rsocket: Segmentation fault fix in case of multiple connections
In case of more than 16 rsocket connections
are established, "svc->rss" buffer is reallocated
with more memory. Index 0 is reserved for the service's
communication socket, and this is not taken in count
when data is copied from old buffer location to
new one.

riostream: Only verify last data transfer
Data verification will fail when running the bandwidth
tests or the transfer count is > 1. The issue is that
subsequent writes by the initiator side will overwrite
the data in the target buffer before the receiver can
verify that it is correct.
To fix this, only verify that the data in the buffer
is correct after the last transfer has completed.

rsocket: Update correct rsocket keepalive time
When the keepalive time of an rsocket is updated, the
updated information is forwarded to the keepalive service
thread. However, the thread updates the time for the
wrong service as shown:
tcp_svc_timeouts[svc->cnt] = rs_get_time() + msg.rs->keepalive_time;
The index into tcp_svc_timeouts should correspond to the
rsocket being updated, not the last one in the list.

rsocket: Fix removing rsocket from service thread
When removing an rsocket from a service thread, we replace
the removed service with the one at the end of the service list.
This keeps the array tightly packed. However, rs_svc_rm_rs
decrements the rsocket count before doing the swap. The result
is that the entry at the end of the list gets dropped off.
Defer decrementing the count until the swap has been made.
In this case, the cnt value is a valid index into the array,
because we start at index 1. Index 0 is used internally by
the service thread.

rsocket: Fix crash resulting from keepalive timeout
The following crash was reported by Hal Rosenstock,
<hal@mellanox.com>, with keepalive enabled. The crash
occurs in the keepalive thread attempting to send a
keepalive message.
report:
Program received signal SIGSEGV, Segmentation fault.

1667 }

So qp is NULL somehow...
:end report
There is an issue if an rsocket is closed without going through
the rshutdown.
int rshutdown(int socket, int how)
{
...
if (rs->opts & RS_OPT_SVC_ACTIVE)
rs_notify_svc(&tcp_svc, rs, RS_SVC_REM_KEEPALIVE);
We remove the rsocket from the keepalive thread in rshutdown.
int rclose(int socket)
{
...
if (rs->state & rs_connected)
rshutdown(socket, SHUT_RDWR);
...
rs_free(rs);
rclose will call shutdown only if we're connected. However, if the
keepalive failed, the socket will be in an error state. So,
no call to rshutdown, which will leave the freed rsocket on
the keepalive thread's list.
The fix is to to have rclose remove an rsocket from being processed
by a service thread if it is still active.

rdma_server: handle IBV_SEND_INLINE correctly
Not all RDMA devices support IBV_SEND_INLINE. At least some of those
that don't will ignore the flag passed to rdma_post_send and attempt to
send the command by using an sge entry instead. Because we don't
register the send memory, this fails. The proper way to deal with the
fact that IBV_SEND_INLINE is not guaranteed is to check the returned
value in our cap struct to see if we have support for inline data, and
if not, fall back to non-inline sends and to register the send memory
region.

cmtime: rework program to be multithread
When using very large numbers of connections (10,000 was in use here),
we ran into a problem where when we resolved a performance problem in
the kernel cma.c code, we suddenly developed a new problem. That new
problem turned out to be the fact that with the underlying kernel issue
resolved, 10,000 connect requests would flood the server side of the
test and the cmtime application would respond as quickly as possible.
However, the client side would not bother to check any of the returns
until after having sent all 10,000 connect requests. When the kernel
had a serializing performance problem, this was OK. When it was fixed,
this caused a general slowdown in connect operations due to overruns in
the event processing. This patch causes the client side to fire off
threads that will handle responses to connect requests as they come in
instead of allowing them to backlog uncontrollably. Times for a 10,000
connect run changed from this:

rsocket: Relax requirement for minimal inline data
Inline data support is optional. Allow rsockets to work
with devices that do not support inline data, provided
that they do support RDMA writes with immediate data.
This allows rsockets to work over Intel TrueScale HCA.

