      ptp: Add error handling for adjfine callback in ptp_clock_adjtime · 98337d7c
      Ajay Kaher authored 
      
ptp_clock_adjtime sets ptp->dialed_frequency even when adjfine
callback returns an error. This causes subsequent reads to return
an incorrect value.

Fix this by adding error check before ptp->dialed_frequency is set.

      tcp: populate XPS related fields of timewait sockets · 0a4cc4ac
      Eric Dumazet authored 
      
syzbot reported that netdev_core_pick_tx() was reading an uninitialized
field [1].

This is indeed hapening for timewait sockets after recent commits.

We can copy the original established socket sk_tx_queue_mapping
and sk_rx_queue_mapping fields, instead of adding more checks
in fast paths.

As a bonus, packets will use the same transmit queue than
prior ones, this potentially can avoid reordering.

====================
fix crash issue when setting MQPRIO for VFs

There is a crash issue when setting MQPRIO for ENETC VFs, the root casue
is that ENETC VFs don't like ENETC PFs, they don't have port registers,
so hw->port of VFs is NULL. However, this NULL pointer will be accessed
without any checks in enetc_mm_commit_preemptible_tcs() when configuring
MQPRIO for VFs. Therefore, two patches are added to fix this issue. The
first patch sets ENETC_SI_F_QBU flag only for SIs that support 802.1Qbu.
The second patch adds a check in enetc_change_preemptible_tcs() to ensure
that SIs that do not support 802.1Qbu do not configure preemptible TCs.

      net: enetc: Do not configure preemptible TCs if SIs do not support · b2420b8c
      Wei Fang authored 
      
Both ENETC PF and VF drivers share enetc_setup_tc_mqprio() to configure
MQPRIO. And enetc_setup_tc_mqprio() calls enetc_change_preemptible_tcs()
to configure preemptible TCs. However, only PF is able to configure
preemptible TCs. Because only PF has related registers, while VF does not
have these registers. So for VF, its hw->port pointer is NULL. Therefore,
VF will access an invalid pointer when accessing a non-existent register,
which will cause a crash issue. The simplified log is as follows.

In addition, some PFs also do not support configuring preemptible TCs,
such as eno1 and eno3 on LS1028A. It won't crash like it does for VFs,
but we should prevent these PFs from accessing these unimplemented
registers.

      net: enetc: read TSN capabilities from port register, not SI · 8e00072c
      Vladimir Oltean authored 
      
Configuring TSN (Qbv, Qbu, PSFP) capabilities requires access to port
registers, which are available to the PSI but not the VSI.

Yet, the SI port capability register 0 (PSICAPR0), exposed to both PSIs
and VSIs, presents the same capabilities to the VF as to the PF, thus
leading the VF driver into thinking it can configure these features.

In the case of ENETC_SI_F_QBU, having it set in the VF leads to a crash:

root@ls1028ardb:~# tc qdisc add dev eno0vf0 parent root handle 100: \
mqprio num_tc 4 map 0 0 1 1 2 2 3 3 queues 1@0 1@1 1@2 1@3 hw 1

while the other TSN features in the VF are harmless, because the
net_device_ops used for the VF driver do not expose entry points for
these other features.

These capability bits are in the process of being defeatured from the SI
registers. We should read them from the port capability register, where
they are also present, and which is naturally only exposed to the PF.

The change to blame (relevant for stable backports) is the one where
this started being a problem, aka when the kernel started to crash due
to the wrong capability seen by the VF driver.

 "Change the driver callback op domain_alloc_user() into two ops:
  domain_alloc_paging_flags() and domain_alloc_nesting() that better
  describe what the ops are expected to do.

  There will be per-driver cleanup based on this going into the next
