244 The HTTP strict parsing changes added in 2.2.32 and 2.4.24 introduced a
245 bug in token list parsing, which allows ap_find_token() to search past
246 the end of its input string. By maliciously crafting a sequence of
247 request headers, an attacker may be able to cause a segmentation fault,
248 or to force ap_find_token() to return an incorrect value.
251 *) SECURITY: CVE-2017-7659 (cve.mitre.org)
252 A maliciously constructed HTTP/2 request could cause mod_http2 to
253 dereference a NULL pointer and crash the server process.

281 scheme/host/port matches the current virtual host, stop interpreting the
282 path component as a local path just because the first component of the

312 systems. [Eric Covener]
314 *) mod_http2: fail requests without ERROR log in case we need to read interim
315 responses and see only garbage. This can happen if proxied servers send

368 *) core: %{DOCUMENT_URI} used in nested SSI expressions should point to the
369 URI originally requsted by the user, not the nested documents URI. This

378 a "proxy:fcgi://" prefix in the SCRIPT_FILENAME environment variable by
379 default. Add ProxyFCGIBackendType to allow the type of backend to be

585 *) mod_dav: Fix a potential cause of unbounded memory usage or incorrect
586 behavior in a routine that sends <DAV:response>'s to the output filters.
589 *) mod_http2: new directive 'H2PushResource' to enable early pushes before
590 processing of the main request starts. Resources are announced to the
591 client in Link headers on a 103 early hint response.
592 All responses with status code <400 are inspected for Link header and
593 trigger pushes accordingly. 304 still does prevent pushes.
594 'H2PushResource' can mark resources as 'critical' which gives them higher
595 priority than the main resource. This leads to preferred scheduling for
596 processing and, when content is available, will send it first. 'critical'
597 is also recognized on Link headers. [Stefan Eissing]
599 *) mod_proxy_http2: uris in Link headers are now mapped back to a suitable
600 local url when available. Relative uris with an absolute path are mapped
601 as well. This makes reverse proxy mapping available for resources
602 announced in this header.
603 With 103 interim responses being forwarded to the main client connection,
604 this effectively allows early pushing of resources by a reverse proxied
605 backend server. [Stefan Eissing]

643 Requests headers are not delayed by this, since they are repeatable in
644 case of failure. This greatly increases robustness, especially with
645 busy server and/or low keepalive connections. [Stefan Eissing]

1002 *) mod_http2: number of worker threads allowed to a connection is adjusting
1003 dynamically. Starting with 4, the number is doubled when streams can be
1004 served without block on http/2 connection flow. The number is halfed, when
1005 the server has to wait on client flow control grants.
1006 This can happen with a maximum frequency of 5 times per second.
1007 When a connection occupies too many workers, repeatable requests
1008 (GET/HEAD/OPTIONS) are cancelled and placed back in the queue. Should that
1009 not suffice and a stream is busy longer than the server timeout, the
1010 connection will be aborted with error code ENHANCE_YOUR_CALM.
1011 This does *not* limit the number of streams a client may open, rather the

3981 *) mod_authn_socache: change directive name from AuthnCacheProvider
3982 to AuthnCacheProvideFor. The term "provider" is overloaded in
3983 this module, and we should avoid confusion between the provider
3984 of a backend (AuthnCacheSOCache) and the authn provider(s) for
3985 which this module provides cacheing (AuthnCacheProvideFor).
3988 *) mod_proxy_http: Allocate the fake backend request from a child pool
3989 of the backend connection, instead of misusing the pool of the frontend
3990 request. Fixes a thread safety issue where buckets set aside in the
3991 backend connection leak into other threads, and then disappear when
3992 the frontend request is cleaned up, in turn causing corrupted buckets
3993 to make other threads spin. [Graham Leggett]

