Pull more rdma updates from Doug Ledford:
"This is the second group of code for the 4.7 merge window. It looks
large, but only in one sense. I'll get to that in a minute. The list
of changes here breaks down as follows:- Dynamic counter infrastructure in the IB drivers
This is a sysfs based code to allow free form access to the
hardware counters RDMA devices might support so drivers don't need
to code this up repeatedly themselves- SendOnlyFullMember multicast support
- IB router support
- A couple misc fixes
- The big item on the list: hfi1 driver updates, plus moving the hfi1
driver out of stagingThere was a group of 15 patches in the hfi1 list that I thought I had
in the first pull request but they weren't. So that added to the
length of the hfi1 section here.As far as these go, everything but the hfi1 is pretty straight
forward.The hfi1 is, if you recall, the driver that Al had complaints about
how it used the write/writev interfaces in an overloaded fashion. The
write portion of their interface behaved like the write handler in the
IB stack proper and did bi-directional communications. The writev
interface, on the other hand, only accepts SDMA request structures.
The completions for those structures are sent back via an entirely
different event mechanism.With the security patch, we put security checks on the write
interface, however, we also knew they would be going away soon. Now,
we've converted the write handler in the hfi1 driver to use ioctls
from the IB reserved magic area for its bidirectional communications.
With that change, Intel has addressed all of the items originally on
their TODO when they went into staging (as well as many items added to
the list later).As such, I moved them out, and since they were the last item in the
staging/rdma directory, and I don't have immediate plans to use the
staging area again, I removed the staging/rdma area.Because of the move out of staging, as well as a series of 5 patches
in the hfi1 driver that removed code people thought should be done in
a different way and was optional to begin with (a snoop debug
interface, an eeprom driver for an eeprom connected directory to their
hfi1 chip and not via an i2c bus, and a few other things like that),
the line count, especially the removal count, is high"* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (56 commits)

In practice, each RDMA device has a unique set of counters that the
hardware implements. Having a central set of counters that they must
all adhere to is limiting and causes many useful counters to not be
available.Therefore we create a dynamic counter registration infrastructure.
The driver must implement a stats structure allocation routine, in
which the driver must place the directory name it wants, a list of
names for all of the counters, an array of u64 counters themselves,
plus a few generic configuration options.We then implement a core routine to create a sysfs file for each
of the named stats elements, and a core routine to retrieve the
stats when any of the sysfs attribute files are read.To avoid excessive beating on the stats generation routine in the
drivers, the core code also caches the stats for a short period of
time so that someone attempting to read all of the stats in a
given device's directory will not result in a stats generation
call per file read.Future work will attempt to standardize just the shared stats
elements, and possibly add a method to get the stats via netlink
in addition to sysfs.Signed-off-by: Christoph Lameter

The pio map initialization function is off by 1 causing the last
kernel send context that is allocated to not get mapped into the
pio map which leads to the last kernel send context not being used
by any of the qps.The send context reserved for VL15 is taken care of by setting the
scontext variable that is used as the index into the kernel send
context array to 1 and does not need to be accounted for in the
kernel send context counting loop as it is currently done.Fix the kernel send context counting loop to account for all the
allocated send contexts and map all of them to the different VLs.Reviewed-by: Dennis Dalessandro

When FM is disabled, and the HFI port on the switch is

from the pkey table. This also occurs when the QSFP
cable is moved from a switch port with MgmtAllowed=YES
to a MgmtAllowed=NO port. Clear pkey entry properly.Also, when the driver is loaded and the switch port is
set to MgmtAllowed=NO, FULL_MGMT_P_KEY shouldn't be added

