The tile architecture already marks RO_DATA as read-only in
the kernel, so grouping RO_AFTER_INIT_DATA with RO_DATA, as is
done by default, means the kernel faults in init when it tries
to write to RO_AFTER_INIT_DATA. For now, just arrange that
__ro_after_init is handled like __write_once, i.e. __read_mostly.

Since commit b45f64d16d45 ("mlxsw: spectrum_router: Use FIB notifications
instead of switchdev calls") we reflect to the device the entire FIB
table and not only FIBs that point to netdevs created by the driver.
During module removal, FIBs of the second type are removed following
NETDEV_UNREGISTER events sent. The other FIBs are still present in both
the driver's cache and the device's table.
Fix this by iterating over all the FIB tables in the device and flush
them. There's no need to take locks, as we're the only writer.

Commit 52f95bbfcf72 ("stmmac: fix adjust link call in case of a switch
is attached") added some logic to avoid polling the fixed PHY and
therefore invoking the adjust_link callback more than once, since this
is a fixed PHY and link events won't be generated.
This works fine the first time, because we start with phydev->irq =
PHY_POLL, so we call adjust_link, then we set phydev->irq =
PHY_IGNORE_INTERRUPT and we stop polling the PHY.
Now, if we called ndo_close(), which calls both phy_stop() and does an
explicit netif_carrier_off(), we end up with a link down. Upon calling
ndo_open() again, despite starting the PHY state machine, we have
PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the
link is permanently down.

Now when users shutdown a sock with SEND_SHUTDOWN in sctp, even if
this sock has no connection (assoc), sk state would be changed to
SCTP_SS_CLOSING, which is not as we expect.
Besides, after that if users try to listen on this sock, kernel
could even panic when it dereference sctp_sk(sk)->bind_hash in
sctp_inet_listen, as bind_hash is null when sock has no assoc.
This patch is to move sk state change after checking sk assocs
is not empty, and also merge these two if() conditions and reduce
indent level.

bnx2: Wait for in-flight DMA to complete at probe stage
This is v2 post.
In commit 3e1be7a ("bnx2: Reset device during driver initialization"),
firmware requesting code was moved from open stage to probe stage.
The reason is in kdump kernel hardware iommu need device be reset in
driver probe stage, otherwise those in-flight DMA from 1st kernel
will continue going and look up into the newly created io-page tables.
However bnx2 chip resetting involves firmware requesting issue, that
need be done in open stage.
Michale Chan suggested we can just wait for the old in-flight DMA to
complete at probe stage, then though without device resetting, we
don't need to worry the old in-flight DMA could continue looking up
the newly created io-page tables.
v1->v2:
Michael suggested to wait for the in-flight DMA to complete at probe
stage. So give up the old method of trying to reset chip at probe
stage, take the new way accordingly.

This reverts commit 3e1be7ad2d38c6bd6aeef96df9bd0a7822f4e51c.
When people build bnx2 driver into kernel, it will fail to detect
and load firmware because firmware is contained in initramfs and
initramfs has not been uncompressed yet during do_initcalls. So
revert commit 3e1be7a and work out a new way in the later patch.

Similar to commit 14135f30e33c ("inet: fix sleeping inside inet_wait_for_connect()"),
sk_wait_event() needs to fix too, because release_sock() is blocking,
it changes the process state back to running after sleep, which breaks
the previous prepare_to_wait().
Switch to the new wait API.

In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data
usage") the stream specific information initialization was broken, with
the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.
Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc(). When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

This reverts commit bfd8d3f23b51018388be0411ccbc2d56277fe294.
It turns out that this flushes things much too aggressiverly, and causes
lines to break up when the system logger races with new continuation
lines being printed.
There's a pending patch to make printk() flushing much more
straightforward, but it's too invasive for 4.9, so in the meantime let's
just not make the system message logging flush continuation lines.
They'll be flushed by the final newline anyway.

