6 qmail_queue_selinux - Security Enhanced Linux Policy for the
7 qmail_queue processes
8
10 Security-Enhanced Linux secures the qmail_queue processes via flexible
11 mandatory access control.
12
13 The qmail_queue processes execute with the qmail_queue_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep qmail_queue_t
20
21
22
24 The qmail_queue_t SELinux type can be entered via the
25 qmail_queue_exec_t file type.
26
27 The default entrypoint paths for the qmail_queue_t domain are the fol‐
28 lowing:
29
30 /var/qmail/bin/qmail-queue
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 qmail_queue policy is very flexible allowing users to setup their
40 qmail_queue processes in as secure a method as possible.
41
42 The following process types are defined for qmail_queue:
43
44 qmail_queue_t
45
46 Note: semanage permissive -a qmail_queue_t can be used to make the
47 process type qmail_queue_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 qmail_queue policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_queue with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type qmail_queue_t can manage files labeled with
69 the following file types. The paths listed are the default paths for
70 these file types. Note the processes UID still need to have DAC per‐
71 missions.
72
73 arpwatch_tmp_t
74
75
76 qmail_spool_t
77
78 /var/qmail/queue(/.*)?
79
80
82 SELinux requires files to have an extended attribute to define the file
83 type.
84
85 You can see the context of a file using the -Z option to ls
86
87 Policy governs the access confined processes have to these files.
88 SELinux qmail_queue policy is very flexible allowing users to setup
89 their qmail_queue processes in as secure a method as possible.
90
91 STANDARD FILE CONTEXT
92
93 SELinux defines the file context types for the qmail_queue, if you
94 wanted to store files with these types in a different paths, you need
95 to execute the semanage command to specify alternate labeling and then
96 use restorecon to put the labels on disk.
97
98 semanage fcontext -a -t qmail_queue_exec_t '/srv/qmail_queue/con‐
99 tent(/.*)?'
100 restorecon -R -v /srv/myqmail_queue_content
101
102 Note: SELinux often uses regular expressions to specify labels that
103 match multiple files.
104
105 The following file types are defined for qmail_queue:
106
107
108
109 qmail_queue_exec_t
110
111 - Set files with the qmail_queue_exec_t type, if you want to transition
112 an executable to the qmail_queue_t domain.
113
114
115
116 Note: File context can be temporarily modified with the chcon command.
117 If you want to permanently change the file context you need to use the
118 semanage fcontext command. This will modify the SELinux labeling data‐
119 base. You will need to use restorecon to apply the labels.
120
121
123 semanage fcontext can also be used to manipulate default file context
124 mappings.
125
126 semanage permissive can also be used to manipulate whether or not a
127 process type is permissive.
128
129 semanage module can also be used to enable/disable/install/remove pol‐
130 icy modules.
131
132 semanage boolean can also be used to manipulate the booleans
133
134
135 system-config-selinux is a GUI tool available to customize SELinux pol‐
136 icy settings.
