2 Changes with Apache 2.5.1
4 *) mod_remoteip: make proxy-protocol work on slave connections, e.g. in HTTP/2
5 requests. See also https://github.com/roadrunner2/mod-proxy-protocol/issues/6
8 *) mod_md: fixes error in renew window calculation that may lead to mod_md running
9 watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
11 *) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
12 outside the configured MDs are free to be answered by other handlers. This allows
13 co-existance between mod_md and other ACME clients on the same server (implements PR62189).
14 [Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
16 *) mod_md: Fix compilation with OpenSSL before version 1.0.2. [Rainer Jung]
18 *) core: Create a conn_config_t structure to hold an extendable core config rather
19 than consuming the whole pointer with the connection socket. [Graham Leggett]
21 *) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
22 building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
24 *) mod_http2: discourage gzip/brotli content encoding on http2-status responses as
25 they are inserted into the reponse when filters are already done. [Stefan Eissing]
27 *) core: adding defines to allow interworking with honggfuzz without
28 further patches. [Stefan Eissing, Robert Swiecki]
30 *) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
31 inadvertently modify the Content-Type _response_ header. Applies to
32 Content-Type only and likely to only affect static file responses.
35 *) mod_cgi: Improve AH01215 messages to make it more clear that the message is
36 the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
38 *) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
39 header. PR 61983. [Hank Ibell <hwibell gmail.com>]
41 *) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
42 management of the base server domains outside VirtualHosts. By default, this is "off",
43 e.g. mod_md will not manage certificates or perform https: redirections on the
44 base server. [Stefan Eissing]
46 *) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
47 ECONNRESET during the client accept() to not trigger graceful shutdown of
48 the child process. [Eric Covener]
51 - MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
52 possibly because this fails if the OID is already configured in ```openssl.cnf```, see
53 [here](https://github.com/openssl/openssl/issues/2795).
54 - Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
55 - Changing MDMustStaple triggers certificate renewal.
56 - More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
57 idea what it is talking about. Some people report misbehaviour here.
58 - Re-enabled support for md_get_credentials() function that was used in older mod_ssl
59 patch, so that people with old patched servers get a chance to upgrade.
60 [Stefan Eissing, Yann Ylavic]
62 *) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
65 *) mod_md: fixed mem pool usage for auto-added server names. Added
66 error logging of exact ACME response when challenges failed.
69 *) mod_dumpio: do nothing below log level TRACE7. [Yann Ylavic]
71 *) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
72 mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
74 *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
75 PR 61857. [Yann Ylavic]
77 *) mod_proxy_html: fix handling of <meta http-equiv> elements.
80 *) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
81 Add higher level WARNING log when initial request to ACME server fails, mentioning
82 some advice. [Stefan Eissing]
84 *) mod_md: name change in configuration directives. The old names are still working
85 in this version, so you can safely upgrade. They will give warnings in the log and
86 will disappear in the immediate future. ManagedDomain is now MDomain,
87 <ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
89 *) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
90 for new server config merge flag. Denying global, only once used directives
91 inside a SSLPolicyDefine. [Stefan Eissing]
93 *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
94 should be accepted after the authorization scheme. \t are also tolerated.
97 *) mod_http2: fixed unfair scheduling when number of active connections
98 exceeded the scheduling fifo capacity. [Stefan Eissing]
100 *) core: Support zone/scope in IPv6 link-local addresses in Listen and
101 VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
103 *) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
104 only necessary work for mod_ssl to be also happy with the configuration.
107 *) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
108 testing. Avoid problems with our build system that had problems after the latest
109 changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
112 *) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
113 includes a colon character. PR 52644. [Joe Orton]
115 *) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
116 persisted accross child process changes and staging is reset on reloads. Changed
117 MDCertificateAgreement url checks. As long as the CA reports that the account has
118 an agreement, no further checking is done. Existing accounts need no changes when
119 a new agreement comes out. [Stefan Eissing]
121 *) mod_watchdog: Correct some log messages. [Rainer Jung]
123 *) mod_noloris: complete build setup. [Rainer Jung]
125 *) mod_md: fix static compilation. [Rainer Jung]
127 *) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
129 *) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
131 Changes with Apache 2.5.0-alpha
133 *) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
134 auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
135 restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
136 process. [Stefan Eissing]
138 *) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
139 Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
141 *) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
144 - Use of the new module flag
145 - Removed obsolete function from interface to mod_ssl.
