Update to V2.0.7 of the TCP/IP stack:
+ 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.
+ Support tickless idle when configUSE_PREEMPTION is 0 (previously tickless idle was only supported when the pre-emptive scheduler was being used).
+ If a stack was statically allocated, then don't try freeing it if the TCB cannot be allocated.
+ Remove use of INCLUDE_xEventGroupsSetBitsFromISR() pre-processor macro, as it was not tested anyway.
Demo app changes:
+ Updated SAM4L Atmel Studio project to use Atmel Studio 7.
Windows port: Add code to ensure Windows threads are truely suspended before resuming another thread.
Typo correction to the task notification standard demo task.
Correct case of some include file names to fix build issues on Linux.
Allow the stats formatting functions to be built in without stdio.h being included inside tasks.c.
Kernel port code:
- Slight change to the Cortex-A GIC-less port to move all non portable code to the application level.
SAMA5D4 demo project:
- Update the Atmel provided library to V1.1.
- Create a DDR build configuration.
- Ensure interrupts are all edge sensitive.
- Update the regtest code to use all 32 flop registers.
+ Change how queues are allocated and deleted so only one pvPortMalloc() or vPortFree() is required in place of the previous 2.
+ Where the TCB is allocated in relation to the stack is now dependent on the stack growth direction. The stack will not grow into the TCB.
+ Introduce the configAPPLICATION_ALLOCATED_HEAP constant to allow the application to provide the array used by heap_4.c as its heap. This allows the application writer to use qualifiers on the array to, for example, force the memory into faster RAM.
Demo application:
+ Add demo for SAMA5D4 using IAR.
