3 Changes with Apache 2.4.26
5 *) mod_rewrite: When a substitution is a fully qualified URL, and the
6 scheme/host/port matches the current virtual host, stop interpreting the
7 path component as a local path just because the first component of the
8 path exists in the filesystem. Adds RewriteOption "LegacyPrefixDocRoot"
9 to revert to previous behavior. PR60009.
10 [Hank Ibell <hwibell gmail.com>]
12 *) core: ap_parse_form_data() URL-decoding doesn't work on EBCDIC
13 platforms. PR61124. [Hank Ibell <hwibell gmail.com>]
15 *) ab: enable option processing for setting a custom HTTP method also for
16 non-SSL builds. [Rainer Jung]
18 *) core: EBCDIC fixes for interim responses with additional headers.
21 *) Evaluate nested If/ElseIf/Else configuration blocks.
22 [Luca Toscano, Jacob Champion]
24 *) mod_rewrite: Add 'BNP' (backreferences-no-plus) flag to RewriteRule to
25 allow spaces in backreferences to be encoded as %20 instead of '+'.
28 *) mod_rewrite: Add the possibility to limit the escaping to specific
29 characters in backreferences by listing them in the B flag.
32 *) mod_substitute: Fix spurious AH01328 (Line too long) errors on EBCDIC
33 systems. [Eric Covener]
35 *) mod_http2: fail requests without ERROR log in case we need to read interim
36 responses and see only garbage. This can happen if proxied servers send
37 data where none should be, e.g. a body for a HEAD request. [Stefan Eissing]
39 *) mod_proxy_http2: adding support for Reverse Proxy Request headers.
42 *) mod_http2: fixed possible deadlock that could occur when connections were
43 terminated early with ongoing streams. Fixed possible hanger with timeout
44 on race when connection considers itself idle. [Stefan Eissing]
46 *) mod_http2: MaxKeepAliveRequests now limits the number of times a
47 slave connection gets reused. [Stefan Eissing]
49 *) mod_brotli: Add a new module for dynamic Brotli (RFC 7932) compression.
52 *) mod_proxy_http2: Fixed bug in re-attempting proxy requests after
53 connection error. Reliability of reconnect handling improved.
56 *) mod_http2: better performance, eliminated need for nested locks and
57 thread privates. Moving request setups from the main connection to the
58 worker threads. Increase number of spare connections kept.
61 *) mod_http2: input buffering and dynamic flow windows for increased
62 throughput. Requires nghttp2 >= v1.5.0 features. Announced at startup
63 in mod_http2 INFO log as feature 'DWINS'. [Stefan Eissing]
65 *) mod_http2: h2 workers with improved scalability for better scheduling
66 performance. There are H2MaxWorkers threads created at start and the
67 number is kept constant for now. [Stefan Eissing]
69 *) mod_http2: obsoleted option H2SessionExtraFiles, will be ignored and
70 just log a warning. [Stefan Eissing]
72 *) mod_autoindex: Add IndexOptions UseOldDateFormat to allow the date
73 format from 2.2 in the Last Modified column. PR60846.
74 [Hank Ibell <hwibell gmail.com>]
76 *) core: Add %{REMOTE_PORT} to the expression parser. PR59938
77 [Hank Ibell <hwibell gmail.com>]
79 *) mod_cache: Fix a regression in 2.4.25 for the forward proxy case by
80 computing and using the same entity key according to when the cache
81 checks, loads and saves the request.
82 PR 60577. [Yann Ylavic]
84 *) mod_proxy_hcheck: Don't validate timed out responses. [Yann Ylavic]
86 *) mod_proxy_hcheck: Ensure thread-safety when concurrent healthchecks are
87 in use (ProxyHCTPsize > 0). PR 60071. [Yann Ylavic, Jim Jagielski]
89 *) core: %{DOCUMENT_URI} used in nested SSI expressions should point to the
90 URI originally requsted by the user, not the nested documents URI. This
91 restores the behavior of this variable to match the "legacy" SSI parser.
92 PR60624. [Hank Ibell <hwibell gmail.com>]
94 *) mod_proxy_fcgi: Add ProxyFCGISetEnvIf to fixup CGI environment
95 variables just before invoking the FastCGI. [Eric Covener,
98 *) mod_proxy: Allow the per-request environment variable "no-proxy" to
99 be used as an alternative to ProxyPass /path !. This is primarily
100 to set exceptions for ProxyPass specified in <Location> context.
101 Use SetEnvIf, not SetEnv. [Eric Covener]
103 *) mod_proxy_fcgi: Return to 2.4.20-and-earlier behavior of leaving
104 a "proxy:fcgi://" prefix in the SCRIPT_FILENAME environment variable by
105 default. Add ProxyFCGIBackendType to allow the type of backend to be
106 specified so these kinds of fixups can be restored without impacting
107 FPM. PR60576 [Eric Covener, Jim Jagielski]
109 *) mod_ssl: work around leaks on (graceful) restart. [Yann Ylavic]
111 *) mod_ssl: Add support for OpenSSL 1.1.0. [Rainer Jung]
113 *) Don't set SO_REUSEPORT unless ListenCoresBucketsRatio is greater
114 than zero. [Eric Covener]
116 *) mod_http2: moving session cleanup to pre_close hook to avoid races with
117 modules already shut down and slave connections still operating.
120 *) mod_lua: Support for Lua 5.3
122 *) mod_proxy_http2: support for ProxyPreserverHost directive. [Stefan Eissing]
124 *) mod_http2: fix for crash when running out of memory.
125 [Robert Swiecki <robert swiecki.net>, Stefan Eissing]
127 *) mod_proxy_fcgi: Return HTTP 504 rather than 503 in case of proxy timeout.
130 *) mod_http2: not counting file buckets again stream max buffer limits.
131 Effectively transfering static files in one step from slave to master
132 connection. [Stefan Eissing]
134 *) mod_http2: comforting ap_check_pipeline() on slave connections
135 to facilitate reuse (see https://github.com/icing/mod_h2/issues/128).
136 [Stefan Eissing, reported by Armin Abfalterer]
138 *) mod_http2: http/2 streams now with state handling/transitions as defined
139 in RFC7540. Stream cleanup/connection shutdown reworked to become easier
140 to understand/maintain/debug. Added many asserts on state and cleanup
141 transitions. [Stefan Eissing]
143 *) mod_auth_digest: Use an anonymous shared memory segment by default,
144 preventing startup failure after unclean shutdown. PR 54622.
147 *) mod_filter: Fix AddOutputFilterByType with non-content-level filters.
148 PR 58856. [Micha Lenk <micha lenk.info>]
150 *) mod_watchdog: Fix semaphore leak over restarts. [Jim Jagielski]
152 *) mod_http2: regression fix on PR 59348, on graceful restart, ongoing
