6 semanage.conf - global configuration file for the SELinux Management
7 library
8
10 The semanage.conf file is usually located under the directory
11 /etc/selinux and it is used for run-time configuration of the behavior
12 of the SELinux Management library.
13 Each line should contain a configuration parameter followed by the
16 equal sign ("=") and then followed by the configuration value for that
17 parameter. Anything after the "#" symbol is ignored similarly to empty
18 lines.
19 The following parameters are allowed:
22 module-store
25 Specify how the SELinux Management library should inter‐
26 act with the SELinux policy store. When set to "direct",
27 the SELinux Management library writes to the SELinux pol‐
28 icy module store directly (this is the default setting).
29 Otherwise a socket path or a server name can be used for
30 the argument. If the argument begins with "/" (as in
31 "/foo/bar"), it represents the path to a named socket
32 that should be used to connect the policy management
33 server. If the argument does not begin with a "/" (as in
34 "foo.com:4242"), it should be interpreted as the name of
35 a remote policy management server to be used through a
36 TCP connection (default port is 4242 unless a different
37 one is specified after the server name using the colon to
38 separate the two fields).
39 root Specify an alternative root path to use for the store.
42 The default is "/"
43 store-root
46 Specify an alternative store_root path to use. The
47 default is "/var/lib/selinux"
48 compiler-directory
51 Specify an alternative directory that contains HLL to CIL
52 compilers. The default value is
53 "/usr/libexec/selinux/hll".
54 ignore-module-cache
57 Whether or not to ignore the cache of CIL modules com‐
58 piled from HLL. It can be set to either "true" or "false"
59 and is set to "false" by default. If the cache is
60 ignored, then all CIL modules are recompiled from their
61 HLL modules.
62 policy-version
65 When generating the policy, by default semanage will set
66 the policy version to POLICYDB_VERSION_MAX, as defined in
67 <sepol/policydb/policydb.h>. Change this setting if a
68 different version needs to be set for the policy.
69 target-platform
72 The target platform to generate policies for. Valid val‐
73 ues are "selinux" and "xen", and is set to "selinux" by
74 default.
75 expand-check
78 Whether or not to check "neverallow" rules when executing
79 all semanage command. It can be set to either "0" (dis‐
80 abled) or "1" (enabled) and by default it is enabled.
81 There might be a large penalty in execution time if this
82 option is enabled.
83 file-mode
86 By default the permission mode for the run-time policy
87 files is set to 0644.
88 save-previous
91 It controls whether the previous module directory is
92 saved after a successful commit to the policy store and
93 it can be set to either "true" or "false". By default it
94 is set to "false" (the previous version is deleted).
95 save-linked
98 It controls whether the previously linked module is saved
99 (with name "base.linked") after a successful commit to
100 the policy store. It can be set to either "true" or
101 "false" and by default it is set to "false" (the previous
102 module is deleted).
103 ignoredirs
106 List, separated by ";", of directories to ignore when
107 setting up users homedirs. Some distributions use this
108 to stop labeling /root as a homedir.
109 usepasswd
112 Whether or not to enable the use getpwent() to obtain a
113 list of home directories to label. It can be set to
114 either "true" or "false". By default it is set to
115 "true".
116 disable-genhomedircon
119 It controls whether or not the genhomedircon function is
120 executed when using the semanage command and it can be
121 set to either "false" or "true". By default the genhome‐
122 dircon functionality is enabled (equivalent to this
123 option set to "false").
124 handle-unknown
127 This option overrides the kernel behavior for handling
128 permissions defined in the kernel but missing from the
129 actual policy. It can be set to "deny", "reject" or
130 "allow". By default the setting from the policy is taken.
131 bzip-blocksize
134 It should be in the range 0-9. A value of 0 means no com‐
135 pression. By default the bzip block size is set to 9
136 (actual block size value is obtained after multiplication
137 by 100000).
138 bzip-small
141 When set to "true", the bzip algorithm shall try to
142 reduce its system memory usage. It can be set to either
143 "true" or "false" and by default it is set to "false".
144 remove-hll
147 When set to "true", HLL files will be removed after com‐
148 pilation into CIL. In order to delete HLL files already
149 compiled into CIL, modules will need to be recompiled
150 with the ignore-module-cache option set to 'true' or
151 using the ignore-module-cache option with semodule. The
152 remove-hll option can be set to either "true" or "false"
153 and by default it is set to "false".
154 Please note that since this option deletes all HLL files,
156 an updated HLL compiler will not be able to recompile the
157 original HLL file into CIL. In order to compile the
158 original HLL file into CIL, the same HLL file will need
159 to be reinstalled.
160 optimize-policy
163 When set to "true", the kernel policy will be optimized
164 upon rebuilds. It can be set to either "true" or "false"
165 and by default it is set to "false".
