This patch adds support for set flushing, that consists of walking over
the set elements if the NFTA_SET_ELEM_LIST_ELEMENTS attribute is set.
This patch requires the following changes:
1) Add set->ops->deactivate_one() operation: This allows us to
deactivate an element from the set element walk path, given we can
skip the lookup that happens in ->deactivate().
2) Add a new nft_trans_alloc_gfp() function since we need to allocate
transactions using GFP_ATOMIC given the set walk path happens with
held rcu_read_lock.

SCTP GSO and hardware can do CRC32c computation after netfilter processing,
so we can avoid calling sctp_compute_checksum() on skb if skb->ip_summed
is equal to CHECKSUM_PARTIAL. Moreover, set skb->ip_summed to CHECKSUM_NONE
when the NAT code computes the CRC, to prevent offloaders from computing
it again (on ixgbe this resulted in a transmission with wrong L4 checksum).

This patch allows us to refer to stateful object dictionaries, the
source register indicates the key data to be used to look up for the
corresponding state object. We can refer to these maps through names or,
alternatively, the map transaction id. This allows us to refer to both
anonymous and named maps.

This patch allows you to refer to stateful objects from set elements.
This provides the infrastructure to create maps where the right hand
side of the mapping is a stateful object.
This allows us to build dictionaries of stateful objects, that you can
use to perform fast lookups using any arbitrary key combination.

Algorithms not compatible with mcryptd could be spawned by mcryptd
with a direct crypto_alloc_tfm invocation using a "mcryptd(alg)" name
construct. This causes mcryptd to crash the kernel if an arbitrary
"alg" is incompatible and not intended to be used with mcryptd. It is
an issue if AF_ALG tries to spawn mcryptd(alg) to expose it externally.
But such algorithms must be used internally and not be exposed.
We added a check to enforce that only internal algorithms are allowed
with mcryptd at the time mcryptd is spawning an algorithm.

For encryption, the AEAD ciphers require AAD || PT as input and generate
AAD || CT || Tag as output and vice versa for decryption. Prior to this
patch, the AF_ALG interface for AEAD ciphers requires the buffer to be
present as input for encryption. Similarly, the output buffer for
decryption required the presence of the tag buffer too. This implies
that the kernel reads / writes data buffers from/to kernel space
even though this operation is not required.
This patch changes the AF_ALG AEAD interface to be consistent with the
in-kernel AEAD cipher requirements.
Due to this handling, he changes are transparent to user space with one
exception: the return code of recv indicates the mount of output buffer.
That output buffer has a different size compared to before the patch
which implies that the return code of recv will also be different.
For example, a decryption operation uses 16 bytes AAD, 16 bytes CT and
16 bytes tag, the AF_ALG AEAD interface before showed a recv return
code of 48 (bytes) whereas after this patch, the return code is 32
since the tag is not returned any more.

mv_cesa_hash_std_step() copies the creq->state into the SRAM at each

I have been having a lot of unexplainable crashes in osc_lru_shrink
lately that I could not see a good explanation for and then I found
this patch that slip under the radar somehow that incorrectly
converted while loop for lru list iteration into
list_for_each_entry_safe totally ignoring that in the body of
the loop we drop spinlocks guarding this list and move list entries
around.
Not sure why it was not showing up right away, perhaps some of the
more recent LRU changes committed caused some extra pressure on this
code that finally highlighted the breakage.

flush_icache_page_asm
We have four routines in pacache.S that use temporary alias pages:
copy_user_page_asm(), clear_user_page_asm(), flush_dcache_page_asm() and
flush_icache_page_asm(). copy_user_page_asm() and clear_user_page_asm()
don't purge the TLB entry used for the operation.
flush_dcache_page_asm() and flush_icache_page_asm do purge the entry.
Presumably, this was thought to optimize TLB use. However, the
operation is quite heavy weight on PA 1.X processors as we need to take
the TLB lock and a TLB broadcast is sent to all processors.
This patch removes the purges from flush_dcache_page_asm() and
flush_icache_page_asm.