rsocket: Modify when control messages are available
Rsockets currently tracks how many control messages (i.e.
entries in the send queue) that are available using a
single ctrl_avail counter. Seems simple enough.
However, control messages currently require the use of
inline data. In order to support control messages that
do not use inline data, we need to associate each
control message with a specific data buffer. This will
become easier to manage if we modify how we track when
control messages are available.
We replace the single ctrl_avail counter with two new
counters. The new counters conceptually treat control
messages as if each message had its own sequence number.
The sequence number will then be able to correspond to
a specific data buffer in a follow up patch.
ctrl_seqno will be used to indicate the current control
message being sent. ctrl_max_seqno will track the
highest control message that may be sent.
A side effect of this change is that we will be able to
see how many control messages have been sent. This also
separates the updating of the control count on the
sending side, versus the receiving side.

rsocket: Dedicate a fixed number of SQEs for control messages
The number of SQEs allocated for control messages is set
to 1 of 2 constant values (either 4 or 2). A default
value is used unless the size of the SQ is below a certain
threshold (16 entries). This results in additional code
complexity, and it is highly unlikely that the SQ would
ever be allocated smaller than 16 entries.
Simplify the code to use a single constant value for the
number of SQEs allocated for control messages. This will
also help in subsequent patches that will need to deal
with HCAs that do not support inline data.

librdmacm: Support lazy initialization
librdmacm currently opens a device context per configured HCA. This is
usually done in rdma_create_event_channel() or first time whenever
ucma_init() is called. If a process is only going to use one of the
configured HCAs/RDMA IPs then the remaining device contexts are not
used/required. Opening a device context on each device apriori limits the
maximum number of processes that can be supported on a node to the maximum
number of open context supported per HCA regardless of number of HCAs present
in the system.

rsocket: Fix sbuf_bytes_avail counter 'overrun' with iwarp
Reported-by: Jonas Pfefferle1 <JPF@zurich.ibm.com>
"The problem is that on the client side sbuf_bytes_avail overflows
in rs_poll_cq. And from what I debugged so far there are 2
completions for every send and this is because I use iWarp hardware
which does not support write with immediate so there is one completion
for the write and one for the send (both go into the default case
and add the length to sbuf_bytes_avail)."
To avoid the issue, we flag send message operations that are used
in place of immediate data. Other send message operations are
not affected. The completion code can then check whether the
completion is for a send message which was paired with an RDMA
write transaction and adjust the behavior accordingly. Additionally,
such send messages only carry the opcode in their WR_ID, with the
data portion zeroed. This avoids adding the length value twice.

udaddy: Remove support for port space IB
UD support for the IB port space requires that the application
use rdma_create_ep, rather than rdma_create_id. However, using
rdma_create_ep results in address and route resolution being
performed synchronously as part of the rdma_create_ep call.
Since udaddy is an example, we want to show how it can be used
with asynchronous events. So, rather than update udaddy to
use rdma_create_ep in order to support the IB port space, it
would be better to remove that support.

rsockets: Handle race between rshutdown and rpoll
Multi-threaded applications which call rpoll and rshutdown
simultaneously can hang. Ceph developers reported an issue
with the rsocket implementation. Ceph calls rpoll in
one thread, and while that thread is blocked in rpoll,
a second thread may cann rshutdown on the socket. In
normal sockets, this results in the poll call unblocking
(since a call to read on the socket will no longer block).
however, rsockets does not free the thread blocked on the
rpoll call.
To fix this, we add some additional state checking to
protect against threads calling rpoll and rshutdown
simultaneously. We also have the rshutdown call
transition the QP into an error state. This causes all
posted receives to complete as flushed, which results
in unblocking the thread in rpoll (to process the flushed
receives).

acm: Define needed ACM protocol messages
The librdmacm needs message definitions used to communicate
with the ibacm. It currently pulls these from infiniband/acm.h,
which is installed by ibacm. This creates an install order
dependency on ibacm. However, work on the scalable SA has
the ibacm using the librdmacm (via rsockets) for communication
between the different SSA components.
To resolve this issue, have the librdmacm define the message
structures that it needs to communicate with ibacm. The
librdmacm already defines some ACM messages through configuration
checks. We just expand that capability, which isolates the librdmacm
package from the ibacm package.

