Steve Markgraf 077613efc5 improve exit handling on device removal 2019-08-26 19:26:30 +02:00
Steve Markgraf b8d33bfd82 lib: wait for sample worker thread before freeing buffers 
This fixes a segfault when exiting, as sometimes it occured that
the USB worker thread completed before the sample worker thread,
and the buffers the latter was still accessing had already been
freed.

Steve Markgraf 6c21e9d01f fl2k_file: check read return value before repeating 
In case of a FIFO that has been closed or a 0 byte file this
will otherwise lead to an endless loop.

Steve Markgraf df33203db5 lib: Add workaround for Linux usbfs mmap() bug 
The Linux Kernel has a bug on ARM/ARM64 systems where the USB CMA
memory is incorrectly mapped to userspace, breaking zerocopy.

When the Kernel allocates the memory, it clears it with memset().
If the mapping worked correctly, we should have zeroed out buffers,
if it doesn't, we get random Kernel memory. We now check for this,
and fall back to buffers in userspace if that's the case.

dh-autoreconf is enabled by default since debhelper compatibility level
10 (and the debhelper package Depends on dh-autoreconf since version

Harald Welte 79908e1109 libusb-1.0.22 deprecated libusb_set_debug() with libusb_set_option() 
This avoids the following compiler warnings when using more recent
versions of libusb:

src/libosmo-fl2k.c:384:2: warning: ‘libusb_set_debug’ is deprecated: Use libusb_set_option instead [-Wdeprecated-declarations]
  libusb_set_debug(dev->ctx, 3);