4020 the port over a wildcard (or omitted) port instead of favoring the one

4118 ap_expr's public interface and provide hooks for modules to add variables

4178 running out of space when many small files are cached.
4181 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
4182 describes more accurately what the directive does. The old name
4183 still works but logs a warning. [Stefan Fritsch]
4185 *) mod_cache: Optionally serve stale data when a revalidation returns a

4217 *) mod_ssl: Add authz providers for use with mod_authz_core and its
4218 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
4219 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
4220 'ssl-require' (expressions with same syntax as SSLRequire).
4223 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
4224 bison instead of yacc. [Stefan Fritsch]
4226 *) mod_disk_cache: Change on-disk header file format to support the
4227 link of the device/inode of the data file to the matching header
4228 file, and to support the option of not writing a data file when
4229 the data file is empty. [Graham Leggett]
4231 *) core/mod_unique_id: Add generate_log_id hook to allow to use
4232 the ID generated by mod_unique_id as error log ID for requests.
4235 *) mod_cache: Make sure that we never allow a 304 Not Modified response
4236 that we asked for to leak to the client should the 304 response be
4237 uncacheable. PR45341 [Graham Leggett]
4239 *) mod_cache: Add the cache_status hook to register the final cache
4240 decision hit/miss/revalidate. Add optional support for an X-Cache
4241 and/or an X-Cache-Detail header to add the cache status to the
4242 response. PR48241 [Graham Leggett]
4244 *) mod_authz_host: Add 'local' provider that matches connections originating
4245 on the local host. PR 19938. [Stefan Fritsch]
4247 *) Event MPM: Fix crash accessing pollset on worker thread when child
4248 process is exiting. [Jeff Trawick]
4250 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
4251 pass the system library path (LD_LIBRARY_PATH or platform-specific
4252 variables) along with the system PATH, by default. Both should be
4253 overridden together as desired using PassEnv etc; see mod_env.
4256 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
4257 capture a stale backend response, perform If-Modified-Since requests
4258 against the backend, and serving from the cache all 304 responses.
4259 This restores pre-2.2.4 cache behavior. [William Rowe]
4261 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
4262 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
4263 the ambiguity of the symlink test "-ltest", introduce -h or -L as
4264 symlink test operators. [William Rowe]
4266 *) mod_cache: Give the cache provider the opportunity to choose to cache
4267 or not cache based on the buckets present in the brigade, such as the
4268 presence of a FILE bucket.
4271 *) mod_authz_core: Allow authz providers to check args while reading the
4272 config and allow to cache parsed args. Move 'all' and 'env' authz
4273 providers from mod_authz_host to mod_authz_core. Add 'method' authz
4274 provider depending on the HTTP method. [Stefan Fritsch]
4276 *) mod_include: Move the request_rec within mod_include to be
4277 exposed within include_ctx_t. [Graham Leggett]
4279 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
4280 variable being echoed or set to be decoded and then encoded as separate
4281 steps. PR47686 [Graham Leggett]
4283 *) mod_cache: Add a discrete commit_entity() provider function within the
4284 mod_cache provider interface which is called to indicate to the
4285 provider that caching is complete, giving the provider the opportunity
4286 to commit temporary files permanently to the cache in an atomic
4287 fashion. Replace the inconsistent use of error cleanups with a formal
4288 set of pool cleanups attached to a subpool, which is destroyed on error.
4291 *) mod_cache: Change the signature of the store_body() provider function
4292 within the mod_cache provider interface to support an "in" brigade
4293 and an "out" brigade instead of just a single input brigade. This
4294 gives a cache provider the option to consume only part of the brigade
4295 passed to it, rather than the whole brigade as was required before.
4296 This fixes an out of memory and a request timeout condition that would
4297 occur when the original document was a large file. Introduce
4298 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
4299 the amount of data to attempt to cache at a time. [Graham Leggett]
4301 *) core: Add ErrorLogFormat to allow configuring error log format, including
4302 additional information that is logged once per connection or request. Add
4303 error log IDs for connections and request to allow correlating error log
4304 lines and the corresponding access log entry. [Stefan Fritsch]
4306 *) core: Disable sendfile by default. [Stefan Fritsch]
4308 *) mod_cache: Check the request to determine whether we are allowed
4309 to return cached content at all, and respect a "Cache-Control:
4310 no-cache" header from a client. Previously, "no-cache" would
4311 behave like "max-age=0". [Graham Leggett]
4313 *) mod_cache: Use a proper filter context to hold filter data instead
4314 of misusing the per-request configuration. Fixes a segfault on trunk

