wireguard: device: use icmp_ndo_send helper

2020-02-13T22:19:00+00:00

Because wireguard is calling icmp from network device context, it should use the ndo helper so that the rate limiting applies correctly. This commit adds a small test to the wireguard test suite to ensure that the new functions continue doing the right thing in the context of wireguard. It does this by setting up a condition that will definately evoke an icmp error message from the driver, but along a nat'd path. Signed-off-by: Jason A. Donenfeld Signed-off-by: David S. Miller

2020-02-12T19:09:38+00:00

get_gdt_base() and get_idt_base() only return the base address of the descriptor tables. Soon we will need to get the size as well. Change the prototype of those functions so that they return the whole desc_ptr struct instead of the address field.
