Shawn Guo 119fc00776 net: fec: use managed function devm_gpio_request_one
Using gpio_request_one will require the probe fail-out call gpio_free,
which is missing currently.  Change to use devm_gpio_request_one to
fix the problem.

Shawn Guo 5fa9c0fe3e net: fec: enable regulator for fec phy
If bootloader or platform initialization code does not enable the
power supply to fec phy, we need to do it in fec driver before calling
fec_reset_phy to have the phy powered on.

Shawn Guo 2ca9b2aa0d net: fec: reset phy after pinctrl setup
In case that bootloader or platform initialization does not set up
fec pins, the fec_reset_phy will not be able to succeed, because
fec_reset_phy is currently called before devm_pinctrl_get_select_default.
Move fec_reset_phy call to the place between devm_pinctrl_get_select_default
and fec_enet_init to have above case be taken care.

Michael Chan a2028b2376 cnic: Fix occasional NULL pointer dereference during reboot.
We register with bnx2x before we allocate ctx_tbl structure, so it is
possible for bnx2x to call cnic_ctl before the structure is allocated.
This can sometimes cause NULL pointer dereference of cp->ctx_tbl.  We
fix this by adding simple checking for valid state before proceeding.
The cnic_ctl call is RCU protected so we don't have to deal with race
conditions.

Because of the additional checking, we need to finish the shutdown
before clearing the CNIC_UP flag.

David S. Miller c10237e077 Revert "ipv4: tcp: dont cache unconfirmed intput dst"
This reverts commit c074da2810.

This change has several unwanted side effects:

1) Sockets will cache the DST_NOCACHE route in sk->sk_rx_dst and we'll
   thus never create a real cached route.

2) All TCP traffic will use DST_NOCACHE and never use the routing
   cache at all.

dropwatch wrongly diagnose all received UDP packets as drops.

This patch removes trace_kfree_skb() done in skb_free_datagram_locked().

Locations calling skb_free_datagram_locked() should do it on their own.

As a result, drops are accounted on the right function.

Eric Dumazet c074da2810 ipv4: tcp: dont cache unconfirmed intput dst
DDOS synflood attacks hit badly IP route cache.

On typical machines, this cache is allowed to hold up to 8 Millions dst
entries, 256 bytes for each, for a total of 2GB of memory.

rt_garbage_collect() triggers and tries to cleanup things.

Eventually route cache is disabled but machine is under fire and might
OOM and crash.

This patch exploits the new TCP early demux, to set a nocache
boolean in case incoming TCP frame is for a not yet ESTABLISHED or
TIMEWAIT socket.

This 'nocache' boolean is then used in case dst entry is not found in
route cache, to create an unhashed dst entry (DST_NOCACHE)

SYN-cookie-ACK sent use a similar mechanism (ipv4: tcp: dont cache
output dst for syncookies), so after this patch, a machine is able to
absorb a DDOS synflood attack without polluting its IP route cache.
