6 setfiles_selinux - Security Enhanced Linux Policy for the setfiles pro‐
7 cesses
8
10 Security-Enhanced Linux secures the setfiles processes via flexible
11 mandatory access control.
12 The setfiles processes execute with the setfiles_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 setfiles_t
20
24 The setfiles_t SELinux type can be entered via the setfiles_exec_t file
25 type.
26 The default entrypoint paths for the setfiles_t domain are the follow‐
28 ing:
29 /sbin/setfiles.*, /usr/sbin/setfiles.*, /sbin/restorecon,
31 /usr/sbin/restorecon
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 setfiles policy is very flexible allowing users to setup their setfiles
41 processes in as secure a method as possible.
42 The following process types are defined for setfiles:
44 setfiles_t, setfiles_mac_t
46 Note: semanage permissive -a setfiles_t can be used to make the process
48 type setfiles_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
54 SELinux policy is customizable based on least access required. set‐
55 files policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run setfiles with the tightest access
57 possible.
58 If you want to allow system cron jobs to relabel filesystem for restor‐
62 ing file contexts, you must turn on the cron_can_relabel boolean. Dis‐
63 abled by default.
64 setsebool -P cron_can_relabel 1
66 If you want to allow all daemons the ability to read/write terminals,
70 you must turn on the daemons_use_tty boolean. Disabled by default.
71 setsebool -P daemons_use_tty 1
73 If you want to deny any process from ptracing or debugging any other
77 processes, you must turn on the deny_ptrace boolean. Enabled by
78 default.
79 setsebool -P deny_ptrace 1
81 If you want to allow any process to mmap any file on system with
85 attribute file_type, you must turn on the domain_can_mmap_files bool‐
86 ean. Enabled by default.
87 setsebool -P domain_can_mmap_files 1
89 If you want to allow all domains write to kmsg_device, while kernel is
93 executed with systemd.log_target=kmsg parameter, you must turn on the
94 domain_can_write_kmsg boolean. Disabled by default.
95 setsebool -P domain_can_write_kmsg 1
97 If you want to allow all domains to use other domains file descriptors,
101 you must turn on the domain_fd_use boolean. Enabled by default.
102 setsebool -P domain_fd_use 1
104 If you want to allow all domains to have the kernel load modules, you
108 must turn on the domain_kernel_load_modules boolean. Disabled by
109 default.
110 setsebool -P domain_kernel_load_modules 1
112 If you want to allow all domains to execute in fips_mode, you must turn
116 on the fips_mode boolean. Enabled by default.
117 setsebool -P fips_mode 1
119 If you want to enable reading of urandom for all domains, you must turn
123 on the global_ssp boolean. Disabled by default.
124 setsebool -P global_ssp 1
126 If you want to enable polyinstantiated directory support, you must turn
130 on the polyinstantiation_enabled boolean. Disabled by default.
131 setsebool -P polyinstantiation_enabled 1
133
137 The SELinux process type setfiles_t can manage files labeled with the
138 following file types. The paths listed are the default paths for these
139 file types. Note the processes UID still need to have DAC permissions.
140 security_t
142 /selinux
144 user_home_type
146 all user home files
148
151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux setfiles policy is very flexible allowing users to setup their
158 setfiles processes in as secure a method as possible.
159 The following file types are defined for setfiles:
161 setfiles_exec_t
165 - Set files with the setfiles_exec_t type, if you want to transition an
167 executable to the setfiles_t domain.
168 Paths:
171 /sbin/setfiles.*, /usr/sbin/setfiles.*, /sbin/restorecon,
172 /usr/sbin/restorecon
173 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190 semanage boolean can also be used to manipulate the booleans
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
