The formats allowed by the pcap_open() are the following:

- file://path_and_filename [opens a local file]
|

- rpcap://devicename [opens the selected device devices available on the local host, without using the RPCAP protocol]
|
||||
- rpcap://host/devicename [opens the selected device available on a remote host]
|
||||
- rpcap://host:port/devicename [opens the selected device available on a remote host, using a non-standard port for RPCAP]
|
||||
- adaptername [to open a local adapter; kept for compability, but it is strongly discouraged]
|
||||
- (NULL) [to open the first local adapter; kept for compability, but it is strongly discouraged]
|
||||
|
||||
The formats allowed by the pcap_findalldevs_ex() are the following:
|
||||
- file://folder/ [lists all the files in the given folder]
|
||||
- rpcap:// [lists all local adapters]
|
||||
- rpcap://host:port/ [lists the devices available on a remote host]
|
||||
|
||||
Referring to the 'host' and 'port' paramters, they can be either numeric or literal. Since
|
||||
IPv6 is fully supported, these are the allowed formats:
|
||||
|
||||
- host (literal): e.g. host.foo.bar
|
||||
- host (numeric IPv4): e.g. 10.11.12.13
|
||||
- host (numeric IPv4, IPv6 style): e.g. [10.11.12.13]
|
||||
- host (numeric IPv6): e.g. [1:2:3::4]
|
||||
- port: can be either numeric (e.g. '80') or literal (e.g. 'http')
|
||||
|
||||
Here you find some allowed examples:
|
||||
- rpcap://host.foo.bar/devicename [everything literal, no port number]
|
||||
- rpcap://host.foo.bar:1234/devicename [everything literal, with port number]
|
||||
- rpcap://10.11.12.13/devicename [IPv4 numeric, no port number]
|
||||
- rpcap://10.11.12.13:1234/devicename [IPv4 numeric, with port number]
|

- rpcap://[10.11.12.13]:1234/devicename [IPv4 numeric with IPv6 format, with port number]
|
||||
- rpcap://[1:2:3::4]/devicename [IPv6 numeric, no port number]
|

- rpcap://[1:2:3::4]:1234/devicename [IPv6 numeric, with port number]

* TRC_CFG_USE_SEPARATE_USER_EVENT_BUFFER
|
||||
*
|
||||
* Macro which should be defined as an integer value.
|
||||
*
|
||||
* Set TRC_CFG_USE_SEPARATE_USER_EVENT_BUFFER to 1 to enable the
|
||||
* separate user event buffer (UB).
|
||||
* In this mode, user events are stored separately from other events,
|
||||
* e.g., RTOS events. Thereby you can get a much longer history of
|
||||
* user events as they don't need to share the buffer space with more
|
||||
* frequent events.
|
||||
*
|
||||
* The UB is typically used with the snapshot ring-buffer mode, so the
|
||||
* recording can continue when the main buffer gets full. And since the
|
||||
* main buffer then overwrites the earliest events, Tracealyzer displays
|
||||
* "Unknown Actor" instead of task scheduling for periods with UB data only.
|
||||
*
|
||||
* In UB mode, user events are structured as UB channels, which contains
|
||||
* a channel name and a default format string. Register a UB channel using
|
||||
* xTraceRegisterUBChannel.
|
||||
*
|
||||
* Events and data arguments are written using vTraceUBEvent and
|
||||
* vTraceUBData. They are designed to provide efficient logging of
|
||||
* repeating events, using the same format string within each channel.
|
||||
*
|
||||
* Examples:
|
||||
*
|
||||
* traceString chn1 = xTraceRegisterString("Channel 1");
|
||||
* traceString fmt1 = xTraceRegisterString("Event!");
|
||||
* traceUBChannel UBCh1 = xTraceRegisterUBChannel(chn1, fmt1);
|
||||
*
|
||||
* traceString chn2 = xTraceRegisterString("Channel 2");
|
||||
* traceString fmt2 = xTraceRegisterString("X: %d, Y: %d");
|
||||
* traceUBChannel UBCh2 = xTraceRegisterUBChannel(chn2, fmt2);
|
||||
*
|
||||
* // Result in "[Channel 1] Event!"
|
||||
* vTraceUBEvent(UBCh1);
|
||||
*
|
||||
* // Result in "[Channel 2] X: 23, Y: 19"
|
||||
* vTraceUBData(UBCh2, 23, 19);
|
||||
*
|
||||
* You can also use the other user event functions, like vTracePrintF.
|
||||
* as they are then rerouted to the UB instead of the main event buffer.
|
||||
* vTracePrintF then looks up the correct UB channel based on the
|
||||
* provided channel name and format string, or creates a new UB channel
|
||||
* if no match is found. The format string should therefore not contain
|
||||
* "random" messages but mainly format specifiers. Random strings should
|
||||
* be stored using %s and with the string as an argument.
|
||||
*
|
||||
* // Creates a new UB channel ("Channel 2", "%Z: %d")
|
||||
* vTracePrintF(chn2, "%Z: %d", value1);
|
||||
*
|
||||
* // Finds the existing UB channel
|
||||
* vTracePrintF(chn2, "%Z: %d", value2);

