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 allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 The SELinux process type cachefilesd_t can manage files labeled with
69 the following file types. The paths listed are the default paths for
70 these file types. Note the processes UID still need to have DAC per‐
71 missions.

120 SELinux requires files to have an extended attribute to define the file
121 type.
122 You can see the context of a file using the -Z option to ls
124 Policy governs the access confined processes have to these files.
126 SELinux cachefilesd policy is very flexible allowing users to setup
127 their cachefilesd processes in as secure a method as possible.
128 STANDARD FILE CONTEXT
130 SELinux defines the file context types for the cachefilesd, if you
132 wanted to store files with these types in a diffent paths, you need to
133 execute the semanage command to specify alternate labeling and then use
134 restorecon to put the labels on disk.
135 semanage fcontext -a -t cachefilesd_var_run_t '/srv/mycachefilesd_con‐
137 tent(/.*)?'
138 restorecon -R -v /srv/mycachefilesd_content
139 Note: SELinux often uses regular expressions to specify labels that
141 match multiple files.
142 The following file types are defined for cachefilesd:
144 cachefilesd_exec_t
148 - Set files with the cachefilesd_exec_t type, if you want to transition
150 an executable to the cachefilesd_t domain.
151 Paths:
154 /sbin/cachefilesd, /usr/sbin/cachefilesd
155 cachefilesd_var_run_t
158 - Set files with the cachefilesd_var_run_t type, if you want to store
160 the cachefilesd files under the /run or /var/run directory.
161 Note: File context can be temporarily modified with the chcon command.
165 If you want to permanently change the file context you need to use the
166 semanage fcontext command. This will modify the SELinux labeling data‐
167 base. You will need to use restorecon to apply the labels.
168
171 semanage fcontext can also be used to manipulate default file context
172 mappings.
173 semanage permissive can also be used to manipulate whether or not a
175 process type is permissive.
176 semanage module can also be used to enable/disable/install/remove pol‐
178 icy modules.
179 semanage boolean can also be used to manipulate the booleans
181 system-config-selinux is a GUI tool available to customize SELinux pol‐
184 icy settings.