153 streams are finished normally before the final GOAWAY is sent.
154 [Stefan Eissing, <slavko gmail.com>]
156 *) mod_proxy: Allow the per-request environment variable "no-proxy" to
157 be used as an alternative to ProxyPass /path !. This is primarily
158 to set exceptions for ProxyPass specified in <Location> context.
159 Use SetEnvIf, not SetEnv. PR 60458. [Eric Covener]
161 *) mod_http2: fixes PR60599, sending proper response for conditional requests
162 answered by mod_cache. [Jeff Wheelhouse, Stefan Eissing]
164 *) mod_http2: rework of stream resource cleanup to avoid a crash in a close
165 of a lingering connection. Prohibit special file bucket beaming for
166 shared buckets. Files sent in stream output now use the stream pool
167 as read buffer, reducing memory footprint of connections.
168 [Yann Ylavic, Stefan Eissing]
170 *) mod_proxy_fcgi, mod_fcgid: Fix crashes in ap_fcgi_encoded_env_len() when
171 modules add empty environment variables to the request. PR 60275.
172 [<alex2grad AT gmail.com>]
174 *) mod_http2: fix for possible page fault when stream is resumed during
175 session shutdown. [sidney-j-r-m (github)]
177 *) mod_http2: fix for h2 session ignoring new responses while already
178 open streams continue to have data available. [Stefan Eissing]
180 *) mod_http2: adding support for MergeTrailers directive. [Stefan Eissing]
182 *) mod_http2: limiting DATA frame sizes by TLS record sizes in use on the
183 connection. Flushing outgoing frames earlier. [Stefan Eissing]
185 *) mod_http2: cleanup beamer registry on server reload. PR 60510.
186 [Pavel Mateja <pavel verotel.cz>, Stefan Eissing]
188 *) mod_proxy_{ajp,fcgi}: Fix a possible crash when reusing an established
189 backend connection, happening with LogLevel trace2 or higher configured,
190 or at any log level with compilers not detected as C99 compliant (e.g.
191 MSVC on Windows). [Yann Ylavic]
193 *) mod_ext_filter: Don't interfere with "error buckets" issued by other
194 modules. PR 60375. [Eric Covener, Lubos Uhliarik]
196 *) mod_http2: fixes https://github.com/icing/mod_h2/issues/126 e.g. beam
197 bucket lifetime handling when data is sent over temporary pools.
200 Changes with Apache 2.4.25
202 *) Fix some build issues related to various modules.
205 Changes with Apache 2.4.24 (not released)
207 *) SECURITY: CVE-2016-8740 (cve.mitre.org)
208 mod_http2: Mitigate DoS memory exhaustion via endless
210 [Naveen Tiwari <naveen.tiwari@asu.edu> and CDF/SEFCOM at Arizona State
211 University, Stefan Eissing]
213 *) SECURITY: CVE-2016-2161 (cve.mitre.org)
214 mod_auth_digest: Prevent segfaults during client entry allocation when
215 the shared memory space is exhausted.
216 [Maksim Malyutin <m.malyutin dsec.ru>, Eric Covener, Jacob Champion]
218 *) SECURITY: CVE-2016-0736 (cve.mitre.org)
219 mod_session_crypto: Authenticate the session data/cookie with a
220 MAC (SipHash) to prevent deciphering or tampering with a padding
221 oracle attack. [Yann Ylavic, Colm MacCarthaigh]
223 *) SECURITY: CVE-2016-8743 (cve.mitre.org)
224 Enforce HTTP request grammar corresponding to RFC7230 for request lines
225 and request headers, to prevent response splitting and cache pollution by
226 malicious clients or downstream proxies. [William Rowe, Stefan Fritsch]
228 *) Validate HTTP response header grammar defined by RFC7230, resulting
229 in a 500 error in the event that invalid response header contents are
230 detected when serving the response, to avoid response splitting and cache
231 pollution by malicious clients, upstream servers or faulty modules.
232 [Stefan Fritsch, Eric Covener, Yann Ylavic]
234 *) core: Mitigate [f]cgi CVE-2016-5387 "httpoxy" issues.
235 [Dominic Scheirlinck <dominic vendhq.com>, Yann Ylavic]
237 *) mod_rewrite: Limit runaway memory use by short circuiting some kinds of
238 looping RewriteRules when the local path significantly exceeds
239 LimitRequestLine. PR 60478. [Jeff Wheelhouse <apache wheelhouse.org>]
241 *) mod_ratelimit: Allow for initial "burst" amount at full speed before
242 throttling: PR 60145 [Andy Valencia <ajv-etradanalhos vsta.org>,
245 *) mod_socache_memcache: Provide memcache stats to mod_status.
248 *) http_filters: Fix potential looping in new check_headers() due to new
249 pattern of ap_die() from http header filter. Explicitly clear the
250 previous headers and body.
252 *) core: Drop Content-Length header and message-body from HTTP 204 responses.
253 PR 51350 [Luca Toscano]
255 *) mod_proxy: Honor a server scoped ProxyPass exception when ProxyPass is
256 configured in <Location>, like in 2.2. PR 60458.
259 *) mod_lua: Fix default value of LuaInherit directive. It should be
260 'parent-first' instead of 'none', as per documentation. PR 60419
263 *) core: New directive HttpProtocolOptions to control httpd enforcement
264 of various RFC7230 requirements. [Stefan Fritsch, William Rowe]
266 *) core: Permit unencoded ';' characters to appear in proxy requests and
267 Location: response headers. Corresponds to modern browser behavior.
270 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
272 *) core: Correctly parse an IPv6 literal host specification in an absolute
273 URL in the request line. [Stefan Fritsch]
275 *) core: New directive RegisterHttpMethod for registering non-standard
276 HTTP methods. [Stefan Fritsch]
278 *) mod_socache_memcache: Pass expiration time through to memcached.
279 [Faidon Liambotis <paravoid debian.org>, Joe Orton]
281 *) mod_cache: Use the actual URI path and query-string for identifying the
282 cached entity (key), such that rewrites are taken into account when
283 running afterwards (CacheQuickHandler off). PR 21935. [Yann Ylavic]
285 *) mod_http2: new directive 'H2EarlyHints' to enable sending of HTTP status
286 103 interim responses. Disabled by default. [Stefan Eissing]
288 *) mod_ssl: Fix quick renegotiation (OptRenegotiaton) with no intermediate
289 in the client certificate chain. PR 55786. [Yann Ylavic]
291 *) event: Allow to use the whole allocated scoreboard (up to ServerLimit
292 slots) to avoid scoreboard full errors when some processes are finishing
293 gracefully. Also, make gracefully finishing processes close all
294 keep-alive connections. PR 53555. [Stefan Fritsch]
