Add the opportunity to globally specify multiple addresses, which iSCSI/iSER portal will listen on. There is a way to specify the addresses for a target, on which portals it will be available, using the allowed_portal parameter. There is also a way to set this globally via the iscsi-scstd --address parameter. The problem is that the last option allows you to specify only one local address. So extend this functionality to specify more then one address. Also increase the maximum number of listening addresses to 32. Signed-off-by: Aleksandr Dyadyushkin <alextalker@ya.ru>

.SH KNOWN ISSUES
|
|
Task attributes is incomplete (all tasks are treated as if they have the SIMPLE attribute.)
|
|
|
|
SCSI task management is incomplete.
|
|
|
|
NOP-In is incomplete.
|
|
|
|
The target never sends a NOP-In of its own accord.
|
|
|
|
Header and Data Digest in a discovery session are not implemented.
|
|
|
|
Out-of-memory situation leads to the system crash (There are still some out-of-memory bugs.)
