when it is not in use.

Tobias Girstmair 142325a93c Fix signal handler from getting stuck in an endless loop
The signal handler for SIGINT/TERM/QUIT and, importantly, SIGPIPE tries
to write an informational message to stderr. When however stderr is
redirected to a closed pipe, this will cause (another) SIGPIPE, and in
turn the signal handler will get called again, and again and again.

Since we intend to exit rtl_fm anyways, we can just ignore this signal.

Clayton Smith 5e73f90f1d lib: Stop applying workaround for libusb < 1.0.9
Librtlsdr has a workaround for libusb versions that lack
libusb_handle_events_timeout_completed, which was added in version 1.0.9
(released 2012-04-02). The workaround is always applied unless the
HAVE_LIBUSB_HANDLE_EVENTS_TIMEOUT_COMPLETED macro is set, but the cmake
code that sets this macro was removed in
849f8efca4. As a result, the workaround is
now always applied. This results in an extra 1-second delay whenever a
GNU Radio flowgraph containing an RTL-SDR block is stopped, which makes
operations like switching between demodulators in Gqrx annoyingly slow.

To solve this problem, I've simply removed the workaround, as it should
no longer be needed.

I wonder if perhaps the workaround recently applied in
2659e2df31 might stem from the same bug.

Derrick Pallas d794155ba6 tuner_r82xx: fix short-write in r82xx_read
In r82xx_read, there is a 1-byte I2C write followed by the I2C read.  If
this I2C write fails, r82xx_read correctly bails out but may return 0.
Callers that check whether (rc < 0) will assume that the buffer was written
when it has not been, e.g. in r82xx_set_tv_standard where

	priv->fil_cal_code = data[4] & 0x0f;

consumes a garbage value for data[4].

This change resolves that issue by copying the error path from r82xx_write.

Harald Welte dc92af01bf debian: fix source/format from quilt to native
We certainly don't use quilt, as we build packages using

This is what likely causes build failures on our osmocom nightly
builds stating

gbp:error: Non-native package 'rtl-sdr' has invalid version '0.5.4.32.3d7c'

If the package now is 'native', the errors should be gone.

A. Maitland Bottoms 8985b45e1f rtl_tcp: Add IPv6 support
I've prepared this patch in response to Debian bug #870804
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=870804

It passes the text from the -a and -p options through
getaddrinfo() and uses the first result that has a valid
socket with a successful bind.

While not a complete bind to all possible valid names, it
does appear to address the use case of the bug submitter
without completely changing the program flow.

leonsal b5af355b1d Fixed issues compiling on Windows with MSVC, CMake and NMake (#61)
When trying to build a simple program which uses librtlsdr
as a subproject on Windows, CMake reported several problems
which were solved by:
- Added complete name of libusb in FindLibUSB module.
- Replaced CMAKE_SOURCE_DIR to PROJECT_SOURCE_DIR in src/CMakeLists.txt.
- Replaced header file <afxres.h> in src/rtlsdr.rc.in (only present when windows MFC is
  installed) by <windows.h> which defines the same constants.

Steve Markgraf 81833a1cf6 lib: disable usbfs zero-copy support by default
Although we added a detection mechanism for the presence of the Kernel
bug earlier, reading from the incorrectly mapped memory might cause a
bus error on some ARM systems.

With the overall performance benefit being rather minimal for the
data rates of rtl-sdr, disable zero-copy by default.

Steve Markgraf f68bb2fa77 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.
