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.

360539afac Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is only a single, hard-allocated holder structure. This is problem because in sem_wait() the holder is released, but needs to remain in the holder container until sem_restorebaseprio() is called. The call to sem_restorebaseprio() must be one of the last things the sem_wait() does because it can cause the task to be suspended. If in sem_wait(), a new task gets the semaphore count then it will fail to allocate the holder and will not participate in priority inheritance. This fix is to add two hard-allocated holders in the sem_t structure: One of the old holder and one for the new holder. 2017-03-10 09:30:15 -06:00

c83da3c48f Remove minnsh configurations and support logic: up_getc() and lowinstream. 
This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful:  (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU.  NOt a reasonably solution other than as a proof of concept.

57ad019fba Revert "Correct a problem in clock_gettime(CLOCK_REALTIME, &time); which is ahead by 1 month of the specified CONFIG_START_MONTH" 
I don't believe this change is correct in general.  Nomralling clock_isleapyear() is called with tm_mon which is in the range of 0-11.  That change would be bad for that range.  It would make sense for a range of 1-12, but that is not how tm_mon is defined.

This reverts commit 1796a25e53.

b1ed7910f0 Allows c++ code to compile with or without CONFIG_LIBC_LOCALE 
and will generate a link error if CONFIG_LIBC_LOCALE is not defined
and setlocale is referneced. With CONFIG_LIBC_LOCALE defined
setlocale will act as if MB string is not supported and return
"C" for POSIX. C and ""

a626ba5b70 libc/time: This commit adds the difftime() function. Since the function returns a double, I have isolated it in a CONFIG_LIBC_DIFFTIME option (It also depends on the toolchain-dependent CONFIG_HAVE_DOUBLE so is not available on tiny platforms). 2016-08-24 15:43:57 -06:00
