2017-08-29i2c-tools: don't include linux/i2c-dev.hBartosz Golaszewski
Installing headers from upstream i2c-tools makes it impossible to build the busybox version due to redefined symbols. This is caused by the fact that linux/i2c-dev.h from i2c-tools overwrites the one from linux uapi and defines symbols already defined by linux' linux/i2c.h. Drop this include and simply re-implement the relevant defines from linux/i2c-dev.h in miscutils/i2c-tools.c. Tested by building on systems with and without i2c-tools headers.

2017-08-28kill: add '--' option to separate options from argumentsRon Yorston
Using a negative pid to send TERM to a process group results in an obscure error: $ ./busybox kill -12345 kill: bad signal name '12345' This is intended. Manpage says: ARGUMENTS pid Each pid can be one of four things: ... -n where n is larger than 1. All processes in process group n are signaled. When an argument of the form '-n' is given, and it is meant to denote a process group, either a signal must be specified first, or the argument must be preceded by a '--' option, otherwise it will be taken as the signal to send. However, we did not support "--". Add this capability to BusyBox. function old new delta kill_main 993 999 +6 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Upstream commit: Date: Thu, 30 Oct 2014 11:53:35 +0800 [PARSER] Catch variable length expansions on non-existant specials Currently we only check special variable names that follow directly after $ or ${. So errors such as ${#&} are not caught. This patch fixes that by moving the is_special check to just before we print out the special variable name.
