-Changes between 160919 and 180821 releases:\r
-\r
- + Multiple security improvements and fixes in packet parsing routines, DNS\r
- caching, and TCP sequence number and ID generation.\r
- + Disable NBNS and LLMNR by default.\r
- + Add TCP hang protection by default.\r
-\r
-We thank Ori Karliner of Zimperium zLabs Team for reporting these issues.\r
-\r
-Changes between 160908 and 160919 releases:\r
-\r
- + Add a NULL check before attempting to close the DHCP socket. [Prior to\r
- 160823 the IP task closed the DHCP socket by calling a public API function\r
- - which checked for the socket being NULL. This was changed to call a\r
- local private function, which did not have a NULL check, in place of the\r
- public API function.]\r
- + Various [internal only] naming changes to better comply with the FreeRTOS\r
- naming conventions.\r
- + Improvements to the Zynq network driver. DMA transmission buffers now use\r
- a counting semaphore. When all TX-buffers are in-use, the IP-task will\r
- block momentarily until a TX-buffer becomes available.\r
- + Experimental implementation of the TCP window scaling protocol. The\r
- scaling option will always be offered, at least with a factor 1. If the\r
- TCP sliding window size becomes more than 64KB, the factor will increase\r
- automatically.\r
- + ipconfigETHERNET_MINIMUM_PACKET_BYTES is now applied for every protocol:\r
- TCP, UDP, and ARP.\r
- + Updated the Zynq project to use BufferAllocation_1.c rather than\r
- BufferAllocation_2.c - which is a requirement with its current\r
- configuration (due to the alignment requirements on the combined cache and\r
- DMA configuration).\r
-\r
-Changes between 160823 and 160908 releases:\r
-\r
- + Use ipconfigZERO_COPY_TX_DRIVER as the xReleaseAfterSend() parameter where\r
- prvTCPReturnPacket() is called in prvSendData() to prevent unnecessary\r
- copying of data.\r
- + Remove the use of the uxGetRxEventCount variable, which was used to give\r
- priority to incoming messages, but could result in the IP task starving\r
- application tasks of processing time.\r
-\r
-Changes between 160112 and 160823 releases\r
-\r
- NOTE: The 160908 release is a maintenance release for the 160112 single\r
- interface labs release - not a release of the current development branch.\r
-\r
- + Various minor stability enhancements, including the ability to work with\r
- configTICK_RATE_HZ set to less than 1KHz, closing DHCP sockets directly\r
- rather than via FreeRTOS_closesocket(), and better handling of unknown\r
- TCP packets before an IP address has been assigned.\r
- + ipBUFFER_PADDING is now configurable through the ipconfigBUFFER_PADDING\r
- constant to improve network buffer alignment handling capabilities (expert\r
- users/driver writers only).\r
- + Multiple improvements to the FTP server, including to how read only and\r
- zero length files are handled.\r
- + ipconfigFTP_HAS_USER_PROPERTIES_HOOK (to allow each user to have a\r
- different root directory and access rights) and\r
- ipconfigHTTP_HAS_HANDLE_REQUEST_HOOK (to handle AJAX style data)\r
- introduced, although these are not yet fully tested and the constant names\r
- are likely to change.\r
- + Introduce ipconfigHAS_TX_CRC_OFFLOADING.\r
- + ipconfigUSE_DHCP_HOOK is now called ipconfigUSE_DHCP_HOOK, and the name\r
- of the callback function has also changed. See the web documentation for\r
- details.\r
- + ipconfigTCP_RX_BUF_LEN is now ipconfigTCP_RX_BUFFER_LENGTH, and\r
- ipconfigTCP_TX_BUF_LEN is now ipconfigTCP_TX_BUFFER_LENGTH, which is\r
- actually how they have always been documented.\r
- + Added example TFTP server capable of receiving (not sending) files.\r
- Intended for bootloader type functionality.\r
- + Various variable name changes for consistency (mainly ensuring UDP, TCP,\r
- DNS, etc. always use the same case letters, and type prefixes are correct).\r
- + Various minor edits to improve types used by internal variables.\r
- + Simplified mapping of standard library functions to their Visual Studio\r
- equivalents.\r
- + Improve robustness of network drivers.\r
- + Introduce pxResizeNetworkBufferWithDescriptor().\r
- + Removed obsolete FreeRTOSIPConfig.h constants from\r
- FreeRTOSIPConfigDefaults.h.\r
- + Added additional asserts() - predominantly to catch incorrect structure\r
- packing.\r
-\r
-Changes between 160112 and 160111 releases\r
-\r
- + Updated the STM32 network driver so checksums are calculated by the\r
- hardware.\r
- + Implemented a simple "quit" command in the TCP command console.\r
-\r
-Changes between 150825 and 160111 releases\r
-\r
- + New device support: Demo applications and example drivers are provided\r
- for Atmel SAM4E and ST STM32F4 microcontrollers.\r
- + Various updates to improve compliance with the FreeRTOS coding standard.\r
- + Added a command console example that uses TCP/IP for input and output (the\r
