Calling mrp_request_leave() after mrp_request_join(), the attr->state
is set to MRP_APPLICANT_VO, mrp_attr_destroy() won't be called in last
TX event in mrp_uninit_applicant(), the attr of applicant will be leaked.
To fix this leak, iterate and free each attr of applicant before rerturning
from mrp_uninit_applicant().

[ Upstream commit 0dbffbb5335a1e3aa6855e4ee317e25e669dd302 ]

sk_ll_usec is read locklessly from sk_can_busy_loop()
while another thread can change its value in sock_setsockopt()

This is correct but needs annotations.

[ Upstream commit 1d11fa231cabeae09a95cb3e4cf1d9dd34e00f08 ]

The doc draft-stewart-tsvwg-sctp-ipv4-00 that restricts 198 addresses
was never published. These addresses as private addresses should be
allowed to use in SCTP.

As Michael Tuexen suggested, this patch is to move 198 addresses from
unusable to private scope.

[ Upstream commit 5796015fa968a3349027a27dcd04c71d95c53ba5 ]

When TEE target mirrors traffic to another interface, sk_buff may
not have enough headroom to be processed correctly.
ip_finish_output2() detect this situation for ipv4 and allocates
new skb with enogh headroom. However ipv6 lacks this logic in
ip_finish_output2 and it leads to skb_under_panic:
