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.

The conditional kallsym hex printing used a special fixed-width '%lx'
output (KALLSYM_FMT) in preparation for the hashing of %p, but that
series ended up adding a %px specifier to help with the conversions.

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
check that we've gone through a COW cycle.

printk specifier %p now hashes all addresses before printing. Sometimes
we need to see the actual unmodified address. This can be achieved using
%lx but then we face the risk that if in future we want to change the
way the Kernel handles printing of pointers we will have to grep through
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.

syzkaller found a race condition fanout_demux_rollover() while removing
a packet socket from a fanout group.

po->rollover is read and operated on during packet_rcv_fanout(), via
fanout_demux_rollover(), but the pointer is currently cleared before the
synchronization in packet_release().   It is safer to delay the cleanup
until after synchronize_net() has been called, ensuring all calls to
packet_rcv_fanout() for this socket have finished.

To further simplify synchronization around the rollover structure, set
po->rollover in fanout_add() only if there are no errors.  This removes
the need for rcu in the struct and in the call to
packet_getsockopt(..., PACKET_ROLLOVER_STATS, ...).

sctp: fix some other sparse errors

After the last fixes for sparse errors, there are still three sparse
errors in sctp codes, two of them are type cast, and the other one
is using extern.

Now each stream sched ops is defined in different .c file and
added into the global ops in another .c file, it uses extern
to make this work.

However extern is not good coding style to get them in and
even make C=2 reports errors for this.

This patch adds sctp_sched_ops_xxx_init for each stream sched
ops in their .c file, then get them into the global ops by
calling them when initializing sctp module.

Now sctp_csum_xxx doesn't really match the param types of these common
csum apis. As sctp_csum_xxx is defined in sctp/checksum.h, many sparse
errors occur when make C=2 not only with M=net/sctp but also with other
modules that include this header file.

This patch is to force them fit in csum apis with the right types.

Error code returned by 'bnxt_read_sfp_module_eeprom_info()' is handled a
few lines above when reading the A0 portion of the EEPROM.
The same should be done when reading the A2 portion of the EEPROM.

In order to correctly propagate an error, update 'rc' in this 2nd call as
well, otherwise 0 (success) is returned.

The Marvell 10G PHY driver supports different hardware revisions, which
have their bits 3..0 differing. To get the correct revision number these
bits should be ignored. This patch fixes this by using the already
defined MARVELL_PHY_ID_MASK (0xfffffff0) instead of the custom
0xffffffff mask.
