6 sandbox_x_client_selinux - Security Enhanced Linux Policy for the sand‐
7 box_x_client processes
8
10 Security-Enhanced Linux secures the sandbox_x_client processes via
11 flexible mandatory access control.
12
13 The sandbox_x_client processes execute with the sandbox_x_client_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sandbox_x_client_t
20
21
22
24 The sandbox_x_client_t SELinux type can be entered via the file_type,
25 sandbox_exec_t file types.
26
27 The default entrypoint paths for the sandbox_x_client_t domain are the
28 following:
29
30 all files on the system, /usr/share/sandbox/start
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 sandbox_x_client policy is very flexible allowing users to setup their
40 sandbox_x_client processes in as secure a method as possible.
41
42 The following process types are defined for sandbox_x_client:
43
44 sandbox_x_client_t
45
46 Note: semanage permissive -a sandbox_x_client_t can be used to make the
47 process type sandbox_x_client_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required. sand‐
54 box_x_client policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run sandbox_x_client with the
56 tightest access possible.

59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69
70 setsebool -P allow_kerberos 1
71
72
73
74 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76
77 setsebool -P allow_ptrace 1
78
79
80
81 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83
84 setsebool -P allow_ypbind 1
85
86
87
88 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91
92 setsebool -P domain_kernel_load_modules 1
93
94
95
96 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98
99 setsebool -P fips_mode 1
100
101
102
103 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105
106 setsebool -P global_ssp 1
107
108
109
110 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112
113 setsebool -P nscd_use_shm 1
114
115
116
117 If you want to support fusefs home directories, you must turn on the
118 use_fusefs_home_dirs boolean. Disabled by default.
119
120 setsebool -P use_fusefs_home_dirs 1
121
122
123
124 If you want to support NFS home directories, you must turn on the
125 use_nfs_home_dirs boolean. Disabled by default.
126
127 setsebool -P use_nfs_home_dirs 1
128
129
130
131 If you want to support SAMBA home directories, you must turn on the
132 use_samba_home_dirs boolean. Disabled by default.
133
134 setsebool -P use_samba_home_dirs 1
135
136
137
139 The SELinux process type sandbox_x_client_t can manage files labeled
140 with the following file types. The paths listed are the default paths
141 for these file types. Note the processes UID still need to have DAC
142 permissions.

190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192
193 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195
196 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198
199 semanage boolean can also be used to manipulate the booleans
