In order to make CVSweb operate in a chroot environment, it is
necessary to copy all of the relevant tools, libraries, and perl modules
that CVSweb employs into /var/www.
First, create the basic directory structure:
$ cd /var/www
# mkdir {tmp,usr}
# chown www:www tmp (needs to be writeable for the www user)
$ cd /var/www/usr
# mkdir -p {bin,lib,libdata/perl5,libexec}
$ cd /var/www/usr/libdata/perl5
# mkdir -p {File,IPC,Time,warnings,`machine`-openbsd/5.8.6}
Now, the required binaries:
$ cd /var/www/usr/bin
# cp -p /usr/bin/{co,cvs,diff,perl,rcsdiff,rlog,uname} .
Next, the libraries that the binaries are linked to:
NOTE: Wildcards will, of course, copy any old, unused libraries that are
lurking around (for example, from an upgrade):
$ cd /var/www/usr/lib
# cp -p /usr/lib/lib{c,crypto,des,gssapi,krb5,m,perl,util,z}.so* .
Now, the run-time link-editor:
$ cd /var/www/usr/libexec
# cp -p /usr/libexec/ld.so .
And finally, the perl modules:
$ cd /var/www/usr/libdata/perl5
# cp -p /usr/libdata/perl5/{Carp,Exporter,Symbol,base,integer}.pm .
# cp -p /usr/libdata/perl5/{strict,warnings,vars}.pm .
# cp -p /usr/libdata/perl5/File/Basename.pm ./File/
# cp -p /usr/libdata/perl5/IPC/Open{2,3}.pm ./IPC/
# cp -p /usr/libdata/perl5/Time/Local.pm ./Time/
# cp -p /usr/libdata/perl5/warnings/register.pm ./warnings/
$ cd /var/www/usr/libdata/perl5/`machine`-openbsd/5.8.6
# cp -p /usr/libdata/perl5/`machine`-openbsd/5.8.6/{Config,Cwd}.pm .
Editing cvsweb and cvsweb.conf
------------------------------
The cvsweb program itself and cvsweb.conf both assume Apache is not
running in a chroot environment, so we need to change some default paths
so they are relative to /var/www.
In /var/www/cgi-bin/cvsweb:
for ("$mydir/cvsweb.conf", '/var/www/conf/cvsweb/cvsweb.conf') {
for ("$mydir/cvsweb.conf", '/conf/cvsweb/cvsweb.conf') {
In /var/www/conf/cvsweb/cvsweb.conf:
Change CVSrepositories to reflect the location of the directories which
contain CVSROOT. This example shows a local repository NFS mounted over
loopback into /var/www/cvs, since the directory must be relative to
/var/www, we use /cvs.
@CVSrepositories = (
'local' => ['Local Repository', '/home/cvs'], (default)
'local' => ['Local Repository', '/cvs'], (chroot)
And the same idea for $mimetypes:
$mime_types = '/var/www/conf/mime.types'; (default)
$mime_types = '/conf/mime.types'; (chroot)
