Description Jonathan Steffan 2010-11-23 20:45:14 UTC
Spec URL: http://jsteffan.fedorapeople.org/SPECS/mod_remoteip.spec
SRPM URL: http://jsteffan.fedorapeople.org/SRPMS/mod_remoteip-0.1.20100929-1.fc13.src.rpm
Description: 
This module is used to treat the remote host which initiated the request as the
originating remote host as identified by httpd for the purposes of authorization
and logging, even where that remote host is behind a load balancer, front end
server, or proxy server.

The module replaces the apparent remote (client) IP/hostname for the request
with the IP address reported in the request header configured with the
RemoteIPHeader directive.

Once replaced as instructed, this apparent IP address is then used for
mod_authz_host features <Require host> and <Require ip>, is reported by
mod_status, and is recorded by mod_log_config a and h directives. It also
determines the machine probed for an inetd identity by mod_ident based on the
IdentityCheck configuration.

Comment 1 Jonathan Steffan 2010-11-23 20:47:01 UTC
As a note, this is only needed for branches with Apache 2.2.x as it's included with Apache 2.3 as a core module.

Comment 2 Robert Scheck 2011-06-05 17:17:56 UTC
Okay, here we go:

[ DONE ] MUST: rpmlint must be run on the source rpm and all binary rpms the 
         build produces. The output should be posted in the review.

$
[  OK  ] MUST: The package must be named according to the Package Naming 
         Guidelines.
[  OK  ] MUST: The spec file name must match the base package %{name}, in the 
         format %{name}.spec unless your package has an exemption.
[  ??  ] MUST: The package must meet the Packaging Guidelines.
[  OK  ] MUST: The package must be licensed with a Fedora approved license and 
         meet the Licensing Guidelines.
[  OK  ] MUST: The License field in the package spec file must match the actual 
         license.
[  N/A ] MUST: If (and only if) the source package includes the text of the 
         license(s) in its own file, then that file, containing the text of
         the license(s) for the package must be included in %doc.
[  OK  ] MUST: The spec file must be written in American English.
[  OK  ] MUST: The spec file for the package MUST be legible. 
[  OK  ] MUST: The sources used to build the package must match the upstream 
         source, as provided in the spec URL. Reviewers should use md5sum for 
         this task. If no upstream URL can be specified for this package, 
         please see the Source URL Guidelines for how to deal with this.
         -> e5266d44cf6ffc84bd4c855f71b2f4fb  mod_remoteip.c
         -> e5266d44cf6ffc84bd4c855f71b2f4fb  mod_remoteip.c.1
[  OK  ] MUST: The package MUST successfully compile and build into binary
         rpms on at least one primary architecture.
[  N/A ] MUST: If the package does not successfully compile, build or work on 
         an architecture, then those architectures should be listed in the
         spec in ExcludeArch. Each architecture listed in ExcludeArch MUST
         have a bug filed in bugzilla, describing the reason that the package 
         does not compile/build/work on that architecture. The bug number MUST 
         be placed in a comment, next to the corresponding ExcludeArch line.
[  OK  ] MUST: All build dependencies must be listed in BuildRequires, except 
         for any that are listed in the exceptions section of the Packaging 
         Guidelines; inclusion of those as BuildRequires is optional. Apply 
         common sense.
[  N/A ] MUST: The spec file MUST handle locales properly. This is done by 
         using the %find_lang macro. Using %{_datadir}/locale/* is strictly 
         forbidden.
[  N/A ] MUST: Every binary RPM package (or subpackage) which stores shared 
         library files (not just symlinks) in any of the dynamic linker's 
         default paths, must call ldconfig in %post and %postun.
[  OK  ] MUST: Packages must NOT bundle copies of system libraries.
[  N/A ] MUST: If the package is designed to be relocatable, the packager
         must state this fact in the request for review, along with the 
         rationalization for relocation of that specific package. Without
         this, use of Prefix: /usr is considered a blocker.
[  OK  ] MUST: A package must own all directories that it creates. If it does 
         not create a directory that it uses, then it should require a package 
         which does create that directory.
[  OK  ] MUST: A Fedora package must not list a file more than once in the
         spec file's %files listings. (Notable exception: license texts in 
         specific situations)
[  OK  ] MUST: Permissions on files must be set properly. Executables should
         be set with executable permissions, for example. Every %files section 
         must include a %defattr(...) line.
[  OK  ] MUST: Each package must consistently use macros.
         -> $RPM_BUILD_ROOT and %{buildroot} is used
[  OK  ] MUST: The package must contain code, or permissable content.
[  N/A ] MUST: Large documentation files must go in a -doc subpackage. (The 
         definition of large is left up to the packager's best judgement, but 
         is not restricted to size. Large can refer to either size or 
         quantity).
[  N/A ] MUST: If a package includes something as %doc, it must not affect
         the runtime of the application. To summarize: If it is in %doc, the 
         program must run properly if it is not present.
[  N/A ] MUST: Header files must be in a -devel package.
[  N/A ] MUST: Static libraries must be in a -static package.
[  N/A ] MUST: If a package contains library files with a suffix (e.g. 
         libfoo.so.1.1), then library files that end in .so (without suffix) 
         must go in a -devel package.
[  N/A ] MUST: In the vast majority of cases, devel packages must require the 
         base package using a fully versioned dependency: Requires: %{name}
         %{?_isa} = %{version}-%{release}
[  N/A ] MUST: Packages must NOT contain any .la libtool archives, these must 
         be removed in the spec if they are built.
[  N/A ] MUST: Packages containing GUI applications must include a 
         %{name}.desktop file, and that file must be properly installed with 
         desktop-file-install in the %install section. If you feel that your 
         packaged GUI application does not need a .desktop file, you must put
         a comment in the spec file with your explanation.
[  OK  ] MUST: Packages must not own files or directories already owned by 
         other packages. The rule of thumb here is that the first package to
         be installed should own the files or directories that other packages 
         may rely upon. This means, for example, that no package in Fedora 
         should ever share ownership with any of the files or directories
         owned by the filesystem or man package. If you feel that you have a 
         good reason to own a file or directory that another package owns,
         then please present that at package review time.
[  OK  ] MUST: All filenames in rpm packages must be valid UTF-8. 


