6309165fe0 tools/nxstyle.c: Add automatic detection of line width based on examining
the width of all block comments. Includes a check to assure that all block
comments use the same line width.

Verified against all .c files under /sched.  There were a few cosmetic changes to the coding style under /sched to account to new, correctly detected problems in the /sched files.

2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

a12f80fb90 sched/mqueue/mq_desclose.c: Add a test to verify that message queue is closed by the same task group that opened it. If not, then list corruption would result. This test is only performed if CONFIG_DEBUG_FEATURES is enabled since it should not normally be an issue: It would be a strange programming practice to open a message queue in open task group, then close it in another. 2019-08-05 18:30:07 -06:00

fc127fd297 sched/signal: Add a generic signal notification facility. Modify the custom IOB available notifier so that it is now just a wrapper around this generic signal notification. This generic signal notification faility will, eventually, be used to support network polling.
Squashed commit of the following:

    mm/iob:  The IOB available notifier is now just a wrapper around the common signal notifier.

    sched/signal:  Add a generic signal notification facility.

    sched/signal/sig_evthread.c:  More trivial naming changes.

    sched/signal:  Rename nxsig_notification() to nxsig_evthread() to make forthcoming naming additions more consistent.

sched/mqueue/mq_notify.c: Fix - only part of struct copied to internal structure

As source adress the adress of the struct member sigev_value was used,
and it is not located the start of the struct.
This leads to invalid data being copied to internal structure.
Both source and destination should be of type struct sigevent* .

e11e3b2607 Squashed commit of the following:
Change all calls to mq_receive() and mq_timedreceive() in the OS to calls to nxmq_receive() and nxmq_timedreceive(), making appropriate changes for differences in return values.

    sched/mqueue:  Add nxmq_receive() and mxmq_timedreceive() which are functionally equivalent to the standard mq_receive and mq_timedreceive() except that (1) they do not create cancellation points, and (2) the do not modify the application's errno variable.

8198ba6a6d This change renames all internal, private NuttX signal-related functions to use the prefix nxsig_ so that they cannot be confused with application interfaces that begin, primarily, with sig_
This is analogous to similar renaming that was done previously for semaphores.

Squashed commit of the following:

    sched/signal:  Fix a few compile warnings introduced by naming changes.

    sched/signal:  Rename all private, internal signl functions to use the nxsig_ prefix.

    sched/signal:  Rename sig_removependingsignal, sig_unmaskpendingsignal, and sig_mqnotempty to nxsig_remove_pendingsignal, nxsig_unmask_pendingsignal, and nxsig_mqnotempty to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_findaction and sig_lowest to nxsig_find_action and nxsig_lowest to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_allocatepingsigaction and sig_deliver to nxsig_alloc_pendingsigaction and nxsig_deliver to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_cleanup, sig_release, sig_releasependingaction, and sig_releasependingsignal to nxsig_cleanup, nxsig_release, nxsig_release_pendingaction, and nxsig_release_pendingsignal to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_tcbdispatch and sig_dispatch to nxsig_tcbdispatch and nxsig_dispatch to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_releaseaction and sig_pendingset to nxsig_release_action and nxsig_pendingset to make it clear that these are OS internal interfaces.

    sched/signal:  Rename sig_initialize and sig_allocateactionblock to nxsig_initialize and nxsig_alloc_actionblock to make it clear that these are OS internal interfaces.

dca77fa06a sigtimedwait: When timer expires, up_unblock_task() is called. This is okay in the single CPU case because interrupts are disable in the timer interrupt handler.
