ISCSID(8) BSD System Manager's Manual ISCSID(8)NAME
iscsid -- iSCSI initiator daemon
SYNOPSIS
iscsid [-P pidfile] [-d] [-l loglevel] [-m maxproc] [-t seconds]
DESCRIPTION
The iscsid daemon is responsible for performing the Login Phase of iSCSI connections, as well as performing SendTargets discovery.
Upon startup, the iscsid daemon opens the iSCSI initiator device file and waits for kernel requests. iscsid does not use any configuration
files. All needed information is supplied by the kernel.
When the iscsid daemon is not running, already established iSCSI connections continue to work. However, establishing new connections, or
recovering existing ones in case of connection error, is not possible.
The following options are available:
-P pidfile Specify alternative location of a file where main process PID will be stored. The default location is /var/run/iscsid.pid.
-d Debug mode. The server sends verbose debug output to standard error, and does not put itself in the background. The server will
also not fork and will exit after processing one connection. This option is only intended for debugging the initiator.
-l loglevel
Specifies debug level. The default is 0.
-m maxproc Specifies limit for concurrently running child processes handling connections. The default is 30. Setting it to 0 disables the
limit.
-t seconds Specifies timeout for login session, after which the connection will be forcibly terminated. The default is 60. Setting it to 0
disables the timeout.
FILES
/dev/iscsi The iSCSI initiator device file.
/var/run/iscsid.pid The default location of the iscsid PID file.
EXIT STATUS
The iscsid utility exits 0 on success, and >0 if an error occurs.

The iscsid command appeared in FreeBSD 10.0.
AUTHORS
The iscsid utility was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.

iscsid_selinux(8) SELinux Policy iscsid iscsid_selinux(8)NAME
iscsid_selinux - Security Enhanced Linux Policy for the iscsid processes
DESCRIPTION
Security-Enhanced Linux secures the iscsid processes via flexible mandatory access control.
The iscsid processes execute with the iscsid_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 iscsid_t
ENTRYPOINTS
The iscsid_t SELinux type can be entered via the iscsid_exec_t file type.
The default entrypoint paths for the iscsid_t domain are the following:
/sbin/iscsid, /sbin/iscsiuio, /usr/sbin/iscsid, /usr/sbin/iscsiuio, /usr/sbin/iscsiadm
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 iscsid policy is very flexible allowing users to setup their iscsid
processes in as secure a method as possible.
The following process types are defined for iscsid:
iscsid_t
Note: semanage permissive -a iscsid_t can be used to make the process type iscsid_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. iscsid policy is extremely flexible and has several booleans that allow you
to manipulate the policy and run iscsid 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. Enabled 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 iscsid_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 iscsid_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux iscsid policy is very flexible allowing users to setup their
iscsid processes in as secure a method as possible.
The following port types are defined for iscsid:
iscsi_port_t
Default Defined Ports:
tcp 3260
MANAGED FILES
The SELinux process type iscsid_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(/.*)?

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 iscsid policy is very flexible allowing users to setup their
iscsid processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the iscsid, if you wanted to store files with these types in a diffent paths, you need to exe-
cute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t iscsid_exec_t '/srv/iscsid/content(/.*)?'
restorecon -R -v /srv/myiscsid_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for iscsid:
iscsid_exec_t
- Set files with the iscsid_exec_t type, if you want to transition an executable to the iscsid_t domain.
Paths:
/sbin/iscsid, /sbin/iscsiuio, /usr/sbin/iscsid, /usr/sbin/iscsiuio, /usr/sbin/iscsiadm
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 port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
