+===========
+SNMP counter
+===========
+
+This document explains the meaning of SNMP counters.
+
+General IPv4 counters
+====================
+All layer 4 packets and ICMP packets will change these counters, but
+these counters won't be changed by layer 2 packets (such as STP) or
+ARP packets.
+
+* IpInReceives
+Defined in `RFC1213 ipInReceives`_
+
+.. _RFC1213 ipInReceives: https://tools.ietf.org/html/rfc1213#page-26
+
+The number of packets received by the IP layer. It gets increasing at the
+beginning of ip_rcv function, always be updated together with
+IpExtInOctets. It will be increased even if the packet is dropped
+later (e.g. due to the IP header is invalid or the checksum is wrong
+and so on).  It indicates the number of aggregated segments after
+GRO/LRO.
+
+* IpInDelivers
+Defined in `RFC1213 ipInDelivers`_
+
+.. _RFC1213 ipInDelivers: https://tools.ietf.org/html/rfc1213#page-28
+
+The number of packets delivers to the upper layer protocols. E.g. TCP, UDP,
+ICMP and so on. If no one listens on a raw socket, only kernel
+supported protocols will be delivered, if someone listens on the raw
+socket, all valid IP packets will be delivered.
+
+* IpOutRequests
+Defined in `RFC1213 ipOutRequests`_
+
+.. _RFC1213 ipOutRequests: https://tools.ietf.org/html/rfc1213#page-28
+
+The number of packets sent via IP layer, for both single cast and
+multicast packets, and would always be updated together with
+IpExtOutOctets.
+
+* IpExtInOctets and IpExtOutOctets
+They are Linux kernel extensions, no RFC definitions. Please note,
+RFC1213 indeed defines ifInOctets  and ifOutOctets, but they
+are different things. The ifInOctets and ifOutOctets include the MAC
+layer header size but IpExtInOctets and IpExtOutOctets don't, they
+only include the IP layer header and the IP layer data.
+
+* IpExtInNoECTPkts, IpExtInECT1Pkts, IpExtInECT0Pkts, IpExtInCEPkts
+They indicate the number of four kinds of ECN IP packets, please refer
+`Explicit Congestion Notification`_ for more details.
+
+.. _Explicit Congestion Notification: https://tools.ietf.org/html/rfc3168#page-6
+
+These 4 counters calculate how many packets received per ECN
+status. They count the real frame number regardless the LRO/GRO. So
+for the same packet, you might find that IpInReceives count 1, but
+IpExtInNoECTPkts counts 2 or more.
+
+* IpInHdrErrors
+Defined in `RFC1213 ipInHdrErrors`_. It indicates the packet is
+dropped due to the IP header error. It might happen in both IP input
+and IP forward paths.
+
+.. _RFC1213 ipInHdrErrors: https://tools.ietf.org/html/rfc1213#page-27
+
+* IpInAddrErrors
+Defined in `RFC1213 ipInAddrErrors`_. It will be increased in two
+scenarios: (1) The IP address is invalid. (2) The destination IP
+address is not a local address and IP forwarding is not enabled
+
+.. _RFC1213 ipInAddrErrors: https://tools.ietf.org/html/rfc1213#page-27
+
+* IpExtInNoRoutes
+This counter means the packet is dropped when the IP stack receives a
+packet and can't find a route for it from the route table. It might
+happen when IP forwarding is enabled and the destination IP address is
+not a local address and there is no route for the destination IP
+address.
+
+* IpInUnknownProtos
+Defined in `RFC1213 ipInUnknownProtos`_. It will be increased if the
+layer 4 protocol is unsupported by kernel. If an application is using
+raw socket, kernel will always deliver the packet to the raw socket
+and this counter won't be increased.
+
+.. _RFC1213 ipInUnknownProtos: https://tools.ietf.org/html/rfc1213#page-27
+
+* IpExtInTruncatedPkts
+For IPv4 packet, it means the actual data size is smaller than the
+"Total Length" field in the IPv4 header.
+
+* IpInDiscards
+Defined in `RFC1213 ipInDiscards`_. It indicates the packet is dropped
+in the IP receiving path and due to kernel internal reasons (e.g. no
+enough memory).
+
+.. _RFC1213 ipInDiscards: https://tools.ietf.org/html/rfc1213#page-28
+
+* IpOutDiscards
+Defined in `RFC1213 ipOutDiscards`_. It indicates the packet is
+dropped in the IP sending path and due to kernel internal reasons.
+
+.. _RFC1213 ipOutDiscards: https://tools.ietf.org/html/rfc1213#page-28
+
+* IpOutNoRoutes
+Defined in `RFC1213 ipOutNoRoutes`_. It indicates the packet is
+dropped in the IP sending path and no route is found for it.
+
+.. _RFC1213 ipOutNoRoutes: https://tools.ietf.org/html/rfc1213#page-29
+
+ICMP counters
+============
+* IcmpInMsgs and IcmpOutMsgs
+Defined by `RFC1213 icmpInMsgs`_ and `RFC1213 icmpOutMsgs`_
+
+.. _RFC1213 icmpInMsgs: https://tools.ietf.org/html/rfc1213#page-41
+.. _RFC1213 icmpOutMsgs: https://tools.ietf.org/html/rfc1213#page-43
+
+As mentioned in the RFC1213, these two counters include errors, they
+would be increased even if the ICMP packet has an invalid type. The
+ICMP output path will check the header of a raw socket, so the
+IcmpOutMsgs would still be updated if the IP header is constructed by
+a userspace program.
+
+* ICMP named types
+| These counters include most of common ICMP types, they are:

+.. _RFC1213 icmpOutAddrMaskReps: https://tools.ietf.org/html/rfc1213#page-46
+
+Every ICMP type has two counters: 'In' and 'Out'. E.g., for the ICMP
+Echo packet, they are IcmpInEchos and IcmpOutEchos. Their meanings are
+straightforward. The 'In' counter means kernel receives such a packet
+and the 'Out' counter means kernel sends such a packet.
+
+* ICMP numeric types
+They are IcmpMsgInType[N] and IcmpMsgOutType[N], the [N] indicates the
+ICMP type number. These counters track all kinds of ICMP packets. The
+ICMP type number definition could be found in the `ICMP parameters`_
+document.
