====================
DP83822 and DP83TC811 Fixes
Two fixes on net/phy/Kconfig for the TI ethernet PHYs.
First fixed the typo in the Kconfig for the DP83TC811 where it incorretly stated
that the support was for a DP83TC822 which does not exist.
Second fix was to update the DP83822 Kconfig entry to indicate support for the
DP83825 devices in the description and the prompt.

The commit cited below causes devlink to emit a warning if a type was
not set on a devlink port for longer than 30 seconds to "prevent
misbehavior of drivers". This proved to be problematic when
unregistering the backing netdev. The flow is always:
devlink_port_type_clear() // schedules the warning
unregister_netdev() // blocking
devlink_port_unregister() // cancels the warning
The call to unregister_netdev() can block for long periods of time for
various reasons: RTNL lock is contended, large amounts of configuration
to unroll following dismantle of the netdev, etc. This results in
devlink emitting a warning despite the driver behaving correctly.
In emulated environments (of future hardware) which are usually very
slow, the warning can also be emitted during port creation as more than
30 seconds can pass between the time the devlink port is registered and
when its type is set.
In addition, syzbot has hit this warning [1] 1974 times since 07/11/19
without being able to produce a reproducer. Probably because
reproduction depends on the load or other bugs (e.g., RTNL not being
released).
To prevent bogus warnings, increase the timeout to 1 hour.

Sven-Haegar reported looping on fib dumps when 255.255.255.255 route has
been added to a table. The looping is caused by the key rolling over from
FFFFFFFF to 0. When dumping a specific table only, we need a means to detect
when the table dump is done. The key and count saved to cb args are both 0
only at the start of the table dump. If key is 0 and count > 0, then we are
in the rollover case. Detect and return to avoid looping.
This only affects dumps of a specific table; for dumps of all tables
(the case prior to the change in the Fixes tag) inet_dump_fib moved
the entry counter to the next table and reset the cb args used by
fib_table_dump and fn_trie_dump_leaf, so the rollover ffffffff back
to 0 did not cause looping with the dumps.

When device loses sync mid way through a record - kernel
has to re-encrypt the part of the record which the device
already decrypted to be able to decrypt and authenticate
the record in its entirety.
The re-encryption piggy backs on the decryption routine,
but obviously because the partially decrypted record can't
be authenticated crypto API returns an error which is then
ignored by tls_device_reencrypt().
Commit 5c5ec6685806 ("net/tls: add TlsDecryptError stat")
added a statistic to count decryption errors, this statistic
can't be incremented when we see the expected re-encryption
error. Move the inc to the caller.

This patch fixes 2 issues in x25_connect():
1. It makes absolutely no sense to reset the neighbour and the
connection state after a (successful) nonblocking call of x25_connect.
This prevents any connection from being established, since the response
(call accept) cannot be processed.
2. Any further calls to x25_connect() while a call is pending should
simply return, instead of creating new Call Request (on different
logical channels).
This patch should also fix the "KASAN: null-ptr-deref Write in
x25_connect" and "BUG: unable to handle kernel NULL pointer dereference
in x25_connect" bugs reported by syzbot.

Currently MAC filters are not altered during a VF reset event. This may
lead to a stale filter when an administratively set MAC is forced by the
PF.
For an administratively set MAC the PF driver deletes the VFs filters,
overwrites the VFs MAC address and triggers a VF reset. However
the VF driver itself is not aware of the filter removal, which is what
the VF reset is for.
The VF reset queues all filters present in the VF driver to be re-added
to the PF filter list (including the filter for the now stale VF MAC
address) and triggers a VIRTCHNL_OP_GET_VF_RESOURCES event, which
provides the new MAC address to the VF.
When this happens i40e will complain and reject the stale MAC filter,
at least in the untrusted VF case.
i40e 0000:08:00.0: Setting MAC 3c:fa:fa:fa:fa:01 on VF 0
iavf 0000:08:02.0: Reset warning received from the PF
iavf 0000:08:02.0: Scheduling reset task
i40e 0000:08:00.0: Bring down and up the VF interface to make this change effective.
i40e 0000:08:00.0: VF attempting to override administratively set MAC address, bring down and up the VF interface to resume normal operation
i40e 0000:08:00.0: VF 0 failed opcode 10, retval: -1
iavf 0000:08:02.0: Failed to add MAC filter, error IAVF_ERR_NVM
To avoid re-adding the stale MAC filter it needs to be removed from the
VF driver's filter list before queuing the existing filters. Then during
the VIRTCHNL_OP_GET_VF_RESOURCES event the correct filter needs to be
added again, at which point the MAC address has been updated.
As a bonus this change makes bringing the VF down and up again
superfluous for the administratively set MAC case.

