iSCSI must support software iscsi (iscsi_tcp, iser), hardware iscsi (qla4xxx), and partial offload (broadcom). To be able to allow each stack or driver or port (virtual or physical) to be able to log into the same target portal we use the initiator tuple [[HWADDRESS | NETDEVNAME], INITIATOR_NAME] and the target tuple [TARGETNAME, CONN_ADDRESS, CONN_PORT] to id a session. This patch adds the netdev name, which is used by software iscsi when it binds a session to a netdevice using the SO_BINDTODEVICE sock opt. It cannot use HWADDRESS because if someone did vlans then the same netdevice will have the same mac and the initiator,target id will not be unique. Signed-off-by:

This patch exports the local address for the session. For qla4xxx this is the ip of the hba's port. For software this is the src addr of the socket. Signed-off-by:

This patch should fix the file descriptor leak problem. A quick look through the kernel shows that users of sockfd_lookup use sockfd_put to release their handle. We were using sock_release which from the comments and code look like it does not release the get() on the file from the lookup. Signed-off-by:

Userspace will want to know what the driver/FW/HW capabilites when it comes to some operations like if the hardware can do discovery or if it can store iscsi info like what target was used for boot. This patch adds some new caps so userspace can tell if the driver supports hardware/fw based sendtargets discovery and if the hardware has some flash which may be holding or can contain some iscsi target info .

If we got the padding, data and header in different skbs, we were not handling the padding correctly because we attributed it to the data's skb. This resulted in the initiator reading from pad bytes + skb offset instead of the correct offset. If you could not connect with the open solaris target, this will fix the lock up problem you were hitting. Signed-off-by:

This patch allows us to set can_queue and cmds_per_lun from userspace when we create the session/host. From there we can set it on a per target basis. The patch fully converts iscsi_tcp, but only hooks up ib_iser for cmd_per_lun since it currently has a lots of preallocations based on can_queue. Signed-off-by:

The cmdsn allocation and pdu transmit code can race, and we can end up sending a pdu with cmdsn 10 before a pdu with 5. The target will then fail the connection/session. This patch fixes the problem by delaying the cmdsn allocation until we are about to send the pdu. This also removes the xmitmutex. We were using the connection xmitmutex during error handling to handle races with mtask and ctask cleanup and completion. For ctasks we now have nice refcounting and for the mtask, if we hit the case where the mtask timesout and it is floating around somewhere in the driver, we end up dropping the session. And to handle session level cleanup, we use the xmit suspend bit along with scsi_flush_queue and the session lock to make sure that the xmit thread is not possibly transmitting a task while we are trying to kill it.

If iscsi_tcp partially sends a header, it would recalculate the header size and readd the size of the digest (if header digests are used).This would cause us to send sizeof(digest) extra bytes when we sent the rest of the header. Signed-off-by:

The attached patches add sysfs files for the chap settings to the iscsi transport class, iscsi_tcp and ib_iser. This is needed for software iscsi because there are times when iscsid can die and it will need to reread the values it was using. And it is needed by qla4xxx for basic management opertaions. This patch does not hook in qla4xxx yet, because I am not sure the mbx command to use. Signed-off-by:

This patch fixes handling of expected datasn/r2tsn as received from target. It is done according to: T10 rfc3720 section 3.2.2.3. Data Sequencing. . unify expected datasn/r2tsn into one counter . calculate than check expected datasn/r2tsn. On error print a message and fail the request. (TODO use iscsi retransmits) . remove the FIXME ;) . avoid zero length memset Signed-off-by:

For iscsi root boot, software iscsi needs to know what the BIOS/OF initiator used for the initiator name so this puts it in sysfs for userspace to be able to pick up. For hw iscsi, it is nice to see what the card is using. This patch adds the new param, and hooks in qla4xxx, iscsi_tcp, and ib_iser. Signed-off-by:

Currently accessing the scsi host private data is rather messy because it comes as an unsigned long that always needs a cast first. This patch introduces a helper that does the cast called shost_priv. It's similar in spirit to netdev_priv for network drivers. This is the first patch introducing the macro, and the second patch in the series will convert esp and it's subdrivers as an example. Further conversion will wait until the helper is in the tree to make patch juggling easier. Signed-off-by:

The current code is leaking a reference to dreq->kref when the calls to nfs_direct_read_schedule() and nfs_direct_write_schedule() return an error. This patch moves the call to kref_put() from nfs_direct_wait() back into nfs_direct_read() and nfs_direct_write() (which are the functions that actually took the reference in the first place) fixing the leak. Thanks to Denis V. Lunev for spotting the bug and proposing the original fix. Acked-by:
