f6b1bfd17d igb: Add check for invalid size to igb_get_invariants_82575()
Recent commits have changed how EEPROM size is checked and if the size

e67f88dd12 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 :

1c2d670f36 : [RTNETLINK]: Hold rtnl_mutex during netlink dump callbacks
6313c1e099 : [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()

5615787257 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
lookup fast path to make sure these are always set.

816c04fe7e 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:

The bug was that unix domain sockets use a pseduo packet for
connecting and accept uses that psudo packet to get the socket.
In the buggy seqpacket case we were allowing unconnected
sockets to call recvmsg and try to receive the pseudo packet.

That is always wrong and as of commit 7361c36c5 the pseudo
packet had become enough different from a normal packet
that the kernel started oopsing.

Do for seqpacket_recv what was done for seqpacket_send in 2.5
and only allow it on connected seqpacket sockets.
