sctp: fix missing send up SCTP_SENDER_DRY_EVENT when subscribe it

2011-07-07T11:10:26+00:00

We forgot to send up SCTP_SENDER_DRY_EVENT notification when
user app subscribes to this event, and there is no data to be
sent or retransmit.

This is required by the Socket API and used by the DTLS/SCTP
implementation.

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.

net: vlan: enable soft features regardless of underlying device

2011-07-06T03:43:12+00:00

If gso/gro feature of underlying device is turned off，
then new created vlan device never can turn gso/gro on. 

Although underlying device don't support TSO, we still
should use software segments for vlan device.

bridge: Always flood broadcast packets

2011-07-06T01:39:39+00:00

As is_multicast_ether_addr returns true on broadcast packets as
well, we need to explicitly exclude broadcast packets so that
they're always flooded.  This wasn't an issue before as broadcast
packets were considered to be an unregistered multicast group,
which were always flooded.  However, as we now only flood such
packets to router ports, this is no longer acceptable.

net: bind() fix error return on wrong address family

2011-07-05T04:37:41+00:00

Hi,

Reinhard Max also pointed out that the error should EAFNOSUPPORT according
to POSIX.

The Linux manpages have it as EINVAL, some other OSes (Minix, HPUX, perhaps BSD) use
EAFNOSUPPORT. Windows uses WSAEFAULT according to MSDN.

Other protocols error values in their af bind() methods in current mainline git as far
as a brief look shows:
	EAFNOSUPPORT: atm, appletalk, l2tp, llc, phonet, rxrpc
	EINVAL: ax25, bluetooth, decnet, econet, ieee802154, iucv, netlink, netrom, packet, rds, rose, unix, x25,
	No check?: can/raw, ipv6/raw, irda, l2tp/l2tp_ip

Ciao, Marcus

xfrm4: Don't call icmp_send on local error

2011-07-02T00:33:19+00:00

Calling icmp_send() on a local message size error leads to
an incorrect update of the path mtu. So use ip_local_error()
instead to notify the socket about the error.

ipv4: Don't use ufo handling on later transformed packets

2011-07-02T00:33:19+00:00

We might call ip_ufo_append_data() for packets that will be IPsec
transformed later. This function should be used just for real
udp packets. So we check for rt->dst.header_len which is only
nonzero on IPsec handling and call ip_ufo_append_data() just
if rt->dst.header_len is zero.

xfrm: Remove family arg from xfrm_bundle_ok

2011-07-02T00:33:19+00:00

The family arg is not used any more, so remove it.
