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 users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type gpg_agent_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.
100 cifs_t
102 ecryptfs_t
105 /home/[^/]+/.Private(/.*)?
107 /home/[^/]+/.ecryptfs(/.*)?
108 fusefs_t
110 /var/run/user/[^/]*/gvfs
112 gnome_home_type
114 gpg_agent_tmp_t
117 /home/[^/]+/.gnupg/log-socket
119 gpg_agent_tmpfs_t
121 gpg_secret_t
124 /root/.gnupg(/.+)?
126 /etc/mail/spamassassin/sa-update-keys(/.*)?
127 /home/[^/]+/.gnupg(/.+)?
128 nfs_t
130 user_home_t
133 /home/[^/]+/.+
135 user_tmp_type
137 all user tmp files
139
142 SELinux requires files to have an extended attribute to define the file
143 type.
144 You can see the context of a file using the -Z option to ls
146 Policy governs the access confined processes have to these files.
148 SELinux gpg_agent policy is very flexible allowing users to setup their
149 gpg_agent processes in as secure a method as possible.
150 STANDARD FILE CONTEXT
152 SELinux defines the file context types for the gpg_agent, if you wanted
154 to store files with these types in a diffent paths, you need to execute
155 the semanage command to sepecify alternate labeling and then use
156 restorecon to put the labels on disk.
157 semanage fcontext -a -t gpg_agent_tmpfs_t '/srv/mygpg_agent_con‐
159 tent(/.*)?'
160 restorecon -R -v /srv/mygpg_agent_content
161 Note: SELinux often uses regular expressions to specify labels that
163 match multiple files.
164 The following file types are defined for gpg_agent:
166 gpg_agent_exec_t
170 - Set files with the gpg_agent_exec_t type, if you want to transition
172 an executable to the gpg_agent_t domain.
173 gpg_agent_tmp_t
177 - Set files with the gpg_agent_tmp_t type, if you want to store gpg
179 agent temporary files in the /tmp directories.
180 gpg_agent_tmpfs_t
184 - Set files with the gpg_agent_tmpfs_t type, if you want to store gpg
186 agent files on a tmpfs file system.
187 Note: File context can be temporarily modified with the chcon command.
191 If you want to permanently change the file context you need to use the
192 semanage fcontext command. This will modify the SELinux labeling data‐
193 base. You will need to use restorecon to apply the labels.
194
197 semanage fcontext can also be used to manipulate default file context
198 mappings.
199 semanage permissive can also be used to manipulate whether or not a
201 process type is permissive.
202 semanage module can also be used to enable/disable/install/remove pol‐
204 icy modules.
205 semanage boolean can also be used to manipulate the booleans
207 system-config-selinux is a GUI tool available to customize SELinux pol‐
210 icy settings.
