arc4random_buf() segfaults on MIPS32 with uClibc-0.9.33.2. about openbsd HOT 3 CLOSED

Unfortunately we'll need more than this to investigate/resolve - can you please provide sample code and a back trace?

@4a6f656c Yeah, it might be due to a buggy pthreads implementation or whatever; however porting the arc4random_buf() function to uClibc resolves this problem.

I guess other people might find this useful.

in libc/stdlib/arc4random.c I've added this:

void arc4random_buf(void *buf_, size_t n)
{
	unsigned char *buf = buf_;
	if (!rs_initialized)
		__arc4random_stir();
	while (n--) {
		buf[n] = arc4_getbyte(&rs);
	}
}

@nihilus - thanks, if we can get a trace we might be able to isolate the problem, without that there's not much we can do. Since you have a workaround, I'll close this - please reopen if further information can be provided.
