NAME

6       httpd_user_script_selinux  -  Security  Enhanced  Linux  Policy for the
7       httpd_user_script processes
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  httpd_user_script  processes  via
11       flexible mandatory access control.
12
13       The  httpd_user_script  processes  execute with the httpd_user_script_t
14       SELinux type. You can check if you have these processes running by exe‐
15       cuting the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep httpd_user_script_t
20

22

ENTRYPOINTS

24       The   httpd_user_script_t   SELinux   type   can  be  entered  via  the
25       shell_exec_t,          httpd_user_script_exec_t,          httpdcontent,
26       httpd_user_script_exec_t file types.
27
28       The default entrypoint paths for the httpd_user_script_t domain are the
29       following:
30
31       /bin/d?ash,  /bin/zsh.*,  /bin/ksh.*,  /usr/bin/d?ash,  /usr/bin/ksh.*,
32       /usr/bin/zsh.*,  /bin/esh,  /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
33       /bin/bash,   /bin/fish,   /bin/bash2,   /usr/bin/esh,    /usr/bin/sash,
34       /usr/bin/tcsh,     /usr/bin/yash,     /usr/bin/mksh,     /usr/bin/fish,
35       /usr/bin/bash,    /sbin/nologin,    /usr/sbin/sesh,     /usr/bin/bash2,
36       /usr/sbin/smrsh,          /usr/bin/scponly,          /usr/sbin/nologin,
37       /usr/libexec/sesh,       /usr/sbin/scponlyc,        /usr/bin/git-shell,
38       /usr/libexec/sudo/sesh,  /usr/bin/cockpit-bridge, /usr/libexec/cockpit-
39       agent, /usr/libexec/git-core/git-shell,  /home/[^/]+/((www)|(web)|(pub‐
40       lic_html))/cgi-bin(/.+)?,  /home/[^/]+/((www)|(web)|(public_html))/cgi-
41       bin(/.+)?

PROCESS TYPES

44       SELinux defines process types (domains) for each process running on the
45       system
46
47       You can see the context of a process using the -Z option to ps
48
49       Policy  governs  the  access confined processes have to files.  SELinux
50       httpd_user_script policy is very flexible allowing users to setup their
51       httpd_user_script processes in as secure a method as possible.
52
53       The following process types are defined for httpd_user_script:
54
55       httpd_user_script_t
56
57       Note:  semanage  permissive  -a httpd_user_script_t can be used to make
58       the process type httpd_user_script_t permissive. SELinux does not  deny
59       access  to permissive process types, but the AVC (SELinux denials) mes‐
60       sages are still generated.
61
62

BOOLEANS

64       SELinux  policy  is  customizable  based  on  least  access   required.
65       httpd_user_script policy is extremely flexible and has several booleans
66       that allow you to manipulate the policy and run httpd_user_script  with
67       the tightest access possible.
68
69
70
71       If you want to allow users to resolve user passwd entries directly from
72       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
73       gin_nsswitch_use_ldap boolean. Disabled by default.

MANAGED FILES

182       The  SELinux  process type httpd_user_script_t can manage files labeled
183       with the following file types.  The paths listed are the default  paths
184       for  these  file  types.  Note the processes UID still need to have DAC
185       permissions.
186
187       httpd_user_content_t
188
189            /home/[^/]+/((www)|(web)|(public_html))(/.+)?
190
191       httpd_user_ra_content_t
192
193            /home/[^/]+/((www)|(web)|(public_html))(/.*)?/logs(/.*)?
194
195       httpd_user_rw_content_t
196
197
198

FILE CONTEXTS

200       SELinux requires files to have an extended attribute to define the file
201       type.
202
203       You can see the context of a file using the -Z option to ls
204
205       Policy  governs  the  access  confined  processes  have to these files.
206       SELinux httpd_user_script policy is very  flexible  allowing  users  to
207       setup their httpd_user_script processes in as secure a method as possi‐
208       ble.
209
210       The following file types are defined for httpd_user_script:
211
212
213
214       httpd_user_script_exec_t
215
216       - Set files with the httpd_user_script_exec_t  type,  if  you  want  to
217       transition an executable to the httpd_user_script_t domain.
218
219
220
221       Note:  File context can be temporarily modified with the chcon command.
222       If you want to permanently change the file context you need to use  the
223       semanage fcontext command.  This will modify the SELinux labeling data‐
224       base.  You will need to use restorecon to apply the labels.
225
226

COMMANDS

228       semanage fcontext can also be used to manipulate default  file  context
229       mappings.
230
231       semanage  permissive  can  also  be used to manipulate whether or not a
232       process type is permissive.
233
234       semanage module can also be used to enable/disable/install/remove  pol‐
235       icy modules.
236
237       semanage boolean can also be used to manipulate the booleans
238
239
240       system-config-selinux is a GUI tool available to customize SELinux pol‐
241       icy settings.
