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.

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