telepathy_stream_engSELinuxiPolicy telepathytelepathy_stream_engine_selinux(8)NAMEtelepathy_stream_engine_selinux - Security Enhanced Linux Policy for
the telepathy_stream_engine processes
DESCRIPTION
Security-Enhanced Linux secures the telepathy_stream_engine processes
via flexible mandatory access control.
The telepathy_stream_engine processes execute with the telepa‐
thy_stream_engine_t SELinux type. You can check if you have these pro‐
cesses running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep telepathy_stream_engine_t
ENTRYPOINTS
The telepathy_stream_engine_t SELinux type can be entered via the
telepathy_stream_engine_exec_t file type.
The default entrypoint paths for the telepathy_stream_engine_t domain
are the following:
/usr/libexec/telepathy-stream-engine
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
telepathy_stream_engine policy is very flexible allowing users to setup
their telepathy_stream_engine processes in as secure a method as possi‐
ble.
The following process types are defined for telepathy_stream_engine:
telepathy_stream_engine_t
Note: semanage permissive -a telepathy_stream_engine_t can be used to
make the process type telepathy_stream_engine_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. telepa‐
thy_stream_engine policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run telepathy_stream_engine
with the tightest access possible.
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server, you must turn on the authlo‐
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 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 run with kerberos, you
must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 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
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from
ldap rather then using a sssd server for the telepathy_stream_engine_t,
you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
telepathy_stream_engine_t, you must turn on the kerberos_enabled bool‐
ean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type telepathy_stream_engine_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.
cache_home_t
/root/.cache(/.*)?
/home/[^/]*/.nv(/.*)?
/home/[^/]*/.cache(/.*)?
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 telepathy_stream_engine policy is very flexible allowing users
to setup their telepathy_stream_engine processes in as secure a method
as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the telepathy_stream_engine,
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 telepathy_stream_engine_exec_t '/srv/telepa‐
thy_stream_engine/content(/.*)?'
restorecon -R -v /srv/mytelepathy_stream_engine_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for telepathy_stream_engine:
telepathy_stream_engine_exec_t
- Set files with the telepathy_stream_engine_exec_t type, if you want
to transition an executable to the telepathy_stream_engine_t domain.
telepathy_stream_engine_tmp_t
- Set files with the telepathy_stream_engine_tmp_t type, if you want to
store telepathy stream engine temporary files in the /tmp directories.
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.
