sock: set sk_err to ee_errno on dequeue from errq
When setting sk_err, set it to ee_errno, not ee_origin. Commit f5f99309fa74 ("sock: do not set sk_err in sock_dequeue_err_skb") disabled updating sk_err on errq dequeue, which is correct for most error types (origins): - sk->sk_err = err; Commit 38b257938ac6 ("sock: reset sk_err when the error queue is empty") reenabled the behavior for IMCP origins, which do require it: + if (icmp_next) + sk->sk_err = SKB_EXT_ERR(skb_next)->ee.ee_origin; But read from ee_errno.
