6 tmpreaper_selinux - Security Enhanced Linux Policy for the tmpreaper
7 processes
8
10 Security-Enhanced Linux secures the tmpreaper processes via flexible
11 mandatory access control.
12 The tmpreaper processes execute with the tmpreaper_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep tmpreaper_t
20
24 The tmpreaper_t SELinux type can be entered via the tmpreaper_exec_t
25 file type.
26 The default entrypoint paths for the tmpreaper_t domain are the follow‐
28 ing:
29 /usr/sbin/tmpwatch, /usr/sbin/tmpreaper, /etc/rc.d/init.d/mountall-
31 bootclean.sh, /etc/rc.d/init.d/mountnfs-bootclean.sh
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 tmpreaper policy is very flexible allowing users to setup their
41 tmpreaper processes in as secure a method as possible.
42 The following process types are defined for tmpreaper:
44 tmpreaper_t
46 Note: semanage permissive -a tmpreaper_t can be used to make the
48 process type tmpreaper_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required.
55 tmpreaper policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run tmpreaper with the tightest
57 access possible.
58 If you want to determine whether tmpreaper can use cifs file systems,
62 you must turn on the tmpreaper_use_cifs boolean. Disabled by default.
63 setsebool -P tmpreaper_use_cifs 1
65 If you want to determine whether tmpreaper can use nfs file systems,
69 you must turn on the tmpreaper_use_nfs boolean. Disabled by default.
70 setsebool -P tmpreaper_use_nfs 1
72 If you want to determine whether tmpreaper can use samba_share files,
76 you must turn on the tmpreaper_use_samba boolean. Disabled by default.
77 setsebool -P tmpreaper_use_samba 1
79 If you want to allow users to resolve user passwd entries directly from
83 ldap rather then using a sssd server, you must turn on the authlo‐
84 gin_nsswitch_use_ldap boolean. Disabled by default.
85 setsebool -P authlogin_nsswitch_use_ldap 1
87 If you want to allow all domains to execute in fips_mode, you must turn
91 on the fips_mode boolean. Enabled by default.
92 setsebool -P fips_mode 1
94 If you want to allow confined applications to run with kerberos, you
98 must turn on the kerberos_enabled boolean. Enabled by default.
99 setsebool -P kerberos_enabled 1
101 If you want to allow system to run with NIS, you must turn on the
105 nis_enabled boolean. Disabled by default.
106 setsebool -P nis_enabled 1
108 If you want to allow confined applications to use nscd shared memory,
112 you must turn on the nscd_use_shm boolean. Enabled by default.
113 setsebool -P nscd_use_shm 1
115
119 The SELinux process type tmpreaper_t can manage files labeled with the
120 following file types. The paths listed are the default paths for these
121 file types. Note the processes UID still need to have DAC permissions.

160 SELinux requires files to have an extended attribute to define the file
161 type.
162 You can see the context of a file using the -Z option to ls
164 Policy governs the access confined processes have to these files.
166 SELinux tmpreaper policy is very flexible allowing users to setup their
167 tmpreaper processes in as secure a method as possible.
168 The following file types are defined for tmpreaper:
170 tmpreaper_exec_t
174 - Set files with the tmpreaper_exec_t type, if you want to transition
176 an executable to the tmpreaper_t domain.
177 Paths:
180 /usr/sbin/tmpwatch, /usr/sbin/tmpreaper, /etc/rc.d/init.d/moun‐
181 tall-bootclean.sh, /etc/rc.d/init.d/mountnfs-bootclean.sh
182 Note: File context can be temporarily modified with the chcon command.
185 If you want to permanently change the file context you need to use the
186 semanage fcontext command. This will modify the SELinux labeling data‐
187 base. You will need to use restorecon to apply the labels.
188
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199 semanage boolean can also be used to manipulate the booleans
201 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
