Hello Greg,
After running LTP with Fuego on the LTS kernel 4.4.y, there were
a few test cases failing that I thought needed some investigation.
I reviewed the first one (fcntl35 and fcntl35_64) so far. According to the
comments on LTP's fcntl35.c file (by Xiao Yang <yangx.jy@xxxxxxxxxxxxxx>)
the bug tested by this test case was fixed by:
pipe: cap initial pipe capacity according to pipe-max-size
commit 086e774a57fba4695f14383c0818994c0b31da7c
Author: Michael Kerrisk (man-pages) <mtk.manpages@xxxxxxxxx>
Date: Tue Oct 11 13:53:43 2016 -0700
I backported that patch (see next e-mail), tested again and confirmed that
the patch fixed the bug (or at least the error message in LTP's test).
Before:
fcntl35.c:98: FAIL: an unprivileged user init the capacity of a pipe to 65536 unexpectedly, expected 4096
After:
fcntl35.c:101: PASS: an unprivileged user init the capacity of a pipe to 4096 successfully
Thanks,
Daniel Sangorrin
