Suppose you have a map array value that is something like this

struct foo {
	unsigned iter;
	int array[SOME_CONSTANT];
};

You can easily insert this into an array, but you cannot modify the contents of
foo->array[] after the fact.  This is because we have no way to verify we won't
go off the end of the array at verification time.  This patch provides a start
for this work.  We accomplish this by keeping track of a minimum and maximum
value a register could be while we're checking the code.  Then at the time we
try to do an access into a MAP_VALUE we verify that the maximum offset into that
region is a valid access into that memory region.  So in practice, code such as
this

unsigned index = 0;

if (foo->iter >= SOME_CONSTANT)
	foo->iter = index;
else
	index = foo->iter++;
foo->array[index] = bar;

would be allowed, as we can verify that index will always be between 0 and
SOME_CONSTANT-1.  If you wish to use signed values you'll have to have an extra
check to make sure the index isn't less than 0, or do something like index %=
SOME_CONSTANT.

The current code changes txhash (flowlables) on every retransmitted
SYN/ACK, but only after the 2nd retransmitted SYN and only after
tcp_retries1 RTO retransmits.

With this patch:
1) txhash is changed with every SYN retransmits
2) txhash is changed with every RTO.

The result is that we can start re-routing around failed (or very
congested paths) as soon as possible. Otherwise application health
checks may fail and the connection may be terminated before we start
to change txhash.

v4: Removed sysctl, txhash is changed for all RTOs

====================
fib offload: switch to notifier

The goal of this patchset is to allow driver to propagate all prefixes
configured in kernel down HW. This is necessary for routing to work
as expected. If we don't do that HW might forward prefixes known to kernel
incorrectly. Take an example when default route is set in switch HW and there
is an IP address set on a management (non-switch) port.

Currently, only FIB entries related to the switch port netdev are
offloaded using switchdev ops. This model is not extendable so the
first patch introduces a replacement: notifier to propagate FIB entry
additions and removals to whoever is interested.

The second patch introduces couple of helpers to deal with RTNH_F_OFFLOAD
flags. Currently it is set in switchdev core. There the assumption is
that only one offload device exists. But for FIB notifier, we assume
multiple offload devices. So the patch introduces a per FIB entry
reference counter and helpers use it in order to achieve this:
   0 means RTNH_F_OFFLOAD is not set, no device offloads this entry
   n means RTNH_F_OFFLOAD is set and the entry is offloaded by n devices

Patches 3 and 4 convert mlxsw and rocker to adopt this new way, registering
one notifier block for each asic instance. Both of these patches also
implement internal "abort" mechanism.

Using switchdev ops, "abort" is called by switchdev core whenever there is
an error during FIB entry add offload. This leads to removal of all
offloaded entries on system by fib_trie code.

Now the new notifier assumes the driver takes care of the abort action.
Here's why:
1) The fact that one HW cannot offload an entry does not mean that the
   others can't do it. So let only one entity to abort and leave the rest
   to work happily.
2) The driver knows what to in order to properly abort. For example,
   currently abort is broken for mlxsw, as for Spectrum there is a need
   to set 0.0.0.0/0 trap in RALUE register.

The fifth patch removes the old, no longer used FIB offload infrastructure.

The last patch reflects the changes into switchdev documentation file.

net: bcmgenet: only use new api ethtool_{get|set}_link_ksettings

Some times ago, a serie of patches were committed :
- commit 62469c76 ("net: ethernet: bcmgenet: use phydev from struct net_device")
- commit 6b352ebc ("net: ethernet: broadcom: bcmgenet: use new api ethtool_{get|set}_link_ksettings")
The first patch add a regression on this driver, so it should be reverted.
As the second patch depend on the former, it should be reverted too.

The first patch is buggy because there is a "trick" in this driver.
The structure phydev is kept in the private data when the interface
go down, and used when the interface go up to enable the phy before
the function phy_connect is called.

I don't have this hardware, neither the datasheet. So I won't
update the driver to avoid this trick.

But the real goal of the first serie was to move to the new api
ethtool_{get|set}_link_ksettings. So I provide a new version of
the patch without the "cleaning" of driver to use the phydev
store in the net_device structure.

Changelog:
v3:
- use priv instead of dev (so all the code use the same phydev)
v2:
- use Florian Fainelli patches for the revert instead of Jaedon Shin
- simply use net: bcmgenet: for the prefix of the patch

This was previously fixed by commit 5dbebbb4 ("net: bcmgenet:
Software reset EPHY after power on") but the commit we are reverting was
essentially making this previous commit void, here is why.

Without commit 62469c76 we would have the following scenario after
an ifconfig down then up sequence:

- bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is
  initialized *before* we get to initialize the UniMAC, this is
  critical to ensure the PHY is in a correct state, priv->phydev is
  valid, this code executes fine

- second time from bcmgenet_mii_probe(), through the normal
  phy_init_hw() call (which arguably could be optimized out)

Everything is fine in that case. With commit 62469c76, we would have
the following scenario to happen after an ifconfig down then up
sequence:

- bcmgenet_close() calls phy_disonnect() which makes dev->phydev become
  NULL

- when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from
  bcmgenet_power_up() to initialize the internal PHY, the NULL check
  becomes true, so we do not reset the PHY, yet we keep going on and
  initialize the UniMAC, causing MAC activity to occur

- we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is
  too late, the PHY is botched, and causes the above bogus pings/packets
  transmission/reception to occur

This prevent future potential pointer leaks when an unprivileged eBPF
program will read a pointer value from its context. Even if
is_valid_access() returns a pointer type, the eBPF verifier replace it
with UNKNOWN_VALUE. The register value that contains a kernel address is
then allowed to leak. Moreover, this fix allows unprivileged eBPF
programs to use functions with (legitimate) pointer arguments.

Not an issue currently since reg_type is only set for PTR_TO_PACKET or
PTR_TO_PACKET_END in XDP and TC programs that can only be loaded as
privileged. For now, the only unprivileged eBPF program allowed is for
socket filtering and all the types from its context are UNKNOWN_VALUE.
However, this fix is important for future unprivileged eBPF programs
which could use pointers in their context.

I stumbled over a new warning during randconfig testing,
with CONFIG_BPF_SYSCALL disabled:

As far as I can tell, this is a false positive caused by the compiler
getting confused about a function that is partially inlined, but it's
easy to avoid while improving the code:

The nfp_bpf_jit() stub helper for that configuration is unusual as it
is defined in a header file but not marked 'static inline'. By moving
the compile-time check into the caller using the IS_ENABLED() macro,
we can remove that stub and simplify the nfp_net_bpf_offload_prepare()
function enough to unconfuse the compiler.

We get 1 warning when building kernel with W=1:
drivers/net/ethernet/broadcom/genet/bcmgenet.c:2763:5: warning: no previous prototype for 'bcmgenet_hfb_add_filter' [-Wmissing-prototypes]

In fact, this function is implemented in
drivers/net/ethernet/broadcom/genet/bcmgenet.c, but be called
by no one, thus can be removed.

So this patch removes the unused functions.

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.
