| Changes with Apache 2.4.53 |
| |
| *) core: Make sure and check that LimitXMLRequestBody fits in system memory. |
| [Ruediger Pluem, Yann Ylavic] |
| |
| *) core: Simpler connection close logic if discarding the request body fails. |
| [Yann Ylavic, Ruediger Pluem] |
| |
| *) mod_http2: preserve the port number given in a HTTP/1.1 |
| request that was Upgraded to HTTP/2. Fixes PR65881. |
| [Stefan Eissing] |
| |
| *) mod_proxy: Allow for larger worker name. PR 53218. [Yann Ylavic] |
| |
| *) dbm: Split the loading of a dbm driver from the opening of a dbm file. When |
| an attempt to load a dbm driver fails, log clearly which driver triggered |
| the error (not "default"), and what the error was. [Graham Leggett] |
| |
| *) mod_proxy: Use the maxium of front end and backend timeouts instead of the |
| minimum when tunneling requests (websockets, CONNECT requests). |
| Backend timeouts can be configured more selectively (per worker if needed) |
| as front end timeouts and typically the backend timeouts reflect the |
| application requirements better. PR 65886 [Ruediger Pluem] |
| |
| *) ap_regex: Use Thread Local Storage (TLS) to recycle ap_regexec() buffers |
| when an efficient TLS implementation is available. [Yann Ylavic] |
| |
| *) core, mod_info: Add compiled and loaded PCRE versions to version |
| number display. [Rainer Jung] |
| |
| *) mod_md: do not interfere with requests to /.well-known/acme-challenge/ |
| resources if challenge type 'http-01' is not configured for a domain. |
| Fixes <https://github.com/icing/mod_md/issues/279>. |
| [Stefan Eissing] |
| |
| *) mod_dav: Fix regression when gathering properties which could lead to huge |
| memory consumption proportional to the number of resources. |
| [Evgeny Kotkov, Ruediger Pluem] |
| |
| *) Support pcre2 (10.x) library in place of the now end-of-life pcre (8.x) |
| for regular expression evaluation. This depends on locating pcre2-config. |
| [William Rowe, Petr Pisar <ppisar redhat.com>, Rainer Jung] |
| |
| *) 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] |
| |
| *) mod_md: the status description in MDomain's JSON, exposed in the |
| md-status handler (if configured) did sometimes not carry the correct |
| message when certificates needed renew. |
| [Stefan Eissing] |
| |
| *) mpm_event: Fix a possible listener deadlock on heavy load when restarting |
| and/or reaching MaxConnectionsPerChild. PR 65769. [Yann Ylavic] |
| |
| Changes with Apache 2.4.52 |
| |
| *) SECURITY: CVE-2021-44790: Possible buffer overflow when parsing |
| multipart content in mod_lua of Apache HTTP Server 2.4.51 and |
| earlier (cve.mitre.org) |
| A carefully crafted request body can cause a buffer overflow in |
| the mod_lua multipart parser (r:parsebody() called from Lua |
| scripts). |
| The Apache httpd team is not aware of an exploit for the |
| vulnerability though it might be possible to craft one. |
| This issue affects Apache HTTP Server 2.4.51 and earlier. |

| *) SECURITY: CVE-2021-44224: Possible NULL dereference or SSRF in |
| forward proxy configurations in Apache HTTP Server 2.4.51 and |
| earlier (cve.mitre.org) |
| A crafted URI sent to httpd configured as a forward proxy |
| (ProxyRequests on) can cause a crash (NULL pointer dereference) |
| or, for configurations mixing forward and reverse proxy |
| declarations, can allow for requests to be directed to a |
| declared Unix Domain Socket endpoint (Server Side Request |
| Forgery). |
| This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 |
| (included). |

