Add MDIO bus multiplexer support for iProc SoCs
Broadcom iProc based SoCs use a MDIO bus multiplexer where child buses
could be internal as well external to SoCs. These buses could supports
MDIO transaction compatible to C-22/C-45.
Broadcom MDIO bus multiplexer is an integrated multiplexer where child bus
selection and mdio transaction logic lies inside multiplexer itself.
To accommodate this multiplexer in existing mux framework below changes
were required-
1. Passed MDIO parent bus via mdio_mux_init to MDIO mux framework.
This patch set includes MDIO bus multiplexer driver along with above
framework change. It includes one external bus node having Ethernet PHY
attached and two internal bus node holding PCIe PHYs.
This patch series is based on v4.7-rc1 and is available from github-
repo: https://github.com/Broadcom/arm64-linux.git
branch:mdio-mux-v5
-Changes from v4:
- disabled PCIe PHYs from dtsi and enabled in dts file.
-Changes from v3:
- Unregister and free the parent MDIO bus.
- rebased on net-next/master branch.
Reason for resend:
-Rebased on v4.7-rc1
Changes from v2:
-Addressed Rob's comments in this patch regarding typo/grammers.
-Addressed David's comments regarding local variables order.
-Removed property "mdio-integrated-mux" and used mdiobus_register()
in place of of_mdiobus_regsiter().
-removed usage of IS_ERR_OR_NULL to IS_ERR in PCIe PHY driver.
Changes from v1:
- stop using "brcm,is_c45" from bus node as suggested by Andrew. MDIO
PHY driver will logically OR MII_ADDR_C45 into the address when issues
any C45 MDIO read/write transaction.

Now sctp doesn't change socket state upon shutdown reception. It changes
just the assoc state, even though it's a TCP-style socket.
For some cases, if we really need to check sk->sk_state, it's necessary to
fix this issue, at least when we use ss or netstat to dump, we can get a
more exact information.
As an improvement, we will change sk->sk_state when we change asoc->state
to SHUTDOWN_RECEIVED, and also do it in sctp_shutdown to keep consistent

Add support for JMP_CALL_X (tail call) introduced by commit 04fd61ab36
("bpf: allow bpf programs to tail-call other bpf programs").
bpf_tail_call() arguments:
ctx - context pointer passed to next program
array - pointer to map which type is BPF_MAP_TYPE_PROG_ARRAY
index - index inside array that selects specific program to run
In this implementation arm64 JIT jumps into callee program after prologue,
so callee program reuses the same stack. For tail_call_cnt, we use the
callee-saved R26 (which was already saved/restored but previously unused
by JIT).
With this patch a tail call generates the following code on arm64:
if (index >= array->map.max_entries)
goto out;
34: mov x10, #0x10 // #16
38: ldr w10, [x1,x10]
3c: cmp w2, w10
40: b.ge 0x0000000000000074
if (tail_call_cnt > MAX_TAIL_CALL_CNT)

48: cmp x26, x10
4c: b.gt 0x0000000000000074

Limit the socket incoming call backlog queue size so that a remote client
can't pump in sufficient new calls that the server runs out of memory. Note
that this is partially theoretical at the moment since whilst the number of
calls is limited, the number of packets trying to set up new calls is not.
This will be addressed in a later patch.
If the caller of listen() specifies a backlog INT_MAX, then they get the
current maximum; anything else greater than max_backlog or anything
negative incurs EINVAL.
The limit on the maximum queue size can be set by:
echo N >/proc/sys/net/rxrpc/max_backlog
where 4<=N<=32.
Further, set the default backlog to 0, requiring listen() to be called
before we start actually queueing new calls. Whilst this kind of is a
change in the UAPI, the caller can't actually *accept* new calls anyway
unless they've first called listen() to put the socket into the LISTENING
state - thus the aforementioned new calls would otherwise just sit there,
eating up kernel memory. (Note that sockets that don't have a non-zero
service ID bound don't get incoming calls anyway.)
Given that the default backlog is now 0, make the AFS filesystem call
kernel_listen() to set the maximum backlog for itself.
Possible improvements include:
(1) Trimming a too-large backlog to max_backlog when listen is called.
(2) Trimming the backlog value whenever the value is used so that changes
to max_backlog are applied to an open socket automatically. Note that
the AFS filesystem opens one socket and keeps it open for extended
periods, so would miss out on changes to max_backlog.
(3) Having a separate setting for the AFS filesystem.

