NuttX-5.12
|
||
|
|
----------
|
||
|
|
|
||
|
|
This is the 59th release of NuttX. This is a critical bugfix release.
|
||
|
|
|
||
|
|
* Fixed an important error in the signal trampoline logic.
|
||
|
|
Essentially, interrupts are re-enabled while the signal handler
|
||
|
|
executes, but the logic to re-disable the interrupts before
|
||
|
|
returning from the signal handler trampoline was missing. Under
|
||
|
|
certain circumstances, this can cause stack corruption. This
|
||
|
|
was discovered by David Hewson on an ARM9 platform, but since
|
||
|
|
the code has been leveraged, the bug has been propagated from
|
||
|
|
ARM to Cortex-M3, AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 --
|
||
|
|
almost every architecture. The correction has been incorporated
|
||
|
|
for all architectures but only verified on a few.
|
||
|
|
|
||
|
|
Other notable changes in NuttX-5.12:
|
||
|
|
|
||
|
|
* A complete port for the AVR32 (AT32UC3B0256) is incorporated
|
||
|
|
in the source tree. Testing of this port is underway now. This
|
||
|
|
release was made before verifying this port in order to get the
|
||
|
|
important bugfix in place.
|
||
|
|
|
||
|
|
* Other miscellaneous bugfix and enhancements as noted in the
|
||
|
|
ChangeLog.