| |
| *) http: Enforce that fully qualified uri-paths not to be forward-proxied |
| have an http(s) scheme, and that the ones to be forward proxied have a |
| hostname, per HTTP specifications. [Ruediger Pluem, Yann Ylavic] |
| |
| *) configure: OpenSSL detection will now use pkg-config data from |
| .../lib64/ within the --with-ssl path. [Jean-Frederic Clere] |
| |
| *) mod_proxy_connect, mod_proxy: Do not change the status code after we |
| already sent it to the client. [Ruediger Pluem] |
| |
| *) mod_http: Correctly sent a 100 Continue status code when sending an interim |
| response as result of an Expect: 100-Continue in the request and not the |
| current status code of the request. PR 65725 [Ruediger Pluem] |
| |
| *) mod_dav: Some DAV extensions, like CalDAV, specify both document |
| elements and property elements that need to be taken into account |
| when generating a property. The document element and property element |
| are made available in the dav_liveprop_elem structure by calling |
| dav_get_liveprop_element(). [Graham Leggett] |
| |
| *) mod_dav: Add utility functions dav_validate_root_ns(), |
| dav_find_child_ns(), dav_find_next_ns(), dav_find_attr_ns() and |
| dav_find_attr() so that other modules get to play too. |
| [Graham Leggett] |
| |
| *) mpm_event: Restart stopping of idle children after a load peak. PR 65626. |
| [Yann Ylavic, Ruediger Pluem] |
| |
| *) mod_http2: fixes 2 regressions in server limit handling. |
| 1. When reaching server limits, such as MaxRequestsPerChild, the |
| HTTP/2 connection send a GOAWAY frame much too early on new |
| connections, leading to invalid protocol state and a client |
| failing the request. See PR65731. |
| The module now initializes the HTTP/2 protocol correctly and |
| allows the client to submit one request before the shutdown |
| via a GOAWAY frame is being announced. |
| 2. A regression in v1.15.24 was fixed that could lead to httpd |
| child processes not being terminated on a graceful reload or |
| when reaching MaxConnectionsPerChild. When unprocessed h2 |
| requests were queued at the time, these could stall. |
| See <https://github.com/icing/mod_h2/issues/212>. |
| [Stefan Eissing] |
| |
| *) mod_ssl: Add build support for OpenSSL v3. [Rainer Jung, |
| Stefan Fritsch, Yann Ylavic, Stefan Eissing, Joe Orton, |
| Giovanni Bechis] |
| |
| *) mod_proxy_connect: Honor the smallest of the backend or client timeout |
| while tunneling. [Yann Ylavic] |
| |
| *) mod_proxy: SetEnv proxy-nohalfclose (or alike) allows to disable TCP |
| half-close forwarding when tunneling protocols. [Yann Ylavic] |
| |
| *) core: Be safe with ap_lingering_close() called with a socket NULL-ed by |
| a third-party module. PR 65627. |
| [acmondor <bz.apache.org acmondor.ca>, Yann Ylavic] |
| |
| *) mod_md: Fix memory leak in case of failures to load the private key. |
| PR 65620 [ Filipe Casal <filipe.casal@trailofbits.com> ] |
| |
| *) mod_md: adding v2.4.8 with the following changes |
| - Added support for ACME External Account Binding (EAB). |
| Use the new directive `MDExternalAccountBinding` to provide the |
| server with the value for key identifier and hmac as provided by |
| your CA. |
| While working on some servers, EAB handling is not uniform |
| across CAs. First tests with a Sectigo Certificate Manager in |
| demo mode are successful. But ZeroSSL, for example, seems to |
| regard EAB values as a one-time-use-only thing, which makes them |
| fail if you create a seconde account or retry the creation of the |
| first account with the same EAB. |
| - The directive 'MDCertificateAuthority' now checks if its parameter |
| is a http/https url or one of a set of known names. Those are |
| 'LetsEncrypt', 'LetsEncrypt-Test', 'Buypass' and 'Buypass-Test' |
| for now and they are not case-sensitive. |
| The default of LetsEncrypt is unchanged. |
| - `MDContactEmail` can now be specified inside a `<MDomain dnsname>` |
| section. |
| - Treating 401 HTTP status codes for orders like 403, since some ACME |
| servers seem to prefer that for accessing oders from other accounts. |
| - When retrieving certificate chains, try to read the response even |
| if the HTTP Content-Type is unrecognized. |
| - Fixed a bug that reset the error counter of a certificate renewal |
| and prevented the increasing delays in further attempts. |
| - Fixed the renewal process giving up every time on an already existing |
| order with some invalid domains. Now, if such are seen in a previous |
| order, a new order is created for a clean start over again. |
| See <https://github.com/icing/mod_md/issues/268> |
| - Fixed a mixup in md-status handler when static certificate files |
| and renewal was configured at the same time. |
| |
| *) mod_md: values for External Account Binding (EAB) can |
| now also be configured to be read from a separate JSON |
| file. This allows to keep server configuration permissions |
| world readable without exposing secrets. |
| [Stefan Eissing] |
| |
| *) mod_proxy_uwsgi: Remove duplicate slashes at the beginning of PATH_INFO. |
| PR 65616. [Ruediger Pluem] |
| |
| Changes with Apache 2.4.51 |
| |
| *) SECURITY: CVE-2021-42013: Path Traversal and Remote Code |
| Execution in Apache HTTP Server 2.4.49 and 2.4.50 (incomplete |
| fix of CVE-2021-41773) (cve.mitre.org) |
| It was found that the fix for CVE-2021-41773 in Apache HTTP |
| Server 2.4.50 was insufficient. An attacker could use a path |
| traversal attack to map URLs to files outside the directories |
| configured by Alias-like directives. |
| If files outside of these directories are not protected by the |
| usual default configuration "require all denied", these requests |
| can succeed. If CGI scripts are also enabled for these aliased |
| paths, this could allow for remote code execution. |
| This issue only affects Apache 2.4.49 and Apache 2.4.50 and not |
| earlier versions. |

