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

22

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 deny any process from ptracing or  debugging  any  other
61       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
62       default.
63
64       setsebool -P deny_ptrace 1
65
66
67
68       If you want to allow any process  to  mmap  any  file  on  system  with
69       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
70       ean. Enabled by default.
71
72       setsebool -P domain_can_mmap_files 1
73
74
75
76       If you want to allow all domains write to kmsg_device, while kernel  is
77       executed  with  systemd.log_target=kmsg parameter, you must turn on the
78       domain_can_write_kmsg boolean. Disabled by default.
79
80       setsebool -P domain_can_write_kmsg 1
81
82
83
84       If you want to allow all domains to use other domains file descriptors,
85       you must turn on the domain_fd_use boolean. Enabled by default.
86
87       setsebool -P domain_fd_use 1
88
89
90
91       If  you  want to allow all domains to have the kernel load modules, you
92       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
93       default.
94
95       setsebool -P domain_kernel_load_modules 1
96
97
98
99       If you want to allow all domains to execute in fips_mode, you must turn
100       on the fips_mode boolean. Enabled by default.
101
102       setsebool -P fips_mode 1
103
104
105
106       If you want to enable reading of urandom for all domains, you must turn
107       on the global_ssp boolean. Disabled by default.
108
109       setsebool -P global_ssp 1
110
111
112
113       If you want to unify HTTPD to communicate with the terminal. Needed for
114       entering the passphrase for certificates at the terminal, you must turn
115       on the httpd_tty_comm boolean. Disabled by default.
116
117       setsebool -P httpd_tty_comm 1
118

FILE CONTEXTS

122       SELinux requires files to have an extended attribute to define the file
123       type.
124
125       You can see the context of a file using the -Z option to ls
126
127       Policy governs the access  confined  processes  have  to  these  files.
128       SELinux  httpd_helper  policy  is very flexible allowing users to setup
129       their httpd_helper processes in as secure a method as possible.
130
131       The following file types are defined for httpd_helper:
132
133
134
135       httpd_helper_exec_t
136
137       - Set files with the httpd_helper_exec_t type, if you want  to  transi‐
138       tion an executable to the httpd_helper_t domain.
139
140
141
142       Note:  File context can be temporarily modified with the chcon command.
143       If you want to permanently change the file context you need to use  the
144       semanage fcontext command.  This will modify the SELinux labeling data‐
145       base.  You will need to use restorecon to apply the labels.
146
147

COMMANDS

149       semanage fcontext can also be used to manipulate default  file  context
150       mappings.
151
152       semanage  permissive  can  also  be used to manipulate whether or not a
153       process type is permissive.
154
155       semanage module can also be used to enable/disable/install/remove  pol‐
156       icy modules.
157
158       semanage boolean can also be used to manipulate the booleans
159
160
161       system-config-selinux is a GUI tool available to customize SELinux pol‐
162       icy settings.
