6 dirsrvadmin_unconfined_script_selinux - Security Enhanced Linux Policy
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 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 For example:
18 ps -eZ | grep dirsrvadmin_unconfined_script_t
20
24 The dirsrvadmin_unconfined_script_t SELinux type can be entered via the
25 shell_exec_t, dirsrvadmin_unconfined_script_exec_t file types.
26 The default entrypoint paths for the dirsrvadmin_unconfined_script_t
28 domain are the following:
29 /bin/d?ash, /bin/ksh.*, /bin/zsh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
31 /usr/bin/zsh.*, /bin/esh, /bin/bash, /bin/fish, /bin/mksh, /bin/sash,
32 /bin/tcsh, /bin/yash, /bin/bash2, /usr/bin/esh, /sbin/nologin,
33 /usr/bin/bash, /usr/bin/fish, /usr/bin/mksh, /usr/bin/sash,
34 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/bash2, /usr/sbin/sesh,
35 /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh, /usr/sbin/nolo‐
36 gin, /usr/bin/git-shell, /usr/sbin/scponlyc, /usr/libexec/sudo/sesh,
37 /usr/bin/cockpit-bridge, /usr/libexec/cockpit-agent, /usr/libexec/git-
38 core/git-shell, /usr/lib/dirsrv/cgi-bin/ds_create, /usr/lib/dirsrv/cgi-

42 SELinux defines process types (domains) for each process running on the
43 system
44 You can see the context of a process using the -Z option to ps
46 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 The following process types are defined for dirsrvadmin_uncon‐
53 fined_script:
54 dirsrvadmin_unconfined_script_t
56 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
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 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. Enabled by default.
75 setsebool -P deny_execmem 1
77 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 setsebool -P mmap_low_allowed 1
85 If you want to disable kernel module loading, you must turn on the se‐
89 cure_mode_insmod boolean. Enabled by default.
90 setsebool -P secure_mode_insmod 1
92 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 setsebool -P selinuxuser_execheap 1
102 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 setsebool -P selinuxuser_execstack 1

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 file_type
122 all files on the system
124
127 SELinux requires files to have an extended attribute to define the file
128 type.
129 You can see the context of a file using the -Z option to ls
131 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 The following file types are defined for dirsrvadmin_unconfined_script:
138 dirsrvadmin_unconfined_script_exec_t
142 - Set files with the dirsrvadmin_unconfined_script_exec_t type, if you
144 want to transition an executable to the dirsrvadmin_unconfined_script_t
145 domain.
146 Paths:
149 /usr/lib/dirsrv/cgi-bin/ds_create, /usr/lib/dirsrv/cgi-bin/ds_re‐
150 move
151 Note: File context can be temporarily modified with the chcon command.
154 If you want to permanently change the file context you need to use the
155 semanage fcontext command. This will modify the SELinux labeling data‐
156 base. You will need to use restorecon to apply the labels.
157
160 semanage fcontext can also be used to manipulate default file context
161 mappings.
162 semanage permissive can also be used to manipulate whether or not a
164 process type is permissive.
165 semanage module can also be used to enable/disable/install/remove pol‐
167 icy modules.
168 semanage boolean can also be used to manipulate the booleans
170 system-config-selinux is a GUI tool available to customize SELinux pol‐
173 icy settings.