In IB networks, and specifically in IPoIB/rdmacm traffic, the device
address of an IPoIB interface is used as a means to exchange information
between nodes needed for communication.Currently an IPoIB interface will always be created with a device
address based on its node GUID without a way to change that.This change adds the ability to set the device address of an IPoIB
interface by value. We use the set mac address ndo to do that.The flow should be broken down to two:
1) The GID value is already in the GID table,
in this case the interface will be able to set carrier up.2) The GID value is not yet in the GID table,
in this case the interface won't try to join the multicast group
and will wait (listen on GID_CHANGE event) until the GID is inserted.In order to track those changes, we add a new flag:
* IPOIB_FLAG_DEV_ADDR_SET.When set, it means the dev_addr is a based on a value in the gid
table. this bit will be cleared upon a dev_addr change triggered
by the user and set after validation.Per IB spec the port GUID can't change if the module is loaded.
port GUID is the basis for GID at index 0 which is the basis for
the default device address of a ipoib interface.The issue is that there are devices that don't follow the spec,
they change the port GUID while HCA is powered on, so in order
not to break userspace applications. We need to check if the
user wanted to control the device address and we assume that
if he sets the device address back to be based on GID index 0,
he no longer wishs to control it.In order to track this, we add an additional flag:
* IPOIB_FLAG_DEV_ADDR_CTRLWhen setting the device address, there is no validation of the upper
twelve bytes of the device address (flags, qpn, subnet prefix) as those
bytes are not under the control of the user.Signed-off-by: Mark Bloch

There is an assumption that rdmacm is used only between nodes
in the same IB subnet, this why ARP resolution can be used to turn
IP to GID in rdmacm.When dealing with IB communication between subnets this assumption
is no longer valid. ARP resolution will get us the next hop device
address and not the peer node's device address.To solve this issue, we will check user space if it can provide the
GID of the peer node, and fail if not.We add a sequence number to identify each request and fill in the GID
upon answer from userspace.Signed-off-by: Mark Bloch

Previously, mlx5_ib_cq_comp was executed from interrupt context.
Under heavy load, this could cause the CPU core to be in an interrupt
context too long.
Instead of executing the handler from the interrupt context we
execute it from a much friendly tasklet context.Signed-off-by: Matan Barak

In the Ethernet/TCP world, CAP_NET_RAW is sufficient to allow a program
to listen to all incoming packets on a specific interface, and the
higher CAP_NET_ADMIN is required to set the interface into promiscuous
mode. We want to emulate that same basic division of privilege in the
RDMA stack, so when dealing with Raw Ethernet QPs, allow apps with
CAP_NET_RAW to listen to all incoming flows (and direct them as they see
fit in their own listen stream). Do not require CAP_NET_ADMIN just to
listen to traffic already incoming. Reserve CAP_NET_ADMIN if we attempt
to set promiscuous mode.Signed-off-by: Christoph Lameter

The problem is that the function 'send_reply_to_slave' gets the
'req_sa_mad' as a pointer whose address is only aliged to 4 bytes
but is 8 bytes in size. This can result in unaligned access faults
on certain architectures.Sowmini Varadhan pointed to this reply from Dave Miller that say
that memcpy should not be used to solve alignment issues:
https://lkml.org/lkml/2015/10/21/352Optimization of memcpy to 'ldx' instruction can only happen if the
compiler knows that the size of the data we are copying is 8 bytes
and it assumes it is aligned to 8 bytes. If the compiler know the
type is not aligned to 8 it must not optimize the 8 byte copy.
Defining the data type as aligned to 4 forces the compiler to treat
all accesses as though they aren't aligned and avoids the 'ldx'
optimization.Full credit for the idea goes to Jason Gunthorpe

Instead of special casing the handful of callers that check for
iser-target rdma verbs specific shutdown, use a simple flag at
iscsit_transport->rdma_shutdown so each driver can signal this.Also, update iscsi-target/tcp + cxgbit to rdma_shutdown = false.

Since all the uverbs device_cap_flags are occupied, we need a place to
expose more device capabilities.This patch adds a new 64 bit device_cap_flags_ex to expose new
device capabilities.The lower 32 bits will be identical to the original device_cap_flags,
The upper 32 bits will be new capabilities.Signed-off-by: Majd Dibbiny