146 - Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
147 - MDRequireHttps now happens before any Redirect.
150 *) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
151 overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
152 and certificate/key pickup from mod_md. [Stefan Eissing]
154 *) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
155 HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
157 *) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
158 update_policies.py to update manually from Mozilla JSON definitions at
159 https://statics.tls.security.mozilla.org/server-side-tls-conf.json
163 - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
164 new certificates are requested with the OCSP Must Staple extension.
165 - Known limitation: when the server is configured to ditch and restart child processes, for example
166 after a certain number of connections/requests, the mod_md watchdog instance might migrate
167 to a new child process. Since not all its state is persisted, some messsages might appear a
168 second time in the logs.
169 - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
170 is used - which negates that a https: port exists. Also, a warning is logged if no
171 VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
173 - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
175 - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
176 a changed mod_ssl patch (v5) to take effect.
177 - compatibility with libressl
180 *) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
181 some minor bugfixes, twiddle the build system to avoid non-pic code generation.
184 *) mod_ssl: Adding option to set a list of addr:port specs, as used in VirtualHosts
185 to enable SSLEngine for all matching hosts. Updated documentation. [Stefan Eissing]
188 - various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
189 someone already used percent configurations, it is advised to change these to a new value,
190 reload and change back to the wanted ones.
191 - various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
192 - mod_md version removed from top level md_store.json file. The store has its own format version
193 to facilitate upgrades.
197 Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
200 *) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
201 core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
202 in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
204 *) mod_md: new module for managing domains across VirtualHosts with ACME protocol
205 implementation for automated certificate signup and renewal. Default CA is
206 the test area of Let's Encrypt right now, so certificates root will not be valid.
207 Will be switched to the real service endpoint rather soon. If you need it now,
208 configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
211 *) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
212 from each set of unmatched rewrite conditions.
215 *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
216 and <IfModule> to be quoted. This is primarily for the benefit of
217 <IfFile>. [Eric Covener]
219 *) Introduce request taint checking framework to prevent privilege
220 hijacking through .htaccess. [Nick Kew]
222 *) Add <IfDirective> and <IfSection> directives. [Joe Orton]
224 *) When using mod_status with the Event MPM, report the number of requests
225 associated with an active connection in the "ACC" field. Previously
226 zero was always reported with this MPM. PR60647. [Eric Covener]
228 *) mod_remoteip: When overriding the useragent address from X-Forwarded-For,
229 zero out what had been initialized as the connection-level port. PR59931.
230 [Hank Ibell <hwibell gmail.com>]
232 *) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
235 *) http: Allow unknown response status' lines returned in the form of
236 "HTTP/x.x xxx Status xxx". [Yann Ylavic]
238 *) core: Add <IfFile> configuration section to allow any file on disk to be
239 used as a conditional. [Edward Lu, Eric Covener]
241 *) mod_crypto: Add the all purpose crypto filters with support for HLS.
244 *) core: Drop an invalid Last-Modified header value coming
245 from a FCGI/CGI script instead of replacing it with Unix epoch.
246 Warn the users about Last-Modified header value replacements
247 and violations of the RFC.
248 [Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
250 *) mod_dav: Allow other modules to become providers and add ACLs
252 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
254 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
255 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
256 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
257 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
259 *) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
260 header as commanded by http-wg. [Stefan Eissing]
262 *) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
263 AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
265 *) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
266 or sockets. [Graham Leggett]
268 *) core: Extend support for setting aside data from the network input filter
269 to any connection or request input filter. [Graham Leggett]
271 *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
273 *) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
276 *) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
277 to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
280 *) mod_cache: Consider Cache-Control: s-maxage in expiration
281 calculations. [Eric Covener]
283 *) mod_cache: Allow caching of responses with an Expires header
284 in the past that also has Cache-Control: max-age or s-maxage.
285 PR55156. [Eric Covener]
287 *) mod_session: Introduce SessionExpiryUpdateInterval which allows to
288 configure the session/cookie expiry's update interval. PR 57300.
289 [Paul Spangler <paul.spangler ni.com>]
291 *) core: Extend support for asynchronous write completion from the
292 network filter to any connection or request filter. [Graham Leggett]
294 *) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
295 more documented since dec 2012 (r1415960). [Christophe Jaillet]
297 *) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
298 after other resource-level filters. [Eric Covener]
300 *) http: Don't remove the Content-Length of zero from a HEAD response if
301 it comes from an origin server, module or script. [Yann Ylavic]
303 *) http: Add support for RFC2324/RFC7168. [Graham Leggett]
305 *) mod_authn_core: Add expression support to AuthName and AuthType.
