Bug 17717: Add a --chdir option switch for koha-foreach

Until Perl 5.26, the current directory is added to @INC when running a
Perl script [1]. Having the current directory in @INC means it can be
tried to be traversed when performing a lib lookup. Since version 5.18,
Perl dies when it finds an unreadable directory (permissions) in @INC
that needs to be traversed. This behaviour won't change because Perl
devs consider it an enhancement to security. [2]

Because of this, we need to make sure our scripts are ran **from** a
directory in which they have read permissions.

Ths patch adds a --chdir option switch to the **koha-foreach** wrapper
script, that makes the inner shells/scripts to be ran within the Koha
instance's user home directory.

The change is trivial and should be QAed easily. I tested this on a prod
server:

- Create a /tmp/test.pl file containing:

use Modern::Perl;

use Cwd;
my $dir = getcwd;

warn $dir;

1;

A) then create a cronjob entry to run it using koha-foreach:
(in /etc/cron.d/test):
1/* * * * * root koha-foreach perl /tmp/test.pl
- Once I noticed the cronjob ran, I used mutt to read the emails in the
root user.
=> FAIL:
...
Subject: Cron  koha-foreach --enabled perl /tmp/test.pl

"/root"
"/root"
"/root"
"/root"
"/root"
...

B) I then used the patched koha-foreach with different results:
=> SUCCESS:
...
Subject: Cron  /root/koha-foreach --chdir --enabled perl
/tmp/test.pl

"/var/lib/koha/acaderc"
"/var/lib/koha/agro"
"/var/lib/koha/anc"
"/var/lib/koha/arico"
"/var/lib/koha/artes"
...

So this patch's approach works. But...

C) master's koha-foreach seems to work just the same... I think it is
because of my previous attempt to fix this by using sudo in koha-shell.
So I think environmental conditions affect the behaviour (which shell is
configured for cron, sudo configuration, etc).



In conclusion, I think we should go ahead with this patch as it will solve
peoples issues, and it is a right solution (option #5 on the list) to
this Perl behaviour change. It doesn't cover other commands, but
followup patches could do.

I avoided /tmp as it is writable by any user... so it is an easy path
for both exploiting by replacing some lib, and also because the
existence of an unreadable dir that the interpreter could try to
traverse (unreadable /tmp/Authen or /tmp/Koha will trigger the same
error, and I assume people know what they are putting on the instance's
dir, at least it will be easier to track).

A followup patch takes care of making the cronjobs use --chdir when
calling koha-foreach

If there's a /tmp/Koha directory, without read permissions for the instance's
user it will still fail. I think we should jump into the instance's home
directory and I'm providing a patch to do so.

I'm taking care of it. I'm working on the same approach as bug 19546. Adding a
--chdir option switch to koha-foreach.

I can confirm this is still an issue on:

I would agree. Put cd /tmp very close to the sudo -u. Adding it in cron is more
confusing.

--- Comment #47 from Marco Moreno  ---
Understanding the problem is necessary to determine the best solution.

The problem is this:

- All cron jobs start in $HOME and those in /etc/cron* run as root which is
/root.
- Problems occur when using "sudo -u another_user" to demote from root to
"another_user" which does not have read access to /root.
- The @INC array is traversed when a module is to be loaded, but a recent
update to Perl 5.22 (base.pm?) now results in a fatal error when it searches a
directory that cannot be read.
- The @INC array includes the current directory ('.') which is '/root' and
unreadable by 'another_user', resulting in this error.
- This error will also occur if run from the command line in a directory which
is not readable my 'another_user'.

Normally, crons are set up in the crontab file for the user under which it
should run. 
 Since it is rather unusual for a cron to sudo to another user, this is likely
why this regression in Perl has gone largely unnoticed.

Possible solutions:

1. Fix the regression in Perl 5.22.  This is ideal and this may have already
happened in more recent versions of Perl.  However, many of us remain stuck
with the version we have and we need a solution that will with with a broken
Perl.  Not a good short-term option.

2. Avoid using "sudo -u".  While possibly ideal, it's convenient and simple for
koha-foreach to be run as a system cron and switch to the user for each
library. Therefore, this is not a good option.

