3 Changes with Apache 2.3.9
5 *) mod_ssl: Add authz providers for use with mod_authz_core and its
6 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
7 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
8 'ssl-require' (expressions with same syntax as SSLRequire).
11 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
12 bison instead of yacc. [Stefan Fritsch]
14 *) mod_disk_cache: Change on-disk header file format to support the
15 link of the device/inode of the data file to the matching header
16 file, and to support the option of not writing a data file when
17 the data file is empty. [Graham Leggett]
19 *) core/mod_unique_id: Add generate_log_id hook to allow to use
20 the ID generated by mod_unique_id as error log ID for requests.
22 *) mod_cache: Make sure that we never allow a 304 Not Modified response
23 that we asked for to leak to the client should the 304 response be
24 uncacheable. PR45341 [Graham Leggett]
26 *) mod_cache: Add the cache_status hook to register the final cache
27 decision hit/miss/revalidate. Add optional support for an X-Cache
28 and/or an X-Cache-Detail header to add the cache status to the
29 response. PR48241 [Graham Leggett]
31 *) mod_authz_host: Add 'local' provider that matches connections originating
32 on the local host. PR 19938. [Stefan Fritsch]
34 *) Event MPM: Fix crash accessing pollset on worker thread when child
35 process is exiting. [Jeff Trawick]
37 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
38 pass the system library path (LD_LIBRARY_PATH or platform-specific
39 variables) along with the system PATH, by default. Both should be
40 overridden together as desired using PassEnv etc; see mod_env.
43 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
44 capture a stale backend response, perform If-Modified-Since requests
45 against the backend, and serving from the cache all 304 responses.
46 This restores pre-2.2.4 cache behavior. [William Rowe]
48 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
49 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
50 the ambiguity of the symlink test "-ltest", introduce -h or -L as
51 symlink test operators. [William Rowe]
53 *) mod_cache: Give the cache provider the opportunity to choose to cache
54 or not cache based on the buckets present in the brigade, such as the
55 presence of a FILE bucket.
58 *) mod_authz_core: Allow authz providers to check args while reading the
59 config and allow to cache parsed args. Move 'all' and 'env' authz
60 providers from mod_authz_host to mod_authz_core. Add 'method' authz
61 provider depending on the HTTP method. [Stefan Fritsch]
63 *) mod_include: Move the request_rec within mod_include to be
64 exposed within include_ctx_t. [Graham Leggett]
66 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
67 variable being echoed or set to be decoded and then encoded as separate
68 steps. PR47686 [Graham Leggett]
70 *) mod_cache: Add a discrete commit_entity() provider function within the
71 mod_cache provider interface which is called to indicate to the
72 provider that caching is complete, giving the provider the opportunity
73 to commit temporary files permanently to the cache in an atomic
74 fashion. Replace the inconsistent use of error cleanups with a formal
75 set of pool cleanups attached to a subpool, which is destroyed on error.
78 *) mod_cache: Change the signature of the store_body() provider function
79 within the mod_cache provider interface to support an "in" brigade
80 and an "out" brigade instead of just a single input brigade. This
81 gives a cache provider the option to consume only part of the brigade
82 passed to it, rather than the whole brigade as was required before.
83 This fixes an out of memory and a request timeout condition that would
84 occur when the original document was a large file. Introduce
85 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
86 the amount of data to attempt to cache at a time. [Graham Leggett]
88 *) core: Add ErrorLogFormat to allow configuring error log format, including
89 additional information that is logged once per connection or request. Add
90 error log IDs for connections and request to allow correlating error log
91 lines and the corresponding access log entry. [Stefan Fritsch]
93 *) core: Disable sendfile by default. [Stefan Fritsch]
95 *) mod_cache: Check the request to determine whether we are allowed
96 to return cached content at all, and respect a "Cache-Control:
97 no-cache" header from a client. Previously, "no-cache" would
98 behave like "max-age=0". [Graham Leggett]
100 *) mod_cache: Use a proper filter context to hold filter data instead
101 of misusing the per-request configuration. Fixes a segfault on trunk
102 when the normal handler is used. [Graham Leggett]
104 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
105 it is too long. PR 49388. [Stefan Fritsch]
107 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
108 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
109 directives for the same address:port, or NameVirtualHost
110 directives with no matching VirtualHosts, or multiple ip-based
111 VirtualHost sections for the same address:port. These were
