-Building lwIP
-=============
-
-lwIP uses a CMake based build system.
-
-The CMake files in this project are designed to
-be included into your own CMake files. They are
-mainly variable definitions containing a list of
-source files and predefined static libraries to
-be linked against application code.
-
-1) lwIP sources:
-   src/Filelists.cmake provides file lists containing
-   the lwIP core library.
-   The file also contains two static libraries, lwipcore
-   and lwipallapps, where you can link your app against.
-   This is the file that is useful to all lwIP users.
-
-2) Example applications:
-   contrib/Filelists.cmake provides several file lists
-   containing the example applications.
-   The file also contains several static libraries
-   for these example apps.
-   This file is only useful for you, if you can use one
-   of the examples in your application, which is normally
-   not the case.
-
-3) OS/platform port:
-   Usually the OS port needs to be provided by the user.
-   If a port to Linux, Windows or MacOS is useful for
-   you, you can use
-   contrib/ports/{win32, unix}/Filelists.cmake
-   that contains file lists and libraries for
-   these operating systems.
-
-VARIABLES
-=========
-In all cases, you need to provide two variables.
-
-"LWIP_DIR" pointing to the lwIP directory
-Example:
-set(LWIP_DIR ${CMAKE_CURRENT_SOURCE_DIR}/externals/lwip)
-
-"LWIP_INCLUDE_DIRS" that contains the include base paths
- for lwIP itself (${LWIP_DIR}/src/include)
- for lwIP contrib if you use it (${LWIP_DIR}/contrib)
- to a directory containing an OS port
- to a directory containing lwipopts.h
-
-Example:
-set (LWIP_INCLUDE_DIRS
-    "${LWIP_DIR}/src/include"
-    "${LWIP_DIR}/contrib"
-    "${LWIP_DIR}/contrib/ports/unix/port/include"
-    "${LWIP_DIR}/contrib/examples/example_app"
-)
-
-Putting it all together
-=======================
-To get a working application, your CMake system
-needs to provide the variables described above, e.g.
-set (LWIP_DIR <path to lwip sources>)
-set (LWIP_INCLUDE_DIRS
-    "${LWIP_DIR}/src/include"
-    "${LWIP_DIR}/contrib"
-    "<path to my port>/include"
-    "<path to lwipopts.h>"
-)
-
-You may add some defines:
-set (LWIP_DEFINITIONS LWIP_DEBUG=1)
-
-Then include the filelists you need:
-include(${LWIP_DIR}/src/Filelists.cmake)
-include(${LWIP_DIR}/contrib/Filelists.cmake)
-
-Then, declare you executable:
-add_executable(my_app <my source files> <my lwip port files>)
-
-Add lwIP include dirs to your app:
-target_include_directories(my_app PRIVATE ${LWIP_INCLUDE_DIRS})
-
-Link your app against the lwIP libs from the filelists you need:
-target_link_libraries(my_app lwipcontribapps lwipallapps lwipcore)
-
-Working example
-===============
-Working build examples can be found in the
-contrib/ports/{win32, unix}/example_app
-subdirectory.
-To use them, create a build directory and call cmake with
-the lwIP root dir:
-
- mkdir build
- cd build
- cmake ..
- cmake --build .
-
-The CMakeLists.txt will autoselect the correct port
-for your system (supported: Linux, Windows, Darwin).
-
-To configure the example app to your needs, you need to copy the file
-    contrib/examples/example_app/lwipcfg.h.example
-to
-    contrib/examples/example_app/lwipcfg.h
-and edit to your needs.
-
-Makefile based build system
-===========================
-lwIP also maintains file lists for Makefile-based
-build systems. Look for Filelists.mk files
-in the source tree. We try to maintain them,
-but lwIP's mainly focused build system is CMake.
-
-MS Visual Studio
-================
-lwIP also provides basic support for MSVS in the win32 port
-folder under 'msvc'. We try to maintain these files,
-but lwIP's mainly focused build system is CMake.

