2019-02-25openrc-init: fix waitpid checksWilliam Hubbs
The do_openrc() function was not waiting properly for the child process which started the runlevel to return. We need to repeatedly call waitpid() until its return value matches the pid of the child process or the child process does not exist. This fixes #216. This fixes #300.

Nanosleep is the safer call to use in case we need to use alarms eventually.

2018-02-24openrc-init: set a default pathWilliam Hubbs
The default path provided by the system if one isn't set only includes "/bin:/usr/bin". This adds the default path setting from sysvinit.

How to reproduce 1-byte overflow: ``` $ FEATURES=-test CFLAGS="-fsanitize=address -O0 -ggdb3" emerge -1 openrc ================================================================= ==1==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7fff0efd8710 at pc 0x000000402076 bp 0x7fff0efd7d50 sp 0x7fff0efd7d40 WRITE of size 1 at 0x7fff0efd8710 thread T0 #0 0x402075 (/sbin/openrc-init+0x402075) #1 0x3cf6e2070f in __libc_start_main (/lib64/libc.so.6+0x3cf6e2070f) #2 0x4013b8 (/sbin/openrc-init+0x4013b8) Address 0x7fff0efd8710 is located in stack of thread T0 at offset 2432 in frame #0 0x401cfb (/sbin/openrc-init+0x401cfb) This frame has 3 object(s): [32, 160) 'signals' [192, 344) 'sa' [384, 2432) 'buf' <== Memory access at offset 2432 overflows this variable HINT: this may be a false positive if your program uses some custom stack unwind mechanism or swapcontext (longjmp and C++ exceptions *are* supported) SUMMARY: AddressSanitizer: stack-buffer-overflow ??:0 ?? ``` The problem here is in the code handling reads from 'init.ctl': ``` int main(int argc, char **argv) { ... char buf[2048]; for (;;) { /* This will block until a command is sent down the pipe... */ fifo = fopen(RC_INIT_FIFO, "r"); count = fread(buf, 1, 2048, fifo); buf[count] = 0; ... } ``` `buf[count] = 0;` writes outside the buffer when `fread()` returns non-truncated read. This fixes #138.

2017-04-17init: send term/kill signals as final step of shutdownWilliam Hubbs
2017-04-13init: fix signal handlingWilliam Hubbs
The only signals we handle are SIGINT and SIGCHLD, so block all others and unblock them in the child process before we start a rurnlevel.
2017-04-12init: add re-exec capabilityWilliam Hubbs
This will allow the re-execution of the init process after upgrading OpenRC.
