Norbert reported that it's possible to race sys_perf_event_open() such
that the looser ends up in another context from the group leader,
triggering many WARNs.

The move_group case checks for races against itself, but the
!move_group case doesn't, seemingly relying on the previous
group_leader->ctx == ctx check. However, that check is racy due to not
holding any locks at that time.

Therefore, re-check the result after acquiring locks and bailing
if they no longer match.

Additionally, clarify the not_move_group case from the
move_group-vs-move_group race.

With shadow paging enabled, the INVPCID instruction results in a call
to kvm_mmu_invpcid_gva.  If INVPCID is executed with CR0.PG=0, the
invlpg callback is not set and the result is a NULL pointer dereference.
Fix it trivially by checking for mmu->invlpg before every call.

There are other possibilities:

- check for CR0.PG, because KVM (like all Intel processors after P5)
  flushes guest TLB on CR0.PG changes so that INVPCID/INVLPG are a
  nop with paging disabled

- check for EFER.LMA, because KVM syncs and flushes when switching
  MMU contexts outside of 64-bit mode

All of these are tricky, go for the simple solution.  This is CVE-2022-1789.

In kvm_hv_flush_tlb(), valid_bank_mask is declared as unsigned long,
but is used as u64, which is wrong for i386, and has been spotted by

hweight64()"

https://lore.kernel.org/lkml/20220510154750.212913-12-yury.norov@gmail.com/

But it's wrong even without that patch because now bitmap_weight()
dereferences a word after valid_bank_mask on i386.

Fix a goof in kvm_prepare_memory_region() where KVM fails to free the
new memslot's dirty bitmap during a CREATE action if
kvm_arch_prepare_memory_region() fails.  The logic is supposed to detect
if the bitmap was allocated and thus needs to be freed, versus if the
bitmap was inherited from the old memslot and thus needs to be kept.  If
there is no old memslot, then obviously the bitmap can't have been
inherited

The bug was exposed by commit 86931ff7 ("KVM: x86/mmu: Do not create
SPTEs for GFNs that exceed host.MAXPHYADDR"), which made it trivally easy
for syzkaller to trigger failure during kvm_arch_prepare_memory_region(),
but the bug can be hit other ways too, e.g. due to -ENOMEM when
allocating x86's memslot metadata.

it is matched correctly in the pmu event filter and not inadvertently

select gets truncated away only leaving the bottom byte[2] left for
matching.

This is a contrived example used for the convenience of demonstrating
this issue, however, this can be applied to event selects 0x28A (OC

being denied when the event select was only set up to deny 0x28A.

 "We had two big outstanding issues after v5.18-rc6:

   a) 32-bit kernels on 64-bit machines (e.g. on a C3700 which is able
      to run 32- and 64-bit kernels) failed early in userspace.

   b) 64-bit kernels on PA8800/PA8900 CPUs (e.g. in a C8000) showed
      random userspace segfaults. We assumed that those problems were
      caused by the tmpalias flushes.

  Dave did a lot of testing and reorganization of the current flush code
  and fixed the 32-bit cache flushing. For PA8800/PA8900 CPUs he
  switched the code to flush using the virtual address of user and
  kernel pages instead of using tmpalias flushes. The tmpalias flushes
  don't seem to work reliable on such CPUs.

  We tested the patches on a wide range machines (715/64, B160L, C3000,
  C3700, C8000, rp3440) and they have been in for-next without any
  conflicts.

  Summary:

   - Rewrite the cache flush code for PA8800/PA8900 CPUs to flush using
     the virtual address of user and kernel pages instead of using
     tmpalias flushes. Testing showed, that tmpalias flushes don't work

It turned out that polling period for MMC_SEND_OP_COND, that currently is
set to 1ms, still isn't sufficient. In particular a Micron eMMC on a
Beaglebone platform, is reported to sometimes fail to initialize.

Additional test, shows that extending the period to 4ms is working fine, so
let's make that change.

When removing short term pins, I've changed the the batch buffer
pinning for relocation to use __i915_vma_pin, because
i915_gem_object_ggtt_pin_ww was destroying the old vma. This
caused regressions, because the functions are not identical.

Fix the regressions by calling i915_gem_object_ggtt_pin_ww() again
on ggtt-only platforms, but only if the batch can be pinned without
being moved.

It is possible to stack bridges on top of each other. Consider the
following which makes use of an Ethernet switch:

       br1
     /    \
    /      \
   /        \
 br0.11    wlan0
   |
   br0
 /  |  \
p1  p2  p3

br0 is offloaded to the switch. Above br0 is a vlan interface, for
vlan 11. This vlan interface is then a slave of br1. br1 also has a
wireless interface as a slave. This setup trunks wireless lan traffic
over the copper network inside a VLAN.

A frame received on p1 which is passed up to the bridge has the
skb->offload_fwd_mark flag set to true, indicating that the switch has
dealt with forwarding the frame out ports p2 and p3 as needed. This
flag instructs the software bridge it does not need to pass the frame
back down again. However, the flag is not getting reset when the frame
is passed upwards. As a result br1 sees the flag, wrongly interprets
it, and fails to forward the frame to wlan0.

When passing a frame upwards, clear the flag. This is the Rx
equivalent of br_switchdev_frame_unmark() in br_dev_xmit().

In the detach path, the driver calls sysfs_remove_group() for the
groups it believes has been registered.  However, if the group was
never previously registered, then this causes a splat.

Instead, compute the groups that should be registered in advance,
and then call sysfs_create_groups(), which registers them all at once.

Update the error handling appropriately.

Pablo Neira Ayuso says:

====================
Netfilter fixes for net

1) Reduce number of hardware offload retries from flowtable datapath
   which might hog system with retries, from Felix Fietkau.

2) Skip neighbour lookup for PPPoE device, fill_forward_path() already
   provides this and set on destination address from fill_forward_path for
   PPPoE device, also from Felix.

4) When combining PPPoE on top of a VLAN device, set info->outdev to the
   PPPoE device so software offload works, from Felix.

5) Fix TCP teardown flowtable state, races with conntrack gc might result
   in resetting the state to ESTABLISHED and the time to one day. Joint
   work with Oz Shlomo and Sven Auhagen.

6) Call dst_check() from flowtable datapath to check if dst is stale
   instead of doing it from garbage collector path.

7) Disable register tracking infrastructure, either user-space or
   kernel need to pre-fetch keys inconditionally, otherwise register
   tracking assumes data is already available in register that might
   not well be there, leading to incorrect reductions.
