sctp: fix incorrect overflow check on autoclose

2012-01-06T22:14:08+00:00

[ Upstream commit 2692ba61a82203404abd7dd2a027bda962861f74 ]

Commit 8ffd3208 voids the previous patches f6778aab and 810c0719 for
limiting the autoclose value.  If userspace passes in -1 on 32-bit
platform, the overflow check didn't work and autoclose would be set
to 0xffffffff.

This patch defines a max_autoclose (in seconds) for limiting the value
and exposes it through sysctl, with the following intentions.

1) Avoid overflowing autoclose * HZ.

2) Keep the default autoclose bound consistent across 32- and 64-bit
   platforms (INT_MAX / HZ in this patch).

3) Keep the autoclose value consistent between setsockopt() and
   getsockopt() calls.

net: refine {udp|tcp|sctp}_mem limits

2011-07-07T07:27:05+00:00

Current tcp/udp/sctp global memory limits are not taking into account
hugepages allocations, and allow 50% of ram to be used by buffers of a
single protocol [ not counting space used by sockets / inodes ...]

Lets use nr_free_buffer_pages() and allow a default of 1/8 of kernel ram
per protocol, and a minimum of 128 pages.
Heavy duty machines sysadmins probably need to tweak limits anyway.

I messed things up when I converted over to the transport

sctp: Don't use rt->rt_{src,dst} in sctp_v4_xmit()

2011-05-08T22:28:29+00:00

Now we can pick it out of the transport's flow key.

inet: Pass flowi to ->queue_xmit().

2011-05-08T22:28:28+00:00

This allows us to acquire the exact route keying information from the
protocol, however that might be managed.

It handles all of the possibilities, from the simplest case of storing
the key in inet->cork.fl to the more complex setup SCTP has where
individual transports determine the flow.

net,rcu: convert call_rcu(sctp_local_addr_free) to kfree_rcu()

2011-05-08T05:50:51+00:00

The rcu callback sctp_local_addr_free() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(sctp_local_addr_free).

sctp: clean up route lookup calls

2011-04-27T20:14:06+00:00

Change the call to take the transport parameter and set the
cached 'dst' appropriately inside the get_dst() function calls.

This will allow us in the future  to clean up source address
storage as well.
