glance_api_selinux(8) SELinux Policy glance_api glance_api_selinux(8)NAMEglance_api_selinux - Security Enhanced Linux Policy for the glance_api
processes
DESCRIPTION
Security-Enhanced Linux secures the glance_api processes via flexible
mandatory access control.
The glance_api processes execute with the glance_api_t SELinux type.
You can check if you have these processes running by executing the ps
command with the -Z qualifier.
For example:
ps -eZ | grep glance_api_t
ENTRYPOINTS
The glance_api_t SELinux type can be entered via the glance_api_exec_t
file type.
The default entrypoint paths for the glance_api_t domain are the fol‐
lowing:
/usr/bin/glance-api
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
glance_api policy is very flexible allowing users to setup their
glance_api processes in as secure a method as possible.
The following process types are defined for glance_api:
glance_api_t
Note: semanage permissive -a glance_api_t can be used to make the
process type glance_api_t permissive. SELinux does not deny access to
permissive process types, but the AVC (SELinux denials) messages are
still generated.
BOOLEANS
SELinux policy is customizable based on least access required.
glance_api policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run glance_api with the tightest
access possible.
If you want to allow all daemons to write corefiles to /, you must turn
on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the
daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on
the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals,
you must turn on the daemons_use_tty boolean. Disabled by default.
setsebool -P daemons_use_tty 1
If you want to deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled by
default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors,
you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you
must turn on the domain_kernel_load_modules boolean. Disabled by
default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn
on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn
on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow confined applications to use nscd shared memory,
you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
MANAGED FILES
The SELinux process type glance_api_t can manage files labeled with the
following file types. The paths listed are the default paths for these
file types. Note the processes UID still need to have DAC permissions.
cluster_conf_t
/etc/cluster(/.*)?
cluster_var_lib_t
/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?
cluster_var_run_t
/var/run/crm(/.*)?
/var/run/cman_.*
/var/run/rsctmp(/.*)?
/var/run/aisexec.*
/var/run/heartbeat(/.*)?
/var/run/cpglockd.pid
/var/run/corosync.pid
/var/run/rgmanager.pid
/var/run/cluster/rgmanager.sk
glance_tmp_t
glance_var_lib_t
/var/lib/glance(/.*)?
glance_var_run_t
/var/run/glance(/.*)?
root_t

/initrd
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 glance_api policy is very flexible allowing users to setup
their glance_api processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the glance_api, if you
wanted to store files with these types in a diffent paths, you need to
execute the semanage command to sepecify alternate labeling and then
use restorecon to put the labels on disk.
semanage fcontext -a -t glance_api_exec_t '/srv/glance_api/con‐
tent(/.*)?'
restorecon -R -v /srv/myglance_api_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for glance_api:
glance_api_exec_t
- Set files with the glance_api_exec_t type, if you want to transition
an executable to the glance_api_t domain.
glance_api_initrc_exec_t
- Set files with the glance_api_initrc_exec_t type, if you want to
transition an executable to the glance_api_initrc_t domain.
Note: File context can be temporarily modified with the chcon command.
If you want to permanently 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.
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.
