NAME

6       httpd_unconfined_script_selinux  -  Security  Enhanced Linux Policy for
7       the httpd_unconfined_script processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the  httpd_unconfined_script  processes
11       via flexible mandatory access control.
12
13       The  httpd_unconfined_script  processes  execute  with the httpd_uncon‐
14       fined_script_t SELinux type. You can check if you have these  processes
15       running by executing the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep httpd_unconfined_script_t

ENTRYPOINTS

24       The  httpd_unconfined_script_t  SELinux  type  can  be  entered via the
25       httpd_unconfined_script_exec_t file type.
26
27       The default entrypoint paths for the  httpd_unconfined_script_t  domain
28       are the following:

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       httpd_unconfined_script policy is very flexible allowing users to setup
40       their httpd_unconfined_script processes in as secure a method as possi‐
41       ble.
42
43       The following process types are defined for httpd_unconfined_script:
44
45       httpd_unconfined_script_t
46
47       Note:  semanage  permissive -a httpd_unconfined_script_t can be used to
48       make the process  type  httpd_unconfined_script_t  permissive.  SELinux
49       does  not deny access to permissive process types, but the AVC (SELinux
50       denials) messages are still generated.

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       httpd_unconfined_script  policy  is  extremely flexible and has several
56       booleans that allow you to manipulate the policy and  run  httpd_uncon‐
57       fined_script with the tightest access possible.

60
61       If you want to deny user domains applications to map a memory region as
62       both executable and writable, this  is  dangerous  and  the  executable
63       should be reported in bugzilla, you must turn on the deny_execmem bool‐
64       ean. Enabled by default.
65
66       setsebool -P deny_execmem 1
67
68
69
70       If you want to control the ability to mmap a low area  of  the  address
71       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
72       the mmap_low_allowed boolean. Disabled by default.
73
74       setsebool -P mmap_low_allowed 1
75
76
77
78       If you want to disable kernel module loading, you must turn on the  se‐
79       cure_mode_insmod boolean. Enabled by default.
80
81       setsebool -P secure_mode_insmod 1
82
83
84
85       If  you  want to allow unconfined executables to make their heap memory
86       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
87       badly  coded  executable, but could indicate an attack. This executable
88       should be reported in bugzilla, you must turn  on  the  selinuxuser_ex‐
89       echeap boolean. Disabled by default.
90
91       setsebool -P selinuxuser_execheap 1
92
93
94
95       If  you  want  to allow unconfined executables to make their stack exe‐
96       cutable.  This should never, ever be necessary.  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_exec‐
99       stack boolean. Enabled by default.
100
101       setsebool -P selinuxuser_execstack 1

MANAGED FILES

106       The SELinux process type httpd_unconfined_script_t can manage files la‐
107       beled with the following file types.  The paths listed are the  default
108       paths  for these file types.  Note the processes UID still need to have
109       DAC permissions.
110
111       file_type
112
113            all files on the system
114
115

COMMANDS

117       semanage fcontext can also be used to manipulate default  file  context
118       mappings.
119
120       semanage  permissive  can  also  be used to manipulate whether or not a
121       process type is permissive.
122
123       semanage module can also be used to enable/disable/install/remove  pol‐
124       icy modules.
125
126       semanage boolean can also be used to manipulate the booleans
127
128
129       system-config-selinux is a GUI tool available to customize SELinux pol‐
130       icy settings.
