In case pci channel becomes offline the driver should not wait for PCI
reads during health dump and recovery flow. The driver has timeout for
each of these loops trying to read PCI, so it would fail anyway.
However, in case of recovery waiting till timeout may cause the pci
error_detected() callback fail to meet pci_dpc_recovered() wait timeout.

The mainline MTK ethernet driver suffers long time from rarly but
annoying tx queue timeouts. We think that this is caused by fixed
dma sizes hardcoded for all SoCs.
We suspect this problem arises from a low level of free TX DMADs,
the TX Ring alomost full.
The transmit timeout is caused by the Tx queue not waking up. The
Tx queue stops when the free counter is less than ring->thres, and
it will wake up once the free counter is greater than ring->thres.
If the CPU is too late to wake up the Tx queues, it may cause a
transmit timeout.
Therefore, we increased the TX and RX DMADs to improve this error
situation.
Use the dma-size implementation from SDK in a per SoC manner. In
difference to SDK we have no RSS feature yet, so all RX/TX sizes
should be raised from 512 to 2048 byte except fqdma on mt7988 to
avoid the tx timeout issue.

Jaroslav reports Dell's OMSA Systems Management Data Engine
expects NLM_DONE in a separate recvmsg(), both for rtnl_dump_ifinfo()
and inet_dump_ifaddr(). We already added a similar fix previously in
commit 460b0d33cf10 ("inet: bring NLM_DONE out to a separate recv() again")
Instead of modifying all the dump handlers, and making them look
different than modern for_each_netdev_dump()-based dump handlers -
put the workaround in rtnetlink code. This will also help us move
the custom rtnl-locking from af_netlink in the future (in net-next).
Note that this change is not touching rtnl_dump_all(). rtnl_dump_all()
is different kettle of fish and a potential problem. We now mix families
in a single recvmsg(), but NLM_DONE is not coalesced.

Like previous patch does in TCP, we need to adhere to RFC 1213:
"tcpCurrEstab OBJECT-TYPE
...
The number of TCP connections for which the current state
is either ESTABLISHED or CLOSE- WAIT."
So let's consider CLOSE-WAIT sockets.
The logic of counting
When we increment the counter?
a) Only if we change the state to ESTABLISHED.
When we decrement the counter?
a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT,
say, on the client side, changing from ESTABLISHED to FIN-WAIT-1.
b) if the socket leaves CLOSE-WAIT, say, on the server side, changing
from CLOSE-WAIT to LAST-ACK.

According to RFC 1213, we should also take CLOSE-WAIT sockets into
consideration:
"tcpCurrEstab OBJECT-TYPE

The number of TCP connections for which the current state
is either ESTABLISHED or CLOSE- WAIT."
After this, CurrEstab counter will display the total number of
ESTABLISHED and CLOSE-WAIT sockets.
The logic of counting
When we increment the counter?
a) if we change the state to ESTABLISHED.
b) if we change the state from SYN-RECEIVED to CLOSE-WAIT.
When we decrement the counter?
a) if the socket leaves ESTABLISHED and will never go into CLOSE-WAIT,
say, on the client side, changing from ESTABLISHED to FIN-WAIT-1.
b) if the socket leaves CLOSE-WAIT, say, on the server side, changing
from CLOSE-WAIT to LAST-ACK.
Please note: there are two chances that old state of socket can be changed
to CLOSE-WAIT in tcp_fin(). One is SYN-RECV, the other is ESTABLISHED.
So we have to take care of the former case.

Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address")
has recently been added to vxlan mainly in the context of source
address snooping/learning so that when it is enabled, an entry in the
FDB is not being created for an invalid address for the corresponding
tunnel endpoint.
Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in
that it passed through whichever macs were set in the L2 header. It
turns out that this change in behavior breaks setups, for example,
Cilium with netkit in L3 mode for Pods as well as tunnel mode has been
passing before the change in f58f45c1e5b9 for both vxlan and geneve.
After mentioned change it is only passing for geneve as in case of
vxlan packets are dropped due to vxlan_set_mac() returning false as
source and destination macs are zero which for E/W traffic via tunnel
is totally fine.
Fix it by only opting into the is_valid_ether_addr() check in
vxlan_set_mac() when in fact source address snooping/learning is
actually enabled in vxlan. This is done by moving the check into
vxlan_snoop(). With this change, the Cilium connectivity test suite
passes again for both tunnel flavors.

issue is the main phylib code no longer resets PHY at the very beginning.

