Commit 9ead190b ("IB/uverbs: Don't serialize with ib_uverbs_idr_mutex")
rewrote how userspace objects are looked up in the uverbs module's
idrs, and introduced a severe bug in the process: there is no checking
that an operation is being performed by the right process any more.
Fix this by adding the missing check of uobj->context in __idr_get_uobj().
Apparently everyone is being very careful to only touch their own
objects, because this bug was introduced in June 2006 in 2.6.18, and
has gone undetected until now.

There is a justifying patch for Stephen's patches. Stephen's patches
disallows using a port range of one single port and brakes the meaning
of the 'remaining' variable, in some places it has different meaning.
My patch gives back the sense of 'remaining' variable. It should mean
how many ports are remaining and nothing else. Also my patch allows
using a single port.
I sure we must be able to use mentioned port range, this does not
restricted by documentation and does not brake current behavior.

Deadlock condition reported by Kanoj Sarcar <kanoj@netxen.com>.
The deadlock occurs when a connection request arrives at the same
time that a wildcard listen is being destroyed.
A wildcard listen maintains per device listen requests for each
RDMA device in the system. The per device listens are automatically
added and removed when RDMA devices are inserted or removed from
the system.
When a wildcard listen is destroyed, rdma_destroy_id() acquires
the rdma_cm's device mutex ('lock') to protect against hot-plug
events adding or removing per device listens. It then tries to
destroy the per device listens by calling ib_destroy_cm_id() or
iw_destroy_cm_id(). It does this while holding the device mutex.
However, if the underlying iw/ib CM reports a connection request
while this is occurring, the rdma_cm callback function will try
to acquire the same device mutex. Since we're in a callback,
the ib_destroy_cm_id() or iw_destroy_cm_id() calls will block until
their callback thread returns, but the callback is blocked waiting for
the device mutex.
Fix this by re-working how per device listens are destroyed. Use
rdma_destroy_id(), which avoids the deadlock, in place of
cma_destroy_listen(). Additional synchronization is added to handle
device hot-plug events and ensure that the id is not destroyed twice.

If a user allocates a QP on an rdma_cm_id, the rdma_cm will automatically
transition the QP through its states (RTR, RTS, error, etc.) While the
QP state transitions are occurring, the QP itself must remain valid.
Provide locking around the QP pointer to prevent its destruction while
accessing the pointer.
This fixes an issue reported by Olaf Kirch from Oracle that resulted in
a system crash:
"An incoming connection arrives and we decide to tear down the nascent
connection. The remote ends decides to do the same. We start to shut
down the connection, and call rdma_destroy_qp on our cm_id. ... Now
apparently a 'connect reject' message comes in from the other host,
and cma_ib_handler() is called with an event of IB_CM_REJ_RECEIVED.
It calls cma_modify_qp_err, which for some odd reason tries to modify
the exact same QP we just destroyed."

Automatically queue MRA message to decrease the number of retries sent

The IB CM provides a message received acknowledged (MRA) message that
can be sent to indicate that a REQ or REP message has been received, but
will require more time to process than the timeout specified by those
messages. In many cases, the application may not know how long it will
take to respond to a CM message, but the majority of the time, it will
usually respond before a retry has been sent. Rather than sending an
MRA in response to all messages just to handle the case where a longer
timeout is needed, it is more efficient to queue the MRA for sending in
case a duplicate message is received.
This avoids sending an MRA when it is not needed, but limits the number
of times that a REQ or REP will be resent. It also provides for a
simpler implementation than generating the MRA based on a timer event.
(That is, trying to send the MRA after receiving the first REQ or REP if
a response has not been generated, so that it is received at the remote
side before a duplicate REQ or REP has been received)

The declaration of struct ib_user_mad_reg_req.method_mask[] exported
to userspace was an array of __u32, but the kernel internally treated
it as a bitmap made up of longs. This makes a difference for 64-bit
big-endian kernels, where numbering the bits in an array of__u32 gives:
|31.....0|63....31|95....64|127...96|
while numbering the bits in an array of longs gives:
|63..............0|127............64|
64-bit userspace can handle this by just treating method_mask[] as an
array of longs, but 32-bit userspace is really stuck: the meaning of
the bits in method_mask[] depends on whether the kernel is 32-bit or
64-bit, and there's no sane way for userspace to know that.
Fix this by updating <rdma/ib_user_mad.h> to make it clear that
method_mask[] is an array of longs, and using a compat_ioctl method to
convert to an array of 64-bit longs to handle the 32-on-64 problem.
This fixes the interface description to match existing behavior (so
working binaries continue to work) in almost all situations, and gives
consistent semantics in the case of 32-bit userspace that can run on
either a 32-bit or 64-bit kernel, so that the same binary can work for
both 32-on-32 and 32-on-64 systems.

Add support for setting the P_Key index of sent MADs and getting the
P_Key index of received MADs. This requires a change to the layout of
the ABI structure struct ib_user_mad_hdr, so to avoid breaking
compatibility, we default to the old (unchanged) ABI and add a new
ioctl IB_USER_MAD_ENABLE_PKEY that allows applications that are aware
of the new ABI to opt into using it.
We plan on switching to the new ABI by default in a year or so, and
this patch adds a warning that is printed when an application uses the
old ABI, to push people towards converting to the new ABI.

I was looking at the code for multicast.c and noticed that
ib_sa_join_multicast() calls queue_join() which puts the
request at the front of the group->pending_list. If this
is a second request, it seems like it would interfere with
process_join_error() since group->last_join won't point
to the member at the head of the pending_list. The sequence
would thus be:
1. ib_sa_join_multicast()
puts member1 on head of pending_list and starts work thread
2. mcast_work_handler()
calls send_join() which sets group->last_join to member1
3. ib_sa_join_multicast()
puts member2 on head of pending_list
4. join operation for member1 receives failures response from SA.
5. join_handler() is called with error status
6. process_join_error() fails to process member1 since
it doesn't match the first entry in the group->pending_list.
The impact is that the failed join request is tossed. The second
request is processed, and after it completes, the original request ends
up being retried.
This change also results in join requests being processed in FIFO
order.

ib_find_pkey() is used as a replacement for ib_find_cached_pkey(), and
the original function ignored the membership bit when searching for a

In particular, IPoIB turns on the P_Key membership bit of limited
membership P_Keys when creating a child interface and looks for the
full membership P_key. This broke if a port was a partial member of a

as start_id. This fails to generate distinct ids if
1. An id is constantly created and destroyed
2. A chunk of ids just beyond the current next_id value is occupied
This in turn leads to an increased chance of connection request being
mis-detected as a duplicate, sometimes for several retries, until
next_id gets past the block of allocated ids. This has been observed
in practice.
As a fix, remember the last id allocated and start immediately above it.

function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.
This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
they don't need sched.h
b) sched.h stops being dependency for significant number of files:
