6 qmail_queue_selinux - Security Enhanced Linux Policy for the
7 qmail_queue processes
8
10 Security-Enhanced Linux secures the qmail_queue processes via flexible
11 mandatory access control.
12 The qmail_queue processes execute with the qmail_queue_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_queue_t
20
24 The qmail_queue_t SELinux type can be entered via the
25 qmail_queue_exec_t file type.
26 The default entrypoint paths for the qmail_queue_t domain are the fol‐
28 lowing:
29 /var/qmail/bin/qmail-queue
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_queue policy is very flexible allowing users to setup their
40 qmail_queue processes in as secure a method as possible.
41 The following process types are defined for qmail_queue:
43 qmail_queue_t
45 Note: semanage permissive -a qmail_queue_t can be used to make the
47 process type qmail_queue_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_queue policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_queue with the tight‐
56 est access possible.
57 If you want to deny any process from ptracing or debugging any other
61 processes, you must turn on the deny_ptrace boolean. Enabled by
62 default.
63 setsebool -P deny_ptrace 1
65 If you want to allow any process to mmap any file on system with
69 attribute file_type, you must turn on the domain_can_mmap_files bool‐
70 ean. Enabled by default.
71 setsebool -P domain_can_mmap_files 1
73 If you want to allow all domains write to kmsg_device, while kernel is
77 executed with systemd.log_target=kmsg parameter, you must turn on the
78 domain_can_write_kmsg boolean. Disabled by default.
79 setsebool -P domain_can_write_kmsg 1
81 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the domain_fd_use boolean. Enabled by default.
86 setsebool -P domain_fd_use 1
88 If you want to allow all domains to have the kernel load modules, you
92 must turn on the domain_kernel_load_modules boolean. Disabled by
93 default.
94 setsebool -P domain_kernel_load_modules 1
96 If you want to allow all domains to execute in fips_mode, you must turn
100 on the fips_mode boolean. Enabled by default.
101 setsebool -P fips_mode 1
103 If you want to determine whether Gitosis can send mail, you must turn
107 on the gitosis_can_sendmail boolean. Disabled by default.
108 setsebool -P gitosis_can_sendmail 1
110 If you want to enable reading of urandom for all domains, you must turn
114 on the global_ssp boolean. Disabled by default.
115 setsebool -P global_ssp 1
117 If you want to allow http daemon to send mail, you must turn on the
121 httpd_can_sendmail boolean. Disabled by default.
122 setsebool -P httpd_can_sendmail 1
124 If you want to allow Redis to run redis-sentinal notification scripts,
128 you must turn on the redis_enable_notify boolean. Disabled by default.
129 setsebool -P redis_enable_notify 1

135 The SELinux process type qmail_queue_t can manage files labeled with
136 the following file types. The paths listed are the default paths for
137 these file types. Note the processes UID still need to have DAC per‐
138 missions.
139 arpwatch_tmp_t
141 qmail_spool_t
144 /var/qmail/queue(/.*)?
146
149 SELinux requires files to have an extended attribute to define the file
150 type.
151 You can see the context of a file using the -Z option to ls
153 Policy governs the access confined processes have to these files.
155 SELinux qmail_queue policy is very flexible allowing users to setup
156 their qmail_queue processes in as secure a method as possible.
157 The following file types are defined for qmail_queue:
159 qmail_queue_exec_t
163 - Set files with the qmail_queue_exec_t type, if you want to transition
165 an executable to the qmail_queue_t domain.
166 Note: File context can be temporarily modified with the chcon command.
170 If you want to permanently change the file context you need to use the
171 semanage fcontext command. This will modify the SELinux labeling data‐
172 base. You will need to use restorecon to apply the labels.
173
176 semanage fcontext can also be used to manipulate default file context
177 mappings.
178 semanage permissive can also be used to manipulate whether or not a
180 process type is permissive.
181 semanage module can also be used to enable/disable/install/remove pol‐
183 icy modules.
184 semanage boolean can also be used to manipulate the booleans
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
189 icy settings.
