-*- coding: utf-8 -*- Changes with Apache 2.3.9 *) SECURITY: CVE-2010-1623 (cve.mitre.org) Fix a denial of service attack against mod_reqtimeout. [Stefan Fritsch] *) mod_proxy: Optimise ProxyPass within a Location so that it is stored per-directory, and chosen during the location walk. Make ProxyPass work correctly from within a LocationMatch. [Graham Leggett] *) core: Fix segfault if per-module LogLevel is on virtual host scope. PR 50117. [Stefan Fritsch] *) mod_proxy: Move the ProxyErrorOverride directive to have per directory scope. [Graham Leggett] *) mod_allowmethods: New module to deny certain HTTP methods without interfering with authentication/authorization. [Paul Querna, Igor Galić, Stefan Fritsch] *) mod_ssl: Log certificate information if client cert verification fails. PR 50094. [Lassi Tuura , Stefan Fritsch] *) htcacheclean: Teach htcacheclean to limit cache size by number of inodes in addition to size of files. Prevents a cache disk from running out of space when many small files are cached. [Graham Leggett] *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which describes more accurately what the directive does. The old name still works but logs a warning. [Stefan Fritsch] *) mod_cache: Optionally serve stale data when a revalidation returns a 5xx response, controlled by the CacheStaleOnError directive. [Graham Leggett] *) htcacheclean: Allow the listing of valid URLs within the cache, with the option to list entry metadata such as sizes and times. [Graham Leggett] *) mod_cache: Allow control over the base URL of reverse proxied requests using the CacheKeyBaseURL directive, so that the cache key can be calculated from the endpoint URL instead of the server URL. [Graham Leggett] *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate, CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire, CacheMinExpire and CacheMaxExpire can be set per directory/location. [Graham Leggett] *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and CacheReadTime can be set per directory/location. [Graham Leggett] *) core: Speed up config parsing if using a very large number of config files. PR 50002 [andrew cloudaccess net] *) mod_cache: Support the caching of HEAD requests. [Graham Leggett] *) htcacheclean: Allow the option to round up file sizes to a given block size, improving the accuracy of disk usage. [Graham Leggett] *) mod_ssl: Add authz providers for use with mod_authz_core and its RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL), 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and '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] *) mod_disk_cache: Change on-disk header file format to support the link of the device/inode of the data file to the matching header file, and to support the option of not writing a data file when the data file is empty. [Graham Leggett] *) core/mod_unique_id: Add generate_log_id hook to allow to use the ID generated by mod_unique_id as error log ID for requests. [Stefan Fritsch] *) mod_cache: Make sure that we never allow a 304 Not Modified response that we asked for to leak to the client should the 304 response be uncacheable. PR45341 [Graham Leggett] *) mod_cache: Add the cache_status hook to register the final cache decision hit/miss/revalidate. Add optional support for an X-Cache and/or an X-Cache-Detail header to add the cache status to the response. PR48241 [Graham Leggett] *) mod_authz_host: Add 'local' provider that matches connections originating on the local host. PR 19938. [Stefan Fritsch] *) Event MPM: Fix crash accessing pollset on worker thread when child process is exiting. [Jeff Trawick] *) core: For process invocation (cgi, fcgid, piped loggers and so forth) pass the system library path (LD_LIBRARY_PATH or platform-specific 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] *) mod_cache: Use a proper filter context to hold filter data instead of misusing the per-request configuration. Fixes a segfault on trunk when the normal handler is used. [Graham Leggett] *) mod_cgid: Log a warning if the ScriptSock path is truncated because it is too long. PR 49388. [Stefan Fritsch] *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing * and non-* ports on NameVirtualHost, or multiple NameVirtualHost directives for the same address:port, or NameVirtualHost directives with no matching VirtualHosts, or multiple ip-based VirtualHost sections for the same address:port. These were previously accepted with a warning, but the behavior was undefined. [Dan Poirier] *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with Allow/Deny. PR 49838. [Andrew Skalski ] *) core: DirectoryMatch can now match on the end of line character ($), and sub-directories of matched directories are no longer implicitly matched. PR49809 [Eric Covener] *) Regexps: introduce new higher-level regexp utility including parsing and executing perl-style regexp ops (e.g s/foo/bar/i) and regexp memory [Nick Kew] Changes with Apache 2.3.8 *) suexec: Support large log files. PR 45856. [Stefan Fritsch] *) core: Abort with sensible error message if no or more than one MPM is loaded. [Stefan Fritsch] *) mod_proxy: Rename erroronstatus to failonstatus. [Daniel Ruggeri ] *) mod_dav_fs: Fix broken "creationdate" property. Regression in version 2.3.7. [Rainer Jung] Changes with Apache 2.3.7 *) SECURITY: CVE-2010-1452 (cve.mitre.org) mod_dav, mod_cache, mod_session: Fix Handling of requests without a path segment. PR: 49246 [Mark Drayton, Jeff Trawick] *) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076. [Stefan