6 qmail_lspawn_selinux - Security Enhanced Linux Policy for the
7 qmail_lspawn processes
8
10 Security-Enhanced Linux secures the qmail_lspawn processes via flexible
11 mandatory access control.
12
13 The qmail_lspawn processes execute with the qmail_lspawn_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_lspawn_t
20
21
22
24 The qmail_lspawn_t SELinux type can be entered via the
25 qmail_lspawn_exec_t file type.
26
27 The default entrypoint paths for the qmail_lspawn_t domain are the fol‐
28 lowing:
29
30 /var/qmail/bin/qmail-lspawn
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_lspawn policy is very flexible allowing users to setup their
40 qmail_lspawn processes in as secure a method as possible.
41
42 The following process types are defined for qmail_lspawn:
43
44 qmail_lspawn_t
45
46 Note: semanage permissive -a qmail_lspawn_t can be used to make the
47 process type qmail_lspawn_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_lspawn policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_lspawn 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_lspawn_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.

108 SELinux requires files to have an extended attribute to define the file
109 type.
110
111 You can see the context of a file using the -Z option to ls
112
113 Policy governs the access confined processes have to these files.
114 SELinux qmail_lspawn policy is very flexible allowing users to setup
115 their qmail_lspawn processes in as secure a method as possible.
116
117 STANDARD FILE CONTEXT
118
119 SELinux defines the file context types for the qmail_lspawn, if you
120 wanted to store files with these types in a different paths, you need
121 to execute the semanage command to specify alternate labeling and then
122 use restorecon to put the labels on disk.
123
124 semanage fcontext -a -t qmail_lspawn_exec_t '/srv/qmail_lspawn/con‐
125 tent(/.*)?'
126 restorecon -R -v /srv/myqmail_lspawn_content
127
128 Note: SELinux often uses regular expressions to specify labels that
129 match multiple files.
130
131 The following file types are defined for qmail_lspawn:
132
133
134
135 qmail_lspawn_exec_t
136
137 - Set files with the qmail_lspawn_exec_t type, if you want to transi‐
138 tion an executable to the qmail_lspawn_t domain.
139
140
141
142 Note: File context can be temporarily modified with the chcon command.
143 If you want to permanently change the file context you need to use the
144 semanage fcontext command. This will modify the SELinux labeling data‐
145 base. You will need to use restorecon to apply the labels.
146
147
149 semanage fcontext can also be used to manipulate default file context
150 mappings.
151
152 semanage permissive can also be used to manipulate whether or not a
153 process type is permissive.
154
155 semanage module can also be used to enable/disable/install/remove pol‐
156 icy modules.
157
158 semanage boolean can also be used to manipulate the booleans
159
160
161 system-config-selinux is a GUI tool available to customize SELinux pol‐
162 icy settings.
