iput() ends up calling ->evict() on new inode, which is not yet initialized
by owning fs. So use destroy_inode() instead.
Add to sb->s_inodes list only if inode is not in I_CREATING state (meaning
that it wasn't allocated with new_inode(), which already does the
insertion).

These extended commands require their own dma memory areas for a header

The kernel provides a __packed definition to abstract away from the
compiler specific attributes tag.
Convert all packed structures in VSP1 to use it.
The GCC documentation [0] describes this attribute as "the structure or
union is placed to minimize the memory required".
The Keil compiler documentation at [1] warns that the use of this
attribute can cause a performance penalty in the event that the compiler
can not deduce the allignment of each field.
Careful examination of the object code generated both with and without
this attribute shows that these structures are accessed identically and
are not affected by any performance penalty. The structures are
correctly aligned and padded to match the needs of the hardware already.
This patch does not serve to make a decision as to the use of the
attribute, but purely to clean up the code to use the kernel defined
abstraction as per [2].

We don't want open-by-handle picking half-set-up in-core
struct inode from e.g. mkdir() having failed halfway through.
In other words, we don't want such inodes returned by iget_locked()
on their way to extinction. However, we can't just have them
unhashed - otherwise open-by-handle immediately *after* that would've
ended up creating a new in-core inode over the on-disk one that
is in process of being freed right under us.
Solution: new flag (I_CREATING) set by insert_inode_locked() and
removed by unlock_new_inode() and a new primitive (discard_new_inode())
to be used by such halfway-through-setup failure exits instead of
unlock_new_inode() / iput() combinations. That primitive unlocks new
inode, but leaves I_CREATING in place.
iget_locked() treats finding an I_CREATING inode as failure
(-ESTALE, once we sort out the error propagation).
insert_inode_locked() treats the same as instant -EBUSY.
ilookup() treats those as icache miss.

mlxsw: Fix ACL actions error condition handling
Nir says:
Two issues were lately noticed within mlxsw ACL actions error condition
handling. The first patch deals with conflicting actions such as:
# tc filter add dev swp49 parent ffff: \
protocol ip pref 10 flower skip_sw dst_ip 192.168.101.1 \
action goto chain 100 \
action mirred egress redirect dev swp4
The second action will never execute, however SW model allows this
configuration, while the mlxsw driver cannot allow for it as it
implements actions in sets of up to three actions per set with a single
termination marking. Conflicting actions create a contradiction over
this single marking and thus cannot be configured. The fix replaces a
misplaced warning with an error code to be returned.
Patches 2-4 fix a condition of duplicate destruction of resources. Some
actions require allocation of specific resource prior to setting the
action itself. On error condition this resource was destroyed twice,
leading to a crash when using mirror action, and to a redundant
destruction in other cases, since for error condition rule destruction
also takes care of resource destruction. In order to fix this state a
symmetry in behavior is added and resource destruction also takes care
of removing the resource from rule's resource list.

In previous patch mlxsw_afa_resource_del() was added to avoid a duplicate
resource detruction scenario.
For mirror actions, such duplicate destruction leads to a crash as in:
# tc qdisc add dev swp49 ingress
# tc filter add dev swp49 parent ffff: \
protocol ip chain 100 pref 10 \
flower skip_sw dst_ip 192.168.101.1 action drop
# tc filter add dev swp49 parent ffff: \
protocol ip pref 10 \
flower skip_sw dst_ip 192.168.101.1 action goto chain 100 \
action mirred egress mirror dev swp4
Therefore add a call to mlxsw_afa_resource_del() in
mlxsw_afa_mirror_destroy() in order to clear that resource
from rule's resources.

Some ACL actions require the allocation of a separate resource
prior to applying the action itself. When facing an error condition
during the setup phase of the action, resource should be destroyed.
For such actions the destruction was done twice which is dangerous
and lead to a potential crash.
The destruction took place first upon error on action setup phase
and then as the rule was destroyed.
The following sequence generated a crash:
# tc qdisc add dev swp49 ingress
# tc filter add dev swp49 parent ffff: \
protocol ip chain 100 pref 10 \
flower skip_sw dst_ip 192.168.101.1 action drop
# tc filter add dev swp49 parent ffff: \
protocol ip pref 10 \
flower skip_sw dst_ip 192.168.101.1 action goto chain 100 \
action mirred egress mirror dev swp4
Therefore add mlxsw_afa_resource_del() as a complement of
mlxsw_afa_resource_add() to add symmetry to resource_list membership
handling. Call this from mlxsw_afa_fwd_entry_ref_destroy() to make the
_fwd_entry_ref_create() and _fwd_entry_ref_destroy() pair of calls a
NOP.

Spectrum switch ACL action set is built in groups of three actions
which may point to additional actions. A group holds a single record
which can be set as goto record for pointing at a following group
or can be set to mark the termination of the lookup. This is perfectly
adequate for handling a series of actions to be executed on a packet.
While the SW model allows configuration of conflicting actions
where it is clear that some actions will never execute, the mlxsw
driver must block such configurations as it creates a conflict
over the single terminate/goto record value.
For a conflicting actions configuration such as:
# tc filter add dev swp49 parent ffff: \
protocol ip pref 10 \
flower skip_sw dst_ip 192.168.101.1 \
action goto chain 100 \
action mirred egress mirror dev swp4
Where it is clear that the last action will never execute, the
mlxsw driver was issuing a warning instead of returning an error.
Therefore replace that warning with an error for this specific
case.

connection tracking zones currently depend on the xtables CT target.
The reasoning was that it makes no sense to support zones if they can't
be configured (which needed CT target).
Nowadays zones can also be used by OVS and configured via nftables,
so remove the dependency.
connection tracking labels are handled via hidden dependency that gets
auto-selected by the connlabel match.
Make it a visible knob, as labels can be attached via ctnetlink
or via nftables rules (nft_ct expression) too.
This allows to use conntrack labels and zones with nftables-only build.