| |
| *) core: Add ap_unescape_url_ex() for better decoding control, and deprecate |
| unused AP_NORMALIZE_DROP_PARAMETERS flag. |
| [Yann Ylavic, Ruediger Pluem, Stefan Eissing, Joe Orton] |
| |
| Changes with Apache 2.4.50 |
| |
| *) SECURITY: CVE-2021-41773: Path traversal and file disclosure |
| vulnerability in Apache HTTP Server 2.4.49 (cve.mitre.org) |
| A flaw was found in a change made to path normalization in |
| Apache HTTP Server 2.4.49. An attacker could use a path |
| traversal attack to map URLs to files outside the expected |
| document root. |
| If files outside of the document root are not protected by |
| "require all denied" these requests can succeed. Additionally |
| this flaw could leak the source of interpreted files like CGI |
| scripts. |
| This issue is known to be exploited in the wild. |
| This issue only affects Apache 2.4.49 and not earlier versions. |

| *) SECURITY: CVE-2021-41524: null pointer dereference in h2 fuzzing |
| (cve.mitre.org) |
| While fuzzing the 2.4.49 httpd, a new null pointer dereference |
| was detected during HTTP/2 request processing, |
| allowing an external source to DoS the server. This requires a |
| specially crafted request. |
| The vulnerability was recently introduced in version 2.4.49. No |
| exploit is known to the project. |
| Credits: Apache httpd team would like to thank LI ZHI XIN from |
| NSFocus Security Team for reporting this issue. |
| |
| *) core: AP_NORMALIZE_DECODE_UNRESERVED should normalize the second dot in |
| the uri-path when it's preceded by a dot. [Yann Ylavic] |
| |
| *) mod_md: when MDMessageCmd for a 'challenge-setup:<type>:<dnsname>' |
| fails (!= 0 exit), the renewal process is aborted and an error is |
| reported for the MDomain. This provides scripts that distribute |
| information in a cluster to abort early with bothering an ACME |
| server to validate a dns name that will not work. The common |
| retry logic will make another attempt in the future, as with |
| other failures. |
| Fixed a bug when adding private key specs to an already working |
| MDomain, see <https://github.com/icing/mod_md/issues/260>. |
| [Stefan Eissing] |
| |
| *) mod_proxy: Handle UDS URIs with empty hostname ("unix:///...") as if they |
| had no hostname ("unix:/..."). [Yann Ylavic] |
| |
| *) mod_md: fixed a bug in handling multiple parallel OCSP requests. These could |
| run into an assertion which terminated (and restarted) the child process where |
| the task was running. Eventually, all OCSP responses were collected, but not |
| in the way that things are supposed to work. |
| See also <https://bz.apache.org/bugzilla/show_bug.cgi?id=65567>. |
| The bug was possibly triggered when more than one OCSP status needed updating |
| at the same time. For example for several renewed certificates after a server |
| reload. |
| |
| *) mod_rewrite: Fix UDS ("unix:") scheme for [P] rules. PR 57691 + 65590. |
| [Janne Peltonen <janne.peltonen sange.fi>] |

| *) event mpm: Correctly count active child processes in parent process if |
| child process dies due to MaxConnectionsPerChild. |
| PR 65592 [Ruediger Pluem] |
| |
| *) mod_http2: when a server is restarted gracefully, any idle h2 worker |
| threads are shut down immediately. |
| Also, change OpenSSL API use for deprecations in OpenSSL 3.0. |
| Adds all other, never proposed code changes to make a clean |
| sync of http2 sources. [Stefan Eissing] |

| |
| *) core/mod_proxy/mod_ssl: |
| Adding `outgoing` flag to conn_rec, indicating a connection is |
| initiated by the server to somewhere, in contrast to incoming |
| connections from clients. |
| Adding 'ap_ssl_bind_outgoing()` function that marks a connection |
| as outgoing and is used by mod_proxy instead of the previous |
| optional function `ssl_engine_set`. This enables other SSL |
| module to secure proxy connections. |
| The optional functions `ssl_engine_set`, `ssl_engine_disable` and |
| `ssl_proxy_enable` are now provided by the core to have backward |
| compatibility with non-httpd modules that might use them. mod_ssl |
| itself no longer registers these functions, but keeps them in its |
| header for backward compatibility. |
| The core provided optional function wrap any registered function |
| like it was done for `ssl_is_ssl`. |
| [Stefan Eissing] |

