Commit 62622dab ("ima: return IMA digest value only when IMA_COLLECTED
flag is set") caused bpf_ima_inode_hash() to refuse to give non-fresh
digests. IMA test #3 assumed the old behavior, that bpf_ima_inode_hash()
still returned also non-fresh digests.

Correct the test by accepting both cases. If the samples returned are 1,
assume that the commit above is applied and that the returned digest is
fresh. If the samples returned are 2, assume that the commit above is not
applied, and check both the non-fresh and fresh digest.

Commit 0091bfc8 ("io_uring/af_unix: defer registered

This structure is critical for networking, and we try very hard
to not add bloat on it, unless absolutely required.

For instance, we can use a specific destructor as a wrapper
around unix_destruct_scm(), to identify skbs that unix_gc()
has to special case.

====================
Add support for TC flower templates in Sparx5

This adds support for the TC template mechanism in the Sparx5 flower filter
implementation.

Templates are as such handled by the TC framework, but when a template is
created (using a chain id) there are by definition no filters on this
chain (an error will be returned if there are any).

If the templates chain id is one that is represented by a VCAP lookup, then
when the template is created, we know that it is safe to use the keys
provided in the template to change the keyset configuration for the (port,
lookup) combination, if this is needed to improve the match on the
template.

The original port keyset configuration is captured in the template state
information which is kept per port, so that when the template is deleted
the port keyset configuration can be restored to its previous setting.

The template also provides the protocol parameter which is the basic
information that is used to find out which port keyset configuration needs
to be changed.

The VCAPs and lookups are slightly different when it comes to which keys,
keysets and protocol are supported and used for selection, so in some
cases a bit of tweaking is needed to find a useful match.  This is done by
e.g. removing a key that prevents the best matching keyset from being
selected.

The debugfs output that is provided for a port allows inspection of the
currently used keyset in each of the VCAPs lookups.  So when a template has
been created the debugfs output allows you to verify if the keyset
configuration has been changed successfully.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

This adds support for using the "template add" and "template destroy"
functionality to change the port keyset configuration.

If the VCAP lookup already contains rules, the port keyset is left
unchanged, as a change would make these rules unusable.

When the template is destroyed the port keyset configuration is restored.
The filters using the template chain will automatically be deleted by the
TC framework.

With this its is now possible for clients (like TC) to change the port
keyset configuration in the Sparx5 VCAPs.

This is typically done per traffic class which is guided with the L3
protocol information.
Before the change the current keyset configuration is collected in a list
that is handed back to the client.

This adds a list that is used to collect the templates that are active on a

This allows the template creation to change the port configuration

Zero-length arrays as fake flexible arrays are deprecated and we are
moving towards adopting C99 flexible-array members instead.

Transform zero-length array into flexible-array member in struct
mlx4_en_rx_desc.

Address the following warnings found with GCC-13 and
-fstrict-flex-arrays=3 enabled:
drivers/net/ethernet/mellanox/mlx4/en_rx.c:88:30: warning: array subscript i is outside array bounds of ‘struct mlx4_wqe_data_seg[0]’ [-Warray-bounds=]
drivers/net/ethernet/mellanox/mlx4/en_rx.c:149:30: warning: array subscript 0 is outside array bounds of ‘struct mlx4_wqe_data_seg[0]’ [-Warray-bounds=]

drivers/net/ethernet/mellanox/mlx4/en_rx.c:119:30: warning: array subscript i is outside array bounds of ‘struct mlx4_wqe_data_seg[0]’ [-Warray-bounds=]

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].

====================
r8169: disable ASPM during NAPI poll

This is a rework of ideas from Kai-Heng on how to avoid the known
ASPM issues whilst still allowing for a maximum of ASPM-related power
savings. As a prerequisite some locking is added first.
