
47 to commit temporary files permanently to the cache in an atomic
48 fashion. Replace the inconsistent use of error cleanups with a formal
49 set of pool cleanups attached to a subpool, which is destroyed on error.
52 *) mod_cache: Change the signature of the store_body() provider function
53 within the mod_cache provider interface to support an "in" brigade
54 and an "out" brigade instead of just a single input brigade. This
55 gives a cache provider the option to consume only part of the brigade
56 passed to it, rather than the whole brigade as was required before.
57 This fixes an out of memory and a request timeout condition that would
58 occur when the original document was a large file. Introduce
59 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
60 the amount of data to attempt to cache at a time. [Graham Leggett]
62 *) core: Add ErrorLogFormat to allow configuring error log format, including
63 additional information that is logged once per connection or request. Add
64 error log IDs for connections and request to allow correlating error log
65 lines and the corresponding access log entry. [Stefan Fritsch]
67 *) core: Disable sendfile by default. [Stefan Fritsch]
69 *) mod_cache: Check the request to determine whether we are allowed
70 to return cached content at all, and respect a "Cache-Control:
71 no-cache" header from a client. Previously, "no-cache" would
72 behave like "max-age=0". [Graham Leggett]
74 *) mod_cache: Use a proper filter context to hold filter data instead
75 of misusing the per-request configuration. Fixes a segfault on trunk
76 when the normal handler is used. [Graham Leggett]
78 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
79 it is too long. PR 49388. [Stefan Fritsch]
81 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
82 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
83 directives for the same address:port, or NameVirtualHost
84 directives with no matching VirtualHosts, or multiple ip-based
85 VirtualHost sections for the same address:port. These were
86 previously accepted with a warning, but the behavior was
87 undefined. [Dan Poirier]
89 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
90 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
92 *) core: DirectoryMatch can now match on the end of line character ($),
93 and sub-directories of matched directories are no longer implicitly
94 matched. PR49809 [Eric Covener]
96 *) Regexps: introduce new higher-level regexp utility including parsing
97 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
100 Changes with Apache 2.3.8
102 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
104 *) core: Abort with sensible error message if no or more than one MPM is
105 loaded. [Stefan Fritsch]
107 *) mod_proxy: Rename erroronstatus to failonstatus.
108 [Daniel Ruggeri <DRuggeri primary.net>]
110 *) mod_dav_fs: Fix broken "creationdate" property.
111 Regression in version 2.3.7. [Rainer Jung]
113 Changes with Apache 2.3.7
115 *) SECURITY: CVE-2010-1452 (cve.mitre.org)
116 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
117 segment. PR: 49246 [Mark Drayton, Jeff Trawick]
119 *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
122 *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
125 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
126 via leveraging 100-Continue as the initial "request".
129 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
130 mod_authz_core to bypass authentication if access should be allowed by
131 IP address/env var/... [Stefan Fritsch]
133 *) core: Introduce note_auth_failure hook to allow modules to add support
134 for additional auth types. This makes ap_note_auth_failure() work with
135 mod_auth_digest again. PR 48807. [Stefan Fritsch]
137 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
139 *) mod_authn_cache: new module [Nick Kew]
141 *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
143 *) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
145 *) mod_rewrite: Allow to set environment variables without explicitly
146 giving a value. [Rainer Jung]
148 *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
150 *) mod_include: recognise "text/html; parameters" as text/html
151 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
153 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
156 *) Core: Extra robustness: don't try authz and segfault if authn
157 fails to set r->user. Log bug and return 500 instead.
160 *) HTTP protocol filter: fix handling of longer chunk extensions
161 PR 49474 [<tee.bee gmx.de>]
163 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
164 [Lars Eilebrecht, Rainer Jung]
166 *) move AddOutputFilterByType from core to mod_filter. This should
167 fix nasty side-effects that happen when content_type is set
168 more than once in processing a request, and make it fully
169 compatible with dynamic and proxied contents. [Nick Kew]
171 *) mod_log_config: Implement logging for sub second timestamps and
172 request end time. [Rainer Jung]
174 Changes with Apache 2.3.6
176 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
177 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
178 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
179 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
180 and offer unsafe legacy renegotiation with clients which do not yet
181 support the new secure renegotiation protocol, RFC 5746.
182 [Joe Orton, and with thanks to the OpenSSL Team]
184 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
185 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
186 by rejecting any client-initiated renegotiations. Forcibly disable
187 keepalive for the connection if there is any buffered data readable. Any
188 configuration which requires renegotiation for per-directory/location
189 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
190 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
192 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
193 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
194 when request headers indicate a request body is incoming; not a case of
195 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
197 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
198 mod_isapi: Do not unload an isapi .dll module until the request
199 processing is completed, avoiding orphaned callback pointers.
200 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
202 *) core: Filter init functions are now run strictly once per request
203 before handler invocation. The init functions are no longer run
204 for connection filters. PR 49328. [Joe Orton]
206 *) core: Adjust the output filter chain correctly in an internal
207 redirect from a subrequest, preserving filters from the main
208 request as necessary. PR 17629. [Joe Orton]
210 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
211 Response if they so choose to do so. Previously an attempt to cache a 206
212 was arbitrarily allowed if the response contained an Expires or
213 Cache-Control header, and arbitrarily denied if both headers were missing.
216 *) core: Add microsecond timestamp fractions, process id and thread id
217 to the error log. [Rainer Jung]
219 *) configure: The "most" module set gets build by default. [Rainer Jung]
221 *) configure: Building dynamic modules (DSO) by default. [Rainer Jung]

