net: udp: introduce UDP_MIB_MEMERRORS for udp_mem
When udp_memory_allocated is at the limit, __udp_enqueue_schedule_skb will return a -ENOBUFS, and skb will be dropped in __udp_queue_rcv_skb without any counters being done. It's hard to find out what happened once this happen. So we introduce a UDP_MIB_MEMERRORS to do this job. Well, this change looks friendly to the existing users, such as netstat: $ netstat -u -s Udp: 0 packets received 639 packets to unknown port received. 158689 packet receive errors 180022 packets sent RcvbufErrors: 20930 MemErrors: 137759 UdpLite: IpExt: InOctets: 257426235 OutOctets: 257460598 InNoECTPkts: 181177 v2: - Fix some alignment problems Signed-off-by: Menglong Dong <dong.menglong@zte.com.cn> Link: https://lore.kernel.org/r/1604627354-43207-1-git-send-email-dong.menglong@zte.com.cn Signed-off-by: Jakub Kicinski <kuba@kernel.org>
