Changes with Apache 2.4.29
*) mod_unique_id: Use output of the PRNG rather than IP address and
pid, avoiding sleep() call and possible DNS issues at startup,
plus improving randomness for IPv6-only hosts.
*) mod_rewrite, core: Avoid the 'Vary: Host' response header when HTTP_HOST
is used in a condition that evaluates to true.
*) mod_http2: v0.10.12, removed optimization for mutex handling in bucket
beams that could lead to assertion failure in edge cases.
*) mod_proxy: Fix regression for non decimal loadfactor parameter introduced
in 2.4.28.
*) mod_authz_dbd: fix a segmentation fault if AuthzDBDQuery is not set.
*) mod_rewrite: Add support for starting External Rewriting Programs
as non-root user on UNIX systems by specifying username and group
name as third argument of RewriteMap directive.
*) core: Rewrite the Content-Length filter to avoid excessive memory
consumption. Chunked responses will be generated in more cases
than in previous releases.
*) mod_ssl: Fix SessionTicket callback return value, which does seem to
matter with OpenSSL 1.1.
Changes with Apache 2.4.28
*) SECURITY: CVE-2017-9798 (cve.mitre.org)
Corrupted or freed memory access. <Limit[Except]> must now be used in the
main configuration file (httpd.conf) to register HTTP methods before the
.htaccess files.
*) event: Avoid possible blocking in the listener thread when shutting down
connections.
*) mod_speling: Don't embed referer data in a link in error page.
*) htdigest: prevent a buffer overflow when a string exceeds the allowed max
length in a password file.
*) mod_proxy: loadfactor parameter can now be a decimal number (eg: 1.25).
*) mod_proxy_wstunnel: Allow upgrade to any protocol dynamically.
*) mod_watchdog/mod_proxy_hcheck: Time intervals can now be spefified
down to the millisecond. Supports 'mi' (minute), 'ms' (millisecond),
's' (second) and 'hr' (hour!) time suffixes.
*) mod_http2: Fix for stalling when more than 32KB are written to a
suspended stream.
*) build: allow configuration without APR sources.
*) mod_ssl, ab: Fix compatibility with LibreSSL.
*) core/log: Support use of optional "tag" in syslog entries.
*) mod_proxy: Fix ProxyAddHeaders merging.
*) core: Disallow multiple Listen on the same IP:port when listener buckets
are configured (ListenCoresBucketsRatio > 0), consistently with the single
bucket case (default), thus avoiding the leak of the corresponding socket
descriptors on graceful restart.
*) event: Avoid listener periodic wake ups by using the pollset wake-ability
when available.
*) mod_proxy_wstunnel: Fix detection of unresponded request which could have
led to spurious HTTP 502 error messages sent on upgrade connections.
*) COMPATIBILITY: mod_lua: Remove the undocumented exported 'apr_table'
global variable when using Lua 5.2 or later. This was exported as a
side effect from luaL_register, which is no longer supported as of
Lua 5.2 which deprecates pollution of the global namespace.
*) COMPATIBILITY: mod_http2: Disable and give warning when using Prefork.
The server will continue to run, but HTTP/2 will no longer be negotiated.
*) COMPATIBILITY: mod_proxy_fcgi: Revert to 2.4.20 FCGI behavior for the
default ProxyFCGIBackendType, fixing a regression with PHP-FPM.
*) mod_lua: Improve compatibility with Lua 5.1, 5.2 and 5.3.
*) mod_http2: Simplify ready queue, less memory and better performance. Update
mod_http2 version to 1.10.7.
*) Allow single-char field names inadvertently disallowed in 2.4.25.
*) htpasswd / htdigest: Do not apply the strict permissions of the temporary
passwd file to a possibly existing passwd file.
*) core: Avoid duplicate HEAD in Allow header.
This is a regression in 2.4.24 (unreleased), 2.4.25 and 2.4.26.
