inet: Pass flowi to ->queue_xmit().

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.

ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.

Operation order is now transposed, we first create the child
socket then we try to hook up the route.

Signed-off-by: David S. Miller <davem@davemloft.net>

ipv4: Create inet_csk_route_child_sock().

This is just like inet_csk_route_req() except that it operates after
we've created the new child socket.

In this way we can use the new socket's cork flow for proper route
key storage.

This will be used by DCCP and TCP child socket creation handling.

sctp: Store a flowi in transports to provide persistent keying.

Several future simplifications are possible now because of this.

For example, the sctp_addr unions can simply refer directly to
the flowi information.

ipv4: Use cork flow in ip_queue_xmit()

All invokers of ip_queue_xmit() must make certain that the
socket is locked.  All of SCTP, TCP, DCCP, and L2TP now make
sure this is the case.

Therefore we can use the cork flow during output route lookup in
ip_queue_xmit() when the socket route check fails.

Signed-off-by: David S. Miller <davem@davemloft.net>

ipv4: Use cork flow in inet_sk_{reselect_saddr,rebuild_header}()

These two functions must be invoked only when the socket is locked
(because socket identity modifications are made non-atomically).

Therefore we can use the cork flow for output route lookups.

Signed-off-by: David S. Miller <davem@davemloft.net>

ipv4: Lock socket and use cork flow in ip4_datagram_connect().

This is to make sure that an l2tp socket's inet cork flow is
fully filled in, when it's encapsulated in UDP.

Signed-off-by: David S. Miller <davem@davemloft.net>

l2tp: Use cork flow in l2tp_ip_connect() and l2tp_ip_sendmsg()

Now that the socket is consistently locked in these two routines,
this transformation is legal.

Signed-off-by: David S. Miller <davem@davemloft.net>

l2tp: Fix locking in l2tp_core.c

l2tp_xmit_skb() must take the socket lock.  It makes use of ip_queue_xmit()
which expects to execute in a socket atomic context.

Since we execute this function in software interrupts, we cannot use the
usual lock_sock()/release_sock() sequence, instead we have to use
bh_lock_sock() and see if a user has the socket locked, and if so drop
the packet.

l2tp: Fix locking in l2tp_ip.c

Both l2tp_ip_connect() and l2tp_ip_sendmsg() must take the socket
lock.  They both modify socket state non-atomically, and in particular
l2tp_ip_sendmsg() increments socket private counters without using
atomic operations.

tcp: Use cork flow in tcp_v4_connect()

batman-adv: Avoid deadlock between rtnl_lock and s_active

The hard_if_event is called by the notifier with rtnl_lock and tries to
remove sysfs entries when a NETDEV_UNREGISTER event is received. This
will automatically take the s_active lock.

The s_active lock is also used when a new interface is added to a meshif
through sysfs. In that situation we cannot wait for the rntl_lock before
creating the actual batman-adv interface to prevent a deadlock. It is
still possible to try to get the rtnl_lock and immediately abort the
current operation when the trylock call failed.

Signed-off-by: Sven Eckelmann <sven@narfation.org>

batman-adv: Remove unnecessary hardif_list_lock

hardif_list_lock is unneccessary because we already ensure that no
multiple admin operations can take place through rtnl_lock.
hardif_list_lock only adds additional overhead and complexity.

Critical functions now check whether they are called with rtnl_lock
using ASSERT_RTNL.

It indirectly fixes the problem that orig_hash_del_if() expects that
only one interface is deleted from hardif_list at a time, but
hardif_remove_interfaces() removes all at once and then calls
orig_hash_del_if().

net: Add sendmmsg socket system call

This patch adds a multiple message send syscall and is the send
version of the existing recvmmsg syscall. This is heavily
based on the patch by Arnaldo that added recvmmsg.

I wrote a microbenchmark to test the performance gains of using
this new syscall:

http://ozlabs.org/~anton/junkcode/sendmmsg_test.c

The test was run on a ppc64 box with a 10 Gbit network card. The
benchmark can send both UDP and RAW ethernet packets.

usbnet: runtime pm: fix out of memory

This patch makes use of the EVENT_DEV_OPEN flag introduced recently to
fix one out of memory issue, which can be reproduced on omap3/4 based
pandaboard/beagle XM easily with steps below:

- enable runtime pm
echo auto > /sys/devices/platform/usbhs-omap.0/ehci-omap.0/usb1/1-1/1-1.1/power/control

- ifconfig eth0 up

- then out of memroy happened, see [1] for kernel message.