+
+.. _ICMP parameters: https://www.iana.org/assignments/icmp-parameters/icmp-parameters.xhtml
+
+For example, if the Linux kernel sends an ICMP Echo packet, the
+IcmpMsgOutType8 would increase 1. And if kernel gets an ICMP Echo Reply
+packet, IcmpMsgInType0 would increase 1.
+
+* IcmpInCsumErrors
+This counter indicates the checksum of the ICMP packet is
+wrong. Kernel verifies the checksum after updating the IcmpInMsgs and
+before updating IcmpMsgInType[N]. If a packet has bad checksum, the
+IcmpInMsgs would be updated but none of IcmpMsgInType[N] would be updated.
+
+* IcmpInErrors and IcmpOutErrors
+Defined by `RFC1213 icmpInErrors`_ and `RFC1213 icmpOutErrors`_
+
+.. _RFC1213 icmpInErrors: https://tools.ietf.org/html/rfc1213#page-41
+.. _RFC1213 icmpOutErrors: https://tools.ietf.org/html/rfc1213#page-43
+
+When an error occurs in the ICMP packet handler path, these two
+counters would be updated. The receiving packet path use IcmpInErrors
+and the sending packet path use IcmpOutErrors. When IcmpInCsumErrors
+is increased, IcmpInErrors would always be increased too.
+
+relationship of the ICMP counters
+-------------------------------
+The sum of IcmpMsgOutType[N] is always equal to IcmpOutMsgs, as they
+are updated at the same time. The sum of IcmpMsgInType[N] plus
+IcmpInErrors should be equal or larger than IcmpInMsgs. When kernel
+receives an ICMP packet, kernel follows below logic:
+
+1. increase IcmpInMsgs
+2. if has any error, update IcmpInErrors and finish the process
+3. update IcmpMsgOutType[N]
+4. handle the packet depending on the type, if has any error, update
+   IcmpInErrors and finish the process
+
+So if all errors occur in step (2), IcmpInMsgs should be equal to the
+sum of IcmpMsgOutType[N] plus IcmpInErrors. If all errors occur in
+step (4), IcmpInMsgs should be equal to the sum of
+IcmpMsgOutType[N]. If the errors occur in both step (2) and step (4),
+IcmpInMsgs should be less than the sum of IcmpMsgOutType[N] plus
+IcmpInErrors.
+
+General TCP counters
+==================
+* TcpInSegs
+Defined in `RFC1213 tcpInSegs`_
+
+.. _RFC1213 tcpInSegs: https://tools.ietf.org/html/rfc1213#page-48
+
+The number of packets received by the TCP layer. As mentioned in
+RFC1213, it includes the packets received in error, such as checksum
+error, invalid TCP header and so on. Only one error won't be included:
+if the layer 2 destination address is not the NIC's layer 2
+address. It might happen if the packet is a multicast or broadcast
+packet, or the NIC is in promiscuous mode. In these situations, the
+packets would be delivered to the TCP layer, but the TCP layer will discard
+these packets before increasing TcpInSegs. The TcpInSegs counter
+isn't aware of GRO. So if two packets are merged by GRO, the TcpInSegs
+counter would only increase 1.
+
+* TcpOutSegs
+Defined in `RFC1213 tcpOutSegs`_
+
+.. _RFC1213 tcpOutSegs: https://tools.ietf.org/html/rfc1213#page-48
+
+The number of packets sent by the TCP layer. As mentioned in RFC1213,
+it excludes the retransmitted packets. But it includes the SYN, ACK
+and RST packets. Doesn't like TcpInSegs, the TcpOutSegs is aware of
+GSO, so if a packet would be split to 2 by GSO, TcpOutSegs will
+increase 2.
+
+* TcpActiveOpens
+Defined in `RFC1213 tcpActiveOpens`_
+
+.. _RFC1213 tcpActiveOpens: https://tools.ietf.org/html/rfc1213#page-47
+
+It means the TCP layer sends a SYN, and come into the SYN-SENT
+state. Every time TcpActiveOpens increases 1, TcpOutSegs should always
+increase 1.
+
+* TcpPassiveOpens
+Defined in `RFC1213 tcpPassiveOpens`_
+
+.. _RFC1213 tcpPassiveOpens: https://tools.ietf.org/html/rfc1213#page-47
+
+It means the TCP layer receives a SYN, replies a SYN+ACK, come into
+the SYN-RCVD state.
+
+* TcpExtTCPRcvCoalesce
+When packets are received by the TCP layer and are not be read by the
+application, the TCP layer will try to merge them. This counter
+indicate how many packets are merged in such situation. If GRO is
+enabled, lots of packets would be merged by GRO, these packets
+wouldn't be counted to TcpExtTCPRcvCoalesce.
+
+* TcpExtTCPAutoCorking
+When sending packets, the TCP layer will try to merge small packets to
+a bigger one. This counter increase 1 for every packet merged in such
+situation. Please refer to the LWN article for more details:
+https://lwn.net/Articles/576263/
+
+* TcpExtTCPOrigDataSent
+This counter is explained by `kernel commit f19c29e3e391`_, I pasted the
+explaination below::
+
+  TCPOrigDataSent: number of outgoing packets with original data (excluding
+  retransmission but including data-in-SYN). This counter is different from
+  TcpOutSegs because TcpOutSegs also tracks pure ACKs. TCPOrigDataSent is
+  more useful to track the TCP retransmission rate.
+
+* TCPSynRetrans
+This counter is explained by `kernel commit f19c29e3e391`_, I pasted the
+explaination below::
+
+  TCPSynRetrans: number of SYN and SYN/ACK retransmits to break down
+  retransmissions into SYN, fast-retransmits, timeout retransmits, etc.
+
+* TCPFastOpenActiveFail
+This counter is explained by `kernel commit f19c29e3e391`_, I pasted the
+explaination below::
+
+  TCPFastOpenActiveFail: Fast Open attempts (SYN/data) failed because
+  the remote does not accept it or the attempts timed out.
+
+.. _kernel commit f19c29e3e391: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f19c29e3e391a66a273e9afebaf01917245148cd
+
+* TcpExtListenOverflows and TcpExtListenDrops
+When kernel receives a SYN from a client, and if the TCP accept queue
+is full, kernel will drop the SYN and add 1 to TcpExtListenOverflows.
