-*- coding: utf-8 -*-
Changes with Apache 2.5.1
*) mod_http2: fixed a bug that prevented proper stream cleanup when connection
throttling was in place. Stream resets by clients on streams initiated by them
are counted as possible trigger for throttling. [Stefan Eissing]
*) mod_http2/mpm_event: Fixes the behaviour when a HTTP/2 connection has nothing
more to write with streams ongoing (flow control block). The timeout waiting
for the client to send WINODW_UPDATE was incorrectly KeepAliveTimeout and not
Timeout as it should be. Fixes PR 63534. [Yann Ylavic, Stefan Eissing]
*) mod_ssl/mod_md: reversing dependency by letting mod_ssl offer hooks for
adding certificates and keys to a virtual host. An additional hook allows
answering special TLS connections as used in ACME challenges.
Adding 2 new hooks for init/get of OCSP stapling status information when
other modules want to provide those. Falls back to own implementation with
same behaviour as before.
[Stefan Eissing]
*) mod_ssl: use OPENSSL_init_ssl() to initialise OpenSSL on versions 1.1+.
[Graham Leggett]
*) mod_proxy_http2: adding support for handling trailers in both directions. PR 63502.
[Stefan Eissing]
*) mod_reqtimeout: Fix default rates missing (not applied) in 2.4.39.
PR 63325. [Yann Ylavic]
*) mod_ldap: Avoid potential crashes in util_ldap_cache_module_kill() or other
LDAP related functions during graceful restart of a busy server. PR63305.
[Martin Fúsek <mfusek newps.cz>]
*) mod_cache: Fix parsing of quoted Cache-Control token arguments.
PR 63288. [Yann Ylavic]
*) mod_md: Store permissions are enforced on file creation, enforcing restrictions in
spite of umask. Fixes <https://github.com/icing/mod_md/issues/117>. [Stefan Eissing]
*) mod_ssl: Correctly restore SSL verify state after TLSv1.3 PHA failure.
[Michael Kaufmann <mail michael-kaufmann.ch>]
*) Merge consecutive slashes in URL's. Opt-out with `MergeSlashes OFF`.
[Eric Covener]
*) mod_proxy/ssl: Cleanup per-request SSL configuration anytime a backend
connection is recycled/reused to avoid a possible crash with some SSLProxy
configurations in <Location> or <Proxy> context. PR 63256. [Yann Ylavic]
*) mod_mime: Add `MimeOptions` directive to allow Content-Type or all metadata
detection to use only the last (right-most) file extension or to be
disabled per-dir. [Eric Covener]
*) MPMs unix: bind the bucket number of each child to its slot number, for a
more efficient per bucket maintenance. [Yann Ylavic]
*) http: Fix possible empty response with mod_ratelimit for HEAD requests.
PR 63192. [Yann Ylavic]
*) mod_cache_socache: Avoid reallocations and be safe with outgoing data
lifetime. [Yann Ylavic]
*) mod_reqtimeout: Allow to configure (TLS-)handshake timeouts.
PR 61310. [Yann Ylavic]
*) mod_auth_digest: Fix a race condition. Authentication with valid credentials could be
refused in case of concurrent accesses from different users.
PR 63124 [Simon Kappel <simon.kappel axis.com>]
*) mod_ssl: Don't unset FIPS mode on restart unless it's forced by
configuration (SSLFIPS on) and not active by default in OpenSSL.
PR 63136. [Yann Ylavic]
*) mod_ssl: give mod_md the chance to override certificate after ALPN protocol
negotiation. [Stefan Eissing]
*) mod_proxy_wstunnel: Fix websocket proxy over UDS.
PR 62932 <pavel dcmsys.com>
*) mod_negociation: LanguagePriority should be case-insensitive in order to
match AddLanguage behavior. PR 39730 [Christophe Jaillet]
*) mod_session: Always decode session attributes early. [Hank Ibell]
*) core: Incorrect values for environment variables are substituted when
multiple environment variables are specified in a directive. [Hank Ibell]
*) core: Split out the ability to parse wildcard files and directories
from the Include/IncludeOptional directives into a generic set of
functions ap_dir_nofnmatch() and ap_dir_fnmatch(). [Graham Leggett]
*) mod_ssl: Fix mod_authz provider for "require ssl" directive to check correctly
on HTTP/2 connections. Fixes PR 62654. [Stefan Eissing]
*) mod_ssl: clear *SSL errors before loading certificates and checking
afterwards. Otherwise errors are reported when other SSL using modules
are in play. Fixes PR 62880. [Michael Kaufmann]
*) core: Ensure that aborted connections are logged as such. PR 62823
[Arnaud Grandville <contact@grandville.net>]
*) mpm_event: Stop issuing AH00484 "server reached MaxRequestWorkers..." when
there are still idle threads available. When there are less idle threads than
MinSpareThreads, issue new one-time message AH10159. Matches worker MPM.
