3 Changes with Apache 2.3.9
5 *) mod_include: Move the request_rec within mod_include to be
6 exposed within include_ctx_t. [Graham Leggett]
8 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
9 variable being echoed or set to be decoded and then encoded as separate
10 steps. PR47686 [Graham Leggett]
12 *) mod_cache: Add a discrete commit_entity() provider function within the
13 mod_cache provider interface which is called to indicate to the
14 provider that caching is complete, giving the provider the opportunity
15 to commit temporary files permanently to the cache in an atomic
16 fashion. Replace the inconsistent use of error cleanups with a formal
17 set of pool cleanups attached to a subpool, which is destroyed on error.
20 *) mod_cache: Change the signature of the store_body() provider function
21 within the mod_cache provider interface to support an "in" brigade
22 and an "out" brigade instead of just a single input brigade. This
23 gives a cache provider the option to consume only part of the brigade
24 passed to it, rather than the whole brigade as was required before.
25 This fixes an out of memory and a request timeout condition that would
26 occur when the original document was a large file. Introduce
27 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
28 the amount of data to attempt to cache at a time. [Graham Leggett]
30 *) core: Add ErrorLogFormat to allow configuring error log format, including
31 additional information that is logged once per connection or request. Add
32 error log IDs for connections and request to allow correlating error log
33 lines and the corresponding access log entry. [Stefan Fritsch]
35 *) core: Disable sendfile by default. [Stefan Fritsch]
37 *) mod_cache: Check the request to determine whether we are allowed
38 to return cached content at all, and respect a "Cache-Control:
39 no-cache" header from a client. Previously, "no-cache" would
40 behave like "max-age=0". [Graham Leggett]
42 *) mod_cache: Use a proper filter context to hold filter data instead
43 of misusing the per-request configuration. Fixes a segfault on trunk
44 when the normal handler is used. [Graham Leggett]
46 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
47 it is too long. PR 49388. [Stefan Fritsch]
49 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
50 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
51 directives for the same address:port, or NameVirtualHost
52 directives with no matching VirtualHosts, or multiple ip-based
53 VirtualHost sections for the same address:port. These were
54 previously accepted with a warning, but the behavior was
55 undefined. [Dan Poirier]
57 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
58 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
60 *) core: DirectoryMatch can now match on the end of line character ($),
61 and sub-directories of matched directories are no longer implicitly
62 matched. PR49809 [Eric Covener]
64 Changes with Apache 2.3.8
66 *) suexec: Support large log files. PR 45856. [Stefan Fritsch]
68 *) core: Abort with sensible error message if no or more than one MPM is
69 loaded. [Stefan Fritsch]
71 *) mod_proxy: Rename erroronstatus to failonstatus.