+At the same time kernel will also add 1 to TcpExtListenDrops. When a
+TCP socket is in LISTEN state, and kernel need to drop a packet,
+kernel would always add 1 to TcpExtListenDrops. So increase
+TcpExtListenOverflows would let TcpExtListenDrops increasing at the
+same time, but TcpExtListenDrops would also increase without
+TcpExtListenOverflows increasing, e.g. a memory allocation fail would
+also let TcpExtListenDrops increase.
+
+Note: The above explanation is based on kernel 4.10 or above version, on
+an old kernel, the TCP stack has different behavior when TCP accept
+queue is full. On the old kernel, TCP stack won't drop the SYN, it
+would complete the 3-way handshake. As the accept queue is full, TCP
+stack will keep the socket in the TCP half-open queue. As it is in the
+half open queue, TCP stack will send SYN+ACK on an exponential backoff
+timer, after client replies ACK, TCP stack checks whether the accept
+queue is still full, if it is not full, moves the socket to the accept
+queue, if it is full, keeps the socket in the half-open queue, at next
+time client replies ACK, this socket will get another chance to move
+to the accept queue.
+
+
+TCP Fast Open
+============
+When kernel receives a TCP packet, it has two paths to handler the
+packet, one is fast path, another is slow path. The comment in kernel
+code provides a good explanation of them, I pasted them below::
+
+  It is split into a fast path and a slow path. The fast path is
+  disabled when:
+
+  - A zero window was announced from us
+  - zero window probing
+    is only handled properly on the slow path.
+  - Out of order segments arrived.
+  - Urgent data is expected.
+  - There is no buffer space left
+  - Unexpected TCP flags/window values/header lengths are received
+    (detected by checking the TCP header against pred_flags)
+  - Data is sent in both directions. The fast path only supports pure senders
+    or pure receivers (this means either the sequence number or the ack
+    value must stay constant)
+  - Unexpected TCP option.
+
+Kernel will try to use fast path unless any of the above conditions
+are satisfied. If the packets are out of order, kernel will handle
+them in slow path, which means the performance might be not very
+good. Kernel would also come into slow path if the "Delayed ack" is
+used, because when using "Delayed ack", the data is sent in both
+directions. When the TCP window scale option is not used, kernel will
+try to enable fast path immediately when the connection comes into the
+established state, but if the TCP window scale option is used, kernel
+will disable the fast path at first, and try to enable it after kernel
+receives packets.
+
+* TcpExtTCPPureAcks and TcpExtTCPHPAcks
+If a packet set ACK flag and has no data, it is a pure ACK packet, if
+kernel handles it in the fast path, TcpExtTCPHPAcks will increase 1,
+if kernel handles it in the slow path, TcpExtTCPPureAcks will
+increase 1.
+
+* TcpExtTCPHPHits
+If a TCP packet has data (which means it is not a pure ACK packet),
+and this packet is handled in the fast path, TcpExtTCPHPHits will
+increase 1.
+
+
+TCP abort
+========
+
+
+* TcpExtTCPAbortOnData
+It means TCP layer has data in flight, but need to close the
+connection. So TCP layer sends a RST to the other side, indicate the
+connection is not closed very graceful. An easy way to increase this
+counter is using the SO_LINGER option. Please refer to the SO_LINGER
+section of the `socket man page`_:
+
+.. _socket man page: http://man7.org/linux/man-pages/man7/socket.7.html
+
+By default, when an application closes a connection, the close function
+will return immediately and kernel will try to send the in-flight data
+async. If you use the SO_LINGER option, set l_onoff to 1, and l_linger
+to a positive number, the close function won't return immediately, but
+wait for the in-flight data are acked by the other side, the max wait
+time is l_linger seconds. If set l_onoff to 1 and set l_linger to 0,
+when the application closes a connection, kernel will send a RST
+immediately and increase the TcpExtTCPAbortOnData counter.
+
+* TcpExtTCPAbortOnClose
+This counter means the application has unread data in the TCP layer when
+the application wants to close the TCP connection. In such a situation,
+kernel will send a RST to the other side of the TCP connection.
+
+* TcpExtTCPAbortOnMemory
+When an application closes a TCP connection, kernel still need to track
+the connection, let it complete the TCP disconnect process. E.g. an
+app calls the close method of a socket, kernel sends fin to the other
+side of the connection, then the app has no relationship with the
+socket any more, but kernel need to keep the socket, this socket
+becomes an orphan socket, kernel waits for the reply of the other side,
+and would come to the TIME_WAIT state finally. When kernel has no
+enough memory to keep the orphan socket, kernel would send an RST to
+the other side, and delete the socket, in such situation, kernel will
+increase 1 to the TcpExtTCPAbortOnMemory. Two conditions would trigger
+TcpExtTCPAbortOnMemory:
+
+1. the memory used by the TCP protocol is higher than the third value of
+the tcp_mem. Please refer the tcp_mem section in the `TCP man page`_:
+
+.. _TCP man page: http://man7.org/linux/man-pages/man7/tcp.7.html
+
+2. the orphan socket count is higher than net.ipv4.tcp_max_orphans
+
+
+* TcpExtTCPAbortOnTimeout
+This counter will increase when any of the TCP timers expire. In such
+situation, kernel won't send RST, just give up the connection.
+
+* TcpExtTCPAbortOnLinger
+When a TCP connection comes into FIN_WAIT_2 state, instead of waiting
+for the fin packet from the other side, kernel could send a RST and
+delete the socket immediately. This is not the default behavior of
+Linux kernel TCP stack. By configuring the TCP_LINGER2 socket option,
+you could let kernel follow this behavior.
+
+* TcpExtTCPAbortFailed
+The kernel TCP layer will send RST if the `RFC2525 2.17 section`_ is
+satisfied. If an internal error occurs during this process,
+TcpExtTCPAbortFailed will be increased.
+
+.. _RFC2525 2.17 section: https://tools.ietf.org/html/rfc2525#page-50
+
+TCP Hybrid Slow Start
+====================
+The Hybrid Slow Start algorithm is an enhancement of the traditional
+TCP congestion window Slow Start algorithm. It uses two pieces of
+information to detect whether the max bandwidth of the TCP path is
+approached. The two pieces of information are ACK train length and
+increase in packet delay. For detail information, please refer the
+`Hybrid Slow Start paper`_. Either ACK train length or packet delay
+hits a specific threshold, the congestion control algorithm will come
+into the Congestion Avoidance state. Until v4.20, two congestion
+control algorithms are using Hybrid Slow Start, they are cubic (the
+default congestion control algorithm) and cdg. Four snmp counters
+relate with the Hybrid Slow Start algorithm.
