40GbE Intel Wired LAN Driver Updates 2018-03-14

This series contains updates to i40e and i40evf only.

Corentin Labbe cleans up the left over FCoE files in the i40e driver.

Gustavo A R Silva fixes a cut and paste error.

Paweł fixes a race condition when the VF driver is loaded on a host and
virsh is trying to attach it to the virtual machine and set a MAC
address.  Resolve the issue by adding polling in i40e_ndo_set_vf_mac()
when the VF is in reset mode.

Jake cleans up i40e_vlan_rx_register() since this only used in a single
location, so just inline the contents of the function.  Created a helper
function to proper update the per-filter statistics when we delete it.
Factored out the re-enabling ATR and SB rules.  Fixed an issue when
re-enabling ATR after the last TCPv4 filter is removed and ntuple is
still active, we were not restoring the TCPv4 filter input set.

Filip modifies the permission check function to ensure that it knows how
many filters are being requested, which allows the check to ensure that
the total number of filters in a single request does not cause us to go
over the limit.

Mariusz fixed an issue where the wrong calculation of partition id was
being done on OCP PHY mezzanine cards, which in turn caused wake on LAN
to be disabled on certain ports.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

When we re-enable ATR we need to restore the input set for TCPv4
filters, in order for ATR to function correctly. We already do this for
the normal case of re-enabling ATR when disabling ntuple support.
However, when re-enabling ATR after the last TCPv4 filter is removed (but
when ntuple support is still active), we did not restore the TCPv4
filter input set.

This can cause problems if the TCPv4 filters from FDir had changed the
input set, as ATR will no longer behave as expected.

When clearing the ATR auto-disable flag, make sure we restore the TCPv4
input set to avoid this.

This patch overwrites number of ports for X722 devices with support

The old method with checking if port is disabled in the PRTGEN_CNF
register cannot be used in this case. When the OCP is removed, ports
were seen as disabled, which resulted in wrong calculation of partition

When hardware has trouble with a particular filter, we delete it from

When VF requests adding of MAC filters the checking is done against number
of already present MAC filters not adding them at the same time. It makes
it possible to add a bunch of filters at once possibly exceeding
acceptable limit of I40E_VC_MAX_MAC_ADDR_PER_VF filters.

This happens because when checking vf->num_mac, we do not check how many
filters are being requested at once. Modify the check function to ensure
that it knows how many filters are being requested. This allows the
check to ensure that the total number of filters in a single request
does not cause us to go over the limit.

Additionally, move the check to within the lock to ensure that the
vf->num_mac is checked while holding the lock to maintain consistency.
We could have simply moved the call to i40e_vf_check_permission to
within the loop, but this could cause a request to be non-atomic, and
add some but not all the addresses, while reporting an error code. We
want to avoid this behavior so that users are not confused about which
filters have or have not been added.

We used to use the function i40e_vlan_rx_register as a way to hook
into the now defunct .ndo_vlan_rx_register netdev hook. This was
removed but we kept the function around because we still used it
internally to control enabling or disabling of VLAN stripping.

As pointed out in upstream review, VLAN stripping is only used in a
single location and the previous function is quite small, just inline
it into i40e_restore_vlan() rather than carrying the function

This patchset mainly adds support for SCTP AUTH Information for sendmsg,
described in RFC6458:

    5.3.8.  SCTP AUTH Information Structure (SCTP_AUTHINFO)

and also adds a sockopt described in RFC6458:

    8.3.4.  Deactivate a Shared Key (SCTP_AUTH_DEACTIVATE_KEY)

and two types of events for AUTHENTICATION_EVENT described in RFC6458:

             - SCTP_AUTH_NO_AUTH
             - SCTP_AUTH_FREE_KEY

      SCTP_AUTH_FREE_KEY:  This report indicates that the SCTP

After deactivating a key, it would never be used again, which means
it's refcnt can't be held/increased by new chunks. But there may be
some chunks in out queue still using it. So only when refcnt is 1,
which means no chunk in outqueue is using/holding this key either,
this EVENT would be sent.

When users receive this notification, they could do DEL_KEY sockopt to
remove this shkey, and also tell the peer that this key won't be used
in any chunk thoroughly from now on, then the peer can remove it as
well safely.

TIPC looks concentrated in itself, and other pernet_operations
seem not touching its entities.

tipc_net_ops look pernet-divided, and they should be safe to
be executed in parallel for several net the same time.

These pernet_operations create and destroy net::sctp::ctl_sock.
Since pernet_operations do not send sctp packets each other,
they look safe to be marked as async.

These pernet_operations have a deal with sysctl, /proc
entries and statistics. Also, there are freeing of
net::sctp::addr_waitq queue and net::sctp::local_addr_list
in exit method. All of them look pernet-divided, and it
seems these items are only interesting for sctp_defaults_ops,
which are safe to be executed in parallel.

Return error code -EINVAL in the address len check error handling
case since 'err' can be overwrite to 0 by 'err = sctp_verify_addr()'
in the for loop.

Sorry, one of the patches I sent in an earlier series
has some dumb mistakes. One was that I had changed the
parameter for the errata workaround function but forgot
to make that change in the code that called it.

The second mistake was a forgotten return value at the end
of the function in case the workaround was not needed.
