6 ipmievd_helper_selinux - Security Enhanced Linux Policy for the
7 ipmievd_helper processes
8
10 Security-Enhanced Linux secures the ipmievd_helper processes via flexi‐
11 ble mandatory access control.
12
13 The ipmievd_helper processes execute with the ipmievd_helper_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep ipmievd_helper_t
20
21
22
24 The ipmievd_helper_t SELinux type can be entered via the
25 ipmievd_helper_exec_t file type.
26
27 The default entrypoint paths for the ipmievd_helper_t domain are the
28 following:
29
30 /usr/libexec/openipmi-helper
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 ipmievd_helper policy is very flexible allowing users to setup their
40 ipmievd_helper processes in as secure a method as possible.
41
42 The following process types are defined for ipmievd_helper:
43
44 ipmievd_helper_t
45
46 Note: semanage permissive -a ipmievd_helper_t can be used to make the
47 process type ipmievd_helper_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 ipmievd_helper policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run ipmievd_helper with the
56 tightest access possible.
57
58
59
60 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. Enabled by default.
64
65 setsebool -P deny_execmem 1
66
67
68
69 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71
72 setsebool -P fips_mode 1
73
74
75
76 If you want to control the ability to mmap a low area of the address
77 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
78 the mmap_low_allowed boolean. Disabled by default.
79
80 setsebool -P mmap_low_allowed 1
81
82
83
84 If you want to disable kernel module loading, you must turn on the
85 secure_mode_insmod boolean. Enabled by default.
86
87 setsebool -P secure_mode_insmod 1
88
89
90
91 If you want to allow unconfined executables to make their heap memory
92 executable. Doing this is a really bad idea. Probably indicates a
93 badly coded executable, but could indicate an attack. This executable
94 should be reported in bugzilla, you must turn on the selin‐
95 uxuser_execheap boolean. Disabled by default.
96
97 setsebool -P selinuxuser_execheap 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 selinuxuser_exec‐
105 stack boolean. Disabled by default.
106
107 setsebool -P selinuxuser_execstack 1
108

112 The SELinux process type ipmievd_helper_t can manage files labeled with
113 the following file types. The paths listed are the default paths for
114 these file types. Note the processes UID still need to have DAC per‐
115 missions.
116
117 file_type
118
119 all files on the system
120
121
123 SELinux requires files to have an extended attribute to define the file
124 type.
125
126 You can see the context of a file using the -Z option to ls
127
128 Policy governs the access confined processes have to these files.
129 SELinux ipmievd_helper policy is very flexible allowing users to setup
130 their ipmievd_helper processes in as secure a method as possible.
131
132 The following file types are defined for ipmievd_helper:
133
134
135
136 ipmievd_helper_exec_t
137
138 - Set files with the ipmievd_helper_exec_t type, if you want to transi‐
139 tion an executable to the ipmievd_helper_t domain.
140
141
142
143 Note: File context can be temporarily modified with the chcon command.
144 If you want to permanently change the file context you need to use the
145 semanage fcontext command. This will modify the SELinux labeling data‐
146 base. You will need to use restorecon to apply the labels.
147
148
150 semanage fcontext can also be used to manipulate default file context
151 mappings.
152
153 semanage permissive can also be used to manipulate whether or not a
154 process type is permissive.
155
156 semanage module can also be used to enable/disable/install/remove pol‐
157 icy modules.
158
159 semanage boolean can also be used to manipulate the booleans
160
161
162 system-config-selinux is a GUI tool available to customize SELinux pol‐
163 icy settings.
