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(64)?/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 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 confined applications to run with kerberos, you
68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73
74       If you want to allow sysadm to debug or ptrace all processes, you  must
75       turn on the allow_ptrace boolean. Disabled by default.
76
77       setsebool -P allow_ptrace 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       allow_ypbind boolean. Disabled by default.
83
84       setsebool -P allow_ypbind 1
85
86
87
88       If you want to allow all domains to have the kernel load  modules,  you
89       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
90       default.
91
92       setsebool -P domain_kernel_load_modules 1
93
94
95
96       If you want to allow all domains to execute in fips_mode, you must turn
97       on the fips_mode boolean. Enabled by default.
98
99       setsebool -P fips_mode 1
100
101
102
103       If you want to enable reading of urandom for all domains, you must turn
104       on the global_ssp boolean. Disabled by default.
105
106       setsebool -P global_ssp 1
107
108
109
110       If you want to allow confined applications to use nscd  shared  memory,
111       you must turn on the nscd_use_shm boolean. Enabled by default.
112
113       setsebool -P nscd_use_shm 1
114

MANAGED FILES

118       The SELinux process type gpg_helper_t can manage files labeled with the
119       following file types.  The paths listed are the default paths for these
120       file types.  Note the processes UID still need to have DAC permissions.
121
122       initrc_tmp_t
123
124
125       mnt_t
126
127            /mnt(/[^/]*)
128            /mnt(/[^/]*)?
129            /rhev(/[^/]*)?
130            /media(/[^/]*)
131            /media(/[^/]*)?
132            /etc/rhgb(/.*)?
133            /media/.hal-.*
134            /net
135            /afs
136            /rhev
137            /misc
138
139       tmp_t
140
141            /tmp
142            /usr/tmp
143            /var/tmp
144            /tmp-inst
145            /var/tmp-inst
146            /var/tmp/vi.recover

FILE CONTEXTS

150       SELinux requires files to have an extended attribute to define the file
151       type.
152
153       You can see the context of a file using the -Z option to ls
154
155       Policy governs the access  confined  processes  have  to  these  files.
156       SELinux  gpg_helper  policy  is  very  flexible allowing users to setup
157       their gpg_helper processes in as secure a method as possible.
158
159       The following file types are defined for gpg_helper:
160
161
162
163       gpg_helper_exec_t
164
165       - Set files with the gpg_helper_exec_t type, if you want to  transition
166       an executable to the gpg_helper_t domain.
167
168
169
170       Note:  File context can be temporarily modified with the chcon command.
171       If you want to permanently change the file context you need to use  the
172       semanage fcontext command.  This will modify the SELinux labeling data‐
173       base.  You will need to use restorecon to apply the labels.
174
175

COMMANDS

177       semanage fcontext can also be used to manipulate default  file  context
178       mappings.
179
180       semanage  permissive  can  also  be used to manipulate whether or not a
181       process type is permissive.
182
183       semanage module can also be used to enable/disable/install/remove  pol‐
184       icy modules.
185
186       semanage boolean can also be used to manipulate the booleans
187
188
189       system-config-selinux is a GUI tool available to customize SELinux pol‐
190       icy settings.
