TC actions don't need to respect RCU grace period, because it
is either just detached from tc filter (standalone case) or
it is removed together with tc filter (bound case) in which case
RCU grace period is already respected at filter layer.

Reserved and unused fields in the Tx descriptors should be 0. The PPv2
driver doesn't clear them at run-time (for performance reasons) but
these descriptors aren't zeroed when allocated, which can lead to
unpredictable behaviors. This patch fixes this by using
dma_zalloc_coherent instead of dma_alloc_coherent.

Instead, just fall back on the new '%p' behavior which hashes the
pointer.

Otherwise, '%pK' - that was intended to mark a pointer as restricted -
just ends up leaking pointers that a normal '%p' wouldn't leak.  Which
just make the whole thing pointless.

I suspect we should actually get rid of '%pK' entirely, and make it just
work as '%p' regardless, but this is the minimal obvious fix.  People
who actually use 'kptr_restrict' should weigh in on which behavior they
want.

Pull printk pointer hashing update from Tobin Harding:
 "Here is the patch set that implements hashing of printk specifier %p.

  First we have two clean up patches then we do the hashing. Hashing is
  done via the SipHash algorithm. The next patch adds printk specifier
  %px for printing pointers when we _really_ want to see the address i.e
  %px is functionally equivalent to %lx. Final patch in the set fixes
  KASAN since we break it by hashing %p.

  For the record here is the justification for the series:

    Currently there exist approximately 14 000 places in the Kernel
    where addresses are being printed using an unadorned %p. This
    potentially leaks sensitive information about the Kernel layout in
    memory. Many of these calls are stale, instead of fixing every call
    we hash the address by default before printing. We then add %px to
    provide a way to print the actual address. Although this is
    achievable using %lx, using %px will assist us if we ever want to
    change pointer printing behaviour. %px is more uniquely grep'able
    (there are already >50 000 uses of %lx).

    The added advantage of hashing %p is that security is now opt-out,
    if you _really_ want the address you have to work a little harder
    and use %px.

  This will of course break some users, forcing code printing needed
  addresses to be updated"

[ I do expect this to be an annoyance, and a number of %px users to be
  added for debuggability. But nobody is willing to audit existing %p
  users for information leaks, and a number of places really only use
  the pointer as an object identifier rather than really 'I need the
  address'.

  IOW - sorry for the inconvenience, but it's the least inconvenient of
  the options.    - Linus ]

This reverts commit 152e93af.

It was a nice cleanup in theory, but as Nicolai Stange points out, we do
need to make the page dirty for the copy-on-write case even when we
didn't end up making it writable, since the dirty bit is what we use to

Repeat terminal ACKs and now terminal ACKs are now generated from the
connection event processor rather from call handling as this allows us to
discard client call structures as soon as possible and free up the channel
for a follow on call.

However, in ACKs so generated, the additional information trailer is
malformed because the padding that's meant to be in the middle isn't
included in what's transmitted.

Fix it so that the 3 bytes of padding are included in the transmission.

Further, the trailer is misaligned because of the padding, so assigment to
the u16 and u32 fields inside it might cause problems on some arches, so
fix this by breaking the padding and the trailer out of the packed struct.

(This also deals with potential compiler weirdies where some of the nested
structs are packed and some aren't).

The symptoms can be seen in wireshark as terminal DUPLICATE or IDLE ACK
packets in which the Max MTU, Interface MTU and rwind fields have weird
values and the Max Packets field is apparently missing.

the already existent 50 000 %lx call sites. Let's add specifier %px as a
clear, opt-in, way to print a pointer and maintain some level of
isolation from all the other hex integer output within the Kernel.

When cls_bpf offload was added it seemed like a good idea to
call cls_bpf_delete_prog() instead of extending the error
handling path, since the software state is fully initialized
at that point.  This handling of errors without jumping to
the end of the function is error prone, as proven by later
commit missing that extra call to __cls_bpf_delete_prog().

__cls_bpf_delete_prog() is now expected to be invoked with
a reference on exts->net or the field zeroed out.  The call
on the offload's error patch does not fullfil this requirement,
leading to each error stealing a reference on net namespace.

Create a function undoing what cls_bpf_set_parms() did and
use it from __cls_bpf_delete_prog() and the error path.