 INTRODUCTION

-lwIP is a small independent implementation of the TCP/IP protocol suite.
+lwIP is a small independent implementation of the TCP/IP protocol
+suite that has been developed by Adam Dunkels at the Computer and
+Networks Architectures (CNA) lab at the Swedish Institute of Computer
+Science (SICS).

 The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
 while still having a full scale TCP. This making lwIP suitable for use
 in embedded systems with tens of kilobytes of free RAM and room for
 around 40 kilobytes of code ROM.

-lwIP was originally developed by Adam Dunkels at the Computer and Networks
-Architectures (CNA) lab at the Swedish Institute of Computer Science (SICS)
-and is now developed and maintained by a worldwide network of developers.

 (git master)

  * [Enter new changes just after this line - do not remove this line]
-  * The eth_addr_cmp and ip_addr_cmp set of functions have been renamed to eth_addr_eq, ip_addr_eq
-    and so on, since they return non-zero on equality. Macros for the old names exist.
-  * The sio_write function used by PPP now takes the data argument as const.
-  * The prev field in the snmp_varbind struct has been removed.
-
-(2.2.0)
-
-  ++ Repository changes:
-
-  * The contrib repository has been added into the main repository in the subdirectory 'contrib'
-    (the old contrib repository remains online for reference but is not used any more)
-
-(2.1.0)
-
-  ++ Application changes:
-
-  * Use the new altcp API for seamless TLS integration into existing TCP applications (see changelog)
-  * TCP only kills existing connections with a LOWER priority than the one currently being opened.
-    Previous implementations also kill existing connections of the SAME priority.
-  * ip4_route_src: parameter order is reversed: ip4_route_src(dest, src) -> ip4_route_src(src, dest)
-    to make parameter order consistent with other ip*_route*() functions.
-    Same also applies to LWIP_HOOK_IP4_ROUTE_SRC() parameter order.
-  * pbuf API: pbuf->type (an u8_t holding the enum 'pbuf_type') has changed to only hold a
-    description of the pbuf (e.g. data following pbuf struct, data volatile, allocation
-    source heap/pool/etc.). As a consequence, applications can't test pbuf->type any more.
-    Use pbuf_match_type(pbuf, type) instead.
-  * socket API: according to the standard, SO_ERROR now only returns asynchronous errors.
-    All other/normal/synchronous errors are (and always were) available via 'errno'.
-    LWIP_SOCKET_SET_ERRNO has been removed - 'errno' is always set - and required!
-  * httpd LWIP_HTTPD_CGI_SSI: httpd_cgi_handler() has an additional parameter "struct fs_file *"
-
-  ++ Port changes:
-
-  * tcpip_trycallback() was renamed to tcpip_callbackmsg_trycallback() to avoid confusion
-    with tcpip_try_callback()
-  * compatibility headers: moved from 'src/include/posix' to 'src/include/compat/posix',
-    'src/include/compat/stdc' etc.
-  * The IPv6 implementation now supports address scopes. (See LWIP_IPV6_SCOPES documentation
-    and ip6_zone.h for more documentation)
-  * LWIP_HOOK_DHCP_APPEND_OPTIONS() has changed, see description in opt.h (options_out_len is not
-    available in struct dhcp any more)
-  * Added debug helper asserts to ensure threading/locking requirements are met (define
-    LWIP_MARK_TCPIP_THREAD() and LWIP_ASSERT_CORE_LOCKED()).
-  * Added sys_mbox_trypost_fromisr() and tcpip_callbackmsg_trycallback_fromisr()
-    These can be used to post preallocated messages from an ISR to the tcpip thread
-    (e.g. when using FreeRTOS)

