59643679f8 libc/stdlib: Error Fix 
1.Fix an error in mkstemp() the could result in an infinite loop.
2.Fix for wrong output in some cases.
For Example:
 1) input: "FILEXX"
    output: "FILE00" and repeats same output for further invocations of mkstemp().
            But, the ouput has to be FILE01, FILE02, ...., FILEZZ.
 2)input: "FILEXXXXXX"
   output: "FILE100000", for next invocation "FILE200000" and so on
           But it's good, if the ouput goes like FILE000001, FILE000002, ..., FILE000101, ...

beec197c69 libc/math: Fix wrong ouput in ceil() API 
Ex:for input x = 1.0, the ouput should be 1.0, but the ouput was 2.0.

6062af0a94 libc/math: Fix wrong ouput in modf() API 
The sign of integral part given by the modf() should be same as sign of input.
But for inputs between 0 and 1, the sign of integral part was not same as sign of input.

4504ca7c82 Whoops -- that #include <cxxabi.h> wasn't supposed to sneak in there. If present, it may already define a __cxxabiv1::__guard that we could use, but that file comes from libstdc++, and I don't think the NuttX buildroot-based toolchain would have that, which is why we need libxx in the first place. 2017-06-09 07:40:31 -06:00

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
