irssi_selinux(8) - Linux man page

Name

irssi_selinux - Security Enhanced Linux Policy for the irssi processes

Description

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

The irssi processes execute with the irssi_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 irssi_t

Entrypoints

The irssi_t SELinux type can be entered via the "irssi_exec_t" file type. The default entrypoint paths for the irssi_t domain are the following:"

/usr/bin/irssi

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

The following process types are defined for irssi:

irssi_t

Note: semanage permissive -a irssi_t

can be used to make the process type irssi_t permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

Booleans

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

If you want to allow the Irssi IRC Client to connect to any port, and to bind to any unreserved port, you must turn on the irssi_use_full_network boolean.

setsebool -P irssi_use_full_network 1

If you want to allow the Irssi IRC Client to connect to any port, and to bind to any unreserved port, you must turn on the irssi_use_full_network boolean.

setsebool -P irssi_use_full_network 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 ls

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

The following file types are defined for irssi:

irssi_etc_t

- Set files with the irssi_etc_t type, if you want to store irssi files in the /etc directories.

irssi_exec_t

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

irssi_home_t

- Set files with the irssi_home_t type, if you want to store irssi files in the users home 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.

Managed Files

The SELinux process type irssi_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.

initrc_tmp_t

irssi_home_t

/home/[^/]*/.irssi(/.*)?

mnt_t

/mnt(/[^/]*)

/mnt(/[^/]*)?

/rhev(/[^/]*)?

/media(/[^/]*)

/media(/[^/]*)?

/etc/rhgb(/.*)?

/media/.hal-.*

/net

/afs

/misc

/rhev

nfs_t

tmp_t

/tmp

/usr/tmp

/var/tmp

/var/tmp/vi.recover

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.
