====================
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.
3caa4af834 ("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 patch fdb8e12cc2cc ("netfilter: ipset: fix performance regression
in swap operation") missed to add the calls to gc cancellations
at the error path of create operations and at module unload. Also,
because the half of the destroy operations now executed by a
function registered by call_rcu(), neither NFNL_SUBSYS_IPSET mutex
or rcu read lock is held and therefore the checking of them results
false warnings.

'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.
The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior
Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Previously we would call apply_ctx_to_hw to enable and disable
phantom pipes. However, apply_ctx_to_hw can potentially update
non-phantom pipes as well which is undesired. Instead of calling
apply_ctx_to_hw as a whole, call the relevant helpers for each
phantom pipe when enabling / disabling which will avoid us modifying
hardware state for non-phantom pipes unknowingly.
The use case is for an FRL display where FRL_Update is requested
by the display. In this case link_state_valid flag is cleared in
a passive callback thread and should be handled in the next stream /
link update. However, due to the call to apply_ctx_to_hw for the
phantom pipes during a flip, the main pipes were modified outside
of the desired sequence (driver does not handle link_state_valid = 0
on flips).

[Why]
To match firmware measurements and avoid hanging when accessing HW
that's in idle.
[How]
Increase the delays to what we've measured.

In the suspend abort cases, the gfx power rail doesn't turn off so
some GFXDEC registers/CSB can't reset to default value and at this
moment reinitialize GFXDEC/CSB will result in an unexpected error.
So let skip those program sequence for the suspend abort case.

[why]
When populating dml pipes, odm combine policy should be assigned based
on the pipe topology of the context passed in. DML pipes could be
repopulated multiple times during single validate bandwidth attempt. We
need to make sure that whenever we repopulate the dml pipes it is always
aligned with the updated context. There is a case where DML pipes get
repopulated during FPO optimization after ODM combine policy is changed.
Since in the current code we reinitlaize ODM combine policy, even though
the current context has ODM combine enabled, we overwrite it despite the
pipes are already split. This causes DML to think that MPC combine is
used so we mistakenly enable MPC combine because we apply pipe split
with ODM combine policy reset. This issue doesn't impact non windowed
MPO with ODM case because the legacy policy has restricted use cases. We
don't encounter the case where both ODM and FPO optimizations are
enabled together. So we decide to leave it as is because it is about to
be replaced anyway.