| PR 65159" added in 2.4.47. |
| This causes issue on Windows. |
| [Christophe Jaillet] |
| |
| *) mod_proxy_uwsgi: Fix PATH_INFO setting for generic worker. [Yann Ylavic] |
| |
| *) mod_md: Certificate/keys pairs are verified as matching before a renewal is accepted |
| as successful or a staged renewal is replacing the existing certificates. |
| This avoid potential mess ups in the md store file system to render the active |
| certificates non-working. [@mkauf] |
| |
| *) mod_proxy: Faster unix socket path parsing in the "proxy:" URL. |
| [Yann Ylavic] |
| |
| *) mod_ssl: tighten the handling of ALPN for outgoing (proxy) |
| connections. If ALPN protocols are provided and sent to the |
| remote server, the received protocol selected is inspected |
| and checked for a match. Without match, the peer handshake |
| fails. |
| An exception is the proposal of "http/1.1" where it is |
| accepted if the remote server did not answer ALPN with |
| a selected protocol. This accommodates for hosts that do |
| not observe/support ALPN and speak http/1.x be default. |
| |
| *) mod_proxy: Fix possible reuse/merging of Proxy(Pass)Match worker instances |
| with others when their URLs contain a '$' substitution. PR 65419 + 65429. |
| [Yann Ylavic] |
| |
| *) mod_dav: Add method_precondition hook. WebDAV extensions define |
| conditions that must exist before a WebDAV method can be executed. |
| This hook allows a WebDAV extension to verify these preconditions. |
| [Graham Leggett] |
| |
| *) Add hooks deliver_report and gather_reports to mod_dav.h. Allows other |
| modules apart from versioning implementations to handle the REPORT method. |

| server returned 2xx responses without content type. Reported by chuangwen. |
| [chuangwen, Stefan Eissing] |
| |
| *) mod_md: |
| - Domain names in `<MDomain ...>` can now appear in quoted form. |
| - Fixed a failure in ACME challenge selection that aborted further searches |
| when the tls-alpn-01 method did not seem to be suitable. |
| - Changed the tls-alpn-01 setup to only become unsuitable when none of the |
| dns names showed support for a configured 'Protocols ... acme-tls/1'. This |
| allows use of tls-alpn-01 for dns names that are not mapped to a VirtualHost. |

