[PATCH net v2 1/2] net: core: Specify skb_pad()/skb_put_padto() SKB freeing

Rename skb_pad() into __skb_pad() and make it take a third argument: free_on_error which controls whether kfree_skb() should be called or not, skb_pad() directly makes use of it and passes true to preserve its existing behavior. Do exactly the same thing with __skb_put_padto() and skb_put_padto().

The first call of skb_put_padto() will free up the SKB on error, but we return NULL which tells dsa_slave_xmit() that the original SKB should be freed so this would lead to a double free here. The second skb_put_padto() already frees the passed sk_buff reference upon error, so calling kfree_skb()

[PATCH v2] i40e/i40evf: fix out-of-bounds read of cpumask

When responding to an affinity hint we directly copied a cpumask value, intsead of using cpumask_copy. According to cpumask.h this is not correct because cpumask_t is only guaranteed to have enough space for the number of CPUs in the system, and may not be as big as we expect. Thus a direct copy

[PATCH] e1000: changed some expensive calls of udelay to usleep_range

Calls to udelay are not preemtable by userspace so userspace applications experience a large (~200us) latency when running on core 0. Instead usleep_range can be used to be more friendly to userspace since it is preemtable. This is due to udelay using busy-wait loops while
