-
- + Multiple security improvements and fixes in packet parsing routines, DNS
- caching, and TCP sequence number and ID generation.
- + Disable NBNS and LLMNR by default.
- + Add TCP hang protection by default.
-
-We thank Ori Karliner of Zimperium zLabs Team for reporting these issues.
-
-Changes between 160908 and 160919 releases:
-
- + Add a NULL check before attempting to close the DHCP socket. [Prior to
- 160823 the IP task closed the DHCP socket by calling a public API function
- - which checked for the socket being NULL. This was changed to call a
- local private function, which did not have a NULL check, in place of the
- public API function.]
- + Various [internal only] naming changes to better comply with the FreeRTOS
- naming conventions.
- + Improvements to the Zynq network driver. DMA transmission buffers now use
- a counting semaphore. When all TX-buffers are in-use, the IP-task will
- block momentarily until a TX-buffer becomes available.
- + Experimental implementation of the TCP window scaling protocol. The
- scaling option will always be offered, at least with a factor 1. If the
- TCP sliding window size becomes more than 64KB, the factor will increase
- automatically.
- + ipconfigETHERNET_MINIMUM_PACKET_BYTES is now applied for every protocol:
- TCP, UDP, and ARP.
- + Updated the Zynq project to use BufferAllocation_1.c rather than
- BufferAllocation_2.c - which is a requirement with its current
- configuration (due to the alignment requirements on the combined cache and
- DMA configuration).
-
-Changes between 160823 and 160908 releases:
-
- + Use ipconfigZERO_COPY_TX_DRIVER as the xReleaseAfterSend() parameter where
- prvTCPReturnPacket() is called in prvSendData() to prevent unnecessary
- copying of data.
- + Remove the use of the uxGetRxEventCount variable, which was used to give
- priority to incoming messages, but could result in the IP task starving
- application tasks of processing time.
-
-Changes between 160112 and 160823 releases
-
- NOTE: The 160908 release is a maintenance release for the 160112 single
- interface labs release - not a release of the current development branch.
-
- + Various minor stability enhancements, including the ability to work with
- configTICK_RATE_HZ set to less than 1KHz, closing DHCP sockets directly
- rather than via FreeRTOS_closesocket(), and better handling of unknown
- TCP packets before an IP address has been assigned.
- + ipBUFFER_PADDING is now configurable through the ipconfigBUFFER_PADDING
- constant to improve network buffer alignment handling capabilities (expert
- users/driver writers only).
- + Multiple improvements to the FTP server, including to how read only and
- zero length files are handled.
- + ipconfigFTP_HAS_USER_PROPERTIES_HOOK (to allow each user to have a
- different root directory and access rights) and
- ipconfigHTTP_HAS_HANDLE_REQUEST_HOOK (to handle AJAX style data)
- introduced, although these are not yet fully tested and the constant names
- are likely to change.
- + Introduce ipconfigHAS_TX_CRC_OFFLOADING.
- + ipconfigUSE_DHCP_HOOK is now called ipconfigUSE_DHCP_HOOK, and the name
- of the callback function has also changed. See the web documentation for
- details.
- + ipconfigTCP_RX_BUF_LEN is now ipconfigTCP_RX_BUFFER_LENGTH, and
- ipconfigTCP_TX_BUF_LEN is now ipconfigTCP_TX_BUFFER_LENGTH, which is
- actually how they have always been documented.
- + Added example TFTP server capable of receiving (not sending) files.
- Intended for bootloader type functionality.
- + Various variable name changes for consistency (mainly ensuring UDP, TCP,
- DNS, etc. always use the same case letters, and type prefixes are correct).
- + Various minor edits to improve types used by internal variables.
- + Simplified mapping of standard library functions to their Visual Studio
- equivalents.
- + Improve robustness of network drivers.
- + Introduce pxResizeNetworkBufferWithDescriptor().
- + Removed obsolete FreeRTOSIPConfig.h constants from
- FreeRTOSIPConfigDefaults.h.
- + Added additional asserts() - predominantly to catch incorrect structure
- packing.
-
-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
- "ping RTOSDemo".
-
-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.