Open files with "close on exec" flag
File opened by librdmacm are not supposed to be inherited across
exec*(), most of the files are of no use for another program, and
others cannot be used without the associated memory mapping.
This patch changes fopen() open() and socket() to always set
close on exec flag.
This patch also add checks to configure to guess if fopen() supports
"e" flag. If O_CLOEXEC and SOCK_CLOEXEC are supported, fopen() should
support "e". If not supported, its discarded according to POSIX. Many
operating systems have support for fopen("e").

configure: Use automake's option "subdir-objects"
Following advice in "Autotool Mythbuster" [1], option subdir-objects
can be used to have Makefiles create object files in the same
directory than theirs source files.
It reduces clobbering in the build directory.

librdmacm/rsocket: Fix resetting O_NONBLOCK after calling shutdown
Shutdown switches an rsocket from nonblocking to blocking to
ensure that all data has been sent. After completing all
transfers, it should switch back to nonblocking; this handles
partial shutdown situations, where only half the connection
is shut down. However, the code uses the value of '1' to
set the nonblocking flag, rather than O_NONBLOCK. Fix this.

librdmacm: Work-around kernel bug returning uid = 0
Older kernels have a bug where it can report an event with the
uid set to 0. The librdmacm crashes when casting the uid to
an rdma_cm_id and dereferencing the NULL pointer.
There are a limited number of events where this can occur and
in most cases it's safe to simply discard the event. (This is
what the kernel does anyway.) However, it's possible for us
to process an RDMA_CM_EVENT_ESTABLISHED event with the uid
set to 0. (See kernel commit 418edaaba96e58112b15c82b4907084e2a9caf42.)
Although it's rare for this to occur, it does in fact happen
in practice. To work-around the kernel bug, when the uid of an
established event is set to 0, we first try to locate the correct
user space id based on related data before discarding the event.

rsockets: Add support for existing UDP apps
Support for existing UDP applications is done via the rspreload
library. However, when the preload library is loaded, socket
calls used by rsockets get intercepted and converted into
rsocket calls.
The preload library was able to handle this for TCP rsockets
by using a per thread variable and checking for recursive calls
coming from rsockets back into the preload library. The preload
library would direct such calls to the real socket calls.
The problem is more complex for UDP rsockets, which can invoke
socket calls from an internal rsocket thread. The result is that
the preload library intercepts socket calls that originate from
the rsocket library which are not recursive.
Although, this is really a problem with the preload library,
the simplest solution is for rsockets to fully initialize the
library when allocating the first rsocket, versus deferring
initialization until required. The preload library can then
detect the recursive calls.

rsocket: Add datagram support
Add datagram support through the rsocket API.
Datagram support is handled through an entirely different protocol and
internal implementation than streaming sockets. Unlike connected rsockets,
datagram rsockets are not necessarily bound to a network (IP) address.
A datagram socket may use any number of network (IP) addresses, including
those which map to different RDMA devices. As a result, a single datagram
rsocket must support using multiple RDMA devices and ports, and a datagram
rsocket references a single UDP socket, plus zero or more UD QPs.
Rsockets uses headers inserted before user data sent over UDP sockets to
resolve remote UD QP numbers. When a user first attempts to send a datagram
to a remote address (IP and UDP port), rsockets will take the following steps:
1. Store the destination address into a lookup table.
2. Resolve which local network address should be used when sending
to the specified destination.
3. Allocate a UD QP on the RDMA device associated with the local address.
4. Send the user's datagram to the remote UDP socket.
A header is inserted before the user's datagram. The header specifies the
UD QP number associated with the local network address (IP and UDP port) of
the send.
A service thread is used to process messages received on the UDP socket. This
thread updates the rsocket lookup tables with the remote QPN and path record
data. The service thread forwards data received on the UDP socket to an
rsocket QP. After the remote QPN and path records have been resolved, datagram
communication between two nodes are done over the UD QP.