Changes since the 160112 release
|
||||
|
||||
FTP : now has ipconfigFTP_HAS_USER_PROPERTIES_HOOK
|
||||
Each user can be assigned a different root directory and different access rights.
|
||||
Read-only access for FTP is now possible.
|
||||
|
||||
Adapted to comply a bit more to MISRA rules.
|
||||
The introduction of unsigned true/false, e.g. pdTRUE_UNSIGNED.
|
||||
|
||||
'ipBUFFER_PADDING' now configurable (expert option).
|
||||
|
||||
Added ipconfigFTP_HAS_USER_PROPERTIES_HOOK.
|
||||
ipconfigHAS_TX_CRC_OFFLOADING
|
||||
Improve support for read only file systems in the FTP server.
|
||||
|
||||
Depending on priorities: FreeRTOS_accept() could fail if the priority of the application task is higher than the priority of the IP-task. Now with a higher priority FreeRTOS_accept() will still work correctly.
|
||||
|
||||
Depending on the tick rate: A TCP socket could freeze (stop working) when the FreeRTOS tick rate was lower than 1,000 Hz. Now also tested with 100 Hz.
|
||||
|
||||
When "ipconfigZERO_COPY_TX_DRIVER = 0", sometime xNetworkInterfaceOutput() was called to send out a small TCP ACK. The network buffer would refer to space on the TCP socket ("lastPacket"), which was not 8-byte aligned. Repaired: from now on the buffer will have a proper 8-byte alignment.
|
||||
|
||||
"#if __cplusplus" is been replaced with the more proper test "#ifdef __cplusplus".
|
||||
|
||||
|
||||
|
||||
These are the recent commits:
|
||||
565 Initial check-in of +TCP/multi
|
||||
566 LPC18xx : updated and re-tested the TCP and FAT drivers
|
||||
569 +TCP : protocols: Added an installable application hook: "CheckDrivesHook"
|
||||
570 +TCP : will now work properly when configTICK_RATE_HZ < 1000
|
||||
571 +TCP : will now work properly when configTICK_RATE_HZ < 1000
|
||||
572 +TCP : FreeRTOS_recvfrom now recognises "FREERTOS_MSG_PEEK"
|
||||
573 +FAT : Zynq : writing may fail if it goes too fast. Introduced pauses but not yet satisfied
|
||||
|
||||
|
||||
Changes between 160112 and 160111 releases
|
||||
|
||||
+ Updated the STM32 network driver so checksums are calculated by the
|
||||
hardware.
|
||||
+ Implemented a simple "quit" command in the TCP command console.
|
||||
|
||||
Changes between 150825 and 160111 releases
|
||||
|
||||
+ New device support: Demo applications and example drivers are provided
|
||||
for Atmel SAM4E and ST STM32F4 microcontrollers.
|
||||
+ Various updates to improve compliance with the FreeRTOS coding standard.
|
||||
+ Added a command console example that uses TCP/IP for input and output (the
|
||||
pre-existing command console example uses UDP/IP).
|
||||
+ Updated the UDP logging example so it will send log messages to the local
|
||||
UDP broadcast address if a specific IP address is not provided. This
|
||||
simplifies configuration, but note not all switches and routers will pass
|
||||
broadcast messages.
|
||||
+ Add TCP echo client and TCP echo server examples to the Zynq demo.
|
||||
+ Minor updates to the Zynq network driver.
|
||||
+ Update the Zynq project to use version 2015.4 of the Xilinx SDK.
|
||||
+ Introduce FreeRTOS_SignalSocket(), which can be used to interrupt a task
|
||||
that is blocked while reading from a socket ( FreeRTOS_recv[from] ).
|
||||
+ Make use of FreeRTOS_SignalSocket() in the FTP and HTTP servers.
|
||||
+ Major updates to the NTP client, although this is not included in any of
|
||||
the pre-configured demo applications yet.
|
||||
+ Added support for DHCP zero pad option.
|
||||
+ Added uxGetMinimumIPQueueSpace(), a function to monitor the minimum amount
|
||||
of space on the message queue.
|
||||
+ Better handling of zero length files in the FTP server.
|
||||
+ Fixed a bug reported by Andrey Ivanov from swissEmbedded that affects
|
||||
users of 'ipconfigZERO_COPY_TX_DRIVER'.
|
||||
|
||||
|
||||
Changes between 150825 150825 (?)
|
||||
|
||||
+ Added xApplicationDHCPUserHook() so a user defined hook will be
|
||||
called at certain points in the DHCP process if
|
||||
ipconfigDHCP_USES_USER_HOOK is set to 1.
|
||||
+ Added FreeRTOS_get_tx_head() to improve TCP zero copy behaviour - for
|
||||
expert use only.
|
||||
+ RST is no longer sent if only the ACK flag is set.
|
||||
+ Previously, an immediate ACK was only sent when buffer space was
|
||||
exhausted. Now, to improve performance, it is possible to send an
|
||||
immediate ACK earlier - dependent on the ipconfigTCP_ACK_EARLIER_PACKET
|
||||
setting.
|
||||
+ LLMNR and NBNS requests can now be sent to locate other devices -
|
||||
previously these protocols would only be replied to, not generated.
|
||||
+ Added Auto-IP functionality (still in test) in case DHCP fails. Dependent
|
||||
on the ipconfigDHCP_FALL_BACK_LINK_LAYER_ADDRESS and
|
||||
ipconfigARP_USE_CLASH_DETECTION settings.
|
||||
+ Added NTP code and demo.
|
||||
+ FTP can now STOR and RETR zero-length files.
|
||||
+ Added LLMNR demo to Win32 demo - so now the Win32 responds to