5457 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
5458 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
5459 provide the unusual legacy lookup. [William Rowe]

5464 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
5465 parameters to the environment. Improve portability to
5466 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
5468 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
5469 to authorize an authenticated user via a "require ldap-group X" directive
5470 where the user is not in group X, but is in a subgroup contained in X.

5483 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
5486 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
5487 cleanups registered in modules' child_init hooks are performed.
5490 *) Fix issue which could cause error messages to be written to access logs
5491 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
5493 *) The LockFile directive, which specifies the location of
5494 the accept() mutex lockfile, is deprecated. Instead, the
5495 AcceptMutex directive now takes an optional lockfile
5496 location parameter, ala SSLMutex. [Jim Jagielski]
5498 *) mod_authn_dbd: Export any additional columns queried in the SQL select
5499 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
5500 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
5502 *) mod_dbd: Key the storage of prepared statements on the hex string
5503 value of server_rec, rather than the server name, as the server name
5504 may change (eg when the server name is set) at any time, causing
5505 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
5507 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
5509 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
5510 the first bucket from the brigade, finds it not to be a FILE
5511 bucket and barfs. The fix is to pass a bucket rather than a brigade.

5514 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
5516 *) ap_get_server_version() has been removed. Third-party modules must
5517 now use ap_get_server_banner() or ap_get_server_description().
5520 *) All MPMs: Introduce a check_config phase between pre_config and
5521 open_logs, to allow modules to review interdependent configuration
5522 directive values and adjust them while messages can still be logged
5523 to the console. Handle relevant MPM directives during this phase
5524 and format messages for both the console and the error log, as
5525 appropriate. [Chris Darroch]
5527 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
5528 to circumvent the symbolic link checks imposed by FollowSymLinks and
5529 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
5531 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
5532 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
5533 The default is none as this is far greater debugging resolution than

5560 *) mod_charset_lite: Remove Content-Length when output filter can
5561 invalidate it. Warn when input filter can invalidate it.
5564 *) Authz: Add the new module mod_authn_core that will provide common
5565 authn directives such as 'AuthType', 'AuthName'. Move the directives
5566 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
5567 into mod_authn_core. [Brad Nicholes]
5569 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
5570 into the new module mod_access_compat which can be loaded to provide
5571 support for these directives.
5574 *) Authz: Move the 'Require' directive from the core module as well as
5575 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
5576 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
5577 logic into the authorization processing. [Brad Nicholes]
5579 *) Authz: Add the new module mod_authz_core which acts as the
5580 authorization provider vector and contains common authz
5581 directives. [Brad Nicholes]
5583 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
5584 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
5586 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
5587 host-based access control provided by mod_authz_host and invoked
5588 through the 'Require' directive. [Brad Nicholes]
5590 *) Authz: Convert all of the authz modules from hook based to

5602 *) Asynchronous write completion for the Event MPM. [Brian Pane]
5604 *) Added an End-Of-Request bucket type. The logging of a request and
5605 the freeing of its pool are now done when the EOR bucket is destroyed.
5606 This has the effect of delaying the logging until right after the last
5607 of the response is sent; ap_core_output_filter() calls the access logger
5608 indirectly when it destroys the EOR bucket. [Brian Pane]
5610 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
5611 and the format of statistical output has changed. [Colm MacCarthaigh]
5613 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
5615 *) Added new connection states for handler and write completion
5618 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
5621 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
5622 allowing string-valued client certificate attributes to be used for
5623 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
