e0b4a10dfa drivers/serial/pty.c, serial.c, usbdev/cdcacm.c, include/nuttx/fs/ioctl.h: Fix FIONWRITE and add FIONSPACE. All implementations of FIONWRITE were wrong. FIONWRITE should return the number of bytes waiting in the outgoing send queue, not the free space. Rather, FIONSPACE should return the free space in the send queue. 2016-07-25 14:06:32 -06:00

4f83d58b24 USBMSC: Fix reversed logic on waiting for SCSI thread start.
The scsi thread was waiting for the wrong condition.

However, this was masked by the fact that the code creating the scsi thread
was also holding usbmsc_scsi_lock(priv) while initializing data, hence this
lock synchronized the scsi thread start with init completion.

9a8c3572db serial.c: Fix a race condition noted by Stefan Kolb. Between the test if the TX buffer is full and entering a critical section, bytes may be removed from the TX buffer making the wait unnecessary. The unnecessary wait is an inefficiency, but not really a problem. But with USB CDC/ACM it can be a problem because the entire TX buffer may be emptied when we lose the race. If that happens that uart_putxmitchar() can hang waiting for data to be removed from an empty TX buffer. 2016-07-22 07:47:59 -06:00

6cefbc0c3f This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write. 2016-07-17 06:42:26 -06:00