231 APR Util 1.x crypto. [Rainer Jung]
233 *) ab: Fix memory leak with -v2 and SSL. PR 49383.
234 [Pavel Kankovsky <peak argo troja mff cuni cz>]
236 *) core: Add per-module and per-directory loglevel configuration.
237 Add some more trace logging.
238 mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels.

240 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
242 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
245 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
246 title page only) when any mod_ldap directives were used in VirtualHost
247 context. [Eric Covener]
249 *) mod_disk_cache: Decline the opportunity to cache if the response is
250 a 206 Partial Content. This stops a reverse proxied partial response
251 from becoming cached, and then being served in subsequent responses.
254 *) mod_deflate: avoid the risk of forwarding data before headers are set.
255 PR 49369 [Matthew Steele <mdsteele google.com>]
257 *) mod_authnz_ldap: Ensure nested groups are checked when the
258 top-level group doesn't have any direct non-group members
259 of attributes in AuthLDAPGroupAttribute. [Eric Covener]
261 *) mod_authnz_ldap: Search or Comparison during authorization phase
262 can use the credentials from the authentication phase
263 (AuthLDAPSearchAsUSer,AuthLDAPCompareAsUser).
264 PR 48340 [Domenico Rotiroti, Eric Covener]

267 to use the HTTP username/pass instead of an anonymous or hard-coded
268 LDAP id (AuthLDAPInitialBindAsUser, AuthLDAPInitialBindPattern).

366 httpd's writing of a pid file) so that it becomes possible to run
367 more than one instance of htcacheclean on the same machine.
370 *) Log command line on startup, so there's a record of command line
371 arguments like -f. PR 48752. [Dan Poirier]
373 *) Introduce mod_reflector, a handler capable of reflecting POSTed
374 request bodies back within the response through the output filter
375 stack. Can be used to turn an output filter into a web service.
378 *) mod_proxy_http: Make sure that when an ErrorDocument is served
379 from a reverse proxied URL, that the subrequest respects the status
380 of the original request. This brings the behaviour of proxy_handler
381 in line with default_handler. PR 47106. [Graham Leggett]

