3 Changes with Apache 2.3.9
5 *) core: Disable sendfile by default. [Stefan Fritsch]
7 *) mod_cache: Check the request to determine whether we are allowed
8 to return cached content at all, and respect a "Cache-Control:
9 no-cache" header from a client. Previously, "no-cache" would
10 behave like "max-age=0". [Graham Leggett]
12 *) mod_cache: Use a proper filter context to hold filter data instead
13 of misusing the per-request configuration. Fixes a segfault on trunk
14 when the normal handler is used. [Graham Leggett]

17 it is too long. PR 49388. [Stefan Fritsch]

20 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
21 directives for the same address:port, or NameVirtualHost
22 directives with no matching VirtualHosts, or multiple ip-based
23 VirtualHost sections for the same address:port. These were
24 previously accepted with a warning, but the behavior was
25 undefined. [Dan Poirier]

106 request end time. [Rainer Jung]
108 Changes with Apache 2.3.6
110 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
111 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
112 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
113 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
114 and offer unsafe legacy renegotiation with clients which do not yet
115 support the new secure renegotiation protocol, RFC 5746.
116 [Joe Orton, and with thanks to the OpenSSL Team]
118 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
119 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
120 by rejecting any client-initiated renegotiations. Forcibly disable
121 keepalive for the connection if there is any buffered data readable. Any
122 configuration which requires renegotiation for per-directory/location
123 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.

136 *) core: Filter init functions are now run strictly once per request
137 before handler invocation. The init functions are no longer run

140 *) core: Adjust the output filter chain correctly in an internal
141 redirect from a subrequest, preserving filters from the main
142 request as necessary. PR 17629. [Joe Orton]
144 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
145 Response if they so choose to do so. Previously an attempt to cache a 206
146 was arbitrarily allowed if the response contained an Expires or
147 Cache-Control header, and arbitrarily denied if both headers were missing.
150 *) core: Add microsecond timestamp fractions, process id and thread id
151 to the error log. [Rainer Jung]

179 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
180 title page only) when any mod_ldap directives were used in VirtualHost
181 context. [Eric Covener]
183 *) mod_disk_cache: Decline the opportunity to cache if the response is
184 a 206 Partial Content. This stops a reverse proxied partial response
185 from becoming cached, and then being served in subsequent responses.

1140 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
1142 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
1143 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
1144 provide the unusual legacy lookup. [William Rowe]
1146 *) mpm winnt: fix null pointer dereference
1147 PR 42572 [Davi Arnaut]
1149 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
1150 parameters to the environment. Improve portability to
1151 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
1153 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
1154 to authorize an authenticated user via a "require ldap-group X" directive
1155 where the user is not in group X, but is in a subgroup contained in X.
1156 PR 42891 [Paul J. Reder]
1158 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
1160 *) apxs: Enhance -q flag to print all known variables and their values
1161 when invoked without variable name(s).

1167 *) beos MPM: Create pmain pool and run modules' child_init hooks when
1168 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
1171 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
1172 cleanups registered in modules' child_init hooks are performed.
1175 *) Fix issue which could cause error messages to be written to access logs
1176 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
1178 *) The LockFile directive, which specifies the location of
1179 the accept() mutex lockfile, is deprecated. Instead, the
1180 AcceptMutex directive now takes an optional lockfile
1181 location parameter, ala SSLMutex. [Jim Jagielski]
1183 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1184 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1185 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1187 *) mod_dbd: Key the storage of prepared statements on the hex string
1188 value of server_rec, rather than the server name, as the server name
1189 may change (eg when the server name is set) at any time, causing
1190 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1192 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1194 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1195 the first bucket from the brigade, finds it not to be a FILE
1196 bucket and barfs. The fix is to pass a bucket rather than a brigade.

1199 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1201 *) ap_get_server_version() has been removed. Third-party modules must
1202 now use ap_get_server_banner() or ap_get_server_description().
1205 *) All MPMs: Introduce a check_config phase between pre_config and
1206 open_logs, to allow modules to review interdependent configuration
1207 directive values and adjust them while messages can still be logged
1208 to the console. Handle relevant MPM directives during this phase
1209 and format messages for both the console and the error log, as
1210 appropriate. [Chris Darroch]
1212 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1213 to circumvent the symbolic link checks imposed by FollowSymLinks and
1214 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1216 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1217 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1218 The default is none as this is far greater debugging resolution than
1219 the typical administrator is prepared to untangle. [William Rowe]
1221 *) mod_disk_cache: If possible, check if the size of an object to cache is
1222 within the configured boundaries before actually saving data.

1245 *) mod_charset_lite: Remove Content-Length when output filter can
1246 invalidate it. Warn when input filter can invalidate it.
1249 *) Authz: Add the new module mod_authn_core that will provide common
1250 authn directives such as 'AuthType', 'AuthName'. Move the directives
1251 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1252 into mod_authn_core. [Brad Nicholes]
1254 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1255 into the new module mod_access_compat which can be loaded to provide
1256 support for these directives.
1259 *) Authz: Move the 'Require' directive from the core module as well as
1260 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1261 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1262 logic into the authorization processing. [Brad Nicholes]
1264 *) Authz: Add the new module mod_authz_core which acts as the
1265 authorization provider vector and contains common authz
1266 directives. [Brad Nicholes]
1268 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1269 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1271 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1272 host-based access control provided by mod_authz_host and invoked
1273 through the 'Require' directive. [Brad Nicholes]
1275 *) Authz: Convert all of the authz modules from hook based to
1276 provider based. [Brad Nicholes]
1278 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1279 seconds to cache a document.

1285 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1287 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1289 *) Added an End-Of-Request bucket type. The logging of a request and
1290 the freeing of its pool are now done when the EOR bucket is destroyed.
1291 This has the effect of delaying the logging until right after the last
1292 of the response is sent; ap_core_output_filter() calls the access logger
1293 indirectly when it destroys the EOR bucket. [Brian Pane]
1295 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1296 and the format of statistical output has changed. [Colm MacCarthaigh]
1298 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1300 *) Added new connection states for handler and write completion
1303 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1306 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1307 allowing string-valued client certificate attributes to be used for
1308 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
