litmus-rt.git/drivers/char/xillybus, branch master The LITMUS^RT kernel. char: xillybus: Don't return -EFAULT on user-triggered flush 2015-04-03T14:15:30+00:00 Eli Billauer eli.billauer@gmail.com 2015-03-27T08:56:06+00:00 127af8828518074ab24e9b5678229513d198d832 The API allows the application to flush a host-to-FPGA stream by calling write() with the data count set to zero. Before this patch, copy_from_user() was called with a non-zero byte count, which possibly made it attempt to read from unmapped user memory. Such attempts caused the driver to return -EFAULT instead of 0, even though the desired operation went through fine. This patch ensures the driver returns 0 on a successful flush.

The API allows the application to flush a host-to-FPGA stream by calling
write() with the data count set to zero. Before this patch, copy_from_user()
was called with a non-zero byte count, which possibly made it attempt to read
from unmapped user memory. Such attempts caused the driver to return -EFAULT
instead of 0, even though the desired operation went through fine.

This patch ensures the driver returns 0 on a successful flush.