1136 attempts at saving persistent sessions across requests.
1139 *) core, authn/z: Avoid calling access control hooks for internal requests
1140 with configurations which match those of initial request. Revert to
1141 original behaviour (call access control hooks for internal requests
1142 with URIs different from initial request) if any access control hooks or
1143 providers are not registered as permitting this optimization.
1144 Introduce wrappers for access control hook and provider registration
1145 which can accept additional mode and flag data. [Chris Darroch]
1147 *) Introduced ap_expr API for expression evaluation.
1148 This is adapted from mod_include, which is the first module
1152 *) mod_authz_dbd: When redirecting after successful login/logout per
1153 AuthzDBDRedirectQuery, do not report authorization failure, and use
1154 first row returned by database query instead of last row.
1157 *) mod_ldap: Correctly return all requested attribute values
1158 when some attributes have a null value.

1167 *) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
1168 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
1169 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
1171 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these

1173 third party module authors. PR 42431 [Dirk-Willem van Gulik].
1175 *) mod_dir, mod_negotiation: pass the output filter information
1176 to newly created sub requests; as these are later on used
1177 as true requests with an internal redirect. This allows for
1178 mod_cache et.al. to trap the results of the redirect.
1179 [Dirk-Willem van Gulik, Ruediger Pluem]
1181 *) mod_ldap: Add support (taking advantage of the new APR capability)
1182 for ldap rebind callback while chasing referrals. This allows direct
1183 searches on LDAP servers (in particular MS Active Directory 2003+)
1184 using referrals without the use of the global catalog.

1195 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
1197 *) core: Add the option to keep aside a request body up to a certain
1198 size that would otherwise be discarded, to be consumed by filters
1199 such as mod_include. When enabled for a directory, POST requests
1200 to shtml files can be passed through to embedded scripts as POST

1244 *) The LockFile directive, which specifies the location of
1245 the accept() mutex lockfile, is deprecated. Instead, the

1247 location parameter, ala SSLMutex. [Jim Jagielski]
1249 *) mod_authn_dbd: Export any additional columns queried in the SQL select

1253 *) mod_dbd: Key the storage of prepared statements on the hex string
1254 value of server_rec, rather than the server name, as the server name
1255 may change (eg when the server name is set) at any time, causing
1256 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1258 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1260 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1261 the first bucket from the brigade, finds it not to be a FILE

1271 *) All MPMs: Introduce a check_config phase between pre_config and
1272 open_logs, to allow modules to review interdependent configuration
1273 directive values and adjust them while messages can still be logged
1274 to the console. Handle relevant MPM directives during this phase

1315 *) Authz: Add the new module mod_authn_core that will provide common
1316 authn directives such as 'AuthType', 'AuthName'. Move the directives
1317 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1318 into mod_authn_core. [Brad Nicholes]
1320 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1321 into the new module mod_access_compat which can be loaded to provide
1322 support for these directives.
1325 *) Authz: Move the 'Require' directive from the core module as well as
1326 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1327 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1328 logic into the authorization processing. [Brad Nicholes]
1330 *) Authz: Add the new module mod_authz_core which acts as the
1331 authorization provider vector and contains common authz
1332 directives. [Brad Nicholes]
1334 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1335 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1337 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1338 host-based access control provided by mod_authz_host and invoked
1339 through the 'Require' directive. [Brad Nicholes]
1341 *) Authz: Convert all of the authz modules from hook based to

1351 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1353 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1355 *) Added an End-Of-Request bucket type. The logging of a request and
1356 the freeing of its pool are now done when the EOR bucket is destroyed.
1357 This has the effect of delaying the logging until right after the last
1358 of the response is sent; ap_core_output_filter() calls the access logger
1359 indirectly when it destroys the EOR bucket. [Brian Pane]
1361 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1362 and the format of statistical output has changed. [Colm MacCarthaigh]
1364 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1366 *) Added new connection states for handler and write completion
1369 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1372 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1373 allowing string-valued client certificate attributes to be used for
1374 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
