[LTP] [PATCH] syscalls/access01: Set umask value before run case

[Bixuan Cui]

The case will fail when set the umask to 0077 acquiescently in system.
Because the value of actual mode is 'set value' & ~'default value
for the umask' when create dir.
So add 'umask(0022)' in setup().

We do umask(0) in ltp-pan:

# umask
0077

# /opt/ltp/runltp -p -d results -l RUNTEST.log -o RUNTEST.run.log -s access01 -f syscalls > /dev/null

# cat /opt/ltp/results/RUNTEST.log
Test Start Time: Fri Sep 22 14:24:28 2017
-----------------------------------------
Testcase                       Result     Exit Value
--------                       ------     ----------
access01                       PASS       0    

I'm aware that running tests outside of ltp-pan is sometimes useful,
so maybe we could add this to a library rather than in each test
separately? What do you think Cyril?

Regards,
Jan

Yes, I shouldn't run it without runltp script.

Running tests outside ltp-pan should indeed possible but I'm not sure
that we want to change the umask in the test library. Most of the
testcases will run with the more restrictive umask just fine and I would
rather test the system in the default configuration. So changing it in
the test setup in this case sounds reasonable to me.
