6 qmail_tcp_env_selinux - Security Enhanced Linux Policy for the
7 qmail_tcp_env processes
8
10 Security-Enhanced Linux secures the qmail_tcp_env processes via flexi‐
11 ble mandatory access control.
12 The qmail_tcp_env processes execute with the qmail_tcp_env_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep qmail_tcp_env_t
20
24 The qmail_tcp_env_t SELinux type can be entered via the
25 qmail_tcp_env_exec_t file type.
26 The default entrypoint paths for the qmail_tcp_env_t domain are the
28 following:
29 /var/qmail/bin/tcp-env
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 qmail_tcp_env policy is very flexible allowing users to setup their
40 qmail_tcp_env processes in as secure a method as possible.
41 The following process types are defined for qmail_tcp_env:
43 qmail_tcp_env_t
45 Note: semanage permissive -a qmail_tcp_env_t can be used to make the
47 process type qmail_tcp_env_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 qmail_tcp_env policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run qmail_tcp_env with the
56 tightest access possible.
57 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 setsebool -P fips_mode 1
64
68 SELinux requires files to have an extended attribute to define the file
69 type.
70 You can see the context of a file using the -Z option to ls
72 Policy governs the access confined processes have to these files.
74 SELinux qmail_tcp_env policy is very flexible allowing users to setup
75 their qmail_tcp_env processes in as secure a method as possible.
76 STANDARD FILE CONTEXT
78 SELinux defines the file context types for the qmail_tcp_env, if you
80 wanted to store files with these types in a different paths, you need
81 to execute the semanage command to specify alternate labeling and then
82 use restorecon to put the labels on disk.
83 semanage fcontext -a -t qmail_tcp_env_exec_t '/srv/qmail_tcp_env/con‐
85 tent(/.*)?'
86 restorecon -R -v /srv/myqmail_tcp_env_content
87 Note: SELinux often uses regular expressions to specify labels that
89 match multiple files.
90 The following file types are defined for qmail_tcp_env:
92 qmail_tcp_env_exec_t
96 - Set files with the qmail_tcp_env_exec_t type, if you want to transi‐
98 tion an executable to the qmail_tcp_env_t domain.
99 Note: File context can be temporarily modified with the chcon command.
103 If you want to permanently change the file context you need to use the
104 semanage fcontext command. This will modify the SELinux labeling data‐
105 base. You will need to use restorecon to apply the labels.
106
109 semanage fcontext can also be used to manipulate default file context
110 mappings.
111 semanage permissive can also be used to manipulate whether or not a
113 process type is permissive.
114 semanage module can also be used to enable/disable/install/remove pol‐
116 icy modules.
117 semanage boolean can also be used to manipulate the booleans
119 system-config-selinux is a GUI tool available to customize SELinux pol‐
122 icy settings.