-A simple routing table implementation for addition, deletion and lookup of IPv6 routes. 
-
-APIs are:
-1) s8_t ip6_add_route_entry(struct ip6_prefix *ip6_prefix,
-                            struct netif *netif,
-                            ip6_addr_t *gateway,
-                            s8_t *index);
-
-2) err_t ip6_remove_route_entry(struct ip6_prefix *ip6_prefix);
-
-3) s8_t ip6_find_route_entry(ip6_addr_t *ip6_dest_addr);
-
-4) struct netif *ip6_static_route(ip6_addr_t *src, ip6_addr_t *dest);
-
-5) ip6_addr_t *ip6_get_gateway(struct netif *netif, ip6_addr_t *dest);
-
-6) struct ip6_route_entry *ip6_get_route_table(void);
-
-For route lookup from the table, The LWIP_HOOK_IP6_ROUTE hook in ip6_route(..) of ip6.c
-could be assigned to the ip6_static_route() API of this implementation to return the 
-appropriate netif.
-
-- The application can add routes using the API ip6_add_route_entry(..). 
-   This API adds the ip6 prefix route into the static route table while
-   keeping all entries sorted in decreasing order of prefix length.
-   Subsequently, a linear search down the list can be performed to retrieve a
-   matching route entry for a Longest Prefix Match.
-   The prefix length is expected to be at an 8-bit boundary. While this is 
-   a limitation, it would serve most practical purposes.
-
-- The application can remove routes using the API ip6_remove_route_entry(..).
-
-- The application can find a route entry for a specific address using the 
-   ip6_find_route_entry() function which returns the index of the found entry. 
-   This is used internally by the route lookup function ip6_static_route() API.
-
-- To fetch the gateway IPv6 address for a specific destination IPv6 
-   address and target netif, the application can call ip6_get_gateway(..).
-   This API could be assigned to the LWIP_HOOK_ND6_GET_GW() if a gateway has
-   been added as part of the ip6_add_route_entry().
-
-- To fetch a pointer to the head of the table, the application can call 
-   ip6_get_route_table().

-/**
- * @file
- *
- * Reference implementation of the TCP ISN algorithm standardized in RFC 6528.
- * Produce TCP Initial Sequence Numbers by combining an MD5-generated hash
- * based on the new TCP connection's identity and a stable secret, with the
- * current time at 4-microsecond granularity.
- *
- * Specifically, the implementation uses MD5 to compute a hash of the input
- * buffer, which contains both the four-tuple of the new TCP connection (local
- * and remote IP address and port), as well as a 16-byte secret to make the
- * results unpredictable to external parties.  The secret must be given at
- * initialization time and should ideally remain the same across system
- * reboots.  To be sure: the spoofing-resistance of the resulting ISN depends
- * mainly on the strength of the supplied secret!
- *
- * The implementation takes 32 bits from the computed hash, and adds to it the
- * current time, in 4-microsecond units.  The current time is computed from a
- * boot time given at initialization, and the current uptime as provided by
- * sys_now().  Thus, it assumes that sys_now() returns a time value that is
- * relative to the boot time, i.e., that it starts at 0 at system boot, and
- * only ever increases monotonically.
- *
- * For efficiency reasons, a single MD5 input buffer is used, and partially
- * filled in at initialization time.  Specifically, of this 64-byte buffer, the
- * first 36 bytes are used for the four-way TCP tuple data, followed by the
- * 16-byte secret, followed by 12-byte zero padding.  The 64-byte size of the
- * buffer should achieve the best performance for the actual MD5 computation.
- *
- * Basic usage:
- *
- * 1. in your lwipopts.h, add the following lines:
- *
- *    #include <lwip/arch.h>
- *    struct ip_addr;
- *    u32_t lwip_hook_tcp_isn(const struct ip_addr *local_ip, u16_t local_port,
- *      const struct ip_addr *remote_ip, u16_t remote_port);
- *   "#define LWIP_HOOK_TCP_ISN lwip_hook_tcp_isn";
- *
- * 2. from your own code, call lwip_init_tcp_isn() at initialization time, with
- *    appropriate parameters.

