The delay parameter has 'int' type while explicit int32_t is used in sigtimedwait() (sig_timedwait.c) This can lead to wrong argument for systems that have default int size different than int32 (namely AVR).

Logic for delayed memory garbage collection for the case of user space memory will not work as implemented for the case of the kernel build. That is because the correct context is in place in order to free the user memory when sched_kufree is called, but will not be in place later when the memory garbage collection runs. If this feature is really needed, then some more substantial redesign is required

Networking: Divide net_intiialize() into net_setup() and net_initialize() to solve a chicken-and-egg problem. net_setup() must be caleld before up_initialize() is called so that networking data structures are ready to register new network devices.
...
net_initialize() now does only timer related operations and is called AFTER up_initialize() where the timers are configured. This is really.

Fix a problem in clock_systimer64 that occurs when (1) the 64-bit system time is enabled, and (2) the value of CONFIG_USEC_PER_TICK is less than 1 millisconds (such as when using the tickless mode of operation). In that case, the convertion of time to 64-bit millisecond value in clock_systmer64() causes some bad times to be returned. Time was converted to milliseconds, then to configured ticks. Precision was lost in the millisecond convertion.
...
The fix is to first convert time to a 64-bit microsecond value, then to the configured tick value.

gettimeofday() and settimeofday(): Move gittimeofdady() from sched/clock to libc/time. All remove gettimeofday() from NuttX system calls. It is only a wrapper around clock_settime() and does not need a trap. gettimeofday() is no longer tried as a core OS interface.
...
gettimeofday has been decremented in POSIX 2008. settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry.

Semaphores: sem_waitirq.c must be built when signals are disabled. That is because not handles not only the case of semaphore wait being awakened by a signal, but also the case with sem_timedwait.c when the semaphore wait is awakened by a timeout.

strncpy will not copy the terminating \0 into the destination if the source is larger than the size of the destination. Ensure that the last byte is always zero and let strncpy only copy CONFIG_TASK_NAME_SIZE bytes.

alling mq_timedreceived with immediate timeout was getting stuck and not
...
timeout. Immediate timeout is achieved by setting absolute timeout value to
past time, for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute
time was converted to relative time using unsigned integer arithmetic and
resulted large ticks count by clock_abstime2ticks, instead of expected negative
ticks value.
Patch corrects clock_abstime2ticks to return negative ticks, if absolute time
is in the past.
