sysadm_seunshare processes
DESCRIPTION
Security-Enhanced Linux secures the sysadm_seunshare processes via
flexible mandatory access control.
The sysadm_seunshare processes execute with the sysadm_seunshare_t
SELinux type. You can check if you have these processes running by exe‐
cuting the ps command with the -Z qualifier.
For example:
ps -eZ | grep sysadm_seunshare_t
ENTRYPOINTS
The sysadm_seunshare_t SELinux type can be entered via the seun‐
share_exec_t file type.
The default entrypoint paths for the sysadm_seunshare_t domain are the
following:
/usr/sbin/seunshare
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
sysadm_seunshare policy is very flexible allowing users to setup their
sysadm_seunshare processes in as secure a method as possible.
The following process types are defined for sysadm_seunshare:
sysadm_seunshare_t
Note: semanage permissive -a sysadm_seunshare_t can be used to make the
process type sysadm_seunshare_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux denials) mes‐
sages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required.
sysadm_seunshare policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run sysadm_seunshare 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
If you want to support fusefs home directories, you must turn on the
use_fusefs_home_dirs boolean. Disabled by default.
setsebool -P use_fusefs_home_dirs 1
If you want to support NFS home directories, you must turn on the
use_nfs_home_dirs boolean. Disabled by default.
setsebool -P use_nfs_home_dirs 1
If you want to support SAMBA home directories, you must turn on the
use_samba_home_dirs boolean. Disabled by default.
setsebool -P use_samba_home_dirs 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 sysadm_seunshare_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
sysadm_seunshare_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type sysadm_seunshare_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.
cgroup_t
/cgroup(/.*)?
/sys/fs/cgroup(/.*)?
sandbox_file_t
sandbox_tmpfs_type
all sandbox content in tmpfs file systems
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.
