Commit bfe9b9d2df ("cdc_ether: Improve ZTE MF823/831/910 handling")
introduced a work-around in usbnet_cdc_status() for devices that exported
cdc carrier on twice on connect. Before the commit, this behavior caused
the link state to be incorrect. It was assumed that all CDC Ethernet
devices would either export this behavior, or send one off and then one on
notification (which seems to be the default behavior).
Unfortunately, it turns out multiple devices sends a connection
notification multiple times per second (via an interrupt), even when
connection state does not change. This has been observed with several
different USB LAN dongles (at least), for example 13b1:0041 (Linksys).
After bfe9b9d2df, the link state has been set as down and then up for
each notification. This has caused a flood of Netlink NEWLINK messages and
syslog to be flooded with messages similar to:
cdc_ether 2-1:2.0 eth1: kevent 12 may have been dropped
This commit fixes the behavior by reverting usbnet_cdc_status() to how it
was before bfe9b9d2df. The work-around has been moved to a separate
status-function which is only called when a known, affect device is
detected.
v1->v2:
* Do not open-code netif_carrier_ok() (thanks Henning Schild).
* Call netif_carrier_off() instead of usb_link_change(). This prevents
calling schedule_work() twice without giving the work queue a chance to be
processed (thanks Bjørn Mork).

When packet_set_ring creates a ring buffer it will initialize a
struct timer_list if the packet version is TPACKET_V3. This value
can then be raced by a different thread calling setsockopt to
set the version to TPACKET_V1 before packet_set_ring has finished.
This leads to a use-after-free on a function pointer in the
struct timer_list when the socket is closed as the previously
initialized timer will not be deleted.
The bug is fixed by taking lock_sock(sk) in packet_setsockopt when
changing the packet version while also taking the lock at the start
of packet_set_ring.

completion handler does the reverse, first take the private lock, then the

net: stmmac: fix probe error handling and phydev leaks
This series fixes a number of issues with the stmmac-driver probe error
handling, which for example left clocks enabled after probe failures.
The final patch fixes a failure to deregister and free any fixed-link
PHYs that were registered during probe on probe errors and on driver
unbind. It also fixes a related of-node leak on late probe errors.
This series depends on the of_phy_deregister_fixed_link() helper that
was just merged to net.
As mentioned earlier, one staging driver also suffers from a similar
leak and can be fixed up once the above mentioned helper hits mainline.

Netfilter fixes for net
This is a large batch of Netfilter fixes for net, they are:
1) Three patches to fix NAT conversion to rhashtable: Switch to rhlist

Moreover, fix wrong comparison logic in nf_nat_bysource_cmp() as this is
expecting a return value similar to memcmp(). Change location of
the nat_bysource field in the nf_conn structure to avoid zeroing
this as it breaks interaction with SLAB_DESTROY_BY_RCU and lead us
to crashes. From Florian Westphal.
2) Don't allow malformed fragments go through in IPv6, drop them,
otherwise we hit GPF, patch from Florian Westphal.
3) Fix crash if attributes are missing in nft_range, from Liping Zhang.
4) Fix arptables 32-bits userspace 64-bits kernel compat, from Hongxu Jia.
5) Two patches from David Ahern to fix netfilter interaction with vrf.
From David Ahern.
6) Fix element timeout calculation in nf_tables, we take milliseconds
from userspace, but we use jiffies from kernelspace. Patch from
Anders K. Pedersen.
7) Missing validation length netlink attribute for nft_hash, from
Laura Garcia.
8) Fix nf_conntrack_helper documentation, we don't default to off
anymore for a bit of time so let's get this in sync with the code.
I know is late but I think these are important, specifically the NAT
bits, as they are mostly addressing fallout from recent changes. I also
read there are chances to have -rc8, if that is the case, that would
also give us a bit more time to test this.

