=head1 NAME
FS::UID - Subroutines for database login and assorted other stuff
=head1 SYNOPSIS
use FS::UID qw(adminsuidsetup cgisuidsetup dbh datasrc getotaker
checkeuid checkruid swapuid);
adminsuidsetup;
$cgi = new CGI::Base;
$cgi->get;
$dbh = cgisuidsetup($cgi);
$dbh = dbh;
$datasrc = datasrc;
=head1 DESCRIPTION
Provides a hodgepodge of subroutines.
=head1 SUBROUTINES
=over 4
=item adminsuidsetup
Cleans the environment.
Make sure the script is running as freeside, or setuid freeside.
Opens a connection to the database.
Swaps real and effective UIDs.
Returns the DBI database handle (usually you don't need this).
=cut
sub adminsuidsetup {
$ENV{'PATH'} ='/usr/local/bin:/usr/bin:/usr/ucb:/bin';
$ENV{'SHELL'} = '/bin/sh';
$ENV{'IFS'} = " \t\n";
$ENV{'CDPATH'} = '';
$ENV{'ENV'} = '';
$ENV{'BASH_ENV'} = '';
croak "Not running uid freeside!" unless checkeuid();
$dbh = DBI->connect($datasrc,$db_user,$db_pass, {
# hack for web demo
# my($user)=getotaker();
# $dbh = DBI->connect("$datasrc:$user",$db_user,$db_pass, {
'AutoCommit' => 'true',
'ChopBlanks' => 'true',
} ) or die "DBI->connect error: $DBI::errstr\n";;
swapuid(); #go to non-privledged user if running setuid freeside
$dbh;
}
=item cgisuidsetup CGI::Base_OBJECT
Stores the CGI::Base_OBJECT for later use.
Runs adminsuidsetup.
=cut
sub cgisuidsetup {
$cgi=$_[0];
adminsuidsetup;
}
=item dbh
Returns the DBI database handle.
=cut
sub dbh {
$dbh;
}
=item datasrc
Returns the DBI data source.
=cut
sub datasrc {
$datasrc;
}
#hack for web demo
#sub setdbh {
# $dbh=$_[0];
#}
sub suidsetup {
croak "suidsetup depriciated";
}
=item getotaker
Returns the current Freeside user. Currently that means the CGI REMOTE_USER,
or 'freeside'.
=cut
sub getotaker {
if ($cgi && defined $cgi->var('REMOTE_USER')) {
return $cgi->var('REMOTE_USER'); #for now
} else {
'freeside';
}
}
=item checkeuid
Returns true if effective UID is that of the freeside user.
=cut
sub checkeuid {
( $> == $freeside_uid );
}
=item checkruid
Returns true if the real UID is that of the freeside user.
=cut
sub checkruid {
( $< == $freeside_uid );
}
=item swapuid
Swaps real and effective UIDs.
=cut
sub swapuid {
($<,$>) = ($>,$<);
}
=back
=head1 BUGS
Not OO.
No capabilities yet. When mod_perl and Authen::DBI are implemented,
cgisuidsetup will go away as well.
=head1 SEE ALSO
L<FS::Record>, L<CGI::Base>, L<DBI>
=head1 HISTORY
ivan@voicenet.com 97-jun-4 - 9
untaint otaker ivan@voicenet.com 97-jul-7
generalize and auto-get uid (getotaker still needs to be db'ed)
ivan@sisd.com 97-nov-10
&cgisuidsetup logs into database. other cleaning.
ivan@sisd.com 97-nov-22,23
&adminsuidsetup logs into database with otaker='freeside' (for
automated tasks like billing)
ivan@sisd.com 97-dec-13
added sub datasrc for fs-setup ivan@sisd.com 98-feb-21
datasrc, user and pass now come from conf/secrets ivan@sisd.com 98-jun-28
added ChopBlanks to DBI call (see man DBI) ivan@sisd.com 98-aug-16
pod, use FS::Conf, implemented cgisuidsetup as adminsuidsetup,
inlined suidsetup
