| * i2c-tools: don't include linux/i2c-dev.hBartosz Golaszewski2017-08-291-13/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * kill: add '--' option to separate options from argumentsRon Yorston2017-08-281-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 "--".

* | win32: improvements to implementation of kill(2)Ron Yorston2017-09-271-87/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the implementation of kill(2) so that: - Sending the TERM signal asks the target process to exit. As on Unix it may not comply. - Sending the KILL signal forcibly terminates the target process. - Using a negative pid treats the target process as a process group leader and signals it and all of its descendants. - Using a pid of zero treats the current process as a process group leader and signals it and all of its descendants.

* | kill: use gentler method than TerminateProcess()Johannes Schindelin2017-09-271-1/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Git for Windows' source code recently learned, let's also avoid using TerminateProcess() in BusyBox-w32: it does not allow the killed processes' atexit() handlers to run. Instead, jump through a couple of hoops by injecting a remote thread that executes the ExitProcess() function. This allows the atexit() handlers to run, at which point the exit code of the process can already be queried via GetExitCodeProcess(), and appropriate action can be taken, such as killing child processes.

| | | | | | | | | | | | | | | | It may be necessary to run ps as administrator to get information about processes belonging to other users. The code to detect GetTickCount64 at run-time was imported from Git for Windows.

* | dd: silence warning on 64-bit systemsRon Yorston2017-08-311-3/+3
| | | | | | | | | | | | | | | | | | | | | | On 64-bit systems size_t may be larger than unsigned long, resulting in a warning when -1L is cast to size_t. There's little to be gained from allowing obs and ibs take values larger than will fit in a signed long as the subsequent malloc will probably fail. Limit their range to ULONG_MAX/2.

* | win32: further minor code shrinkRon Yorston2017-08-301-17/+11
| | | | | | | | | | Remove the check for argv being NULL in spawnveq. It shouldn't ever succeed.
* | win32: add a function to find executable on PATHRon Yorston2017-08-301-34/+30
| | | | | | | | | | | | The function find_executable is more generic than needed here: it can search for all matches on PATH whereas we only want the first. Implement find_first_executable to do that.
* | win32: changes to treatment of scriptsRon Yorston2017-08-301-58/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simplify how scripts are detected by parse_interpreter. It now: - uses strtok to parse the line buffer; - returns any options as a single string, not an array of separate options; - returns both the full path of the interpreter and its name. When a script is detected the sequence is now: - if the path to the interpreter refers to an executable run that; - else look up the interpreter name as a applet (if so configured) and run the applet found; - else search for the interpreter name on PATH.
* | win32: shrink code to detect .exe filesRon Yorston2017-08-304-31/+26
| | | | | | | | | | | | | | | | Add a function (has_exe_suffix) to replace explicit code to check if a filename ends with '.exe. or '.com'. Also shrink code that checks for '.exe' or '.com' on PATH in shell's find_command function.
* | win32: make vfork fail at compile-timeRon Yorston2017-08-303-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | Nothing in busybox-w32 uses fork. Remove the implementations of fork, vfork and xvfork so that, for example, enabling cpio pass-through causes an error at compile-time, not run-time. MinGW-w64 defines pid_t, so we don't have to. Ensure code containing xvfork in netcat is disabled when NC_EXTRA is disabled. Otherwise removing the implementation of vfork costs 64 bytes.
* | libbb: exclude more Linux-specific functions from being compiledJohannes Schindelin2017-08-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 7a4491e1f (libbb: don't compile various Linux-specific functions, 2017-08-24), we started excluding a number of Linux-specific functions that handle things like SELinux, ioctls, devices and forking. But we forgot a couple functions that depend on the ones we now excluded. This leads to compile failures with -Werror unless cross-compiling on Linux, due to undefined symbols. To fix this, exclude those functions which depend on the ones that were excluded (they do not have any callers on Windows anyway, so all is good).

* | libbb: don't compile various Linux-specific functionsRon Yorston2017-08-241-0/+2
| | | | | | | | | | | | | | xfuncs_printf.c includes a number of Linux-specific functions. They handle things like SELinux, ioctls, devices and forking. Nothing in busybox-w32 uses them, so don't compile them.

| | | | | | | | Pass-through mode never worked: it uses fork().
* | mode_string: S_IFBLK differs between Windows and UnixJohannes Schindelin2017-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | It is a bit wrong to make that much of a hard-coded assumption, anyway. Maybe a better way would be to test whether the S_IF* constants are in a specific range. But then, it is probably not worth the time to investigate that.

* | xconnect: avoid using getsockname/getpeername on WindowsJohannes Schindelin2017-08-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantics of said functions is a bit different on Windows than on Linux: it takes a `SOCKET` parameter instead of an `int` parameter, as Windows does not use file descriptors for sockets. The callers of these functions are only used in the daemons anyway, though, and those are not compiled in busybox-w32. Therefore, let's simply skip compiling those functions on Windows (as well as `get_lsa()`, which would now be unused otherwise).

* | mingw: accommodate for BusyBox' assumptions about isatty()Johannes Schindelin2017-08-242-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Windows, isatty(fd) determines whether the file descriptor refers to a character device. The thing is: even NUL or a printer is a character device. BusyBox thinks, however, that isatty() only returns non-zero for an interactive terminal. So let's shadow isatty() by a version that answers the question BusyBox wants to have answered.

* | bb_basename: handle mixed slashes correctlyJohannes Schindelin2017-08-241-4/+6
| | | | | | | | | | | | | | | | | | | | | | A path like C:/WINDOWS\system32 was handled incorrectly: it found the forward slash, and then never bothered to look whether there was another (back-)slash later on. This fixes e.g. running BusyBox as C:/test\sh.exe Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Ron Yorston <rmy@pobox.com>