[  N/A ] SHOULD: If the source package does not include license text(s) as a 
         separate file from upstream, the packager SHOULD query upstream to 
         include it.
[  OK  ] SHOULD: The description and summary sections in the package spec file 
         should contain translations for supported Non-English languages, if 
         available.
[  OK  ] SHOULD: The reviewer should test that the package builds in mock.
[  OK  ] SHOULD: The package should compile and build into binary rpms on all 
         supported architectures.
[ SKIP ] SHOULD: The reviewer should test that the package functions as 
         described. A package should not segfault instead of running, for 
         example.
[  N/A ] SHOULD: If scriptlets are used, those scriptlets must be sane. This
         is vague, and left up to the reviewers judgement to determine sanity. 
[  N/A ] SHOULD: Usually, subpackages other than devel should require the base 
         package using a fully versioned dependency.
[  N/A ] SHOULD: The placement of pkgconfig(.pc) files depends on their 
         usecase, and this is usually for development purposes, so should be 
         placed in a -devel pkg. A reasonable exception is that the main pkg 
         itself is a devel tool not installed in a user runtime, e.g. gcc or 
         gdb.
[  N/A ] SHOULD: If the package has file dependencies outside of /etc, /bin,
         /sbin, /usr/bin, or /usr/sbin consider requiring the package which 
         provides the file instead of the file itself.
[  N/A ] SHOULD: your package should contain man pages for binaries/scripts.
         If it doesn't, work with upstream to add them where they make sense.


Further things (mixed, must and should):
- "unstripped-binary-or-object" can (and must) be solved by putting the 
  forgotten/missing line "%setup -q -T -c" after line "%prep".
- Summary "Apache Module mod_remoteip" doesn't say anything. Example for a
  proper summary is "Apache module to replace client IP/hostname with that 
  given by a proxy", however something better than now is a must.
- May you explain where you get the version number from? I was not able to
  find a version number anywhere. If unsure use "Version: 0" rather current
  "Version: 0.1.20100929". A correct version/release tag is a must.
- If you want to mention a date from a checkout or similar, please note that
  it needs to be specified in release tag and by mentioning the type of SCM.
- Recommented to replace "%defattr (-,root,root)" by "%defattr(-,root,root,-)"
- Are you sure that /etc/httpd/conf.d/mod_remoteip.conf is really correct
  and not /etc/httpd/conf.d/remoteip.conf, like most other Apache modules are
  using? IMHO there is no need for mod_* in the configuration file name.
- Why is the configuration file mentioned previously inline? If somebody is
  configuring that module using your default configuration file and if you
  are performing a rebuild of the package or a dist-upgrade takes place, rpm
  will generate a .rpm(new|old|save) file - even if your default file did not
  change but the timestamp of your packaged file is newer, because it is
  created during build. I highly recommend here to put the configuration file
  default into a separate source file, e.g. "Source1: remoteip.conf".
- Replace "install %{SOURCE0} ." by "install -m 644 %{SOURCE0} ." or even by
  a "cp -pf %{SOURCE0} ." to avoid unnecessary "spurious-executable-perm" 
  warning in -debuginfo subpackage that will show up once first issue in this
  list is solved.
- Is "Requires: httpd >= 2.2, httpd < 2.3" really needed? If yes, I would
  like to get explained why. From my point of view, the ABI compatibility
  is guaranteed via httpd-mmn requirement and 2.3 should have another value
  for that field, shouldn't it? Keeping the restriction for buildrequires is
  nevertheless okay from my point of view.