Fritsch] *) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639. [Stefan Fritsch] *) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers via leveraging 100-Continue as the initial "request". [Jim Jagielski] *) core/mod_authz_core: Introduce new access_checker_ex hook that enables mod_authz_core to bypass authentication if access should be allowed by IP address/env var/... [Stefan Fritsch] *) core: Introduce note_auth_failure hook to allow modules to add support for additional auth types. This makes ap_note_auth_failure() work with mod_auth_digest again. PR 48807. [Stefan Fritsch] *) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew] *) mod_authn_cache: new module [Nick Kew] *) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch] *) Fix Windows build when using VC6. [Gregg L. Smith ] *) mod_rewrite: Allow to set environment variables without explicitly giving a value. [Rainer Jung] *) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung] *) mod_include: recognise "text/html; parameters" as text/html PR 49616 [Andrey Chernov ] *) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH PR 43906 [Nick Kew] *) Core: Extra robustness: don't try authz and segfault if authn fails to set r->user. Log bug and return 500 instead. PR 42995 [Nick Kew] *) HTTP protocol filter: fix handling of longer chunk extensions PR 49474 [] *) Update SSL cipher suite and add example for SSLHonorCipherOrder. [Lars Eilebrecht, Rainer Jung] *) move AddOutputFilterByType from core to mod_filter. This should fix nasty side-effects that happen when content_type is set more than once in processing a request, and make it fully compatible with dynamic and proxied contents. [Nick Kew] *) mod_log_config: Implement logging for sub second timestamps and request end time. [Rainer Jung] Changes with Apache 2.3.6 *) SECURITY: CVE-2009-3555 (cve.mitre.org) mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection attack when compiled against OpenSSL version 0.9.8m or later. Introduces the 'SSLInsecureRenegotiation' directive to reopen this vulnerability and offer unsafe legacy renegotiation with clients which do not yet support the new secure renegotiation protocol, RFC 5746. [Joe Orton, and with thanks to the OpenSSL Team] *) SECURITY: CVE-2009-3555 (cve.mitre.org) mod_ssl: A partial fix for the TLS renegotiation prefix injection attack by rejecting any client-initiated renegotiations. Forcibly disable keepalive for the connection if there is any buffered data readable. Any configuration which requires renegotiation for per-directory/location access control is still vulnerable, unless using OpenSSL >= 0.9.8l. [Joe Orton, Ruediger Pluem, Hartmut Keil ] *) SECURITY: CVE-2010-0408 (cve.mitre.org) mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent when request headers indicate a request body is incoming; not a case of HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola ] *) SECURITY: CVE-2010-0425 (cve.mitre.org) mod_isapi: Do not unload an isapi .dll module until the request processing is completed, avoiding orphaned callback pointers. [Brett Gervasoni , Jeff Trawick] *) core: Filter init functions are now run strictly once per request before handler invocation. The init functions are no longer run for connection filters. PR 49328. [Joe Orton] *) core: Adjust the output filter chain correctly in an internal redirect from a subrequest, preserving filters from the main request as necessary. PR 17629. [Joe Orton] *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial Response if they so choose to do so. Previously an attempt to cache a 206 was arbitrarily allowed if the response contained an Expires or Cache-Control header, and arbitrarily denied if both headers were missing. [Graham Leggett] *) core: Add microsecond timestamp fractions, process id and thread id to the error log. [Rainer Jung] *) configure: The "most" module set gets build by default. [Rainer Jung] *) configure: Building dynamic modules (DSO) by default. [Rainer Jung] *) configure: Fix broken VPATH build when using included APR.

[Pavel Kankovsky ] *) core: Add per-module and per-directory loglevel configuration. Add some more trace logging. mod_rewrite: Replace RewriteLog/RewriteLogLevel with trace log levels. mod_ssl: Replace LogLevelDebugDump with trace log levels. mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info and debug. mod_dumpio: Replace DumpIOLogLevel with trace log levels. [Stefan Fritsch] *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns title page only) when any mod_ldap directives were used in VirtualHost context. [Eric Covener] *) mod_disk_cache: Decline the opportunity to cache if the response is a 206 Partial Content. This stops a reverse proxied partial response from becoming cached, and then being served in subsequent responses. [Graham Leggett] *) mod_deflate: avoid the risk of forwarding data before headers are set. PR 49369 [Matthew Steele ] *) mod_authnz_ldap: Ensure nested groups are checked when the top-level group doesn't have any direct non-group members of attributes in AuthLDAPGroupAttribute.

[Graham Leggett] *) htcacheclean: Report additional statistics about entries deleted. PR 48944. [Mark Drayton mark markdrayton.info] *) Introduce SSLFIPS directive to support OpenSSL FIPS_mode; permits all builds of mod_ssl to use 'SSLFIPS off' for portability, but the proper build of openssl is required for 'SSLFIPS on'. PR 46270. [Dr Stephen Henson , William Rowe] *) mod_proxy_http: Log the port of the remote server in various messages. PR 48812.
