1 Changes since the 160112 release
\r
3 FTP : now has ipconfigFTP_HAS_USER_PROPERTIES_HOOK
\r
4 Each user can be assigned a different root directory and different access rights.
\r
5 Read-only access for FTP is now possible.
\r
7 Adapted to comply a bit more to MISRA rules.
\r
8 The introduction of unsigned true/false, e.g. pdTRUE_UNSIGNED.
\r
10 'ipBUFFER_PADDING' now configurable (expert option).
\r
12 Added ipconfigFTP_HAS_USER_PROPERTIES_HOOK.
\r
13 ipconfigHAS_TX_CRC_OFFLOADING
\r
14 Improve support for read only file systems in the FTP server.
\r
16 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.
\r
18 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.
\r
20 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.
\r
22 "#if __cplusplus" is been replaced with the more proper test "#ifdef __cplusplus".
\r
26 These are the recent commits:
\r
27 565 Initial check-in of +TCP/multi
\r
28 566 LPC18xx : updated and re-tested the TCP and FAT drivers
\r
29 569 +TCP : protocols: Added an installable application hook: "CheckDrivesHook"
\r
30 570 +TCP : will now work properly when configTICK_RATE_HZ < 1000
\r
31 571 +TCP : will now work properly when configTICK_RATE_HZ < 1000
\r
32 572 +TCP : FreeRTOS_recvfrom now recognises "FREERTOS_MSG_PEEK"
\r
33 573 +FAT : Zynq : writing may fail if it goes too fast. Introduced pauses but not yet satisfied
\r
36 Changes between 160112 and 160111 releases
\r
38 + Updated the STM32 network driver so checksums are calculated by the
\r
40 + Implemented a simple "quit" command in the TCP command console.
\r
42 Changes between 150825 and 160111 releases
\r
44 + New device support: Demo applications and example drivers are provided
\r
45 for Atmel SAM4E and ST STM32F4 microcontrollers.
\r
46 + Various updates to improve compliance with the FreeRTOS coding standard.
\r
47 + Added a command console example that uses TCP/IP for input and output (the
\r
48 pre-existing command console example uses UDP/IP).
\r
49 + Updated the UDP logging example so it will send log messages to the local
\r
50 UDP broadcast address if a specific IP address is not provided. This
\r
51 simplifies configuration, but note not all switches and routers will pass
\r
53 + Add TCP echo client and TCP echo server examples to the Zynq demo.
\r
54 + Minor updates to the Zynq network driver.
\r
55 + Update the Zynq project to use version 2015.4 of the Xilinx SDK.
\r
56 + Introduce FreeRTOS_SignalSocket(), which can be used to interrupt a task
\r
57 that is blocked while reading from a socket ( FreeRTOS_recv[from] ).
\r
58 + Make use of FreeRTOS_SignalSocket() in the FTP and HTTP servers.
\r
59 + Major updates to the NTP client, although this is not included in any of
\r
60 the pre-configured demo applications yet.
\r
61 + Added support for DHCP zero pad option.
\r
62 + Added uxGetMinimumIPQueueSpace(), a function to monitor the minimum amount
\r
63 of space on the message queue.
\r
64 + Better handling of zero length files in the FTP server.
\r
65 + Fixed a bug reported by Andrey Ivanov from swissEmbedded that affects
\r
66 users of 'ipconfigZERO_COPY_TX_DRIVER'.
\r
69 Changes between 150825 150825 (?)
\r
71 + Added xApplicationDHCPUserHook() so a user defined hook will be
\r
72 called at certain points in the DHCP process if
\r
73 ipconfigDHCP_USES_USER_HOOK is set to 1.
\r
74 + Added FreeRTOS_get_tx_head() to improve TCP zero copy behaviour - for
\r
76 + RST is no longer sent if only the ACK flag is set.
\r
77 + Previously, an immediate ACK was only sent when buffer space was
\r
78 exhausted. Now, to improve performance, it is possible to send an
\r
79 immediate ACK earlier - dependent on the ipconfigTCP_ACK_EARLIER_PACKET
\r
81 + LLMNR and NBNS requests can now be sent to locate other devices -
\r
82 previously these protocols would only be replied to, not generated.
\r
83 + Added Auto-IP functionality (still in test) in case DHCP fails. Dependent
\r
84 on the ipconfigDHCP_FALL_BACK_LINK_LAYER_ADDRESS and
\r
85 ipconfigARP_USE_CLASH_DETECTION settings.
\r
86 + Added NTP code and demo.
\r
87 + FTP can now STOR and RETR zero-length files.
\r
88 + Added LLMNR demo to Win32 demo - so now the Win32 responds to
\r
91 Changes between 141019 and 150825
\r
93 + Added FTP server, which uses the new FreeRTOS+FAT component.
\r
94 + Added basic HTTP server, which uses the new FreeRTOS+FAT component.
\r
95 + Multiple definitions that are now common with FreeRTOS+FAT have been moved
\r
96 into FreeRTOS's ProjDefs.h header file, and so prefixed with 'pd'.
\r
97 + Introduced ipconfigZERO_COPY_TX_DRIVER, which defines who is responsible
\r
98 for freeing a buffer sent to to the MAC driver for transmission, and
\r
99 facilitates the development of zero copy drivers.
\r
100 + Introduced the FREERTOS_MSG_DONTWAIT flag. The flag can be used as a
\r
101 simpler and faster alternative to using FreeRTOS_setsockopt() to set the
\r
102 send or receive timeout to 0.
\r
103 + A few functions that were previously all lower case are now mixed case, as
\r
104 lower case function names are only used when they are equivalent to a
\r
105 a Berkeley sockets API function of the same name.
\r
106 + Introduced uxGetMinimumFreeNetworkBuffers() to return the minimum number
\r
107 of network buffers that have ever existed since the application started
\r
109 + Introduce ipconfigETHERNET_MINIMUM_PACKET_BYTES to allow the application
\r
110 writer to set their own minimum buffer size should the hardware not be
\r
111 capable of padding under-sized Ethernet frames.
\r
112 + vNetworkBufferRelease() renamed vReleaseNetworkBuffer() - just for
\r
113 consistency with the names of other functions in the same file.
\r
114 + Grouped DHCP status data into a structure.
\r
115 + DHCP is now tried both with and without the broadcast flag.
\r
116 + Replaced occurrences of configASSERT_VOID() with configASSERT().
\r
117 + ipconfigDNS_USE_CALLBACKS introduced to allow FreeRTOS_gethostbyname() to
\r
118 be used without blocking.
\r
119 + Fix: LLMNR and NBNS behaviour when the reply is in a larger buffer than the
\r
120 request, and BufferAllocation_2 was used.
\r
121 + Introduced ipMAX_IP_TASK_SLEEP_TIME to allow the application writer to
\r
122 override the default value of 10 seconds.
\r
123 + Fix: Correct error in *pxUDPPayloadBuffer_to_NetworkBuffer().
\r
124 + FreeRTOS_recv() now recognises the FREERTOS_ZERO_COPY flag, which, when
\r
125 set, the void *pvBuffer parameter is interpreted as void **pvBuffer.
\r
126 + FreeRTOS_listen() now returns an error code. Previously it always
\r
128 + Fix: Previously if a listening socket was reused, and a connection
\r
129 failed, the TCP/IP stack closed the socket, now the socket is correctly
\r
130 left unclosed as it is owned by the application.
\r
131 + Various other formatting and minor fix alterations.
