SCTP: Always linearise packet on input

2006-11-29T11:06:04+00:00

I was looking at a RHEL5 bug report involving Xen and SCTP
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=212550).
It turns out that SCTP wasn't written to handle skb fragments at
all.  The absence of any calls to skb_may_pull is testament to
that.

It just so happens that Xen creates fragmented packets more often
than other scenarios (header & data split when going from domU to
dom0).  That's what caused this bug to show up.

Until someone has the time sits down and audits the entire net/sctp
directory, here is a conservative and safe solution that simply
linearises all packets on input.

[SCTP]: Fix couple of races between sctp_peeloff() and sctp_rcv().

2006-01-17T19:56:26+00:00

Validate and update the sk in sctp_rcv() to avoid the race where an
assoc/ep could move to a different socket after we get the sk, but before
the skb is added to the backlog.

Also migrate the skb's in backlog queue to new sk when doing a peeloff.

[SCTP]: Fix potential race condition between sctp_close() and sctp_rcv().

2006-01-17T19:51:28+00:00

Do not release the reference to association/endpoint if an incoming skb is
added to backlog. Instead release it after the chunk is processed in
sctp_backlog_rcv().

[NETFILTER]: Keep conntrack reference until IPsec policy checks are done

2006-01-07T20:57:36+00:00

Keep the conntrack reference until policy checks have been performed for
IPsec NAT support. The reference needs to be dropped before a packet is
queued to avoid having the conntrack module unloadable.

[SCTP]: Update SCTP_PEER_ADDR_PARAMS socket option to the latest api draft.

2006-01-03T21:11:11+00:00

This patch adds support to set/get heartbeat interval, maximum number of
retransmissions, pathmtu, sackdelay time for a particular transport/
association/socket as per the latest SCTP sockets api draft11.

[SCTP]: Include ulpevents in socket receive buffer accounting.

2005-11-12T00:08:24+00:00

Also introduces a sysctl option to configure the receive buffer
accounting policy to be either at socket or association level.
Default is all the associations on the same socket share the
receive buffer.
