Hello all, I just stumbled over a little issue using fbsplash. I'm getting a strange progress bar layout and shortly afterwards a segfault whenever I write a percentage (different from 0) into my fbsplash pipe. The reason is quite simple. We're running into a signed/unsigned endless loop problem. Since revision
http://code.metager.de/source/xref/busybox/miscutils/fbsplash.c?r=e4fa7b7965fd574cff2a6a9b877522d613804a38 the type of the counter "i" in fb_drawprogressbar changed from int to unsigned. The typical refactoring issue in doing so is to consequently modify all reverse loops including zero and stopping when reaching -1 like while (i >= 0) i--; As "i" is now unsigned, the condition will always be true and we're getting an endless loop. When doing calculations with pointers depending on the counter we're running into a segfault quite fast... There are two possible fixes of course: either using int again for "i" or breaking the loop when "i" reaches zero. Best regards, Michael -- Dipl. Ing.