296 *) mpm_event: Don't take over scoreboard slots from gracefully finishing
297 threads. [Stefan Fritsch]
299 *) mpm_event: Free memory earlier when shutting down processes.
302 *) mod_status: Display the process slot number in the async connection
303 overview. [Stefan Fritsch]
305 *) mod_dir: Responses that go through "FallbackResource" might appear to
306 hang due to unterminated chunked encoding. PR58292. [Eric Covener]
308 *) mod_dav: Fix a potential cause of unbounded memory usage or incorrect
309 behavior in a routine that sends <DAV:response>'s to the output filters.
312 *) mod_http2: new directive 'H2PushResource' to enable early pushes before
313 processing of the main request starts. Resources are announced to the
314 client in Link headers on a 103 early hint response.
315 All responses with status code <400 are inspected for Link header and
316 trigger pushes accordingly. 304 still does prevent pushes.
317 'H2PushResource' can mark resources as 'critical' which gives them higher
318 priority than the main resource. This leads to preferred scheduling for
319 processing and, when content is available, will send it first. 'critical'
320 is also recognized on Link headers. [Stefan Eissing]
322 *) mod_proxy_http2: uris in Link headers are now mapped back to a suitable
323 local url when available. Relative uris with an absolute path are mapped
324 as well. This makes reverse proxy mapping available for resources
325 announced in this header.
326 With 103 interim responses being forwarded to the main client connection,
327 this effectively allows early pushing of resources by a reverse proxied
328 backend server. [Stefan Eissing]
330 *) mod_proxy_http2: adding support for newly proposed 103 status code.
333 *) mpm_unix: Apache fails to start if previously crashed then restarted with
334 the same PID (e.g. in container). PR 60261.
335 [Val <valentin.bremond gmail.com>, Yann Ylavic]
337 *) mod_http2: unannounced and multiple interim responses (status code < 200)
338 are parsed and forwarded to client until a final response arrives.
341 *) mod_proxy_http2: improved robustness when main connection is closed early
342 by resetting all ongoing streams against the backend.
345 *) mod_http2: allocators from slave connections are released earlier,
346 resulting in less overall memory use on busy, long lived connections.
349 *) mod_remoteip: Pick up where we left off during a subrequest rather
350 than running with the modified XFF but original TCP address.
353 *) http: Respond with "408 Request Timeout" when a timeout occurs while
354 reading the request body. [Yann Ylavic]
356 *) mod_http2: connection shutdown revisited: corrected edge cases on
357 shutting down ongoing streams, changed log warnings to be less noisy
358 when waiting on long running tasks. [Stefan Eissing]
360 *) mod_http2: changed all AP_DEBUG_ASSERT to ap_assert to have them
361 available also in normal deployments. [Stefan Eissing]
363 *) mod_http2/mod_proxy_http2: 100-continue handling now properly implemented
364 up to the backend. Reused HTTP/2 proxy connections with more than a second
365 not used will block request bodies until a PING answer is received.
366 Requests headers are not delayed by this, since they are repeatable in
367 case of failure. This greatly increases robustness, especially with
368 busy server and/or low keepalive connections. [Stefan Eissing]
370 *) mod_proxy_http2: fixed duplicate symbols with mod_http2.
373 *) mod_http2: rewrite of how responses and trailers are transferred between
374 master and slave connection. Reduction of internal states for tasks
375 and streams, stability. Heuristic id generation for slave connections
376 to better keep promise of connection ids unique at given point int time.
377 Fix for mod_cgid interop in high load situtations.
378 Fix for handling of incoming trailers when no request body is sent.
381 *) mod_http2: fix suspended handling for streams. Output could become
382 blocked in rare cases. [Stefan Eissing]
384 *) mpm_winnt: Prevent a denial of service when the 'data' AcceptFilter is in
385 use by replacing it with the 'connect' filter. PR 59970. [Jacob Champion]
387 *) mod_cgid: Resolve a case where a short CGI response causes a subsequent
388 CGI to be killed prematurely, resulting in a truncated subsequent
389 response. [Eric Covener]
391 *) mod_proxy_hcheck: Set health check URI and expression correctly for health
392 check worker. PR 60038 [zdeno <zdeno@scnet.sk>]
394 *) mod_http2: if configured with nghttp2 1.14.0 and onward, invalid request
395 headers will immediately reset the stream with a PROTOCOL error. Feature
396 logged by module on startup as 'INVHD' in info message.
399 *) mod_http2: fixed handling of stream buffers during shutdown.
402 *) mod_reqtimeout: Fix body timeout disabling for CONNECT requests to avoid
403 triggering mod_proxy_connect's AH01018 once the tunnel is established.
406 *) ab: Set the Server Name Indication (SNI) extension on outgoing TLS
407 connections (unless -I is specified), according to the Host header (if
408 any) or the requested URL's hostname otherwise. [Yann Ylavic]
410 *) mod_proxy_fcgi: avoid loops when ProxyErrorOverride is enabled
411 and the error documents are proxied. PR 55415. [Luca Toscano]
413 *) mod_proxy_fcgi: read the whole FCGI response even when the content
414 has not been modified (HTTP 304) or in case of a precondition failure
415 (HTTP 412) to avoid subsequent bogus reads and confusing
416 error messages logged. [Luca Toscano]
418 *) mod_http2: h2 status resource follows latest draft, see
419 http://www.ietf.org/id/draft-benfield-http2-debug-state-01.txt
422 *) mod_http2: handling graceful shutdown gracefully, e.g. handling existing
423 streams to the end. [Stefan Eissing]
425 *) mod_proxy_{http,ajp,fcgi}: don't reuse backend connections with data
426 available before the request is sent. PR 57832. [Yann Ylavic]
428 *) mod_proxy_balancer: Prevent redirect loops between workers within a
429 balancer by limiting the number of redirects to the number balancer
430 members. PR 59864 [Ruediger Pluem]
432 *) mod_proxy: Correctly consider error response codes by the backend when
433 processing failonstatus. PR 59869 [Ruediger Pluem]
435 *) mod_dav: Add dav_get_provider_name() function to obtain the name