+
+.. _Hybrid Slow Start paper: https://pdfs.semanticscholar.org/25e9/ef3f03315782c7f1cbcd31b587857adae7d1.pdf
+
+* TcpExtTCPHystartTrainDetect
+How many times the ACK train length threshold is detected
+
+* TcpExtTCPHystartTrainCwnd
+The sum of CWND detected by ACK train length. Dividing this value by
+TcpExtTCPHystartTrainDetect is the average CWND which detected by the
+ACK train length.
+
+* TcpExtTCPHystartDelayDetect
+How many times the packet delay threshold is detected.
+
+* TcpExtTCPHystartDelayCwnd
+The sum of CWND detected by packet delay. Dividing this value by
+TcpExtTCPHystartDelayDetect is the average CWND which detected by the
+packet delay.
+
+TCP retransmission and congestion control
+======================================
+The TCP protocol has two retransmission mechanisms: SACK and fast
+recovery. They are exclusive with each other. When SACK is enabled,
+the kernel TCP stack would use SACK, or kernel would use fast
+recovery. The SACK is a TCP option, which is defined in `RFC2018`_,
+the fast recovery is defined in `RFC6582`_, which is also called
+'Reno'.
+
+The TCP congestion control is a big and complex topic. To understand
+the related snmp counter, we need to know the states of the congestion
+control state machine. There are 5 states: Open, Disorder, CWR,
+Recovery and Loss. For details about these states, please refer page 5
+and page 6 of this document:
+https://pdfs.semanticscholar.org/0e9c/968d09ab2e53e24c4dca5b2d67c7f7140f8e.pdf
+
+.. _RFC2018: https://tools.ietf.org/html/rfc2018
+.. _RFC6582: https://tools.ietf.org/html/rfc6582
+
+* TcpExtTCPRenoRecovery and TcpExtTCPSackRecovery
+When the congestion control comes into Recovery state, if sack is
+used, TcpExtTCPSackRecovery increases 1, if sack is not used,
+TcpExtTCPRenoRecovery increases 1. These two counters mean the TCP
+stack begins to retransmit the lost packets.
+
+* TcpExtTCPSACKReneging
+A packet was acknowledged by SACK, but the receiver has dropped this
+packet, so the sender needs to retransmit this packet. In this
+situation, the sender adds 1 to TcpExtTCPSACKReneging. A receiver
+could drop a packet which has been acknowledged by SACK, although it is
+unusual, it is allowed by the TCP protocol. The sender doesn't really
+know what happened on the receiver side. The sender just waits until
+the RTO expires for this packet, then the sender assumes this packet
+has been dropped by the receiver.
+
+* TcpExtTCPRenoReorder
+The reorder packet is detected by fast recovery. It would only be used
+if SACK is disabled. The fast recovery algorithm detects recorder by
+the duplicate ACK number. E.g., if retransmission is triggered, and
+the original retransmitted packet is not lost, it is just out of
+order, the receiver would acknowledge multiple times, one for the
+retransmitted packet, another for the arriving of the original out of
+order packet. Thus the sender would find more ACks than its
+expectation, and the sender knows out of order occurs.
+
+* TcpExtTCPTSReorder
+The reorder packet is detected when a hole is filled. E.g., assume the
+sender sends packet 1,2,3,4,5, and the receiving order is
+1,2,4,5,3. When the sender receives the ACK of packet 3 (which will
+fill the hole), two conditions will let TcpExtTCPTSReorder increase
+1: (1) if the packet 3 is not re-retransmitted yet. (2) if the packet
+3 is retransmitted but the timestamp of the packet 3's ACK is earlier
+than the retransmission timestamp.
+
+* TcpExtTCPSACKReorder
+The reorder packet detected by SACK. The SACK has two methods to
+detect reorder: (1) DSACK is received by the sender. It means the
+sender sends the same packet more than one times. And the only reason
+is the sender believes an out of order packet is lost so it sends the
+packet again. (2) Assume packet 1,2,3,4,5 are sent by the sender, and
+the sender has received SACKs for packet 2 and 5, now the sender
+receives SACK for packet 4 and the sender doesn't retransmit the
+packet yet, the sender would know packet 4 is out of order. The TCP
+stack of kernel will increase TcpExtTCPSACKReorder for both of the
+above scenarios.
+
+
+DSACK
+=====
+The DSACK is defined in `RFC2883`_. The receiver uses DSACK to report
+duplicate packets to the sender. There are two kinds of
+duplications: (1) a packet which has been acknowledged is
+duplicate. (2) an out of order packet is duplicate. The TCP stack
+counts these two kinds of duplications on both receiver side and
+sender side.
+
+.. _RFC2883 : https://tools.ietf.org/html/rfc2883
+
+* TcpExtTCPDSACKOldSent
+The TCP stack receives a duplicate packet which has been acked, so it
+sends a DSACK to the sender.
+
+* TcpExtTCPDSACKOfoSent
+The TCP stack receives an out of order duplicate packet, so it sends a
+DSACK to the sender.
+
+* TcpExtTCPDSACKRecv
+The TCP stack receives a DSACK, which indicate an acknowledged
+duplicate packet is received.
+
+* TcpExtTCPDSACKOfoRecv
+The TCP stack receives a DSACK, which indicate an out of order
+duplciate packet is received.

+  IpExtInNoECTPkts                1                  0.0
+
+The Linux server sent an ICMP Echo packet, so IpOutRequests,
+IcmpOutMsgs, IcmpOutEchos and IcmpMsgOutType8 were increased 1. The
+server got ICMP Echo Reply from 8.8.8.8, so IpInReceives, IcmpInMsgs,
+IcmpInEchoReps and IcmpMsgInType0 were increased 1. The ICMP Echo Reply
+was passed to the ICMP layer via IP layer, so IpInDelivers was
+increased 1. The default ping data size is 48, so an ICMP Echo packet
+and its corresponding Echo Reply packet are constructed by:
+
+* 14 bytes MAC header
+* 20 bytes IP header
+* 16 bytes ICMP header
+* 48 bytes data (default value of the ping command)
+
+So the IpExtInOctets and IpExtOutOctets are 20+16+48=84.

