mlxsw: Prepare for VLAN-aware bridge w/VxLAN
The driver is using 802.1Q filtering identifiers (FIDs) to represent the
different VLANs in the VLAN-aware bridge (only one is supported).
However, the device cannot assign a VNI to such FIDs, which prevents the
driver from supporting the enslavement of VxLAN devices to the
VLAN-aware bridge.
This patchset works around this limitation by emulating 802.1Q FIDs
using 802.1D FIDs, which can be assigned a VNI and so far have only been
used in conjunction with VLAN-unaware bridges.
The downside of this approach is that multiple {Port,VID}->FID entries
are required, whereas a single VID->FID entry is required with "true"
802.1Q FIDs.
First four patches introduce the new FID family of emulated 802.1Q FIDs
and the associated type of router interfaces (RIFs). Last patch flips
the driver to use this new FID family.
The diff is relatively small because the internal implementation of each
FID family is contained and hidden in spectrum_fid.c. Different internal
users (e.g., bridge, router) are aware of the different FID types, but
do not care about their internal implementation. This makes it trivial
to swap the current implementation of 802.1Q FIDs with the new one,
using 802.1D FIDs.

Replace 802.1Q FIDs and VLAN RIFs with their emulated counterparts.
The emulated 802.1Q FIDs are actually 802.1D FIDs and thus use the same
flood tables, of per-FID type. Therefore, add 4K-1 entries to the
per-FID flood tables for the new FIDs and get rid of the FID-offset
flood tables that were used by the old 802.1Q FIDs.

Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of
"VLAN" type, whereas RIFs constructed on top of VLAN-unaware bridges of
"FID" type.
In other words, the RIF type is derived from the underlying FID type.
VLAN RIFs are used on top of 802.1Q FIDs, whereas FID RIFs are used on
top of 802.1D FIDs.
Since the previous patch emulated 802.1Q FIDs using 802.1D FIDs, this
patch emulates VLAN RIFs using FID RIFs.

The driver uses 802.1Q FIDs when offloading a VLAN-aware bridge.
Unfortunately, it is not possible to assign a VNI to such FIDs, which
prompts the driver to forbid the enslavement of VxLAN devices to a
VLAN-aware bridge.
Workaround this hardware limitation by creating a new family of FIDs,
emulated 802.1Q FIDs. These FIDs are emulated using 802.1D FIDs, which
can be assigned a VNI.
The downside of this approach is that multiple {Port, VID}->FID entries
are required, whereas only a single VID->FID is required with "true"
802.1Q FIDs.

802.1D FIDs use a per-FID flood table, where the flood index into the
table is calculated by subtracting 4K from the FID's index.
Currently, 802.1D FIDs start at 4K, so the calculation is correct, but
if it was ever to change, the calculation will no longer be correct.
In addition, this change will allow us to reuse the flood index
calculation function in the next patch, where we are going to emulate
802.1Q FIDs using 802.1D FIDs.

net: bridge: add an option to disabe linklocal learning
This set adds a new bridge option which can control learning from
link-local packets, by default learning is on to be consistent and avoid
breaking users expectations. If the new no_linklocal_learn option is
enabled then the bridge will stop learning from link-local packets.
In order to save space for future boolean options, patch 01 adds a new
bool option API that uses a bitmask to control boolean options. The
bridge is by far the largest netlink attr user and we keep adding simple
boolean options which waste nl attr ids and space. We're not directly
mapping these to the in-kernel bridge flags because some might require
more complex configuration changes (e.g. if we were to add the per port
vlan stats now, it'd require multiple checks before changing value).
Any new bool option needs to be handled by both br_boolopt_toggle and get
in order to be able to retrieve its state later. All such options are
automatically exported via netlink. The behaviour of setting such
options is consistent with netlink option handling when a missing
option is being set (silently ignored), e.g. when a newer iproute2 is used
on older kernel. All supported options are exported via bm's optmask
when dumping the new attribute.
v2: address Andrew Lunn's comments, squash a minor change into patch 01,
export all supported options via optmask when dumping, add patch 03,
pass down extack so options can return meaningful errors, add
WARN_ON on unsupported options (should not happen)