*) HTTP/2 support no longer tagged as "experimental" but is instead considered
fully production ready.
*) mod_http2: Fix for possible CPU busy loop introduced in v1.10.3 where a stream may keep
the session in continuous check for state changes that never happen.
*) mod_mime: Fix error checking for quoted pairs.
*) mod_proxy_wstunnel: Add "upgrade" parameter to allow upgrade to other
protocols.
*) MPMs unix: Place signals handlers and helpers out of DSOs to avoid
a possible crash if a signal is caught during (graceful) restart.
*) core: Deprecate ap_get_basic_auth_pw() and add
ap_get_basic_auth_components().
*) mod_rewrite: When a substitution is a fully qualified URL, and the
scheme/host/port matches the current virtual host, stop interpreting the
path component as a local path just because the first component of the
path exists in the filesystem. Adds RewriteOption "LegacyPrefixDocRoot"
to revert to previous behavior.
*) core: ap_parse_form_data() URL-decoding doesn't work on EBCDIC
platforms.
*) ab: enable option processing for setting a custom HTTP method also for
non-SSL builds.
*) core: EBCDIC fixes for interim responses with additional headers.
*) mod_ssl: Consistently pass the expected bio_filter_in_ctx_t
to ssl_io_filter_error().
*) mod_env: when processing a 'SetEnv' directive, warn if the environment
variable name includes a '='. It is likely a configuration error.
*) Evaluate nested If/ElseIf/Else configuration blocks.
*) mod_rewrite: Add 'BNP' (backreferences-no-plus) flag to RewriteRule to
allow spaces in backreferences to be encoded as %20 instead of '+'.
*) mod_rewrite: Add the possibility to limit the escaping to specific
characters in backreferences by listing them in the B flag.
*) mod_substitute: Fix spurious AH01328 (Line too long) errors on EBCDIC
systems.
*) mod_http2: fail requests without ERROR log in case we need to read interim
responses and see only garbage. This can happen if proxied servers send
data where none should be, e.g. a body for a HEAD request.

This release fixes several security problems, some of them are already
handled in pkgsrc. Please refer CHANGES file in detail.
*) SECURITY: CVE-2016-8740 (cve.mitre.org)
mod_http2: Mitigate DoS memory exhaustion via endless
CONTINUATION frames.
[Naveen Tiwari <naveen.tiwari@asu.edu> and CDF/SEFCOM at Arizona State
University, Stefan Eissing]
*) SECURITY: CVE-2016-5387 (cve.mitre.org)
core: Mitigate [f]cgi "httpoxy" issues.
[Dominic Scheirlinck <dominic vendhq.com>, Yann Ylavic]
*) SECURITY: CVE-2016-2161 (cve.mitre.org)
mod_auth_digest: Prevent segfaults during client entry allocation when
the shared memory space is exhausted.
[Maksim Malyutin <m.malyutin dsec.ru>, Eric Covener, Jacob Champion]
*) SECURITY: CVE-2016-0736 (cve.mitre.org)
mod_session_crypto: Authenticate the session data/cookie with a
MAC (SipHash) to prevent deciphering or tampering with a padding
oracle attack. [Yann Ylavic, Colm MacCarthaigh]
*) SECURITY: CVE-2016-8743 (cve.mitre.org)
Enforce HTTP request grammar corresponding to RFC7230 for request lines
and request headers, to prevent response splitting and cache pollution by
malicious clients or downstream proxies. [William Rowe, Stefan Fritsch]
(NOTE: Versions 2.4.22 and 2.4.21 were not released.)
Changes from 2.4.20 are too many to write here, please refer CHANGES file.
And Apache 2.4.23 fixes CVE-2016-4979; X509 Client certificate based
authentication can be bypassed when HTTP/2 is used.
When updating this package, make sure that no strings like
"PR 12345" are in the commit message. Upstream likes
to reference their own PRs this way, but this ends up
in NetBSD GNATS.
