setroubleshoot_fixit processes
DESCRIPTION
Security-Enhanced Linux secures the setroubleshoot_fixit processes via
flexible mandatory access control.
The setroubleshoot_fixit processes execute with the setrou‐
bleshoot_fixit_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 setroubleshoot_fixit_t
ENTRYPOINTS
The setroubleshoot_fixit_t SELinux type can be entered via the setrou‐
bleshoot_fixit_exec_t file type.
The default entrypoint paths for the setroubleshoot_fixit_t domain are
the following:
/usr/share/setroubleshoot/SetroubleshootFixit.py*
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
setroubleshoot_fixit policy is very flexible allowing users to setup
their setroubleshoot_fixit processes in as secure a method as possible.
The following process types are defined for setroubleshoot_fixit:
setroubleshoot_fixit_t
Note: semanage permissive -a setroubleshoot_fixit_t can be used to make
the process type setroubleshoot_fixit_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. setrou‐
bleshoot_fixit policy is extremely flexible and has several booleans
that allow you to manipulate the policy and run setroubleshoot_fixit
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 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 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 setroubleshoot_fixit_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
setroubleshoot_fixit_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type setroubleshoot_fixit_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
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 setroubleshoot_fixit policy is very flexible allowing users to
setup their setroubleshoot_fixit processes in as secure a method as
possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the setroubleshoot_fixit, 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 setroubleshoot_fixit_exec_t '/srv/setrou‐
bleshoot_fixit/content(/.*)?'
restorecon -R -v /srv/mysetroubleshoot_fixit_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for setroubleshoot_fixit:
setroubleshoot_fixit_exec_t
- Set files with the setroubleshoot_fixit_exec_t type, if you want to
transition an executable to the setroubleshoot_fixit_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.
