* [SCSI] iscsi_ibft, be2iscsi, iscsi_boot: fix boot kobj data lifetime managementMike Christie2011-06-291-3/+13
| | | | | | | | | | | | | | | | be2iscsi passes the boot functions its phba object which is allocated in the shost, but iscsi_ibft passes in a object allocated for each item to display. The problem is that iscsi_boot_sysfs was managing the lifetime of the object passed in and doing a kfree on release. This causes a double free for be2iscsi which frees the shost in its pci_remove. This patch fixes the problem by adding a release callback which the drivers can call kfree or a put() type of function (needed for be2iscsi which will do a get/put on the shost).

* ibft: separate ibft parsing from sysfs interfaceMike Christie2010-05-111-0/+123
Not all iscsi drivers support ibft. For drivers like be2iscsi that do not but are bootable through a vendor firmware specific format/process this patch moves the sysfs interface from the ibft code to a lib module. This then allows userspace tools to search for iscsi boot info in a common place and in a common format. ibft iscsi boot info is exported in the same place as it was before: /sys/firmware/ibft. vendor/fw boot info gets export in /sys/firmware/iscsi_bootX, where X is the scsi host number of the HBA. Underneath these parent dirs, the target, ethernet, and initiator dirs are the same as they were before.