+tcp 3-way handshake
+------------------
+On server side, we run::
+
+  nstatuser@nstat-b:~$ nc -lknv 0.0.0.0 9000
+  Listening on [0.0.0.0] (family 0, port 9000)
+
+On client side, we run::
+
+  nstatuser@nstat-a:~$ nc -nv 192.168.122.251 9000
+  Connection to 192.168.122.251 9000 port [tcp/*] succeeded!
+
+The server listened on tcp 9000 port, the client connected to it, they
+completed the 3-way handshake.
+
+On server side, we can find below nstat output::

+
+When the server received the first SYN, it replied a SYN+ACK, and came into
+SYN-RCVD state, so TcpPassiveOpens increased 1. The server received
+SYN, sent SYN+ACK, received ACK, so server sent 1 packet, received 2
+packets, TcpInSegs increased 2, TcpOutSegs increased 1. The last ACK
+of the 3-way handshake is a pure ACK without data, so
+TcpExtTCPPureAcks increased 1.
+
+When the client sent SYN, the client came into the SYN-SENT state, so
+TcpActiveOpens increased 1, the client sent SYN, received SYN+ACK, sent
+ACK, so client sent 2 packets, received 1 packet, TcpInSegs increased
+1, TcpOutSegs increased 2.

+
+Compare the first client-side nstat and the second client-side nstat,
+we could find one difference: the first one had a 'TcpExtTCPPureAcks',
+but the second one had a 'TcpExtTCPHPAcks'. The first server-side
+nstat and the second server-side nstat had a difference too: the
+second server-side nstat had a TcpExtTCPHPHits, but the first
+server-side nstat didn't have it. The network traffic patterns were
+exactly the same: the client sent a packet to the server, the server
+replied an ACK. But kernel handled them in different ways. When the
+TCP window scale option is not used, kernel will try to enable fast
+path immediately when the connection comes into the established state,
+but if the TCP window scale option is used, kernel will disable the
+fast path at first, and try to enable it after kerenl receives
+packets. We could use the 'ss' command to verify whether the window
+scale option is used. e.g. run below command on either server or
+client::
+
+  nstatuser@nstat-a:~$ ss -o state established -i '( dport = :9000 or sport = :9000 )
+  Netid    Recv-Q     Send-Q            Local Address:Port             Peer Address:Port
+  tcp      0          0               192.168.122.250:40654         192.168.122.251:9000

+
+The 'wscale:7,7' means both server and client set the window scale
+option to 7. Now we could explain the nstat output in our test:
+
+In the first nstat output of client side, the client sent a packet, server
+reply an ACK, when kernel handled this ACK, the fast path was not
+enabled, so the ACK was counted into 'TcpExtTCPPureAcks'.
+
+In the second nstat output of client side, the client sent a packet again,
+and received another ACK from the server, in this time, the fast path is
+enabled, and the ACK was qualified for fast path, so it was handled by
+the fast path, so this ACK was counted into TcpExtTCPHPAcks.
+
+In the first nstat output of server side, fast path was not enabled,
+so there was no 'TcpExtTCPHPHits'.
+
+In the second nstat output of server side, the fast path was enabled,
+and the packet received from client qualified for fast path, so it
+was counted into 'TcpExtTCPHPHits'.
+
+TcpExtTCPAbortOnClose
+--------------------
+On the server side, we run below python script::
+
+  import socket
+  import time
+
+  port = 9000
+
+  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+  s.bind(('0.0.0.0', port))
+  s.listen(1)
+  sock, addr = s.accept()
+  while True:
+      time.sleep(9999999)
+
+This python script listen on 9000 port, but doesn't read anything from
+the connection.
+
+On the client side, we send the string "hello" by nc::
+
+  nstatuser@nstat-a:~$ echo "hello" | nc nstat-b 9000
+
+Then, we come back to the server side, the server has received the "hello"
+packet, and the TCP layer has acked this packet, but the application didn't
+read it yet. We type Ctrl-C to terminate the server script. Then we
+could find TcpExtTCPAbortOnClose increased 1 on the server side::
+
+  nstatuser@nstat-b:~$ nstat | grep -i abort
+  TcpExtTCPAbortOnClose           1                  0.0
+
+If we run tcpdump on the server side, we could find the server sent a
+RST after we type Ctrl-C.
+
+TcpExtTCPAbortOnMemory and TcpExtTCPAbortOnTimeout
+-----------------------------------------------
+Below is an example which let the orphan socket count be higher than
+net.ipv4.tcp_max_orphans.
+Change tcp_max_orphans to a smaller value on client::
+
+  sudo bash -c "echo 10 > /proc/sys/net/ipv4/tcp_max_orphans"
+
+Client code (create 64 connection to server)::
+
+  nstatuser@nstat-a:~$ cat client_orphan.py
+  import socket
+  import time
+
+  server = 'nstat-b' # server address
+  port = 9000
+
+  count = 64
+
+  connection_list = []
+
+  for i in range(64):
+      s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+      s.connect((server, port))
+      connection_list.append(s)
+      print("connection_count: %d" % len(connection_list))
+
+  while True:
+      time.sleep(99999)
+
+Server code (accept 64 connection from client)::
+
+  nstatuser@nstat-b:~$ cat server_orphan.py
+  import socket
+  import time
+
+  port = 9000
+  count = 64
+
+  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+  s.bind(('0.0.0.0', port))
+  s.listen(count)
+  connection_list = []
+  while True:
+      sock, addr = s.accept()
+      connection_list.append((sock, addr))
+      print("connection_count: %d" % len(connection_list))
+
+Run the python scripts on server and client.
+
+On server::
+
+  python3 server_orphan.py
+
+On client::
+
+  python3 client_orphan.py
+
+Run iptables on server::
+
+  sudo iptables -A INPUT -i ens3 -p tcp --destination-port 9000 -j DROP
+
+Type Ctrl-C on client, stop client_orphan.py.
