19 * TEST IDENTIFIER : capget02
20 *
21 * EXECUTED BY : anyone
22 *
23 * TEST TITLE : Tests for error conditions.
24 *
25 * TEST CASE TOTAL : 5
26 *
27 * AUTHOR : Saji Kumar.V.R <saji.kumar@wipro.com>
28 *
29 * SIGNALS
30 * Uses SIGUSR1 to pause before test if option set.
31 * (See the parse_opts(3) man page).
32 *
33 * DESCRIPTION
34 * Verify that
35 * 1) capget() fails with errno set to EFAULT if an invalid address
36 * is given for header
37 * 2) capget() fails with errno set to EFAULT if an invalid address
38 * is given for data
39 * 3) capget() fails with errno set to EINVAL if an invalid value
40 * is given for header->version
41 * 4) capget() fails with errno set to EINVAL if header->pid < 0
42 * 5) capget() fails with errno set to ESRCH if the process with
43 * pid, header->pid does not exit
44 *
45 *
46 * Setup:
47 * Setup signal handling.
48 * Pause for SIGUSR1 if option specified.
49 *
50 * Test:
51 * Loop if the proper options are given.
52 * call capget with proper arguments
53 * if capget() fails with expected errno
54 * Test passed
55 * Otherwise
56 * Test failed
57 *
58 * Cleanup:
59 * Print errno log and/or timing stats if options given
60 *
61 * USAGE: <for command-line>
62 * capget02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
63 * where, -c n : Run n copies concurrently.
64 * -e : Turn on errno logging.
65 * -h : Show help screen
66 * -f : Turn off functional testing
67 * -i n : Execute test n times.
68 * -I x : Execute test for x seconds.
69 * -p : Pause for SIGUSR1 before starting
70 * -P x : Pause for x seconds between iterations.
71 * -t : Turn on syscall timing.