l2tp: fixes for l2tp_ip and l2tp_ip6 socket handling
This series addresses problems found while working on commit 32c231164b
("l2tp: fix racy SOCK_ZAPPED flag check in l2tp_ip{,6}_bind()").
The first three patches fix races in socket's connect, recv and bind
operations. The last two ones fix scenarios where l2tp fails to
correctly lookup its userspace sockets.
Apart from the last patch, which is l2tp_ip6 specific, every patch
fixes the same problem in the L2TP IPv4 and IPv6 code.
All problems fixed by this series exist since the creation of the
l2tp_ip and l2tp_ip6 modules.
Changes since v1:
* Patch #3: fix possible uninitialised use of 'ret' in l2tp_ip_bind().

The '!(addr && ipv6_addr_equal(addr, laddr))' part of the conditional
matches if addr is NULL or if addr != laddr.
But the intend of __l2tp_ip6_bind_lookup() is to find a sockets with
the same address, so the ipv6_addr_equal() condition needs to be
inverted.
For better clarity and consistency with the rest of the expression, the
(!X || X == Y) notation is used instead of !(X && X != Y).

When looking up an l2tp socket, we must consider a null netdevice id as
wild card. There are currently two problems caused by
__l2tp_ip_bind_lookup() not considering 'dif' as wild card when set to 0:
* A socket bound to a device (i.e. with sk->sk_bound_dev_if != 0)
never receives any packet. Since __l2tp_ip_bind_lookup() is called
with dif == 0 in l2tp_ip_recv(), sk->sk_bound_dev_if is always
different from 'dif' so the socket doesn't match.
* Two sockets, one bound to a device but not the other, can be bound
to the same address. If the first socket binding to the address is
the one that is also bound to a device, the second socket can bind
to the same address without __l2tp_ip_bind_lookup() noticing the
overlap.
To fix this issue, we need to consider that any null device index, be
it 'sk->sk_bound_dev_if' or 'dif', matches with any other value.
We also need to pass the input device index to __l2tp_ip_bind_lookup()
on reception so that sockets bound to a device never receive packets
from other devices.
This patch fixes l2tp_ip6 in the same way.

It's not enough to check for sockets bound to same address at the
beginning of l2tp_ip{,6}_bind(): even if no socket is found at that
time, a socket with the same address could be bound before we take
the l2tp lock again.
This patch moves the lookup right before inserting the new socket, so
that no change can ever happen to the list between address lookup and
socket insertion.
Care is taken to avoid side effects on the socket in case of failure.
That is, modifications of the socket are done after the lookup, when
binding is guaranteed to succeed, and before releasing the l2tp lock,
so that concurrent lookups will always see fully initialised sockets.
For l2tp_ip, 'ret' is set to -EINVAL before checking the SOCK_ZAPPED
bit. Error code was mistakenly set to -EADDRINUSE on error by commit
32c231164b ("l2tp: fix racy SOCK_ZAPPED flag check in l2tp_ip{,6}_bind()").
Using -EINVAL restores original behaviour.
For l2tp_ip6, the lookup is now always done with the correct bound
device. Before this patch, when binding to a link-local address, the
lookup was done with the original sk->sk_bound_dev_if, which was later
overwritten with addr->l2tp_scope_id. Lookup is now performed with the
final sk->sk_bound_dev_if value.
Finally, the (addr_len >= sizeof(struct sockaddr_in6)) check has been
dropped: addr is a sockaddr_l2tpip6 not sockaddr_in6 and addr_len has
already been checked at this point (this part of the code seems to have
been copy-pasted from net/ipv6/raw.c).

Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec

Fix that by caching statistics in fec_enet_private. Cache is initialized

that have been registered using the of_phy_register_fixed_link()
interface.
All but two drivers currently fail to do this and this series fixes most
of them with the exception of a staging driver and the stmmac drivers
which will be fixed by follow-on patches.
Included are also a couple of fixes for related of-node leaks.
Note that all patches except the of_mdio one have been compile-tested
only.
Also note that the series is against net due to dependencies not yet in
net-next.
