gpg_selinux(8) gpg SELinux Policy documentation gpg_selinux(8)NAMEgpg_selinux - Security Enhanced Linux Policy for the gpg processes
DESCRIPTION
Security-Enhanced Linux secures the gpg processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. gpg
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run gpg with the tightest access possible.
If you want to allow usage of the gpg-agent --write-env-file option.
This also allows gpg-agent to manage user files, you must turn on the
gpg_agent_env_file boolean.
setsebool -P gpg_agent_env_file 1
If you want to allow httpd to run gpg in gpg-web domai, you must turn
on the httpd_use_gpg boolean.
setsebool -P httpd_use_gpg 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the gpg_t,
gpg_helper_t, gpg_pinentry_t, you must turn on the authlogin_nss‐
witch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
gpg_t, gpg_helper_t, gpg_pinentry_t, you must turn on the allow_ker‐
beros boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the gpg_t, gpg_helper_t,
gpg_pinentry_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
SHARING FILES
If you want to share files with multiple domains (Apache, FTP, rsync,
Samba), you can set a file context of public_content_t and public_con‐
tent_rw_t. These context allow any of the above domains to read the
content. If you want a particular domain to write to the public_con‐
tent_rw_t domain, you must set the appropriate boolean.
Allow gpg servers to read the /var/gpg directory by adding the pub‐
lic_content_t file type to the directory and by restoring the file
type.
semanage fcontext -a -t public_content_t "/var/gpg(/.*)?"
restorecon -F -R -v /var/gpg
Allow gpg servers to read and write /var/tmp/incoming by adding the
public_content_rw_t type to the directory and by restoring the file
type. This also requires the allow_gpgd_anon_write boolean to be set.
semanage fcontext -a -t public_content_rw_t "/var/gpg/incoming(/.*)?"
restorecon -F -R -v /var/gpg/incoming
If you want to allow gpg web domain to modify public files used for
public file transfer services., you must turn on the gpg_web_anon_write
boolean.
setsebool -P gpg_web_anon_write 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux gpg policy is very flexible allowing users to setup their gpg
processes in as secure a method as possible.
The following file types are defined for gpg:
gpg_agent_exec_t
- Set files with the gpg_agent_exec_t type, if you want to transition
an executable to the gpg_agent_t domain.
gpg_agent_tmp_t
- Set files with the gpg_agent_tmp_t type, if you want to store gpg
agent temporary files in the /tmp directories.
gpg_exec_t
- Set files with the gpg_exec_t type, if you want to transition an exe‐
cutable to the gpg_t domain.
Paths:
/usr/bin/gpg(2)?, /usr/bin/kgpg, /usr/lib/gnupg/.*
gpg_helper_exec_t
- Set files with the gpg_helper_exec_t type, if you want to transition
an executable to the gpg_helper_t domain.
gpg_pinentry_tmp_t
- Set files with the gpg_pinentry_tmp_t type, if you want to store gpg
pinentry temporary files in the /tmp directories.
gpg_pinentry_tmpfs_t
- Set files with the gpg_pinentry_tmpfs_t type, if you want to store
gpg pinentry files on a tmpfs file system.
gpg_secret_t
- Set files with the gpg_secret_t type, if you want to treat the files
as gpg se secret data.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
gpg policy is very flexible allowing users to setup their gpg processes
in as secure a method as possible.
The following process types are defined for gpg:
gpg_t, gpg_pinentry_t, gpg_helper_t, gpg_web_t, gpg_agent_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
