6 gnome_initial_setup_selinux - Security Enhanced Linux Policy for the
7 gnome_initial_setup processes
8
10 Security-Enhanced Linux secures the gnome_initial_setup processes via
11 flexible mandatory access control.
12 The gnome_initial_setup processes execute with the gnome_ini‐
14 tial_setup_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep gnome_initial_setup_t
20
24 The gnome_initial_setup_t SELinux type can be entered via the
25 gnome_initial_setup_exec_t file type.
26 The default entrypoint paths for the gnome_initial_setup_t domain are
28 the following:
29 /usr/libexec/gnome-initial-setup.*
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 gnome_initial_setup policy is very flexible allowing users to setup
40 their gnome_initial_setup processes in as secure a method as possible.
41 The following process types are defined for gnome_initial_setup:
43 gnome_initial_setup_t
45 Note: semanage permissive -a gnome_initial_setup_t can be used to make
47 the process type gnome_initial_setup_t permissive. SELinux does not
48 deny access to permissive process types, but the AVC (SELinux denials)
49 messages are still generated.
50
53 SELinux policy is customizable based on least access required.
54 gnome_initial_setup policy is extremely flexible and has several bool‐
55 eans that allow you to manipulate the policy and run gnome_ini‐
56 tial_setup with the tightest access possible.
57 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Disabled by default.
64 setsebool -P deny_execmem 1
66 If you want to control the ability to mmap a low area of the address
70 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
71 the mmap_low_allowed boolean. Disabled by default.
72 setsebool -P mmap_low_allowed 1
74 If you want to disable kernel module loading, you must turn on the se‐
78 cure_mode_insmod boolean. Disabled by default.
79 setsebool -P secure_mode_insmod 1
81 If you want to allow unconfined executables to make their heap memory
85 executable. Doing this is a really bad idea. Probably indicates a
86 badly coded executable, but could indicate an attack. This executable
87 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
88 echeap boolean. Disabled by default.
89 setsebool -P selinuxuser_execheap 1
91 If you want to allow unconfined executables to make their stack exe‐
95 cutable. This should never, ever be necessary. Probably indicates a
96 badly coded executable, but could indicate an attack. This executable
97 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
98 stack boolean. Enabled by default.
99 setsebool -P selinuxuser_execstack 1

105 The SELinux process type gnome_initial_setup_t can manage files labeled
106 with the following file types. The paths listed are the default paths
107 for these file types. Note the processes UID still need to have DAC
108 permissions.
109 file_type
111 all files on the system
113
116 SELinux requires files to have an extended attribute to define the file
117 type.
118 You can see the context of a file using the -Z option to ls
120 Policy governs the access confined processes have to these files.
122 SELinux gnome_initial_setup policy is very flexible allowing users to
123 setup their gnome_initial_setup processes in as secure a method as pos‐
124 sible.
125 STANDARD FILE CONTEXT
127 SELinux defines the file context types for the gnome_initial_setup, if
129 you wanted to store files with these types in a different paths, you
130 need to execute the semanage command to specify alternate labeling and
131 then use restorecon to put the labels on disk.
132 semanage fcontext -a -t gnome_initial_setup_exec_t '/srv/gnome_ini‐
134 tial_setup/content(/.*)?'
135 restorecon -R -v /srv/mygnome_initial_setup_content
136 Note: SELinux often uses regular expressions to specify labels that
138 match multiple files.
139 The following file types are defined for gnome_initial_setup:
141 gnome_initial_setup_exec_t
145 - Set files with the gnome_initial_setup_exec_t type, if you want to
147 transition an executable to the gnome_initial_setup_t domain.
148 gnome_initial_setup_var_lib_t
152 - Set files with the gnome_initial_setup_var_lib_t type, if you want to
154 store the gnome initial setup files under the /var/lib directory.
155 gnome_initial_setup_var_run_t
159 - Set files with the gnome_initial_setup_var_run_t type, if you want to
161 store the gnome initial setup files under the /run or /var/run direc‐
162 tory.
163 Note: File context can be temporarily modified with the chcon command.
167 If you want to permanently change the file context you need to use the
168 semanage fcontext command. This will modify the SELinux labeling data‐
169 base. You will need to use restorecon to apply the labels.
170
173 semanage fcontext can also be used to manipulate default file context
174 mappings.
175 semanage permissive can also be used to manipulate whether or not a
177 process type is permissive.
178 semanage module can also be used to enable/disable/install/remove pol‐
180 icy modules.
181 semanage boolean can also be used to manipulate the booleans
183 system-config-selinux is a GUI tool available to customize SELinux pol‐
186 icy settings.
