34 core: HTTP trailers could be used to replace HTTP headers
35 late during request processing, potentially undoing or
36 otherwise confusing modules that examined or modified
37 request headers earlier. Adds "MergeTrailers" directive to restore
38 legacy behavior. [Edward Lu, Yann Ylavic, Joe Orton, Eric Covener]
39
40 *) mod_log_config: Allow three character log formats to be registered. For

68 limits the length and compression ratio of inflated request bodies to
69 avoid denial of service via highly compressed bodies. See directives
70 DeflateInflateLimitRequestBody, DeflateInflateRatioLimit,
71 and DeflateInflateRatioBurst. [Yann Ylavic, Eric Covener]
72
73 *) SECURITY: CVE-2014-0231 (cve.mitre.org)
74 mod_cgid: Fix a denial of service against CGI scripts that do
75 not consume stdin that could lead to lingering HTTPD child processes
76 filling up the scoreboard and eventually hanging the server. By
77 default, the client I/O timeout (Timeout directive) now applies to

2036
2037 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
2038 process as opposed to disabling caching completely. This allows to use
2039 the non-shared-memory cache as a workaround for the shared memory cache
2040 not being available during graceful restarts. PR 48958. [Stefan Fritsch]

2121 were not active during server startup but got enabled later during a
2122 graceful restart. [Stefan Fritsch]

2183 <Files> section. [Stefan Fritsch]

2197 authorization directives were mixed. [Stefan Fritsch]
2198
2199 *) mod_authn_socache: change directive name from AuthnCacheProvider
2200 to AuthnCacheProvideFor. The term "provider" is overloaded in
2201 this module, and we should avoid confusion between the provider
2202 of a backend (AuthnCacheSOCache) and the authn provider(s) for
2203 which this module provides cacheing (AuthnCacheProvideFor).
2204 [Nick Kew]
2205
2206 *) mod_proxy_http: Allocate the fake backend request from a child pool
2207 of the backend connection, instead of misusing the pool of the frontend
2208 request. Fixes a thread safety issue where buckets set aside in the
2209 backend connection leak into other threads, and then disappear when
2210 the frontend request is cleaned up, in turn causing corrupted buckets
2211 to make other threads spin. [Graham Leggett]
2212
2213 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
2214 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and

2238 the port over a wildcard (or omitted) port instead of favoring the one
2239 that came first in the configuration file. [Eric Covener]

3733
3734 *) ap_get_server_version() has been removed. Third-party modules must
3735 now use ap_get_server_banner() or ap_get_server_description().
3736 [Jeff Trawick]
3737
3738 *) All MPMs: Introduce a check_config phase between pre_config and
3739 open_logs, to allow modules to review interdependent configuration
3740 directive values and adjust them while messages can still be logged
3741 to the console. Handle relevant MPM directives during this phase
3742 and format messages for both the console and the error log, as
3743 appropriate. [Chris Darroch]
3744
3745 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
3746 to circumvent the symbolic link checks imposed by FollowSymLinks and
3747 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
3748
3749 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
3750 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
3751 The default is none as this is far greater debugging resolution than
3752 the typical administrator is prepared to untangle. [William Rowe]
3753
3754 *) mod_disk_cache: If possible, check if the size of an object to cache is
3755 within the configured boundaries before actually saving data.
3756 [Niklas Edmundsson <nikke acc.umu.se>]
3757
3758 *) Worker and event MPMs: Remove improper scoreboard updates which were
3759 performed in the event of a fork() failure. [Chris Darroch]
3760
3761 *) Add support for fcgi:// proxies to mod_rewrite.
3762 [Markus Schiegl <ms schiegl.com>]
3763
3764 *) Remove incorrect comments from scoreboard.h regarding conditional
3765 loading of worker_score structure with mod_status, and remove unused
3766 definitions relating to old life_status field.
3767 [Chris Darroch <chrisd pearsoncmg.com>]
3768
3769 *) Remove allocation of memory for unused array of lb_score pointers
3770 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
3771
3772 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
3773 [Garrett Rooney, Jim Jagielski, Paul Querna]
3774
3775 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
3776 [Chris Darroch <chrisd pearsoncmg.com>]
3777
3778 *) mod_charset_lite: Remove Content-Length when output filter can
3779 invalidate it. Warn when input filter can invalidate it.
3780 [Jeff Trawick]
3781
3782 *) Authz: Add the new module mod_authn_core that will provide common
3783 authn directives such as 'AuthType', 'AuthName'. Move the directives
3784 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
3785 into mod_authn_core. [Brad Nicholes]
3786
3787 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
3788 into the new module mod_access_compat which can be loaded to provide
3789 support for these directives.
3790 [Brad Nicholes]
3791
3792 *) Authz: Move the 'Require' directive from the core module as well as
3793 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
3794 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
3795 logic into the authorization processing. [Brad Nicholes]
3796
3797 *) Authz: Add the new module mod_authz_core which acts as the
3798 authorization provider vector and contains common authz
3799 directives. [Brad Nicholes]
3800
3801 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
3802 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
3803
3804 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
3805 host-based access control provided by mod_authz_host and invoked
3806 through the 'Require' directive. [Brad Nicholes]
3807
3808 *) Authz: Convert all of the authz modules from hook based to
3809 provider based. [Brad Nicholes]
3810
3811 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
3812 seconds to cache a document.
3813 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
3814
3815 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
3816
3817 *) Fix typo in ProxyStatus syntax error message.
3818 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
3819
3820 *) Asynchronous write completion for the Event MPM. [Brian Pane]
3821
3822 *) Added an End-Of-Request bucket type. The logging of a request and
3823 the freeing of its pool are now done when the EOR bucket is destroyed.
3824 This has the effect of delaying the logging until right after the last
3825 of the response is sent; ap_core_output_filter() calls the access logger
3826 indirectly when it destroys the EOR bucket. [Brian Pane]
3827
3828 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
3829 and the format of statistical output has changed. [Colm MacCarthaigh]
3830
3831 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
3832
3833 *) Added new connection states for handler and write completion
3834 [Brian Pane]
3835
3836 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
3837 [Justin Erenkrantz]
3838
3839 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
3840 allowing string-valued client certificate attributes to be used for
3841 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
3842 [Martin Kraemer, David Reid]