+
+Check TcpExtTCPAbortOnMemory on client::
+
+  nstatuser@nstat-a:~$ nstat | grep -i abort
+  TcpExtTCPAbortOnMemory          54                 0.0
+
+Check orphane socket count on client::
+
+  nstatuser@nstat-a:~$ ss -s
+  Total: 131 (kernel 0)
+  TCP:   14 (estab 1, closed 0, orphaned 10, synrecv 0, timewait 0/0), ports 0
+
+  Transport Total     IP        IPv6
+  *         0         -         -
+  RAW       1         0         1
+  UDP       1         1         0
+  TCP       14        13        1
+  INET      16        14        2
+  FRAG      0         0         0
+
+The explanation of the test: after run server_orphan.py and
+client_orphan.py, we set up 64 connections between server and
+client. Run the iptables command, the server will drop all packets from
+the client, type Ctrl-C on client_orphan.py, the system of the client
+would try to close these connections, and before they are closed
+gracefully, these connections became orphan sockets. As the iptables
+of the server blocked packets from the client, the server won't receive fin
+from the client, so all connection on clients would be stuck on FIN_WAIT_1
+stage, so they will keep as orphan sockets until timeout. We have echo
+10 to /proc/sys/net/ipv4/tcp_max_orphans, so the client system would
+only keep 10 orphan sockets, for all other orphan sockets, the client
+system sent RST for them and delete them. We have 64 connections, so
+the 'ss -s' command shows the system has 10 orphan sockets, and the
+value of TcpExtTCPAbortOnMemory was 54.
+
+An additional explanation about orphan socket count: You could find the
+exactly orphan socket count by the 'ss -s' command, but when kernel
+decide whither increases TcpExtTCPAbortOnMemory and sends RST, kernel
+doesn't always check the exactly orphan socket count. For increasing
+performance, kernel checks an approximate count firstly, if the
+approximate count is more than tcp_max_orphans, kernel checks the
+exact count again. So if the approximate count is less than
+tcp_max_orphans, but exactly count is more than tcp_max_orphans, you
+would find TcpExtTCPAbortOnMemory is not increased at all. If
+tcp_max_orphans is large enough, it won't occur, but if you decrease
+tcp_max_orphans to a small value like our test, you might find this
+issue. So in our test, the client set up 64 connections although the
+tcp_max_orphans is 10. If the client only set up 11 connections, we
+can't find the change of TcpExtTCPAbortOnMemory.
+
+Continue the previous test, we wait for several minutes. Because of the
+iptables on the server blocked the traffic, the server wouldn't receive
+fin, and all the client's orphan sockets would timeout on the
+FIN_WAIT_1 state finally. So we wait for a few minutes, we could find
+10 timeout on the client::
+
+  nstatuser@nstat-a:~$ nstat | grep -i abort
+  TcpExtTCPAbortOnTimeout         10                 0.0
+
+TcpExtTCPAbortOnLinger
+---------------------
+The server side code::
+
+  nstatuser@nstat-b:~$ cat server_linger.py
+  import socket
+  import time
+
+  port = 9000
+
+  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+  s.bind(('0.0.0.0', port))
+  s.listen(1)
+  sock, addr = s.accept()
+  while True:
+      time.sleep(9999999)
+
+The client side code::
+
+  nstatuser@nstat-a:~$ cat client_linger.py
+  import socket
+  import struct
+
+  server = 'nstat-b' # server address
+  port = 9000
+
+  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+  s.setsockopt(socket.SOL_SOCKET, socket.SO_LINGER, struct.pack('ii', 1, 10))
+  s.setsockopt(socket.SOL_TCP, socket.TCP_LINGER2, struct.pack('i', -1))
+  s.connect((server, port))
+  s.close()
+
+Run server_linger.py on server::
+
+  nstatuser@nstat-b:~$ python3 server_linger.py
+
+Run client_linger.py on client::
+
+  nstatuser@nstat-a:~$ python3 client_linger.py
+
+After run client_linger.py, check the output of nstat::
+
+  nstatuser@nstat-a:~$ nstat | grep -i abort
+  TcpExtTCPAbortOnLinger          1                  0.0
+
+TcpExtTCPRcvCoalesce
+-------------------
+On the server, we run a program which listen on TCP port 9000, but
+doesn't read any data::
+
+  import socket
+  import time
+  port = 9000
+  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+  s.bind(('0.0.0.0', port))
+  s.listen(1)
+  sock, addr = s.accept()
+  while True:
+      time.sleep(9999999)
+
+Save the above code as server_coalesce.py, and run::
+
+  python3 server_coalesce.py
+
+On the client, save below code as client_coalesce.py::
+
+  import socket
+  server = 'nstat-b'
+  port = 9000
+  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+  s.connect((server, port))
+
+Run::
+
+  nstatuser@nstat-a:~$ python3 -i client_coalesce.py
+
+We use '-i' to come into the interactive mode, then a packet::
+
+  >>> s.send(b'foo')
+  3
+
+Send a packet again::
+
+  >>> s.send(b'bar')
+  3
+
+On the server, run nstat::
+
+  ubuntu@nstat-b:~$ nstat
+  #kernel
+  IpInReceives                    2                  0.0
+  IpInDelivers                    2                  0.0
+  IpOutRequests                   2                  0.0
+  TcpInSegs                       2                  0.0
+  TcpOutSegs                      2                  0.0
+  TcpExtTCPRcvCoalesce            1                  0.0
+  IpExtInOctets                   110                0.0
+  IpExtOutOctets                  104                0.0
+  IpExtInNoECTPkts                2                  0.0
+
+The client sent two packets, server didn't read any data. When
+the second packet arrived at server, the first packet was still in
+the receiving queue. So the TCP layer merged the two packets, and we
+could find the TcpExtTCPRcvCoalesce increased 1.
+
+TcpExtListenOverflows and TcpExtListenDrops
+----------------------------------------
+On server, run the nc command, listen on port 9000::
+
+  nstatuser@nstat-b:~$ nc -lkv 0.0.0.0 9000
+  Listening on [0.0.0.0] (family 0, port 9000)
+
+On client, run 3 nc commands in different terminals::
+
+  nstatuser@nstat-a:~$ nc -v nstat-b 9000
+  Connection to nstat-b 9000 port [tcp/*] succeeded!
+
+The nc command only accepts 1 connection, and the accept queue length
+is 1. On current linux implementation, set queue length to n means the
+actual queue length is n+1. Now we create 3 connections, 1 is accepted
+by nc, 2 in accepted queue, so the accept queue is full.
