76c13ede71 net: dsa: felix: use vcap policer to set flow meter for psfp
This patch add police action to set flow meter table which is defined
in IEEE802.1Qci. Flow metering is two rates two buckets and three color
marker to policing the frames, we only enable one rate one bucket in
this patch.

Flow metering shares a same policer pool with VCAP policers, so the PSFP
policer calls ocelot_vcap_policer_add() and ocelot_vcap_policer_del() to
set flow meter police.

77043c3709 net: mscc: ocelot: use index to set vcap policer
Policer was previously automatically assigned from the highest index to
the lowest index from policer pool. But police action of tc flower now
uses index to set an police entry. This patch uses the police index to
set vcap policers, so that one policer can be shared by multiple rules.

7d4b564d6a net: dsa: felix: support psfp filter on vsc9959
VSC9959 supports Per-Stream Filtering and Policing(PSFP) that complies
with the IEEE 802.1Qci standard. The stream is identified by Null stream
identification(DMAC and VLAN ID) defined in IEEE802.1CB.

For PSFP, four tables need to be set up: stream table, stream filter
table, stream gate table, and flow meter table. Identify the stream by
parsing the tc flower keys and add it to the stream table. The stream
filter table is automatically maintained, and its index is determined by
SGID(flow gate index) and FMID(flow meter index).

0fa68da72c net: ethernet: dec: tulip: de4x5: fix possible array overflows in type3_infoblock()
The definition of macro MOTO_SROM_BUG is:
  #define MOTO_SROM_BUG    (lp->active == 8 && (get_unaligned_le32(
  dev->dev_addr) & 0x00ffffff) == 0x3e0008)

and the if statement
  if (MOTO_SROM_BUG) lp->active = 0;

using this macro indicates lp->active could be 8. If lp->active is 8 and
the second comparison of this macro is false. lp->active will remain 8 in:
  lp->phy[lp->active].gep = (*p ? p : NULL); p += (2 * (*p) + 1);
  lp->phy[lp->active].rst = (*p ? p : NULL); p += (2 * (*p) + 1);
  lp->phy[lp->active].mc  = get_unaligned_le16(p); p += 2;
  lp->phy[lp->active].ana = get_unaligned_le16(p); p += 2;
  lp->phy[lp->active].fdx = get_unaligned_le16(p); p += 2;
  lp->phy[lp->active].ttm = get_unaligned_le16(p); p += 2;
  lp->phy[lp->active].mci = *p;

However, the length of array lp->phy is 8, so array overflows can occur.
To fix these possible array overflows, we first check lp->active and then
return -EINVAL if it is greater or equal to ARRAY_SIZE(lp->phy) (i.e. 8).

10GbE Intel Wired LAN Driver Updates 2021-11-17

Radoslaw Tyl says:

The change is a consequence of errors reported by the ixgbevf driver
while starting several virtual guests at the same time on ESX host.
During this, VF was not able to communicate correctly with the PF,
as a result reported "PF still in reset state. Is the PF interface up?"
and then goes to locked state. The only thing left was to reload
the VF driver on the guest OS.

The background of the problem is that the current PFU and VFU
semaphore locking mechanism between sender and receiver may cause
overriding Mailbox memory (VFMBMEM), in such scenario receiver of
the original message will read the invalid, corrupted or one (or more)
message may be lost.

This change is actually as a support for communication with PF ESX
driver and does not contains changes and support for ixgbe driver.
For maintain backward compatibility, previous communication method
has been preserved in the form of LEGACY functions.

In the future there is a plan to add a support for a 1.5 mailbox API
communication also to ixgbe driver.

This reverts commit d00e60ee54.

As reported by Guillaume in [1]:
Enabling LPAE always enables CONFIG_ARCH_DMA_ADDR_T_64BIT
in 32-bit systems, which breaks the bootup proceess when a
ethernet driver is using page pool with PP_FLAG_DMA_MAP flag.
As we were hoping we had no active consumers for such system
when we removed the dma mapping support, and LPAE seems like
a common feature for 32 bits system, so revert it.

a66998e0fb ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port()
The if statement:
  if (port >= DSAF_GE_NUM)
        return;

limits the value of port less than DSAF_GE_NUM (i.e., 8).
However, if the value of port is 6 or 7, an array overflow could occur:
  port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;

because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6).

To fix this possible array overflow, we first check port and if it is
greater than or equal to DSAF_MAX_PORT_NUM, the function returns.

b831281bb9 reiserfs: don't use congestion_wait()
Block devices do not, in general, report congestion any more, so this
congestion_wait() is effectively just a sleep.

It isn't entirely clear what is being waited for, but as we only wait
when j_async_throttle is elevated, it seems reasonable to stop waiting
when j_async_throttle becomes zero - or after the same timeout.

So change to use wait_event_event_timeout() for waiting, and
wake_up_var() to signal an end to waiting.

4017b230c9 parisc: Wrap assembler related defines inside __ASSEMBLY__
Building allmodconfig shows errors in the gpu/drm/msm snapdragon drivers,
because a COND() define is used there which conflicts with the COND() for
PA-RISC assembly.  Although the snapdragon driver isn't relevant for parisc, it
is nevertheless compiled when CONFIG_COMPILE_TEST is defined.

Move the COND() define and other PA-RISC mnemonics inside the #ifdef
__ASSEMBLY__ part to avoid this conflict.

6b285a5587 KVM: Disallow user memslot with size that exceeds "unsigned long"
Reject userspace memslots whose size exceeds the storage capacity of an
"unsigned long".  KVM's uAPI takes the size as u64 to support large slots
on 64-bit hosts, but does not account for the size being truncated on
32-bit hosts in various flows.  The access_ok() check on the userspace
virtual address in particular casts the size to "unsigned long" and will
check the wrong number of bytes.

KVM doesn't actually support slots whose size doesn't fit in an "unsigned
long", e.g. KVM's internal kvm_memory_slot.npages is an "unsigned long",
not a "u64", and misc arch specific code follows that behavior.

bda44d8447 KVM: Ensure local memslot copies operate on up-to-date arch-specific data
When modifying memslots, snapshot the "old" memslot and copy it to the
"new" memslot's arch data after (re)acquiring slots_arch_lock.  x86 can
change a memslot's arch data while memslot updates are in-progress so
long as it holds slots_arch_lock, thus snapshotting a memslot without
holding the lock can result in the consumption of stale data.

When recursively clearing out disconnected pts, the range based TLB
flush in handle_removed_tdp_mmu_page uses the wrong starting GFN,
resulting in the flush mostly missing the affected range. Fix this by
using base_gfn for the flush.

In response to feedback from David Matlack on the RFC version of this
patch, also move a few definitions into the for loop in the function to
prevent unintended references to them in the future.

82cc27eff4 KVM: s390: Cap KVM_CAP_NR_VCPUS by num_online_cpus()
KVM_CAP_NR_VCPUS is a legacy advisory value which on other architectures
return num_online_cpus() caped by KVM_CAP_NR_VCPUS or something else
(ppc and arm64 are special cases). On s390, KVM_CAP_NR_VCPUS returns
the same as KVM_CAP_MAX_VCPUS and this may turn out to be a bad
'advice'. Switch s390 to returning caped num_online_cpus() too.