rsocket: Add APIs for direct data placement
We introduce rsocket extensions for supporting direct
data placement (also known as zero copy). Direct data
placement avoids data copies into network buffers when
sending or receiving data. This patch implements zero
copies on the receive side, but adds some basic framework for
supporting it on the sending side.
Integrating zero copy support into the existing socket APIs
is difficult to achieve when the sockets are set as
nonblocking. Any such implementation is likely to be unusable
in practice. The problem stems from the fact that socket
operations are synchronous in nature. Support for asynchronous
operations is limited to connection establishment.
Therefore we introduce new calls to handle direct data placement.
The use of the new calls is optional and does not affect the
use of the existing calls. An attempt is made to have the new
routines integrate naturally with the existing APIs. The new
functions are: riomap, riounmap, and riowrite. The basic operation
can be described as follows:
1. App A calls riomap to register a data buffer with the local
RDMA device. Riomap returns an off_t offset value that
corresponds to the registered data buffer. The app may
select the offset value.
2. Rsockets will transmit an internal message to the remote
peer with information about the registration. This exchange
is hidden from the applications.
3. App A sends a notification message to app B indicating that
the remote iomapped buffer is now available to receive data.
4. App B calls riowrite to transmit data directly into the
riomapped data buffer.
5. App B sends a notification message to app A indicating that
data is available in the mapped buffer.
6. After all transfers are complete, app A calls riounmap to
deregister its data buffer.
Riomap and riounmap are functionally equivalent to RDMA
memory registration and deregistration routines. They are loosely
based on the mmap and munmap APIs.
off_t riomap(int socket, void *buf, size_t len,
int prot, int flags, off_t offset)
Riomap registers an application buffer with the RDMA hardware
associated with an rsocket. The buffer is registered either for
local only access (PROT_NONE) or for remote write access (PROT_WRITE).
When registered for remote access, the buffer is mapped to a given
offset. The offset is either provided by the user, or if the user
selects -1 for the offset, rsockets selects one. The remote peer may
access an iomapped buffer directly by specifying the correct offset.
The mapping is not guaranteed to be available until after the remote
peer receives a data transfer initiated after riomap has completed.
int riounmap(int socket, void *buf, size_t len)
Riounmap removes the mapping between a buffer and an rsocket.
size_t riowrite(int socket, const void *buf, size_t count,
off_t offset, int flags)
Riowrite allows an application to transfer data over an rsocket
directly into a remotely iomapped buffer. The remote buffer is specified
through an offset parameter, which corresponds to a remote iomapped buffer.
From the sender's perspective, riowrite behaves similar to rwrite. From
a receiver's view, riowrite transfers are silently redirected into a pre-
determined data buffer. Data is received automatically, and the receiver
is not informed of the transfer. However, iowrite data is still considered
part of the data stream, such that iowrite data will be written before a
subsequent transfer is received. A message sent immediately after
initiating an iowrite may be used to notify the receiver of the iowrite.
It should be noted that the current implementation primarily focused
on being functional for evaluation purposes. Some checks have been
deferred for subsequent patches, and performance is currently limited
by linear lookups.

rdma_xserver/client: Fix man page formatting
Putting 'r' at the beginning of a line in the nroff source for man pages
is confusing to nroff because lines that start with a single quote
character ' or a dot character . are treated as control lines, which is
not what's intended here. Some of the man page text ends up left out of
the formatted output.
Fix this by just wrapping the text slightly differently in the source
(which doesn't matter since nroff reflows the text anyway). Also add a
missing ".TP" so that the -p and -c options are not run together in the
formatted output.
