ibft: Expose iBFT acpi header via sysfs

2016-05-16T15:14:29Z

Some ethernet adapter vendors are supplying products which support optional (payed license) features. On some adapters this includes a hardware iscsi initiator. The same adapters in a normal (no extra licenses) mode of operation can be used as a software iscsi initiator. In addition, software iscsi boot initiators are becoming a standard part of many vendors uefi implementations. This is creating difficulties during early boot/install determining the proper configuration method for these adapters when they are used as a boot device. The attached patch creates sysfs entries to expose information from the acpi header of the ibft table. This information allows for a method to easily determining if an ibft table was created by a ethernet card's firmware or the system uefi/bios. In the case of a hardware initiator this information in combination with the pci vendor and device id can be used to ascertain any vendor specific behaviors that need to be accommodated.

iscsi_ibft: Add prefix-len attr and display netmask

2016-05-16T15:14:23Z

The iBFT table only specifies a prefix length, not a netmask. And the netmask is pretty much pointless for IPv6. So introduce a new attribute 'prefix-len'. Some older user-space code might rely on the netmask attribute being present, so we should always display it.

[SCSI] iscsi_ibft, be2iscsi, iscsi_boot: fix boot kobj data lifetime management

2011-06-29T21:43:06Z

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 interface

2010-05-11T17:02:38Z

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. Signed-off-by: Mike Christie Signed-off-by: Konrad Rzeszutek Wilk Signed-off-by: Peter Jones
