Re: [LTP] Buffer Overflow with ftest03 and ftest07

Well, they PASS every time when executed by hand, because TDIRECTORY defaults
to plain "/tmp/" in this case. When executing tests with runltp TDIRECTORY is
se to something like "/tmp/ltp-qnZVs21494/" and then fuss[] is sometimes not
big enough to hold the string and this causes the segfault. Try for yourself:

TDIRECTORY="/tmp/this_name_is_just_too_long" ./ftest03

However deleting the code that creates temporary directories works for me, at
least for ftest03.c. I'll test Jiri's patch asap and try to fix the remaining
corner cases.
