virtio_net_hdr_to_skb checks gso_type, but it does not verify that this
type correctly describes the actual packet. Segmentation happens based
on packet contents. So a packet was crafted to enter sctp gso, even
though no such gso_type exists. This issue is not specific to sctp.

The first 3 patches take care of array map offload, similarly to

Arraymap was not converted to use bpf_map_init_from_attr()

syzkaller generated a BPF proglet and triggered a warning with
the following:
0: (b7) r0 = 0
1: (d5) if r0 s<= 0x0 goto pc+0

Yes, it can.
These counters are incremented in netif_carrier_on() /
netif_carrier_off(). They are not always called in pairs and they can
be called multiple times for the same event. The phylib will c

The Time Based Scheduler (TBS) queueing discipline allows precise
control of the transmission time of packets.
The syntax is:

Validate gso_type of untrusted SKB_GSO_DODGY packets during
segmentation.
Untrusted user packets are limited to a small set of gso types in
virtio_net_hdr_to_skb. But segmentation occurs on packet contents.
Syzkaller was able to enter gso callbacks that are not hardened
