6 postfix_showq_selinux - Security Enhanced Linux Policy for the post‐
7 fix_showq processes
8
10 Security-Enhanced Linux secures the postfix_showq processes via flexi‐
11 ble mandatory access control.
12 The postfix_showq processes execute with the postfix_showq_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 postfix_showq_t
20
24 The postfix_showq_t SELinux type can be entered via the post‐
25 fix_showq_exec_t file type.
26 The default entrypoint paths for the postfix_showq_t domain are the
28 following:
29 /usr/libexec/postfix/showq
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 postfix_showq policy is very flexible allowing users to setup their
40 postfix_showq processes in as secure a method as possible.
41 The following process types are defined for postfix_showq:
43 postfix_showq_t
45 Note: semanage permissive -a postfix_showq_t can be used to make the
47 process type postfix_showq_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. post‐
54 fix_showq policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run postfix_showq with the
56 tightest access possible.
57 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 setsebool -P allow_domain_fd_use 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112 setsebool -P nscd_use_shm 1

118 The SELinux process type postfix_showq_t can manage files labeled with
119 the following file types. The paths listed are the default paths for
120 these file types. Note the processes UID still need to have DAC per‐
121 missions.
122 anon_inodefs_t
124 initrc_tmp_t
127 mnt_t
130 /mnt(/[^/]*)
132 /mnt(/[^/]*)?
133 /rhev(/[^/]*)?
134 /media(/[^/]*)
135 /media(/[^/]*)?
136 /etc/rhgb(/.*)?
137 /media/.hal-.*
138 /net
139 /afs
140 /rhev
141 /misc
142 postfix_var_run_t
144 /var/spool/postfix/pid/.*
146 tmp_t
148 /tmp
150 /usr/tmp
151 /var/tmp
152 /tmp-inst
153 /var/tmp-inst
154 /var/tmp/vi.recover

158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux postfix_showq policy is very flexible allowing users to setup
165 their postfix_showq processes in as secure a method as possible.
166 The following file types are defined for postfix_showq:
168 postfix_showq_exec_t
172 - Set files with the postfix_showq_exec_t type, if you want to transi‐
174 tion an executable to the postfix_showq_t domain.
175 Note: File context can be temporarily modified with the chcon command.
179 If you want to permanently change the file context you need to use the
180 semanage fcontext command. This will modify the SELinux labeling data‐
181 base. You will need to use restorecon to apply the labels.
182
185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