436 of the provider from mod_dav. [Graham Leggett]
438 *) mod_dav: Add support for childtags to dav_error.
439 [Jari Urpalainen <jari.urpalainen nokia.com>]
441 *) mod_proxy_fcgi: Fix 2.4.23 breakage for mod_rewrite per-dir and query
442 string showing up in SCRIPT_FILENAME. PR59815
444 *) mod_include: Fix a potential memory misuse while evaluating expressions.
445 PR59844. [Eric Covener]
447 *) mod_http2: new H2CopyFiles directive that changes treatment of file
448 handles in responses. Necessary in order to fix broken lifetime handling
449 in modules such as mod_wsgi.
451 *) mod_http2: removing timeouts on master connection while requests are
452 being processed. Requests may timeout, but the master only times out when
453 no more requests are active. [Stefan Eissing]
455 *) mod_http2: fixes connection flush when answering SETTINGS without any
456 stream open. [Moto Ishizawa <@summerwind>, Stefan Eissing]
458 Changes with Apache 2.4.23
460 *) mod_ssl: reset client-verify state of ssl when aborting renegotiations.
461 [Erki Aring <erki@example.ee>, Stefan Eissing]
463 *) mod_sed: Fix 'x' command processing. [Christophe Jaillet]
465 *) configure: Fix ./configure edge-case failures around dependencies
466 of mod_proxy_hcheck. [William Rowe, Ruediger Pluem, Jeff Trawick]
468 Changes with Apache 2.4.22
470 *) mod_http2: fix for request abort when connections drops, introduced in
473 Changes with Apache 2.4.21
475 *) ab: Use caseless matching for HTTP tokens (e.g. content-length). PR 59111.
478 *) mod_http2: more rigid error handling in DATA frame assembly, leading
479 to deterministic connection errors if assembly fails.
480 [Stefan Eissing, Pal Nilsen <https://github.com/maedox>]
482 *) abs: Include OPENSSL_Applink when compiling on Windows, to resolve
483 failures under Visual Studio 2015 and other mismatched MSVCRT flavors.
484 PR59630 [Jan Ehrhardt <phpdev ehrhardt.nl>]
486 *) mod_ssl: Add "no_crl_for_cert_ok" flag to SSLCARevocationCheck directive
487 to opt-in previous behaviour (2.2) with CRLs verification when checking
488 certificate(s) with no corresponding CRL. [Yann Ylavic]
490 *) mpm_event, mpm_worker: Fix computation of MinSpareThreads' lower bound
491 according the number of listeners buckets. [Yann Ylavic]
493 *) Add ap_cstr_casecmp[n]() - placeholder of apr_cstr_casecmp[n] functions
494 for case-insensitive C/POSIX-locale token comparison.
495 [Jim Jagielski, William Rowe, Yann Ylavic, Branko Čibej]
497 *) mod_userdir: Constify and save a few bytes in the conf pool when
498 parsing the "UserDir" directive. [Christophe Jaillet]
500 *) mod_cache: Fix (max-stale with no '=') and enforce (check
501 integers after '=') Cache-Control header parsing.
504 *) core: Add -DDUMP_INCLUDES configtest option to show the tree
505 of Included configuration files.
506 [Jacob Champion <champion.pxi gmail.com>]
508 *) mod_proxy_fcgi: Avoid passing a filename of proxy:fcgi:// as
509 SCRIPT_FILENAME to a FastCGI server. PR59618.
510 [Jacob Champion <champion.pxi gmail.com>]
512 *) mod_dav: Add dav_get_provider_name() function to obtain the name
513 of the provider from mod_dav.
514 [Jari Urpalainen <jari.urpalainen nokia.com>]
516 *) mod_proxy_http2: properly care for HTTP2 flow control of the frontend
517 connection is HTTP/1.1. [Patch supplied by Evgeny Kotkov]
519 *) mod_http2: improved cleanup of connection/streams/tasks to always
520 have deterministic order regardless of event initiating it. Addresses
521 reported crashes due to memory read after free issues.
524 *) mod_ssl: Correct the interaction between SSLProxyCheckPeerCN and newer
525 SSLProxyCheckPeerName directives since release 2.4.5, such that disabling
526 either disables both, and that enabling either triggers the new, more
527 comprehensive SSLProxyCheckPeerName behavior. Only a single configuration
528 remains to enable the legacy behavior, which is to explicitly disable
529 SSLProxyCheckPeerName, and enable SSLProxyCheckPeerCN. [William Rowe]
531 *) mod_include: add the <!--#comment ...> syntax in order to include comments
532 in a SSI file. [Christophe Jaillet based on a suggestion from Rob]
534 *) mod_http2: improved event handling for suspended streams, responses
535 and window updates. [Stefan Eissing]
537 *) mod_proxy_hcheck: Provide for dynamic background health
538 checks on reverse proxies associated with BalancerMember
539 workers. [Jim Jagielski]
541 *) mod_http2: Fix async write issue that led to selection of wrong timeout
542 vs. keepalive timeout selection for idle sessions. [Stefan Eissing]
544 *) mod_http2: checking LimitRequestLine, LimitRequestFields and
545 LimitRequestFieldSize configurated values for incoming streams. Returning
546 HTTP status 431 for too long/many headers fields and 414 for a too long
547 pseudo header. [Stefan Eissing]
549 *) mod_http2: tracking conn_rec->current_thread on slave connections, so
550 that mod_lua finds the correct one. Fixes PR 59542. [Stefan Eissing]
552 *) mod_proxy_http2: new experimental http2 proxy module for h2: and h2c: proxy
553 urls. Part of the httpd mod_proxy framework, common settings apply.
554 Requests from the same HTTP/2 frontend connection against the same backend
555 are aggregated on a single connection.
558 *) mod_http2: slave connections have conn_rec->aborted flag set when a stream
559 has been reset by the client. [Stefan Eissing]
561 *) mod_http2: merge of some 2.4.x adaptions re filters on slave connections.
562 Small fixes in bucket beams when forwarding file buckets. Output handling
563 on master connection uses less FLUSH and passes automatically when more
564 than half of H2StreamMaxMemSize bytes have accumulated.
565 Workaround for http: when forwarding partial file buckets to keep the
566 output filter from closing these too early. [Stefan Eissing]
568 *) mod_http2: elimination of fixed master connection buffer for TLS
569 connections. New scratch bucket handling optimized for TLS write sizes.
570 File bucket data read directly into scratch buffers, avoiding one
571 copy. Non-TLS connections continue to pass buckets unchanged to the core
572 filters to allow sendfile() usage. [Stefan Eissing]
574 *) mod_http2/mod_proxy_http2: h2_request.c is no longer shared between these

