NAME

6       gpg_helper_selinux  - Security Enhanced Linux Policy for the gpg_helper
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the gpg_helper processes  via  flexible
11       mandatory access control.
12
13       The  gpg_helper  processes  execute with the gpg_helper_t SELinux type.
14       You can check if you have these processes running by executing  the  ps
15       command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep gpg_helper_t
20
21
22

ENTRYPOINTS

24       The  gpg_helper_t SELinux type can be entered via the gpg_helper_exec_t
25       file type.
26
27       The default entrypoint paths for the gpg_helper_t domain are  the  fol‐
28       lowing:
29
30       /usr/lib/gnupg/gpgkeys.*
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       gpg_helper  policy  is  very  flexible  allowing  users  to setup their
40       gpg_helper processes in as secure a method as possible.
41
42       The following process types are defined for gpg_helper:
43
44       gpg_helper_t
45
46       Note: semanage permissive -a gpg_helper_t  can  be  used  to  make  the
47       process  type  gpg_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       gpg_helper policy is extremely flexible and has several  booleans  that
55       allow you to manipulate the policy and run gpg_helper with the tightest
56       access possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to deny any process from ptracing or  debugging  any  other
69       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
70       default.
71
72       setsebool -P deny_ptrace 1
73
74
75
76       If you want to allow any process  to  mmap  any  file  on  system  with
77       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
78       ean. Enabled by default.
79
80       setsebool -P domain_can_mmap_files 1
81
82
83
84       If you want to allow all domains write to kmsg_device, while kernel  is
85       executed  with  systemd.log_target=kmsg parameter, you must turn on the
86       domain_can_write_kmsg boolean. Disabled by default.
87
88       setsebool -P domain_can_write_kmsg 1
89
90
91
92       If you want to allow all domains to use other domains file descriptors,
93       you must turn on the domain_fd_use boolean. Enabled by default.
94
95       setsebool -P domain_fd_use 1
96
97
98
99       If  you  want to allow all domains to have the kernel load modules, you
100       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
101       default.
102
103       setsebool -P domain_kernel_load_modules 1
104
105
106
107       If you want to allow all domains to execute in fips_mode, you must turn
108       on the fips_mode boolean. Enabled by default.
109
110       setsebool -P fips_mode 1
111
112
113
114       If you want to enable reading of urandom for all domains, you must turn
115       on the global_ssp boolean. Disabled by default.
116
117       setsebool -P global_ssp 1
118
119
120
121       If  you  want  to allow confined applications to run with kerberos, you
122       must turn on the kerberos_enabled boolean. Enabled by default.
123
124       setsebool -P kerberos_enabled 1
125
126
127
128       If you want to allow system to run with  NIS,  you  must  turn  on  the
129       nis_enabled boolean. Disabled by default.
130
131       setsebool -P nis_enabled 1
132
133
134
135       If  you  want to allow confined applications to use nscd shared memory,
136       you must turn on the nscd_use_shm boolean. Disabled by default.
137
138       setsebool -P nscd_use_shm 1
139
140
141

FILE CONTEXTS

143       SELinux requires files to have an extended attribute to define the file
144       type.
145
146       You can see the context of a file using the -Z option to ls
147
148       Policy  governs  the  access  confined  processes  have to these files.
149       SELinux gpg_helper policy is very  flexible  allowing  users  to  setup
150       their gpg_helper processes in as secure a method as possible.
151
152       The following file types are defined for gpg_helper:
153
154
155
156       gpg_helper_exec_t
157
158       -  Set files with the gpg_helper_exec_t type, if you want to transition
159       an executable to the gpg_helper_t domain.
160
161
162
163       Note: File context can be temporarily modified with the chcon  command.
164       If  you want to permanently change the file context you need to use the
165       semanage fcontext command.  This will modify the SELinux labeling data‐
166       base.  You will need to use restorecon to apply the labels.
167
168

COMMANDS

170       semanage  fcontext  can also be used to manipulate default file context
171       mappings.
172
173       semanage permissive can also be used to manipulate  whether  or  not  a
174       process type is permissive.
175
176       semanage  module can also be used to enable/disable/install/remove pol‐
177       icy modules.
178
179       semanage boolean can also be used to manipulate the booleans
180
181
182       system-config-selinux is a GUI tool available to customize SELinux pol‐
183       icy settings.