[Eric Covener]
*) mod_proxy_scgi, mod_proxy_uwsgi: improve error handling when sending the
body of the response. [Jim Jagielski]
*) mod_session_cookie: avoid duplicate Set-Cookie header in the response.
[Emmanuel Dreyfus <manu@netbsd.org>, Luca Toscano]
*) mod_dav_fs: Set a default DAVLockDB within the state directory.
[Joe Orton]
*) core: Add DefaultStateDir and layout-specific state directory
created at "make install". [Joe Orton]
*) ab: Add client certificate support. [Graham Leggett]
*) mod_proxy_hcheck: Fix issues with TCP health checks. PR 61499
[Dominik Stillhard <dominik.stillhard united-security-providers.ch>]
*) MPMs: Initialize all runtime/asynchronous objects on a dedicated pool and
before signals handling to avoid lifetime issues on restart or shutdown.
PR 62658. [Yann Ylavic]
*) core: Add StrictHostCheck to allow ucnonfigured hostnames to be
rejected. [Eric Covener]
*) mod_status: Cumulate CPU time of exited child processes in the
"cu" and "cs" values. Add CPU time of the parent process to the
"c" and "s" values.
[Rainer Jung]
*) mod_status: Add cumulated response duration time in milliseconds.
[Rainer Jung]
*) mod_status: Complete the data shown for async MPMs in "auto" mode.
Added number of processes, number of stopping processes and number
of busy and idle workers. [Rainer Jung]
*) mod_proxy: Improve the balancer member data shown in mod_status when
"ProxyStatus" is "On": add "busy" count and show byte counts in auto
mode always in units of kilobytes. [Rainer Jung]
*) mod_proxy: If ProxyPassReverse is used for reverse mapping of relative
redirects, subsequent ProxyPassReverse statements, whether they are
relative or absolute, may fail. PR 60408. [Peter Haworth <pmh1wheel gmail.com>]
*) mod_ratelimit: Don't interfere with "chunked" encoding, fixing regression
introduced in 2.4.34. PR 62568. [Yann Ylavic]
*) mod_proxy_http: forward 100-continue, and minimize race conditions when
reusing backend connections. PR 60330. [Yann Ylavic, Jean-Frederic Clere]
*) mod_proxy: Remove load order and link dependency between mod_lbmethod_*
modules and mod_proxy. PR 62557. [Ruediger Pluem, William Rowe]
*) mod_md: more robust handling of http-01 challenges and hands-off when module
should not be involved, e.g. challenge setup by another ACME client. [Stefan Eissing]
*) ru, zh-cn and zh-tw translations of errordocs have been added.
Contributed by Alexander Gaganashvili and CodeingBoy
*) mod_userdir: If several directories are given in a UserDir directive, only files
in the first existing one are checked. If the file is not found there, the
other possible directories are not checked. The doc clearly states that they
will be checked one by one, until a match is found or an external redirect is
performed. PR 59636.
[Christophe Jaillet]
*) mod_rewrite: Only create the global mutex used by "RewriteMap prg:" when
this type of map is present in the configuration. PR62311.
[Hank Ibell <hwibell gmail.com>]
*) mod_ldap: Abort on LDAP locking errors. [Eric Covener]
*) mod_ssl: Support loading certificates and private keys from the
PKCS#11 OpenSSL engine. [Anderson Sasaki <ansasaki redhat.com>,
Joe Orton]
*) http: LimitRequestBody applies to proxied requests. [Yann Ylavic]
*) mod_logio: Add LogIOTrackTTFU and %^FU logformat to log the time
difference between request start and last request body byte read (finished upload).
[Rainer Jung]
*) mod_ssl: add support for TLSv1.3 (tested with OpenSSL v1.1.1-pre4, other libs may
need more sugar). SSL(Proxy)CipherSuite now has an optional first parameter for the
protocol the ciphers are for.
Directive "SSLVerifyClient" now triggers certificate retrieval from the client (this
is not fully tested - but fails in similar fashion as in TLSv1.2 in my setups).
Verifying the client fails exactly the same for HTTP/2 connections for all SSL protocols,
as this would need to trigger the master connection thread - which we do not support
right now.
