Allan Stephens c29c3f70c9 tipc: Abort excessive send requests as early as possible
Adds checks to TIPC's socket send routines to promptly detect and
abort attempts to send more than 66,000 bytes in a single TIPC
message or more than 2**31-1 bytes in a single TIPC byte stream request.
In addition, this ensures that the number of iovecs in a send request
does not exceed the limits of a standard integer variable.

Allan Stephens 77c81e0bb8 tipc: Clean out all remaining instances of #if 0'd unused code
Remove all instances of legacy or proposed-but-not-implemented code
that lives within an #if 0 ... #endif block.  If some of it is needed
in the future it can recovered out of history, but there is no need
for it to clutter up the active code base.

Allan Stephens 0e65967e33 tipc: cleanup various cosmetic whitespace issues
Cleans up TIPC's source code to eliminate deviations from generally
accepted coding conventions relating to leading/trailing white space
and white space around commas, braces, cases, and sizeof.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

Neil Horman 8c97443808 Revert c6537d6742
Backout the tipc changes to the flags int he subscription message.  These
changees, while reasonable on the surface, interefere with user space ABI
compatibility which is a no-no.  This was part of the changes to fix the
endianess issues in the TIPC protocol, which would be really nice to do but we
need to do so in a way that is backwards compatible with user space.

Jon Paul Maloy c6537d6742 TIPC: Updated topology subscription protocol according to latest spec
This patch makes it explicit in the API that all fields in subscriptions and events exchanged with the Topology Server must be in
network byte order.
It also ensures that all fields of a subscription are compared when cancelling a subscription, in order to avoid inadvertent
cancelling of the wrong subscription.
Finally, the tipc module version is updated to 2.0.0, to reflect the API change.

oscar.medina@motorola.com 6650613d33 tipc: Add socket options to get number of queued messages
This patch allows a TIPC application to determine the number of messages
currently waiting in a socket's receive queue (TIPC_SOCK_RECVQ_DEPTH) or
in all TIPC socket receive queues (TIPC_NODE_RECVQ_DEPTH).

Lijun Chen eb409460b1 [TIPC]: Added subscription cancellation capability
This patch allows a TIPC application to cancel an existing
topology service subscription by re-requesting the subscription
with the TIPC_SUB_CANCEL filter bit set.  (All other bits of
the cancel request must match the original subscription request.)
