7 cesses

10 Security-Enhanced Linux secures the ldconfig processes via flexible
11 mandatory access control.
12
13 The ldconfig processes execute with the ldconfig_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep ldconfig_t
20
21
22
24 The ldconfig_t SELinux type can be entered via the ldconfig_exec_t file
25 type.
26
27 The default entrypoint paths for the ldconfig_t domain are the follow‐
28 ing:
29
30 /sbin/sln, /usr/sbin/sln, /sbin/ldconfig, /usr/sbin/ldconfig
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 ldconfig policy is very flexible allowing users to setup their ldconfig
40 processes in as secure a method as possible.
41
42 The following process types are defined for ldconfig:
43
44 ldconfig_t
45
46 Note: semanage permissive -a ldconfig_t can be used to make the process
47 type ldconfig_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. ldcon‐
54 fig policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run ldconfig with the tightest access
56 possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to support NFS home directories, you must turn on the
68 use_nfs_home_dirs boolean. Enabled by default.
69
70 setsebool -P use_nfs_home_dirs 1
71
72
73
74 If you want to support SAMBA home directories, you must turn on the
75 use_samba_home_dirs boolean. Disabled by default.
76
77 setsebool -P use_samba_home_dirs 1
78
79
80
82 The SELinux process type ldconfig_t can manage files labeled with the
83 following file types. The paths listed are the default paths for these
84 file types. Note the processes UID still need to have DAC permissions.
85
86 ldconfig_cache_t
87
88 /var/cache/ldconfig(/.*)?
89
90 user_home_t
91
92 /home/[^/]+/.+
93
94
96 SELinux requires files to have an extended attribute to define the file
97 type.
98
99 You can see the context of a file using the -Z option to ls
100
101 Policy governs the access confined processes have to these files.
102 SELinux ldconfig policy is very flexible allowing users to setup their
103 ldconfig processes in as secure a method as possible.
104
105 STANDARD FILE CONTEXT
106
107 SELinux defines the file context types for the ldconfig, if you wanted
108 to store files with these types in a diffent paths, you need to execute
109 the semanage command to sepecify alternate labeling and then use
110 restorecon to put the labels on disk.
111
112 semanage fcontext -a -t ldconfig_tmp_t '/srv/myldconfig_content(/.*)?'
113 restorecon -R -v /srv/myldconfig_content
114
115 Note: SELinux often uses regular expressions to specify labels that
116 match multiple files.
117
118 The following file types are defined for ldconfig:
119
120
121
122 ldconfig_cache_t
123
124 - Set files with the ldconfig_cache_t type, if you want to store the
125 files under the /var/cache directory.
126
127
128
129 ldconfig_exec_t
130
131 - Set files with the ldconfig_exec_t type, if you want to transition an
132 executable to the ldconfig_t domain.
133
134
135 Paths:
136 /sbin/sln, /usr/sbin/sln, /sbin/ldconfig, /usr/sbin/ldconfig
137
138
139 ldconfig_tmp_t
140
141 - Set files with the ldconfig_tmp_t type, if you want to store ldconfig
142 temporary files in the /tmp directories.
143
144
145
146 Note: File context can be temporarily modified with the chcon command.
147 If you want to permanently change the file context you need to use the
148 semanage fcontext command. This will modify the SELinux labeling data‐
149 base. You will need to use restorecon to apply the labels.
150
151
153 semanage fcontext can also be used to manipulate default file context
154 mappings.
155
156 semanage permissive can also be used to manipulate whether or not a
157 process type is permissive.
158
159 semanage module can also be used to enable/disable/install/remove pol‐
160 icy modules.
161
162 semanage boolean can also be used to manipulate the booleans
163
164
165 system-config-selinux is a GUI tool available to customize SELinux pol‐
166 icy settings.
