Bug#1023881: Buster: oldstable: apache2-bin: mod_cgid: No socket created for cgid at /var/run/apache2

[Sebastian Kraus <sebastian.kraus@tu-berlin.de>]

Package: apache2-bin
Version: 2.4.38-3+deb10u8
Arch: amd64
Severity: important
Tags: buster


Dear maintainers,

the bug is about apache2-bin in oldstable. The cgid module of apache2 fails to install/open the necessary socket at /var/run/apache2/. On startup, the Apache httpd does not care about creating this socket. The error log of Apache httpd presents you things like:

[Sat Nov 12 01:55:17.617778 2022] [cgid:error] [pid 10238:tid 139931184354432] (1)Operation not permitted: AH01246: Couldn't change owner of unix domain socket /var/run/apache2/cgisock.10234

[Sat Nov 12 01:56:37.912856 2022] [cgid:error] [pid 10240:tid 139931155764992] (2)No such file or directory: [client 127.0.0.1:39024] AH02833: ScriptSock /var/run/apache2/cgisock.10234 does not exist: /var/www/html/test.cgi


Please test yourself with:

1) a2enmod cgid

2) A vhost config including:

        DocumentRoot /var/www/html
        <Directory "/var/www/html">
        Options +ExecCGI
        AddHandler cgi-script .cgi


3) Perl snippet in /var/www/html/test.cgi:

#!/usr/bin/perl

print "Content-type: text/html\n\n";
print "Hello, World.";


With apache2-bin in Debian Bullseye (stable) you do NOT encounter this failure and the Apache httpd cares properly about initializing the socket for the cgid module. Let me know, if this bug has been published in the right place and/or if you need any more details about it.



Regards
Sebastian
