6 setfiles_mac_selinux - Security Enhanced Linux Policy for the set‐
7 files_mac processes
8
10 Security-Enhanced Linux secures the setfiles_mac processes via flexible
11 mandatory access control.
12 The setfiles_mac processes execute with the setfiles_mac_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep setfiles_mac_t
20
24 The setfiles_mac_t SELinux type can be entered via the setfiles_exec_t,
25 file_type, unlabeled_t, proc_type, filesystem_type, mtrr_device_t,
26 sysctl_type file types.
27 The default entrypoint paths for the setfiles_mac_t domain are the fol‐
29 lowing:
30 /sbin/setfiles.*, /usr/sbin/setfiles.*, /sbin/restorecon, all files on
32 the system, /dev/cpu/mtrr
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 setfiles_mac policy is very flexible allowing users to setup their set‐
42 files_mac processes in as secure a method as possible.
43 The following process types are defined for setfiles_mac:
45 setfiles_mac_t
47 Note: semanage permissive -a setfiles_mac_t can be used to make the
49 process type setfiles_mac_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required. set‐
56 files_mac policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run setfiles_mac with the tight‐
58 est access possible.
59 If you want to allow all domains to use other domains file descriptors,
63 you must turn on the allow_domain_fd_use boolean. Enabled by default.
64 setsebool -P allow_domain_fd_use 1
66 If you want to allow unconfined executables to make their heap memory
70 executable. Doing this is a really bad idea. Probably indicates a
71 badly coded executable, but could indicate an attack. This executable
72 should be reported in bugzilla, you must turn on the allow_execheap
73 boolean. Disabled by default.
74 setsebool -P allow_execheap 1
76 If you want to allow unconfined executables to map a memory region as
80 both executable and writable, this is dangerous and the executable
81 should be reported in bugzilla), you must turn on the allow_execmem
82 boolean. Enabled by default.
83 setsebool -P allow_execmem 1
85 If you want to allow all unconfined executables to use libraries
89 requiring text relocation that are not labeled textrel_shlib_t), you
90 must turn on the allow_execmod boolean. Enabled by default.
91 setsebool -P allow_execmod 1
93 If you want to allow unconfined executables to make their stack exe‐
97 cutable. This should never, ever be necessary. Probably indicates a
98 badly coded executable, but could indicate an attack. This executable
99 should be reported in bugzilla), you must turn on the allow_execstack
100 boolean. Enabled by default.
101 setsebool -P allow_execstack 1
103 If you want to allow sysadm to debug or ptrace all processes, you must
107 turn on the allow_ptrace boolean. Disabled by default.
108 setsebool -P allow_ptrace 1
110 If you want to allow all domains to have the kernel load modules, you
114 must turn on the domain_kernel_load_modules boolean. Disabled by
115 default.
116 setsebool -P domain_kernel_load_modules 1
118 If you want to allow all domains to execute in fips_mode, you must turn
122 on the fips_mode boolean. Enabled by default.
123 setsebool -P fips_mode 1
125 If you want to enable reading of urandom for all domains, you must turn
129 on the global_ssp boolean. Disabled by default.
130 setsebool -P global_ssp 1
132 If you want to allow certain domains to map low memory in the kernel,
136 you must turn on the mmap_low_allowed boolean. Disabled by default.
137 setsebool -P mmap_low_allowed 1
139 If you want to boolean to determine whether the system permits loading
143 policy, setting enforcing mode, and changing boolean values. Set this
144 to true and you have to reboot to set it back, you must turn on the
145 secure_mode_policyload boolean. Disabled by default.
146 setsebool -P secure_mode_policyload 1
148 If you want to support X userspace object manager, you must turn on the
152 xserver_object_manager boolean. Disabled by default.
153 setsebool -P xserver_object_manager 1
155
159 The SELinux process type setfiles_mac_t can manage files labeled with
160 the following file types. The paths listed are the default paths for
161 these file types. Note the processes UID still need to have DAC per‐
162 missions.
163 file_type
165 all files on the system
167
170 semanage fcontext can also be used to manipulate default file context
171 mappings.
172 semanage permissive can also be used to manipulate whether or not a
174 process type is permissive.
175 semanage module can also be used to enable/disable/install/remove pol‐
177 icy modules.
178 semanage boolean can also be used to manipulate the booleans
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
183 icy settings.