| PR 61820 [Ruediger Pluem, Roy T. Fielding] |
| |
| *) core: Adding SSL related inquiry functions to the server API. |
| These function are always available, even when no module providing |
| SSL is loaded. They provide their own "shadowing" implementation for |
| the optional functions of similar name that mod_ssl and impersonators |
| of mod_ssl provide. |
| This enables loading of several SSL providing modules when all but |
| one of them registers itself into the new hooks. Two old-style SSL |
| modules will not work, as they replace the others optional functions |
| with their own. |
| Modules using the old-style optional functions will continue to work |
| as core supplies its own versions of those. |
| The following has been added so far: |
| - ap_ssl_conn_is_ssl() to query if a connection is using SSL. |
| - ap_ssl_var_lookup() to query SSL related variables for a |
| server/connection/request. |
| - Hooks for 'ssl_conn_is_ssl' and 'ssl_var_lookup' where modules |
| providing SSL can install their own value supplying functions. |
| - ap_ssl_add_cert_files() to enable other modules like mod_md to provide |
| certificate and keys for an SSL module like mod_ssl. |
| - ap_ssl_add_fallback_cert_files() to enable other modules like mod_md to |
| provide a fallback certificate in case no 'proper' certificate is |
| available for an SSL module like mod_ssl. |
| - ap_ssl_answer_challenge() to enable other modules like mod_md to |
| provide a certificate as used in the RFC 8555 'tls-alpn-01' challenge |
| for the ACME protocol for an SSL module like mod_ssl. The function |
| and its hook provide PEM encoded data instead of file names. |
| - Hooks for 'ssl_add_cert_files', 'ssl_add_fallback_cert_files' and |
| 'ssl_answer_challenge' where modules like mod_md can provide providers |
| to the above mentioned functions. |
| - These functions reside in the new 'http_ssl.h' header file. |
| [Stefan Eissing] |
| |
| *) core/mod_ssl/mod_md: adding OCSP response provisioning as core feature. This |
| allows modules to access and provide OCSP response data without being tied |
| of each other. The data is exchanged in standard, portable formats (PEM encoded |
| certificates and DER encoded responses), so that the actual SSL/crypto |
| implementations used by the modules are independant of each other. |
| Registration and retrieval happen in the context of a server (server_rec) |
| which modules may use to decide if they are configured for this or not. |
| The area of changes: |
| 1. core: defines 2 functions in include/http_ssl.h, so that modules may |
| register a certificate, together with its issuer certificate for OCSP |
| response provisioning and ask for current response data (DER bytes) later. |
| Also, 2 hooks are defined that allow modules to implement this OCSP |
| provisioning. |
| 2. mod_ssl uses the new functions, in addition to what it did already, to |
| register its certificates this way. If no one is interested in providing |
| OCSP, it falls back to its own (if configured) stapling implementation. |
| 3. mod_md registers itself at the core hooks for OCSP provisioning. Depending |
| on configuration, it will accept registrations of its own certificates only, |
| all certificates or none. |
| [Stefan Eissing] |
| |
| *) mod_md: v2.4.0 with improvements and bugfixes |
| - MDPrivateKeys allows the specification of several types. Beside "RSA" plus |
| optional key lengths elliptic curves can be configured. This means you can |
| have multiple certificates for a Managed Domain with different key types. |
| With ```MDPrivateKeys secp384r1 rsa2048``` you get one ECDSA and one RSA |
| certificate and all modern client will use the shorter ECDSA, while older |
| client will get the RSA certificate. |
| Many thanks to @tlhackque who pushed and helped on this. |
| - Support added for MDomains consisting of a wildcard. Configuring |
| ```MDomain *.host.net``` will match all virtual hosts matching that pattern |
| and obtain one certificate for it (assuming you have 'dns-01' challenge |
| support configured). Addresses #239. |
| - Removed support for ACMEv1 servers. The only known installation used to |
| be Let's Encrypt which has disabled that version more than a year ago for |
| new accounts. |
| - Andreas Ulm (<https://github.com/root360-AndreasUlm>) implemented the |
| ```renewing``` call to ```MDMessageCmd``` that can deny a certificate |
| renewal attempt. This is useful in clustered installations, as |
| discussed in #233). |
| - New event ```challenge-setup:<type>:<domain>```, triggered when the |
| challenge data for a domain has been created. This is invoked before the |
| ACME server is told to check for it. The type is one of the ACME challenge |
| types. This is invoked for every DNS name in a MDomain. |
| - The max delay for retries has been raised to daily (this is like all |
| retries jittered somewhat to avoid repeats at fixed time of day). |
| - Certain error codes reported by the ACME server that indicate a problem |
| with the configured data now immediately switch to daily retries. For |
| example: if the ACME server rejects a contact email or a domain name, |
| frequent retries will most likely not solve the problem. But daily retries |
| still make sense as there might be an error at the server and un-supervised |
| certificate renewal is the goal. Refs #222. |
| - Test case and work around for domain names > 64 octets. Fixes #227. |
| When the first DNS name of an MD is longer than 63 octets, the certificate |
| request will not contain a CN field, but leave it up to the CA to choose one. |
| Currently, Lets Encrypt looks for a shorter name in the SAN list given and |
| fails the request if none is found. But it is really up to the CA (and what |
| browsers/libs accept here) and may change over the years. That is why |
| the decision is best made at the CA. |
| - Retry delays now have a random +/-[0-50]% modification applied to let |
| retries from several servers spread out more, should they have been |
| restarted at the same time of day. |
| - Fixed several places where the 'badNonce' return code from an ACME server |
| was not handled correctly. The test server 'pebble' simulates this behaviour |
| by default and helps nicely in verifying this behaviour. Thanks, pebble! |
| - Set the default `MDActivationDelay` to 0. This was confusing to users that |
| new certificates were deemed not usably before a day of delay. When clocks are |
| correct, using a new certificate right away should not pose a problem. |
| - When handling ACME authorization resources, the module no longer requires |
| the server to return a "Location" header, as was necessary in ACMEv1. |
| Fixes #216. |
| - Fixed a theoretical uninitialized read when testing for JSON error responses |
| from the ACME CA. Reported at <https://bz.apache.org/bugzilla/show_bug.cgi?id=64297>. |
| - ACME problem reports from CAs that include parameters in the Content-Type |
| header are handled correctly. (Previously, the problem text would not be |
| reported and retries could exceed CA limits.) |
| - Account Update transactions to V2 CAs now use the correct POST-AS-GET method. |
| Previously, an empty JSON object was sent - which apparently LE accepted, |
| but others reject. |

| announcement by Let's Encrypt: |
| https://community.letsencrypt.org/t/acme-v2-scheduled-deprecation-of-unauthenticated-resource-gets/74380 |
| - challenges |