The attached change interchanges the order of purging the TLB and
setting the corresponding page table entry. TLB purges are strongly
ordered. It occurred to me one night that setting the PTE first might
have subtle ordering issues on SMP machines and cause random memory
corruption.
A TLB lock guards the insertion of user TLB entries. So after the TLB
is purged, a new entry can't be inserted until the lock is released.
This ensures that the new PTE value is used when the lock is released.
Since making this change, no random segmentation faults have been
observed on the Debian hppa buildd servers.

It is required to have an early static cpu to node mapping. This patch
pins all possible cpus to nodes for which no topology information is
present. Since there is no interface available which would allow to
tell where a non-present cpu would appear topology-wise, simply use a
round robin algorithm.
Right now this makes sure that the cpu_to_node() function will return
the same value for a cpu during the life time of the system.

CPU topology information like cpu to node mapping must be setup in
setup_arch already. Topology information is currently made available
with a per cpu variable; this however will not work when the
initialization will be moved to setup_arch, since the generic percpu
setup will be done much later.
Therefore convert back to a cpu_topology array.

The toptree algorithm uses the physical core ids to create a mapping
between cores and nodes (to_node_id array within emu_cores structure).
The core ids are used as an index into an array which size depends on
CONFIG_NR_CPUS. If the physical core ids are larger, this will result
in out-of-bounds write accesses.
Generate logical core ids instead to avoid this.

The ptff() and clear_table() functions use the gcc extension "variable
length arrays in structures" (VLAIS) to define in the inline assembler
constraints the area of the clobbered memory. This extension will most
likely never be supported by LLVM/Clang.
Since currently BPF programs are compiled with LLVM, this leads to the
following compile errors:
$ cd samples/bpf
$ make

typedef struct { char _[len]; } addrtype;
To fix this do the following:
- Convert ptff() into a macro that then uses a fixed size array
when expanded.
- Convert the clear_table() function and use an inline assembly
with fixed size array in a loop.
The runtime performance of the new version is even better than
the old version (tested with EC12/z13 and gcc 4.8.5/6.2.1 with
"-march=z196 -O2").

For system damage machine checks or machine checks due to invalid PSW
fields the system will be stopped. In order to get an oops message out
before killing the system the machine check handler branches to
.Lmcck_panic, switches to the panic stack and then does the usual
machine check handling.
The switch to the panic stack is incomplete, the stack pointer in %r15
is replaced, but the pt_regs pointer in %r11 is not. The result is
a program check which will kill the system in a slightly different way.

In a similar fashion to how we handled exiting VLAN mode, move the logic
in i40e_vsi_add_vlan into i40e_sync_vsi_filters. Extract this logic into
its own function for ease of understanding as it will become quite
complex.
The new function, i40e_correct_mac_vlan_filters() correctly updates all
filters for when we need to enter VLAN mode, exit VLAN mode, and also
enforces the PVID when assigned.
Call i40e_correct_mac_vlan_filters from i40e_sync_vsi_filters passing it
the number of active VLAN filters, and the two temporary lists.
Remove the function for updating VLAN=0 filters from i40e_vsi_add_vlan.
The end result is that the logic for entering and exiting VLAN mode is
in one location which has the most knowledge about all filters. This
ensures that we always correctly have the non-VLAN filters assigned to
VID=0 or VID=-1 regardless of how we ended up getting to this result.
Additionally this enforces the PVID at sync time so that we know for
certain that an assigned PVID results in only filters with that PVID
will be added to the firmware.

The current flow for adding or updating the PVID for a VF uses
i40e_vsi_add_vlan and i40e_vsi_kill_vlan which each take, then release
the hash lock. In addition the two functions also must take special care
that they do not perform VLAN mode changes as this will make the code in
i40e_ndo_set_vf_port_vlan behave incorrectly.
Fix these issues by using the new helper functions i40e_add_vlan_all_mac
and i40e_rm_vlan_all_mac which expect the hash lock to already be taken.
Additionally these functions do not perform any state updates in regards
to VLAN mode, so they are safe to use in the PVID update flow.
It should be noted that we don't need the VLAN mode update code here,
because there are only a few flows here.
(a) we're adding a new PVID
In this case, if we already had VLAN filters the VSI is knocked
offline so we don't need to worry about pre-existing VLAN filters
(b) we're replacing an existing PVID
In this case, we can't have any VLAN filters except those with the old
PVID which we already take care of manually.
(c) we're removing an existing PVID
Similarly to above, we can't have any existing VLAN filters except
those with the old PVID which we already take care of correctly.
Because of this, we do not need (or even want) the special accounting
done in i40e_vsi_add_vlan, so use of the helpers is a saner alternative.
It also opens the door for a future patch which will refactor the flow
of i40e_vsi_add_vlan now that it is not needed in this function.

