6 qmail_start_selinux - Security Enhanced Linux Policy for the
7 qmail_start processes
8
10 Security-Enhanced Linux secures the qmail_start processes via flexible
11 mandatory access control.
12 The qmail_start processes execute with the qmail_start_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep qmail_start_t
20
24 The qmail_start_t SELinux type can be entered via the
25 qmail_start_exec_t file type.
26 The default entrypoint paths for the qmail_start_t domain are the fol‐
28 lowing:
29 /var/qmail/bin/qmail-start
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_start policy is very flexible allowing users to setup their
40 qmail_start processes in as secure a method as possible.
41 The following process types are defined for qmail_start:
43 qmail_start_t
45 Note: semanage permissive -a qmail_start_t can be used to make the
47 process type qmail_start_t permissive. SELinux does not deny access to
48 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_start policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_start with the tight‐
56 est access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the daemons_dump_core boolean. Disabled by default.
62 setsebool -P daemons_dump_core 1
64 If you want to enable cluster mode for daemons, you must turn on the
68 daemons_enable_cluster_mode boolean. Enabled by default.
69 setsebool -P daemons_enable_cluster_mode 1
71 If you want to allow all daemons to use tcp wrappers, you must turn on
75 the daemons_use_tcp_wrapper boolean. Disabled by default.
76 setsebool -P daemons_use_tcp_wrapper 1
78 If you want to allow all daemons the ability to read/write terminals,
82 you must turn on the daemons_use_tty boolean. Disabled by default.
83 setsebool -P daemons_use_tty 1
85 If you want to deny any process from ptracing or debugging any other
89 processes, you must turn on the deny_ptrace boolean. Enabled by
90 default.
91 setsebool -P deny_ptrace 1
93 If you want to allow any process to mmap any file on system with
97 attribute file_type, you must turn on the domain_can_mmap_files bool‐
98 ean. Enabled by default.
99 setsebool -P domain_can_mmap_files 1
101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

142 The SELinux process type qmail_start_t can manage files labeled with
143 the following file types. The paths listed are the default paths for
144 these file types. Note the processes UID still need to have DAC per‐
145 missions.
146 cluster_conf_t
148 /etc/cluster(/.*)?
150 cluster_var_lib_t

184 SELinux requires files to have an extended attribute to define the file
185 type.
186 You can see the context of a file using the -Z option to ls
188 Policy governs the access confined processes have to these files.
190 SELinux qmail_start policy is very flexible allowing users to setup
191 their qmail_start processes in as secure a method as possible.
192 The following file types are defined for qmail_start:
194 qmail_start_exec_t
198 - Set files with the qmail_start_exec_t type, if you want to transition
200 an executable to the qmail_start_t domain.
201 Note: File context can be temporarily modified with the chcon command.
205 If you want to permanently change the file context you need to use the
206 semanage fcontext command. This will modify the SELinux labeling data‐
207 base. You will need to use restorecon to apply the labels.
208
211 semanage fcontext can also be used to manipulate default file context
212 mappings.
213 semanage permissive can also be used to manipulate whether or not a
215 process type is permissive.
216 semanage module can also be used to enable/disable/install/remove pol‐
218 icy modules.
219 semanage boolean can also be used to manipulate the booleans
221 system-config-selinux is a GUI tool available to customize SELinux pol‐
224 icy settings.
