In iwl_pcie_ctxt_info_gen3_init there are cases that the allocated dma
memory is leaked in case of error.
DMA memories prph_scratch, prph_info, and ctxt_info_gen3 are allocated
and initialized to be later assigned to trans_pcie. But in any error case
before such assignment the allocated memories should be released.
First of such error cases happens when iwl_pcie_init_fw_sec fails.
Current implementation correctly releases prph_scratch. But in two
sunsequent error cases where dma_alloc_coherent may fail, such
releases are missing.
This commit adds release for prph_scratch when allocation for
prph_info fails, and adds releases for prph_scratch and prph_info when
allocation for ctxt_info_gen3 fails.

We got a crash in iwl_trans_pcie_get_cmdlen(), while the TFD was
being accessed to sum up the lengths.
We want to access the TFD here, which is the information for the
hardware. We always only allocate 32 buffers for the cmd queue,
but on newer hardware (using TFH) we can also allocate only a
shorter hardware array, also only 32 TFDs. Prior to the TFH, we
had to allocate a bigger TFD array but would make those point to
a smaller set of buffers.
Additionally, now max_tfd_queue_size is up to 65536, so we can
access *way* out of bounds of a really only 32-entry array, so
it crashes.
Fix this by making the TFD index depend on which hardware we are
using right now.
While changing the calculation, also fix it to not use void ptr
arithmetic, but cast to u8 * before.

Consider the following flow:
1. Driver starts to sync the rx queues due to a delba.
mvm->queue_sync_cookie=1.
This rx-queues-sync is synchronous, so it doesn't increment the
cookie until all rx queues handle the notification from FW.
2. During this time, driver starts to sync rx queues due to nssn sync
required.
The cookie's value is still 1, but it doesn't matter since this
rx-queue-sync is non-synchronous so in the notification handler the
cookie is ignored.
What _does_ matter is that this flow increments the cookie to 2
immediately.
Remember though that the FW won't start servicing this command until
it's done with the previous one.
3. FW is still handling the first command, so it sends a notification
with internal_notif->sync=1, and internal_notif->cookie=0, which
triggers a WARN_ONCE.
The solution for this race is to only use the mvm->queue_sync_cookie in
case of a synchronous sync-rx-queues. This way in step 2 the cookie's
value won't change so we avoid the WARN.
The commit in the "fixes" field is the first commit to introduce
non-synchronous sending of this command to FW.

xennet_fill_frags() uses ~0U as return value when the sk_buff is not able
to cache extra fragments. This is incorrect because the return type of
xennet_fill_frags() is RING_IDX and 0xffffffff is an expected value for
ring buffer index.
In the situation when the rsp_cons is approaching 0xffffffff, the return
value of xennet_fill_frags() may become 0xffffffff which xennet_poll() (the
caller) would regard as error. As a result, queue->rx.rsp_cons is set
incorrectly because it is updated only when there is error. If there is no
error, xennet_poll() would be responsible to update queue->rx.rsp_cons.
Finally, queue->rx.rsp_cons would point to the rx ring buffer entries whose
queue->rx_skbs[i] and queue->grant_rx_ref[i] are already cleared to NULL.
This leads to NULL pointer access in the next iteration to process rx ring
buffer entries.
The symptom is similar to the one fixed in
commit 00b368502d ("xen-netfront: do not assume sk_buff_head list is
empty in error handling").
This patch changes the return type of xennet_fill_frags() to indicate
whether it is successful or failed. The queue->rx.rsp_cons will be
always updated inside this function.

This patch is syncing driver with actual devicetree documentation:
Documentation/devicetree/bindings/net/qca,ar71xx.txt
|Optional subnodes:
|- mdio : specifies the mdio bus, used as a container for phy nodes
| according to phy.txt in the same directory
The driver was working with fixed phy without any noticeable issues. This bug
was uncovered by introducing dsa ar9331-switch driver.
Since no one reported this bug until now, I assume no body is using it
and this patch should not brake existing system.

Commit b6b6cc9acd, changed the call to dwxgmac2_rss_write_reg()
passing it the variable cfg->key[i].
As key is an u8 but we write 32 bits at a time we need to cast it into
an u32 so that the correct key values are written. Notice that the for
loop already takes this into account so we don't try to write past the

commit 174e23810c
("sk_buff: drop all skb extensions on free and skb scrubbing") made napi
recycle always drop skb extensions. The additional skb_ext_del() that is
performed via nf_reset on napi skb recycle is not needed anymore.
Most nf_reset() calls in the stack are there so queued skb won't block
'rmmod nf_conntrack' indefinitely.
This removes the skb_ext_del from nf_reset, and renames it to a more
fitting nf_reset_ct().
In a few selected places, add a call to skb_ext_reset to make sure that
no active extensions remain.
I am submitting this for "net", because we're still early in the release
cycle. The patch applies to net-next too, but I think the rename causes
needless divergence between those trees.