80 mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
81 segment. PR: 49246 [Mark Drayton, Jeff Trawick]
83 *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
86 *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
89 *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
90 via leveraging 100-Continue as the initial "request".
93 *) core/mod_authz_core: Introduce new access_checker_ex hook that enables
94 mod_authz_core to bypass authentication if access should be allowed by
95 IP address/env var/... [Stefan Fritsch]
97 *) core: Introduce note_auth_failure hook to allow modules to add support
98 for additional auth types. This makes ap_note_auth_failure() work with
99 mod_auth_digest again. PR 48807. [Stefan Fritsch]
101 *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
103 *) mod_authn_cache: new module [Nick Kew]
105 *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
107 *) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
109 *) mod_rewrite: Allow to set environment variables without explicitly
110 giving a value. [Rainer Jung]
112 *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
114 *) mod_include: recognise "text/html; parameters" as text/html
115 PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
117 *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
120 *) Core: Extra robustness: don't try authz and segfault if authn
121 fails to set r->user. Log bug and return 500 instead.
124 *) HTTP protocol filter: fix handling of longer chunk extensions
125 PR 49474 [<tee.bee gmx.de>]
127 *) Update SSL cipher suite and add example for SSLHonorCipherOrder.
128 [Lars Eilebrecht, Rainer Jung]
130 *) move AddOutputFilterByType from core to mod_filter. This should
131 fix nasty side-effects that happen when content_type is set
132 more than once in processing a request, and make it fully
133 compatible with dynamic and proxied contents. [Nick Kew]
135 *) mod_log_config: Implement logging for sub second timestamps and
136 request end time. [Rainer Jung]
138 Changes with Apache 2.3.6
140 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
141 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
142 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
143 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
144 and offer unsafe legacy renegotiation with clients which do not yet
145 support the new secure renegotiation protocol, RFC 5746.
146 [Joe Orton, and with thanks to the OpenSSL Team]
148 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
149 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
150 by rejecting any client-initiated renegotiations. Forcibly disable
151 keepalive for the connection if there is any buffered data readable. Any
152 configuration which requires renegotiation for per-directory/location
153 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
154 [Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
156 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
157 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
158 when request headers indicate a request body is incoming; not a case of
159 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
161 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
162 mod_isapi: Do not unload an isapi .dll module until the request
163 processing is completed, avoiding orphaned callback pointers.
164 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
166 *) core: Filter init functions are now run strictly once per request
167 before handler invocation. The init functions are no longer run
168 for connection filters. PR 49328. [Joe Orton]
170 *) core: Adjust the output filter chain correctly in an internal
171 redirect from a subrequest, preserving filters from the main
172 request as necessary. PR 17629. [Joe Orton]
174 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
175 Response if they so choose to do so. Previously an attempt to cache a 206
176 was arbitrarily allowed if the response contained an Expires or
177 Cache-Control header, and arbitrarily denied if both headers were missing.
180 *) core: Add microsecond timestamp fractions, process id and thread id
181 to the error log. [Rainer Jung]
183 *) configure: The "most" module set gets build by default. [Rainer Jung]

191 with APR 2 and for VPATH builds with included APR.
194 *) mod_session_crypto: API compatibility with APR 2 crypto and
195 APR Util 1.x crypto. [Rainer Jung]
197 *) ab: Fix memory leak with -v2 and SSL. PR 49383.
198 [Pavel Kankovsky <peak argo troja mff cuni cz>]
200 *) core: Add per-module and per-directory loglevel configuration.
201 Add some more trace logging.
202 mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels.
203 mod_ssl: Replace LogLevelDebugDump with trace log levels.
204 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
206 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
209 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
210 title page only) when any mod_ldap directives were used in VirtualHost
211 context. [Eric Covener]
213 *) mod_disk_cache: Decline the opportunity to cache if the response is
214 a 206 Partial Content. This stops a reverse proxied partial response
215 from becoming cached, and then being served in subsequent responses.
218 *) mod_deflate: avoid the risk of forwarding data before headers are set.

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

226 can use the credentials from the authentication phase
227 (AuthLDAPSearchAsUSer,AuthLDAPCompareAsUser).

342 *) mod_proxy_http: Make sure that when an ErrorDocument is served
343 from a reverse proxied URL, that the subrequest respects the status
344 of the original request. This brings the behaviour of proxy_handler

1140 to newly created sub requests; as these are later on used
1141 as true requests with an internal redirect. This allows for
1142 mod_cache et.al. to trap the results of the redirect.
1143 [Dirk-Willem van Gulik, Ruediger Pluem]
1145 *) mod_ldap: Add support (taking advantage of the new APR capability)
1146 for ldap rebind callback while chasing referrals. This allows direct
1147 searches on LDAP servers (in particular MS Active Directory 2003+)
1148 using referrals without the use of the global catalog.

1151 *) ApacheMonitor.exe: Introduce --kill argument for use by the
1152 installer. This will permit the installation tool to remove
1153 all running instances before attempting to remove the .exe.
1156 *) mod_ssl: Add support for OCSP validation of client certificates.
1157 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
1159 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
1161 *) core: Add the option to keep aside a request body up to a certain
1162 size that would otherwise be discarded, to be consumed by filters
1163 such as mod_include. When enabled for a directory, POST requests
1164 to shtml files can be passed through to embedded scripts as POST
1165 requests, rather being downgraded to GET requests. [Graham Leggett]
1167 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
1169 *) scoreboard: Correctly declare ap_time_process_request.
1170 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
1172 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
1173 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
1174 provide the unusual legacy lookup. [William Rowe]
1176 *) mpm winnt: fix null pointer dereference
1177 PR 42572 [Davi Arnaut]
1179 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
1180 parameters to the environment. Improve portability to
1181 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
1183 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
1184 to authorize an authenticated user via a "require ldap-group X" directive
1185 where the user is not in group X, but is in a subgroup contained in X.
1186 PR 42891 [Paul J. Reder]
1188 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
1190 *) apxs: Enhance -q flag to print all known variables and their values
1191 when invoked without variable name(s).

