The HTTP/2 protocol allows a denial of service (server resource consumption)
because request cancellation can reset many streams quickly,
as exploited in the wild in August through October 2023.

if we run opkg install nginx on our system (without systemd)
we end up getting the following message in the install process
$ opkg install nginx_1.20.1-r0_core2-64.ipk
...
//var/lib/opkg/info/nginx.postinst: line 3: type: systemd-tmpfiles: not found
this confused some of my coworkers.
as installation also finishes correctly without sytemd-tmpfiles

Changelog:
==========
*) 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
vulnerabilty 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.
*) OpenSSL autoconf detection improvement: pick up openssl.pc in the
specified openssl path.
*) mod_proxy_connect, mod_proxy: Do not change the status code after we
already sent it to the client.
*) 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
*) 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().
*) 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.
*) mpm_event: Restart stopping of idle children after a load peak. PR 65626.
*) 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>.
*) mod_ssl: Add build support for OpenSSL v3.
*) mod_proxy_connect: Honor the smallest of the backend or client timeout
while tunneling.
*) mod_proxy: SetEnv proxy-nohalfclose (or alike) allows to disable TCP
half-close forwarding when tunneling protocols.
*) core: Be safe with ap_lingering_close() called with a socket NULL-ed by
a third-party module. PR 65627.
*) mod_md: Fix memory leak in case of failures to load the private key.
PR 65620
*) 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 repsonse 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.
*) mod_proxy_uwsgi: Remove duplicate slashes at the beginning of PATH_INFO.

mod_http2: Request splitting vulnerability with mod_proxy [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`.

*) mod_ssl: Support logging private key material for use with
wireshark via log file given by SSLKEYLOGFILE environment
variable. Requires OpenSSL 1.1.1. PR 63391. [Joe Orton]

[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 accomodates 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.

- mod_forensic: Follow up to r1856490: missing one mod_log_forensic test_char_table case.
- mod_rewrite: Save a few cycles.
- mod_request: Fix a comment (missing '_' in 'keep_body') and some style issues
- core: remove extra whitespace in HTTP_NOT_IMPLEMENTED
[Christophe Jaillet]
*) core/mpm: add hook 'child_stopping` that gets called when the MPM is
stopping a child process. The additional `graceful` parameter allows
registered hooks to free resources early during a graceful shutdown.
[Yann Ylavic, Stefan Eissing]
*) mod_proxy: Fix icomplete initialization of BalancerMember(s) from the
balancer-manager, which can lead to a crash. [Yann Ylavic]
*) mpm_event: Fix graceful stop/restart of children processes if connections
are in lingering close for too long. [Yann Ylavic]
*) mod_md: fixed a potential null pointer dereference if ACME/OCSP
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.
