6 qmail_lspawn_selinux - Security Enhanced Linux Policy for the
7 qmail_lspawn processes
8
10 Security-Enhanced Linux secures the qmail_lspawn processes via flexible
11 mandatory access control.
12 The qmail_lspawn processes execute with the qmail_lspawn_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_lspawn_t
20
24 The qmail_lspawn_t SELinux type can be entered via the
25 qmail_lspawn_exec_t file type.
26 The default entrypoint paths for the qmail_lspawn_t domain are the fol‐
28 lowing:
29 /var/qmail/bin/qmail-lspawn
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_lspawn policy is very flexible allowing users to setup their
40 qmail_lspawn processes in as secure a method as possible.
41 The following process types are defined for qmail_lspawn:
43 qmail_lspawn_t
45 Note: semanage permissive -a qmail_lspawn_t can be used to make the
47 process type qmail_lspawn_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_lspawn policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run qmail_lspawn 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 sysadm to debug or ptrace all processes, you must
68 turn on the allow_ptrace boolean. Disabled by default.
69 setsebool -P allow_ptrace 1
71 If you want to allow all domains to have the kernel load modules, you
75 must turn on the domain_kernel_load_modules boolean. Disabled by
76 default.
77 setsebool -P domain_kernel_load_modules 1
79 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84 setsebool -P fips_mode 1
86 If you want to enable reading of urandom for all domains, you must turn
90 on the global_ssp boolean. Disabled by default.
91 setsebool -P global_ssp 1
93 If you want to support NFS home directories, you must turn on the
97 use_nfs_home_dirs boolean. Disabled by default.
98 setsebool -P use_nfs_home_dirs 1
100 If you want to support SAMBA home directories, you must turn on the
104 use_samba_home_dirs boolean. Disabled by default.
105 setsebool -P use_samba_home_dirs 1

111 The SELinux process type qmail_lspawn_t can manage files labeled with
112 the following file types. The paths listed are the default paths for
113 these file types. Note the processes UID still need to have DAC per‐
114 missions.
115 cifs_t
117 dovecot_spool_t
120 /var/spool/dovecot(/.*)?
122 initrc_tmp_t

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