Renegotiation of ciphers is intentionally ignored for TLSv1.3 connections. "SSLCipherSuite"
does not allow to specify TLSv1.3 ciphers in a directory context (because it cannot work) and
TLSv1.2 or lower ciphers are not relevant, as cipher suites are completely separate.
This means there is a bit if a world split when simultaneously having TLSv1.2 and TLSv1.3
connections to the same server.
[Yann Ylavic, Stefan Eissing]
*) mod_ssl: proper checks for libressl 2.07/8 and its TLSv1_3 support, see PR 62236.
[Bernard Spil <brnrd@freebsd.org>]
*) mod_cgi: Add CGIScriptTimeout to make mod_cgi's timeout per-directory and
independent of the core Timeout directive. PR 62229.
[Hank Ibell <hwibell gmail.com>]
*) mod_ssl: heavily simplified SSLPolicy. No more user defines, no propxy policies,
just the basic "modern", "intermediate" and "old" as specified by Mozilla security.
[Stefan Eissing]
*) mod_md: fixes error in renew window calculation that may lead to mod_md running
watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
*) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
outside the configured MDs are free to be answered by other handlers. This allows
co-existance between mod_md and other ACME clients on the same server (implements PR62189).
[Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
*) core: Create a conn_config_t structure to hold an extendable core config rather
than consuming the whole pointer with the connection socket. [Graham Leggett]
*) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
*) core: adding defines to allow interworking with honggfuzz without
further patches. [Stefan Eissing, Robert Swiecki]
*) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
inadvertently modify the Content-Type _response_ header. Applies to
Content-Type only and likely to only affect static file responses.
[Eric Covener]
*) mod_cgi: Improve AH01215 messages to make it more clear that the message is
the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
*) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
header. PR 61983. [Hank Ibell <hwibell gmail.com>]
*) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
management of the base server domains outside VirtualHosts. By default, this is "off",
e.g. mod_md will not manage certificates or perform https: redirections on the
base server. [Stefan Eissing]
*) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
ECONNRESET during the client accept() to not trigger graceful shutdown of
the child process. [Eric Covener]
*) mod_md v1.1.7:
- MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
possibly because this fails if the OID is already configured in ```openssl.cnf```, see
[here](https://github.com/openssl/openssl/issues/2795).
- Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
- Changing MDMustStaple triggers certificate renewal.
- More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
idea what it is talking about. Some people report misbehaviour here.
- Re-enabled support for md_get_credentials() function that was used in older mod_ssl
patch, so that people with old patched servers get a chance to upgrade.
[Stefan Eissing, Yann Ylavic]
*) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
[Eric Covener]
*) mod_md: fixed mem pool usage for auto-added server names. Added
error logging of exact ACME response when challenges failed.
[Stefan Eissing]
*) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
*) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
PR 61857. [Yann Ylavic]
*) mod_proxy_html: fix handling of <meta http-equiv> elements.
PR 58121. [Nick Kew]
*) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
Add higher level WARNING log when initial request to ACME server fails, mentioning
some advice. [Stefan Eissing]
*) mod_md: name change in configuration directives. The old names are still working
in this version, so you can safely upgrade. They will give warnings in the log and
will disappear in the immediate future. ManagedDomain is now MDomain,
<ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
*) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
for new server config merge flag. Denying global, only once used directives
inside a SSLPolicyDefine. [Stefan Eissing]
*) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
should be accepted after the authorization scheme. \t are also tolerated.
[Christophe Jaillet]
*) core: Support zone/scope in IPv6 link-local addresses in Listen and
VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
*) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
only necessary work for mod_ssl to be also happy with the configuration.
[Stefan Eissing]
*) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
testing. Avoid problems with our build system that had problems after the latest
changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
[Stefan Eissing]
*) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
includes a colon character. PR 52644. [Joe Orton]
*) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
persisted accross child process changes and staging is reset on reloads. Changed
MDCertificateAgreement url checks. As long as the CA reports that the account has
an agreement, no further checking is done. Existing accounts need no changes when
a new agreement comes out. [Stefan Eissing]
*) mod_watchdog: Correct some log messages. [Rainer Jung]
*) mod_noloris: complete build setup. [Rainer Jung]
*) mod_md: fix static compilation. [Rainer Jung]
*) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
*) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
Changes with Apache 2.5.0-alpha
*) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
process. [Stefan Eissing]
*) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
*) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
*) mod_md: v0.9.7
- Use of the new module flag
- Removed obsolete function from interface to mod_ssl.
- Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
- MDRequireHttps now happens before any Redirect.
