6 rpm_script_selinux - Security Enhanced Linux Policy for the rpm_script
7 processes
8
10 Security-Enhanced Linux secures the rpm_script processes via flexible
11 mandatory access control.
12
13 The rpm_script processes execute with the rpm_script_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep rpm_script_t
20
21
22
24 The rpm_script_t SELinux type can be entered via the file_type,
25 shell_exec_t, unlabeled_t, proc_type, filesystem_type, mtrr_device_t,
26 sysctl_type, bin_t file types.
27
28 The default entrypoint paths for the rpm_script_t domain are the fol‐
29 lowing:
30
31 All executeables with the default executable label, usually stored in
32 /usr/bin and /usr/sbin. all files on the system, /bin/d?ash,
33 /bin/zsh.*, /bin/ksh.*, /bin/sash, /bin/tcsh, /bin/yash, /bin/mksh,
34 /bin/fish, /bin/bash, /bin/bash2, /usr/bin/fish, /sbin/nologin,
35 /usr/sbin/sesh, /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh,
36 /usr/sbin/scponlyc, /usr/bin/git-shell, /usr/libexec/git-core/git-
37 shell, /dev/cpu/mtrr

40 SELinux defines process types (domains) for each process running on the
41 system
42
43 You can see the context of a process using the -Z option to ps
44
45 Policy governs the access confined processes have to files. SELinux
46 rpm_script policy is very flexible allowing users to setup their
47 rpm_script processes in as secure a method as possible.
48
49 The following process types are defined for rpm_script:
50
51 rpm_script_t
52
53 Note: semanage permissive -a rpm_script_t can be used to make the
54 process type rpm_script_t permissive. SELinux does not deny access to
55 permissive process types, but the AVC (SELinux denials) messages are
56 still generated.
57
58
60 SELinux policy is customizable based on least access required.
61 rpm_script policy is extremely flexible and has several booleans that
62 allow you to manipulate the policy and run rpm_script with the tightest
63 access possible.
64
65
66
67 If you want to allow all domains to use other domains file descriptors,
68 you must turn on the allow_domain_fd_use boolean. Enabled by default.
69
70 setsebool -P allow_domain_fd_use 1
71
72
73
74 If you want to allow unconfined executables to make their heap memory
75 executable. Doing this is a really bad idea. Probably indicates a
76 badly coded executable, but could indicate an attack. This executable
77 should be reported in bugzilla, you must turn on the allow_execheap
78 boolean. Disabled by default.
79
80 setsebool -P allow_execheap 1
81
82
83
84 If you want to allow unconfined executables to map a memory region as
85 both executable and writable, this is dangerous and the executable
86 should be reported in bugzilla), you must turn on the allow_execmem
87 boolean. Enabled by default.
88
89 setsebool -P allow_execmem 1
90
91
92
93 If you want to allow all unconfined executables to use libraries
94 requiring text relocation that are not labeled textrel_shlib_t), you
95 must turn on the allow_execmod boolean. Enabled by default.
96
97 setsebool -P allow_execmod 1
98
99
100
101 If you want to allow unconfined executables to make their stack exe‐
102 cutable. This should never, ever be necessary. Probably indicates a
103 badly coded executable, but could indicate an attack. This executable
104 should be reported in bugzilla), you must turn on the allow_execstack
105 boolean. Enabled by default.
106
107 setsebool -P allow_execstack 1
108
109
110
111 If you want to allow confined applications to run with kerberos, you
112 must turn on the allow_kerberos boolean. Enabled by default.
113
114 setsebool -P allow_kerberos 1
115
116
117
118 If you want to allow sysadm to debug or ptrace all processes, you must
119 turn on the allow_ptrace boolean. Disabled by default.
120
121 setsebool -P allow_ptrace 1
122
123
124
125 If you want to allow system to run with NIS, you must turn on the
126 allow_ypbind boolean. Disabled by default.
127
128 setsebool -P allow_ypbind 1
129
130
131
132 If you want to allow all domains to have the kernel load modules, you
133 must turn on the domain_kernel_load_modules boolean. Disabled by
134 default.
135
136 setsebool -P domain_kernel_load_modules 1
137
138
139
140 If you want to allow all domains to execute in fips_mode, you must turn
141 on the fips_mode boolean. Enabled by default.
142
143 setsebool -P fips_mode 1
144
145
146
147 If you want to enable reading of urandom for all domains, you must turn
148 on the global_ssp boolean. Disabled by default.
149
150 setsebool -P global_ssp 1
151
152
153
154 If you want to enable support for upstart as the init program, you must
155 turn on the init_upstart boolean. Enabled by default.
156
157 setsebool -P init_upstart 1
158
159
160
161 If you want to allow certain domains to map low memory in the kernel,
162 you must turn on the mmap_low_allowed boolean. Disabled by default.
163
164 setsebool -P mmap_low_allowed 1
165
166
167
168 If you want to allow confined applications to use nscd shared memory,
169 you must turn on the nscd_use_shm boolean. Enabled by default.
170
171 setsebool -P nscd_use_shm 1
172
173
174
175 If you want to disable transitions to insmod, you must turn on the
176 secure_mode_insmod boolean. Disabled by default.
177
178 setsebool -P secure_mode_insmod 1
179
180
181
182 If you want to boolean to determine whether the system permits loading
183 policy, setting enforcing mode, and changing boolean values. Set this
184 to true and you have to reboot to set it back, you must turn on the
185 secure_mode_policyload boolean. Disabled by default.
186
187 setsebool -P secure_mode_policyload 1
188
189

193
194 setsebool -P xserver_object_manager 1
195
196
197
199 The SELinux process type rpm_script_t can manage files labeled with the
200 following file types. The paths listed are the default paths for these
201 file types. Note the processes UID still need to have DAC permissions.
202
203 file_type
204
205 all files on the system
206
207
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211
212 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214
215 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
217
218 semanage boolean can also be used to manipulate the booleans
219
220
221 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
