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, /usr/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 dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72
76 The SELinux process type cachefilesd_t can manage files labeled with
77 the following file types. The paths listed are the default paths for
78 these file types. Note the processes UID still need to have DAC per‐
79 missions.

128 SELinux requires files to have an extended attribute to define the file
129 type.
130 You can see the context of a file using the -Z option to ls
132 Policy governs the access confined processes have to these files.
134 SELinux cachefilesd policy is very flexible allowing users to setup
135 their cachefilesd processes in as secure a method as possible.
136 STANDARD FILE CONTEXT
138 SELinux defines the file context types for the cachefilesd, if you
140 wanted to store files with these types in a different paths, you need
141 to execute the semanage command to specify alternate labeling and then
142 use restorecon to put the labels on disk.
143 semanage fcontext -a -t cachefilesd_exec_t '/srv/cachefilesd/con‐
145 tent(/.*)?'
146 restorecon -R -v /srv/mycachefilesd_content
147 Note: SELinux often uses regular expressions to specify labels that
149 match multiple files.
150 The following file types are defined for cachefilesd:
152 cachefilesd_exec_t
156 - Set files with the cachefilesd_exec_t type, if you want to transition
158 an executable to the cachefilesd_t domain.
159 Paths:
162 /sbin/cachefilesd, /usr/sbin/cachefilesd
163 cachefilesd_var_run_t
166 - Set files with the cachefilesd_var_run_t type, if you want to store
168 the cachefilesd files under the /run or /var/run directory.
169 Note: File context can be temporarily modified with the chcon command.
173 If you want to permanently change the file context you need to use the
174 semanage fcontext command. This will modify the SELinux labeling data‐
175 base. You will need to use restorecon to apply the labels.
176
179 semanage fcontext can also be used to manipulate default file context
180 mappings.
181 semanage permissive can also be used to manipulate whether or not a
183 process type is permissive.
184 semanage module can also be used to enable/disable/install/remove pol‐
186 icy modules.
187 semanage boolean can also be used to manipulate the booleans
189 system-config-selinux is a GUI tool available to customize SELinux pol‐
192 icy settings.
