This change implements CPUMAP redirect support for generic XDP programs.
The idea is to reuse the cpu map entry's queue that is used to push
native xdp frames for redirecting skb to a different CPU. This will
match native XDP behavior (in that RPS is invoked again for packet
reinjected into networking stack).

To be able to determine whether the incoming skb is from the driver or
cpumap, we reuse skb->redirected bit that skips generic XDP processing
when it is set. To always make use of this, CONFIG_NET_REDIRECT guard on
it has been lifted and it is always available.

>From the redirect side, we add the skb to ptr_ring with its lowest bit
set to 1.  This should be safe as skb is not 1-byte aligned. This allows
kthread to discern between xdp_frames and sk_buff. On consumption of the
ptr_ring item, the lowest bit is unset.

In the end, the skb is simply added to the list that kthread is anyway
going to maintain for xdp_frames converted to skb, and then received
again by using netif_receive_skb_list.

Bulking optimization for generic cpumap is left as an exercise for a
future patch for now.

Since cpumap entry progs are now supported, also remove check in
generic_xdp_install for the cpumap.

cpumap needs to set, clear, and test the lowest bit in skb pointer in
various places. To make these checks less noisy, add pointer friendly
bitop macros that also do some typechecking to sanitize the argument.

These wrap the non-atomic bitops __set_bit, __clear_bit, and test_bit
but for pointer arguments. Pointer's address has to be passed in and it
is treated as an unsigned long *, since width and representation of
pointer and unsigned long match on targets Linux supports. They are
prefixed with double underscore to indicate lack of atomicity.

This helper can later be utilized in code that runs cpumap and devmap
programs in generic redirect mode and adjust skb based on changes made
to xdp_buff.

When returning XDP_REDIRECT/XDP_TX, it invokes __skb_push, so whenever a
generic redirect path invokes devmap/cpumap prog if set, it must
__skb_pull again as we expect mac header to be pulled.

It also drops the skb_reset_mac_len call after do_xdp_generic, as the
mac_header and network_header are advanced by the same offset, so the
difference (mac_len) remains constant.

Add a test for using xdp_md as a context to BPF_PROG_TEST_RUN for XDP
programs.

The test uses a BPF program that takes in a return value from XDP
meta data, then reduces the size of the XDP meta data by 4 bytes.

Test cases validate the possible failure cases for passing in invalid
xdp_md contexts, that the return value is successfully passed
in, and that the adjusted meta data is successfully copied out.

contexts for BPF_PROG_TEST_RUN.

The intended use case is to allow testing XDP programs that make decisions
based on the ingress interface or RX queue.

If ingress_ifindex is specified, look up the device by the provided index
in the current namespace and use its xdp_rxq for the xdp_buff. If the
rx_queue_index is out of range, or is non-zero when the ingress_ifindex is
0, return -EINVAL.

Support passing a xdp_md via ctx_in/ctx_out in bpf_attr for
BPF_PROG_TEST_RUN.

The intended use case is to pass some XDP meta data to the test runs of
XDP programs that are used as tail calls.

For programs that use bpf_prog_test_run_xdp, support xdp_md input and
output. Unlike with an actual xdp_md during a non-test run, data_meta must
be 0 because it must point to the start of the provided user data. From
the initial xdp_md, use data and data_end to adjust the pointers in the
generated xdp_buff. All other non-zero fields are prohibited (with
EINVAL). If the user has set ctx_out/ctx_size_out, copy the (potentially
different) xdp_md back to the userspace.

We require all fields of input xdp_md except the ones we explicitly
support to be set to zero. The expectation is that in the future we might
add support for more fields and we want to fail explicitly if the user
runs the program on the kernel where we don't yet support them.

The DSA core has a layered structure, and even though we end up
returning 0 (success) to user space when setting a bonding/team upper
that can't be offloaded, some parts of the framework actually need to
know that we couldn't offload that.

For example, if dsa_switch_lag_join returns 0 as it currently does,
dsa_port_lag_join has no way to tell a successful offload from a
software fallback, and it will call dsa_port_bridge_join afterwards.
Then we'll think we're offloading the bridge master of the LAG, when in
fact we're not even offloading the LAG. In turn, this will make us set
skb->offload_fwd_mark = true, which is incorrect and the bridge doesn't
like it.

Introducing a new mailbox to support updating lmt entries
and common lmt base address scheme i.e. multiple pcifuncs
can share lmt region to reduce L1 cache pressure for application.
Parameters passed to mailbox includes the primary pcifunc
value whose lmt regions will be shared by other secondary
pcifuncs. Here secondary pcifunc will be the one who is
calling the mailbox.
For example:
By default each pcifunc has its own LMT base address:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR B
        PCIFUNC3    LMT_BASE_ADDR C
        PCIFUNC4    LMT_BASE_ADDR D
Application will choose PCIFUNC1 as base/primary pcifunc
and as and when other pcifunc(secondary pcifuncs) gets
probed, this mailbox will be called and LMTST table will
be updated as:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR A
        PCIFUNC3    LMT_BASE_ADDR A

Pull audit updates from Paul Moore:
 "Another merge window, another small audit pull request.

  Four patches in total: one is cosmetic, one removes an unnecessary
  initialization, one renames some enum values to prevent name
  collisions, and one converts list_del()/list_add() to list_move().

  None of these are earth shattering and all pass the audit-testsuite
  tests while merging cleanly on top of your tree from earlier today"

Pull SELinux updates from Paul Moore:

 - The slow_avc_audit() function is now non-blocking so we can remove
   the AVC_NONBLOCKING tricks; this also includes the 'flags' variant of
   avc_has_perm().

 - Use kmemdup() instead of kcalloc()+copy when copying parts of the
   SELinux policydb.

 - The InfiniBand device name is now passed by reference when possible
   in the SELinux code, removing a strncpy().

 - Minor cleanups including: constification of avtab function args,
   removal of useless LSM/XFRM function args, SELinux kdoc fixes, and
   removal of redundant assignments.
