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>

2017-01-09kill: optimizations for single-applet buildKang-Che Sung
* Fix a bug with a configuration in which the shell's kill builtin would be mistreated as a killall command (i.e. '-q' works, and 'kill process_name' succeeds when it shouldn't): CONFIG_ASH_JOB_CONTROL=y CONFIG_HUSH_KILL=y # CONFIG_KILL is not set CONFIG_KILLALL=y # CONFIG_KILLALL5 is not set * Optimize out unneeded code when the relevant applets are not selected. * Move kbuild lines about shells' kill builtins from Kbuild.src to kill.c, to accompany the new HAVE_SH_KILL macro. I hope this would make maintanence a little bit easier. Signed-off-by: Kang-Che Sung <explorer09@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