Follows my analysis:
- 'ifconfig eth0 up' brings eth0 out of suspend, and usbnet_resume
is called to schedule dev->bh, then rx urbs are submited to prepare for
recieving data;

- some usbnet devices will produce garbage rx packets flood if
info->reset is not called in usbnet_open.

- so there is no enough chances for usbnet_bh to handle and release
recieved skb buffers since many rx interrupts consumes cpu, so out of memory
for atomic allocation in rx_submit happened.

This patch fixes the issue by simply not allowing schedule of usbnet_bh until device
is opened.

mac80211: Fix a warning due to skipping tailroom reservation for IV

The devices that require IV generation in software need tailroom
reservation  for ICVs used in TKIP or WEP encryptions.
Currently, decision to skip the tailroom reservation in the tx
path was taken only on whether driver wants MMIC to be generated
in software or not. Following patch appends IV generation check for
such decisions and fixes the following warning.

net: ip_expire() must revalidate route

Commit 4a94445c9a5c (net: Use ip_route_input_noref() in input path)
added a bug in IP defragmentation handling, in case timeout is fired.

When a frame is defragmented, we use last skb dst field when building
final skb. Its dst is valid, since we are in rcu read section.

But if a timeout occurs, we take first queued fragment to build one ICMP
TIME EXCEEDED message. Problem is all queued skb have weak dst pointers,
since we escaped RCU critical section after their queueing. icmp_send()
might dereference a now freed (and possibly reused) part of memory.

Calling skb_dst_drop() and ip_route_input_noref() to revalidate route is
the only possible choice.

PCIe connections should be expressed as GT/s (GigaTransfers per second)

incorrect because (due to PCIe gen 1 & 2 having a 20% overhead) the

ixgbe: improve EEPROM read/write operations

Introduce buffered read/writes which greatly improves performance on
parts with large EEPROMs.

Previously reading/writing a word requires taking/releasing of synchronization
semaphores which adds 10ms to each operation. The optimization is to
read/write in buffers, but make sure the semaphore is not held for >500ms
according to the datasheet.

Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is
used to discover the EEPROM size when needed and keeps the result in
word_page_size for the rest of the run time.

Use buffered reads for ethtool -e.

net: dont hold rtnl mutex during netlink dump callbacks

Four years ago, Patrick made a change to hold rtnl mutex during netlink
dump callbacks.

I believe it was a wrong move. This slows down concurrent dumps, making
good old /proc/net/ files faster than rtnetlink in some situations.

This occurred to me because one "ip link show dev ..." was _very_ slow
on a workload adding/removing network devices in background.

All dump callbacks are able to use RCU locking now, so this patch does
roughly a revert of commits :

1c2d670f366 : [RTNETLINK]: Hold rtnl_mutex during netlink dump callbacks
6313c1e0992 : [RTNETLINK]: Remove unnecessary locking in dump callbacks

This let writers fight for rtnl mutex and readers going full speed.

It also takes care of phonet : phonet_route_get() is now called from rcu
read section. I renamed it to phonet_route_get_rcu()

ipv4: Make sure flowi4->{saddr,daddr} are always set.

Slow path output route resolution always makes sure that
->{saddr,daddr} are set, and also if we trigger into IPSEC resolution
we initialize them as well, because xfrm_lookup() expects them to be
fully resolved.

But if we hit the fast path and flowi4->flowi4_proto is zero, we won't
do this initialization.

Therefore, move the IPSEC path initialization to the route cache

mac80211: consolidate MIC failure report handling

Currently, mac80211 handles MIC failures differently
depending on whenever they are detected by the stack's
own software crypto or when are handed down from the
driver.

This patch tries to unify both by moving the special
branch out of mac80211 rx hotpath and into into the
software crypto part. This has the advantage that we
can run a few more sanity checks on the data and verify
if the key type was TKIP. This is very handy because
several devices generate false postive MIC failure
reports. Like carl9170, ath9k and wl12xx:
