====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Narrow down target/match revision to u8 in nft_compat.

2) Bail out with unused flags in nft_compat.

3) Restrict layer 4 protocol to u16 in nft_compat.

4) Remove static in pipapo get command that slipped through when
   reducing set memory footprint.

5) Follow up incremental fix for the ipset performance regression,
   this includes the missing gc cancellation, from Jozsef Kadlecsik.

6) Allow to filter by zone 0 in ctnetlink, do not interpret zone 0
   as no filtering, from Felix Huettner.

7) Reject direction for NFT_CT_ID.

8) Use timestamp to check for set element expiration while transaction
   is handled to prevent garbage collection from removing set elements
   that were just added by this transaction. Packet path and netlink
   dump/get path still use current time to check for expiration.

9) Restore NF_REPEAT in nfnetlink_queue, from Florian Westphal.

10) map_index needs to be percpu and per-set, not just percpu.
    At this time its possible for a pipapo set to fill the all-zero part
    with ones and take the 'might have bits set' as 'start-from-zero' area.
    From Florian Westphal. This includes three patches:

    - Change scratchpad area to a structure that provides space for a
      per-set-and-cpu toggle and uses it of the percpu one.

    - Add a new free helper to prepare for the next patch.

    - Remove the scratch_aligned pointer and makes AVX2 implementation
      use the exact same memory addresses for read/store of the matching
      state.

use ->scratch for both avx2 and the generic implementation.

After previous change the scratch->map member is always aligned properly
for AVX2, so we can just use scratch->map in AVX2 too.

The alignoff delta is stored in the scratchpad so we can reconstruct
the correct address to free the area again.

Pipapo needs a scratchpad area to keep state during matching.
This state can be large and thus cannot reside on stack.

Each set preallocates percpu areas for this.

On each match stage, one scratchpad half starts with all-zero and the other
is inited to all-ones.

At the end of each stage, the half that starts with all-ones is
always zero.  Before next field is tested, pointers to the two halves
are swapped, i.e.  resmap pointer turns into fill pointer and vice versa.

After the last field has been processed, pipapo stashes the
index toggle in a percpu variable, with assumption that next packet
will start with the all-zero half and sets all bits in the other to 1.

This isn't reliable.

There can be multiple sets and we can't be sure that the upper
and lower half of all set scratch map is always in sync (lookups
can be conditional), so one set might have swapped, but other might
not have been queried.

Thus we need to keep the index per-set-and-cpu, just like the
scratchpad.

Note that this bug fix is incomplete, there is a related issue.

avx2 and normal implementation might use slightly different areas of the
map array space due to the avx2 alignment requirements, so
m->scratch (generic/fallback implementation) and ->scratch_aligned
(avx) may partially overlap. scratch and scratch_aligned are not distinct
objects, the latter is just the aligned address of the former.

After this change, write to scratch_align->map_index may write to
scratch->map, so this issue becomes more prominent, we can set to 1
a bit in the supposedly-all-zero area of scratch->map[].

A followup patch will remove the scratch_aligned and makes generic and
avx code use the same (aligned) area.

Its done in a separate change to ease review.

Add a timestamp field at the beginning of the transaction, store it
in the nftables per-netns area.

Update set backend .insert, .deactivate and sync gc path to use the
timestamp, this avoids that an element expires while control plane
transaction is still unfinished.

.lookup and .update, which are used from packet path, still use the
current time to check if the element has expired. And .get path and dump
also since this runs lockless under rcu read size lock. Then, there is
async gc which also needs to check the current time since it runs
asynchronously from a workqueue.

Symptom:
In case of a bad cable connection (e.g. dirty optics) a fast sequence of
network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth
interface. In case of a second DOWN while recovery is still ongoing, it
can happen that the IP@ of a Layer3 qeth interface is lost and will not
be recovered by the second UP.

Problem:
When registration of IP addresses with Layer 3 qeth devices fails, (e.g.
because of bad address format) the respective IP address is deleted from
its hash-table in the driver. If registration fails because of a ENETDOWN
condition, the address should stay in the hashtable, so a subsequent
recovery can restore it.

3caa4af8 ("qeth: keep ip-address after LAN_OFFLINE failure")
fixes this for registration failures during normal operation, but not
during recovery.

Solution:
Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For
consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE,
i.e. for some reason the card already/still has this address registered.

The below commit  introduced a WARN when phy state is not in the states:
PHY_HALTED, PHY_READY and PHY_UP.
commit 744d23c7 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state")

When cpsw_new resumes, there have port in PHY_NOLINK state, so the below
warning comes out. Set mac_managed_pm be true to tell mdio that the phy
resume/suspend is managed by the mac, to fix the following warning:

Since commit 48e1b4d3 ("gpiolib: remove the GPIO device from the list
when it's unregistered") we remove the GPIO device entry from the global
list (used to order devices by their GPIO ranges) when unregistering the
chip, not when releasing the device. It will not happen when the last
reference is put anymore. This means, we need to remove it in error path
in gpiochip_add_data_with_key() unconditionally, without checking if the
device's .release() callback is set.

If GUP fails and we are in_kthread, we can have pinned = 0 and ret = 0.
If that happens we call sg_alloc_append_table_from_pages() with n_pages
= 0, which is not well behaved and can trigger:

kernel BUG at include/linux/scatterlist.h:115!

depending on if the pages array happens to be zeroed or not. Even if we
don't hit that it crashes later when trying to dma_map the returned
table.

The calculation to determine max page size of a VMA during a REMAP
operations assumes the VMA has been bound. This assumption is not true
if the VMA is from an eariler operation in an array of binds. If a VMA
has not been bound use the maximum page size which will ensure the
previous / next REMAP operations are not incorrectly skipped.

intel_power_domains_init is called twice in xe_device_probe:

   xe_device_probe()

2) intel_power_domains_init()
   intel_display_driver_probe_noirq()

   xe_device_probe()

It needs remove one to avoid power_domains->power_wells double malloc.

The call to intel_power_domains_cleanup() needs to stay where it is for
now. The main issue is that while the init is called by the display
side, shared by i915 and xe, the cleanup is called by a non-shared code
path. Fixing that will be done as a separate commit.

I found that rewriting the assignment using pointer addition rather than the
equivalent array index calculation prevents the warning, so use that instead.

I sent a bug report against gcc for the false positive warning.

A REMAP op is composed of 3 VMA's - unmap, prev map, and next map. When
op_execute fails with -EAGAIN we need to update the local VMA pointer to
the current op state and then repin the VMA if it is a userptr.

Fixes a failure seen in xe_vm.munmap-style-unbind-userptr-one-partial.
