6 postfix_showq_selinux - Security Enhanced Linux Policy for the post‐
7 fix_showq processes
8
10 Security-Enhanced Linux secures the postfix_showq processes via flexi‐
11 ble mandatory access control.
12
13 The postfix_showq processes execute with the postfix_showq_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 postfix_showq_t
20
21
22
24 The postfix_showq_t SELinux type can be entered via the post‐
25 fix_showq_exec_t file type.
26
27 The default entrypoint paths for the postfix_showq_t domain are the
28 following:
29
30 /usr/libexec/postfix/showq
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 postfix_showq policy is very flexible allowing users to setup their
40 postfix_showq processes in as secure a method as possible.
41
42 The following process types are defined for postfix_showq:
43
44 postfix_showq_t
45
46 Note: semanage permissive -a postfix_showq_t can be used to make the
47 process type postfix_showq_t permissive. SELinux does not deny access
48 to 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. post‐
54 fix_showq policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run postfix_showq with the
56 tightest access possible.
57
58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type postfix_showq_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101
102 anon_inodefs_t
103
104
105 postfix_var_run_t
106
107 /var/spool/postfix/pid/.*
108
109
111 SELinux requires files to have an extended attribute to define the file
112 type.
113
114 You can see the context of a file using the -Z option to ls
115
116 Policy governs the access confined processes have to these files.
117 SELinux postfix_showq policy is very flexible allowing users to setup
118 their postfix_showq processes in as secure a method as possible.
119
120 The following file types are defined for postfix_showq:
121
122
123
124 postfix_showq_exec_t
125
126 - Set files with the postfix_showq_exec_t type, if you want to transi‐
127 tion an executable to the postfix_showq_t domain.
128
129
130
131 Note: File context can be temporarily modified with the chcon command.
132 If you want to permanently change the file context you need to use the
133 semanage fcontext command. This will modify the SELinux labeling data‐
134 base. You will need to use restorecon to apply the labels.
135
136
138 semanage fcontext can also be used to manipulate default file context
139 mappings.
140
141 semanage permissive can also be used to manipulate whether or not a
142 process type is permissive.
143
144 semanage module can also be used to enable/disable/install/remove pol‐
145 icy modules.
146
147 semanage boolean can also be used to manipulate the booleans
148
149
150 system-config-selinux is a GUI tool available to customize SELinux pol‐
151 icy settings.
