Security Issues Fixed In This Release

Compatibility Concerns

#10605 Implement ticket spinlock

A proposal to slove #1488

Implement ticket spinlock.

#10861 spinlock: Add spin_lock_init and spin_is_locked macro

align with Linux api naming.

#11102 sched: explicitly select the cpuload clock source configuration

Different configurations require different dependencies. Explicitly select dependencies to avoid automatically selecting inappropriate configurations.

#11334 stm32h7_adc: Dynamically set clock prescaler and BOOST

First commit is aligning naming and is a breaking change.

#10827 Improve adjtime() functionality

Prior pull request #9084 and issue #8858 added basic adjtime() support for the SAMv7 platform.

This pull request adds support for STM32 platform.

In addition I have made a few changes to the adjtime() configuration options:

Previously adjustments less than 1 microsecond per tick would be completely ignored. Now they are applied over a shorter period at a rate of 1 us per tick.
Previously CLOCK_ADJTIME_PERIOD was in units of 1/100th of second. Change to milliseconds to be more generally useful unit. Change setting name to CLOCK_ADJTIME_PERIOD_MS to make the unit change easier to notice.
Previously CLOCK_ADJTIME_SLEWLIMIT was in percentage. Most clock crystals have better accuracy than 1%, so the minimum slew rate was excessive. Change to CLOCK_ADJTIME_SLEWLIMIT_PPM with setting value in parts per million.
No need to use floating point math in clock_adjtime.c.

Impact

Users who have used CLOCK_ADJTIME_PERIOD and CLOCK_ADJTIME_SLEWLIMIT settings should update their configuration. New CLOCK_ADJTIME_PERIOD_MS is 10x the old period value, and new CLOCK_ADJTIME_SLEWLIMIT_PPM is 10000 times the old slewlimit.

How to Clone the Git Repository

The Apache NuttX project uses Git SCM as its version control system.

There are two primary repositories:

nuttx - The real time operating system itself.
apps - Optional applications and example programs for the operating system. You can use this repository or make your own custom one.

The main "Single Source of Truth" repositories are hosted by the ASF:

These are synchronized with repositories hosted at GitHub:
