Description of problem:
Sanity quicktest comming with libcap is showing these problems with script capabilities:
-----------------------
Shell script got [ =ep] - you should upgrade your kernel
shell scripts can have capabilities (bug)

and shows these failures:

Comment 1 Miroslav Vadkerti 2011-08-15 15:21:56 UTC
The previous libcap si failing the same way so this is not a regression. The question that bothers me the most is why the quicktest is complaining about script capabilities. The ping related issue may be expected but I need a confirmation on this.

Comment 2 Miroslav Vadkerti 2011-08-17 14:59:16 UTC
Update after discussion with sgrubb:
Setting capabilities on shell scripts is not a very nice thing though it is a legal operation so this is not a bug

Comment 3 Steve Grubb 2011-08-17 16:37:58 UTC
I reviewed the test results I am getting with what you have above. Its looks like everything is OK. When it says expect failure and it says FAILED, then that is really passed. With the exception of the shell script failure being a bad test, everything seems to be fine. It took me a little while to see what the test was doing, but it seems ok.

Comment 4 Miroslav Vadkerti 2011-08-18 15:37:49 UTC
Thanks for looking into this. So there is no bug here and we can close this bug report as not a bug :)