Add a possibility where the user can just specify the parent and
all filters under that parent are then being purged. Currently,
for example for scripting, one needs to specify pref/prio to have
a well-defined number for 'tc filter del' command for addressing
the previously created instance or additionally filter handle in
case of priorities being the same. Improve usage by allowing the
option for tc to specify the parent and removing the whole chain
for that given parent.
Example usage after patch, no tc changes required:
# tc qdisc replace dev foo clsact
# tc filter add dev foo egress bpf da obj ./bpf.o
# tc filter add dev foo egress bpf da obj ./bpf.o
# tc filter show dev foo egress
filter protocol all pref 49151 bpf
filter protocol all pref 49151 bpf handle 0x1 bpf.o:[classifier] direct-action
filter protocol all pref 49152 bpf
filter protocol all pref 49152 bpf handle 0x1 bpf.o:[classifier] direct-action
# tc filter del dev foo egress
# tc filter show dev foo egress
#
Previously, RTM_DELTFILTER requests with invalid prio of 0 were
rejected, so only netlink requests with RTM_NEWTFILTER and NLM_F_CREATE
flag were allowed where the kernel would auto-generate a pref/prio.
We can piggyback on that and use prio of 0 as a wildcard for
requests of RTM_DELTFILTER.
For notifying tc netlink monitoring users (e.g. libnl uses this
for caching), there are two options, that is, sending individual
tfilter_notify() notifications for each tcf_proto, or sending a
single one indicating wildcard removal. I tried both and there
are pros and cons for each, eventually I decided for sending
individual tfilter_notify(), so that user space can support this
seamlessly and there won't be a mess of changing each and every
application to make sure expectations from the kernel won't break
when they don't understand single notification. Since linear chains
don't really scale, I expect only a handful of classifiers to be
attached at max for a given parent anyway.

Respect the stack's xmit_recursion limit for calls into dev_queue_xmit().
Currently, they are not handeled by the limiter when attached to clsact's
egress parent, for example, and a buggy program redirecting it to the
same device again could run into stack overflow eventually. It would be
good if we could notify an admin to give him a chance to react. We reuse
xmit_recursion instead of having one private to eBPF, so that the stack's
current recursion depth will be taken into account as well. Follow-up to

alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workqueue
mlxsw_wq is used for FDB notif. processing with workitems that are
involved in normal device operation && because it's a network device
which can be depended upon during memory reclaim.
Workitems &trans->timeout_dw and &mlxsw_sp->fdb_notify.dw,
map to mlxsw_sp_fdb_notify_work (processes FDB notifications from the
underlying device and resolves the netdev to which the entry points to
and notifies the bridge using the switchdev notifier) and
mlxsw_emad_trans_timeout_work (provides async EMAD register access)
respectively. They require forward progress under memory pressure and
hence, WQ_MEM_RECLAIM has been set.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.

alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem viz
(&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status)
is involved in a brief poll routine for checking transmit queue status
and is an intergral part of normal device operation.
WQ_MEM_RECLAIM has been set to guarantee forward progress under memory
pressure, which is a requirement here.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.
flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty.

Socket option PACKET_FANOUT_DATA takes a struct sock_fprog as argument
if PACKET_FANOUT has mode PACKET_FANOUT_CBPF. This structure contains
a pointer into user memory. If userland is 32-bit and kernel is 64-bit
the two disagree about the layout of struct sock_fprog.
Add compat setsockopt support to convert a 32-bit compat_sock_fprog to
a 64-bit sock_fprog. This is analogous to compat_sock_fprog support for
SO_REUSEPORT added in commit 1957598840 ("soreuseport: add compat
case for setsockopt SO_ATTACH_REUSEPORT_CBPF").

mlx4 RSS is limited to spread incoming packets to a power of two number
of queues.
An uniformly distibuted traffic would be split on queues 0 to N-1, N
being a power of two, each queue having a 1/N weight.
If number of RX queues is not a power of two, upper RX queues do not
receive traffic.
ethtool -x is lying, because it pretends some queues have higher weight.
Before patch:
lpaa24:~# ethtool -L eth1 rx 24
lpaa24:~# ethtool -x eth1
RX flow hash indirection table for eth1 with 24 RX ring(s):
0: 0 1 2 3 4 5 6 7
8: 8 9 10 11 12 13 14 15
16: 0 1 2 3 4 5 6 7
RSS hash key:

If this information was correct, user space tools could expect queues 0
to 7 to receive twice more traffic than queues 8 to 15
After patch :

lpaa24:~# ethtool -x eth1

====================
net: bgmac: Misc improvements
This patch series add minor changes to the bgmac driver:
- properly bind net_device with its backing device structure such that
we can locate the device using common helper functions
- add support for ethtool statistics reading the HW MIB counters which
is useful for debugging
- add netdev statistics throughout the TX/RX path to know what is going on
