Commit e88c9271d9f8 ("IB/hfi1: Fix buffer cache corner case which
may cause corruption") introduced a bug which may cause a reference
count of a interval RB node to be leaked in the case where an SDMA
transfer from that node completes at the same time as the node is
being extended.
If a node is being extended, it is first removed from the RB tree
in order to be processed without the risk of an invalidation event
removing the node at the same time.
If a SDMA completion happens during that time, the completion handler
will fail to find the node in the RB tree and, therefore, fail to
correctly decrement its refcount. This leaves the node in the tree and
its pages pinned for the duration of the user process.
To prevent this from happening the io vector adds a reference to the
RB node, which is used during the SDMA completion instead of looking
up the node in the RB tree.
This change adds a performance improvement as a side effect by avoiding
the RB tree lookup.
Fixes: e88c9271d9f8 ("IB/hfi1: Fix buffer cache corner case which may cause corruption")

If one iteration of the loop causes an error return and a later iteration
doesn't, the later iteration causes the earlier error condition to be

The interval RB tree management functions use handlers to
store user-specific callback for the various tree operations.
These handlers are put on a doubly-linked list. When a RB
tree function is called, the list is searched for the handler
of the particular tree.
The list which holds the handlers is modified very rarely - when
a handler is created and when a handler is removed. On the other
hand, it is searched very often. This a perfect usage scenario
for RCU.
The result is a much lower overhead of traversing the list as most
of the time no locking will be required.

The function level reset in init_chip() and subsequent write of all 1s
to the ASIC_QSFP registers effectively resets attached active and
optical QSFP modules that pay attention to the RESET_N pin.
We subsequently try to access the QSFP management interface to qualify
and tune the channel and fabric SerDes before enough time (2 seconds
per SFF 8679 spec for QSFP28 modules) has elapsed for the module to
finish initialization. This fails and causes the failure of the channel
tuning algorithm, preventing us from bringing the link up.
This patch checks the port type prior to beginning channel and SerDes
tuning, and if found to be QSFP, watches for the QSFP initialization
complete interrupt, with a maximum timeout of 2 seconds, to allow the
initialization to complete.

* Add mlcr, pcmr and mcia registers for dump module EEPROM
* Add support for FCS, beacon led and disable_link bits to

* Add CQE period mode bit in CQ context for CQE based CQ
moderation support
* Add umr SQ bit for fragmented memory registration
* Add needed bits and caps for Striding RQ support
In-order to avoid possible future conflicts between rdma and
net-next we added all expected updates to this file for this release.
If more changes will be submitted, we plan to do it only through
one of the subsystems, probably net-next.

In rx_data(), with the ep in FPDU_MODE, refcnt=2, if we get unexpected
streaming data, we call c4iw_modify_rc_qp() and move the qp from
RTS -> TERMINATE. In c4iw_modify_rc_qp(), if rdma_fini() returns
an error, the ep will be dereferenced (refcnt=1). Then rx_data()
calls c4iw_ep_disconnect() which starts the close operation.
But if send_halfclose() fails in c4iw_ep_disconnect(), we will call
release_ep_resources() derefing the ep which reduces the refcnt to 0 and
and frees the ep. However we still has the ep mutex at that point, so we
have a touch-after-free bug. There is a similar issue where
peer_close() calls c4iw_ep_disconnect().
The solution is to add a reference to the ep in c4iw_ep_disconnect()
after acquiring the mutex, and release it after releasing the mutex.

In c4iw_ep_disconnect(), if we start the ep timer to begin a close,
but send_halfclose() fails, we need to stop the timer and send a CLOSE

crash when the ep timer fires if the ep is referencing a previous instance
of the device. This can happen as part of adapter reset/recovery, for
instance.

If ARP fails before the CPL_PASS_ACCEPT_RPL is seen by hardware, the tid
will be stuck in SYN_PEND and never released. So create an arp failure
handler specifically for this message to release the endpoint resources.
In pass_accept_rpl_arp_failure(), put the parent endpoint so it will
be freed when destroyed. Also we don't need to call release_tid() here
because _c4iw_free_ep() calls cxgb4_remove_tid() which releases the
hwtid.
If we get an ABORT_REQ_RSS instead of a PASS_ESTABLISH (because the
peer's ACK to our SYN is never received), then put the parent as well
in peer_abort().
Treat accept_cr() failures just like arp failures: put the parent ep
and release the ep resources destroying the tid
The ARP failure handlers are called in an atomic context, so we need to
schedule some of the processing which might block. Namely _c4iw_free_ep()
which needs a mutex. So create a "special" CPL opcode and handler and
schedule it via sched() to be run by process_work() in a blockable context.
Also rework the active open arp failure handler to make use of
release_ep_resources(). This allows both the active and passive arp
failure handlers to use the same deferred cleanup function.

iSER currently has a couple places that set max_sectors in either the host
template or SCSI host, and all of them get it wrong.
This patch instead uses a single assignment that (hopefully) gets it right:
the max_sectors value must be derived from the number of segments in the
FR or FMR structure, but actually be one lower than the page size multiplied
by the number of sectors, as it has to handle the case of non-aligned I/O.
Without this I get trivial to reproduce hangs when running xfstests
(on XFS) over iSER to Linux targets.