| - challenge type 'tls-sni-01' has been removed as CAs do not offer this any longer |
| - supports command configuration to setup/teardown 'dns-01' challenges |
| - supports wildcard certificates when dns challenges are configured |
| - status information and monitoring |
| - a domain exposes its status at https://<domain>/.httpd/certificate-status |
| - Managed Domains are now in Apache's 'server-status' page |
| - A new handler 'md-status' exposes verbose status information in JSON format |
| - new directives |
| - "MDCertificateFile" and "MDCertificateKeyFile" to configure a |
| Managed Domain that uses static files. Auto-renewal is turned off for those. |
| - "MDMessageCmd" that is invoked on several events: 'renewed', 'expiring' and |
| 'errored'. |
| - "MDWarnWindow" directive to configure when expiration warnings shall be issued. |

| *) mod_http2: reworked deallocation on connection shutdown and worker |
| abort. Separate parent pool for all workers. worker threads are joined |
| on planned worker shutdown. [Yann Ylavic, Stefan Eissing] |
| |
| *) mod_ssl: when receiving requests for other virtual hosts than the handshake |
| server, the SSL parameters are checked for equality. With equal |
| configuration, requests are passed for processing. Any change will trigger |
| the old behaviour of "421 Misdirected Request". |
| SSL now remembers the cipher suite that was used for the last handshake. |
| This is compared against for any vhost/directory cipher specification. |
| Detailed examination of renegotiation is only done when these do not |

| *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based |
| authorization directives were mixed. [Stefan Fritsch] |
| |
| *) mod_authn_socache: change directive name from AuthnCacheProvider |
| to AuthnCacheProvideFor. The term "provider" is overloaded in |
| this module, and we should avoid confusion between the provider |
| of a backend (AuthnCacheSOCache) and the authn provider(s) for |
| which this module provides cacheing (AuthnCacheProvideFor). |
| [Nick Kew] |
| |
| *) mod_proxy_http: Allocate the fake backend request from a child pool |
| of the backend connection, instead of misusing the pool of the frontend |
| request. Fixes a thread safety issue where buckets set aside in the |
| backend connection leak into other threads, and then disappear when |
| the frontend request is cleaned up, in turn causing corrupted buckets |
| to make other threads spin. [Graham Leggett] |
| |
| *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables |
| to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and |

| still be used with the LegacyDNStringFormat argument to SSLOptions. |

| |
| *) core: Do the hook sorting earlier so that the hooks are properly sorted |

| running out of space when many small files are cached. |
| [Graham Leggett] |
| |
| *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which |

| 'ssl-require' (expressions with same syntax as SSLRequire). |
| [Stefan Fritsch] |
| |
| *) mod_ssl: Make the ssl expression parser thread-safe. It now requires |
| bison instead of yacc. [Stefan Fritsch] |
| |

| |
| *) core: For process invocation (cgi, fcgid, piped loggers and so forth) |

| variables) along with the system PATH, by default. Both should be |
| overridden together as desired using PassEnv etc; see mod_env. |
| [William Rowe] |
| |
| *) mod_cache: Introduce CacheStoreExpired, to allow administrators to |
| capture a stale backend response, perform If-Modified-Since requests |
| against the backend, and serving from the cache all 304 responses. |
| This restores pre-2.2.4 cache behavior. [William Rowe] |
| |
| *) mod_rewrite: Introduce <=, >= string comparison operators, and integer |
| comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop |
| the ambiguity of the symlink test "-ltest", introduce -h or -L as |
| symlink test operators. [William Rowe] |
| |
| *) mod_cache: Give the cache provider the opportunity to choose to cache |
| or not cache based on the buckets present in the brigade, such as the |
| presence of a FILE bucket. |
| [Graham Leggett] |
| |
| *) mod_authz_core: Allow authz providers to check args while reading the |
| config and allow to cache parsed args. Move 'all' and 'env' authz |
| providers from mod_authz_host to mod_authz_core. Add 'method' authz |
| provider depending on the HTTP method. [Stefan Fritsch] |
| |
| *) mod_include: Move the request_rec within mod_include to be |
| exposed within include_ctx_t. [Graham Leggett] |
| |
| *) mod_include: Reinstate support for UTF-8 character sets by allowing a |
| variable being echoed or set to be decoded and then encoded as separate |
| steps. PR47686 [Graham Leggett] |
| |
| *) mod_cache: Add a discrete commit_entity() provider function within the |
| mod_cache provider interface which is called to indicate to the |
| provider that caching is complete, giving the provider the opportunity |
| to commit temporary files permanently to the cache in an atomic |
| fashion. Replace the inconsistent use of error cleanups with a formal |
| set of pool cleanups attached to a subpool, which is destroyed on error. |
| [Graham Leggett] |
| |
| *) mod_cache: Change the signature of the store_body() provider function |
| within the mod_cache provider interface to support an "in" brigade |
| and an "out" brigade instead of just a single input brigade. This |
| gives a cache provider the option to consume only part of the brigade |
| passed to it, rather than the whole brigade as was required before. |
| This fixes an out of memory and a request timeout condition that would |
| occur when the original document was a large file. Introduce |
| CacheReadSize and CacheReadTime directives to mod_disk_cache to control |
| the amount of data to attempt to cache at a time. [Graham Leggett] |
| |
| *) core: Add ErrorLogFormat to allow configuring error log format, including |
| additional information that is logged once per connection or request. Add |
| error log IDs for connections and request to allow correlating error log |
| lines and the corresponding access log entry. [Stefan Fritsch] |
| |
| *) core: Disable sendfile by default. [Stefan Fritsch] |
| |
| *) mod_cache: Check the request to determine whether we are allowed |
| to return cached content at all, and respect a "Cache-Control: |
| no-cache" header from a client. Previously, "no-cache" would |
| behave like "max-age=0". [Graham Leggett] |
| |

