565N/A mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
565N/A attack when compiled against OpenSSL version 0.9.8m or later. Introduces
565N/A the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
565N/A and offer unsafe legacy renegotiation with clients which do not yet
565N/A support the new secure renegotiation protocol, RFC 5746.
565N/A [Joe Orton, and with thanks to the OpenSSL Team]
565N/A mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
565N/A by rejecting any client-initiated renegotiations. Forcibly disable
565N/A keepalive for the connection if there is any buffered data readable. Any
565N/A access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
926N/A mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
926N/A when request headers indicate a request body is incoming; not a case of
565N/A mod_isapi: Do not unload an isapi .dll module until the request
1050N/A processing is completed, avoiding orphaned callback pointers.
926N/A *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
926N/A Response if they so choose to do so. Previously an attempt to cache a 206
926N/A was arbitrarily allowed if the response contained an Expires or
838N/A Cache-Control header, and arbitrarily denied if both headers were missing.
565N/A *) core: Add microsecond timestamp fractions, process id and thread id
565N/A to the error log. [Rainer Jung]

1019N/A *) core: Add per-module and per-directory loglevel configuration.

1019N/A mod_ssl: Replace LogLevelDebugDump with trace log levels.
1019N/A mod_dumpio: Replace DumpIOLogLevel with trace log levels.
565N/A *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
565N/A title page only) when any mod_ldap directives were used in VirtualHost
565N/A context. [Eric Covener]
565N/A *) mod_disk_cache: Decline the opportunity to cache if the response is
565N/A a 206 Partial Content. This stops a reverse proxied partial response
565N/A from becoming cached, and then being served in subsequent responses.
565N/A *) mod_deflate: avoid the risk of forwarding data before headers are set.
565N/A *) mod_authnz_ldap: Ensure nested groups are checked when the
565N/A top-level group doesn't have any direct non-group members

565N/A can use the credentials from the authentication phase

565N/A server startup if no files or directories match a wildcard path.
838N/A *) htcacheclean: Report additional statistics about entries deleted.
838N/A *) Introduce SSLFIPS directive to support OpenSSL FIPS_mode; permits all
838N/A builds of mod_ssl to use 'SSLFIPS off' for portability, but the proper
565N/A build of openssl is required for 'SSLFIPS on'. PR 46270.

988N/A aborted the connection. In addition adjust the log message if the client
565N/A aborted the connection. [Ruediger Pluem]
922N/A *) mod_ssl: Add the 'SSLInsecureRenegotiation' directive, which
633N/A allows insecure renegotiation with clients which do not yet
616N/A support the secure renegotiation protocol. [Joe Orton]

838N/A *) mod_negotiation: Preserve query string over multiviews negotiation.
565N/A This buglet was fixed for type maps in 2.2.6, but the same issue
565N/A affected multiviews and was overlooked.
1050N/A *) mod_ldap: Eliminate a potential crash with multiple LDAPTrustedClientCert
1050N/A when some are not password-protected. [Eric Covener]
1050N/A *) Fix startup segfault when the Mutex directive is used but no loaded
1050N/A modules use httpd mutexes. PR 48787. [Jeff Trawick]
1050N/A *) Proxy: get the headers right in a HEAD request with
1050N/A ProxyErrorOverride, by checking for an overridden error

1050N/A *) mod_proxy_http: Make sure that when an ErrorDocument is served
1050N/A from a reverse proxied URL, that the subrequest respects the status
1050N/A of the original request. This brings the behaviour of proxy_handler
1050N/A in line with default_handler. PR 47106. [Graham Leggett]

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

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.
*) 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]

host-based access control provided by mod_authz_host and invoked
through the 'Require' directive. [Brad Nicholes]

seconds to cache a document.

Login/Session support [Nick Kew]
*) Fix typo in ProxyStatus syntax error message.
*) 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]
