      virtio-net: enable TSO/checksum offloads for Q-in-Q vlans · 2836b4f2
      Vlad Yasevich authored 
      Since virtio does not provide it's own ndo_features_check handler,
TSO, and now checksum offload, are disabled for stacked vlans.
Re-enable the support and let the host take care of it.  This
restores/improves Guest-to-Guest performance over Q-in-Q vlans.

      be2net: Fix offload features for Q-in-Q packets · cc6e9de6
      Vlad Yasevich authored 
      At least some of the be2net cards do not seem to be capabled
of performing checksum offload computions on Q-in-Q packets.
In these case, the recevied checksum on the remote is invalid
and TCP syn packets are dropped.

This patch adds a call to check disbled acceleration features
on Q-in-Q tagged traffic.

      vlan: Fix tcp checksum offloads in Q-in-Q vlans · 35d2f80b
      Vlad Yasevich authored 
      It appears that TCP checksum offloading has been broken for
Q-in-Q vlans.  The behavior was execerbated by the
series
    commit afb0bc97 ("Merge branch 'stacked_vlan_tso'")
that that enabled accleleration features on stacked vlans.

However, event without that series, it is possible to trigger
this issue.  It just requires a lot more specialized configuration.

The root cause is the interaction between how
netdev_intersect_features() works, the features actually set on
the vlan devices and HW having the ability to run checksum with
longer headers.

The issue starts when netdev_interesect_features() replaces
NETIF_F_HW_CSUM with a combination of NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM,
if the HW advertises IP|IPV6 specific checksums.  This happens
for tagged and multi-tagged packets.   However, HW that enables
IP|IPV6 checksum offloading doesn't gurantee that packets with
arbitrarily long headers can be checksummed.

This patch disables IP|IPV6 checksums on the packet for multi-tagged
packets.

      net: rtnetlink: bail out from rtnl_fdb_dump() on parse error · 0ff50e83
      Alexander Potapenko authored 
      rtnl_fdb_dump() failed to check the result of nlmsg_parse(), which led
to contents of |ifm| being uninitialized because nlh->nlmsglen was too
small to accommodate |ifm|. The uninitialized data may affect some
branches and result in unwanted effects, although kernel data doesn't
seem to leak to the userspace directly.

The bug has been detected with KMSAN and syzkaller.

For the record, here is the KMSAN report:

      net: fec: add post PHY reset delay DT property · 159a0760
      Quentin Schulz authored 
      Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.

If the DT property is not given, no delay is observed. Post reset delay
greater than 1000ms are invalid.

      sctp: set new_asoc temp when processing dupcookie · 7e062977
      Xin Long authored 
      After sctp changed to use transport hashtable, a transport would be
added into global hashtable when adding the peer to an asoc, then
the asoc can be got by searching the transport in the hashtbale.

The problem is when processing dupcookie in sctp_sf_do_5_2_4_dupcook,
a new asoc would be created. A peer with the same addr and port as
the one in the old asoc might be added into the new asoc, but fail
to be added into the hashtable, as they also belong to the same sk.

It causes that sctp's dupcookie processing can not really work.

Since the new asoc will be freed after copying it's information to
the old asoc, it's more like a temp asoc. So this patch is to fix
it by setting it as a temp asoc to avoid adding it's any transport
into the hashtable and also avoid allocing assoc_id.

An extra thing it has to do is to also alloc stream info for any
temp asoc, as sctp dupcookie process needs it to update old asoc.
But I don't think it would hurt something, as a temp asoc would
always be freed after finishing processing cookie echo packet.

      Since commit 3dbcc105 ("sctp: alloc stream info when initializing

So it's not correct to check !asoc->stream before updating stream
info when processing dupcookie, but would be better to check asoc
state instead.

      efi-pstore: Fix write/erase id tracking · c10e8031
      Kees Cook authored 
      Prior to the pstore interface refactoring, the "id" generated during
a backend pstore_write() was only retained by the internal pstore
inode tracking list. Additionally the "part" was ignored, so EFI
would encode this in the id. This corrects the misunderstandings
and correctly sets "id" during pstore_write(), and uses "part"
directly during pstore_erase().

None of these were actually specified as ARP targets, and the driver does
seem to clean up the mess okay, but it's rather noisy and confusing, leaks
values to userspace, and the 255.255.255.255 spew shows up even when debug
prints are disabled.

The fix: just zero out arp_target at init time.

While we're in here, init arp_all_targets_value in the right place.
