sctp: Add validity check for SCTP_PARTIAL_DELIVERY_POINT socket option

2008-12-26T00:59:03+00:00

The latest ietf socket extensions API draft said:

  8.1.21.  Set or Get the SCTP Partial Delivery Point

    Note also that the call will fail if the user attempts to set
    this value larger than the socket receive buffer size.

This patch add this validity check for SCTP_PARTIAL_DELIVERY_POINT
socket option.

sctp: Implement socket option SCTP_GET_ASSOC_NUMBER

2008-12-26T00:57:24+00:00

Implement socket option SCTP_GET_ASSOC_NUMBER of the latest ietf socket
extensions API draft.

  8.2.5.  Get the Current Number of Associations (SCTP_GET_ASSOC_NUMBER)

   This option gets the current number of associations that are attached
   to a one-to-many style socket.  The option value is an uint32_t.

net: Use a percpu_counter for sockets_allocated

2008-11-26T05:16:35+00:00

Instead of using one atomic_t per protocol, use a percpu_counter
for "sockets_allocated", to reduce cache line contention on
heavy duty network servers. 

Note : We revert commit (248969ae31e1b3276fc4399d67ce29a5d81e6fd9
net: af_unix can make unix_nr_socks visbile in /proc),
since it is not anymore used after sock_prot_inuse_add() addition

net: Make sure BHs are disabled in sock_prot_inuse_add()

2008-11-25T21:53:27+00:00

prot->destroy is not called with BH disabled. So we must add
explicit BH disable around call to sock_prot_inuse_add()
in sctp_destroy_sock()

net: Make sure BHs are disabled in sock_prot_inuse_add()

2008-11-24T01:34:03+00:00

The rule of calling sock_prot_inuse_add() is that BHs must
be disabled.  Some new calls were added where this was not
true and this tiggers warnings as reported by Ilpo.

Fix this by adding explicit BH disabling around those call sites.

net: sctp should update its inuse counter

2008-11-17T10:41:00+00:00

This patch is a preparation to namespace conversion of /proc/net/protocols

In order to have relevant information for SCTP protocols, we should use
sock_prot_inuse_add() to update a (percpu and pernamespace) counter of
inuse sockets.

sctp: try harder to figure out address family when checking wildcards

2008-10-01T15:33:06+00:00

sctp_is_any() function that is used to check for wildcard addresses
only looks at the address itself to determine the address family.
This function is used in the API to check the address passed in from
the user.  If the user simply zerroes out the sockaddr_storage and
pass that in, we'll end up failing.  So, let's try harder to determine
the address family by also checking the socket if it's possible.
