Injector hang

[m3gat0nn4ge]

Hi,

Injector seems to be hanging on Fedora 23 after ~1B instruction tests, selinux is in permissive mode, cpu is Intel(R) Core(TM) i7-4800MQ CPU @ 2.70GHz.

I've tried twice, going to attach using strace this time and see if anything is happening but in the meantime, any ideas?

thanks

Ok .. so it seems to be stopping at the exact same point so I guess it has completed checking all the possible combinations. Attaching with strace gave me a stack of the following:

17738 --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} --- 17738 rt_sigreturn({mask=[]}) = 0 17738 --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} --- 17738 rt_sigreturn({mask=[]}) = 0 17738 --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} --- 17738 rt_sigreturn({mask=[]}) = 0 17738 --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} --- 17738 rt_sigreturn({mask=[]}) = 0 17738 --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} --- 17738 rt_sigreturn({mask=[]}) = 0

This time I also left the terminal active while killing the injector process and saw a stack of output. The summarize command doesn't work however:

Traceback (most recent call last): File "./summarize.py", line 751, in <module> textbox.draw() File "/home/me/Documents/sandsifter/gui/gui.py", line 68, in draw self.gui.box(self.window, self.x, self.y, self.w, self.h, self.color) File "/home/me/Documents/sandsifter/gui/gui.py", line 175, in box window.addch(y + h - 1, x + i, curses.ACS_HLINE, color) _curses.error: addch() returned ERR

@m3gat0nn4ge: For the last error, try using a slightly bigger terminal window.

Anything smaller than 97x40 will probably always lead to the same error, as the draw_infobox function currently works with fixed values:

• it draws one box from offset (37,3) with width 60 (at https://github.com/xoreaxeaxeax/sandsifter/blob/master/summarize.py#L605)
• it writes the help strings to y-offsets 33-39 (at https://github.com/xoreaxeaxeax/sandsifter/blob/master/summarize.py#L755 and the following lines)

Thanks @rupran .. summarize is working, now to analyze the results...
