      bonding: Add vlan tx offload to hw_enc_features · eab1f2dd
      YueHaibing authored 
      [ Upstream commit d595b03d ]

As commit 30d8177e ("bonding: Always enable vlan tx offload")
said, we should always enable bonding's vlan tx offload, pass the
vlan packets to the slave devices with vlan tci, let them to handle
vlan implementation.

Now if encapsulation protocols like VXLAN is used, skb->encapsulation
may be set, then the packet is passed to vlan device which based on
bonding device. However in netif_skb_features(), the check of
hw_enc_features:

	 if (skb->encapsulation)
                 features &= dev->hw_enc_features;

clears NETIF_F_HW_VLAN_CTAG_TX/NETIF_F_HW_VLAN_STAG_TX. This results
in same issue in commit 30d8177e like this:

vlan_dev_hard_start_xmit
  -->dev_queue_xmit
    -->validate_xmit_skb
      -->netif_skb_features //NETIF_F_HW_VLAN_CTAG_TX is cleared
      -->validate_xmit_vlan
        -->__vlan_hwaccel_push_inside //skb->tci is cleared
...
 --> bond_start_xmit
   --> bond_xmit_hash //BOND_XMIT_POLICY_ENCAP34
     --> __skb_flow_dissect // nhoff point to IP header
        -->  case htons(ETH_P_8021Q)
             // skb_vlan_tag_present is false, so
             vlan = __skb_header_pointer(skb, nhoff, sizeof(_vlan),
             //vlan point to ip header wrongly

      net/mlx5e: Use flow keys dissector to parse packets for ARFS · 4aa2734c
      Maxim Mikityanskiy authored 
      [ Upstream commit 405b93eb ]

The current ARFS code relies on certain fields to be set in the SKB
(e.g. transport_header) and extracts IP addresses and ports by custom
code that parses the packet. The necessary SKB fields, however, are not
always set at that point, which leads to an out-of-bounds access. Use
skb_flow_dissect_flow_keys() to get the necessary information reliably,
fix the out-of-bounds access and reuse the code.

      net/packet: fix race in tpacket_snd() · 7876df05
      Eric Dumazet authored 
      [ Upstream commit 32d3182c ]

packet_sendmsg() checks tx_ring.pg_vec to decide
if it must call tpacket_snd().

Problem is that the check is lockless, meaning another thread
can issue a concurrent setsockopt(PACKET_TX_RING ) to flip
tx_ring.pg_vec back to NULL.

Given that tpacket_snd() grabs pg_vec_lock mutex, we can
perform the check again to solve the race.

      bnx2x: Fix VF's VLAN reconfiguration in reload. · f7be8969
      Manish Chopra authored 
      [ Upstream commit 4a4d2d37 ]

Commit 04f05230 ("bnx2x: Remove configured vlans as
part of unload sequence."), introduced a regression in driver
that as a part of VF's reload flow, VLANs created on the VF
doesn't get re-configured in hardware as vlan metadata/info
was not getting cleared for the VFs which causes vlan PING to stop.

This patch clears the vlan metadata/info so that VLANs gets
re-configured back in the hardware in VF's reload flow and
PING/traffic continues for VLANs created over the VFs.

      netfilter: conntrack: Use consistent ct id hash calculation · 62b0863e
      Dirk Morris authored 
      commit 656c8e9c upstream.

Change ct id hash calculation to only use invariants.

Currently the ct id hash calculation is based on some fields that can
change in the lifetime on a conntrack entry in some corner cases. The
current hash uses the whole tuple which contains an hlist pointer which
will change when the conntrack is placed on the dying list resulting in
a ct id change.

This patch also removes the reply-side tuple and extension pointer from
the hash calculation so that the ct id will will not change from
initialization until confirmation.

      bpf: fix bpf_jit_limit knob for PAGE_SIZE >= 64K · 6c1dc8f9
      Daniel Borkmann authored 
      [ Upstream commit fdadd049 ]

Michael and Sandipan report:

  Commit ede95a63 introduced a bpf_jit_limit tuneable to limit BPF
  JIT allocations. At compile time it defaults to PAGE_SIZE * 40000,
  and is adjusted again at init time if MODULES_VADDR is defined.

  For ppc64 kernels, MODULES_VADDR isn't defined, so we're stuck with
  the compile-time default at boot-time, which is 0x9c400000 when
  using 64K page size. This overflows the signed 32-bit bpf_jit_limit
  value:

  root@ubuntu:/tmp# cat /proc/sys/net/core/bpf_jit_limit
  -1673527296

  and can cause various unexpected failures throughout the network
  stack. In one case `strace dhclient eth0` reported:

  setsockopt(5, SOL_SOCKET, SO_ATTACH_FILTER, {len=11, filter=0x105dd27f8},
             16) = -1 ENOTSUPP (Unknown error 524)

  and similar failures can be seen with tools like tcpdump. This doesn't
  always reproduce however, and I'm not sure why. The more consistent
  failure I've seen is an Ubuntu 18.04 KVM guest booted on a POWER9
  host would time out on systemd/netplan configuring a virtio-net NIC
  with no noticeable errors in the logs.

