Rework TIPC's message sending routines to take advantage of the total
amount of data value passed to it by the kernel socket infrastructure.
This change eliminates the need for TIPC to compute the size of outgoing
messages itself, as well as the check for an oversize message in
tipc_msg_build(). In addition, this change warrants an explanation:- res = send_packet(NULL, sock, &my_msg, 0);
+ res = send_packet(NULL, sock, &my_msg, bytes_to_send);Previously, the final argument to send_packet() was ignored (since the
amount of data being sent was recalculated by a lower-level routine)
and we could just pass in a dummy value (0). Now that the
recalculation is being eliminated, the argument value being passed to
send_packet() is significant and we have to supply the actual amount
of data we want to send.Signed-off-by: Allan Stephens

Merge two distinct structures containing information about a TIPC port
into a single structure. The structures were previously kept separate
so that public information about a port could be made available to
applications using TIPC's native API, while the remaining information
was kept private for use by TIPC itself. However, now that the native
API has been removed there is no longer any need for this somewhat
confusing arrangement.Since one of the structures was already embedded within the other, the
change largely involves replacing instances of "publ.foo" with "foo".
The changes do not otherwise alter the operation of TIPC ports.Signed-off-by: Allan Stephens

As part of the removal of TIPC's native API support it is no longer
necessary for TIPC to export symbols for routines that can be called
by kernel-based applications, nor for it to have header files that
kernel-based applications can include to access the declarations for
those routines. This commit eliminates the exporting of symbols by
TIPC and migrates the contents of each obsolete native API include
file into its corresponding non-native API equivalent.The code which was migrated in this commit was migrated intact, in
that there are no technical changes combined with the relocation.Signed-off-by: Allan Stephens

TIPC needs to have its endianess issues fixed. Unfortunately, the format of a
subscriber message is passed in directly from user space, so requiring this
message to be in network byte order breaks user space ABI. Revert this change

manner.Signed-off-by: Neil Horman

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.Signed-off-by: Jon Maloy

Remove htohl implementation from tipc
I was working on forward porting the downstream commits for TIPC and ran accross this one:
http://tipc.cslab.ericsson.net/cgi-bin/gitweb.cgi?p=people/allan/tipc.git;a=commitdiff;h=894279b9437b63cbb02405ad5b8e033b51e4e31eI was going to just take it, when I looked closer and noted what it was doing.
This is basically a routine to byte swap fields of data in sent/received packets
for tipc, dependent upon the receivers guessed endianness of the peer when a
connection is established. Asside from just seeming silly to me, it appears to
violate the latest RFC draft for tipc:
http://tipc.sourceforge.net/doc/draft-spec-tipc-02.txt
Which, according to section 4.2 and 4.3.3, requires that all fields of all
commands be sent in network byte order. So instead of just taking this patch,
instead I'm removing the htohl function and replacing the calls with calls to
ntohl in the rx path and htonl in the send path.As part of this fix, I'm also changing the subscr_cancel function, which
searches the list of subscribers, using a memcmp of the entire subscriber list,
for the entry to tear down. unfortunately it memcmps the entire tipc_subscr
structure which has several bits that are private to the local side, so nothing
will ever match. section 5.2 of the draft spec indicates the
tuple should uniquely identify a subscriber, so convert subscr_cancel to just
match on those fields (properly endian swapped).I've tested this using the tipc test suite, and its passed without issue.

This patch modifies TIPC's network topology service so that it
only requires a single reference table entry per subscriber
connection, rather than two. This is achieved by letting the
reference to the server port communicating with the subscriber
act as the reference to the subscriber object itself. (Since
the subscriber cannot exist without its port, and vice versa,
this dual role for the reference is perfectly natural.) This
consolidation reduces the size of the reference table by 50%
in the default configuration.Signed-off-by: Allan Stephens

This patch fixes TIPC's topology server so that it does byte swapping
correctly when endianness conversion is required. (Note: This bug only
impacted an application if it issues a subscription request to a
topology server on another node, rather than the server on it's own
node; since the topology server is normally not accessible by off-node
applications, most TIPC applications were not impacted by the bug.)Signed-off-by: Allan Stephens

With reference to latest discussions on linux-kernel with respect to
inline here is a patch for tipc to remove all inlines as used in
the .c files. See also chapter 14 in Documentation/CodingStyle.Before:
text data bss dec hex filename
102990 5292 1752 110034 1add2 tipc.oNow:
text data bss dec hex filename
101190 5292 1752 108234 1a6ca tipc.oThis is a nice text size reduction which will improve icache usage.
In some cases bigger (> 4 lines) functions where declared inline
and used in many places, they are most probarly no longer inlined by gcc
resulting in the size reduction.
There are several one liners that no longer are declared inline, but gcc
should inline these just fine without the inline hint.With this patch applied one warning is added about an unused static
function - that was hidded by utilising inline before.
The function in question were kept so this patch is solely a
inline removal patch.Signed-off-by: Sam Ravnborg
