[TIPC]: Optimize stream send routine to avoid fragmentation

2007-07-11T05:06:12+00:00

This patch enhances TIPC's stream socket send routine so that
it avoids transmitting data in chunks that require fragmentation
and reassembly, thereby improving performance at both the
sending and receiving ends of the connection.

The "maximum packet size" hint that records MTU info allows
the socket to decide how big a chunk it should send; in the
event that the hint has become stale, fragmentation may still
occur, but the data will be passed correctly and the hint will
be updated in time for the following send.  Note: The 66060 byte
pseudo-MTU used for intra-node connections requires the send
routine to perform an additional check to ensure it does not
exceed TIPC"s limit of 66000 bytes of user data per chunk.

[TIPC]: Use standard socket "not implemented" routines

2007-07-11T05:06:09+00:00

This patch modifies TIPC's socket API to utilize existing
generic routines to indicate unsupported operations, rather
than adding similar TIPC-specific routines.

[SK_BUFF]: Convert skb->tail to sk_buff_data_t

2007-04-26T05:26:28+00:00

So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

[TIPC]: Optimize wakeup logic when socket has no waiting processes

2006-10-19T02:55:17+00:00

This patch adds a simple test so TIPC doesn't try waking up processes
waiting on a socket if there are none waiting.

[TIPC]: Stream socket can now send > 66000 bytes at a time

2006-10-19T02:55:15+00:00

The stream socket send code was not initializing some required fields
of the temporary msghdr structure it was utilizing; this is now fixed.
A check has also been added to detect if a user illegally specifies
a destination address when sending on an established stream connection.
