qatlib_selinux - Man Page

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

The qatlib processes execute with the qatlib_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 qatlib_t

The qatlib_t SELinux type can be entered via the qatlib_exec_t file type.

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

/usr/bin/qatmgr, /usr/bin/qat_init.sh

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 psbP

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

The following process types are defined for qatlib:

qatlib_t

Note: semanage permissive -a qatlib_t can be used to make the process type qatlib_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

SELinux policy is customizable based on least access required.  qatlib policy is extremely flexible and has several booleans that allow you to manipulate the policy and run qatlib with the tightest access possible.

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 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 disable kernel module loading, you must turn on the secure_mode_insmod boolean. Disabled by default.

setsebool -P secure_mode_insmod 1

The SELinux process type qatlib_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(/.*)?

/var/lib/pcsd(/.*)?

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 lsbP

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the qatlib, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t qatlib_exec_t '/srv/qatlib/content(/.*)?'
restorecon -R -v /srv/myqatlib_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for qatlib:

qatlib_conf_t

- Set files with the qatlib_conf_t type, if you want to treat the files as qatlib configuration data, usually stored under the /etc directory.

qatlib_exec_t

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

Paths:

/usr/bin/qatmgr, /usr/bin/qat_init.sh

qatlib_unit_file_t

- Set files with the qatlib_unit_file_t type, if you want to treat the files as qatlib unit content.

qatlib_var_run_t

- Set files with the qatlib_var_run_t type, if you want to store the qatlib files under the /run or /var/run directory.

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.

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.
