Virtio-net devices negotiate LRO support with the host.
Display the initially negotiated state with ethtool -k.
Also allow configuring it with ethtool -K, reusing the existing
virtnet_set_guest_offloads helper that configures LRO for XDP.
This is conditional on VIRTIO_NET_F_CTRL_GUEST_OFFLOADS.
Virtio-net negotiates TSO4 and TSO6 separately, but ethtool does not
distinguish between the two. Display LRO as on only if any offload
is active.
RTNL is held while calling virtnet_set_features, same as on the path
from virtnet_xdp_set.
Changes v1 -> v2
- allow ethtool config (-K) only if VIRTIO_NET_F_CTRL_GUEST_OFFLOADS
- show LRO as enabled if any LRO variant is enabled
- do not allow configuration while XDP is active
- differentiate current features from the capable set, to restore
on XDP down only those features that were active on XDP up
- move test out of VIRTIO_NET_F_CSUM/TSO branch, which is tx only

pull-request: bpf-next 2018-12-21
The following pull-request contains BPF updates for your *net-next* tree.
There is a merge conflict in test_verifier.c. Result looks as follows:

[...]
{
"jset: range",
.insns = {
[...]
},
.prog_type = BPF_PROG_TYPE_SOCKET_FILTER,
.result_unpriv = ACCEPT,
.result = ACCEPT,
},
The main changes are:
1) Various BTF related improvements in order to get line info
working. Meaning, verifier will now annotate the corresponding
BPF C code to the error log, from Martin and Yonghong.
2) Implement support for raw BPF tracepoints in modules, from Matt.
3) Add several improvements to verifier state logic, namely speeding
up stacksafe check, optimizations for stack state equivalence
test and safety checks for liveness analysis, from Alexei.
4) Teach verifier to make use of BPF_JSET instruction, add several
test cases to kselftests and remove nfp specific JSET optimization
now that verifier has awareness, from Jakub.
5) Improve BPF verifier's slot_type marking logic in order to
allow more stack slot sharing, from Jiong.
6) Add sk_msg->size member for context access and add set of fixes
and improvements to make sock_map with kTLS usable with openssl
based applications, from John.
7) Several cleanups and documentation updates in bpftool as well as
auto-mount of tracefs for "bpftool prog tracelog" command,
from Quentin.
8) Include sub-program tags from now on in bpf_prog_info in order to
have a reliable way for user space to get all tags of the program
e.g. needed for kallsyms correlation, from Song.
9) Add BTF annotations for cgroup_local_storage BPF maps and
implement bpf fs pretty print support, from Roman.
10) Fix bpftool in order to allow for cross-compilation, from Ivan.
11) Update of bpftool license to GPLv2-only + BSD-2-Clause in order
to be compatible with libbfd and allow for Debian packaging,
from Jakub.
12) Remove an obsolete prog->aux sanitation in dump and get rid of
version check for prog load, from Daniel.
13) Fix a memory leak in libbpf's line info handling, from Prashant.
14) Fix cpumap's frame alignment for build_skb() so that skb_shared_info
does not get unaligned, from Jesper.
15) Fix test_progs kselftest to work with older compilers which are less
smart in optimizing (and thus throwing build error), from Stanislav.
16) Cleanup and simplify AF_XDP socket teardown, from Björn.
17) Fix sk lookup in BPF kselftest's test_sock_addr with regards
to netns_id argument, from Andrey.

Extract "Protocol" field decompression code from transport protocols to
PPP generic layer, where it actually belongs. As a consequence, this
patch fixes incorrect place of PFC decompression in L2TP driver (when
it's not PPPOX_BOUND) and also enables this decompression for other
protocols, like PPPoE.
Protocol field decompression also happens in PPP Multilink Protocol
code and in PPP compression protocols implementations (bsd, deflate,
mppe). It looks like there is no easy way to get rid of that, so it was
decided to leave it as is, but provide those cases with appropriate
comments instead.
Changes in v2:
- Fix the order of checking skb data room and proto decompression
- Remove "inline" keyword from ppp_decompress_proto()
- Don't split line before function name
- Prefix ppp_decompress_proto() function with "__"
- Add ppp_decompress_proto() function with skb data room checks
- Add description for introduced functions
- Fix comments (as per review on mailing list)

This is because when populating Driver Map using firmware raid map, all
non-existing VDs set their ldTgtIdToLd to 0xff, so it can be skipped later.
From drivers/scsi/megaraid/megaraid_sas_base.c ,
memset(instance->ld_ids, 0xff, MEGASAS_MAX_LD_IDS);
From drivers/scsi/megaraid/megaraid_sas_fp.c ,
/* For non existing VDs, iterate to next VD*/
if (ld >= (MAX_LOGICAL_DRIVES_EXT - 1))
continue;
However, there are a few places that failed to skip those non-existing VDs
due to off-by-one errors. Then, those 0xff leaked into MR_LdRaidGet(0xff,
map) and triggered the out-of-bound accesses.

When doing indirect access in the Ocelot chip, a command is setup,
issued and then we need to poll until the result is ready. The polling
timeout is specified in milliseconds in the datasheet and not in
register access attempts.
It is not a bug on the currently supported platform, but we observed
that the code does not work properly on other platforms that we want to
support as the timing requirements there are different.

