This patch prevents a UC QP to be created attached to an SRQ, since
current firmware does not support this feature.

This patch makes the IV generators use the new RNG interface so
that the user can pick an RNG other than the default get_random_bytes.

This patch adds a random number generator interface as well as a
cryptographic pseudo-random number generator based on AES. It is
meant to be used in cases where a deterministic CPRNG is required.
One of the first applications will be as an input in the IPsec IV
generation process.

Add the ability to turn FIPS-compliant mode on or off at boot
In order to be FIPS compliant, several check may need to be preformed that may
be construed as unusefull in a non-compliant mode. This patch allows us to set
a kernel flag incating that we are running in a fips-compliant mode from boot
up. It also exports that mode information to user space via a sysctl
(/proc/sys/crypto/fips_enabled).
Tested successfully by me.

As it is we only test ciphers when combined with a mode. That means
users that do not invoke a mode of operations may get an untested
cipher.
This patch tests all ciphers using the ECB mode so that simple cipher
users such as ansi-cprng are also protected.

This patch creates a new interface algorithm testing. A test can
be requested for a particular implementation of an algorithm. This
is achieved by taking both the name of the algorithm and that of
the implementation.
The all-inclusive test has also been rewritten to no longer require
a duplicate listing of all algorithms with tests. In that process
a number of missing tests have also been discovered and rectified.

The info printed is a complete waste of space when there is no error
since it doesn't tell us anything that we don't already know. If there
is an error, we can also be more verbose.
In case that there is an error, this patch also aborts the test and
returns the error to the caller. In future this will be used to
algorithms at registration time.

From NHM processor onward, Intel processors can support hardware accelerated
CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set.
The patch detects the availability of the feature, and chooses the most proper
way to calculate CRC32c checksum.
Byte code instructions are used for compiler compatibility.
No MMX / XMM registers is involved in the implementation.

If tcrypt is to be used as a run-time integrity test, it needs to be
more resilient in a hostile environment. For a start allocating 32K
of physically contiguous memory is definitely out.
This patch teaches it to use separate pages instead.

Back in prehistoric (pre-git!) days, the kernel's MSI-X support did
request_mem_region() on a device's MSI-X tables, which meant that a
driver that enabled MSI-X couldn't use pci_request_regions() (since
that would clash with the PCI layer's MSI-X request).
However, that was removed (by me!) years ago, so mthca can just use
pci_request_regions() and pci_release_regions() instead of its own
much more complicated code that avoids requesting the MSI-X tables.

Currently, IPoIB is an LLTX driver that uses its own IRQ-disabling
tx_lock. Not only do we want to get rid of LLTX, this actually causes
problems because of the skb_orphan() done with this tx_lock held: some
skb destructors expect to be run with interrupts enabled.
The simplest fix for this is to get rid of the driver-private tx_lock
and stop using LLTX. We kill off priv->tx_lock and use
netif_tx_lock[_bh]() instead; the patch to do this is a tiny bit
tricky because we need to update places that take priv->lock inside
the tx_lock to disable IRQs, rather than relying on tx_lock having
already disabled IRQs.
Also, there are a couple of places where we need to disable BHs to
make sure we have a consistent context to call netif_tx_lock() (since
we no longer can use _irqsave() variants), and we also have to change
ipoib_send_comp_handler() to call drain_tx_cq() through a timer rather
than directly, because ipoib_send_comp_handler() runs in interrupt
context and drain_tx_cq() must run in BH context so it can call
netif_tx_lock().

Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM
change events") changed how paths are flushed on an SM event. This
change introduces a problem if the path record query triggered by
fails, causing path->ah to become NULL. A later successful path query
will then trigger WARN_ON() in path_rec_completion(), and crash
because path->ah has already been freed, so the ipoib_put_ah() inside
the lock in path_rec_completion() may actually drop the last reference
(contrary to the comment that claims this is safe).
Fix this by updating path->ah and freeing old_ah only when the path
record query is successful. This prevents the neighbour AH and that
path AH from getting out of sync.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1194>

When a QP goes into error state, it is required that CQ entries with a
flush error status are delivered to the application for any
outstanding work requests. eHCA does not do this in hardware, so this
patch adds software flush CQE generation to the ehca driver.
Whenever a QP gets into error state, it is added to the QP error list
of its respective CQ. If the error QP list of a CQ is not empty,
poll_cq() generates flush CQEs before polling the actual CQ.

When running ibv_devinfo, the active_mtu returned is garbage. This is
due to the field not being populated in the query_port function in the
driver. The patch below populates the active_mtu field with a MTU of
2k. It also zeros the struct, so that any new additions to it will
return 0.

commit 110cf374 ("infiniband: make cm_device use a struct device and
not a kobject.") introduced a memory leak, since it deleted
cm_release_dev_obj(), which was where cm_dev was freed. Fix this by
freeing the leaked structure after calling device_unregister().
