6 qmail_rspawn_selinux - Security Enhanced Linux Policy for the
7 qmail_rspawn processes
8
10 Security-Enhanced Linux secures the qmail_rspawn processes via flexible
11 mandatory access control.
12
13 The qmail_rspawn processes execute with the qmail_rspawn_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep qmail_rspawn_t
20
21
22
24 The qmail_rspawn_t SELinux type can be entered via the
25 qmail_rspawn_exec_t file type.
26
27 The default entrypoint paths for the qmail_rspawn_t domain are the fol‐
28 lowing:
29
30 /var/qmail/bin/qmail-rspawn
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_rspawn policy is very flexible allowing users to setup their
40 qmail_rspawn processes in as secure a method as possible.
41
42 The following process types are defined for qmail_rspawn:
43
44 qmail_rspawn_t
45
46 Note: semanage permissive -a qmail_rspawn_t can be used to make the
47 process type qmail_rspawn_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_rspawn policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_rspawn 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

65
66
68 The SELinux process type qmail_rspawn_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 qmail_spool_t
74
75 /var/qmail/queue(/.*)?
76
77
79 SELinux requires files to have an extended attribute to define the file
80 type.
81
82 You can see the context of a file using the -Z option to ls
83
84 Policy governs the access confined processes have to these files.
85 SELinux qmail_rspawn policy is very flexible allowing users to setup
86 their qmail_rspawn processes in as secure a method as possible.
87
88 STANDARD FILE CONTEXT
89
90 SELinux defines the file context types for the qmail_rspawn, if you
91 wanted to store files with these types in a different paths, you need
92 to execute the semanage command to specify alternate labeling and then
93 use restorecon to put the labels on disk.
94
95 semanage fcontext -a -t qmail_rspawn_exec_t '/srv/qmail_rspawn/con‐
96 tent(/.*)?'
97 restorecon -R -v /srv/myqmail_rspawn_content
98
99 Note: SELinux often uses regular expressions to specify labels that
100 match multiple files.
101
102 The following file types are defined for qmail_rspawn:
103
104
105
106 qmail_rspawn_exec_t
107
108 - Set files with the qmail_rspawn_exec_t type, if you want to transi‐
109 tion an executable to the qmail_rspawn_t domain.
110
111
112
113 Note: File context can be temporarily modified with the chcon command.
114 If you want to permanently change the file context you need to use the
115 semanage fcontext command. This will modify the SELinux labeling data‐
116 base. You will need to use restorecon to apply the labels.
117
118
120 semanage fcontext can also be used to manipulate default file context
121 mappings.
122
123 semanage permissive can also be used to manipulate whether or not a
124 process type is permissive.
125
126 semanage module can also be used to enable/disable/install/remove pol‐
127 icy modules.
128
129 semanage boolean can also be used to manipulate the booleans
130
131
132 system-config-selinux is a GUI tool available to customize SELinux pol‐
133 icy settings.
