From 6e5d58fdc9bedd0255a8781b258f10bbdc63e975 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Wed, 14 Mar 2018 13:32:09 -0700 Subject: [PATCH] skbuff: Fix not waking applications when errors are enqueued When errors are enqueued to the error queue via sock_queue_err_skb() function, it is possible that the waiting application is not notified. Calling 'sk->sk_data_ready()' would not notify applications that selected only POLLERR events in poll() (for example). Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Reported-by: Randy E.