-This folder provides an example implementation of how to add custom tcp header
-options and custom socket options.
-
-It does this by implementing the (seldom used) tcp md5 signature.
-
-To enable it, add an LWIP_HOOK_FILENAME hook file, include tcp_md5.h in it and
-define these hooks:
-
-  #define LWIP_HOOK_TCP_INPACKET_PCB(pcb, hdr, optlen, opt1len, opt2, p) tcp_md5_check_inpacket(pcb, hdr, optlen, opt1len, opt2, p)
-  #define LWIP_HOOK_TCP_OPT_LENGTH_SEGMENT(pcb, internal_len)            tcp_md5_get_additional_option_length(pcb, internal_len)
-  #define LWIP_HOOK_TCP_ADD_TX_OPTIONS(p, hdr, pcb, opts)                tcp_md5_add_tx_options(p, hdr, pcb,  opts)
-  #define LWIP_HOOK_SOCKETS_SETSOCKOPT(s, sock, level, optname, optval, optlen, err) tcp_md5_setsockopt_hook(sock, level, optname, optval, optlen, err)
-
-Then, in your sockets application, enable md5 signature on a socket like this:
-
-  struct tcp_md5sig md5;
-  struct sockaddr_storage addr_remote; /* Initialize this to remote address and port */
-  memcpy(&md5.tcpm_addr, &addr_remote, sizeof(addr_remote));
-  strcpy(md5.tcpm_key, key); /* this is the md5 key per connection */
-  md5.tcpm_keylen = strlen(key);
-  if ((ret = setsockopt(sockfd, IPPROTO_TCP, TCP_MD5SIG, &md5, sizeof(md5))) < 0) {
-    perror("setsockopt TCP_MD5SIG");
-    return;
-  }
-
-After that, your connection (client) or all incoming connections (server) require
-tcp md5 signatures.

-    Microsoft ResX Schema 
-    
-    Version 2.0
-    
-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-    
-    Example:
-    
-    ... ado.net/XML headers & schema ...
-    <resheader name="resmimetype">text/microsoft-resx</resheader>
-    <resheader name="version">2.0</resheader>
-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-        <value>[base64 mime encoded serialized .NET Framework object]</value>
-    </data>
-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.

-    Microsoft ResX Schema 
-    
-    Version 2.0
-    
-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-    
-    Example:
-    
-    ... ado.net/XML headers & schema ...
-    <resheader name="resmimetype">text/microsoft-resx</resheader>
-    <resheader name="version">2.0</resheader>
-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-        <value>[base64 mime encoded serialized .NET Framework object]</value>
-    </data>
-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.

-    DESCRIPTION     "This MIB module defines the IANACharset
-                    TEXTUAL-CONVENTION.  The IANACharset TC is used to
-                    specify the encoding of string objects defined in
-                    a MIB.
-
-                    Each version of this MIB will be released based on
-                    the IANA Charset Registry file (see RFC 2978) at

-
-                    Note:  The IANACharset TC, originally defined in
-                    RFC 1759, was inaccurately named CodedCharSet.
-
-                    Note:  Best practice is to define new MIB string
-                    objects with invariant UTF-8 (RFC 3629) syntax
-                    using the SnmpAdminString TC (defined in RFC 3411)
-                    in accordance with IETF Policy on Character Sets and
-                    Languages (RFC 2277).

-        defined in 'IANA Charset Registration Procedures' (RFC 2978).
-
-        Objects of this syntax are used to specify the encoding for
-        string objects defined in one or more MIBs.  For example, the
-        prtLocalizationCharacterSet, prtInterpreterDefaultCharSetIn, and
-        prtInterpreterDefaultCharSetOut objects defined in Printer MIB.
-
-        The current list of 'charset' names and enumerated values
-        is contained in the IANA Character Set Registry at:
-
-           http://www.iana.org/assignments/character-sets
-
-        Enum names are derived from the IANA Charset Registry 'Alias'
-        fields that begin with 'cs' (for character set).

