The existing net,mac test didn't cover the issue recently reported
by Nikita Yushchenko, where MAC addresses wouldn't match if given
as first field of a concatenated set with AVX2 and 8-bit groups,
because there's a different code path covering the lookup of six
8-bit groups (MAC addresses) if that's the first field.
Add a similar mac,net test, with MAC address and IPv4 address
swapped in the set specification.

The sixth byte of packet data has to be looked up in the sixth group,
not in the seventh one, even if we load the bucket data into ymm6
(and not ymm5, for convenience of tracking stalls).
Without this fix, matching on a MAC address as first field of a set,
if 8-bit groups are selected (due to a small set size) would fail,
that is, the given MAC address would never match.

After the below patch, the conntrack attached to skb is set to "notrack" in
the context of vrf device, for locally generated packets.
But this is true only when the default qdisc is set to the vrf device. When
changing the qdisc, notrack is not set anymore.
In fact, there is a shortcut in the vrf driver, when the default qdisc is
set, see commit dcdd43c41e60 ("net: vrf: performance improvements for
IPv4") for more details.
This patch ensures that the behavior is always the same, whatever the qdisc
is.
To demonstrate the difference, a new test is added in conntrack_vrf.sh.

Adding filters with the same values inside for VXLAN and Geneve causes HW
error, because it looks exactly the same. To choose between different
type of tunnels new recipe is needed. Add storing tunnel types in
creating recipes function and start checking it in finding function.
Change getting open tunnels function to return port on correct tunnel
type. This is needed to copy correct port to dummy packet.
Block user from adding enc_dst_port via tc flower, because VXLAN and
Geneve filters can be created only with destination port which was
previously opened.

In tunnels packet there can be two UDP headers:
- outer which for hw should be mark as ICE_UDP_OF
- inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if
inner header is of TCP type
In none tunnels packet header can be:
- UDP, which for hw should be mark as ICE_UDP_ILOS
- TCP, which for hw should be mark as ICE_TCP_IL
Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS.
ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to
error from hw while adding this kind of recipe.
In summary, for tunnel outer port type should always be set to
ICE_UDP_OF, for none tunnel outer and tunnel inner it should always be
set to ICE_UDP_ILOS.

If the hardware is constantly receiving unicast or broadcast packets
during driver load, the device previously counted many GLV_RDPC (VSI
dropped packets) events during init. This causes confusing dropped
packet statistics during driver load. The dropped packets counter
incrementing does stop once the driver finishes loading.
Avoid this problem by baselining our statistics at the end of driver
open instead of the end of probe.

The patch that implemented DSCP QoS implementation removed a
bandwidth check that was used to check for a specific condition
caused by some corner cases. This check should not of been
removed.
The same patch also added a check for when the DCBx state could
be changed in relation to DSCP, but the check was erroneously
added nested in a check for CEE mode, which made the check useless.
Fix these problems by re-adding the bandwidth check and relocating
the DSCP mode check earlier in the function that changes DCBx state
in the driver.

====================
can 2021-12-07
The 1st patch is by Vincent Mailhol and fixes a use after free in the
pch_can driver.
Dan Carpenter fixes a use after free in the ems_pcmcia sja1000 driver.
The remaining 7 patches target the m_can driver. Brian Silverman
contributes a patch to disable and ignore the ELO interrupt, which is
currently not handled in the driver and may lead to an interrupt
storm. Vincent Mailhol's patch fixes a memory leak in the error path
of the m_can_read_fifo() function. The remaining patches are
contributed by Matthias Schiffer, first a iomap_read_fifo() and
iomap_write_fifo() functions are fixed in the PCI glue driver, then
the clock rate for the Intel Ekhart Lake platform is fixed, the last 3
patches add support for the custom bit timings on the Elkhart Lake
platform.

