6 qmail_local_selinux - Security Enhanced Linux Policy for the
7 qmail_local processes
8
10 Security-Enhanced Linux secures the qmail_local processes via flexible
11 mandatory access control.
12 The qmail_local processes execute with the qmail_local_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_local_t
20
24 The qmail_local_t SELinux type can be entered via the
25 qmail_local_exec_t file type.
26 The default entrypoint paths for the qmail_local_t domain are the fol‐
28 lowing:
29 /var/qmail/bin/qmail-local
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_local policy is very flexible allowing users to setup their
40 qmail_local processes in as secure a method as possible.
41 The following process types are defined for qmail_local:
43 qmail_local_t
45 Note: semanage permissive -a qmail_local_t can be used to make the
47 process type qmail_local_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_local policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_local with the tight‐
56 est 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
114 If you want to support NFS home directories, you must turn on the
118 use_nfs_home_dirs boolean. Disabled by default.
119 setsebool -P use_nfs_home_dirs 1
121 If you want to support SAMBA home directories, you must turn on the
125 use_samba_home_dirs boolean. Disabled by default.
126 setsebool -P use_samba_home_dirs 1
128
132 The SELinux process type qmail_local_t can manage files labeled with
133 the following file types. The paths listed are the default paths for
134 these file types. Note the processes UID still need to have DAC per‐
135 missions.
136 cifs_t
138 dovecot_spool_t
141 /var/spool/dovecot(/.*)?
143 initrc_tmp_t

150 /home/[^/]*/Maildir(/.*)?

152 mail_spool_t

197 SELinux requires files to have an extended attribute to define the file
198 type.
199 You can see the context of a file using the -Z option to ls
201 Policy governs the access confined processes have to these files.
203 SELinux qmail_local policy is very flexible allowing users to setup
204 their qmail_local processes in as secure a method as possible.
205 The following file types are defined for qmail_local:
207 qmail_local_exec_t
211 - Set files with the qmail_local_exec_t type, if you want to transition
213 an executable to the qmail_local_t domain.
214 Note: File context can be temporarily modified with the chcon command.
218 If you want to permanently change the file context you need to use the
219 semanage fcontext command. This will modify the SELinux labeling data‐
220 base. You will need to use restorecon to apply the labels.
221
224 semanage fcontext can also be used to manipulate default file context
225 mappings.
226 semanage permissive can also be used to manipulate whether or not a
228 process type is permissive.
229 semanage module can also be used to enable/disable/install/remove pol‐
231 icy modules.
232 semanage boolean can also be used to manipulate the booleans
234 system-config-selinux is a GUI tool available to customize SELinux pol‐
237 icy settings.
