NAME

qmail_start_selinux - Security Enhanced Linux Policy for the qmail_start processes

DESCRIPTION

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

The qmail_start processes execute with the qmail_start_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 qmail_start_t

ENTRYPOINTS

The qmail_start_t SELinux type can be entered via the qmail_start_exec_t file type.

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

/var/qmail/bin/qmail-start

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 qmail_start policy is very flexible allowing users to setup their qmail_start processes in as secure a method as possible.

The following process types are defined for qmail_start:

qmail_start_t

Note: semanage permissive -a qmail_start_t can be used to make the process type qmail_start_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. qmail_start policy is extremely flexible and has several booleans that allow you to manipulate the policy and run qmail_start 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

MANAGED FILES

The SELinux process type qmail_start_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/corosync-qnetd(/.*)?

       /var/run/corosync-qdevice(/.*)?

       /var/run/corosync.pid

       /var/run/cpglockd.pid

       /var/run/rgmanager.pid

       /var/run/cluster/rgmanager.sk

root_t

        /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?

       /

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

The following file types are defined for qmail_start:

qmail_start_exec_t

- Set files with the qmail_start_exec_t type, if you want to transition an executable to the qmail_start_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 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.
