Add callbacks and data types for statistics export of all current
devices/ids. The schema for RDMA CM is a series of netlink messages.
Each one contains an rdma_cm_stat struct. Additionally, two netlink
attributes are created for the addresses for each message (if
applicable).
Their types used are:
RDMA_NL_RDMA_CM_ATTR_SRC_ADDR (The source address for this ID)
RDMA_NL_RDMA_CM_ATTR_DST_ADDR (The destination address for this ID)
sockaddr_* structs are encapsulated within these attributes.
In other words, every transaction contains a series of messages like:
-------message 1-------
struct rdma_cm_id_stats {
__u32 qp_num;
__u32 bound_dev_if;
__u32 port_space;
__s32 pid;
__u8 cm_state;
__u8 node_type;
__u8 port_num;
__u8 reserved;
}
RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute - contains the source address
RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute - contains the destination address
-------end 1-------
-------message 2-------
struct rdma_cm_id_stats
RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute
RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute
-------end 2-------

The RDMA CM currently infers the QP type from the port space selected
by the user. In the future (eg with RDMA_PS_IB or XRC), there may not
be a 1-1 correspondence between port space and QP type. For netlink
export of RDMA CM state, we want to export the QP type to userspace,
so it is cleaner to explicitly associate a QP type to an ID.
Modify rdma_create_id() to allow the user to specify the QP type, and
use it to make our selections of datagram versus connected mode.

tx_ack() wasn't checking the endpoint state and consequently would
attempt to post the p2p 0B read on an endpoint/QP that is closing or
aborting. This causes a NULL pointer dereference crash.
Signed-off-by: Steve Wise <swise@opengridcomputing.com>
Signed-off-by: Roland Dreier <roland@purestorage.com>
There exists a race condition when using wait_queue_head_t objects
that are declared on the stack. This was being done in a few places
where we are sending work requests to the FW and awaiting replies, but
we don't have an endpoint structure with an embedded c4iw_wr_wait
struct. So the code was allocating it locally on the stack. Bad
design. The race is:
1) thread on cpuX declares the wait_queue_head_t on the stack, then
posts a firmware WR with that wait object ptr as the cookie to be
returned in the WR reply. This thread will proceed to block in
wait_event_timeout() but before it does:
2) An interrupt runs on cpuY with the WR reply. fw6_msg() handles
this and calls c4iw_wake_up(). c4iw_wake_up() sets the condition
variable in the c4iw_wr_wait object to TRUE and will call
wake_up(), but before it calls wake_up():
3) The thread on cpuX calls c4iw_wait_for_reply(), which calls
wait_event_timeout(). The wait_event_timeout() macro checks the
condition variable and returns immediately since it is TRUE. So
this thread never blocks/sleeps. The function then returns
effectively deallocating the c4iw_wr_wait object that was on the
stack.
4) So at this point cpuY has a pointer to the c4iw_wr_wait object
that is no longer valid. Further its pointing to a stack frame
that might now be in use by some other context/thread. So cpuY
continues execution and calls wake_up() on a ptr to a wait object
that as been effectively deallocated.
This race, when it hits, can cause a crash in wake_up(), which I've
seen under heavy stress. It can also corrupt the referenced stack
which can cause any number of failures.
The fix:
Use struct completion, which supports on-stack declarations.
Completions use a spinlock around setting the condition to true and
the wake up so that steps 2 and 4 above are atomic and step 3 can
never happen in-between.

There is no point in counting hits - we can calculate it from the number

This makes the avc statistics a bit smaller, and makes the code
generation better too.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
You can turn off the avc cache stats, but distributions seem to not do
that (perhaps because several performance tuning how-to's talk about the
avc cache statistics).
Which is sad, because the code it generates is truly horrendous, with
the statistics update being sandwitched between get_cpu/put_cpu which in
turn causes preemption disables etc. We're talking ten+ instructions
just to increment a per-cpu variable in some pretty hot code.
Fix the craziness by just using 'this_cpu_inc()' instead. Suddenly we
only need a single 'inc' instruction to increment the statistics. This
is quite noticeable in the incredibly hot avc_has_perm_noaudit()
function (which triggers all the statistics by virtue of doing an
avc_lookup() call).