Port partitioning is done by enabling UNICAST_VLAN_BOUNDARY and changing
the default port membership of 0x7f to other values such that there is
no communication between ports. In KSZ9477 the member for port 1 is
0x41; port 2, 0x42; port 3, 0x44; port 4, 0x48; port 5, 0x50; and port 7,
0x60. Port 6 is the host port.
Setting a zero value can be used to stop port from receiving.
However, when UNICAST_VLAN_BOUNDARY is disabled and the unicast addresses
are already learned in the dynamic MAC table, setting zero still allows
devices connected to those ports to communicate. This does not apply to
multicast and broadcast addresses though. To prevent these leaks and
make the function of port membership consistent UNICAST_VLAN_BOUNDARY
should never be disabled.
Note that UNICAST_VLAN_BOUNDARY is enabled by default in KSZ9477.

There is no need to abuse VID 1 anymore and we can instead use VID 4095
as the default VLAN, which will be configured on the port throughout its
lifetime.
The OVS join / leave functions are changed to enable VIDs 1-4094
(inclusive) instead of 2-4095. This because VID 4095 is now the default
VLAN instead of 1.

VLAN entries on a port can be associated with either a bridge VLAN or a
router port. Before the VLAN entry is destroyed these associations need
to be cleaned up.
Currently, this is always invoked from the function which destroys the
VLAN entry, but next patch is going to skip the destruction of the
default entry when a port in unlinked from a LAG.
The above does not mean that the associations should not be cleaned up,
so add a helper that will be invoked from both call sites.

In the latter case, when moving to the new default VLAN, there will not
be a need to destroy the default VLAN entry.
Therefore, add an argument that allows to control whether the default
port VLAN should be destroyed or not. Currently it is always set to
'true'.

Currently, the driver does not set the port's PVID when initializing a
new port. This is because the driver is using VID 1 as PVID which is the
firmware default.
Subsequent patches are going to change the PVID the driver is setting
when initializing a new port.
Prepare for that by explicitly setting the port's PVID.

In symmetric routing, the only two members in the VLAN corresponding to
the L3 VNI are the router port and the VXLAN tunnel.
In case the VXLAN device is already enslaved to the bridge and only
later the VLAN interface is configured, the tunnel will not be
offloaded.
The reason for this is that when the router interface (RIF)
corresponding to the VLAN interface is configured, it calls the core
fid_get() API which does not check if NVE should be enabled on the FID.
Instead, call into the bridge code which will check if NVE should be
enabled on the FID.
This effectively means that the same code path is used to retrieve a FID
when either a local port or a router port joins the FID.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2018-12-20
This series contains updates to e100, igb, ixgbe, i40e and ice drivers.
I replaced spinlocks for mutex locks to reduce the latency on CPU0 for
igb when updating the statistics. This work was based off a patch
provided by Jan Jablonsky, which was against an older version of the igb
driver.
Jesus adjusts the receive packet buffer size from 32K to 30K when
running in QAV mode, to stay within 60K for total packet buffer size for
igb.
Vinicius adds igb kernel documentation regarding the CBS algorithm and
its implementation in the i210 family of NICs.
YueHaibing from Huawei fixed the e100 driver that was potentially
passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL()
instead.
Konstantin Khorenko fixes i40e where we were not setting up the
neigh_priv_len in our net_device, which caused the driver to read beyond
the neighbor entry allocated memory.
Miroslav Lichvar extends the PTP gettime() to read the system clock by
adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e.
Young Xiao fixed the ice driver to only enable NAPI on q_vectors that
actually have transmit and receive rings.
Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the
NIC does not wake up when a cable is plugged in. This was due to the
driver not setting PME during runtime suspend.
Stephen Douthit enables the ixgbe driver allow DSA devices to use the
MII interface to talk to switches.

Add a helper to zero fill fields before copying data to
UVERBS_ATTR_STRUCT.
As UVERBS_ATTR_STRUCT can be used as an extensible struct, we want to make
sure that if the user supplies us with a struct that has new fields that
we are not aware of, we return them zeroed to the user.
This helper should be used when using UVERBS_ATTR_STRUCT for an extendable
data structure and there is a need to make sure that extended members of
the struct, that the kernel doesn't handle, are returned zeroed to the
user. This is needed due to the fact that UVERBS_ATTR_STRUCT allows
non-zero values for members after 'last' member.

During testing the command format was changed to close a security
hole. Revise the driver to use the command format that will actually be
supported in GA firmware.
Both the UMEM and UCTX are intended only for use by the kernel and cannot
be executed using a general command.
Since the UMEM and CTX are not part of the general object the caps bits
were moved to be some log_xxx location in the general HCA caps.
The firmware code was adapted as well to match the above.

I210 ethernet card doesn't wakeup when a cable gets plugged. It's
because its PME is not set.
Since commit 42eca2302146 ("PCI: Don't touch card regs after runtime
suspend D3"), if the PCI state is saved, pci_pm_runtime_suspend() stops
calling pci_finish_runtime_suspend(), which enables the PCI PME.
To fix the issue, let's not to save PCI states when it's runtime
suspend, to let the PCI subsystem enables PME.

tbl->entry_size + dev->neigh_priv_len