[Stefan Eissing]
*) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
and certificate/key pickup from mod_md. [Stefan Eissing]
*) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
*) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
update_policies.py to update manually from Mozilla JSON definitions at
https://statics.tls.security.mozilla.org/server-side-tls-conf.json
[Stefan Eissing]
*) mod_md: v0.9.5:
- New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
new certificates are requested with the OCSP Must Staple extension.
- Known limitation: when the server is configured to ditch and restart child processes, for example
after a certain number of connections/requests, the mod_md watchdog instance might migrate
to a new child process. Since not all its state is persisted, some messsages might appear a
second time in the logs.
- Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
is used - which negates that a https: port exists. Also, a warning is logged if no
VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
its address list.
- New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
or temporarily.
- Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
a changed mod_ssl patch (v5) to take effect.
- compatibility with libressl
[Stefan Eissing]
*) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
some minor bugfixes, twiddle the build system to avoid non-pic code generation.
[Stefan Eissing]
*) mod_md: v0.9.1:
- various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
someone already used percent configurations, it is advised to change these to a new value,
reload and change back to the wanted ones.
- various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
- mod_md version removed from top level md_store.json file. The store has its own format version
to facilitate upgrades.
[Stefan Eissing]
*) mod_md: v0.9.0:
Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
[Stefan Eissing]
*) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
*) mod_md: new module for managing domains across VirtualHosts with ACME protocol
implementation for automated certificate signup and renewal. Default CA is
the test area of Let's Encrypt right now, so certificates root will not be valid.
Will be switched to the real service endpoint rather soon. If you need it now,
configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
[Stefan Eissing]
*) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
from each set of unmatched rewrite conditions.
[Eric Covener]
*) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
and <IfModule> to be quoted. This is primarily for the benefit of
<IfFile>. [Eric Covener]
*) Introduce request taint checking framework to prevent privilege
hijacking through .htaccess. [Nick Kew]
*) Add <IfDirective> and <IfSection> directives. [Joe Orton]
*) When using mod_status with the Event MPM, report the number of requests
associated with an active connection in the "ACC" field. Previously
zero was always reported with this MPM. PR60647. [Eric Covener]
*) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
[Eric Covener]
*) http: Allow unknown response status' lines returned in the form of
"HTTP/x.x xxx Status xxx". [Yann Ylavic]
*) core: Add <IfFile> configuration section to allow any file on disk to be
used as a conditional. [Edward Lu, Eric Covener]
*) mod_crypto: Add the all purpose crypto filters with support for HLS.
[Graham Leggett]
*) core: Drop an invalid Last-Modified header value coming
from a FCGI/CGI script instead of replacing it with Unix epoch.
Warn the users about Last-Modified header value replacements
and violations of the RFC.
[Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
*) mod_dav: Allow other modules to become providers and add ACLs
to the DAV response.
[Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
*) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
[Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
*) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
header as commanded by http-wg. [Stefan Eissing]
*) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
*) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
or sockets. [Graham Leggett]
*) core: Extend support for setting aside data from the network input filter
to any connection or request input filter. [Graham Leggett]
*) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
*) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
[Eric Covener]
*) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
[Graham Leggett]
*) mod_cache: Consider Cache-Control: s-maxage in expiration
calculations. [Eric Covener]
*) mod_cache: Allow caching of responses with an Expires header
in the past that also has Cache-Control: max-age or s-maxage.
PR55156. [Eric Covener]
*) mod_session: Introduce SessionExpiryUpdateInterval which allows to
configure the session/cookie expiry's update interval. PR 57300.
[Paul Spangler <paul.spangler ni.com>]
*) core: Extend support for asynchronous write completion from the
network filter to any connection or request filter. [Graham Leggett]
*) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
more documented since dec 2012 (r1415960). [Christophe Jaillet]
*) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
after other resource-level filters. [Eric Covener]
*) http: Don't remove the Content-Length of zero from a HEAD response if
it comes from an origin server, module or script. [Yann Ylavic]
*) http: Add support for RFC2324/RFC7168. [Graham Leggett]
*) mod_authn_core: Add expression support to AuthName and AuthType.
[Graham Leggett]
*) suexec: Filter out the HTTP_PROXY environment variable because it is
treated as alias for http_proxy by some programs. [Stefan Fritsch]
*) mod_proxy_http: Don't establish or reuse a backend connection before pre-
fetching the request body, so to minimize the delay between it is supposed
to be alive and the first bytes sent: this is a best effort to prevent the
backend from closing because of idle or keepalive timeout in the meantime.
Also, handle a new "proxy-flushall" environment variable which allows to
flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
*) core: Define and UnDefine are no longer permitted in
directory context. Previously they would always be evaulated
as the configuration was read without regard for the directory
context. [Eric Covener]
*) config: For directives that do not expect any arguments, enforce
that none are specified in the configuration file.
