      net: dsa: b53: Set correct number of ports in the DSA struct · d12e1c46
      Rafał Miłecki authored 
      Setting DSA_MAX_PORTS caused DSA to call b53 callbacks (e.g.
b53_disable_port() during dsa_register_switch()) for invalid
(non-existent) ports. That made b53 modify unrelated registers and is
one of reasons for a broken BCM5301x support.

This problem exists for years but DSA_MAX_PORTS usage has changed few
times. It seems the most accurate to reference commit dropping
dsa_switch_alloc() in the Fixes tag.

      net: dsa: b53: Fix calculating number of switch ports · cdb067d3
      Rafał Miłecki authored 
      It isn't true that CPU port is always the last one. Switches BCM5301x
have 9 ports (port 6 being inactive) and they use port 5 as CPU by
default (depending on design some other may be CPU ports too).

A more reliable way of determining number of ports is to check for the
last set bit in the "enabled_ports" bitfield.

This fixes b53 internal state, it will allow providing accurate info to
the DSA and is required to fix BCM5301x support.

      net: hso: add failure handler for add_net_device · ecdc28de
      Ziyang Xuan authored 
      If the network devices connected to the system beyond
HSO_MAX_NET_DEVICES. add_net_device() in hso_create_net_device()
will be failed for the network_table is full. It will lead to
business failure which rely on network_table, for example,
hso_suspend() and hso_resume(). It will also lead to memory leak
because resource release process can not search the hso_device
object from network_table in hso_free_interface().

Add failure handler for add_net_device() in hso_create_net_device()
to solve the above problems.

I don't think we need to call flowi{4,6}_to_flowi() from these functions
because the first member of "struct flowi4" and "struct flowi6" is

  struct flowi_common __fl_common;

while the first member of "struct flowi" is

  union {
    struct flowi_common __fl_common;
    struct flowi4       ip4;
    struct flowi6       ip6;
    struct flowidn      dn;
  } u;

which should point to the same address without access to "struct flowi".

      Set fc_nlinfo in nh_create_ipv4, nh_create_ipv6 · 9aca491e
      Ryoga Saito authored 
      This patch fixes kernel NULL pointer dereference when creating nexthop
which is bound with SRv6 decapsulation. In the creation of nexthop,
__seg6_end_dt_vrf_build is called. __seg6_end_dt_vrf_build expects
fc_lninfo in fib6_config is set correctly, but it isn't set in
nh_create_ipv6, which causes kernel crash.

Here is steps to reproduce kernel crash:

1. modprobe vrf
2. ip -6 nexthop add encap seg6local action End.DT4 vrftable 1 dev eth0

We got the following message:

      Jan Hoffmann authored 
      Currently, outgoing packets larger than 1496 bytes are dropped when
tagged VLAN is used on a switch port.

Add the frame check sequence length to the value of the register
GSWIP_MAC_FLEN to fix this. This matches the lantiq_ppa vendor driver,
which uses a value consisting of 1518 bytes for the MAC frame, plus the
lengths of special tag and VLAN tags.

      net/sun3_82586: Fix return value of sun3_82586_probe() · 66abf5fb
      Geert Uytterhoeven authored 
      drivers/net/ethernet/i825xx/sun3_82586.c: In function ‘sun3_82586_probe’:
drivers/net/ethernet/i825xx/sun3_82586.c:317:9: warning: returning ‘struct net_device *’ from a function with return type ‘int’ makes integer from pointer without a cast [-Wint-conversion]
  317 |  return dev;
      |         ^~~

The return type of sun3_82586_probe() was changed, but one return value
was forgotten to be updated.

Fixes: e179d78e ("m68k: remove legacy probing")

 "There is a long-standing subtle destroy_workqueue() bug where a

Pull device mapper updates from Mike Snitzer:

 - Add DM infrastructure for IMA-based remote attestion. These changes
   are the basis for deploying DM-based storage in a "cloud" that must
   validate configurations end-users run to maintain trust. These DM
   changes allow supported DM targets' configurations to be measured via
   IMA. But the policy and enforcement (of which configurations are
   valid) is managed by something outside the kernel (e.g. Keylime).

 - Fix DM crypt scalability regression on systems with many cpus due to
   percpu_counter spinlock contention in crypt_page_alloc().

 - Use in_hardirq() instead of deprecated in_irq() in DM crypt.

 - Add event counters to DM writecache to allow users to further assess
   how the writecache is performing.

 - Various code cleanup in DM writecache's main IO mapping function.