A future refactor of how the PF assigns a PVID to a VF will want to be
able to add and remove a block of filters by VLAN without worrying about
accidentally triggering the accounting for I40E_VLAN_ANY. Additionally
the PVID assignment would like to be able to batch several changes under
one use of the mac_filter_hash_lock.
Factor out the addition and deletion of a VLAN on all MACs into their
own function which i40e_vsi_(add|kill)_vlan can use. These new functions
expect the caller to take the hash lock, as well as perform any
necessary accounting for updating I40E_VLAN_ANY filters if we are now
operating under VLAN mode.

Fix a subtle issue with the code for converting VID=-1 filters into VID=0
filters when adding a new VLAN. Previously the code deleted the VID=-1
filter, and then added a new VID=0 filter. In the rare case that the
addition fails due to -ENOMEM, we end up completely deleting the filter
which prevents recovery if memory pressure subsides. While it is not
strictly an issue because it is likely that memory issues would result
in many other problems, we shouldn't delete the filter until after the
addition succeeds.

The current caller of i40e_update_filter_state incorrectly passes
aq_ret, an i40e_status variable, instead of the expected aq_err. This
happens to work because i40e_status is actually just a typedef integer,
and 0 is still the successful return. However i40e_update_filter_state
has special handling for ENOSPC which is currently being ignored.
Also notice that firmware does not update the per-filter response for
many types of errors, such as EINVAL. Thus, modify the filter setup so
that the firmware response memory is pre-set with I40E_AQC_MM_ERR_NO_RES.
This enables us to refactor i40e_update_filter_state, removing the need
to pass aq_err and avoiding a need for having 3 different flows for
checking the filter state.
The resulting code for i40e_update_filter_state is much simpler, only
a single loop and we always check each filter response value every time.
Since we pre-set the response value to match our expected error this

Previous code refactors have accidentally caused issues with the
counting of active_filters. Avoid similar issues in the future by simply
re-counting the active filters every time after we handle add and delete
of all the filters. Additionally this allows us to simplify the check
for when we exit promiscuous mode since we can combine the check for
failed filters at the same time.
Additionally since we recount filters at the end we need to set
vsi->promisc_threshold as well.
The resulting code takes a bit longer since we do have to loop over
filters again. However, the result is more readable and less likely to
become incorrect due to failed accounting of filters in the future.
Finally, this ensures that it is not possible for vsi->active_filters to
ever underflow since we never decrement it.

A product decision has been made to defeature detection of PTP frames
over L4 (UDP) on the XL710 MAC. Do not advertise support for L4
timestamping.

The service task lock was being set in the scheduling function, not the
actual service task. This would potentially leave the bit set for a long
time before the task actually ran. Furthermore, if the service task
takes too long, it calls the schedule function to reschedule itself -
which would fail to take the lock and do nothing.
Instead, set and clear the lock bit in the service task itself. In the
process, get rid of the i40e_service_event_complete() function, which is
really just two lines of code that can be put right in the service task
itself.

Depending on external PHY type, register access method should be
different. Clause22 or Clause45 can be chosen for different PHYs.
Implemented functions apply correct access method for used device.

Add support for 25G devices - defines and data structures.
One tricky part here is that the firmware support for these
Devices introduces a mismatch between the PHY type enum and
the bitfields for the phy types.
This change creates a macro and uses it to increment the 25G
PHY values when creating 25G bitfields.

Replace the %d specifier used for printing vsi->active_filters and
vsi->promisc_threshold with an unsigned %u format specifier. While it is
unlikely in practice that these values will ever reach such a large
number they are unsigned values and thus should not be interpreted as
negative numbers.