| to newly created sub requests; as these are later on used |
| as true requests with an internal redirect. This allows for |
| mod_cache et.al. to trap the results of the redirect. |
| [Dirk-Willem van Gulik, Ruediger Pluem] |
| |
| *) mod_ldap: Add support (taking advantage of the new APR capability) |
| for ldap rebind callback while chasing referrals. This allows direct |
| searches on LDAP servers (in particular MS Active Directory 2003+) |
| using referrals without the use of the global catalog. |
| PRs 26538, 40268, and 42557 [Paul J. Reder] |
| |
| *) ApacheMonitor.exe: Introduce --kill argument for use by the |
| installer. This will permit the installation tool to remove |
| all running instances before attempting to remove the .exe. |
| [William Rowe] |
| |
| *) mod_ssl: Add support for OCSP validation of client certificates. |
| PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton] |
| |
| *) mod_serf: New module for Reverse Proxying. [Paul Querna] |
| |
| *) core: Add the option to keep aside a request body up to a certain |
| size that would otherwise be discarded, to be consumed by filters |
| such as mod_include. When enabled for a directory, POST requests |
| to shtml files can be passed through to embedded scripts as POST |
| requests, rather being downgraded to GET requests. [Graham Leggett] |
| |
| *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton] |
| |
| *) scoreboard: Correctly declare ap_time_process_request. |
| PR 43789 [Tom Donovan <Tom.Donovan acm.org>] |
| |
| *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member |
| from the connection rec, ap_get_scoreboard_worker(proc, thread) will now |
| provide the unusual legacy lookup. [William Rowe] |
| |
| *) mpm winnt: fix null pointer dereference |
| PR 42572 [Davi Arnaut] |
| |
| *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn |
| parameters to the environment. Improve portability to |
| EBCDIC machines by using apr_toupper(). [Martin Kraemer] |
| |
| *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability |
| to authorize an authenticated user via a "require ldap-group X" directive |
| where the user is not in group X, but is in a subgroup contained in X. |
| PR 42891 [Paul J. Reder] |
| |
| *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna] |
| |
| *) apxs: Enhance -q flag to print all known variables and their values |
| when invoked without variable name(s). |
| [William Rowe, Sander Temme] |
| |
| *) apxs: Eliminate run-time check for mod_so. PR 40653. |
| [David M. Lee <dmlee crossroads.com>] |
| |
| *) beos MPM: Create pmain pool and run modules' child_init hooks when |
| entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run(). |
| [Chris Darroch] |
| |
| *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that |
| cleanups registered in modules' child_init hooks are performed. |
| [Chris Darroch] |
| |
| *) Fix issue which could cause error messages to be written to access logs |
| on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>] |
| |
| *) The LockFile directive, which specifies the location of |
| the accept() mutex lockfile, is deprecated. Instead, the |
| AcceptMutex directive now takes an optional lockfile |
| location parameter, ala SSLMutex. [Jim Jagielski] |
| |
| *) mod_authn_dbd: Export any additional columns queried in the SQL select |
| into the environment with the name AUTHENTICATE_<COLUMN>. This brings |
| mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett] |
| |
| *) mod_dbd: Key the storage of prepared statements on the hex string |
| value of server_rec, rather than the server name, as the server name |
| may change (eg when the server name is set) at any time, causing |
| weird behaviour in modules dependent on mod_dbd. [Graham Leggett] |
| |
| *) mod_proxy_fcgi: Added win32 build. [Mladen Turk] |
| |
| *) sendfile_nonblocking() takes the _brigade_ as an argument, gets |
| the first bucket from the brigade, finds it not to be a FILE |
| bucket and barfs. The fix is to pass a bucket rather than a brigade. |
| [Niklas Edmundsson <nikke acc.umu.se>] |
| |
| *) mod_rewrite: support rewritemap by SQL query [Nick Kew] |
| |
| *) ap_get_server_version() has been removed. Third-party modules must |
| now use ap_get_server_banner() or ap_get_server_description(). |
| [Jeff Trawick] |
| |
| *) All MPMs: Introduce a check_config phase between pre_config and |
| open_logs, to allow modules to review interdependent configuration |
| directive values and adjust them while messages can still be logged |
