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
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 setfiles policy is very flexible allowing users to setup their setfiles
40 processes in as secure a method as possible.
41 The following process types are defined for setfiles:
43 setfiles_mac_t, setfiles_t
45 Note: semanage permissive -a setfiles_t can be used to make the process
47 type setfiles_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. set‐
54 files policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run setfiles with the tightest access
56 possible.
57 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to enable polyinstantiated directory support, you must turn
76 on the allow_polyinstantiation boolean. Enabled by default.
77 setsebool -P allow_polyinstantiation 1
79 If you want to allow sysadm to debug or ptrace all processes, you must
83 turn on the allow_ptrace boolean. Disabled by default.
84 setsebool -P allow_ptrace 1
86 If you want to allow system cron jobs to relabel filesystem for restor‐
90 ing file contexts, you must turn on the cron_can_relabel boolean. Dis‐
91 abled by default.
92 setsebool -P cron_can_relabel 1
94 If you want to allow all domains to have the kernel load modules, you
98 must turn on the domain_kernel_load_modules boolean. Disabled by
99 default.
100 setsebool -P domain_kernel_load_modules 1
102 If you want to allow all domains to execute in fips_mode, you must turn
106 on the fips_mode boolean. Enabled by default.
107 setsebool -P fips_mode 1
109 If you want to enable reading of urandom for all domains, you must turn
113 on the global_ssp boolean. Disabled by default.
114 setsebool -P global_ssp 1
116
120 The SELinux process type setfiles_t can manage files labeled with the
121 following file types. The paths listed are the default paths for these
122 file types. Note the processes UID still need to have DAC permissions.
123 initrc_tmp_t
125 mnt_t
128 /mnt(/[^/]*)
130 /mnt(/[^/]*)?
131 /rhev(/[^/]*)?
132 /media(/[^/]*)
133 /media(/[^/]*)?
134 /etc/rhgb(/.*)?
135 /media/.hal-.*
136 /net
137 /afs
138 /rhev
139 /misc
140 security_t
142 tmp_t
145 /tmp
147 /usr/tmp
148 /var/tmp
149 /tmp-inst
150 /var/tmp-inst
151 /var/tmp/vi.recover

155 SELinux requires files to have an extended attribute to define the file
156 type.
157 You can see the context of a file using the -Z option to ls
159 Policy governs the access confined processes have to these files.
161 SELinux setfiles policy is very flexible allowing users to setup their
162 setfiles processes in as secure a method as possible.
163 The following file types are defined for setfiles:
165 setfiles_exec_t
169 - Set files with the setfiles_exec_t type, if you want to transition an
171 executable to the setfiles_t domain.
172 Paths:
175 /sbin/setfiles.*, /usr/sbin/setfiles.*, /sbin/restorecon
176 Note: File context can be temporarily modified with the chcon command.
179 If you want to permanently change the file context you need to use the
180 semanage fcontext command. This will modify the SELinux labeling data‐
181 base. You will need to use restorecon to apply the labels.
182
185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
