-/**********************************************************
- *
- * TEST IDENTIFIER : adjtimex02
- *
- * EXECUTED BY : root / superuser
- *
- * TEST TITLE : Tests for error conditions
- *
- * TEST CASE TOTAL : 6
- *
- * AUTHOR : Saji Kumar.V.R <saji.kumar@wipro.com>
- *
- * SIGNALS
- * Uses SIGUSR1 to pause before test if option set.
- * (See the parse_opts(3) man page).
- *
- * DESCRIPTION
- * Verify that
- * 1) adjtimex(2) fails with errno set to EFAULT if buf does
- * not point to writable memory
- * 2) adjtimex(2) fails with errno set to EINVAL if an attempt
- * is made to set buf.tick to a value < 900000/HZ
- * 3) adjtimex(2) fails with errno set to EINVAL if an attempt
- * is made to set buf.tick to a value > 1100000/HZ
- * 4) adjtimex(2) fails with errno set to EINVAL if an attempt
- * is made to set buf.offset to a value > 512000L
- * (This test case will be executed only if the kernel version
- * is 2.6.25 or below)
- * 5) adjtimex(2) fails with errno set to EINVAL if an attempt
- * is made to set buf.offset to a value < 512000L
- * (This test case will be executed only if the kernel version
- * is 2.6.25 or below)
- * 6) adjtimex(2) fails with errno set to EPERM if buf.mode is
- * non-zero and the user is not super-user.
- *
- * Setup:
- * Setup signal handling.
- * Pause for SIGUSR1 if option specified.
- * Save current parameters in tim_save
- *
- * Test:
- * Loop if the proper options are given.
- * Call test case specific setup if needed
- * call adjtimex with saved timex structure
- * Check return value is between 0 & 5
- * Test passed
- * Otherwise
- * Test failed
- * Call test case specific cleanup if needed
- *
- * Cleanup:
- * Print errno log and/or timing stats if options given
- *
- * USAGE: <for command-line>
- * adjtimex02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
- * where, -c n : Run n copies concurrently.
- * -e : Turn on errno logging.
- * -h : Show help screen
- * -f : Turn off functional testing
- * -i n : Execute test n times.
- * -I x : Execute test for x seconds.
- * -p : Pause for SIGUSR1 before starting
- * -P x : Pause for x seconds between iterations.
- * -t : Turn on syscall timing.
- *

- * OS Test - Silicon Graphics, Inc.
- * Mendota Heights, Minnesota
- *
- * TEST IDENTIFIER: aiotcs02: write/close flushes data to the file
- *
- * PARENT DOCUMENT: aiotds01: kernel i/o
- *
- * AUTHOR: Barrie Kletscher
- *
- * CO-PILOT: Dave Baumgartner
- *
- * TEST ITEMS:
- * for each open flags set used:
- * 1. Multiple writes to a file work as specified for
- * more than BUFSIZ bytes.
- * 2. Multiple writes to a file work as specified for
- * BUFSIZ bytes.
- * 3. Multiple writes to a file work as specified for
- * lower than BUFSIZ bytes.
- *
- * INPUT SPECIFICATIONS:
- * Standard parse_opts supported options.
- *$
- * OUTPUT SPECIFICATIONS
- * Standard tst_res output format
- *
- * ENVIRONMENTAL NEEDS:
- * This program uses the environment variable TMPDIR for the location
- * of the temporary directory.
- *
- *
- * SPECIAL PROCEDURAL REQUIREMENTS:
- * The program must be linked with tst_*.o and parse_opts.o.
- *
- * INTERCASE DEPENDENCIES:
- * NONE.
- *
- * DETAILED DESCRIPTION:
- * Attempt to get some memory to work with.
- * Call testrun writing (BUFSIZ + 1) bytes
- * Call testrun writing BUFSIZ bytes
- * Repeated call to testrun() with decreasing write sizes
- * less than BUFSIZ
- * End
- *
- * Start testrun()
- * Attempt to open a temporary file.
- * Write the memory to the file.
- * Attempt to close the file which also flushes the buffers.
- * Now check to see if the number of bytes written is the
- * same as the number of bytes in the file.
- * Cleanup
- *
- * BUGS:
- * NONE.

Hi!
Pushed with minor changes, thanks.
However the test fails with -i 2 after this patch since on second
iteration since the socket is already bind for the possitive test
because we no longer close the socket after each iteration. Looking at
the bind tests we should move this one into a separate testcase and add
a few more positive tests as well we seem to test only AF_INET,
SOCK_STREAM combination which does not even cover ipv4 nor we attemp to
connect to the socket that have been bind.
> +// SPDX-License-Identifier: GPL-2.0
Changed this to GPL-2.0-or-later to match the original license.
And removed the NULL parameter from the TST_GET_UNUSED_PORT(), since
newlib variant does not have the cleanup callback parameter.

FYI I've added an issue so that this is not forgotten:

Ew, sorry about that. I guess I never ran it with the option as I only tried
what is listed in runtest.
I'll try it with '-i 2'.

Agree, added to my to-do list. I am mostly burning through tests and
converting them to the new library manually.

I thought the original was GPL-2.0 (may be I misread the text, sorry).

Ack, thanks for doing this Cyril. Hopefully the next ones will apply without
edits ;0)
