NAME

6       gpg_agent_selinux  -  Security  Enhanced Linux Policy for the gpg_agent
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  gpg_agent_t  SELinux  type can be entered via the gpg_agent_exec_t
25       file type.
26
27       The default entrypoint paths for the gpg_agent_t domain are the follow‐
28       ing:
29
30       /usr/bin/gpg-agent
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_agent  policy  is  very  flexible  allowing  users  to  setup their
40       gpg_agent processes in as secure a method as possible.
41
42       The following process types are defined for gpg_agent:
43
44       gpg_agent_t
45
46       Note: semanage permissive -a  gpg_agent_t  can  be  used  to  make  the
47       process  type  gpg_agent_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_agent policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run gpg_agent with the tightest
56       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 support ecryptfs home directories, you must turn on the
114       use_ecryptfs_home_dirs boolean. Disabled by default.
115
116       setsebool -P use_ecryptfs_home_dirs 1
117
118
119
120       If you want to support fusefs home directories, you must  turn  on  the
121       use_fusefs_home_dirs boolean. Disabled by default.
122
123       setsebool -P use_fusefs_home_dirs 1
124
125
126
127       If  you  want  to  support  NFS  home directories, you must turn on the
128       use_nfs_home_dirs boolean. Disabled by default.
129
130       setsebool -P use_nfs_home_dirs 1

MANAGED FILES

142       The  SELinux process type gpg_agent_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.
145
146       cifs_t
147
148
149       ecryptfs_t
150
151            /home/[^/]+/.Private(/.*)?
152            /home/[^/]+/.ecryptfs(/.*)?
153
154       fusefs_t

FILE CONTEXTS

184       SELinux requires files to have an extended attribute to define the file
185       type.
186
187       You can see the context of a file using the -Z option to ls
188
189       Policy governs the access  confined  processes  have  to  these  files.
190       SELinux gpg_agent policy is very flexible allowing users to setup their
191       gpg_agent processes in as secure a method as possible.
192
193       STANDARD FILE CONTEXT
194
195       SELinux defines the file context types for the gpg_agent, if you wanted
196       to store files with these types in a diffent paths, you need to execute
197       the semanage command  to  sepecify  alternate  labeling  and  then  use
198       restorecon to put the labels on disk.
199
200       semanage   fcontext   -a   -t   gpg_agent_tmp_t  '/srv/mygpg_agent_con‐
201       tent(/.*)?'
202       restorecon -R -v /srv/mygpg_agent_content
203
204       Note: SELinux often uses regular expressions  to  specify  labels  that
205       match multiple files.
206
207       The following file types are defined for gpg_agent:
208
209
210
211       gpg_agent_exec_t
212
213       -  Set  files with the gpg_agent_exec_t type, if you want to transition
214       an executable to the gpg_agent_t domain.
215
216
217
218       gpg_agent_tmp_t
219
220       - Set files with the gpg_agent_tmp_t type, if you  want  to  store  gpg
221       agent temporary files in the /tmp directories.
222
223
224
225       Note:  File context can be temporarily modified with the chcon command.
226       If you want to permanently change the file context you need to use  the
227       semanage fcontext command.  This will modify the SELinux labeling data‐
228       base.  You will need to use restorecon to apply the labels.
229
230

COMMANDS

232       semanage fcontext can also be used to manipulate default  file  context
233       mappings.
234
235       semanage  permissive  can  also  be used to manipulate whether or not a
236       process type is permissive.
237
238       semanage module can also be used to enable/disable/install/remove  pol‐
239       icy modules.
240
241       semanage boolean can also be used to manipulate the booleans
242
243
244       system-config-selinux is a GUI tool available to customize SELinux pol‐
245       icy settings.