|

|
||||
Changes between 141019 and 150825
|
||||
|
||||
+ Added FTP server, which uses the new FreeRTOS+FAT component.
|
||||
+ Added basic HTTP server, which uses the new FreeRTOS+FAT component.
|
||||
+ Multiple definitions that are now common with FreeRTOS+FAT have been moved
|
||||
into FreeRTOS's ProjDefs.h header file, and so prefixed with 'pd'.
|
||||
+ Introduced ipconfigZERO_COPY_TX_DRIVER, which defines who is responsible
|
||||
for freeing a buffer sent to to the MAC driver for transmission, and
|
||||
facilitates the development of zero copy drivers.
|
||||
+ Introduced the FREERTOS_MSG_DONTWAIT flag. The flag can be used as a
|
||||
simpler and faster alternative to using FreeRTOS_setsockopt() to set the
|
||||
send or receive timeout to 0.
|
||||
+ A few functions that were previously all lower case are now mixed case, as
|
||||
lower case function names are only used when they are equivalent to a
|
||||
a Berkeley sockets API function of the same name.
|
||||
+ Introduced uxGetMinimumFreeNetworkBuffers() to return the minimum number
|
||||
of network buffers that have ever existed since the application started
|
||||
executing.
|
||||
+ Introduce ipconfigETHERNET_MINIMUM_PACKET_BYTES to allow the application
|
||||
writer to set their own minimum buffer size should the hardware not be
|
||||
capable of padding under-sized Ethernet frames.
|
||||
+ vNetworkBufferRelease() renamed vReleaseNetworkBuffer() - just for
|
||||
consistency with the names of other functions in the same file.
|
||||
+ Grouped DHCP status data into a structure.
|
||||
+ DHCP is now tried both with and without the broadcast flag.
|
||||
+ Replaced occurrences of configASSERT_VOID() with configASSERT().
|
||||
+ ipconfigDNS_USE_CALLBACKS introduced to allow FreeRTOS_gethostbyname() to
|
||||
be used without blocking.
|
||||
+ Fix: LLMNR and NBNS behaviour when the reply is in a larger buffer than the
|
||||
request, and BufferAllocation_2 was used.
|
||||
+ Introduced ipMAX_IP_TASK_SLEEP_TIME to allow the application writer to
|
||||
override the default value of 10 seconds.
|
||||
+ Fix: Correct error in *pxUDPPayloadBuffer_to_NetworkBuffer().
|
||||
+ FreeRTOS_recv() now recognises the FREERTOS_ZERO_COPY flag, which, when
|
||||
set, the void *pvBuffer parameter is interpreted as void **pvBuffer.
|
||||
+ FreeRTOS_listen() now returns an error code. Previously it always
|
||||
returned 0.
|
||||
+ Fix: Previously if a listening socket was reused, and a connection
|
||||
failed, the TCP/IP stack closed the socket, now the socket is correctly
|
||||
left unclosed as it is owned by the application.
|
||||
+ Various other formatting and minor fix alterations.
