[TIPC]: Fix semaphore handling.

2007-12-14T21:54:37+00:00

As noted by Kevin, tipc's release() does down_interruptible() and
ignores the return value.  So if signal_pending() we'll end up doing
up() on a non-downed semaphore.  Fix.

[NET]: Forget the zero_it argument of sk_alloc()

2007-11-01T07:39:31+00:00

Finally, the zero_it argument can be completely removed from
the callers and from the function prototype.

Besides, fix the checkpatch.pl warnings about using the
assignments inside if-s.

This patch is rather big, and it is a part of the previous one.
I splitted it wishing to make the patches more readable. Hope 
this particular split helped.

[NET]: Make socket creation namespace safe.

2007-10-10T23:49:07+00:00

This patch passes in the namespace a new socket should be created in
and has the socket code do the appropriate reference counting.  By
virtue of this all socket create methods are touched.  In addition
the socket create methods are modified so that they will fail if
you attempt to create a socket in a non-default network namespace.

Failing if we attempt to create a socket outside of the default
network namespace ensures that as we incrementally make the network stack
network namespace aware we will not export functionality that someone
has not audited and made certain is network namespace safe.
Allowing us to partially enable network namespaces before all of the
exotic protocols are supported.

Any protocol layers I have missed will fail to compile because I now
pass an extra parameter into the socket creation code.

[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.