576 reference used in logging is now clear. [Stefan Eissing]
578 *) Scoreboard: Fix a regression in 2.4.20 that causes wrong request data
579 to be displayed on the status page. PR 59333. [Yann Ylavic, William Rowe]
581 *) mod_http2: fixed a bug that caused mod_proxy_http2 to be called for window
582 updates on requests it had already reported done. Added synchronization
583 on early connection/stream close that lets ongoing requests safely drain
587 *) mod_http2: scoreboard updates that summarize the h2 session (and replace

589 in shutdown/done phase. [Stefan Eissing]
591 *) mod_http2: new "bucket beam" technology to transport buckets across
592 threads without buffer copy. Delaying response start until flush or
593 enough body data has been accumulated. Overall significantly smaller
594 memory footprint. [Stefan Eissing]
596 *) core: New CGIVar directive can configure REQUEST_URI to represent the
597 current URI being processed instead of always the original request.
600 *) scoreboard/status: Restore behavior of showing workers' previous Client,
601 VHost and Request values when idle, like in 2.4.18 and earlier.
603 *) mod_http2: r->protocol changed to "HTTP/2.0" (was "HTTP/2") as this will

652 urls. Uses backend connections for concurrent requests if frontend
653 connection is http2 as well.

657 several stages of initialization and connection handling. See
658 mod_ssl_openssl.h. [Jeff Trawick]
660 *) mod_http2: disabling PUSH when client sends GOAWAY. Slave connections are
661 reused for several requests, improved performance and better memory use.
664 *) mod_rewrite: Don't implicitly URL-escape the original query string
665 when no substitution has changed it (like PR50447 but server context)

675 the request has been fully read. PR 59045. [Yann Ylavic]
677 *) ap_expr: expression support for variable HTTP2=on|off. [Stefan Eissing]
679 *) mod_http2: give control to async mpm for keepalive timeouts only when
680 no streams are open and even if only after 1 sec delay. Under load, event
681 mpm discards connections otherwise too quickly. [Stefan Eissing]
683 *) mod_ssl: Don't lose track of the SSL context if an unlikely failure occurs
684 in ssl_init_ssl_connection(). [Graham Leggett]

