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 all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type gpg_agent_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

113 SELinux requires files to have an extended attribute to define the file
114 type.
115
116 You can see the context of a file using the -Z option to ls
117
118 Policy governs the access confined processes have to these files.
119 SELinux gpg_agent policy is very flexible allowing users to setup their
120 gpg_agent processes in as secure a method as possible.
121
122 STANDARD FILE CONTEXT
123
124 SELinux defines the file context types for the gpg_agent, if you wanted
125 to store files with these types in a diffent paths, you need to execute
126 the semanage command to sepecify alternate labeling and then use
127 restorecon to put the labels on disk.
128
129 semanage fcontext -a -t gpg_agent_tmpfs_t '/srv/mygpg_agent_con‐
130 tent(/.*)?'
131 restorecon -R -v /srv/mygpg_agent_content
132
133 Note: SELinux often uses regular expressions to specify labels that
134 match multiple files.
135
136 The following file types are defined for gpg_agent:
137
138
139
140 gpg_agent_exec_t
141
142 - Set files with the gpg_agent_exec_t type, if you want to transition
143 an executable to the gpg_agent_t domain.
144
145
146
147 gpg_agent_tmp_t
148
149 - Set files with the gpg_agent_tmp_t type, if you want to store gpg
150 agent temporary files in the /tmp directories.
151
152
153
154 gpg_agent_tmpfs_t
155
156 - Set files with the gpg_agent_tmpfs_t type, if you want to store gpg
157 agent files on a tmpfs file system.
158
159
160
161 Note: File context can be temporarily modified with the chcon command.
162 If you want to permanently change the file context you need to use the
163 semanage fcontext command. This will modify the SELinux labeling data‐
164 base. You will need to use restorecon to apply the labels.
165
166
168 semanage fcontext can also be used to manipulate default file context
169 mappings.
170
171 semanage permissive can also be used to manipulate whether or not a
172 process type is permissive.
173
174 semanage module can also be used to enable/disable/install/remove pol‐
175 icy modules.
176
177 semanage boolean can also be used to manipulate the booleans
178
179
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
181 icy settings.
