8ae5450268 pthreads: Move pthread_yield from sched/pthreads to libc/pthreads. it is a simple wrapper for sched_yield and does not belong within the OS. 2017-06-14 07:31:10 -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.

34e539926a Syscalls: Remove modsym() syscall. There is no reason why appication code could ever use symbolic information from a symbol within a kernel module. The modsym() interface is only meaningful within the kernel. 2017-01-28 11:03:06 -06:00

d8db596b3b POSIX message queues: Move mq_setattr() and mq_getattr() from nuttx/libc/mqueue to nuttx/sched/mqueue. Also add sysyscall support for mq_setattr() and mq_getattr(). This is necessary in protected and kernel builds because in those cases the message queue structure is protect and cannot be accessed directly from user mode code.

b4b40d338a boardctl(): Add a new non-standard OS interface. This is similar to a driver IOCTL call. But this is an IOCTL call directly on the board logic. This function will eventually replace all of the ad hoc OS interfaces that are current used to perform application specific intialiation and application driver test confifuration. It essentially formalizes and institutionalizes these rogue interface in to at least a single crazy call. 2015-03-31 11:25:52 -06:00

147042218b 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.

e31d5125ae Add support for a variadic ioctl() function. The ioctl() interface is a non-standard, Unix interface. NuttX has always used the older, three-parameter version. Most contemporary systems now, however, use a variadic form of the ioctl() function. Added an option to insert a shim layer to adapt the three-parameter ioctl() to use the variadic interface form. Internally, the ioctl handling is the same three-parameter logic. The only real complexity to the shim is in how the system calls must be handled. 2014-11-29 10:53:22 -06:00