*) core: Do not read .htaccess if AllowOverride and AllowOverrideList
are "None". PR 58528.
*) mod_proxy_express: Fix possible use of DB handle after close. PR 59230.
*) core/util_script: relax alphanumeric filter of enviroment variable names
on Windows to allow '(' and ')' for passing PROGRAMFILES(X86) et.al.
unadulterated in 64 bit versions of Windows. PR 46751.
*) mod_http2: incrementing keepalives on each request started so that logging
%k gives increasing numbers per master http2 connection.
New documented variables in env, usable in custom log formats: H2_PUSH,
H2_PUSHED, H2_PUSHED_ON, H2_STREAM_ID and H2_STREAM_TAG.
*) mod_http2: more efficient passing of response bodies with less contention
and file bucket forwarding.
*) mod_http2: fix for missing score board updates on request count, fix for
memory leak on slave connection reuse.
*) mod_http2: Fix build on Windows from dsp files.
This goes as far back as 2001 (mk.conf.example) but there should not be any
reason to explicitly set CFLAGS for specific packages. In practice this
even fixes support for global CFLAGS in www/apache{22,24}.
ok gdt@
*) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
if conn_rec itself holds no valid SSLConnRec*. Fixes 58666.
*) mod_http2: connection level window for flow control is set to protocol
maximum of 2GB-1, preventing window exhaustion when sending data on many
streams with higher cumulative window size.
Reducing write frequency unless push promises need to be flushed.
*) mod_http2: required minimum version of libnghttp2 is 1.2.1
*) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
In earlier version of httpd, you can explicitelly set the 'flusher' parameter
to 'flush' as a workaround. (i.e. flusher=flush)
Add documentation for the 'flusher' parameter when defining a proxy worker.
*) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
to only staple responses with certificate status "good".
*) mod_http2: new directive 'H2PushPriority' to allow priority specifications
on server pushed streams according to their content-type.
*) mod_http2: fixes crash on connection abort for a busy connection.
fixes crash on a request that did not produce any response.
*) mod_http2: trailers are sent after reponse body if set in request_rec
trailers_out before the end-of-request bucket is sent through the
output filters.
*) mod_http2: incoming trailers (headers after request body) are properly
forwarded to the processing engine.
*) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
pushes a server/virtual host. Pushes are initiated by the presence
of 'Link:' headers with relation 'preload' on a response.
*) mod_http2: write performance of http2 improved for larger resources,
especially static files.
*) core: if the first HTTP/1.1 request on a connection goes to a server that
prefers different protocols, these protocols are announced in a Upgrade:
header on the response, mentioning the preferred protocols.
*) mod_http2: new directives 'H2TLSWarmUpSize' and 'H2TLSCoolDownSecs'
to control TLS record sizes during connection lifetime.
*) mod_http2: new directive 'H2ModernTLSOnly' to enforce security
requirements of RFC 7540 on TLS connections.
*) core: add ap_get_protocol_upgrades() to retrieve the list of protocols
that a client could possibly upgrade to. Use in first request on a
connection to announce protocol choices.
*) mod_http2: reworked deallocation on connection shutdown and worker
abort. Separate parent pool for all workers. worker threads are joined
on planned worker shutdown.
*) 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
match.
Renegotiation is 403ed when a master connection is present. Exact reason
is given additionally in a request note.
*) core: Fix scoreboard crash (SIGBUS) on hardware requiring strict 64bit
alignment (SPARC64, PPC64).
*) mod_cache: Accept HT (Horizontal Tab) when parsing cache related header
fields as described in RFC7230.
*) core/util_script: making REDIRECT_URL a full URL is now opt-in
via new 'QualifyRedirectURL' directive.
*) core: Limit to ten the number of tolerated empty lines between request,
and consume them before the pipelining check to avoid possible response
delay when reading the next request without flushing.
