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"

|
|
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. |
