The use of integer types from inttypes.h & stdint.h should help with
portability issues. It will also force the data transmission between
different architectures to work as intended (if we handle endianess
conversions correctly!).
Abandon the old struct timeval and gettimeofday(). We now use the new
struct timespec and clock_gettime().
struct timespec has a nanosecond resolution, but we lower the resolution
to keep only milliseconds. The code is inspired from the Timestamp class
of the owlps-positioning.
The type TIMESTAMP is a wrapper to the currently-used time structure (we
currently use struct timeval).
The function timeval_to_ms() is now timestamp_to_ms().
The listener does not send its IP address explicitly in the Hello
message anymore. Instead, the aggregator now extract the source address
of the Hello packet.
The packet captured are no longer displayed when in verbose mode.
The new option 'display_captured' (or command-line -c) activates this
behaviour. One can use -Q to deactivate.
Autocalibration positioning requests were previously (and stupidly) sent
on the aggregation port. We can now chose the port for autocalibration
requests.
The new option -V displays the compilation-time options. In the future,
it should display the version number.
When the user calls the program either with -h or the new option -V, we
do not try any more to open and parse the configuration file (which was
useless since -h, and now -V, exit the program).
Makefile_atheros:
- Add target 'static' to compile fully statically. (Note: does not
work in the OpenWRT 8.09 cross-compilation suite, since it does not
provide libiw.a)
- Add target 'semistatic', that compiles with static libowlps and
dynamic libiw and libpcap.
Fix (mostly) endianess issues:
- le32toh() is defined only in glibc >= 2.9, so owlps-listener did not
compile with older glibc or other libc (such as uClibc that we use to
cross-compile to OpenWRT).
We now define le32toh() manually, if needed.
- Additionally, the PLATFORM_ATHEROS define is removed. We should now
test the value of __BYTE_ORDER if needed.
listener + libowlps : nettoyage, amélioration de la qualité du code,
tests sur le type du paquet capturé.
