Either I found and fixed a severe bug in PSOCK_READTO() or I misunderstood something completely. To me PSOCK_READTO() is supposed to return if either the supplied character was read or if the user supplied buffer is exhausted - sor far so good.
However if the latter occurs up to now PSOCK_READTO() was continuing to process characters already read from the network (aka present in the uIP buffer) in order to check if the supplied character was found there and adjust the return value accordingly. But this means that the character processed this way were lost forever for the caller as the next call to PSOCK_READTO() would continue to read past the characters processed this way.
Therefore I removed that character processing altogether. So now if the user supplied buffer is exhausted before the supplied character is found the next call to PSOCK_READTO() starts exactly where previous call left off.

This platform is a basic waveshare stm32f107 devkit which contains a
USART, USB device port, some buttons and some LEDs. Unfortunately not
enough to bring up networking, but enough to test building and a
simple contiki shell
This currently supports the stm32f107, but support will be added for
the F105 shortly (missing a linker script and I can't properly test
without a devkit).
While it may very well be beneficial to have explict uiplib_ip4addrconv() and uiplib_ip6addrconv() available for IPv6 builds I'm having a hard time to see the point in uiplib_ip6addrconv() for IPv4 builds.
Unrelated to the above the dispatching of uiplib_ipaddrconv() to either uiplib_ip4addrconv() or uiplib_ip6addrconv() can be accomplished by the C preprocessor only thus avoiding the size/speed overhead of an additional callframe.
This is a major change to how the main tick interrupt is handled on
the mc1322x platforms. Instead of using two timer resources, TMR0 and
RTC, this patch unifies all the timers to use the RTC. This is enabled by
implementing etimers as scheduled rtimers. The main advantage (aside
from freeing TMR0 for general use) is have the Contiki timebase come
from the same source that will be used for sleeping and wakeup.
Better match user expectations by allowing to download plain disk images and configure the IP settings afterwards on the target machine - then most likely leveraging DHCP. This works for the users with the most usual Ethernet adapter and settings - which are now pre-configured in default.cfg's. Only the few users with non-default Ethernet adapter and/or settings are required to download a custom contiki.cfg and inject it manually into their disk image files.
This patch enables automatic route setup and cleanup when
starting and stopping the minimal-net target on OS X.
Both IPv4 and IPv6 are supported.
Using the minimal-net target on OS X was absolute hell
before I came up with this patch. Now it is painless.
The minimal-net target, as currently written, wakes up the
CPU every millisecond to check for packets, and will only
react in real-time to input from stdin. If you are running
this on a laptop battery, your battery will quickly drain.
This change allows the CPU to idle when there is literally
nothing to do while still being responsive to input from
stein and/or incoming packets. This fix should significantly
improve performance while significantly improving power
usage. Win-win.
Also added `_xassert()` implementation so that the contiki-
provided `assert()` macro will work properly when used
on this platform.
This loads Makefile.target into Makefile so we can check for TARGET==sky
when building this. Compilation for sky fails without it.