[Joachim Zobel <jzobel heute-morgen.de>, Eric Covener]
*) mod_rewrite: Improve 'bad flag delimeters' startup error by showing
how the input was tokenized. PR 56528. [Edward Lu <Chaosed0 gmail.com>]
*) mod_proxy: Don't put non balancer-member workers in error state by
default for connection or 500/503 errors, and honor status=+I for

[Daniel Gruno]
*) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
r1608202. [Eric Covener]

[Chris Card <ctcard hotmail com>]
*) mod_proxy: Now allow for 191 character worker names, with non-fatal
errors if name is truncated. PR53218. [Jim Jagielski]
*) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
for channel bindings. [Simo Sorce <simo redhat.com>]
*) mod_proxy_wstunnel: Concurrent websockets messages could be
lost or delayed with ProxyWebsocketAsync enabled.
[Edward Lu <Chaosed0 gmail.com>]
*) core, mod_info: Add compiled and loaded PCRE versions to version
number display. [Rainer Jung]
*) mod_authnz_ldap: Return LDAP connections to the pool before the handler
is run, instead of waiting until the end of the request. [Eric Covener]
*) mod_proxy_html: support automatic detection of doctype and processing
of FPIs. PR56285 [Micha Lenk <micha lenk info>, Nick Kew]
*) core: Add ap_mpm_resume_suspended() API to allow a suspended connection

processing mode. [Eric Covener]
*) mod_authnz_ldap: Fail explicitly when the filter is too long. Remove
unnecessary apr_pstrdup() and strlen(). [Graham Leggett]
*) Add the ldap-search option to mod_authnz_ldap, allowing authorization
to be based on arbitrary expressions that do not include the username.
[Graham Leggett]
*) Add the ldap function to the expression API, allowing LDAP filters and
distinguished names based on expressions to be escaped correctly to
guard against LDAP injection. [Graham Leggett]
*) Add module mod_ssl_ct, which provides an implementation of Certificate
Transparency (RFC 6962) for httpd. [Jeff Trawick]
*) mod_proxy_wstunnel: Avoid sending error responses down an upgraded
websockets connection as it is being close down. [Eric Covener]
*) mod_proxy_wstunnel: Allow the administrator to cap the amount
of time a synchronous websockets connection stays idle with
ProxyWebsocketIdleTimeout. [Eric Covener]
*) mod_proxy_wstunnel: Change to opt-in for asynchronous support, adding
directives ProxyWebsocketAsync and ProxyWebsocketAsyncDelay.
[Eric Covener]
*) mod_proxy_wstunnel: Stop leaking websockets backend connections under
event MPM (trunk-only). [Eric Covener]
*) mod_proxy_http: Add detach_backend hook (potentially usable
in other proxy scheme handlers). [Jeff Trawick]
*) mod_deflate: Add DeflateAlterETag to control how the ETag
is modified. The 'NoChange' parameter mimics 2.2.x behavior.
PR 45023, PR 39727. [Eric Covener]
*) mod_dir: Default to 2.2-like behavior and skip execution when method is
neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
*) mod_rewrite: Rename the handler that does per-directory internal
redirects to "rewrite-redirect-handler" from "redirect-handler" so
it is less ambiguous and less likely to be reused. [Eric Covener]
*) mod_rewrite: Protect against looping with the [N] flag by enforcing a
default limit of 10000 iterations, and allowing each rule to change its
limit. [Eric Covener]
*) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
[Jeff Trawick]
*) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
[Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]
*) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
[Jan Kaluza]
*) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
to support write completion. [Graham Leggett]
*) core: Add parse_errorlog_arg callback to ap_errorlog_provider
to allow providers to check the ErrorLog argument. [Jan Kaluza]

*) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
syslog support from core to new mod_syslog. [Jan Kaluza]
*) mod_status, mod_echo: Fix the display of client addresses.

This is done by deprecating the use of the 'client' field and using
the new 'client64' field in worker_score.

not only when AuthName is used in .htaccess files (this change may cause
problems if used with round robin load balancers). Don't regenerate the
secret on graceful restarts. PR 54637 [Stefan Fritsch]

to the output filters, which is bogus in the proxy case. Create a
clean mapping from APR codes to HTTP status codes, and use it where
needed. [Graham Leggett]

loglevel for clients from certain IPs. This also works for things
like the SSL handshake where <If> LogLevel ... </If> is evaluated
too late. [Stefan Fritsch]
