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 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 For example:
18 ps -eZ | grep gpg_agent_t
20
24 The gpg_agent_t SELinux type can be entered via the gpg_agent_exec_t
25 file type.
26 The default entrypoint paths for the gpg_agent_t domain are the follow‐
28 ing:
29 /usr/bin/gpg-agent
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for gpg_agent:
43 gpg_agent_t
45 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
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 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 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type gpg_agent_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

134 SELinux requires files to have an extended attribute to define the file
135 type.
136 You can see the context of a file using the -Z option to ls
138 Policy governs the access confined processes have to these files.
140 SELinux gpg_agent policy is very flexible allowing users to setup their
141 gpg_agent processes in as secure a method as possible.
142 STANDARD FILE CONTEXT
144 SELinux defines the file context types for the gpg_agent, if you wanted
146 to store files with these types in a diffent paths, you need to execute
147 the semanage command to specify alternate labeling and then use re‐
148 storecon to put the labels on disk.
149 semanage fcontext -a -t gpg_agent_tmpfs_t '/srv/mygpg_agent_con‐
151 tent(/.*)?'
152 restorecon -R -v /srv/mygpg_agent_content
153 Note: SELinux often uses regular expressions to specify labels that
155 match multiple files.
156 The following file types are defined for gpg_agent:
158 gpg_agent_exec_t
162 - Set files with the gpg_agent_exec_t type, if you want to transition
164 an executable to the gpg_agent_t domain.
165 gpg_agent_tmp_t
169 - Set files with the gpg_agent_tmp_t type, if you want to store gpg
171 agent temporary files in the /tmp directories.
172 gpg_agent_tmpfs_t
176 - Set files with the gpg_agent_tmpfs_t type, if you want to store gpg
178 agent files on a tmpfs file system.
179 Note: File context can be temporarily modified with the chcon command.
183 If you want to permanently change the file context you need to use the
184 semanage fcontext command. This will modify the SELinux labeling data‐
185 base. You will need to use restorecon to apply the labels.
186
189 semanage fcontext can also be used to manipulate default file context
190 mappings.
191 semanage permissive can also be used to manipulate whether or not a
193 process type is permissive.
194 semanage module can also be used to enable/disable/install/remove pol‐
196 icy modules.
197 semanage boolean can also be used to manipulate the booleans
199 system-config-selinux is a GUI tool available to customize SELinux pol‐
202 icy settings.