- pre-existing command console example uses UDP/IP).\r
- + Updated the UDP logging example so it will send log messages to the local\r
- UDP broadcast address if a specific IP address is not provided. This\r
- simplifies configuration, but note not all switches and routers will pass\r
- broadcast messages.\r
- + Add TCP echo client and TCP echo server examples to the Zynq demo.\r
- + Minor updates to the Zynq network driver.\r
- + Update the Zynq project to use version 2015.4 of the Xilinx SDK.\r
- + Introduce FreeRTOS_SignalSocket(), which can be used to interrupt a task\r
- that is blocked while reading from a socket ( FreeRTOS_recv[from] ).\r
- + Make use of FreeRTOS_SignalSocket() in the FTP and HTTP servers.\r
- + Major updates to the NTP client, although this is not included in any of\r
- the pre-configured demo applications yet.\r
- + Added support for DHCP zero pad option.\r
- + Added uxGetMinimumIPQueueSpace(), a function to monitor the minimum amount\r
- of space on the message queue.\r
- + Better handling of zero length files in the FTP server.\r
- + Fixed a bug reported by Andrey Ivanov from swissEmbedded that affects\r
- users of 'ipconfigZERO_COPY_TX_DRIVER'.\r
-\r
-\r
-Changes between 150825 150825 (?)\r
-\r
- + Added xApplicationDHCPUserHook() so a user defined hook will be\r
- called at certain points in the DHCP process if\r
- ipconfigDHCP_USES_USER_HOOK is set to 1.\r
- + Added FreeRTOS_get_tx_head() to improve TCP zero copy behaviour - for\r
- expert use only.\r
- + RST is no longer sent if only the ACK flag is set.\r
- + Previously, an immediate ACK was only sent when buffer space was\r
- exhausted. Now, to improve performance, it is possible to send an\r
- immediate ACK earlier - dependent on the ipconfigTCP_ACK_EARLIER_PACKET\r
- setting.\r
- + LLMNR and NBNS requests can now be sent to locate other devices -\r
- previously these protocols would only be replied to, not generated.\r
- + Added Auto-IP functionality (still in test) in case DHCP fails. Dependent\r
- on the ipconfigDHCP_FALL_BACK_LINK_LAYER_ADDRESS and\r
- ipconfigARP_USE_CLASH_DETECTION settings.\r
- + Added NTP code and demo.\r
- + FTP can now STOR and RETR zero-length files.\r
- + Added LLMNR demo to Win32 demo - so now the Win32 responds to\r
- "ping RTOSDemo".\r
-\r
-Changes between 141019 and 150825\r
-\r
- + Added FTP server, which uses the new FreeRTOS+FAT component.\r
- + Added basic HTTP server, which uses the new FreeRTOS+FAT component.\r
- + Multiple definitions that are now common with FreeRTOS+FAT have been moved\r
- into FreeRTOS's ProjDefs.h header file, and so prefixed with 'pd'.\r
- + Introduced ipconfigZERO_COPY_TX_DRIVER, which defines who is responsible\r
- for freeing a buffer sent to to the MAC driver for transmission, and\r
- facilitates the development of zero copy drivers.\r
- + Introduced the FREERTOS_MSG_DONTWAIT flag. The flag can be used as a\r
- simpler and faster alternative to using FreeRTOS_setsockopt() to set the\r
- send or receive timeout to 0.\r
- + A few functions that were previously all lower case are now mixed case, as\r
- lower case function names are only used when they are equivalent to a\r
- a Berkeley sockets API function of the same name.\r
- + Introduced uxGetMinimumFreeNetworkBuffers() to return the minimum number\r
- of network buffers that have ever existed since the application started\r
- executing.\r
- + Introduce ipconfigETHERNET_MINIMUM_PACKET_BYTES to allow the application\r
- writer to set their own minimum buffer size should the hardware not be\r
- capable of padding under-sized Ethernet frames.\r
- + vNetworkBufferRelease() renamed vReleaseNetworkBuffer() - just for\r
- consistency with the names of other functions in the same file.\r
- + Grouped DHCP status data into a structure.\r
- + DHCP is now tried both with and without the broadcast flag.\r
- + Replaced occurrences of configASSERT_VOID() with configASSERT().\r
- + ipconfigDNS_USE_CALLBACKS introduced to allow FreeRTOS_gethostbyname() to\r
- be used without blocking.\r
- + Fix: LLMNR and NBNS behaviour when the reply is in a larger buffer than the\r
- request, and BufferAllocation_2 was used.\r
- + Introduced ipMAX_IP_TASK_SLEEP_TIME to allow the application writer to\r
- override the default value of 10 seconds.\r
- + Fix: Correct error in *pxUDPPayloadBuffer_to_NetworkBuffer().\r
- + FreeRTOS_recv() now recognises the FREERTOS_ZERO_COPY flag, which, when\r
- set, the void *pvBuffer parameter is interpreted as void **pvBuffer.\r
- + FreeRTOS_listen() now returns an error code. Previously it always\r
- returned 0.\r
- + Fix: Previously if a listening socket was reused, and a connection\r
- failed, the TCP/IP stack closed the socket, now the socket is correctly\r
- left unclosed as it is owned by the application.\r
- + Various other formatting and minor fix alterations.\r