3. Modify the @INC array to remove the '.' directory so that /root will never
be searched.  This could be done in a common location (e.g.
/usr/share/koha/bin/kohalib.pl) as I suggested in Comment 40.  This is risky
because it assumes that no downstream module will ever depend upon '.' having
been removed from @INC.  While this solution has worked well for me, it
probably is not ideal either.

4. Change the current directory to one that is readable by adding 'cd /tmp' to
each cron job that performs a "sudo -u".  This has become an established
workaround, but requires modifying many cron entries.  Also not an ideal
solution.

5. Change the current directory to one that is readable by modifying all code
that performs a "sudo -u".  This may be as simple as adding "cd /tmp" at the
beginning of /usr/sbin/koha-foreach and /usr/sbin/koha-rebuild-zebra.  Possibly
the best solution for now.

Option #5 seems like the best one for now.  It is a clear, one-line solution
that doesn't require modifying any crons.

Thoughts?

I ran into this problem after upgrading from

Koha 3.22, Ubuntu 14.04, Perl ?

to 

Koha 17.05.05, Ubuntu 16.04.3 LTS, Perl v5.22.1

gather_print_notices.pl run from cron (sudo crontab -e) would fail with this
error:

Running the command in the crontab on the command line would succeed, no
errors. 

Adding the "cd /tmp &&" trick in front of the commands in the crontab makes the
errors go away.

This issue is NOT fixed in 17.05.  I'm seeing this now after having upgraded
from 16.11.  However, I've discovered some things that might be helpful.

As Chris mentioned, this appears to be a bug with base.pm (IMO).  Perhaps it's
behavior has changed due to this security resolution that forces Perl to die if
a required module is cannot be read when traversing @INC:
https://rt.perl.org/Public/Bug/Display.html?id=113422

According to this post, base.pm may attempt to require a module that does not
exist and traverse the entire @INC array:
https://rt.cpan.org/Public/Bug/Display.html?id=106552#txn-1589169
Evidently, it dies as soon as it encounters a directory it cannot read.

Avoiding '.' in PERL5LIB doesn't really help since Perl already includes '.' in
@INC (also a security concern???).  Working around this means either ensuring
that '.' points to a directory that can be read (e.g. "cd /tmp") or modifying
the @INC array to remove '.' from it.

The latter seems better so I modified the BEGIN block in
/usr/share/koha/bin/kohalib.pl like this:

-
use strict;
#use warnings; FIXME - Bug 2505

my $module_dir;
BEGIN {
$module_dir = '/usr/share/koha/lib';
die if $module_dir =~ /^[_]{2}PERL_MODULE_DIR[_]{2}$/;
@INC = grep {$_ ne '.'} @INC;
}

use lib $module_dir;

1;
-

This also allows the change to be in one place and avoid having to insert a 'cd
/tmp' for each cron job.

I'm running Perl 5.22 - I wonder if it's fixed in 5.24.

--- Comment #39 from Tomás Cohen Arazi  ---
Ok, I managed to reproduce the conditions that trigger the bug.

GOOD NEWS: It is fixed in master, 16.11 and 16.05 already, as a side effect
from bug 16733.

The problem was in koha-foreach code, that is not using koha-shell but crafting
its own env instead. To reproduce the problem, as a root user run:

root$ echo $PERL5LIB

root$ . /usr/share/koha/bin/koha-functions.sh
root$ adjust_paths_dev_install kohadev
root$ echo $PERL5LIB
/home/vagrant/kohaclone

So, if adjust_paths_dev_install is not ran, and the command is run by root,
PERL5LIB is empty, and perl uses the fallback for include (i.e. '.').

This are the conditions in which cron.d/koha-common runs
process_message_queue.pl. This happened in koha-foreach code, before bug 16733.
This is the relevant code in debian/scripts/koha-foreach:

for name in $(koha-list $listopts)
do
# Optionally use alternative paths for a dev install
adjust_paths_dev_install $name

cmd=`echo "$@" | sed -e s/__instancename__/${name}/g`
(
exec 3>&1
sudo -u "$name-koha" \
env PERL5LIB=$PERL5LIB \
KOHA_CONF="/etc/koha/sites/$name/koha-conf.xml" \
${cmd} 2>&1 >&3 | sed -e "s/^/$name: /" >&2 3>&-
exec 3>&-
) | sed -e "s/^/$name: /"

done

So before the 16733 backport, PERL5LIB was incorrectly set. This script should
definitely run koha-shell -c "${cmd}" $name instead of crafting all the
environment variables.

