Change the ports[DSA_MAX_PORTS] array of the dsa_switch structure for a
zero-length array, allocated at the same time as the dsa_switch
structure itself. A dsa_switch_alloc() helper is provided for that.
This commit brings no functional change yet since we pass DSA_MAX_PORTS
as the number of ports for the moment. Future patches can update the DSA
drivers separately to support dynamic number of ports.

====================
ravb: Support 1Gbps on R-Car H3 ES1.1+ and R-Car M3-W
this series adds support for gigabit communication to the Renesas
EthernetAVB controller when used in conjunction with R-Car Gen3 H3
ES1.1+ and M3-W SoCs. Gigabit is already supported with R-Car Gen 2
SoCs.
The patch from Geert was previously posted for inclusion in v4.10 and
acked by Dave for that purpose. It was, however, not accepted by the
ARM SoC maintainers.
The path from Mizuguchi-san is to address timing problems observed
with gigabit transfers. I would like it considered although my own
testing on M3-W did not show any timing problems.
Changes since v1:
* Address various feedback for "APSR" patch as noted in its changelog
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The limitation to 10/100Mbit speeds on R-Car Gen3 is valid for R-Car H3
ES1.0 only. Check for the exact SoC model to allow 1Gbps on newer
revisions of R-Car H3, and on R-Car M3-W.

This patch enables tx and rx clock internal delay modes (TDM and RDM).
This is to address a failure in the case of 1Gbps communication using the
by salvator-x board with the KSZ9031RNX phy. This has been reported to
occur with both the r8a7795 (H3) and r8a7796 (M3-W) SoCs.
With this change APSR internal delay modes are enabled for
"rgmii-id", "rgmii-rxid" and "rgmii-txid" phy modes as follows:
phy mode | ASPR delay mode

rgmii-id | TDM and RDM
rgmii-rxid | RDM

Quotacheck runs at mount time in situations where quota accounting must
be recalculated. In doing so, it uses bulkstat to visit every inode in
the filesystem. Historically, every inode processed during quotacheck
was released and immediately tagged for reclaim because quotacheck runs
before the superblock is marked active by the VFS. In other words,
the final iput() lead to an immediate ->destroy_inode() call, which
allowed the XFS background reclaim worker to start reclaiming inodes.
Commit 17c12bcd3 ("xfs: when replaying bmap operations, don't let
unlinked inodes get reaped") marks the XFS superblock active sooner as
part of the mount process to support caching inodes processed during log
recovery. This occurs before quotacheck and thus means all inodes
processed by quotacheck are inserted to the LRU on release. The
s_umount lock is held until the mount has completed and thus prevents
the shrinkers from operating on the sb. This means that quotacheck can
excessively populate the inode LRU and lead to OOM conditions on systems
without sufficient RAM.
Update the quotacheck bulkstat handler to set XFS_IGET_DONTCACHE on
inodes processed by quotacheck. This causes ->drop_inode() to return 1
and in turn causes iput_final() to evict the inode. This preserves the
original quotacheck behavior and prevents it from overloading the LRU
and running out of memory.

Slava Shwartsman reported a warning in skb_try_coalesce(), when we
detect skb->truesize is completely wrong.
In his case, issue came from IPv6 reassembly coping with malicious
datagrams, that forced various pskb_may_pull() to reallocate a bigger
skb->head than the one allocated by NIC driver before entering GRO
layer.
Current code does not change skb->truesize, leaving this burden to
callers if they care enough.
Blindly changing skb->truesize in pskb_expand_head() is not
easy, as some producers might track skb->truesize, for example
in xmit path for back pressure feedback (sk->sk_wmem_alloc)
We can detect the cases where it should be safe to change
skb->truesize :
1) skb is not attached to a socket.
2) If it is attached to a socket, destructor is sock_edemux()
My audit gave only two callers doing their own skb->truesize

I had to remove skb parameter in sock_edemux macro when
CONFIG_INET is not set to avoid a compile error.

sfc: encapsulated filters
This series adds support for setting up filters for encapsulated traffic on
SFC 8000-series adapters, which recognise VXLAN, GENEVE and NVGRE packets by
parsing packet headers. (VXLAN and GENEVE will only be recognised if the
driver on the primary PF has notified the firmware of relevant UDP ports,
which this driver does not yet do.)
While the driver currently has no way of using these filters for flow
steering, it is nonetheless necessary to insert catch-all (aka 'default')
filters to direct this traffic, similar to the existing unencapsulated uni-
and multi-cast catch-all filters, as otherwise the traffic will be dropped
by the NIC - implementation details of the hardware filtering mean that the
traffic will not get matched on outer MAC address to unencapsulated catch-
all filters. (Yes, this is a mess.)
Although this is, therefore, fixing a bug in the existing driver, it's a bug
which has existed since 8000 series support was added, and the fix involves
quite a big patch with an 'adding features' flavour to it, hence why this is
for net-next rather than net and stable.
v2: move netif_cond_dbg into netdevice.h and its own patch
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
8000 series adapters support filtering VXLAN, NVGRE and GENEVE traffic
based on inner fields, and when the NIC recognises such traffic, it
does not match unencapsulated traffic filters any more. So add catch-
all filters for encapsulated traffic on supporting platforms.
Although recognition of VXLAN and GENEVE is based on UDP ports, and thus
will not occur until the driver (on the primary PF) notifies the
firmware of UDP ports to use, NVGRE will always be recognised, hence
without this patch 8000 series adapters will drop all NVGRE traffic.

If the NIC is switched from full-featured to low-latency, encapsulated
filters are no longer available, and this causes errors. This patch
removes those filters from the filter table on restore.
Also, if filters which are removed by the above, or which we fail to
insert when restoring filters, were UC, MC or broadcast default
filters, invalidate the corresponding vlan->default_filters entry.

various gtp fixes
I'm sorry for the compile error mess up in the last version.
It's no excuse for not test compiling, but the hunks got lost in
a rebase.
This is the part of the previous "simple gtp improvements" series
that Pablo indicated should go into net.
The addition of the module alias fixes genl family autoloading,
clearing the DF bit fixes a protocol violation in regard to the
specification and the netns comparison fixes a corner case of
cross netns recv.

The use of the passed through netlink src_net to check for a
cross netns operation was wrong. Using the GTP socket and the
GTP netdevice is always correct (even if the netdev has been
moved to new netns after link creation).

Unlike ipv4, this control socket is shared by all cpus so we cannot use
it as scratchpad area to annotate the mark that we pass to ip6_xmit().
Add a new parameter to ip6_xmit() to indicate the mark. The SCTP socket
family caches the flowi6 structure in the sctp_transport structure, so
we cannot use to carry the mark unless we later on reset it back, which
I discarded since it looks ugly to me.

Resuming from RPM can happen while already holding
dev->mode_config.mutex. This means we can't actually handle fbcon in
any RPM resume workers, since restoring fbcon requires grabbing
dev->mode_config.mutex again. So move the fbcon suspend/resume code into
it's own worker, and rely on that instead to avoid deadlocking.
This fixes more deadlocks for runtime suspending the GPU on the ThinkPad
W541. Reproduction recipe:
- Get a machine with both optimus and a nvidia card with connectors
attached to it
- Wait for the nvidia GPU to suspend
- Attempt to manually reprobe any of the connectors on the nvidia GPU
using sysfs
- *deadlock*