112 previously accepted with a warning, but the behavior was
113 undefined. [Dan Poirier]
115 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
116 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
118 *) core: DirectoryMatch can now match on the end of line character ($),
119 and sub-directories of matched directories are no longer implicitly
120 matched. PR49809 [Eric Covener]
122 *) Regexps: introduce new higher-level regexp utility including parsing
123 and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory
126 Changes with Apache 2.3.8
128 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
130 *) core: Abort with sensible error message if no or more than one MPM is
131 loaded. [Stefan Fritsch]
133 *) mod_proxy: Rename erroronstatus to failonstatus.
134 [Daniel Ruggeri <DRuggeri primary.net>]
136 *) mod_dav_fs: Fix broken "creationdate" property.
137 Regression in version 2.3.7. [Rainer Jung]
139 Changes with Apache 2.3.7
141 *) SECURITY: CVE-2010-1452 (cve.mitre.org)
142 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
143 segment. PR: 49246 [Mark Drayton, Jeff Trawick]
145 *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
148 *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
151 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
152 via leveraging 100-Continue as the initial "request".
155 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
156 mod_authz_core to bypass authentication if access should be allowed by
157 IP address/env var/... [Stefan Fritsch]
159 *) core: Introduce note_auth_failure hook to allow modules to add support
160 for additional auth types. This makes ap_note_auth_failure() work with
161 mod_auth_digest again. PR 48807. [Stefan Fritsch]
163 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
165 *) mod_authn_cache: new module [Nick Kew]
167 *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
169 *) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
171 *) mod_rewrite: Allow to set environment variables without explicitly
172 giving a value. [Rainer Jung]
174 *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
176 *) mod_include: recognise "text/html; parameters" as text/html
177 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
179 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
182 *) Core: Extra robustness: don't try authz and segfault if authn
183 fails to set r->user. Log bug and return 500 instead.
186 *) HTTP protocol filter: fix handling of longer chunk extensions
187 PR 49474 [<tee.bee gmx.de>]
189 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
190 [Lars Eilebrecht, Rainer Jung]
192 *) move AddOutputFilterByType from core to mod_filter. This should
193 fix nasty side-effects that happen when content_type is set
194 more than once in processing a request, and make it fully
195 compatible with dynamic and proxied contents. [Nick Kew]
197 *) mod_log_config: Implement logging for sub second timestamps and
198 request end time. [Rainer Jung]
200 Changes with Apache 2.3.6
202 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
203 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
204 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
205 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
206 and offer unsafe legacy renegotiation with clients which do not yet
207 support the new secure renegotiation protocol, RFC 5746.
208 [Joe Orton, and with thanks to the OpenSSL Team]
210 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
211 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
212 by rejecting any client-initiated renegotiations. Forcibly disable
213 keepalive for the connection if there is any buffered data readable. Any
214 configuration which requires renegotiation for per-directory/location
215 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
216 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
218 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
219 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
220 when request headers indicate a request body is incoming; not a case of
221 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
223 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
224 mod_isapi: Do not unload an isapi .dll module until the request
225 processing is completed, avoiding orphaned callback pointers.
226 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
228 *) core: Filter init functions are now run strictly once per request
229 before handler invocation. The init functions are no longer run
230 for connection filters. PR 49328. [Joe Orton]
232 *) core: Adjust the output filter chain correctly in an internal
233 redirect from a subrequest, preserving filters from the main
234 request as necessary. PR 17629. [Joe Orton]
236 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
237 Response if they so choose to do so. Previously an attempt to cache a 206
238 was arbitrarily allowed if the response contained an Expires or
239 Cache-Control header, and arbitrarily denied if both headers were missing.
242 *) core: Add microsecond timestamp fractions, process id and thread id
243 to the error log. [Rainer Jung]
245 *) configure: The "most" module set gets build by default. [Rainer Jung]