I can reproduce a similar error with this command:

Can't locate Authen/CAS/Client.pm:   ./Authen/CAS/Client.pm: Permission denied.

So, people that can reproduce the problem, could you please paste the output of
the following command (at least the @INC part):

# As root

In comment 23, Chris says:

and

> This does only occur on perl 5.22 and up, so something changed in that.

Since Debian testing have Perl 5.24 I assumed I could reproduce the problem
with this version.

I will test with ubuntu 16.10 which has Perl 5.22. Let's hope I reproduce the
problem this time :)

I'm not sure what you are talking about. I used the /etc/cron.d/koha-common
shipped with the debian package, and I didn't change the permissions of the
'koha1-koha' user created by koha-create.

I didn't modify the sudoers file either (http://paste.koha-community.org/435)

Just tried a package install following instructions on

Same result. The cron ran process_message_queue.pl and the message queue was

Should I have specific data in message_queue to trigger the error ?

I've read the history of the bug, many times, and I understand that the problem
is with the package install, which I'm trying to mimic to understand what's
happening.

If my command succeeds, why the one with koha-foreach should fail ?

Anyway I'll try with a package install later when I have more time

I feel like you are not reading the history of the bug, it is when using the
cron job from the packages.

You are not running that.

Step 3 of the test plan says

3/ Build and install a new package (or manually update the
/etc/cron.d/koha-common file)

Not manually run some other cron job.

I am going to bed now, and looks like it has missed the release, so you will
have time to read up yourself.

You are not running it as cron, you are running it from the commandline. The
error only manifests under cron.

[Koha-bugs] [Bug 17717] process_message_queue.pl: Can't locate Authen/CAS/Client/ Response/Failure.pm

[bugzilla-daemon]

--- Comment #24 from Julian Maurice  ---
I've made a fresh install on Debian stretch (Perl 5.24) but I can't reproduce
the problem.

root@koha-stretch:~# sudo -u koha sh -c 'touch test'
touch: cannot touch 'test': Permission denied
root@koha-stretch:~# sudo -u koha sh -c 'ls'
ls: cannot open directory '.': Permission denied

As you can see I have no read nor write access to this directory, but when I
execute

root@koha-stretch:~# sudo -u koha sh -c 'PERL5LIB=/home/koha/koha
KOHA_CONF=/home/koha/etc/koha-conf.xml perl
/home/koha/koha/misc/cronjobs/process_message_queue.pl'

I have no errors and the message queue is processed.

Can you tell me what I'm doing wrong ?

--- Comment #23 from Chris Cormack  ---
Ok

The original report of the error describes the problem, so I don't think i need
to go proving it exists?

I'll do a summary anyway. With perl 5.22 with latest ubuntu, debian testing and
above, etc have. Something has changed in the way it deals with modules that
have multiple packages in them.
This is not unique to this module, if you search for 
Permission denied at /usr/share/perl/5.22/base.pm line 97
You will see  others doing it too

EG
 I've noticed that Object::InsideOut v3.98 fails when the current directory is
not readable by the user running the Perl binary.  Most Perl modules don't have
this requirement, and so OIO creates a very cryptic error message when you run
it in such circumstances.

However Authen::CAS::Client is a module we use, that is loaded by one of the
modules that process_message_queue.pl uses. 
By adding cd /tmp &&  to the cron we make sure we avoid the not readable part.

Of course running as root gets round this too.
This is not a fix, like I said, but a simple workaround so that notices get
sent in Koha on perl 5.22. Until this module is replaced (which it is going to
be) or another solution involving changing how koha-for-each works under cron
(it works fine on the command line) is done.

This does only occur on perl 5.22 and up, so something changed in that.

Why does Perl need write access to the current directory for loading a module ?

> Can't locate Authen/CAS/Client/Response/Failure.pm:   
> ./Authen/CAS/Client/Response/Failure.pm: Permission denied at

suggests that ./Authen/CAS/Client/Response/Failure.pm exists but is not
readable. This file shouldn't exist as Authen::CAS::Client::Response::Failure
is defined in Authen/CAS/Client/Response.pm. Why does it exist ?

