d452a05910 pollnotify: we should send poll events before semaphore incrementes.
There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

5498f72fa5 input: Q10 BlackBerry Keyboard from Solder Party
This adds support for the Q10 BlackBerry based keyboard
from Solder Party. https://www.solder.party/docs/keyboard-pmod/

They keyboard device registered at /dev/kbdN is fully compatible
with hidkbd and has been testing with the Keyboard FeatherWing
on the nRF52 platform.

The buttons are added as a standard discrete joystick if
optionally enabled.  The PMOD variant of this does not
include these buttons, but the Keyboard FeatherWing does.
This joystick is usually defined at /dev/djoyN and
can be used with the djoy example application.

7554eedf9a input: STMPE811 GPIO interrupt bug fixes
This patch resolves to bugs in the GPIO interrupt logic:

1. Any pins did not have STMPE811_GPIO_RISING in their pincfg
   would clear the rising edge interrupt enable flag for all
   pins due to a masking bug.

2. Pins would never trigger a second interrupt.  There is an
   undocumented requirement that you have to clear both the
   GPIO interrupt status register __and__ also the edge
   detection status register.  Failure to clear either of
   these will result in no further interrupts being triggered.
   This requirement exists both for edge and level modes of
   operation.

5c0e8e88b1 Revert "Makefile: move INCDIROPT to common place (#625)"
This reverts commit b9ace36fcc.

This change was added by PR 625 but has a serious logic flaw.  It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:

    else ifeq ($(WINTOOL),y)
      DEFINE = "$(TOPDIR)/tools/define.sh"
      INCDIR = "$(TOPDIR)/tools/incdir.sh" -w

This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined.  As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.

21aef0dd68 drivers/*/Kconfig: Consolidate driver Kconfig Files.
This commit does two things:

1. First, it reorganizes the driver Kconfig files so that each is self contained.  Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig.  Now, all of the driver configuration is consolitated in the latter.

2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files.  This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well.

The nature of the introduced error was basically this:

- Nothing must intervene between the menuconfig selection and the following conditional configuration otpions.
- A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus.

This error was easy to make because the driver Kconfig files were not well modularized.  Making them fully self-contained should eliminate this kind of error in the future.

No... I was misled.  The shutdown function is usually called when the
driver is unlinked.  But not in this case.  In this case, it is simply
called when the last reference is closed.  And no, you don't want to
detach the interrupt handler in that case.  My bad.

61372551e9 Merged in hardlulz/modem-3.0-nuttx/fix-stmpe811-gpio (pull request #523)
Fix GPIO operation of STMPE811 driver.

Fixed issues:
1. STMPE811_GPIO_DIR was defined for register name
   and later was redefined to be the pin direction mask
   for `stmpe811_gpioconfig`

   I decided to change register name to be STMPE811_GPIO_DIR_REG,
   and keep pin direction mask STMPE811_GPIO_DIR, so that any
   external code that already use this driver will be unchanged.

2. The STMPE811 register GPIO_DIR uses bit value 1 for output
   and 0 for input, but `stmpe811_gpioconfig` set the opposite.

3. The call to `stmpe811_gpiowrite` from inside of `stmpe811_gpioconfig`
   leaded to deadlock.

Replace all calls to sigqueue() in the OS proper with calls to nxsig_queue() to avoid accessing the errno variable.

    sched/signal:  Add nxsig_queue() which is functionally equivalent to sigqueue() except that it does not modify the errno variable.

936df1bcb5 Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().

7fc7cc9f8f drivers/input/cypress_mbr3108: Add missing variable for nxsem_wait return value 2017-10-06 07:30:04 -06:00
Gregory Nutt
9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.

dffb8a67e3 Add entropy pool and strong random number generator
Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output.

Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.
