6 qmail_remote_selinux - Security Enhanced Linux Policy for the
7 qmail_remote processes
8
10 Security-Enhanced Linux secures the qmail_remote processes via flexible
11 mandatory access control.
12
13 The qmail_remote processes execute with the qmail_remote_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_remote_t
20
21
22
24 The qmail_remote_t SELinux type can be entered via the
25 qmail_remote_exec_t file type.
26
27 The default entrypoint paths for the qmail_remote_t domain are the fol‐
28 lowing:
29
30 /var/qmail/bin/qmail-remote
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_remote policy is very flexible allowing users to setup their
40 qmail_remote processes in as secure a method as possible.
41
42 The following process types are defined for qmail_remote:
43
44 qmail_remote_t
45
46 Note: semanage permissive -a qmail_remote_t can be used to make the
47 process type qmail_remote_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_remote policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_remote with the tight‐
56 est access possible.
57
58
59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow sysadm to debug or ptrace all processes, you must
68 turn on the allow_ptrace boolean. Disabled by default.
69
70 setsebool -P allow_ptrace 1
71
72
73
74 If you want to allow all domains to have the kernel load modules, you
75 must turn on the domain_kernel_load_modules boolean. Disabled by
76 default.
77
78 setsebool -P domain_kernel_load_modules 1
79
80
81
82 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84
85 setsebool -P fips_mode 1
86
87
88
89 If you want to enable reading of urandom for all domains, you must turn
90 on the global_ssp boolean. Disabled by default.
91
92 setsebool -P global_ssp 1
93
94
95
97 The SELinux process type qmail_remote_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 initrc_tmp_t
103
104
105 mnt_t
106
107 /mnt(/[^/]*)
108 /mnt(/[^/]*)?
109 /rhev(/[^/]*)?
110 /media(/[^/]*)

112 /etc/rhgb(/.*)?

122
123 tmp_t
124
125 /tmp
126 /usr/tmp

128 /tmp-inst

134 SELinux requires files to have an extended attribute to define the file
135 type.
136
137 You can see the context of a file using the -Z option to ls
138
139 Policy governs the access confined processes have to these files.
140 SELinux qmail_remote policy is very flexible allowing users to setup
141 their qmail_remote processes in as secure a method as possible.
142
143 The following file types are defined for qmail_remote:
144
145
146
147 qmail_remote_exec_t
148
149 - Set files with the qmail_remote_exec_t type, if you want to transi‐
150 tion an executable to the qmail_remote_t domain.
151
152
153
154 Note: File context can be temporarily modified with the chcon command.
155 If you want to permanently change the file context you need to use the
156 semanage fcontext command. This will modify the SELinux labeling data‐
157 base. You will need to use restorecon to apply the labels.
158
159
161 semanage fcontext can also be used to manipulate default file context
162 mappings.
163
164 semanage permissive can also be used to manipulate whether or not a
165 process type is permissive.
166
167 semanage module can also be used to enable/disable/install/remove pol‐
168 icy modules.
169
170 semanage boolean can also be used to manipulate the booleans
171
172
173 system-config-selinux is a GUI tool available to customize SELinux pol‐
174 icy settings.
