7 for the dirsrvadmin_unconfined_script processes
8
10 Security-Enhanced Linux secures the dirsrvadmin_unconfined_script pro‐
11 cesses via flexible mandatory access control.
12
13 The dirsrvadmin_unconfined_script processes execute with the dirsrvad‐
14 min_unconfined_script_t SELinux type. You can check if you have these
15 processes running by executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dirsrvadmin_unconfined_script_t
20
21
22
24 The dirsrvadmin_unconfined_script_t SELinux type can be entered via the
25 dirsrvadmin_unconfined_script_exec_t, shell_exec_t file types.
26
27 The default entrypoint paths for the dirsrvadmin_unconfined_script_t
28 domain are the following:
29
30 /usr/lib/dirsrv/cgi-bin/ds_create, /usr/lib/dirsrv/cgi-bin/ds_remove,
31 /bin/d?ash, /bin/ksh.*, /bin/zsh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
32 /usr/bin/zsh.*, /bin/esh, /bin/bash, /bin/fish, /bin/mksh, /bin/sash,
33 /bin/tcsh, /bin/yash, /bin/bash2, /usr/bin/esh, /sbin/nologin,
34 /usr/bin/bash, /usr/bin/fish, /usr/bin/mksh, /usr/bin/sash,
35 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/bash2, /usr/sbin/sesh,
36 /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh, /usr/sbin/nolo‐
37 gin, /usr/bin/git-shell, /usr/sbin/scponlyc, /usr/libexec/sudo/sesh,
38 /usr/bin/cockpit-bridge, /usr/libexec/cockpit-agent, /usr/libexec/git-

42 SELinux defines process types (domains) for each process running on the
43 system
44
45 You can see the context of a process using the -Z option to ps
46
47 Policy governs the access confined processes have to files. SELinux
48 dirsrvadmin_unconfined_script policy is very flexible allowing users to
49 setup their dirsrvadmin_unconfined_script processes in as secure a
50 method as possible.
51
52 The following process types are defined for dirsrvadmin_uncon‐
53 fined_script:
54
55 dirsrvadmin_unconfined_script_t
56
57 Note: semanage permissive -a dirsrvadmin_unconfined_script_t can be
58 used to make the process type dirsrvadmin_unconfined_script_t permis‐
59 sive. SELinux does not deny access to permissive process types, but the
60 AVC (SELinux denials) messages are still generated.
61
62
64 SELinux policy is customizable based on least access required. dirsr‐
65 vadmin_unconfined_script policy is extremely flexible and has several
66 booleans that allow you to manipulate the policy and run dirsrvad‐
67 min_unconfined_script with the tightest access possible.
68
69
70
71 If you want to deny user domains applications to map a memory region as
72 both executable and writable, this is dangerous and the executable
73 should be reported in bugzilla, you must turn on the deny_execmem bool‐
74 ean. Disabled by default.
75
76 setsebool -P deny_execmem 1
77
78
79
80 If you want to control the ability to mmap a low area of the address
81 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
82 the mmap_low_allowed boolean. Disabled by default.
83
84 setsebool -P mmap_low_allowed 1
85
86
87
88 If you want to disable kernel module loading, you must turn on the se‐
89 cure_mode_insmod boolean. Disabled by default.
90
91 setsebool -P secure_mode_insmod 1
92
93
94
95 If you want to allow unconfined executables to make their heap memory
96 executable. Doing this is a really bad idea. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
99 echeap boolean. Disabled by default.
100
101 setsebool -P selinuxuser_execheap 1
102
103
104
105 If you want to allow unconfined executables to make their stack exe‐
106 cutable. This should never, ever be necessary. Probably indicates a
107 badly coded executable, but could indicate an attack. This executable
108 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
109 stack boolean. Enabled by default.
110
111 setsebool -P selinuxuser_execstack 1

113
114
116 The SELinux process type dirsrvadmin_unconfined_script_t can manage
117 files labeled with the following file types. The paths listed are the
118 default paths for these file types. Note the processes UID still need
119 to have DAC permissions.
120
121 file_type
122
123 all files on the system
124
125
127 SELinux requires files to have an extended attribute to define the file
128 type.
129
130 You can see the context of a file using the -Z option to ls
131
132 Policy governs the access confined processes have to these files.
133 SELinux dirsrvadmin_unconfined_script policy is very flexible allowing
134 users to setup their dirsrvadmin_unconfined_script processes in as se‐
135 cure a method as possible.
136
137 STANDARD FILE CONTEXT
138
139 SELinux defines the file context types for the dirsrvadmin_uncon‐
140 fined_script, if you wanted to store files with these types in a dif‐
141 ferent paths, you need to execute the semanage command to specify al‐
142 ternate labeling and then use restorecon to put the labels on disk.
143
144 semanage fcontext -a -t dirsrvadmin_unconfined_script_exec_t
145 '/srv/dirsrvadmin_unconfined_script/content(/.*)?'
146 restorecon -R -v /srv/mydirsrvadmin_unconfined_script_content
147
148 Note: SELinux often uses regular expressions to specify labels that
149 match multiple files.
150
151 The following file types are defined for dirsrvadmin_unconfined_script:
152
153
154
155 dirsrvadmin_unconfined_script_exec_t
156
157 - Set files with the dirsrvadmin_unconfined_script_exec_t type, if you
158 want to transition an executable to the dirsrvadmin_unconfined_script_t
159 domain.
160
161
162 Paths:
163 /usr/lib/dirsrv/cgi-bin/ds_create, /usr/lib/dirsrv/cgi-bin/ds_re‐
164 move
165
166
167 Note: File context can be temporarily modified with the chcon command.
168 If you want to permanently change the file context you need to use the
169 semanage fcontext command. This will modify the SELinux labeling data‐
170 base. You will need to use restorecon to apply the labels.
171
172
174 semanage fcontext can also be used to manipulate default file context
175 mappings.
176
177 semanage permissive can also be used to manipulate whether or not a
178 process type is permissive.
179
180 semanage module can also be used to enable/disable/install/remove pol‐
181 icy modules.
182
183 semanage boolean can also be used to manipulate the booleans
184
185
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
187 icy settings.