Currently in i40e_vc_disable_queues_msg() we are incorrectly
validating the virtchnl queue select bitmaps. The
virtchnl_queue_select rx_queues and tx_queue bitmap is being
compared against ICE_MAX_VF_QUEUES, but the problem is that
these bitmaps can have a value greater than I40E_MAX_VF_QUEUES.
Fix this by comparing the bitmaps against BIT(I40E_MAX_VF_QUEUES).
Also, add the function i40e_vc_validate_vqs_bitmaps() that checks to see
if both virtchnl_queue_select bitmaps are empty along with checking that
the bitmaps only have valid bits set. This function can then be used in
both the queue enable and disable flows.

it must be set to `true` upon creation, because wired devices do not

The current 'tipc_wait_for_connect()' function does a wait-loop for the
condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket
connecting has done. However, when the condition is met, it returns '0'
even in the case the connecting is actually failed, the socket state is
set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..).
This results in a wrong return code for the 'connect()' call from user,
making it believe that the connection is established and go ahead with
building, sending a message, etc. but finally failed e.g. '-EPIPE'.
This commit fixes the issue by changing the wait condition to the
'tipc_sk_connected(sk)', so the function will return '0' only when the
connection is really established. Otherwise, either the socket 'sk_err'
if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

When a socket is suddenly shutdown or released, it will reject all the
unreceived messages in its receive queue. This applies to a connected
socket too, whereas there is only one 'FIN' message required to be sent
back to its peer in this case.
In case there are many messages in the queue and/or some connections
with such messages are shutdown at the same time, the link layer will
easily get overflowed at the 'TIPC_SYSTEM_IMPORTANCE' backlog level
because of the message rejections. As a result, the link will be taken
down. Moreover, immediately when the link is re-established, the socket
layer can continue to reject the messages and the same issue happens...
The commit refactors the '__tipc_shutdown()' function to only send one
'FIN' in the situation mentioned above. For the connectionless case, it
is unavoidable but usually there is no rejections for such socket
messages because they are 'dest-droppable' by default.
In addition, the new code makes the other socket states clear
(e.g.'TIPC_LISTEN') and treats as a separate case to avoid misbehaving.

Use of eth_hdr() in tx path is error prone.
Many drivers call skb_reset_mac_header() before using it,
but others do not.
Commit 6d1ccff62780 ("net: reset mac header in dev_start_xmit()")
attempted to fix this generically, but commit d346a3fae3ff
("packet: introduce PACKET_QDISC_BYPASS socket option") brought
back the macvlan bug.
Lets add a new helper, so that tx paths no longer have
to call skb_reset_mac_header() only to get a pointer
to skb->data.
Hopefully we will be able to revert 6d1ccff62780
("net: reset mac header in dev_start_xmit()") and save few cycles
in transmit fast path.

Petr Machata says:
====================
When ungrafting from PRIO, replace child with FIFO
When a child Qdisc is removed from one of the PRIO Qdisc's bands, it is
replaced unconditionally by a NOOP qdisc. As a result, any traffic hitting
that band gets dropped. That is incorrect--no Qdisc was explicitly added
when PRIO was created, and after removal, none should have to be added
either.
In patch #2, this problem is fixed for PRIO by first attempting to create a
default Qdisc and only falling back to noop when that fails. This pattern
of attempting to create an invisible FIFO, using NOOP only as a fallback,
is also seen in some other Qdiscs.
The only driver currently offloading PRIO (and thus presumably the only one
impacted by this) is mlxsw. Therefore patch #1 extends mlxsw to handle the
replacement by an invisible FIFO gracefully.

The following patch will change PRIO to replace a removed Qdisc with an
invisible FIFO, instead of NOOP. mlxsw will see this replacement due to the
graft message that is generated. But because FIFO does not issue its own
REPLACE message, when the graft operation takes place, the Qdisc that mlxsw
tracks under the indicated band is still the old one. The child
handle (0:0) therefore does not match, and mlxsw rejects the graft
operation, which leads to an extack message:
Warning: Offloading graft operation failed.
Fix by ignoring the invisible children in the PRIO graft handler. The
DESTROY message of the removed Qdisc is going to follow shortly and handle
the removal.

As diagnosed by Florian :
If TCA_FQ_QUANTUM is set to 0x80000000, fq_deueue()
can loop forever in :
if (f->credit <= 0) {
f->credit += q->quantum;
goto begin;
}
... because f->credit is either 0 or -2147483648.
Let's limit TCA_FQ_QUANTUM to no more than 1 << 20 :
This max value should limit risks of breaking user setups
while fixing this bug.

There are few cases where the ndo_uninit() handler might be not
called if an error happens while device is initialized.
Since vlan_newlink() calls vlan_changelink() before
trying to register the netdevice, we need to make sure
vlan_dev_uninit() has been called at least once,
or we might leak allocated memory.
