Since kernel 5.2 within netlink messages the NLA_F_NESTED nested flag is
validated. But swconfig/swlib doesn't set the flag for
SWITCH_ATTR_OP_VALUE_PORTS related netlink messages and assigning ports
to vlans via
swconfig dev switch0 vlan 1 set ports '0 1 2 3 4 6t'
Errors put with "Failed to set attribute: Invalid input data or
parameter".
Relax the validation rules and use the deprecated functions, to use the
same level of validation as it was till kernel 5.1. Depending on who has
swconfig related netlink messages implemented, there might be more
broken tools out there and we should keep backward compatibility if
possible.

This commit fixes a bug in the main swconfig patch where a function
needed by the b53 driver is not exported.
Additionally it adds OF support to the b53_mdio driver for devicetree-
based probing

This adds initial support for kernel 4.14 based on the patches for
kernel 4.9.
In the configuration I deactivated some of the new possible security
features like:
CONFIG_REFCOUNT_FULL
CONFIG_SLAB_FREELIST_HARDENED
CONFIG_SOFTLOCKUP_DETECTOR
CONFIG_WARN_ALL_UNSEEDED_RANDOM
And these overlay FS options are also deactivated:
CONFIG_OVERLAY_FS_INDEX
CONFIG_OVERLAY_FS_REDIRECT_DIR
I activated this:
CONFIG_FORTIFY_SOURCE
CONFIG_POSIX_TIMERS
CONFIG_SLAB_MERGE_DEFAULT
CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED
I am not sure if I did the porting correct for the following patches:
target/linux/generic/backport-4.14/020-backport_netfilter_rtcache.patch

CHROMIUM: net: ar8216: address security vulnerabilities in swconfig & ar8216
This patch does the following changes:
*address the security vulnerabilities in both swconfig framework and in
ar8216 driver (many bound check additions, and turned swconfig structure
signed element into unsigned when applicable)
*address a couple of whitespaces and indendation issues

The swconfig kernel infrastructure fails to do any permissions checks when
changing settings. As such an ordinary user account on a device with a
switch can change switch settings without any special permissions.
Routers generally have few non-admin users so this isn't a big hole, but it
is a security hole. Likely the greatest danger is for multifunction devices
which have a lot of extra daemons, compromising a low-security daemon would
allow one to modify switch settings and cause the router/switch to appear to
lock-up (or cause other sorts of troublesome nyetwork behavior).
Implement a check for CAP_NET_ADMIN in swconfig_set_attr() and deny any
requests originating from user contexts lacking this capability.

It's quite common for switches to have PHY per port so adding a generic
helper setting link state will help many drivers. It just needs an API
to access PHYs which this patch also adds.

As explained earlier, using SWITCH_TYPE_LINK gives more flexibility,
it doesn't require e.g. string parsing to read some data.

So far we were sending link data as a string. It got some drawbacks:
1) Didn't allow writing clean user space apps reading link state. It was
needed to do some screen scraping.
2) Forced whole PORT_LINK communication to be string based. Adding
support for *setting* port link required passing string and parting
it in the kernel space.

If EEE is autonegotiated between the link partners, display

swconfig does not compile with 3.7 because
struct netlink_notify->pid has been renamed to
struct netlink_notify->portid
