net: Remove unnecessary returns from void function()s

2010-05-18T06:23:14+00:00

This patch removes from net/ (but not any netfilter files)
all the unnecessary return; statements that precede the
last closing brace of void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

sctp: Optimize computation of highest new tsn in SACK.

2010-05-01T02:41:10+00:00

Right now, if the highest tsn in the SACK doesn't change, we'll
end up scanning the transmitted lists on the transports twice:
once for locating the highest _new_ tsn, and once for actually
tagging chunks as acked.  This is a waste, since we can record
the highest _new_ tsn at the same time as tagging chunks.  Long
ago this was not possible because we would try to mark chunks
as missing at the same time as tagging them acked and this approach
didn't work.  Now that the two steps are separate, we can re-use
the old approach.

sctp: correctly mark missing chunks in fast recovery

2010-05-01T02:41:10+00:00

According to RFC 4960 Section 7.2.4:
 					If an endpoint is in Fast
   Recovery and a SACK arrives that advances the Cumulative TSN Ack
   Point, the miss indications are incremented for all TSNs reported
   missing in the SACK.

sctp: Do not force T3 timer on fast retransmissions.

2010-05-01T02:41:09+00:00

We don't need to force the T3 timer any more and it's
actually wrong to do as it causes too long of a delay.
The timer will be started if one is not running, but if
one is running, we leave it alone.

sctp: remove 'resent' bit from the chunk

2010-05-01T02:41:09+00:00

The 'resent' bit is used to make sure that we don't update
rto estimate based on retransmitted chunks.  However, we already
have the 'rto_pending' bit that we test when need to update rto,
so 'resent' bit is just extra.  Additionally, we currently have
a bug in that we always set a 'resent' bit and thus rto estimate
is only updated by Heartbeats.

sctp: use sctp_chunk_is_data macro to decide a chunk is data chunk

2010-05-01T02:41:09+00:00

sctp_chunk_is_data macro is defined to decide that
whether a chunk is data chunk or not.

sctp: fix to retranmit at least one DATA chunk

2010-05-01T02:38:53+00:00

While doing retranmit, if control chunk exists, such as
FORWARD TSN chunk, and the DATA chunk can not be bundled with
this control chunk because of PMTU limit, no DATA chunk
will be retranmitted in the current implementation. This
patch makes sure to retranmit at least one DATA chunk in this case.
