Commit 55cd48c821 ("net: fec: stop the "rcv is not +last, " error

Coldfire.

Move the FEC_FTRL register access inside the FEC_QUIRK_HAS_RACC 'if' block,

13a7ebb38a net: dsa: mv88e6xxx: Clear the PDOWN bit on setup
Some of the vendor-specific bootloaders set up this part
of the initialization for us, so this was never added.
However, since upstream bootloaders don't initialize the
chip specifically, they leave the fiber MII's PDOWN flag
set, which means that the CPU port doesn't connect.

This patch checks whether this flag has been clear prior
by something else, and if not make us clear it.

836b34a935 ALSA: usb-audio: Fix double-free in error paths after snd_usb_add_audio_stream() call
create_fixed_stream_quirk(), snd_usb_parse_audio_interface() and
create_uaxx_quirk() functions allocate the audioformat object by themselves
and free it upon error before returning. However, once the object is linked
to a stream, it's freed again in snd_usb_audio_pcm_free(), thus it'll be
double-freed, eventually resulting in a memory corruption.

This patch fixes these failures in the error paths by unlinking the audioformat
object before freeing it.

Based on a patch by Takashi Iwai <tiwai@suse.de>

[Note for stable backports:
 this patch requires the commit 902eb7fd1e ('ALSA: usb-audio: Minor
 code cleanup in create_fixed_stream_quirk()')]

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2016-03-29

This series contains fixes to ixgbe and ixgbevf.

Tushar fixes an issue which was introduced with an earlier commit, where
hardware register RAR0 default MAC address does not get set properly.

Alex fixes two issues, first being the VXLAN port number should be stored
in network order instead of in host order.  The second fix corrects the ATR
code to handle IPv6 extension headers.  The issue was ATR code was assuming
that it would be able to use tcp_hdr for every TCP frame that came through,
but that is not the case, which resulted in bad filters being setup.

Mark fixes a use of usleep_range() to udelay() in the case where a lock
is being held.

Stefan fixes the offline self tests where ndo_stop() should be used instead
of ndo_close(), which causes IFF_UP to be cleared and interface routes get
removed.

Emil fixes the error case where we need to return an error when a MAC
address change is rejected by the PF.  This helps prevent the user from
modifying the MAC address when the operation is not permitted.

Sridhar provides three fixes for ixgbe, all dealing with traffic class
offload handling.

910cd32e55 parisc: Fix and enable seccomp filter support
The seccomp filter support requires careful handling of task registers.  This
includes reloading of the return value (%r28) and proper syscall exit if
secure_computing() returned -1.

Additionally we need to sign-extend the syscall number from signed 32bit to
signed 64bit in do_syscall_trace_enter() since the ptrace interface only allows
storing 32bit values in compat mode.

c0e760c9c6 bpf: make padding in bpf_tunnel_key explicit
Make the 2 byte padding in struct bpf_tunnel_key between tunnel_ttl
and tunnel_label members explicit. No issue has been observed, and
gcc/llvm does padding for the old struct already, where tunnel_label
was not yet present, so the current code works, but since it's part
of uapi, make sure we don't introduce holes in structs.

Therefore, add tunnel_ext that we can use generically in future
(f.e. to flag OAM messages for backends, etc). Also add the offset
to the compat tests to be sure should some compilers not padd the
tail of the old version of bpf_tunnel_key.

correct for now as long as we do not add any devices that support
NETIF_F_GSO_GRE_CSUM.  When such a device is added it could have the
potential to mess things up due to the fact that the outer transport header
points to the outer UDP header and not the GRE header as would be expected.

b5aea3de88 ixgbe: Fix cls_u32 offload support for L4 ports
Fix support for 16 bit source/dest port matches in ixgbe model.
u32 uses a single 32-bit key value for both source and destination ports
starting at offset 0. So replace the 2 functions with a single function
that takes this key value/mask to program both source and dest ports.

Verified with the following filter:

 #tc qdisc add dev p4p1 ingress
 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
	handle 1: u32 divisor 1

Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

e2873d43f9 ixgbe: Fix ATR so that it correctly handles IPv6 extension headers
The ATR code was assuming that it would be able to use tcp_hdr for
every TCP frame that came through.  However this isn't the case as it
is possible for a frame to arrive that is TCP but sent through something
like a raw socket.  As a result the driver was setting up bad filters in
which tcp_hdr was really pointing to the network header so the data was
all invalid.

In order to correct this I have added a bit of parsing logic that will
determine the TCP header location based off of the network header and
either the offset in the case of the IPv4 header, or a walk through the
IPv6 extension headers until it encounters the header that indicates
IPPROTO_TCP.  In addition I have added checks to verify that the lowest
protocol provided is recognized as IPv4 or IPv6 to help mitigate raw
sockets using ETH_P_ALL from having ATR applied to them.

9f12df906c ixgbe: Store VXLAN port number in network order
The VXLAN port number should be stored in network order instead of in host
order as it is accessed from the hot-path in ATR.  This way we can avoid
having to do any byte swaps in order to validate the port number.

I moved the vxlan_port value into a hole in the read-mostly region of the
adapter struct.  This way it should be in a warm cache-line instead of in
some isolated region in memory when it needs to be accessed.

In addition I went through and stripped a bunch of unneeded ifdef flags
since having an extra variable present doesn't really hurt anything and
makes the code easier to read.  I also went through and dropped the
NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides
no value as the flag is not evaluated in the Rx path.