-
-         If the MAU is a 10M b/s link or fiber type (FOIRL, 10BASE-T,
-         10BASE-F), then this is equivalent to the link test fail
-         state/low light function.  For an AUI, 10BASE2, 10BASE5, or
-         10BROAD36 MAU, this indicates whether loopback is detected on
-         the DI circuit.  The value of this attribute persists between
-         packets for MAU types AUI, 10BASE5, 10BASE2, 10BROAD36, and
-         10BASEFP.
-
-         At power-up or following a reset, the Media Available state
-         will be unknown(2) for AUI, 10BASE5, 10BASE2, 10BROAD36, and
-         10BASE-FP MAUs.  For these MAUs loopback will be tested on each
-         transmission during which no collision is detected.
-         If DI is receiving input when DO returns to IDL after a
-         transmission and there has been no collision during the
-         transmission, then loopback will be detected.  The Media
-         Available state will only change during noncollided
-         transmissions for AUI, 10BASE2, 10BASE5, 10BROAD36, and
-         10BASE-FP MAUs.
-
-         For 100BASE-T2, 100BASE-T4, 100BASE-TX, 100BASE-FX,
-         100BASE-LX10, and 100BASE-BX10 PHYs the enumerations match the
-         states within the link integrity state diagram.
-         Any MAU that implements management of [IEEE802.3] Clause
-         28 Auto-Negotiation, will map remote fault indication to
-         remoteFault(5).
-
-         Any MAU that implements management of Clause 37
-         Auto-Negotiation, will map the received RF1 and RF2 bits as
-         follows: Offline maps to offline(10), Link_Failure maps to
-         remoteFault(5), and Auto-Negotiation Error maps to
-         autoNegError(11).
-
-         The value remoteFault(5) applies to 10BASE-FB remote
-         fault indication, the 100BASE-X far-end fault indication, and
-         nonspecified remote faults from a system running Clause 28
-         Auto-Negotiation.
-
-         The value remoteJabber(7), remoteLink loss(8), or remoteTest(9)
-         SHOULD be used instead of remoteFault(5) where the reason for
-         remote fault is identified in the remote signaling protocol.
-         Where a Clause 22 MII or Clause 35 GMII is present, a logic
-         one in the remote fault bit maps to the value remoteFault(5),
-         a logic zero in the link status bit maps to the enumeration
-         notAvailable(4).  The value notAvailable(4) takes precedence
-         over remoteFault(5).
-
-         For 2BASE-TL and 10PASS-TS PHYs, the value unknown(2) maps to
-         the condition where the PHY (PCS with connected PMEs) is
-         initializing, the value ready(20) maps to the condition where
-         the interface is down and at least one PME in the aggregation
-         group is ready for handshake, the value available(3) maps to
-         the condition where all the PMEs in the aggregation group are
-         up, the value notAvailable(4) maps to the condition where all
-         the PMEs in the aggregation group are down and no handshake
-         tones are detected, the value availableReduced(19) maps to the
-         condition where the interface is up, a link fault is detected
-         at the receive direction by one or more PMEs in the
-         aggregation group, but at least one PME is up and the
-         enumeration pmdLinkFault(12) maps to the condition where a link
-         fault is detected at the receive direction by all of the PMEs
-         in the aggregation group.
-
-         For 10 Gb/s the enumerations map to value of the link_fault
-         variable within the Link Fault Signaling state diagram
-         as follows: the value OK maps to the value available(3),
-         the value Local Fault maps to the value notAvailable(4),
-         and the value Remote Fault maps to the value remoteFault(5).
-         The value pmdLinkFault(12), wisFrameLoss(13),
-         wisSignalLoss(14), pcsLinkFault(15), excessiveBER(16), or
-         dxsLinkFault(17) SHOULD be used instead of the value
-         notAvailable(4), where the reason for the Local Fault state can
-         be identified through the use of the Clause 45 MDIO Interface.
-         Where multiple reasons for the Local Fault state can be
-         identified, only the highest precedence error SHOULD be
-
-         reported.  This precedence in descending order is as follows:
-
-           pxsLinkFault
-           pmdLinkFault
-           wisFrameLoss
-           wisSignalLoss
-           pcsLinkFault
-           excessiveBER
-           dxsLinkFault.
-
-         Where a Clause 45 MDIO interface is present a logic zero in
-         the PMA/PMD Receive link status bit ([IEEE802.3]
-         Section 45.2.1.2.2) maps to the value pmdLinkFault(12),
-         logic one in the LOF status bit (Section 45.2.2.10.4) maps
-         to the value wisFrameLoss(13), a logic one in the LOS
-         status bit (Section 45.2.2.10.5) maps to the value
-         wisSignalLoss, a logic zero in the PCS Receive
-         link status bit (Section 45.2.3.2.2) maps to the value
-         pcsLinkFault(15), a logic one in the 10GBASE-R PCS Latched
-         high BER status bit (Section 45.2.3.12.2) maps to the value
-         excessiveBER, a logic zero in the DTE XS receive link status
-         bit (Section 45.2.5.2.2) maps to the value dxsLinkFault(17)
-         and a logic zero in the PHY XS transmit link status bit
-         (Section 45.2.4.2.2) maps to the value pxsLinkFault(18).