308 *) suexec: Filter out the HTTP_PROXY environment variable because it is
309 treated as alias for http_proxy by some programs. [Stefan Fritsch]
311 *) mod_proxy_http: Don't establish or reuse a backend connection before pre-
312 fetching the request body, so to minimize the delay between it is supposed
313 to be alive and the first bytes sent: this is a best effort to prevent the
314 backend from closing because of idle or keepalive timeout in the meantime.
315 Also, handle a new "proxy-flushall" environment variable which allows to
316 flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
318 *) core: Define and UnDefine are no longer permitted in
319 directory context. Previously they would always be evaulated
320 as the configuration was read without regard for the directory
321 context. [Eric Covener]
323 *) config: For directives that do not expect any arguments, enforce
324 that none are specified in the configuration file.
325 [Joachim Zobel <jzobel heute-morgen.de>, Eric Covener]
327 *) mod_rewrite: Improve 'bad flag delimeters' startup error by showing
328 how the input was tokenized. PR 56528. [Edward Lu <Chaosed0 gmail.com>]
330 *) mod_proxy: Don't put non balancer-member workers in error state by
331 default for connection or 500/503 errors, and honor status=+I for
332 any error. PR 48388. [Yann Ylavic]
334 *) ap_expr: Add filemod function for checking file modification dates
337 *) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
338 r1608202. [Eric Covener]
340 *) apreq: Content-Length header should be always interpreted as a decimal.
341 Leading 0 could be erroneously considered as an octal value. PR 56598.
342 [Chris Card <ctcard hotmail com>]
344 *) mod_proxy: Now allow for 191 character worker names, with non-fatal
345 errors if name is truncated. PR53218. [Jim Jagielski]
347 *) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
348 for channel bindings. [Simo Sorce <simo redhat.com>]
350 *) mod_proxy_wstunnel: Concurrent websockets messages could be
351 lost or delayed with ProxyWebsocketAsync enabled.
352 [Edward Lu <Chaosed0 gmail.com>]
354 *) core, mod_info: Add compiled and loaded PCRE versions to version
355 number display. [Rainer Jung]
357 *) mod_authnz_ldap: Return LDAP connections to the pool before the handler
358 is run, instead of waiting until the end of the request. [Eric Covener]
360 *) mod_proxy_html: support automatic detection of doctype and processing
361 of FPIs. PR56285 [Micha Lenk <micha lenk info>, Nick Kew]
363 *) core: Add ap_mpm_resume_suspended() API to allow a suspended connection
365 [Artem <artemciy gmail.com>, Edward Lu <Chaosed0 gmail.com>]
367 *) core: Add ap_mpm_register_socket_callback_timeout() API. [Eric Covener]
369 *) mod_proxy_wstunnel: Honor ProxyWebsocketIdleTimeout in asynchronous
370 processing mode. [Eric Covener]
372 *) mod_authnz_ldap: Fail explicitly when the filter is too long. Remove
373 unnecessary apr_pstrdup() and strlen(). [Graham Leggett]
375 *) Add the ldap-search option to mod_authnz_ldap, allowing authorization
376 to be based on arbitrary expressions that do not include the username.
379 *) Add the ldap function to the expression API, allowing LDAP filters and
380 distinguished names based on expressions to be escaped correctly to
381 guard against LDAP injection. [Graham Leggett]
383 *) Add module mod_ssl_ct, which provides an implementation of Certificate
384 Transparency (RFC 6962) for httpd. [Jeff Trawick]
386 *) mod_proxy_wstunnel: Avoid sending error responses down an upgraded
387 websockets connection as it is being close down. [Eric Covener]
389 *) mod_proxy_wstunnel: Allow the administrator to cap the amount
390 of time a synchronous websockets connection stays idle with
391 ProxyWebsocketIdleTimeout. [Eric Covener]
393 *) mod_proxy_wstunnel: Change to opt-in for asynchronous support, adding
394 directives ProxyWebsocketAsync and ProxyWebsocketAsyncDelay.
