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
13 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
17 For example:
18
19 ps -eZ | grep cachefilesd_t
20
21
22
24 The cachefilesd_t SELinux type can be entered via the
25 cachefilesd_exec_t file type.
26
27 The default entrypoint paths for the cachefilesd_t domain are the fol‐
28 lowing:
29
30 /sbin/cachefilesd, /usr/sbin/cachefilesd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 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
42 The following process types are defined for cachefilesd:
43
44 cachefilesd_t, cachefiles_kernel_t
45
46 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
51
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
58
59
60 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
63 setsebool -P fips_mode 1
64
65
66
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.

119 SELinux requires files to have an extended attribute to define the file
120 type.
121
122 You can see the context of a file using the -Z option to ls
123
124 Policy governs the access confined processes have to these files.
125 SELinux cachefilesd policy is very flexible allowing users to setup
126 their cachefilesd processes in as secure a method as possible.
127
128 STANDARD FILE CONTEXT
129
130 SELinux defines the file context types for the cachefilesd, if you
131 wanted to store files with these types in a diffent paths, you need to
132 execute the semanage command to sepecify alternate labeling and then
133 use restorecon to put the labels on disk.
134
135 semanage fcontext -a -t cachefilesd_var_run_t '/srv/mycachefilesd_con‐
136 tent(/.*)?'
137 restorecon -R -v /srv/mycachefilesd_content
138
139 Note: SELinux often uses regular expressions to specify labels that
140 match multiple files.
141
142 The following file types are defined for cachefilesd:
143
144
145
146 cachefilesd_exec_t
147
148 - Set files with the cachefilesd_exec_t type, if you want to transition
149 an executable to the cachefilesd_t domain.
150
151
152 Paths:
153 /sbin/cachefilesd, /usr/sbin/cachefilesd
154
155
156 cachefilesd_var_run_t
157
158 - Set files with the cachefilesd_var_run_t type, if you want to store
159 the cachefilesd files under the /run or /var/run directory.
160
161
162
163 Note: File context can be temporarily modified with the chcon command.
164 If you want to permanently change the file context you need to use the
165 semanage fcontext command. This will modify the SELinux labeling data‐
166 base. You will need to use restorecon to apply the labels.
167
168
170 semanage fcontext can also be used to manipulate default file context
171 mappings.
172
173 semanage permissive can also be used to manipulate whether or not a
174 process type is permissive.
175
176 semanage module can also be used to enable/disable/install/remove pol‐
177 icy modules.
178
179 semanage boolean can also be used to manipulate the booleans
180
181
182 system-config-selinux is a GUI tool available to customize SELinux pol‐
183 icy settings.