+
+Before running the 4th nc, we clean the nstat history on the server::
+
+  nstatuser@nstat-b:~$ nstat -n
+
+Run the 4th nc on the client::
+
+  nstatuser@nstat-a:~$ nc -v nstat-b 9000
+
+If the nc server is running on kernel 4.10 or higher version, you
+won't see the "Connection to ... succeeded!" string, because kernel
+will drop the SYN if the accept queue is full. If the nc client is running
+on an old kernel, you would see that the connection is succeeded,
+because kernel would complete the 3 way handshake and keep the socket
+on half open queue. I did the test on kernel 4.15. Below is the nstat
+on the server::
+
+  nstatuser@nstat-b:~$ nstat
+  #kernel
+  IpInReceives                    4                  0.0
+  IpInDelivers                    4                  0.0
+  TcpInSegs                       4                  0.0
+  TcpExtListenOverflows           4                  0.0
+  TcpExtListenDrops               4                  0.0
+  IpExtInOctets                   240                0.0
+  IpExtInNoECTPkts                4                  0.0
+
+Both TcpExtListenOverflows and TcpExtListenDrops were 4. If the time
+between the 4th nc and the nstat was longer, the value of
+TcpExtListenOverflows and TcpExtListenDrops would be larger, because
+the SYN of the 4th nc was dropped, the client was retrying.
+
+IpInAddrErrors, IpExtInNoRoutes and IpOutNoRoutes
+----------------------------------------------
+server A IP address: 192.168.122.250
+server B IP address: 192.168.122.251
+Prepare on server A, add a route to server B::
+
+  $ sudo ip route add 8.8.8.8/32 via 192.168.122.251
+
+Prepare on server B, disable send_redirects for all interfaces::
+
+  $ sudo sysctl -w net.ipv4.conf.all.send_redirects=0
+  $ sudo sysctl -w net.ipv4.conf.ens3.send_redirects=0
+  $ sudo sysctl -w net.ipv4.conf.lo.send_redirects=0
+  $ sudo sysctl -w net.ipv4.conf.default.send_redirects=0
+
+We want to let sever A send a packet to 8.8.8.8, and route the packet
+to server B. When server B receives such packet, it might send a ICMP
+Redirect message to server A, set send_redirects to 0 will disable
+this behavior.
+
+First, generate InAddrErrors. On server B, we disable IP forwarding::
+
+  $ sudo sysctl -w net.ipv4.conf.all.forwarding=0
+
+On server A, we send packets to 8.8.8.8::
+
+  $ nc -v 8.8.8.8 53
+
+On server B, we check the output of nstat::
+
+  $ nstat
+  #kernel
+  IpInReceives                    3                  0.0
+  IpInAddrErrors                  3                  0.0
+  IpExtInOctets                   180                0.0
+  IpExtInNoECTPkts                3                  0.0
+
+As we have let server A route 8.8.8.8 to server B, and we disabled IP
+forwarding on server B, Server A sent packets to server B, then server B
+dropped packets and increased IpInAddrErrors. As the nc command would
+re-send the SYN packet if it didn't receive a SYN+ACK, we could find
+multiple IpInAddrErrors.
+
+Second, generate IpExtInNoRoutes. On server B, we enable IP
+forwarding::
+
+  $ sudo sysctl -w net.ipv4.conf.all.forwarding=1
+
+Check the route table of server B and remove the default route::
+
+  $ ip route show
+  default via 192.168.122.1 dev ens3 proto static
+  192.168.122.0/24 dev ens3 proto kernel scope link src 192.168.122.251
+  $ sudo ip route delete default via 192.168.122.1 dev ens3 proto static
+
+On server A, we contact 8.8.8.8 again::
+
+  $ nc -v 8.8.8.8 53
+  nc: connect to 8.8.8.8 port 53 (tcp) failed: Network is unreachable
+
+On server B, run nstat::
+
+  $ nstat
+  #kernel
+  IpInReceives                    1                  0.0
+  IpOutRequests                   1                  0.0
+  IcmpOutMsgs                     1                  0.0
+  IcmpOutDestUnreachs             1                  0.0
+  IcmpMsgOutType3                 1                  0.0
+  IpExtInNoRoutes                 1                  0.0
+  IpExtInOctets                   60                 0.0
+  IpExtOutOctets                  88                 0.0
+  IpExtInNoECTPkts                1                  0.0
+
+We enabled IP forwarding on server B, when server B received a packet
+which destination IP address is 8.8.8.8, server B will try to forward
+this packet. We have deleted the default route, there was no route for
+8.8.8.8, so server B increase IpExtInNoRoutes and sent the "ICMP
+Destination Unreachable" message to server A.
+
+Third, generate IpOutNoRoutes. Run ping command on server B::
+
+  $ ping -c 1 8.8.8.8
+  connect: Network is unreachable
+
+Run nstat on server B::
+
+  $ nstat
+  #kernel
+  IpOutNoRoutes                   1                  0.0
+
+We have deleted the default route on server B. Server B couldn't find
+a route for the 8.8.8.8 IP address, so server B increased
+IpOutNoRoutes.

+	 * more precisely an entity representing a group, as still
+	 * counted in num_groups_with_pending_reqs when it becomes
+	 * inactive. Then, when the first descendant queue of the

+libbpf API naming convention
+============================
+
+libbpf API provides access to a few logically separated groups of
+functions and types. Every group has its own naming convention
+described here. It's recommended to follow these conventions whenever a
+new function or type is added to keep libbpf API clean and consistent.
+
+All types and functions provided by libbpf API should have one of the
+following prefixes: ``bpf_``, ``btf_``, ``libbpf_``.
+
+System call wrappers
+--------------------
+
+System call wrappers are simple wrappers for commands supported by
+sys_bpf system call. These wrappers should go to ``bpf.h`` header file
+and map one-on-one to corresponding commands.
+
+For example ``bpf_map_lookup_elem`` wraps ``BPF_MAP_LOOKUP_ELEM``
+command of sys_bpf, ``bpf_prog_attach`` wraps ``BPF_PROG_ATTACH``, etc.
+
+Objects
+-------
+
+Another class of types and functions provided by libbpf API is "objects"
+and functions to work with them. Objects are high-level abstractions
+such as BPF program or BPF map. They're represented by corresponding
+structures such as ``struct bpf_object``, ``struct bpf_program``,
+``struct bpf_map``, etc.
+
+Structures are forward declared and access to their fields should be
+provided via corresponding getters and setters rather than directly.