1197 *) beos MPM: Create pmain pool and run modules' child_init hooks when
1198 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
1201 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
1202 cleanups registered in modules' child_init hooks are performed.
1205 *) Fix issue which could cause error messages to be written to access logs
1206 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
1208 *) The LockFile directive, which specifies the location of
1209 the accept() mutex lockfile, is deprecated. Instead, the
1210 AcceptMutex directive now takes an optional lockfile
1211 location parameter, ala SSLMutex. [Jim Jagielski]
1213 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1214 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1215 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1217 *) mod_dbd: Key the storage of prepared statements on the hex string
1218 value of server_rec, rather than the server name, as the server name
1219 may change (eg when the server name is set) at any time, causing
1220 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1222 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1224 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1225 the first bucket from the brigade, finds it not to be a FILE
1226 bucket and barfs. The fix is to pass a bucket rather than a brigade.

1229 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1231 *) ap_get_server_version() has been removed. Third-party modules must
1232 now use ap_get_server_banner() or ap_get_server_description().
1235 *) All MPMs: Introduce a check_config phase between pre_config and
1236 open_logs, to allow modules to review interdependent configuration
1237 directive values and adjust them while messages can still be logged
1238 to the console. Handle relevant MPM directives during this phase
1239 and format messages for both the console and the error log, as
1240 appropriate. [Chris Darroch]
1242 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1243 to circumvent the symbolic link checks imposed by FollowSymLinks and
1244 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1246 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1247 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1248 The default is none as this is far greater debugging resolution than
1249 the typical administrator is prepared to untangle. [William Rowe]
1251 *) mod_disk_cache: If possible, check if the size of an object to cache is
1252 within the configured boundaries before actually saving data.

1255 *) Worker and event MPMs: Remove improper scoreboard updates which were
1256 performed in the event of a fork() failure. [Chris Darroch]

1266 *) Remove allocation of memory for unused array of lb_score pointers

1275 *) mod_charset_lite: Remove Content-Length when output filter can
1276 invalidate it. Warn when input filter can invalidate it.
1279 *) Authz: Add the new module mod_authn_core that will provide common
1280 authn directives such as 'AuthType', 'AuthName'. Move the directives
1281 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1282 into mod_authn_core. [Brad Nicholes]
1284 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1285 into the new module mod_access_compat which can be loaded to provide
1286 support for these directives.
1289 *) Authz: Move the 'Require' directive from the core module as well as
1290 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1291 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1292 logic into the authorization processing. [Brad Nicholes]
1294 *) Authz: Add the new module mod_authz_core which acts as the
1295 authorization provider vector and contains common authz
1296 directives. [Brad Nicholes]
1298 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1299 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1301 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1302 host-based access control provided by mod_authz_host and invoked
1303 through the 'Require' directive. [Brad Nicholes]
1305 *) Authz: Convert all of the authz modules from hook based to
1306 provider based. [Brad Nicholes]
1308 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1309 seconds to cache a document.
1310 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
1312 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
1314 *) Fix typo in ProxyStatus syntax error message.
1315 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1317 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1319 *) Added an End-Of-Request bucket type. The logging of a request and
1320 the freeing of its pool are now done when the EOR bucket is destroyed.
1321 This has the effect of delaying the logging until right after the last
1322 of the response is sent; ap_core_output_filter() calls the access logger
1323 indirectly when it destroys the EOR bucket. [Brian Pane]
1325 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1326 and the format of statistical output has changed. [Colm MacCarthaigh]
1328 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1330 *) Added new connection states for handler and write completion
1333 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1336 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1337 allowing string-valued client certificate attributes to be used for
1338 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
