NAME

svc_run_selinux - Security Enhanced Linux Policy for the svc_run processes

DESCRIPTION

Security-Enhanced Linux secures the svc_run processes via flexible mandatory access control.

The svc_run processes execute with the svc_run_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 svc_run_t

ENTRYPOINTS

The svc_run_t SELinux type can be entered via the svc_run_exec_t file type.

The default entrypoint paths for the svc_run_t domain are the following:

/var/service/.*/run.*, /var/service/.*/log/run, /var/qmail/supervise/.*/run, /var/qmail/supervise/.*/log/run, /usr/bin/envdir, /usr/bin/fghack, /usr/bin/setlock, /var/axfrdns/run, /var/tinydns/run, /usr/bin/pgrphack, /var/dnscache/run, /usr/bin/envuidgid, /usr/bin/setuidgid, /usr/bin/softlimit, /var/axfrdns/log/run, /var/tinydns/log/run, /var/dnscache/log/run

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 psP Policy governs the access confined processes have to files. SELinux svc_run policy is very flexible allowing users to setup their svc_run processes in as secure a method as possible.

The following process types are defined for svc_run:

svc_run_t

Note: semanage permissive -a svc_run_t can be used to make the process type svc_run_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. svc_run policy is extremely flexible and has several booleans that allow you to manipulate the policy and run svc_run with the tightest access possible.

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

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 lsP Policy governs the access confined processes have to these files. SELinux svc_run policy is very flexible allowing users to setup their svc_run processes in as secure a method as possible.

The following file types are defined for svc_run:

svc_run_exec_t

- Set files with the svc_run_exec_t type, if you want to transition an executable to the svc_run_t domain.

Paths:: /var/service/.*/run.*, /var/service/.*/log/run, /var/qmail/supervise/.*/run, /var/qmail/supervise/.*/log/run, /usr/bin/envdir, /usr/bin/fghack, /usr/bin/setlock, /var/axfrdns/run, /var/tinydns/run, /usr/bin/pgrphack, /var/dnscache/run, /usr/bin/envuidgid, /usr/bin/setuidgid, /usr/bin/softlimit, /var/axfrdns/log/run, /var/tinydns/log/run, /var/dnscache/log/run

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 database. 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 policy modules.

semanage boolean can also be used to manipulate the booleans

system-config-selinux is a GUI tool available to customize SELinux policy settings.
