[Pkg-netatalk-devel] Bug#958299: netatalk: incoherent handling of groups

[Peter Keel]

Package: netatalk
Version: 3.1.12~ds-3
Severity: normal
Tags: upstream


Hi

I already reported this upstream, at 
https://sourceforge.net/p/netatalk/bugs/660/
But I thought I stell want to report it here: 


This user "person" is, apart from being in the default group "users" also in the auxiliary group "cc".

# grep person /etc/group
team:x:1001:person
cc:x:1056:person

# grep :100: /etc/group
users:x:100:

# grep person /etc/passwd
person:x:1135:100:Test Person:/home/person:/bin/bash

With this group cc, she has read-only access to the main share, and red-write to a subdirectory of this share:

[Share]
    path = /share
    valid users = @aa, at cc
    directory perm = 0770
    file perm = 0660
    umask = 5007
    rolist = @cc

[CC]
    path = /share/cc
    valid users = @cc
    directory perm = 0770
    file perm = 0660
    umask = 5000


If she uploads to the share cc where she has write-access, this here can happen:

# ls /share/cc
drwxrwsrwx  9 person    users 4096 Apr 20 08:35 200304
drwxrwsr-x  3 person    cc    4096 Apr 20 10:37 200415


Yes, these are two directory she uploaded today.

Which group and umask will be used is completely unpredictable.



Please note, that below list of automatically detected configfiles is 
completely incorrect for netatalk 3; the only configs expected there are
afp.conf, dbus-session.conf and extmap.conf. The others are netatalk
2.