687 literal question marks in their names. PR 58777. [Eric Covener]
689 *) event: use pre_connection hook to properly initialize connection state for
690 slave connections. use protocol_switch hook to initialize server config
691 early based on SNI selected vhost.
694 *) hostname: Test and log useragent_host per-request across various modules,
695 including the scoreboard, expression and rewrite engines, setenvif,
696 authz_host, access_compat, custom logging, ssl and REMOTE_HOST variables.
697 PR55348 [William Rowe]
699 *) core: Track the useragent_host per-request when mod_remoteip or similar
700 modules track a per-request useragent_ip. Modules should be updated
701 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().
704 *) core: fix a bug in <UnDefine ...> directive processing. When used, the last
705 <Define...>'ed variable was also withdrawn. PR 59019
708 *) mod_http2: Accept-Encoding is, when present on the initiating request,
709 added to push promises. This lets compressed content work in pushes.
710 by the client. [Stefan Eissing]
712 *) mod_http2: fixed possible read after free when streams were cancelled early
713 by the client. [Stefan Eissing]
715 *) mod_http2: fixed possible deadlock during connection shutdown. Thanks to
716 @FrankStolle for reporting and getting the necessary data.
719 *) mod_http2: fixed apr_uint64_t formatting in a log statement to user proper
720 APR def, thanks to @Sp1l.
722 *) mod_http2: number of worker threads allowed to a connection is adjusting
723 dynamically. Starting with 4, the number is doubled when streams can be
724 served without block on http/2 connection flow. The number is halfed, when
725 the server has to wait on client flow control grants.
726 This can happen with a maximum frequency of 5 times per second.
727 When a connection occupies too many workers, repeatable requests
728 (GET/HEAD/OPTIONS) are cancelled and placed back in the queue. Should that
729 not suffice and a stream is busy longer than the server timeout, the
730 connection will be aborted with error code ENHANCE_YOUR_CALM.
731 This does *not* limit the number of streams a client may open, rather the
732 number of server threads a connection might use.
735 *) mod_http2: allowing link header to specify multiple "rel" values,
736 space-separated inside a quoted string. Prohibiting push when Link
737 parameter "nopush" is present.
740 *) mod_http2: reworked connection state handling. Idle connections accept a
741 GOAWAY from the client without further reply. Otherwise the
742 module makes a best effort to send one last GOAWAY to the client.
744 *) mod_http2: the values from standard directives Timeout and KeepAliveTimeout
745 properly are applied to http/2 connections.
748 *) mod_http2: idle connections are returned to async mpms. new hook
749 "pre_close_connection" used to send GOAWAY frame when not already done.
750 Setting event mpm server config "by hand" for the main connection to
751 the correct negotiated server.
754 *) mod_http2: keep-alive blocking reads are done with 1 second timeouts to
755 check for MPM stopping. Will announce early GOAWAY and finish processing
756 open streams, then close.
759 *) mod_http2: bytes read/written on slave connections are reported via the
760 optional mod_logio functions. Fixes PR 58871.
762 *) prefork: Initialize the POD when running in ONE_PROCESS (or -X) mode to
763 avoid a crash. [Jan Kaluza, Yann Ylavic]
765 *) mod_ssl: When SSLVerify is disabled (NONE), don't force a renegotiation if
766 the SSLVerifyDepth applied with the default/handshaken vhost differs from
767 the one applicable with the finally selected vhost. [Yann Ylavic]
769 *) core: Ensure that httpd exits with an error status when the MPM fails
770 to run. [Yann Ylavic]
772 *) mod_ssl: Fix a possible memory leak on restart for custom [EC]DH params.
773 [Jan Kaluza, Yann Ylavic]
775 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
776 to OCSP responders through a HTTP proxy. [Ruediger Pluem]
778 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
779 had to be issued because the remote closed the previous/reusable one
780 during idle (keep-alive) time. [Yann Ylavic]
782 *) mod_cache_socache: Fix a possible cached entity body corruption when it
783 is received from an origin server in multiple batches and forwarded by
784 mod_proxy. [Yann Ylavic]
786 *) core: Add expression support to SetHandler.
789 *) mod_remoteip: Prevent an external proxy from presenting an internal
790 proxy. PR 55962. [Mike Rumph]
792 *) core: Prevent a server crash in case of an invalid CONNECT request with
793 a custom error page for status code 400 that uses server side includes.

