6 gpg_agent_selinux - Security Enhanced Linux Policy for the gpg_agent
7 processes
8
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
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
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.
50
51
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 allow usage of the gpg-agent --write-env-file option.
61 This also allows gpg-agent to manage user files, you must turn on the
62 gpg_agent_env_file boolean. Disabled by default.
63
64 setsebool -P gpg_agent_env_file 1
65
66
67
68 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70
71 setsebool -P allow_domain_fd_use 1
72
73
74
75 If you want to allow sysadm to debug or ptrace all processes, you must
76 turn on the allow_ptrace boolean. Disabled by default.
77
78 setsebool -P allow_ptrace 1
79
80
81
82 If you want to allow all domains to have the kernel load modules, you
83 must turn on the domain_kernel_load_modules boolean. Disabled by
84 default.
85
86 setsebool -P domain_kernel_load_modules 1
87
88
89
90 If you want to allow all domains to execute in fips_mode, you must turn
91 on the fips_mode boolean. Enabled by default.
92
93 setsebool -P fips_mode 1
94
95
96
97 If you want to enable reading of urandom for all domains, you must turn
98 on the global_ssp boolean. Disabled by default.
99
100 setsebool -P global_ssp 1
101
102
103
104 If you want to support NFS home directories, you must turn on the
105 use_nfs_home_dirs boolean. Disabled by default.
106
107 setsebool -P use_nfs_home_dirs 1
108
109
110
111 If you want to support SAMBA home directories, you must turn on the
112 use_samba_home_dirs boolean. Disabled by default.
113
114 setsebool -P use_samba_home_dirs 1
115
116
117
119 The SELinux process type gpg_agent_t can manage files labeled with the
120 following file types. The paths listed are the default paths for these
121 file types. Note the processes UID still need to have DAC permissions.

171 SELinux requires files to have an extended attribute to define the file
172 type.
173
174 You can see the context of a file using the -Z option to ls
175
176 Policy governs the access confined processes have to these files.
177 SELinux gpg_agent policy is very flexible allowing users to setup their
178 gpg_agent processes in as secure a method as possible.
179
180 STANDARD FILE CONTEXT
181
182 SELinux defines the file context types for the gpg_agent, if you wanted
183 to store files with these types in a diffent paths, you need to execute
184 the semanage command to sepecify alternate labeling and then use
185 restorecon to put the labels on disk.
186
187 semanage fcontext -a -t gpg_agent_tmp_t '/srv/mygpg_agent_con‐
188 tent(/.*)?'
189 restorecon -R -v /srv/mygpg_agent_content
190
191 Note: SELinux often uses regular expressions to specify labels that
192 match multiple files.
193
194 The following file types are defined for gpg_agent:
195
196
197
198 gpg_agent_exec_t
199
200 - Set files with the gpg_agent_exec_t type, if you want to transition
201 an executable to the gpg_agent_t domain.
202
203
204
205 gpg_agent_tmp_t
206
207 - Set files with the gpg_agent_tmp_t type, if you want to store gpg
208 agent temporary files in the /tmp directories.
209
210
211
212 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
217
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221
222 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224
225 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227
228 semanage boolean can also be used to manipulate the booleans
229
230
231 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
