Topic: Apache 2.2.1

[Steffen]

I have build Apache 2.2.1 based on the ASF source.

It looks like that ASF is not releasing 2.2.1, because they have choosen to builde it against APR 1.2.6 and there are some (minor)issues with. And they are considering to skip Apache 2 .2.1

I build it against APR 1.3.0 and it works fine here.

Apache 2.2.1 has quite some fixes, special in the Proxy area, see changelist log below.

Give it a try and please inform me if all goes well, so I can announce it "official" here.

Changelog:

Changes with Apache 2.2.1

*) SECURITY: CVE-2005-3357 (cve.mitre.org)
mod_ssl: Fix a possible crash during access control checks if a
non-SSL request is processed for an SSL vhost (such as the
"HTTP request received on SSL port" error message when an 400
ErrorDocument is configured, or if using "SSLEngine optional").
PR 37791. [Rüdiger Plüm, Joe Orton]

*) SECURITY: CVE-2005-3352 (cve.mitre.org)
mod_imagemap: Escape untrusted referer header before outputting
in HTML to avoid potential cross-site scripting. Change also
made to ap_escape_html so we escape quotes. Reported by JPCERT.
[Mark Cox]

*) mod_proxy_ajp: Flushing of the output after each AJP chunk is now
configurable at runtime via the 'flushpackets' and 'flushwait' worker
params. Minor MMN bump. [Jim Jagielski]

*) mod_proxy: Fix incorrect usage of local and shared worker init.
PR 38403. [Jim Jagielski]

*) mod_isapi: Fix compiler errors on Unix platforms.
[William Rowe]

*) mod_proxy_http: Do send keep-alive header if the client sent
connection: keep-alive and do not close backend connection if the client
sent connection: close. PR 38524. [Ruediger Pluem, Joe Orton]

*) mod_disk_cache: Return the correct error codes from bucket read
failures, instead of APR_EGENERAL.
[Brian Akins <brian.akins turner.com>]

*) Add APR/APR-Util Compiled and Runtime Version numbers to the
output of 'httpd -V'. [William Rowe]

*) http: If a connection is aborted while waiting for a chunked line,
flag the connection as errored out. [Justin Erenkrantz]

*) core: Reject invalid Expect header immediately. PR 38123.
[Ruediger Pluem]

*) Fix mis-shifted 32 bit scope, masked to 64 bits as a method.
[Will Rowe, Joe Orton]

*) mod_proxy: Fix KeepAlives not being allowed and set to
backend servers. PR 38602. [Ruediger Pluem, Jim Jagielski]

*) Fix instdso.sh "sed syntax error" installation issue on some
platforms. PR 38108. [Masaoki Kobayashi <masaoki techfirm.co.jp>]

*) mod_ssl: Fix possible crashes in shmcb with gcc 4 on platforms
requiring word-aligned pointers. PR 38838. [Joe Orton]

*) mod_proxy: If we get an error reading the upstream response,
close the connection. [Justin Erenkrantz, Roy T. Fielding,
Jim Jagielski, Ruediger Pluem]

*) mod_proxy_ajp: Support common headers of the AJP protocol in responses.
PR 38340. [Aleksey Pesternikov <apesternikov yahoo.com>]

*) mod_proxy_balancer: Do not overwrite the status of initialized workers and
respect the configured status of uninitilized workers when creating a new
child process. [Ruediger Pluem]

*) mod_proxy_ajp: Crosscheck the length of the body chunk with the length of
the ajp message to prevent mod_proxy_ajp from reading beyond the buffer
boundaries and thus revealing possibly sensitive memory contents to the
client. [Ruediger Pluem]

*) Ensure that the proper status line is written to the client, fixing
incorrect status lines caused by filters which modify r->status without
resetting r->status_line, such as the built-in byterange filter.
[Jeff Trawick]

*) mod_speling: Stop crashing with certain non-file requests. [Jeff Trawick]

*) mod_cache: Make caching of reverse proxies possible again. PR 38017.
[Ruediger Pluem]

*) Modify apr[util] .h detection to avoid breakage on VPATH builds
using Solaris make (amoung others) and avoid breakage in ./buildconf
when srclib/apr[-util] are symlinks rather than directories proper.
[William Rowe]

*) Avoid Server-driven negotiation when a script has emitted an
explicit Status: header. PR 38070. [Nick Kew]

*) Fix to avoid feeding C99 to C++ compilers. [Joe Orton]

*) Chunk filter: Fix chunk filter to create correct chunks in the case that
a flush bucket is surrounded by data buckets. [Ruediger Pluem]

*) Fix syntax error in httpd.h with strict compilers. PR 37840.
[Per Olausson <pao darkheim.freeserve.co.uk>]

*) Fix recursive ErrorDocument handling. PR 36090.
[Chris Darroch <chrisd pearsoncmg.com>]

*) Don't hang on error return from post_read_request. PR 37790.
[Nick Kew]

*) Fix off-by-one error in proxy_balancer. PR 37753.

Note:
The modules on the download page here are working fine with 2.2.1, there is no need to rebuild them against 2.2.1.