797 APR_TIMEUP and preserving connection state for later retry.
800 *) mod_ssl: Save some TLS record (application data) fragmentations by
801 including the last and subsequent suitable buckets when coalescing.
804 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
805 "Error dispatching request", when the cause appears to be
806 due to the client closing the connection.
807 PR58118. [Tobias Adolph <adolph lrz.de>]
809 *) mod_cgid: Message AH02550, failure to flush a response to the client,
810 is now logged at TRACE1 level to match the underlying core output filter
811 severity. [Eric Covener]
813 *) mime.types: add common extension "m4a" for MPEG 4 Audio.
814 PR 57895 [Dylan Millikin <dylan.millikin gmail.com>]
816 *) Added many log numbers to log statements that had none.
819 *) mod_log_config: Add GlobalLog to allow a globally defined log to
820 be inherited by virtual hosts that define a CustomLog.
823 *) mod_http2: connections how keep a "push diary" where hashes of already
824 pushed resources are kept. See directive H2PushDiarySize for managing this.
825 Push diaries can be initialized by clients via the "Cache-Digest" request
826 header. This carries a base64url encoded. compressed Golomb set as described
827 in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
828 Introduced a status handler for HTTP/2 connections, giving various counters
829 and statistics about the current connection, plus its cache digest value
830 in a JSON record. Not a replacement for more HTTP/2 in the server status.
832 <Location "/http2-status">
833 SetHandler http2-status
837 *) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
838 did not always reach the client, causing some to fail the next request.
839 Fixed calculation of last stream id accepted as described in rfc7540.
840 Reading in KEEPALIVE state now correctly shown in scoreboard.
841 Fixed possible race in connection shutdown after review by Ylavic.
842 Fixed segfault on connection shutdown, callback ran into a semi dismantled session.
845 *) mod_http2: Added support for experimental accept-push-policy draft
846 (https://tools.ietf.org/html/draft-ruellan-http-accept-push-policy-00). Clients
847 may now influence server pushes by sending accept-push-policy headers.
850 *) mod_http2: new r->subprocess_env variables HTTP2 and H2PUSH, set to "on"
851 when available for request.
854 *) mod_http2: fixed bug in input window size calculation by moving chunked
855 request body encoding into later stage of processing. Fixes PR 58825.
858 *) core: new hook "pre_close_connection" which is run before the lingering
859 close of connections is started. This gives protocol handlers one last
860 chance to use a connection before it goes down.
863 *) mod_status/scoreboard: showing connection protocol in new column, new
864 ap_update_child_status methods for updating server/description. mod_ssl
865 sets vhost negotiated by servername directly.
868 Changes with Apache 2.4.18
870 *) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
871 if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
874 *) mod_http2: connection level window for flow control is set to protocol
875 maximum of 2GB-1, preventing window exhaustion when sending data on many
876 streams with higher cumulative window size.
877 Reducing write frequency unless push promises need to be flushed.
880 *) mod_http2: required minimum version of libnghttp2 is 1.2.1
883 *) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
884 In earlier version of httpd, you can explicitelly set the 'flusher' parameter
885 to 'flush' as a workaround. (i.e. flusher=flush)
886 Add documentation for the 'flusher' parameter when defining a proxy worker.
889 *) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
890 to only staple responses with certificate status "good". [Kaspar Brand]
892 *) mod_http2: new directive 'H2PushPriority' to allow priority specifications
893 on server pushed streams according to their content-type.
896 *) mod_http2: fixes crash on connection abort for a busy connection.
897 fixes crash on a request that did not produce any response.
900 *) mod_http2: trailers are sent after response body if set in request_rec
901 trailers_out before the end-of-request bucket is sent through the
902 output filters. [Stefan Eissing]
904 *) mod_http2: incoming trailers (headers after request body) are properly
905 forwarded to the processing engine. [Stefan Eissing]
907 *) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
908 pushes a server/virtual host. Pushes are initiated by the presence
909 of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
911 *) mod_http2: write performance of http2 improved for larger resources,
912 especially static files. [Stefan Eissing]
914 *) core: if the first HTTP/1.1 request on a connection goes to a server that
915 prefers different protocols, these protocols are announced in a Upgrade:
916 header on the response, mentioning the preferred protocols.

920 to control TLS record sizes during connection lifetime.
923 *) mod_http2: new directive 'H2ModernTLSOnly' to enforce security
924 requirements of RFC 7540 on TLS connections. [Stefan Eissing]
926 *) core: add ap_get_protocol_upgrades() to retrieve the list of protocols
927 that a client could possibly upgrade to. Use in first request on a
928 connection to announce protocol choices. [Stefan Eissing]
930 *) mod_http2: reworked deallocation on connection shutdown and worker
931 abort. Separate parent pool for all workers. worker threads are joined
932 on planned worker shutdown. [Yann Ylavic, Stefan Eissing]
934 *) mod_ssl: when receiving requests for other virtual hosts than the handshake
935 server, the SSL parameters are checked for equality. With equal
936 configuration, requests are passed for processing. Any change will trigger
937 the old behaviour of "421 Misdirected Request".
938 SSL now remembers the cipher suite that was used for the last handshake.
939 This is compared against for any vhost/directory cipher specification.
940 Detailed examination of renegotiation is only done when these do not
942 Renegotiation is 403ed when a master connection is present. Exact reason
943 is given additionally in a request note. [Stefan Eissing]

955 via new 'QualifyRedirectURL' directive.
957 *) core: Limit to ten the number of tolerated empty lines between request,
958 and consume them before the pipelining check to avoid possible response
959 delay when reading the next request without flushing. [Yann Ylavic]
961 *) mod_ssl: Extend expression parser registration to support ssl variables
962 in any expression using mod_rewrite syntax "%{SSL:VARNAME}" or function
963 syntax "ssl(VARNAME)". [Rainer Jung]
965 Changes with Apache 2.4.17

3977 capture a stale backend response, perform If-Modified-Since requests
3978 against the backend, and serving from the cache all 304 responses.

4000 variable being echoed or set to be decoded and then encoded as separate
4001 steps. PR47686 [Graham Leggett]
4003 *) mod_cache: Add a discrete commit_entity() provider function within the
4004 mod_cache provider interface which is called to indicate to the
4005 provider that caching is complete, giving the provider the opportunity
4006 to commit temporary files permanently to the cache in an atomic
4007 fashion. Replace the inconsistent use of error cleanups with a formal
4008 set of pool cleanups attached to a subpool, which is destroyed on error.
4011 *) mod_cache: Change the signature of the store_body() provider function
4012 within the mod_cache provider interface to support an "in" brigade
4013 and an "out" brigade instead of just a single input brigade. This
4014 gives a cache provider the option to consume only part of the brigade
4015 passed to it, rather than the whole brigade as was required before.
4016 This fixes an out of memory and a request timeout condition that would
4017 occur when the original document was a large file. Introduce
4018 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
4019 the amount of data to attempt to cache at a time. [Graham Leggett]

4029 to return cached content at all, and respect a "Cache-Control:
4030 no-cache" header from a client. Previously, "no-cache" would
4031 behave like "max-age=0". [Graham Leggett]

