NAME

6       httpd_helper_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       httpd_helper processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The    httpd_helper_t   SELinux   type   can   be   entered   via   the
25       httpd_helper_exec_t file type.
26
27       The default entrypoint paths for the httpd_helper_t domain are the fol‐
28       lowing:
29
30       /usr/bin/htsslpass
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       httpd_helper  policy  is  very  flexible  allowing users to setup their
40       httpd_helper processes in as secure a method as possible.
41
42       The following process types are defined for httpd_helper:
43
44       httpd_helper_t
45
46       Note: semanage permissive -a httpd_helper_t can be  used  to  make  the
47       process type httpd_helper_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       httpd_helper policy is extremely flexible and has several booleans that
55       allow you to manipulate the policy and run httpd_helper with the tight‐
56       est access possible.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you want to allow sysadm to debug or ptrace all processes, you must
68       turn on the allow_ptrace boolean. Disabled by default.
69
70       setsebool -P allow_ptrace 1
71
72
73
74       If you want to allow all domains to have the kernel load  modules,  you
75       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
76       default.
77
78       setsebool -P domain_kernel_load_modules 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If you want to enable reading of urandom for all domains, you must turn
90       on the global_ssp boolean. Disabled by default.
91
92       setsebool -P global_ssp 1
93
94
95
96       If you want to unify HTTPD to communicate with the terminal. Needed for
97       entering the passphrase for certificates at the terminal, you must turn
98       on the httpd_tty_comm boolean. Disabled by default.
99
100       setsebool -P httpd_tty_comm 1

MANAGED FILES

105       The SELinux process type httpd_helper_t can manage files  labeled  with
106       the  following  file types.  The paths listed are the default paths for
107       these file types.  Note the processes UID still need to have  DAC  per‐
108       missions.
109
110       initrc_tmp_t
111
112
113       mnt_t
114
115            /mnt(/[^/]*)
116            /mnt(/[^/]*)?
117            /rhev(/[^/]*)?
118            /media(/[^/]*)
119            /media(/[^/]*)?
120            /etc/rhgb(/.*)?
121            /media/.hal-.*
122            /net
123            /afs
124            /rhev
125            /misc
126
127       tmp_t
128
129            /tmp
130            /usr/tmp
131            /var/tmp
132            /tmp-inst
133            /var/tmp-inst
134            /var/tmp/vi.recover

FILE CONTEXTS

138       SELinux requires files to have an extended attribute to define the file
139       type.
140
141       You can see the context of a file using the -Z option to ls
142
143       Policy governs the access  confined  processes  have  to  these  files.
144       SELinux  httpd_helper  policy  is very flexible allowing users to setup
145       their httpd_helper processes in as secure a method as possible.
146
147       The following file types are defined for httpd_helper:
148
149
150
151       httpd_helper_exec_t
152
153       - Set files with the httpd_helper_exec_t type, if you want  to  transi‐
154       tion an executable to the httpd_helper_t domain.
155
156
157
158       Note:  File context can be temporarily modified with the chcon command.
159       If you want to permanently change the file context you need to use  the
160       semanage fcontext command.  This will modify the SELinux labeling data‐
161       base.  You will need to use restorecon to apply the labels.
162
163

COMMANDS

165       semanage fcontext can also be used to manipulate default  file  context
166       mappings.
167
168       semanage  permissive  can  also  be used to manipulate whether or not a
169       process type is permissive.
170
171       semanage module can also be used to enable/disable/install/remove  pol‐
172       icy modules.
173
174       semanage boolean can also be used to manipulate the booleans
175
176
177       system-config-selinux is a GUI tool available to customize SELinux pol‐
178       icy settings.