Given this and also given that in near future some architectures like
arm64 will have a custom area for BPF JIT image allocations we should
get rid of the BPF_JIT_LIMIT_DEFAULT fallback / default entirely. For
4.21, we have an overridable bpf_jit_alloc_exec(), bpf_jit_free_exec()
so therefore add another overridable bpf_jit_alloc_exec_limit() helper
function which returns the possible size of the memory area for deriving
the default heuristic in bpf_jit_charge_init().

Like bpf_jit_alloc_exec() and bpf_jit_free_exec(), the new
bpf_jit_alloc_exec_limit() assumes that module_alloc() is the default
JIT memory provider, and therefore in case archs implement their custom
module_alloc() we use MODULES_{END,_VADDR} for limits and otherwise for
vmalloc_exec() cases like on ppc64 we use VMALLOC_{END,_START}.

Additionally, for archs supporting large page sizes, we should change
the sysctl to be handled as long to not run into sysctl restrictions
in future.

      asm-generic: fix -Wtype-limits compiler warnings · 912420e5

Commit d66acc39 ("bitops: Optimise get_order()") introduced a
compilation warning because "rx_frag_size" is an "ushort" while
PAGE_SHIFT here is 16.

The commit changed the get_order() to be a multi-line macro where
compilers insist to check all statements in the macro even when
__builtin_constant_p(rx_frag_size) will return false as "rx_frag_size"
is a module parameter.

      USB: serial: option: Add Motorola modem UARTs · 765d9fe3
      Tony Lindgren authored 
      commit 6caf0be4 upstream.

On Motorola Mapphone devices such as Droid 4 there are five USB ports
that do not use the same layout as Gobi 1K/2K/etc devices listed in
qcserial.c. So we should use qcaux.c or option.c as noted by
Dan Williams <dan.j.williams@intel.com>.

As the Motorola USB serial ports have an interrupt endpoint as shown
with lsusb -v, we should use option.c instead of qcaux.c as pointed out
by Johan Hovold <johan@kernel.org>.

The ff/ff/ff interfaces seem to always be UARTs on Motorola devices.
For the other interfaces, class 0x0a (CDC Data) should not in general
be added as they are typically part of a multi-interface function as
noted earlier by Bjørn Mork <bjorn@mork.no>.

However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a
class is only used for flashing the modem firmware, and there are no
other interfaces. So I've added that too with more details below as it
works just fine.

The ttyUSB ports on Droid 4 are:

ttyUSB0 DIAG, CQDM-capable
ttyUSB1 MUX or NMEA, no response
ttyUSB2 MUX or NMEA, no response
ttyUSB3 TCMD
ttyUSB4 AT-capable

The ttyUSB0 is detected as QCDM capable by ModemManager. I think
it's only used for debugging with ModemManager --debug for sending
custom AT commands though. ModemManager already can manage data
connection using the USB QMI ports that are already handled by the
qmi_wwan.c driver.

To enable the MUX or NMEA ports, it seems that something needs to be
done additionally to enable them, maybe via the DIAG or TCMD port.
It might be just a NVRAM setting somewhere, but I have no idea what
NVRAM settings may need changing for that.

The TCMD port seems to be a Motorola custom protocol for testing
the modem and to configure it's NVRAM and seems to work just fine
based on a quick test with a minimal tcmdrw tool I wrote.

The voice modem AT-capable port seems to provide only partial
support, and no PM support compared to the TS 27.010 based UART
wired directly to the modem.

The UARTs added with this change are the same product IDs as the
Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't
have any mdm9600 based devices, so I have only tested these on
mdm6600 based droid 4.

Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android
Linux kernel driver moto_flashqsc.c just seems to change the
port->bulk_out_size to 8K from the default. And is only used for
flashing the modem firmware it seems.

I've verified that flashing the modem with signed firmware works just
fine with the option driver after manually toggling the GPIO pins, so
I've added droid 4 modem flashing mode to the option driver. I've not
added the other devices listed in moto_flashqsc.c in case they really
need different port->bulk_out_size. Those can be added as they get
tested to work for flashing the modem.

After this patch the output of /sys/kernel/debug/usb/devices has
the following for normal 22b8:2a70 mode including the related qmi_wwan
interfaces:
