  * ) SECURITY: CVE-2023-45802: Apache HTTP Server: HTTP/2 stream
    memory not reclaimed right away on RST (cve.mitre.org)
    When a HTTP/2 stream was reset (RST frame) by a client, there
    was a time window were the request's memory resources were not
    reclaimed immediately. Instead, de-allocation was deferred to
    connection close. A client could send new requests and resets,
    keeping the connection busy and open and causing the memory
    footprint to keep on growing. On connection close, all resources
    were reclaimed, but the process might run out of memory before
    that.
    This was found by the reporter during testing of CVE-2023-44487
    (HTTP/2 Rapid Reset Exploit) with their own test client. During
    "normal" HTTP/2 use, the probability to hit this bug is very
    low. The kept memory would not become noticeable before the
    connection closes or times out.
    Users are recommended to upgrade to version 2.4.58, which fixes
    the issue.

  * ) SECURITY: CVE-2023-43622: Apache HTTP Server: DoS in HTTP/2 with
    initial windows size 0 (cve.mitre.org)
    An attacker, opening a HTTP/2 connection with an initial window
    size of 0, was able to block handling of that connection
    indefinitely in Apache HTTP Server. This could be used to
    exhaust worker resources in the server, similar to the well
    known "slow loris" attack pattern.
    This has been fixed in version 2.4.58, so that such connection
    are terminated properly after the configured connection timeout.
    This issue affects Apache HTTP Server: from 2.4.55 through
    2.4.57.
    Users are recommended to upgrade to version 2.4.58, which fixes
    the issue.

    [Stefan Eissing]
  * ) mod_proxy_http2: improved error handling on connection errors while
    response is already underway.
    [Stefan Eissing]
  * ) mod_http2: fixed a bug that could lead to a crash in main connection
    output handling. This occured only when the last request on a HTTP/2
    connection had been processed and the session decided to shut down.
    This could lead to an attempt to send a final GOAWAY while the previous
    write was still in progress. See PR 66646.

  * ) mod_proxy_http2: fix `X-Forward-Host` header to carry the correct value.
    Fixes PR66752.
    [Stefan Eissing]
  * ) mod_http2: added support for bootstrapping WebSockets via HTTP/2, as
    described in RFC 8441. A new directive 'H2WebSockets on|off' has been
    added. The feature is by default not enabled.
    As also discussed in the manual, this feature should work for setups
    using "ProxyPass backend-url upgrade=websocket" without further changes.
    Special server modules for WebSockets will have to be adapted,
    most likely, as the handling if IO events is different with HTTP/2.
    HTTP/2 WebSockets are supported on platforms with native pipes. This
    excludes Windows.

    connection that could lead to a busy loop, preventing the HTTP/2 session
    to close down successfully. Fixed PR 66624.
    [Stefan Eissing]
  * ) mod_http2: v2.0.15 with the following fixes and improvements
  - New directive 'H2EarlyHint name value' to add headers to a response,
    picked up already when a "103 Early Hints" response is sent. 'name' and
    'value' must comply to the HTTP field restrictions.
    This directive can be repeated several times and header fields of the
    same names add. Sending a 'Link' header with 'preload' relation will
    also cause a HTTP/2 PUSH if enabled and supported by the client.
  - Fixed an issue where requests were not logged and accounted in a timely
    fashion when the connection returns to "keepalive" handling, e.g. when
    the request served was the last outstanding one.
    This led to late appearance in access logs with wrong duration times
    reported.
  - Accurately report the bytes sent for a request in the '%O' Log format.
    This addresses #203, a long outstanding issue where mod_h2 has reported
    numbers over-eagerly from internal buffering and not what has actually
    been placed on the connection.
    The numbers are now the same with and without H2CopyFiles enabled.

  * ) mod_proxy_http2: fix retry handling to not leak temporary errors.
    On detecting that that an existing connection was shutdown by the other
    side, a 503 response leaked even though the request was retried on a
    fresh connection.

  * ) mod_rewrite: Add server directory to include path as mod_rewrite requires
    test_char.h. PR 66571 [Valeria Petrov <valeria.petrov@spinetix.com>]
  * ) mod_http2: new directive `H2ProxyRequests on|off` to enable handling
    of HTTP/2 requests in a forward proxy configuration.
    General forward proxying is enabled via `ProxyRequests`. If the
    HTTP/2 protocol is also enabled for such a server/host, this new
    directive is needed in addition.

  * ) mod_http2: new directive 'H2MaxDataFrameLen n' to limit the maximum
    amount of response body bytes put into a single HTTP/2 DATA frame.
    Setting this to 0 places no limit (but the max size allowed by the
    protocol is observed).
    The module, by default, tries to use the maximum size possible, which is
    somewhat around 16KB. This sets the maximum. When less response data is
    available, smaller frames will be sent.