+
+These objects are associated with corresponding parts of ELF object that
+contains compiled BPF programs.
+
+For example ``struct bpf_object`` represents ELF object itself created
+from an ELF file or from a buffer, ``struct bpf_program`` represents a
+program in ELF object and ``struct bpf_map`` is a map.
+
+Functions that work with an object have names built from object name,
+double underscore and part that describes function purpose.
+
+For example ``bpf_object__open`` consists of the name of corresponding
+object, ``bpf_object``, double underscore and ``open`` that defines the
+purpose of the function to open ELF file and create ``bpf_object`` from
+it.
+
+Another example: ``bpf_program__load`` is named for corresponding
+object, ``bpf_program``, that is separated from other part of the name
+by double underscore.
+
+All objects and corresponding functions other than BTF related should go
+to ``libbpf.h``. BTF types and functions should go to ``btf.h``.
+
+Auxiliary functions
+-------------------
+
+Auxiliary functions and types that don't fit well in any of categories
+described above should have ``libbpf_`` prefix, e.g.
+``libbpf_get_error`` or ``libbpf_prog_type_by_name``.
+
+libbpf ABI
+==========
+
+libbpf can be both linked statically or used as DSO. To avoid possible
+conflicts with other libraries an application is linked with, all
+non-static libbpf symbols should have one of the prefixes mentioned in
+API documentation above. See API naming convention to choose the right
+name for a new symbol.
+
+Symbol visibility
+-----------------
+
+libbpf follow the model when all global symbols have visibility "hidden"
+by default and to make a symbol visible it has to be explicitly
+attributed with ``LIBBPF_API`` macro. For example:
+
+.. code-block:: c
+
+        LIBBPF_API int bpf_prog_get_fd_by_id(__u32 id);
+
+This prevents from accidentally exporting a symbol, that is not supposed
+to be a part of ABI what, in turn, improves both libbpf developer- and
+user-experiences.
+
+ABI versionning
+---------------
+
+To make future ABI extensions possible libbpf ABI is versioned.
+Versioning is implemented by ``libbpf.map`` version script that is
+passed to linker.
+
+Version name is ``LIBBPF_`` prefix + three-component numeric version,
+starting from ``0.0.1``.
+
+Every time ABI is being changed, e.g. because a new symbol is added or
+semantic of existing symbol is changed, ABI version should be bumped.
+
+For example, if current state of ``libbpf.map`` is:
+
+.. code-block::
+        LIBBPF_0.0.1 {
+        	global:
+                        bpf_func_a;
+                        bpf_func_b;
+        	local:
+        		\*;
+        };
+
+, and a new symbol ``bpf_func_c`` is being introduced, then
+``libbpf.map`` should be changed like this:
+
+.. code-block::
+        LIBBPF_0.0.1 {
+        	global:
+                        bpf_func_a;
+                        bpf_func_b;
+        	local:
+        		\*;
+        };
+        LIBBPF_0.0.2 {
+                global:
+                        bpf_func_c;
+        } LIBBPF_0.0.1;
+
+, where new version ``LIBBPF_0.0.2`` depends on the previous
+``LIBBPF_0.0.1``.
+
+Format of version script and ways to handle ABI changes, including
+incompatible ones, described in details in [1].

+<h3>Points to note:</h3>
+<ul>
+<li>The top level is a command name (comm)</li>
+<li>The next level is a thread (pid:tid)</li>
+<li>Subsequent levels are functions</li>
+<li>'Count' is the number of calls</li>
+<li>'Time' is the elapsed time until the function returns</li>
+<li>Percentages are relative to the level above</li>
+<li>'Branch Count' is the total number of branches for that function and all functions that it calls
+</ul>
+<h3>Find</h3>
+Ctrl-F displays a Find bar which finds function names by either an exact match or a pattern match.
+The pattern matching symbols are ? for any character and * for zero or more characters.
+<h2 id=allbranches>1.2 All branches</h2>
+The All branches report displays all branches in chronological order.
+Not all data is fetched immediately. More records can be fetched using the Fetch bar provided.
+<h3>Disassembly</h3>
+Open a branch to display disassembly. This only works if:
+<ol>
+<li>The disassembler is available. Currently, only Intel XED is supported - see <a href=#xed>Intel XED Setup</a></li>
+<li>The object code is available. Currently, only the perf build ID cache is searched for object code.
+The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR.
+One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu),
+or alternatively, set environment variable PERF_KCORE to the kcore file name.</li>
+</ol>
+<h4 id=xed>Intel XED Setup</h4>
+To use Intel XED, libxed.so must be present.  To build and install libxed.so:
+<pre>
+git clone https://github.com/intelxed/mbuild.git mbuild
+git clone https://github.com/intelxed/xed
+cd xed
+./mfile.py --share
+sudo ./mfile.py --prefix=/usr/local install
+sudo ldconfig
+</pre>
+<h3>Find</h3>
+Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
+Refer to Python documentation for the regular expression syntax.
+All columns are searched, but only currently fetched rows are searched.
+<h2 id=selectedbranches>1.3 Selected branches</h2>
+This is the same as the <a href=#allbranches>All branches</a> report but with the data reduced
+by various selection criteria. A dialog box displays available criteria which are AND'ed together.
+<h3>1.3.1 Time ranges</h3>
+The time ranges hint text shows the total time range. Relative time ranges can also be entered in
+ms, us or ns. Also, negative values are relative to the end of trace.  Examples:
+<pre>
+	81073085947329-81073085958238	From 81073085947329 to 81073085958238
+	100us-200us		From 100us to 200us
+	10ms-			From 10ms to the end
+	-100ns			The first 100ns
+	-10ms-			The last 10ms
+</pre>
+N.B. Due to the granularity of timestamps, there could be no branches in any given time range.
+<h1 id=tables>2. Tables</h1>
+The Tables menu shows all tables and views in the database. Most tables have an associated view
+which displays the information in a more friendly way. Not all data for large tables is fetched
+immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted,
+but that can be slow for large tables.
+<p>There are also tables of database meta-information.
+For SQLite3 databases, the sqlite_master table is included.
+For PostgreSQL databases, information_schema.tables/views/columns are included.
+<h3>Find</h3>
+Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
+Refer to Python documentation for the regular expression syntax.
+All columns are searched, but only currently fetched rows are searched.
+<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous
+will go to the next/previous result in id order, instead of display order.