As part of multiple customer escalations due to file data corruption
after copy on write operations, I wrote some fstests that use fsstress
to hammer on COW to shake things loose. Regrettably, I caught some
filesystem shutdowns due to incorrect rmap operations with the following
loop:
mount <filesystem> # (0)
fsstress <run only readonly ops> & # (1)
while true; do
fsstress <run all ops>
mount -o remount,ro # (2)
fsstress <run only readonly ops>
mount -o remount,rw # (3)
done
When (2) happens, notice that (1) is still running. xfs_remount_ro will
call xfs_blockgc_stop to walk the inode cache to free all the COW
extents, but the blockgc mechanism races with (1)'s reader threads to
take IOLOCKs and loses, which means that it doesn't clean them all out.
Call such a file (A).
When (3) happens, xfs_remount_rw calls xfs_reflink_recover_cow, which
walks the ondisk refcount btree and frees any COW extent that it finds.
This function does not check the inode cache, which means that incore
COW forks of inode (A) is now inconsistent with the ondisk metadata. If
one of those former COW extents are allocated and mapped into another
file (B) and someone triggers a COW to the stale reservation in (A), A's
dirty data will be written into (B) and once that's done, those blocks
will be transferred to (A)'s data fork without bumping the refcount.
The results are catastrophic -- file (B) and the refcount btree are now
corrupt. Solve this race by forcing the xfs_blockgc_free_space to run
synchronously, which causes xfs_icwalk to return to inodes that were
skipped because the blockgc code couldn't take the IOLOCK. This is safe
to do here because the VFS has already prohibited new writer threads.

[Why]
During dcn31_stream_encoder_create, if PHYC/D get remapped to F/G on B0
then we'll index 5 or 6 into a array of length 5 - leading to an
access violation on some configs during device creation.
[How]
Software won't be touching PHYF/PHYG directly, so just extend the
array to cover all possible engine IDs.
Even if it does by try to access one of these registers by accident

To avoid hanging RDPCSPIPE when INTERCEPTB isn't set.
DMCUB owns control of that bit so DMCUB should manage returning the

[Why]
When HPD IRQ occurs, it triggers a PSR disable and reenable
directly through dc layer.
Since it does not pass through the power layer, the layer
that tracks whether PSR is enabled or disabled and which
masks are set, this layer is now out of sync with the real
PSR state in FW.
Theoretically PSR can be enabled during hw programming
sequences or any other situation where we must disable PSR.
[How]
Check if PSR is enabled before doing PSR disable/reenable.

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.
[How]
Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.
Guard both instances of the outbox interrupt enable or we'll hang
during restore on ASIC that don't support it.

'irdma_prm_add_pble_mem()'
'pchunk->bitmapbuf' is a bitmap. Its size (in number of bits) is stored in
'pchunk->sizeofbitmap'.
When it is allocated, the size (in bytes) is computed by:
size_in_bits >> 3
There are 2 issues (numbers bellow assume that longs are 64 bits):
- there is no guarantee here that 'pchunk->bitmapmem.size' is modulo
BITS_PER_LONG but bitmaps are stored as longs
(sizeofbitmap=8 bits will only allocate 1 byte, instead of 8 (1 long))
- the number of bytes is computed with a shift, not a round up, so we
may allocate less memory than needed
(sizeofbitmap=65 bits will only allocate 8 bytes (i.e. 1 long), when 2
longs are needed = 16 bytes)
Fix both issues by using 'bitmap_zalloc()' and remove the useless
'bitmapmem' from 'struct irdma_chunk'.
While at it, remove some useless NULL test before calling
kfree/bitmap_free.

This buffer is currently allocated in hfi1_init():
if (reinit)
ret = init_after_reset(dd);
else
ret = loadtime_init(dd);
if (ret)
goto done;
/* allocate dummy tail memory for all receive contexts */
dd->rcvhdrtail_dummy_kvaddr = dma_alloc_coherent(&dd->pcidev->dev,
sizeof(u64),
&dd->rcvhdrtail_dummy_dma,
GFP_KERNEL);
if (!dd->rcvhdrtail_dummy_kvaddr) {
dd_dev_err(dd, "cannot allocate dummy tail memory\n");
ret = -ENOMEM;
goto done;
}
The reinit triggered path will overwrite the old allocation and leak it.
Fix by moving the allocation to hfi1_alloc_devdata() and the deallocation
to hfi1_free_devdata().
