Currently, we have mctp_address_ok(), which checks if an EID is in the
"valid" range of 8-254 inclusive. However, 0 and 255 may also be valid
addresses, depending on context. 0 is the NULL EID, which may be set
when physical addressing is used. 255 is valid as a destination address
for broadcasts.
This change renames mctp_address_ok to mctp_address_unicast, and adds
similar helpers for broadcast and null EIDs, which will be used in an
upcoming commit.

This patch adds a new protocol attribute to IPv4 and IPv6 addresses.
Inspiration was taken from the protocol attribute of routes. User space
applications like iproute2 can set/get the protocol with the Netlink API.
The attribute is stored as an 8-bit unsigned integer.
The protocol attribute is set by kernel for these categories:
- IPv4 and IPv6 loopback addresses
- IPv6 addresses generated from router announcements
- IPv6 link local addresses
User space may pass custom protocols, not defined by the kernel.
Grouping addresses on their origin is useful in scenarios where you want
to distinguish between addresses based on who added them, e.g. kernel
vs. user space.
Tagging addresses with a string label is an existing feature that could be
used as a solution. Unfortunately the max length of a label is
15 characters, and for compatibility reasons the label must be prefixed
with the name of the device followed by a colon. Since device names also
have a max length of 15 characters, only -1 characters is guaranteed to be
available for any origin tag, which is not that much.
A reference implementation of user space setting and getting protocols
is available for iproute2:

In some graceful updates that get initially triggered by the
RESET event, especially with older firmware, the fw_generation
bits don't change but the fw_status is seen to go to 0 then back
to 1. However, the driver didn't perform the restart, remained
waiting for fw_generation to change, and got left in limbo.
This is because the clearing of idev->fw_status_ready to 0
didn't happen correctly as it was buried in the transition
trigger: since the transition down was triggered not here
but in the RESET event handler, the clear to 0 didn't happen,
so the transition back to 1 wasn't detected.
Fix this particular case by bringing the setting of
idev->fw_status_ready back out to where it was before.

IPv6 has this hack changing sk->sk_prot when an IPv6 socket
is 'converted' to an IPv4 one with IPV6_ADDRFORM option.
This operation is only performed for TCP and UDP, knowing
their 'struct proto' for the two network families are populated
in the same way, and can not disappear while a reader
might use and dereference sk->sk_prot.
If we think about it all reads of sk->sk_prot while
either socket lock or RTNL is not acquired should be using READ_ONCE().
Also note that other layers like MPTCP, XFRM, CHELSIO_TLS also
write over sk->sk_prot.

So this loop allocates more than 9 Mo of memory.

This patch added the data checksum error mib counters check for the
script mptcp_connect.sh when the data checksum is enabled.
In do_transfer(), got the mib counters twice, before and after running
the mptcp_connect commands. The latter minus the former is the actual
number of the data checksum mib counter.
The output looks like this:
ns1 MPTCP -> ns2 (dead:beef:1::2:10007) MPTCP (duration 86ms) [ OK ]
ns1 MPTCP -> ns2 (10.0.2.1:10008 ) MPTCP (duration 66ms) [ FAIL ]

With the increase number of tests, one CI instance, using a debug kernel
config and not recent hardware, takes around 10 minutes to execute the
slowest MPTCP test: mptcp_join.sh.
Even if most CIs don't take that long to execute these tests --
typically max 10 minutes to run all selftests -- it will help some of
them if the timeout is increased.
The timeout could be disabled but it is always good to have an extra
safeguard, just in case.
Please note that on slow public CIs with kernel debug settings, it has
been observed it can easily take up to 45 minutes to execute all tests
in this very slow environment with other jobs running in parallel.
The slowest test, mptcp_join.sh takes ~30 minutes in this case.
In such environments, the selftests timeout set in the 'settings' file
is disabled because this environment is known as being exceptionnally
slow. It has been decided not to take such exceptional environments into
account and set the timeout to 20min.

bpf_prog_pack_free() uses header->size to decide whether the header
should be freed with module_memfree() or the bpf_prog_pack logic.
However, in kvmalloc() failure path of bpf_jit_binary_pack_alloc(),
header->size is not set yet. As a result, bpf_prog_pack_free() may treat
a slice of a pack as a standalone kvmalloc'd header and call
module_memfree() on the whole pack. This in turn causes use-after-free by
other users of the pack.
Fix this by setting ro_header->size before freeing ro_header.

- Support "rt_trap", "rt_offload", "rt_offload_failed" flags
- Handle case, when route in "local" table overlaps route in "main" table
example:
ip ro add blackhole 7.7.7.7
ip ro add local 7.7.7.7 dev sw1p30
# blackhole route will be deoffloaded. rt_offload flag disappeared
Limitations:
- Only "blackhole" and "local" routes supported. "nexthop" routes is TRAP
for now and will be implemented soon.
- Only "local" and "main" tables supported

Add functions to create/delete lpm entry in hw.
prestera_hw_lpm_add() take index of allocated virtual router.
Also it takes grp_id, which is index of allocated nexthop group.
ABI to create nexthop group will be added soon.

In __bond_release_one(), bond_set_carrier() is only called when bond
device has no slave. Therefore, if we remove the up slave from a master
with two slaves and keep the down slave, the master will remain up.
Fix this by moving bond_set_carrier() out of if (!bond_has_slaves(bond))
statement.
Reproducer:
$ insmod bonding.ko mode=0 miimon=100 max_bonds=2
$ ifconfig bond0 up
$ ifenslave bond0 eth0 eth1
$ ifconfig eth0 down
$ ifenslave -d bond0 eth1
$ cat /proc/net/bonding/bond0

syzbot reported various soft lockups caused by bpf batch operations.
INFO: task kworker/1:1:27 blocked for more than 140 seconds.
INFO: task hung in rcu_barrier
Nothing prevents batch ops to process huge amount of data,
we need to add schedule points in them.
Note that maybe_wait_bpf_programs(map) calls from
generic_map_delete_batch() can be factorized by moving
the call after the loop.
This will be done later in -next tree once we get this fix merged,
unless there is strong opinion doing this optimization sooner.
