Pass information to the match offload on whether or not the repr is the
ingress or egress dev. Only accept tunnel matches if repr is the egress
dev.

This means rules such as the following are successfully offloaded:
tc .. add dev vxlan0 .. enc_dst_port 4789 .. action redirect dev nfp_p0

While rules such as the following are rejected:
tc .. add dev nfp_p0 .. enc_dst_port 4789 .. action redirect dev vxlan0

Also reject non tunnel flows that are offloaded to an egress dev.
Non tunnel matches assume that the offload dev is the ingress port and
offload a match accordingly.

Hardware has no notion of new or last mask id, instead it makes use of the
message type (i.e. add flow or del flow) in combination with a single bit
in metadata flags to determine when to add or delete a mask id. Previously
we made use of the new or last flags to indicate that a new mask should be
allocated or deallocated, respectively. This incorrect behaviour is fixed
by making use single bit in metadata flags to indicate mask allocation or

Alexandar Potapenko while testing the kernel with KMSAN and syzkaller
discovered that in some configurations sctp would leak 4 bytes of
kernel stack.

Working with his reproducer I discovered that those 4 bytes that
are leaked is the scope id of an ipv6 address returned by recvmsg.

With a little code inspection and a shrewd guess I discovered that
sctp_inet6_skb_msgname only initializes the scope_id field for link
local ipv6 addresses to the interface index the link local address
pertains to instead of initializing the scope_id field for all ipv6
addresses.

That is almost reasonable as scope_id's are meaniningful only for link
local addresses.  Set the scope_id in all other cases to 0 which is
not a valid interface index to make it clear there is nothing useful
in the scope_id field.

There should be no danger of breaking userspace as the stack leak
guaranteed that previously meaningless random data was being returned.

The socket level flow control is based on the assumption that incoming
buffers meet the condition (skb->truesize / roundup(skb->len) <= 4),
where the latter value is rounded off upwards to the nearest 1k number.
This does empirically hold true for the device drivers we know, but we
cannot trust that it will always be so, e.g., in a system with jumbo
frames and very small packets.

We now introduce a check for this condition at packet arrival, and if
we find it to be false, we copy the packet to a new, smaller buffer,
where the condition will be true. We expect this to affect only a small
fraction of all incoming packets, if at all.

Now CPSW driver configures min eth packet size to 60 octets (ETH_ZLEN)
which works in most of cases, but when port VLAN is configured on some
switch port, it also can be configured to force all egress packets to be
VLAN untagged. And in this case, CPSW driver will pad small packets to 60
octets, but final packet size on port egress can became less than 60 octets
due to VLAN tag removal and packet will be dropped.

Hence, fix it by accounting VLAN header in CPSW min eth packet size. While
here, use proper defines for CPSW_MAX_PACKET_SIZE also, instead of open
coding.

The IPv6 Segment Routing Header (SRH) format has been updated (revision 6
of the SRH ietf draft). The update includes the following SRH fields:

(1) The "First Segment" field changed to be "Last Entry" which contains
the index, in the Segment List, of the last element of the Segment List.

(2) The 16 bit "reserved" field now is used as a "tag" which tags a packet
as part of a class or group of packets, e.g.,packets sharing the same
set of properties.

This patch updates the struct ipv6_sr_hdr, so it complies with the updated
SRH draft. The 16 bit "reserved" field is changed to be "tag", In addition
a comment is added to the "first_segment" field, showing that it represents
the "Last Entry" field of the SRH.

rndis_filter_device_add() is called both from netvsc_probe() when we
initially create the device and from set channels/mtu/ringparam
routines where we basically remove the device and add it back.

hw_features is reset in rndis_filter_device_add() and filled with
host data. However, we lose all additional flags which are set outside
of the driver, e.g. register_netdevice() adds NETIF_F_SOFT_FEATURES and
many others.

Unfortunately, calls to rndis_{query_hwcaps(), _set_offload_params()}
calls cannot be avoided on every RNDIS reset: host expects us to set
required features explicitly. Moreover, in theory hardware capabilities
can change and we need to reflect the change in hw_features.

Reset net->hw_features bits according to host data in
rndis_netdev_set_hwcaps(), clear corresponding feature bits
from net->features in case some features went missing (will never happen
in real life I guess but let's be consistent).

According to the description, first argument of genlmsg_nlhdr() points to
what genlmsg_put() returns, i.e. beginning of user header. Therefore we
should only subtract size of genetlink header and netlink message header,
not user header.

This also means we don't need to pass the pointer to genetlink family and
the same is true for genl_dump_check_consistent() which is the only caller
of genlmsg_nlhdr(). (Note that at the moment, these functions are only
used for families which do not have user header so that they are not
affected.)

even without duplicated stream no, this value is far greater than the

Commit dfcb9f4f ("sctp: deny peeloff operation on asocs with threads

checking waitqueue_active(&asoc->wait) in sctp_do_peeloff().

But it actually doesn't work, as even if waitqueue_active returns false
the waiting sndbuf thread may still not yet hold sk lock. After asoc is
peeled off, sk is not asoc->base.sk any more, then to hold the old sk
lock couldn't make assoc safe to access.

This patch is to fix this by changing to hold the new sk lock if sk is
not asoc->base.sk, meanwhile, also set the sk in sctp_sendmsg with the
new sk.

With this fix, there is no more race between peeloff and waitbuf, the
check 'waitqueue_active' in sctp_do_peeloff can be removed.

Now in sctp_sendmsg sctp_wait_for_sndbuf could schedule out without
holding sock sk. It means the current asoc can be freed elsewhere,
like when receiving an abort packet.

If the asoc is just created in sctp_sendmsg and sctp_wait_for_sndbuf
returns err, the asoc will be freed again due to new_asoc is not nil.
An use-after-free issue would be triggered by this.

This patch is to fix it by setting new_asoc with nil if the asoc is
already dead when cpu schedules back, so that it will not be freed
again in sctp_sendmsg.

Pull IPMI updates from Corey Minyard:
 "This is a fairly large rework of the IPMI code, along with a bunch of
  smaller fixes. The major changes have been in the next tree for a
  couple of months, so they should be good to do in.

   - Some users had IPMI systems where the GUID of the IPMI controller
     could change. So rescanning of the GUID was added. The naming of
     some sysfs things was dependent on the GUID, however, so this
     resulted in the sysfs interface code in IPMI changing to remove
     that dependency and name the IPMI BMCs like other sysfs devices.

   - The ipmi_si_intf.c code was fairly bloated with all the different
     discovery methods (PCI, ACPI, SMBIOS, OF, platform, module
     parameters, hot add). The structure of how the interfaces were
     added was redone to make them more modular, then the individual
     methods were pulled out into their own files"

  then I will probably send them through by the end of the week just to
  get them out of the way.
