Rafał Miłecki 0ea6f0c582 bcma: move flash detection code to ChipCommon core driver
Flashes are attached and accessible through ChipCommon core, they aren't
connected to MIPS one. Moreover some new ARM devices (e.g. BCM47189) may
have serial flash accessibility using ChipCommon registers as well. To
support them we can't keep this code in MIPS core driver.

Rafał Miłecki d6a3b51ada bcma: move parallel flash support to separated file
This follows the way of handling other flashes and cleans code a bit. As
next task we will want to move flash code to ChipCommon driver as:
1) Flash controllers are accesible using ChipCommon registers
2) This code isn't MIPS specific
This change prepares bcma for that.

Colin Ian King 2b02a36d12 mt7601u: do not free dma_buf when ivp allocation fails
If the allocation of ivp fails the error handling attempts to
free an uninitialized dma_buf; this data structure just contains
garbage on the stack, so the freeing will cause issues when the
urb, buf and dma fields are free'd. Fix this by not free'ing the
dma_buf if the ivp allocation fails.

To make sure the order of sending eapol and configuring key is done

to 50 msec, which is not always enough. Especially in AP mode and
key updates the timeout may need to be much longer because client(s)
can be in powersave. Increase the timeout from 50 to 950 msec.

Until now, we have kept a pre-allocated protocol message header
aggregated into struct tipc_link. Apart from adding unnecessary
footprint to the link instances, this requires extra code both to
initialize and re-initialize it.

We now remove this sub-optimization. This change also makes it
possible to clean up the function tipc_build_proto_msg() and remove
a couple of small functions that were accessing the mentioned header.
In particular, we can replace all occurrences of the local function
call link_own_addr(link) with the generic tipc_own_addr(net).

This will lead to a nullptr exception when we process a

subscription is passed to tipc_nametbl_subscribe() resulting
in exception.

In this commit, we call tipc_nametbl_subscribe() only for
a valid subscription.

Phil Sutter 44ef548f4f net: sched: fix act_ipt for LOG target
Before calling the destroy() or target() callbacks, the family parameter
field has to be initialized. Otherwise at least the LOG target will
refuse to work and upon removal oops the kernel.

Richard Alpe ddb3712552 tipc: safely copy UDP netlink data from user
The netlink policy for TIPC_NLA_UDP_LOCAL and TIPC_NLA_UDP_REMOTE
is of type binary with a defined length. This causes the policy
framework to threat the defined length as maximum length.

There is however no protection against a user sending a smaller
amount of data. Prior to this patch this wasn't handled which could
result in a partially incomplete sockaddr_storage struct containing
uninitialized data.

In this patch we use nla_memcpy() when copying the user data. This
ensures a potential gap at the end is cleared out properly.

This was found by Julia with Coccinelle tool.

Richard Alpe 2837f39c7c tipc: don't check link reset on non existing link
Make sure we have a link before checking if it has been reset or not.

Prior to this patch tipc_link_is_reset() could be called with a non
existing link, resulting in a null pointer dereference.

Richard Alpe 9b3009604b tipc: add net device to skb before UDP xmit
Prior to this patch enabling a IPv4 UDP bearer caused a null pointer
dereference in iptunnel_xmit_stats(), when it tried to dereference the
net device from the skb. To resolve this we now point the skb device
to the net device resolved from the routing table.