| to the console. Handle relevant MPM directives during this phase |
| and format messages for both the console and the error log, as |
| appropriate. [Chris Darroch] |
| |
| *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir |
| to circumvent the symbolic link checks imposed by FollowSymLinks and |
| SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe] |
| |
| *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ] |
| configures the I/O Dump of SSL traffic, when LogLevel is set to Debug. |
| The default is none as this is far greater debugging resolution than |
| the typical administrator is prepared to untangle. [William Rowe] |
| |
| *) mod_disk_cache: If possible, check if the size of an object to cache is |
| within the configured boundaries before actually saving data. |
| [Niklas Edmundsson <nikke acc.umu.se>] |
| |
| *) Worker and event MPMs: Remove improper scoreboard updates which were |
| performed in the event of a fork() failure. [Chris Darroch] |
| |
| *) Add support for fcgi:// proxies to mod_rewrite. |
| [Markus Schiegl <ms schiegl.com>] |
| |
| *) Remove incorrect comments from scoreboard.h regarding conditional |
| loading of worker_score structure with mod_status, and remove unused |
| definitions relating to old life_status field. |
| [Chris Darroch <chrisd pearsoncmg.com>] |
| |
| *) Remove allocation of memory for unused array of lb_score pointers |
| in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>] |
| |
| *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy. |
| [Garrett Rooney, Jim Jagielski, Paul Querna] |
| |
| *) Event MPM: Fill in the scoreboard's tid field. PR 38736. |
| [Chris Darroch <chrisd pearsoncmg.com>] |
| |
| *) mod_charset_lite: Remove Content-Length when output filter can |
| invalidate it. Warn when input filter can invalidate it. |
| [Jeff Trawick] |
| |
| *) Authz: Add the new module mod_authn_core that will provide common |
| authn directives such as 'AuthType', 'AuthName'. Move the directives |
| 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias |
| into mod_authn_core. [Brad Nicholes] |
| |
| *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy' |
| into the new module mod_access_compat which can be loaded to provide |
| support for these directives. |
| [Brad Nicholes] |
| |
| *) Authz: Move the 'Require' directive from the core module as well as |
| add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>' |
| and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR' |
| logic into the authorization processing. [Brad Nicholes] |
| |
| *) Authz: Add the new module mod_authz_core which acts as the |
| authorization provider vector and contains common authz |
| directives. [Brad Nicholes] |
| |
| *) Authz: Renamed mod_authz_dbm authz providers from 'group' and |
| 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes] |
| |
| *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle |
| host-based access control provided by mod_authz_host and invoked |
| through the 'Require' directive. [Brad Nicholes] |
| |
| *) Authz: Convert all of the authz modules from hook based to |
| provider based. [Brad Nicholes] |
| |
| *) mod_cache: Add CacheMinExpire directive to set the minimum time in |
| seconds to cache a document. |
| [Brian Akins <brian.akins turner.com>, Ruediger Pluem] |
| |
| *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew] |
| |
| *) Fix typo in ProxyStatus syntax error message. |
| [Christophe Jaillet <christophe.jaillet wanadoo.fr>] |
| |
| *) Asynchronous write completion for the Event MPM. [Brian Pane] |
| |
| *) Added an End-Of-Request bucket type. The logging of a request and |
| the freeing of its pool are now done when the EOR bucket is destroyed. |
| This has the effect of delaying the logging until right after the last |
| of the response is sent; ap_core_output_filter() calls the access logger |
| indirectly when it destroys the EOR bucket. [Brian Pane] |
| |
| *) Rewrite of logresolve support utility: IPv6 addresses are now supported |
| and the format of statistical output has changed. [Colm MacCarthaigh] |
| |
| *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane] |
| |
| *) Added new connection states for handler and write completion |
| [Brian Pane] |
| |
| *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264. |
| [Justin Erenkrantz] |
| |
| *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive, |
| allowing string-valued client certificate attributes to be used for |
| access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1") |
