The integrated button on the new unibody Macbooks presents a need to
report explicit four-finger actions. Evidently, the finger pressing
the button is also touching the trackpad, so in order to fully support
three-finger actions, the driver must be able to report four-finger
actions. This patch adds a new button, BTN_TOOL_QUADTAP, which
achieves this.

Running large cluster setup, we are hanging after many hours of
testing. Fixing this required going over the code and making sure the
rexmit entry was properly removed based on the cm_node's state and
packet received. Also when receiving a FIN packet, check seq# and
make sure there were no errors before calling handle_fin().
Following are the changes done in nes_cm.c:
* handle_ack_pkt() needs to return error value, so in case of error,
handle_fin() is not called. Some cleanup done while going over the code.
* handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing.
* process_packet(), in case of FIN only packet is received, call
check_seq() before processing.
* in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all
conditions, even if the packets need to be dropped.

This is a summery of the wire changes:
* OSDv2_ADDITIONAL_CDB_LENGTH == 192 => 228 (Total CDB is now 236 bytes)
* Attributes List Element Header grew, so attribute values are 8 bytes

OSD1's 20 bytes. This causes a couple of on-the-wire structures

In OSD2r05 draft each attribute list element header was changed
so attribute-value would be 8 bytes aligned. In OSD2r01-r04
it was aligned on 2 bytes. (This is because in OSD2r01 the complete
element was 8 bytes padded at end but the header was not adjusted
and caused permanent miss-alignment.)
OSD1 elements are not padded and might be or might not be aligned.
OSD1 is still supported.
In this code we do all the code re-factoring to separate OSD1/OSD2
differences but do not change actual wire format. All wire format
changes will happen in one patch later, for bisect-ability.

Diagnostic buffer support is already there in the driver. This support allows
applications to pull ring buffers from controller firmware for debugging
firmware related issues.
What this patch does is sends reqeust to firmware to release the buffers prior
to host reset. This will allow what ever debug info is there prior to reset
to be dma'd to host memory. With out this fix, some of the debug data would

The poison sanity check on the reply_post_free register needs to be by 32bit,
not 64bit. The poison check is there because its possible that the driver read
the 1st 32bit before the 2nd 32bit has been written to by firmware. In other
words, this handles race between driver reading the 64 bit register, and it
being dma'd across pci memory from controller firmware as two 32bit pci writes.

Rogue ports are currently not tracked on any list. The only reference
to them is through any outstanding exchanges pending on the rogue ports.
If the module is removed while a retry is set on a rogue port
(say a Plogi retry for instance), this retry is not cancelled because there
is no reference to the rogue port in the discovery rports list. Thus the
local port can clean itself up, delete the exchange pool, and then the
rogue port timeout can fire and try to start up another exchange.
This patch tracks the rogue ports in a new list disc->rogue_rports. Creating
a new list instead of using the disc->rports list keeps remote port code
change to a minimum.
1) Whenever a rogue port is created, it is immediately added to the
disc->rogue_rports list.
2) When the rogues port goes to ready, it is removed from the rogue list
and the real remote port is added to the disc->rports list
3) The removal of the rogue from the disc->rogue_rports list is done in
the context of the fc_rport_work() workQ thread in discovery callback.
4) Real rports are removed from the disc->rports list like before. Lookup
is done only in the real rports list. This avoids making large changes
to the remote port code.
5) In fc_disc_stop_rports, the rogues list is traversed in addition to the
real list to stop the rogue ports and issue logoffs on them. This way, rogue
ports get cleaned up when the local port goes away.
6) rogue remote ports are not removed from the list right away, but
removed late in fc_rport_work() context, multiple threads can find the same
remote port in the list and call rport_logoff(). Rport_logoff() only
continues with the logoff if port is not in NONE state, thus preventing
multiple logoffs and multiple list deletions.
7) Since the rport is removed from the disc list at a later stage
(in the disc callback), incoming frames can find the rport even if
rport_logoff() has been called on the rport. When rport_logoff() is called,
the rport state is set to NONE, and we are trying to cancel all exchanges
and retries on that port. While in this state, if an incoming
Plogi/Prli/Logo or other frames match the rport, we should not reply
because the rport is in the NONE state. Just drop the frame, since the
rport will be deleted soon in the disc callback (fc_rport_work)
8) In fc_disc_single(), remove rport lookup and call to fc_disc_del_target.
fc_disc_single() is called from recv_rscn_req() where rport lookup
and rport_logoff is already done.

For instance, if there is a Plogi pending (remote port is in Plogi state),
and the state changes to say NONE (because the port is being logged off),
then when the Plogi resp times out, do not start a retry.
This patch partially reverts an earlier patch (libfc: check for err when
recv and state is incorrect), by moving the state check back to before
checking for error. However, if the state does not match, then there is
an additional check to see if its an error ptr or a real frame before
jumping to err or out respectively.

gpn_ft_resp processing currently does not hold the discovery lock.
disc_done() thus gets called from gpn_ft_resp or from gpn_ft_parse
without the lock held. This then sets disc->pending to zero or calls
gpn_ft_req() without disc_lock held.
- Hold disc mutex during gpn_ft resp processing
- In disc_done, release the disc mutex while calling lport callback

we will want to drop the session, because it means we got a

This patch has us propogate the error upwards so libiscsi_tcp
or libiscsi can decide what the best action is to take. It

while holding it, because if iscsi_tcp drops the session in the
