There is at least unlocked deletion of net->ipv4.fib_notifier_ops
from net::fib_notifier_ops:

ip_fib_net_exit()
  rtnl_unlock()
  fib4_notifier_exit()
    fib_notifier_ops_unregister(net->ipv4.notifier_ops)
      list_del_rcu(&ops->list)

So fib_seq_sum() can't use rtnl_lock() only for protection.

The possible solution could be to use rtnl_lock()
in fib_notifier_ops_unregister(), but this adds
a possible delay during net namespace creation,
so we better use rcu_read_lock() till someone
really needs the mutex (if that happens).

With commits 35e015e1 and a2d3f3e3, the global 'accept_dad' flag
is also taken into account (default value is 1). If either global or
per-interface flag is non-zero, DAD will be enabled on a given interface.

This is not backward compatible: before those patches, the user could
disable DAD just by setting the per-interface flag to 0. Now, the
user instead needs to set both flags to 0 to actually disable DAD.

Restore the previous behaviour by setting the default for the global
'accept_dad' flag to 0. This way, DAD is still enabled by default,
as per-interface flags are set to 1 on device creation, but setting
them to 0 is enough to disable DAD on a given interface.

- Before 35e015e1f57a7 and a2d3f3e3:
          global    per-interface    DAD enabled
[default]   1             1              yes
            X             0              no
            X             1              yes

- After 35e015e1 and a2d3f3e3:
          global    per-interface    DAD enabled
[default]   1             1              yes
            0             0              no
            0             1              yes
            1             0              yes

- After this fix:
          global    per-interface    DAD enabled
            1             1              yes

iOS devices require the host to be "trusted" before servicing network
packets. Establishing trust requires the user to confirm a dialog on the
iOS device.Until trust is established, the iOS device will silently discard
network packets from the host. Currently, the ipheth driver does not detect
whether an iOS device has established trust with the host, and immediately
sets up the transmit queues.

This causes the following problems:

- Kernel taint due to WARN() in netdev watchdog.
- Dmesg spam ("TX timeout").
- Disruption of user space networking activity (dhcpd, etc...) when new
interface comes up but cannot be used.
- Unnecessary host and device wakeups and USB traffic

[ 1101.320110] ipheth 1-5:4.2: ipheth_tx_timeout: TX timeout

The last message "TX timeout" is repeated every 5 seconds until trust is
established or the device is disconnected, filling up dmesg.

The proposed patch eliminates the problem by, upon connection, keeping the
TX queue and carrier disabled until a packet is first received from the iOS
device. This is reflected by the confirmed_pairing variable in the device
structure. Only after at least one packet has been received from the iOS
device, the transmit queue and carrier are brought up during the periodic
device poll in ipheth_carrier_set. Because the iOS device will always send
a packet immediately upon trust being established, this should not delay
the interface becoming useable. To prevent failed UBRs in
ipheth_rcvbulk_callback from perpetually re-enabling the queue if it was
disabled, a new check is added so only successful transfers re-enable the
queue, whereas failed transfers only trigger an immediate poll.

This has the added benefit of removing the periodic control requests to the
iOS device until trust has been established and thus should reduce wakeup
events on both the host and the iOS device.

The LPI transitioning logic in stmmac_main uses
priv->tx_path_in_lpi_mode to enter/exit LPI.

However, priv->tx_path_in_lpi_mode is assigned
using the return value from host_irq_status().

So for dwmac4, priv->tx_path_in_lpi_mode was always false,
so stmmac_tx_clean() would always try to put us in eee mode,
and stmmac_xmit() would never take us out of eee mode.

To fix this, make host_irq_status() read and return the LPI
irq status also for dwmac4.

This also increments the existing LPI counters, so that
ethtool --statistics shows LPI transitions also for dwmac4.

For dwmac1000, irqs are enabled/disabled using the register
named "Interrupt Mask Register", and thus setting a bit disables
that specific irq.

For dwmac4 the matching register is named "MAC_Interrupt_Enable",
and thus setting a bit enables that specific irq.

Looking at dwmac1000_core.c, the irqs that are always enabled are:
LPI and PMT.

Looking at dwmac4_core.c, the irqs that are always enabled are:
PMT.

To be able to read the LPI irq status, we need to enable the LPI
irq also for dwmac4.

The mvneta controller provides a 8-bit register to update the pending
Tx descriptor counter. Then, a maximum of 255 Tx descriptors can be
added at once. In the current code the mvneta_txq_pend_desc_add function
assumes the caller takes care of this limit. But it is not the case. In
some situations (xmit_more flag), more than 255 descriptors are added.
When this happens, the Tx descriptor counter register is updated with a
wrong value, which breaks the whole Tx queue management.

This patch fixes the issue by allowing the mvneta_txq_pend_desc_add

net: core: devname allocation cleanups

It's somewhat confusing to have both dev_alloc_name and
dev_get_valid_name. I can't see why the former is less strict than the
latter, so make them (or rather dev_alloc_name_ns and
dev_get_valid_name) equivalent, hardening dev_alloc_name() a little.

Obvious follow-up patches would be to only export one function, and
make dev_alloc_name a static inline wrapper for that (whichever name
is chosen for the exported interface). But maybe there is a good
reason the two exported interfaces do different checking, so I'll
refrain from including the trivial but tree-wide renaming in this
series.

The only caller passes a stack buffer as buf, so it won't equal the
passed-in name. Moreover, we're already using buf as a scratch buffer
inside the if (p) {} block, so if buf and name were the same, that
snprintf() call would be overwriting its own format string.

dev_alloc_name contained a BUG_ON(), which I moved to dev_alloc_name_ns;
the only other caller of that already has the same BUG_ON.

__dev_alloc_name is called from the public (and exported)
dev_alloc_name(), so we don't have a guarantee that strlen(name) is at
most IFNAMSIZ. If somebody manages to get __dev_alloc_name called with a
% char beyond the 31st character, we'd be making a snprintf() call that
will very easily crash the kernel (using an appropriate %p extension,
we'll likely dereference some completely bogus pointer).

In the normal case where strlen() is sane, we don't even save anything
by limiting to IFNAMSIZ, so just use strchr().

tls: Miscellaneous fixes

Here's a set of miscellaneous fix patches.

Patch 1 makes sure aead_request is initailized properly.
Patches 2-3 Fix a memory leak we've encountered.
patch 4 moves tls_make_aad to allow sharing it in the future.
Patch 5 fixes a TOCTOU issue reported here:
https://www.spinics.net/lists/kernel/msg2608603.html
Patch 6 Avoids callback overriding when tls_set_sw_offload fails.

If we fail to enable tls in the kernel we shouldn't override
the sk_write_space callback

Avoid copying crypto_info again after cipher_type check
to avoid a TOCTOU exploits.
The temporary array on the stack is removed as we don't really need it

move tls_make_aad as it is going to be reused
by the device offload code and rx path.
Remove unused recv parameter.