  * ) mod_http2: version 2.0.10 of the module, synchronizing changes
    with the gitgub version. This is a partial rewrite of how connections
    and streams are handled.
  - an APR pollset and pipes (where supported) are used to monitor
    the main connection and react to IO for request/response handling.
    This replaces the stuttered timed waits of earlier versions.
  - H2SerializeHeaders directive still exists, but has no longer an effect.
  - Clients that seemingly misbehave still get less resources allocated,
    but ongoing requests are no longer disrupted.
  - Fixed an issue since 1.15.24 that "Server" headers in proxied requests
    were overwritten instead of preserved. [PR by @daum3ns]
  - 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 #212.
  - Improved information displayed in 'server-status' for H2 connections when
    Extended Status is enabled. Now one can see the last request that IO
    operations happened on and transferred IO stats are updated as well.
  - 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 at
    <https://bz.apache.org/bugzilla/show_bug.cgi?id=65731>.
    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.
  - :scheme pseudo-header values, not matching the
    connection scheme, are forwarded via absolute uris to the
    http protocol processing to preserve semantics of the request.
    Checks on combinations of pseudo-headers values/absence
    have been added as described in RFC 7540. Fixes #230.
  - A bug that prevented trailers (e.g. HEADER frame at the end) to be
    generated in certain cases was fixed. See #233 where it prevented
    gRPC responses to be properly generated.
  - Request and response header values are automatically stripped of leading
    and trialing space/tab characters. This is equivalent behaviour to what
    Apache httpd's http/1.1 parser does.
    The checks for this in nghttp2 v1.50.0+ are disabled.
  - Extensive testing in production done by Alessandro Bianchi (@alexskynet)
    on the v2.0.x versions for stability. Many thanks!

    smuggling (cve.mitre.org)
    Inconsistent Interpretation of HTTP Requests ('HTTP Request
    Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server
    allows an attacker to smuggle requests to the AJP server it
    forwards requests to.  This issue affects Apache HTTP Server
    Apache HTTP Server 2.4 version 2.4.53 and prior versions.

    PR 65666.  [Yann Ylavic]
  * ) mod_md:  a bug was fixed that caused very large MDomains
    with the combined DNS names exceeding ~7k to fail, as
    request bodies would contain partially wrong data from
    uninitialized memory. This would have appeared as failure
    in signing-up/renewing such configurations.

  * ) mod_md: the `MDCertificateAuthority` directive can take more than one URL/name of
    an ACME CA. This gives a failover for renewals when several consecutive attempts
    to get a certificate failed.
    A new directive was added: `MDRetryDelay` sets the delay of retries.
    A new directive was added: `MDRetryFailover` sets the number of errored
    attempts before an alternate CA is selected for certificate renewals.

    ease identification of involved service.  [Rainer Jung]
  * ) mod_http2: removing unscheduling of ongoing tasks when
    connection shows potential abuse by a client. This proved
    counter-productive and the abuse detection can false flag
    requests using server-side-events.

    no shared memory slotmem was initialized.  [Rainer Jung]
  * ) mod_md: added support for managing certificates via a
    local tailscale daemon for users of that secure networking.
    This gives trusted certificates for tailscale assigned
    domain names in the *.ts.net space.

    relevant if no SSLProtocol is declared for the vhost or globally,
    otherwise the vhost or global value apply.  [Yann Ylavic]

  * ) mod_lua: Add r:headers_in_table, r:headers_out_table, r:err_headers_out_table,
    r:notes_table, r:subprocess_env_table as read-only native table alternatives
    that can be iterated over. [Eric Covener]

    r.headers_out, etc) to remove the key from the table. PR63971.
    [Eric Covener]
  * ) mod_http2: Fixed interaction with mod_reqtimeout. A loaded mod_http2 was disabling the
    ssl handshake timeouts. Also, fixed a mistake of the last version that made `H2Direct`
    always `on`, regardless of configuration. Found and reported by
    <Armin.Abfalterer@united-security-providers.ch> and
    <Marcial.Rion@united-security-providers.ch>. [Stefan Eissing]

  * ) mod_md v2.2.3:
  - Configuring MDCAChallenges replaces any previous existing challenge configuration. It
    had been additive before which was not the intended behaviour. [@mkauf]
  - Fixing order of ACME challenges used when nothing else configured. Code now behaves as
    documented for `MDCAChallenges`. Fixes #156. Thanks again to @mkauf for finding this.
  - Fixing a potential, low memory null pointer dereference [thanks to @uhliarik].
  - Fixing an incompatibility with a change in libcurl v7.66.0 that added unwanted
    "transfer-encoding" to POST requests. This failed in directy communication with
    Let's Encrypt boulder server. Thanks to @mkauf for finding and fixing. [Stefan Eissing]
  * ) mod_md: Adding the several new features.
    The module offers an implementation of OCSP Stapling that can replace fully or
    for a limited set of domains the existing one from mod_ssl. OCSP handling
    is part of mod_md's monitoring and message notifications. If can be used
    for sites that do not have ACME certificates.
    The url for a CTLog Monitor can be configured. It is used in the server-status
    to link to the external status page of a certicate.
    The MDMessageCmd is called with argument "installed" when a new certificate
    has been activated on server restart/reload. This allows for processing of
    the new certificate, for example to applications that require it in different
    locations or formats.

- require just libbrotli-devel

- build mod_proxy_http2 extension

- fix build for older distributions

- define DEFAULT_LISTENBACKLOG=APR_INT32_MAX. We want apache
  to honour net.core.somaxconn sysctl as the mandatory limit.
  the old value of 511 was never used as until v5.4-rc6 it was
  clamped to 128, in current kernels the default limit is 4096.
  Cannot use the apr_socket_listen(.., -1) idiom because the function
  expects a positive integer argument.
