6 cachefilesd_selinux - Security Enhanced Linux Policy for the
7 cachefilesd processes
8
10 Security-Enhanced Linux secures the cachefilesd processes via flexible
11 mandatory access control.
12 The cachefilesd processes execute with the cachefilesd_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 cachefilesd_t
20
24 The cachefilesd_t SELinux type can be entered via the
25 cachefilesd_exec_t file type.
26 The default entrypoint paths for the cachefilesd_t domain are the fol‐
28 lowing:
29 /sbin/cachefilesd
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 cachefilesd policy is very flexible allowing users to setup their
40 cachefilesd processes in as secure a method as possible.
41 The following process types are defined for cachefilesd:
43 cachefilesd_t, cachefiles_kernel_t
45 Note: semanage permissive -a cachefilesd_t can be used to make the
47 process type cachefilesd_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 cachefilesd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run cachefilesd with the tight‐
56 est access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.

71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1
86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to enable cluster mode for daemons, you must turn on the
97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type cachefilesd_t can manage files labeled with
134 the following file types. The paths listed are the default paths for
135 these file types. Note the processes UID still need to have DAC per‐
136 missions.

201 SELinux requires files to have an extended attribute to define the file
202 type.
203 You can see the context of a file using the -Z option to ls
205 Policy governs the access confined processes have to these files.
207 SELinux cachefilesd policy is very flexible allowing users to setup
208 their cachefilesd processes in as secure a method as possible.
209 STANDARD FILE CONTEXT
211 SELinux defines the file context types for the cachefilesd, if you
213 wanted to store files with these types in a diffent paths, you need to
214 execute the semanage command to sepecify alternate labeling and then
215 use restorecon to put the labels on disk.
216 semanage fcontext -a -t cachefilesd_var_run_t '/srv/mycachefilesd_con‐
218 tent(/.*)?'
219 restorecon -R -v /srv/mycachefilesd_content
220 Note: SELinux often uses regular expressions to specify labels that
222 match multiple files.
223 The following file types are defined for cachefilesd:
225 cachefilesd_exec_t
229 - Set files with the cachefilesd_exec_t type, if you want to transition
231 an executable to the cachefilesd_t domain.
232 cachefilesd_var_run_t
236 - Set files with the cachefilesd_var_run_t type, if you want to store
238 the cachefilesd files under the /run or /var/run directory.
239 Note: File context can be temporarily modified with the chcon command.
243 If you want to permanently change the file context you need to use the
244 semanage fcontext command. This will modify the SELinux labeling data‐
245 base. You will need to use restorecon to apply the labels.
246
249 semanage fcontext can also be used to manipulate default file context
250 mappings.
251 semanage permissive can also be used to manipulate whether or not a
253 process type is permissive.
254 semanage module can also be used to enable/disable/install/remove pol‐
256 icy modules.
257 semanage boolean can also be used to manipulate the booleans
259 system-config-selinux is a GUI tool available to customize SELinux pol‐
262 icy settings.