Background: the switch only offers partial RX timestamps (24 bits) and
it is up to the driver to read the PTP clock to fill those timestamps up
to 64 bits. But the PTP clock readout needs to happen quickly enough (in
0.135 seconds, in fact), otherwise the PTP clock will wrap around 24
bits, condition which cannot be detected.
Looking at the 'max 134217731' value on output line 3, one can see that
in hex it is 0x8000003. Because the PTP clock resolution is 8 ns,
that means 0x1000000 in ticks, which is exactly 2^24. So indeed this is
a PTP clock wraparound, but the reason might be surprising.
What is going on is that sja1105_tstamp_reconstruct(priv, now, ts)
expects a "now" time that is later than the "ts" was snapshotted at.
This, of course, is obvious: we read the PTP time _after_ the partial RX
timestamp was received. However, the workqueue is processing frames from
a skb queue and reuses the same PTP time, read once at the beginning.
Normally the skb queue only contains one frame and all goes well. But
when the skb queue contains two frames, the second frame that gets
dequeued might have been partially timestamped by the RX MAC _after_ we
had read our PTP time initially.
The code was originally like that due to concerns that SPI access for
PTP time readout is a slow process, and we are time-constrained anyway
(aka: premature optimization). But some timing analysis reveals that the
time spent until the RX timestamp is completely reconstructed is 1 order
of magnitude lower than the 0.135 s deadline even under worst-case
conditions. So we can afford to read the PTP time for each frame in the
RX timestamping queue, which of course ensures that the full PTP time is
in the partial timestamp's future.

When a port is created, its VLAN filters are not cleared by the
firmware. This causes tagged packets to be later dropped by the ingress
STP filters, which default to DISCARD state.
The above did not matter much until commit b5ce611fd9 ("mlxsw:
spectrum: Add devlink-trap support") where we exposed the drop reason to
users.
Without this patch, the drop reason users will see is not consistent. If
a port is enslaved to a VLAN-aware bridge and a packet with an invalid
VLAN tries to ingress the bridge, it will be dropped due to ingress STP
filter. If the VLAN is later enabled and then disabled, the packet will
be dropped by the ingress VLAN filter despite the above being a
seemingly NOP operation.
Fix this by clearing all the VLAN filters during port initialization.
Adjust the test accordingly.

However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This

The size of individual pages in the page pool in given by an order. The
order is the binary logarithm of the number of pages that make up one of
the pages in the pool. However, the driver currently passes the number
of pages rather than the order, so it ends up wasting quite a bit of
memory.
Fix this by taking the binary logarithm and passing that in the order
field.

The issue was caused by skb's true_size changed without its sk's
sk_wmem_alloc increased in tcp/skb_gro_receive(). Later when the
skb is being freed and the skb's truesize is subtracted from its
sk's sk_wmem_alloc in tcp_wfree(), underflow occurs.
macsec is calling gro_cells_receive() to receive a packet, which
actually requires skb->sk to be NULL. However when macsec dev is
over veth, it's possible the skb->sk is still set if the skb was
not unshared or expanded from the peer veth.
ip_rcv() is calling skb_orphan() to drop the skb's sk for tproxy,
but it is too late for macsec's calling gro_cells_receive(). So
fix it by dropping the skb's sk earlier on rx path of macsec.

Commit a5681e20b5 ("net/ibmnvic: Fix deadlock problem in reset")
made the change to hold the RTNL lock during a reset to avoid deadlock
but linkwatch_event is fired during the reset and needs the RTNL lock.
That keeps linkwatch_event process from proceeding until the reset
is complete. The reset process cannot tolerate the linkwatch_event
processing after reset completes, so release the RTNL lock during the
process to allow a chance for linkwatch_event to run during reset.
This does not guarantee that the linkwatch_event will be processed as
soon as link state changes, but is an improvement over the current code
where linkwatch_event processing is always delayed, which prevents
transmissions on the device from being deactivated leading transmit
watchdog timer to time-out.
Release the RTNL lock before link state change and re-acquire after
the link state change to allow linkwatch_event to grab the RTNL lock
and run during the reset.

The intention was to have the GEO_TX_POWER_LIMIT command in FW version
36 as well, but not all 8000 family got this feature enabled. The
8000 family is the only one using version 36, so skip this version
entirely. If we try to send this command to the firmwares that do not
support it, we get a BAD_COMMAND response from the firmware.