257 APR Util 1.x crypto. [Rainer Jung]
259 *) ab: Fix memory leak with -v2 and SSL. PR 49383.
260 [Pavel Kankovsky <peak argo troja mff cuni cz>]

263 Add some more trace logging.
264 mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels.
265 mod_ssl: Replace LogLevelDebugDump with trace log levels.
266 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
268 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
271 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
272 title page only) when any mod_ldap directives were used in VirtualHost
273 context. [Eric Covener]
275 *) mod_disk_cache: Decline the opportunity to cache if the response is
276 a 206 Partial Content. This stops a reverse proxied partial response
277 from becoming cached, and then being served in subsequent responses.
280 *) mod_deflate: avoid the risk of forwarding data before headers are set.

284 top-level group doesn't have any direct non-group members
285 of attributes in AuthLDAPGroupAttribute. [Eric Covener]

399 *) Introduce mod_reflector, a handler capable of reflecting POSTed
400 request bodies back within the response through the output filter

1126 new module called mod_request, reducing the size of the core.
1129 *) mod_dbd: Handle integer configuration directive parameters with a
1132 *) Change the directives within the mod_session* modules to be valid
1133 both inside and outside the location/directory sections, as
1134 suggested by wrowe. [Graham Leggett]
1136 *) mod_auth_form: Add a module capable of allowing end users to log
1137 in using an HTML form, storing the credentials within mod_session.
1140 *) Add a function to the http filters that is able to parse an HTML
1141 form request with the type of application/x-www-form-urlencoded.
1144 *) mod_session_crypto: Initialise SSL in the post config hook.
1145 [Ruediger Pluem, Graham Leggett]
1147 *) mod_session_dbd: Add a session implementation capable of storing
1148 session information in a SQL database via the dbd interface. Useful
1149 for sites where session privacy is important. [Graham Leggett]
1151 *) mod_session_crypto: Add a session encoding implementation capable
1152 of encrypting and decrypting sessions wherever they may be stored.
1153 Introduces a level of privacy when sessions are stored on the
1154 browser. [Graham Leggett]
1156 *) mod_session_cookie: Add a session implementation capable of storing
1157 session information within cookies on the browser. Useful for high
1158 volume sites where server bound sessions are too resource intensive.
1161 *) mod_session: Add a generic session interface to unify the different
1162 attempts at saving persistent sessions across requests.
1165 *) core, authn/z: Avoid calling access control hooks for internal requests
1166 with configurations which match those of initial request. Revert to
1167 original behaviour (call access control hooks for internal requests
1168 with URIs different from initial request) if any access control hooks or
1169 providers are not registered as permitting this optimization.
1170 Introduce wrappers for access control hook and provider registration
1171 which can accept additional mode and flag data. [Chris Darroch]
1173 *) Introduced ap_expr API for expression evaluation.
1174 This is adapted from mod_include, which is the first module
1178 *) mod_authz_dbd: When redirecting after successful login/logout per
1179 AuthzDBDRedirectQuery, do not report authorization failure, and use
1180 first row returned by database query instead of last row.

1207 *) mod_ldap: Add support (taking advantage of the new APR capability)
1208 for ldap rebind callback while chasing referrals. This allows direct
1209 searches on LDAP servers (in particular MS Active Directory 2003+)
1210 using referrals without the use of the global catalog.

1280 value of server_rec, rather than the server name, as the server name
1281 may change (eg when the server name is set) at any time, causing
1282 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1284 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1286 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1287 the first bucket from the brigade, finds it not to be a FILE

1342 authn directives such as 'AuthType', 'AuthName'. Move the directives
1343 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1344 into mod_authn_core. [Brad Nicholes]
1346 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1347 into the new module mod_access_compat which can be loaded to provide
1348 support for these directives.
1351 *) Authz: Move the 'Require' directive from the core module as well as
1352 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1353 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1354 logic into the authorization processing. [Brad Nicholes]
1356 *) Authz: Add the new module mod_authz_core which acts as the
1357 authorization provider vector and contains common authz
1358 directives. [Brad Nicholes]

1379 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1381 *) Added an End-Of-Request bucket type. The logging of a request and
1382 the freeing of its pool are now done when the EOR bucket is destroyed.
1383 This has the effect of delaying the logging until right after the last
1384 of the response is sent; ap_core_output_filter() calls the access logger
1385 indirectly when it destroys the EOR bucket. [Brian Pane]