We have been adding many new bridge options, a big number of which are
boolean but still take up netlink attribute ids and waste space in the skb.
Recently we discussed learning from link-local packets[1] and decided
yet another new boolean option will be needed, thus introducing this API
to save some bridge nl space.
The API supports changing the value of multiple boolean options at once
via the br_boolopt_multi struct which has an optmask (which options to
set, bit per opt) and optval (options' new values). Future boolean
options will only be added to the br_boolopt_id enum and then will have
to be handled in br_boolopt_toggle/get. The API will automatically
add the ability to change and export them via netlink, sysfs can use the
single boolopt function versions to do the same. The behaviour with
failing/succeeding is the same as with normal netlink option changing.
If an option requires mapping to internal kernel flag or needs special
configuration to be enabled then it should be handled in
br_boolopt_toggle. It should also be able to retrieve an option's current
state via br_boolopt_get.
v2: WARN_ON() on unsupported option as that shouldn't be possible and
also will help catch people who add new options without handling
them for both set and get. Pass down extack so if an option desires
it could set it on error and be more user-friendly.

A recent change added a null check on p->dev after p->dev was being
dereferenced by the ns_capable check on p->dev. It turns out that
neither the p->dev and p->br null checks are necessary, and can be
removed, which cleans up a static analyis warning.
As Nikolay Aleksandrov noted, these checks can be removed because:
"My reasoning of why it shouldn't be possible:
- On port add new_nbp() sets both p->dev and p->br before creating
kobj/sysfs
- On port del (trickier) del_nbp() calls kobject_del() before call_rcu()
to destroy the port which in turn calls sysfs_remove_dir() which uses
kernfs_remove() which deactivates (shouldn't be able to open new
files) and calls kernfs_drain() to drain current open/mmaped files in
the respective dir before continuing, thus making it impossible to
open a bridge port sysfs file with p->dev and p->br equal to NULL.
So I think it's safe to remove those checks altogether. It'd be nice to
get a second look over my reasoning as I might be missing something in
sysfs/kernfs call path."
Thanks to Nikolay Aleksandrov's suggestion to remove the check and
David Miller for sanity checking this.

Packet sockets with PACKET_TX_RING send skbs with user data in frags.
Before commit 5cd8d46ea1 ("packet: copy user buffers before orphan

a process to overwrite data still in flight.
This test opens two packet sockets, one to send and one to read.
The sender has a tx ring of one slot. It sends two packets with
different payload, then reads both and verifies their payload.
Before the above commit, both receive calls return the same data as
the send calls use the same buffer. From the commit, the clone
needed for looping onto a packet socket triggers an skb_copy_ubufs

Pull xfs fixes from Darrick Wong:
"Dave and I have continued our work fixing corruption problems that can
be found when running long-term burn-in exercisers on xfs. Here are
some patches fixing most of the problems, but there will likely be
more. :/
- Numerous corruption fixes for copy on write
- Numerous corruption fixes for blocksize < pagesize writes
- Don't miscalculate AG reservations for small final AGs
- Fix page cache truncation to work properly for reflink and extent
shifting
- Fix use-after-free when retrying failed inode/dquot buffer logging
- Fix corruptions seen when using copy_file_range in directio mode"
* tag 'xfs-4.20-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
iomap: readpages doesn't zero page tail beyond EOF
vfs: vfs_dedupe_file_range() doesn't return EOPNOTSUPP
iomap: dio data corruption and spurious errors when pipes fill
iomap: sub-block dio needs to zeroout beyond EOF
iomap: FUA is wrong for DIO O_DSYNC writes into unwritten extents
xfs: delalloc -> unwritten COW fork allocation can go wrong
xfs: flush removing page cache in xfs_reflink_remap_prep
xfs: extent shifting doesn't fully invalidate page cache
xfs: finobt AG reserves don't consider last AG can be a runt
xfs: fix transient reference count error in xfs_buf_resubmit_failed_buffers
xfs: uncached buffer tracing needs to print bno
xfs: make xfs_file_remap_range() static
xfs: fix shared extent data corruption due to missing cow reservation
The TX stats should be started with the tx_stats_syncp,
there seems to be a copy/paste error in the driver.

The vsc85xx_default_config function called in the vsc85xx_config_init
function which is used by VSC8530, VSC8531, VSC8540 and VSC8541 PHYs
mistakenly calls phy_read and phy_write in-between phy_select_page and
phy_restore_page.
phy_select_page and phy_restore_page actually take and release the MDIO
bus lock and phy_write and phy_read take and release the lock to write
or read to a PHY register.
Let's fix this deadlock by using phy_modify_paged which handles
correctly a read followed by a write in a non-standard page.
Fixes: 6a0bfbbe20 ("net: phy: mscc: migrate to phy_select/restore_page functions")

The correct form is "can be probed", so fix the typo.
