Linus Torvalds 23a46422c5 Networking fixes for 5.17-rc2, including fixes from netfilter and can.
Current release - new code bugs:
 
  - tcp: add a missing sk_defer_free_flush() in tcp_splice_read()
 
  - tcp: add a stub for sk_defer_free_flush(), fix CONFIG_INET=n
 
  - nf_tables: set last expression in register tracking area
 
  - nft_connlimit: fix memleak if nf_ct_netns_get() fails
 
  - mptcp: fix removing ids bitmap setting
 
  - bonding: use rcu_dereference_rtnl when getting active slave
 
  - fix three cases of sleep in atomic context in drivers: lan966x, gve
 
  - handful of build fixes for esoteric drivers after netdev->dev_addr
    was made const
 
 Previous releases - regressions:
 
  - revert "ipv6: Honor all IPv6 PIO Valid Lifetime values", it broke
    Linux compatibility with USGv6 tests
 
  - procfs: show net device bound packet types
 
  - ipv4: fix ip option filtering for locally generated fragments
 
  - phy: broadcom: hook up soft_reset for BCM54616S
 
 Previous releases - always broken:
 
  - ipv4: raw: lock the socket in raw_bind()
 
  - ipv4: decrease the use of shared IPID generator to decrease the
    chance of attackers guessing the values
 
  - procfs: fix cross-netns information leakage in /proc/net/ptype

Mohammad Athari Bin Ismail 0735e639f1 net: stmmac: skip only stmmac_ptp_register when resume from suspend
When resume from suspend, besides skipping PTP registration, it also
skipping PTP HW initialization. This could cause PTP clock not able to
operate properly when resume from suspend.

To fix this, only stmmac_ptp_register() is skipped when resume from
suspend.

continue to use GFP_KERNEL when allocating pages during setup.

GFP_KERNEL will allow blocking which allows it to succeed

The function lan966x_mac_wait_for_completion is used to poll the status
of the MAC table using the function readx_poll_timeout. The problem with

update the function to use readx_poll_timeout_atomic.

====================
pull-request: can 2022-01-24

The first patch updates the email address of Brian Silverman from his
former employer to his private address.

The next patch fixes DT bindings information for the tcan4x5x SPI CAN
driver.

The following patch targets the m_can driver and fixes the
introduction of FIFO bulk read support.

Another patch for the tcan4x5x driver, which fixes the max register
value for the regmap config.

The last patch for the flexcan driver marks the RX mailbox support for
the MCF5441X as support.

Marc Kleine-Budde f04aefd465 can: flexcan: mark RX via mailboxes as supported on MCF5441X
Most flexcan IP cores support 2 RX modes:
- FIFO
- mailbox

The flexcan IP core on the MCF5441X cannot receive CAN RTR messages
via mailboxes. However the mailbox mode is more performant. The commit

| 1c45f5778a ("can: flexcan: add ethtool support to change rx-rtr setting during runtime")

added support to switch from FIFO to mailbox mode on these cores.

After testing the mailbox mode on the MCF5441X by Angelo Dureghello,
this patch marks it (without RTR capability) as supported. Further the
IP core overview table is updated, that RTR reception via mailboxes is
not supported.

In order to optimize FIFO access, especially on m_can cores attached
to slow busses like SPI, in patch

| e39381770e ("can: m_can: Disable IRQs on FIFO bus errors")

bulk read/write support has been added to the m_can_fifo_{read,write}
functions.

That change leads to the tcan driver to call
regmap_bulk_{read,write}() with a length of 0 (for CAN frames with 0
data length). regmap treats this as an error:

| tcan4x5x spi1.0 tcan4x5x0: FIFO write returned -22

This patch fixes the problem by not calling the
cdev->ops->{read,write)_fifo() in case of a 0 length read/write.

ibmvnic_tasklet() continuously spins waiting for responses to all

during initialization of the vnic. However if there is a bug in the
VIOS and we do not receive a response to one or more queries the
tasklet ends up spinning continuously leading to hard lock ups.

If we fail to receive a message from the VIOS it is reasonable to
timeout the login attempt rather than spin indefinitely in the tasklet.

Sukadev Bhattiprolu 151b6a5c06 ibmvnic: init ->running_cap_crqs early
We use ->running_cap_crqs to determine when the ibmvnic_tasklet() should
send out the next protocol message type. i.e when we get back responses
to all our QUERY_CAPABILITY CRQs we send out REQUEST_CAPABILITY crqs.
Similiary, when we get responses to all the REQUEST_CAPABILITY crqs, we
send out the QUERY_IP_OFFLOAD CRQ.

We currently increment ->running_cap_crqs as we send out each CRQ and
have the ibmvnic_tasklet() send out the next message type, when this
running_cap_crqs count drops to 0.

This assumes that all the CRQs of the current type were sent out before
the count drops to 0. However it is possible that we send out say 6 CRQs,
get preempted and receive all the 6 responses before we send out the
remaining CRQs. This can result in ->running_cap_crqs count dropping to
zero before all messages of the current type were sent and we end up
sending the next protocol message too early.

Instead initialize the ->running_cap_crqs upfront so the tasklet will
only send the next protocol message after all responses are received.

Use the cap_reqs local variable to also detect any discrepancy (either
now or in future) in the number of capability requests we actually send.

Currently only send_query_cap() is affected by this behavior (of sending
next message early) since it is called from the worker thread (during
reset) and from application thread (during ->ndo_open()) and they can be
preempted. send_request_cap() is only called from the tasklet  which
processes CRQ responses sequentially, is not be affected.  But to
maintain the existing symmtery with send_query_capability() we update
send_request_capability() also.

Sukadev Bhattiprolu db9f0e8bf7 ibmvnic: Allow extra failures before disabling
If auto-priority-failover (APF) is enabled and there are at least two
backing devices of different priorities, some resets like fail-over,
change-param etc can cause at least two back to back failovers. (Failover
from high priority backing device to lower priority one and then back
to the higher priority one if that is still functional).

Depending on the timimg of the two failovers it is possible to trigger
a "hard" reset and for the hard reset to fail due to failovers. When this
occurs, the driver assumes that the network is unstable and disables the
VNIC for a 60-second "settling time". This in turn can cause the ethtool
command to fail with "No such device" while the vnic automatically recovers
a little while later.

Given that it's possible to have two back to back failures, allow for extra
failures before disabling the vnic for the settling time.