Netfilter updates for net-next
The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.
Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:
nft add table netdev x
nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
nft add rule netdev x y drop
And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:
17.30% kpktgend_0 [nf_tables] [k] nft_do_chain
15.75% kpktgend_0 [kernel.vmlinux] [k] __netif_receive_skb_core
10.39% kpktgend_0 [nf_tables_netdev] [k] nft_do_chain_netdev
I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.
This rework contains more specifically, in strict order, these patches:
1) Remove compile-time debugging from core.
2) Remove obsolete comments that predate the rcu era. These days it is
well known that a Netfilter hook always runs under rcu_read_lock().
3) Remove threshold handling, this is only used by br_netfilter too.
We already have specific code to handle this from br_netfilter,
so remove this code from the core path.
4) Deprecate NF_STOP, as this is only used by br_netfilter.
5) Place nf_state_hook pointer into xt_action_param structure, so
this structure fits into one single cacheline according to pahole.
This also implicit affects nftables since it also relies on the
xt_action_param structure.
6) Move state->hook_entries into nf_queue entry. The hook_entries
pointer is only required by nf_queue(), so we can store this in the
queue entry instead.
7) use switch() statement to handle verdict cases.
8) Remove hook_entries field from nf_hook_state structure, this is only
required by nf_queue, so store it in nf_queue_entry structure.
9) Merge nf_iterate() into nf_hook_slow() that results in a much more
simple and readable function.
10) Handle NF_REPEAT away from the core, so far the only client is
nf_conntrack_in() and we can restart the packet processing using a
simple goto to jump back there when the TCP requires it.
This update required a second pass to fix fallout, fix from
Arnd Bergmann.
11) Set random seed from nft_hash when no seed is specified from
userspace.
12) Simplify nf_tables expression registration, in a much smarter way
to save lots of boiler plate code, by Liping Zhang.
13) Simplify layer 4 protocol conntrack tracker registration, from
Davide Caratti.
14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
to recent generalization of the socket infrastructure, from Arnd
Bergmann.
15) Then, the ipset batch from Jozsef, he describes it as it follows:
* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
because it is unnecessary to zero out the area just before
explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
across all set types.
* Count non-static extension memory into memsize calculation for
userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
by Muhammad Falak R Wani, individually for the set type families.
16) Remove useless connlabel field in struct netns_ct, patch from
Florian Westphal.
17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
{ip,ip6,arp}tables code that uses this.

The RGMII modes delays can be set via strapping pings or EEPROM.
Don't change them unless explicitly asked to change them. The recent
refactoring of setting the MAC configuration changed this behaviours,
in that CPU and DSA ports have any pre-configured RGMII delays
removed. This breaks the Armada 370RD board. Restore the previous
behaviour, in that RGMII delays are only applied/removed when
explicitly asked for via an phy-mode being PHY_INTERFACE_MODE_RGMII*

This is a static checker warning, not something I'm desperately
concerned about. But snprintf() returns the number of bytes that
would have been copied if there were space. We really care about the
number of bytes that actually were copied so we should use scnprintf()
instead.
It probably won't overrun, and in that case we may as well just use
sprintf() but these sorts of things make static checkers and code
reviewers happier.

passing in a constant which makes this timeout HZ dependent, so pass it
through msecs_to_jiffies() to fix this up.

Since commit 7926dbfa4bc1 ("netfilter: don't use
mutex_lock_interruptible()"), the function xt_find_table_lock can only
return NULL on an error. Simplify the call sites and update the
comment before the function.
The semantic patch that change the code is as follows:

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
The previous implementation of set_settings was modifying
the value of advertising, but with the new API, it's not
possible. The structure ethtool_link_ksettings is defined
as const.

efx_copy_channel() doesn't correctly clear the napi_hash related state.
This means that when napi_hash_add is called for that channel nothing is
done, and we are left with a copy of the napi_hash_node from the old
channel. When we later call napi_hash_del() on this channel we have a
stale napi_hash_node.
Corruption is only seen when there are multiple entries in one of the
napi_hash lists. This is made more likely by having a very large number
of channels. Testing was carried out with 512 channels - 32 channels on
each of 16 ports.
This failure typically appears as protection faults within napi_by_id()
or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring
sizes are changed (ethtool -G).

No need to stop ctlr if it was already stopped. It can cause timeout
warns. Steps:
- ifconfig eth0 down
- ethtool -l eth0 rx 8 tx 8
- ethtool -l eth0 rx 1 tx 1

The dma ctlr is reseted to 0 while cpdma soft reset, thus cpdma ctlr
cannot be configured after cpdma is stopped. So restoring content
of cpdma ctlr while off/on procedure is needed. The cpdma ctlr off/on
procedure is present while interface down/up and while changing number
of channels with ethtool. In order to not restore content in many
places, move it to cpdma_ctlr_start().