397 *) mod_proxy_wstunnel: Stop leaking websockets backend connections under
398 event MPM (trunk-only). [Eric Covener]
400 *) mod_proxy_http: Add detach_backend hook (potentially usable
401 in other proxy scheme handlers). [Jeff Trawick]
403 *) mod_deflate: Add DeflateAlterETag to control how the ETag
404 is modified. The 'NoChange' parameter mimics 2.2.x behavior.
405 PR 45023, PR 39727. [Eric Covener]
407 *) mod_dir: Default to 2.2-like behavior and skip execution when method is
408 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
410 *) mod_rewrite: Rename the handler that does per-directory internal
411 redirects to "rewrite-redirect-handler" from "redirect-handler" so
412 it is less ambiguous and less likely to be reused. [Eric Covener]
414 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
415 default limit of 10000 iterations, and allowing each rule to change its
416 limit. [Eric Covener]
418 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
421 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
422 [Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]
424 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
425 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.

436 [Eric Covener, Toshikuni Fukaya <toshikuni-fukaya cybozu co jp>]
438 *) core: ensure any abnormal exit is reported to stderr if it's a tty.
441 *) mod_lua: Let the Inter-VM get/set functions work with a global
442 shared memory pool instead of a per-process pool. [Daniel Gruno]
444 *) ldap: Support ldaps when using the Microsoft LDAP SDK.
445 PR 54626. [Jean-Frederic Clere]
447 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
448 to avoid performance problems when subgroups aren't in use. [Eric Covener]
450 *) mod_syslog: New module implementing syslog ap_error_log provider.
451 Previously, this code was part of core, now it's in separate module.
454 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
455 syslog support from core to new mod_syslog. [Jan Kaluza]
457 *) mod_status, mod_echo: Fix the display of client addresses.
458 They were truncated to 31 characters which is not enough for IPv6 addresses.
459 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
461 *) core: merge AllowEncodedSlashes from the base configuration into
462 virtual hosts. [Eric Covener]
464 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
467 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
470 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
471 been configured with -D Z_PREFIX, which redefines the token "deflate".
474 *) mod_auth_digest: Use the secret when generating nonces in all cases and
475 not only when AuthName is used in .htaccess files (this change may cause
476 problems if used with round robin load balancers). Don't regenerate the
477 secret on graceful restarts. PR 54637 [Stefan Fritsch]
479 *) core: Stop the HTTP_IN filter from attempting to write error buckets
480 to the output filters, which is bogus in the proxy case. Create a
481 clean mapping from APR codes to HTTP status codes, and use it where
482 needed. [Graham Leggett]
484 *) mod_proxy: Ensure network errors detected by the proxy are returned as
485 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
486 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.

489 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
490 <alejandro.alvarez.ayllon cern.ch>]
492 *) mod_ldap: LDAP connections used for authentication were not respecting
493 LDAPConnectionPoolTimeout. PR 54587
495 *) core: Add option to add valgrind support. Use it to reduce false positive
496 warnings in mod_ssl. [Stefan Fritsch]
498 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
499 Cache the result of the most recent password hash verification for every
500 keep-alive connection. This saves some expensive calculations.
503 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
504 MSIE 3. [Stefan Fritsch]
506 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
507 conformance or to only log the found problems. [Stefan Fritsch]
511 *) core: Add LogLevelOverride directive that allows to override the
512 loglevel for clients from certain IPs. This also works for things
513 like the SSL handshake where <If> LogLevel ... </If> is evaluated
514 too late. [Stefan Fritsch]
516 *) core: Add new directive Warning to issue warnings from a configuration
517 file. Both Warning and Error now generate a timestamped log message.
520 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
521 variables. [Stefan Fritsch]
523 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
524 support. [Stefan Fritsch]
526 *) mod_allowhandlers: New module to forbid specific handlers for specific
527 directories. [Stefan Fritsch]
529 *) mod_systemd: New module, for integration with systemd on Linux.
530 [Jan Kaluza <jkaluza redhat.com>]
532 *) WinNT MPM: Store pid and generation for each thread in scoreboard
533 to allow tracking of threads from exiting children via mod_status
534 or other such mechanisms. [Jeff Trawick]

539 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
540 - mod_ldap: shared memory cache
541 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
544 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
545 setuid/setgid capability bits rather than a setuid root binary.
548 *) suexec: Add support for logging to syslog as an alternative to logging
549 to a file; configure --without-suexec-logfile --with-suexec-syslog.
552 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
