NAME

6       ldconfig_selinux - Security Enhanced Linux Policy for the ldconfig pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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.

51

BOOLEANS

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. Disabled 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

MANAGED FILES

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       kdumpctl_tmp_t
87
88
89       ldconfig_cache_t
90
91            /var/cache/ldconfig(/.*)?
92
93       ldconfig_tmp_t
94
95
96       user_home_t
97
98            /home/[^/]+/.+

FILE CONTEXTS

102       SELinux requires files to have an extended attribute to define the file
103       type.
104
105       You can see the context of a file using the -Z option to ls
106
107       Policy governs the access  confined  processes  have  to  these  files.
108       SELinux  ldconfig policy is very flexible allowing users to setup their
109       ldconfig processes in as secure a method as possible.
110
111       STANDARD FILE CONTEXT
112
113       SELinux defines the file context types for the ldconfig, if you  wanted
114       to store files with these types in a diffent paths, you need to execute
115       the semanage command to specify alternate labeling  and  then  use  re‐
116       storecon to put the labels on disk.
117
118       semanage fcontext -a -t ldconfig_tmp_t '/srv/myldconfig_content(/.*)?'
119       restorecon -R -v /srv/myldconfig_content
120
121       Note:  SELinux  often  uses  regular expressions to specify labels that
122       match multiple files.
123
124       The following file types are defined for ldconfig:
125
126
127
128       ldconfig_cache_t
129
130       - Set files with the ldconfig_cache_t type, if you want  to  store  the
131       files under the /var/cache directory.
132
133
134
135       ldconfig_exec_t
136
137       - Set files with the ldconfig_exec_t type, if you want to transition an
138       executable to the ldconfig_t domain.
139
140
141       Paths:
142            /sbin/sln, /usr/sbin/sln, /sbin/ldconfig, /usr/sbin/ldconfig
143
144
145       ldconfig_tmp_t
146
147       - Set files with the ldconfig_tmp_t type, if you want to store ldconfig
148       temporary files in the /tmp directories.
149
150
151
152       Note:  File context can be temporarily modified with the chcon command.
153       If you want to permanently change the file context you need to use  the
154       semanage fcontext command.  This will modify the SELinux labeling data‐
155       base.  You will need to use restorecon to apply the labels.
156
157

COMMANDS

159       semanage fcontext can also be used to manipulate default  file  context
160       mappings.
161
162       semanage  permissive  can  also  be used to manipulate whether or not a
163       process type is permissive.
164
165       semanage module can also be used to enable/disable/install/remove  pol‐
166       icy modules.
167
168       semanage boolean can also be used to manipulate the booleans
169
170
171       system-config-selinux is a GUI tool available to customize SELinux pol‐
172       icy settings.