*) mod_ssl: Extend expression parser registration to support ssl variables
in any expression using mod_rewrite syntax "%{SSL:VARNAME}" or function
syntax "ssl(VARNAME)".
The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
*) mod_http2: added donated HTTP/2 implementation via core module. Similar
configuration options to mod_ssl.
*) mod_proxy: don't recyle backend announced "Connection: close" connections
to avoid reusing it should the close be effective after some new request
is ready to be sent.
*) mod_substitute: Allow to configure the patterns merge order with the new
SubstituteInheritBefore on|off directive.
*) mod_proxy: Fix ProxySourceAddress binding failure with AH00938.
*) mod_ssl: Support compilation against libssl built with OPENSSL_NO_SSL3,
and change the compiled-in default for SSL[Proxy]Protocol to "all -SSLv3",
in accordance with RFC 7568.
*) mod_ssl: append :!aNULL:!eNULL:!EXP to the cipher string settings,
instead of prepending !aNULL:!eNULL:!EXP: (as was the case in 2.4.7
and later). Enables support for configuring the SUITEB* cipher
strings introduced in OpenSSL 1.0.2.
*) mod_ssl: Add support for extracting the msUPN and dnsSRV forms
of subjectAltName entries of type "otherName" into
SSL_{CLIENT,SERVER}_SAN_OTHER_{msUPN,dnsSRV}_n environment
variables.
*) mod_logio: Fix logging of %^FB (time to first byte) on the first request on
an SSL connection.
*) mod_cache: r->err_headers_out is not merged into
r->headers when mod_cache is enabled and the response
is cached for the first time.
*) mod_slotmem_shm: Fix slots/SHM files names on restart for systems that
can't create new (clear) slots while previous children gracefully stopping
still use the old ones (e.g. Windows, OS2). mod_proxy_balancer failed to
restart whenever the number of configured balancers/members changed during
restart.
*) core/util_script: make REDIRECT_URL a full URL.
*) MPMs: Support SO_REUSEPORT to create multiple duplicated listener
records for scalability.
*) mod_proxy: Fix a race condition that caused a failed worker to be retried
before the retry period is over.
*) mod_autoindex: Allow autoindexes when neither mod_dir nor mod_mime are
loaded.
*) mod_rewrite: Allow cookies set by mod_rewrite to contain ':' by accepting
';' as an alternate separator.
*) apxs: Add HTTPD_VERSION and HTTPD_MMN to the variables available with
apxs -q.
*) mod_rewrite: Avoid a crash when lacking correct DB access permissions
when using RewriteMap with MapType dbd or fastdbd.
*) mod_authz_dbd: Avoid a crash when lacking correct DB access permissions.
*) mod_socache_memcache: Add the 'MemcacheConnTTL' directive to control how
long to keep idle connections with the memcache server(s).
Change default value from 600 usec (!) to 15 sec.
*) mod_dir: Prevent the internal identifier "httpd/unix-directory" from
appearing as a Content-Type response header when requests for a directory
are rewritten by mod_rewrite.

- mod_lua: Disallow newlines in table values inside the request_rec,
to prevent HTTP Response Splitting via tainted headers.
[Daniel Gruno, Felipe Daragon <filipe syhunt com>]
- mod_lua: Remove the non-working early/late arguments for
LuaHookCheckUserID. [Daniel Gruno]
- mod_lua: Change IVM storage to use shm [Daniel Gruno]
- mod_lua: More verbose error logging when a handler function cannot be
found. [Daniel Gruno]
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
*) mod_ssl: Work around a bug in some older versions of OpenSSL that
would cause a crash in SSL_get_certificate for servers where the
certificate hadn't been sent.
*) mod_lua: Add a fixups hook that checks if the original request is intended
for LuaMapHandler. This fixes a bug where FallbackResource invalidates the
LuaMapHandler directive in certain cases by changing the URI before the map
handler code executes
Changes 2.4.8:
*) SECURITY: CVE-2014-0098 (cve.mitre.org)
Clean up cookie logging with fewer redundant string parsing passes.
