[LTP] [PATCH] openposix: update invalid clock id to accomodate new auxiliary clock ids

[LTP] [PATCH] openposix: update invalid clock id to accomodate new auxiliary clock ids

[Avinesh Kumar]

There can be 8 more clock ids reserved on systems with
CONFIG_POSIX_AUX_CLOCK=y [1]
consequently clock 17 no longer remains an invalid id.

Thanks for fixing this! Because we don't have infrastructure to check kconfig in
open POSIX tests I agree to just bump the value.

nit: FYI I've noticed several times people suggesting to use for links
lore.kernel.org, see kernel commit 05a5f51ca5666 ("Documentation: Replace
lkml.org links with lore"):

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=05a5f51ca566

	Replace the lkml.org links with lore to better use a single source
	that's more likely to stay available long-term.

Therefore link would be:

Thanks Petr, I will keep this in mind from now on.
And I hope this can be fixed during the merge if patch is good as is.

Technically you can have any number of clocks defined by a system that
implements POSIX. So the comment here should be:

"hopefully big enough not to be a valid clock value"

And we may possibly bump it to a larger value as well, e.g. 50

Or we may be a bit smarter, for clock_gettime() or clock_getres() we can
loop starting at 0 until we get EINVAL or cross sufficiently large value.

I thought of implementing something like this. But we get EINVAL for
smaller values also for which clocks are not defined.

./clock_getres_6-2.run-test 
clock_getres(-2147483648, &res);
clock_getres(2147483647, &res);
clock_getres(2147483647, &res);
clock_getres(-2147483647, &res);
clock_getres(-1073743192, &res);
clock_getres(1073743192, &res);
clock_getres(-1, &res);
clock_getres(10, &res);
clock_getres(11, &res);
clock_getres() != -1
clock_getres(12, &res);
clock_getres(13, &res);
clock_getres(14, &res);
clock_getres(15, &res);
clock_getres(16, &res);
clock_getres() != -1
clock_getres(17, &res);
clock_getres() != -1
clock_getres(18, &res);
clock_getres() != -1
clock_getres(19, &res);
clock_getres() != -1
clock_getres(20, &res);
clock_getres() != -1
clock_getres(21, &res);
clock_getres() != -1
clock_getres(22, &res);
clock_getres() != -1
clock_getres(23, &res);
clock_getres() != -1
clock_getres(24, &res);
clock_getres(25, &res);
clock_getres(26, &res);
At least one test FAILED -- see above

Thanks for info. Out of curiosity: I suppose the different approach from the
exact value for LTP Linux tests fixed in 5c0e414511 (which use lib/tst_clocks.c)
is because POSIX tests can be tested for other Unix like tests? Is the POSIX
testsuite intended for BSD or any unix like kernels/OS? If yes, I wonder if
anybody does (and if it even compiles).

Kind regards,
Petr

If I remmeber correctly we got some feedback from Haiku OS devs and BSD
uses LTP as well, even the Linux part to test their Linux compatibility
layer.

[LTP] [PATCH v2] openposix: update invalid clock id to accomodate new auxiliary clock ids

[Avinesh Kumar]

Starting kernel v6.17, there are 8 more auxiliary clock ids reserved on
systems with CONFIG_POSIX_AUX_CLOCK=y [1] and moreover posix systems can
define and support any number of clocks beyond the mandatory ones.
