net: mvpp2: improve the mac address retrieval logic
This series aims at fixing the logic behind the MAC address retrieval in the

when the address given in the device tree isn't valid.
Thanks!

When using a mac address described in the device tree, a check is made
to see if it is valid. When it's not, no fallback is defined. This
patches tries to get the mac address from h/w (or use a random one if
the h/w one isn't valid) when the dt mac address isn't valid.

The MAC retrieval logic is using a variable to store an h/w stored mac
address and checks this mac against invalid ones before using it. But
the mac address is only read from h/w when using PPv2.1. So when using
PPv2.2 it defaults to its init state.
This patches fixes the logic to only check if the h/w mac is valid when
actually retrieving a mac from h/w.

Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree. Basically, updates to the conntrack core, enhancements for
nf_tables, conversion of netfilter hooks from linked list to array to
improve memory locality and asorted improvements for the Netfilter
codebase. More specifically, they are:
1) Add expection to hashes after timer initialization to prevent
access from another CPU that walks on the hashes and calls
del_timer(), from Florian Westphal.
2) Don't update nf_tables chain counters from hot path, this is only
used by the x_tables compatibility layer.
3) Get rid of nested rcu_read_lock() calls from netfilter hook path.
Hooks are always guaranteed to run from rcu read side, so remove
nested rcu_read_lock() where possible. Patch from Taehee Yoo.
4) nf_tables new ruleset generation notifications include PID and name
of the process that has updated the ruleset, from Phil Sutter.
5) Use skb_header_pointer() from nft_fib, so we can reuse this code from
the nf_family netdev family. Patch from Pablo M. Bermudo.
6) Add support for nft_fib in nf_tables netdev family, also from Pablo.
7) Use deferrable workqueue for conntrack garbage collection, to reduce
power consumption, from Patch from Subash Abhinov Kasiviswanathan.
8) Add nf_ct_expect_iterate_net() helper and use it. From Florian
Westphal.
9) Call nf_ct_unconfirmed_destroy only from cttimeout, from Florian.
10) Drop references on conntrack removal path when skbuffs has escaped via
nfqueue, from Florian.
11) Don't queue packets to nfqueue with dying conntrack, from Florian.
12) Constify nf_hook_ops structure, from Florian.
13) Remove neededlessly branch in nf_tables trace code, from Phil Sutter.
14) Add nla_strdup(), from Phil Sutter.
15) Rise nf_tables objects name size up to 255 chars, people want to use
DNS names, so increase this according to what RFC 1035 specifies.
Patch series from Phil Sutter.
16) Kill nf_conntrack_default_on, it's broken. Default on conntrack hook
registration on demand, suggested by Eric Dumazet, patch from Florian.
17) Remove unused variables in compat_copy_entry_from_user both in
ip_tables and arp_tables code. Patch from Taehee Yoo.
18) Constify struct nf_conntrack_l4proto, from Julia Lawall.
19) Constify nf_loginfo structure, also from Julia.
20) Use a single rb root in connlimit, from Taehee Yoo.
21) Remove unused netfilter_queue_init() prototype, from Taehee Yoo.
22) Use audit_log() instead of open-coding it, from Geliang Tang.
23) Allow to mangle tcp options via nft_exthdr, from Florian.
24) Allow to fetch TCP MSS from nft_rt, from Florian. This includes
a fix for a miscalculation of the minimal length.
25) Simplify branch logic in h323 helper, from Nick Desaulniers.

27) Remove protocol name field from nf_conntrack_{l3,l4}proto structure.

31) Constify most nf_conntrack_{l3,l4}proto helper functions, from
Florian.
32) Fix broken indentation in ebtables extensions, from Colin Ian King.
33) Fix several harmless sparse warning, from Florian.
34) Convert netfilter hook infrastructure to use array for better memory
locality, joint work done by Florian and Aaron Conole. Moreover, add
some instrumentation to debug this.
35) Batch nf_unregister_net_hooks() calls, to call synchronize_net once
per batch, from Florian.

Instead of tracking wmem_queued and sk_mem_charge by incrementing
in the verdict SK_REDIRECT paths and decrementing in the tx work
path use skb_set_owner_w and sock_writeable helpers. This solves
a few issues with the current code. First, in SK_REDIRECT inc on
sk_wmem_queued and sk_mem_charge were being done without the peers
sock lock being held. Under stress this can result in accounting
errors when tx work and/or multiple verdict decisions are working
on the peer psock.
Additionally, this cleans up the code because we can rely on the
default destructor to decrement memory accounting on kfree_skb. Also
this will trigger sk_write_space when space becomes available on
kfree_skb() which wasn't happening before and prevent __sk_free
from being called until all in-flight packets are completed.

inet_diag: report TCP MD5 signing keys and addresses
Allow userspace to retrieve MD5 signature keys and addresses configured
on TCP sockets through inet_diag.
Thanks to Eric Dumazet and Stephen Hemminger for their useful
explanations and feedback.
v5: - memset the whole netlink payload after it has been nla_reserve-d
in tcp_diag_put_md5sig (a third memset had to be added for
tcpm_key so we might as well have just one for entire region).
- move the nla_total_size call from inet_sk_attr_size to the
idiag_get_aux_size defined by protocols as they could add multiple
netlink attributes,
- add check for net_admin in tcp_diag_get_aux_size.
v4: - add new struct tcp_diag_md5sig to report the data instead of
tcp_md5sig to avoid wasting 112 bytes on every tcpm_addr,
- memset tcpm_addr on IPv4 addresses to avoid leaks,
- style fix in inet_diag_dump_one_icsk.
v3: - rename inet_diag_*md5sig in tcp_diag.c to tcp_diag_* for
consistency,
- don't lock the socket in tcp_diag_put_md5sig,
- add checks on md5sig_count in tcp_diag_put_md5sig to not create
the netlink attribute if the list is empty, and to avoid overflows
or memory leaks if the list has changed in the meantime.
v2: - move changes to tcp_diag.c and extend inet_diag_handler to allow
protocols to provide additional data on INET_DIAG_INFO,
- lock socket before calling tcp_diag_put_md5sig.

The msg_zerocopy test defines SO_ZEROCOPY if necessary, but its value
is inconsistent with the one in asm-generic.h. Correct that.
Also convert one error to a warning. When the test is complete, report
throughput and close cleanly even if the process did not wait for all
completions.

Documentation for this feature was missing from the patchset.
Copied a lot from the netdev 2.1 paper, addressing some small
interface changes since then.
Changes
v1 -> v2
- change email discussion URL format
- clarify that u32 counter is per-syscall, unsigned and
wraps after UINT_MAX calls
- describe errno on send failure specific to MSG_ZEROCOPY
- a few very minor rewordings

Three regression fixes that should be addressed before the final
release: a missing mutex call in OSS PCM emulation ioctl, ASoC rt5670
headset detection breakage, and a regression in simple-card parser
code.