Log only cookies with a value assignment. Prevents segfaults when
logging truncated cookies.
*) SECURITY: CVE-2013-6438 (cve.mitre.org)
mod_dav: Keep track of length of cdata properly when removing
leading spaces. Eliminates a potential denial of service from
specifically crafted DAV WRITE requests
*) core: Support named groups and backreferences within the LocationMatch,
DirectoryMatch, FilesMatch and ProxyMatch directives. (Requires
non-ancient PCRE library)
*) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
TE/CL conflicts.
*) mod_dir: Add DirectoryCheckHandler to allow a 2.2-like behavior, skipping
execution when a handler is already set.
*) mod_ssl: Do not perform SNI / Host header comparison in case of a
forward proxy request.
*) mod_ssl: Remove the hardcoded algorithm-type dependency for the
SSLCertificateFile and SSLCertificateKeyFile directives, to enable
future algorithm agility, and deprecate the SSLCertificateChainFile
directive (obsoleted by SSLCertificateFile).
*) mod_rewrite: Add RewriteOptions InheritDown, InheritDownBefore,
and IgnoreInherit to allow RewriteRules to be pushed from parent scopes
to child scopes without explicitly configuring each child scope.
*) prefork: Fix long delays when doing a graceful restart.
*) FreeBSD: Disable IPv4-mapped listening sockets by default for versions
5+ instead of just for FreeBSD 5.
*) mod_proxy_wstunnel: Avoid busy loop on client errors, drop message
IDs 02445, 02446, and 02448 to TRACE1 from DEBUG.
*) mod_remoteip: Correct the trusted proxy match test.
*) mod_proxy_fcgi: Fix error message when an unexpected protocol version
number is received from the application.
*) mod_remoteip: Use the correct IP addresses to populate the proxy_ips field.
*) mod_lua: Update r:setcookie() to accept a table of options and add domain,
path and httponly to the list of options available to set.
*) mod_lua: Fix r:setcookie() to add, rather than replace,
the Set-Cookie header.
*) mod_lua: Allow for database results to be returned as a hash with
row-name/value pairs instead of just row-number/value.
*) mod_rewrite: Add %{CONN_REMOTE_ADDR} as the non-useragent counterpart to
%{REMOTE_ADDR}.
*) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
save the socket for reuse by the next worker as if it were an
APR_SO_DISCONNECTED socket. Restores 2.2 behavior.
*) mod_dir: Don't search for a DirectoryIndex or DirectorySlash on a URL
that was just rewritten by mod_rewrite.
*) mod_session: When we have a session we were unable to decode,
behave as if there was no session at all.
*) mod_session: Fix problems interpreting the SessionInclude and
SessionExclude configuration.
*) mod_authn_core: Allow <AuthnProviderAlias>'es to be seen from auth
stanzas under virtual hosts.
*) mod_proxy_fcgi: Use apr_socket_timeout_get instead of hard-coded
30 seconds timeout.
*) mod_proxy: Added support for unix domain sockets as the
backend server endpoint
*) build: only search for modules (config*.m4) in known subdirectories, see
build/config-stubs.
*) mod_cache_disk: Fix potential hangs on Windows when using mod_cache_disk.
*) mod_ssl: Add support for OpenSSL configuration commands by introducing
the SSLOpenSSLConfCmd directive.
*) mod_proxy: Remove (never documented) <Proxy ~ wildcard-url> syntax which
is equivalent to <ProxyMatch wildcard-url>.
*) mod_authz_user, mod_authz_host, mod_authz_groupfile, mod_authz_dbm,
mod_authz_dbd, mod_authnz_ldap: Support the expression parser within the
require directives.
*) mod_proxy_http: Core dumped under high load.
*) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
previously limited to 64MB.
*) mod_lua: Use binary copy when dealing with uploads through r:parsebody()
to prevent truncating files.