Okay...that's it for now.

Comment 3 Robert Scheck 2011-07-10 11:08:38 UTC
Ping? Still interested?

Comment 4 Ken Dreyer 2012-05-03 23:51:15 UTC
I've been meaning to look into packaging this module for EPEL 6. Jonathan, still interested?

Comment 5 Steve Cleveland 2012-06-05 21:17:34 UTC
I would be very much interested in this package.  We have a lot of sites that rely on IP-based access controls and I'm looking to setup a load balancer.  We won't be ready for Apache 2.4 for a long time yet, so this module would be a tremendous help.  I'm also available to test it.

Comment 6 Robert Scheck 2012-06-05 23:20:34 UTC
Jonathan, are you still interested in getting this package into Fedora?

Comment 7 Jonathan Steffan 2012-11-25 05:04:48 UTC
Yes. I will work on updates to the spec tomorrow and submit a new revision to address the concerns.

Comment 10 Jonathan Steffan 2012-11-25 22:04:27 UTC
Robert,

Are you still interested in doing this review? As we are getting httpd 2.4 in f18+ this is not as critical for Fedora but I'll doing builds for f16, f17, el5 and el6 as they will remain httpd 2.2.

Thanks for your review.

Comment 11 Ken Dreyer 2012-12-27 08:22:28 UTC
Fifteen packages in Fedora 17 have a httpd configuration file that begins with "mod_" so there is certainly precedent for keeping the "mod_" prefix in the name.

Comment 12 Robert Scheck 2012-12-27 09:02:38 UTC
Ken, I disagree. The package is intended for EPEL only as per description. I
will try to do the package review these days. Sorry for the delay.

Comment 13 Ken Dreyer 2012-12-27 16:05:36 UTC
(In reply to comment #12)
> Ken, I disagree. The package is intended for EPEL only as per description. I

Respectfully I disagree as well. As Comment 10 indicates, F17 still ships httpd 2.2. Additionally the EL+EPEL repos still contain eight (el5) and seven (el6) unique packages that fit the "mod_" convention. There's also something to be said for keeping in line with upstream, since they ship a "mod_remoteip.conf" file.

Comment 14 Robert Scheck 2012-12-27 17:18:17 UTC
I finally don't get your issue. I am fine with /etc/httpd/conf.d/remoteip.conf
as long as it's on a branch having Apache < 2.3. That is at least how IMHO most
of the separate Apache modules are packaged or were packaged for years now. And
if the packager wants /etc/httpd/conf.d/mod_remoteip.conf while Apache < 2.3,
it is also fine to me. I can not detect anything conflicting in the packaging draft: http://fedoraproject.org/wiki/PackagingDrafts/ApacheHTTPModules

I'm fine with either mod_remoteip.conf or remoteip.conf. My preference is mod_remoteip.conf but it's a simple change to make it remoteip.conf in %install.

I'm also fine with adding a Conflicts: httpd >= 2.3 if that will enforce for you I will not be building for anything greater then httpd 2.2.

Comment 17 pada 2013-02-07 14:43:24 UTC
By the way, I've disabled IPv6 on the affected machine:

# grep IPV6 /etc/sysconfig/network
NETWORKING_IPV6=no

# cat /etc/modprobe.d/local.conf 
install net-pf-10 /bin/true
blacklist net-pf-10
install ipv6 /bin/true
blacklist ipv6

Comment 18 Stefan Neufeind 2016-08-12 06:02:34 UTC
This neither affects Fedora anymore nor RHEL 7 since they both ship with newer httpd which includes mod_remoteip. Close this issue?

Comment 19 pada 2016-08-21 22:18:21 UTC
We have switched to RHEL 7 which includes httpd 2.4 and mod_remoteip, so I vote for closing this issue.
