udp: sk_drops handling
In commits 33c732c36169d7022ad7d6eb474b0c9be43a2dc1 ([IPV4]: Add raw drops counter) and a92aa318b4b369091fd80433c80e62838db8bc1c ([IPV6]: Add raw drops counter), Wang Chen added raw drops counter for /proc/net/raw & /proc/net/raw6 This patch adds this capability to UDP sockets too (/proc/net/udp & /proc/net/udp6). This means that 'RcvbufErrors' errors found in /proc/net/snmp can be also be examined for each udp socket. # grep Udp: /proc/net/snmp Udp: InDatagrams NoPorts InErrors OutDatagrams RcvbufErrors SndbufErrors Udp: 23971006 75 899420 16390693 146348 0 # cat /proc/net/udp sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt --- uid timeout inode ref pointer drops 75: 00000000:02CB 00000000:0000 07 00000000:00000000 00:00000000 00000000 --- 0 0 2358 2 ffff81082a538c80 0 111: 00000000:006F 00000000:0000 07 00000000:00000000 00:00000000 00000000 --- 0 0 2286 2 ffff81042dd35c80 146348 In this example, only port 111 (0x006F) was flooded by messages that user program could not read fast enough. 146348 messages were lost.