4034 of misusing the per-request configuration. Fixes a segfault on trunk

4937 *) mod_lbmethod_heartbeat: New module to load balance mod_proxy workers
4938 based on heartbeats. [Paul Querna]
4940 *) mod_heartmonitor: New module to collect heartbeats, and write out a file
4941 so that other modules can load balance traffic as needed. [Paul Querna]
4943 *) mod_heartbeat: New module to generate multicast heartbeats to know if a
4944 server is online. [Paul Querna]
4946 *) mod_buffer: Honour the flush bucket and flush the buffer in the
4947 input filter. Make sure that metadata buckets are written to
4948 the buffer, not to the final brigade. [Graham Leggett]
4950 *) mod_buffer: Optimise the buffering of heap buckets when the heap
4951 buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
4954 *) mod_buffer: Optional support for buffering of the input and output
4955 filter stacks. Can collapse many small buckets into fewer larger
4956 buckets, and prevents excessively small chunks being sent over
4957 the wire. [Graham Leggett]
4959 *) mod_privileges: new module to make httpd on Solaris privileges-aware
4960 and to enable different virtualhosts to run with different
4961 privileges and Unix user/group IDs [Nick Kew]
4963 *) mod_mem_cache: this module has been removed. [William Rowe]
4965 *) authn/z: Remove mod_authn_default and mod_authz_default.
4968 *) authz: Fix handling of authz configurations, make default authz
4969 logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
4970 and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge
4971 directives. [Chris Darroch]
4973 *) mod_authn_core: Prevent crash when provider alias created to
4974 provider which is not yet registered. [Chris Darroch]
4976 *) mod_authn_core: Add AuthType of None to support disabling
4977 authentication. [Chris Darroch]

4980 constrain their use to conform with that of other access control
4981 and authorization directives. [Chris Darroch]

5007 faked directly after login. [Graham Leggett]
5009 *) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
5010 within the output headers and error output headers, so that the
5011 session is maintained across redirects. [Graham Leggett]
5013 *) mod_auth_form: Make sure the logged in user is populated correctly
5014 after a form login. Fixes a missing REMOTE_USER variable directly
5015 following a login. [Graham Leggett]
5017 *) mod_session_cookie: Make sure that cookie attributes are correctly
5018 included in the blank cookie when cookies are removed. This fixes an
5019 inability to log out when using mod_auth_form. [Graham Leggett]
5021 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
5022 null value. [David Shane Holden <dpejesh apache.org>]
5024 *) core, authn/z: Determine registered authn/z providers directly in
5025 ap_setup_auth_internal(), which allows optional functions that just
5026 wrapped ap_list_provider_names() to be removed from authn/z modules.
5029 *) authn/z: Convert common provider version strings to macros.
5032 *) core: When testing for slash-terminated configuration paths in
5033 ap_location_walk(), don't look past the start of an empty string
5034 such as that created by a <Location ""> directive.
5037 *) core, mod_proxy: If a kept_body is present, it becomes safe for
5038 subrequests to support message bodies. Make sure that safety
5039 checks within the core and within the proxy are not triggered
5040 when kept_body is present. This makes it possible to embed
5041 proxied POST requests within mod_include. [Graham Leggett]
5043 *) mod_auth_form: Make sure the input filter stack is properly set
5044 up before reading the login form. Make sure the kept body filter
5045 is correctly inserted to ensure the body can be read a second
5046 time safely should the authn be successful. [Graham Leggett,
5049 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
5050 hook instead of during fixups. Add a safety check to ensure the
5051 filters cannot be inserted more than once. [Graham Leggett,
5054 *) ap_cache_cacheable_headers_out() will (now) always
5055 merge an error headers _before_ clearing them and _before_
5056 merging in the actual entity headers and doing normal
5057 hop-by-hop cleansing. [Dirk-Willem van Gulik].
5059 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
5060 for both in- and out-put headers; and replace it by a single
5061 ap_cache_cacheable_headers() wrapped in a in- and out-put
5062 specific ap_cache_cacheable_headers_in()/out(). The latter
5063 which will also merge error and ensure content-type. To keep
5064 cache modules consistent with ease. This API change bumps
5065 up the minor MM by one [Dirk-Willem van Gulik].
5067 *) Move the KeptBodySize directive, kept_body filters and the
5068 ap_parse_request_body function out of the http module and into a
5069 new module called mod_request, reducing the size of the core.
5072 *) mod_dbd: Handle integer configuration directive parameters with a
5075 *) Change the directives within the mod_session* modules to be valid
5076 both inside and outside the location/directory sections, as
5077 suggested by wrowe. [Graham Leggett]
5079 *) mod_auth_form: Add a module capable of allowing end users to log
5080 in using an HTML form, storing the credentials within mod_session.
5083 *) Add a function to the http filters that is able to parse an HTML
5084 form request with the type of application/x-www-form-urlencoded.
5087 *) mod_session_crypto: Initialise SSL in the post config hook.
5088 [Ruediger Pluem, Graham Leggett]
5090 *) mod_session_dbd: Add a session implementation capable of storing
5091 session information in a SQL database via the dbd interface. Useful
5092 for sites where session privacy is important. [Graham Leggett]
5094 *) mod_session_crypto: Add a session encoding implementation capable
5095 of encrypting and decrypting sessions wherever they may be stored.
5096 Introduces a level of privacy when sessions are stored on the
5097 browser. [Graham Leggett]
5099 *) mod_session_cookie: Add a session implementation capable of storing
5100 session information within cookies on the browser. Useful for high
5101 volume sites where server bound sessions are too resource intensive.
5104 *) mod_session: Add a generic session interface to unify the different
5105 attempts at saving persistent sessions across requests.
5108 *) core, authn/z: Avoid calling access control hooks for internal requests
5109 with configurations which match those of initial request. Revert to
5110 original behaviour (call access control hooks for internal requests
5111 with URIs different from initial request) if any access control hooks or
5112 providers are not registered as permitting this optimization.
5113 Introduce wrappers for access control hook and provider registration
5114 which can accept additional mode and flag data. [Chris Darroch]