(In reply to Josef Moravec from comment #20)
> To test

Why ? What could possibly happen during process_message_queue.pl that trigger
an error related to a CAS module ?

And why the solution to this problem is 'cd /tmp' ? :)

Yep thats because you are running the script as root then. Root has permission
to write in that dir. With for-each you are running as the user, it doesn't.

However the real problem is this module. Which we need to replace, the
workaround should hold for then

I am working on replacing this module with one that supports CAS 2.0 and doesnt
have this problem.
It won't obviously be ready in time though. So I will write a patch to add the
cd /tmp && and attach it to here.

Should be ready soon

Just a FYI on this. I found that *not* using koha-foreach, and instead use the
actual koha instance user also works.

For example, instead of:
root koha-foreach --enabled --email
/usr/share/koha/bin/cronjobs/process_message_queue.pl

if you use:
INST-koha /usr/share/koha/bin/cronjobs/process_message_queue.pl

it works. 

So taking a look at how koha-foreach switches to the user might provide some
clues. 

Can confirm this also happens on Debian 8.4.

We could do a patch that adds the cd /tmp && 

Otherwise we could try to fix the upstream module, to work better with perl
5.22 and cron.

But yeah, it's an upstream problem, I think the module is pretty much
unmaintained, maybe finding a better module is a better plan.

Maybe the cd /tmp && for cron patch, and then work on a long term solution?

I get pretty much the exact same error when trying a koha-rebuild-zebra, so I
think this is a bit more generic than the message queue.

The error occurs in a file not supplied by Koha, and when called from a core
perl file for perl 5.22. It seems 5.18 (the perl version from Ubuntu 14.04)
does things differently than 5.22 does.

It all looks weird, because the CAS code from Ubuntu 14.04 is pretty much the
same as the one from 16.04, so that method of using multiple modules in a
single file seems to have worked better back then. I think I'll have to back
out to 14.04 again for the time being, without being able to run plack.

Separating Exception.pm seemed to have broken other things, so I've backed out
of it.

--- Comment #4 from mjn...@gmail.com ---
Futher, after separating Exception.pm, we get:

ourlib: Class Koha::Exceptions::Exception appears to be a typo as it is only
specified in the 'isa' param for
Koha::Exceptions::Virtualshelves::InvalidInviteKey
ourlib: BEGIN failed--compilation aborted at
/usr/share/koha/lib/Koha/Exceptions.pm line 41,  line 755.
.
.

Exceptions.pm itself has many references to Exception (I didn't separate all of
them).

Anyhow, I think all the above problems are just a source of one very small
thing which I'm not seeing / understanding. I doubt the classes needed to be
separated out...

--- Comment #3 from mjn...@gmail.com ---
After separating Failure.pm, the emails are now showing the same problem with
Success.pm.
After extracting Success.pm in the same way, now it complains about
Exceptions.pm :

Can't locate Koha/Exceptions/Exception.pm:   ./Koha/Exceptions/Exception.pm:
Permission denied at /usr/share/perl/5.22/base.pm line 97,  line 755

Seems like a problem with the build, or (the current version of?) perl not
supporting multiple classes within a .pm file?

--- Comment #2 from mjn...@gmail.com ---
After extracting Failure to its own file, process_message_queue.pl runs without
a peep. I don't understand enough of Perl to know what's going on.

Files end up like this:

root@koha:/usr/share/perl5/Authen/CAS/Client# find
.
./Response.pm.bak
./Response
./Response/Failure.pm
./Response.pm

Failure.pm is cut out of Response.pm: (didn't have much success with multi-line
comments!)

root@koha:/usr/share/perl5/Authen/CAS/Client# cat Response/Failure.pm
require 5.006_001;

use strict;
use warnings;

#==
# Authen::CAS::Client::Response::Failure
#
package Authen::CAS::Client::Response::Failure;

use base qw/ Authen::CAS::Client::Response /;

sub _ATTRIBUTES () { code => undef, message => '', $_[0]->SUPER::_ATTRIBUTES }

sub new { my $class = shift; $class->SUPER::new( @_, _ok => 0 ) }

sub code{ my ( $self ) = @_; $self->{code} }
sub message { my ( $self ) = @_; $self->{message} }