Joel Cunningham	c31bd404e2	Fix unit test with assumed congestion avoidance test_tcp_fast_rexmit_wraparound correctness relied on the congestion window being in congestion avoidance so that only a single TCP_MSS segment is sent upon ACKing the first segment. It's not known whether the test was relying tcp_alloc() to set ssthresh to 0 and thus start in congestion avoidance or if the test was working by accident until changes in `b90a54f989` This fixes the test by enforcing the requirement of starting in congestion avoidance Signed-off-by: goldsimon <goldsimon@gmx.de> (cherry picked from commit `8bf402fd67`)	2017-03-13 09:14:38 +01:00

David van Moolenbroek	66db517a28	tcp: do not keep sending SYNs when getting ACKs If a locally generated TCP SYN packet is replied to with an ACK packet, lwIP immediately sends a RST packet followed by resending the SYN packet. This is expected, but on loopback interfaces the resent SYN packet may immediately get another ACK reply, typically when the other endpoint is in TIME_WAIT state (which ignores the RSTs). The result is an endless loop of SYN, ACK, RST packets. This patch applies the normal SYN retransmission limit in this scenario, such that the endless loop is limited to a brief storm. (cherry picked from commit `5827c168c2`)	2017-03-13 09:14:22 +01:00
Joel Cunningham	2452bc9336	bug #50476 : initialize ssthresh to TCP_SND_BUF This commit changes ssthresh to be the largest effective congestion window (amount of in-flight data). This follows the guidance of RFC 5681 which recommends setting ssthresh arbitrarily high. LwIP was previously using the receive window value at the end of the 3-way handshake and in the case of an active open where the receiver used window scaling and/or window auto-tuning, this resulted in a very small ssthresh value even though the window ramped up once the connection was established (cherry picked from commit `b90a54f989`)	2017-03-13 09:13:41 +01:00
Sylvain Rochet	2848b17e80	PPP: remove unused and confusing return values other than ERR_OK for ppp_connect and ppp_listen User should not use ppp_connect or ppp_listen return value to retry later, it must wait for the callback to be called. This is primarily done this way to have a consistent behavior with and without the holdoff feature. Remove returned error value from PPP link level API connect and listen callbacks because we are not using them anymore, then make ppp_connect or ppp_listen to always return ERR_OK, thus we are not breaking the PPP user API. We don't need the return code here, all PPP link level drivers can't fail at all (e.g. PPPoS) or retry if necessary (PPPoE and PPPoL2TP). (cherry picked from commit `e16d10ade6`)	2017-03-13 09:13:17 +01:00

David van Moolenbroek	0a3e4cd10e	tcp: fix accept event on closed listening PCBs If LWIP_CALLBACK_API is not defined, but TCP_LISTEN_BACKLOG is, then the LWIP_EVENT_ACCEPT TCP event may be triggered for closed listening sockets. This case is just as disastrous for the event API as it is for the callback API, as there is no way for the event hook to tell whether the listening PCB is still around. Add the same protection against this case for TCP_LISTEN_BACKLOG as was already in place for LWIP_CALLBACK_API. Also remove one NULL check for LWIP_CALLBACK_API that had already become redundant for all callers, making the TCP_EVENT_ACCEPT code for that callback wrapper more in line with the rest of the wrappers.