A typical call trace for the above situation will start with one of the
following errors:
refcount_t: decrement hit 0; leaking memory.
refcount_t: underflow; use-after-free.
And will then have a trace like:

On reboot (or any attempt to remove the interface), the kernel gets
stuck in an infinite loop:
unregister_netdevice: waiting for ax0 to become free. Usage count = 0
This patch corrects these issues by ensuring that we call netdev_hold()
and ax25_dev_hold() for new connections in ax25_accept(). This makes the
logic leading to ax25_accept() match the logic for ax25_bind(): in both
cases we increment the refcount, which is ultimately decremented in
ax25_release().

When the following snippet is run, lockdep will report a deadlock[1].
/* Acquire all queues dim_locks */
for (i = 0; i < vi->max_queue_pairs; i++)
mutex_lock(&vi->rq[i].dim_lock);
There's no deadlock here because the vq locks are always taken
in the same order, but lockdep can not figure it out. So refactoring
the code to alleviate the problem.

When the dim worker is scheduled, if it no longer needs to issue
commands, dim may not be able to return to the working state later.
For example, the following single queue scenario:
1. The dim worker of rxq0 is scheduled, and the dim status is
changed to DIM_APPLY_NEW_PROFILE;
2. dim is disabled or parameters have not been modified;
3. virtnet_rx_dim_work exits directly;
Then, even if net_dim is invoked again, it cannot work because the
state is not restored to DIM_START_MEASURE.

rtlwifi relied on ~0 in order to ignore the default retry limits of

RTL8192DU has a lot of packet loss with the default limits from

Commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU")

The runtime issues that arose after merging it showed that there are code
paths involving sleeping functions, and removing those would need some
heavier driver rework.
Add some documentation about SRCU need to make sure that any future
developer do not miss some use cases if tempted to convert back again to
RCU.

This reverts commit f236464f1db7bea80075e6e31ac70dc6eb80547f
Commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU")
replaced SRCU with RCU, aiming to simplify RCU usage in the driver. No
documentation or commit history hinted about why SRCU has been preferred
in original design, so it has been assumed to be safe to do this
conversion.
Unfortunately, some static analyzers raised warnings, confirmed by runtime
checker, not long after the merge. At least three different issues arose
when switching to RCU:
- wilc_wlan_txq_filter_dup_tcp_ack is executed in a RCU read critical
section yet calls wait_for_completion_timeout
- wilc_wfi_init_mon_interface calls kmalloc and register_netdevice while
manipulating a vif retrieved from vif list
- set_channel sends command to chip (and so, also waits for a completion)
while holding a vif retrieved from vif list (so, in RCU read critical
section)
Some of those issues are not trivial to fix and would need bigger driver
rework. Fix those issues by reverting the SRCU to RCU conversion commit

Recent commit 0cfe71f45f42 ("netdev: add queue stats") added
a lot of useful stats, but only those immediately needed by virtio.
Presumably virtio does not support CHECKSUM_COMPLETE,
so statistic for that form of checksumming wasn't included.
Other drivers will definitely need it, in fact we expect it
to be needed in net-next soon (mlx5). So let's add the definition
of the counter for CHECKSUM_COMPLETE to uAPI in net already,
so that the counters are in a more natural order (all subsequent
counters have not been present in any released kernel, yet).

The following patchset contains Netfilter fixes for net:
Patch #1 syzbot reports that nf_reinject() could be called without
rcu_read_lock() when flushing pending packets at nfnetlink
queue removal, from Eric Dumazet.
Patch #2 flushes ipset list:set when canceling garbage collection to
reference to other lists to fix a race, from Jozsef Kadlecsik.
Patch #3 restores q-in-q matching with nft_payload by reverting
f6ae9f120dad ("netfilter: nft_payload: add C-VLAN support").
Patch #4 fixes vlan mangling in skbuff when vlan offload is present
in skbuff, without this patch nft_payload corrupts packets
in this case.
Patch #5 fixes possible nul-deref in tproxy no IP address is found in
netdevice, reported by syzbot and patch from Florian Westphal.
Patch #6 removes a superfluous restriction which prevents loose fib
lookups from input and forward hooks, from Eric Garver.
My assessment is that patches #1, #2 and #5 address possible kernel
crash, anything else in this batch fixes broken features.

The driver overrides the NUMA node id of the device regardless of
whether it knows its correct value (often setting it to -1 even though
the node id is advertised in 'struct device'). This can lead to
suboptimal configurations.
This patch fixes this behavior and makes the shared memory allocation
functions use the NUMA node id advertised by the underlying device.
